    [0001] The invention relates to a housing used for an electrical connector, and further to an electrical connector to be used in combination with the housing.
    [0002] One type of electrical connector is housed in a housing, and is connected to a second electrical connector connected to a cable. The electrical connector includes a mounting portion through which the electrical connector is connected to the second electrical connector. The mounting portion extends generally outwardly through an opening formed in the housing. Therefore, the electrical connector, particularly an electrical connector to be mounted in an automobile, is generally designed to include a seal making close contact with the opening for the purpose of watertightness. An electrical connector as mentioned above is suggested in Japanese Patent Application Publication No. 2001-345153. Fig. 13 is a sectional view of the electrical connector suggested in the publication. An electrical connector 1000 is inserted into a cylindrical portion 1003 formed at a side wall 1002 of a housing 1001 until a flange 1004 of the electrical connector 1000 abuts the side wall 1002. screws 1006 are screwed into threaded holes 1007 through mounting holes 1005 to thereby secure the electrical connector 1000 to the housing 1001. A seal 1008 is compressed by and thereby makes a close contact with an inner surface of the cylindrical portion 1003. In the conventional electrical connector 1000 shown in Fig. 13, the seal 1008 is compressed by and can therefore make a close contact with an inner surface of the cylindrical portion 1003. Therefore, even if the electrical connector 1000 was connected to the cylindrical portion 1003 having an axis extending parallel to an axis of the electrical connector, the electrical connector 1000 does not exert an influence with a degree by which the seal 1008 is compressed in a direction perpendicular to the axis of the electrical connector 1000, ensuring that the seal 1008 is fully compressed uniform, and thus, the seal 1008 provides sufficient sealing performance. However, if the electrical connector 1000 were attached to the housing 1001 in such a condition that the electrical connector 1000 tilts with respect to the cylindrical portion 1003, the seal 1008 can not be compressed uniformly due to the imprecision in a positional relationship between the electrical connector 1000 and the housing 1001, with the result that water is likely to enter the electrical connector 1000 through an insufficiently compressed portion of the gasket 1008. Due to the As mentioned above in the conventional electrical connector, it is an object of the present invention to provide a housing used for an electrical connector capable of preventing the electrical connector from deflecting in position relative to an opening of the housing. wherein the electrical connector 30 is to be mounted to thereby provide uniform sealing performance provided by a seal.

It is preferable that the third part is removably attached to the second part. It is preferable that a length of the second surface in a second direction perpendicular to the first direction is smaller than a length of the first surface in the second direction. It is preferable that the second surface extends toward the aperture from a location apart in the second direction from one end of the first surface further than the other end from the opening in the second direction. In another aspect of the present invention, there is provided an electrical connector to be housed in the above-mentioned housing, comprising a pair of surfaces at opposite ends thereof in the first direction, each of the surfaces making contact with a inner surface of each of the uprights.
    [0006] In yet another aspect of the present invention, there is provided an electrical connector to be housed in the housing, comprising a pair of extensions extending outwardly from opposite ends in the first direction, each of the extensions having an inclined portion causing a distance between the extensions to be smaller towards the opening from the inside of the housing.

    [0012] As illustrated in Figures 1 to 4, an electrical connector 1 is mounted on a printed circuit 20, housed in a housing 30, and then connected to a second electrical connector 100 to which a cable C is connected. The housing 30 is in the form of a box (a lid thereof is not shown). As illustrated in FIG. 4, the housing 30 comprises at least one bottom 312, and a front wall 311 standing at a front edge of the bottom 312 perpendicular to the bottom 312. The front wall 311 is formed with an opening As illustrated in FIGS. 8 to 10, the electrical connector 1 comprises a mounting portion 11 through which the electrical connector 1 is connected to the second electrical connector 100 (see FIG. 1). a body 12, a seal 13 disposed around the mounting portion 11 to provide a water seal, and a plurality of male connector terminals 14 providing mechanical and electrical contact with female connector terminals of the second electrical connector 100. The mounting portion 11 is formed at the front of the body 12. The mounting portion 11 and the body 12 are formed integrally with each other by a mechanical process. resin paste.
    [0013] The mounting portion 11 includes a first mounting portion 111 and a second mounting portion 112 both disposed in a direction in the width direction F1 of the housing 30 (i.e., a direction in the direction of the length of the front wall 311). The first and second mounting portions 111 and 112 both have a hollow interior space 113. The first mounting portion 111 is designed to have a larger cross section than the second mounting portion 112. Each of the first and second portions 111 and 112 mounting is mounted in the second electrical connector 100. The male connector terminals 14 extend into the interior spaces 113. The male connector terminals 14 pass through the body 12 to thereby be fixed relative to the body 12. The body 12 is fixed on the housing 30 so as to fix the electrical connector 1 on the housing 30. The body 12 comprises an upper plate 12a located the highest in the body 12. The upper plate 12a is formed at the its opposite ends with threaded holes 12p in which screws are screwed in order to fix the printed circuit 20 on the electrical connector 1. The upper plate 12a co Including extensions 121 extending from opposite ends of the top plate 12a in the direction of the width Fl. The extensions 121 are designed to have a flat surface, and to be formed with 121p fixing holes. The upper plate 12a is further formed with a pair of projections 122 at its opposite ends to position the printed circuit 20 relative to the electrical connector 1. The body 12 is formed at opposite ends of a bottom 12b with a pair with extensions 123 extending in the direction in the direction of the width F 1 and further backward (i.e. a direction F 2 (see FIGS. 1 and 3) perpendicular to the direction F1). Each of the extensions 123 is formed with a fixing hole 123p.
    [0014] Each of the extensions 123 comprises a side wall 123a extending in the direction F2 in which the electrical connector 1 is connected to the second electrical connector 100, and a front wall 123b designed to be inclined inwards in the direction F2 since the Back to the front of the body 12. Thus, each of the extensions 123 is essentially trapezoidal. The body 12 comprises a pair of side structures 12c having two vertical resin plates spaced from each other parallel to each other, and a plurality of horizontal dividing plates clamped between the vertical plates and spaced apart equal to each other. The lateral structures 12c form a part of the body 12 with a front wall 12d supporting male connector terminals 14.
    [0015] The seal 13 is formed on the front wall 12d to surround the mounting portion 11 at a proximal end of the mounting portion 11. The seal 13 includes a lip seal , and makes close contact with an inner edge 32a of the aperture 32. As shown in Fig. 7, each of the male connector terminals 14 includes a first portion 141 extending linearly forwardly of the body 12 into the first and second mounting portions 111 and 112, the first portion 141 being in the form of a pin, a second portion 142 extending rearwardly of the body 12 to the printed circuit 20, the second portion 142 being L-shaped and a third portion 143 passing through the body 12. The first portion 141 is inserted into and makes electrical contact with a female connector terminal of the second electrical connector 100 mounted in the mounting portion 1 1. The second portion 142 is inserted into a through-hole formed through the printed circuit 20 to thereby establish electrical contact with the printed circuit 20. The third portion 143 is included in the body 12 to thereby allow the first and second second portions 141 and 142 being supported by the body 12. As shown in Figures 8 to 10, the male connector terminals 14 are grouped together in a first group of male connector terminals for the first mounting portion 111, and a second group of male connector terminals for the second mounting portion 112. The first group comprises the male connector terminals 14 in two rows and three rows located at the rear of the two rows. Each of the male connector terminals 14 in both rows is designed to have a larger cross-section than that of the male connector terminal 14 in the three rows. The second group includes the male connector terminals 14 in a die, each having a cross-section substantially equal to that of the male connector terminals 14 in both rows in the first group. As illustrated in Figure 1, the printed circuit 20 is substantially rectangular, and is fixed to the housing 30 by means of screws such that there is a space in which the electrical connector 1 is housed. The printed circuit 20 is formed with a pair of cutouts 21 through which a tool (not shown) is inserted into the housing 30 to screw the electrical connector 1 onto the housing 30.
    [0016] As illustrated in Figure 5, the housing 30 is an aluminum die-cast product, and is in the form of a rectangular parallelepiped box. As mentioned above, the housing 30 is formed at the front wall 311 with the rounded corner rectangular opening 32 through which the mounting portion 11 of the electrical connector 1 protrudes outwardly of the housing 30. As illustrated in FIG. 2, the housing 30 comprises a pair of first uprights 33 and four second uprights 33x over all of which the printed circuit 20 is screwed. As illustrated in FIGS. 4 and 12, the first uprights 33 are formed integrally with the front wall 311 so as to grip the opening 32 in the direction Fl. The first uprights 33 act as the first unit. 30a for positioning the electrical connector 1 with respect to the opening 32 in the direction Fl. More specifically, a space W1 (see FIG. 12) between the first uprights 33 is established according to a width W2 (see FIG. FIG. 12) of the body 12, and the first uprights 33 are positioned according to a length of the opening 32 in the direction F1. Thus, the mounting portion 11 of the electrical connector 1 can be inserted into the opening 32 positioning the body 12 in the direction Fl between the first uprights 33 acting as the first positioning unit 30a. As illustrated in FIG. 2, the first uprights 33 are arranged in alignment with the front corners of the printed circuit 20. As shown in FIG. 4, each of the first uprights 33 is formed on an upper surface 33a with a hole threaded 33p. As illustrated in FIGS. 3 to 5, the electrical connector 1 and the printed circuit 20 are fixed on the housing 30 by aligning the fixing holes 121p (see FIGS. 8 and 9) of the upper plate 12a with the threaded holes. 33p, and further aligning the through holes (see Figures 1 and 2) of the printed circuit 20 with the threaded holes 33p, and then screwing the upper plate 12a (therefore the body 12) and the printed circuit 20 with the screw 121q. As illustrated in FIG. 12, each of the first uprights 33 is designed to have a height H1 measured from a base surface later mentioned 351 to the upper surface 33a. Here, the height H1 is set equal to a height such that the seal 13 (see FIGS. 1 and 8) is just aligned with the opening 32 in a direction in the direction of the height F3 (see FIGS. and 12) of the front wall 311 of the housing 30. Thus, the first uprights 33, particularly the upper surfaces 33a, act as the second unit 30c (see Fig. 3) which is a part of a second unit of positioning for positioning the electrical connector 1 with respect to the opening 32 in the direction F3. The above-mentioned height H1 is set equal to a height H2 measured from a bottom surface of the extensions 123 through which the extensions 123 make contact with the base surfaces 31, to a lower surface of the extensions. 121 and therefore the upper plate 12a. The printed circuit 20 is fixed on the housing 30 by being further screwed on the second uprights 33x illustrated in Figures 1 and 2. The printed circuit 20 is fixed on the second uprights 33x at the central and rear corners at the edges opposite in the Fl direction (see Figure 2). As illustrated in FIGS. 3 to 6, a pair of first L-shaped blocks 35 for positioning the electrical connector 1 is formed on the bottom 312 of the housing 30. The first blocks 35 are located outside the housing 30. opening 32 in the direction Fl. The first blocks 35 are in one piece at the front with the first uprights 33. As mentioned below in detail, the housing 30 comprises a pair of guide passages 34 (FIG. see Figure 6) allowing the electrical connector 1 at the extensions 123 to slide toward the opening 32 from the inside of the housing 30, ensuring that the mounting portion 11 can be inserted into the opening 32 without the 'Spread in the directions Fl and F3. As illustrated in FIG. 6, each of the guide passages 34 is defined by a first surface 351f with which the extensions 123 of the electrical connector 1 make contact at a lower surface thereof, a second surface 363 located above and parallel to the first surface 351f, and a third surface 352a perpendicular to the first surface 351f. The first surface 351f is provided by a first portion 351 of the first block 35, and the third surface 352a is provided by a second portion 352 of the first block 35. A distance in the direction F3 between the first surface 351f and the second surface 363 is designed to allow the extension 123 of the electrical connector 1 to slide between. A distance in the direction Fl between the third surfaces 352a is designed to allow the extensions 123 to slide between. The first surfaces 351f are designed to have a height relative to the bottom 312 such that the seal 13 aligns with the opening 32 in the direction F3. As illustrated in FIG. 4, each of the first blocks 35 is formed at the first surfaces 351f with a threaded hole 351p. The electrical connector 1 is fixed on the housing 30 by putting the extensions 123 on the first surfaces 351f so that the fixing holes 123p 123 extensions align with the threaded holes 351p, and screwing the extensions 123 on the first blocks 35 by means of the screws 123q (see Figure 3). When the electrical connector 1 is fixed on the block 1, the seal 13 aligns with the opening 32 in the direction F3. Thus, the first surfaces 351f act as the first unit 30b which is a part of the second positioning unit mentioned above. As illustrated in Figure 6, the housing 30 further includes a pair of second L-shaped blocks 36. Each of the second blocks 36 has a first portion 361, and a second portion 362 extending from the first portion 361. The first portion 361 in each of the second blocks 36 is screwed to an upper surface of the second portion 352 of the first block 35 so that the second portion 362 extends beyond the second portion 352 inwardly of the housing 30 into the the direction Fl, allowing the second part 362 to define the second surface mentioned above 363.
    [0017] As illustrated in Figures 3 and 4, the second blocks 36 and therefore the second surfaces 363 are designed to have a length smaller than a length of the first surface 351f in the direction F2. On the other hand, the second surfaces 363 extend towards the opening 32 from a location apart in the direction F2 from one end of the first surface 351f located further than the other end of the opening 32 in the second direction F2. More specifically, as illustrated in FIG. 4, each of the second surfaces 363 extends only above a central area 351c of the first surface 351f, and does not extend over a rear area 351a and a front zone 351b of the first surface 351f.
    [0018] That is, the rear area 351a and the front area 351b of the first surface 351f are exposed. Each of the second blocks 36 is designed to have a width (a length in the direction F1) such that the threaded hole 351p is exposed (i.e., not covered by the second block 36) so that a tool can be inserted into the blank 21 (see Figure 2) of the printed circuit 20 to screw the extension 123 on the first surface 351f. As illustrated in FIGS. 5 and 6, a distance between the first surface 351f and the second surface 363 is designed to be slightly larger than a thickness of the extension 123 to allow the extension 123 to slide in the Guide passage 34. As illustrated in FIGS. 3 and 4, a distance between the third surfaces 352a in the direction F1 is defined as a function of a distance between the side walls 123a of the extensions 123. More especially, a distance between the third surfaces 352a in the direction Fl is defined to allow the extensions 123 to slide in the guide passages 34, as previously mentioned. Each of the third surfaces 352a includes an inclined portion 37 (see Fig. 4) causing a distance between the third surfaces 352a to be smaller at a location closer to the opening 32 relative to the interior of the housing 30. Each of the third surfaces 352a is continuous to the first upright 33 through the inclined portion 37, as illustrated in FIG. 4. A process of placing the electrical connector 1 in the housing 30 is explained in FIG. -Dessous. First, as shown in Fig. 11A, the printed circuit 20 on which the electrical connector 1 is mounted is brought above the housing 30 such that the electrical connector 1 faces the housing 30. Next, the extensions 123 of the electrical connector 1 are positioned above the rear zones 351a of the first surfaces 351f.
    [0019] Then, as shown in FIGS. 11B and 12, the extensions 123 of the electrical connector 1 are placed on the rear areas 351a. If the second blocks 36 have a length in the direction F2 such that the second surfaces 363 cover the rear zones 351a, since the second blocks 36 interfere with the extensions 123, it is difficult to place the extensions 123 on the rear zones 351a of the first 351f surfaces. However, the rear areas 351a are not covered by the second surfaces 363, i.e. are exposed at an interior space of the housing 30, and the extensions 123 can be easily placed on the rear areas 351a of the first surfaces 351f. Thus, the body 12 is now in a condition to slide toward the opening 32 in the direction F2. Then, the body 12 is slid towards the opening 32 on the first surfaces 351f, that is to say along the guide passages 34.
    [0020] As illustrated in FIG. 6, since the extensions 123 of the electrical connector 1 slide along the guide passages 34 defined by the first surface 351f, the second surface 363 and the third surface 352a, the body 12 can reach the opening 32 without floating above the first surfaces 351f. Therefore, it is possible to prevent the body 12 from tilting in the direction F3, especially to prevent the mounting portion 11 from tilting obliquely upward (or downward) relative to the opening 32 in the direction F3. On the other hand, since the extensions 123 are guided by the third surfaces 352a while sliding along the guide passages 34, it is possible to prevent the body 12 from tilting with respect to the opening 32 in the direction Fl. As shown in Figures 4 and 9, the extensions 123 slide along the guide passages 34 through the rear areas 351a, the central areas 351c and the front areas 351b in that order. When the front walls 123b of the extensions 123 arrive at the front zones 351b, the front walls 123b abut with the inclined portions 37, and thus the extensions 123 are guided along the inclined portions 37. Therefore, it is possible directing the body 12 in the direction F2 accurately to the opening 32 located between the first uprights 33 simply by causing the body 12 to slide along the guide passages 34. Then, as shown in Figures 3 and 11C , the electrical connector 1 slides along the guide passages 34 to come into contact with the front wall 311, and thus, the mounting portion 11 of the electrical connector 1 protrudes outside the housing 30 through the opening 32. In this situation, as illustrated in FIG. 3, the body 12 is clamped between the first uprights 33 with the side structures 12c which come into contact with interior surfaces (or opposite) of the first amounts 33.
    [0021] As illustrated in FIGS. 1 and 3, the body 12 can be positioned in the direction Fl by coming into contact with the first uprights 33 acting as the first positioning unit 30a. Moreover, since the first uprights 33 acting as the first positioning unit 30a are spaced from each other by a distance W1 defined as a function of the width W2 of the body 12, the body 12 can be clamped between the first uprights 33 with the lateral structures 12c of the body 12 coming into contact with the first uprights 33, ensuring that the body 12 can not be displaced the direction Fl. Thus, the body 12 clamped between the first uprights 33 allows the seal 13 to align accurately with the inner edge 32a of the opening 32 in the direction Fl.
    [0022] As illustrated in Figures 4 and 12, when the mounting portion 11 is mounted in the aperture 32, the attachment holes 123p of the extensions 123 align with the threaded holes 351p of the first surfaces 351f, and 121p of the upper plate 12a align with the threaded holes 33p of the first uprights 33. As mentioned above, the first uprights 33 act as the first positioning unit 30a to position the electrical connector 1 by relative to the opening 32 in the direction Fl, and therefore, the electrical connector 1 can be positioned in the direction Fl simply by being inserted between the first uprights 33.
    [0023] Furthermore, the electrical connector 1 can be positioned in the direction F3 by putting the extensions 123 on the first surfaces 351f and / or by mounting the extensions 121 on the upper surface 33a of the first uprights 33. Then, the electrical connector 1 is fixed on the housing 30 by means of the screws 123q (see Fig. 3) inserted into the threaded holes 351p through the fixing holes 123p, and further by the screws 121q (see Fig. 3) inserted into the threaded holes 33a across the fixing holes 121p of the extensions 121. The printed circuit 20 on which the electrical connector 1 is mounted is fixed on the housing 30 by screwing the printed circuit on the second uprights 33x.
    [0024] Since the body 12 is secured to the first surfaces 351f through the extensions 123 by means of the screws 123q (see Fig. 3), it is possible to prevent the body 12 from moving and / or tilting. the direction F3. Moreover, since the upper plate 12a is fixed to the first uprights 33 by means of the screws 121q (see FIG. 3), it is also possible to prevent the body 12 from moving and / or from tilting in the direction F3. As mentioned above, the body 12 of the electrical connector 1 is positioned in the direction Fl by means of the first positioning unit 30a, and further positioned in the direction F3 by means of the second positioning unit comprising the first unit 30b and the second unit 30c. Thus, the seal 13 disposed around the mounting portion 11 may be aligned with the inner edge 32a of the opening 32 in the directions Fl and F3. Since the body 12 of the electrical connector 1 can be positioned with respect to the opening 32 in the directions Fl and F3, it is possible to prevent the electrical connector 1 from deflecting in position relative to the opening 32 of the housing 30. Therefore, the housing 30 according to the preferred embodiment of the present invention allows the seal 13 to establish a uniform and close contact with the inner edge 32a of the opening 32. In the present embodiment, the first uprights 33 are adapted to act as the first positioning unit 30a for positioning the electrical connector 1 with respect to the opening 32 in the direction F1. Since the first uprights 33 are adapted to stand in order to grip the opening 32, it is not necessary to prepare a particular space to be occupied by the first positioning unit 30a. The upper surfaces 33a of the first uprights 33 act as the second unit 30c (see Fig. 3) which is a part of the second positioning unit for positioning the electrical connector 1 with respect to the opening 32 in the direction F3. Thus, the first uprights 33 act not only as first positioning unit 30a in order to position the electrical connector 1 with respect to the opening 32 in the direction F1, but also as a second positioning unit in order to position the electrical connector 1 relative to at the opening 32 in the direction F3. It is therefore not necessary to prepare a particular space to be occupied by the second unit 30c, ensuring that a space in the housing 30 can be saved. In addition, since the housing 30 is designed to include the guide passages 34 for guiding the mounting portion 11 of the electrical connector 1 to the opening 32, it is possible to prevent the body 12 from tilting with respect to the direction F2 while the body 12 slides along the guide passages 34. Thus, the mounting portion 11 can advance rectilinearly towards the opening 32, and the seal 13 disposed around the portion of mounting 11 can therefore establish a uniform contact with the inner edge 32a of the opening 32, and be uniformly compressed. This ensures that the electrical connector 1 can be connected to the housing 30 without damaging the seal 13.
    [0025] As illustrated in Fig. 3, the housing 30 according to the present embodiment is adapted to include the first unit 30b and the second unit 30c to secure the electrical connector 1 to the housing 30. Note that the housing 30 may be adapted to include one of the first unit 30b and the second unit 30c. It is preferable that the housing 30 includes the first and second units 30b and 30c, because the first and second units 30b and 30c position the electrical connector 1 relative to the opening 32 in the direction F3, and further provide a improved resistance of the upper plate 12a and the bottom 12b of the electrical connector 1 against a compressive force exerted on them when the electrical connector 1 is connected to the second electrical connector 100 (see Figure 1). As illustrated in FIGS. 3 and 6, the first surfaces 351f and the second surfaces 363 are defined by the first blocks 35, and the third surfaces 352 are defined by the second blocks 36.
    [0026] For example, it is assumed that the case 30 illustrated in FIG. 1 is manufactured by the die-casting process of aluminum. If a die used for the die-casting of the housing 30 is open upwardly on the atmosphere, i.e., the die is open in the direction F3, since the spaces defined by the first surfaces 351f, the second surfaces 363 and the third surfaces 352 as guide passages 34 extend in the direction Fl perpendicular to the direction F3, it is difficult to form in one piece the first and second blocks 35 and 36 on the bottom 312 of the housing 30. Thus, it is possible to design the housing 30 to include the guide passages 34 forming the second blocks 36 separately from the first blocks 35, and screwing the second blocks 36 on the first blocks 35. , the housing 30 may be adapted to include the guide passages 34 regardless of the direction in which a die is opened, and thus other portions in the housing 30 may be easily formed. The first positioning unit may be designed to include a single first upright 33 located outside the opening 32 in the direction F1, in which case the first upright 33 is arranged such that when the electrical connector 1 is arranged in contact with the first upright 33, the mounting portion 11 of the electrical connector 1 is arranged in alignment with the opening 32.
    [0027] INDUSTRIAL APPLICATION The casing according to the present invention is preferably used for an electrical connector having a watertightness in the case where an electric circuit necessary to prevent the penetration of water into it is housed in the casing. . In particular, the housing according to the present invention is adapted to an electrical connector to be mounted in an automobile operating in highly changing environments. 35
