    [2] Input / output (“I / O”) connectors have been used for many years in the consumer electronics industry, providing connections between computers and peripherals such as CD and DVD players, scanner printers, and the like. This connector application is a parallel connection using a plurality of conductive pins housed in a press-fit terminal, or a universal serial bus ("USB") using flat terminals with contacts slidingly engaged. ) May include a connection. Such sliding engagement can be tolerated in home and business computer applications where the connector is typically located behind or around the computer away from the user's path.
    [3] Recently, the integration of electronic entertainment and computer systems has significantly increased in automotive applications. The vehicle is provided with video tapes, DVD players, MP3 music systems and personal entertainment such as those produced by Sony, Nintendo and Microsoft. In addition to the automotive business, other transportation industries, such as the aircraft industry, are showing the need to equip vehicles and aircraft with other kinds of electronic devices, such as computers, fax machines, and the like.
    [4] In many such applications, a car or aircraft will have an electronic center that will include various circuit boards that support players, devices, or game systems. One or more connectors will be mounted to the circuit board to provide a socket or receptacle into which a user or passenger can insert a plug connector inside to connect an enabling device to a player, system, or the like. Passengers will often insert and remove these plug connectors more than two to four times during travel on a repeated basis. Travel by the vehicle is so high that insertion and removal cycles of the plug connector will add up over the days, weeks and months the vehicle is in use.
    [5] This insertion and removal cycle will add a significant amount of stress on its attachment means of the socket / receptacle and its associated circuit board. Therefore, the present invention is directed to an improved connector assembly for robust vehicle applications that can withstand repeated insertion and retrieval cycles.
    [1] The present invention relates generally to electrical connectors, and more particularly to electrical connectors used in automotive applications with improved retention performance.

    [6] Therefore, it is a general object of the present invention to provide an improved connector assembly for automobiles and aircraft with improved retention performance that firmly holds a socket or receptacle in place on a bonded circuit board, the assembly being inserted and It has a structure for more effectively fixing the connector to the circuit board while resisting the stress added to the upper part during recovery.
    [7] Another object of the present invention is to provide a connector system for a vehicle application comprising a circuit board, a connector attached to the circuit board, and a shroud member for receiving the connector and holding the connector in a predetermined position on the circuit board. To provide.
    [8] It is yet another object of the present invention to provide a robust I / O connector assembly for automotive applications in which the connector assembly is in repeated insertion and removal cycles, the connector assembly having a female socket type connector receiving a plug connector therein. a female socket-style connector, the connector assembly further comprising a protective shroud attached to the circuit board to receive at least partially the female connector, wherein the shroud engages the press arm to engage the outer surface of the female connector. a press arm and exert a retaining force thereon to hold the shroud in any position on the circuit board.
    [9] It is another object of the present invention to provide a shielded housing for a high speed electrical connector, the housing having the form of a hollow shroud with an insulated body which is divided into two sections, one section housing the socket connector and the other section facing the Receiving a plug connector, wherein the housing body portion further comprises a wall portion that separates the housing body portion and provides a means for attaching the housing to a wall or mounting a bulkhead of the vehicle, wherein the housing portion of the shroud extends into the cavity; A hollow cavity having two retaining members for engaging the socket connector portions, the housing portion further comprising a press member formed on an outer wall of the housing, the press member resisting a force applied to the socket connector by the inner retaining member; Oriented on the housing to exert a force on the socket connector have.
    [10] It is a further object of the present invention to provide the above-mentioned shroud with shielding elements, the shielding elements comprising an outer surface of the shroud plated with a conductive metal such that the shroud penetrates the shroud from the circuit board. Surrounding the connector up and through a partition or other support, the outer plated surface of the shroud provides a measure of electromagnetic interference (“EMI”) protection.
    [11] It is still another object of the present invention to provide a conductive housing for a connector mounted on a circuit board, wherein the housing, having a shroud shape, is provided with an accommodating portion accommodating the first connector therein and a first accommodating portion therein. A receptacle for accommodating two connectors, the accommodating portion having an internal cavity formed by a plurality of walls, two of the walls having an upper portion for engaging the first connector and fixing the position of the first connector in the internal cavity; A retaining member formed while the third wall of the receiving portion includes a press member biased to exert a force on the first connector received in the shroud, the retaining member being pressed by the press member to the first connector; It provides a repelling surface that at least partially resists the force applied to the phase.
    [12] The present invention achieves the above objects by its novel and original structure. Thus, in one important aspect of the present invention, a female-style socket connector is provided for mounting on a circuit board. The large shroud member has an interior cavity therein receiving most socket connectors, so that the shroud extends around most socket connectors and the shroud member engages the surface of the circuit board. The shroud includes a press arm for contacting an outer surface of the socket to exert a force on the socket connector, typically a downward force, which forces the socket connector to a specified position on the circuit board so that the socket connector It is reliably soldered or otherwise attached to the circuit board. This downward force counters the reaction force exerted by the shroud member on the socket connector.
    [13] In another main aspect of the invention, the press arm of the shroud is integrally formed with the shroud and extends cantilevered within a slot formed in the outer wall of the shroud. Preferably, the press arm extends horizontally within the shroud top wall and is positioned midway between the two opposite ends of the socket connector. The socket connector itself has an external conductive portion, so that the press arm is plated with a conductive material so that an electrical or ground connection is formed from the shroud to the exterior grounding shell or shield of the socket connector.
    [14] In still another major aspect of the present invention, the shroud includes one or more retaining tabs formed with the shroud and disposed within the inner cavity of the shroud. These retaining tabs join the other outer surface of the socket connector, and preferably this surface will be oriented opposite to the outer surface that the shroud press arm contacts. These retaining tabs not only retain the socket connector in place within the shroud, but also serve to provide an additional point of electrical connection between the shroud and the socket connector. The retaining tab serves to provide the oppositely oriented reaction surface to the press arm and at least partially resist the force applied to the socket connector by the press arm.
    [15] In another main aspect of the invention, a socket connector includes a series of mounting feet received in corresponding mounting holes formed in a circuit board, the socket connector comprising one or more extensions extending from near the mount; The extension serves as a means of limiting the distance that the shroud can contact the circuit board and push down the socket connector to give an anti-overstress measure of the connector system.
    [16] For these and other purposes, features with the advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
    [25] 1 illustrates an overall electronic system portal 20 that may be used in vehicle applications. In this description, the term "vehicle" is given the broadest interpretation and is not limited to conventional land vehicles, but will include aircraft and vessels as well as other crafts.
    [26] The portal 20 will typically be formed in a virtually shown bulkhead or wall 21 facing the interior of the vehicle. In the space behind the partition or wall 21, the circuit board 23 is supported and extends to an electronic device (not shown), which directs the circuit path from the device to the connector 25 supported on the substrate surface 23. A plurality of conductive traces 24 are further included on the surface on the circuit board (FIG. 3).
    [27] Returning to Fig. 3, the connector 25 is a socket or receptacle connector, preferably a variant of IEEE 1394, 1394a or 1394b where the dimensions are very small and the connector must be mounted and supported by a circuit board at a particular mounting distance. to be. Such connectors and their structures are described in detail in US Pat. No. 6,280,209, owned by the assignee of the present invention. The connector 25 may include an internal contact cavity 26 in which a plurality of contacts 27 are supported by an insulating housing 28. The housing 28 may in turn be partially received by the first or internal conductive shield 29 which is partially received by the second or external conductive shield 30.
    [28] The two shields 29, 30 are spaced a predetermined distance from each other to form an annular cavity 32 as shown to receive the outer wall 35 of the corresponding opposing plug connector 36. (Fig. 1). The two shields 29, 30 are preferably at least one spring arm formed with the shield to serve to exert a retention force on the plug connector 36 when the plug connector is inserted into the socket connector 25. (spring arm) 38.
    [29] As shown in FIG. 6, the socket connector 25 extends out of the connector from the terminal 27 and serves to connect the terminal 27 of the connector 25 to the trace 24 on the circuit board 23. As shown in FIG. Terminal tail (40) of the terminal. Although shown as a surface mount tail 40, the tail of the socket connector can be of the through hole received in a plated mating hole on the circuit board. The inner and outer shields 29, 30 also have grounding tabs 42 for connecting to the circuit board 23 (FIG. 3). The socket connector receives a plug connector 36 attached to the cable 19 as shown in FIGS. 1 and 2. The plug connector 36 is shown extending from its normal direction.
    [30] The invention is in the broadest sense an improved connector system comprising a circuit board 25, a connector 25 mounted on the board, and a protective shroud 51 that protects and at least partially houses the connector 25 ( 50). The shroud 51 serves as a protective housing for the connector 25, and Applicants believe that USB or 1394a and 1394b variants must be fastened and supported a certain distance away from the circuit board 23 because the manufacturing tolerances are very strict. It has been found difficult to manufacture housings for small connectors such as connectors. Connectors 25, such as the type shown, have dimensions of, for example, about 0.375 x 0.5 x 0.28 inches. With such small dimensions, it is desirable to protect the connector, but cannot hold it in place on the circuit board. In addition, in such small dimensional environments, the connection area of the socket connector to the circuit board is also very small and susceptible to the high stresses generated by insertion and removal of the plug connector.
    [31] 3 includes a shroud 51 and includes a front face 52 and a rear face 53 that can be separated by an insert mounting wall 55 as shown. The front face 52 is a hollow portion having a passage 54 formed therein and preferably sized to receive the body portion 38 and the mating end 39 of the opposing plug connector 36. The shroud passage 54 is shown formed by a plurality of walls 60, of which the lower wall is a slot for engaging by a latch (not shown) formed on the opposing connector body portion 38. 61 may be provided. The front face 52 is preferably continuous and traverses the slot 61 to provide a means for engaging the latch on the opposing connector 36 if necessary.
    [32] In Fig. 5, the bottom side or surface of the shroud is shown, with the shroud 51 shown to include another inner cavity 65 fitting the connector 25 inward on the opposite side of the mounting wall 55. Can be. Insertion of the connector 25 is made from the bottom of the shroud 51 to form an assembly that can be mounted to the circuit board 23 as shown in FIG. In this regard, the shroud 51 is preferably provided with the mounting flange 66 and the holes 67, so that the shroud 51 is mounted on the circuit board 23 by screws, rivets, solder board fixing, or the like. And may be attached.
    [33] As shown in Fig. 5, the shroud rear cavity 65 has respective arms having an offset (shown extending inward) catch or a free end 70 which is connected to the shoulder 71; And one or more retainers 68 shown in the form of a pair of vertical arms 69. This catch 71 engages the outer shield 30 of the connector 25 by fitting within the pair of corresponding notches 80 formed therein, shown disposed at the outer and lower edges with the connector 25. Let's do it. The catch will support the top surface 81 of this notch 80 and keep the connector 25 in place within the shroud 51. The catch serves as a reaction surface for resisting the force that may be applied on the socket connector 25 by a spring or press arm 90. In this respect, it is desirable to have the flat end of the catch lying in the common plane so that any reaction forces are equal, as shown in FIG. It can be seen that the catch engages the bottom edge of the socket connector while the spring arm engages with the top surface of the socket connector. In this way and in coordination with the mounting flange 66 of the shroud, the shroud serves to protect the socket connector from harmful stresses that may occur due to insertion and removal of the socket connector 25.
    [34] In an important aspect of the present invention, the shroud 51 preferably comprises a spring arm 90 formed integrally with the shroud 51. As best shown in Figures 6 and 7, the spring arm extends into a slot 91 formed in the second half of the shroud and communicates with the rear internal cavity 61. It is shown that the spring arm 90 first extends vertically in the rear face 53 of the shroud and then extends horizontally in the upper wall 92 of the latter half of the shroud 51 and cantileverly extends. The spring arm 90 is connected to a free end 95 with a press member 96 extending downward from the press member into the rear inner cavity 65.
    [35] The upper portion of the press member 96 contacts the outer surface of the outer shield 90 of the connector 25 and in this respect casts or plated some or all of the outer surface of the shroud 51 with a conductive material. It is desirable to. This can be easily done by molding the shroud with a material such as plastic and then plating. By plating, the electrical connection between the circuit board 23 and the shroud 51 can be formed into a connection point occurring inside or along the mounting flange 66. An electrical connection is also formed between the shroud 51 and the connector at the end of the press member 96 and if necessary at the end of the retaining catch 71.
    [36] In operation, the cantilevered spring arm 90 pushes the connector 25 onto the circuit board 23 so as to contact the circuit board so that the connector 25, in particular the terminal tail 40 of the connector, is reflowed. -flow type) Can be soldered by soldering operation. The shroud 51 covers the cover 25 from the vibrations that can be transmitted through the connecting cable 19 and the plug connector 36 by the user as well as the load generated by the insertion and removal cycles of the plug connector 36. It serves as a means to protect it.
    [37] The intermediate mounting wall 55 allows the shroud 51 and the circuit board 23 to be supported on the partition or the mounting wall 21. The shroud back surface 53 may preferably include a recess 98 without extending downward to the surface of the circuit board 23 (FIG. 6). It allows entry into the terminal tail region during the reflow soldering process.
    [38] In order to prevent the connector end tail 40 from being subjected to excessive stress or bending, the outer shield 30 of the connector 25 has a stop surface 100 opposite the circuit board 23 and its terminal tail 40 and It may be provided with over-travel feet 99 (FIGS. 7 and 8) that will limit the downward movement of the connector through the ground tail 42. FIG.
    [39] Although the present invention has been described with respect to an insulating body having a conductive coating, it will be appreciated that other structures are also suitable. For example, the conductive surface of the shroud may be formed by insertion, or the shroud may be diecast with a conductive material. The shroud is generally attached to the circuit board and placed in the shroud in a manner that not only wraps the socket connector (at least three sides) but also relieves insertion and removal stress from being transferred to the soldered connection between the socket connector and the circuit board. To provide a means for retaining the socket connector.
    [40] While the preferred embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that modifications and variations can be made without departing from the spirit and scope of the invention as defined by the enclosed claims.
