      . . This invention relates to detachable contact connections and can be used in electrical engineering. It is known electrical: an electrical socket, comprising a body made of electrically conductive material and a sleeve made of spring material with a spring in the radial direction, the end of which goes into the recess of the housing nest. Such a device is characterized by insufficient contact pressure closest to the invention in its technical essence and the achieved result is an electrical plug socket comprising a housing made in the form of a cylinder with at least one contact, a petal formed by a transverse and longitudinal grooves made on a part of the length, spring a sleeve enclosing a body made of spring sheet material with at least one petal facing towards the counter part made with pro ivopolozhnoy seat side sheet materialai Bzaimodeistvu compound: oschim with a contact lobe 2j. This device is characterized by unreliable operation due to insufficient contact pressure. The purpose of the invention is to increase the reliability of the device in operation. The goal is achieved by the fact that the petal of the dinner sleeve is formed by transverse and longitudinal grooves made on a part of the length of the sleeve, while its end cylindrical part covers with a tension the end cylindrical part enclosures. Fig, 1 shows an electrical plug socket, a general view; in fig. 2 - the same, type of cver5su; FIG. A-A, FIG. 2; in FIG. 4 a section BB in FIG. 3; FIG. 5 shows the ram of J3-B in FIG. 3, in FIG. 6 - sleeve, general view; in fig. 7 - the same, bottom view; on fig. 8 - nest body, general view; in fig. 9 - the same, bottom view. The electrical plug socket consists of a cylindrical case. The jacks from an electrical contact material K1, for example, brass, and from the outside of the housing 1, are spring jack 2 from a spring metal sheet, for example steel. The housing of the socket is rolled out of sheet material and has a longitudinal seam 3, in which the opposite sides of the sheet abut one another against each other (Fig. 4,5,6. One of the ends of the housing 1 of the socket has an inlet 4 for insertion of an electrical plug pin, the opposite end section of the socket housing is designed as a cross-sectional V-shaped connecting terminal 5 for inserting an electrical conductor, which, for example, by compressing the connecting terminal 5 can receive mechanical and electrical connections Inie with case 1 socket.
    The housing 1 of the socket has a transverse groove 6 (Fig. 8 and E) and two longitudinal grooves 7 and 8, which are arranged symmetrically with respect to the dividing seam 3 and, together with the dividing seam 3, form two contact lobes 9 adjacent to each other and 10, which lie in the longitudinal direction of the housing 1 of the socket. The free end of the two contact lobes 9 and 10, limited by the transverse groove 6, is turned towards the entrance 4 and is located at some distance from it. Between the inlet 4 and the transverse groove 6 there is an annular terminal portion 11 of the socket body. In contrast to this annular end section 11, which is practically radially inelastic, both contact lobes 9 and 10 are radially elastic with respect to the longitudinal axis of the housing 1, so that the end portions of the contact lobes extending in transverse groove 6 can out. Both longitudinal grooves 7 and 8 are positioned so that both contact lobes 9 and 10 are opposite to the axle: the socket section 12 is pressed, which is located approximately on half of the circumferential surface of the socket housing 1 and is almost radially non-elastic. Adjacent to the longitudinal grooves 7 and 8, the faces of the nest section 12 each form an abutment for the free end portion of one or the other, contact lobe 9 or, respectively, lobe 10, to limit the inward movement of the contact lobes. ,
    The spring sleeve 2 is folded in the form of a pipe from a spring metal sheet and has a longitudinal seam 13 (FIGS. 6 and 7), in which the edges of the metal sheet are facing opposite each other, looking for each other. The longitudinal ball 13 of the spring sleeve 2 is diametrically opposed to the longitudinal seam 3 of the body 1 of the socket, as
    depicted in FIG. 4 and 5, One of the ends of the spring sleeve 2 is connected to the inlet 4 of the housing 1 of the socket. The end section of the spring sleeve 2, which is located between the said end and the transverse groove 14, forms a tension band 15, which mainly covers the inelastic annular end section 11 of the housing 1 of the socket. In the axial direction, the size of the tension tape 15 is somewhat larger than the corresponding size of the annular end section 11 of the housing 1 of the socket, while the tension belt 15 should also overlap the transverse groove b of the housing of the socket rf free end sections of the contact lobes 9 and 10 (Fig. 3) . Thus, part of the tension belt 15 forms an abutment for limiting the outward movement of the contact lobes 9 and 10.
    From the ends of the transverse groove 14 of the spring sleeve 2, two longitudinal grooves 16 and 17 extend, which, together with the transverse groove 14, limit the protrusion 18, the free end of which is turned to the tension belt 15 and, by means of the longitudinal groove 19, is divided into two sections 20 and 21. The protrusion 18 is diametrically opposed to the longitudinal groove of the spring sleeve 2 and is of such a shape that it is not in a compressed state, i.e. Yes, as long as the spring sleeve 2 has not yet been superimposed on the housing 1 of the socket, it was directed inwards relative to the longitudinal axis of the spring sleeve 2. Thus, in the collection state of the plug socket, the protrusion 18 under the influence of its elasticity puts pressure on the contact lobes 9 and 10, In this case, each of the sections 20 and 21 individually exerts pressure on one of the contact lobes to push them inward. The longitudinal grooves 16 and 17, which are located on both sides of the protrusion 18, extend from the transverse groove 14, up to and from. The tension tape 15 of the end 22 of the spring sleeve, due to which the attachment of the step 18 of the plug type, the longitudinal groove 19 is significantly shorter.
    On the longitudinal seam 13 edges forming the spring sleeve 2, there are on each fastening bends 23 and 24, which are opposite to each other in pairs and which enter the hole 25 or, respectively, into the hole in pairs. 26 in the wall of the housing 1 of the socket (Fig.3,5,9 A pair of fastening bends 23 and the corresponding hole 25 are in the area of the tension tape 15 of the spring sleeve 2 or the annular end section 11 of the housing 1 of the socket. Another pair of fastening bends 24 and corresponding The hole 26 is located near the opposite end 22 of the spring sleeve. The holes 25 and 26 are diametrically opposed to the longitudinal seam 3 of the jiyca 1 socket. In order for the fastening bends 23 or 24 to have a horizontal support in the holes 25 and 26 that interact with fastener The bent edges of the holes 25 and 26 are arranged in planes parallel to each other so that the opposite fixing bends 23 or 24, respectively, are parallel to each other (Fig. 5). Holes 25 and 26 should be extruded if used to form Shells 1 nests metal sheet is already pre-and-bent. Using the fastening bends 23, the tension tape 15 of the spring sleeve 2 is rigidly supported on the ring-shaped end portion 11. And, on the contrary, the end 22 of the spring sleeve turned from the tension tape 15 encloses the housing 1 of the socket less firmly or preferably with a small gap.
    Finally, the end of the spring sleeve 2, rotated from the inlet 4, is provided with several other locking curves 27, which diverge from the socket housing 1 and serve to firmly secure the plug socket in the housing of insulating material together with the outer thickening 28.
    The spring lug 18 of the spring sleeve 2. squeezes both contact lobes 9 and 10 of the housing 1 of the socket 1 in direction of the inner side with such a force that the free end portions of the contact petals rest against the edges of the non-rudle slot 12 section (Fig. 3 and 4}. If input 4 the housing 1 of the socket is inserted plug pin, the diameter of which is only slightly smaller than the diameter of the annular end portion 11 of the housing of the socket, the free end portions of both contact petals 9 and 10 rise from the edges of the socket section 12, overcoming resistance-elastic protrusion 18, and the plug pin with Spring protrusion 18 is sufficiently firmly clamped between the inelastic portion 12 of the socket and the contact blades 9 and 10 to provide a slight electrical transient resistance of the contact between the plug pin and the housing of the socket and at the same time to prevent unintentional release. out of the plug pin of the plug socket. Deviation of the contact petals 9. and 10. in the outward direction beyond the permissible degree, for example, if the plug pin is skewed inserted into the plug socket, the mean is prevented. The tensioning strap is 15 studs. sleeves 2, since the tension tape 15. overlaps. the free ends of the lobe lobes 9 and 10 and thus
    forms an abutment for limiting the movement of the contact petals to the outside. Due to this, the overstretching of the spring protrusion 18 of the spring sleeve 2 and the weakening of the stitching spring are also prevented. action Adjoining tightly to the ring-shaped end section 11 of the tension band 15 of the loose sleeve 2 prevents, moreover, the opening 4, in particular, is not widened, in particular, in the area of the longitudinal section 3. of the housing 1 of the socket.
    A particular advantage of the plug socket is that the spring protrusion 18 of the spring sleeve 2 is relatively long and, as a result, the distance force is relatively flat in the diagram. This means that the protrusion 18 of the spring sleeve 2 is prefixed. inward direction. Therefore, when mounting the plug socket, the protrusion 18 gets a significant initial spring stroke and a relatively high elastic pre-tension, even when both contact lobes 9 and 10 are pressed inward as far as possible against the edge of the inelastic portion 12 of the socket. The spring stroke, which the free end of the blunt-end 18 passes when inserting the plug pin into the plug socket, is insignificant compared to the initial spring stroke of the protrusion, therefore the force with which the protrusion presses on the contact lobes 9 and 10j increases only slightly and only slightly degree depends on manufacturing tolerances relative to the size of the inner diameter of the housing 1 socket and the outer diameter of the plug pin. As a result, the named manufacturing tolerances also have practically no effect on the quality of the electrical and mechanical connection between the plug socket and the-inserted plug pin, as well as the plug-up force required for insertion of the plug to overcome the friction between the plug pin and the socket body. This flat spring characteristic also contributes to reducing the influence of all other manufacturing tolerances on the quality of the plug socket and the plug connection achieved with it.
    If turned from the tension tape. 15, the end 22 of the spring sleeve 2 encloses the housing 1 of the socket with a slight gap, the spring characteristic in the distance / force diagram. It has an even flatter appearance, since in this case the springs are not only the protrusion 18, but also, to an insignificant degree, the two end of the spring sleeve between the longitudinal seam 13 and the longitudinal one.
