[0002] There are various types of vehicle connectors on the market, which are used to connect electrical cables on vehicles. In a common female connector, a conductive terminal assembly is fixed in a cavity formed by a connector body. One end of the terminal assembly is clamped to the cable through a ferrule, and the cable extends from a cable hole at the rear end of the connector body.

[0003] However, it was found during use that the internal terminal assemblies and cables of some existing female connectors were not installed very reliably. In particular, when the cable extending from the connector body is pulled in the backward direction, the terminal assembly may be deformed or loosened, which has a negative impact on the reliability of the connection between the cable and the terminal assembly, and may even seriously affect current transmission.

[0004] Therefore, there is still a need to improve the existing connectors to provide more reliable electrical connectors. Summary of the invention

[0062] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0063] Figure 1 An electrical connector 1 according to a preferred embodiment of the present invention is shown. The electrical connector 1 is exemplarily represented as a female electrical connector 1, which is usually used in conjunction with a matching male electrical connector. The electrical connector 1 includes a connector body 10, which includes a front end 11 and a rear end 12 opposite to each other along its longitudinal axis L, wherein the front end 11 generally refers to an end suitable for being adjacent to the male connector for plugging and mating therewith, and the rear end 12 refers to an end of a cable 50 such as a coaxial cable that is assembled in the connector and extends therefrom. In addition, as shown in FIG. Figure 5B As shown, the connector body 10 is formed with an inner cavity, and the terminal assembly 80 can be inserted into the inner cavity of the connector body 10 through an opening formed at the rear end 12 .

[0064] In order to ensure that the terminal assembly 80 can be reliably retained in the inner cavity of the connector body 10, especially to prevent the terminal assembly 80 from being loosened due to pulling the cable 50 extending outside the connector body 10, the electrical connector 1 further includes a rear cover assembly 20, which specifically performs additional retention and locking on the cable 50. Figure 1 As shown, the rear cover assembly 20 is mounted on the rear end 12 of the connector body 10. In a preferred embodiment, the rear cover assembly 20 is matched with the connector body 10 by a snap-fit ​​connection, and the rear cover assembly 20 directly clamps the cable 50, thereby providing a position lock for the cable 50 at the rear end 12. The rear cover assembly 20 is a component that is detachable relative to the connector body 10, and is mounted on the rear end 12 of the body 10 after the cable 50 is connected to the connector body 10. Preferably, the rear cover assembly 20 can be molded using a resin material.

[0065] In a preferred embodiment of the present invention, the rear cover assembly 20 may be a two-piece structure, including a rear cover 30 and a clamping member 40, respectively. Figure 2A and Figure 3A As shown. The rear cover 30 and the clamping member 40 are preferably snap-fitted in a direction perpendicular to the longitudinal axis L. Preferably, the snap-fitted connection between them is detachable. Figure 4A and Figure 4B As shown, when the back cover 30 and the clamping member 40 are fitted together, the two cooperate to form a locking hole 23. When the back cover assembly 20 is installed on the main body 10, the locking hole 23 basically extends in a direction parallel to the longitudinal axis L. The cable 50 connected to the inner cavity of the connector body 10 can extend out of the electrical connector 1 through the locking hole 23.

[0066] The rear cover assembly 20 includes a first engaging structure 21, such as Figure 4A As shown, it is arranged on the side of the rear cover assembly 20. The rear cover 30 and the clamping member 40 are snap-connected by means of a first snap-fit ​​structure 21. In particular, the first snap-fit ​​structure 21 includes two snap-fit ​​positions: a first snap-fit ​​position and a second snap-fit ​​position, wherein in the first snap-fit ​​position, the rear cover assembly 20 is set in its pre-locking state, and in the second snap-fit ​​position, the rear cover assembly 20 is set in its final locking state. The pre-locking state of the rear cover assembly 20 means that the locking hole 23 in the rear cover assembly 20 is in an enlarged state, at which time the cable 50 can easily pass through the locking hole 23, Figure 4B The locking hole 23 in the expanded state can be clearly seen in the figure. The final locking state of the rear cover assembly 20 means that the locking hole 23 of the rear cover assembly 20 is retracted to a size slightly smaller than the outer diameter of the cable 50, so that the cable 50 is locked in the locking hole 23. Figure 6B As shown.

[0067] In addition, if Figure 4C As shown, the rear cover assembly 20 further includes a second snap-fit ​​structure 22. The second snap-fit ​​structure 22 is configured to be snap-fitted when the rear cover assembly 20 is not mounted to a predetermined position on the main body 10, restricting the first snap-fit ​​structure 21 to a first snap-fit ​​position, and when the rear cover assembly 20 is mounted to a predetermined position on the main body 10, the second snap-fit ​​structure 22 is released from the snap-fit, so that the first snap-fit ​​structure 21 can enter the second snap-fit ​​position.

[0068] The two components of the rear cover assembly 20 , the rear cover 30 and the clamping member 40 , are further described in detail below in conjunction with the accompanying drawings. Figure 2A and Figure 2B The rear cover 30 according to a preferred embodiment of the present invention is shown. The rear cover 30 is an integral piece, which has a main body engaging portion 31 for engaging with the main body 10 and a cable locking portion 32 for locking the cable 50.

[0069] Preferably, the main body engaging portion 31 has a transverse wall 311 arranged perpendicular to the longitudinal axis L, and when connected to the connector body 10, the transverse wall 311 is roughly parallel to the end surface of the rear end 12. Two through holes 312 are provided on the transverse wall 311, and the diameters of the two through holes 312 are set to be larger than the outer diameter of the adapter cable 50, so as to allow the cable 50 to pass through. The main body engaging portion 31 also has a longitudinal extension wall 313, on which a pair of clamping holes 314 are formed, which are suitable for clamping with the paired mating protrusions 104 on the connector body. In the process of the rear cover 30 being mated to the main body 10, the longitudinal extension wall 313 of the main body engaging portion 31 is able to elastically deform outwardly so that the clamping holes 314 can be clamped onto the mating protrusions 104. In order to facilitate the elastic deformation outward of the longitudinal extension wall 313, which is a part of the wall provided with the clamping holes, a longitudinal narrow groove 315 is provided on the longitudinal extension wall 313, such as Figure 2A As shown, the longitudinally extending wall 313 is divided into several parts, so that the clamping hole 314 is formed on a part of the cantilevered beam-shaped wall.

[0070] On the other hand, a portion of the rear cover 30 extending toward the rear direction along the longitudinal axis L constitutes a cable locking portion 32, which is used to lock the cable 50. Specifically, the cable locking portion 32 includes a first locking hole half portion 321 forming a locking hole of the rear cover assembly 20, and the locking hole half portion 321 extends a length to the rear side from the through hole 312 on the main body clamping portion 31. A clamping rib that plays a role in strengthening the locking is provided on the inner surface of the first locking hole half portion 321. In addition, the cable locking portion 32 of the rear cover 30 includes a clamping groove 322 located on the outside, and the clamping groove 322 is arranged on both sides of the paired through holes 312, and the clamping groove 322 on each side has two clamping positions, so that the clamping groove 322 constitutes a part of the first clamping structure 21 of the rear cover assembly 20, and the two clamping positions of the clamping groove 322 on each side realize the first clamping position and the second clamping position of the first clamping structure 21.

[0071] In addition, the rear cover 30 is further provided with an insertion hole 323 between the two locking hole halves 321, which is suitable for connecting with the matching slide post 43 in the clamping member 40. The shapes of the slide post 43 and the insertion hole 323 are set to have directionality, so as to ensure that the rear cover 30 and the clamping member 40 are connected together in the correct orientation.

[0072] Figure 3A and Figure 3BThe clamping member 40 of the rear cover assembly 20 used in conjunction with the rear cover 30 is shown. The clamping member 40 is also an integral member, which has a second locking hole half 421. Similarly, the second locking hole half 421 also has a clamping rib for strengthening the locking effect. The second locking hole half 421 of the clamping member 40 and the first locking hole half 321 of the rear cover 30 can be matched together to form a complete locking hole 23 in the rear cover assembly 20. In other words, in the pre-locking state of the rear cover assembly 20, the second locking hole half 421 and the first locking hole half 321 are relatively far away, and in the final locking state of the rear cover assembly 20, the second locking hole half 421 and the first locking hole half 321 are close to each other.

[0073] On the other hand, there are flanges 42 protruding inwardly on both sides of the second locking hole half 421 of the clamping member 40. The flange 42 is another component of the first engaging structure 21 of the rear cover assembly 20. When the rear cover 30 is engaged with the clamping member 40, the flange 42 is suitable for engaging in the engaging groove 322 of the rear cover 30.

[0074] In addition, from Figure 4C (and can be combined with Figure 5B and Figure 6B ) It can be clearly seen that the clamping member 40 also has an elastic arm 41, which extends substantially perpendicularly to the longitudinal axis L. When the snap member 412 at the free end of the elastic arm 41 of the clamping member 40 is in contact with the hole 316 (such as the hole 316) on the transverse wall 311 of the rear cover 30 as shown in FIG. Figure 2A ), the latch 412 of the elastic arm 41 abuts against the rear cover 30, specifically, abuts against the vicinity of the outer edge of the transverse wall 311. At this time, the second engaging structure 22 may include the latch 412 of the elastic arm 41 and the hole 316 on the transverse wall 311. The engagement of the latch 412 and the hole 316 puts the second engaging structure 22 in an engaged state, thereby preventing the clamping member 40 from moving relative to the rear cover 30 in a direction perpendicular to the longitudinal axis L. In other words, when the second engaging structure 22 is in the engaged state, the first engaging structure 21 is restricted to the first engaged position, that is, FIG. 4A to FIG. 4C In the position shown, at this time, the clamping member 40 cannot move any further toward the rear cover 30, the locking hole is in an enlarged state, and the cable 50 can easily pass through the locking hole.

[0075] like Figure 5BAs shown, the release of the engagement state of the second engagement structure 22 is achieved by the protrusion 105 provided on the connector body 10. The protrusion 105 is formed on the rear end 12 of the body 10. When the rear cover assembly 20 is installed to the predetermined position on the connector body 10, that is, when the engagement hole 314 on the rear cover 30 is engaged with the matching protrusion 104 on the connector body 10, the protrusion 105 protrudes into the hole on the rear cover transverse wall 311, thereby pushing the snap member 412 at the free end of the elastic arm 41 out of the hole 316, so that the clamping member 40 is disengaged from the engagement with the rear cover 30. In addition, the clamping member 40 can move relative to the rear cover 30 in a direction perpendicular to the longitudinal axis L, so that the locking hole 33 is reduced, thereby clamping the cable 50 extending out of the body 10.

[0076] The rear cover assembly 20 of the electrical connector 1 according to the preferred embodiment of the present invention can be installed as follows.

[0077] First, the cable 50 connected to the inner cavity of the electrical connector 1 is inserted into the through hole 312 of the rear cover 30. At this time, the first engaging structure 21 is in the first engaging position, that is, the first engaging structure 21 is in the first engaging position. FIG. 4A to FIG. 4C In the position shown, the second engaging structure 22 is in an engaged state. At this time, the rear cover assembly 20 is in a pre-locked state, and the locking hole 23 is in an expanded state, so the rear cover assembly 20 can easily move along the cable 50.

[0078] Next, the rear cover assembly 20 is joined to the rear end 12 of the connector body 10, as shown in FIG. Figure 5A and Figure 5B As shown. Especially from Figure 5B It can be clearly seen that when the back cover assembly 20 is fully installed in the predetermined position of the connector body 10, that is, the card hole 314 on the main body card part 31 of the back cover 30 is fully engaged with the matching protrusion 104 on the connector body 10, and the protrusion 105 on the main body 10 protrudes into the hole 316 on the transverse wall 311 of the back cover 30, so that the card member 412 of the elastic arm 41 is pushed out of the hole 316, so that the card member 412 no longer abuts the edge of the hole 316, thereby releasing the engaging state of the second engaging structure 22.

[0079] Finally, the clamping member 40 is moved in a direction perpendicular to the longitudinal axis L, so that the first engaging structure 21 enters the second engaging position, that is, Fig. 6A and Figure 6BAs shown in the figure, the flange portion 42 enters the second engagement position of the slot 322 in the rear cover 30, and the flange portion 42 of the free end of the elastic arm 41 of the clamping member 40 enters the recess 325 on the transverse wall 311 of the rear cover 30 to release the flexed state of the elastic arm 41. In addition, the area through which the locking hole 23 can pass is reduced, and finally the inner surface of the locking hole 23 is clamped to the outer surface of the sheath of the cable 50, so as to achieve the locking of the cable 50 at the rear end 12 of the electrical connector 1. The locking state of the rear cover assembly 20 relative to the cable 50 can be determined from Fig. 7A and Figure 7B Seen in.

[0080] It should be understood that the subject matter of the present invention is not limited to the female electrical connector 1, but can also be used for electrical connectors of other types or for other purposes. In a preferred embodiment, the flange portion 42 of the clamping member 40 and the card slot 322 on the rear cover 30 constitute a first card structure, but it should be understood that in other embodiments, the first card structure can also include other implementations, such as providing a single buckle portion on the rear cover 30 and providing a card slot on the clamping member 40.

[0081] The electrical connector 1 according to the present invention is easy to use. It only requires the rear cover assembly 20 to be directly inserted into the rear end of the connector body, and the clamping member 40 is pushed toward the rear cover to realize the locking operation of the rear cover assembly 20 without using any special fixture.

[0082] By using the electrical connector 1 with the rear cover assembly 20 according to the present invention, the terminal assembly 80 is not easy to shake or deform in the inner cavity of the connector body 10, especially under the action of backward pulling force, the terminal assembly 80 will not move, which accordingly makes the current transmission stable and the electrical connector 1 more reliable to use.

[0083] The electrical connector 1 with the back cover assembly 20 according to the present invention can provide a large retention force due to the matching structure of the back cover 30 and the clamping member 40. The back cover assembly 20 of the present invention is called a terminal position assurance (TPA) component in some occasions.

[0084] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
