[0017] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0018] The drawings described herein are used to provide a further understanding of the present invention and constitute a part of this application. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation of the present invention. In the drawings:

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.
[0023] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0024] like Figure 1 As shown, the connector of the embodiment of the present invention includes:
[0025] A connector housing 1 having a plug hole 11 and a locking member is arranged on the end surface of the connector housing 1;
[0026] The wiring harness connection end 2 includes an insertion portion 21 and a locking member arranged on one side of the insertion portion 21. The insertion portion 21 rotates along a first direction to be threadedly connected with the jack 11, and the locking member abuts against the locking member to prevent the insertion portion from rotating along a second direction opposite to the first direction.
[0027] The connector of the embodiment of the present invention provides a locking piece on the end face of the connector housing 1 and a locking piece on the wiring harness connection end. When the insertion portion 21 is rotated in a first direction and threadedly connected with the socket, the locking piece abuts against the locking piece, so that the insertion portion cannot rotate in a second direction, thereby avoiding the connector from loosening. Compared with the prior art, the reliability is higher.
[0028] Specifically, the locking member of this embodiment includes a boss 12, and a countersunk hole is provided on the connector housing 1, and the boss 12 is telescopically arranged in the countersunk hole. After the insertion portion 21 is inserted into the insertion hole 11, the boss 12 can be manually pressed into the countersunk hole and then the insertion portion can be rotated in the second direction to remove the wiring harness connection end from the connector housing.
[0029] Specifically in this embodiment, the boss 12 is connected to the bottom of the countersunk hole through an elastic member. The setting of the elastic member allows the boss 12 to automatically pop out of the countersunk hole when not under pressure, thereby abutting against the locking member to prevent loosening. In addition, the boss 12 of this embodiment is connected to the connector housing to prevent loss.
[0030] The elastic member may be a spring.
[0031] In this embodiment, if Figure 1 As shown, the connector includes two bosses 12 spaced apart on the end surface.
[0032] like Figure 1 As shown, the boss 12 of this embodiment has an inclined surface, and in the first direction, the distance between the inclined surface and the end surface gradually increases. Then, when the insertion portion 21 rotates in the first direction, the boss 12 can be retracted into the countersunk hole under the action of pressure; after the insertion portion 21 rotates past the boss 12, the boss 12 bounces up under the action of the spring, so the wiring harness connection end can only rotate in the first direction.
[0033] The cross-sectional shape of the boss 12 in this embodiment is a right triangle. When the insertion part rotates in the first direction, the stopper can gradually press the boss 12 into the countersunk hole. When the insertion part rotates past the boss 12, the boss can abut against the stopper to prevent the insertion part from rotating in the second direction.
[0034] like Figure 1 As shown, the wire harness connecting end of this embodiment includes an annular sleeve 22 disposed on one side of the insertion portion 21 and abutting against the end surface, and a retaining plate 23 is disposed on the outer surface of the annular sleeve 22 .
[0035] The connector housing 1 of this embodiment is a plastic housing.
[0036] like Figure 1 As shown, the wire harness connection end 2 of this embodiment further includes a tapered sleeve, and the small-diameter end of the tapered sleeve is used for connecting the wire harness 3 .
[0037] Specifically, in this embodiment, the wiring harness connection end 2 is connected to the wiring harness 3; the insertion portion 21 is inserted into the socket 11 of the connector housing 1, and rotated clockwise so that the insertion portion 21 is connected to the socket 11 through a thread. Two bosses 12 are provided on the connector housing 1 of this embodiment, and the bosses 12 have an inclined surface. And the bosses 12 are connected to the countersunk hole of the connector housing 1 through a spring. During the clockwise rotation of the wiring harness connection end 2, the bosses 12 are pressed into the countersunk hole under the extrusion of the retaining plate 23. After the retaining plate 23 rotates past the bosses 12, the bosses 12 pop up under the action of the spring, thereby preventing the wiring harness connection end from rotating in the counterclockwise direction. Therefore, the wiring harness connection end of this embodiment can only rotate clockwise to avoid loosening.
[0038] Moreover, after the wiring harness connection end of the present embodiment rotates to the position abutting against the boss 12, it cannot continue to rotate, indicating that the wiring harness connection end has been connected in place. Therefore, the boss 12 of the present embodiment also plays a positioning role.
[0039] When disassembling, manually press down the bosses on both sides and rotate the wiring harness connection end counterclockwise to disassemble.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
