[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] This embodiment provides an electrical connector with a locking function. Specifically, see [link to documentation]. Figures 1-9 As shown, the electrical connector with locking function in this embodiment includes a plug 1 and a socket 2. The plug 1 has a plug housing 11, and the socket 2 has a socket housing 21. A first fastening structure 11a is provided on the plug housing 11, and a second fastening structure 21a is provided on the socket housing 21 to fasten in conjunction with the first fastening structure 11a on the plug housing 11. The first fastening structure 11a is configured such that after the socket housing 21 and the plug housing 11 are inserted into place, the relative rotation between the socket housing and the plug housing determines whether or not the fastening is achieved with the second fastening structure 21a.

[0033] Thus, after the plug and socket are inserted into place, the first and second fastening structures can be fastened together by rotating the plug and socket relative to each other in one direction. This not only fastens the plug and socket but also prevents them from coming loose after being fastened, thereby achieving the locking function for the plug and socket connection.

[0034] Specifically, in this embodiment, the plug housing 11 is provided with an annular track forming around the axial direction of the plug housing, and the second fastening structure 21a on the socket housing 21 is a protruding structure that fits into the annular track to slide back and forth along the annular track; wherein, the annular track is the aforementioned first fastening structure 11a.

[0035] In order to achieve a tight fit between the first fastening structure and the second fastening structure after the socket housing and the plug housing are inserted into place, in this embodiment, a sliding groove 110 is formed on the plug housing 11 for the second fastening structure 21a to slide into in order to achieve the insertion of the plug housing and the socket housing; wherein, the sliding groove 110 is formed along the insertion direction of the plug housing and the socket housing.

[0036] Of course, in the electrical connector of this embodiment, the end of the sliding groove 110 is connected to the annular track to form a track structure for the second fastening structure 21a to slide.

[0037] It should be noted that, in this embodiment, the socket housing 21 includes a front housing 211, a main socket housing 212, and an annular component 213. The front end of the front housing 211 has the aforementioned fastening structure 21a. The main socket housing 212 is located behind the front housing 211. The annular component 213 is disposed between the front housing 211 and the main socket housing 212 and can rotate back and forth along the axial direction of the socket housing 21. The annular component 213 is fastened to the front housing 211, and the annular component 213 and the main socket housing 212 are engaged with each other through a meshing structure.

[0038] In this embodiment, as a way to achieve a tight fit between the annular component and the front housing, the front housing 211 is provided with a plug-in portion 21b, and the annular component 213 is provided with a plug-in groove 2130 for the plug-in portion 21b to be inserted and fixed.

[0039] In this embodiment, as the engagement method between the annular component and the main housing of the socket, the inner wall of the annular component 213 has a first engagement structure 2131, and the outer wall of the main housing 212 of the socket has a second engagement structure 2121. The first engagement structure 2131 and the second engagement structure 2121 engage with each other. Once the front housing of the socket housing and the plug housing are fastened together by the mutually cooperating first and second fastening structures, since the annular component and the main housing of the socket are engaged with each other, and the annular component is also inserted and fixed together with the front housing, even if any part of the plug housing or the socket housing (any one of the front housing 211, the main housing 212 of the socket, and the annular component 213) is subjected to a non-human-applied rotational force during operation, it must be after the rotational force is large enough to overcome the engagement force between the annular component and the main housing of the socket. Therefore, by setting the meshing relationship between the annular component and the main housing of the socket, the rotation of the socket housing relative to the plug housing due to non-rotational forces during operation can be avoided, thereby preventing the second fastening structure on the socket housing from becoming loose from the first fastening structure on the plug housing.

[0040] To facilitate manual application of rotational force relative to the socket housing to the annular component by the user, in this embodiment, see [reference needed]. Figure 1 and Figure 2 As shown, an anti-slip structure 2132 is formed on the outer side wall of the annular component 213.

[0041] In addition, in this embodiment, the socket housing 21 also includes a clamping nut 214, which is fastened to the rear end of the socket main housing 212 by means of threaded engagement.

[0042] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
