Description

Technical Field

[0001] The utility model belongs to the field of devices, and more specifically relates to a self-locking insert mounting seat. Background Art

[0002] The plug's insert, also known as a metal connector, spring or contact piece, is a key connection component inside the plug. These small metal pieces are usually precisely mounted on the electrode pins of the plug to ensure stable current transmission. Its design structure can be found in the patent drawing with announcement number CN301938150S.

[0003] In practical applications, the plug needs to fit tightly with the plug, so it is particularly important to accurately locate the plug before assembly. Figure 1 and Figure 2 As shown, a common positioning method is to insert the plug 3 into the socket 2 of the special mounting seat 1. However, in order to simplify the insertion process of the plug 3, the size of the socket 2 is often designed to be slightly larger than the plug 3. Although this design improves the convenience of operation, it also brings a problem: the plug 3 is easy to fall off from the socket 2, thereby affecting the reliability of use.

[0004] In order to solve this problem, we need to explore a new plug positioning solution. This solution should not only ensure the smooth insertion of the plug, but also effectively prevent it from falling off, thereby improving the overall performance of the plug. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a self-locking plug-in mounting seat, which can solve the problem that the plug-in is easy to fall off from the socket and realize the self-locking of the plug-in.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A self-locking plug-in mounting seat comprises a mounting seat, wherein the mounting seat is provided with a socket for inserting the plug-in, the side wall of the mounting seat is provided with a threaded hole connected to the socket in the direction of each socket, and a threaded column is threadedly connected to the threaded hole; the threaded column is hollow inside and a spring is coaxially arranged therein, a sphere is connected to one end of the spring close to the socket, and a limiting hole with a diameter smaller than the diameter of the sphere is provided at one end of the threaded column close to the socket, and the sphere is squeezed by the spring and partially protrudes out of the limiting hole.

[0008] The advantages of this solution are at least that: the threaded column is connected to the mounting seat by threads, and its depth can be adjusted, thereby adjusting the depth of the ball at its front end in the threaded hole. When the plug is inserted into the socket, the ball will give way to the side wall of the plug under the elastic force of the spring, thereby limiting the plug and solving the problem that the plug is easy to fall off from the socket. In addition, the whole process does not require additional operation, and the plug is self-locking.

[0009] The utility model is further configured as follows: one end of the threaded column away from the sphere is recessed inwardly to form an inner hexagonal groove.

[0010] The advantages of this solution are at least that the depth of the threaded column in the threaded hole can be adjusted by a hexagonal screwdriver, the exposed size of the threaded column can be reduced, and the interference with other parts can be reduced.

[0011] In summary, the utility model has at least the following advantages:

[0012] 1. By setting a threaded hole, a threaded column, and setting a spring and a ball in the threaded column, the threaded column is connected to the mounting seat through a thread, and its depth can be adjusted, thereby adjusting the depth of the ball at its front end in the threaded hole. When the plug is inserted into the jack, the ball will give way backwards and abut against the side wall of the plug under the elastic force of the spring, thereby limiting the plug, solving the problem that the plug is easy to fall off from the jack, and the whole process does not require additional operation, realizing the self-locking of the plug.

[0013] 2. By setting the inner hexagonal slot, the depth of the threaded column in the threaded hole can be adjusted by a hexagonal screwdriver, reducing the size of the threaded column exposed outside and reducing interference with other parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] A self-locking insert mounting seat, such as Figure 3 and Figure 4 As shown, it includes a mounting base 1, on which is provided a socket 2 for inserting a plug 3, and a side wall of the mounting base 1 is provided with a threaded hole 4 connected to the socket 2 in the direction of each socket 2, and a threaded column 5 is connected to the threaded hole 4.

[0021] In some embodiments, the threaded column 5 is hollow inside and a spring 6 is coaxially arranged inside. The end of the spring 6 close to the socket 2 is connected to a sphere 7. The end of the threaded column 5 close to the socket 2 is provided with a limiting hole 8 with a diameter smaller than the diameter of the sphere 7. The sphere 7 is squeezed by the spring 6 and partially protrudes from the limiting hole 8. When the threaded column 5 is installed in the threaded hole 4, the depth of the threaded column 5 in the threaded hole 4 can be adjusted by rotation, and then the depth of the sphere 7 at its front end in the threaded hole 4 can be adjusted, so that the part of the sphere 7 protruding from the limiting hole 8 is located in the socket 2. When the plug 3 is inserted into the socket 2, the sphere 7 will give way backwards and abut against the side wall of the plug 3 under the elastic force of the spring 6, thereby limiting the plug 3 and solving the problem that the plug 3 is easy to fall off from the socket 2.

[0022] In some preferred embodiments, one end of the threaded column 5 away from the sphere 7 is recessed inward to form an inner hexagonal groove 9, and the depth of the threaded column 5 in the threaded hole 4 can be adjusted by a hexagonal screwdriver, which is very convenient.

[0023] The working process and beneficial effects of the utility model are as follows: the depth of the threaded column 5 in the threaded hole 4 can be adjusted by rotating, and then the depth of the ball 7 at its front end in the threaded hole 4 can be adjusted, so that the part of the ball 7 protruding from the limiting hole 8 is located in the insertion hole 2. When the plug 3 is inserted into the insertion hole 2, the ball 7 will give way backwards and abut against the side wall of the plug 3 under the elastic force of the spring 6, thereby limiting the plug 3 and solving the problem that the plug 3 is easy to fall off from the insertion hole 2.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
