Description

Technical Field

[0001] This utility model belongs to the field of signal connector technology, and specifically relates to a signal connector with protective function. Background Technology

[0002] A signal connector is an interface element used to transmit electronic signals. It is mainly used to connect electrical signal paths between circuit boards, cables, devices or systems. It plays the role of a "bridge" in electronic devices to ensure the efficient and reliable transmission of signals (such as data, audio, video, control signals, etc.).

[0003] Signal connectors consist of plugs and sockets. The plug and socket are the two core components that make up the connector pairing. They achieve signal transmission and electrical connection through physical mating. The connection between the plug and socket is generally a direct insertion without a locking mechanism, relying on friction for fixation. This connection method has unstable contact, especially in vibration environments, where the signal is prone to poor contact, resulting in poor protection performance and inconvenience for users. Utility Model Content

[0004] The purpose of this invention is to provide a signal connector with a simple structure and reasonable design and protective function in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A protective signal connector includes a socket and a plug for use with the socket. The socket includes an inner core seat and an outer ring seat surrounding the inner core seat. The plug includes an inner core head and an outer ring head surrounding the inner core head. A first fixing mechanism is provided at the top and bottom of the outer ring seat, and a second fixing mechanism is provided at the top and bottom of the outer ring head for use with the first fixing mechanism. The first fixing mechanism includes a positioning block disposed outside the outer ring seat, a limiting groove formed inside the positioning block, a limiting plate slidably connected inside the limiting groove, and a spring and a fixing block respectively fixedly connected to both sides of the limiting plate. One side of the fixing block extends to the outside of the outer ring seat, and one end of the spring is fixedly connected to the inner wall of the limiting groove. The second fixing mechanism includes a strip plate disposed on the outer ring head, a positioning groove formed on the strip plate for use with the positioning block, and a fixing groove formed outside the strip plate for use with the fixing block.

[0007] As a further optimization of this utility model, the inner core seat is used in conjunction with the inner core head, and the outer ring seat is used in conjunction with the outer ring head.

[0008] As a further optimization of this utility model, a connecting rope is fixedly connected to the outside of the plug, and a protective cover for use with the outer ring head is installed at one end of the connecting rope. The top inner wall and bottom inner wall of the protective cover are provided with strip grooves for use with strip plates.

[0009] As a further optimization of this utility model, the outer ring seat and the positioning block are integrally formed, and the outer ring head and the strip plate are integrally formed.

[0010] As a further optimization of this utility model, the fixing block is provided with an inclined surface on the side near the plug, and the inclined surface is used in conjunction with the strip plate.

[0011] As a further optimization of this utility model, the spring is provided in several parts.

[0012] The beneficial effects of this utility model are as follows: During the use of this utility model, the plug can be locked onto the socket through the cooperation of the first fixing mechanism and the second fixing mechanism, thereby reducing the occurrence of unstable connection, especially in vibration environment, where the signal is prone to poor contact.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a signal connector with protective function includes a socket 1 and a plug 2. The plug 2 is used to plug into the socket 1. The socket 1 includes an inner core seat 101, and an outer ring seat 102 is fixedly disposed on the outside of the inner core seat 101. The plug 2 includes an inner core head 21, and an outer ring head 22 is fixedly disposed on the outside of the inner core head 21. The inner core seat 101 and the inner core head 21 are used to plug into each other, and the outer ring seat 102 and the outer ring head 22 are used to cooperate. A positioning block 3 is provided on the outside of the outer ring seat 102, a limiting groove 9 is formed inside the positioning block 3, a limiting plate 10 is slidably connected inside the limiting groove 9, and springs 11 and fixing blocks 4 are respectively fixedly connected to both sides of the limiting plate 10. The outer ring seat 102 and the positioning block 3 are integrally formed, which can significantly protect the connector. To improve the performance and reliability of the signal connector, one side of the fixing block 4 extends to the outside of the outer ring seat 102. One end of the spring 11 is fixedly connected to the inner wall of the limiting groove 9. Several springs 11 are provided. A strip plate 5 is provided on the outer ring head 22. A positioning groove 13 is opened on the strip plate 5 and used in conjunction with the positioning block 3. A fixing groove 14 is opened on the outside of the strip plate 5 and used in conjunction with the fixing block 4. The outer ring head 22 and the strip plate 5 are integrally formed, which can significantly improve the performance and reliability of the signal connector. A bevel 12 is provided on the side of the fixing block 4 near the plug 2. The bevel 12 is used in conjunction with the strip plate 5. The cooperation between the positioning block 3 and the positioning groove 13 can make the plug 2 be inserted into the socket more quickly.

[0020] like Figure 1 , Figure 2 As shown, a connecting rope 6 is fixedly connected to the outside of the plug 2. One end of the connecting rope 6 is equipped with a protective cover 8 that works with the outer ring head 22. The top inner wall and bottom inner wall of the protective cover 8 are provided with strip grooves 7 that work with the strip plate 5. The protective cover 8 is made of rubber. When the signal connector is not needed, the protective cover 8 can be placed over the outside of the plug 2 to prevent dust.

[0021] It should be noted that, in the use of this protective signal connector, when the plug 2 is inserted into the socket 1, the positioning groove 13 aligns with the positioning block 3, and the positioning groove 13 is inserted into the outside of the positioning block 3. When the fixing block 4 contacts the strip plate 5, the strip plate 5 moves along the inclined surface 12 and presses the fixing block 4. At this time, the fixing block 4 drives the limiting plate 10 to move inside the limiting groove 9 and compresses the spring 11. When the plug 2 is fully inserted into the outside of the socket 1, the fixing block 4 aligns with the fixing groove 14. Under the action of the spring 11, the fixing block 4 will be locked into the fixing groove 14. In this way, during use, the plug can be locked onto the socket through the cooperation of the first fixing mechanism and the second fixing mechanism, thereby reducing the possibility of unstable connection, especially in vibration environments, where poor signal contact may occur.

[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
