Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, specifically to a connector with an anti-loosening function in the cover. Background Technology

[0002] A connector is a component used to achieve electrical connections between circuits. Its main function is to build a bridge of communication between circuits that are blocked or isolated, so that current can flow and the circuit can achieve its intended function.

[0003] When the connector is not in use, in order to prevent dust and other impurities from entering the connector and affecting the contacts, a cover needs to be placed on the outside of the connector. When in use, the cover is usually connected to the connector by thread or plug-in. When threaded, the connection time is long, and after frequent plug-in, the cover will loosen and affect the use. Therefore, it is necessary to propose a connector with an anti-loosening function for the cover. Utility Model Content

[0004] The purpose of this invention is to provide a connector with an anti-loosening function for the cover body, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connector with an anti-loosening function, comprising a housing and a sealing cover, wherein a contact element is fixedly connected to the inner wall of the housing, and a sealing cover is inserted into the inner wall of the housing;

[0006] The sealing cover has symmetrically shaped limiting cavities extending through its interior. The inner wall of each limiting cavity is slidably connected to a limiting block. The inner wall of the outer shell has a limiting hole extending through its interior relative to the limiting block. The limiting block extends through into the limiting hole. The sealing cover has sliding cavities extending through its interior on one side of the limiting cavity. The inner wall of each sliding cavity is slidably connected to a T-shaped slider.

[0007] One end of the T-shaped slider extends through into the limiting cavity and abuts against the limiting block. A baffle is rotatably connected to one side of the outer wall of the sealing cover. An arc-shaped block is fixedly connected to one side of the T-shaped slider located on the baffle. An arc-shaped hole is opened through one side of the outer wall of the baffle relative to the position of the arc-shaped block. The arc-shaped block extends through into the arc-shaped hole.

[0008] Preferably, a first spring is fixedly connected to one side of the inner wall of the limiting cavity, and the other end of the first spring abuts against the limiting block.

[0009] Preferably, a second spring is fixedly connected to one side of the inner wall of the sliding cavity, and the other end of the second spring abuts against the T-shaped slider.

[0010] Preferably, a connecting rope is fixedly connected to one end of the outer wall of the outer shell, and the other end of the connecting rope is fixedly connected to the sealing cover.

[0011] Preferably, both the limiting block and the limiting hole are triangular in shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When the sealing cover is inserted into the outer shell, the first spring pushes the limiting block to move into the limiting hole, thus initially limiting and fixing the sealing cover. Then, the rotating baffle pushes the arc-shaped block and the T-shaped slider to move inward. The T-shaped slider moves into the limiting cavity and abuts against the limiting block to prevent the limiting block from moving, thus providing secondary limiting and fixing of the sealing cover. When the sealing cover needs to be removed, the baffle is rotated to separate the baffle from the arc-shaped block. The second spring pushes the T-shaped slider to separate from the limiting block. There is no need to use a threaded connection, which speeds up the connection efficiency. At the same time, the sealing cover is limited a second time, increasing the limiting effect.

[0021] Please see Figures 1-7 This utility model provides a technical solution:

[0022] Example 1: A connector with an anti-loosening function includes a housing 1 and a sealing cover 2. A contact 3 is fixedly connected to the inner wall of the housing 1, and the sealing cover 2 is inserted into the inner wall of the housing 1.

[0023] When in use, the connecting device can be inserted into the housing 1 and connected to the contact 3. When not in use, the sealing cover 2 can be inserted into the housing 1 to prevent the contact 3 from being damaged.

[0024] Example 2: This example differs from the technical solution of Example 1. The sealing cover 2 has a symmetrically shaped limiting cavity inside. The inner wall of the limiting cavity is slidably connected to a limiting block 4. The inner wall of the outer shell 1 has a limiting hole 5 through it relative to the limiting block 4. The limiting block 4 extends through into the limiting hole 5. The sealing cover 2 has a sliding cavity through it on one side of the limiting cavity. The inner wall of the sliding cavity is slidably connected to a T-shaped slider 6. One end of the T-shaped slider 6 extends through into the limiting cavity and abuts against the limiting block 4. A baffle 7 is rotatably connected to one side of the outer wall of the sealing cover 2. An arc-shaped block 8 is fixedly connected to one side of the T-shaped slider 6 on the baffle 7. An arc-shaped hole is through it on one side of the outer wall of the baffle 7 relative to the position of the arc-shaped block 8. The arc-shaped block 8 extends through into the arc-shaped hole.

[0025] In use, after the sealing cover 2 is inserted into the outer shell 1, the first spring 9 pushes the limiting block 4 to move into the limiting hole 5, thereby limiting and fixing the sealing cover 2. At this time, the baffle 7 is in the position of Figure 2 Position, when rotating baffle 7, baffle 7 is at this time Figure 1 Position: The baffle 7 pushes the arc-shaped block 8 into the sealing cover 2 and compresses the second spring 10. The arc-shaped block 8 pushes the T-shaped slider 6 into the limiting cavity and abuts against the limiting block 4, limiting the limiting block 4. When the sealing cover 2 needs to be removed, the baffle 7 is rotated. At this time, the baffle 7 is in position. Figure 2 Position, the second spring 10 pushes the T-shaped slider 6 and the arc block 8 to move outward, so that the T-shaped slider 6 separates from the limiting block 4, and the baffle 7 can be used to remove the sealing cover 2 from the outer shell 1.

[0026] Example 3: This example differs from the technical solutions of Example 1 and Example 2. In this example, a first spring 9 is fixedly connected to one inner wall of the limiting cavity, and the other end of the first spring 9 abuts against the limiting block 4, so that the first spring 9 can be used to push the limiting block 4 into the limiting hole 5.

[0027] A second spring 10 is fixedly connected to one side of the inner wall of the sliding cavity, and the other end of the second spring 10 abuts against the T-shaped slider 6, so that the second spring 10 can be used to push the T-shaped slider 6 to separate from the limiting block 4.

[0028] One end of the outer wall of the outer shell 1 is fixedly connected to a connecting rope 11, and the other end of the connecting rope 11 is fixedly connected to the sealing cover 2, so that the sealing cover 2 can be connected to the outer shell 1 by using the connecting rope 11.

[0029] Both the limiting block 4 and the limiting hole 5 are triangular in shape.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
