Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an anti-loosening connector. Background Art

[0002] An electrical connector is a component that builds a bridge of communication between blocked or isolated circuits in a circuit, so that current can flow and the circuit can achieve the predetermined function. Connectors are indispensable components in electronic equipment. With different application objects, frequencies, functions, application environments, etc., the forms and structures of connectors vary, including card-type connectors.

[0003] The cardboard connector in the prior art can be connected or disconnected by just pushing and pulling the male and female connectors, which is very convenient. However, the cardboard connector uses elastic plastic as a snap-on device, and the plug can be pulled out with a little force. If the connected wire is accidentally pulled, it is very easy to become loose, resulting in signal interruption.

[0004] A Chinese patent discloses an electrical connector with an anti-loosening structure (authorization announcement number CN220233617U). The patented technology is provided with a No. 2 spring on the inner wall of the male head, one end of the No. 2 spring is fixedly connected to the dustproof plate, and a hole is provided in the middle of the dustproof plate. The dustproof plate can slide on the inner wall of the male head. Through the cooperation of the No. 1 slide groove, the limit block, the No. 2 slide groove, the partition plate, the pressure block, the No. 1 spring, the connecting rod and the sliding block, the inner wall of the male head is dustproof when the male head and the female head are not connected. The male head is automatically locked after being inserted into the female head, and the female head automatically pops out when the pressure block is pressed;

[0005] However, it has certain disadvantages: the male and female heads are separated by pressing the pressing block to make the female head pop out, and then in actual use, the pressing block is easily accidentally touched due to external factors such as collision, causing the pressing block to squeeze the limit block, thereby causing the male and female heads to loosen.

[0034] The docking plate 22 is in a Z-shape, and pressing its front end can cause the rear end of the docking rod 23 to tilt up, so that it no longer blocks the docking block 24 .

[0035] The working principle of the utility model is as follows: when in use, the insert block 3 is inserted into the female head 2. During this process, the block 7 is pressed into the interior of the slide groove 5. When the block 7 is opposite to the countersunk hole 9, the first spring 6 returns to a relaxed state, and the upper end of the block 7 is stuck in the lower end of the countersunk hole 9, thereby connecting the male head 1 and the female head 2 together; at this time, the docking rod 23 and the docking block 24 are stuck to each other, further improving the connection stability of the male head 1 and the female head 2; when the male head 1 and the female head 2 need to be separated, the baffle plate 14 is pulled upward to separate it from the outside of the first connecting column 18, and then the baffle plate 14 is rotated to stagger the first pressure rod 10, and then one hand presses the first pressure rod 10 downward to push the block 7 away from the countersunk hole 9, and the other hand presses the front end of the docking plate 22, so that the rear end of the docking rod 23 is tilted, and then the male head 1 and the female head 2 are pulled away from each other, respectively, so as to separate the two.
