Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector with a stable installation structure. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one removal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the basis for judgment. Some connectors need to be fixed and installed together with the outside through fixings.

[0003] The fixings on the existing connectors are plugged and fixed together by sliding installation. They are installed together only by the two sides of the fixings and the installation grooves extending forward and backward on the connector. Since the matching accuracy between the fixing size and the installation groove is not high, the fixings are prone to tilt during the plug-in installation process, resulting in the fixings being easily stuck due to interference with the side walls of the installation grooves during the installation process, making it impossible to install the fixings in place, and the installation process is inconvenient. When plugging with an external connector, the installation force between the installation groove and the fixing is small, so it is easy for the connector to be separated from the fixing, affecting the use of the connector. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content

[0033] The front end of the insulating body 10 is integrally recessed with an insertion cavity 101 that cooperates with an external connector, and the left and right outer side walls of the insulating body 10 are both provided with mounting portions 11 that are symmetrically arranged up and down. A mounting groove 102 is formed between the corresponding two mounting portions 11 and the side walls of the corresponding insulating body 10, and the inner side wall of the mounting groove 102 is recessed with an anti-retreat groove 103 that extends forward and backward. A fixing groove 104 that is connected to the mounting groove is integrally recessed inward on the mounting portion 11, and a first anti-retreat portion 12 facing the mounting groove 102 is convexly provided on the rear end of the side wall of the fixing groove 104. A positioning groove 105 that is connected to the fixing groove 104 is recessed inward on the side of the fixing groove 104 away from the mounting groove 102. The positioning groove 105 and the fixing groove 104 both extend forward and backward and pass through the front end surface of the mounting portion 11, and the positioning groove 105 and the fixing groove 104 are arranged at a certain angle.

[0034] In this embodiment, a guide portion 13 is integrally extended forward from the outer front end of the mounting portion 11, and a guide groove 106 communicating with the mounting groove 102 is formed between the two guide portions 13 of the two mounting portions 11 and the side wall of the insulating body 10. A slide groove 107 extending forward and backward is recessed on the inner side wall of the guide groove 106, and the slide groove 107 corresponds to the position of the anti-retraction groove 103. The positioning groove 105 and the fixing groove 104 are arranged vertically.
