Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a waterproof connector female seat. 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 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.

[0003] In order to simplify the assembly process, the existing connector female socket selects the plug-in method to install the terminal on the insulating part. This not only makes the sealing performance of the connection between the terminal and the insulating part poor, resulting in poor waterproof performance, but also makes it easy for external moisture to enter the interior of the female socket, thereby damaging the female socket and affecting the service life of the female socket. At the same time, when the female socket is installed with the external host, the sealing performance of the installation place is also poor, and it is also easily affected by external moisture and dust. Therefore, it is necessary to further improve the existing female socket structure. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a waterproof connector socket, which can solve the problems of poor waterproofness, short service life and poor sealing performance at the host installation point of the existing socket connector.

[0006] A waterproof connector female seat, including an insulating body, a terminal group, a waterproof ring, a first glue layer and a second glue layer; the front end of the insulating body is integrally concavely formed inwardly to form an insertion cavity, and the bottom of the insertion cavity is provided with a plurality of mounting holes connected to the insertion cavity, and the rear end face of the insulating body is integrally concavely formed inwardly to form a glue groove, and the bottom of the glue groove is integrally concavely formed inwardly to form a plurality of glue dispensing grooves, each of which is connected to the corresponding mounting hole; the terminal group includes a plurality of arranged female seat terminals, each of which is integrally provided with a boss protruding outwardly, the front end of the boss abuts against the rear end face of the glue dispensing groove, the contact portion of the female seat terminal extends forward into the insertion cavity, and the welding wire portion of the female seat terminal extends backwardly out of the insulating body; the waterproof ring is arranged on the rear end face of the insulating body; the first glue layer is arranged in the glue groove and blocks the rear end opening of the glue dispensing groove; the second glue layer is arranged in the glue groove and covers the rear end face of the first glue layer.

[0007] As a preferred solution, the insulating body is integrally extended with a fixing portion, and the fixing portion is provided with a fixing hole that cooperates with the outside.

[0008] As a preferred solution, a mounting groove is integrally formed inwardly on the rear end surface of the fixing portion, and the waterproof ring is embedded in the mounting groove and extends backward out of the rear end opening of the mounting groove.

[0009] As a preferred solution, a right-angle anti-fouling portion is provided on the fixing portion.

[0010] As a preferred solution, the first glue layer is a UV glue layer, and the second glue layer is an epoxy resin glue layer.

[0011] As a preferred solution, the rear end of the wire welding part is welded to the wire material, and a heat shrink tube is sleeved at the welding point between the wire welding part and the wire material.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] A glue groove is formed by an integral inward concave arrangement on the rear end face of the insulating body, and a plurality of glue dispensing grooves are integrally formed on the bottom of the glue groove, and the first glue layer is arranged in the glue groove to block the rear end opening of the glue dispensing groove; the second glue layer is arranged in the glue dispensing groove and covers the rear end face of the first glue layer, so that not only the first glue layer can be used to seal the connection between the female terminal and the glue dispensing groove, so that it has good waterproof performance, but also the first glue layer can be used to fix the installation position of the female terminal. At the same time, the setting of the second glue layer can further enhance its waterproof performance, and the waterproof ring is arranged on the rear end face of the insulating body, so that when the female is installed, the waterproof ring can increase the sealing between the female and the host, thereby preventing external moisture from entering its interior and damaging the female, and effectively extending the service life of the female.
