Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, in particular to an electric connector. Background Art

[0002] In electrical connection, various independent modules need to be connected to the final assembly through connectors. The existing connectors are single and independent. When in use, each independent connector needs to be connected to each module one by one. However, when the connector is plugged into the module and the final assembly, if there is a deviation in the direction, it will cause inconvenience in installation. In addition, the existing connector has poor waterproof performance. In addition, a guide structure needs to be set at the port of the male piece connection groove. The existing product guide structure and the shell are an integrated molding structure. During injection molding, the process is more difficult, which increases the production cost. Utility Model Content

[0003] The purpose of the utility model is to provide an electrical connector to solve the problems existing in the background technology.

[0004] To solve this technical problem, the technical solution of the utility model is:

[0005] An electrical connector, comprising a plurality of housing units connected to each other by plug-in components, the housing unit comprising an upper housing and a lower housing, a male piece connection slot is provided in the upper housing, a female piece connection slot is provided in the lower housing, a male connection piece is provided in the male piece connection slot, a female connection piece is provided in the female piece connection slot, and after the upper housing and the lower housing are plugged in, the male connection piece is electrically connected to the female connection piece; characterized in that:

[0006] A clamping edge is provided on the inner wall of the male plate connecting groove, a first sealing ring is sleeved on the male connecting plate, the bottom surface of the first sealing ring abuts against the clamping edge, and a pressure block is pressed on the top surface;

[0007] A guide cover is buckled and connected to the top opening of the mother sheet connection slot;

[0008] A module upper abutment surface is formed on the upper shell, and a module lower abutment surface is formed on the lower shell, a module embedding cavity is formed between the upper abutment surface and the lower abutment surface, and a second sealing ring is arranged on both the module upper abutment surface and the module lower abutment surface.

[0009] Furthermore, the plug-in assembly includes a buckle block, buckle grooves are provided on both sides of the upper shell and the lower shell, and two adjacent shell units are plug-connected to each other through the buckle block.

[0010] Furthermore, the cross-section of the buckle block is an I-shaped structure.

[0011] The above technical solution and the beneficial effects of the utility model are:

[0012] The present application provides a detachable snap-in block so that two adjacent shell units can be spliced ​​together. During installation, there will be no angle deviation, making the installation more convenient. In addition, the detachable snap-in block is provided so that when used separately, the structures of the connectors are consistent, making the plug-in more convenient. In addition, a first sealing ring is sleeved on the male connecting piece to improve its sealing performance. BRIEF DESCRIPTION OF THE DRAWINGS
