Description

Technical Field

[0001] The utility model relates to the field of electric connectors, and more specifically to an electric connector based on a novel plug installation structure. Background Art

[0002] An electrical connector is a component used to connect electronic devices or electrical components, which can transmit power, signals or data between devices. There are many types of electrical connectors, including plug-type electrical connectors, socket-type electrical connectors, etc. They play a key role in various electronic devices and systems, providing reliable electrical connections and signal transmission.

[0003] During the installation process of existing plug-type electrical connectors, it is usually necessary to install the plug part into the shell. During this process, the positioning of the plug part is very important because it will directly affect the stability and reliability of the electrical connector. If the plug part is not positioned accurately during installation, it may lead to an increase in the time spent on positioning the plug and the shell during installation, thereby reducing production efficiency. In addition, on the one hand, the positioning of the existing socket and shell is more troublesome. On the other hand, since multiple fixing bolts need to be installed, the position of the shell and the plug is prone to change before multiple fixing bolts are installed, thereby increasing the difficulty of installation.

[0007] Thus, the plug part and the housing part are firmly connected.

[0008] Furthermore, two of the two opposite inner side walls of the shell portion are fixed with two of the strip-shaped protrusions.

[0009] Thus, the protruding rib abuts against the semi-cylindrical protrusion, so that the plug portion and the housing portion can be temporarily fixed when the locking bolt is not installed.

[0010] Furthermore, the plurality of strip-shaped positioning posts are distributed in a row at equal intervals.

[0011] Therefore, the positioning effect is good when the plug part is installed.

[0012] Furthermore, the plurality of semi-cylindrical protrusions are distributed at equal intervals in the vertical direction.

[0013] Furthermore, the plurality of protruding ribs are distributed in a row at equal intervals.

[0014] Thereby, the fixing effect between the plug part and the housing part is enhanced.

[0015] Furthermore, both side outer surfaces of the shell portion have recessed portions.

[0016] This makes it easier to grip and install.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1. In the electrical connector of the present application, the protruding rib abuts against the semi-cylindrical protrusion, so that it can achieve a temporary fixing effect when the locking bolt is not installed, thereby making installation more convenient.

[0019] 2. The electrical connector of the present application achieves positioning matching between the shell part and the plug part through the cooperation of the positioning column and the positioning hole and the cooperation of the strip positioning plate and the strip positioning groove. After the positioning matching, the locking bolt is installed, thereby making the installation accurate, stable and more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
