Description

Technical Field

[0001] The utility model relates to the technical field of terminal housings, in particular to a compact and stable terminal housing. Background Art

[0002] Terminal blocks generally refer to electrical connectors, which are mainly used for current transmission and signal transmission. They are also called connectors. The terminal block housing is an indispensable component of electronic equipment. It not only protects the internal electrical components from the influence of the external environment, but also ensures the stability and safety of the electrical connection.

[0003] The terminal housing generally includes a base and a plug hole. The base constitutes the main part of the terminal shell, and the plug hole is used to insert the wire into the conductive terminal. A cover is usually installed at the rear end of the base. The cover is used to support and fix the wire to ensure the stability and reliability of the connection. At the same time, it can also change the outlet direction of the wire, help to arrange and fix the wire neatly, and enhance the appearance of the entire terminal row, making it more neat and professional.

[0004] Currently, the cover plate installed on the base is generally divided into two types: upper cover and lower cover. When the upper cover is installed on the base, it is mostly installed by a single buckle, which has poor stability. At the same time, the existing upper cover has poor coverage between the wire harness connected to the terminal, resulting in a large space occupied by the terminal as a whole. One side of the wire harness is often exposed, resulting in an unsightly overall appearance.

[0005] When the lower cover is installed on the base, although there is a certain degree of wrapping between the wiring harness connected to the terminal, it still uses a single clip installation method, which has poor stability and cannot meet market demand. Utility Model Content
