Connector with novel plug-in structure

Abstract

The invention relates to the technical field of connectors, in particular to a connector with a novel plug-in structure, which comprises a metal shell and a plastic shell, a plurality of terminal mounting columns are arranged on the metal shell in an array manner, the plastic shell is provided with a plurality of mounting cavities, and the terminal mounting columns of the metal shell are inserted into the mounting cavities of the plastic shell. A plug-in concave part is arranged between the terminal mounting columns, the plug-in concave part comprises a plurality of symmetrically arranged T-shaped grooves, a plug-in convex part is correspondingly arranged on the plastic shell, the plug-in convex part is a T-shaped column arranged corresponding to the T-shaped grooves, the T-shaped grooves comprise an outer groove and an inner groove, and clamping hooks are arranged on two sides of a notch of at least one of the outer groove and the inner groove. The T-shaped column comprises an outer column and an inner column which are connected together, the adjacent side faces of the outer column and the inner column abut against the step face of the outer groove, the connector is compact in structure, mold structure design is facilitated, the metal shell and the plastic shell are convenient to assemble and plug, connection is tight, the connection strength is high, looseness is avoided, and stable connection of the terminals in the connector is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a connector with a novel plug-in structure. Background technique [0002] In a radio frequency connector, a differential connector or other connectors, an insulating plastic shell and a metal shell with a shielding function are arranged to be inserted into each other. The welding plate end of the terminal is provided with a circular, oval or notch-shaped columnar structure, and the terminal is installed inside the columnar structure, which not only holds the mechanical properties of the terminal, but also plays the role of shielding overlap connection. The connection method of conventional connectors is generally matched by hooks, buckles, etc., the installation strength is not high, it is easy to loosen or detach, and the size of the connector is large and the outline size is too large. Connection methods such as hooks or buckles leave a fitting gap at the connection, result...

AI Technical Summary

Problems solved by technology

The connection method of conventional connectors is generally matched by hooks, buckles, etc. The installation strength is not high, and it is easy to loosen or disengage. Moreover, the connector is relatively large in size and the outline size is too large

Connection methods such as hooks or snaps leave a fit gap at the connection, resulting in a space for movement, poor terminal connection accuracy, and weak connection
