AI Technical Summary

Technical Problem

The existing plastic shells are not sealed when connecting the wiring harness, which affects the sealing, protective strength and service life, and is inefficient in connection, which can easily cause the connection head to fall off after long-term use.

Method used

Design a plastic shell with external wiring posts, adopting a complex structure including mounting shell, limiting plate, pressing block, pin rod, clamp, sliding sleeve and return spring. Through the cooperation of these components, the wiring harness is realized. Stable connection and convenient separation.

Benefits of technology

It effectively prevents the problem of the connector head falling off after long-term use, improves the connection efficiency and quality, extends the service life, and improves the practicality of the device.

Abstract

The plastic housing comprises a plastic housing and a second connector, the side surface of the plastic housing is fixedly provided with an installation housing, the inner wall of the installation housing is fixedly provided with a limiting plate, the limiting plate is provided with a through hole in a left-right penetrating manner, and the inner wall of the through hole is slidably provided with a pressing block. The end face of the pressing block is fixedly provided with an ejector rod, the end face of the ejector rod is provided with a clamping block in an extrusion contact mode, and the side face of the clamping block is slidably provided with a sliding sleeve. When an external wire harness needs to be connected with an internal wire harness of the plastic shell, the second connector is taken up and aligned with the first connector, the second connector is pushed to extend into the first connector, then the mounting block extrudes the clamping block to move downwards, when the mounting block moves forwards to a bayonet to be matched with the clamping block, the first reset spring pushes the clamping block to move upwards, and the clamping block is clamped in the clamping block. And the clamping blocks are clamped with the bayonets, so that the connection stability can be ensured, and the second connector is effectively prevented from falling off after long-time use.
