Plug adopting plastic package terminal component and self-sealing bolt locking power connector

Abstract

The invention provides a plug adopting a plastic package terminal component. The plastic package terminal component comprises a terminal and a first plastic package shell body which is formed by carrying out plastic package on the terminal. The first plastic package shell body is provided with a cavity, wherein a conductive stud on a socket matched with the plug can be inserted into the cavity to be connected with the terminal. The end part, for insertion of the conductive stud, of the first plastic package shell body is provided with a second sealing ring for sealing an inserting surface of the plug and the socket. The end part of the terminal is positioned in the cavity, and the other end part of the terminal protrudes out of the first plastic package shell body. The first plastic package shell is detachably connected with a sealing component through a locking mechanism, and the sealing component is provided with a closed cavity which allows a cable to penetrate through to be connected with the other end of the terminal and can accommodate the terminating position of the cable and the terminal. The plug only conducts plastic package on the terminals independently, the terminating positions of the terminals and the cable are contained in the closed cavity of the sealing component, so an air leakage channel is eliminated, and a self-sealing function is achieved.

Description

technical field [0001] The invention belongs to the technical field of automotive connectors, and in particular relates to a plug and a self-sealing bolt locking power connector using plastic-sealed terminal parts. Background technique [0002] With the rapid development of the new energy automobile industry, the high voltage and high current (25mm 2 and above cable specifications) the safety requirements of components are getting higher and higher. see figure 1 At present, the commonly used connector structure is to lock the terminal 1 of the power connector and the copper bar inside the equipment E through bolts to realize power transmission. With the advantages of high vibration performance and convenient assembly and operation, it is widely used in vibration source components such as motor power, controllers, and reducers. For this type of power connector, the gap between the housing of the connector itself and the housing of the device is generally filled with rubber...

Problems solved by technology

Since the inner core of the cable is generally twisted with multiple strands of copper wire, the inner core of the cable will inevitably be exposed at the crimping or welding position, and it is difficult to design a structure to achieve sealing at this position, and there are tiny gaps in the twisted copper wire itself, so is easily formed as image 3 Leakage channel A shown

In the actual use of the vehicle, if one end of the wiring harness enters water or becomes damp, the water flow or moisture may gradually spread to the other end of the cable along the air leakage channel A, "infecting" and burning the equipment at the other end, causing greater losses
