Method for realizing single-channel sealing of multi-core connector, and multi-core connector

Abstract

The invention relates to a method capable of realizing single-channel sealing of a multi-core connector, and the multi-core connector. According to the method, signal mounting holes and at least two power mounting holes are formed in shells of a plug end and a socket end; an annular groove allowing an adaptive socket end mounting hole to be inserted is formed between the plug outer shell and the periphery of the front end of the inner mounting hole of the plug outer shell; an inserting surface sealing piece of which the inner peripheral surface is in interference sealing with the periphery ofthe mounting hole is arranged in the annular groove; a conducting wire sealing piece is arranged on a conducting wire at the tail portion of a power / signal assembly in an interference sleeving manner;each power / signal assembly is loaded into the corresponding mounting hole; the conducting wire sealing piece of which the inner circumferential surface is in interference sealing with the conductingwire and the outer circumferential surface is in interference sealing with the mounting hole where the conducting wire is located is pressed in the mounting hole through an end cover at the tail; anda socket is inserted into a plug, so that the inner circumferential surface of each mounting hole of the socket is in interference sealing with the outer circumferential surface of the inserting surface sealing piece. According to the multi-core connector, each loop is sealed by an independent sealing piece, so that the problem of mutual influence among multiple channels in the multi-core connector is solved.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a method capable of realizing single-channel sealing of a multi-core connector and the multi-core connector. Background technique [0002] Due to the particularity of the use of connectors for new energy vehicles, most automotive connectors have higher requirements for sealing performance. Based on this requirement, more and more product designs meet IP68, IP6K9K and other waterproof indicators. At the same time, with the increase in the degree of connector integration, automotive connectors rarely use single-core structure products. Commonly used automotive high-voltage It is also mainly more than 2 cores, and it can reach dozens of cores. Therefore, the use of vehicle connectors is mostly multi-core sealed connectors. [0003] At present, most of the vehicle-mounted multi-core sealed connectors use an integrated sealing structure to meet the sealing requirement...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the vehicle-mounted multi-core sealed connectors use an integrated sealing structure to meet the sealing requirements, that is, the same sealing circuit is used to seal multiple channels at the same time. This sealing method is relatively simple in structure, but the reliability of this sealing structure Relatively poor, because multiple channels share the same sealed circuit, when the seal fails, there will be mutual influence between every two channels, resulting in the failure of all channel functions, and in serious cases, it will cause a short circuit between the channels and damage components
