Sealing circuit board of waterproof connector and manufacturing method thereof

Abstract

The invention provides a sealed circuit board of a waterproof connector and a manufacturing method of the sealed circuit board, a connecting terminal is located on the circuit board, the connecting terminal is fixedly connected with the connector in a waterproof mode, the circuit board is located in a sealing box, the sealing box is provided with a sealing cover in a sealing connection mode, the connector comprises a connecting shaft and a connecting sleeve, and the axis of the connecting shaft is fixedly connected with the connecting terminal. The connecting shaft, the sealing cover, the connecting sleeve and the cable are in waterproof connection; the connecting terminal of the circuit board and the connector are sealed and waterproof, and the connecting shaft of the connector is tightly pressed and sealed with the connecting terminal, the sealing cover, the connecting sleeve and the cable through the sealing ring, so that the circuit board is convenient to replace and repair, the whole manufacturing is convenient, the connection is firm and reliable, the outdoor waterproof sealing effect is good, and the integral waterproof effect of the outdoor circuit board and the connecting cable is met.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a sealed circuit board of a waterproof connector and a manufacturing method thereof. Background technique [0002] Existing outdoor electronic products require waterproofing, especially electronic circuit boards that need to be used outdoors and can be easily replaced at any time, but most electronic circuit boards used outdoors are difficult to make waterproof, and the connector is used as a cable or electronic circuit board It is difficult to achieve waterproof and fixed connection between them, making it difficult for electronic products to be used outdoors. Moreover, there are safety problems in outdoor use due to the waterproof connection of cables and circuit boards, and the waterproof treatment of connectors and electronic circuit boards cannot meet the requirements. The circuit board sealing and the sealing operation of the connecting cables are cumbersome, causing ...

AI Technical Summary

Problems solved by technology

[0002] Existing outdoor electronic products require waterproofing, especially electronic circuit boards that need to be used outdoors and can be easily replaced at any time, but most electronic circuit boards used outdoors are difficult to make waterproof, and the connector is used as a cable or electronic circuit board Waterproof and fixed connection between them, it is difficult to achieve both waterproof at the same time, making it difficult for electronic products to be used outdoors

In addition, there are safety problems in outdoor use due to the waterproof connection of cables and circuit boards, and the waterproof treatment of connectors and electronic circuit boards cannot meet the requirements

The circuit board sealing and the sealing operation of the connecting cable are troublesome, resulting in the connector not being waterproof and leaking, which cannot achieve the safe sealing effect of the electronic circuit board used outdoors

[0003] At present, most of the sealed circuit boards of waterproof connectors and their manufacturing methods have unreasonable waterproof structures, and at the same time, they need to be sealed and waterproof. The operation is troublesome, the assembly is not firm, the waterproof level is not up to the standard, the connection is unstable, the manufacturing is complicated, and the production cost is high. , the waterproof quality effect of electronic circuit boards and connectors for outdoor use does not meet the requirements for safe use
