Waterproof A type USB connector female seat and manufacturing method thereof

Abstract

The invention relates to a waterproof A type USB connector female seat. The waterproof A type USB connector female seat comprises four connecting pins, a rubber core and an injection-molded housing; the rubber core is a rubber core which is integrally injection-molded with the four connecting pins; an inner shell which is integrally assembled with the rubber core and a middle shell which is attached onto at the exterior of the inner shell are arranged in the housing; four elastic sheets are arranged on the upper portion and lower portion of the inner shell; two elastic sheets are arranged at the left portion and right portion of the inner shell; the middle shell is a metal shell; two installation legs are arranged at the left portion and right portion of the middle shell separately; and the inner shell, the middle shell and the housing are integrally injection-molded. The manufacturing method includes the steps that: the entire rubber core is injection-molded; the rubber core is assembled with the inner shell and the middle shell; and the rubber core, the inner shell and the middle shell are arranged in a housing model so as to be subjected to integrated injection molding. According to the waterproof A type USB connector female seat and the manufacturing method thereof of the invention, the integrated injection molding is adopted, and a sealing structure is additionally adopted, and therefore, the assembly gap and structural gap of an original similar product can be sealed, so the product can be waterproof; water can be prevented from passing through the unsealed A type USBconnector female seat and entering a charger, so that a complete waterproof effect can be realized; and thus, the watertightness of the charger can be realized, and the requirements of the mechanicalfunctional and electronic performance parameters of the product can be satisfied.

Description

technical field [0001] The invention relates to an interface plug-in, in particular to a waterproof A-type USB connector female seat and a manufacturing method thereof. Background technique [0002] The existing chargers using the Universal Serial Bus (Universal Serial Bus, abbreviated as USB) output port have higher and higher requirements for the use environment, and can be used safely in harsh environments with high humidity. Due to the structure and process of the A-type USB connector female seat (socket Receptacle), the rubber core is injected separately and then assembled with the connecting pin (the pin is the contact terminal) and then assembled with the shell. There is a gap between the connecting pin and the rubber core. There is a large assembly gap, the rear end of the female seat cannot be waterproof, and the shrapnel structure that fixes the A-type USB connector male (plug) on ​​the housing also has a large structural gap, and its international industrial stand...

Problems solved by technology

Due to the structure and process of the A-type USB connector female seat (socket Receptacle), the rubber core is injected separately and then assembled with the connecting pin (the pin is the contact terminal) and then assembled with the shell. There is a gap between the connecting pin and the rubber core. There is a large assembly gap, the rear end of the female seat cannot be waterproof, and the shrapnel structure that fixes the A-type USB connector male (plug) on ​​the housing also has a large structural gap, and its international industrial standard waterproof level is below IPX7, which cannot It can be used safely in harsh environments with high humidity. There are also great safety hazards in long-term use in general humid environments. Moisture can completely enter the interior of the charger through these assembly gaps and structural gaps, thereby making the electronic components a safe distance. decrease

Cause poor function or short circuit can not be used, and even lead to burning circuit boards, electric shock, fire, explosion, endangering people's lives
