Abstract
A kind of waterproof A types USB connector female seat, including the A type USB connector female seats being made of four connection pins, glue core and housings equipped with fixed feet, the totally-enclosed waterproof case that ultrasonic bonding one is used by upper waterproof case and lower waterproof case is equipped in housing outer surface, the through hole of four connection pin installations corresponding with lower waterproof case is assembled using interference fit, forms waterproof sealing structure；The socket of the fixed feet of housing installation corresponding with lower waterproof case is assembled using interference fit, forms waterproof sealing structure.Manufacturing method has following steps：1) the upper and lower waterproof case of injection molding；2) fixed feet of four connection pins and housing and lower waterproof case interference fit are assembled；3) it is using ultrasonic bonding that upper and lower waterproof case is welded.The utility model effectively avoids moisture from entering electronic equipment internal by unsealing A type USB connector female seats, obtains significant completely waterproof effect with lower cost, waterproofing grade is in more than IPX4.
Description
Technical field
The utility model is related to interface card, more particularly to a kind of waterproof A types USB connector female seat.
Background technology
The existing electronics using Universal Serial Bus (universal serial bus, initialism USB) output port
The use environment of equipment is varied, and the requirement to use environment is higher and higher, can make safely in the adverse circumstances of high humility
With.Due to the structure and processing procedure of A type USB connector female seats (socket Receptacle) be after the independent injection molding of glue core first with even
Pin (pin pin i.e. contact terminal) assembling is connect, then is assembled with housing, is connected between pin and glue core there are larger assembly clearance,
Female seat rear end can not waterproof, and the elastic piece structure that A type USB connector male connectors (plug Plug) are fixed on housing also have it is very big
Structural void, international industrial standard waterproofing grade can not be used safely in the adverse circumstances of high humility in below IPX7,
It is used for a long time in general wet environment there is also very big security risk, moisture can pass through these assembly clearances and knot completely
Structure gap enters electronic equipment internal, and then makes safe distance reduction between electronic component.Cause dysfunction or short-circuit nothing
Method uses, and even results in and burns out circuit board, electric shock, on fire, explosion, jeopardizes the life security of people.

One kind in methyl acrylate (Polymethyl methacrylate, initialism PMMA, be commonly called as organic glass).
Preferably, the upper waterproof case material and the lower waterproof case material are polyamide PA.
The fixed feet of the housing is 2~4 fixed feets.
The manufacturing method of this waterproof A types USB connector female seat includes the manufacturing method of A type USB connector female seats, institute
It states A type USB connector female seats to be made of four connection pins, glue core and housing equipped with fixed feet, is first noting the glue core
It is moulded into after type and is connected pin assembling with described four, then A type USB connector female seats are assembled into the housing.
The characteristics of manufacturing method of this waterproof A types USB connector female seat is：
There are following steps successively：
1) using waterproof case and lower waterproof case in the difference injection molding of identical material, the upper waterproof case and described
The size of lower waterproof case meets usb protocol regulation；
2) through hole by the installation corresponding with the lower waterproof case of four of A types USB connector female seat connection pins is adopted
It is assembled with interference fit, waterproof sealing structure is formed in through hole；
3) by the socket of the fixed feet of the housing of A types USB connector female seat installation corresponding with the lower waterproof case
It is assembled using interference fit, waterproof sealing structure is formed in spigot；
4) it is using ultrasonic bonding that the upper waterproof case and the lower waterproof case is welded, it is formed totally-enclosed anti-
Waterproof A type USB connector female seats are made in water shell.
The advantageous effect of the utility model compared with prior art is：
The utility model is welded by upper waterproof case and lower waterproof case using ultrasonic bonding, is formed totally-enclosed anti-
Water shell effectively avoids moisture from entering electronic equipment internal by unsealing A type USB connector female seats, is obtained with lower cost
