The utility model provides a USB female socket connector mainly includes body 1, preceding shell 2 and backshell 3 etc..

It should be noted that the body 1 is a main structure of the USB female connector, and the specific structure of the body 1 can refer to the structure of the body 1 of the conventional USB female connector in the prior art, which is not described herein again.

It can be understood that the body 1 is provided with the terminal 5, and during assembly, the terminal 5 is firstly installed on the body 1 to form a semi-finished product with the body 1, and then the front shell 2 and the rear shell 3 are respectively installed on the body 1.

Specifically, the front shell 2 and the rear shell 3 are respectively fixedly connected with the body 1, and preferably, the front shell 2 and the rear shell 3 are both fixed to the body 1 in a clamping manner. For example, the body 1 is provided with a first buckle and a second buckle, the front shell 2 is provided with a first clamping groove for clamping and fixing with the first buckle, the rear shell 3 is provided with a second clamping groove for clamping and fixing with the second buckle, and the fixed connection between the front shell 2 and the body 1 is realized through the clamping connection between the first buckle and the first clamping groove; the fixed connection of the rear shell 3 and the body 1 is realized through the clamping connection of the second buckle and the second clamping groove.

It should be noted that the utility model discloses a focus lies in, is equipped with elastic component 4 between preceding shell 2 and the backshell 3, elastic component 4 is used for respectively with preceding shell 2 and backshell 3 in close contact with to can stabilize the circular telegram all the time between preceding shell 2 and the backshell 3.

That is to say, the utility model discloses a gap between 2 and the backshell 3 of casing before the elastic component 4 compensaties the assembly, make preceding casing 2 and backshell 3 can realize the circular telegram between the two through elastic component 4 to make and have stable circuit transmission effect between preceding casing 2 and the backshell 3, and then make backshell 3 can put through the GND of PCB board via the leg 21 of preceding casing 2, make the whole shell of USB female socket connector (preceding casing 2 and backshell 3) can both put through the GND of PCB board, realize the electromagnetic shield function of USB female socket connector.

It can be understood that, because elastic component 4 has certain elasticity, under the extrusion force effect, elastic deformation can take place, consequently, preceding shell 2 and backshell 3 all with body 1 fixed connection back, elastic component 4 can come the deformation volume of automatically regulated self according to the gap size between preceding shell 2 and the backshell 3 to avoid interfering the installation of preceding shell 2 and backshell 3.

It can be seen that the utility model discloses only set up elastic component 4 between preceding shell 2 and backshell 3, compensate the gap between preceding shell 2 and the backshell 3, whole outside profile after body 1, preceding shell 2 and the assembly of backshell 3 can remain unchanged to make under the condition that the client does not make any modification to the layout of PCB board, satisfy the required electromagnetic shield function of customer.

It should be noted that the present invention does not limit the specific arrangement manner of the elastic member 4, for example, the elastic member 4 may be disposed at the position where the body 1 is butted with the front shell 2 and the rear shell 3, so that the elastic member 4 is directly clamped between the front shell 2 and the rear shell 3.
