The utility model discloses a screw pressure is on the sleeve, and the sleeve presses PCB, then fixed with the plastic main part, and this kind of mode can make PCB move down to reduce the whole height of product, and reduce cost.

Description

PCB fixing structure in charging socket

Technical Field

The utility model relates to a socket technical field especially relates to a PCB board fixed knot in socket charges constructs.

Background

A direct-current charging socket for a new energy electric vehicle belongs to an electric connection type wire harness product, is installed on the electric vehicle according to the requirements of a vehicle factory, and has one of the requirements on the charging socket that the size is as small as possible so as to reduce the occupied space. The circuit board is arranged in the charging socket, the fixing screw holes are formed in the insulating base in the current charging socket and matched with the fixing holes in the circuit board, the length of the fixing screw holes in the general charging socket is not less than 8mm, otherwise, the locking force of screws is insufficient, and by adopting the screw locking structure, a large enough space is reserved between the insulating base and the rear cover to accommodate devices on the circuit board, so that the product space is large, and the product cost is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, a PCB fixing structure in a charging socket is provided.

The purpose of the utility model is realized with the following mode:

the utility model provides a PCB board fixed knot in socket that charges constructs, is including setting up fixed screw 3, PCB board 2 on socket shell insulating seat 1, still includes sleeve 5, the upper end of PCB board 2 is fixed in fixed screw 3 through sleeve 5 to push down sleeve 5 through set screw 4 and fix it on insulating seat 1.

The length of the sleeve 5 is less than that of the fixing screw hole 3.

The utility model has the advantages that: compared with the prior art, the utility model discloses a screw pressure is on the sleeve, and the sleeve presses PCB, then fixed with the plastic main part, and this kind of mode can make PCB move down to reduce the whole height of product, and reduce cost.
