Connector socket bush hole structure
Technical Field
The invention relates to a connector socket bush hole structure, and belongs to the technical field of automobile accessory connection.
Background
In order to prevent the socket from loosening during the operation of the automobile and when the plug is plugged in and pulled out, the connector socket needs to be fixed on the host interface of the automobile variable box. In the prior art, a bushing is generally disposed on the connector socket, and a screw is locked through a bushing hole. Because the height of bush is the same with connector socket height, can cause the bush surface to have the plastic to remain when moulding plastics, can produce the plastics piece during the lock screw, even cause the damaged phenomenon of plastics fracture to appear.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and provides a connector socket bushing hole structure which can ensure that no plastic exists on the surface of a bushing after injection molding of a product and the phenomenon of cracking and damage of a plastic surface can not occur.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a connector socket bush hole structure, includes the connector socket, be provided with two flat connection portion of an organic whole connection on the connector socket, two flat connection portion along connector socket left and right sides symmetry sets up, the installation is fixed with the bush in the flat connection portion, the height of bush upper end is higher than flat connection portion's upper surface, the lower extreme of bush highly is less than flat connection portion's lower surface, the screw passes the bush, the lower extreme screw in of screw is to on the car variable case.
The screw is a hexagon socket head screw.
The screw is made of stainless steel.
The connector socket and the flat connecting part are made of plastic.
The height of the upper end of the bushing is 0.15mm higher than the upper surface of the flat connecting part, and the height of the lower end of the bushing is 0.15mm lower than the lower surface of the flat connecting part.
The height of the bushing is 12 mm.
The invention has the beneficial effects that: according to the connector socket lining hole structure provided by the invention, during injection molding, the lining is higher than the surface of the plastic surface of the connector socket, so that plastic residues on the surface of the lining can not be caused, plastic chips can not be generated during screw locking, and the cleanness of an assembled product can be ensured to meet the requirement. In addition, after the screw is locked in the assembling process, the screw head is in surface contact with the lining when being completely locked to the bottom, and is not in direct contact with the plastic surface, so that the cracking and damage phenomena of the plastic surface can not occur, and the 100% meeting requirements of product assembly can be ensured.

Detailed Description
The present invention is further described with reference to the accompanying drawings, and the following examples are only for clearly illustrating the technical solutions of the present invention, and should not be taken as limiting the scope of the present invention.
As shown in fig. 1 to 3, the present invention discloses a connector socket bushing hole structure, which includes a connector socket 1, wherein two flat connection portions 4 integrally connected to each other are disposed on the connector socket 1, and the two flat connection portions 4 are symmetrically disposed along left and right sides of the connector socket 1. The flat connecting part 4 is internally provided and fixed with a bushing 3, the upper end of the bushing 3 is higher than the upper surface of the flat connecting part 4, the lower end of the bushing 3 is lower than the lower surface of the flat connecting part 4, the screw 2 penetrates through the bushing 3, and the lower end of the screw 2 is screwed into the automobile variable box.
Preferably, the screw 2 is a socket head screw.
Preferably, the material of the screw 2 is stainless steel.
Preferably, the connector socket 1 and the flat connection portion 4 are made of plastic.
Preferably, the height of the upper end of the bush 3 is 0.15mm higher than the upper surface of the flat connection part 4, and the height of the lower end of the bush 3 is 0.15mm lower than the lower surface of the flat connection part 4.
Preferably, the height of the bush 3 is 12 mm.
According to the connector socket bushing hole structure, the heights of the two ends of the bushing are increased, so that the bushing is 0.15mm higher than the plastic surface, the bottom of the screw head cannot directly contact the surface of the plastic surface after a screw is assembled, the surface of the bushing cannot be provided with plastic after a product is subjected to injection molding, and the cleanliness of the assembled product is ensured. In addition, after the screw is locked in the assembling process, the screw head is in surface contact with the lining when being completely locked to the bottom, and is not in direct contact with the plastic surface, so that the cracking and damage phenomena of the plastic surface can not occur, and the 100% meeting requirements of product assembly can be ensured.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
