Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings.

The embodiment of the application discloses circuit board fixed connection structure, including drain pan and the PCB board 1 of fixing in the drain pan, be provided with button 2, display screen 3 and connection interface 4 on the PCB board 1, still include face-piece 8, be provided with the opening that supplies button 2, display screen 3 and connection interface 4 to wear out on the face-piece 8, PCB board 1 is provided with the contact pin socket structure of mutually supporting relative face-piece 8 one side and face-piece 8 is provided with relative PCB board 1 one side, PCB board 1 and face-piece 8 pass through contact pin socket structure and connect.

Specifically, the above-mentioned grafting structure specifically has following two types:

first, the contact pin socket structure includes a first contact pin 5 arranged on the PCB board 1 and a first socket 6 arranged on the face shell 8, and the first contact pin 5 and the first socket 6 are connected in a matching way.

Second, the contact pin socket structure includes the second socket that sets up on PCB board 1 and sets up the second contact pin on face-piece 8, and second contact pin and second socket cooperation are connected.

When the installation surface shell 8 is specifically installed, the position of the surface shell 8 is aligned with the position of the PCB 1, and then the frontal socket and the contact pin which are installed on the surface shell 8 and the PCB 1 are matched and inserted, so that the surface shell 8 and the PCB 1 are installed in a positioning manner, and at the moment, keys and a liquid crystal screen on the PCB 1 extend out of corresponding holes on the surface shell 8.

In the above-mentioned structure, through the fixed connection of contact pin and socket, owing to the cooperation compactness of contact pin and socket, can make can not take place to rock between PCB board 1 and the face-piece 8 after the assembly is accomplished to can guarantee the installation accuracy, simultaneously, owing to adopt the grafting structure, can realize convenient installation.
