Detailed Description
Referring to fig. 1, the present invention provides a circuit board connecting structure.
The circuit board connecting structure comprises a polymer bottom shell 1 and a circuit board 2.
A circuit board mounting region 11 for mounting the circuit board 2 is formed on one side of the polymer bottom case 1.
The board mounting area 11 has a size larger than that of the board 2 so as to mount the board 2. The edge of the circuit board mounting area 11 is provided with a raised enclosure 12, and the enclosure 12 encloses a glue injection groove for injecting glue.
Since the size of the circuit board mounting area 11 is larger than that of the circuit board, the circuit board 2 can be mounted in the glue injection groove enclosed by the rail.
In order to ensure the smooth proceeding of the glue injection operation, the height of the enclosure 12 is not less than the thickness of the circuit board.
The circuit board mounting area 11 is further provided with at least one positioning column 13 perpendicular to the polymer bottom case, and correspondingly, the corresponding position of the circuit board 2 is also provided with a positioning hole matched with the positioning column 13.
The positioning column 13 is matched with the positioning hole on the circuit board 2, so that the circuit board 2 can be quickly installed at the designated position, and other tools are not needed in the installation process.
Further, the number of the positioning columns 13 is at least two, so that the efficiency of positioning and mounting the circuit board 2 is improved in a multi-point positioning manner.
Furthermore, the positioning columns 13 are distributed as far as possible, so as to further improve the effect of positioning and installation.
And a fixing structure for fixing the circuit board is also arranged at the edge of the preset mounting position of the circuit board in the circuit board mounting area. In this embodiment, the fixing structure is a hook-type fastener 14, which fastens the edge of the circuit board after the circuit board is mounted to the fixing position.
In order to ensure the fixing effect, the number of the hook-type buckles 14 is at least two, and the hook-type buckles are arranged at different edges of the preset installation position of the circuit board as far as possible so as to further improve the fixing effect.
The circuit board is positioned and installed in the circuit board installation area in a mode that the positioning holes are sleeved with the positioning columns, is arranged in a mode of being tightly attached to the polymer bottom shell, and is further fixed through the hook-shaped buckles 14.
The utility model provides a circuit board connection structure is when using, and the assembly personnel only need with the reference column of the locating hole alignment polymer drain pan of circuit board to with the circuit board push away establish to hug closely the position of polymer drain pan, and with the border of circuit board with the hook type buckle fixed can. And after the fixation is finished, the subsequent steps of injecting glue and the like can be carried out.
The utility model provides a circuit board connection structure makes the fast assembly that the assembly personnel need not the instrument and can realize polymer drain pan and circuit board, has also practiced thrift the material consumption in the installation simultaneously, has improved packaging efficiency and very big reduction in cost.
The present invention has been described in detail with reference to specific embodiments, and the description of the embodiments is only for the purpose of helping understanding the core idea of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
