Electrical connection assembly

Abstract

The utility model provides a kind of electric connection assembly, including a connector and a plug-in board inserted in connector, the connector includes a plurality of terminals of a insulating body and receiving in insulating body, the insulating body is equipped with a top wall, a bottom wall, a pair of end walls and between top wall and bottom wall a plug-in slot, the plug-in board is equipped with a board, in the plug-in part of the board front end edge, a pair of installation parts is outwardly protruded from the two side edges of plug-in part, the plug-in part is inserted in the plug-in slot, the installation part is located outside the insulating body and is fixed on a circuit board.Compared with prior art, the utility model is fixed by optimizing the fixing mode of plug-in board, when plug-in board is plugged in place, only the installation part can be used to fix plug-in board on circuit board, eliminates the installation and turnover operation of the existing technology in transfer pressure plate, can realize automatic assembly, greatly simplifies assembly procedure and improves production efficiency, and the setting of installation part can provide stable and reliable holding force for plug-in board, so that it is not easy to be loosened with connector and cause poor contact.

Claims

1. An electrical connection assembly, comprising an electrical connector and a plug plate inserted into the electrical connector, the electrical connector comprising an insulating body and a plurality of terminals housed within the insulating body, the insulating body having a top wall, a bottom wall, a pair of end walls, and a plug groove between the top wall and the bottom wall, characterized in that: The plug-in board has a plate body, a plug-in portion located at the front edge of the plate body, and a pair of mounting portions protruding outward from the two side edges of the plug-in portion. The plug-in portion is inserted into the plug-in slot, and the mounting portions are located outside the insulating body and fixed to a circuit board.

2. An electrical connection assembly as claimed in claim 1, characterised in that: The mounting portion protrudes outward beyond the end wall of the insulating body, and a mounting hole is provided on the mounting portion to accommodate a fixing member.

3. An electrical connection assembly as claimed in claim 2, wherein: The thickness of the plug portion is greater than the thickness of the plate body.

4. An electrical connection assembly as claimed in claim 3, wherein: The length of the top wall in the front-to-back direction is shorter than that of the bottom wall, thereby forming a recessed notch between the front side of the top wall and a pair of end walls.

5. An electrical connection assembly as claimed in claim 4, wherein: The outer wall surfaces of the pair of end walls are provided with a pair of outwardly protruding buckle protrusions, and the outer wall surface of the top wall is provided with a plurality of upwardly protruding ridges, which are distributed along the length direction of the top wall.

6. An electrical connection assembly as claimed in claim 5, wherein: The electrical connector also includes a metal housing, which has a top cover and a pair of side covers. The top cover covers the top wall of the insulating body and has a groove for engaging with the protruding strip. The side covers have openings for engaging with the snap-fit ​​protrusion.

7. An electrical connection assembly as claimed in claim 6, wherein: The terminal has a top arm, a bottom arm, a fixed arm connecting the top arm and the bottom arm, and a welding arm extending from the bottom of the fixed arm to the rear of the insulating body. The top arm and the bottom arm extend horizontally in the front-rear direction, and the extension length of the top arm is less than the extension length of the bottom arm.

8. An electrical connection assembly as claimed in claim 7, wherein: The bottom arm is housed within the bottom wall, and the end of the bottom arm protrudes upward from the bottom wall to press against the plug plate.

9. An electrical connection assembly as claimed in claim 8, wherein: The bottom edge of the side cover plate is also provided with a pair of downward protruding pins, which are used to fix the plate to the circuit board.

10. An electrical connection assembly as claimed in any one of claims 1 to 9, wherein: The plug-in board is an FPC flexible board or a printed circuit board.
