Description

Electrical Connector Assembly

【Technical field】

The utility model relates to an electrical connector assembly, in particular to an electrical connector assembly electrically connecting a circuit board and a chip module.

【Background technique】

Generally, when the electrical connector is soldered on the circuit board, the industry generally adopts a vacuum suction method to transfer the electrical connector so as to effectively position it on the circuit board. The specific method of this vacuum suction method is to assemble a pick-and-place board on the electrical connector, and then move the electrical connector by being adsorbed on the pick-and-place board by a vacuum suction device. However, this method will cause some problems. For example, when the weight of the electrical connector and the suction plate is large, usually greater than 50g, when it is sucked by a vacuum suction device, problems such as weak suction or shaking of the electrical connector will usually occur. .

Therefore, an electrical connector assembly as shown in FIG. 1 emerges at the historic moment. The electrical connector assembly includes an electrical connector 1 and a pick-and-place plate 2. The electrical connector 1 is provided with a metal outer frame on the bottom surface of the insulating body 11. 12. A rectangular frame opening is formed in the center of the insulating body 11 , and the pick-and-place plate 2 is assembled on the electrical connector 1 , and the rectangular opening 20 at the center of the pick-and-place plate 2 corresponds to the frame opening of the insulating body 11 . When removing the electrical connector assembly, first snap the pick-and-place plate 2 onto the metal frame 12 of the electrical connector 1, and then pass an automatic jig such as a manipulator (not shown) through the opening 20 of the pick-and-place plate 2, The electric connector 1 and the pick-and-place board 2 are clamped by the interference between a pair of clamping fingers of the manipulator and the side wall of the opening.

However, there are at least the following defects in this way of picking and placing the electrical connector assembly: improper positioning of the manipulator is prone to occur, that is, the position of the grasping finger of the manipulator placed on the opening 20 may be different each time, thereby causing the electrical connector 1 to be in the circuit. The position placed on the board is inaccurate; secondly, a pair of grasping fingers of the manipulator pass through the opening 20, and the pick-and-place of the electrical connector 1 is realized by the interference between the grasping fingers and the inner side wall of the opening 20, but when the electrical connector 1 and the pick-and-place plate 2 are too heavy, the grip of the pick-and-place plate 2 by the manipulator will not be firm, and the electrical connector 1 will easily slip from the manipulator.

In view of this, it is necessary to provide an improved electrical connector assembly to overcome the above-mentioned defects of the electrical connector assembly.

【Content of utility model】

The technical problem solved by the utility model is to provide an electrical connector assembly, especially an electrical connector assembly with a pick-and-place plate for accurate positioning and firm pick-and-place by a manipulator.

In order to solve the above technical problems, the utility model provides an electrical connector assembly, which is used to electrically connect the chip module to the printed circuit board, which includes an electrical connector and a pick-and-place board that is buckled with the electrical connector. The connector includes an insulating body and a plurality of conductive terminals accommodated in the insulating body. An opening is provided in the center of the pick-and-place plate, and a clamping plate is extended on a side wall of the opening of the pick-and-place plate.

Compared with the prior art, the utility model has the following advantages: the utility model extends a clamping plate from the side wall of the central opening of the pick-and-place plate, and the two opposite sides of the clamping plate can be used as the clamping surfaces of the manipulator, while the other One side can be used as a positioning surface for the positioning of the manipulator, so that the manipulator can be accurately positioned on the pick-and-place board, that is, the position of the manipulator to grab the pick-and-place board is the same every time, so that the electrical connector assembly can be placed on the position of the circuit board every time The same means that it can be accurately placed on the circuit board; secondly, a clamping plate is extended on one side of the central opening of the pick-and-place plate, and the manipulator can surround the surrounding side walls of the clamping plate with multiple mechanical fingers. The pick-and-place of the electrical connector is realized by the interference between the inner side wall of the pick-and-place device and the side wall around the clamping plate. This method increases the interference surface between the pick-and-place device and the manipulator, so the clamping is firmer.
