Electrical Connector Assembly

【Technical field】

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

【Background technique】

The electrical connector assembly related to the present invention is disclosed in Chinese Patent Publication No. 2629252 and No. 2609213, which includes an insulating body, a conductive terminal accommodated in the insulating body, and a pick-and-place plate covered on the insulating body. The insulating body is roughly rectangular, and it is provided with a base body and side walls extending from the periphery of the base body. There are a number of terminal receiving holes in the base body, and the conductive terminals are accommodated in the terminal receiving holes, and are electrically connected to the chip module through the contact parts of the conductive terminals. , connect to the circuit board through the solder ball at the bottom of the conductive terminal, so as to realize the electrical connection between the chip module and the circuit board.

The pick-and-place plate is coated on the upper surface of the insulating body, and it has two main functions. First, it provides a suction plane for the pick-and-place device to move the electrical connector; second, because it covers the upper surface of the insulating body , can prevent dust or other external pollutants from entering the electrical connector, thereby contaminating the contact portion where the conductive terminal contacts the chip module. However, a pick-and-place board 10 as shown in FIG. Used to clamp with the insulating body, it includes an elastic part 1030 extending from the main body 101, and a clamping part 1031 bent and extended vertically from the end of the elastic part 1030. The clamping part 1031 is provided with a convex part 1032 toward the main body 101. The protrusion 1032 is used for interlocking with the insulating body. When the cantilever 103 is improperly clamped with the insulating body, the cantilever 103 is easily broken due to excessive deformation.

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 with a pick-and-place board, especially an electrical connector assembly that can prevent the cantilever of the pick-and-place board from breaking.

In order to solve the above technical problems, the utility model provides an electrical connector assembly, which can be used to electrically connect the chip module to the printed circuit board. The pick-and-place plate on the pick-and-place plate is provided with a pick-up part on the opposite side of the pick-and-place plate. Cantilever arms are arranged on both sides of the pick-up part. The cantilever extends toward the pick-up part. Deformed stop.

Compared with the prior art, the utility model has the following advantages: when the pick-and-place plate is used improperly, the cantilever will be excessively deformed downward, and the stopper at the end of the cantilever can interfere with the pick-up portion on the pick-and-place plate , to prevent the cantilever from breaking due to excessive deformation.

【Detailed ways】

Please refer to Figures 2 to 4, which are the first embodiment of the electrical connector assembly of the present invention, which is used to electrically connect the circuit board (not shown) and the chip module (not shown), which includes: The connector 5 and the pick-and-place plate 6 buckled on the electrical connector 5 .

The electrical connector 5 includes an insulating body 51 and a plurality of conductive terminals (not shown) accommodated in the insulating body 51. The insulating body 51 is roughly rectangular in shape, and is provided with an inwardly recessed recessed area 511, in which the recessed area 511 There are a number of terminal receiving grooves 512 arranged in a matrix, and a number of conductive terminals are accommodated in the terminal receiving grooves 512. The upper part of the conductive terminal is used to contact the chip module for electrical conduction, and the lower part is welded to the circuit board. Realize the electrical conduction between the chip module and the circuit board. A protruding post 5110 is provided on the inner wall of the recessed area 511, which can be used as a fool-proof device. An opposite groove 5112 is formed on the outer wall of the insulating body 51 .

The pick-and-place plate 6 is interlocked with the outside of the insulating body 51, and it is provided with a plate-shaped base body 61. The base body 61 is provided with a bottom surface 611 and a smooth upper surface 612 opposite to the bottom surface 611. The bottom surface 611 extends toward the insulating body 51. There are several ribs 6110 for positioning, and the smooth upper surface 612 is used for cooperating with a vacuum suction device (not shown) to remove the electrical connector assembly. The opposite sides of the base body 61 are extended with pick-up parts 613, and there are notches (not labeled) on both sides of the pick-up part 613, and a cantilever 614 corresponding to the pick-up part 613 extends in the notch, and the cantilever 614 includes a pick-and-place The extension arm 6141 extending parallel to the side of the plate 6, the end of the extension arm 6141 is provided with a clamping portion 6142 extending vertically downward, and the clamping portion 6142 is provided with a protrusion (not labeled) protruding into the pick-and-place plate 6 , the pick-and-place plate 6 is clamped in the groove 5112 of the insulating body 51 through the protrusion. A stop portion 6143 is provided at the end of the cantilever 614 in the direction in which the cantilever extends, so as to prevent the cantilever 614 from breaking when it is used improperly.

When the pick-and-place plate 6 is used to buckle on the insulating body 51, excessive downward or upward deformation as shown in Figures 5 and 6 may occur. The side ends of the cantilever 613 interfere with each other to prevent the cantilever 614 from being excessively deformed, so that the problem that the cantilever 614 continues to be excessively deformed and breaks can be avoided.

Referring to shown in Figure 7, it is the second embodiment of the present utility model, which is basically the same as the first embodiment, a cantilever 614' is provided on the pick-and-place plate 6', the difference is that the end of the cantilever 614' is provided with an upward The extended stop portion 6143' can still prevent the cantilever 614' from breaking.

The above are only preferred implementations of the utility model, and any improvements made on the basis of this implementation should not deviate from the technical solution of the utility model.
