However, the above-mentioned electrical connector holds and positions the chip module in the side wall 102 of the elastic arm 103 and the fixing bump 104 against the side of the chip module. However, due to insufficient stability, the chip module may be disconnected from the electrical connector. A case of detachment within the connector.

In view of this, it is necessary to improve the above electrical connector to overcome the above drawbacks.

【Content of utility model】

The purpose of the utility model is to provide a chip module combination, especially a chip module combination that can stably hold the chip module and prevent it from being separated from the electrical connector.

The purpose of this utility model is achieved as follows: a chip module combination, including a chip module and an electrical connector that can connect the chip module to a circuit board, the electrical connector includes an insulating body that accommodates several conductive terminals, and the insulating body is designed There is a flat bottom wall and a side wall extending vertically upward along the bottom wall, and the side wall is further provided with a first side wall, a third side wall opposite to the first side wall, and a third side wall adjacent to the first side wall. The second side wall and the fourth side wall, the first side wall and the third side wall are provided with an elastic arm, the elastic arm is provided with an abutment portion, the chip module is provided with an edge area close to the side wall, and the edge area corresponds to the abutment portion A groove is provided, and a gap portion is provided in the groove, wherein, after the chip module is mounted on the insulating body, the abutting portion abuts against the gap portion so as to limit the chip module in the insulating body.

Compared with the prior art, the utility model has the following advantages: after the chip module of the utility model is installed on the electrical connector, the abutment part of the elastic arm is against the gap part of the edge area of the chip module, therefore, it can effectively Prevent the chip module from detaching from the insulating body.
