Understandably, the recessed grooves 18 are located on the bottom wall of the surface groove, and the recessed grooves 18 can play a role in heat dissipation, improving the heat dissipation efficiency of the electrical connector; in addition, the surface groove can prevent the space between two adjacent conductive terminals 3 from being entirely solid insulating housing 1, making it less likely for the current between two adjacent conductive terminals 3 to break down the insulating housing 1, thus improving the safety of the electrical connector.

[0045] In one embodiment, such as Figure 1 As shown, the insulating housing 1 is also provided with a mounting wall 19.
