For ease of description, when introducing the electrical connector 100 below, the docking direction of the electrical connector 100 will be regarded as the front-to-back direction, a direction perpendicular to the front-to-back direction will be regarded as the lateral direction, and another direction perpendicular to the lateral direction will be regarded as the up-down direction.

[0027] Please refer to Figures 1 to 3 and Figure 8 、 Figure 9 As shown, the insulating body 1 extends in the transverse direction and has a plurality of terminal slots 11 formed therethrough in the front-to-back direction and a locking arm 12 located on the upper side thereof for locking with a docking connector (not shown). The locking arm 12 is provided with at least one locking portion 121 located on the upper side thereof. The locking arm 12 is elastic so that the free end located at the rear end thereof can move downward under the action of an external force, thereby realizing locking and unlocking with the docking connector (not shown).

[0028] In addition, the insulating body 1 is further provided with an installation space 13 formed by being recessed forward from its rear end surface and a plurality of snap grooves 14 connected to the installation space 13. In this embodiment, the snap grooves 14 are distributed on the upper, lower, left and right sides of the installation space 13.

The conductive terminal 2 also has a connecting section 24 connecting the holding section 21 and the contact section 22. The connecting section 24 is connected to the contact section 22 only on one side in the up and down direction or the lateral direction, thereby reducing the plugging and unplugging force of the electrical connector 100 and effectively improving the vibration level.

[0030] Specifically, in this embodiment, the holding section 21 includes a first bottom wall 211 and a pair of holding walls 212 oppositely disposed on both sides of the first bottom wall 211, the contact section 22 includes a second bottom wall 221 and a pair of side walls 223 oppositely disposed on both sides of the second bottom wall 221, and the connecting section 24 connects the first bottom wall 211 and the second bottom wall 221.

As shown in the illustrated embodiment, the connecting section 24 is connected to one side of the contact section 22 in the vertical direction; of course, in other embodiments of the present invention, the connecting section 24 can also be connected to one side of the contact section 22 in the horizontal direction, that is, the connecting section 24 is connected to one of the side walls 223.

[0031] Each retaining wall 212 is aligned with the side wall 223 on the same side thereof in the front-to-back direction. Each retaining wall 212 is provided with a slot 2121 extending transversely therethrough.

[0036] Furthermore, in the embodiment of the present invention, the conductive terminals 2 include first terminals 2a arranged in one row and second terminals 2b arranged in another row. The first terminals 2a and second terminals 2b are offset in the transverse direction. A gap is formed in the middle of the first terminal 2a in the transverse direction to divide it into two parts located on either side of the locking arm 12, thereby leaving space for the locking arm 12 in the middle of the insulating body 1.
