As shown in fig. 2, the locking mechanism 20 includes an elastic member 21, a sliding member 22, and at least two locking plates 23, wherein the at least two locking plates 23 lock the same insert 200, such as a first insert, a second insert, or a third insert. For convenience of explanation, in the present embodiment, two opposing lock plates 23 are provided. One end of each lock plate 23 is pivotally connected to the sliding member 22, so that the lock plate 23 can pivot relative to the sliding member 22. As shown in fig. 3, the elastic member 21 is used for providing an elastic force acting on the sliding member 22, so as to pre-tension the sliding member 22, so that the locking plate 23 is in an inclined state relative to the length direction of the insert 200, and under the action of the elastic member 21, the locking plate 23 gives pressure to the insert, thereby achieving the knife edge surface frictional contact locking. The pretensioning direction of the elastic element 21 and the pulling-out direction of the insert are preferably the same. When one of the locking plates 23 fails to be locked, the other locking plates 23 can keep locking, thereby improving the locking reliability of the electrical connector and the connector device 100.

As shown in fig. 2 and 3, the locking plate 23 has a notch 231 for the insertion sheet to pass through, and the locking plate 23 can be disposed in an opposite manner up and down or left and right at substantially the same position of the insertion sheet, so as to save the space occupied by the locking plate 23, and when locking, the locking plate 23 is locked at the same position of the insertion sheet 200. The locking plate 23 may be inclined in opposite directions when locking the insert 200. The cross-section of inserted sheet can be the rectangle, one of them the inserted sheet is used for locking the longer one end of rectangle, another the inserted sheet is used for locking the longer other end of rectangle makes things convenient for in the degree of depth that increases the breach, increases the contact position.

The fixed end 211 is pressed by the housing 11 near the torsion spring body 212, so as to ensure that the torsion spring body 212 is not easy to displace when the torsion spring is twisted, and provide a stable torsion force for the sliding member 22.

Referring to fig. 2, in order to provide a smooth pre-tightening force to enable each of the transmission portions 221 to be evenly stressed and enable each of the locking plates 23 to be capable of sufficiently locking the insertion sheet, the toggling end 213 simultaneously applies a force to the sliding member 22 at different positions corresponding to the transmission portions 221, for example, the stress point of the transmission portion 221 may be located on the central axis of the transmission portion 221. It should be noted that the torsion spring has a first torsion spring body 2121 and a second torsion spring body 2122, the first torsion spring body 2121 and the second torsion spring body 2122 provide an axis, the two parts are connected by the fixed end 211, the first toggle end 2131 extends from the first torsion spring body 2121, the second toggle end 2132 extends from the second torsion spring body 2122, the first toggle end 2131 abuts against the sliding member 22 at a position corresponding to one of the transmission portions 221, and the second toggle end 2132 abuts against the sliding member 22 at another position corresponding to the other one of the transmission portions 221, so that the acting force provided by the torsion spring is more stable.
