The terminal 22 generally includes a conductive piece 221 and a screw 222, wherein a conductive head of the wire is placed on the conductive piece 221 and the wire is pressed and fixed by the screw 222. The wire connecting terminal 22 of the present embodiment includes two opposite conductive sheets 221, and the screw 222 is fixed on one conductive sheet 221 and can be close to or away from the other conductive sheet 221 for connection, so that when the wire is fixed, a tool is used to screw the screw 222 to drive one conductive sheet 221 to be close to the other conductive sheet 221 so as to compress the wire, thereby achieving electrical connection. The structure enables the electric connection to be stable and facilitates the connection of the wires. The number of the terminals 22 is set according to actual conditions, and in order to maintain the regularity of the wiring, the plurality of terminals 22 are distributed in an array form, thereby further facilitating the connection of the wires. In order to prevent the interference between two adjacent connection terminals 22, a plurality of longitudinal partition plates arranged at equal intervals are convexly arranged on the base 21, so that an independent accommodating space is provided for each connection terminal 22, and the safety of the connection wire of the connection terminal base 2 is ensured.

The wire harness structure may be a single integral body fixed to the base 21 in a detachable connection manner, or may be integrally formed with the base 21. The bunch structure of this embodiment is as an organic whole structure with base 21, then can improve bunch structure's stability, guarantees the stability of pre-fixed wire. Specifically, the wire harness structure includes a plurality of engaging members 23, each engaging member 23 is disposed corresponding to one of the connecting terminals 22, and the engaging members 23 are made of plastic or resin, so as to be integrally formed with the base 21. When an external wire enters the electronic control box 10 through the wire inlet hole, a wire is correspondingly pre-fixed in the clamping groove 23a of the clamping piece 23, so that the size of the accommodating space of the clamping groove 23a should be matched with the diameter of the wire, so as to realize stable fixation of the wire.

The wire holder 2 comprises a plurality of wiring terminals 22 and a wire harness structure corresponding to the wiring terminals 22, wherein the wire harness structure comprises clamping pieces 23 corresponding to the wiring terminals 22 one by one. When each wire is electrically connected to the wiring terminal 22, each wire can be pre-fixed in the clamping groove 23a of each clamping piece 23 to complete the preliminary pre-positioning of the wire, and then the end part of the wire is connected with the wiring terminal 22.

Referring to fig. 3 and fig. 4, the engaging member 23 includes two elastic buckles 231 disposed opposite to each other, and opposite surfaces of the two elastic buckles 231 cooperate to form the engaging groove 23a.

In this embodiment, in order to keep the engaging member 23 capable of fixing the wire firmly, one engaging member 23 includes two elastic buckles 231, the opposite surfaces of the two elastic buckles are matched to form a clamping groove 23a, one of the elastic buckles 231 can elastically deform relative to the other elastic buckle 231, and the distance between the two elastic buckles 231 is smaller than the diameter of the wire, so as to ensure that the wire is always in a clamping state, thereby prolonging the service life of the wire harness structure of the wire holder 2.
