Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model discloses the technical scheme who specifically implements is:

as shown in fig. 1 and 2, a vehicle-mounted wire harness includes a wire harness body, and a fixing component sleeved on the wire harness body;

the wiring harness comprises a wiring harness body and is characterized in that wiring terminals 1 are respectively arranged at two ends of the wiring harness body, and the wiring harness body comprises a plurality of connecting wires 2 which are arranged side by side;

the fixing assembly comprises an upper plate body 3, a lower plate body 4 and a middle plate body 5 positioned between the upper plate body 3 and the lower plate body 4, a plurality of buffer springs 6 are connected between the upper plate body 3 and the middle plate body 5, a plurality of first clamping grooves 51 are arranged at the bottom of the middle plate body 5, the top of the lower plate body 4 is provided with a plurality of second clamping grooves 41 which correspond to the first clamping grooves 51 one by one, the plurality of first clamping grooves 51 and the plurality of second clamping grooves 41 form a plurality of clamping passages therebetween, the connecting wires 2 are respectively arranged in the clamping channels, the two ends of the upper plate body 3 are respectively provided with a countersunk through hole 31, two threaded holes 42 corresponding to the countersunk head through holes 31 one to one are formed in the lower plate body 4, clamping bolts 7 are respectively arranged in the two countersunk head through holes 31, and the lower ends of the clamping bolts 7 penetrate through the countersunk head through holes 31 to be connected with the corresponding threaded holes 42.
