Detailed Description

The technical solutions in the implementation of the present invention will be clear from the following description and accompanying drawings, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 6, an electric vehicle controller connection line fixing structure provided by an embodiment of the present invention includes a housing 1 of a controller, where the housing 1 is provided with a front end cover 11 and a rear end cover 12, the front end cover 11 and the rear end cover 12 are fixedly connected to the housing 1 through screws, the front end cover 11 is provided with a wire outlet 111, the wire outlet 111 is provided with a line fixing device 2, the line fixing device 2 includes an outer shield 21 and an inner shield 24, the outer shield 21 and the inner shield 24 are respectively disposed on the front end cover 11 far from the housing 1 and the inner shield 24 is disposed on the front end cover 11 facing the housing 1, a line limiting core 22 passing through the wire outlet 111 is disposed between the outer shield 21 and the inner shield 24, four bolt holes 112 are disposed on the front end cover 11 near the wire outlet 111, the outer shield 21 and the inner shield 24 are both provided with wire outlet holes 211, and corresponding bolt holes 112 are also disposed on the outer shield 21 and the inner shield 24, the circuit limiting core 22 is provided with a plurality of circuit mounting holes 221 for clamping connecting wires of the controller, and the outer blocking cover 21 and the inner blocking cover 24 are locked on the front end cover 11 through bolts 23 and clamp the circuit limiting core 22 in the middle. Through setting up outer fender lid 21, interior fender lid 24 and the spacing core 22 of circuit, the connecting wire can be worn to insert fixedly in the circuit mounting hole 221 on the spacing core 22 of circuit, and outer fender lid 21 and interior fender lid 24 press from both sides the spacing core 22 of tight circuit and fix on front end housing 11, realize the rigidity of connecting wire, prevent that the connecting wire from rocking the condition emergence that leads to electric vehicle controller internal connection to damage in outlet 111 department, guarantee electric vehicle controller's normal.
