[0018] Reference Figures 1 to 4 As shown, the utility model provides an electric vehicle power control harness that is easy to connect, including: a harness connector 1, a power control wire 2 and a wiring socket 3. The side end of the power control wire 2 is connected to the wiring socket 3 through the harness connector 1.

[0019] An extension plate 11 is provided on the right end face of the wiring harness connector 1, and an elastic band 12 is connected to the right end of the extension plate 11. The elastic band 12 is fastened to the right side of the wiring socket 3 through a Velcro 13. An anti-pressure plate 4 is clamped in the groove of the extension plate 11, and a buffer spring 41 is connected to the side of the anti-pressure plate 4. Protective side plates 42 are fixed to the front and rear sides of the anti-pressure plate 4. The middle part of the inner side surface of the anti-pressure plate 4 contacts the upper and lower surfaces of the wiring socket 3 through the arc-shaped elastic block 5.

[0020] When connecting the power control wiring harness of the electric vehicle, first connect the corresponding wiring socket 3 with the wiring harness connector 1 of the power control wire 2, so that the wiring socket 3 fits into the anti-slip strip connected to one end of the buffer spring 41, and at the same time, the arc surface of the arc-shaped elastic block 5 on the inner side of the anti-pressure plate 4 contacts the wiring socket 3. After plugging in place, pull the elastic band 12 at the side end of the extension plate 11, so that the upper and lower sets of elastic bands 12 are fastened to the right side of the wiring socket 3 through the Velcro 13, and tighten the wiring socket 3 and the wiring harness connector 1 to complete the connection of the power control wiring harness of the electric vehicle.

[0021] In this embodiment, the right side of the wiring harness connector 1 is connected to the socket of the wiring receptacle 3 via a plug 14, with extension plates 11 symmetrically located at the upper and lower ends of the plug 14. A transmission wire 31 is connected to the right end of the wiring receptacle 3, while a power control wire 2 is connected to the left end of the wiring harness connector 1; this power control wire 2 is electrically connected to the electric vehicle controller.

[0022] As a preferred embodiment, the transmission wire 31 facilitates connecting the power control wire 2 with multiple circuits of the electric vehicle, so that the power control wire 2 transmits power to multiple circuits to ensure the normal driving of the electric vehicle.

[0023] In this embodiment, rubber pads 43 are bonded to the outer sides of the protective side panels 42, which are attached to the front and rear sides of the wiring socket 3. Ventilation slots 51 are defined on the lower curved surface of the curved elastic block 5, and buffer springs 41 are located on both the front and rear sides of the curved elastic block 5. The other ends of the buffer springs 41 are pressed against the surface of the wiring socket 3 via anti-slip strips.

[0024] As a preferred embodiment, the pressure plate 4 and protective side panels 42 are U-shaped and clipped onto the outside of the wiring socket 3. This effectively cushions and supports vibration or impact forces applied to the electric vehicle's power control harness connector, preventing damage and failure that could affect power transmission. The buffer spring 41 uses its elasticity to push the pressure plate 4 outward to resist external impact forces. The arc-shaped elastic block 5 separates the pressure plate 4 from the wiring socket 3, providing vibration isolation and buffering.

[0025] In this embodiment, the anti-pressure plate 4 , the buffer spring 41 , the protective side plate 42 and the arc-shaped elastic block 5 constitute the anti-collision structure of the wiring harness connector 1 .

[0026] As a preferred embodiment, the anti-collision structure of the wiring harness connector 1 facilitates preventing damage and breakage of the power control harness connection end, extending the durability of the electric vehicle power control harness, and improving the safety of the electric vehicle power control harness quick-connect end.
