A new energy vehicle thin-pin pin-slot cover buckle anti-bending high-voltage wiring harness layout structure

Abstract

The invention discloses a buckling and bend preventing high-voltage wiring harness layout structure for fine pin needle slots of a new energy vehicle, which structurally comprises a wiring harness collection base, a wiring box, a pin wiring harness slotted plate, a top cover plate, single control node holes, three-phase electric sockets, double-pin cap slots and main power supply sockets. According to the invention, the wiring harness collection base is applied to be matched with the pin wiring harness slotted plate, and pin needle wiring harnesses are inserted into I-shaped slot cylinders ina wiring harness slot cross frame and connected to a main cable in the wiring box by workers, so that the wiring harness collection base is conducted to achieve the effects of wiring, current collection and transmission. A needle tube of the wiring harness buckles and wraps from the head and tail ends through an arc plate cross-pulling ring and a covering and buckling corrugated plate, thereby forming an effect of pressing and protecting the needle tube body. The wire tube end at the needle tail part is taken in, thereby forming ductile pull-up deformation of the end for being matched with a rubber wire tube shell, reducing the stress of the needle head, and forming an attaching operation for preventing the slippage of a seal ring for the wire end. The stress-proof protection inner concavearc surface is strengthened in the middle section so as to achieve the effects of end quality protection of the wiring harnesses and accurate control of the new energy vehicles.

Description

technical field [0001] The invention relates to an arrangement structure of a high-voltage wire harness for anti-bending of a thin-pin needle slot cover buckle for a new energy vehicle, belonging to the field of high-voltage wire harness equipment for a new energy vehicle. Background technique [0002] The integrated wiring harness box of the new energy vehicle is the transfer station between the control board and the engine in the integrated vehicle. The high-voltage wiring harness is the transformer wire adapted to the output of the engine, which is convenient for undertaking the transfer of the voltage circuit and the change of the value, so that the new energy vehicle The driving performance is stronger, and the shortcomings to be optimized in the current technology are: [0003] Whether the plug-in terminal of the wire harness is a round slot or a square slot, multiple pins are welded inside to connect the branch wire tubes to form a centralized plug-in power supply mod...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the existing technology, the purpose of the present invention is to provide a new energy vehicle thin-pin pin slot cover buckle anti-bending high-voltage wire harness arrangement structure to solve the problem of whether the plug-in terminal of the wire harness is round or square. Internally, multiple pins are welded to connect branch wire tubes to form a centralized plug-in power-on mode, and the pins are often slender in diameter, and their own bending resistance is insufficient and there is a certain distance between the two ends of the force, which will cause plugging and lifting. During the process of threading, the pulling force of the needle tail connection and the hinge force of the needle inserting the wire form an intermediate extrusion resistance stress, which causes the pins to generally fold in the middle. The unevenness of the tube needles cannot achieve the flushing effect of insertion and insertion, and some pins in the wiring harness will not be able to conduct, resulting in the failure of the control of the local panel buttons of the new energy vehicle
