Description

Technical Field

[0001] The utility model relates to the field of rotational transformer wire harnesses, in particular to a rotational transformer wire harness with an anti-penetration function. Background Art

[0002] The oil-cooled motor of new energy vehicles is the power device that drives the vehicle. In order to determine the operating status of the motor, the motor outputs the resolver signal and temperature signal to the motor controller, which determines the operating status of the motor and implements control according to the established strategy. The cylinder wiring harness inside the oil-cooled motor is the channel for internal and external information transmission. The wiring harness is composed of connectors, wires and other accessories, and the wires are bundled into bundles according to the layout through the outer covering. The wiring harness is the neural network of the car. Its safety and reliability are related to the safety of the passengers and the realization of the vehicle functions. It is a relatively important automotive component.

[0003] When the oil-cooled motor is running, high-temperature and high-density oil and gas will be generated in the sealed shell. High temperature not only affects the service life of the wiring harness, but also causes a pressure difference between the inside and outside of the shell. Poor sealing can cause oil and gas to leak to the outside through the gap between the conductor and the insulation layer of the cylinder connector and the wire. This puts higher requirements on the service life and oil leakage prevention ability of the cylinder wiring harness installed inside the oil-cooled motor. Utility Model Content

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] In this embodiment, refer to Figure 1-Figure 3 A specific implementation of a rotary transformer harness with anti-penetration function includes a cable 1 and connectors respectively arranged at both ends of the cable 1. Two cables 1 are provided, and the two cables 1 are connected through a conductive barrier 2.

[0022] Furthermore, the outer side of the cable 1 is wrapped with a protective tape 5. The protective tape 5 is preferably an acetate cloth tape. The acetate cloth tape is made of acetate fiber cloth as a base material and coated with acrylic flame retardant adhesive. It has excellent high temperature resistance, solvent resistance, aging resistance, insulation, and flame retardant properties, which is beneficial to improving the service life of the cable 1.

[0023] In this embodiment, a sealing rubber plug 6 is sleeved on the cable 1, so that when the resolver harness in this embodiment is installed on the external cylinder body, multi-level sealing of the through-cylinder connector is achieved, which can effectively prevent oil and gas from leaking to the outside through the resolver harness.

[0024] Furthermore, a through hole 601 is provided in the sealing plug 6 for passing the cable 1 , and a plurality of sealing protrusions 602 for interference fit with the cable 1 are evenly provided on the inner wall of the through hole 601 , thereby improving the sealing performance between the cable 1 and the sealing plug 6 and avoiding oil and gas leakage.

[0025] like Figure 4-5 As shown, the conductive isolator 2 staggers the two cables 1 up and down, and the two non-intersecting cables 1 can effectively prevent the oil and gas in the oil cylinder from penetrating outward along the cables 1.

[0026] Furthermore, the outer side of the conductive isolator 2 is wrapped with several layers of heat shrink tubing 3 to improve the waterproof effect here and prevent oil and gas from directly penetrating therefrom.

[0027] The utility model connects two cables 1 through the conductive isolator 2, so that oil and gas cannot leak to the outside through the battery core 1A of the cable 1 and the gap between the battery core 1A and the insulating layer 1B, which significantly improves the anti-oil leakage ability of the resolver wiring harness and ensures the service life of the wiring harness.

[0028] The two cables 1 in this embodiment are respectively a common cable and an anti-siphon cable. The anti-siphon cable passes through the sealing rubber plug 6 to be connected to the control device outside the cylinder. The provision of the anti-siphon cable can further reduce the probability of oil and gas leakage.
