Embodiment Construction

[0013] The invention solves the problem of protecting the thin wire harness in the air conditioner ligation wire harness, and fundamentally keeps up with the problem of protecting the wire harness of the air conditioner system.

[0014] In the present invention, the fuse 1 is directly added to the thin wire harness part of the air conditioner wire harness ligation to solve the problem that the fuse cannot be directly added from the whole vehicle. Fuse 1 is reliably connected in series with the wire harness. When fuse 1 is protected, the wire harness will be disconnected. The fuses of the air conditioning system are directly installed on the wire harness.

[0015] To figure 1 The working harness of the blower M and the control harness of the A / C SW are shown as examples. The blower M working wiring harness in the air conditioning system is connected with the A / C SW control wiring harness. The A / C SW control wiring harness collects high-level working signals from the blower M worki...

Abstract

The invention discloses a protective circuit for an automobile air conditioner system correlation signal line. The protective circuit is characterized in that fuse wires are stringed into a bundled fine wire harness part of an air conditioner harness of the protective circuit. By the adoption of the structure, the protection circuit is unique in design, safe and reliable and solves the problem that fuse wires and multi-bundled harness fine wires cannot be added to a fuse wire box.

Description

Technical field [0001] The invention relates to the field of automotive air conditioning design and production, and in particular to a protection circuit for signal lines associated with automotive air conditioning systems. Background technique [0002] At present, the wiring harness protection requirements of automobile air-conditioning systems are getting higher and higher, and various risks must be considered during the design and design measures must be taken to avoid risks. Among them, the short-circuit of the wiring harness causes the most serious consequences of rapid heating and combustion, so the short-circuit protection measures of the air-conditioning wiring harness are particularly important. [0003] At present, the air-conditioning wiring harness adopts more short-circuit burning protection for the vehicle to add fuse prevention, prevention of flame retardant wiring harness tape wrapping, etc. However, these precautions can only protect single-channel type wiring har...
