Technical Field

[0001] The invention relates to the technical field of wire harnesses, in particular to a wire harness with a protective function and a use method thereof. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and is generally H-shaped.

[0003] When the existing wiring harness is in use, the two ends of the wiring harness are respectively connected to the electronic components and power supply equipment that consume electricity. Since the vehicle is in an extreme temperature, frequent vibration environment or abnormal installation and maintenance process when driving, the wiring harness may be subjected to a certain degree of friction, which may easily cause the outer skin of the wiring harness to be damaged, the insulation layer to be damaged, or the wires to be exposed. At this time, the wiring harness needs to be replaced as a whole, and the worn parts of the wiring harness cannot be maintained separately. For this reason, a wiring harness with a protective function and a method for using the same are proposed. Summary of the invention

[0004] The object of the present invention is to provide a wire harness with a protective function and a method of using the same, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wire harness with a protective function, comprising a wire harness body, a plurality of wire cores are arranged inside the wire harness body, a sponge layer is wrapped outside the wire core, an insulating layer is wrapped outside the sponge layer, a high-temperature resistant layer is wrapped outside the insulating layer, a flame-retardant layer is wrapped outside the high-temperature resistant layer, an anti-interference layer is sleeved outside the flame-retardant layer, a waterproof layer is sleeved outside the anti-interference layer, a wear-resistant layer is sleeved outside the waterproof layer, a replacement component is arranged on one side of the wear-resistant layer, and a maintenance component is arranged on one side of the replacement component;

[0006] The replacement assembly includes a plurality of annular protrusions and a plurality of bases, a connecting groove is provided on one side of the base, and an inclined surface is provided on the outer side of the annular protrusion.

[0007] Preferably, a rubber strip is integrally formed on a side of the base away from the connecting groove, and the outer side of the annular protrusion is inserted into the inner side of the connecting groove.

[0008] Preferably, a plurality of limiting grooves are provided on the outer side of the wear-resistant layer, one side of the annular protrusion is fixed to the inner side wall of the limiting groove, and the outer side of the base is inserted into the inner side of the limiting groove.

[0009] Preferably, the maintenance assembly comprises a plurality of slide posts and a plurality of connecting plates, one side of the connecting plate is provided with an insertion groove, and an inserting plate is fixed to the bottom of the slide post.

[0010] Preferably, a plurality of locking grooves, a first sliding groove and a second sliding groove are respectively provided inside the wear-resistant layer, and the outer side of the inserting plate is inserted into the inner side of the inserting groove.

[0011] Preferably, the outer side of the connecting plate is inserted into the inner side of the locking groove, and the outer side of the plug plate is slidably connected to the inner side of the second sliding groove.

[0012] Preferably, a slide plate is slidably connected to the inner side of the first slide groove, and one side of the slide plate is fixed to one side of the plug plate.

[0013] Preferably, a spring is connected between one side of the slide plate and the inner side of the first slide groove, and a pull block is fixed to one end of the slide column away from the plug plate.

[0014] Preferably, one side of the connecting plate is fixed to one side of the wear-resistant layer, and two ends of the wiring harness body are respectively connected to a female connector and a male connector.

[0015] The present invention also provides a method for using a wiring harness with a protective function, comprising the following steps:

[0016] S1. Connect the main body of the wiring harness, connect the male connector of the main body of the wiring harness to the power-consuming electronic component, and then connect the female connector to the power supply equipment;

[0017] S2. When the harness body is in use, the rubber strip on the outside of the wear-resistant layer is preferably used to contact the outside world to protect the harness body. When the rubber strip is worn, you only need to use tweezers to clamp one side of the rubber strip and remove it from the inside of the limit groove, and then insert the new base with the rubber strip into the inside of the limit groove.

[0018] S3. Repair of the wiring harness body. When the wire core inside the wiring harness body needs maintenance, you only need to pull the pull block to one side. The pull block drives the slide column and the second slide groove to move, so that the slide plate slides inside the first slide groove. The slide plate compresses the first slide groove. At this time, the plug plate leaves the inner side of the insertion groove, and the wear-resistant layer connection can be separated. Then the sponge layer, insulation layer, high temperature resistant layer, flame retardant layer, anti-interference layer and waterproof layer can be separated in turn, and then the wire core can be repaired.

[0019] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects:

[0020] 1. When the wiring harness body is in use, the rubber strip on the outside of the wear-resistant layer is used to contact the outside world to protect the wiring harness body. At the same time, the internal sponge layer, insulation layer, high temperature resistant layer, flame retardant layer, anti-interference layer and waterproof layer are used to protect the wire core inside the wiring harness body. Using the above multi-layer structure to protect the wire core can improve the durability, reliability and safety of the wiring harness body and ensure the normal operation of the vehicle electrical system.

[0021] 2. When the rubber strip is worn, insert a new base with a rubber strip into the inner side of the limiting groove. Under the squeezing action of the annular protrusion, the two clamping feet of the base are tightly fitted into the inner side of the limiting groove. Then the new rubber strip can be installed on the inner side of the limiting groove. The operation is simple and convenient. The rubber strip can be installed on the outer side of the wear-resistant layer through the simple cooperation of the annular protrusion and the connecting groove, which eliminates the tedious disassembly and assembly steps, reduces the time and labor cost of replacement, and can replace the worn rubber strip separately, which improves the convenience of maintenance of the wiring harness body after wear.

[0022] 3. When the wire core inside the harness body needs maintenance, you only need to pull the pull block to one side, and the pull block drives the slide column and the second slide slot to move, so that the plug plate leaves the inner side of the insertion slot, and then pull the wear-resistant layer to both sides to separate the connection of the wear-resistant layer, and then repair the wire core. The use of maintenance components only requires separating each layer at the location that needs to be repaired during the repair process, and the layers at other locations remain intact. This can avoid the impact and damage to other layers, maintain the overall structural integrity of the harness, reduce the reassembly and debugging work after repair, and improve the maintenance efficiency of the harness body during repair.
