Description

Generator harness assembly

technical field

The utility model relates to a generator wiring harness assembly.

Background technique

The wiring harness is the wiring part that connects various electrical equipment in the circuit. It is composed of insulating sheaths, terminal blocks, wires and insulating wrapping materials. It is usually a group of metal wires and cables bound together to connect and transfer electrical equipment. signal between power supplies. However, due to the large number of wires, the wires at the inlet and outlet ends of the wire harness are always messy, and the wires can slide relative to the insulation material in the insulation material, making the contact contact of the wire harness unreliable, and the wires are easy to be mistaken, and there is a certain potential safety hazard.

Contents of the invention

In order to solve the problems of unreliable contact of the existing wire harness contacts in the background technology and easy confusion of wire harness wires, the utility model provides a generator wire harness assembly.

The technical solution of the utility model is: a generator wiring harness assembly, including an incoming wiring harness connected to a junction box and an outgoing wiring harness connected to an electrical appliance, the outer casing of the incoming wiring harness is provided with a wire protection tube, and the described The incoming wire harness is divided into multiple branch lines in the wire protection tube to form multiple outlet wire harnesses. The outgoing wire harness is provided with a clip joint and multiple fixed joints for bolt connection, and the wire protection tube is provided with a bell mouth Horn-shaped sheaths facing each other, the horn-shaped sheath is provided with an annular groove, the connection between the fixed joint and the outgoing wire harness is provided with a heat-shrinkable tube, and the heat-shrinkable tube includes a polyolefin alloy outer layer and hot melt adhesive inner layer.

As an improvement of the present invention, the diameter of the end of the heat-shrinkable tube close to the outgoing wire harness is larger than the diameter of the end close to the fixed joint, and the two ends of the heat-shrinkable tube transition smoothly.

As a further improvement of the utility model, the wire protection pipe is made of PE plastic, PP plastic or PVC material.

As a further improvement of the utility model, an adhesive tape is bound between the outlet wire harness and the wire protection tube.

As a further improvement of the present utility model, a marking sleeve is provided on the outgoing wire harness.

The beneficial effect of the utility model is that the setting of the trumpet-shaped sheath makes the wiring harness in the wire protection tube not easy to slide, and the design of the annular groove on the horn-shaped sheath makes the product easier to install and use. At the same time, the utility model is equipped with a heat-shrinkable tube. The outer layer of the heat-shrinkable tube has the advantages of softness, low-temperature shrinkage, insulation, anti-corrosion, and wear resistance, and the inner layer has the advantages of low melting point, good adhesion, and water-tightness. The outgoing wire harness is reliably connected.

Detailed ways

Below in conjunction with accompanying drawing, the utility model embodiment is further described:

As shown in Figure 1, a generator wiring harness assembly includes an incoming wiring harness 1 connected to a junction box and an outgoing wiring harness 2 connected to an electrical appliance. The above-mentioned incoming wire harness 1 is divided into multiple branch lines in the wire protection tube 3 to form multiple outgoing wire harnesses 2, and the described outgoing wire harness 2 is provided with a clip joint 21 and a plurality of fixed joints 22 for bolt connection. The protective wire tube 3 is provided with a horn-shaped sheath 4 opposite to the bell mouth. The horn-shaped sheath 4 is provided with an annular groove 41, and the connection between the fixed joint 22 and the outgoing wire harness 2 is provided with a heat sink. The shrinkable tube 5, the heat-shrinkable tube 5 includes an outer layer of polyolefin alloy and an inner layer of hot melt adhesive. The diameter of the end of the heat-shrinkable tube 5 close to the wire harness 2 is larger than the diameter of the end close to the fixed joint 22 , and the two ends of the heat-shrinkable tube 5 transition smoothly. Such a structure has a better tightening function, making the contact of the contact fixed joint more reliable. The wire protection tube 3 is made of PE plastic (Polyethylene plastic), PP plastic (polypropylene plastic) or PVC (Polyvinylchloride polyvinyl chloride) material. An adhesive tape 6 is bound between the outlet wire harness 2 and the wire protection tube 3 . Such a structure prevents the installation of the outgoing wiring harness from affecting the installation of the incoming wiring harness. The outgoing wire harness 2 is provided with a marking sleeve 7 . Such a structure avoids the contact of the outgoing wire harness, affects the performance of the product, and eliminates potential safety hazards. The beneficial effect of the utility model is that the setting of the trumpet-shaped sheath makes the wiring harness in the wire protection tube not easy to slide, and the design of the annular groove on the trumpet-shaped sheath makes the product easier to install and use. At the same time, the utility model is equipped with a heat-shrinkable tube. The outer layer of the heat-shrinkable tube has the advantages of softness, low-temperature shrinkage, insulation, anti-corrosion, and wear resistance, and the inner layer has the advantages of low melting point, good adhesion, and water-tightness. The outgoing wire harness is reliably connected.
