For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0031] In an embodiment of the present application, as Figures 1-4As shown, provide a kind of anti-static electric wire harness, including protective sleeve 1, protective sleeve 1 mainly play the overall protection of internal harness group 3, prevent the various physical factors such as collision, extrusion, scratch etc. from outside to cause damage to electric wire harness, protective sleeve 1 one end fixedly connected with connector 2, connector 2 is used to realize the connection of electric wire harness and external equipment or other components, ensure the stable transmission of power or signal. Protective sleeve 1 inside is provided with harness group 3, and harness group 3 is responsible for transmitting power or signal. The side wall of connector 2 is provided with a protection assembly, which includes a protective sleeve 4, the side wall of the protective sleeve 4 is slidably connected to the side wall of the connector 2, the protective sleeve 4 can slide on the side wall of the connector 2, thereby providing additional protection for the connector 2 when not in use, the protective sleeve 4 is fixedly connected with a fixing sleeve 5 inside, the fixing sleeve 5 can closely fit the harness group 3, and the harness group 3 is provided with good sealing and fixing effect, to prevent the harness group 3 from shaking or shifting in the protective sleeve 1. The side wall of the protective sleeve 4 is fixedly connected with a connecting sleeve 6, the connecting sleeve 6 is slidably connected with a pressing block 7 inside, the pressing block 7 can be pressed by external force, the connecting sleeve 6 is fixedly connected with a fixing ring 9 inside, one end of the pressing block 7 is fixedly connected with an extrusion block 10, the side wall of the extrusion block 10 is sleeved with a first spring 8, the connector 2 is fixedly connected with a second spring 11 inside, one end of the second spring 11 is fixedly connected with a clamping block 12, the clamping block 12 can be fixed when the protective sleeve 4 is connected with the connector 2, to prevent the protective sleeve 4 from accidentally falling off. The side wall of the harness group 3 is fitted inside the fixing sleeve 5, to ensure the position stability of the harness group 3 in the protective sleeve 1, and the harness group 3 can also be better protected, one end of the first spring 8 is fixedly connected to the side wall of the pressing block 7, the other end of the first spring 8 is fixedly connected to the side wall of the fixing ring 9, to ensure the position stability of the first spring 8 during work, the side wall of the extrusion block 10 is slidably connected inside the fixing ring 9, to ensure the direction stability of the extrusion block 10 during movement, the side wall of the clamping block 12 is slidably connected inside the protective sleeve 4;

[0032] In the process of transporting the wire harness, firstly, the protective sleeve 4 is attached to the connector 2 to prevent the connector 2 from being impacted by external force and dust from entering during transportation. During sliding, the protective sleeve 4 will extrude the clamping block 12. The clamping block 12 plays a connecting and fixing role in this process until the protective sleeve 4 is completely attached to the connector 2. At this time, the clamping block 12 loses extrusion, and the second spring 11 pushes the clamping block 12 upward. The second spring 11 has elasticity and can store and release energy. When the clamping block 12 loses extrusion, the elastic restoring force of the second spring 11 pushes the clamping block 12 upward, so that the clamping block 12 is clamped into the inside of the protective sleeve 4, thereby completing the installation of the protective sleeve 4. This can effectively prevent static electricity from being generated due to friction between the wire harness groups 3 during transportation, and ensure the safety and stability of the wire harness during transportation. When it is necessary to remove the protective sleeve 4, the pressing block 7 is pressed to drive the extruding block 10 to extrude downward. The pressing block 7 serves as an operating part, facilitating the pressing operation of the user. The extruding block 10 moves downward under the action of the pressing block 7 to extrude the clamping block 12, so that the clamping block 12 is extruded and the second spring 11 is contracted. The second spring 11 will contract and store energy when the clamping block 12 is extruded. The clamping block 12 loses the fixing effect, and at this time the protective sleeve 4 can be removed, thereby completing the disassembly. Such a design makes the installation and disassembly of the protective sleeve 4 very convenient.

The side wall of the anti-static layer 16 is provided with a shielding layer 15, the anti-static layer 16 is made of conductive rubber, which can quickly conduct static electricity generated on the surface of the wire harness, preventing the accumulation of static electricity on the surface of the wire harness, avoiding interference with the signal transmission and electrical performance of the wire harness, and improving the stability and reliability of the wire harness. The side wall of the shielding layer 15 is provided with an insulating layer 14, the shielding layer 15 is made of metal woven mesh, which can effectively shield external electromagnetic interference, prevent external electromagnetic fields from affecting the signal transmission inside the wire harness, and ensure clear and stable signal transmission of the wire harness.

[0034] The protective sleeve 1 protects the internal structure of the wire harness, effectively resisting various mechanical damages from the outside world, such as collisions, extrusions, scratches, etc., ensuring that the internal wire harness will not be damaged by external physical forces. Its solid material and reasonable design provide a reliable barrier for the internal structure, ensuring the normal operation of the wire harness in various complex environments.

The anti-static layer 16 further enhances the anti-static effect, and is made of special anti-static material, which can effectively reduce the generation and accumulation of static electricity. When the wire harness is working, the anti-static layer 16 can quickly conduct the generated static electricity, avoiding interference with the signal transmission and electrical performance of the wire inside. It greatly improves the anti-static ability of the wire harness in combination with other anti-static measures. The shielding layer 15 helps to guide static electricity to the ground, and is usually made of conductive material, which can collect static electricity generated around the wire harness and guide it to the ground for release. This can effectively avoid the accumulation of static electricity inside the wire harness, reducing the risk of damage to the wire or causing fire accidents due to static discharge. At the same time, the shielding layer 15 can also reduce the influence of external electromagnetic interference on the wire harness. The insulating layer 14 prevents short circuit between the conductors 13 or between the conductors 13 and the outside world, and has good insulation performance, which can isolate the conductors 13 from the outside world, avoiding the contact between the conductors 13 and the conductive substances in the outside world to cause short circuit.

In the use process of the wire harness, the conductor 13 can withstand a certain degree of bending and stretching without easily breaking or damaging. This makes the wire harness group 3 more convenient and flexible during installation and use, and can adapt to various complex wiring environments.
