Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, and specifically relates to an embedded conductive rubber belt. BACKGROUND

[0002] Traditional conductive belts mostly adopt metal woven belts or single wire structures, and have problems such as poor flexibility, easy oxidation, unstable contact resistance and the like. Although conductive rubber has flexibility, uneven distribution of single conductive filler can easily lead to stable electrical effect.

[0003] At present, there are conductive rubber belts embedded with metal wires on the market, and the structure has the following defects:

[0004] 1. The copper wire is directly inserted into the round hole of the tungsten steel block, which causes the contact interface to be loose;

[0005] 2. The rubber hole is easily crushed when the bolt is connected, and the nut is loose in vibration;

[0006] 3. The exposed wire is not well protected and is easily damaged by foreign matter;

[0007] 4. The end connection structure is often weak, resulting in breakage or poor contact and other quality problems.

[0008] Therefore, there is an urgent need for a conductive rubber belt with high conductivity, fatigue resistance and reliable end connection. CONTENT OF THE UTILITY MODEL

[0009] In view of the defects in the prior art, the utility model aims to provide an embedded conductive rubber belt, which significantly improves the conductivity stability, mechanical strength and environmental adaptability by optimizing the internal conductive structure and end connection process.

[0010] To achieve the above purpose, the utility model adopts the technical scheme: an embedded conductive rubber belt, comprising a conductive rubber main body, a tungsten steel block and a cover plate; at least one copper wire is arranged in the conductive rubber main body along the length direction thereof, the proximal end of the copper wire is provided with a first terminal, and the distal end of the copper wire is provided with a second terminal; the tungsten steel block is arranged inside the proximal end of the conductive rubber main body and connected with the first terminal of the copper wire through a first rivet; the cover plate is arranged outside the distal end of the conductive rubber main body and connected with the second terminal of the copper wire through a second rivet.

[0011] Further improvement lies in that the tungsten steel block is provided with a vulcanization positioning hole.

[0012] Further improvement lies in that the vulcanization positioning hole is a long circular hole.

[0013] Further improvement lies in that the cover plate is provided with an assembly hole, and a bolt passes through the assembly hole to fix the cover plate on the vehicle frame.

[0014] Further improvement lies in that the distal end of the conductive rubber body is provided with a first through hole for the second rivet to pass through.

[0015] Further improvement lies in that the distal end of the conductive rubber body is provided with a second through hole corresponding to the assembly hole for the bolt to pass through.

[0016] Further improvement lies in that the width of the cover plate is greater than that of the conductive rubber body, and the edge of the cover plate is bent inward to form a flange portion after extending out of the conductive rubber body.

[0017] Further improvement lies in that the copper wire is provided with two wires symmetrically distributed on both sides of the width center line of the conductive rubber body.

[0018] Further improvement lies in that the distance between the two copper wires is 15-30 mm.

[0019] Further improvement lies in that the length of the conductive rubber body is 2000-3000 mm, the width is 40-60 mm, and the thickness is 8-12 mm; and the conductive rubber body is vulcanized from a conductive rubber semi-finished upper sheet and a conductive rubber semi-finished lower sheet.

[0020] The beneficial effects of the utility model lie in:

[0021] 1. High conductivity and stability: the double parallel copper wires are symmetrically embedded in the rubber matrix, tightly combined with the matrix through the vulcanization process, ensuring uniform distribution of the conductive filler, reducing the contact resistance, and improving the current conduction efficiency.

[0022] 2. Reliable end connection: the proximal end is riveted with the terminal and then the tungsten steel block in sequence, and the distal end adopts a cover plate riveting structure, avoiding the problem of traditional bolt crushing the glue or loosening, and enhancing the mechanical strength and anti-vibration performance.

[0023] 3. Full protection design: the copper wire is fully wrapped in the rubber matrix, and only the riveting interface is exposed at both ends, effectively preventing foreign object damage and oxidation corrosion, and prolonging the service life.

[0024] 4. Process optimization: rivet head surface is flat, reducing installation interference; vulcanization and riveting process are combined to ensure the integrity of the assembly and the reliability of the assembly.

[0025] 5. Environmental adaptability: suitable for complex working conditions, especially meeting the high safety, fatigue resistance and long-term stability requirements of hazardous chemical transportation vehicles for conductive and static devices. BRIEF DESCRIPTION OF DRAWINGS
