Description

Technical Field

[0001] This utility model belongs to the field of lead wire guide sleeve technology, and relates to the guide sleeve structure of electrical leads. Background Technology

[0002] Electrical leads are wires that extend outward from the component package. In a circuit, leads play a role in transmitting signals and energy, connecting various components, and ensuring stable circuit operation. Insulating sleeves can be installed on the outside of the leads for insulation.

[0003] The insulating sleeve, also known as the guide sleeve, is described in existing technology, such as the composite insulating sleeve for electrical leads disclosed in patent application CN202322060138.8. This sleeve includes an electrical casing, a lead body fixedly connected to one side of the casing, an outer sleeve mounted on another side of the casing, a flange fixedly connected to one side of the outer sleeve, and fixing blocks fixedly connected to both sides of the flange. A groove is formed on one side of each fixing block, and a slot is formed on one side wall of the groove. This composite insulating sleeve for electrical leads, by incorporating a sealing ring, a spring, a locking plate, and locking blocks, allows one end of the insulating sleeve to be secured to the surface of the electrical casing. The sealing ring provides a seal, preventing dust and rainwater from entering. In use, the insulating sleeve is fitted onto the surface of the lead body using a tool, the pull rod is pulled, causing the locking plate to rise and compressing the spring. The groove is then aligned with the locking block and pushed in, and the pull rod is released.

[0004] The disadvantage of the aforementioned composite insulating sleeve is that, in actual use, it cannot mark the relevant information of electrical leads and cannot better understand the lead parameters. Therefore, we designed a guide sleeve structure for electrical leads. Summary of the Invention

[0005] The purpose of this invention is to provide a guide sleeve structure for electrical leads to solve the problems mentioned in the background art.

[0006] The purpose of this utility model can be achieved through the following technical solution: a guide sleeve structure for electrical leads, including a rubber insulating outer sheath, the rubber insulating outer sheath being a hollow structure with a plastic insulating inner sheath inside the hollow, a lead wire guiding through hole being opened at the center of the plastic insulating inner sheath, a nylon clamp being fitted and installed on the outer surface of the rubber insulating outer sheath, and an information display nameplate being installed at one end of the nylon clamp.

[0007] In the aforementioned guide sleeve structure for electrical leads, the end of the rubber insulating outer sheath is provided with four annularly distributed through holes, and each through hole is fitted with a reinforcing rib.

[0008] In the above-mentioned guide sleeve structure for electrical leads, a sleeve positioning block is installed at the bottom center of the rubber insulating outer sheath, and an inlet plug is provided at the bottom of the sleeve positioning block.

[0009] In the above-mentioned guide sleeve structure for electrical leads, the other side of the inner cavity of the lead guide through-hole is provided with symmetrical U-shaped notches, and elastic connecting pads are installed inside the two U-shaped notches. Lead contacts are installed at one end of the two elastic connecting pads.

[0010] In the aforementioned guide sleeve structure for electrical leads, a waterproof retaining ring is installed on one side of the inner cavity of the lead guide through-hole.

[0011] In the aforementioned guide sleeve structure for electrical leads, the end face of the rubber insulating outer sheath is flush with the end face of the plastic insulating inner sheath, and the thickness of the rubber insulating outer sheath is greater than the thickness of the plastic insulating inner sheath.

[0012] Compared with existing technologies, the advantages of the guide sleeve structure for electrical leads in this utility model are as follows: By installing nylon clamps on the outer surface of the rubber insulating outer sheath, and attaching an information display nameplate to one end of the nylon clamps, relevant information about the leads can be marked on the label, facilitating quick access to lead information during maintenance. The structure is simple and easy to use. Furthermore, by designing the rubber insulating outer sheath as a hollow structure with a plastic insulating inner sheath inside, it better protects the leads while ensuring overall insulation.
