Description

Technical Field

[0001] This utility model relates to the field of power tool accessories, and in particular to a connecting cable for power tools. Background Technology

[0002] Power tools are small tools that use a small electric motor or electromagnet as power to drive a working head through a transmission mechanism. Power tools have the advantages of being portable, easy to operate, and versatile. They can greatly reduce labor intensity, improve work efficiency, and realize the mechanization of manual operations. Therefore, they are widely used in fields such as construction, home decoration, automobiles, machinery, power, bridges, and gardening, and have also entered many households.

[0003] Power tool cables are important components used to transmit electrical energy and signals in power tools. Their performance directly affects the usability and safety of the power tools. Power tool cables come in single-core and multi-core types; a single-core cable consists of a single conductor, while a multi-core cable consists of multiple conductors twisted together.

[0004] Existing multi-core power tool cables typically include a wire and two terminals: a first connector for connecting to the product and a second connector for plugging into a power socket. The wire itself is usually straight. However, due to its straight shape and the material, the straight wire has poor elasticity, making it prone to breakage when subjected to pulling or compressing forces. Furthermore, since there are no other structures on the outer sheath, the surface of the cable will come into contact with the contact surface and rub against it over time, causing wear and tear on the outer sheath and affecting the cable's lifespan.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a connecting cable for power tools. Through the design of a flexible metal layer, it can be freely contracted and stretched according to actual needs. The outer sheath layer follows the bending of the inner flexible metal layer, thereby controlling the length of the connecting cable. Secondly, the design includes a stop and several locking parts. During use, these locking parts engage with a suitable mating component (such as another connector) to ensure a secure connection, prevent accidental loosening, and guarantee the reliability of the electrical connection. Furthermore, it can precisely define the insertion position of the connector body, ensuring accurate mating of the connecting components and guaranteeing the stability and reliability of the connector connection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A connecting cable for power tools includes a connector body and a plurality of wires; the connector body includes at least a plastic base, the plastic base having a stop portion and a plurality of snap-fit ​​portions, the plurality of snap-fit ​​portions extending from the upper end surface of the plastic base, wherein the rear ends of the plurality of snap-fit ​​portions are connected to the front ends of the stop portion; each of the front ends of the plurality of snap-fit ​​portions has a guide surface; the rear end of the plastic base has a plurality of mounting tubes for mounting the wires, one end of the plurality of wires being mounted in the mounting tubes;

[0009] Each of the aforementioned conductors includes a conductor, a flexible metal layer, an insulating layer, an outer sheath, and a wear-resistant coating; the flexible metal layer is flexible and deformable and covers the outer surface of the conductor; the insulating layer covers the flexible metal layer, the outer sheath covers the insulating layer, and the wear-resistant coating is sprayed onto the outer sheath.

[0010] As a preferred embodiment, the outer surface of the outer layer is provided with a corrosion-resistant coating and a waterproof coating. The corrosion-resistant coating is sprayed on the outside of the outer layer, the waterproof coating is sprayed on the outside of the corrosion-resistant coating, and the wear-resistant coating is sprayed on the outside of the waterproof coating.

[0011] As a preferred embodiment, the corrosion-resistant coating is an epoxy paint.

[0012] As a preferred embodiment, the waterproof coating is a polymer cement-based waterproof coating.

[0013] As a preferred embodiment, the wear-resistant coating is an epoxy resin coating.

[0014] As a preferred embodiment, the plurality of conductors further includes a tensile layer, which covers the outer surface of the soft metal layer.

[0015] As a preferred embodiment, the tensile layer is a polyester fiber layer or a nylon fiber layer.

[0016] As a preferred embodiment, both the outer sheath and the insulation layer are made of PVC material.

[0017] As a preferred embodiment, the plurality of wires are respectively defined as a first wire, a second wire, a third wire, and a fourth wire, and one end of the first wire, the second wire, the third wire, and the fourth wire is respectively installed on a corresponding mounting pipe.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the design of a soft metal layer, which can be arbitrarily contracted and stretched according to actual needs. The outer outer layer follows the bending of the inner soft metal layer, thereby controlling the length of the connecting wire and making it easy to carry. Secondly, the design of the wear-resistant coating enhances the wear resistance of the connecting wire.

[0019] Next is the structural design of the connector body. The plastic base is provided with a stop and several snap-fit ​​parts. In use, the snap-fit ​​parts are used to engage with the appropriate mating parts (such as another connector) to ensure a stable connection, prevent accidental loosening, and ensure the reliability of the electrical connection. The design of the stop can precisely limit the insertion position of the connector body, ensuring that the connecting parts can be accurately mated and preventing problems such as poor contact or damage to internal pins due to incomplete or excessive insertion, thus ensuring the stability and reliability of the connector connection.

[0020] Finally, the guide section is designed to guide the connector body to align accurately during insertion, preventing reverse insertion or misalignment.

[0021] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description
