Description

Technical Field

[0001] This application belongs to the field of cable pin manufacturing technology, specifically relating to a convenient, crimp-free pin for easy installation. Background Technology

[0002] In existing technologies, traditional connectors typically require screws or other fasteners to secure the wires and ensure connection stability and continuity. While this connection method meets basic electrical connection requirements to some extent, it also has several drawbacks. Firstly, the installation process is cumbersome, requiring the individual tightening of screws to secure the wires. This not only consumes significant manpower and time but also drastically reduces efficiency in applications where high installation efficiency is crucial, such as assembling electrical equipment on large-scale production lines or emergency repairs. Secondly, due to the tiny gaps at the screw connection points, waterproofing is poor. In humid environments or when exposed to liquid splashes, moisture can easily seep in, leading to short circuits, corrosion, and other malfunctions, affecting the connector's lifespan and connection reliability.

[0003] The emergence of crimp-free connectors offers a new solution to these problems. These connectors feature a unique structural design that eliminates the need for traditional screw-based crimping, enabling rapid, crimp-free installation. Through a specially designed elastic clamping device or crimp terminal, the connector firmly holds the wire during insertion using its own elastic deformation, eliminating the need for additional screws and tightening tools. This significantly reduces installation time and improves efficiency, making it particularly suitable for applications where ease of installation is paramount.

[0004] Furthermore, crimp-free connectors also demonstrate significant advantages in waterproofing. Some advanced crimp-free connector products, through optimized housing structure and sealing design, form an effective sealing barrier at the connection between the connector and the wire, effectively preventing the intrusion of external impurities such as moisture and dust. This enhances the stability and reliability of the connector in harsh environments, extends its service life, and reduces equipment maintenance costs.

[0005] Therefore, given the shortcomings of traditional connectors in terms of ease of installation and waterproofing, developing a convenient, pressure-free connector that combines rapid installation and good waterproofing is of great practical significance. It can improve electrical connection efficiency, enhance the adaptability of equipment in complex environments, and meet the high-performance requirements of modern electrical systems for connection devices. Utility Model Content

[0006] This application addresses the technical problems of traditional pins requiring screws or other fasteners to clamp the wires, resulting in cumbersome installation, poor user experience, and insufficient waterproofing due to tiny gaps at the screw-wire connection. It proposes a convenient, crimp-free pin for easy installation.

[0007] This application adopts the following solution: a convenient installation of a crimp-free connector, comprising a clamp on a conductor core, a torsion spring sleeved on the conductor core, a connector sleeved on the torsion spring, and a protective layer covering both the connector and the conductor. The clamp comprises an annular body, a plurality of clamping pieces on one end of the annular body, a clamping hole formed by the plurality of clamping pieces, and a mounting groove formed by the annular body and the clamping pieces. The plurality of clamping pieces are spaced apart around the axis of the annular body. The conductor core is matched and disposed in the clamping hole, and the connector is matched and disposed in the mounting groove.

[0008] In some feasible embodiments, each of the clips is tilted toward the other end of the annular body, and when the conductor core is matched and disposed in the clamping hole, each of the clips abuts against the conductor core to clamp the conductor core.

[0009] In some feasible embodiments, the tilt angle of the clip relative to the other end of the annular body is defined as A, wherein A satisfies the following relationship: 45°<A≤60°.

[0010] In some feasible embodiments, a clearance groove is provided between two adjacent clips.

[0011] In some feasible embodiments, multiple torsion springs are provided at intervals along the length of the conductor core.

[0012] In some feasible embodiments, the torsion spring includes two spaced-apart connecting rings and a tightening portion disposed between the two connecting rings. The tightening portion is made of an elastic material, and the cross-sectional area of ​​the tightening portion contracts from both ends to the middle.

[0013] In some feasible embodiments, the pin includes a connecting portion, a pin tip disposed on the connecting portion, and a connecting hole disposed on the connecting portion, the torsion spring extending into the connecting hole, and the connecting portion being disposed within the mounting groove.

[0014] In some feasible embodiments, the protective layer is made of any one of silicone, rubber, nylon, polyvinyl chloride, and polyethylene.

[0015] In some feasible embodiments, the inner side of the protective layer is provided with a plurality of protrusions spaced apart along its length.

[0016] Compared with the prior art, this application has the following beneficial effects:

[0017] This application provides a convenient, crimp-free connector, comprising a clamp on the conductor core, a torsion spring on the conductor core, a connector on the torsion spring, and a protective layer covering both the connector and the conductor. The clamp includes a ring-shaped body, multiple clips on one end of the ring-shaped body, a clamping hole formed by the multiple clips, and a mounting groove formed by the ring-shaped body and the clips. The multiple clips are spaced apart around the axis of the ring-shaped body. The conductor core is fitted into the clamping hole, and the connector is fitted into the mounting groove. Compared to traditional connectors that require screws or other fasteners to clamp the conductor, resulting in cumbersome installation and potential waterproofing issues, this application achieves rapid connection between the connector and the conductor through the clamping hole and mounting groove formed by the multiple clips of the clamp, combined with the elastic force of the torsion spring. No additional fasteners are required, making the installation process simple and efficient. Meanwhile, the protective layer's encapsulation design effectively avoids the problem of poor waterproofing caused by tiny gaps at the connection between screws and wires in traditional pins, significantly improving the waterproofing performance and reliability of the pins. This can effectively extend the service life of the pins, reduce equipment maintenance costs, and enhance user experience and customer satisfaction. It also has the advantages of simple structure, easy operation, low implementation cost, and ease of promotion and implementation. Attached Figure Description

[0028] Combination Figure 1-10 The following description further illustrates the technical solution proposed in this application. This application provides a convenient, crimp-free connector, comprising a clamp 1 disposed on a conductor core, a torsion spring 2 sleeved on the conductor core, a connector 3 sleeved on the torsion spring 2, and a protective layer 4 covering both the connector 3 and the outer periphery of the conductor. The clamp 1 includes an annular body 10, a plurality of clamping pieces 11 disposed at one end of the annular body 10, a clamping hole 12 formed by the plurality of clamping pieces 11, and a mounting groove 13 formed by the annular body 10 and the clamping pieces 11. The plurality of clamping pieces 11 are spaced apart around the axis of the annular body 10, the conductor core is matched and disposed within the clamping hole 12, and the connector 3 is matched and disposed within the mounting groove 13.

[0029] In actual implementation, by setting clamps, the conductor core can be clamped to prevent it from rotating relative to the conductor core. By setting torsion springs, the contact area between the conductor core and the pin can be increased, the conductivity of the pin can be enhanced, the gap between the conductor and the pin can be reduced, and the pin can be effectively prevented from loosening.

[0030] This application provides a convenient, crimp-free connector, comprising a clamp on a conductor core, a torsion spring on the conductor core, a connector on the torsion spring, and a protective layer covering both the connector and the conductor. The clamp includes an annular body, multiple clips on one end of the annular body, a clamping hole formed by the clips, and a mounting groove formed by the annular body and the clips. The clips are spaced apart around the axis of the annular body. The conductor core is fitted into the clamping hole, and the connector is fitted into the mounting groove. The clamping hole and mounting groove, formed by the multiple clips, combined with the elastic force of the torsion spring, enable rapid connection between the connector and the conductor without additional fasteners, making the installation process simple and efficient. The protective layer significantly improves the connector's waterproof performance and reliability, offering advantages such as simple structure, easy operation, low implementation cost, and ease of widespread adoption.

[0031] In this embodiment, each of the clamping pieces 11 is tilted toward the other end of the annular body 10. When the conductor core is matched and disposed in the clamping hole 12, each of the clamping pieces 11 abuts against the conductor core to clamp the conductor core.

[0032] In actual implementation, by setting up clamps, the conductor core can be held in place, preventing the clamps from rotating relative to the conductor core. Through the structural design of the clamping plates tilting towards the other end of the ring-shaped body, when the conductor core is properly positioned within the clamping hole, the clamping plates abut against the conductor core to achieve clamping.

[0033] In practical implementation, by setting inclined clips, the clips can be tightly pressed against the conductor core, thus firmly clamping the conductor core and effectively preventing rotation relative to the conductor core, improving the stability and reliability of the connection. Simultaneously, the tight contact between the clips and the conductor core increases the contact area between the conductor core and the pin, thereby enhancing the conductivity of the pin, reducing the gap between the conductor and the pin, and making the connection between the pin and the conductor core even tighter, effectively preventing the pin from loosening and ensuring the stability and safety of the electrical connection.

[0034] Furthermore, the clip surface is provided with anti-slip texture, which can enhance the friction between the clip and the conductor core and prevent the conductor core from slipping.

[0035] In this embodiment, the tilt angle of the clip 11 relative to the other end of the annular body 10 is defined as A, and A satisfies the following relationship: 45°<A≤60°.

[0036] In actual implementation, A=60°.

[0037] In this embodiment, a clearance groove 14 is provided between two adjacent clips 11.

[0038] In this embodiment, multiple torsion springs 2 are spaced apart along the length of the conductor core.

[0039] In actual implementation, by setting multiple torsion springs, the conductor core can be effectively bundled together, increasing the contact area between the conductor core and the pin.

[0040] In this embodiment, the torsion spring 2 includes two spaced-apart connecting rings 20 and a tightening part 21 located between the two connecting rings 20. The tightening part 21 is made of elastic material, and the cross-sectional area of ​​the tightening part 21 shrinks from both ends to the middle.

[0041] In this embodiment, the pin 3 includes a connecting part 30, a pin end 31 disposed on the connecting part 30, and a connecting hole 32 disposed on the connecting part 30. The torsion spring 2 extends into the connecting hole 32, and the connecting part 30 is disposed in the mounting groove 13.

[0042] In actual implementation, such as Figure 10 As shown, the needle tip can be replaced with a connecting terminal to meet the usage requirements of different application scenarios.

[0043] In this embodiment, the protective layer 4 is made of any one of silicone, rubber, nylon, polyvinyl chloride, or polyethylene.

[0044] In actual implementation, the protective layer is made of silicone. By using silicone, the waterproof performance of the pin can be effectively improved and the service life of the pin can be extended.

[0045] In this embodiment, the inner side of the protective layer 4 is provided with a plurality of protruding teeth 40 at intervals along its length.

[0046] In actual implementation, by setting protrusions on the inside of the protective layer, and using elastic materials such as silicone rubber, the outer diameter of the cable is larger than the protrusions. During installation, the cable needs to be squeezed in. After installation, the protrusions can tightly wrap the cable, thereby achieving the functions of waterproofing and anti-slip.

[0047] This application provides a convenient, crimp-free connector, comprising a clamp on a conductor core, a torsion spring on the conductor core, a connector on the torsion spring, and a protective layer covering both the connector and the conductor. The clamp includes an annular body, multiple clips on one end of the annular body, a clamping hole formed by the clips, and a mounting groove formed by the annular body and the clips. The clips are spaced apart around the axis of the annular body. The conductor core is fitted into the clamping hole, and the connector is fitted into the mounting groove. The clamping hole and mounting groove, formed by the multiple clips, combined with the elastic force of the torsion spring, enable rapid connection between the connector and the conductor without additional fasteners, making the installation process simple and efficient. The protective layer significantly improves the connector's waterproof performance and reliability, offering advantages such as simple structure, easy operation, low implementation cost, and ease of widespread adoption.
