Description

Technical Field

[0001] This utility model relates to the field of clip technology, and in particular to a charging clip. Background Technology

[0002] The charging clip is the core connection device for charging batteries in auto repair work. Its front end holds the battery terminals through electrodes, and its rear end connects to the charging cable to realize power transmission.

[0003] Currently, there is a type of charging clip on the market with an insulating rubber sleeve. This sleeve simply covers the clip body with a single, closed loop, without any limiting or securing features. This crude design makes the rubber sleeve prone to axial displacement or even complete detachment during frequent opening and closing operations. This not only forces operators to repeatedly adjust the parts, affecting work efficiency, but also severely weakens the insulation performance. When the rubber sleeve accidentally shifts, the exposed metal clip body may cause an accidental short circuit or electric shock, posing a significant safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a charging clip to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A charging clip includes a pair of upper and lower metal clips hinged together, the upper and lower metal clips forming a clip-like conductor.

[0007] Both the upper and lower metal clamps include a clamping head and a handle. A torsion spring is built into the hinge of the upper and lower metal clamps. Each of the upper and lower metal clamps is fitted with a matching insulating sleeve. The insulating sleeve includes a semi-enclosed first sleeve connected to the clamping head and a fully enclosed second sleeve connected to the handle. The inner side of the handle of both the upper and lower metal clamps is provided with reverse teeth. These reverse teeth are angled from the handle towards the clamping head. During installation, the handle is fully inserted into the fully enclosed second sleeve through the opening of the semi-enclosed first sleeve. The reverse tooth design makes the insulating sleeve easy to install and difficult to detach.

[0008] Preferably, the upper metal clamp includes a first semi-circular hinge seat disposed at the hinge joint between the upper and lower metal clamps; the lower metal clamp includes a second semi-circular hinge seat disposed at the hinge joint between the upper and lower metal clamps; the first and second semi-circular hinge seats are hinged together by a rivet; the rivet is disposed on the side of both the first and second semi-circular hinge seats away from the clamping head. The rearward movement of the rivet hinge position increases the contact area between the clamping head and the clamped object when clamping.

[0009] Preferably, the clamping head includes a biting tooth portion and a tiger's mouth portion; the tiger's mouth portion is provided with a tooth-shaped protrusion, which makes the clamping more stable.

[0010] Preferably, both the upper and lower metal clamps have wire connection portions at the ends of their handles to facilitate wire connection.

[0011] Preferably, the end of the fully enclosed second socket of the insulating sheath is provided with a wire sheath that matches the wire connection portion. During connection, after the wire passes through the sheath, it is electrically crimped with the wire connection portion to protect the wire connection portion and extend its service life.

[0012] Preferably, the inner side of the fully enclosed second socket of the insulating sleeve is provided with horizontal anti-slip texture to increase the friction when gripping and prevent slippage.

[0013] Compared with the prior art, the charging clip of this application has the following advantages:

[0014] 1. Dual-locking structure design of the insulating sleeve: A combination of a semi-enclosed first socket and a fully enclosed second socket, along with a reverse tooth design on the inner side of the handle, achieves triple protection: First, the semi-enclosed structure provides precise positioning at the clamping head, preventing the sleeve from shifting forward and causing incomplete clamping surface coverage; second, the fully enclosed structure completely covers the conductive area of ​​the handle, eliminating the axial movement risk of traditional simple socketing; finally, the inclined design of the reverse teeth creates a one-way locking effect during insertion, ensuring ease of assembly while also forming a reverse locking mechanism. This composite structure reduces the probability of sleeve displacement, significantly improving the reliability of insulation protection.

[0015] 2. Improved clamping performance due to hinge optimization: The innovative layout of placing the rivets on the side of the hinge base away from the clamping head creates a leverage amplification effect during clamping. Compared with traditional center hinges, this design increases the interlocking contact area, and the three-point positioning structure formed by the toothed protrusions at the gripper effectively prevents the battery terminals from slipping.

[0016] 3. Enhanced stability and safety: The horizontal anti-slip texture on the inner side of the fully enclosed second socket creates a directional friction coefficient difference, ensuring sufficient anti-slip properties without affecting opening and closing operations. Combined with the design of the wire sheath and crimping structure, a complete current path protection is formed.

[0017] 4. Innovative Maintenance Convenience: The modular socket structure, combined with a precise opening guide design, makes it easy to replace the insulating sleeve while greatly reducing maintenance costs.

[0018] The systematic integration of the above innovative elements enables this charging clip to maintain the conductivity of traditional products while reducing the risk of insulation failure. It is particularly suitable for automotive repair work environments with high humidity and high oil content, and has significant technological advancements. Attached Figure Description

[0024] The following detailed description illustrates the specific implementation method:

[0025] Example 1

[0026] like Figure 1-4 As shown in the figure, this embodiment illustrates a charging clip, including a pair of upper metal clips 1 and lower metal clips 2 that are hinged to each other, the upper metal clips 1 and lower metal clips 2 forming a clip-type conductor.

[0027] In this embodiment, both the upper metal clamp 1 and the lower metal clamp 2 include a clamping head 3 and a handle 4. The clamping head 3 is used to clamp objects, and the handle 4 is used to grip. A torsion spring is built into the hinge of the upper metal clamp 1 and the lower metal clamp 2 to provide elastic return force. Both the upper metal clamp 1 and the lower metal clamp 2 are fitted with matching insulating sleeves 5. The insulating sleeve 5 includes a semi-enclosed first sleeve 51 connected to the clamping head 3 and a fully enclosed second sleeve 52 connected to the handle 4. The handle 4 of both the upper metal clamp 1 and the lower metal clamp 2 is provided with reverse teeth 41. The reverse teeth 41 are set at an angle from the handle 4 toward the clamping head 3. During installation, the handle 4 is fully inserted into the fully enclosed second sleeve 52 through the opening of the semi-enclosed first sleeve 51.

[0028] Specifically, the combination structure of the semi-enclosed first socket 51 and the fully enclosed second socket 52, combined with the reverse tooth 41 design on the inner side of the handle part 4, achieves a triple protection effect: First, the semi-enclosed structure forms a precise limit at the clamping head 3, preventing the sheath from moving forward and causing incomplete coverage of the clamping surface; second, the fully enclosed structure completely covers the conductive area of ​​the handle part 4, eliminating the risk of axial movement in traditional simple socketing; finally, the inclined orientation design of the reverse tooth 41 causes the sheath to generate a one-way locking effect during insertion, ensuring both assembly convenience and forming a reverse locking mechanism.

[0029] Example 2

[0030] like Figure 1-4 As shown, another embodiment illustrates a charging clip based on embodiment 1. Further explanation is provided in a further possible implementation of this embodiment, such as... Figure 2-3 As shown, the upper metal clamp 1 includes a first semi-circular hinge seat 11 disposed at the hinge joint between the upper metal clamp 1 and the lower metal clamp 2; the lower metal clamp 2 includes a second semi-circular hinge seat 21 disposed at the hinge joint between the upper metal clamp 1 and the lower metal clamp 2; the first semi-circular hinge seat 11 and the second semi-circular hinge seat 21 are hinged together by a rivet 6; the rivet 6 is disposed on the side of both the first semi-circular hinge seat 11 and the second semi-circular hinge seat 21 away from the clamping head 3. With the hinge position of the rivet 6 shifted rearward, the contact area between the clamping head 3 and the clamped object increases when clamping an object.

[0031] Specifically, the innovative layout of the rivet 6 being located on the side of the hinge seat away from the clamping head 3 creates a lever amplification effect during clamping, increasing the contact area.

[0032] To further explain, in some other possible implementations of this embodiment, such as Figure 4 As shown, the clamping head 3 includes a biting tooth portion 31 and a tiger mouth portion 32; the tiger mouth portion 32 is provided with a tooth-shaped protrusion 321, which makes the clamping more stable.

[0033] Example 3

[0034] like Figure 1-4 As shown, another embodiment demonstrates a charging clip based on embodiment 1. In this embodiment, both the upper metal clip 1 and the lower metal clip 2 have wire connection portions 42 at their handle portions 4 to facilitate wire connection.

[0035] To further explain, in a further possible embodiment of this embodiment, the end of the fully enclosed second socket 52 of the insulating sleeve 5 is provided with a wire sheath 53 that matches the wire connection portion 42. When connecting, after the wire passes through the sheath, it is electrically crimped with the wire connection portion 42. The wire connection portion 42 protected by the wire sheath 53 is not easy to bend during use, effectively extending its service life.

[0036] Furthermore, in these embodiments, the inner side of the fully enclosed second socket portion 52 of the insulating sleeve 5 is provided with horizontal anti-slip texture 521 to ensure sufficient anti-slip properties when gripping without affecting the opening and closing operation.

[0037] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
