[0002] Battery clamps are key components for connecting batteries to external devices in a variety of applications, including power generation, vehicle maintenance, outdoor adventures, and emergency lighting. Their rational design and ease of use are crucial to ensuring safe and efficient operation. However, existing battery clamp designs often suffer from the problem of users misaligning the clamp's position.

[0003] During the implementation of the present invention, the inventors discovered at least the following problems: Battery clamps typically consist of two independent clips, one for clamping the positive and negative terminals of a battery. Because these clips often have similar appearances and dimensions and lack intuitive up / down direction indicators or locking mechanisms, users can easily confuse the up / down direction when quickly connecting or disconnecting a battery, especially in poor visibility or emergency situations, leading to the clips being incorrectly connected to the battery terminals. This misoperation not only prevents the circuit from closing correctly, affecting the normal operation of the equipment, but also poses a greater risk of safety hazards such as short circuits and electric sparks due to reversed polarity, damaging the equipment and even threatening the safety of the operator.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Please refer to Figure 1 The utility model provides an anti-grip reverse battery clamp, comprising an upper jacket 1 and a lower jacket 2 that cooperate with each other, the upper jacket 1 comprising an upper hand grip 12 for hand gripping, the top surface of the upper hand grip 12 being provided with a first groove 121 for allowing the palm to be buckled, and the top side surface of the upper hand grip 12 being provided with a first incision 122 for allowing the palm to be pressed together; the lower jacket 2 comprising a lower hand grip 22 for hand gripping, the bottom side surface of the lower hand grip 22 being provided with a second incision 222 for allowing four fingers to be gripped together, and the length of the first incision 122 is greater than the length of the second incision 222.

[0037] In the technical solution provided by the present invention, the upper jacket 1 and the lower jacket 2 are made of non-conductive material and are integrally formed to ensure the safety and material strength of the upper and lower jackets 2. When the user holds the battery clamp, the base of his palm is snapped into the first groove 121, the base of his palm is pressed into the first incision 122, and the four fingers together are pressed against the side and bottom of the lower grip 22 and then snapped into the second incision 222. The first groove 121 increases the contact area between the palm and the jacket 1 on the battery clamp. Since the width of the four fingers together is smaller than the width of the base of the palm, the user can quickly sense and adjust the direction of holding the battery clamp according to the length difference between the first incision 122 and the second incision 222 after holding it in reverse. This design is ergonomic, helping users quickly sense and correct incorrect holding postures, effectively reducing safety risks caused by improper operation.

[0038] Please refer to Figures 1 to 4 In this embodiment, the upper jacket 1 includes an upper fulcrum portion 13 connected to the upper grip portion 12. The upper jacket 1 is recessed to form a first receiving slot 11 for mounting the conductive clip 4. The sidewalls of the upper fulcrum portion 13 located within the first receiving slot 11 are provided with reinforcing ribs 5. These ribs 5 support the surface of the conductive clip 4, creating a heat dissipation gap between the conductive clip 4 and the sidewalls of the first receiving slot 11. The conductive clip 4 is used to clamp the battery electrodes and is integrally formed from a conductive material. The upper fulcrum portion 13 is sleeved onto the pivot shaft 3, allowing the upper jacket 1 to rotate about the pivot shaft 3. The lower jacket 2 includes a lower fulcrum portion 23 connected to the lower grip portion 22. The lower jacket 2 is recessed to form a second receiving slot 21 for mounting the conductive clamp 4. The sidewalls of the lower fulcrum portion 23 located within the second receiving slot 21 are provided with reinforcing ribs 5. The ribs 5 support the surface of the conductive clamp 4, creating a heat dissipation gap between the conductive clamp 4 and the sidewalls of the second receiving slot 21. The lower fulcrum portion 23 is sleeved onto the pivot shaft 3, allowing the lower jacket 2 to rotate about the pivot shaft 3 and the upper and lower jackets 2 to close or open about the pivot shaft 3. The ribs 5 serve as additional support structures, significantly improving the overall rigidity and stability of the battery clamp. They effectively disperse the stress and pressure generated on the upper and lower support parts 23 when the conductive clamp 4 clamps the battery, preventing damage to the upper and lower support parts 23; the reinforcing ribs 5 not only strengthen the structure, but also form heat dissipation gaps between them and the conductive clamp 4. These gaps allow air circulation, helping to quickly dissipate the heat generated by the conductive clamp 4 when current passes through, preventing performance degradation or damage due to overheating.

[0039] Please refer to Figures 1 to 4In this embodiment, a curved protrusion 123 is provided at the junction of the sidewall of the upper grip 12 and the upper fulcrum 13. A curved recess 223, whose contour corresponds to the curved protrusion 123, is provided at the junction of the lower grip 22 and the lower fulcrum 23. When the upper grip 12 and the lower grip 22 are brought together, the curved protrusion 123 extends into the curved recess 223. The curved protrusion 123 and the curved recess 223, as cooperating contours, act as a buffer. They mitigate the impact force when the clamp handle closes, preventing noise and potential damage from direct impact.

[0040] Please refer to Figures 1 to 4 In this embodiment, the bottom wall of the first receiving groove 11 is provided with support ribs 6, which support the surface of the conductive clip 4 and form a wear-resistant gap between the bottom wall of the first receiving groove 11 and the conductive clip 4. Alternatively, the bottom wall of the second receiving groove 21 is provided with support ribs 6, which support the surface of the conductive clip 4 and form a wear-resistant gap between the bottom wall of the second receiving groove 21 and the conductive clip 4. The support ribs 6 should be evenly distributed on the bottom wall of the first receiving groove 11 or the second receiving groove 21 to ensure that the conductive clip 4 is firmly supported at the upper support point 13, upper grip 12, lower support point 23, and lower grip 22. The support ribs 6 are located between the bottom wall of the receiving groove and the conductive clip 4, forming a wear-resistant gap. This gap effectively prevents the conductive clip 4 from directly contacting the hard bottom wall of the receiving groove during prolonged use, thereby preventing wear and scratches caused by friction.

[0041] Please refer to Figures 4 to 7 In this embodiment, the first receiving groove 11 is provided with a fixing column 7 connected to the conductive clamp 4, and the supporting bone 6 is connected to the fixing column 7; and / or, the second receiving groove 21 is provided with a fixing column 7 connected to the conductive clamp 4, and the supporting bone 6 is connected to the fixing column 7. The fixing column 7 can pass through the conductive clamp 4 and be connected by screws. This connection method can withstand greater tension and pressure, ensuring that the conductive clamp 4 will not loosen or fall off when clamping the battery. The fixing column 7 is not only used to connect the conductive clamp 4 and the receiving groove, but also provides a support point for the supporting bone 6. The supporting bone 6 is connected to the fixing column 7, so that the supporting bone 6 can be firmly supported on the surface of the conductive clamp 4, forming an anti-wear gap and a stable support. This design further enhances the stability of the conductive clamp 4 in the receiving groove.

[0042] Please refer to Figures 2 to 5In this embodiment, the rear end wall of the lower grip portion 22 is provided with a wire hole 2122 for passing the conductive wire. Wire hole 2122 allows the wire to pass through the lower jacket 2 and connect to the conductive clamp 4, thus completing the electrical connection between the battery clamp and the external power supply wire. This design effectively prevents the wire from being broken by the upper and lower jackets and the two conductive clamps 4.

[0043] Please refer to Figures 2 to 5 In this embodiment, a limiting protrusion 2123 is provided at the top of the wire hole 2122, and a limiting notch 1122 is provided on the rear end wall of the lower grip 22. The limiting notch 1122 mates with the limiting protrusion 2123. The limiting notch 1122 and limiting protrusion 2123 are used to control the travel of the upper grip 12 and lower grip 22 when the user grips them, protecting the conductive circuit from wear and tear caused by long-term gripping and collision.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, a second groove 221 is provided at the bottom of the lower grip portion 22, and the middle parts of the user's four fingers after being put together are gripped and pressed on the second groove 221. The length of the first groove 121 is greater than the length of the second groove 221. The design of the second groove 221 allows the user to naturally press the middle parts of the four fingers after being put together on it. This design conforms to the principles of ergonomics and helps to reduce hand fatigue. Since the width of the four fingers put together is less than the width of the base of the palm, the user can quickly sense and adjust the grip direction of the battery clamp according to the length difference between the first groove 121 and the second groove 221 after gripping the battery clamp, and correct the up and down direction of the battery clamp.

[0045] Please refer to Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, the depth of the first groove 121 is greater than the depth of the second groove 221; and / or the area of ​​the first groove 121 is greater than the area of ​​the second groove 221. The difference in area and depth enhances the user's perception of the up and down gripping direction.

[0046] Please refer to Figure 1 、 Figure 8 、 Figure 9 and Figure 10In this embodiment, a third groove 1121 is provided on the side wall of the upper grip portion 12. The third groove 1121 is used to place the user's thumb. A fourth groove 2121 is provided on the side wall of the lower grip portion 22 corresponding to the third groove 1121. The fourth groove 2121 is used to place four fingers together. The combined use of the third groove 1121 and the fourth groove 2121 works together to improve the user's grip comfort and stability. They provide dedicated placement and support for the thumb and four fingers, and when separately provided on the upper and lower grip portions 22, they can also prevent the edge of the jacket from strangulating the hand and optimize the hand's grip posture and force distribution.

[0047] Please refer to Figure 1 、 Figure 8 、 Figure 9 and Figure 10 In this embodiment, the length of the third groove 1121 is greater than the length of the fourth groove 2121; and / or the depth of the third groove 1121 is greater than the depth of the fourth groove 2121. A deeper or longer third groove 1121 better wraps around the thumb, increasing the contact area between the thumb and the groove, thereby improving grip stability. This design helps reduce the possibility of the thumb slipping or dislodging during operation and enhances the user's perception of the upward and downward gripping direction.

[0048] The utility model also provides a battery connection device, including a pair of conductive leads and the anti-grip reverse battery clamp, one end or both ends of each conductive lead are connected to the anti-grip reverse battery clamp, and the conductive lead passes through the lower jacket 2 and is electrically connected to the conductive clamp body 4.

[0049] The utility model also provides a mobile power supply, including a battery pack, a pair of conductive leads and the anti-grip reverse battery clamp, the conductive leads are electrically connected to the battery pack, one end or both ends of each conductive lead are connected to the anti-grip reverse battery clamp, and the conductive leads pass through the lower jacket 2 and are electrically connected to the conductive clamp body 4.
