The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not used to limit the utility model. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0031] 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.

[0032] Please refer to Figure 1 The utility model provides a battery clamp with wiring margin, including a jacket 2 and a clamp body 1, the jacket 2 is concavely formed with a receiving groove 21 for installing the clamp body 1, and the rear end face of the receiving groove 21 is provided with a line hole 22 for allowing the conductive line to pass through, the rear end of the clamp body 1 is provided with a wire clamping portion 11 corresponding to the line hole 22, and the bottom surface of the receiving groove 21 is provided with a line groove 23 for accommodating the conductive line, and the line groove 23 is located between the wire clamping portion 11 and the line hole 22, the wire clamping portion 11 includes a circuit base 112 and a pair of mutually matching baffles 111, the circuit base 112 is connected to the clamp body 1, the baffle 111 is bent and connected above the circuit base 112, and the baffle 111 and the circuit base 112 enclose a wire bundle opening 113 for fixing the line.

[0033] Combined with the above structure and process description, it can be seen that in this design, the battery clamp with wiring margin has at least the following beneficial effects: the conductive circuit passes through the circuit hole 22 to press open the baffle 111 and enter the wiring port 113, and the conductive circuit is initially fixed in the vertical direction through the circuit hole 22. Thereafter, the baffle 111 is reset under the action of elasticity, and the conductive circuit is clamped in the vertical direction by the circuit base 112 and the baffle 111. The vertical fixation of the conductive circuit and the prevention of the conductive circuit from falling off are achieved through the clamping part 11. In addition, during the rotation and movement of the clamp body 1, the non-contact circuit hole 22 and the clamping part 11 provide a redundant bending space at the jacket 2. When the circuit hole 22 and the clamping part 11 are fixed at both ends, the conductive circuit between the two ends will not collide and wear the battery clamp. In actual use, it is often affected by various factors, such as frequent plugging and unplugging operations, differences in material expansion and contraction at different ambient temperatures, and possible vibrations and shocks, which may cause the conductive circuit at the connection to become loose or even disconnected. If the conductive clamp 1 of the battery clamp is disconnected from the conductive circuit, the battery clamp's circuit connectivity will be directly affected, not only preventing the battery clamp from functioning properly but also potentially damaging other components in the circuit due to the sudden interruption of current. Furthermore, it may cause safety hazards such as short circuits, sparks, or even fire. The design of the circuit hole 22 and the clamping portion 11 ensure the connection between the conductive clamp 1 and the conductive circuit, effectively resolving the problem of frequent pulling of the conductive circuit in existing battery clamps, which can easily wear out the battery clamp.

[0034] Please refer to Figures 1 to 4In this embodiment, the conductive circuit passes through the circuit hole 22, presses open the baffle 111, and enters the cable opening 113. The baffle 111 then returns to its original position under the action of elasticity, and the end of the conductive circuit is blocked by the opening of the cable opening 113. The conductive circuit is vertically clamped by the circuit base 112 and the baffle 111, and the conductive circuit is fixed by the cable clamping portion 11. The majority of the conductive circuit fixed through the circuit hole 22 is accommodated in the cable groove 23, which not only facilitates the bending of the conductive circuit, but also provides redundant bending space during the rotation and movement of the clamp body 1. When one end is fixed by the cable opening 113, the remaining conductive circuit portion will not collide with each other, causing the clamping portion 11 to loosen. This design achieves a stable fixation of the conductive circuit, effectively solving the problem of unstable conductive circuit connection in existing battery clamps.

[0035] Please refer to Figures 1 to 4 In this embodiment, the shapes of the cable opening 113 include rectangular, oblate and triangular. The cable opening 113 enclosed by the baffle 111 and the circuit base 112 can form cable openings 113 of different shapes in order to adapt to conductive circuits of different thicknesses and shapes. Among them, the rectangular cable opening 113 is easy to process and suitable for most wires; the oblate cable opening 113 has a relatively rounded contour, which can reduce the contact stress with the conductive circuit and reduce the wear on the circuit, and is suitable for clamping highly flexible wires and adaptable scenarios; the three sharp edges of the triangular cable opening 113 can increase the clamping force on the conductive circuit to a certain extent. Of course, there are also cable openings 113 of other shapes, which are not listed here one by one.

[0036] Please refer to Figures 1 to 4 In this embodiment, the edge of the baffle 111 is provided with several wire-pressing serrations 114, which are used to compress the conductive circuit into the cable opening 113. A gap is formed between the wire-pressing serrations 114 provided on the two corresponding baffles 111, allowing the conductive circuit to enter the cable opening 113. This design ensures that the conductive circuit is firmly compressed within the cable opening 113, not only improving the stability of the conductive circuit but also enhancing the clamping effect of the cable opening 113 on the circuit, thereby preventing the circuit from loosening or falling off during vibration or movement. The gap formed is small enough to prevent the circuit from escaping if it is not compressed.

[0037] Please refer to Figure 9 and Figure 10In this embodiment, the shapes of the wire pressing teeth 114 include triangle, rectangle, and arc. The triangular wire pressing teeth 114 have a stable meshing structure, providing greater resistance when the wire moves perpendicular to the end surface of the cable harness opening 113, preventing the wire from escaping the cable harness opening 113. The rectangular wire pressing teeth 114 have a regular geometric shape, straight edges, and are easy to process. Their shape is stable and not easily deformed, and they can provide uniform pressing force. The arc-shaped wire pressing teeth 114 have rounded edges, which can reduce wear and damage to the conductive circuit.

[0038] Please refer to Figure 7 and Figure 8 In this embodiment, a buffer slope 2132 is provided at the junction of the receiving groove 21 and the line groove 23, and the wire clamping portion 11 is located on the side of the buffer slope 2132 away from the line groove 23. The buffer slope 2132 is provided at the junction of the receiving groove 21 and the line groove 23 to reduce friction and stress generated when the line changes direction, thereby protecting the line from damage.

[0039] Please refer to Figures 1 to 7 In this embodiment, the clamp body 1 is provided with a clamping frame 3 for clamping the battery electrode, and the clamping frame 3 is electrically connected to the wire clamping portion 11. The clamp body 1 is provided with a clamping frame 3 for clamping the battery electrode, and the clamping frame 3 is electrically connected to the wire clamping portion 11. This design achieves a stable connection and smooth transmission between the battery electrode and the wire clamping portion 11.

[0040] Please refer to Figures 1 to 10 In this embodiment, the clamping body 1 and the clamping portion 11 are integrally formed. This integral molding reduces the joints and connection points between the components, reduces the risk of failure due to poor or loose connections, and also improves the overall strength and stability of the structure.

[0041] Please refer to Figures 1 to 10 In this embodiment, the clamping body 1 and the wire clamping part 11 are both made of conductive materials. Since both the clamping body 1 and the wire clamping part 11 need to have conductive properties, they are usually made of conductive materials. These materials usually include metals (such as copper, aluminum, stainless steel, etc.), alloys or conductive plastics. Metals are widely used in such structures due to their good conductive properties and mechanical strength. Alloys can optimize conductive properties and mechanical properties by adjusting their composition to meet specific usage requirements. Conductive plastic is a relatively new material that combines the lightweight and easy processing of plastics with the conductive properties of metals, providing more possibilities for the manufacture of the clamping body 1 and the wire clamping part 11.

[0042] Please refer to Figures 2 to 7In this embodiment, the receiving slot 21 includes a rear receiving slot 213, which is provided with a plurality of first support ribs 2131. The first support ribs 2131 are supported on the surface of the clamping body 1. The rear receiving slot 213 is provided with a plurality of first support ribs 2131, which are directly supported on the surface of the clamping body 1. This design provides stable support for the clamping body 1 from the rear, helping to prevent the clamping body 1 from moving backward or tilting during use.

[0043] Please refer to Figures 2 to 7 In this embodiment, the receiving slot 21 includes a middle receiving slot 212, the inner wall of which is provided with positioning ribs 2122 that support the surface of the clamping body 1. The inner wall of the middle receiving slot 212 is provided with positioning ribs 2122, which also support the surface of the clamping body 1. The positioning ribs 2122 not only provide additional support for the clamping body 1, but also serve as a positioning function, ensuring that the position of the clamping body 1 in the middle receiving slot 212 does not shift to the left or right.

[0044] Please refer to Figures 2 to 7 In this embodiment, the middle receiving groove 212 is provided with a second support bone 2121 that supports the surface of the clamp body 1. The middle receiving groove 212 is located near the fulcrum of the battery clamp, where shear force is relatively large. The second support bone 2121 is provided here to further strengthen the support and fixation of the clamp body 1 and prevent excessive shear force from causing wear on the clamp body 1 and the jacket 2.

[0045] Please refer to Figures 2 to 7 In this embodiment, the receiving slot 21 includes a front receiving slot 211, the bottom surface of which is provided with a plurality of third support ribs 2111 that support the surface of the clamping body 1. The stress on the front receiving slot 211 near the clamping electrode is relatively high. Therefore, the bottom surface of the front receiving slot 211 is provided with a plurality of third support ribs 2111, which support the bottom (or front) surface of the clamping body 1. This design provides support for the clamping body 1 from the front, and together with other supporting structures in the front (such as the first support rib 2131 of the rear receiving slot 213 and the positioning rib 2122 / second support rib 2121 of the middle receiving slot 212), it forms a complete support system.

[0046] The utility model also provides a battery connection device, including a conductive lead and a battery clamp with wiring margin, the conductive lead passes through the circuit hole 22, the conductive lead is received in the circuit groove 23, and the conductive lead is fixed in the wire clamping part 11.
