[0017] One end of the first arc-shaped portion is fixed to the substrate, the other end of the first arc-shaped portion is connected to one end of the first vertical portion, and the other end of the first vertical portion extends outward along a straight line.

[0018] In one feasible implementation, the sheath crimping claw further includes protrusions;

[0041] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0042] Wire terminals are primarily used to reliably connect wires to electrical equipment, electrical components, or other conductors. They ensure good conductivity and mechanical stability at the connection point, reduce contact resistance, prevent overheating and arcing caused by poor contact, and guarantee the safe and stable operation of the electrical system. Various devices inevitably use a large number of electrical components, which are interconnected through wire harnesses, and these wire harnesses are then connected via connectors.

[0043] Various connectors are interconnected by crimping wires through their matching crimp terminals. When a lead in a terminal needs to be interconnected with multiple other leads, an additional dedicated terminal is required. All the leads to be interconnected are cut and stripped and then crimped together using the dedicated terminal. This method is time-consuming, increases costs, reduces efficiency, and also increases the risk of reliability issues.

[0044] The universal crimping terminal provided in this application can achieve single-wire or multi-wire crimping on the same terminal, effectively replacing the traditional method of using dedicated terminals for multi-wire crimping. This significantly improves production efficiency, enhances terminal versatility, and reduces manufacturing costs.

[0045] The specific structure of the universal wire crimping terminal provided in this application will be described in detail below with reference to the accompanying drawings.

[0046] Reference Figures 1-4 As shown, this application provides a universal crimping terminal, including a substrate 10 and a terminal mating portion 20, a conductor crimping claw 30 and a sheath crimping claw 40 fixed on the substrate 10.

[0047] like Figure 1 and Figure 2 As shown, the substrate 10 can be regarded as a strip structure. In the figure, the length direction of the substrate 10 is the left-right direction, which is the first direction.

[0048] The terminal docking part 20 is fixedly connected to one end of the substrate 10 in the length direction. The wire connection end of the terminal docking part 20 faces the substrate 10, and the terminal connection end of the terminal docking part 20 faces away from the substrate 10.

[0049] The terminal mating part 20 is unchanged from the conventional terminal and has good electrical connection. When the terminal mating part 20 is fixed to the left end of the substrate 10, the wire connection end of the terminal mating part 20 faces the right end and the terminal connection end of the terminal mating part 20 faces the left end so as to connect the wire and the external terminal.

[0050] The conductor crimping claw 30 has the wire insertion direction in the first direction, and the conductor crimping claw 30 is used to crimp the conductor of the wire;

[0051] The wire insertion direction of the sheath crimping claw 40 is the first direction, and the sheath crimping claw 40 is used to crimp the sheath of the wire;

[0052] The sheath crimping claw 40 is provided in multiple ways, and the claw lengths of the multiple sheath crimping claws 40 are different;

[0053] Two or more sheath crimping claws 40, with the copper pieces of each claw being of different lengths. When crimping a single wire, use the shorter crimping claw, and when crimping two or more wires, use the longer crimping claw. This ensures that both single and multiple wires can be crimped securely.

[0054] The universal wire crimping terminal provided in this application has multiple lead sheath crimping claws, which can crimp single or multiple leads. The claws for crimping single leads are shorter, while those for crimping double or multiple leads are longer, ensuring a firm and reliable crimping for both single and multiple leads. After application, the universal wire crimping terminal provided in this application can achieve single or multiple lead crimping functions on the same terminal, effectively replacing the multi-lead crimping function that traditionally required dedicated terminals. This significantly improves production efficiency, enhances terminal versatility, and reduces manufacturing costs.

[0055] Reference Figure 2 and Figure 3 As shown, in some embodiments, the sheath crimping claw 40 includes a first crimping claw and a second crimping claw;

[0056] The first crimping claw and the second crimping claw are both fixed on the substrate 10, and the conductor crimping claw 30, the first crimping claw and the second crimping claw are arranged sequentially along the first direction;

[0057] The length of the first crimping claw is greater than or less than the length of the second crimping claw;

[0058] exist Figure 2 and Figure 3 In the middle, the left sheath crimping claw 40 is the second crimping claw, and the right sheath crimping claw 40 is the first crimping claw. It can be seen that the claw of the first crimping claw is higher than the claw of the second crimping claw. Therefore, the diameter of the ring formed by the first crimping claw is larger than the diameter of the ring formed by the second crimping claw. The first crimping claw can crimp more wires.

[0059] In one embodiment, when crimping 1-3 wires, tools such as wire crimping pliers can be used to bend the second crimping claw, and mechanical pressure can be used to make the second crimping claw tightly connected to the wire; when crimping 3-6 wires, tools such as wire crimping pliers can be used to bend the first crimping claw, and mechanical pressure can be used to make the first crimping claw tightly connected to the wire.

[0060] The universal crimping terminal provided in this application can realize the multi-wire crimping function of the terminal after application. It can replace the original traditional type of crimping terminal, improve the convenience and versatility of wire harness design and manufacturing, and effectively reduce the manufacturing cost of crimping terminal.

[0061] Reference Figure 2 and Figure 3 As shown, in some embodiments, the sheath crimping claw 40 includes a pair of sheath crimping pieces 41, the pair of sheath crimping pieces 41 being symmetrically arranged on both sides of the substrate 10 in the width direction, and the pair of sheath crimping pieces 41 forming an annular structure.

[0062] The length of the sheath clamping piece 41 of the first crimping claw is greater than the length of the sheath clamping piece 41 of the second crimping claw.

[0063] In some embodiments, the sheath clamping piece 41 includes a first arcuate portion 42 and a first vertical portion 43;

[0064] The first arc-shaped portion 42 can be a 1 / 4 arc-shaped plate, and the first vertical portion 43 can be a straight plate. The first arc-shaped portion 42 and the first vertical portion 43 can be an integral structure and can be made of copper. One end of the first arc-shaped portion 42 is fixed on the substrate 10, and the other end of the first arc-shaped portion 42 is connected to one end of the first vertical portion 43. The other end of the first vertical portion 43 extends outward along a straight line.

[0065] In some embodiments, the sheath crimping claw 40 further includes protrusions 44;

[0066] The protrusion 44 can be a circular protrusion, and the protrusion 44 and the sheath clamping piece 41 can be an integral structure. The multiple protrusions 44 are evenly distributed on the opposite surfaces of a pair of sheath clamping pieces 41.

[0067] When the sheath clamping plate 41 clamps the sheath of the conductor, the protrusion 44 can increase the friction between the two, improve the clamping effect, and make the wire clamping more stable.

[0068] Reference Figure 2 As shown, in some embodiments, the edge of the first vertical portion 43 of the first crimping claw is provided with a notch, and the notch extends along the first direction;

[0069] The notch is parallel to the outer end of the first vertical portion 43 of the second crimping claw;

[0070] Figure 2 In the middle, the left sleeve crimping claw 40 is the second crimping claw, and the right sleeve crimping claw 40 is the first crimping claw. The first vertical part 43 of both the second crimping claw and the first crimping claw extends vertically upward. The right end of the first vertical part 43 of the first crimping claw on the right side is provided with a notch, which extends horizontally and is parallel to the top of the first vertical part 43 of the second crimping claw.

[0071] When crimping 1-3 wires, use tools such as wire crimping pliers to make the second crimping claw tightly connected to the wire. At this time, due to the limitation of the claw length, the first crimping claw is not connected to the wire and has no function. At this time, the upper part of the first vertical part 43 of the first crimping claw can be torn off through the notch to shorten the claw of the first crimping claw, so that the lengths of the first crimping claw and the second crimping claw are close, so that the first crimping claw can crimp the wire and improve the stability of the crimping.

[0072] When crimping 3-6 wires, tools such as wire crimping pliers are used to make the first crimping claw tightly connected to the wire. The second crimping claw is limited in length and cannot crimp the wire. However, the horizontal notch on the first crimping claw is small and will not affect the strength of the first crimping claw.

[0073] Reference Figure 2 and Figure 3 As shown, in some embodiments, the conductor crimping claw 30 includes a pair of conductor clamping pieces 31, which are symmetrically arranged on both sides of the substrate 10 in the width direction, and the pair of conductor clamping pieces 31 form an annular structure.

[0074] The conductor clamping piece 31 includes a second arc-shaped portion 32 and a second vertical portion 33;

[0075] The second arc-shaped portion 32 can be a 1 / 4 arc-shaped plate, and the second vertical portion 33 can be a straight plate. The second arc-shaped portion 32 and the second vertical portion 33 can be an integral structure and can be made of copper. One end of the second arc-shaped portion 32 is fixed on the substrate 10, and the other end of the second arc-shaped portion 32 is connected to one end of the second vertical portion 33. The other end of the second vertical portion 33 extends outward along a straight line.

[0076] In some embodiments, the conductor crimping claw 30 further includes a beveled pin 34;

[0077] Multiple oblique nails 34 are evenly fixed on the opposite surfaces of a pair of conductor clamping plates 31. The oblique nails 34 and conductor clamping plates 31 can be an integral structure, and the nail tips of the oblique nails 34 are inclined toward the terminal mating portion 20.

[0078] When in use, the wire is inserted into the conductor crimping claw 30 from right to left. The tip of the angled nail 34 is tilted to the left. The conductor of the wire can be multi-strand copper wire. The tip of the angled nail 34 is inserted into the gap of the multi-strand copper wire. The wire needs to move to the right to detach from the conductor crimping claw 30. The angled nail 34 prevents the wire from moving to the right, thereby improving the stability of the crimping.

[0079] Reference Figures 1-4 As shown, in some embodiments, the universal crimp terminal also includes a conductor crimping assembly 50, which connects the conductor of the wire;

[0080] The conductor crimping assembly 50 includes a sleeve 51, which is fixed on the substrate 10. The open end of the sleeve 51 faces the first direction, and the conductor of the wire is inserted into the sleeve 51.

[0081] The sleeve 51 is a square cylinder, and the two sides of the square cylinder adjacent to the base plate 10 are recessed into the sleeve 51.

[0082] Figure 4 As shown, the bottom end of the square cylinder is connected to the substrate 10, or is part of the substrate 10. Both the left and right sides of the square cylinder are recessed inward. When the conductor crimping assembly 50 is subjected to pressure in the vertical direction, the square cylinder is flattened and clamps the conductor of the wire.

[0083] In some embodiments, the conductor crimping assembly 50 further includes pins 52, and a plurality of pins 52 are uniformly fixed to the inner wall of the sleeve 51;

[0084] The clip 52 and the sleeve 51 can be an integral structure. The tip of the clip 52 faces inward. When the conductor crimping assembly 50 clamps the conductor of the wire, the tip of the clip 52 is inserted into the gap of the multi-strand copper wire, thereby improving the stability of the wire crimping.

[0085] In one embodiment, the main body of the sleeve 51 is made of copper-graphene composite material, the inner wall of the sleeve 51 is provided with a silver plating layer, and the outer wall of the sleeve 51 is provided with a nickel plating layer, thereby ensuring the wire performance.
