Description

Technical Field

[0001] This utility model relates to the field of circuit connection technology, specifically to a piercing terminal structure. Background Technology

[0002] A piercing terminal is an electronic connector, also known as a piercing connector or an insulation displacement connector. It achieves an electrical connection by piercing the insulation layer of the wire with a sharp metal tab, making direct contact with the wire core without the need for wire stripping.

[0003] While existing piercing terminals can solve the problem of non-stripping connections to some extent, they have the following shortcomings: 1. Small contact area: The contact area between the piercing needle and the enameled wire in traditional piercing terminals is limited, which may lead to high contact resistance and affect electrical performance. 2. Inappropriate piercing angle: The piercing angle of traditional piercing terminals is relatively large, which can easily cause damage to the conductive part of the enameled wire during the piercing process, reducing the reliability of the connection. 3. Lack of effective integration with terminal boxes: Traditional piercing terminals are usually used independently and lack optimized integration with terminal boxes, resulting in complex installation and failing to fully utilize the protective and organizational functions of the terminal box. Utility Model Content

[0004] The purpose of this invention is to provide a piercing terminal structure. By bending the main structure to form a U-shaped structure, and then using an elastic component to support the main structure, the corrugated piercing surface on the outer side of the pressure section pierces the connecting wire. The corrugated piercing surface is rectangular, which can ensure a sufficiently large contact area. At the same time, by using the cooperation of the first bending angle and the second bending angle, and by reducing the degree of the second bending angle, the pressure-transformation distance of the main structure is increased, ensuring that the enameled wire is completely pierced, so as to stabilize the circuit connection and solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: piercing the terminal structure, comprising:

[0006] Main structure;

[0007] The main structure includes a wiring segment, a first bend angle, a connecting segment, a second bend angle, and a pressing segment. The first bend angle is located between the wiring segment and the connecting segment. The second bend angle is located on the side of the connecting segment away from the first bend angle. The second bend angle is connected to one side of the pressing segment. The main structure as a whole is a multi-segment bend U-shaped structure.

[0008] The outer side of the pressure line section is provided with a corrugated piercing surface, and the corrugated piercing surface is set in a rectangular shape;

[0009] The main structure also has elastic components inside to provide elastic support for it.

[0010] Preferably, the two sides of the wiring segment have wrapping wings extending outward from the side away from the first bending angle, and the wrapping wings are curved in an arc shape towards the pressing segment.

[0011] Preferably, the wiring segment has barbs extending outward from the side closest to the first bend angle on both sides, and the barbs are arranged in a triangular shape.

[0012] Preferably, the first bending angle is 130-138° and the second bending angle is 42-50°.

[0013] Preferably, multiple sets of limiting blocks are provided on the side of the pressure line segment away from the corrugated puncture surface, and the side of the limiting blocks away from the pressure line segment is inclined, with one end of the elastic member located between the limiting blocks.

[0014] Preferably, a terminal box is provided on the outer side of the main structure, and the wiring segment and the crimping segment are respectively attached to different inner walls of the terminal box.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model connects the wiring segment, connecting segment, and pressure segment through a first bending angle and a second bending angle, making the main structure partially bend and elastic. At the same time, under the support of the elastic component, the corrugated piercing surface on the pressure segment has sufficient contact surface to contact the enameled wire and ensure that the enameled wire is pierced. The optimization of the second bending angle makes the pressure-transformation distance of the main structure inside the terminal box longer, which can prevent thin enameled wires from being unable to be effectively pierced, thus improving the reliability of the wiring terminal.

[0017] 2. This utility model uses a limiting block to conveniently limit the elastic component, preventing it from slipping out of the main structure, and using the elastic component to provide sufficient squeezing force to pierce the enameled wire. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 The piercing terminal structure shown includes:

[0025] Main structure 1;

[0026] The main structure 1 includes a wiring segment 101, a first bend angle 102, a connecting segment 103, a second bend angle 104, and a pressing segment 105. The first bend angle 102 is located between the wiring segment 101 and the connecting segment 103. The second bend angle 104 is located on the side of the connecting segment 103 away from the first bend angle 102. The second bend angle 104 is connected to one side of the pressing segment 105. The main structure 1 as a whole has a multi-segment bend U-shaped structure.

[0027] The outer side of the pressure section 105 is provided with a corrugated piercing surface 2, and the corrugated piercing surface 2 is rectangular in shape.

[0028] The main structure 1 is also equipped with an elastic component 3 for elastic support.

[0029] The wiring segment 101, connecting segment 103, and pressure segment 105 are connected by the first bending angle 102 and the second bending angle 104, so that the main structure 1 is partially bent and elastic. At the same time, under the support of the elastic component 3, the corrugated piercing surface 2 on the pressure segment 105 has sufficient contact surface to contact the enameled wire and ensure that the enameled wire is pierced. The optimization of the second bending angle 104 makes the pressure-transformation distance of the main structure 1 inside the terminal box 7 longer, which can prevent the thin enameled wire from being unable to be effectively pierced and improve the reliability of the wiring terminal.

[0030] Among them, such as Figure 2-3 As shown:

[0031] On both sides of the wiring segment 101, on the side away from the first bending angle 102, there are wrapping wings 4 extending outward. The wrapping wings 4 are curved and bent towards the pressing segment 105. The wrapping wings 4 facilitate the connection and wrapping of the connecting insert through bending and wrapping, thereby improving the stability of the connection between the main structure 1 and the connecting insert.

[0032] Furthermore, such as Figure 2-3 As shown:

[0033] The two sides of the wiring segment 101 have barbs 5 extending outward from the side near the first bending angle 102. The barbs 5 are triangular in shape. The barbs 5 are designed to help the main structure 1 to be inserted into the terminal box 7 and to prevent the main structure 1 from slipping out of the terminal box 7.

[0034] Preferred, such as Figure 1-3 As shown:

[0035] The first bending angle 102 has an angle of 130-138° and the second bending angle 104 has an angle of 42-50°. By limiting the angle of the first bending angle 102, it is prevented from being a right angle, which would increase the pressing distance for thin enameled wires and make it impossible to completely pierce the enameled wire. At the same time, the angle of the second bending angle 104 is limited, which, together with the first bending angle 102, makes the connecting section 103 and the pressing section 105 parallel, which facilitates the fit with the inner wall of the terminal box 7.

[0036] The first bending angle 102 is greater than 90°, which can avoid elastic failure caused by excessive bending. The second bending angle 104 is less than 90°, which can shorten the vertical distance between the pressure segment 105 and the wiring segment 101, adapt to the internal space of the terminal box 7, and at the same time ensure the pressure transformer stroke.

[0037] It is worth noting that, such as Figure 3 As shown:

[0038] Multiple sets of limiting blocks 6 are provided on the side of the pressure section 105 away from the corrugated puncture surface 2. The side of the limiting block 6 away from the pressure section 105 is set at an angle. One end of the elastic component 3 is located between the limiting blocks 6. Through the cooperation of multiple sets of limiting blocks 6, the elastic component 3 can be easily restricted, so that the elastic component 3 can stably support the main structure 1, provide elasticity for outward support of the main structure 1, and prevent the elastic component 3 from falling out of the main structure 1.

[0039] In a further preferred embodiment, such as Figure 4 As shown:

[0040] A terminal box 7 is provided on the outside of the main structure 1. The wiring section 101 and the crimping section 105 are respectively attached to different inner walls of the terminal box 7. The terminal box 7 is designed to facilitate its use with the main structure 1 and can also be used to puncture enameled wires of different diameters, while ensuring the stability of the circuit connection.

[0041] In practical use, the wiring segment 101 of the main structure 1 is brought into contact with the connecting plug, and then the wrapping wing 4 is bent to fix and snap the connecting plug. Then, the elastic member 3 is inserted into the main structure 1 and the end of the elastic member 3 is brought into contact with the inner side of the crimping segment 105, so that one end of the elastic member 3 is located between the limiting blocks 6. The elastic member 3 supports the main structure 1. Then, the enameled wire is placed in the terminal box 7, and then the main structure 1 is inserted into the terminal box 7, so that the corrugated piercing surface 2 on the outside of the crimping segment 105 comes into contact with the enameled wire and pierces the outer skin of the enameled wire to directly contact the internal battery cell. The barbs 5 are snapped into the inside of the terminal box 7 to prevent the main structure 1 from falling out of the terminal box 7.

[0042] The advantages of the piercing terminal structure in this application are:

[0043] Increased contact area design: The ends of the corrugated puncture surface 2 are designed to be flat or beveled, which increases the contact area with the conductive part of the enameled wire, thereby reducing the contact resistance and improving the electrical performance.

[0044] Optimized piercing angle: The piercing angle of the second bending angle 104 has been optimized from a larger angle to a smaller angle, reducing damage to the conductive part of the enameled wire during piercing and improving the reliability of piercing.

[0045] Elastic component 3: disposed between the piercing component and the terminal, it provides elastic support during the piercing process, ensuring that the corrugated piercing surface 2 can make close contact with the enameled wire and maintain stable contact pressure during the connection process.

[0046] The novel piercing terminal and its mating structure with the terminal box of the present invention further improve the flexibility and applicability of the mating between the terminal box 7 and the main structure 1 by increasing the contact between the terminal and the enameled wire.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
