A terminal and an enameled wire connecting structure

Abstract

This utility model discloses a connection structure for terminals and enameled wires, relating to the field of conductive component assembly technology. It includes a terminal frame body and connecting components. A winding block is installed on the side of the terminal frame body. The connecting components, used to increase the welding length, are disposed on the side of the terminal frame body, and two sets of connecting components are provided. Each connecting component includes a welding terminal strip and an enameled wire body, with the enameled wire body disposed on the inner side of the welding terminal strip. The welding terminal strip and the terminal frame body form a V-shaped structure. This connection structure for terminals and enameled wires pre-presses the V-shaped terminal structure during welding, allowing the V-shaped terminals to contact before welding. The welding width of the terminal can be designed to be 1.6–2.0 mm, thereby increasing the contact length between the enameled wire and the terminal, increasing the welding length between the terminal and the enameled wire, forming a wider welding process range, and simplifying the inspection of the welding position after welding, thus reducing the product scrap rate.

Description

Technical Field

[0001] This utility model relates to the field of conductive component assembly technology, specifically a connection structure between a terminal and an enameled wire. Background Technology

[0002] The connection structure between terminals and enameled wires is a common assembly method for conductive components in electrical equipment. Its core is to ensure stable mechanical strength, excellent conductivity, and resistance to environmental aging. After the insulation layer of the enameled wire is stripped, the exposed conductor is inserted into the metal sleeve (copper or copper alloy) of the terminal. Mechanical pressure (crimping pliers / crimping molds) deforms the sleeve and tightly engages with the conductor.

[0003] However, existing methods of fixing the enameled wire to the Y-type terminal welding position and using welding equipment to weld the terminal and enameled wire are unreliable. The terminal thickness is small, usually 0.6mm, resulting in a short contact length between the terminal and the copper wire. This limits the range of adjustments to the welding process and makes the terminal prone to misalignment during welding, making welding inspection difficult. Utility Model Content

[0004] The purpose of this invention is to provide a connection structure between a terminal and an enameled wire to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure for a terminal and an enameled wire, comprising a terminal frame body and a connecting component, wherein a winding block is installed on the side of the terminal frame body, and the connecting component for increasing the welding length is disposed on the side of the terminal frame body, and two sets of connecting components are provided, wherein the connecting component comprises a welding terminal strip and an enameled wire body, and the enameled wire body is disposed on the inner side of the welding terminal strip, and the welding terminal strip and the terminal frame body form a V-shaped structure.

[0006] Furthermore, the terminal frame body and the winding block are an integrated structure, and two winding blocks are symmetrically arranged about the vertical central axis of the terminal frame body.

[0007] Furthermore, the lower end of the terminal frame body is connected to an assembly end, and the terminal frame body and the assembly end are an integrated structure.

[0008] Furthermore, the upper end of the terminal frame body is connected to a connecting end, and the terminal frame body, the assembly end, and the connecting end form an H-shape.

[0009] Furthermore, a limiting rectangular groove is provided on the lower side of the connecting end, and the connecting end and the limiting rectangular groove are an integrated structure.

[0010] Furthermore, a limiting groove is formed on the upper side of the connecting end, and the limiting groove is triangular in shape.

[0011] This utility model provides a connection structure for a terminal and an enameled wire, which has the following advantages:

[0012] 1. This utility model forms an H-shaped skeleton by means of a terminal skeleton body, an assembly end, and a connecting end. The winding block ensures that the enameled wire body is correctly oriented and installed on the outside of the skeleton. The enameled wire body is located inside the welding terminal strip of the V-shaped structure. During welding, the terminal V-shaped structure is pre-pressed to allow the V-shaped structure terminals to contact before welding. The welding width of the terminal can be designed to be 1.6 to 2.0 mm, thereby increasing the contact length between the enameled wire and the terminal, increasing the welding length between the terminal and the enameled wire, forming a larger welding process range, and simplifying the inspection of the welding position after welding, thus reducing the scrap rate of the product.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figure 1 and Figure 3As shown, a connection structure for a terminal and an enameled wire includes a terminal frame body 1 and a connecting assembly 3. A winding block 2 is installed on the side of the terminal frame body 1, which ensures that the enameled wire body 302 is correctly oriented and installed on the outside of the frame. The connecting assembly 3, used to increase the welding length, is disposed on the side of the terminal frame body 1, and two sets of the connecting assembly 3 are provided. The connecting assembly 3 includes a welding terminal strip 301 and an enameled wire body 302, and the enameled wire body 302 is disposed on the inner side of the welding terminal strip 301. The enameled wire body 302 is located inside the V-shaped welding terminal strip 301. During welding, the V-shaped structure of the terminal is pre-pressed to allow... The V-shaped structure terminals are contacted before welding. The welding width of the terminals can be designed to be 1.6 to 2.0 mm, thereby increasing the contact length between the enameled wire and the terminal, increasing the welding length between the terminal and the enameled wire, forming a larger welding process range, and simplifying the inspection of the welding position after welding, reducing the product scrap rate. The welding terminal strip 301 and the terminal skeleton body 1 form a V-shaped structure. The terminal skeleton body 1 and the winding block 2 are integrated structures, and the winding block 2 is symmetrically arranged with two pieces about the vertical central axis of the terminal skeleton body 1. The lower end of the terminal skeleton body 1 is connected to the assembly end 4, and the terminal skeleton body 1 and the assembly end 4 are integrated structures.

[0019] like Figure 2 As shown, the upper end of the terminal frame body 1 is connected to the connecting end 5, and the terminal frame body 1, the assembly end 4 and the connecting end 5 form an H-shape. The terminal frame body 1, the assembly end 4 and the connecting end 5 form an H-shaped frame. A limiting rectangular groove 6 is opened on the lower side of the connecting end 5, and the connecting end 5 and the limiting rectangular groove 6 are an integrated structure. A limiting inclined groove 7 is opened on the upper side of the connecting end 5, and the limiting inclined groove 7 is triangular in shape. The limiting rectangular groove 6 and the limiting inclined groove 7 provide more limiting space for the enameled wire body 302.

[0020] In summary, the connection structure between this terminal and the enameled wire is first based on... Figures 1-3 The structure shown in the diagram forms an H-shaped skeleton consisting of the terminal frame body 1, the assembly end 4, and the connecting end 5. The enameled wire body 302 is then wound around the outside of the winding block 2 and the skeleton. The winding block 2 ensures the enameled wire body 302 is correctly positioned and installed outside the skeleton. During installation, the enameled wire body 302 is placed inside the V-shaped welding terminal strip 301. During welding, the V-shaped terminal structure is pre-pressed to allow contact before welding. The welding width of the terminal can be designed to be 1.6–2.0 mm, thereby increasing the contact length between the enameled wire and the terminal, increasing the welding length between the terminal and the enameled wire, creating a wider welding process range, simplifying the inspection of the welding position after welding, and reducing the product scrap rate.
