Abstract
Description
Technical Field
[0001] The present application relates to the technical field of connectors, and in particular to an enameled wire ICD piercing terminal. Background Art
[0002] When the enameled wire is connected to the circuit, it is necessary to pre-treat the enameled wire. Since the outer layer of the enameled wire is coated with insulating paint, the insulating paint of the part to be welded needs to be removed before welding to expose the conductor inside. This can usually be done by scraping or using a special paint removal tool. Make sure that the length of the paint layer removed is sufficient to form a stable welding point, followed by the welding process. Tools such as electric soldering irons or hot air guns can be used to heat and melt the solder, and then the molten solder is applied to the exposed part of the enameled wire and the circuit board to be connected. During the welding process, it is necessary to pay attention to controlling the welding time and temperature to avoid excessive temperature from causing damage to the enameled wire or circuit board. At the same time, ensure that the solder fully penetrates the contact surface of the enameled wire and the circuit board to form a firm connection.
[0003] The whole process is very complicated, and when soldering, the insulating layer on the outside of the enameled wire must be completely cleaned and not processed too much, otherwise cold solder joints will occur, thus affecting the reliability of the entire circuit. In the prior art, the enameled wire is fixed directly through the terminal, but the insulating layer on the outside of the enameled wire still needs to be processed before the fixation can be completed. Therefore, an enameled wire ICD piercing terminal is required. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of the present application is to provide an enameled wire ICD piercing terminal to solve the technical problem that the insulator on the outside of the enameled wire cannot be removed at one time.
[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an enameled wire ICD piercing terminal, comprising a piercing blade and a plastic part of a connecting end, wherein the piercing blade is integrally formed, and the piercing blade comprises two symmetrical blades, wherein there is a gap between the two symmetrical blades, and the gap between the symmetrical blades is smaller than the diameter of a standard wire.
[0006] By adopting the above technical solution, the enameled wire is aligned with the middle position of the symmetrical blades, and by pressing, the insulating layer on the outside of the enameled wire is cut by the inside of the symmetrical blades, so that the piercing blades are in contact with the conductors in the enameled wire, making the entire piercing blade a metal conductor. At the same time, the piercing blades only pierce the insulating layer at the position where they contact the conductor, thereby ensuring its reliability.
[0007] Furthermore, fixed barbs are provided on both sides of the two symmetrical blades, and the fixed barbs include upper barbs and lower barbs. The width of the upper barbs is greater than the width of the lower barbs. The upper barbs are located at the upper ends of the lower barbs.
[0008] By adopting the above technical solution, when the piercing blade is inserted into the plastic part, the upper barbs and the lower barbs on both sides will be quickly inserted into the plastic part along the side wall of the plastic part, making it more convenient to complete the piercing. At the same time, when the piercing blade is inserted into the plastic part, the trapezoidal arrangement of the upper barbs and the lower barbs can resist the two sides to increase the supporting force.
[0009] Furthermore, an inclined portion is provided at the bottom of one end of the two symmetrical blades close to each other, and the two inclined portions are in an eight-shaped shape.
[0010] By adopting the above technical solution, the inclined arrangement of the two sides of the symmetrical blade can more conveniently slide the two sides of the enameled wire into the gap therebetween.
[0011] Furthermore, a limiting portion is provided at the upper end of the symmetrical blade.
[0012] By adopting the above technical solution, the setting of the limit block can ensure that the conductor in the enameled wire will not be affected due to excessive force when inserting the terminal.
[0013] Furthermore, a connecting portion is provided between the limiting portion and the symmetrical blade, and a width of the connecting portion is smaller than a width of the apex of the barbs on both sides.
[0014] By adopting the above technical solution, when the symmetrical blade completely pierces the enameled wire and is fixed, the upper barb can increase its holding force.
[0015] Furthermore, a conductive block is fixedly disposed on the limiting portion.
[0016] By adopting the above technical solution, the wire strips are used to achieve electrical connection. They pierce the insulation layer of the wires to ensure that the current can flow smoothly between the various components, thereby realizing the function of the circuit. This connection method not only simplifies the connection steps, but also improves the reliability and stability of the connection.
[0017] Furthermore, the piercing blade is made of conductive material.
[0018] By adopting the above technical solution, the piercing blade becomes a conductor directly after piercing, thereby eliminating the soldering process.
[0019] Furthermore, a plurality of piercing blades are arranged on the limiting portion.
[0020] By adopting the above technical solution, multiple wires can be punctured simultaneously according to different situations.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. The piercing blade and the plastic part for the connecting end are integrally formed. The piercing blade includes two symmetrical blades. There is a gap between the two symmetrical blades. The gap between the symmetrical blades is smaller than the diameter of the standard wire. Align the enameled wire with the middle position of the symmetrical blades. By pressing, the insulating layer on the outside of the enameled wire is cut by the inner side of the symmetrical blades, so that the piercing blades can contact the wire in the enameled wire, making the entire piercing blade a metal conductor. At the same time, the piercing blade only pierces the insulating layer at the position where it contacts the conductor, thereby ensuring its reliability.
[0023] 2. The bottom of the symmetrical blade near one end is inclined, and is inclined from the inside to the outside. The inclined settings on both sides of the symmetrical blade can more conveniently slide the two sides of the enameled wire into the gap therein. A limiting portion is provided at the upper end of the symmetrical blade. The setting of the limiting block can ensure that the conductor in the enameled wire will not be affected by excessive force when inserting the terminal. A connecting portion is provided between the limiting portion and the symmetrical blade. The width of the connecting portion is smaller than the width of the apex of the upper barbs on both sides. When the symmetrical blade completely pierces the enameled wire and is fixed, the upper barbs can increase its holding force.
[0024] 3. The limiting part is fixed with a conductive block, and the wire strip is used to realize the electrical connection. They pierce the insulation layer of the wire to ensure that the current can flow smoothly between the various components, thereby realizing the function of the circuit. This connection method not only simplifies the connection steps, but also improves the reliability and stability of the connection. The piercing blade is made of conductive material. After the piercing blade is completed, it directly becomes a conductor, thereby eliminating the soldering process. Multiple piercing blades can be set on the limiting part, and multiple wires can be pierced at the same time according to different situations. BRIEF DESCRIPTION OF THE DRAWINGS

The piercing blade is integrally formed and comprises two symmetrical blades 2. There is a gap between the two symmetrical blades 2. The gap between the symmetrical blades 2 is smaller than the diameter of a standard wire. The enameled wire is aligned with the middle position of the symmetrical blades 2. By pressing, the insulating layer on the outside of the enameled wire is scratched by the inner side of the symmetrical blades 2, so that the wire in the enameled wire is contacted, making the whole a metal conductor. At the same time, only the insulating layer at the position contacting the conductor is pierced, thereby ensuring its reliability.
[0030] In this embodiment, fixed barbs 3 are provided on both sides of the two symmetrical blades 2, and the fixed barbs 3 include upper barbs 301 and lower barbs 302. The width of the upper barbs 301 is greater than the width of the lower barbs 302. The upper barbs 301 are located at the upper end of the lower barbs 302. When the piercing belt is inserted into the plastic part 1, the upper barbs 301 and the lower barbs 302 on both sides can be quickly inserted into the plastic part 1, so that the piercing can be completed more conveniently, thereby ensuring its reliability.
[0031] In this embodiment, an inclined portion 201 is provided at the bottom of one end of the two symmetrical blades 2 that are close to each other, and the two inclined portions 201 are in an eight-shaped shape. The inclined inner sides of the symmetrical blades 2 can more conveniently slide the two sides of the enameled wire into the gap therein.

The setting of the limiting block can ensure that the conductor in the enameled wire will not be affected by excessive force when inserting the terminal. A connecting portion 5 is provided between the limiting portion 4 and the symmetrical blade 2. The width of the connecting portion 5 is smaller than the width of the apex of the upper barbs 301 on both sides. When the symmetrical blade 2 completely pierces the enameled wire and is fixed, the upper barbs 301 can increase its holding force.
[0032] The limiting part 4 is fixed with a conductive block, and the wire strips are used to realize electrical connection. They pierce the insulation layer of the wire to ensure that the current can flow smoothly between the various components, thereby realizing the function of the circuit. This connection method not only simplifies the connection steps, but also improves the reliability and stability of the connection.

A limiting portion 4 is provided at the upper end of the symmetrical blade 2. The setting of the limiting block can ensure that the conductor in the enameled wire will not be affected by excessive force when inserting the terminal.
