Abstract
Description
Technical Field
[0001] This application relates to the field of terminal technology, and in particular to cold-pressed terminal structures. Background Technology
[0002] Currently, cold-pressed terminals are electrical connection devices, which are accessory products used to achieve electrical connections. With the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control, the usage of terminal blocks is gradually increasing. With the development of the electrical industry, the application range of terminal blocks is becoming wider and wider, and the types are also increasing.
[0003] The structure of cold-pressed terminals in related technologies mainly includes an insulating sheath and a conductive end set at the end of the insulating sheath. The conductive end needs to be connected and fixed to the external wire. However, when installing cold-pressed terminals on the market, the wire is easily blocked by the tail of the conductive end, which causes the wire to fork and run in the opposite direction, making it difficult to enter the wire, thus causing inconvenience to the wiring work. Utility Model Content
[0004] This application provides a cold-pressed terminal structure that facilitates wire insertion, improves wiring efficiency, and ensures a tight connection between the wire and the conductive terminal.
[0005] The cold-pressed terminal structure provided in this application adopts the following technical solution: A cold-pressed terminal structure includes an insulating sheath and a conductive terminal disposed on the insulating sheath. The conductive terminal includes a plug-in portion. An interconnected plug-in groove and a wire inlet groove are formed inside the insulating sheath, and the plug-in groove and the wire inlet groove are coaxially arranged. The plug-in portion is inserted into the plug-in groove. A constricted portion located between the plug-in groove and the wire inlet groove is integrally formed on the inner sidewall of the insulating sheath. A constricted groove is formed on the central axis of the constricted portion. The inner diameter of the constricted groove is smaller than the inner diameter of the plug-in portion. A guide slope is formed at the connection between the constricted portion and the wire inlet groove, and the guide slope is used to guide the wire to be inserted into the constricted groove.
[0006] Preferably, the inner diameter of the insertion slot is smaller than the inner diameter of the inlet slot.
[0007] Preferably, an annular groove is formed on the outer wall of the insulating sheath, located outside the constricted portion.
[0008] Preferably, the conductive end further includes a connecting portion integrally formed with the plug-in portion; the connecting portion is located outside the insulating sheath, and a pressure plate is bent and formed on the connecting portion.
[0009] Preferably, the connecting part is further provided with reinforcing plates located on both sides of the insertion part, and the reinforcing plates are connected and fixed to the insertion part.
[0010] Preferably, the connecting part is provided with a blocking member, and the blocking member faces the insertion part.
[0011] In summary, this application includes at least one of the following beneficial technical effects: After the wire emerges from the constriction groove, it can be accurately and smoothly inserted into the through hole without being easily obstructed by the connector; this reduces the difficulty of wire pulling, improves wiring efficiency, makes wire insertion easier, and ensures a tight connection between the wire and the conductive end. When the end of the wire comes into contact with the guide ramp, the inclined guide ramp can guide the wire into the constriction groove. Attached Figure Description

[0014] The present application will be further described in detail below with reference to the accompanying drawings.
[0015] This application discloses a cold-pressed terminal structure.
[0016] Reference Figure 1 , Figure 2 The cold-pressed terminal structure includes an insulating sleeve 1 and a conductive terminal 2 disposed on the insulating sleeve 1. The conductive terminal 2 includes a plug-in portion 20. An interconnected plug-in groove 10 and a wire inlet groove 11 are formed inside the insulating sleeve 1, and the plug-in groove 10 and the wire inlet groove 11 are coaxially arranged. The plug-in portion 20 is inserted and fixed in the plug-in groove 10, and the outer side wall of the plug-in portion 20 abuts against the inner side wall of the plug-in groove 10.
[0017] like Figure 1 , Figure 2As shown, the inner wall of the insulating sheath 1 also has an integrally formed constriction portion 3 located between the plug-in slot 10 and the inlet slot 11. A constriction groove 30 is formed on the central axis of the constriction portion 3, which is used for the power supply wire to be inserted from the inlet slot 11 into the plug-in slot 10. The plug-in portion 20 has a through hole 200 coaxially through it for the power supply wire to pass through. The through hole 200 and the constriction groove 30 are coaxially arranged, and the inner diameter of the constriction groove 30 is smaller than the inner diameter of the through hole 200. The wire passing through the constriction groove 30 can be accurately and smoothly inserted into the through hole 200 without being blocked by the plug-in portion 20.
[0018] like Figure 1 , Figure 2 As shown, a guide slope 4 is formed at the connection between the constricted portion 3 and the inlet groove 11. The guide slope 4 is used to guide the wire into the constricted groove 30. The inner diameter of the plug groove 10 is smaller than the inner diameter of the inlet groove 11. The slightly larger inner diameter of the inlet groove 11 facilitates wire insertion, while the slightly smaller inner diameter of the plug groove 10 enhances the compactness of the wire.
[0019] like Figure 1 As shown, an annular groove 5 is formed on the outer wall of the insulating sleeve 1, located outside the constriction portion 3. The annular groove 5 makes it easy for installers to hold and grip the insulating sleeve 1, making it less likely to slip off their hands and facilitating wiring.
[0020] like Figure 2 , Figure 3 As shown, the conductive terminal 2 also includes a connecting portion 21 integrally formed with the insertion portion 20. The connecting portion 21 is located outside the insulating sheath 1. Two pressing plates 22 are bent and formed on the connecting portion 21, and the pressing plates 22 are arranged opposite to each other. Reinforcing plates 23 are also fixedly installed on the connecting portion 21, respectively located on both sides of the insertion portion 20. The reinforcing plates 23 are connected and fixed to the insertion portion 20. A blocking member 24 is fixedly installed on the connecting portion 21, facing the insertion portion 20. When the conductive terminals 2 are inserted into each other, the blocking member 24 is used to limit the maximum insertion distance of the male terminal.
[0021] The implementation principle is as follows: The wire is inserted into the insulating sleeve 1 through the opening of the inlet groove 11. Since the inlet groove 11 is directly opposite the constriction groove 30, the wire can be smoothly inserted into the constriction groove 30. Because the inner diameter of the constriction groove 30 is smaller than the inner diameter of the through hole 200 of the insertion part 20, the wire can be accurately and smoothly inserted into the through hole 200 after passing through the constriction groove 30, without being easily obstructed by the insertion part 20. When the end of the wire contacts the guide slope 4, the inclined guide slope 4 guides the wire into the constriction groove 30, thus reducing the difficulty of threading, improving wiring efficiency, making it easier to thread the wire, and ensuring a tight connection between the wire and the conductive end 2.
[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
