Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a female double-wire clamp. Background Technology

[0002] In power systems, whether it's indoor distribution box wiring or outdoor transmission line branch connections, double female clamps can be used to connect two power lines, ensuring that current can be stably transmitted from one conductor to another, achieving efficient power distribution. A double female clamp is an electrical connection device used to connect and fix two conductors. One end (the female part) is usually designed with a structure that can receive and clamp the conductors, mainly used to achieve a stable electrical connection between two conductors and other electrical equipment or lines.

[0003] However, existing female double-ended clamps are often complex in structure, and the installation and disassembly process is relatively cumbersome. This not only affects work efficiency but may also lead to unstable connections, loosening, poor contact, and other problems, thereby affecting the quality and safety of power transmission. To address the above issues, this utility model proposes a female double-ended clamp. Utility Model Content

[0004] The present invention aims to solve the technical problems mentioned in the background art and provide a female double wire clamp.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a female double wire clamp, comprising a female body, which includes a plastic block coated with rubber, a positive terminal plate, a negative terminal plate, and a terminal. The positive terminal plate and the negative terminal plate are disposed at opposite intervals at both ends of the plastic block. The terminal is located outside the plastic block and is integrally formed with the positive terminal plate. Two clamping plates are fixedly connected to both the positive terminal plate and the negative terminal plate to form a clamping structure that can clamp the wire.

[0006] A copper tube is sleeved and fixedly connected to the outside of the female connector body. The copper tube is a hollow structure with openings at both ends. A spring piece that abuts against the copper tube is integrally formed on the negative terminal plate. A spring ring that is fixedly connected to the plastic block is fitted inside the copper tube. The terminal is located inside the spring ring.

[0007] A further preferred embodiment: a groove is formed on the plastic block to connect with the copper tube, and the copper tube has a cylindrical structure.

[0008] A further preferred embodiment: a limiting ring is fixedly connected to the end of the copper tube away from the plastic block, and the spring ring is positioned on the limiting ring.

[0009] A further preferred embodiment: the spring ring includes two integrally formed fixing rings and multiple limiting plates, the multiple limiting plates are fixedly connected between the two fixing rings, the multiple limiting plates are spaced apart along the circumference of the fixing rings, and there is a gap between adjacent limiting plates.

[0010] A further preferred embodiment: the limiting plate is an arc-shaped structure that protrudes towards the axis of the fixed ring, so that a pair of male connecting ends are formed between multiple limiting plates for clamping.

[0011] A further preferred embodiment: the positive electrode plate, the negative electrode plate, the terminal and the spring coil are preferably made of copper.

[0012] Beneficial effects:

[0013] 1. By setting up clamping plates, copper tubes, and spring clips, the clamping plates facilitate quick clamping and positioning of wires, improving the efficiency of wire assembly and disassembly and the overall work efficiency, and avoiding unstable connections, loosening, poor contact, and other issues.

[0014] 2. The spring ring facilitates the connection between the female connector and the external male connector, making the connection more stable and reducing electrical faults caused by loose connections.

[0015] 3. By setting a limiting ring and a groove, the copper tube can be tightly fitted onto the outside of the plastic block through the groove. The cylindrical structure of the copper tube matches the shape of the groove. This fit helps to easily fit the copper tube onto the plastic block during installation and ensures a firm connection between the copper tube and the plastic block. The spring ring inside the copper tube plays a role in positioning and clamping, and the limiting ring prevents the spring ring from coming out of the copper tube, ensuring the stability of the spring ring's position.

[0022] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0023] Please see Figure 1-5 In this embodiment of the utility model, a female double wire clamp includes a female body, which includes a plastic block 2 coated with rubber, a positive terminal plate 5, a negative terminal plate 3, and a terminal 6. The positive terminal plate 5 and the negative terminal plate 3 are arranged at opposite intervals at both ends of the plastic block 2. The terminal 6 is located outside the plastic block 2 and is integrally formed with the positive terminal plate 5. Two clamping plates 4 are fixedly connected to the positive terminal plate 5 and the negative terminal plate 3 to form a clamping structure that can clamp the wire. A copper tube 1 is sleeved and fixedly connected to the outside of the female body. The copper tube 1 is a hollow structure with openings through both ends. A spring piece 9 that abuts against the copper tube 1 is integrally formed on the negative terminal plate 3. A spring ring 7 that is fixedly connected to the plastic block 2 is attached to the inside of the copper tube 1. The terminal 6 is located inside the spring ring 7.

[0024] Specifically, the female connector double wire clamp primarily achieves electrical connection through metal-to-metal contact. When two wires need to be connected to the positive terminal plate 5 and negative terminal plate 3 on the female connector body respectively, the wires are clamped and fixed by the clamping structure formed by the positive terminal plate 5 and negative terminal plate 3 and the clamping plates 4 on them. That is, by placing the two wires on the positive terminal plate 5 and negative terminal plate 3 respectively, and then pressing the two clamping plates 4 on them to clamp the wires, the clamping plates 4 will fit tightly against the outer surface of the wires, thereby achieving electrical connection between the wires and the female connector body. This connection method can effectively reduce contact resistance and reduce electrical leakage. It can reduce losses during transmission and ensure the accuracy of signal transmission. After the wire is connected to the positive terminal 5 and the negative terminal 3, the positive terminal 5 is connected to the terminal 6, and the negative terminal 3 is connected to the copper tube 1 through the spring 9. Each of them forms a current-conducting line and does not interfere with each other. This makes it possible to connect the lines of the two by connecting the external male and female connectors. The overall structure and operation steps are simple. The clamping plate 4 facilitates the quick clamping and positioning of the wire, improves the efficiency of wire assembly and disassembly and the overall work efficiency, and avoids unstable connection, loosening and poor contact.

[0025] It should be noted that the plastic block 2 is an insulating material to prevent short circuits between the positive terminal plate 5 and the negative terminal plate 3. The terminal 6 does not contact the spring ring 7. The copper tube 1 is designed to facilitate circuit connection. The spring ring 7 is designed to facilitate the connection between the overall female connector body and the external male connector. The positive terminal plate 5, the negative terminal plate 3, the clamping plate 4, the terminal 6, and the spring 9 are all made of conductive hardware materials.

[0026] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, a groove 10 is formed on the plastic block 2 to connect with the copper tube 1. The copper tube 1 has a cylindrical structure. A limiting ring 11 is fixedly connected to the end of the copper tube 1 away from the plastic block 2. The spring ring 7 is limited on the limiting ring 11. Specifically, the limiting ring 11 is integrally formed with the copper tube 1. The groove 10 on the plastic block 2 matches the copper tube 1, so that the copper tube 1 can be tightly fitted on the outside of the plastic block 2. The cylindrical structure of the copper tube 1 matches the shape of the groove 10. This matching helps to easily fit the copper tube 1 onto the plastic block 2 during installation and ensures a firm connection between the copper tube 1 and the plastic block 2. The spring ring 7 plays a positioning and clamping role inside the copper tube 1. The limiting ring 11 prevents the spring ring 7 from coming out of the copper tube 1 and ensures the stability of the position of the spring ring 7.

[0027] In this embodiment of the utility model, such as Figure 3 As shown, the spring ring 7 includes two integrally formed fixing rings 71 and multiple limiting plates 72. The multiple limiting plates 72 are fixedly connected between the two fixing rings 71. The multiple limiting plates 72 are spaced apart along the circumference of the fixing rings 71, and there is a gap 73 between adjacent limiting plates 72. The limiting plates 72 are arc-shaped structures that bulge towards the axis of the fixing rings 71, so that a pair of male connector ends are clamped together between the multiple limiting plates 72. Specifically, the setting of the spring ring 7 facilitates the connection between the female connector body and the external male connector end, making the connection more stable and reducing electrical faults caused by loose connection.

[0028] In this embodiment of the utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positive terminal plate 5, the negative terminal plate 3, the terminal 6, and the spring ring 7 are preferably made of copper. Specifically, the material properties of copper give the female double wire clamp good electrical and mechanical properties, which can ensure a good electrical connection between the female double wire clamp and the wire and improve the working efficiency of the female double wire clamp.

[0029] Furthermore, in this embodiment, as Figure 5As shown, the entire device is connected by a material strip 8 during production. This is to facilitate the connection of products for making tape packaging and terminal 6. After the terminal 6 is made during production, the material strip 8 will be cut off. The technology for producing the female head body, spring ring 7 and copper tube 1 is existing technology.

[0030] Working Principle: The female double wire clamp achieves electrical connection primarily through metal-to-metal contact. When two wires need to be connected to the positive terminal plate 5 and negative terminal plate 3 on the female connector body, respectively, the clamping structure formed by the positive terminal plate 5 and negative terminal plate 3 and the clamping plates 4 on them clamps and fixes the wires. Specifically, by placing the two wires on the positive terminal plate 5 and negative terminal plate 3 respectively, and then pressing down on the two clamping plates 4, the wires are clamped tightly, ensuring the clamping plates 4 fit snugly against the outer surface of the wires. This achieves electrical connection between the wires and the female connector body. This connection method effectively reduces contact resistance and minimizes... To minimize energy loss during transmission and ensure accurate signal transmission, after connecting the wires to the positive terminal 5 and the negative terminal 3, the positive terminal 5 is connected to the terminal 6, while the negative terminal 3 is connected to the copper tube 1 via the spring 9. Each of the two forms a current-conducting path, without interfering with each other. This allows for the connection of the two circuits by connecting the external male and female connectors. The overall structure and operation steps are simple. The clamping plate 4 facilitates quick clamping and positioning of the wires, improving the efficiency of wire assembly and disassembly and the overall work efficiency, and avoiding unstable connections, loosening, poor contact, and other issues.
