Description

Technical Field

[0001] This utility model relates to the field of cable outlet technology, and specifically to a cable outlet with a stable connection. Background Technology

[0002] Torque terminal type lead-out rods are special electrical connection components typically used in power distribution systems, switchgear, transformers, or high-current connections. Their core feature is the use of torque control technology to ensure the reliability and stability of the wire connection. They are generally made of copper or copper alloys, and may be tin-plated / silvered to enhance conductivity and oxidation resistance. They employ a torque screw or crimp design to ensure that the wire crimping force meets standards.

[0003] Existing torque terminal type cable outlet rods typically secure the wires by tightening bolts on the conduit body during wiring. However, tightening the wires with bolts results in uneven clamping force. Areas with insufficient pressure can form high-resistance points, leading to localized overheating (potentially creating dangerous hot spots). Current will concentrate in areas of high pressure, accelerating material aging in those areas. Furthermore, areas with uneven pressure are prone to fretting wear and plating wear under vibration, causing loosening between the wires and the conduit body, reducing connection stability. Over long-term use, the resistance value may fluctuate and increase.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0005] The present invention provides a wire outlet rod with stable wiring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A securely connected cable outlet includes a cable conduit body. One end of the cable conduit body has a connecting portion. The inside of the cable conduit body has a cable receiving cavity. A pressure plate is movably disposed within the cable receiving cavity. Guide grooves are formed on both sides of the bottom of the inner wall of the cable receiving cavity. Guide blocks that cooperate with the guide grooves are provided on both sides of the pressure plate. A locking hole one and a locking hole two are provided through the top surface of the cable conduit body. The locking hole one and the locking hole two are staggered. A locking bolt is threaded into both the locking hole one and the locking hole two. The threaded end of the locking bolt abuts against both sides of the top of the pressure plate.

[0008] Preferably, the pressure plate is an arc-shaped structure, and both the inner surface of the pressure plate and the bottom surface of the inner wall of the wire cavity are provided with anti-slip texture.

[0009] Preferably, both the inner wall of the guide groove and the outer wall of the guide block have an arc surface structure.

[0010] Beneficial effects

[0011] The above-mentioned technical solutions of one or more of the wire-out rods with stable wiring provided in this utility model embodiment have at least one of the following technical effects:

[0012] This utility model, through the above-described technical solution, tightens the locking bolt to press the wire into the wire cavity, resulting in a more uniform clamping force on the wire, increasing the contact area between the wire and the conduit body, ensuring uniform contact, reducing heat generation, and minimizing contact resistance fluctuations. Furthermore, the cooperation between the guide groove and the guide block causes the wire clamp to deform inward and collapse when the locking bolt presses the wire clamp, resulting in a tighter clamping of the wire and a more secure fixation of the wire. This reduces the risk of loosening due to vibration, temperature changes, or external forces, making the fixation of the wire more stable. Attached Figure Description

[0023] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0024] like Figure 1-5 As shown, it is a structural schematic diagram of a wire-out rod with stable wiring according to a preferred embodiment of the present invention.

[0025] In this embodiment, a connector body 1 is included. One end of the connector body 1 is integrally provided with a connecting part 2 for connection to a device. The connector body 1 has a wire-receiving cavity 3, which is a cylindrical cavity. A wire-pressing plate 4, made of copper, is movably disposed within the wire-receiving cavity 3. During use, a wire 11 is inserted into the wire-receiving cavity 3, with the wire 11 located between the bottom wall of the wire-receiving cavity 3 and the wire-pressing plate 4. Guide grooves 5 are provided on both sides of the bottom of the inner wall of the wire-receiving cavity 3. Guide blocks 6, matching the guide grooves 5, are provided on both sides of the wire-pressing plate 4. A locking hole 7 and a locking hole 8 are provided through the top surface of the connector body 1, staggered from each other. The device is equipped with a locking bolt 9 with an internal thread. The threaded end of the locking bolt 9 abuts against both sides of the top of the pressure plate 4. By tightening the locking bolt 9, the locking bolt 9 pushes the pressure plate 4, causing the pressure plate 4 to press the wire 11 into the wire cavity 3. This makes the clamping force on the wire 11 more uniform, increases the contact area between the wire 11 and the connector body 1, makes the contact more uniform, reduces heat generation, and reduces contact resistance fluctuations. Furthermore, through the cooperation of the guide groove 5 and the guide block 6, when the locking bolt 9 presses the pressure plate 4, the pressure plate 4 deforms inward and collapses and tightens, making the clamping of the wire 11 tighter and more securely fixing the wire 11. This reduces the risk of loosening due to vibration, temperature changes, or external forces, making the fixing of the wire 11 more stable.

[0026] In this embodiment, the pressure plate 4 is designed with an arc shape, which allows it to better fit the shape of the wire 11. The inner surface of the pressure plate 4 and the bottom surface of the inner wall of the wire cavity 3 are provided with anti-slip textures 10. The anti-slip textures 10 increase the friction between the pressure plate 4 and the wire cavity 3, thereby strengthening the fixing effect on the wire 11.

[0027] In this embodiment, both the inner wall of the guide groove 5 and the outer wall of the guide block 6 are arc-shaped structures. This structure allows the outer wall of the guide block 6 to fit perfectly with the inner wall of the guide groove 5. When the locking bolt 9 is tightened, the locking bolt 9 pushes the pressure plate 4 to move downward and press the wire. The guide blocks 6 on both sides of the pressure plate 4 move downward along the guide groove 5. The arc-shaped structure causes the guide blocks 6 on both sides to apply pressure inward, causing the center of the arc-shaped part of the pressure plate 4 to deform and bend inward, thus wrapping and pressing the wire 11 inside the wire cavity 3, resulting in a better pressing effect and tighter clamping.

[0028] The present invention provides a stable wiring outlet rod. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0029] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
