[0001] This utility model relates to the field of power equipment technology, and in particular to a closed pre-insulated wire clamp with temperature measurement function. Background Technology

[0002] Wire clamps are generally used for connecting wires inside or between electrical equipment. For example, wire clamps are used on circuit breakers to connect wires of different specifications, facilitating circuit setup and maintenance. These wire clamps can quickly fix wires to the corresponding terminals, ensuring a good electrical connection, reducing contact resistance, and preventing safety hazards such as overheating caused by poor connections.

[0003] However, in the process of implementing the utility model technical solution in the embodiments of this application, the applicant discovered that the above-mentioned technology has at least the following technical problems:

[0004] Because wire clamps are exposed to the elements for extended periods, they are susceptible to environmental factors, which can easily lead to oxidation and poor contact. Dust and rainwater entering the interior can severely impact the clamp's lifespan. Therefore, it's necessary to protect the internal conductors to prevent external factors from affecting them. Internal corrosion and poor contact can cause temperature increases, necessitating internal temperature monitoring for rapid problem detection. Utility Model Content

[0005] This application provides a closed, pre-insulated wire clamp with temperature measurement function to prevent the conductor from being exposed to the outside environment and affected by the natural environment. This slows down the oxidation of the wire clamp, greatly reduces poor contact caused by conductor oxidation, reduces safety accidents, and effectively improves safety. It can remotely monitor the internal temperature of the wire clamp at any time, and can effectively avoid accidents such as wire clamp burnout and conductor detachment caused by excessive temperature, thus ensuring the safe and stable operation of the power system.

[0006] This application provides a closed, pre-insulated wire clamp with temperature measurement function, comprising: a main wire clamp and an insulating cover. The main wire clamp is disposed inside the insulating cover, and a fixing screw is threaded onto the main wire clamp. The outer end of the fixing screw is provided with the insulating cover, and the other end of the insulating cover is provided with a closed rain cover. A passive temperature sensor is disposed inside the insulating cover, and an insulating layer is provided on the outer side of the insulating cover. One end of the main wire clamp engages with a cable, and the other end engages with a threaded rod on the equipment.

The energy management circuit consists of three parts: a boost circuit, a starting circuit, and a voltage regulator circuit. A current transformer is installed on the boost circuit.

[0008] The open threaded sleeve and cover plate are provided with an assembly groove, which cooperates with the assembly block on the insulating cover. The outer ring of the open threaded sleeve and cover plate is provided with a sealing groove, which cooperates with the protrusion on the insulating cover. A buckle is provided on one side of the cover plate, which is fixed to the insulating cover by the buckle and the groove. The open threaded sleeve and cover plate are made of silicone rubber as a whole, and a seal is formed between the cover plate and the open threaded sleeve and the insulating cover.

[0009] The silicone gel pack is used in conjunction with the torque bolt. When the torque bolt is tightened, the silicone gel pack is subjected to force and automatically fills its interior, wrapping around the entire cable.

[0010] The enclosed rain cover is embedded inside the insulating cover and is connected and fixed to the insulating cover by a snap-fit ​​method. The inner ring of the enclosed rain cover wraps around the fixing screw. The enclosed rain cover is set with color to represent different phases (phase A is yellow, phase B is green, phase C is red, and phase N is blue).

[0011] The insulation layer is made of engineering plastic and silicone rubber. The main body clamp adopts an integrated structure. The main body clamp is completely wrapped with silicone rubber. The overall shape of the main body clamp and the insulating cover is either √-shaped or strip-shaped.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0014] By setting an open threaded sleeve, cover plate and closed rain cover, the main body clamp is enclosed in an insulating cover, which facilitates the tightening of the torque bolt, prevents the conductor from being exposed to the outside and affected by the natural environment, slows down the oxidation of the clamp, greatly reduces poor contact caused by conductor oxidation, reduces safety accidents, and effectively improves safety.

[0015] The cable is wrapped with silicone gel, which effectively prevents water from entering and seals the cable, preventing safety accidents caused by the cable being exposed to the outside and ensuring that the cable is not affected by the environment.

A fixing screw 1 is threadedly provided on the main wire clamp 6. An open threaded sleeve 2 is provided at the outer end of the fixing screw 1. A closed rain cover 9 is provided on the insulating cover 7 at the other end. A passive temperature sensor 8 is disposed inside the insulating cover 7. An insulating layer is provided on the outer side of the insulating cover 7. One end of the main wire clamp 6 is engaged with a cable, and the other end is engaged with a threaded rod on the equipment. The cable is locked and fixed inside the main wire clamp 6 by a torque bolt 3. A silicone gel pack is pre-installed inside the main wire clamp 6. A cover plate 4 is provided on the insulating cover 7 at the torque bolt 3. The cover plate 4 is connected to the insulating cover 7 by an anti-drop device 402. The anti-drop device 402 is connected to the cover plate 4 and the open threaded sleeve 2. The other end of the anti-drop device 402 is connected to the insulating cover 7.

[0025] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0026] By setting up the open threaded sleeve 2, cover plate 4, and closed rain cover 9, the main body clamp 6 is enclosed in the insulating cover 7, which facilitates the tightening of the torque bolt 3, prevents the conductor from being exposed to the outside and affected by the natural environment, slows down the oxidation of the clamp, greatly reduces poor contact caused by conductor oxidation, reduces safety accidents, and effectively improves safety. The cable is wrapped with silicone gel, which can effectively prevent water from entering its interior and effectively seal the cable to prevent safety accidents caused by the cable being exposed to the outside, ensuring that the cable is not affected by the environment. By setting up a passive temperature sensor 8, the internal temperature can be effectively monitored, and the internal temperature of the clamp can be monitored remotely at any time. This can effectively prevent accidents such as clamp burnout and conductor detachment caused by excessive temperature, ensuring the safe and stable operation of the power system. The drop wire 402 can prevent the cover plate 4 and open threaded sleeve 2 from falling off during operation. Example 2

[0027] A closed, pre-insulated wire clamp with temperature measurement function, wherein the passive temperature sensor 8 is composed of a temperature sensor, a signal conditioning and isolation module, a data processing module, a wireless transmitter, a wireless receiver, and an energy management circuit. The energy management circuit consists of three parts: a boost circuit, a starting circuit, and a voltage regulator circuit. A current transformer is installed on the boost circuit.

[0028] The working principle of the passive temperature sensor 8 in this utility model is as follows: The boost circuit is responsible for installing a current transformer on the high-voltage bus. It utilizes the lower voltage output from the induced current on the secondary side of the transformer to increase the voltage and stores it in a capacitor or rechargeable battery. The starting circuit controls the energy output. When the voltage of the energy storage device rises to the high-voltage threshold, the starting circuit controls the opening of the subsequent circuit, allowing energy to flow to the subsequent stage for use by the subsequent circuits. When the voltage of the energy storage device drops to the low-voltage threshold, the starting circuit controls the shut-off of the subsequent circuit, and the energy storage device continues to store energy, working in a continuous cycle. The data processing module controls the temperature sensor to collect temperature measurement data periodically, and converts the analog signal into a digital signal through the signal conditioning and isolation module, providing it to the data processing module for processing. The data processing module then transmits the processed data through a wireless transmitter, which is received by another module in the temperature monitoring system, a wireless receiver, and uploaded to the terminal for display. Example 3

The open threaded sleeve 2 and the cover plate 4 are made of silicone rubber as a whole, and a seal is formed between the cover plate 4 and the open threaded sleeve 2 and the insulating cover 7.

[0030] The silicone gel pack cooperates with the torque bolt 3. When the torque bolt 3 is tightened, the silicone gel pack is subjected to force and automatically fills the interior to wrap around the entire cable.

[0031] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0032] The exposed conductor can be sealed by the open threaded sleeve 2 and the cover plate 4.

[0033] The silicone gel pack is pre-set inside the cable clamp body. When the torque bolt 3 is tightened, it will break the silicone gel pack, causing the silicone gel inside the pack to wrap around the cable, so that the cable is not exposed. This effectively ensures the safety of the cable and improves its service life.

[0034] The enclosed rain cover 9 is embedded inside the insulating cover 7 and is connected and fixed to the insulating cover 7 by means of a buckle 401. The inner ring of the enclosed rain cover 9 wraps around the fixing screw 1. The enclosed rain cover 9 is set with color to represent different phases (phase A is yellow, phase B is green, phase C is red, and phase N is blue).

[0035] After the wire clamp and circuit breaker are installed, the enclosed rain cover 9 can effectively prevent the entry of rainwater, dust and other foreign objects, reduce the impact of foreign objects, effectively ensure the normal use of the wire clamp, and improve the safety of the wire clamp; the enclosed rain cover 9 is set with color separation, which can quickly and accurately identify different lines and avoid electrical faults caused by wiring errors.
