AI Technical Summary
Existing terminal temperature sensing and early warning devices are not targeted enough and cannot provide accurate early warnings for individual terminals, posing a safety hazard.
A terminal temperature sensing and early warning device was designed. By setting up components such as a heat-conducting plate, a mercury tank and a top block inside the housing, the thermal expansion effect of mercury is used to drive a touch switch to trigger an alarm bell for early warning. A spring return mechanism is adopted to ensure the pertinence and accuracy of the early warning.
It enables precise temperature warning for individual terminals, improving the targeting and effectiveness of warnings, reducing the possibility of false alarms, and enhancing the safety of the power system.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal temperature warning technology, specifically a terminal temperature sensing and early warning device. Background Technology
[0002] As a key connection component in electrical systems, terminal blocks play an important role in transmitting current and ensuring stable circuit operation. However, during long-term use, due to increased contact resistance caused by oxidation, loosening, overload, or environmental factors such as humidity and high temperature, abnormal temperature rises can easily occur at the connection points. If not detected in time, this may lead to insulation aging, fire, or even equipment damage, posing a serious threat to the safety of the power system. The existing terminal block temperature sensing early warning system provides a single warning for multiple terminals, which is not specific enough and needs to be improved.
[0003] Therefore, it is necessary to design a terminal temperature sensing early warning device that is highly practical and has multiple terminal interfaces for separate warning. Utility Model Content
[0004] The purpose of this invention is to provide a terminal temperature sensing and early warning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a terminal temperature sensing and early warning device, comprising a housing, a plurality of cables arranged on one side of the housing, a plurality of heat-conducting plates arranged inside the housing, the number and position of the heat-conducting plates being adapted to the cables, a plurality of partitions arranged inside the housing, a mercury tank arranged inside the partitions, a top block slidably connected inside the partitions, a fixed base fixedly connected to one side of the housing, an alarm bell arranged on one side of the fixed base, and a touch switch arranged on one side of the fixed base, the touch switch being adapted to the alarm bell.
[0006] According to the above technical solution, a spring is provided between the top block and the touch switch.
[0007] According to the above technical solution, a mercury tank is provided on one side of the partition.
[0008] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0009] (1) By setting up a mercury tank, the cable is connected to the inside of the terminal housing. When the temperature is too high during long-term operation, the mercury placed inside the mercury tank will expand through the heat conduction plate. The increased volume will push the top block to move and press against the touch switch. The touch switch will turn on the alarm bell to warn. Since the heat conduction plate, partition, mercury tank and other components are independent and can be connected and adapted to each cable, it can effectively indicate which part is too hot. It is highly targeted and has a good early warning effect.
[0010] (2) By setting a spring, the spring is installed between the top block and the touch switch. After the temperature drops, the mercury volume decreases, and the top block needs to return to its original position. At this time, since the touch switch will not move, the spring force will make the top block return to its original position. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-4 The present invention provides a technical solution: a terminal temperature sensing and early warning device, comprising a housing 1, a plurality of cables 2 arranged on one side of the housing 1, a plurality of heat-conducting plates 3 arranged inside the housing 1, the number and position of the heat-conducting plates 3 being adapted to the cables 2, a plurality of partitions 8 arranged inside the housing 1, a mercury tank 9 arranged inside the partitions 8, a top block 10 slidably connected inside the partitions 8, a fixed base 4 fixedly connected to one side of the housing 1, an alarm bell 5 arranged on one side of the fixed base 4, and a touch switch 6 arranged on one side of the fixed base 4, the touch switch 6 being adapted to the alarm bell 5.
[0018] Specifically, when the cable 2 is connected to the inside of the terminal housing 1 and the temperature is too high during long-term operation, the mercury placed inside the mercury tank 9 will expand due to the heat conduction of the heat conduction plate 3. The increased volume will push the top block 10 to move and press against the touch switch 6. The touch switch 6 will then open the alarm bell 5 to issue a warning. Since the heat conduction plate 3, the partition plate 8, the mercury tank and other components are independent and compatible with each cable 2, they can effectively indicate which part is too hot, which is highly targeted and has a good warning effect.
[0019] A spring 11 is provided between the top block 10 and the touch switch 6.
[0020] Specifically, the spring 11 is installed between the top block 10 and the touch switch 6. After the temperature drops, the mercury volume decreases, and the top block 10 needs to return to its original position. At this time, since the touch switch will not move, the spring force will cause the top block 10 to return to its original position.
[0021] A mercury tank 7 is provided on one side of the partition 8.
[0022] Specifically, mercury tank 2 7 is used to prevent mercury inside mercury tank 1 9 from being carried out when the top block 10 is displaced.
[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
