Description

Technical Field

[0001] The utility model relates to the electrical field, in particular to a busbar temperature compensator. Background Art

[0002] With the continuous expansion of the use field of busbars, the use environment and temperature difference of busbars are also gradually expanding, and the corresponding impact on the thermal expansion and contraction of busbars is also getting bigger and bigger. This requires the busbar temperature compensator to have a larger expansion amount. Its main function is to prevent the deformation caused by thermal expansion and contraction of busbar conductors due to seasonal changes. If the busbar is installed in summer, the expansion joint should be opened wider, because the busbar is in the thermal expansion stage in that season; for winter safety busbars, the expansion joint should be opened shorter, because the busbar is in the cold contraction stage in winter.

[0003] When the transmission rail expands and contracts due to temperature changes, the busbar temperature compensator adjusts the gap to avoid deformation of the transmission rail. When the existing compensator performs expansion and contraction compensation due to temperature changes, the activity trajectory is unstable and the accuracy is poor. The fixed seat and the sliding seat will deviate during the movement, hindering the extension and retraction, which needs to be improved. Utility Model Content

[0004] The utility model aims to provide a busbar temperature compensator for the temperature of an active track in view of the above problems.

[0005] In order to achieve the above-mentioned purpose, the utility model discloses a busbar temperature compensator, including a fixed seat and a sliding seat, and its structural features are: a first plug-in row is installed on the fixed seat, and a second plug-in row is installed on the sliding seat, the first plug-in row and the second plug-in row are plugged into each other and the two are slidably matched, a guide rod is fixed on the fixed seat, a guide hole is provided in the sliding seat, the guide rod is inserted in the guide hole, and the guide rod and the guide hole are slidably matched to implement limit guidance for the first plug-in row and the second plug-in row.

[0006] The main structure of the busbar temperature compensator is realized by the combination of the fixed seat and the sliding seat. This design allows the busbar temperature compensator to be adjusted by moving the sliding seat when necessary to adapt to different temperature compensation requirements. The first plug-in row and the second plug-in row slide relative to each other when necessary, thereby changing the contact area or contact position between the two to achieve temperature compensation. The sliding fit ensures smooth movement between the two and is easy to control. The fit of the guide rod and the guide hole ensures the stability and accuracy of the sliding seat during movement. The guide rod not only limits the movement trajectory of the sliding seat, but also increases the stability of the structure, preventing the sliding seat from offsetting or shaking during movement.

[0007] The first plug row includes a plurality of plug boards, and the plurality of plug boards are spaced apart from each other. The design of the plug boards enables a plurality of contact points to be formed between the first plug row and the second plug row, thereby increasing the accuracy and reliability of temperature compensation.

[0008] A pad is provided at one end of the plug board close to the first plug row, and a plurality of pads are provided, and the plurality of pads are installed in the intervals between the plug boards. The pads are installed in the intervals between the plug boards, which can reduce the friction between the plug boards, increase the contact area, and improve the heat conduction efficiency.

[0009] The material of the backing plate is aluminum. As a good thermal conductive material, aluminum can quickly transfer temperature changes to the plug-in board, thereby achieving rapid temperature compensation. In addition, aluminum also has good corrosion resistance, which can extend the service life of the busbar temperature compensator.

[0010] The second plug-in row has the same structure as the first plug-in row, and the plug-in boards on the first plug-in row are inserted into the plug-in board intervals of the second plug-in row.

[0011] The first plug row and the second plug row are both provided with guide holes, the two guide holes partially overlap, a guide shaft is inserted into the guide hole, the guide shaft passes through the guide hole and slides with the guide hole. The cooperation between the guide hole and the guide shaft further enhances the stability of the sliding seat during movement.

[0012] The guide hole is an oblong hole. The design of the oblong hole allows the guide shaft to have a certain range of movement in the guide hole, which to a certain extent increases the flexibility of the sliding seat during movement, allowing it to adapt to fine-tuning requirements in different directions.

[0013] The first plug row and the second plug row are both provided with two guide holes, and the positions of the guide holes on the first plug row and the second plug row correspond to each other. The guide shaft limits the movement of the sliding seat in the vertical direction, preventing the sliding seat from shaking or tilting during the movement.

[0014] A guide groove is provided at the bottom of the sliding seat, which opens downward and is buckled to the upper part of the first plug row and the second plug row and slides with them. The guide groove is buckled to the upper part of the first plug row and the second plug row and slides with them, providing additional support and guidance for the sliding seat. This design further enhances the stability and reliability of the busbar temperature compensator.

[0015] Bolts for connecting the guide rail are installed on the fixed seat and the sliding seat. By connecting the fixed seat and the sliding seat with the guide rail through bolts, the busbar temperature compensator can be easily installed at the required position and fit closely with the guide rail. This not only improves the installation efficiency of the busbar temperature compensator, but also increases its flexibility and convenience in use.

[0016] In summary, the beneficial effects of the utility model are: the cooperation of the guide rod and the guide hole ensures the stability and accuracy of the sliding seat during movement. The guide rod not only limits the movement trajectory of the sliding seat, but also increases the stability of the structure, preventing the sliding seat from offsetting or shaking during movement. The material of the pad is aluminum. Aluminum, as a good thermal conductive material, can quickly transfer temperature changes to the plug-in board, thereby achieving rapid temperature compensation. The busbar temperature compensator of the present invention fully considers the needs of temperature compensation in structural design, and realizes temperature compensation through a mechanical structure. It has the advantages of simple and compact structure, high stability and reliability, and can be widely used in various electronic equipment and precision mechanical systems, providing strong support for system performance improvement and stability assurance.
