Description

Technical Field

[0001] This utility model relates to the field of capacitor insulating terminal technology, and in particular to an insulating terminal for capacitor cover plates. Background Technology

[0002] Insulating terminals for capacitor covers are components installed on capacitor covers. They consist of a cover, connecting base, insulating body, locking ring, etc., and are fixed by threads and mechanical engagement. Their functions are: electrical insulation, using insulating material to isolate the internal electrodes from external metal parts to prevent leakage; fixed connection, connecting internal and external circuits to prevent vibration and loosening; protective adaptation, reducing dust and moisture intrusion and adapting to different capacitors; and performance assurance, avoiding charge leakage and poor contact, ensuring stable operation of the capacitor. It is the capacitor's "safety interface," ensuring its normal operation and safe use.

[0003] However, when using existing capacitor cover plates, the insulating terminals are connected to the cover plate by screwing. However, the screw connection can loosen due to vibration, which can cause a series of problems, such as decreased electrical connection stability, poor contact, increased contact resistance, local heating during operation, and even electric arcing. This can damage the insulation performance of the insulating body and increase the risk of leakage. Therefore, there is a need for an insulating terminal for capacitor cover plates. Utility Model Content

[0004] The purpose of this invention is to provide an insulating terminal for capacitor cover plates, which solves the problem of loosening of spiral connections due to vibration in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating terminal for a capacitor cover plate, comprising a cover plate, a connecting base with its axis protruding upward perpendicularly to its diameter and having threads on its outer wall on the upper surface of the cover plate, an insulating body spirally connected to the connecting base above the cover plate, a locking ring on the bottom periphery of the insulating body, and a triangular engaging groove on the upper surface of the cover plate that cooperates with the locking ring to lock the insulating body in rotation.

[0006] Preferably, the insulating body includes an insulating cylinder and an insulating partition, and the inner wall of the insulating cylinder is provided with an insulating partition that provides insulation protection.

[0007] Preferably, a groove is provided between the insulating cylinder and the insulating partition for the connecting base to be spirally connected.

[0008] Preferably, the locking ring includes a locking ring and a triangular locking block, the triangular locking block being connected to the bottom of the locking ring by an elastic element.

[0009] Preferably, the cross-section of the triangular card block is triangular.

[0010] Preferably, the elastic element is elastic rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By fitting the insulating body onto the outer wall of the connecting base and turning it clockwise, the insulating body can be aligned with the cover plate. At this time, the connecting base passes through the gap between the insulating cylinder and the insulating partition. The insulating cylinder strengthens the insulation to protect the lead terminal. At the same time, the locking ring abuts against the triangular locking groove. When the triangular inclined surface of the triangular locking block rotates, it will rely on the elastic rubber to contract. When it is rotated to the bottom, the triangular locking block uses the elastic rubber to make the vertical surface of the triangular locking groove to complete the counterclockwise locking and prevent the workpiece from vibrating and loosening.

[0020] 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.

[0021] This utility model relates to an insulating terminal for a capacitor cover plate, such as... Figure 1-6As shown, it includes a cover plate 1, an insulating body 2 is spirally connected to the top of the cover plate 1, a connecting sleeve 3 opposite to the insulating body 2 is provided at the bottom of the cover plate 1, a threaded groove is provided on the inner wall of the insulating body 2, and a connecting base 4 spirally connected to the insulating body 2 is fixed at the top of the cover plate 1. The outer wall of the connecting base 4 is provided with threaded ribs, and the insulating body 2 can be screwed onto the outer wall of the connecting base 4.

[0022] Among them, such as Figure 5 As shown, the insulating body 2 includes an insulating cylinder 21 and an insulating partition 22. The insulating cylinder 21 is funnel-shaped, and the insulating partition 22 is provided on the inner wall of the bottom of the insulating cylinder 21. The insulating partition 22 serves to protect the lead terminal and strengthen the insulation. There is a space between the insulating cylinder 21 and the insulating partition 22 for the connecting base 4 to be spirally connected, so that the connecting base 4 passes through the space to complete the spiral connection.

[0023] Furthermore, a locking ring 5 is connected to the bottom outer wall of the insulating body 2. The insulating body 2 can be locked onto the cover plate 1 by the locking ring 5 to prevent the spiral from loosening due to vibration. The top surface of the cover plate 1 is provided with triangular engaging grooves 6 arranged in a ring and adapted to the locking ring 5.

[0024] Among them, such as Figure 6 As shown, the locking ring 5 includes a locking ring 51 and a triangular locking block 52. The bottom of the locking ring 51 is connected to the triangular locking block 52 by an elastic element, preferably elastic rubber. The cross-section of the triangular locking block 52 is triangular, which engages with the triangular engaging groove 6. The inclined surface of the triangle contracts, while the vertical surface serves to abut and lock. When the screw connection is made, the triangular locking block 52 contracts into the locking ring 51, and the elastic rubber abuts the triangular locking block 52 into the triangular engaging groove 6, so that the vertical surface is engaged into the triangular engaging groove 6 to complete the locking.

[0025] Furthermore, through holes are provided inside the cover plate 1, the insulating body 2, the connecting sleeve 3, and the connecting base 4 for the lead terminals to pass through.

[0026] In practical use: By fitting the insulating body 2 onto the outer wall of the connecting base 4 and turning it clockwise, the insulating body 2 can be connected to the cover plate 1. At this time, the connecting base 4 passes through the gap between the insulating cylinder 21 and the insulating partition 22. The insulating cylinder 21 strengthens the insulation to protect the lead terminal. At the same time, the locking ring 5 will abut against the triangular engagement groove 6. When the triangular inclined surface of the triangular block 52 rotates, it will rely on the elastic rubber to contract. When it rotates to the bottom, the triangular block 52 uses the elastic rubber to make the vertical surface of the triangular block 52 engage in the triangular engagement groove 6, completing the counterclockwise locking and preventing the workpiece from vibrating and loosening.
