Description

Technical Field

[0001] The utility model relates to the technical field of power accessories, in particular to a terminal stopper for a busbar system. Background Art

[0002] At present, busbar systems are generally arranged horizontally in electrical cabinets. With the continuous development of emerging industries, the density of components in cabinets has increased significantly, and the application of busbar systems arranged vertically at 90 degrees is increasing. When the busbar system is arranged vertically at 90 degrees, it is easy to cause the circuit breaker to sag due to its own gravity and the influence of gravity acceleration during transportation.

[0003] In order to solve this problem in the prior art, the traditional approach is to install a support rail end stopper on the busbar adapter. However, this stopper is generally installed on the rail of the busbar adapter, so its external dimensions are limited, resulting in insufficient strength of the stopper. In this way, in the event of severe bumps during transportation, the stopper may break, causing the busbar system equipment to sag from time to time. However, if the circuit breaker sags during the operation of the busbar system, there is a serious safety hazard. Therefore, a terminal stopper for a busbar system is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the stopper is insufficient in strength, so that in the case of severe bumps during transportation, the stopper may break, causing the busbar system equipment to sag from time to time. However, if the circuit breaker sags during the operation of the busbar system, there is a serious safety hazard. The utility model provides a terminal stopper for the busbar system.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A terminal stopper for a busbar system comprises a connecting block, a connecting plate is arranged on the upper side of the connecting block, a contact surface is arranged on the lower side of the connecting block, and stepped surfaces are arranged on both sides of the connecting plate on the connecting block. The connecting block is symmetrically provided with fixing holes, and two fixing holes are respectively arranged on two stepped surfaces.

[0007] Preferably, the connection block and the connection plate are both made of POM polyoxymethylene resin, and the connection block and the connection plate are integrally formed.

[0008] Preferably, the widths of the connection block and the connection plate are set to be equal, and the width of the connection block and the connection plate is 19 millimeters, and the connection block, the connection plate and the busbar support are set to be equal in width.

[0009] Preferably, the spacing between the two fixing holes is set to thirty millimeters, and the width between the fixing holes and the width of the matching aperture on the busbar support are set to be equal spacing.

[0010] Preferably, a truncation surface is provided on the upper side of the connecting plate, and the distance between the truncation surface and the step surface is set to thirty-five millimeters. The truncation surface on the connecting plate is located in the middle of the circuit breaker, and the height of the step surface on the connecting block is set to thirteen millimeters. The combination of the connecting plate and the connecting block is in a step shape.

[0011] Preferably, the shape of the fixing hole is set to be a sinking hole, and the hole diameter sinking depth of the fixing hole is six millimeters. A fixing screw is matched in the fixing hole, and the overall length of the fixing screw is seven millimeters.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. In the utility model, the traditional busbar support can have the function of supporting the entire busbar system, and its structural strength is relatively good, so installing the stopper on the busbar support can obtain a better supporting effect. The set stopper can effectively prevent the circuit breaker from sagging when the busbar system is arranged vertically, thereby avoiding the occurrence of safety hazards and improving the safety of the entire busbar system.
