Technical Field

[0001] The utility model relates to the technical field of busbar contacts, in particular to a bridge-type plug-in busbar contact. Background Technique

[0002] At present, double power source automatic transfer switch electrical appliances and circuit breakers are widely used in the power system. In a drawer-type functional device, a tension spring is usually used to connect a conductive sheet to keep it connected to the busbar.

[0003] In the prior art, as disclosed in the application number: CN202120626479.5 with the name: Circuit Breaker, a plug-in groove for plugging into the busbar is provided in the connection component. The connection component includes a first connection contact unit and a second connection contact unit. The first connection contact unit and the second connection contact unit are arranged relatively at intervals so as to form a plug-in groove between the first connection contact unit and the second connection contact unit.

[0004] However, the connection component mentioned in the prior art is not easy to be stably connected to the busbar when connected to the busbar, and the conductive sheet is prone to looseness, resulting in the disconnection of the connection with the busbar, thereby affecting the conductive stability. Therefore, a bridge-type plug-in busbar contact needs to be designed. Content of the Utility Model

[0013] Further, the spring rod is located between two spacers, and the spacers are used to limit the horizontal movement of the spring rod.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0025] A bridge-type plug-in busbar contact, comprising a busbar 1. Mounting plates 7 are fixedly provided on both sides of the busbar 1. Symmetrically distributed clamping plates 5 are fixedly provided at one end of the busbar 1. A plurality of mounting holes are formed in the clamping plates 5, and round shafts 6 are fixedly connected in the mounting holes. The plurality of round shafts 6 are located between the two clamping plates 5.

[0026] A support plate 8 is fixedly installed at one end of the busbar 1 and between the two clamping plates 5. The support plate 8 is fixedly installed on three round shafts 6, so that the three round shafts 6 form a triangular structure. The support plate 8 is located at the center of the round shafts 6 to ensure the supporting force of the round shafts 6 and prevent the round shafts 6 from deforming.

[0027] Array-distributed spacers 3 are fixedly provided on the side surface of the support plate 8. The spacers 3 are horizontally arranged and fixedly installed on two horizontally arranged round shafts 6.

[0028] A conductive sheet 2 is fixedly installed between two adjacent spacers 3. The conductive sheet 2 is in a bridge-type structure, and inclined surfaces are formed at both ends of the conductive sheet 2 for the busbar 1 to be inserted between the two conductive sheets 2. Symmetrically distributed waist-shaped holes are formed in the conductive sheet 2. The waist-shaped holes are slidably connected with the round shafts 6, and arc-shaped grooves are formed in the conductive sheet 2.

[0029] A horizontally placed spring rod 4 is installed in the arc-shaped groove. The spring rod 4 is located between the two spacers 3. The spring rod 4 is limited by the spacers 3. The spring rod 4 is arranged between the three round shafts 6 in a triangular structure, and the spring rod 4 is located below one round shaft 6 and above the two horizontally arranged round shafts 6 at the same time.

[0030] In the state where the busbar 1 is not inserted, the spring rod 4 abuts against the round shaft 6 above it, and the other two round shafts 6 are located at the top of the waist-shaped holes. When the busbar 1 is inserted, the conductive sheet 2 moves vertically along the direction of the waist-shaped holes. Under the pressure of the round shaft 6 above it, the spring rod 4 is squeezed and deformed, exerting force to keep the two ends of the conductive sheet 2 stably connected to the busbar. At this time, the two horizontally arranged round shafts 6 are located at the bottom of the waist-shaped holes.

[0031] The working principle is as follows:

[0032] A plurality of conductive sheets 2 are strung together through three round shafts 6, and spacers 3 are installed between adjacent conductive sheets 2. A spring rod 4 is installed in the arc-shaped groove of the conductive sheet 2. The spring rod 4 is located between the two spacers 3 and below the round shafts 6 to limit the spring rod 4 and ensure that the spring rod 4 exerts a stable pressure on both ends of the conductive sheet 2.

[0033] In the state where the busbar 1 is not inserted, the spring rod 4 abuts against the circular shaft 6 above it, and the other two circular shafts 6 are located at the top of the waist-shaped hole. When the busbar 1 is inserted, the conductive sheet 2 moves vertically along the direction of the waist-shaped hole. Under the pressure of the circular shaft 6 above it, the spring rod 4 is squeezed and deformed, applying force to keep the two ends of the conductive sheet 2 stably connected to the busbar. At this time, the two horizontally arranged circular shafts 6 are located at the bottom of the waist-shaped hole.

[0034] The waist-shaped hole is used to slidably connect with the circular shaft 6 to guide the movement of the conductive sheet 2, ensuring that the movement of the conductive sheet 2 is more stable. Moreover, the setting of the spring rod 4 is more stable than the spring structure, and the installation is simple and convenient. At the same time, the spring rod 4 applies a constant pressure to the conductive sheet 2.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
