Description

Technical Field

[0001] The utility model belongs to the technical field of rigid contact network, and in particular relates to a novel busbar electrical connection wire clamp. Background Art

[0002] The busbar electrical connection clamp is an important component of the rigid contact network power supply system, which is used to ensure the conductive connection between the cable and the busbar or between the busbars. In the long-term operation process, the existing busbar electrical connection clamp (CN204020606U) has poor contact with the busbar due to busbar vibration and loose fasteners, resulting in ablation, damaging the electrical connection clamp, and in severe cases, damaging the busbar. Not only does it need to replace the electrical connection clamp, but it also needs to replace the entire busbar, resulting in great economic losses and high operating and maintenance costs. Utility Model Content

[0003] The utility model provides a novel busbar electrical connection clamp to overcome the deficiencies of the prior art.

[0004] The technical solution adopted by the utility model is: a new type of busbar electrical connection wire clamp, including two clamping blocks symmetrically clamped on both sides of the top of the busbar, the contact surface between the clamping blocks and the top of the busbar is formed with grooves along the line direction, an elastic contact piece is fixed in the groove, and the contact surface between the elastic contact piece and the busbar protrudes from the groove.

[0005] The elastic contact piece is a strip-shaped structure, and two sides thereof are riveted to the groove.

[0006] The grooves are symmetrically arranged along the axial direction of the busbar.

[0007] The elastic contact piece is a spring sheet or a watch strap contact finger.

[0008] The surfaces of the spring sheet and the strap contact finger are both silver-plated.

[0009] The clamping block is vertically provided with a connecting hole.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The utility model provides an elastic contact piece between the clamping block and the contact surface on the top of the busbar to ensure that the busbar and the electrical connection wire clamp can still be in reliable contact under long-term fatigue vibration, avoid arc burning, extend the service life of the busbar and the electrical connection wire clamp, and reduce operation and maintenance costs.

[0012] 2. The elastic contact member in the utility model is preferably a spring sheet or a watch strap contact finger, which provides a certain contact force through its own elasticity, avoids virtual contact on the contact surface, realizes effective electrical transition, and improves the current carrying capacity.
