Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment technology, and specifically to a novel plug structure for plugging into busbars. Background Technology

[0002] Busbar trunking features large current capacity and better electrical and mechanical performance. In power supply systems, it uses a plug-in method to connect the power supply of the main line to the plugs of the plug box through the busbar trunking, and then to the branch lines to form a power distribution system. Therefore, the contact performance between the plugs and the busbar trunking directly affects the safety and stability of the system.

[0003] In existing technologies, after the pins are connected to the conductor, the pins and conductors make line contact. The line contact resistance is relatively large, and the temperature rise at the connection point is relatively high. During the operation of the connection box, the pins are easily burned out, causing power failures such as phase loss. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a new type of plug structure for plugging into busbars. This solves the problem that in the existing technology, after the plug is connected to the conductor, the plug and the conductor are in line contact, resulting in high line contact resistance and high temperature rise at the plug connection point. This can easily burn out the plug during the operation of the plug box, causing power failures such as phase loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel plug structure for connecting busbars includes a plug body, the plug body including a connecting piece, and copper plug vertical sections symmetrically arranged on both sides of the connecting piece. The bottom of the copper plug vertical section is provided with an inwardly bent electrical contact bevel section. One end of the two electrical contact bevel sections contacts each other to form an access angle groove for conductor insertion. Spring plate connecting sections are symmetrically arranged on both sides of the bottom end face of the connecting piece. The bottom of the spring plate connecting section is provided with a transition bevel section. The bottom of the transition bevel section is provided with a clamping and fixing section extending between the copper plug vertical section and the electrical contact bevel section. The clamping and fixing section abuts against the electrical contact bevel section.

[0007] Preferably, the two spring sheet connecting sections are connected by rivets.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] After the insert body of this invention is connected to the conductor, the insert body and the conductor are in surface contact, which increases the contact area, reduces the contact resistance, and increases the current carrying capacity, thereby achieving the purpose of improving contact performance.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Example

[0017] This utility model provides a novel pin structure for plugging into busbars, see reference. Figure 1-3 As shown, the device includes an insert body, which includes a connecting piece 1. The connecting piece 1 has symmetrically arranged vertical copper insert sections 2 on both sides. The bottom of each vertical copper insert section 2 has an inwardly bent electrical contact slope section 3. The two electrical contact slope sections 3 are in contact at one end to form an access angle groove 7 for conductor insertion. The bottom end face of the connecting piece 1 has symmetrically arranged spring sheet connecting sections 4 on both sides. The bottom of each spring sheet connecting section 4 has an outwardly inclined transition slope section 5. The bottom of the transition slope section 5 has a pressing and fixing section 6 extending between the vertical copper insert section 2 and the electrical contact slope section 3. One end of the pressing and fixing section 6 abuts against the inner wall of the electrical contact slope section 3, so that the pressing and fixing section 6 deforms with the deformation of the electrical contact slope section 3.

[0018] The two spring sheet connecting sections 4 are connected by rivets 8, and the rivets 8 are made of copper, which increases the conductivity of the insert body.

[0019] The vertical section 2 and the inclined section 3 of the copper insert are made of copper or copper-zinc alloy according to the usage requirements, and the surface is tin-plated or silver-plated, which has good conductivity.

[0020] The spring plate connecting section 4, the transition inclined section 5, and the clamping and fixing section 6 all have good elasticity.

[0021] refer to Figure 3 As shown, after the conductor is inserted into the angled groove 7, the two electrical contact inclined sections 3 will deform, causing the electrical contact inclined sections 3 to adhere to the outer wall of the conductor. At the same time, the pressing and fixing section 6 will deform accordingly, and the conductor will be clamped and fixed by the elastic force of the pressing and fixing section 6 itself.

[0022] After the insert body of this invention is connected to the conductor, the insert body and the conductor are in surface contact, which increases the contact area, reduces the contact resistance, and increases the current carrying capacity, thereby achieving the purpose of improving contact performance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
