Description

Technical Field

[0001] The utility model relates to a telescopic device, and more specifically, to a connecting device for a sliding contact wire. Background Art

[0002] The traditional sliding contact wire is composed of an E-shaped frame made of angle steel and an insulator assembly fixed on the factory building frame, and generally can meet the speed regulation requirements in general application scenarios. However, in scenarios with a large temperature difference in the on-site environment, relying solely on the E-shaped frame device often fails to meet the requirements. For example, when the on-site environmental temperature is high, the sliding contact wire expands due to the high temperature. Since the sliding contact wires are connected end to end, the expansion cannot be released, resulting in the sliding contact wire being distorted and deformed. A large deformation amount is likely to cause the conductive slider to fall off and equipment accidents to occur. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a connecting device for a sliding contact wire to avoid the problem that the conductive slider is likely to fall off due to the distortion and deformation of the sliding contact wire caused by the influence of temperature change.

[0005] The connection unit includes a first conductor, a second conductor and a mounting pressing plate; the mounting pressing plate is arranged above the sliding contact wire, and a plurality of first conductors are provided between the mounting pressing plate and the sliding contact wire. A gap is provided between adjacent two of the first conductors, and a second conductor is provided in each gap. The mounting pressing plate is provided with a plurality of fasteners penetrating through the mounting pressing plate and all the conductors, and the fasteners are tightly connected with the sliding contact wire; the first conductor extends into the deformation distance, and the first conductors in the two connection units are inserted and contact-connected with each other.

[0006] As a further improvement, the thicknesses of the first conductor and the second conductor are the same.

[0007] As a further improvement, both the first conductor and the second conductor are copper plates.

[0008] As a further improvement, one end of the first conductor extending into the deformation distance is wedge-shaped.

[0010] As a further improvement, the mounting pressure plate is a pressure ceramic plate.

[0012] Beneficial Effects

[0013] The advantages of the utility model are that a first conductor and a second conductor are arranged between the mounting plate and the busbar, and the conductors of the two connecting units are plugged into each other to form a connecting device that can perform telescopic activities between the two busbars, thereby satisfying the deformation amount caused by temperature changes while ensuring the normal use of the busbar, effectively ensuring the stable production.

[0017] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0018] See also Figure 1 - Figure 2 The utility model provides a connecting device for a busbar, comprising two connecting units 2 with the same structure, and the two connecting units 2 are respectively installed at the head end of one busbar 1 and the tail end of the other busbar 1, and a deformation distance 3 is provided between the two busbars 1.

[0019] The connecting unit 2 includes a first conductor 22, a second conductor 23 and a mounting pressing plate 21. Among them, the thicknesses of the first conductor 22 and the second conductor 23 are the same to ensure that the gap formed after the conductors are stacked can accommodate the conductors of another connecting unit 2 and make the conductors of the two connecting units 2 contact each other. The mounting pressing plate 21 is arranged above the sliding contact wire 1. There are four first conductors 22 between the mounting pressing plate 21 and the sliding contact wire 1. There is a gap 24 between two adjacent first conductors 22. A second conductor 23 is arranged in each gap 24. The mounting pressing plate 21 is provided with a plurality of fasteners 25 penetrating through the mounting pressing plate 21 and all the conductors. The fasteners 25 are fixedly connected to the sliding contact wire 1, thereby realizing the installation and fixation of the mounting pressing plate 21 and the conductors. The first conductor 22 extends into the deformation spacing 3. The first conductors 22 in the two connecting units 2 are inserted into and contact each other, thereby realizing the electrical connection between the two sliding contact wires 1.

[0020] In this embodiment, copper plates with a thickness of 1 mm are used to make two different specifications of conductors. One is cut into a strip with a length of 400 mm * a width of 20 mm as the first conductor 22; the other is cut into a strip with a length of 100 mm * a width of 20 mm as the second conductor 23. After manufacturing, the two different specifications of copper sheets are stacked one by one in a long and short order and aligned, so that there is a certain gap between the first conductors 22 protruding from the mounting pressing plate 21, which is the thickness of one copper plate. Three holes of M8Ф8 are opened on both the first conductor 22 and the second conductor 23. These three holes correspond to the threaded holes on the sliding contact wire 1, and three corresponding holes are also opened on the mounting pressing plate 21. Then, the mounting pressing plate 21 and the conductors are fixed on the sliding contact wire 1 by using fasteners 25, that is, bolts, to form a connecting unit 2. A connecting unit 2 is installed at the end of the previous sliding contact wire 1 and the head of the next sliding contact wire 1. The first conductors 22 of the two connecting units 2 after installation are inserted into each other in the gap and form the function of contact conduction. When the ambient temperature is high and the two sliding contact wires 1 expand, the whole connecting device shows a shrinking scene, that is, the two connecting units 2 approach each other and the deformation spacing 3 becomes smaller. When the ambient temperature is low and the two sliding contact wires 1 contract, the connecting device extends, that is, the two connecting units 2 move away from each other. However, since there is an overlapping part between the first conductors 22 of the two connecting units 2, the extension amount cannot cause the electrical connection between the two sliding contact wires 1 to be disconnected, so as to ensure the normal use of the sliding contact wire 1 and meet the deformation amount caused by temperature change on the premise, effectively ensuring the stable progress of production.

[0021] Preferably, one end of the first conductor 22 extending into the deformation spacing 3 is wedge-shaped. Such a design is conducive to the insertion between the first conductors 22 of the two connecting units 2 and is convenient for operation.

[0022] Preferably, the mounting plate 21 is a pressure ceramic plate, which plays a role in insulating and protecting the upper part of the connection unit 2. The bottom of the pressure ceramic plate is provided with crisscross patterns, which is conducive to pressing the conductor.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
