Detailed Description

It is specifically noted that the terms "first", "second" and "third" in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described by the following examples:

the utility model provides a power bus duct convenient to install, as shown in figure 1, the power bus duct comprises: the cable core 1 formed by a conductive material and the shell 2 formed by an insulating material, wherein the cable core 1 penetrates through the shell 2, the shell 2 is in a cylindrical shape, the cable core 1 is provided with a connecting plate 11 and two supports 12, the connecting plate 11 is fixed between the two supports 12, the outer side surface of each support 12 is an arc surface, the outer side surface of each support 12 is attached to the inner surface of the shell 2 (namely, the radian of the outer side surface is the same), and the length of the cable core 1 is greater than that of the shell 2.

In the power bus duct installation process, shell 2 is fixed on the bearing, and the outside of shell 2 is exposed at the both ends of sinle silk 1, and power supply system's brush is installed on sinle silk 1 to the brush can move on sinle silk 1. The two cores 1 can be connected by a connection box to increase the supply range or to form corners. The end of the core 1 may be connected to a terminal of a power supply line through a lug to obtain power.

Different from the traditional bus duct, in the utility model, because the outer shell 2 of the power bus duct is in a cylindrical shape, correspondingly, the supporting seat of the power supply system can also be in a cylindrical shape, when the power bus duct is installed, the angle can be adjusted at will, even in some inclined positions in a place, the power bus duct can also be stably installed, and the power bus duct is very convenient.

Secondly, since the housing 2 has a cylindrical shape, it is relatively uniformly applied with force, and the possibility of deformation is reduced even if it is collided or pressed by a foreign object.

Thirdly, because the outer side surface of the bracket 12 is an arc surface (namely a smooth curved surface) and does not contain an opening channel, the wire core 1 and the shell 2 can be extruded and molded together, the manufacturing process is simple, and the filling material is saved.

Specifically, the connection plate 11 has a screw hole 10, and the screw hole 10 is located outside the housing 2. The connection of the wire core 1 and the connection box or the adapter can be realized in a screw locking mode.

Specifically, as shown in fig. 2, the holder 12 includes: the supporting plate comprises two inner supporting plates 121 and an outer supporting plate 122, wherein the outer supporting plate 122 is arc-shaped, the two inner supporting plates 121 are separated from each other in the vertical direction, one end of each inner supporting plate 121 is fixed to the connecting plate 11, and the other end of each inner supporting plate 121 is fixed to the outer supporting plate 122.

More specifically, the angle between the two inner support plates 121 is less than 180 ° (i.e., the cross-section of the bracket 12 is fan-shaped). Through the angle setting, the cross section of the groove on the upper side and the lower side of the connecting plate 11 can be in a trapezoidal shape, and the installation of the electric brush can be guided.

Specifically, as shown in fig. 3, the inner surface of the housing 2 has four positioning ribs 21, two positioning ribs 21 are in contact with one bracket 12, and the other two positioning ribs 21 are in contact with the other bracket 12. Through the cooperation of location muscle 21 and support 12 can make sinle silk 1 fix inside shell 2, avoid sinle silk 1 to take place the rotation.

More specifically, the inner surface of the housing 2 also has two reinforcing ribs 22, and both reinforcing ribs 22 are located between the two brackets 12. Because the upper end and the lower end of the shell 2 are not in contact with the wire core 1 (or the bracket 12), the compressive strength is lower, the compressive strength can be improved by arranging the reinforcing ribs 22, and the service life is prolonged.

The above-described embodiments are merely preferred examples of the present invention, and not intended to limit the scope of the utility model, so that equivalent changes or modifications in the structure, features and principles of the utility model described in the claims should be included in the claims.
