It will be appreciated that the orientation of the bus device 1 may also vary depending on the specific application.

Fig. 1 shows a perspective view of a bus device 1 according to the invention. The bus device 1 has a housing 10, with an input line 21 extending into the housing 10 from one side of the housing 10 and at least one output line 22, for example three output lines 22 as shown, extending from the other side of the housing 10. The housing 10 may be made of an insulating material such as plastic, resin, or the like.

As shown in fig. 1 and as can be seen in connection with fig. 2, the housing 10 comprises two parts, namely an upper housing half 11 and a lower housing half 12, which are more clearly identified in fig. 2, the upper housing half 11 and the lower housing half 12 preferably being connected together in a relatively movable manner, so that the housing 10 can be opened and closed. For example, as shown in fig. 1 and 2, an upper half case 11 and a lower half case 12 of a case 10 are connected to each other by a hinge 13 so that the upper half case 11 and the lower half case 12 can pivot relative to each other, thereby opening and closing the case 10.

A plurality of string holes 60 may be provided on the housing 10, and the string holes 60 are arranged along the circumference of the housing 10. For example, in the structure shown in the drawings, the hinge portion 13 is provided on one side of the housing 10, three line holes 60 are provided on each of two opposite sides adjacent to the side on which the hinge portion 13 is provided, and one line hole 60 is provided on the side opposite to the side on which the hinge portion 13 is provided. The arrangement of these wire holes 60 can be seen more clearly in the exploded perspective view shown in fig. 2.

These line holes 60 may include an input line hole 61 through which the input line 21 extends and an output line hole 62 through which the output line 22 extends. In the structure shown in the drawing, the input line hole 61 is a line hole 60 provided on the side opposite to the hinge portion 13, and the input line 21 extends through the input line hole 61 to the inside of the housing 10. The output line holes 62 are line holes 60 provided on two opposite sides adjacent to the side where the hinge portion 13 is provided, and the three output lines 22 extend from the housing 10 via three output line holes 62 on one side thereof.

As can be seen more clearly in fig. 2, the bus device 1 also comprises a copper bus bar 40, which copper bus bar 40 is accommodated in the housing 10. An input line connection terminal 23 is provided on one end of the input line 21 projecting into the housing 10, and an output line connection terminal 24 is provided on one end of the output line 22 projecting into the housing 10. The input line 21 and the output line 22 can be connected to the copper bus bar 40 accommodated inside the case 10 through the input line connection terminal 23 and the output line connection terminal 24. For example, in the preferred construction shown in the figures, the connection of the input and output lines 21 and 22 to the copper bus bar 40 is achieved by a combination of nuts 31 and bolts 32. Wherein a connection hole is formed on the input line connection terminal 23 of the input line 21, and the connection hole is engageable with one of the plurality of bolts 32 provided on the copper bus bar 40. Then, a nut 31 may be screwed onto the bolt 32 until the input line connection terminal 23 is fastened to the copper busbar 40. Similarly, a connection hole is formed in the output line connection terminal 24 of the output line 22, and the connection hole is engageable with the corresponding bolt 32 of the copper bus bar 40, and the output line connection terminal 24 is fastened to the copper bus bar 40 by engagement between the nut 31 and the bolt 32.

In order to improve the fastening effect, at least one spacer 33 may be further provided, for example, the spacer 33 may be provided between the nut 31 and the input line connection terminal 23 and the output line connection terminal 24, and the spacer 33 may be further provided between the copper bus bar 40 and the input line connection terminal 23 and the output line connection terminal 24.

Preferably, a locking structure 50 is provided on the housing 10 for preventing the upper and lower half- shells 11 and 12 of the housing 10 from being unintentionally separated after the housing 10 is closed.

As shown in fig. 2, in an exemplary configuration, the locking structure 50 includes a locking spring 51, the locking spring 51 being disposed on the upper housing half 11. At a corresponding position on the lower half-shell 12, a locking ring 52 is provided, in which locking spring 51 can snap-fit when the housing 10 is in the closed state, so as to lock the relatively closed position between the upper half-shell 11 and the lower half-shell 12. Preferably, as shown, one locking spring 51 is provided on each of the opposite sides of the upper half-shell 11, and correspondingly, one locking ring 52 is provided at each of the corresponding positions on the opposite sides of the lower half-shell 12.

The locking spring 51 is in the form of a cantilever arm extending from one side edge of the upper housing half 11, which can be slightly deformed. In the process of closing the housing 10, the locking elastic sheet 51 is inserted into the locking ring 52, and under the action of the force generated by the mutual contact between the locking elastic sheet 51 and the locking ring 52, the locking elastic sheet 51 is deformed, so that the locking elastic sheet 51 is allowed to be inserted into the locking ring 52, and after the locking elastic sheet 51 is inserted in place, the original shape is recovered, so that the locking elastic sheet 51 is clamped with the locking ring 52, and the locking elastic sheet 51 is prevented from being withdrawn from the locking ring 52. When the housing 10 is to be opened, the locking spring 51 may be pressed inwardly, deforming it, allowing the locking spring 51 to be withdrawn from the locking ring 52, thereby enabling the housing 10 to be opened.

In the process of installing the bus apparatus 1 of the present invention, the input line connecting terminal 23 of the output line 22 and the output line connecting terminal 24 of the input line 21 are firstly sleeved on the bolt 32 on the copper bus bar 40, and then the nut 31 is screwed on the bolt 32 and tightened to fasten the input line connecting terminal 23 and the input line connecting terminal 23 on the copper bus bar 40. Then, the upper half case 11 is closed onto the lower half case 12, so that the locking spring 51 of the upper half case 11 is snapped into the locking ring 52 of the lower half case 12, and the case 10 is locked in the closed state, i.e., the state shown in fig. 1. In this way, the case 10 made of an insulating material can achieve good insulation of the input line 21, the output line 22 and the copper bus bar 40 made of a conductive material, effectively avoiding the occurrence of a short circuit phenomenon.

Fig. 3 shows the installed bus device 1, the bus device 1 being in an open state. Three output wires 22 extend from three output wire holes 62 on the right side of the bus device 1. Of course, the output lines 22 may also be configured using one or more of the three output line holes 62 on the left side of the bus device 1 shown in fig. 3, depending on the actual application and requirements.

The preferred construction of the bus device 1 of the invention shown in the drawings has been described in detail above, and obvious modifications and variations can be made by a person skilled in the art on the basis of the disclosed construction, while remaining within the scope of the disclosure.

For example, in the structure shown in the drawings, a hinge 13 is provided between the upper and lower half shells 11 and 12 to connect the upper and lower half shells 11 and 12 together with relative movement. Other forms of attachment structures may be provided, as will be appreciated by those skilled in the art. Even, the connecting structure between the upper and lower half cases 11 and 12 may be omitted, that is, the upper and lower half cases 11 and 12 may be two parts separated from each other.

In the preferred construction shown in the drawings, three wire holes 60 are provided on each of two opposite sides adjacent to the side on which the hinge portion 13 is provided, and one wire hole 60 is provided on the side opposite to the hinge portion 13. While in other embodiments, other numbers of wire holes 60 may be provided as desired and are not necessarily limited to the configuration shown in the figures. For example, one wire hole 60 may be provided on each side; in the case where no connecting structure is provided between the upper half case 11 and the lower half case 12 as described above, the line holes 60 may be provided on all the sides of the bus device 1.

Further, any one of the line holes 60 on the bus device 1 may be used as the input line hole 61 of the input line 21, and the other line holes 60 may be used as the output line holes 62 of the output line 22.

It can be seen that the bus device 1 of the present invention can realize flexible configuration of the input line 21 and the output line 22.

The input line 21 and the output line 22 may be installed in other ways than the bolt-and-nut structure for connection between the copper bus bar 40 and the input line 21 and the output line 22 disclosed above with reference to the drawings. For example, a receptacle may be provided in one of the input line connection terminal 23 and the output line connection terminal 24 and the copper bus bar 40, and a plug may be provided in the other, so that the receptacle and the plug can be fitted to each other with interference. Alternatively, the connection between the input/ output lines 21 and 22 and the copper bus bar 40 may be achieved by soldering. In the case of using the soldering connection, the input line connection terminal 23 and the output line connection terminal 24 may be omitted.

In addition, although the copper bus bar 40 is used in the above disclosure of the present invention, other conductive materials may be used to manufacture the bus bar for the electrical connection between the input line 21 and the output line 22, which is also within the scope of the present invention.
