Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

As shown in fig. 1 to 6, an embodiment of the present invention provides a multi-current power distribution apparatus, including:

a socket mounting plate 1: the socket mounting plate 1 is a mounting substrate of the whole device, and is a mounting substrate of the copper bar mounting plate 2 and a mounting substrate of the socket 6. As shown in fig. 3, the mounting distance between the sockets 6 is small, and the copper bar mounting plate 2 is mounted by utilizing the gap between the sockets, so that the space is very compact. The socket mounting plate 1 is a bearing part of the socket and is also butted with a device in front of the socket so as to ensure that the socket 6 is inserted in place. The socket mounting plate 1 may be made of aluminum.

A plurality of copper bar mounting panels 2: the copper bar mounting plate 2 is a mounting plate for a copper bar 3, a copper bar 4 and a copper bar 5, as shown in fig. 4. Because the copper bars need to be insulated, the copper bar mounting plate is made of an insulating material. In order to fix the copper bar on the mounting plate, a fixing hole is reserved at the corresponding position of the copper bar, and the copper bar is fixed by a screw made of an insulating material. Because the polytetrafluoroethylene has high and low temperature resistance, good dielectric property and good mechanical property, the polytetrafluoroethylene material can be selected to manufacture the copper bar mounting plate 2 and the like. The copper bar is in the form of the copper bars A3, B4 and C5, and current in three forms can be input, and the copper bars can be expanded if current in other forms is input.

One A copper bar 3: is arranged on the copper bar mounting plate 2 and is an input and output carrier of the current A. The sectional area of the copper bar meets the natural heat dissipation requirement, and the sectional area (mm2) is not less than 2.5 x current (A). In the present embodiment, the number of the a copper bars 3 is only 1, and actually, the number and the positions of the a copper bars 3 can be adjusted as needed. The current is shown in the trend of the A copper bar 3 and the structural shape of the A copper bar 3, as shown in figure 9.

One B copper bar 4: is arranged on the copper bar mounting plate 2 and is an input and output carrier of the current B. The sectional area of the copper bar meets the natural heat dissipation requirement, and the sectional area (mm2) is not less than 2.5 x current (A). Similarly, the number and the position of the B copper bars 4 can be adjusted according to the requirement. The current is shown in the trend of the B copper bar 4 and the structural shape of the B copper bar 4, as shown in figure 10.

A C copper bar 5: and the current C is installed on the copper bar installation plate 2 and is an input and output carrier of the current C. The sectional area of the copper bar meets the natural heat dissipation requirement, and the sectional area (mm2) is not less than 2.5 x current (A). Similarly, the number and the position of the C copper bars 5 can be adjusted according to the requirement. The current is shown in the trend of the C copper bar 5 and the structural shape of the C copper bar 5, as shown in FIG. 11.

Socket 6: the socket is arranged on the socket mounting plate 1 and is a carrier required to be powered. Each socket is provided with a bonding wire 8 for current input, and the bonding wires 8 are connected with 3 copper bars, so that each socket can input different currents. Therefore, 3 kinds of current are arranged on each socket and respectively correspond to the A copper bar 3, the B copper bar 4 and the C copper bar 5. The current is accessed from the input end of the copper bar and distributed to each socket on the socket board, and the sockets are butted with the front devices to realize the transmission of the current.

The input end and the output end are provided with threads (or welding columns 7), so that connection can be reliably realized, and disassembly is convenient, as shown in figures 1 and 2. The input of the small current can be connected by a cable welding mode and directly welded on the welding column 7. For the input of large current, such as the A copper bar 3 and the B copper bar 4, the direct connection can be realized through screws, and the welding column connection mode is replaced. Aiming at the input and output ports in the form of the welding column, the welding line can be directly welded on the welding column without welding the copper bar, and the problem that the welding cannot be carried out due to the overlarge area and the too fast heat dissipation of the copper bar is solved through the connection mode. In order to discharge the air and smoothly flow down the solder, a vent hole 11 may be formed in the lower middle portion of the solder column 7. In addition, the welding column 7 and the copper bar can be connected by screw threads. In the example of the present invention, the copper bar 3 a has 1 input terminal and 5 output terminals, the copper bar 4B has 1 input terminal and 6 output terminals, the copper bar 5C has 1 input terminal and 1 output terminal, and the positions are shown in fig. 6.

Because red copper has better electric conductive property, the material of the welding column 7, the A copper bar 3, the B copper bar 4 and the C copper bar 5 can be selected from the red copper. However, the strength of the red copper is not high, and in order to ensure reliable connection, a brass sleeve 9 can be added at the input end of the copper bar for inputting large current (such as an A copper bar 3 and a B copper bar 4), the brass sleeve 9 is embedded into the red copper in a threaded sleeve manner, and the input current is connected with the brass sleeve through a screw. Through adopting the harder brass bush of material to pass through, can effectively reduce wearing and tearing, increase of service life, the brass bush can be dismantled alone moreover, has reduced the cost and the degree of difficulty of maintenance change, has both guaranteed the connection reliability, has also avoided electric conductive property to descend. The input of small current can still adopt the mode of welding column and wire. For convenient installation, the inner side and the outer side of the brass sleeve can be processed into thread forms, and tool operation openings are reserved. After the copper bar is arranged, the pin 10 can be matched to prevent the copper bar from loosening.

For the present example, the trend of the three currents is:

the input of the first current, as shown in fig. 9, is connected to the input end 12 of the a copper bar 3 through a screw. The current passes through the A copper bar 3 and then passes through the A copper bar output end 13 (the welding columns distributed on the A copper bar), part of wires on the socket are welded on the A copper bar output end 13, and the current is distributed to each socket through the path.

The input of the second current, as shown in fig. 10, is connected to the B copper bar input terminal 14 through a screw. The current passes through the B copper bar 4 and then passes through the B copper bar output end 15 (the welding columns distributed on the B copper bar), part of wires on the socket are welded on the B copper bar output end 15, and the current is distributed to each socket through the path.

The third current input, as shown in fig. 11, is welded to the input terminal 16 of the C-bar by a bonding wire. The current passes through the C copper bar 5 and then passes through the C copper bar output end 17, part of wires on the socket are welded to the C copper bar output end 17, and the current is distributed to each socket through the path.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
