Description

Technical Field

[0001] This utility model relates to the field of electrical transmission technology, and in particular to a power distributor. Background Technology

[0002] As the power demand of remote devices gradually increases, people are demanding fewer cables and more stable power supply.

[0003] In existing technologies, remote devices are typically powered through a single-wire connection. This requires each remote device to be equipped with a long cable and to be connected to a corresponding connector on the control system.

[0004] This wiring method results in a large number of cables required to power remote devices, leading to higher cable procurement costs and complex wiring procedures. Long cables require long distances, occupying significant installation space. The messy cable arrangement hinders subsequent inspections and increases maintenance costs. Furthermore, one end of the long cable needs to be connected to the control system's connector, and the limited number of connectors restricts the number of long cables that can be connected, thus limiting the number of remote devices that can be connected. This wiring method also makes it difficult for personnel to effectively assess the power supply status of long cables, making maintenance and repair challenging when power supply is abnormal. The single-circuit wiring lacks a backup power source, and an abnormality in the sole power source affects the normal power supply to remote devices, resulting in an unstable power supply.

[0030] With the increasing power supply demand of remote devices, people have put forward the demand for less cable and more stable power supply. In the prior art, the remote device is usually powered by a single line, which results in the need to configure a long cable for one remote device and to correspondingly connect a line plug on the control system. This wiring method results in a large number of cables required for remote device power supply, high cost of purchasing cables, complex wiring steps, long cable wiring, occupation of more installation space, cable clutter affecting the later inspection of workers, high cost of long cable maintenance; and the end of the long cable needs to be connected to the line plug of the control system, the number of line plugs of the control system is limited, the number of long cables is limited, and the number of remote devices that can be connected is limited; in addition, this wiring method makes it difficult for people to effectively judge the power supply state of the long cable, and it is difficult to maintain and repair when the power supply state is abnormal.

[0031] Reference Figs. 1-3 The power supply distributor 100 provided by the application has stable power supply and low wiring cost.

[0032] The power supply distributor 100 comprises a shell 1, a circuit board 2 arranged in the shell 1, at least two independent power supply circuits arranged on the circuit board 2, a power line 3 connected with a power supply device, the power line 3 comprising at least two branch power lines 3, each branch power line 3 being connected with one power supply circuit to independently supply power to each power supply circuit, and at least two power supply ports 4 for connecting remote devices, each power supply port 4 being connected with at least two power supply circuits to be supplied with power by two power supply circuits.

[0033] It should be noted that the power supply device is a control system or a power supply wiring device.

[0034] The power supply port 4 is connected with an electric wire, and the other end of the electric wire is a remote device. The power supply port 4 is electrically connected with the circuit board 2, and the current input by the input end of the power line 3 flows through the circuit board 2 to the power supply port 4, and then flows into the remote device through the electric wire connected with the power supply port 4.

[0035] The circuit board 2 is provided with at least two power supply circuits, one branch power line 3 is connected in one power supply circuit, and the two power supply circuits independently supply power.

[0036] When the two power supply circuits have current flowing therethrough, the current of the power supply port 4 is the superposition value of the currents of the two power supply circuits flowing through the power supply port 4. When only one of the two power supply circuits has current flowing therethrough, the current of the power supply port 4 is the current in the single power supply circuit.

[0037] Two independent power supply circuits are standby for each other, when one of the power supply circuits is abnormally damaged, the other power supply circuit can normally supply power, so that the remote device can be normally powered, so that the power supply of the remote device is more stable, compared with the prior art that the remote device can only correspond to one power supply circuit, the technical scheme of the application has obvious progress.

[0038] The power supply port 4 is at least two, that is, one power supply distributor 100 of the application can connect at least two remote devices, the power supply distributor 100 is arranged close to the remote device, the plurality of remote devices and the power supply distributor 100 are connected through a plurality of short cables, and the power supply distributor 100 and the power supply are connected through a long cable. Compared with the prior art scheme of connecting to the power supply through a plurality of long cables, the total length of the cable of the application is shorter, the cost of the cable is lower, the wiring mode is more explicit, the maintenance personnel can adjust the plug-in position of the short cable of the remote device, the occupied space is smaller, the volume is smaller, and the cable connection is more simple.

[0039] One power supply distributor 100 of the application can correspond to a plurality of remote device wiring, only one power supply line 3 needs to be connected to the plug at the power supply device, which expands the number of remote devices corresponding to the power supply of one power supply device, and further reduces the installation material cost of power supply.

[0040] In some embodiments of the application, the power supply distributor 100 further comprises a solid glue 5, which is pasted in the shell 1 and located on the side of the circuit board 2 away from the mounting port; the shell 1 comprises a mounting side 11 provided with a mounting port, and the projection of the solid glue 5 on the mounting side 11 can cover the projection of the circuit board 2 on the mounting side 11.

[0041] The adhesive can adopt a solid glue 5 which solidifies in air and is insoluble in water. After the power supply port 4 is welded, the fixing glue is poured into the space behind the circuit board 2 in the shell 1, and the fixing glue covers the entire circuit board 2. When the fixing glue solidifies, the solid glue 5 tightly adheres to the back side of the circuit board 2, which can greatly reduce the contact probability of water and the circuit board 2 and various powered circuit elements, and the waterproof level can reach IP67. Compared with the prior art digital module which can only reach IP20 waterproof level, the application has obvious progress.

[0042] In some embodiments of the application, the input end of the power supply line 3 of the power supply distributor 100 is connected to an extension line, the input end of the extension line is connected to the power supply device, the extension line selects a special power supply line 3 extension line in the industry, and the length of the extension line is selected according to the distance between the power supply distributor 100 and the power supply device to adapt to more different distance requirements.

[0043] In some embodiments of this application, there are two power supply circuits, namely a first power supply circuit and a second power supply circuit.

[0044] The housing 1 of the power distributor 100 is provided with a first power indicator light 61. The first power supply circuit includes the first power indicator light 61, which is used to provide feedback on the power supply status of the first power supply circuit.

[0045] Users can clearly determine the status of the first power supply circuit through the first power indicator light 61 without additional inspection, making it convenient for inspection and maintenance and easier to troubleshoot.

[0046] The housing 1 of the power distributor 100 is provided with a second power indicator light 62. The second power supply circuit includes the second power indicator light 62, which is used to provide feedback on the power supply status of the second power supply circuit.

[0047] Users can clearly determine the status of the second power supply circuit through the second power indicator light 62, eliminating the need for additional inspection and maintenance, thus facilitating troubleshooting. Users connect the power input using an industry-specific extension cable. When each power supply port 4 is powered, the corresponding indicator light will illuminate. Then, connect the short cable of the device being used to the power supply port 4, and the remote device will be powered on and operational.

[0048] In some embodiments of this application, when there are multiple power supply ports 4 arranged in two columns, the first power indicator light 61 and the second power indicator light 62 are positioned in the middle of the two columns of power supply ports 4, so that users can easily observe the power supply status of each power supply port 4.

[0049] In some embodiments of this application, the first power indicator light 61 is positioned close to the power line 3, and the second power indicator light 62 is positioned away from the power line 3. The first power indicator light 61 is positioned on the side of the second power indicator light 62 that is close to the power line 3, so that users can easily find the indicator lights of different power supply circuits corresponding to each power supply port 4, and easily judge the power supply status of different power supply circuits.

[0050] When the first power indicator light 61 displays the first color, the power supply status of the first power supply circuit is normal; any other color different from the first color indicates that the power supply is abnormal.

[0051] When the second power indicator light 62 displays the second color, the power supply status of the second power supply circuit is normal; any other color different from the second color indicates that the power supply is abnormal.

[0052] In some embodiments, the first color and the second color are the same color.

[0053] In some embodiments of this application, the housing 1 is a high-precision component manufactured as an integral part of a CNC machine tool. It is generally a long rectangular parallelepiped and includes a mounting side 11 with a mounting port, and four extended side 12 connected to the edge of the mounting side 11. The included angle between the extended side 12 and the mounting side 11 is 90 degrees, and the mounting side 11 is provided with multiple mounting ports.

[0054] The circuit board 2 and the mounting side 11 are fastened together with screws so that the circuit board 2 is secured inside the housing 11 and will not fall off as the power distributor 100 moves.

[0055] The mounting side 11 has a top opening for inserting screws, which can be driven into the top opening to securely connect the power distributor 100 and the mounting side 11.

[0056] The four extended sides 12 are provided with rounded corners at the joints to make the joints of the four extended sides 12 smooth and reduce the probability of scratches during maintenance and installation by installers and users, and also make the housing 1 more aesthetically pleasing.

[0057] In some embodiments of this application, the number of power supply ports 4 is 2n, where n is a positive integer.

[0058] In the embodiments shown in the accompanying drawings, the housing 1 is provided with eight power supply ports 4, arranged symmetrically in two rows, so that eight power supply ports can be installed on the mounting side 11 of the housing 1 and are elongated, so that the power distributor 100 is smaller in size.
