Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a housing for a dual power transfer switch that facilitates wiring. Background Technology

[0002] The dual power transfer switch mainly consists of a main / standby power transfer switch, a transfer actuator, and a controller. The controller monitors and collects the switch status in real time through a sampling line, and drives the actuator based on the monitored status information to realize the switching of power supply, thereby switching from a faulty power supply to a normal power supply. This ensures the stability of the power supply to the load end and the smooth and reliable operation of the load equipment.

[0003] Existing dual-power transfer switches contain both high-voltage and low-voltage conductors, but these are not separated. The low-voltage conductors are primarily used for signal or data transmission, while the high-voltage conductors, due to their significant electromagnetic interference, radiation, noise, and stray signals, negatively impact the low-voltage conductors, leading to signal quality degradation or data transmission errors. This can prevent the circuit board from accurately identifying and automatically switching the load from the main power supply to the backup power supply when the main power supply fails or experiences voltage anomalies, thus affecting the continuity and stability of the power supply.

[0004] In addition, when fixing strong and weak current wires, tools such as cable ties or fixing clamps are required, which not only affects wiring efficiency but also increases manufacturing costs. Therefore, optimizing the wiring layout and fixing method is of great significance for improving the performance of dual power transfer switches and reducing costs. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the traditional dual-power transfer switch design and provide a product that ensures the security and integrity of data transmission, improves wiring efficiency, and reduces manufacturing costs.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A housing for a dual-power transfer switch that facilitates wiring includes a housing and a cover fixed to the housing. One side of the housing has a low-voltage channel and the other side of the housing has a high-voltage channel. The cover has a rotatable turntable, and a micro switch is provided on one side of the turntable. The low-voltage channel has a wire hole and is close to the terminal of the micro switch.

[0008] Preferably, the turntable is provided with a triggering part.

[0009] Preferably, the transmission plate of the micro switch is located on the moving trajectory of the trigger part.

[0010] Preferably, the housing contains a first circuit board, and the housing has a cavity for accommodating the first circuit board, the cavity being connected to a low-voltage channel and a high-voltage channel.

[0011] Preferably, the cover is provided with a second circuit board and is located above the first circuit board.

[0012] Preferably, the entrances to the low-voltage and high-voltage channels are spaced apart from the bottom of the housing to allow wires to bend and enter.

[0013] Preferably, the threading hole has a notch.

[0014] Beneficial effects:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes separate low-voltage and high-voltage channels for distributing low-voltage and high-voltage wires, effectively preventing interference from high-voltage wires to low-voltage wires. This significantly improves the signal transmission quality and data transmission accuracy of low-voltage wires, enhancing the accuracy of the circuit board in determining power status and effectively overcoming problems in existing technologies. Furthermore, the low-voltage and high-voltage channel design effectively constrains multiple low-voltage and high-voltage wires, eliminating the need for cable ties or clamps, thus improving wiring efficiency and reducing constraining costs.

[0026] Reference example Figures 1 to 4 A housing for a dual-power transfer switch with easy wiring is disclosed, comprising a housing 1 and a cover 2 fixed to the housing 1. A low-voltage channel 11 is provided on one side of the housing 1, and a high-voltage channel 12 is provided on the other side. The cover 2 has a rotatable turntable 3, and a micro switch 4 is provided on one side of the turntable 3. The low-voltage channel 11 has a wire-passing hole 111 located near the terminal of the micro switch 4. The low-voltage channel 11 and the high-voltage channel 12 are used for the distribution and arrangement of low-voltage and high-voltage wires, respectively, effectively preventing interference between high-voltage and low-voltage wires. This significantly improves the signal transmission quality and data transmission accuracy of the low-voltage wires, not only enhancing the accuracy of the circuit board in determining the power status but also effectively overcoming problems existing in the prior art. Simultaneously, the low-voltage and high-voltage channel 12 design can effectively constrain multiple low-voltage and high-voltage wires, eliminating the need for cable ties or clamps for constraint and fixation, thereby improving wiring efficiency and reducing constraint and fixation costs.

[0027] It is worth mentioning that the turntable 3 is provided with a trigger part 31, which is used to trigger the closing of the micro switch 4;

[0028] It is worth mentioning that the transmission plate of the micro switch 4 is located on the movement trajectory of the trigger part 31. The micro switch 4 is electrically connected to the first circuit board 5. Once the micro switch 4 is closed and conducting, it immediately triggers the first circuit board 5 to switch to the automatic operation mode, ensuring that the system responds quickly and enters the preset automatic control state.

[0029] It is worth mentioning that the housing 1 contains a first circuit board 5, and the housing 1 has a cavity 13 to accommodate the first circuit board 5. The cavity 13 is connected to the weak current channel 11 and the strong current channel 12. In the automatic operation mode, the first circuit board 5 uses built-in relays and contactors to automatically switch the load to the backup power supply when the main power supply fails or the voltage is abnormal, so as to ensure continuous and stable power supply. This design is known to those skilled in the art and will not be described in detail here. The cavity 13 is connected to the weak current and strong current channels 12, which makes it easy for the weak current wires to be directly connected to the connection ports of the first and second circuit boards 6. This optimizes the circuit layout, improves the connection efficiency, and also makes it easy for maintenance personnel to check the corresponding position of the wires after opening the cover 2, thus reducing the difficulty of maintenance.

[0030] It is worth mentioning that the cover 2 is equipped with a second circuit board 6, located above the first circuit board 5. The second circuit board 6 is equipped with multiple control buttons for adjusting and setting key parameters. Through these control buttons, users can flexibly configure the switching conditions and delay time of the dual power transfer switch, ensuring that the dual power transfer switch can achieve accurate and reliable operation in different application scenarios. This design is prior art known to those skilled in the art and will not be described in detail here.

[0031] It is worth mentioning that the entrances of the low-voltage channel 11 and the high-voltage channel 12 are spaced from the bottom of the housing 1 to allow wires to bend and enter.

[0032] It is worth mentioning that the wire hole 111 is provided with a notch 112. The notch 112 and the wire hole 111 form an L-shape, which facilitates the low-voltage wire to enter its L-shaped depth and be pre-fixed. When the cover 2 is fixed on the top of the housing 1, the notch 112 is completely blocked, effectively preventing the low-voltage wire from being exposed.

[0033] The above design scheme enables the product to achieve the advantages of ensuring the security and integrity of data transmission, improving wiring efficiency, and reducing manufacturing costs.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
