Description

Technical Field

[0001] The utility model relates to the technical field of dual power supplies, in particular to an isolated dual power supply with stable connection. Background Art

[0002] Dual power refers to a device that can switch and is controlled by a microprocessor. The dual power automatic switch is a device controlled by a microprocessor and used to start switching between grid power and grid power or grid power and generator power in the power grid system, which can provide continuous power supply. In the case of a series of dual power supplies, when the common power suddenly fails or the power is cut off, the dual power switch will automatically switch to the backup power supply so that the equipment can still operate normally. The most common ones are elevators, fire protection, monitoring, lighting, etc., and the isolated dual power supply can avoid mutual influence between the two power supplies. When using the isolated dual power supply, it is necessary to ensure the stability of the line connection and avoid disconnection of the wiring.

[0003] The patent with application number CN202123395855.3 relates to the technical field of transfer switches, and discloses a highly safe isolated dual-power automatic transfer switch, including a switch body and a mounting plate, with two mounting plates, one side of the switch body is fixedly connected with a mounting cover, and the bottom of the switch body is fixedly connected with a heat dissipation shell, one side of the mounting plate is integrally formed with a plurality of mounting seats, one side of the mounting seat is integrally formed with a buckle, and the bottom and top of the inner wall of the switch body are integrally formed with a plurality of connecting buckles, and the connecting buckles are snapped with the buckles. The utility model can prevent arcing inside the switch body after the copper plate is separated from the contact, and avoid short circuit of the switch. The water inside the switch body will be concentrated downward through the gap of the drainage arc extinguishing grid and discharged from the through hole, avoiding short circuit caused by water conduction of the switch, and part of the heat generated during the operation of the switch will pass through the drainage arc extinguishing grid and be discharged by the heat dissipation shell to ensure the long-term safe operation of the switch.

[0004] However, this patent avoids short circuits when the switch is in use by draining arc extinguishing grids, thereby ensuring the safety of the isolated dual power supply when in use. However, when the connection between the isolated dual power supply and the cable becomes loose, it leads to unstable power supply or other problems, resulting in reduced safety of the isolated dual power supply.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 5 As shown, the utility model provides a stable connected isolated dual power supply including: an isolated dual power supply 1, a wiring board 2 fixedly connected to the isolated dual power supply 1, a one-way threaded rod 3 fixedly connected to the wiring board 2, a nut 4 threadedly connected to the one-way threaded rod 3, a cable 5 sleeved on the one-way threaded rod 3, the cable 5 sleeved on one end of the one-way threaded rod 3, and then the nut 4 is rotated to move downward through the one-way threaded rod 3 to squeeze and fix one end of the cable 5, completing the installation of the cable 5, and a support plate 6 fixedly connected to the isolated dual power supply 1, and the surface of the support plate 6 A reinforcing plate 7 is fixedly connected and fixedly connected to the surface of the isolated dual power supply 1. The supporting plate 6 supports the fixing component 8. The reinforcing plate 7 can increase the supporting force of the supporting plate 6. The fixing component 8 is fixedly installed on the supporting plate 6 to fix the cable 5. The protective component 9 protects the connection between the cable 5 and the isolated dual power supply 1. One end of the cable 5 passes through the fixing component 8 and the protective component 9, and then is connected to the isolated dual power supply 1, and then is fixed by the fixing component 8, and the connection between the cable 5 and the isolated dual power supply 1 is protected by the protective component 9.

[0023] The fixing assembly 8 includes a fixing frame 81 fixedly connected to the support plate 6, a slide groove 82 opened on the fixing frame 81, a slider 83 slidably connected to the slide groove 82, a pressure plate 84 fixedly connected to the slider 83, a bidirectional threaded rod 85 threadedly connected to the slider 83, and a rotating block 86 fixedly connected to one end of the bidirectional threaded rod 85. The bidirectional threaded rod 85 is rotatably connected to the fixing frame 81. Two sets of threads with opposite rotation directions are opened at both ends of the bidirectional threaded rod 85, and the threaded rod is driven to rotate by the rotating block 86.

[0024] Rotating the rotating block 86 drives the bidirectional threaded rod 85 to rotate. At this time, the slider 83 threadedly connected to the bidirectional threaded rod 85 will slide up and down inside the slide groove 82 and drive the pressure plate 84 to squeeze and fix the cable 5, ensuring that the shaking of the cable 5 caused by the maintenance of the isolated dual power supply 1 or other external forces will not be transmitted to the connection between the cable 5 and the isolated dual power supply 1, thereby ensuring that the connection between the cable 5 and the isolated dual power supply 1 is relatively stable and will not shake, thereby improving the stability of the connection between the cable 5 and the isolated dual power supply 1, avoiding the line from falling off or the connection from loosening, resulting in unstable power supply of the isolated dual power supply 1 or other problems.

[0025] The sizes of the slide groove 82 and the slider 83 match. When the bidirectional threaded rod 85 rotates to drive the slider 83 to move up and down inside the slide groove 82, the slide groove 82 can limit the slider 83 to prevent the slider 83 from shaking during the sliding process and affecting the squeezing and fixing of the cable 5 by the pressure plate 84.

[0026] The protection assembly 9 includes a protection sleeve 91 fixedly connected to the fixing frame 81, the protection sleeve 91 is a plastic telescopic sleeve, a connecting block 92 fixedly connected to the protection sleeve 91, a positioning rod 93 fixedly connected to the connecting block 92, a spring groove 94 provided on the positioning rod 93, a spring 95 fixedly connected to the spring groove 94, a top bead 96 fixedly connected to one end of the spring 95, a positioning hole 97 provided on the isolated dual power supply 1, and a clamping hole 98 provided on the positioning hole 97. The sizes of the positioning rod 93 and the positioning hole 97 match each other. After the pressing plate 84 fixes the cable 5, the protection sleeve 91 is pulled through the connecting block 92. The connection between the cable 5 and the isolated dual power supply 1 is covered, and the positioning rod 93 is allowed to enter the positioning hole 97. At this time, the inner wall of the positioning hole 97 will squeeze the top bead 96 and the spring 95 to slide inside the spring groove 94. When the positioning rod 93 completely enters the positioning hole 97, the spring 95 resets and pushes the top bead 96 into the card hole 98, completing the fixation of the positioning rod 93, and then completing the fixation of the protective cover 91. The protective cover 91 can protect the connection between the cable 5 and the isolated dual power supply 1 to prevent dust or other debris from falling on the surface of the connection and affecting the connection between the cable 5 and the isolated dual power supply 1.

[0027] Working principle: Pass the bidirectional threaded rod 85 between the two sets of pressure plates 84, and then rotate the rotating block 86 to drive the bidirectional threaded rod 85 to rotate. At this time, the slider 83 threadedly connected to the bidirectional threaded rod 85 will slide up and down inside the slide groove 82 and drive the pressure plate 84 to squeeze and fix the cable 5, thereby ensuring the stability of the connection between the cable 5 and the isolated dual power supply 1.
