Description

Technical Field

[0001] This utility model relates to the field of switch connection equipment technology, and more specifically, to a ruggedized switching power supply adapted to switches. Background Technology

[0002] In general, the front panel of a switch typically consists of, from left to right, a status indicator light, several vertically arranged Ethernet ports for connecting network cables, a reset button, a management interface, and a USB port. The rear panel consists of, from left to right, a grounding wire, a redundant power supply interface, and a power interface. The redundant power supply interface connects to an external power source, and the power supply is controlled by a chip for load balancing. When one power supply fails, the other power supply can immediately take over its operation. After the power supply is replaced, the two power supplies work together again. The redundant power supply is designed to achieve high availability of the switch system.

[0003] For the aforementioned switch structure, they are generally arranged at different heights and installed on mounting plates with mounting slots at the front and rear ends on both sides inside the cabinet. For switches located at lower positions in the cabinet, the power plugs are easy to connect. However, for switches located at higher positions in the cabinet, the power cords below the power plugs are longer, requiring a considerable length to be raised for connection. After prolonged use, under the weight of the power cords, redundant power interfaces and power plugs are prone to detachment. Furthermore, the twisting degree and twisting force at the junction of the power cord and the plug are relatively high, making the power cord in this area prone to damage. Utility Model Content

[0004] The purpose of this invention is to provide a ruggedized switching power supply adapted to switches. This ruggedized switching power supply can reinforce the redundant power interfaces and power plugs of existing switches, solving the problem that power plugs of switches located high inside the cabinet are prone to falling off, avoiding wire twisting at the junction of the power cord and the plug, and maintaining the long-term stable operation of the switch.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ruggedized switching power supply adapted to a switch includes a switch, which is fixed to the through slots of the front and rear mounting plates on both sides of a cabinet by screws. The rear side of the switch is provided with a grounding wire, a redundant power interface, and a power interface. A DC power plug and a three-prong plug are respectively inserted into the redundant power interface and the power interface. Symmetrical clamping plates are provided at the top and bottom of both sides of the switch, and the clamping plates at the top and bottom of the same side are all fitted onto the guide rod. Baffles are fixed at the top and bottom of the guide rod. A tensioning spring is fitted onto the guide rod between the symmetrical clamping plates. The clamping plates are embedded into the through slots on the top and bottom sides through concave clamping slots. The clamping plates at the same height on the left and right sides are connected by clamping strips. Several concave limiting clamping frames and H-shaped limiting clamping frames are clamped on the clamping strips.

[0007] As a further optimization of this solution, the inner side of the concave limiting card frame and the H-shaped limiting card frame, where they meet the card strip, are all machined with card teeth of quarter-circle cross-section arranged at equal intervals. The concave limiting card frame is respectively fitted into the two planar areas on both sides of the DC power plug and the three-prong plug.

[0008] As a further optimization of this solution, the outer end of the H-shaped limiting frame is connected to a vertical threaded rod. A support rod is installed on the body of the threaded rod by upper and lower nuts, and the support rod supports the power cord of the DC power plug and the three-prong plug upwards.

[0009] As a further optimization of this solution, the card strips are located at the top and bottom of the rear side of the switch, respectively.

[0010] As a further optimization of this solution, the concave limiting card frame and the H-shaped limiting card frame adjust the interval distance with the card strip by clamping the card teeth at different positions.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model incorporates a movable upper and lower clamping plate structure, which facilitates the installation of clamping strip structures on the existing mounting plate through slots. The clamping strip structure is used to install concave limiting clamping frames, which are respectively clamped onto the two flat areas on both sides of the DC power plug and the three-prong plug, thereby achieving reinforcement of the DC power plug and the three-prong plug. This solves the problem of power plugs of switches located high inside the cabinet easily falling off, and improves connection stability.

[0013] In this invention, an H-shaped limiting frame is installed using a clip structure, combined with an adjustable height support rod structure. This supports the outer side of the line at the junction of the power cord and the plug, flattens the easily twisted inner area of ​​the line, prevents the line from twisting at the junction of the power cord and the plug, and maintains the stable operation of the switch for a long time.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the issue that the power cord 15 below the power plug of the switch 3 located at a higher position in the existing cabinet 1 is relatively long, requiring a considerable length to be raised for connection, and that after prolonged use, the power plugs of the redundant power interface 22 and power interface 21 are prone to detachment under the weight of the power cord 15, and that the twisting degree and twisting force at the junction of the power cord 15 and the plug are relatively high, making the power cord 15 in this area prone to damage.

[0021] like Figure 1 As shown, this application includes a switch 3, which is fixed to the through slots 11 of the front and rear mounting plates 2 on both sides of the cabinet 1 by screws.

[0022] like Figure 2 and Figure 4As shown, the rear side of the switch 3 is provided with a grounding wire 4, a redundant power interface 22 and a power interface 21. A DC power plug 5 and a three-prong plug 6 are respectively inserted into the redundant power interface 22 and the power interface 21. Symmetrical card plates 7 are provided on the upper and lower ends of both sides of the switch 3, and the card plates 7 on the same side are all fitted onto the guide rod 8. Baffles 9 are fixed on the upper and lower ends of the guide rod 8. A clamping spring 10 is fitted onto the guide rod 8 between the symmetrical card plates 7. The card plates 7 are embedded into the through slots 11 on the upper and lower sides through the concave card slots 20. Card strips 12 are connected between the card plates 7 at the same height on the left and right. Several concave limit card frames 13 and H-shaped limit card frames 14 are clamped on the card strips 12.

[0023] like Figure 3 As shown, the inner surfaces of the concave limiting card frame 13 and the H-shaped limiting card frame 14 are machined with card teeth 16 of quarter-circle cross-section arranged at equal intervals at the junction with the card strip 12. The concave limiting card frame 13 is respectively attached to the two planar areas of the DC power plug 5 and the three-prong plug 6.

[0024] The outer end of the H-shaped limiting frame 14 is connected to a vertical threaded rod 17. The rod body of the threaded rod 17 is limited and installed with a support rod 19 by upper and lower nuts 18. The support rod 19 supports the power cords 15 of the DC power plug 5 and the three-prong plug 6. The locking strips 12 are located above and below the rear side of the switch 3, respectively.

[0025] Specifically, the operator uses both hands to press the upper and lower end clips 7 inwards, moving them away from the upper and lower end baffles 9. The clips 7 are then inserted into the through slots 11 on both sides of the switch 3. Next, the slots 20 of the clips 7 are aligned and embedded into the through slots 11, with the width of the slots 20 matching the width of the through slots 11. The clips 7 are then released, and under the elastic force of the tension spring 10, they are pushed outwards, allowing the slots 20 to be stably embedded and fixed inside the through slots 11. The clips can be adjusted according to the positions of the DC power plug 5 and the three-prong plug 6 at the rear of the switch 3. A concave limiting frame 13 is inserted into the strip 12. The concave limiting frame 13 is respectively installed on the two sides of the DC power plug 5 and the three-prong plug 6 to achieve a reinforcement effect. At the same time, an H-shaped limiting frame 14 is installed on the strip 12 on one side of the DC power plug 5 and the three-prong plug 6. The height of the support rod 19 on the threaded rod 17 is adjusted by the nut 18 so that the support rod 19 supports the outside of the line at the junction of the power cord 15 and the plug, flattening the easily twisted line area on the inside, avoiding the twisting of the line at the junction of the power cord 15 and the plug, and maintaining the stable operation of the switch for a long time.
