Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary devices for communication equipment, specifically relating to a power supply redundancy parallel connection bracket for a switch. Background Technology
[0002] With the rapid development of communication technology, switches, as core devices for data transmission and switching, directly affect the operating efficiency of the entire communication network due to the stability and reliability of their power supply systems. To meet the zero-interruption requirements under high-load scenarios, switches typically adopt a redundant parallel design with multiple power supply modules. This means that multiple power supply modules work simultaneously, and when a single module fails, the remaining modules can seamlessly replenish power, preventing system downtime.
[0003] Traditional brackets use series copper busbar connections, requiring multiple modules to pass through multiple transfer points for current aggregation. When a single module fails, the power supply path for the remaining modules is delayed due to the numerous transfer points, failing to meet the millisecond-level switching requirements of zero-interruption switches. Power module interfaces are mostly symmetrical structures with no directional guidance during insertion. If the polarity is reversed, repeated insertion and removal adjustments are required, which not only prolongs installation time but may also cause terminal wear or short circuits due to misoperation. Therefore, a redundant parallel connection bracket for switch power supplies has emerged. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example
[0018] Reference Figures 1-6 This embodiment of the present invention provides a power supply redundancy parallel connection bracket for a switch, comprising: The support mechanism 100 includes a support foot 101, a base plate 102 fixedly installed on the top of the support foot 101, a support column 103 fixedly installed on the surface of the base plate 102, a horizontal plate 104 movably installed on the side wall of the support column 103, and a top plate 105 fixedly installed on the top of the support column 103. The power module adapter mechanism 200 includes a terminal block assembly 201 movably mounted on the surface of the base plate 102, a power mounting box 202 movably mounted on the surface of the base plate 102, a snap-fit terminal 203 fixedly mounted on the end of the power mounting box 202, a limiting assembly 205 fixedly mounted on the top of the power mounting box 202, a cable management tray assembly 206 movably mounted on the top of the power mounting box 202, and an anti-misinsertion assembly 207 fixedly mounted on the inner wall of the power mounting box 202. The terminal block assembly 201 includes a base 201a fixedly mounted on the surface of the base plate 102, a copper busbar 201b movably mounted in a groove on the surface of the base 201a, a wire clamping frame 201c movably mounted on the upper surface of the base 201a, and a screw 201d disposed in the wiring channel of the wire clamping frame 201c.
[0019] The power supply mounting box 202 consists of three rectangular cavities arranged side by side, which are fixedly mounted on the surface of the base plate 102 by bolts. The number of wiring ports of the terminal block assembly 201 is greater than the number of snap-fit terminals 203. The limiting assembly 205 is fixedly mounted on the top of the power supply mounting box 202. The redundant power supply sidewall has corresponding grooves. The anti-misinsertion assembly 207 consists of two sets, which are symmetrically arranged at the front end of the inner sidewall of the power supply mounting box 202.
[0020] Specifically, the anti-misinsertion component 207 includes a fixing block 207a fixedly installed on the inner wall of the power supply mounting box 202, a guide block 207b hinged to the fixing block 207a via a pin, and a tension spring 207c with one end connected to the inner wall of the power supply mounting box 202 and the other end connected to the guide block 207b.
[0021] Furthermore, a triangular metal block is provided at one end of the guide block 207b, and a rectangular block is provided at the other end. An anti-slip pad is fixedly attached to the end of the rectangular block. When the power module is inserted in the correct direction, the guide groove on the side of the module and the guide block 207b are fitted together to allow the module to pass smoothly. If the module is inserted in reverse, its side will press down on the triangular metal block at one end of the guide block 207b, and the rectangular block at the other end of the guide block 207b will rise and lock the power module, thus realizing the function of preventing misinsertion.
[0022] Preferably, the base 201a has two symmetrical grooves on its top and threaded holes, and the copper busbar 201b has a protrusion at its bottom that matches the grooves. The protrusion and groove engage with the base 201a. The wire clamping frame 201c has a through hole that corresponds to the threaded hole of the base 201a. The fastening screw passes through the through hole of the wire clamping frame 201c and screws into the threaded hole of the base 201a, thus fixing the wire clamping frame 201c to the base 201a.
[0023] It should be noted that the two grooves on the surface of the base 201a are parallel rectangular grooves, and there are 8 threaded holes at both ends of the base between the grooves for fixing the wire frame 201c. The bottom of the copper busbar 201b is provided with a rectangular protrusion that matches the rectangular groove. The protrusion is clamped to the base by the interference fit between the groove and the groove to prevent the copper busbar from loosening.
[0024] In use, the four support feet 101 are vertically fixed to the four corners of the lower surface of the base plate 102 with screws. The bottoms of the four support columns 103 are aligned with the mounting holes on the upper surface of the base plate 102. The top plate 105 is placed over the top of the support columns. The bolts of the horizontal plate 104 are inserted into the oblong holes on the side walls of the support columns 103. The protrusions of the copper busbar 201b are pushed into the rectangular groove of the base 201a. The wire clamp frame 201c is fastened, aligning the through hole with the threaded hole of the base. The screws are then tightened. The assembled terminal block assembly 201 is fixed to the left side of the upper surface of the base plate 102 with screws. The three power mounting boxes 202 are fixedly installed on the surface of the base plate 102. The power module is held in hand, so that the side guide... Align the inclined surface with the anti-misinsertion component 207 inside the power installation box 202 and slowly push the module in. At this time, the guide block 207b is squeezed by the inclined surface, and the module smoothly enters the installation cavity. When the module is fully inserted, a click sound can be heard, indicating that the locking tongue 205b of the limit component 205 has been engaged in the positioning hole on the top of the module. The power connection wire 204 has one end crimped with an OT type cold-pressed terminal and is fastened to the output end of the snap-fit terminal 203 by bolts. The other end is insulated. Insert the copper core into the wiring channel of the wire crimping frame 201c of the terminal block component 201. Put the excess cable into the annular cable management groove of the cable management tray component 206. Rotate the buckle 206c so that the buckle head is embedded in the snap-fit groove 206d at the corresponding angle.
[0025] In summary, the multi-power supply mounting box 202 is connected in parallel through the terminal block assembly 201. When a single module fails, the remaining modules can be quickly powered through the copper busbar 201b, meeting the zero-interruption power supply requirements of the switch. When the power module is inserted, the anti-misinsertion component 207, through the cooperation of the guide block 207b and the tension spring 207c, avoids repeated insertion and removal due to incorrect direction. The locking tongue 205b of the limiting component 205 and the compression spring 205c achieve one-push locking, which can be fixed without tools, shortening the installation time of a single module. The annular cable management groove of the cable management tray assembly 206, in cooperation with the buckle 206c, improves the neatness of cable winding and avoids cable damage caused by traditional cable ties.
