Description

Technical Field

[0001] This invention belongs to the field of busbar technology, specifically relating to a data center busbar copper busbar fixing device and connecting device. Background Technology

[0002] In data center power distribution systems, busbar trunking is a critical device for high-current transmission. When two busbar trunkings are connected, the fixing of the copper busbars and the installation structure of the connector side plates and covers directly affect the reliability and assembly efficiency of the equipment. Currently, separate component solutions are commonly used for fixing the copper busbars and installing the connector side plates and covers. Specifically, two side plate mounting components and two cover plate mounting components need to be installed around the busbar housing to assemble and fix the connector side plates and covers; while the fixing of the copper busbars relies on four independent copper busbar fixing components.

[0003] The existing solution has the following shortcomings in practical applications:

[0004] 1. The number of parts is large and the installation process is complicated. Multiple scattered and independent parts need to be assembled in sequence, which is time-consuming, inefficient and increases labor costs.

[0005] 2. Holes need to be made in the busbar casing to fix the above-mentioned mounting parts. Making holes will damage the overall sealing of the casing, reduce the protection level of the product, and also affect the overall appearance and aesthetics of the equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a data center busbar copper busbar fixing device and connection device, which has a simple structure, is easy to install, and does not affect the protection performance.

[0007] The first aspect of the present invention provides a data center busbar copper busbar fixing device, comprising:

[0008] The first fixing member is a frame structure, and the second fixing members are installed on the first fixing member and the two second fixing members are arranged longitudinally symmetrically. Each second fixing member surrounds one side of the first fixing member to form multiple slots through which copper busbars pass and which are mutually insulated.

[0009] The second fixing member has multiple limiting protrusions, one limiting protrusion corresponding to one slot, the limiting protrusions extending toward the slot, and when there is a copper busbar in the slot, the limiting protrusions abut against the copper busbar; the first fixing member and the second fixing member are insulators.

[0010] In one embodiment, the first fastener has first mounting holes at the top and bottom for securing the connector cover plate, and second mounting holes on both sides for securing the connector side plate.

[0011] In one embodiment, the first fixing member has a crossbar and a support column, with each end of the crossbar connected to one of the support columns. The end of the crossbar or the top of the support column is provided with a first snap-fit ​​portion. The top of the second fixing member is provided with a first fastening portion, which engages with the first snap-fit ​​portion. The bottom of the support column is provided with a second snap-fit ​​portion, and the second fixing member is provided with a second fastening portion that engages with the second snap-fit ​​portion.

[0012] In one embodiment, the first latching part is a trapezoidal boss arranged laterally, and the side of the boss adjacent to the support column has an inclined surface; the second latching part is a cylindrical platform, and the side of the cylindrical platform adjacent to the support column has an inclined surface.

[0013] In one embodiment, both the boss and the cylindrical platform are provided with a first through hole, and the second fixing member has a second through hole that mates with the first through hole. The first through hole mates with the mounting hole at the end of the data center bus.

[0014] In one embodiment, the inner wall of the support adjacent to the boss or the cylindrical platform is recessed outward to form a first limiting platform and a second limiting platform, respectively, and the top and bottom of the second fixing member at least partially abut against the first limiting platform and the second limiting platform, respectively.

[0015] In one embodiment, the support has an extension arm located below the cylindrical platform, the extension arm intersecting with the cylindrical platform to form a clearance space for the PE copper busbar to pass through.

[0016] In one embodiment, the support has a first isolation protrusion and the second fastener has a second isolation protrusion, the first isolation protrusion abutting against the second isolation protrusion to isolate two adjacent slots.

[0017] In one embodiment, the lower part of the first fastener has an opening; the first fastener is made of an insulating and flame-retardant material;

[0018] And / or,

[0019] The first isolation protrusion has a third through hole, and the second isolation protrusion has a fourth through hole. The third through hole and the fourth through hole cooperate with each other, and the third through hole is a countersunk hole.

[0020] A second aspect of the present invention provides a data center busbar connection device, comprising: two copper busbar fixing devices as described above and a connector, wherein the two ends of the cover plate and side plate of the connector are respectively mounted on a copper busbar fixing device and enclose to form a connection cavity, and the connector is used to connect the copper busbars of two data center buses in the connection cavity.

[0021] The technical solution provided by this invention has the following advantages and effects:

[0022] A slot is formed by a frame-shaped first fixing member and two second fixing members, through which the copper busbar of the data center busbar passes. The limiting protrusions of the second fixing members further limit the copper busbar within the slot. Together, the limiting protrusions and the slot effectively fix the copper busbar. The structure is simple, easy to install, and does not affect the protective performance. Attached Figure Description

[0032] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0033] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0034] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0035] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0036] like Figure 1-4 As shown, the data center busbar copper busbar fixing device of this embodiment includes: a first fixing member 10 and two second fixing members 20. The first fixing member 10 is used to install at the end of the data center busbar 100. The first fixing member 10 has a frame-like structure with a bottom opening but not a restriction, and includes a crossbar 11 and two support columns 12. The crossbar 11 and the support columns 12 are integrally formed, and the two ends of the crossbar 11 are connected to the support columns 12. The second fixing members 20 have a strip-like structure, and the two second fixing members 20 are each installed on one side of the first fixing member 10, and the two second fixing members 20 are arranged symmetrically in the longitudinal direction. Each second fixing member 20 surrounds the left or right side of the first fixing member 10 to form two slots 30 through which the copper busbar passes and are mutually insulated. By setting the first fixing member 10 and the two second fixing members 20, the total number of copper busbar fixing members is reduced from the existing 4 to 3, reducing material costs, facilitating installation, and improving installation efficiency. The first fixing member 10 and the second fixing members 20 are made of insulating material. Since the first fastener 10 is located on the outside, the material of the first fastener 10 is preferably an insulating and flame-retardant material, such as flame-retardant nylon (PA6 / PA66), polyphenylene sulfide (PPS), flame-retardant polyphenylene ether (PPO / PPE), flame-retardant PBT, etc.

[0037] The second fastener 20 has multiple limiting protrusions 21, each corresponding to a slot 30, and the limiting protrusions 21 extend toward the slot 30. When there is a copper busbar inside the slot 30, the limiting protrusions 21 abut against the copper busbar, thus limiting the copper busbar inside the slot 30. The limiting protrusions 21 and the slot 30 work together to effectively fix the copper busbar.

[0038] To facilitate installation between the second fixing member 20 and the first fixing member 10 and to limit their relative displacement, the second fixing member 20 is installed on the first fixing member 10 using a top and bottom fastening method. Specifically, a first locking part 13 is provided at the end of the crossbar 11 or the top of the support column 12 (in this embodiment, at the end of the crossbar), and a first fastening part 22 is provided at the top of the second fixing member 20. The first fastening part 22 fastens onto the first locking part 13, forming the upper fixing point. A second locking part 14 is provided at the bottom of the support column 12, and a second fastening part 23 is provided on the second fixing member 20 to cooperate with the second locking part 14, forming the lower fixing point. The second fixing member 20 is assembled onto the first fixing member 10 through the two fixing points.

[0039] The specific shapes of the first engaging part 22, the second engaging part 23, the first latching part 13, and the second latching part 14 are not limited, but preferably, the structure is as described in this embodiment: the first latching part 13 is a horizontally arranged trapezoidal boss 131, and the side of the boss 131 adjacent to the support column 12 has an inclined surface; the first engaging part 22 is a right-angled trapezoidal groove 221, which can be engaged with the boss 131, and the inclined surface of the groove 221 is in contact with the inclined surface of the boss 131. The second latching part 14 is a cylindrical platform 141, and the side of the cylindrical platform 141 adjacent to the support column 12 has an inclined surface. The second engaging part 23 is also a right-angled trapezoidal groove 231, which can be fitted onto one end of the cylindrical platform 141, and the inclined surface of the groove 231 is in contact with the inclined surface of the cylindrical platform 141. The upper trapezoidal boss 131, the lower cylindrical platform 141, and the inclined surface are fitted together to enhance the stability of the second fastener 20 when it is installed on the first fastener 10.

[0040] This embodiment also integrates and optimizes the structure of the second fixing member 20 installed on the first fixing member 10 and the structure of the first fixing member 10 installed on the data center bus 100. Specifically, a first through hole 15 is provided on both the boss 131 and the cylindrical platform 141. The second fixing member 20 has a second through hole 24 that mates with the first through hole 15. The first through hole 15 mates with the mounting hole (not shown in the figure) at the end of the data center bus 100. During installation, a fastener passes through the second through hole 24, the first through hole 15, and the mounting hole in sequence, which can realize the connection and reinforcement between the second fixing member 20 and the first fixing member 10, and at the same time fix the entire copper bus fixing device to the end of the data center bus.

[0041] To enhance the longitudinal limiting capability of the second fastener 20 when it is installed on the first fastener 10, the inner wall of the support column 12 adjacent to the boss 131 or the cylindrical platform 141 is recessed outward to form a first limiting platform 121 and a second limiting platform 122, respectively. The top of the second fastener 20 at least partially abuts against the first limiting platform 121, and the bottom of the second fastener 20 at least partially abuts against the second limiting platform 122. The first limiting platform 121 and the second limiting platform 122 respectively limit downward or upward movement, thereby enhancing the stability of the copper busbar fixation.

[0042] In this embodiment, the support column 12 has a first isolation protrusion 123 extending toward the second fixing member 20. The second fixing member 20 has a second isolation protrusion 25 extending toward the support column 12. The first isolation protrusion 123 and the second isolation protrusion 25 abut against each other to isolate two adjacent slots 30. This structural design simplifies the molding of the copper busbar fixing device. It should be noted that the method of achieving mutual insulation and isolation between slots 30 is not limited to this.

[0043] Furthermore, the first isolation protrusion 123 has a third through hole 1231, and the second isolation protrusion 25 has a fourth through hole 251. The third through hole 1231 and the fourth through hole 251 cooperate to install the fastener on the third through hole 1231 and the fourth through hole 251, thereby enhancing the installation reliability between the first fixing member 10 and the second fixing member 20. Preferably, the third through hole 1231 is a countersunk hole, so that the fixing screw is recessed into the mounting surface, which not only improves the appearance but also reduces the space occupied by the screw head.

[0044] This embodiment also integrates functions and simplifies the structure of the copper busbar fixing device and the connector. First mounting holes 16 for fixing the connector cover plate are provided at the top and bottom of the first fixing member 10, and second mounting holes 17 for fixing the connector side plates are provided on both sides of the first fixing member 10. The first mounting holes 16 and the second mounting holes 17 are used to position and fix the connector side plates and the cover plate. This design eliminates the need for four separate side plate and cover plate mounting components, and the copper busbar fixing device can simultaneously perform the triple functions of copper busbar clamping, connector side plate positioning, and cover plate fixing.

[0045] In this embodiment, the support column 12 extends downward to form an extension arm 124. The extension arm 124 is located below the cylindrical platform 141. One end of the extension arm 124 intersects with the cylindrical platform 141. The extension arm 124 and the cylindrical platform 141 form a clearance space 40 for the PE copper busbar to pass through.

[0046] In summary, the copper busbar fixing device of this embodiment integrates the originally separate functions of copper busbar fixing, side plate support and cover plate locking into the same set of fixing components. It has a simple structure, is easy to install, and does not require additional holes to be made on the main body of the outer casing, thus improving the overall protection performance of the data center busbar casing.

[0047] This invention also provides a data center busbar connection device, comprising: two copper busbar fixing devices and a connector, wherein the two ends of the cover plate and side plate of the connector are respectively mounted on a copper busbar fixing device and enclose to form a connection cavity, and the connector connects the copper busbars of the two data center buses within the connection cavity.

[0048] The purpose of the above embodiments is to reproduce and derive the technical solution of the present invention by way of example, and to fully describe the technical solution, purpose and effect of the present invention. The purpose is to enable the public to have a more thorough and comprehensive understanding of the disclosure of the present invention, and not to limit the scope of protection of the present invention.

[0049] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
