Description

Floating assembly structure of multiple substrates

The present invention relates to a floating assembly structure, in particular to a structure for floating assembly of multiple substrates.

With the advancement of technology, multiple substrates (such as printed circuit boards) are usually installed in the cabinets of electronic equipment (such as servers or battery storage devices), and the operation of these substrates is used to improve the performance of the electronic equipment.

Traditionally, multiple substrates can also be assembled together using connectors. As shown in FIG. 1 , the electronic device 100 includes a first substrate 11 and a second substrate 12. A first connector 110 is provided on one surface of the first substrate 11, and a second connector 120 is provided on one surface of the second substrate 12. The first substrate 11 can be fixed on the inner surface of the housing 10 of the cabinet of the electronic device 100. In addition, the first substrate 11 and the second substrate 12 are assembled together through the connection of the first connector 110 and the second connector 120. For example, the second connector 120 can be a male connector, the first connector 110 can be a female connector, and the second connector 120 is plugged into the first connector 110, so that the second substrate 12 is assembled with the first substrate 11.

The first substrate 11 and the second substrate 12 are assembled in a connector manner. The tolerance between the first connector 110 and the second connector 120 must be very precise. Otherwise, the second connector 120 cannot be smoothly inserted into the first connector 110 or is easily loosened from the first connector 110 when inserted into the first connector 110.

Furthermore, the length of the current server or battery storage cabinet is getting longer and longer, and the longitudinal body is getting deeper and deeper. If the first substrate 11 is set deep in the cabinet, the second connector 120 of the second substrate 12 is not easy to align and plug with the first connector 110 of the first substrate 11. Furthermore, if the substrate carries heavy electronic components (such as data storage or battery cells), during the assembly process, the second substrate 12 must be pushed forcefully in the direction of the first substrate 11, which will cause a large impact force between the first connector 110 and the second connector 120. The large impact force may also cause damage to the structures of the first connector 110 and the second connector 120, thereby making it impossible for the second substrate 12 to be smoothly assembled with the first substrate 11.

In view of the above-mentioned problems in assembling multiple substrates using connectors, the present invention proposes a structure for floating assembly of multiple substrates so that multiple substrates can be easily assembled together.

One purpose of the present invention is to provide a floating assembly structure for multiple substrates, which includes a fixing seat, a spacer column and a limiter. The fixing seat is arranged on the inner surface of a shell, and a first boss is convexly provided on one end surface of the fixing seat. A first fixing hole is provided in the center of the first boss. A second boss is convexly provided on one end surface of the spacer column, and a first positioning rod is convexly provided on the other end surface. A second fixing hole is provided in the center of the second boss. The limiter includes a limit block and a second positioning rod perpendicular to the limit block. When the first positioning rod of the spacer column passes through a through hole of a first layer of substrate and is arranged in the first fixing hole, a first annular space is formed on the periphery of the first boss. When the second positioning rod of the stopper passes through the through hole of the second layer substrate and is set in the second fixing hole, a second annular space is formed on the periphery of the second convex column; the first layer substrate floats in the first annular space, and the second layer substrate floats in the second annular space. In this way, in the process of assembling multiple substrates with the floating assembly structure, each layer of the substrate remains in a floating state in the corresponding annular space and will not be clamped by the assembly structure. Therefore, there is no need to accurately align the floating substrates, and the assembly structure can easily assemble the substrates together to increase the convenience of assembly.

To achieve the above-mentioned purpose, the present invention provides a floating assembly structure for assembling a plurality of substrates together, each substrate including a through hole. The floating assembly structure includes: a housing; a fixing seat disposed on the inner surface of the housing, and a first protrusion protruding from one end surface of the fixing seat, wherein a first fixing hole is provided at the center of the first protrusion; a spacing column, a second protrusion protruding from one end surface of the spacing column, and a first positioning rod protruding from the other end surface, wherein a second fixing hole is provided at the center of the second protrusion ; and a stopper, including a stopper block and a second positioning rod perpendicular to the stopper block; wherein, when the first positioning rod of the spacer column passes through the corresponding through hole of the substrate and is disposed in the first fixing hole, a first annular space is formed on the periphery of the first protruding column; when the second positioning rod of the stopper passes through the corresponding through hole of the substrate and is disposed in the second fixing hole, a second annular space is formed on the periphery of the second protruding column; one substrate floats in the first annular space, and the other substrates float in the second annular space.

In one embodiment of the present invention, the diameter of the spacer column is D1, the diameter of the through hole of the substrate is D2, the diameter of the first protrusion is D3, and D1>D2>D3.

In one embodiment of the present invention, the diameter of the spacer column is D1, the diameter of the through hole of the substrate is D2, and the diameter of the second protrusion is D4, D1>D2>D4.

In one embodiment of the present invention, the fixing seat is a nail, and the limiting member is a screw.

In one embodiment of the present invention, the first positioning rod and the second positioning rod are respectively arranged in the first fixing hole and the second fixing hole in a locking manner.

The present invention also provides a floating assembly structure for assembling a plurality of substrates together, each substrate including a through hole. The floating assembly structure includes: a shell; a fixing seat, which is disposed on the inner surface of the shell, and a first boss is convexly provided on one end surface of the fixing seat, wherein a first fixing hole is provided at the center of the first boss; a plurality of spacer columns, each of which has a second boss convexly provided on one end surface and a first positioning rod convexly provided on the other end surface, wherein a second fixing hole is provided at the center of the second boss; and a limiting member, including a limiting block and a second positioning rod perpendicular to the limiting block; wherein the first positioning rod of each spacer column passes through the through hole of the corresponding substrate and is disposed on the first fixing hole of the fixing seat. The first fixing hole of the spacer column or the second fixing hole of another spacer column is set, and the second positioning rod of the limiting member passes through the through hole of the corresponding substrate and is set in the second fixing hole of one of the spacer columns; wherein, when the first positioning rod of one of the spacer columns is set in the first fixing hole of the fixing seat, a first annular space is formed on the periphery of the first protrusion; when the first positioning rod of the other spacer column is set in the second fixing hole of another spacer column or the second positioning rod of the limiting member is set in the second fixing hole of one of the spacer columns, a second annular space is formed on the periphery of the second protrusion of each spacer column; one of the substrates will float in the first annular space, and the other substrates will float in the second annular space.

As shown in Figures 2, 3 and 4, the floating assembly structure of this embodiment is used to assemble multiple substrates (such as two-layer substrates) 20 together, which includes a fixing seat 31, a spacer column 33 and a stopper 35. Among them, the substrate 20 can also be a printed circuit board, and each layer of the substrate 20 is provided with at least one through hole 201.

The fixing seat 31 is disposed on the inner surface of a housing 40. In one embodiment of the present invention, the housing 40 is a cabinet housing of an electronic device, and the fixing seat 31 is a cylindrical implant fixed on the inner surface of the cabinet housing.

In one embodiment of the present invention, the first positioning rod 342 and the second positioning rod 352 are rods with external threads, and the first fixing hole 321 and the second fixing hole 341 are holes with internal threads. The first positioning rod 342 of the spacer column 33 and the second positioning rod 352 of the stopper 35 are respectively arranged in a locking manner in the first fixing hole 321 of the first boss 32 and the second fixing hole 341 of the second boss 34.

When the first positioning rod 342 of the spacer rod 33 is disposed in the first fixing hole 321 of the first protruding column 32 of the fixing seat 31, a first annular space 320 is formed on the periphery of the first protruding column 32. When the second positioning rod 352 of the stopper 35 is disposed in the second fixing hole 341 of the second protruding column 34 of the spacer rod 33, a second annular space 340 is formed on the periphery of the second protruding column 34.
