Detailed Description

At present, more and more computer equipment are arranged in a data center, a very high requirement is placed on the high integration level of the computer equipment, and if the integration level of the computer equipment is higher, the computational density is higher, the operation cost of the data center can be obviously reduced. More boards are placed in a subrack to increase integration.

The multiple single boards in one machine frame need to be connected with each other through connectors to transmit signals. This brings a problem that when a plurality of single boards are connected in an inter-fitting manner, the butt joint dislocation occurs, which causes problems of connector back-stitching, poor connector inter-fitting, poor signal, and the like.

In the prior art, it is common to adopt a guide pin to cooperate with a guide sleeve to correct the butt joint dislocation of the connector. As shown in fig. 1, 102 and 104 are two connectors that mate with each other, referred to as a connector pair, on the second board 110 and the first board 112, respectively. The guide pin 106 is fixed on the second single plate 110, and the guide sleeve 108 is fixed on the first single plate 112. When the first single board 112 and the second single board 110 are in butt joint through the connectors 102 and 104 and are in butt joint dislocation, the guide pin 106 and the guide sleeve 108 are in butt joint dislocation at the same time, and then a corrective force is generated on the guide sleeve 108, the first single board 112 will shift according to the direction of the corrective force, so as to correct and reduce the butt joint dislocation between the connectors 102 and 104, and finally, the normal butt joint of the connectors 102 and 104 is realized.

However, the guide pin 106 and the guide sleeve 108 have limited guiding ability, and belong to a coarse guiding tool, along with the higher and higher signal rate on the connector, the requirement of connector butt joint dislocation accurate reading is higher and higher, and the tolerance capability of the connector is smaller and smaller, and the technical scheme of the guide pin guide sleeve cannot meet the requirement of high-speed connector interworking on tolerance control, which causes the problems of poor contact, poor signal quality and reduced signal rate when the connectors are butted.

The application provides a feasible technical scheme, and the problem that the requirement on the mutual matching tolerance between multiple single boards is higher and higher is effectively solved. Embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the multiple single boards described in this application are butt-jointed by two or more single boards.

Fig. 2 is a schematic diagram of a floating assembly 200 according to an embodiment of the present application, where the floating assembly 200 includes the following components: a fixed seat 208, a sliding module 206, two limit blocks 202 and two elastic structures 204. Fixing base 208 is fixed on the handle strip, and slide module 206 is installed on fixing base 208, with fixing base 208 sliding connection. The sliding module 206 can slide along a first direction relative to the fixed seat 208, and the first direction is parallel to the long side of the floating assembly 200 in this embodiment. The first board is fixed on the sliding module 206 and can slide together with the sliding module 206 in the first direction relative to the fixing base 208.

The limit blocks 202 are fixed at two ends of the fixing base 208, and can limit the sliding range of the sliding module 206 not to exceed the fixed position of the limit blocks 202. This is done to prevent the first veneer fixed on the sliding module 206 from sliding beyond the range and then colliding with other structural members or veneers to interfere with the machine frame and prevent the sliding module 206 from sliding off the entire floating assembly 200.

For example, the sliding module 206 in this embodiment may be provided with 2 positioning pillars 212 and 6 supporting pillars 210. When the first single board is mounted on the sliding module 206, the positioning column 212 passes through the positioning hole on the first single board, so that the relative position between the first single board and the sliding module 206 can be determined, and the support column 210 supports the first single board. Each support post 210 has a threaded hole 214, and a screw is threaded through the threaded hole of the first plate and screwed into the threaded hole 214 of the support post 210, thereby fixing the first plate to the sliding module 206. It will be appreciated that screws and threaded holes are one possible way to secure the first veneer to the slide module 206, and that there are other fasteners that can accomplish this, including: screws, nuts, studs, buckles, and the like.

In this embodiment, the elastic structure 204 is located between the limiting block 202 and the sliding module 206, and is located in the elastic structure cavity at two ends of the sliding module.

Fig. 3 further illustrates a detailed structure of a part of the floating assembly 200 in this embodiment, and it can be seen from fig. 3 that the limiting block 302 and the fixing seat 304 are fixed by a screw 304. One end of the sliding module 310 is disposed in the sliding module cavity 314 of one of the stop blocks 302. it can be easily understood that the other end of the sliding module 310 is also disposed in the sliding module cavity 314 of the other stop block 302. The sliding module 310 is constrained by the sliding module cavity 314, the sliding range does not exceed the sliding module cavity 314, and the sliding module 310 can be prevented from being separated from the whole floating module 200.

The resilient structure 306 is disposed in a resilient structure cavity 312 between the stop block 302 and the sliding module 310. the resilient structure 306 may be secured to either the stop block 302 or the sliding module 310. The elastic structure 306 is used to make the upper layer of the sliding module 310 to be at the initial position relative to the fixing base 308 without being subjected to an external force, and at the same time, make the first single board fixed on the sliding module 310 to be at the initial position relative to the fixing base 308. The purpose of this is to make the first single board and the second single board in the optimal butt joint position of the structural design when the first single board is in butt joint with the second single board.

The elastic structure 306 may include a spring, a disk, a memory metal, etc. The elastic structure 306 can control the sliding speed of the sliding module 310 so as to prevent the sliding module 310 and the stopper 302 from colliding with each other, which results in a decrease in the stopping accuracy of the stopper.

In addition, the limiting block 302 has a slot, the supporting column 316 of the sliding module 310 passes through the slot, the screw passes through the first single plate and is screwed into the screw hole 318, so as to fix the first single plate to the sliding module 310.

Fig. 4 further illustrates the form of the sliding module 402 mounted on the fixing base 406, and one possible implementation manner, as shown in the dovetail design in the figure, the sliding module 402 is designed with a wedge-shaped groove, the fixing base 406 is designed with a wedge-shaped protruding structure, the two structures can be engaged with each other, and the wedge-shaped groove of the sliding module 402 can hold the wedge-shaped protruding structure of the fixing base 406 to prevent falling off. While the sliding module 402 may also slide in the first direction. In another possible implementation, the mounting form may be a dovetail groove form or an inverted triangle form, etc. It can be easily understood that any mounting form that allows the sliding module 402 to be mounted on the fixing base 406 and to slide relatively in the first direction belongs to the technical solutions of the present application.

Fig. 6 shows a possible embodiment of the present application, which includes a first board 604, a first connector 606, a second board 610, a second connector 608, a floating component 612, and a handle bar 602. Where a first connector 606 is disposed on a first board 604 and a second connector 608 is disposed on a second board 610. The floating assembly 612 is fixed to the handle bar 602, and the first single plate 604 is fixed to the floating assembly 612. as further explained, the first single plate 604 is fixed to the sliding module 206 of the floating assembly 612. It should be noted that the second board 610 is fixed in position and does not move.

When the first board 604 and the second board 610 are mated, i.e., the first connector 606 and the second connector 608 are mated, there is a mating tolerance Δ d. In the embodiment, the floating assembly 612 has a floating capability relative to the handle bar 602, and the first single board 604 is fixed on the floating assembly 612, so that the floating capability relative to the handle bar 602 is also provided, when the first connector 606 and the second connector 608 are misaligned, a corrective force is generated on the first single board 604, the corrective force is transmitted to the first single board 604 and fixed on the sliding module 206, the sliding module 206 slides in a corresponding direction according to the direction of the corrective force, so as to correct the position, the misalignment between the first connector 606 and the second connector 608 is reduced, and the first single board 604 and the second single board 610 are normally abutted.

Fig. 5 is a block diagram of another possible embodiment 500 of the present application, where the block diagram 500 includes 3 pairs of boards in a total of the inter-connected relationship. A first board a504, a second board a506, a connector pair a502, and Δ d _ a representing the interfitting tolerances produced on connector pair a502, respectively; a first board B512, a second board B508, a connector pair B510, and the mating tolerance generated on the connector pair B510 is denoted by Δ d _ B; first board C518, second board C514, connector pair C516, and the resulting interfitting tolerance on connector pair C516 is denoted by ad _ C.

First panel a504, first panel C518, and floating assembly 513 are all secured to handle bar 520, and handle bar 520 is a rigid structural member for carrying and mounting either the first panel or the second panel. Because the handle bar 520 is a rigid structure, the positions of the three relative to the handle bar 520 are fixed, and further, the relative positions of the three are fixed. Wherein the first veneer B512 is fixed on the floating assembly 513 and the floating assembly 513 is fixed on the handle bar 520. Connector pair C516 is a rigid mating when first board C518 and second board C514 are in a fixed position, and connector pair a502 is a rigid mating when first board a504 and second board a506 are in a fixed position. While first board B512 and second board B508 are floating mounted, connector pair B510 is a floating mating. Because of the tolerance stack-up effect, the sum of the tolerances accumulated at connector pair B512 is Δ d _ total ═ Δ d _ a +/Δ d _ B +/Δ d _ C. From the calculation results, it can be seen that the mating tolerance of the connector pair B512, which needs to be cancelled, will be significantly improved, and if the conventional rigid mating manner is used, the backstitch of the connector pair B512 is easily caused, so that the whole computer device is damaged; or the contact is poor, the high-speed signal rate between single boards is reduced, and the computer equipment is not available.

In the present embodiment, the floating assembly 513 has a floating capability with respect to the handle bar 520, and the first board B512 is fixed to the sliding module of the floating assembly 513, further described, is fixed to the sliding module 206 of the floating assembly 513, and thus has the same floating capability as the floating assembly 513. When the first board B512 is in butt joint with the second board B508 and the butt joint is dislocated, the male head and the female head of the connector pair B512 are similarly dislocated, the butt joint dislocation generates a corrective force on the first board B512, the corrective force is transmitted to the sliding module 206 fixed together with the first board B512, the sliding module 206 performs corresponding sliding and position correction according to the direction of the force, meanwhile, the position of the first board B512 also performs the same sliding and position correction, the butt joint dislocation between the male head and the female head of the connector pair B512 is reduced, and finally the connector pair B512 is normally butted, that is, the first board B512 and the second board B508 corresponding to the connector pair B512 are normally butted.

It is easily conceivable that in this embodiment, the first board a504 and the first board C518 may also be fixed on the floating assembly and slide in the first direction, so as to respectively reduce the requirements for the mating tolerance Δ d _ a of the connector pair a502 and the mating tolerance Δ d _ C of the connector pair C516, and ensure that the connector pair a502 and the connector pair C516 can correct the position and reduce the mating misalignment when they are misaligned, and finally mate normally. In a complex subrack, any number and any combination may be selected to determine which first boards need to be mounted on the floating assembly.

In another possible embodiment, the second board may also be mounted on the floating assembly and the second board slides in the second direction, thereby reducing the connector's requirement for interfitting tolerances in the second direction. In one possible implementation, the second direction and the first direction are in a perpendicular relationship. Of course, the first direction and the second direction in this application may be any other possible direction relationship with any angle. As shown in fig. 7, fig. 7 includes: a first single board a 704, a second single board a 706, a connector pair a 702, a first single board B712, a second single board B708, a connector pair B710, a first single board C718, a second single board C714, a connector pair C716, a first floating component 713, a second floating component 715, and a handle bar 720. Compared with the embodiment shown in fig. 5, in the embodiment shown in fig. 7, the second floating assembly 715 is added, and the second board B708 is fixed on the second floating assembly 715, so that floating in the second direction can be performed, and the requirement of the connector for the mating tolerance in the second direction is reduced, thereby ensuring normal docking between the first board B712 and the second board B708.

In the embodiment shown in fig. 5, the first board may be a horizontal service board, and the second board may be a vertical backplane. Of course, it is easily conceivable that the first board and the second board may represent other boards that need to be connected by the connector.

In a possible embodiment, a plurality of the above mentioned computer devices may form a machine frame, and the floating assembly is provided, so as to effectively reduce the requirement for the butt-joint matching tolerance between the single boards in the machine frame, and correct the butt-joint dislocation between the single boards.
