The following describes embodiments of the present invention in detail with reference to the accompanying drawings. The features of the following examples and embodiments may be combined with each other without conflict.

Fig. 2 is a plan view of a plate assembly according to an embodiment of the present invention. As shown in fig. 2, the board assembly 20 includes a plurality of first cards 22 arranged in a first direction (height direction Y in the drawing), and first and second daughter cards 24, 26 arranged to intersect the first cards 22. In this embodiment, there may be a plurality of first and second daughter cards 24, 26, which may be arranged in the direction Z perpendicular to the paper.

the plate assembly 20 may be of an orthogonal architecture. That is, the first card 22 is disposed perpendicular to the first and second daughter cards 24, 26. The three directions X, Y, Z in FIG. 2 are perpendicular to each other, where X corresponds to the horizontal direction, Y corresponds to the height direction, and Z corresponds to the vertical plane of the paper. In the present embodiment, the first and second daughter cards 24, 26 are disposed in a plane defined by the direction X and the direction Y, and thus may also be referred to as "vertical cards," which may operate as "switch cards" in an electronic device (e.g., a switch); the first card 22 is disposed in a plane defined by the directions X and Z, and thus may also be referred to as a "cross card," which may operate as a "service card" in an electronic device (e.g., a switch). In other embodiments, the first card 22 and the first and second daughter cards 24, 26 may be disposed non-vertically across from each other. In other embodiments, the first and second daughter cards 24, 26 are not limited to cards of the same nature. For example, the second daughter card 26 may have a function of a partial "master card" in addition to a function of a "switch card".

The third connector 221 is provided at the mating end (right end in the drawing) of the first card 22, and the fourth connector 251 is provided at the mating end (left end in the drawing) of the first and second daughter cards 24 and 26. By plugging the third connector 221 to the fourth connector 251, the electrical connection and data interconnection between the first board 22 and the first and second daughter cards 24, 26 can be realized.

In other embodiments, the first card 22 may not mate directly with the first daughter card 24 (or the second daughter card 26). For example, a midplane may be disposed between the first card 22 and the first and second daughter cards 24, 26, and the third connector 221 and the fourth connector 251 may be plugged onto opposite surfaces of the midplane, respectively, to enable electrical connection and data interconnection between the first card 22 and the first daughter card 24 (or the second daughter card 26).

to expand the number of pluggable first cards while ensuring the strength of the first and second daughter cards 24, 26, the first daughter card 24 (or the second daughter card 26) may be split into two or more daughter cards in the direction in which the plurality of first cards are arranged.

a first connector 243 is provided on the first daughter card 24 and a second connector 263 is provided on the second daughter card 26. The second connector 263 is movably disposed on the second daughter card 26 and is capable of being plugged with the first connector 243. The mating of the second connector 263 with the first connector 243 enables electrical connection and data interconnection between the first daughter card 24 and the second daughter card 26.

The entirety of the first daughter card 24 and the second daughter card 26 of the data interconnect may be functionally equivalent to a unitary card. Moreover, the split-type first daughter card 24 and the split-type second daughter card 26 are significantly smaller than the integrated-type daughter card in terms of processing difficulty. Furthermore, the strength of the split first daughter card 24 and the split second daughter card 26 is obviously better than that of the integrated board card.

During assembly, the first daughter card 24 and the second daughter card 26 may be plugged into the chassis of the electronic device. Then, the second connector 263 on the second daughter card 26 is moved to be plugged into the first connector 243 on the first daughter card 24, so as to realize data interconnection between the first daughter card 24 and the second daughter card 26. Then, the first board 22 is plugged into the first and second daughter cards 24, 26 through the third connector 221 and the fourth connector 251. A plurality of slide rails 21 extending in the transverse direction X may also be provided on the chassis, and the slide rails 21 may be used to accurately position the first board card 22 in the chassis and ensure accurate insertion of the first board card 22 with the first and second daughter cards 24 and 26.

Of course, other sequences of installation are possible. For example, the first daughter card 24 and the first card 22 are plugged into the chassis, and then the second daughter card 26 is mounted. Then, the second connector 263 on the second daughter card 26 is moved to be plugged into the first connector 243 on the first daughter card 24, so as to realize data interconnection between the first daughter card 24 and the second daughter card 26.

There are various mechanisms for driving the second connector 263 on the second daughter card 26 to move and be inserted into the first connector 243 on the first daughter card 24 after the first and second daughter cards 24, 26 are mounted to the chassis.

Fig. 3 to 5 are schematic structural views of a board assembly according to an embodiment of the present invention, which mainly uses a slider structure to drive the second connector 263 on the second daughter card 26 to move and be inserted into the first connector 243 on the first daughter card 24.

referring to fig. 3-5, and optionally in conjunction with fig. 2, the second daughter card 26 includes a body 260 and a support 262 movable relative to the body 260. The main body 260 is a main functional module of the second daughter card 26, and the support plate 262 is used for fixing the second connector 263. The second connector 263 can be connected to the main body 260 through a wire with an adjustable length, so that the second connector 263 can be used as a port for the main body 260 to transmit data during and after the movement. The primary purpose of the carrier 262 is to enable the second connector 263 to be movably disposed on the second daughter card 26.

Wherein, the second daughter card 26 may be provided with:

The limiting parts 31 and 32 are used for limiting the movement of the supporting plate 262 and the second connector 263 thereon relative to the main body 260 along the first direction Y;

an operation section 36 operable by a user and movable in a second direction (horizontal direction X in the figure) different from the first direction Y;

And conversion portions 33, 34 for converting the movement of the operation portion 36 in the second direction X into the movement of the blade 262 in the first direction Y.

In the embodiment shown in fig. 3 to 5, the position-limiting portions 31 and 32 include a slide rail 32 disposed on the supporting plate 262 and extending along the first direction Y, and a position-limiting post 31 disposed on the main body 260. The limiting column 31 is nested in the slide way 32 and can slide along the slide way 32. The limiting column 31 may be a screw or a bolt with an enlarged head.

In other embodiments, the position-limiting part may also be other position-limiting structures, such as a matching structure of a pulley and a sliding rail, etc., as long as it can fix the stroke of the supporting plate 262 and the second connector 263 thereon, thereby ensuring that the second connector 263 is accurately plugged into the first connector 243 on the first daughter card 24.

The operating portion 36 may be a push rod 36, and the length direction of the push rod 36 is the same as the second direction X. The push rod 36 is nested in a mounting hole 356 and is constrained by the mounting hole 356 to move in the second direction X. In this embodiment, the mounting hole 356 may be provided on one sidewall 35 of the chassis. The outer end of the push rod 36 is operated by a user, and the inner end of the push rod 36 is fixedly connected with a slide block 33.

The transformation parts 33, 34 may include the slide block 33 and the slide groove 34 opened on the support plate 262. The sliding groove 34 extends along a third direction, which is different from the first direction Y and the second direction X. The slider 33 is slidable in said slide slot 34. In this embodiment, an included angle between the third direction and the first direction Y may be the same as an included angle between the third direction and the second direction X.

During assembly, the push rod 36 can be pushed laterally to the left. The slider 33 then moves laterally to the left. The movement of the slider 33 in the second direction X pushes the slide groove 34 and the support plate 262 engaged therewith to move upward. The second connector 263 on the carrier 262 is then mated with the first connector 243 on the first daughter card 24.

further, a stopper 362 may be provided on the push rod 36 to limit the stroke of the push rod 36 in the second direction X, thereby preventing excessive movement of the push rod 36 in the second direction X.

Fig. 6 to 8 are schematic structural views of a board assembly according to another embodiment of the present invention, which mainly uses a link mechanism to drive the second connector 263 on the second daughter card 26 to move and be inserted into the first connector 243 on the first daughter card 24.

Wherein the link mechanism includes a first lever 41 rotatably (rotation shaft R1) mounted on the main body 260, a second lever 43 rotatably (rotation shaft R2) mounted on the main body 260, and a third lever 45 rotatably (rotation shaft R3) mounted on the support plate 262.

The first lever 41 may be composed of three sections 412, 414, 416. The second bar 43 may be composed of two sections 432, 434. The first end (the end at which the segment 412 is located) of the first lever 41 serves as an operating portion for user operation, the second end (the end at which the segment 416 is located) of the first lever 41 is hinged to the first end (the end at which the segment 432 is located) of the second lever 43 by a hinge J1, and the second end (the end at which the segment 434 is located) of the second lever 43 is hinged to the third lever 45 by a hinge J2.

The section 432 of the second rod 43 is provided with a sliding slot 433, and the hinge J1 is sleeved in the sliding slot 433, so that the hinge J1 can slide along the length direction of the section 432.

when assembled, the first lever 41 is rotated in a counterclockwise direction, thereby pushing the second lever 43 to rotate in a clockwise direction about the rotation axis R2. The rotation of the second lever 43 in the clockwise direction further translates into rotation of the third lever 45 in the counterclockwise direction about the rotation axis R3 and upward movement of the support plate 262 with the second connector 263 such that the second connector 263 is plugged into the first connector 243 on the first daughter card 24.

the process of the disassembly operation is reversed from that described above. And will not be described in detail herein.

It is to be noted that there are many other types of linkage mechanisms that can be used to achieve motion conversion, most of which can be applied to the present invention either directly or with simple adaptation.

Fig. 9 to 11 are schematic structural views of a board assembly according to another embodiment of the present invention, which mainly uses a rack and pinion structure to drive the second connector 263 on the second daughter card 26 to move and be inserted into the first connector 243 on the first daughter card 24.

The conversion part for realizing the motion conversion comprises a gear 52, a rack 54 and a connecting rod 51 which are meshed with each other. The gear 52 is rotatably mounted (with the rotational axis R5) on the body 260. A first end Q of the link 51 is rotatably provided on the gear 52, and a second end P of the link 51 is rotatably provided on the support plate 262. The rack 54 is provided with an operating portion 56 projecting outward.

When assembled, the operating portion 56 is pushed upward, and the gear 52 is rotated counterclockwise about the rotation shaft R5. Rotation of the gear 52 in the counterclockwise direction may further translate into rotation of the link 51 and upward movement of the blade 262 along with the second connector 263 such that the second connector 263 is docked with the first connector 243 on the first daughter card 24.

In other embodiments, the vertically disposed rack 54 of the above-described embodiments may be replaced with a horizontally disposed rack. Furthermore, a second gear may be used in place of the rack 54. The second connector 263 can be plugged into the first connector 243 by rotating the second gear.

in each of the above embodiments, the second connector 263 disposed below is driven to move upward to be inserted into the first connector 243. In other embodiments, the first connector 243 disposed above may be disposed to be movable relative to the first daughter card 24. Further, the two connectors can be plugged by driving the first connector 243 to move downward.

In each of the above embodiments, the second connector 263 is disposed on the support plate 262. The operation portion drives the supporting plate 262 to move to realize the insertion of the second connector 263 and the first connector 243. In other embodiments, the supporting plate 262 may not be provided, and the operation portion may be directly used to drive the second connector 263 to implement the movement of the second connector 263 and the insertion with the first connector 243. Furthermore, the direction of movement of the operating portion and the second connector 263 may be the same, so that there is no need to provide a converting portion as described above.

The embodiment of the invention also provides electronic equipment, such as a switch. The electronic device may comprise a board assembly as described in any of the previous embodiments.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
