FIG. 1 is a schematic view of a single board insert into a receptacle in place and with a drawer; FIG. 2 is a schematic view of a single plate one-piece insert/extract and extractor; FIG. 3 is a schematic diagram of a connection between a single board and a puller; as shown in fig. 1-3, a multi-layer guide rail is provided on a plug-in box 1 of a communication device, a whole veneer 2 includes a panel and a veneer (the veneer is specifically a printed circuit board PCB), a puller 3 is assembled on the panel, the veneer is assembled on the panel, the pulling piece pulling the puller 3 moves the whole veneer, and then the plugging between the veneer and the backboard is assisted, the plugging between the veneer and the backboard is that: and inserting and separating the orthogonal connector of the single board and the back board. Usually, when a single board is inserted into the subrack 1, the pulling part of the puller needs to rotate counterclockwise, and the clamping interface on the puller and the side wall of the subrack 1 are locked, so that the single board is inserted into the subrack 1; when the single board is pulled out of the plug box 1, the pulling part of the pulling device needs to rotate clockwise, and the clamping interface on the pulling device is separated from the side wall of the plug box so as to complete the pulling out of the plug box 1 by the single board. The inventor finds that when a single board is inserted into the jack 1, the pulling element of the puller 3 is opposite to the panel, and the panel is usually provided with a communication port such as an optical fiber interface, so that the pulling element blocks the communication port, thereby affecting the plugging and unplugging of signal wires such as optical fibers.

In view of the foregoing problems, the following technical solutions are provided in the embodiments of the present disclosure.

In a first aspect, fig. 4 is a schematic diagram of a single board integral unit inserted into a subrack in place and a puller in an embodiment of the present disclosure, as shown in fig. 4, an embodiment of the present disclosure provides a puller, where an auxiliary single board 21 is integrally inserted into a back plate of the subrack 1, and the single board 21 includes a single board 21 and a panel 12; the inserting box 1 comprises an inserting frame 11, and a fixing block 22 is arranged on the inserting frame 11; the extractor of this disclosed embodiment includes: a first rotating shaft 32, a second rotating shaft 33, a driving piece 34, a driven piece 35 and a pulling piece 31; wherein, the first rotating shaft 32 and the second rotating shaft 33 are both connected with the single plate 21; a driving member 34 rotatably connected to the first shaft 32; the driven piece 35 is rotatably connected with the second rotating shaft 33, and the driven piece 35 is provided with a clamping interface; the pulling piece 31 is connected with the driving piece 34, and the pulling piece 31 is used for controlling the driving piece 34 to drive the driven piece 35 to rotate along a plane where the pulling piece 31 and the veneer 21 intersect under the action of external force; when the single board 21 is inserted into the inserting box 1 in place, the clamping interface is clamped on the fixing block 22 of the inserting box 1, and the extending direction of the pulling part 31 is perpendicular to the plane of the panel 12.

It should be noted that, a side of the fixing block 22 on the inserting box 1 facing the back plate is defined as a first side, and a side opposite to the first side is defined as a second side; the side wall near the first side surface when the opening interface is locked with the fixing block 22 is defined as a first side wall, and the side wall near the second side surface is defined as a second side wall.

In the embodiment of the present disclosure, the driven element 35 in the extractor is driven by the driving element 34 under the control of the pulling element 31, and after the single board 21 is inserted into the subrack 1 in place, the first side wall of the card interface of the driven element 35 abuts against the first side surface of the fixed block 22, that is, the card interface of the driven element 35 is locked with the fixed block 22 on the subrack 1, and in this state, the extending direction of the pulling element 31 of the extractor is perpendicular to the plane of the panel 12, it can be seen that the pulling element 31 does not shield the communication port on the panel 12, so that the plugging and unplugging of signal lines such as optical fibers are not affected.

In some embodiments, fig. 5 is a schematic view of a single board one-piece pullout subrack and pullout in embodiments of the present disclosure; as shown in fig. 5, when the single board 21 is pulled out of the inserting box 1, the extension direction of the pulling piece 31 is opposite to the plane of the panel 12 under the action of external force. For example: when the single plate 21 needs to be pulled out of the plug box 1, the pulling member 31 rotates 90 degrees counterclockwise from the insertion state under the action of external force, meanwhile, the driven member 35 rotates 90 degrees clockwise, the second side wall of the clamping interface abuts against the second side surface of the fixing block 22, the clamping interface is separated from the fixing block 22, and therefore the single plate 21 can be pulled out of the plug box 1.

In one example, when the single board 21 is pulled out of the insert box 1, the extension direction of the pulling piece 31 is parallel to the plane of the panel 12 under the action of external force. Thus, even if a plurality of single plates 21 are simultaneously inserted into the box 1 and the single plates 21 are close to each other, when one single plate 21 is pulled out, the single plate 21 close to the single plate 21 is not affected and the space occupied by the panel 22 is saved. Of course, it should be understood that, when the single board 21 is pulled out of the box 1, the relationship between the extending direction of the pulling member 31 and the plane of the panel 12 depends on how many angles the pulling member 31 rotates can make the second side wall of the card interface abut against the second side surface of the fixed block 22, so in the embodiment of the present disclosure, only when the single board 21 needs to be pulled out of the box 1, the projection of the pulling member 31 on the plane of the panel 12 falls on the panel 12.

In some embodiments, the driving member 34 and the driven member 35 may each include, but are not limited to, a gear structure. When the driving member 34 and the driven member 35 adopt a gear structure, the driving member 34 has a first engaging portion, and the driven member 35 has not only a snap interface but also a second engaging portion; when the pulling member 31 controls the driving member 34 to drive the driven member 35 to rotate, the first engaging portion is engaged with the second engaging portion.

It should be noted that, the first engaging portion and the second engaging portion are both structures including protrusions and grooves which are alternately arranged; when the driving member 34 drives the driven member 35 to rotate, the protrusion of the first engaging portion falls into the groove of the second engaging portion, and simultaneously the protrusion of the second engaging portion falls into the groove of the first engaging portion.

In some embodiments, the first shaft is non-detachably connected to the driving member 34, and the first shaft and the driving member can be connected by any one of the methods including, but not limited to, clinching, expanding riveting, spin riveting, and screwing.

In some embodiments, the second shaft is non-detachably connected to the driven member 35, and the second shaft and the driven member can be connected by any one of the methods including, but not limited to, riveting, expanding riveting, spin riveting, and screwing.

In some embodiments, the extractor further comprises a fixing seat 36, the fixing seat 36 being connected to the single plate 21, the first rotating shaft 32 and the second rotating shaft 33 being fixed to said fixing. The fixing seat 36 is connected to the single plate 21 in a manner including, but not limited to, screwing. In one example, a through hole (or a nut 37) may be provided on the fixing seat 36, and the fixing seat 36 is connected with the single plate 21 through a connecting member.

In some embodiments, the driving member 34 and the pulling member 31 are a unitary structure, i.e. the driving member 34 and the pulling member 31 constitute a wrench. Thus, the driving member 34 and the pulling member 31 can be formed in one process. Of course, the driving member 34 and the pulling member 31 may be separate structures as long as they are fixedly connected.

In one example, the side wall of the plug-in frame 11 of the plug-in box 1 is provided with a fixing block 22, and a back plate is also arranged in the plug-in box 1; the single plate whole piece comprises a panel 12, a single plate 21 and a connector; the pulling device comprises a fixed seat 36, a driving part 34, a driven part 35, a first rotating shaft 32, a second rotating shaft 33 and a pulling part 31; the fixing seat 36 is fixed on the single plate 21 by a screw, the driving member 34 is fixed on the fixing seat 36 by the first rotating shaft 32, the driven member 35 is fixed on the fixing seat 36 by the second rotating shaft 33, and the driving member 34 and the first rotating shaft 32, and the driven member 35 and the second rotating shaft 33 are connected in a non-detachable manner. The driving piece 34 is provided with a first engaging part, the driven piece 35 is provided with a clamping interface and a second engaging part, and the clamping interface is matched with the fixing block 22 on the side wall of the inserting frame 11; the second engaging portion is engaged with the first engaging portion, and when the pulling member 31 controls the driving member 34 to rotate around the first rotating shaft 32, the driving member 34 is driven by the driven member 35 to rotate around the second rotating shaft 33, it can be understood that the rotating directions of the first rotating shaft 32 and the second rotating shaft 33 are opposite.

As shown in fig. 4, the single plate 21 is inserted into the insertion frame 11 in a position where the pulling member 31 is perpendicular to the panel 12; when the veneer 21 is to be pulled out, the pulling member 31 is rotated 90 ° counterclockwise, the driving member 34 is also rotated 90 ° counterclockwise, as shown in fig. 5, and at this time, the driven member 35 is rotated 90 ° clockwise, and the driven member 35 abuts against the second side surface of the fixing block 22 of the inserting frame 11, so that the veneer 21 is moved outward and pulled out. FIG. 6 is a transition schematic diagram of a single plate full insert subrack in an embodiment of the present disclosure; when the veneer 21 is to be inserted, the pulling member 31 is rotated clockwise as shown in fig. 6, the driving member 34 is also rotated clockwise, the driven member 35 is driven to rotate counterclockwise, the driven member 35 contacts with the first side surface of the fixing block 22 to press the veneer 21 inward, so that the veneer 21 is inserted into the insertion frame 11, and finally, the veneer 21 is inserted into position as shown in fig. 1.

In a second aspect, the present disclosure provides a communication device, which may be a switch, and includes an insert box 1 and a single board 21, where the above-mentioned extractor is connected to the single board 21. When the single board 21 is inserted into the plug-in box 1, the connector on the single board 21 is connected with the connector on the back board of the plug-in box 1.

Because the driven member 35 in the extractor of the embodiment of the present disclosure is driven by the driving member 34 under the control of the pulling member 31, and after the single board 21 is inserted into the subrack 1 in place, the first side wall of the card interface of the driven member 35 abuts against the first side surface of the fixed block 22, that is, the card interface of the driven member 35 is locked with the fixed block 22 on the subrack 1, and in this state, the extending direction of the pulling member 31 of the extractor is perpendicular to the plane of the panel 12, it can be seen that the pulling member 31 does not shield the communication port on the panel 12, so the plugging and unplugging problem of the signal lines such as optical fibers cannot occur.

The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, and are not to be construed as limiting the scope of the invention. Any modifications, equivalents and improvements which may occur to those skilled in the art without departing from the scope and spirit of the present invention are intended to be within the scope of the claims.
