When the base 103 and the pulling part 101 are die castings, the base can bear large acting force without deformation and fracture, so that the use requirement of a large insertion and extraction force system is met.

As another aspect of the present invention, a communication device is provided, which may be a switch. Communication equipment includes subrack and veneer, and fig. 10 is the schematic diagram when the utility model discloses the embodiment in the time of the veneer inserts the subrack, combines to show fig. 4 and fig. 10, and the subrack includes: the single board 30 is supported on the bottom plate 43 and is used for plugging and unplugging on the back plate 41. In addition, the communication device further comprises the plugging auxiliary mechanism 10 provided in the above embodiment, and one end of the rotating shaft 102 of the plugging auxiliary mechanism 10 is fixed on the side wall 42 of the plug-in box. The single plate 30 is provided with a fixed block 20, and the engaging opening 101c of the pulling member 101 is used for engaging with at least a part of the fixed block 20.

As described above, the fixing block 20 may be in a shape of a "convex", and a portion of the fixing block 20 engages with the engagement opening 101c during the insertion and removal of the veneer.

In practical application, the plugging auxiliary mechanisms 10 may be disposed on both sides of the inserting box along the width direction, and the pulling members 101 on both sides apply force simultaneously, so that a large plugging force can be resolved into a small force in a balanced manner, and the single board 30 is stably moved toward or away from the back plate 41.

In one embodiment, as shown in fig. 4, 5 and 10, the single plate 30 is provided with a slide 31, and the slide 31 extends along the inserting and pulling direction of the single plate 30. The bottom plate 43 is provided with a limit pin 32, the limit pin 32 is used for moving relative to the single plate 30 along the slide way 31, and the guide can be performed in the plugging and unplugging process of the single plate 30 through the matching of the limit pin 32 and the slide way 31. The length of the slideway 31 is slightly larger than the plugging stroke of the single board, so that the single board 30 can overtravel, and the single board 30 can be fully inserted into the connector.

Further, as shown in fig. 5 and 10, the slide 31 may be a through hole penetrating through the single plate 30, and may be in the form of a gourd hole, specifically, the slide 31 includes a first through portion 31a and a second through portion 31b communicating with the first through portion 31a, the first through portion 31a is located on a side of the second through portion 31b close to the box back plate 41, both the first through portion 31a and the second through portion 31b penetrate through the single plate, and a width of the first through portion 31a is greater than a width of the second through portion 31 b. Here, the width is a dimension in a direction perpendicular to the extending direction of the slide 31. The stopper pin 32 specifically includes: the slide portion 32c and the first stopper portion 32a disposed at the tip of the slide portion 32c, the bottom end of the slide portion 32c is fixed to the bottom plate 43, the first stopper portion 32a can pass through the first through-hole 31a, the dimension of the first stopper portion 32a in the width direction of the slide 31 is larger than the width of the second through-hole 31b, and the dimension of the slide portion 32c in the width direction of the slide 31 is smaller than or equal to the width of the second through-hole 31 b.

In this case, the limit pin 32 may further include a second limit portion 32b, and the bottom end of the sliding portion 32c is fixed on the bottom plate 43 through the second limit portion 32 b. The dimension of the second stopper portion 32b in the width direction of the slide 31 is larger than the width of the second through portion 31 b. Wherein, the height of the sliding portion 32c is equal to or slightly greater than the thickness of the single plate 30.

The first through portion 31a may be cylindrical, the first stopper portion 32a and the second stopper portion 32b may be disc-shaped, and the diameter of the first stopper portion 32a is smaller than that of the first through portion 31a, so that the first stopper portion 32a may pass through the first through portion 31 a; the size of the sliding portion 32c in the width direction of the slide 31 may be slightly smaller than or equal to the width of the second through portion 31b, so that the sliding portion 32c can slide along the second through portion 31b and prevent the veneer 30 from shaking in the width direction of the slide 31.

As shown in fig. 4 to 10, when the veneer 30 is inserted, the limiting pin 32 may first pass through the first through portion 31a of the sliding way 31, and when the veneer 30 is pushed toward the back plate 41, a rotational force is applied to the force applying portion 101a of the pulling member 101, and the side wall of the engagement opening 101c pushes the fixing block 20 to move toward the back plate 41, so as to drive the veneer 30 to move toward the back plate 41 until the pulling member 101 abuts against the top end of the first limiting plate 104b of the cover plate 104, and at this time, the veneer 30 is completely matched with the connector on the back plate 41 and some of the veneer 30 passes through the stroke. Because the direction of the acting force applied on the pulling part 101 is perpendicular to the moving direction of the single plate 30, when the acting forces on the pulling parts 101 on the left side and the right side are different, the single plate 30 is warped and twisted in the moving process, so that the problems that the connector on the back plate 41 is bent and cannot be matched occur; in the embodiment of the present invention, the dimension of the first position-limiting portion 32a in the width direction of the slide 31 is greater than the width of the second through portion 31b, so that the single plate 30 can be prevented from moving upward, and the dimension of the second position-limiting portion 32b in the width direction of the slide is greater than the width of the second through portion 31b, so that the single plate 30 can be prevented from bending downward, thereby preventing the single plate 30 from warping and twisting.

When the single board 30 is separated from the connector on the back board 41, at the initial separation time, the stopper pin 32 is located at one end of the slide 31 away from the back board 41, and the urging portion 101a of the pulling member 101 abuts against the top end of the first stopper plate 104b of the cover plate 104. At this time, the force applied to the force applying portion 101a is opposite to the force applied during insertion, so that the side wall of the occlusion port 101c pushes the fixing block 20 to move away from the back plate 41, thereby moving the single plate away from the back plate 41 until the separation from the connector on the back plate 41 is completed.

In the embodiment of the present invention, the moving stroke of the veneer can be limited by the cooperation of the limit pin 32 and the slide 31, and therefore, the setting of the limit cover plate 104 can be cancelled under the condition of setting the limit pin 32 and the slide 31.

It is right above the embodiment of the utility model provides a plug complementary unit and communication equipment's description can be seen, plug complementary unit's the piece that draws adopts vertical mode that sets up, compares with the horizontal mode that sets up among the prior art, and shared scope reduces in the veneer region when drawing the piece activity to need not the device on the veneer to do too much and dodge, and draw when the piece activity can not be because of sheltering from of device lead to the activity limited, and then improve the plug effect of veneer. Moreover, the plug auxiliary mechanism is simple in overall structure and easy to realize. In addition, in the communication equipment comprising the plugging auxiliary mechanism, the single board can be prevented from warping in the plugging process through the matching of the limiting pin on the back plate and the slideway on the single board.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
