Embodiment Construction

[0054] A plug-in disk with a puller of the present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings.

[0055] The overall structure of the plug-in disk with the puller of the present invention is as follows: figure 1 As shown, the inserting disc is made up of a puller 20, an inserting disc panel 30, a printed circuit board 50, a connecting shaft 10, a countersunk screw 40 and a wear-resistant washer 60. The connecting shaft 10 passes through the puller 20, the printed circuit board 50, the wear-resistant washer 60 and the insert panel 30 in turn, and the countersunk screw 40 penetrates from the insert panel 30 and the corresponding installation hole and is screwed inside the connecting shaft 10. . The cooperation between the puller 20 and the connecting shaft 10 is clearance fit, and the puller 20 can rotate freely. The wear-resistant washer 60 is installed between the extraction aid 20 and the printed circuit boar...

Abstract

The invention discloses an inserting disk with a pull assisting device. The inserting disk with the pull assisting device comprises the pull assisting device (20), an inserting-disk face plate (30), a printed circuit board (50) and a connecting shaft (10), wherein the connecting shaft (10) is in a stepped shape, and a mounting hole (501) of the printed circuit board (50) is in a special-shaped hole structure which is capable of preventing rotation of the connecting shaft (10). The pull assisting device (20) comprises a head portion (201) and a handle (203), a stepped shape is formed between the head portion (201) and the handle (203), and a boss (202) is arranged at the transition position of the handle (203) and the head portion (201). A notch (303) is arranged at one end of the junction position of a bottom plate portion (302) and a face plate portion (301) of the inserting-disk face plate (30), and the handle (203) of the pull assisting device (20) penetrates through the notch (303) and is located outside the inserting-disk face plate (30). By means of the inserting disk with the pull assisting device, the pull assisting device, the printed circuit board and the inserting-disk face plate can be well assembled with high reliability, and cost is low.

Description

technical field [0001] The invention relates to a plug-in disk with a puller used in the field of optical communication, and the invention belongs to the field of communication. Background technique [0002] With the continuous development of communication technology and the continuous improvement of service integration, the number of service plugs placed in the same volume of equipment space increases accordingly, and the space occupied by a single service plug decreases. It is convenient for the service plug-in disk to be inserted and removed within the effective space. [0003] Assembling a puller on the service plug-in disk, on the one hand, can play a role in facilitating plugging and unplugging; To achieve good results, the following issues need to be addressed: [0004] The assembly method of the extraction aid, the plug-in panel and the printed circuit board is required to be reasonable, the number of assembly parts is as small as possible, the processing cost of t...
