Veneer guide sleeve and veneer device with same

Abstract

The invention discloses a veneer guide sleeve and a veneer device with the same. The veneer guide sleeve comprises a body, a positioning hole for inserting a guide pin is formed in the middle of the body, an inclined step is arranged on the peripheral side of one end of the positioning hole, a protruding structure is arranged on the inner wall of the positioning hole in the radial direction in anextending mode, and the protruding structure comprises two inclined faces which are connected. According to the veneer guide sleeve disclosed in the technical solution, while the misplug prevention function is achieved, the adaptation capacity of the single board is enhanced, the flexibility and usability of system configuration are improved, the configuration capacity of the system is improved, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of single boards of network communication equipment, in particular to a single board guide sleeve and a single board device with the guide sleeve. Background technique [0002] In a case of an electronic device, especially a case of a communication device, a single board is inter-plugged with a corresponding external connector on a backplane to realize inter-board communication. [0003] In the prior art, the anti-mis-insertion of single boards in the chassis is generally realized by designing guide sleeves 6 and guide pins 7 on the single board and the back board respectively, such as figure 1 As shown, the anti-mis-insertion position of the cross section of the guide sleeve 6 is a one-to-one structure, the guide sleeve 6 and the guide pin 7 are matched in a one-to-one manner, and the configuration of the slot and the board is also in a one-to-one relationship. This way, the system configuration capability ...

AI Technical Summary

Problems solved by technology

For example, if there are 8 board slots on the backplane, and a guide pin with a fixed direction is set on each slot, and there are two switching boards, one monitoring board, and one power board, then there are only 4 slots left. Reserved for the business board, if it is necessary to increase the business board to improve the configuration of the system, it will be limited

If different veneers use the same guide sleeve 6 and guide pin 7 to cooperate, it will not be able to effectively prevent mis-insertion; and if the same veneer is realized by replacing the guide sleeve 6 on site, it will bring difficulties in engineering maintenance. High cost, easy to insert the wrong slot
