Assistance plug-unplug handle assembly for printed board connecting mechanism

Abstract

The invention discloses an assistance plug-unplug handle assembly for a printed board connecting mechanism. The assistance plug-unplug handle assembly comprises an assembly body (1), a plug-unplug positioning mechanism (11) and a handle (12), wherein one end part of the plug-unplug positioning mechanism (11) is connected with one end part of the assembly body (1), the handle (12) is connected with the other end part of the assembly body (1), the plug-unplug positioning mechanism (11) comprises two positioning projected parts (111) connected with a plug element tray (3), the ranging direction of the two positioning projected parts (111) is vertical to the direction of the handle (12), and positioning grooves (112) matched with a machine frame are arranged on the positioning projected parts (11). The front panel space of the plug element tray can be sufficiently utilized, the intensity of the front panel of the plug element front panel is enhanced, the equipment assembly density is improved, and the assistance plug-unplug handle assembly has the advantages that the connection is firm and reliable, the plug-unplug reliability is high, and the use is simple and convenient.

Description

technical field [0001] The invention relates to the field of high-performance computing equipment and communication equipment, in particular to a power-assisted plugging handle assembly for fast plugging and plugging of a printed board connection mechanism with a large number of IO connectors on the front panel. Background technique [0002] At present, most high-performance computing equipment and communication equipment adopt a backplane assembly structure. This structure can cancel the signal and power interconnection lines at the back end of the plug-in board. The wiring distance between printed boards can greatly improve the reliability of signal and power lines. With the rapid increase in speed and size of computing equipment and communication equipment, the number of interconnection signals between the plug-in printed board and the backplane is also increasing exponentially. [0003] At present, the number of interconnection pins between the plug-in printed board and...

Problems solved by technology

However, there will be the following problems like this: when the plug-in tray 3 is inserted, since the plate-shaped power-assisted plug-in handle 2 is located on the top of the plug-in tray 3, it is biased with the backplane socket on the plug-in printed board 4, and is applied to the plate-shaped The force on the power-assisted plug-in handle 2 is converted into a bending moment acting on the front panel of the plug-in tray 3, so no matter how much force is applied, it will only cause the front panel 32 of the plug-in tray 3 to bend, and the plug-in printed board 4 cannot be placed The socket is combined with the backplane socket; the positioning protrusion 24 can only realize the up and down positioning of the plate-shaped power-assisted plugging handle 2, but cannot realize the positioning of the inserting and pulling out state of the plug-in tray 3, and the plug-in of the plug-in tray 3 is easily not in place. The backplane socket on the plug-in printed board is easy to loose, and the problem of automatic pop-up of the plug-in tray 3 is prone to occur; the opening of the first positioning groove 23 is rectangular, so that the operation of the plate-shaped power-assisted plug-in handle 2 is not smooth, and it is difficult to open and close. strenuous

In addition, in order to prevent blocking the IO connector 41, the design length of the plate-shaped power-assisted plug-in handle 2 is often limited, and the plug-in force of the plug-in printed board socket 4 is very large, so a plate-shaped power-assisted plug with a short arm is used. It is very laborious to pull out the handle 2 to realize the plug-in operation of the plug-in tray 3
