A plug-in auxiliary plug-in puller used in conjunction with a chassis

Abstract

The invention discloses a plug-in plug-in / extractor used in conjunction with a chassis, comprising a traveling beam, a lifting beam, a pull rod, a wrench, a roller, a first straight pin and a second straight pin, and the roller is riveted by the first straight pin At one end of the wrench, the handle is in contact with the running beam through the roller; the running beam is provided with a round hole, one end of the pull rod is fixed on the lifting beam, and the other end passes through the round hole on the running beam and is hinged to the wrench through the second cylindrical pin. The two ends of the lifting beam are attached to the inner sides of the two ends of the traveling beam and can slide along the inner sides of the two ends. The two ends of the traveling beam are provided with convex and concave claws embedded in the slots of the chassis. Plug and unplug the block to match the notch. The plate moves the wrench, the roller rolls on the surface of the running beam, and the pull rod drives the lifting beam and the plug-in to move to complete the insertion and removal of the plug-in. The invention applies force to the case and the plug-in in the same direction as the direction of insertion and extraction, has low requirements on the strength and weight of the case, does not easily cause damage to the case, and balances force on the upper and lower plug-in blocks of the plug-in.

Description

technical field [0001] The invention belongs to the box plug-in technology, in particular to a plug-in plug-in and pull-out aid used in conjunction with the box. Background technique [0002] At present, most of the plug-in plug-in aids are installed on the plug-in panel, and the upper and lower symmetrically form a pair, which is an integral part of the plug-in. With the continuous development and innovation of new technologies, especially the VPX and other electrical connectors with large plug-in force In use, higher requirements are placed on the strength of the chassis and plug-in aids. During the insertion and removal process of the existing plug-in aids, due to the symmetry of the upper and lower sides, a pair of forces are applied to the chassis. The force at a large angle is applied to the chassis. If the plug-in electrical connector has a large insertion force, the chassis cannot reach a certain weight and strength, and there are defects such as easy damage, deform...

AI Technical Summary

Problems solved by technology

During the insertion and removal process of the existing plug-in aids, due to the symmetry of the upper and lower sides, a pair of forces are applied to the chassis. The force at a large angle is applied to the chassis. If the plug-in electrical connector has a large insertion and withdrawal force, the chassis will not reach a certain weight and strength, and there will be defects such as easy damage, deformation, and affecting use at the contact with the plug-in aid.

And due to the large number of plug-ins in a set of equipment, the number of plug-in and pull-out devices has doubled, and the number of plug-ins has reached tens or hundreds. A pair of plug-in and pull-out devices must be installed on each plug-in, which not only increases the weight, but also increases the Cost, especially in aerospace and aviation equipment, the defects of large weight are more obvious and unacceptable
