Injector/ejector system for a plug-in module and apparatus using the systems

Claim 1

A injector/ejector system for a plug-in module comprising a circuit board in which electrical components are mounted on at least one rectangular surface of the circuit board and are surrounded by the four sides, a grip for inserting and removing the module which is mounted on a first side of the circuit board, second and third sides of the circuit board adjacent to the first side and running parallel to each other which are intended to slide, a first connector for electrical connection mounted on any one side of the circuit board other than the first side, and a housing comprising a guide means for guiding the second and third sides of the circuit board of the plug-in module when the fourth side of the circuit board is inserted into the housing such that the plug-in module may slide into the housing up to a predefined position and a second connector that may be electrically connected with the first connector when the plug-in module is inserted to the predefined position; the grip of the plug-in module having a first end portion and a second end portion, the first end portion having a first engaging end that may be deformed by pressure and which generates a resilient force, the grip being attached to the plug-in module by means of a rotating shaft at a predefined position between the first and second end portions so that the grip may be rotated in a plane parallel to the surface of the circuit board; the resilient force of the first engaging end of the first end portion exerting pressure so as to allow engagement between the first engaging end and a second engaging end provided in the housing when the plug-in module is inserted into the housing up to the predefined position, while deformation of the first engaging end allowing disengagement between the first end portion and the second engaging end in the housing when pressure is applied against the resilient force of the first end portion; the second end portion having a protruding portion which is in a position separated from the insertion side of the housing when the first and second engaging ends are engaged, which lies to one side of the second end portion, which abuts the insertion end of the housing when the first and second engaging ends are disengaged and the first end portion is pulled away from the first side of the circuit board, causing the grip to rotate on its shaft, and which applies a force that assists in removing the plug-in module from the housing as the first end portion is further rotated.
