Description

Self ejector device for communication equipment {EJECTOR FOR SHELF IN COMMUNICATION SYSTEM}

The present invention relates to a shelf for communication equipment (e.g., an electronic exchange system, etc.), and is particularly provided on a front panel of a unit mounted on the shelf to instruct detachment of a printed circuit board. It relates to an ejector device (ejector).

Typically, a box-shaped communication device shelf is mounted with a plurality of units. In order to mount the unit on the self, guide supports are installed at equal intervals in the vertical direction, and guide rails are installed at the same angles at right angles to the guide supports. It is assembled with screws to allow sliding movement. The unit is assembled with a front panel to the front, and an ejector is installed on the upper and lower parts of the front panel to instruct the removal of the printed circuit board according to the user's hand movements. In addition, the front panel is provided with a gasket according to the model to prevent the transmission of electromagnetic waves generated from the printed circuit board. The rear side of the printed circuit board is provided with a mail connector pin, and is connected to the female connector of the motherboard installed on the back plate of the self when the system is structured to operate.

As shown in Figures 1 and 2, the unit mounted on the communication equipment self as described above, the ejector 19 is installed on the front panel of the unit bar, the ejector 19 is large body 12 and It is composed of a base 11, the structure is separated when the injection (injecting), is separated when the injection (ejecting), the structure using the rocker 13 for vertical self-reliance of the printed circuit board after injection to be. The rocker 13 is assembled to the base 11, and the lever 14 is assembled to the rocker 13 so that the user pulls or pushes the lever 14, i.e., prints at the time of injection or ejection. The circuit board 10 was attached and detached. The ejector 19 and the printed circuit board 10 are fixed by using a rivet 17 prepared separately.

In the operation of detaching the printed circuit board 10 by the ejector 19, the point A is a center point of force when the ejector 19 releases the locked state of the printed circuit board 10 (injecting). Point B is a portion at which the ejector 19 locks the printed circuit board 10 (when ejecting), where the center point of force acts. Therefore, when the printed circuit board 10 is to be attached and detached from the ejector 19, the structure is possible by simple hand operation. The angle of rotation of the ejector 19 is a right angle, and is a structure for supporting the load concentrated around the working point of the force. In this way, the printed circuit board can be easily attached and detached according to the operation of the ejector installed on the front panel.

However, the conventional communication equipment equipped with the ejector device is light and short, high density, high speed is being developed, the number of pins of the connectors installed on the printed circuit board and the motherboard is rapidly increased, the unit is pushed into the self-mounting In doing so, a problem occurred in the connection force between the two connectors. In other words, the connection force is weak, the connection force is reduced even in a weak shock or vibration, and if continued, a serious problem of connection failure occurred.

Moreover, after inserting the unit into the shelf, the structure is inefficient to transmit the force for mounting the printed circuit board using a separate rocker. That is, when the ejector operates, a method of assembling the ejector by forming a hole in the printed circuit board is stressed when the force is moved, thereby causing a problem in which the crack is occasionally generated in the printed circuit board.

The present invention has been made to solve the above-described problems, the object of the present invention is to provide an ejector device of the self-communication device for communication equipment that can transmit more force by increasing the contact area of the ejector structure with the guide support. It is.

Another object of the present invention is to provide a shelf for communication equipment that, when mounted on the shelf of the unit, accurately strengthens the connecting force of both connectors.

In order to achieve the above objects, the present invention is a self ejector device for communication equipment,
