BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device package housed in an electronic device housing.

[0002]

2. Description of the Related Art In recent years, an electronic device package housed in an electronic device housing has a high mounting density due to speeding up of signals, miniaturization of components, etc., and a connector for connecting the electronic device housing and the electronic device package. Is required more and more with smaller number of pins.

However, the contact portion of the connector is also downsized, and the number of pins per unit area is increasing. However, the strength of the insulating material used for the body of the connector and the strength of the metal used for the contact are different from the conventional ones. It is the same.

[0004]

However, in the conventional electronic equipment package mounted with such a high density multi-pin connector, the fitting condition is very severe. Therefore, there is a problem in that, when the connector is inserted or removed by a normal operation, the connector body is damaged, or the contact part is bent or the like.

An object of the present invention is to solve the above-mentioned problems, and to provide an electronic device package capable of surely eliminating problems such as connector body damage and pin bending of a contact portion due to forcible insertion and removal. To provide.

[0006]

The invention according to claim 1 is
A printed circuit board having a connector that can be fitted to a connector on the electronic equipment housing side, an ejector that is rotatably supported by the printed circuit board and that can be inserted into and removed from the electronic equipment housing, and a front side of the ejector. The configuration is such that it is provided with an elastic body that restricts rotation of the ejector.

According to a second aspect of the invention, the elastic body is fixed to the printed circuit board with screws.

According to a third aspect of the invention, the ejector is provided with a groove at its tip end so as to straddle the printed circuit board.

[0009]

As described above, according to the present invention, the ejector is in the upright state when the force of the elastic body is not applied to the ejector, so that the printed circuit board can be inserted into or removed from the electronic equipment casing. , The ejector must be applied with force, and the ejector must be inserted by tilting the ejector. Therefore, when inserting or removing the printed circuit board, it is necessary to always use the ejector to engage and disengage the printed circuit board. Can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing an embodiment of an electronic device package according to the present invention, FIG. 2 is a perspective view of an ejector mounted on the electronic device package, and FIG. 3 is an elastic body mounted on the electronic device package. 4 and 5 are operation explanatory views of the electronic device package. The electronic device package is arranged and fixed to the printed circuit board 1 and one end side of the printed circuit board 1, and is intended for connection with the electronic device housing.
A high-density multi-pin connector 2 and an ejector 4 which is rotatably disposed near a lower portion of the other end of the printed circuit board 1 via a rotary shaft 3 and which is inserted into and removed from an electronic device housing. And a screw 5 on the other end of the printed circuit board 1.
And an elastic body 6 fixed via the.

As shown in FIG. 2, the ejector 4 is provided with a groove 7 in the tip portion 4A so as to straddle the printed circuit board 1, and the elastic body 6 is substantially on the crank as shown in detail in FIG. The vertical portion 6A is formed so as to face the front surface side of the tip portion 4A of the ejector 4.

Next, the operation will be described with reference to FIGS. Generally, the ejector 4 of the electronic device package is shown in FIG.
It is inserted into the electronic device casing 8 in the state as shown in FIG. At this time, the ejector 4 exerts a force in the arrow A direction (see FIG. 5) due to the elasticity of the elastic body 6. Therefore, when a force is applied to the ejector 4 through the finger 9 in the direction of the arrow B, the state shown in FIG. 5 is obtained, and the tip projection portion 4B of the ejector 4 passes through the guide rising portion 8A of the electronic device housing 8. You can As a result, the multi-pin connector 2 can be fitted into the connector (not shown) mounted on the back wiring board of the electronic device casing 8.

[0014]

As described above, according to the electronic device package of the present invention, the elastic body for restricting the rotation of the ejector is provided on the front side of the ejector. When no force is applied to the ejector, the ejector is in the upright state, and in order to insert or remove the printed circuit board into or from the electronic device housing, force must be applied to the ejector and the ejector must be inserted or removed in the state of being tilted. No longer.

Therefore, when the printed circuit board is inserted or withdrawn, the ejector is always used to engage or disengage the connector. Therefore, the connector body is damaged due to the excessive insertion or withdrawal as in the conventional case, and the contact is removed. This has an excellent effect that it is possible to surely prevent a defect such as a pin bending of the portion.
