Description

  The present invention relates to an electronic device in which a printed circuit board is connected perpendicularly to a backboard, an ejector that prevents damage to a connector mounted on the printed circuit board when the printed circuit board is pulled out, an eject structure provided with the ejector, and an electronic device About.

  As shown in FIG. 4, the card 21 (printed circuit board) in which the cable connector 23 is inserted perpendicularly to the insertion / extraction direction, when removing the card 21 from the card support gauge 24, before pulling out the card 21 from the backboard 27, The cable connector 23 guided by the connector guide 25 must be removed.

  This is because if the card 21 is pulled without removing the cable connector 23, the connector 26 may be damaged, and the card 21 may become unusable.

  However, it is sometimes forgotten that the cable connector is actually removed.

  For this reason, it is required to prevent the connector from being damaged even if the cable connector is forgotten to be removed.

As a technique related to preventing damage to a connector due to forgetting to remove a cable connector, there is an “optical fiber protection mechanism” disclosed in Patent Document 1.
The invention disclosed in Patent Document 1 has a structure in which the package is not pulled out from the shelf unless the optical cable is removed.
Japanese Utility Model Publication No. 1-118489

  However, in the structure of the invention disclosed in Patent Document 1, the connector and the ejector must be close to each other. Further, the connector can be provided only in the vicinity of the peripheral edge of the package. That is, there is a restriction on the connector installation position on the card, which is not preferable in realizing optimal mounting of electronic components on the card.

  As described above, the ejector that prevents the connector from being damaged due to forgetting to remove the cable connector, the eject structure including the ejector, and the electronic device have not been realized without any restriction on the position of the connector on the printed circuit board.

  The present invention has been made in view of such problems, and an ejector that prevents damage to a connector due to forgetting to remove a cable connector without any restriction on the position of the connector on the printed circuit board, and an eject structure provided with the ejector An object is to provide an electronic device.

  In order to achieve the above object, as a first aspect, the present invention supports a printed circuit board in order to remove the printed circuit board having a first connector that is inserted and removed perpendicularly to a socket on the backboard. Direction in which the first connector is deformed when the operation is performed in a state in which the connector cable is connected to the second connector installed on the printed circuit board, and the first connector is removed from the socket. It is an object of the present invention to provide an ejector characterized in that the above force is not applied to a printed circuit board.

  In order to achieve the above object, according to the present invention, as a second aspect, the ejector according to the first aspect of the present invention is installed in a frame for supporting a printed circuit board. It provides an eject structure.

  In order to achieve the above object, the present invention provides, as a third aspect, an electronic apparatus comprising the eject structure according to the second aspect of the present invention and a backboard. is there.

  According to the present invention, it is possible to provide an ejector that prevents damage to the connector due to forgetting to remove the cable connector, an eject structure including the ejector, and an electronic device without restricting the position of the connector on the printed circuit board.

  FIG. 1 shows a configuration of an electronic apparatus according to a preferred embodiment of the present invention. As shown in the figure, in this electronic apparatus, the insertion / extraction direction of the card 1 and the insertion / extraction direction of the cable connector 3 are perpendicular to each other. Forgetting to remove the cable connector 3 guided by the connector guide 5 from the connector 2, the card 1. If the card 2 is taken out from the card support cage 4, the connector 2 is damaged.

  FIG. 2 shows the structure of an ejector provided in the electronic apparatus according to the present embodiment. In the ejector 8, the operation unit 11 and the action unit 12 are disposed so as to be rotatable about the support point 10 as a pivot. In addition, the ejector 8 is provided with a spring 9, and normally, the operation portion 11 and the action portion 12 are urged so as to have a substantially L shape.

  As shown in FIG. 3, by applying a force exceeding the urging force of the spring 9, the ejector 8 bends around the support point 10 as a pivot and exhibits a substantially V shape. When the force applied to the ejector 8 is released, the ejector 8 again assumes a substantially L shape due to the biasing force of the spring 9.

  The ejector 8 is fixed to the card support cage 4 so as to be rotatable about a shaft 13 provided at the action portion 12.

  The biasing force of the spring 9 is stronger than the resistance force when the connector 6 is inserted into and removed from the backboard 7 when the connector cable 3 is not inserted, and the connector 6a is connected to the backboard 7 when the cable connector 3 is inserted. It is set to be weaker than the resistance force when it is pulled out from the upper socket 6b.

The operation during ejection will be described.
When the connector cable 3 is removed from the connector 2, when a force in the circumferential direction of the shaft 13 is applied to the operation portion 11, the ejector 8 rotates with the shaft 13 as a fulcrum, and the tip of the action portion 12 contacts the card 1. Touch. In the state where the connector cable 2 is removed from the connector 2, the resistance force when the connector 6 a is extracted from the socket 6 b is weaker than the biasing force of the spring 9, so that the ejector 8 maintains the substantially L-shaped shaft. 13 is rotated as a fulcrum, and the action portion 12 applies a force in the extraction direction to the card 1 by the lever principle. As a result, the card 1 is removed from the card support cage 4.

  On the other hand, in the state in which the connector cable 3 is inserted into the connector 2, the ejector 8 is bent into a substantially V shape with the support point 10 as a fulcrum because the resistance force when the connector 6a is pulled out from the socket 6b is stronger. 1 is not extracted.

  Thus, even if the electronic device according to the present embodiment tries to pull out the card while forgetting to pull out the cable connector, the card is not pulled out, so that the connector provided on the card is not broken.

In addition, the said embodiment is an example of suitable implementation of this invention, and this invention is not limited to this.
For example, in the above embodiment, a configuration using a torsion spring is taken as an example. However, if the ejector is in an extended state in a normal state and the ejector can be deformed when a force stronger than a predetermined force is applied, this configuration is used. There is no limit.
As described above, the present invention can be variously modified.

It is a figure which shows the structure of the electronic device which concerns on suitable embodiment of this invention. It is a figure which shows the structure of the ejector which concerns on suitable embodiment of this invention. It is a figure which shows the state which the ejector deform | transformed with the external force. It is a figure which shows the structure of the electronic device relevant to this invention.
