Description

  The present invention relates to a cable connection device, and more particularly to a cable connection device with excellent work efficiency when an optical fiber cable is connected to an electronic device.

  When connecting a cable to an electronic device (hereinafter simply referred to as “device”), a technology is generally used in which an expansion card called a unit card or interface card is inserted, a connector is connected, and the cable is connected to the device via the expansion card. It has been broken.

  Here, the following two techniques are mainly known as techniques for connecting apparatuses with optical fiber cables.

  One is a technology in which a connector for connecting an optical fiber cable is mounted on the front surface of the unit card, and after inserting and mounting the unit card in the shelf, the connector for connecting the optical fiber cable is inserted. This is a so-called front maintenance method. However, if a connector for connecting an optical fiber cable is inserted into the front surface, the optical fiber cable may conceal an LED that displays status information on the front surface of the unit card. Further, since it is necessary to remove the optical fiber cable when exchanging the unit card, the maintenance workability is poor and the appearance is not good.

  The second is a technology in which a connector for connecting an optical fiber cable is mounted on the back side of the unit card, and the connector for connecting an optical fiber cable is inserted into the back panel at the same time as inserting and mounting the unit card into the shelf. Since this is a so-called back surface maintenance method, work on the back surface side occurs, and work efficiency is poor. Further, since the work is performed on the back surface, the work efficiency cannot be said to be good, for example, the work cannot be performed while viewing the LED or the like that displays the status information on the front surface of the unit.

  As a technique for mounting a printed wiring board, for example, in Patent Document 1, a first connector member and a second connector member are connected by a flat cable, and another printed wiring board can be inserted and removed from each. Thus, a technique for improving workability is disclosed.

  As another technique for mounting another circuit board, for example, in Patent Document 2, a link plate is attached to a circuit board such as a PCI card so as to be rotatable, and a lever of the link plate is operated. A technology that enables smooth insertion and removal of a circuit board is disclosed.
