[Problems to be Solved by the Invention] By the way,
In a conventional connector having a slider for connecting a cable to a magnetic disk device or the like, as shown in FIG.
A relatively large force is required to slide the slider 11 to the open position in order to remove the cable 8 from the state of being fixed. If too much force is applied at that time, the slider 1
1 is disengaged from the socket 20, and the strength of the slider guide 15 is generally not sufficient in many cases, so that the slider guide 15 is broken.

The present invention has been made in view of such a conventional problem, and when the slider is slid to the open position in order to disconnect the cable, the slider is disengaged from the socket even if an excessive force is applied to the slider. Or
An object of the present invention is to provide a destruction prevention mechanism for a connector in which a slider guide is not destroyed.

[0005]

As a means for solving the above-mentioned problems, the present invention has a structure in which a connector having a slider for connecting a cable to a magnetic disk device is connected. The gist of the present invention is to provide a stopper that projects from the chassis side of the magnetic disk device and limits the stroke of the connection opening operation of the slider of the connector.

[0006]

With the above construction, when the cable is connected to and released from the magnetic disk device, the stroke of the connection opening operation of the slider of the connector is limited by the stopper. Therefore, the slider is slid to the open position in order to disconnect the cable. However, the slider will not come off the socket and the slider guide will not be broken even if a little excessive force is applied.
