Description

[Detailed Description of the Invention] This invention relates to a module fixing device for electronic equipment.

Fig. 1 is a front view showing an example of a conventional module fixing device, and Fig. 2 is a sectional view showing an example of a conventional module fixing device. In the figure, 1 is a module, 2 is a chassis base, and 3 is a set screw. , 4 is an insertion guide pin, 5 is a connector, and 6 is a spacer structure.

Conventionally, the module has been fixed by directly fixing the module 1 to the chassis base 2 with screws.

Further, as shown in FIG. 1, a plug-in module is provided with an insertion guide pin 4 and a connector 5 is mated thereto, and the fixing device of a plug-in module that is frequently removed is provided with a mechanism to prevent screws from falling off.

The spacer structure 6 shown in FIG. In order to prevent the screw from falling out, the set screw 3 was designed to prevent it from falling out.

As mentioned above, in conventional module fixing devices, a spacer structure with a tap at the tip that prevents the setscrew from falling off is fixed to the chassis base. It was difficult to dimensionally align the female threaded holes, and it was often impossible to insert the male threaded portion of the set screw into the female threads of the module.

Additionally, if the module is forcefully inserted and fixed, the screws often seize or break easily.

This idea was made to eliminate the drawbacks of the conventional ones as mentioned above, and instead of fixing the spacer structure to the chassis base, which serves to prevent the set screw from falling off,
To provide a module fixing device which allows a module to be easily attached and detached even if there is a dimensional error in the installation position of a screw by supporting it with a channel plate so that it can move within a certain range in each direction along the surface of a chassis base. The purpose is to

FIG. 3 is a cross-sectional view showing one embodiment of this invention. In the figure, 1, 2.3 indicate the same or corresponding parts as the same reference numerals in FIG. 1 and FIG. A spacer structure sandwiched between the knob part and chassis base 2.
A tap corresponding to the external thread of the set screw 3 is cut at the tip.

A channel plate 8 is fixed to the chassis base 2 and supports the spacer structure 7 so as to be movable within a certain range in each direction along the surface of the chassis base 2.

The male threaded portion of the set screw 3 is inserted into the female thread provided in the module 1 by passing through a tapped hole provided at the tip of the spacer structure 7, as in the conventional module fixing device shown in FIG. Ru.

Therefore, even if the male threaded portion is pulled out from within the female thread provided in the module 1, it will not come out of the tapped hole provided in the spacer structure 7, so the set screw 3 will not fall out.

Since the spacer structure 7 is supported by the channel plate 8 and can be moved according to the minimum distance between the spacer structure 7 and the channel plate 8, the set screw 3 can also be moved accordingly, and is mounted on the module 1. Even if there is some deviation in the position of the female thread provided, the male threaded portion can be inserted into the female thread provided in the module 1 by adjusting the position of the set screw 3.

As described above, according to this invention, the spacer structure that serves to prevent the set screw from falling off can be moved within a certain range in each direction along the surface of the chassis base, so that the female screw of the module can be positioned with some error. Even if installed, the module can be easily fixed, the screws will not seize or break easily, exact dimensional accuracy is not required,
It has the advantage of being inexpensive and easy to manufacture.

[Brief explanation of the drawing]

FIG. 1 is a front view showing an example of a conventional module fixing device, FIG. 2 is a sectional view showing an example of a conventional module fixing device, and FIG. 3 is a sectional view showing an embodiment of this invention. In the figure, 1 is a module, 2 is a chassis base, 3 is a set screw, 7 is a spacer structure, and 8 is a channel plate. Note that the same reference numerals in each figure indicate the same or corresponding parts.
