Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector housing mounting structure for electronic equipment, and more particularly to a structure for mounting the connector housing to a frame.

[Conventional technology]

Conventionally, a structure shown in FIG. 5 has been used as a plug-in type electronic device for electrically connecting a package housed in a frame by fitting a plug and a connector. That is, the connector housing 4 is attached to the frame 1 having the guide rail 2 via the support metal fitting 3, and the plug 6 provided in the package 5 inserted along the guide rail 2 is provided in the connector housing 4. 7 is fitted to make an electrical connection.

With such a configuration, the amount of displacement of the mutual positional dimensions between the package 5 and the frame 1 is corrected, and the plug 6 and the socket 7 are suitably fitted without applying an unreasonable fitting force. For this purpose, the connector housing 4 is movably supported by the support fitting 3.

For example, FIG. 6 is an example thereof, in which the diameter of the shaft portion 8a of the mounting screw 8 for attaching the connector housing 4 to the support fitting 3 is smaller than the inner diameter of the mounting hole 4a of the connector housing 4 and the plate thickness is small. By making the length longer than that, the connector housing 4 is made possible by defining a gap between the two.

As another example, as shown in FIG. 7, a floating washer 9 movable in the mounting hole 4a of the connector housing 4 is inserted into the mounting hole 4a, and the washer 9 is supported by a screw 10 to support the metal fitting 3 The connector housing 4 is made movable by fixing the connector housing 4 to.

[Problems to be solved by the device]

In any of the conventional mounting structures described above, the connector housing is made movable by providing a gap between the mounting screw 8 or the floating washer 9 and the connector housing 4, so that when the connector housing 4 is mounted along the direction of gravity. The connector housing 4 is always attached in a state of being displaced in the direction of gravity by the gap. Therefore, when the plug 6 and the socket 7 are fitted to each other, the shift amount of the connector housing 4 and the socket 7
Due to the positional tolerance of the
However, there is a problem in that the two cannot be fitted at all.

An object of the present invention is to provide a mounting structure which eliminates the displacement of the connector housing in the direction of gravity and enables a suitable fitting between a plug and a socket.

[Means for Solving the Problems]

The connector housing mounting structure of the present invention is such that the connector housing is supported so as to be movable relative to the frame by a mounting screw formed to have a diameter smaller than that of the mounting hole formed in the frame, and between the mounting screw and the mounting hole. It is characterized in that a drum-shaped spring ring having elastic force in the radial direction of the shaft portion of the mounting screw is inserted in the gap.

According to another mounting structure of the present invention, the connector housing is provided with a frame and has a diameter smaller than that of the mounting hole. The floating washer is installed inside the mounting hole, and the mounting screw is inserted through the floating washer. It is characterized in that a drum-shaped spring ring having an elastic force in the radial direction of the floating washer is interposed in the gap between the floating washer and the mounting hole so as to be movable relative to the floating washer.

[Action]

With this configuration, the connector housing is prevented from moving downward in the direction of gravity due to the elastic force of the spring ring, while the relative displacement of the fitted plug and socket is prevented by the elastic deformation of the spring ring. Absorb by.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of the essential parts of a first embodiment of the present invention.
The same parts as those in the figure are designated by the same reference numerals. In this embodiment, a spring ring 11 is inserted into the mounting hole 4a of the connector housing 4, and the connector housing 4 is supported by the mounting bracket 8 of the frame 1 by the mounting screw 8 via the spring ring 11.

The spring ring 11 is a thin sheet metal having a plurality of slits 11a, as shown in FIG. 2 as a whole perspective view, and in FIGS. 3 (a) and 3 (b) as a partially cutaway front view and side view, respectively. Is formed into a drum shape with an open winding end, and is configured so that elastic force in the radial direction is applied.

The mounting screw 8 has its shaft portion 8a fixed to the mounting hole 4a.
Supporting the connector housing 4 by making the diameter smaller and making it longer than the plate thickness of the mounting hole 4a portion of the connector housing 4 and inserting the central hole of the spring ring 11 and screwing the threaded portion thereof into the support fitting 3. It is supported by the metal fitting 3.

According to this structure, the spring ring 11 is provided in the gap between the shaft portion 8a of the mounting screw 8 and the mounting hole 4a of the connector housing 4.
Will be inserted. Therefore, it is possible to prevent the connector housing 4 from moving downward in the direction of gravity due to the elastic force of the spring ring 11, and it is possible to prevent a large displacement between the plug 6 and the socket 7. On the other hand, the elastic deformation of the spring ring 11 allows the connector housing 4 to be moved relative to the mounting screw 8, that is, the support fitting 3, and absorbs the positional deviation between the plug 6 and the socket 7. It goes without saying that a suitable fit between the two is realized.

FIG. 4 is a sectional view of the essential parts of a second embodiment of the present invention.
The same parts as those in FIGS. 3 to 3 are designated by the same reference numerals.

In this embodiment, the floating washer 9 is inserted into the mounting hole 4a of the connector housing 4 and fixed to the support fitting 3 with the screw 10, and the spring ring 11 is inserted between the floating washer 9 and the mounting hole 4a. ing.
The spring ring 11 is substantially the same as that shown in FIGS. 2 and 3, but has a large inner diameter here.

With this configuration, the elastic force of the spring ring 11 acts in the radial direction on the peripheral surface of the floating washer 9,
The connector housing 4 is elastically supported by the support fitting 3. Also in this embodiment, the spring ring
The elastic force of 11 can prevent downward movement of the connector housing 4 in the direction of gravity, and can absorb the positional deviation between the plug 6 and the socket 7 to realize a suitable fitting.
Same as the embodiment.

[Effect of device]

As described above, according to the present invention, since the drum-shaped spring ring having elastic force in the radial direction is inserted in the gap between the mounting hole of the connector housing and the mounting means for supporting the connector housing, this spring is used. The elastic force of the ring prevents the connector housing from moving downward in the direction of gravity, and allows the connector housing to be supported at a predetermined position. Further, the relative displacement between the plug and the socket to be fitted can be absorbed by the movement of the connector housing due to the elastic deformation of the spring ring, and an unreasonable fitting force between them can be prevented.
