DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high frequency connector mounting structure for mounting a high frequency connector to a structure such as a chassis.

[0002]

2. Description of the Related Art In general, a cable connection between devices is performed through a connector. In particular, a high-frequency cable is connected through a coaxial connector.

A conventional high frequency connector mounting structure will be described with reference to FIGS.

In the figure, reference numeral 1 denotes a male connector, 2 denotes a female connector, and the male connector 1 is adapted to be fitted to the female connector 2. For example, a unit device 3 in which the male connector 1 is mounted on a chassis or the like. And the female connector 2 is mounted on a structure such as the chassis 4.

In general, the unit equipment 3 is mounted via a guide, and a plurality of connectors are connected when the unit equipment 3 is mounted. Therefore, it is unavoidable that a displacement occurs between the male connector 1 and the female connector 2 due to a component error, an assembly error, and the like. For this reason, one of the male connector 1 and the female connector 2 has a floating structure for eliminating positional deviation.

In the conventional example shown in FIGS. 7 and 8, the male connector 1 has a floating structure.

The male connector 1 is adapted to be mounted on the unit equipment 3 via a connector mounting bracket 5. A hole for a cable to be described later and a screw hole for mounting the connector are formed in the connector mounting bracket 5. The male connector 1 has a rectangular flange portion 1 a, and the flange portion 1 a is It is fixed to the mounting bracket 5.

The connector mounting member 5 is further provided with a hole 7 for mounting a chassis.
The floating collar 8 is loosely fitted in the. The floating collar 8 is a flanged collar, and the male connector 1 and the female connector 2 described above are provided between the fitting portion 8a of the floating collar 8 and the chassis mounting hole 7.
There is sufficient play to eliminate the positional deviation between them, and the height of the fitting portion 8a is slightly larger than the thickness of the connector mounting bracket 5.

A screw hole 11 for fixing the connector mounting bracket 5 is formed in the chassis 3a of the unit device 3, and a corner relief hole 12 which does not interfere with the screw 6 when the male connector 1 is mounted. Are drilled.

To mount the connector mounting bracket 5 on the chassis 3a, the floating collar 8 is fitted into the chassis mounting hole 7, the bolt 9 is inserted into the floating collar 8, and the screw hole 11 is inserted. Screw. The connector mounting bracket 5 is supported in a state of being sandwiched between the flange portion 8b of the floating collar 8 and the chassis 3a, and moves freely by the play between the fitting portion 8a and the chassis mounting hole 7. It is getting.

The tip of the male connector 1 is tapered so that automatic alignment can be performed within the range of the taper.

[0012]

In the above-described conventional high frequency connector mounting structure, the connector mounting bracket 5 is mounted via the floating collar 8. There is play between the floating collar 8 and it is difficult to maintain the male connector 1 in the specified position with the male connector 1 attached to the unit device 3 due to the play between the floating collar 8 and the chassis mounting hole 7. If the positional deviation due to play exceeds the self-alignment range of the taper of the male connector 1, the male connector 1 and the female connector 2 may not be fitted when the unit device 3 is mounted. Therefore, the workability is not good, for example, fine adjustment is required at the time of assembly.

Further, when one unit device 3 has a plurality of high-frequency connectors, each high-frequency connector is individually attached, and since there is no function of holding each high-frequency connector on the floating side at a reference position, there is a play. However, the alignment between the connectors has been more troublesome.

Further, since each high-frequency connector is individually mounted, a connector mounting bracket 5, a floating collar 8, and the like are required, which increases the number of parts and requires a mounting space. For this reason, cost reduction,
There was a problem that miniaturization of the device was hindered.

The present invention has been made in view of the above circumstances, and aims to reduce the number of parts, improve assembling workability, reduce costs, and promote downsizing of an apparatus.

In this embodiment, the male connector 1 is fixed, and the female connector 2 has a floating structure.

The male connector 1 has a flange portion 1a directly fixed to the unit equipment 3 by screws (not shown).

The female connector 2 has a fitting portion 15 into which the male connector 1 is fitted, a neck portion 16 having a small diameter, and a flange portion 17 having a large diameter. The fitting portion 15 penetrates through the chassis 4, and a play hole 21 having a smaller diameter than the flange portion 17 is formed. The play hole 21 is sandwiched between the play hole 21 and a screw hole 22 (see FIG. 2 places).

The female connector 2 is inserted into the play hole 21 from the side opposite to the unit device 3 of the chassis 4, and the elastic holding piece 18 is fitted to the flange portion 17 in a press-fit state. The elastic holding piece 18 has a high elasticity, has an elastic deformation amount equal to or larger than a displacement between the male connector 1 and the female connector 2 and is slightly thicker than the thickness of the flange portion 17. A female connector holding hole 19 having the same shape as the portion 17 is formed, and a fixing hole 20 corresponding to the screw hole 22 is formed with the female connector holding hole 19 interposed therebetween. The female connector holding hole 19 has the flange 17
Is press-fitted so that there is no backlash in the fitted state.

The box fitting 23 is further fitted to the elastic holding piece 18 in a press-fit state. An escape hole 24 through which the end of the female connector 2 penetrates is formed in the box fitting 23, and a fixing hole 26 corresponding to the screw hole 22 is formed so as to sandwich the escape hole 24.

The box fitting 23 is formed with a wiring cutout 25 reaching the escape hole 24 in consideration of wiring work. Further, the size of the escape hole 24 has a margin that the end of the female connector 2 can be sufficiently displaced.

The procedure for mounting the female connector 2 will be described.

First, the flange portion 17 is fitted into the elastic holding piece 18, the elastic holding piece 18 and the female connector 2 are integrated, and the fitting portion 15 is inserted through the play hole 21. Next, a cable (not shown) connected to the female connector 2 is connected to the escape hole 2 through the notch 25 for wiring.
