Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a waveguide structure used in wireless communication equipment that allows two sets of waveguide circuits to be easily attached and detached.

As one of the waveguide attachment/detachment mechanisms, the present inventors proposed
-176406 was proposed in Figure 1.

This structure is in a solid line state during normal use.

Further, when electrical measurement is performed on the flexible waveguide 1, etc., it is tilted forward as shown by the imaginary line.

In this tilting structure, an L-shaped bracket 3 is fixed to a flexible waveguide 1, and this L-shaped bracket 3 is fixed to a bracket 4 projecting in a U-shape using four screws 2.

Note that the support 5 that supports the waveguide 1 is a rod.

This structure requires removing four screws 2 each time the waveguide is attached or detached.
It required installation work and was not easy to put on and take off.

Furthermore, in a state in which electrical measurements of the waveguide are not performed, that is, in a state in which the flexible waveguide 1 is not tilted forward, the screws 2 are not fixed, so there is a drawback that the screws tend to come off.

An object of the present invention is to solve these drawbacks and provide a waveguide attachment/detachment mechanism that facilitates attachment and detachment.

The present invention will be explained in detail below with reference to the drawings.

The basic configuration of the present invention uses the configuration shown in Fig. 1, but instead of the conventional screw fastening, a guide pin is provided and this guide pin is inserted into the pin hole, which constitutes the present invention. The configurations of the L-shaped bracket and the U-shaped bracket are slightly different.

FIGS. 2a and 2l) are a partially sectional side view and a front view of the L-shaped bracket 3 used in the present invention.

This L-shaped bracket 3 has a hole 1 on the bottom of this bracket.
5 is opened and one end of a guide pin 11 is made to protrude, and this guide pin 11 is held by a metal fitting 13 fixed to the inside of the bottom surface of the bracket 3 through a coil spring 12.

A lever 14 is fixed to the other end of the guide pin 11 through a hole 16 larger than the hole 15.

The lever 14 has a chamfered end so that it can easily slide over the folded portion 20 of the bracket 3, as shown in the detailed view of FIG.

Note that by pushing this lever 14, the guide pin 1
1 can be retracted into the bottom surface of the bracket 3.

Furthermore, slide pins 17 and 18 with thick tips are fixed to the bottom surface of the bracket 3.

On the other hand, the U-shaped bracket 4 for fixing is provided with gourd holes 30 and 31 and a round hole 32 for a guide pin, as shown in the perspective view of FIG.

The holes 30 and 31 are opened corresponding to the positions of the slide pins 17 and 18, respectively, when the flexible waveguide 1 is inclined as shown in the imaginary line in FIG. The inclination angle of the curtain is the same as the inclination direction of the flexible waveguide 1.

The guide pin round hole 32 is opened at the position where the guide pin 11 fits when the slide pins 17 and 18 are inserted into the gourd holes 30 and 31, respectively, and fitted into the small diameter part of the gourd. It is.

The operation of this waveguide attachment/detachment structure is as follows.

First, the flexible waveguide 1 is tilted as shown in the imaginary line (
1), insert the slide pins 17 and 18 into the gourd holes 30 and 31 of the bracket 4, respectively, slide the bracket 3 in the direction of the arrow in FIG. and the small diameter portion of 31.

The guide pin 11 hits the surface of the bracket 4, compresses the coiled spring 12, slides in the direction of the arrow in FIG. 4, and when it reaches the guide pin hole 32, the guide pin 11 is pressed by the coiled spring 12 and inserted.

In this state, the slide pins 17 and 18 are fitted and fixed into the small diameter portions of the gourd holes 30 and 31, so the L-shaped bracket 3 fixed to the waveguide is firmly fixed to the U-shaped bracket 4. Ru.

That is, the waveguide is fixed to the bracket 4 in the state shown by the imaginary line in FIG.

On the other hand, when removing this waveguide, guide pin 1 in Fig.
Since the round hole 16 is larger than the round hole 15 for 1, the lever 14 moves in the direction of the arrow Y in FIG.
It can be rotated in the direction of arrow X around .

Since the lever 14 has a chamfer 21, the bracket folded part 20
Even if the chamfer 23 hits the bracket folded part 20, it can be overcome.

Therefore, the guide pin 11 comes off from the guide pin hole 32 of the bracket 4, and by sliding it in the opposite direction in the direction of the arrow in FIG. 4, the slide pins 17 and 18 can be easily removed from the gourd holes 30 and 31. can.

As explained above, according to the present invention, the waveguide can be attached and detached with a single touch, and there is no possibility of the waveguide being lost due to unscrewing.
