Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a press talk switch used for switching a switch of an operation unit in a portable radio device.

[Prior Art] FIG. 3 is an exploded perspective view of a conventional press talk switch.

Reference numeral 1 denotes a housing, which has a recess 1a and a hole 1b on one surface thereof, and the hole 1b
The switch 5 was protruding from.

Reference numeral 6 is a lever, and rib-shaped projections 6a on both side surfaces of the lever 6 are retained on the inner surface of the frame body 7 to hold the lever 6. Then, the frame body 7 is fixed from the inside of the housing 1 with the screw 8.

In the conventional press talk switch having such a configuration, since the head of the switch 5 contacts the inner surface of the lever 6, the switch 5 is turned on by pressing the lever 6.
/ OFF was possible.

[Problems to be solved] In the above-mentioned conventional press talk switch, since the lever, the frame, and the like are fixed from the inside of the housing, it is difficult for a tool to enter during assembly, or when the parts are replaced, they are mounted inside the housing. There was also a problem that parts could not be replaced unless the printed circuit board and wiring were removed.

The present invention has been made in view of the above-mentioned problems. A press which enables easy assembly by fixing the frame body from the outside of the housing and allows replacement of parts only by removing screws from the outside. The purpose is to provide a talk switch.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a portable wireless device including a housing, a frame body fitted in a recess of the housing, and a lever locked to the frame body. The housing has a switch, and the frame body has a long hole for engaging and supporting one end portion of the lever at an upper end portion inside thereof, and the frame body in the housing at a proper position inside. Each of the holes has a screw hole for fixing and a switch projecting hole through which the switch penetrates, and the lever is rotatable, and the casing is provided through the hole of the frame body. While covering the head of the screw screwed to the body,
The frame is engaged with the switch protruding from the switch protruding hole.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the present invention, and FIG. 2 is a side sectional view showing a locked state of a lever and a frame.

In the drawings, reference numeral 1 is a housing of a portable wireless device. The housing 1 has a recess 1a formed on its side surface, and a hole 1b is provided at an appropriate position of this recess.

Reference numeral 2 is a frame body of the press talk switch fitted in the housing 1, and 3 is a lever locked to the frame body 2 by the shaft 4.

An elongated hole 2a having a size into which the upper end of the lever 3 can be inserted is provided at the upper end of the frame body 2. Further, on both inner surfaces of both sides of the elongated hole 2a, locking grooves for supporting both ends of the shaft 4 are provided.
An opening 4 a is provided inside the frame body 2.

Furthermore, at the lower end of the frame body 2, the claw portion 3b of the lever 3 is provided.
A locking portion 2c for locking the is provided.

Reference numeral 2b denotes a switch projecting hole, which allows the switch 5 to project from the inside of the housing 1 when the frame 2 is fitted into the housing 1.
It is provided corresponding to 1b.

A hole 3a for inserting the shaft 4 is provided in the lateral direction of the upper end of the lever 3.

Next, a procedure for assembling the press talk switch having such a configuration will be described.

First, the long hole 2a provided at the upper end of the lever 3 on the upper portion of the frame 2
To the inside of the housing 1. Then, in this state, the shaft 4 is inserted into the hole 3a of the lever 3.

Next, both ends of the shaft 4 are locked to the locking grooves 4a provided on both inner surfaces of the long hole 2a.

As a result, as shown in FIG. 2, the lever 3 is engaged with the elongated hole 2a and rotatably supported by the shaft 4. After that, the structure body including the frame body 2, the lever 3, and the shaft 4 is fitted into the recess 1 a of the housing 1. Then, the lever 3 locked to the frame body 2 is lifted, and the screw 8 is screwed into the screw hole 2d from the outside of the frame body and fixed.

Next, the lever 3 is bent to fit the claw portion 3b into the locking portion 2c, and the lever 3 is locked to the frame body 2.

The head of the switch 5 projects through the holes 1b and 2b and is in contact with the lever 3. Therefore, when the front surface of the lever 3 is pushed, the switch 5 inside is pushed, and the ON / OFF operation of the switch becomes possible.

Further, the lever 3 can be removed from the frame body 2 by inserting a pin into a hole 2e provided on the side surface of the frame body 2 and prying it.

[Effects of the Invention] As described above, according to the present invention, the frame of the lever of the press talk switch is screwed and fixed from the outside of the housing to facilitate the assembly, and after assembly, the head of the screw is assembled. Since it is covered with a cover, it has the effect of improving the appearance.
