Description

[Detailed Description of the Invention] This invention relates to a portable radio device such as a transceiver.

This type of portable radio has a push-button switch for transmitting calls called a press-to-talk switch. A push button switch is provided on the side wall of the housing. In such cases, a switch cover that covers the mounting part of the transmitter push button switch is attached to the housing as part of waterproofing measures. A leaf spring is attached to improve the operability of the push button switch. However, in the conventional structure, both ends of the leaf spring are fixed to the opening edge of the switch cover, and only the so-called central belly part is held so that it can be elastically bent. If the vicinity of the button is pressed, there is a risk that the pressing force will not be transmitted to the push button switch, causing a communication error.

This invention was made for the purpose of solving the above-mentioned conventional drawbacks, and embodiments thereof will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, this portable radio device includes a housing 1 consisting of a rectangular frame that can be held with one hand, and a transmitting/receiving circuit, a speaker, etc. (not shown) are installed inside the housing 1. It is becoming built-in. In this figure, the housing 1 is shown with the front panel and back cover removed. Referring also to FIG. 2, one side wall 2 of the housing 1
is equipped with a push-button switch 3 called a press-to-talk switch for transmitting calls.
A switch cover 4 for protecting the push button switch 3 from rainwater, etc. is screwed onto the side wall 2 via a waterproof gasket 5. The switch cover 4 has a rectangular opening 6, and a switch is disposed within the opening 6 at a predetermined distance from the push button switch 3, and selectively acts on the push button switch 3. A leaf spring 7 is attached. In this case, both ends of the leaf spring 7 are fixed by, for example, welding the heads of boss members 8, 8 that are protruded from the back side of the switch cover 4, but the central portion that occupies most of the ends is fixed. The tongue piece 10 is cantilevered by a slit 9 cut into a substantially U-shape except for one side. Further, a rubber waterproof cover 11 formed to cover the entire leaf spring 7 is attached to the opening 6 of the switch cover 4 in a watertight manner. In addition, since the leaf spring 7 is made of a thin plate of metal or synthetic resin,
The tongue piece 10 formed cantilevered by the slit 9 exhibits soft elasticity over almost its entire surface. Furthermore, in the above embodiment, the slit 9 is cut into a substantially U-shape, but as shown in FIG. It may also be modified to form the tongue piece 10 by cutting it out.

According to the above-mentioned structure, since the tongue piece 10 formed by the slit 9 is provided in the central part of the leaf spring 7, simply touching the tongue piece 10 lightly turns on the transmitting push button switch 3. It can be turned off. In that case, since the tongue piece 10 is much softer than a conventional leaf spring, the push button switch 3 can be reliably switched no matter which part of the tongue piece is pressed, and there is almost no possibility of causing a communication error. do not have. In particular, as in this embodiment, it is planned that a socket (not shown) for connecting external devices such as an external power source, an antenna, and a microphone will be installed as an option, and a flexible printed wiring board 12 for connecting to the socket will be installed. It is more effective if the push button switch 3 is designed to be pulled out from inside the housing 1 through the upper part of the push button switch 3 in advance. In other words, if the flexible printed wiring board 12 is pulled out in this way, its repulsion (restoring force) will interfere with the on/off operation of the push button switch 3, but in this invention, As described above, since the tongue piece 10 exhibiting extremely flexible elasticity is provided, for example, even if the proximal end side of the tongue piece 10 is pressed, the pressing force is not hindered by the flexible printed wiring board 12 and the push button switch can be pressed. 3 can be reliably informed.
