Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a waterproof structure for a wireless communication device used in a place where there is a risk of flooding such as rainwater.

[Outline of device] With respect to waterproofing of wireless communication equipment, it may be included in the standard configuration from the beginning of the product, or it may be installed later, depending on customer requirements. In the latter case, the addition of waterproof specifications
It is not desirable for the appearance design to change and the operability of the operation part to change.

Therefore, it is desired that the parts with waterproof specifications should be processed inside so that they do not appear in the appearance of the product, and that there is almost no difference in operability.

[Conventional technology]

In recent years, as wireless communication devices have become lighter and more compact, portable types have become the mainstream. For this reason, it is essential to have a waterproof function to prevent rainwater. In addition, the number of buttons on the operation unit is increasing due to the multi-functionalization.

Under such circumstances, the conventional waterproof structure of the wireless communication device has a structure as shown in FIGS. 4 and 5. In this case, rubber is used as the waterproof component. Therefore, when operating the button, the operating finger directly touches the rubber. Rubber is flexible, and the feel of the operating finger is not desirable.

Further, the exposure of such rubber on the appearance not only results in stains and is difficult to clean, but also results in damage to the design.

[Problems to be solved by the device]

 The above-mentioned conventional techniques have drawbacks in operability and appearance design.

It is an object of the present invention to improve these drawbacks, provide a waterproof function, make the operation smooth, and provide a waterproof packing that does not damage the design.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention arranges a waterproof packing, which has been exposed to the outside, between a switch and an operation button, and the shape of the waterproof packing is such that it contacts the operation button as shown in FIG. Is provided with a convex shape.

[Action]

The operation of the present invention will be described. Since pressure is applied between the operation panel and the switch retainer, it is possible to prevent rainwater from entering from the outside. Also, when the convex portion of the waterproof packing is pushed by operating the switch and the operating finger is released, the operating button automatically returns to its original position by the repulsive force of the switch and the repulsive force of the convex portion. be able to.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. An operation panel 2 arranged on the front surface of the wireless communication device 1 is provided with a display unit, an operation unit, and a voice input unit for operating all functions of the wireless communication device. Of these, the part that especially requires waterproofing is the part that operates mechanically in the operating part.

In this embodiment, the operation button 3 is held on the operation panel in a movable state through the waterproof packing 4, the switch retainer 5, the switch 6 and the substrate 7. The operation panel 2 is provided with a receiver 8 for receiving the waterproof packing 4.

Further, the operation button 3 has a protrusion 9 at a position opposed to the switch 6. Further, the waterproof packing 4 has a recess 10 into which the protrusion 9 can be inserted, and a conical projection 11 is provided around the recess 10.

Hereinafter, this operation will be described.

The waterproof packing 4 is held in a compressed state by a receiver 8 provided on the operation panel 2 and a switch retainer 5 so as to be slightly bent. As a result, ingress of rainwater from the outside can be blocked at this part.

When the operation button 3 is pushed in, the contacts of the switch come into contact with the pattern provided on the substrate 7 to be in an electrically operable state. At this time, the waterproof packing 4 operates in the same manner as the operation button 3 operates. The conical convex portion 11 provided on the waterproof packing 4 has such a shape that the operation button 3 is constantly applied during the stroke length of the operation of the operation button 3 in the direction of returning the operation button 3 to the original position. Has become.
Therefore, when the operating force from the operation button 3 is removed, the operation button 3 returns to its original position by the repulsive force of the switch 6 and the repulsive force of the convex portion 11, and is held and stopped at that position.

Since the bottom surface of the recess 10 provided in the waterproof packing 4 sandwiched between the operation button 3 and the switch 6 is as thin as possible, the presence or absence of the waterproof packing cannot be sensed. There is.

[Effect of device]

According to the present invention, the packing to be installed for the purpose of preventing rainwater is not visible from the outside, and it is possible to add more packing later.

As for operability, it is possible to supply a product whose presence or absence of waterproof packing is hardly affected by operating force.
