Abstract
The utility model provides a waterproof structure for a key switch. The waterproof structure for the key switch is disposed on a casing, and is suitable for an electronic device. The waterproof structure for the key switch is composed of a key, an elastic body and a support member; the key is disposed on the casing, and a user presses the key to fulfill a function of the electronic device; the elastic body covers the casing and is disposed between the casing and the key, when the key is pressed, the key is directly contacted with the elastic body, and force applied by the pressing is transmitted by the elastic body and further pressed to a pressing switch; and the support member is installed on the elastic body and used for fixing the elastic body, so that the shape of the elastic body cannot change when the key is pressed. The casing and the support member are mutually cooperated, the elastic body is stably positioned between the casing and the support member, so that waterproof purpose is achieved due to the fact that a position where the elastic body and the casing are directly contacted is deformed due to pressing of the elastic body.
Description
[Ji Intraoperative field]
The utility model relates to the key switch waterproof construction on electronic product.
[Bei Jing Ji Intraoperative]
On electronic product, be provided with key switch in order to operate control more, as input character and numeral and various input instructions, but entering electronic product inside, the existence of key switch feedwater point provides some spaces, for electronic product, the such as portable electron device such as mobile phone or portable radio, some have the electronic product of waterproof demand to avoid moisture to enter as mobile phone etc. need to arrange some waterproof constructions at key switch place, conventionally the structure adopting is in electronic product casing, to be provided with push switch, and position corresponding with push switch on housing is provided with through hole, through hole seals by water-proof silica-gel cap, and then keycap support by depressing, touch the switch on mainboard by water-proof silica-gel cap, realize switch motion, because the material of silica gel is soft, intensity and poor toughness, what support at keycap is easy to break by depressing repeatedly, thereby affect case feel, the water resistance of operation control and mobile phone.
[summary of the invention]
Therefore, the purpose of this utility model is mainly to provide a kind of intensity high, the simple and reliable for structure and well behaved key switch waterproof construction of assembly operation.
For achieving the above object, the utility model provides a kind of key switch waterproof construction, is located on a casing, be applicable to an electronic installation, formed by button, elastomer and strutting piece, wherein, button is located on casing, and user realizes the function of electronic installation by pressing keys; Elastomer covers on casing, is located in the middle of casing and button, and in the time of pressing keys, the direct contact resilient body of button, thus the active force of being pressed by elastomer transmission is further pressed into push switch; Strutting piece is installed on this elastomer, fixes this elastomer, and while making to press this button, this elastomeric shape can not change.
Especially, described elastomer is circular projection near the part of button, and it is inner that this strutting piece is located at this circular projection, to support this elastomer.
Especially, when described elastomer is extruded, produce compression.
Compared to prior art, key switch waterproof construction of the present utility model, cooperatively interact by casing and strutting piece, elastomer is stable in the middle of the two, make position that elastomer directly contacts with casing because elastomeric crimp reaches the object of waterproof, intensity is higher, simple and reliable for structure and assembly operation is functional.
[accompanying drawing explanation]
Fig. 1 is the explosive view of the utility model key switch waterproof construction;
Fig. 2 is the overall schematic of the utility model key switch waterproof construction.
[embodiment]
Below, by reference to the accompanying drawings shown in, specific embodiment of the utility model is elaborated:
The utility model provides a kind of key switch waterproof construction, cooperatively interact by casing and strutting piece, elastomer is stable in the middle of the two, make position that elastomer directly contacts with casing because elastomeric crimp reaches the object of waterproof, refer to Fig. 1, for the explosive view of the utility model key switch waterproof construction, as shown in the figure, described key switch waterproof construction is located on casing 1, be applicable to an electronic installation, this key switch waterproof construction comprises button 4, elastomer 3 and strutting piece 2, refer to Fig. 2, for the overall schematic of the utility model key switch waterproof construction, as shown in the figure, button 4 is located on described casing 1, user realizes the function of this electronic installation by pressing this button 4, elastomer 3 covers on this casing 1, and this elastomer 3 is located in the middle of described casing 1 and button 4, and in the time pressing this button 4, the direct contact resilient body 3 of this button 4, is further pressed into push switch 5 thereby transmit by elastomer 3 active force of pressing, it is installed in strutting piece 2 on this elastomer 3, fixes this elastomer 3, and while making to press this button 4, the shape of this elastomer 3 can not change.
In the present embodiment, described elastomer 3 is circular projection near the part of button 4, and it is inner that this strutting piece 2 is located at this circular projection, and to support this elastomer 3, and described elastomer 3 produces compression while being extruded.
In the present embodiment, cooperatively interact by casing 1 and strutting piece 2, elastomer 3 is stable in the middle of the two, make position that elastomer 3 directly contacts with casing 1 because the crimp of elastomer 3 reaches the object of waterproof.
By reference to the accompanying drawings embodiment of the present utility model and embodiment are described in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken possessing those skilled in the art, can also make a variety of changes without departing from the concept of the premise utility.
