Abstract
A water-proof structure of keyboard comprises an upper cover, a lower cover connected with the upper cover and a seal ring arranged between the upper cover and the lower cover, wherein the upper cover is provided with a connecting column, a through hole is arranged on the connecting column, the lower cover is provided with a connecting hole, and the connecting column can be inserted in the connecting hole, and the seal ring is arranged between the connecting column and the lower cover. The water-proof structure prevents water from flowing into the lower cover because of a capillary phenomenon when water is discharged from a through hole through arranging the through hole on the connecting column and arranging the seal ring between the connecting column and the lower cover, thereby achieving more reliable water prevention.
Description
Technical field
The utility model relates to a kind of keyboard, relates in particular to a kind of waterproof construction of keyboard.
Background technology
Along with the development of information technology, various electronic products are widely applied in daily life and the work, for example computer.And keyboard also uses widely because of a kind of typical input equipment as electronic product.General keyboard comprises: loam cake is provided with opening; Lower cover can be fixed by plurality of fixed device and loam cake; The keyboard group is contained in the opening of loam cake; And circuit board group, be located between keyboard group and the lower cover by positioner.This circuit board group includes the printed circuit board (PCB) and the film circuit board of rigidity, on printed circuit board (PCB), be provided with contact terminal outside being exposed to electrically connecting, and this link and contact terminal are fixed link together by the device that pushes against between the upper and lower covers with the link of film circuit board.In use, occur the situation of keyboard water inlet sometimes, therefore, designed the waterproof construction of keyboard.
As shown in Figure 1, existing common keyboard waterproof organization plan is to be provided with joint pin 102 at keyboard loam cake 100, joint pin 102 is provided with through hole 104, and keyboard lower cover 200 is provided with a connecting hole 202, this joint pin 102 can insert connecting hole 202, and like this, the water of keyboard loam cake 100 can flow down along through hole 104, thereby reach the effect of draining, this structure was used on keyboard a lot of years.Yet, use for many years finds that there is a very big problem in this structure, that is exactly that water is after through hole 104 flows out, because of capillarity, water can be along the gap between joint pin 102 and the connecting hole 202 toward the upper reaches, thereby cause under the keyboard and covered water, this has adverse influence to the circuit board between keyboard loam cake 100 and the lower cover 200, obviously is necessary to improve.
The utility model content
The purpose of this utility model is to provide a kind of waterproof construction of keyboard, prevent capillarity by sealing ring is set, thereby waterproof is more reliable.
For being implemented in above-mentioned purpose, the utility model provides a kind of waterproof construction of keyboard, comprise loam cake, the lower cover that is connected with loam cake and be arranged at loam cake and lower cover between sealing ring, on be covered with joint pin, joint pin is provided with through hole, under be covered with a connecting hole, this joint pin can insert connecting hole, sealing ring is located between joint pin and the lower cover.
Free end at joint pin is provided with the ring-type breach, thereby forms a shoulder on joint pin, and sealing ring is resisted against on this shoulder.
Be provided with an annular protrusion at connecting hole towards the peritreme extension of loam cake, the relative shoulder setting of this projection it is pushed against on sealing ring, thereby sealing ring is arranged between projection and the shoulder.
The sealing circle is a rubber washer.
The beneficial effects of the utility model:, water anti-sealing when through hole is discharged is being flowed into lower cover because of capillarity, thereby realizing that waterproof is more reliable by through hole being set at joint pin and between joint pin and lower cover, sealing ring being set.
In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effect apparent by embodiment of the present utility model is described in detail.
In the accompanying drawing,
Fig. 1 is the schematic diagram of the waterproof construction of existing keyboard;
Fig. 2 is the schematic diagram of the waterproof construction of the utility model keyboard.
Embodiment
For further setting forth technological means and the decorative effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
As shown in Figure 2, the waterproof construction of the utility model keyboard comprise loam cake 2, the lower cover 4 that is connected with loam cake and be arranged at loam cake and lower cover between sealing ring 6.Loam cake 2 is provided with joint pin 22, and joint pin 22 is provided with through hole 24, thereby and be provided with ring-type breach 26 at the free end of joint pin 22 and on joint pin 22, form a shoulder 28, sealing ring 6 is resisted against on the shoulder 28.
Lower cover 4 is provided with a connecting hole 42, and this joint pin 22 can insert connecting hole 42, and like this, the water of keyboard loam cake 2 can flow down along through hole 24, thereby reaches the effect of draining.Sealing ring 6 is located between joint pin 22 and the lower cover 4.
Be provided with an annular protrusion 44 at connecting hole 42 towards the peritreme extension of loam cake 2, these projection 44 relative shoulders 28 are provided with, make it push against sealing circle 6, thereby sealing circle 6 is arranged between projection 44 and the shoulder 28, thereby can prevent sealing after through hole 24 flows out because of capillarity along the gap between joint pin 22 and the connecting hole 42 past upper reaches, thereby waterproof is more reliable.
Sealing circle 6 is a rubber washer.The projection 44 of lower cover 4 is the force intensitys that are subjected in order to increase lower cover 4 and to cooperate with loam cake 2.
In sum, the utility model is flowing into lower cover with water anti-sealing when through hole is discharged because of capillarity, thereby is realizing that waterproof is more reliable by through hole being set at joint pin and between joint pin and lower cover sealing ring being set.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model accompanying Claim.
