Abstract
The utility model discloses a kind of switching protective device; including the circuit board being set up in housing, the switch for being arranged at the board edge, the button being oppositely arranged with the shake-up face of the switch and be sheathed on the button exposed junction protection cap; the key hole of the exposed junction of the button and the housing is slidably matched, and the end face of one end that the protection cap is engaged with the exposed junction of the button and the confined planes of the button bore edges are coplanar.With this structure design, it can effectively prevent from carrying with transportation in product, touch button, and then cause the maloperation of switch by the setting of protection cap.
Description
Technical field
It the utility model is related to technical field of electronic products, more particularly to a kind of switching protective device.
Background technology
Typically be connected under prior art for the touch switch of LED with outside rubber button, due to touch-switch compared with
To be sensitive, gently touch rubber button will lightening LED lamp, if product carry and transportation in, accidentally collide
Rubber button, LED will be caused to be constantly in illuminating state, in turn result in power loss built in LED, then influenceed product and go out
Kinds of goods matter.
Utility model content
The purpose of this utility model is to provide a kind of switching protective device that can effectively prevent incorrect switching.
To use following technical scheme up to this purpose, the utility model：
A kind of switching protective device, including be set up in housing circuit board, be arranged at the board edge switch,
The button that is oppositely arranged with the shake-up face of the switch and be sheathed on the button exposed junction protection cap, the button
The key hole of exposed junction and the housing be slidably matched, one end that the protection cap is engaged with the exposed junction of the button
End face and the confined planes of the button bore edges are coplanar.
Wherein, the button includes flexible piece, and is embedded in the flexible piece relative with the shake-up face of the switch one
The hard member at end.
Wherein, the flexible piece uses TPE flexible glue material integrated injection moldings, and the hard member uses makrolon ebonite
Material integrated injection molding.
Wherein, the flexible piece is arranged to flexible piece of rubber, and the hard member is arranged to hard polycarbonate plastic parts.
Wherein, the protection cap and the exposed junction of the button are detachably connected.
Wherein, the protection cap is arranged to hard plastic part.
Wherein, the switch is arranged to touch switch.
The beneficial effects of the utility model：The utility model include be set up in housing circuit board, be arranged at the electricity
The switch of road edges of boards edge, the button that is oppositely arranged with the shake-up face of the switch and the exposed junction for being sheathed on the button
Protection cap, the key hole of the exposed junction of the button and the housing are slidably matched, and the protection cap is exposed with the button
Hold the end face and the confined planes of the button bore edges of the one end being engaged coplanar.With this structure design, protection cap can be passed through
Setting, effectively prevent from carrying in product and transportation in, touch button, and then cause the maloperation of switch.
Brief description of the drawings
Fig. 1 is a kind of front view of switching protective device of the utility model.
Fig. 2 is the sectional view in AA sections in Fig. 1.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
As depicted in figs. 1 and 2, a kind of switching protective device in the present embodiment, including be set up in housing circuit board 1,
The button 3 and be sheathed on institute that the shake-up face of the switch 2 and the switch 2 that are arranged at the edge of circuit board 1 is oppositely arranged
The protection cap 4 of the exposed junction of button 3 is stated, the exposed junction of the button 3 is slidably matched with the hole of button 3 of the housing, the guarantor
The end face of one end that protecting cover 4 is engaged with the exposed junction of the button 3 and the confined planes of the bore edges of button 3 are coplanar.
Further, in the present embodiment, the button 3 includes flexible piece, and is embedded in the flexible piece and is opened with described
The hard member of the shake-up face opposite side of pass, the flexible piece use TPE flexible glue material integrated injection moldings, and the hard member is adopted
With makrolon ebonite material integrated injection molding, the flexible piece is arranged to flexible piece of rubber, and the hard member is arranged to hard
Matter makrolon plastic parts, the switch are arranged to touch switch.In present embodiment, flexible piece may be arranged as silica gel
Button, hard member may be arranged as the other materials such as nylon plastic parts, with this structure design, effectively flexible piece can be avoided to exist
During long-term pressing, cause to grasp with buttons caused by reason such as one end material aging of the shake-up face joint of switch, failures
Make without feel, the generation for situations such as key press fails, the setting of hard member, easily it can be changed, and it is firm
It is durable, effectively lift the operating handle of button.
In the present embodiment, the protection cap 4 and the exposed junction of the button 3 are detachably connected, and the protection cap 4 is arranged to
Hard plastic part, in use, protection cap is removed.
Technical principle of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the limitation to scope of protection of the utility model can not be construed in any way.Based on explanation herein,
Those skilled in the art, which would not require any inventive effort, can associate other embodiments of the present utility model,
These modes are fallen within the scope of protection of the utility model.
