Abstract
The utility model discloses a kind of dial switch electrostatic protection apparatus, this device comprises the dial switch of front end with keyseat, and the front side of keyseat is provided with button and digital display screen, and this device also comprises gas phase gel protective sleeve; This gas phase gel protective sleeve covers keyseat and button, and this gas phase gel protective sleeve neighboring is fixed on the outer wall of dial switch; This gas phase gel protective sleeve is with the keycap coordinated with described button one_to_one corresponding and the transparent windows just right with described digital display screen.The neighboring of gas phase gel protective sleeve is provided with retaining mechanism.Protective jacket main body adopts gas phase silica gel material, has fabulous electrical insulation properties and high-low temperature resistant impact property, and good springiness, is more suitable for the larger feature of dial switch key journey, better as keycap followability.Relative to prior art, adopt the utility model to not only increase esd immunity, play dustproof effect simultaneously, substantially increase system reliability.
Description
Technical field
The utility model relates to a kind of special purpose device being mainly used in carrying out dial switch electrostatic defending.
Background technology
In single-chip computer control system, input equipment is essential.It is simple that dial switch has interface, data can latch, easy to operate intuitively, be easy to the features such as installation, therefore in the system of a small amount of controling parameters of needs and data, often adopt dial switch.In some technical specification of electric power system, particularly explicitly call for equipment can arrange system parameters in the uncharged situation of device, therefore dial switch just becomes a kind of common input equipment.
During actual use, be generally that one or more pieces dial switch are used in combination.But because the structure of dial switch limit, between dial switch and dial switch key part be easily subject to electrostatic interference cause Single Chip Microcomputer (SCM) system reset or damage.Current dial switch is generally unshielded, not only can not antistatic, and easily enters dust, and the situation causing dial switch to lose efficacy happens occasionally.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of dial switch electrostatic protection apparatus, for carrying out electrostatic defending to dial switch, to improve the reliability of dial switch and affiliated control system thereof.
The technical solution of the utility model is as follows:
A kind of dial switch electrostatic protection apparatus, comprise the dial switch of front end with keyseat, the front side of keyseat is provided with button and digital display screen, it is characterized in that: also comprise gas phase gel protective sleeve; This gas phase gel protective sleeve covers keyseat and button, and this gas phase gel protective sleeve neighboring is fixed on the outer wall of dial switch; This gas phase gel protective sleeve is with the keycap coordinated with described button one_to_one corresponding and the transparent windows just right with described digital display screen.
As further improvement of the utility model: the neighboring of gas phase gel protective sleeve is provided with retaining mechanism.
Good effect of the present utility model is: protective jacket main body adopts gas phase silica gel material, has fabulous electrical insulation properties and high-low temperature resistant impact property, good springiness, and stretcher strain is strong, and anti-pull intensity is high, not easily deformed damaged.On the other hand, because gas phase silica gel has better elasticity, be more suitable for the feature that dial switch key journey is larger, the keycap followability as overcoat is better.
The utility model protective jacket zone line is transparent windows, is convenient to observe the numeral on dial switch.
The utility model, with protective jacket retaining mechanism, can be anchored on unlikely on dial switch coming off by the utility model.
Relative to the existing dial switch not doing to protect, adopt the utility model to not only increase esd immunity, play dustproof effect simultaneously, substantially increase system reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 B-B to structure cutaway view.
Fig. 3 be in Fig. 1 H-H to structure cutaway view.
Embodiment
As shown in Figure 1 to Figure 3, embodiment of the present utility model comprises the dial switch 5 of front end with keyseat 6, and the front side of keyseat 6 is provided with button 7 and digital display screen.The Outside Dimensions of keyseat 6 is greater than the main part of dial switch 5.
Embodiment of the present utility model also comprises gas phase gel protective sleeve 3.This gas phase gel protective sleeve 3 covers keyseat 6 and button 7, and neighboring is fixed on the main part outer wall of dial switch 5.This gas phase gel protective sleeve 3 is with the keycap 1 coordinated with described button 7 one_to_one corresponding and the transparent windows 2 just right with described digital display screen.
Further, the neighboring of gas phase gel protective sleeve 3 is provided with retaining mechanism 4.
During installation, first dial switch 5, keyseat 6 and button 7 are combined and installed together.Then gas phase gel protective sleeve 3 is set up from front end, keycap 1 is coordinated with button 7 one_to_one corresponding, transparent windows 2 just to the digital display screen on dial switch, gas phase gel protective sleeve 3 stride across keyseat 6 and with dial switch 5 main part wall contacts.Finally the retaining mechanism 4 in gas phase gel protective sleeve 3 is fastened on dial switch.
Claims (2)
