Abstract
The utility model relates to an electric meter waterproof button, which comprises a button cap that is arranged inside a cover button cavity, and the lower part of the button cap is connected with a silicon rubber key, and a reversing-hook convex post on the button cover stretches into the cavity of the meter cover, and the reversing-hook convex post is tightly matched with the cavity. The button has good waterproof performance.
Description
(1) technical field
The utility model relates to a kind of ammeter waterproof press-button.
(2) technical background
In the anti-water quality standard of ammeter industry, the general requirement is IP51, IP52, IP53, and specific requirement is to prevent dust, prevent steam.What mostly use is the button of band spring, owing to there is the free gap, under tighter IP54 required, the button of this structure was under the environment of straight trickle, and secondly unavoidable water inlet, has at button under the situation of knot water and operate, knot water and easily be squeezed into housing.
For this reason, need to adopt a kind of novel, easy operating, cheap waterproof press-button.
(3) summary of the invention
The utility model will overcome the shortcoming of the easy water inlet of button of existing ammeter, has proposed the better press-button structure of a kind of airtight waterproof.
Ammeter waterproof press-button described in the utility model, comprise that being arranged on table covers the interior button cap of button cavities, it is characterized in that: the bottom of described button cap connects silica gel keys, described silica gel keys bottom is connected with button cover, barb projection on the described button cover stretches in the cavity of table lid, described barb projection and described cavity wringing fit.
Further, the inwall wringing fit of the top of described silica gel keys and the lower cavity of button cap, the bottom of described silica gel keys has evagination fast, and described outer projection cooperates with the step of table lid.
Further, the described button cap outside is provided with and prevents that it from dropping out the barb of table lid.
The utility model is by pressing reaches the seal isolation of the microswitch under button and the silica gel keys to silica gel keys.Silica gel keys is covered the purpose that wringing fit (or gluing connecing) reaches the pressing silica gel keys by two open hollow posts on the button cover and table.Owing to be provided with waterproof construction between button cap and the microswitch, can stop the phenomenon of switch water inlet.
The utility model has the advantages that: water resistance is good, easy to assembly, is applicable to production in enormous quantities, and can adapt to high and low temperature environment, and anti-electric shock has good reliability and durability.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model
(5) embodiment
With reference to accompanying drawing, waterproof press-button described in the utility model, comprise table cover 1 button cavities 11, the anti-button cap 2 that drops out, as the silica gel keys 3 of button actions, and be used as the button cover 4 of silica stationary.
Inwall 21 wringing fits of the lower cavity of the top of described silica gel keys 3 and button cap 2, the bottom of described silica gel keys 3 have evagination fast 31, and described outer projection 31 cooperates with the step 13 of table lid.Described button cap 2 outsides are provided with and prevent that it from dropping out the barb 22 of table lid.
Silica gel keys is covered wringing fit (or gluing connecing) by two open hollow posts on the button cover with table and is reached sealing effectiveness, and button cap covers by the loose fit push table, button cap inner chamber and silica gel keys wringing fit, and the outer ring overhead kick prevents that button cap from dropping out the table lid.During use, press button cap, silica gel keys is descending, can touch the microswitch that is installed under the silica gel keys; Decontrol button cap, silica gel keys is from resetting, and microswitch resets thereupon.
The described content of this instructions embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment is stated, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
Claims (3)
1, ammeter waterproof press-button, comprise that being arranged on table covers the interior button cap of button cavities, it is characterized in that: the bottom of described button cap connects silica gel keys, described silica gel keys bottom is connected with button cover, barb projection on the described button cover stretches in the cavity of table lid, described barb projection and described cavity wringing fit.
2, ammeter waterproof press-button as claimed in claim 1 is characterized in that: the inwall wringing fit of the top of described silica gel keys and the lower cavity of button cap, and the bottom of described silica gel keys has evagination fast, and described outer projection cooperates with the step of table lid.
