Abstract

The utility model relates to a Christmas light set controller, in particular to a waterproof key-press structure for Christmas light set controller, which is characterized in that: two concentric rings (11 and 12) are made around press button holes on inner face of a box cover (1); a conducting rubber sheet (23) is arranged at center at tail end of a rubber press button (24). The utility model is characterized in that: two rings are made at tail end of the rubber press button (24); wherein, the inner ring (21) is clamped between the two concentric rings (11 and 12) of the box cover; the internal wall of the outer ring (25) and the external wall of the outer ring (11) of the box cover form a sealing face. The tail end of the rubber press button of the utility model is fabricated with two rings which, together with the two concentric rings on inner face of the box cover, forms three sealing in fitting; besides, the inner ring external wall of the rubber press button is made with a plurality of rib rings which forms several sealing, thus increasing the service factor for sealing and prolongs the service life of the Christmas light set and the controller.

Description

The Waterproof push-button structure of Holiday lamp control box

Technical field

The utility model relates to the Holiday lamp controller, particularly the improvement of the Waterproof push-button structure of Holiday lamp control box.

Background technology

Festival lamp luster is controlled its automatically circulation flicker of beating by controller, brings multicoloured happy atmosphere and is widely used to environment.But festival lamp luster and controller box arrange mostly in the open, drenched with rain into water easily and cause electrical equipment to damage or short circuit accident.The circuit board of existing controller is installed in the housing that is made of lid and box body, the seam that will join after the assembling is shut, but still need movable the cooperation with lid by the button that block rubber constitutes, as Fig. 1, shown in Figure 2, be shaped on the concentric enclosure 11 of twice around the button hole of lid 1 inner face, 12, the tail end of rubber button 24 is shaped on one enclosure 21, its center is a conductive rubber slice 23, enclosure snaps between the concentric enclosure of twice of lid, therefore lateral wall has certain waterproof sealing effect in the rubber enclosure, but because the frequent stressed activity of rubber button, the sealing after use a period of time between hat enclosure and the concentric enclosure of twice can be damaged and seep water.

Summary of the invention

The utility model provides a kind of Waterproof push-button structure with Holiday lamp control box of better sealing effectiveness in order to overcome the defective of prior art.

The technical scheme of described water proof type Holiday lamp controller is: a kind of Waterproof push-button structure of Holiday lamp control box, be shaped on the concentric enclosure of twice around the button hole of lid inner face, the tail end center of rubber button is a conductive rubber slice, the tail end that it is characterized in that rubber button is shaped on the twice enclosure, between the concentric enclosure of twice that wherein interior enclosure snaps in described lid, the periphery ring outer wall of the inwall of periphery ring and lid constitutes sealing surface.

The interior enclosure outer wall of described rubber button is shaped on the rib ring.

The tail end of the rubber button of the utility model Holiday lamp controller box is made the twice enclosure, constituting three seals with the concentric enclosure of the twice of lid inner face cooperates, the interior enclosure outer wall of rubber button is shaped on multiple tracks rib ring in addition, form multi-sealed, increase the sealing safety factor, safe in utilization, prolonged service life of festival lamp luster and controller.

Description of drawings

Fig. 1 is the front view of Holiday lamp control box lid;

Fig. 2 is the A-A sectional view of Fig. 1, has represented the hermetically-sealed construction of existing rubber button;

Fig. 3 is the A-A sectional view of Fig. 1, has represented the hermetically-sealed construction of the utility model rubber button.

The specific embodiment

As Fig. 1, shown in Figure 3, the Waterproof push-button structure of embodiment Holiday lamp control box, lid 1 structure is identical with prior art, be shaped on the concentric enclosure of twice around the button hole of its inner face, tail end center bonding one deck conductive rubber slice 23 of rubber button 24, switch contact in this conductive rubber slice 23 and the box on the wiring board over against, press the button, produce strain owing to the rubber layer around the conductive rubber slice 22 is thin, conductive rubber slice 23 contacts the on-off of finishing circuit with switch contact on the wiring board.The tail end of rubber button 24 is shaped on the concentric enclosure of twice, between the

concentric enclosure

11,12 of the twice that wherein interior enclosure 21 snaps in described lid 1 in opposite directions, constitute the two seals face, the periphery ring 11 of lid snaps between the

concentric enclosure

21,25 of twice of rubber button 24 in opposite directions, and the inwall that makes rubber button periphery ring 25 constitutes sealing surface again with periphery ring 11 outer walls of lid.Interior enclosure 21 outer walls of rubber button are shaped on 2-3 road rib ring 211, and periphery ring 11 inwalls of rib ring and lid constitute the multiple tracks linear sealing again, have more strengthened sealing effectiveness.

Claims
