Abstract

A water-proof type controller of festival lamps is especially applicable to the control of a rainbow tube and belongs to the fitting of lighting electric appliance. A casing consists of a casing body, a front cover and a connection cover. A circuit board is installed inside the casing. The front cover is equipped with a switch hole, and switch buttons are installed inside the switch hole. Wire joints are installed in the casing body and in a connection port of the connection cover. A seal cover is installed outside the buttons in the switch hole. The seal cover and the button are added together to make dual-seal and improve the waterproof effect of the controller. The installation of the seal cover strengthens the appearance beauty of the controller and provides a comfortable handle when pressing the switch.

Description

Water proof type Holiday lamp controller

Technical field

The utility model relates to the Holiday lamp controller, is specially adapted to the control of rainbow tube, belongs to the electric lighting accessory.

Background technology

Holiday lamp is a kind of lamp string of group combination, is controlled by director demon when luminous, and Automatic Cycle is beated, and each lamp gets brighter gradually dark, and star flicker presents colorfully, brings dense happy atmosphere to environment, therefore is widely used.But existing Holiday lamp causes electric shock accidents easily because joint is a lot, so be developed to " rainbow tube " at present, it is totally-enclosed in insulated tube, fool proof to be about to the lamp string, and characteristics such as be not made of salt.Thereby a new problem occurred, the water inlet that is exactly controller does not solve as yet fully.The circuit board of existing controller is installed in the shell, shut after the shell assembling, the switch hole that only stays is cooperated by the button of electro-insulating rubber piece, the cylindrical outer wall of electro-insulating rubber button and the switch hole of shell play certain sealing function, only rely on the electro-insulating rubber piece during switch protruding chew and outside cylinder between the strain that produces of coupling part, protruding chewing with the switch of circuit board conflicted, this structure has certain waterproof effect, but be sealed and matched owing to have only together, safety factor is few, in case water inlet directly arrives in the controller circuit board, so this partly is the weak link of whole rainbow tube and controller waterproof.

Summary of the invention

The utility model provides a kind of water proof type Holiday lamp controller that multiple-sealed device is arranged in order to overcome the defective of prior art.The technical scheme of described water proof type Holiday lamp controller is: the shell of being made up of housing, protecgulum and link cover of FIG, mounting circuit boards in the shell, in protecgulum, be shaped on switch hole, shift knob is installed in the switch hole, in the connection jaws of housing and link cover of FIG, power lug is installed, it is characterized in that seal closure is installed in the button outside in the switch hole.Seal closure is shaped on embraces ring, embraces in the two sides of ring, and its one side is connected with the bulge loop of protecgulum, and another side matches with button, is to squeeze between.And seal closure is shaped on convex tendon, is shaped on groove in the protecgulum, and convex tendon is pacified in the groove and to be cooperated closely.Described seal closure is that elastomeric material is made, and is flexible.Long cassette connecting hose is installed as power lug in the connection jaws of housing and link cover of FIG, intensity and sealing property are improved.There has been seal closure the button outside of Holiday lamp controller, and the one, prevent that rainwater from entering, play dual-seal, increase safety factor, safe in utilization, relieved, especially supporting with totally enclosed rainbow tube Holiday lamp, improve total quality.Overcome weak link.The 2nd, the design of seal closure is tight with cooperating of protecgulum and button, especially seal closure embrace ring both of fixed cover when assembling itself, play the gasket seal effect again.The 3rd, there had seal closure to increase controller to be aesthetic in appearance.The 4th, Push switch, finger promotes button, comfortable feel through seal closure.The 5th, seal closure is made by elastomeric material, insulation, good airproof performance, long service life.

Embodiment

The utility model relates to water proof type Holiday lamp controller, mainly is at the improvement design of the power lug of the shift knob of controller and connection jaws, promptly in the outside of shift knob seal closure is installed, and long cassette connecting hose is adopted in power lug.Usually be made of plastics housing 11, protecgulum 9 and link cover of FIG 16 and form controller housing, mounting circuit boards 10 in the shell, be shaped on switch hole 15 in the protecgulum 9, switch hole has switch enclosure 8 to constitute, and button 7 is installed in the switch hole, button 7 is made by elastomeric material, the cylindrical outer wall of button matches with switch hole 15, and the center is shaped on that button is protruding chews 13, and the protruding switch contact site 12 that arrives to circuit board 10 of chewing is finished the control circuit on-off, and promote button is the outer end, is as shown in Figure 1 and seal closure 6 auxiliary sections.Prior art finger directly promotes button 7, made by 14 distortion of button strain portion protrudingly to chew 13 and contact with circuit board 10, so button 7 and switch hole 15 seal degrees is limited and can leak, and external form is not attractive in appearance yet.Now seal closure 6 is installed in 7 outsides of the button in switch hole, seal closure 6 is made by elastomeric material, and it is shaped on and embraces ring 4 in conjunction with as Fig. 1, shown in Figure 3, embrace between the cylinder end face 23 that ring is positioned on the bulge loop 25 of protecgulum 9 and button 7, and in protecgulum 9, be shaped on groove 24, and seal closure 6 is shaped on convex tendon 5, and convex tendon 5 embeds in the groove 24, the bulge loop 25 of protecgulum is embraced at the seal closure edge like this, cooperate closely, and embrace ring 4 and be equivalent to the pad effect again, sealing, waterproof effect are splendid.Just (preceding) face of slave controller sees that seal closure has been arranged simultaneously, and as Fig. 1, Fig. 2 and shown in Figure 3, external form is very attractive in appearance.Dividing plate at housing 11 is the outside line coupling part below 3, the lead-in wire 17 of lead is connected on the circuit board 10, housing 11 is shaped on wiring bayonet socket 2, link cover of FIG 16 is shaped on wiring bayonet socket 19, the interior ring 18 of joint of long cassette connecting hose 21 is installed in the

wiring bayonet socket

2,19, and joint outer shroud 20 is pressed on link cover of FIG and the housing end face 1, inside and outside clamping, tension, sealed waterproof effect are good, and long cassette connecting hose 21 has increased lead 22 linking intensities, and the whole class of product is improved.
