Abstract
A safety device capable of direct changed for light modulator comprises a safety tube support (1), a safety tube seat (2), wherein the safety tube support (1) is arranged on a line board (6) and is connected with lines; a safety tube (3) is clipped in the safety tube seat (21) and is integrated with a safety tube seat body (21) as a whole, when the safety tube (3) needs to be changed, the safety tube seat (2) can be directly taken out through the square hole (41), (51), (61) in or out of a shell and the safety tube (3) can be changed. The utility model can make users change the safety tube (3) directly, easily, safely and conveniently.
Description
The utility model relates to a kind of protective tube device that is used on the dimmer wiring board, especially need not take shell and inner casing apart, the fuse unit that can directly change.
The dimmer that a kind of lamp decoration voltage high-low regulating is arranged on the current market; the device of one replaceable fuse tube is housed on its wiring board power circuit; when abnormal conditions take place in output; fusible safe silk during as overload or short circuit; and reach the usefulness of protective circuit; this known safeties structure is by two rubber-like copper intermediate plate welding in the circuit board; again protective tube is placed among two intermediate plates (referring to Fig. 1; A to); when needs are changed protective tube; must take the kirsite shell of light fixture apart; take plastic shell again apart, just can touch wiring board and remove to change protective tube, such layout is very inconvenient to maintenance; general user can't operate, and needs special electrician to operate.
If changing, version is placed on protective tube on the special fuse base, need not take shell and inner casing apart and can directly take out and can directly insert, easily the user has not only improved operating efficiency, also very safe, manufacture and design this safeties and be very important.
The purpose of this utility model is to provide a kind of dimmer that is used for according to above-mentioned, when changing protective tube, needs need not take shell and inner casing apart, the user can be directly easily, safety, change protective tube easily, a kind of safeties that directly to change on the dimmer of being used for that make that maintenance work simplifies greatly.
The purpose of this utility model is achieved through the following technical solutions:
A kind ofly be used for the safeties that dimmer can directly be changed, by protective tube support (1), fuse base (2) is formed, wherein, protective tube support (1) is installed in wiring board (6) and upward is connected with circuit, protective tube (3) is stuck on the protective tube pedestal (21) becomes an integral body, it can pass through kirsite bottom square opening (41), plastic cement bottom square opening (51) and wiring board square opening (61) clip press from both sides on (12) at the silk of protective tube support (1), otherwise can directly extract fuse base (2) from protective tube support (1).
The utlity model has following advantage and effect:
1, safeties of the present utility model can not need be opened shell and inner casing when changing protective tube, outside by housing can directly extract fuse base, take off protective tube from fuse base, change it, make the consumer, can take out the fuse base of plastic cement as long as gently prize the fuse base middle position with a word bottle opener, change good protective tube, again easily, convenient, safety oppositely put back to fuse base.
2, the utility model simple structure is easy to make, and working service is repaired simple and easy.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the known mounting means schematic diagram of safeties in the dimmer
Fig. 2 can directly change the schematic diagram of protective tube mode for the utility model
Fig. 3 is the overall schematic perspective view of the utility model fuse base
Fig. 4 is the utility model protective tube pedestal schematic perspective view
Fig. 5 is the overall schematic perspective view of the utility model protective tube support
Among the figure, 1-protective tube support, 11-support, 12-silk folder, 2-fuse base, 21-pedestal, the 211-draw-in groove, 212-limiting plate, 213-panel, the 3-protective tube, 4-kirsite bottom, 41-kirsite bottom square opening, 5-plastic cement bottom, 51-plastic cement bottom square opening, 6-wiring board, 61-wiring board square opening, 7-kirsite loam cake, 8-plastic cement loam cake
Be described further below in conjunction with drawings and Examples:
By Figure 1A to as can be known, safeties for the replaceable fuse tube installed on the known dimmer wiring board power circuit, when changing protective tube 3, needs need open kirsite loam cake 7 one by one, kirsite bottom 4, plastic cement loam cake 8, plastic cement bottom 5 just can touch protective tube 3, and this version is extremely inconvenient concerning the user.
As shown in Figure 2, the utility model is by protective tube support 1, fuse base 2 is formed, wherein, protective tube support 1 is installed on the wiring board 6 and is connected with circuit, and protective tube 3 is stuck in becomes an integral body on the protective tube pedestal 21, and it can pass through kirsite bottom square opening 41, plastic cement bottom square opening 51 and wiring board square opening 61 clips press from both sides on 12 at the silk of protective tube support 1, otherwise can directly extract fuse base 2 from protective tube support 1.
As shown in Figure 3, fuse base 2 is made up of protective tube pedestal 21 and protective tube 3, and wherein, protective tube pedestal 21 is made by plastic cement, and protective tube 3 is stuck on the protective tube pedestal 21 by draw-in groove 211, and the two is combined as a whole, standby it.
As shown in Figure 4, protective tube pedestal 21, mainly by draw-in groove 211, limiting plate 212, panel 213 is formed, wherein, draw-in groove 211 blocks protective tube 3 by the elasticity of structure, when fuse base 2 snaps in protective tube support 1, limiting plate 212 is used for limiting protective tube 3 and just in time snaps in the fixedly circular arc portion of protective tube 3 of silk folder 12, the requirement that the physical dimension of its panel 213 should satisfy protective tube 3 when putting into and extracting out, the size of being a bit larger tham protective tube 3, height dimension between limiting plate 212 and the panel 213, the outer surface that should satisfy the bottom surface of panel 213 when fuse base 2 is put into structure and kirsite bottom 4 is on same plane.
Illustrated by Fig. 5, protective tube support 1 is made up of support 11 and silk folder 12, and its medium-height trestle 11 and silk folder 12 are all made by the sheet metal that conducts electricity, phosphorus bronze sheet for example, and the two welds together.Support 11 is fixed on the wiring board 6 and is connected with circuit.Utilize the assign to phase mutual edge distance of clip protective tube 3, one double brackets 11 of the elasticity of silk folder 12 and the arc sections on it, should guarantee mariages folder 12 just in time clip on the metal of protective tube 3 heads.
