Description

The improvement structure of diverter switch

Technical field

The utility model relates to a kind of structure of diverter switch, refers to especially a kind ofly need not the winding electric wire, and then has ease of assembly and the Switch structure that reduces manufacture cost and other advantages and effect concurrently.

Background technology

General electric equipment is mostly controlled its energising and off-position by diverter switch, and be for "on" position or for off-position for making things convenient for the user to differentiate diverter switch easily afterwards, then there is the dealer to research and develop the design that luminous element is set in diverter switch inside, whether shinny by visual luminous element, it is for " on " or for " off " state that the user can understand described diverter switch easily.

And the Switch structure of existing tool illumination effect generally as shown in Figure 1 (this case be quote No. 5105059 patent case of the U.S. as a setting technology be illustrated), mainly comprise members such as lower base 10, clamping block 20, upper pedestal 30 and pressing tablet 40, wherein, described lower base 10 both sides outside wall surface are convexly equipped with clipping block 101 respectively, and lower base 10 inside are provided with storage tank 102 to establish conducting strip 103, elastic parts 104 and link piece 105; Described clamping block 20 tops are arranged with a slot 201, and the bottom then plugs down to the fore-set 202 that extends; Described upper pedestal 30 tools one centre bore 301, centre bore 301 sides then are provided with perforation 302 and set firmly wherein for luminous element 50 (for example bulb), and upper pedestal 30 both sides are to extend the slightly flexible fin 303 of tool of a slice respectively downwards, are to offer clip hole 304 on the fin 303; Described pressing tablet 40 is to be composited by light-transmitting materials and light tight material, and its light-transmitting materials right position is in luminous element 50 tops, and pressing tablet 40 bottom surfaces are convexly equipped with an inserted link 401 downwards and are to be plugged in the slot 201 of clamping block 20.During assembling, must be connected to form conduction state with elastic parts 104 by first conductive connecting pin 501 (being generally copper cash) with luminous element 50, fore-set 202 with clamping block 20 bottoms is pressed against link piece 105 tops again, then upper pedestal 30 and lower base 10 are covered and utilize clip hole 304 and clipping block 101 to detain fixed closing mutually, inserted link 401 with pressing tablet 40 inserts the slot 201 of clamping block 20 and makes pressing tablet 40 clips at upper pedestal 30 at last, promptly constitutes diverter switch as shown in the figure.

But, the utility model designer studies the back at above-mentioned existing diverter switch and finds, the conductive connecting pin 501 of existing luminous element 50 must form with conducting strip 103 with elastic parts 104 and link, can make luminous element 50 switch and flicker synchronously with the electric power of diverter switch, but because described luminous element 50 is less with the volume of elastic parts 104 members such as grade, the phenomenon that therefore inconvenience of taking easily arranged in assembling process, adding its conductive connecting pin 501 is to pull strings with manual operation to impose solder joint again to elastic parts 104 places, therefore artificial careless mistakes such as welding precision deficiency are arranged easily, and then cause conducting electricity problem such as loose contact and produce, in addition, the copper material expense of its conductive connecting pin 501 also tends to cause dealer's materials cost burden.

In view of this, the utility model designer satisfies and drops into research and development and test with great concentration based on being engaged in related industry practical experience for many years, has the utility model to come out eventually.
