Description

The location structure of the pressure drop element of On line switch

The utility model relates to a kind of switching device in the essential electronic element, refers in particular to a kind of pressure drop element that makes and is convenient to be installed in the interior location structure of On line switch.

On line switch is directly to be located on the electric wire to control the start of electric device, early stage On line switch is only to make current circuit have path or open circuit two kinds of variations, because mostly On line switch is to be applied to the article of desk lamp class, its light that can control only has difference bright, that go out.In recent years You Zhang Kun Mr. strain proposes the application of No. 77200279 patent case, its structure as shown in Figure 1 and Figure 2, its housing 10,11 is interior except installing y-bend pin conducting strip 12,13, other sets up one and touches a conducting strip 14 and a pressure drop element 15, makes this pressure drop element 15 connect this and touches a conducting strip 14 and a fork pin conducting strip 13.When dialling commentaries on classics knob 16, this knob 16 is in three sections stepping positions, be to make it rotate conducting strip 17 except conducting or this y-bend pin conducting strip 12,13 of not conducting, with the formation path or outside opening circuit, in addition but conducting this fork pin conducting strip 13 and this touch conducting strip 14, make power supply transfer to conducting strip 14 via conducting strip 13, pass through the pressure drop of this pressure drop element 15, be transmitted in electrical equipment by conducting strip 12 again, form the output of a half-power.By this, the variation of its power output is promoted in three sections outputs such as make On line switch have total power, half-power and to open circuit, and improves the shortcoming of conventional On line switch.

Above-mentioned structure really can make On line switch have the more variation of multistage, and have more practical function, but the shortcoming of still having in the structure of case before this patent is further improved, lid: this a fork pin conducting strip 13 and an end that touches conducting strip 14 are respectively establishes a coiling portion 131,141, in respectively should respectively having embedding hole 132,142 in the coiling portion 131,141,151 at two ends of pressure drop element 15 are plugged in respectively in this two embeddings hole 132,142, and are connected with this two conducting strip 13,14.

Show that according to actual experience the shortcoming of above-mentioned structure is: because these conducting strips the 13, the 14th, the lamellar body that body is narrow and small desires to bend out coiling portion 131,141 realities of these small-bores when being difficult for the defect rate height again on conducting strip.Moreover, owing to after coiling portion 131,141 is bent into type, still can have outer elasticity of opening, make the aperture in embedding hole 132,142 greater than the diameter of the end 151 of pressure drop element 15, therefore, pressure drop element 15 promptly very easily respectively comes off on this conducting strip 13,14, and can't reach result of use.

Except above-mentioned structure, industry also has with Type of Welding and connects this pressure drop element and conducting strip, also be need not those coiling portions 131,141 on the above-mentioned graphic conducting strip 13,14, directly pressure drop element two ends are welded in this two conducting strip 13,14 respectively, but so also increased the cost of welding robot and fixture, and its assembling speed is also comparatively slow.

The purpose of this utility model be to propose a kind of mainly by fork pin conducting strip, contact the location structure of the pressure drop element of the On line switch that reed, pressure drop element, spirally-controlled button and conduction arc sheet formed, it is simple and convenient assembly not only, the pressure drop element can more firmly be connected with conducting strip, and can be in order to avoid use the welding machine tool, simplify fabrication schedule, reduce cost, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it includes: a upper shell; One lower house, it is corresponding to this upper shell, and it and this upper shell cover mutually, its inner tool one accommodation space, and Yu Yiduan offers a breach; One first and second fork pin conducting strip, its body body one end is respectively established a haptic element, and this two conducting strip is embedded at accommodation space two sides of this lower house respectively;

One contacts reed, and it is located in this accommodation space, between this y-bend pin conducting strip;

One pressure drop element, it also is located in this accommodation space, and its two end is connected to this and contacts reed and this second fork pin conducting strip;

One spirally-controlled button, it is in the form of annular discs, and a ratchet is established in its lower surface, and this ratchet has some double wedges, and this spirally-controlled button is located between this upper and lower casing, and its periphery is protruding to be exposed to outside this breach, changes for dialling; This ratchet system is arranged in this accommodation space;

One conduction arc sheet, comprise a body, this body is provided with in some cambered surfaces portion, this conduction arc sheet is to be embedded at this ratchet, this body is to be positioned at this ratchet end face, these cambered surface portions are the outer rims that are covered in these double wedges, form some to insulation double wedge and some to the conduction double wedge so that make this ratchet hit face; These double wedges are the haptic elements that touch this y-bend pin conducting strip; This conduction arc sheet also contacts the spring life with this and touches; The body body of this second fork pin conducting strip is to establish a caulking groove; This sheet body one side that contacts reed is to establish a scarfer, and is corresponding with the caulking groove of this second fork pin conducting strip, establishes a caulking groove in this scarfer again; These pressure drop element two ends are embedded in this fork pin conducting strip respectively and this contacts in the caulking groove of reed.

The effect that architectural feature of the present utility model is reached is:

One, for On line switch, the utility model is to innovate scarfer and caulking groove are set on the conducting strip of On line switch, makes the pressure drop element be embedded in conducting strip and locatees, and its structure is different from conventional On line switch, is the initiative of On line switch.

Two, pressure drop element 65 is the caulking grooves 59,64 that directly are embedded in conducting strip with its bar portion 66, assembling fast, and the pressure drop element more firmly is connected with conducting strip, can not become flexible.

Three, for assembling pressure drop element, except installation work fast, also need not buy more welding facility, fixture cost.Moreover, the scarfer 63 of conducting strip and caulking groove the 59, the 64th, one-body molded with conducting strip, need not go coiling portion 131,141 with the conventional conducting strip of facility bendings again, can simplify manufacture process and reduce cost.
