CN2169933Y - Two-purpose anti-electroshock lamp base for screw and bayonet socket - Google Patents

Abstract

A two-purpose anti-electroshock lamp base for screw and bayonet socket is characterized in that each electric pole protruded from a lamp base is not directly connected with the positive and negative connecting electric slices in the cover before the lamp cap not being mounted by the action of the compression spring bunted by an insulating washer, when the positive and negative connecting electric slices are electrified, the electroshock phenomenon created by the finger inadvertently touching the electric pole is prevented. Only when the lamp cap first enters the lamp base to be positioned correctly, and each electric pole can have an opportunity to be conducted with the positive and negative connecting electric slices, because the utility model is provided with more reasonable layout, more reliable working, extra strong security, few elements, easy assemble process and low production cost, the utility model can be rapidly popularized and be widely used in the illumination of the wide countryside and city.

Description

Two-purpose anti-electroshock lamp base for screw and bayonet socket

The utility model relates to a kind of lamp socket, particularly spiral shell, the dual-purpose protection against electric shock lamp socket of bayonet socket.The existing patent No. is (91215869.7) spiral shell, bayonet socket dual-purpose safe lamp socket, and from its Figure of description: it is defectiveness in design, and layout is more random, and action is indistinct, part is too much in addition, and assembly difficulty is big, expends man-hour.Especially show when screw cap is screwed on, though part ₁₃Drive the negative pole power connecting sheet ₇Rise and make part ₆With its contact, but neglected part ₁₁When rising, also can make part ₈And part ₇Contact is again because of part ₁₁And part ₉Contact screw cap metal-back end face simultaneously,,,, dropped into approved product drawing in batches at present and departed from former claim already owing to the inadequate natural endowment reason so its functional reliability and fail safe are relatively poor so very easily cause short circuit.

The purpose of this utility model is by the patent No. is (91215869.7) spiral shell, the dissection of bayonet socket dual-purpose safe lamp socket and be improved to the user and provide layout more reasonable, reliable operation, high safety, parts rareness in addition, production cost is low, assembles easy spiral shell, the dual-purpose protection against electric shock lamp socket of bayonet socket, it is popularized rapidly in the domestic lighting in vast rural area and city surely and is widely used.

The utility model is characterised in that the energising bar ₁₀As spiral shell, the general positive pole energising bar of bayonet socket, energising bar ₁₄As bayonet socket negative pole energising bar, middle energising bar ₁₂Individual as screw socket negative pole energising bar.Stretching into a shell one end at each energising bar is provided with insulating pad and blocks separately stage clip the energising bar other end is stretched outside by force.Negative pole electric shock sheet ₆Double simultaneously screw socket, bayonet socket negative pole electric shock reed, negative pole connect electroplax ₅Directly connect with crossing electric reed one end, resilient electric shock reed has when middle energising bar ₁₂In last when top, is to the characteristic of a disconnected end perk.

The explanation of accompanying drawing drawing: Fig. 1 is positive full sectional view, and Fig. 2 is the left side full sectional view, and Fig. 3 is the vertical view that covers, and Fig. 4 keeps flat outside drawing.Among the above figure ₁Be the top cover of pendent lamp seat, ₂Be that positive and negative electrode connects electroplax, ₃Be brass screw, ₄Be securing member, ₅Be the negative pole current piece, ₆Be negative pole electric shock sheet, ₇Be anodal electric shock sheet, ₈Be insulation board, ₉Be long stage clip, ₁₀Be anodal energising bar, ₁₁Be short stage clip, ₁₂Be screw socket negative pole energising bar, ₁₃Be a shell, ₁₄It is bayonet socket negative pole energising bar.

The utility model is provided by following examples:

1. overall package

Three energising bars are inserted respectively separately in the shoulder hole, overlap compression spring again, press insulation board, then part _5,7,2.Be placed on exhausted plate and fix on the shell with securing member on the position separately, assemble ready after, about levelling the energising bar with each electric shock sheet contact gap, energising test later on, warehousing after passing.

2. course of action

After bayonet cap is in place, the energising bar _10.14Respectively with negative pole electric shock sheet ₆With positive pole electric shock sheet ₇Contact forms the conducting loop.When screw cap in progressively being screwed into the lamp socket process, middle energising bar ₁₂Sheet gets an electric shock negative pole earlier ₆Middle part jack-up, the energising bar _10,14Then pushed up the energising bar simultaneously inward by lamp holder metal-back end face ₁₀Just together with positive pole electric shock sheet ₇Contact, and energising bar ₁₄Because negative pole electric shock sheet ₆Upwarp significantly earlier, both can not contact, thereby form another conducting loop.

Claims (3)

1, a kind of spiral shell, the dual-purpose protection against electric shock lamp socket of bayonet socket by end cap, the seat shell, the energising bar, stage clip, connect the electroplax sheet, the electric shock sheet is formed, it is characterized in that switching on bar 10 as spiral shell, the general positive pole energising bar of bayonet socket, energising bar 14 is as bayonet socket negative pole energising bar, middle energising bar 12 is as screw socket negative pole energising bar, stretching into a shell one end at each energising bar all is provided with the insulation board that blocks stage clip energising bar the inner is disconnected with the electric shock sheet, the other end is stretched by force outside, negative pole electric shock sheet 6 double as screw sockets, bayonet socket negative pole electric shock sheet.

2,, in described spiral shell, the dual-purpose protection against electric shock lamp socket of bayonet socket, it is characterized in that the bar of switching on according to claim 1 _10,12,14All are solid metal.

3,, in described spiral shell, the dual-purpose protection against electric shock lamp socket of bayonet socket, it is characterized in that insulation board, connect electroplax, current piece, electric shock sheet all link to each other with the seat shell by securing member according to claim 1.
