Description

Two-way lampholder for screw base and bayonet base

The utility model relates to light fixture, a kind of specifically light bulb holder.

Now, the lighting that people use, two kinds of bulbs that screw thread and straight cutting are arranged, associated have two kinds of lamp sockets: a kind of is threaded socket, it forms the two poles of the earth by the contact and the neck ring screw thread of socket central authorities, when center contact, the screw thread of screw thread bulb contacts with center contact, the neck ring screw thread of socket, electrified light emitting then; Another kind is a plug adapter, and it is connected with two contacts on the bulb by two contacts on the lamp socket, the energising illumination.The straight cutting bulb only is used for plug adapter, and screw lamp holder is only joined the use of screw thread bulb, and two kinds of lamp sockets can not be common to screw thread and straight cutting bulb, in use bring inconvenience then for people, and a thing can not be used more, also can cause some economic losses; Simultaneously to production and supply, can cause also that supply falls short of demand or the phenomenon of overstocking and sluggish sale, turnover has certain influence to production capital.

In order to overcome the problem of above-mentioned existence, the purpose of this utility model designs a kind of Two-purpose lampstand that can make shared screw socket of screw thread bulb and straight cutting bulb and socket be mutually one.

The purpose of this utility model is achieved in that it is made up of housing, lamp socket and protective case.Lamp socket is made by the one socket copper neck ring of setting-in on the bakelite piece.Four contacts are arranged on lamp socket, three in line copper post contacts are arranged on the bakelite piece, on its periphery, also have screw thread; And socket copper neck ring is the 4th contact, and it is to link to each other with a bronze medal post contact through copper sheet to form; On socket copper neck ring, have the L shaped socket of symmetry.The inside and outside wall of protective case one end is provided with screw thread, is shaped on the ripple helicla flute on its inwall stage casing, has vertical socket guiding straight trough of symmetry on the ripple helicla flute, has L shaped socket on same straight line on this straight trough and the socket copper neck ring.Protective case and bakelite piece spiral are integral.Three copper post contacts on the bakelite piece, two of both sides copper post contacts wherein, for connecing the usefulness of straight cutting bulb two contacts, and middle copper post contact and socket copper neck ring are two contacts that are used for the connecting thread bulb.

The utility model is with used screw socket and two kinds of lamp sockets of socket, reconfigures the screw socket, the socket Two-purpose lampstand that form cleverly, and screw thread bulb and straight cutting bulb all can use, and it meets the international standard of existing screw thread bulb and straight cutting bulb.

In addition, on the ripple helicla flute on the protective case inwall, need not out vertical socket guiding straight trough, only need at place, ripple spiral fluted bottom, if a spiral deep trouth that two pins of socket bulb can be revolved, then the straight cutting bulb can be directly along ripple helicla flute and the precession of spiral deep trouth, and straight cutting is gone into L shaped socket, the contact of bulb and the contact of lamp socket are joined, and this is another program of screw socket, socket Two-purpose lampstand.

The utility model compared with prior art, its advantage: the utlity model has existing two kinds of functions with screw socket and plug adapter, easy to use; Reduce by a kind in the production, can produce in a large number; Product overloading and out of stock phenomenon can not take place in the single convenience of kind of supply; It meets international standard, can be general in the whole world.

The utility model can also obtain further instruction from following drawings and Examples:

The drawing explanation:

The 1-housing, 2-bakelite piece, 3-spring, 4,5,6-contact pillar, 7,13,14-copper post contact, 8, the 23-protective case, 9-socket copper neck ring, 10-L shape socket, 11-ripple helicla flute, 12-socket guiding straight trough, the 15-copper sheet, 16, the 17-screw, 18,19, the 20-jack, 21,22-power supply pressing plate, 24-spiral deep trouth.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:

The utility model is a kind of screw socket, socket Two-purpose lampstand, is made up of housing 1, lamp socket and protective case 8.Lamp socket is made by being embedded with socket copper neck ring 9 on the bakelite piece 2, establishes jack 20,19,18 in upright arrangement and screw 16,17 on bakelite piece 2, and its periphery is provided with screw thread; 20,19,18 li of jacks, contact pillar 4,5,6 is housed respectively, and copper post contact 7,13,14 and spring 3 are sub-packed in the contact pillar 4,5,6; Contact pillar 5,6 links to each other with power supply pressing plate 22, and contact pillar 4 is connected with power supply pressing plate 21, and power supply pressing plate 21 and 22 is packed on the screw 16 and 17 of bakelite piece 2 with screw respectively; Copper sheet 15 fuses contact pillar 4 and socket copper neck ring 9; To the neck ring middle wall, have symmetrical L shaped socket 10 at socket copper neck ring 9 one ends.Protective case 8 is a cylindrical shape, on the inside and outside wall of one end, be provided with screw thread, other end port flare, be provided with ripple helicla flute 11 at the middle part of cylinder inner wall, and having symmetrical vertical socket guiding straight trough 12 on the ripple helicla flute 11, the L shaped socket on this guiding straight trough 12 and socket copper neck ring 9 is on same straight line; Lamp socket and protective case 8, protective case 8 and housing 1 fuse by the screw thread spiral shell of going up separately each other, and this is embodiment 1.

Embodiment 2: the present embodiment difference from Example 1 is that protective case 23 and protective case 8 structurally have any different slightly; On the ripple helicla flute 11 of protective case 23 inwalls, do not have vertical socket guiding straight trough 12, but locate in the bottom of this ripple helicla flute 11, an if spiral deep trouth 24, the size of this spiral deep trouth 24, the two pin precessions that can make the straight cutting bulb are by getting final product, when two pins of straight cutting bulb carry over ripple helicla flute 11 and spiral deep trouth 24 screw in pass through after, then two pins of straight cutting bulb just insert in the socket guiding straight trough 12, tighten again, this moment bulb two contacts and lamp socket on two corresponding contacts join electrified light emitting; Meanwhile, the copper post contact 13 in the middle of on the lamp socket also falls within on the bulb on the plane between two contacts, because of this plane is an insulating material, so can not form short circuit phenomenon.Present embodiment is that the protective case 8 with embodiment 1 changes protective case 23 into, other all and embodiment 1 identical.

Use operation: 1) the screw thread bulb is along the ripple helicla flute precession of protective case, and after screw thread bulb center contact and screw lamp holder center contact were joined, then the screw thread on the screw thread bulb tightly was nested together with socket copper neck ring internal perisporium, and both have formed path, and promptly lamp is bright.2) straight cutting bulb two pins enter L shaped socket on earth along ripple spiral fluted socket guiding straight trough on the protective case, change an angle again, with the socket copper neck ring clamping of straight cutting bulb and lamp socket, make two pairs of contact mutual connection energisings.3) after straight cutting bulb two pins pass through along the ripple helicla flute on the protective case and the precession of spiral deep trouth, change an angle again, two pairs of contacts are joined get final product electrified light emitting with regard to straight cutting to L shaped socket bottom.
