Abstract

The utility model relates to a two-purpose lamp holder, which is jointly used by a bulb with bayonet cap and a screw socket bulb. The utility model is an improved type on the basis of a screw lamp holder, two bayonets are arranged on a screw thread inner sleeve (6), two electrodes are arranged in the lamp holder, one of the two electrodes is an elastic column head type electrode (3), and the other electrode is an elastic reed type electrode (4). The utility model solves the problem that a screw lamp holder and a bayonet lamp holder have to respectively use corresponding bulbs for a long time.

Description

Dual-purpose lamp holder

The utility model relates to a kind of dual-purpose lamp holder that is used for incandescent lamp.

The Incandescence lamp holder that uses is gone up by society now, generally be divided into edison socket and bayonet cap, these two kinds of lamp holders separately use separately, edison socket is by cover in the screw thread screw base lamp to be fixed on the lamp holder, a spring chip electrode is arranged in its lamp holder, and cover constitutes another electrode in the screw thread, and this lamp holder only is applicable to screw base lamp; Bayonet cap is by a metallic sheath that has two bayonet sockets bayonet socket light to be fixed, and two elasticity column cap formula electrodes are arranged in its lamp holder, and this lamp holder can only be applicable to bayonet-type bulb.When using incandescent lamp, be restricted so just for people, very inconvenient.Once saw a kind of dual-purpose lamp holder on the market, and be actually bayonet socket and two kinds of lamp holders of screw-socket are linked together simply, during use, bayonet socket and two kinds of bulbs of screw-socket were received the bayonet cap place and the edison socket place of this lamp holder respectively.Although it is more convenient that this dual-purpose lamp holder uses, not attractive in appearance, and cause waste of material.

The purpose of this utility model provides a kind of dual-purpose lamp holder easy to use, both can connect bayonet-type bulb, also can connect screw base lamp.

In order to reach above purpose, two electrodes that overlap roof in cover and the screw thread in the shell that dual-purpose lamp holder of the present utility model is covered, insulated by the lamp holder of insulation, the screw thread that outer casing inner wall is made of metal are formed, be enclosed near electrode place radius micro little in its screw thread, putting two in the screw thread is the bayonet socket of symmetry axis with cover axis in the screw thread, in two electrodes, one is elasticity column cap formula electrode, and another is an elastic spring formula electrode.

Adopt the lamp holder behind this spline structure, when buying bulb, need not to consider again bayonet socket and screw-socket, bring convenience for people's life, in addition, also saved raw material.

Below in conjunction with accompanying drawing embodiment of the present utility model being done one describes in detail.

Fig. 1 is the front view of the dual-purpose lamp holder of the utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

From Fig. 1 to Fig. 3 as can be seen, dual-purpose lamp holder of the present utility model, it is the modified model of existing edison socket, be to overlap 6 in the shells 1 of lamp holder lid 7 insulation of making by insulating material and the screw thread that the metallic conductor in the shell 1 is made, and two electrodes at cover 6 tops are formed in the cap screw thread, cover 6 is fixed in the shell 1 in the screw thread, two electrodes are fixed on the top of cover 6 in the screw thread by insulating material, cover 6 is little near electrode place radius micro in the screw thread, in order to allow bayonet-type bulb and the screw base lamp can a shared top, in screw thread, open two bayonet sockets 5 symmetrically on the cover 6, two bayonet sockets 5 overlap in the little screw thread of radius micro distinguishes level to two lateral bendings on 6, bayonet-type bulb promptly may be stuck on the lamp holder by two bayonet sockets 5 like this, in order to allow bulb be stuck on the lamp holder, two electrodes of bayonet-type bulb contacts with two electrodes in the lamp holder, and two bayonet sockets 5 should be symmetry axis to overlap 6 axis in the screw thread, two terminal lines of bayonet socket 5 horizontal curvatures, preferably vertically divide two electrodes, 3 equally, 4 pin deck spacings.

In addition, because the distribution of electrodes situation of screw base lamp is: electrode is in its metal threaded top central authorities, another electrode promptly is metal threaded, and two electrodes of bayonet-type bulb are on bulb eck top, in order to allow the electrode 3 of dual-purpose lamp holder, 4 are applicable to bayonet socket and screw base lamp, two electrodes can be designed to elasticity column cap formula electrode 3 and elastic spring formula electrode 4 respectively, the reed of elastic spring formula electrode 4 extends to column cap formula electrode 3, and the not end of reed will be crossed two electrodes 3 slightly, the mid point of 4 pin deck spacings, after screw base lamp is fixed like this, the electrode of bulb top central authorities can contact with the reed of elastic spring formula electrode 4, and the metal threaded of bulb then contacts with the elasticity column cap formula electrode 3 of lamp holder.For bayonet-type bulb, after bulb was fixed on the lamp holder by bayonet socket 5, elasticity column cap formula electrode 3 and elastic spring formula electrode 4 just in time contacted with two electrodes of bulb.Elasticity column cap formula electrode 3 and elastic spring formula electrode 4 are to be fixed on the insulator of lamp shell 1 inner top by screw 8, and two wires of power supply are connected on respectively on two screws 8 by the line hole 9 on the lamp holder enclosing cover 7 and communicate with lamp holder two electrodes 3,4.

Claims (3)

1, a kind of dual-purpose lamp holder that is used for incandescent lamp bulb, it is by the lamp holder lid (7) of insulation, the shell (1) of insulation, and interior cover of screw thread (6) and interior two electrodes that overlap the top of screw thread that shell (1) inwall is made of metal are formed, it is characterized in that: cover (6) is little near electrode contact place radius micro in the screw thread, there are two to be the bayonet socket (5) of symmetry axis in the screw thread on the cover (6) with cover (6) axis in the screw thread, in two electrodes, one is elasticity column cap formula electrode (3), and another is an elastic spring formula electrode (4).

2, dual-purpose lamp holder according to claim 1, it is characterized in that: bayonet socket (5) overlaps on (6) in screw thread, cover (6) axis direction extends to screw thread interior cover (6) reduced radius place (2) difference level to the both sides bending in the screw thread along being parallel to, and the line that two bendings are not held is vertically divided two electrode column spacings equally.

3, dual-purpose lamp holder according to claim 1 is characterized in that: the reed of elastic spring formula electrode (4) extends to elasticity column cap formula electrode (3), and its reed is not held the mid point of crossing two electrode column spacings slightly.
