Description

Socket lamp holder and bulb

The utility model relates to lamp holder and bulb, especially a kind of Socket lamp holder and bulb.

Traditional incandescent lamp has screw socket and two kinds of patterns of bayonet socket usually.When bayonet type uses, owing in the hollow copper post spring is arranged in the bayonet cap, install not get on when not exerting oneself, reverse glass envelope in the time of firmly and easily get loose, bulb is scrapped, and the interior hollow copper post of tin drive lamp holder of taking when reversing on the bulb rotates together, the outer one deck bakelite of copper post is broken, cause lamp holder to scrap, when screw type uses, the rotation bulb easily makes bulb get loose, and causes loose contact when not exerting oneself easily.Aspect wiring, need screw off bonnet during wiring, very inconvenience, two other terminal screw leans on nearerly, easily cause short circuit hidden danger,, often can only push down the part copper wire because stranded copper wire easily scatters, easily copper wire is broken in the time of firmly, when not exerting oneself, easily get loose and cause loose contact.

The purpose of this utility model just provides a kind of easy for installation, quick, safe and reliable Socket lamp holder and bulb.

The purpose of this utility model is realized by following technical scheme:

Socket lamp holder and bulb divide lamp holder and bulb two parts.Lamp holder is made of body, binding post etc., binding post is located in the body cylindrical cavity, be threaded with body, have cavity in the careful end of terminals, the butt end outside of binding post is provided with screw thread, its binding post by attachment cap and another hollow links together, and lead passes the hollow bulb of binding post, by attachment cap it is squeezed between two binding posts.Lock lid, lock, back lock lid before also being provided with on the body, three's interlock is with spring on the cylinder of preceding lock lid, cylinder can insert in the groove on the body, by with hand by and the active force of spring, lock can reciprocating motion in the lock groove.The plug-in type bulb is to change two lampposts into taking tin on the common bulb, and lamppost can insert in the cavity of the careful end of terminals, is fixed by the lock on the body.

Socket lamp holder of the present utility model and bulb are when installing bulb, lock lid before only need pressing, two lampposts of bulb are inserted into terminals in the body in thin end cavity, lock lid before unclamping, active force lock by spring just can be fixed bulb, not only hang safe and reliablely, and contact is good, has conveniently, safe, reliable, long-lived characteristics.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A cut-away view among Fig. 1.

Socket lamp holder of the present utility model and bulb divide lamp holder and bulb two parts.Bulb is to change two lampposts into taking tin on the common bulb, and bulb is made of glass envelope 9, iron sheet shell 10, lamppost 11, and lamppost 11 is welded on the iron sheet shell 10, and lamppost 11 is provided with groove 12.Lamp holder is made of body 1, binding post 2 etc., binding post 2 is located in body 1 cylindrical cavity 5, be threaded with body 1, have cavity 6 in the binding post 2 thin ends, the butt end outside of binding post 2 is provided with screw thread, it can link together with the binding post 3 of another hollow by attachment cap 4, attachment cap 4 is threaded with binding post 2 butt ends, have cavity 20 in the binding post 3, lead passes the cavity 20 of binding post 3, by attachment cap 4 it is squeezed between binding post 2 and the binding post 3.Lock lid 13 before also being provided with on the body 1, lock 14, back lock lid 19, three's interlock, lock 14 moves in lock groove 7, be with spring 17 on the cylinder 18 of preceding lock lid 13, cylinder 18 can insert in the groove 8 of body 1, by press the active force that reaches spring with hand, lock 14 can reciprocating motion in lock groove 7, have the lock groove 15 of semicircle on the lock 14, also have on the body 1 etc. through semicircle groove 16, the motion of lock 14 can make lock groove 15 and groove 16 concentric, at this moment, the lamppost 11 on the bulb can insert in lock groove 15 and the groove 16, and lamppost 11 is fixed on the body 1 by lock 14.

The use of Socket lamp holder and bulb is passed the cavity 20 of binding post 3 with lead, attachment cap 4 is screwed in the butt end of binding post 2 again, and lead just can be squeezed between two binding posts.When bulb is installed, press preceding lock lid 13 with hand, the lamppost on the bulb 11 is inserted in the cavity 6 of binding posts 2 thin ends, after loosing one's grip, lamppost 11 is fixed on the body 1 by lock 14, and the groove 12 on the lamppost 11 may be stuck on the lock 14.
