Abstract
The invention discloses an improved structure for a welding-free lamp cap. A wire penetrating hole is formed in the portion, deviating from the center position, of an insulator. The top of the wire penetrating hole is of a funnel shape and the lower portion of the wire penetrating hole is located on the periphery of a cylindrical protrusion. A guide wire is introduced from a shell of the lamp cap and penetrates through the wire penetrating hole. The end of the guide wire is bent and clamped in an inner cavity of the cylindrical protrusion, a rivet is driven into the inner cavity of the cylindrical protrusion, and therefore the end of the guide wire is fastened. According to the lamp cap of the structure, reliability in installation can be greatly improved and the phenomenon that a lamp is damaged due to looseness of the guide wire in the use process is avoided.
Description
Technical field
The present invention relates to lamp holder.
Background technology
Along with exempting from the development of welded lamp holder (insulator is plastics), its advantage of comparing with glass lamp holder is also more and more obvious.Wherein by metal rivet, replacing scolding tin is its clear superiority, but also expose shortcoming simultaneously, comes.As shown in Figure 1, routine is exempted from welded lamp holder and with rivet 4, is being compressed through the wire hole 10 in the middle of insulator 1 is rear with seal wire 3, and the impact that finished product lamp is in use expanded with heat and contract with cold occurs that seal wire becomes flexible phenomenon, causes light fixture to damage, and also to safety, hides some dangers for.
Summary of the invention
Technical problem to be solved by this invention has just been to provide a kind of welded lamp holder of exempting from, and avoids the impact that finished product lamp is in use expanded with heat and contract with cold to occur that seal wire becomes flexible phenomenon, guarantees the safety that light fixture is used.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of welded lamp holder of exempting from improves structure, comprise the lamp shell of cup-shaped and be located at the insulator of lamp shell bottom, described insulator comprises the cylindrical portion on top and is located at the round platform portion of cylindrical portion below, described cylindrical portion is along being circumferentially with annular groove, the edge of lamp shell bottom opening snaps in annular groove, bottom centre of described round platform portion is provided with circular groove, the center of described circular groove is provided with cylindrical shape protuberance, described insulator departs from center and is provided with a wire hole, wire hole top is funnel-form, wire hole bottom is positioned at cylindrical shape protuberance outer circumferential side, wire hole is introduced and passed to seal wire from lamp shell, the termination bending of seal wire also snaps in cylindrical shape protuberance inner chamber, in cylindrical shape protuberance inner chamber, hammer into rivet seal wire termination is fastening.
Preferably, the cylindrical portion end face of described insulator is provided with the fluting of circular arc at wire hole outer circumferential side, and it is large that the width of described fluting is become to middle part gradually by two ends.
Preferably, the round platform portion of described insulator is provided with limiting platform under fluting.
Preferably, described cylindrical shape protuberance bottom surface is positioned at the top of round platform portion bottom surface.
The present invention is arranged on the insulator position that keeps to the side wire hole, for improving once successful wire threading machine rate, wire hole top design funnel, when seal wire is smoothly by after wire hole, by apparatus for bending, seal wire is folded in the middle tubular protuberance endoporus of insulator, finally by rivet, seal wire is fixed firmly.Use the lamp holder of this structure can greatly improve reliability when mounted, avoid lamp in use because of getting loose of seal wire, to cause the damage of lamp.

The specific embodiment
As shown in Figures 2 to 5, a kind of welded lamp holder of exempting from improves structure, comprise the lamp shell 2 of cup-shaped and be located at the insulator 1 of lamp shell 2 bottoms, described insulator 1 comprises the cylindrical portion on top and is located at the round platform portion of cylindrical portion below, described cylindrical portion is along being circumferentially with annular groove 13, the edge of lamp shell bottom opening snaps in annular groove 13, bottom centre of described round platform portion is provided with circular groove 14, the center of described circular groove is provided with cylindrical shape protuberance 15, described insulator 1 departs from center and is provided with a wire hole 10, wire hole top is funnel-form, wire hole bottom is positioned at cylindrical shape protuberance outer circumferential side, wire hole 10 is introduced and passed to seal wire 3 from lamp shell 2, the termination bending of seal wire also snaps in cylindrical shape protuberance inner chamber, in cylindrical shape protuberance inner chamber, hammer into rivet 4 seal wire termination is fastening.Described cylindrical shape protuberance bottom surface is positioned at the top of round platform portion bottom surface.When seal wire is smoothly by after wire hole, by apparatus for bending, seal wire is folded in the middle tubular protuberance endoporus of insulator, finally by rivet, seal wire is fixed firmly.Use the lamp holder of this structure can greatly improve reliability when mounted, avoid lamp in use because of getting loose of seal wire, to cause the damage of lamp.
The cylindrical portion end face of described insulator 1 is provided with the fluting 12 of circular arc at wire hole 10 outer circumferential sides, it is large that the width of described fluting is become to middle part gradually by two ends.The use amount that this fluting 12 can be saved material on the one hand, is also convenient to produce distributing of heat simultaneously.
The round platform portion of described insulator 1 is provided with limiting platform 11 under fluting.This limiting platform is in the similar structure that cuts a jiao of round platform portion one side, this spacing shape, and after being convenient to, automatic wire feed equipment location, penetrates seal wire in limit portion wire hole smoothly.
