Abstract
The utility model discloses a kind of novel lamp base, comprise insulating body, insulating body is provided with installation cavity, the bottom is fixed with two conducting metal pin, be provided with the through hole that makes things convenient for the lamp body electrode connecting line to connect in the conducting metal pin, the insulating body bottom interior surface between two conducting metal pin is provided with the back-up block of projection; Therefore electrical distance between two conducting metal pin, the fuse length in the electrode connecting line have obtained prolonging effectively, and creepage phenomenon is difficult to produce; Even indivedual light fixtures produce creepage phenomenon, fuse also can fuse timely and effectively, prevents that bulb from producing the phenomenon of blast.
Description
Technical field
The utility model relates to a kind of lamp socket, particularly a kind of novel lamp base that can effectively prevent creepage phenomenon generation, safety.
Background technology
A kind of lamp socket is arranged, comprise insulating body, insulating body is provided with installation cavity, the bottom riveted joint has two conducting metal pin, is provided with the through hole that makes things convenient for the lamp body electrode connecting line to connect in the conducting metal pin.Yet; insulating body bottom between two conducting metal pin is almost the plane; therefore cause electrical distance, the fuse length in the electrode connecting line between two conducting metal pin relatively short; produce creepage phenomenon between the electrode and fuse does not have effective protection; gas superheat in the lamp body expands and explodes, and has certain potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can effectively prevent the generation of creepage phenomenon and the novel lamp base of safety.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel lamp base, comprise insulating body, insulating body is provided with installation cavity, the bottom is fixed with two conducting metal pin, be provided with through hole in the conducting metal pin, it is characterized in that: the insulating body bottom interior surface between two conducting metal pin is provided with the back-up block of projection.
Wherein, described back-up block is located in the hole.
Advance an improvement as of the present utility model, the both sides of described back-up block, the outer rim in hole are provided with the block of projection, make things convenient for the installation of bulb with this.
Advance an improvement as of the present utility model, be provided with the louvre that is communicated with the insulating body bottom outer surface in the described stop body, the heat that light source produces can be lost to the external world by louvre.
The beneficial effects of the utility model are: the back-up block that is provided with projection owing to the insulating body bottom interior surface between two conducting metal pin, therefore electrical distance between two conducting metal pin, the fuse length in the electrode connecting line have obtained prolonging effectively, and creepage phenomenon is difficult to produce; When electric current increased suddenly, fuse can fuse timely and effectively, prevented the phenomenon that causes the bulb blast because of creepage.

Embodiment
Referring to figs. 1 through Fig. 5, a kind of novel lamp base comprises insulating body 1, and insulating body 1 is provided with installation cavity 2, the bottom is fixed with two conducting metal pin 3, insulating body 1 bottom interior surface that is provided with in the conducting metal pin 3 between 4, two conducting metal pin 3 of through hole is provided with protruding back-up block 5; Therefore electrical distance between two conducting metal pin 3,9 length of the fuse in the electrode connecting line have obtained effective prolongation, thereby have prevented the generation of creepage phenomenon effectively; When electric current increased suddenly, fuse 9 can fuse timely and effectively, prevented the phenomenon that causes the bulb blast because of creepage.Wherein, described back-up block 5 is located in the hole 6, and back-up block 5 is divided into two independent parts separately to hole 6, and conducting metal pin 3 lays respectively in above-mentioned two parts hole 6 with the junction of insulating body 1 bottom interior surface.
Bulb is installed on the lamp socket for convenience, the both sides of described back-up block 5, hole 6 outer rims are provided with the block 7 of projection, the center line connecting direction and the conducting metal pin 3 of block 7 positions are orthogonal, the height of block 7 projectioies is greater than back-up block 5, as long as the two poles of the earth connecting line of bulb is striden across back-up block 5, the two poles of the earth connecting line just can pass the through hole 4 of conducting metal pin 3 easily, and just can be welded on electrode connecting line on the conducting metal pin 3 easily this moment.
In order further to improve the utility model fail safe in use, be provided with the louvre 8 that is communicated with insulating body 1 bottom outer surface in described block 7 bodies, the heat that light source produces can be lost to the external world by louvre, from preventing the phenomenon that gas superheat expands and generation is exploded in the lamp body to the full extent.
With reference to Fig. 6, Fig. 7, as the another kind of embodiment of the utility model, the back-up block 5 of 1 bottom interior surface of the insulating body between two conducting metal pin 3 design projection simply.
Certainly, the utility model is not limited to above-mentioned execution mode, is equal to the utility model or becomes bad technical scheme to belong to protection range of the present utility model.
