Abstract
The utility model relates to an adapter of a cigarette lighter. The adapter includes an adapter body, a positive electrode and two negative electrodes. The adapter body is in a cylinder shape. The positive electrode is arranged on a front end face of the adapter body. The negative electrodes are made of elastic material. The two negative electrodes are disposed symmetrically on an external end face of the adapter body. In the utility model, the positive electrode is arranged on a front end face of the adapter body, the two negative electrodes made of elastic material are disposed symmetrically on an external end face of the adapter body. Thus, the adapter has a simple structure, a small volume and convenient usage. Moreover, a fuse is arranged in the adapter. The power is automatically cut off when current is excessive. Thus, a good protection function is realized and the usage is safer and more reliable.
Description
Technical field
The utility model relates to a kind of adapter that is used for cigar lighter that comprises body, positive electrode and negative electrode.
Background technology
Along with rapid development of automobile industry, the people who has private car is more and more, people travel outdoors or handle affairs and need drive automobile for a long time, small electric apparatus in automobile uses long-time use may just not have electricity, need charge to it, and generally all be to charge to electrical equipment now by cigar lighter, this just also needs with an adapter cigar lighter and electrical equipment to be coupled together, occurred a kind of adapter on the market, comprised a two-part housing, piece housing and back piece housing before comprising; One positive electrode contact element is installed on the top of the leading portion of this housing, to electrically contact the positive electrode of this cigarette lighter socket; One elastic contact element is surrounded on the front and rear sections housing junction of this housing, electrically contacting the negative electrode of this cigarette lighter socket, and this adapter structure complexity, volume is big, uses very inconvenient.
The utility model content
The purpose of this utility model is at the problems referred to above, and a kind of adapter of simple in structure, cigar lighter that volume is little is provided to society.
The technical solution of the utility model is: the adapter that designs a kind of cigar lighter, comprise body, positive electrode and two negative electrodes, described body is cylindrical shape, described positive electrode is arranged on the front end face of body, described negative electrode is that elastomeric material is made, and described two negative electrodes are symmetricly set on the outer face of body.
As to improvement of the present utility model, in described body, be provided with fuse near front end face, described fuse is connected with intrinsic positive electrode by spring.
The utility model is owing to the front end face at body is provided with positive electrode; the outer face is provided with the negative electrode that the employing elastomeric material of two symmetries is made; such adapter structure is just very simple; volume is also littler; use more conveniently, and also be provided with fuse in the body, when electric current is excessive, can cut off the power supply automatically; play the protective effect of arriving very much, use safety and reliability.
Description of drawings
Fig. 1 is the perspective view of a kind of embodiment of the utility model;
Fig. 2 is the internal structure schematic diagram of Fig. 1.
Embodiment
See also Fig. 1, Fig. 1 be a kind of adapter of cigar lighter with disclosing, comprise body 1, positive electrode 2 and two negative electrodes 3, described body 1 is cylindrical shape, described positive electrode 2 is arranged on the front end face 11 of body 1, directly positive electrode 2 is connected with the positive pole contact of electrical equipment during use, both are seated, guarantee that connection is reliable and stable, described negative electrode 3 is that elastomeric material is made, so long-time use also is not easy to damage, life cycle is long, and described two negative electrodes 3 are symmetricly set on the outer face of body 1, and the situation according to electrical equipment during use is decided, if electrical equipment has only a negative pole, just only need be connected the negative pole contact of any one negative electrode 3 and electrical equipment wherein; When electrical equipment has two negative poles, just two negative electrodes 3 are connected with two negative poles contacts of electrical equipment simultaneously, the utility model only need be provided with positive electrode 2 and negative electrode 3 on body just can satisfy and used, and overall structure is simple, and volume is also very little, and is easy to use.
See also Fig. 2; Fig. 2 is an internal structure schematic diagram of the present utility model; in described body 1, be provided with fuse 4 as can be seen from FIG. near front end face 11; described fuse 4 is connected by the end 12 of the interior positive electrode 2 of spring 5 and body 1; when very big electric current passes through; if there is not fuse 4; comprise that adapter and electrical equipment all may burn out; and add a fuse 4; by electric current when excessive, fuse 4 just can cut off circuit, can be good at protecting adapter and electrical equipment; can be good at a fuse 4 by spring 5 and be fixed in the body 1, guarantee the stability of using.
