Abstract
The utility model discloses a kind of charger, comprise circuit board, comprise as negative pole and have the metal shell of cavity volume, described circuit board is arranged in described cavity volume, is provided with positive contact head in the termination of metal shell by insulation assembly; Described positive contact head is connected with the electrode input end of circuit board, and described metal shell is connected with the negative input of circuit board.Charger of the present utility model, is charged to mobile terminal by power/data transmission line.Use metal shell and coordinate the metal positive-pole contact head of positive pole fastener spring piece in cigar lighter to reach conductive radiator, electromagnetism interference is strong, durable, solves the problem of the loose contact that vehicle travels process moderately gusty air produces.
Description
Technical field
The utility model relates to a kind of charger, more precisely, relates to a kind of ignition head charger.
Background technology
Existing vehicle charger, comprises charger body, output port of power source, positive electrode, negative electrode, spring; Described output port of power source is arranged on charger body one end, and positive electrode is arranged on charger body one end, and negative electrode is embedded is arranged on charger body side, and by spring supporting bottom negative electrode, spring is fixed in charger body.
The charger of said structure, electrode plates is little, easily contacts bad at vehicle travels process moderately gusty air, thus logarithmic code product produces harmful effect.And the charger of this structure is unfavorable for the shortcomings such as heat conduction, shell is yielding, anti-electromagnetic interference capability is little; Positive contact point is narrow and small is unfavorable for that current delivery can have a strong impact on transformation efficiency and produce high temperature when oepration at full load, plastic shell can be made to be out of shape reduce cigar lighter seat positive contact sheet service life.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of charger.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of charger, comprises circuit board, comprises as negative pole and has the metal shell of cavity volume, described circuit board is arranged in described cavity volume, is provided with positive contact head in the termination of metal shell by insulation assembly; Described positive contact head is connected with the electrode input end of circuit board, and described metal shell is connected with the negative input of circuit board.
Preferably, another termination of described metal shell is provided with five metals end cap.
Charger of the present utility model, is charged to mobile terminal by power/data transmission line.Use metal shell and coordinate the metal positive-pole contact head of positive pole fastener spring piece in cigar lighter to reach conductive radiator, electromagnetism interference is strong, durable, solves the problem of the loose contact that vehicle travels process moderately gusty air produces.
Accompanying drawing explanation
Fig. 1 shows the explosive view of the utility model charger.
Detailed description of the invention
The technical problem solved to make the utility model, the technical scheme of employing, the technique effect obtained should be readily appreciated that, below in conjunction with concrete accompanying drawing, are described further detailed description of the invention of the present utility model.
With reference to figure 1, the utility model discloses a kind of charger, comprise circuit board 5, also comprise as negative pole and there is the metal shell 3 of cavity volume, described circuit board 5 is arranged in described cavity volume, is provided with positive contact head 1 in the termination of metal shell 3 by insulation assembly 2; This insulation assembly 2 can be the mount pad of a positive contact head 1, by insulation assembly 2, positive contact head 1 is arranged on the termination of metal shell 3, and positive contact head 1 is insulated with metal shell 3 phase.
Described positive contact head 1 is connected with the electrode input end of circuit board 5, and described metal shell 3 is connected with the negative input of circuit board.
This charger is inserted the cigar lighter of the vehicles, and by power/data transmission line, mobile terminal is charged.Use metal shell and coordinate the metal positive-pole contact head of positive pole fastener spring piece in cigar lighter to reach conductive radiator, electromagnetism interference is strong, durable, solves the problem of the loose contact that vehicle travels process moderately gusty air produces.
Preferably, another termination of described metal shell 3 is provided with five metals end cap 7.The output of this circuit board 5 can export with the form of USB, now, also can arrange USB female seat lid 6, certainly also can be provided with rosette 4.
The utility model is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each embodiment with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of applicant has all dropped in scope that the utility model claim protects.
