Description
Technical field
This utility model is related to a kind of charger, more precisely, is related to a kind of onboard charger.
Background technology
Onboard charger is the accessory that car owner's vehicle power charges for digital product whenever and wherever possible for convenience, uses
When, only one end of onboard charger need to be inserted in the jack of automobile cigarette lighter, connecting data wire can charge to digital product.
The plug of onboard charger all uses the structure design that shell fragment adds contact mostly on the market at present, that is, charging
One cathode contact with coil tension spring of the tip designs of device, inserts the front end setting two panels arc of cigarette lighter socket in charger
Shell fragment, during use, with the positive contact of cigar lighter, arc spring lamination is stuck in inside cigarette lighter socket cathode contact, makes as negative pole
With, because cathode contact and cigarette lighter hole positive contact are point contact type, often loose contact, lead to electric conductivity poor, often need
Multiple plug onboard charger to adjust, lead to charger abrasion or damage, reduce service life.
Utility model content
This utility model is in order to solve problems of the prior art, there is provided a kind of onboard charger.
In order to realize above-mentioned purpose, the technical solution of the utility model is：
A kind of onboard charger includes housing, and the centre position of described housing forward end is provided with negative pole shell fragment, described negative pole bullet
Piece is connected with the negative pole of the circuit board being located in housing cavity, also includes the positive contact head located at housing tip, described just
The outer end of pole contact head is additionally provided with insulator cap, is additionally provided with spring, one end of spring in the inner chamber of described positive contact head
Positive contact head for being connected with automobile cigarette lighter is connected, and the other end of spring is connected with the positive pole of circuit board, also includes setting
It is placed in the USB output interface of housing rear end, described output interface can be a USB interface or multiple USB output interface, also includes
End cap.
Preferably, described positive contact head is set to the circular platform structure protruded.
Preferably, described positive contact head may also be configured to polygonal structure.
Preferably, described positive contact head may also be configured to spherical nose structure.
Preferably, the inner chamber of described positive contact head and the contact surface of spring are planar structure.
Due to spring larger with the contact area of positive contact head it is ensured that the sensitivity that contacts, also because contact area is big
Increased heat sinking function, thus improve the service life of onboard charger.Because positive contact head is set to the circle of protrusion
Platform structure, solves existing onboard charger due to being using the contact of top cathode contact formula, because contact area is little, leads to
Loose contact, and multiple plug adjustment easily makes shell fragment follow the string using rear, thus lead to damage reducing asking of service life
Topic.
Brief description
Fig. 1 shows the schematic diagram of the spherical nose structure of this utility model charger.
Fig. 2 shows the generalized section of the circular platform structure of the protrusion of this utility model charger.
Fig. 3 shows the schematic appearance of the spherical nose structure of this utility model charger.
Fig. 4 shows the schematic appearance of the circular platform structure of the protrusion of this utility model charger
Fig. 5 shows the schematic appearance of the polygonal structure of this utility model charger.
Specific embodiment
In order that the technical problem that this utility model solves, the technical scheme of employing, the technique effect of acquirement it can be readily appreciated that
With reference to specific accompanying drawing, specific embodiment of the present utility model is described further.
With reference to Fig. 1, Fig. 2, Fig. 4, a kind of onboard charger includes housing 4, and the centre position of described housing 4 front end is provided with negative
Pole shell fragment 3, described negative pole shell fragment 3 is connected with the negative pole of the circuit board 6 being located in housing cavity, also includes located at housing 4 top
Positive contact head 1, described positive contact head 1 be set to protrude circular platform structure, in the outer end of described positive contact head 1
It is additionally provided with insulator cap 2, the inner chamber of described positive contact head 1 is additionally provided with spring 5, one end of spring 5 is used for and automobile
The positive contact head 1 that cigar lighter connects connects, and the other end of spring 5 is connected with the positive pole of circuit board 6, also includes being arranged at housing
The USB output interface 7 of rear end, described output interface 7 can be a USB interface or multiple USB output interface, also includes end cap 8.
In another embodiment of the present utility model, described positive contact head 1 employs polygonal structure, ginseng
Examine Fig. 5.
In another embodiment of the present utility model, described positive contact head 1 employs spherical nose structure,
With reference to Fig. 3.
Described onboard charger, when using, positive contact head is stuck in and lights a cigarette with the positive contact of cigar lighter, negative pole shell fragment
Inside device jack, use as negative pole, the form fit of cigar lighter in the shape of vehicle-mounted plug and automobile, will vehicle-mounted insert during use
Head is inserted in the cigar lighter of automobile, realizes the output of automobile power source, this belongs to the common knowledge of those skilled in the art, here
No longer illustrate.
Spring is larger with the contact area of positive contact head to ensure that the sensitivity contacting, also because contact area increased greatly
Heat sinking function, thus improve the service life of onboard charger.Because the circular platform that positive contact head is set to protrude is tied
Structure, solves existing onboard charger due to being using the contact of top cathode contact formula, because contact area is little, leads to contact not
Good, and multiple plug adjustment easily makes shell fragment follow the string using rear, thus leading to damage the problem reducing service life, thus
Increased reliability and the service life of onboard charger.
This utility model has passed through preferred embodiment to have carried out detailed explanation.However, by studying carefully above,
Change to each embodiment and increase are obvious for those of ordinary skill in the art.The intention of applicant
It is that all these changes and increases all to fall in this utility model scope of the claimed protection.
