[specific embodiment]
With reference to the accompanying drawing and specific embodiment is further described the utility model:
As shown in Figure 1-Figure 3, the onboard charger of the utility model refers to conventionally by automobile storage battery (car 12V, card
Vehicle 24V) power supply onboard charger.Including shell 10, charging circuit board 20, USB interface 30 and connecting terminal 40, USB is connect
Mouth 30 and connecting terminal 40 are electrically connected with charging circuit board 20 respectively, and connecting terminal 40 is used to connect with the cigar lighter of automobile,
Connecting terminal 40 includes cathode contact 41 and cathode elastic slice 42, and cathode contact 41 passes through a spring 43 and charging circuit board 20
Anode interface electrical connection, cathode elastic slice 42 are electrically connected with the cathode interface of charging circuit board 20, and shell 10 is far from USB interface 30
One end is equipped with the through-hole 11 stretched out for cathode contact 41.The general configuration of onboard charger and its circuit structure are all this field
The prior art known to technical staff, details are not described herein.Charging circuit board 20 is equipped with charge controlling chip 21, in this implementation
Chip is depressured using GS92D2 type in example, to be depressured to automobile storage battery power supply.Cathode elastic slice 42 includes flexible connection piece 44
And the cathode contact 45 set on 44 both ends of flexible connection piece, flexible connection piece 44 have elasticity, the outer peripheral surface of shell 10 is equipped with
Bayonet 12 compatible with cathode contact 45.Bayonet 12 contacts with cigar lighter on automobile for the exposing of cathode elastic slice 42 and connects confession
Electricity.Wherein 43 steel construction piece of spring that flexible connection piece 44 and cathode contact 45 are integrally formed, 44 bending of flexible connection piece
" Jiong " type is surrounded, specific size is adapted with the internal diameter of shell 10, and cathode contact 45 is in the rectangle protruded outward, can be by elasticity
The both ends punching press deformation of connection sheet 44 is formed, without the connection process such as welding, convenient for production and stable structure.Flexible connection piece 44
Flexible deformation can occur to be packed into shell 10, flexible connection piece 44, which provides restoring force, makes cathode contact 45 at two be caught in shell 10
Bayonet 12 in, while keeping cathode elastic slice 42 fixed.Charging detection chip 22 is additionally provided on charging circuit board 20, close
One end of USB interface 30 is equipped with status indicator lamp 50, the outer peripheral surface of the covering shell 10 in a ring of status indicator lamp 50, in this implementation
Using the processing chip detection of WN2011 type and state of a control indicator light 50 in example.Status indicator lamp 50 and charging detection chip
22 are electrically connected the charged state to show electronic equipment.So that electronic equipment is not necessarily to check that electronic equipment just may know that after being full of
Charged state prevents electronic equipment from overcharging, easy to use and effective guarantee traffic safety.
The foregoing is merely this patent preferred embodiments, not limit this patent range, all using specification and attached
Equivalent structure or equivalent flow shift made by figure content is directly or indirectly used in other relevant technical fields, belongs to
The scope of this patent.
