Abstract

The utility model discloses a vehicle-mounted charger. The vehicle-mounted charger comprises a housing, and a positive pole input end arranged at a bottom end of the housing, negative pole input ends arranged at a side edge of the housing, a PCB arranged in the interior of the housing and a USB joint arranged at a port of the housing, wherein the positive input end, the negative input ends and the USB joint are connected with the PCB simultaneously. The housing comprises a unit body and a cover body which are integrally molded and are in clamping fit with each other. When two vehicle-mounted chargers are adopted to supply power, two negative pole ends can exert effect, so poor contact of negative poles in utilization process can be avoided; the housing of the vehicle-mounted charger is composed of the unit body and the cover body, which enables convenient assembly; the negative poles and the printed circuit board are design into a clamping piece, and the clamping piece is of convenience in assembly and can be effectively locked on the unit body; and the unit body can be prevented form cracking, thereby preventing the clamping piece from dropping.

Description

A kind of onboard charger

Technical field

The utility model relates to a kind of charger, particularly a kind of onboard charger.

Background technology

Charger is commonly referred to as a kind of equipment that alternating current is converted to low-voltage DC, charger is of many uses in every field, particularly be widely used in mobile phone, the common electrical equipment of camera at sphere of life, there is a kind of onboard charger that is applied in the car the inside to be with a wide range of applications, but existing onboard charger negative electrode head has two, only have a negative electrode head to work during power supply, easily produce negative pole loose contact phenomenon in the use procedure; Existing onboard charger shell has upper lower casing, and closes shell between negative electrode head, and shell easily appears in use procedure to split, the negative electrode head obscission, so we must be improved present situation.

The utility model content

The technical problems to be solved in the utility model overcomes defects, and a kind of novel on-vehicle charger is provided.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of onboard charger, comprise shell, and be arranged at the electrode input end of shell bottom, and be arranged at negative input on the shell side, and be arranged at the PCB circuit board of enclosure, and be arranged on the USB joint of outer cover port, described electrode input end, negative input and USB joint be the connection PCB circuit board simultaneously, described shell comprises body and lid, described body and lid all are one-body molded and body and lid hold cooperation, described USB joint is arranged on the lid port and is connected in the PCB circuit board of internal body, described body bilateral symmetry is provided with two negative pole fixing holes, described body bottom is provided with an anodal fixing hole, described two negative inputs are two contractile arc-shaped spring pieces and are fixed in PCB circuit board both sides, two contractile arc-shaped spring pieces of PCB circuit board and both sides form a fastener, electrode input end is fixed in PCB circuit board lower end, described fastener can directly insert in the body from the body openend, two snap-in structures of the interior formation of negative pole fixing hole that contractile spring leaf enters the body both sides.

Further, described electrode input end is the elasticity power connecting column.

Further, described body and lid are plastic material.

Further, described body and lid are the five metals material.

The beneficial effects of the utility model are: two onboard chargers are arranged, and two negative electrode heads can work during power supply, and negative pole loose contact phenomenon can not appear in use procedure; The onboard charger shell is comprised of body and lid, assembling easily, negative pole becomes a kind of fastener with board design, described snap-in structure is easy to assembly, can effectively fastener be locked on the body, and prevent the body fastener that comes off that splits.
