With machine battery all can because battery capacity is low and the normal use time of equipment cannot be met by seeming, but traveling charger goes out
Now but solves the problems, such as this well.Using accumulator as working power or the electricity consumption occasion of stand-by power supply, present charger
It is with a wide range of applications.It when using traveling charger, needs to insert the prongs in socket, if inside traveling charger
Short circuit then may be such that socket is shorted, and causes safety accident.
Utility model content
Based on this, it is necessary to provide a kind of USB traveling chargers short-circuit protection control system, including charger body, set
The wiring board being placed in charger body and the first pin and the second pin for being articulated with the charger body, described second inserts
Foot is electrically connected with the wiring board, and two protectors, first pin and the second pin are offered in the charger body
Bottom be hingedly connected to the bottom margin of two protector, wherein first pin and the second pin include mutual
The interconnecting piece and mounting portion being fixedly connected, the mounting portion are located in the protector, and the installation of first pin
Current insurance silk is installed, first pin passes through the electricity on conducting wire and first pin with second pin in portion
Fuse is flowed to be electrically connected.
In the utility model, the first pin is electrically connected by current insurance silk thereon with circuit board, when charger is short
Lu Shi, the electric current through overcurrent safety silk can increase, the fusing of current insurance silk, the internal wiring of the first pin and charger body
It disconnects, avoids the short circuit for causing socket, cause safety accident.
Wherein, the bottom surface of the first pin and the second pin is hinged with the edge of the bottom surface of protector, and the first pin and
Bottom of second bottom with the protector offsets, therefore, when the utility model is inserted on socket on the wall, charger
Front end is close on socket, can not be swung forward, and due to the blocking of the first pin or the second pin, charger also cannot be backward
It swings, ensures stability when the utility model is inserted in socket, avoid it from shaking and leak out pin and cause short circuit or leakage
Electricity.
Preferably, the mounting portion is made of insulating materials, is provided in the mounting portion and extends transversely through the mounting portion
Mounting hole, and the mounting hole vertically the protector side setting.
Mounting hole is for installing current insurance silk, after current insurance silk is packed into mounting hole, due to both sides protector
Cell wall stops so that fuse will not drop out in mounting hole.
Further, the bottom surface of the mounting portion is concordant with the bottom end of the pin.
So that the contact area bigger of the protector of the first pin and the second pin corresponding thereto, stability are more preferable
Further, the mounting hole is square hole.
The contact surface smaller of square hole and circular current insurance silk, more convenient for the handling of current insurance silk, in addition, contact
The small heat dissipation for being more conducive to current insurance silk of area, avoids it from being damaged by the influence of normal working temperature in charger body.
Preferably, the interconnecting piece is provided with insulating protective layer close to one end of the mounting portion.
The surface for the first pin and the second pin that insulating protective layer is used to that socket part will likely to be leaked out wraps up, from
And it prevents from causing short circuit because foreign matter is fallen on it.
Preferably, the notch of the protector is additionally provided with capping, and the protector is articulated with above the capping
Top edge.
Capping comes for protector to be isolated from the outside, and the foreign matters such as dust is avoided to enter protector.
Further, the capping is articulated with the protector by elastic hinge, and the lower end of the capping with it is described
Mounting portion offsets.
Elastic hinge for so that capping be opened after automatic closure, while when capping is closed automatically, can also be by mounting portion
It back into protector.
The principles of the present invention, effect are further illustrated with reference to above-mentioned technical proposal：
In the utility model, the first pin is electrically connected by current insurance silk thereon with circuit board, when charger is short
Lu Shi, the electric current through overcurrent safety silk can increase, the fusing of current insurance silk, the internal wiring of the first pin and charger body
It disconnects, avoids the short circuit for causing socket, cause safety accident.
