As, the quality of production is seriously affected, while be easy to causeing the residual of welding slag when welding, influences the beauty of product, however
Some designed by elastic slice, is connected by welding elastic slice on PCB, then by one end of AC pin and elastic slice, still
This mode loosens between AC pin and elastic slice and elastic slice pcb board since prolonged use will lead to, influence using it is steady
Qualitative and safety, and need to be fixedly connected between elastic slice and pcb board, while increasing the complexity of technique.
Utility model content
Based on this, it is necessary to provide a kind of USB traveling charger with power supply adaptor, including power supply adaptor, institute
It states power supply adaptor to include shell and be set to the intracorporal pcb board of the shell, and the AC pin being fixedly installed on the shell,
The edge PTH hole for connecting the AC pin is offered on the pcb board, one end of the AC pin through the shell and plugs
It is placed in the edge PTH hole.
One end of AC pin is inserted in edge PTH hole, and the other end is passed through and shell and is fixed on shell, AC pin by with
The contact of edge PTH hole and be connected with pcb board；Since the utility model is that AC pin is fixed on shell, compared to being welded on
On pcb board, the connection structure of AC pin is more stable；In addition, AC pin can move in edge PTH hole, therefore even if AC pin by
The external force told somebody what one's real intentions are, the connection structure of itself and pcb board will not be destroyed by causing it that relative displacement occurs with pcb board, so that AC is inserted
The electric connection structure of foot and pcb board is more stable.
Preferably, the shell includes that the upper housing of mutual lid conjunction and lower case, the AC pin are set to the lower casing
Body, the pcb board are fixed on the lower case.
AC pin and pcb board are respectively arranged in lower case and upper housing, and upper housing and lower case are separately gathered AC
Pin is easily separated with pcb board, easy to disassemble to repair to it.
Further, the pcb board is fixedly installed in the upper housing by elastic portion, wherein the elastic portion is fixed
It is set to the top of the upper housing.
When upper housing is deformed by external force, elastic portion can permit pcb board and certain displacement occurs for shell, thus
Pcb board deformed damaged is avoided, in addition, a degree of deflection occurs for AC pin, at this time bullet when flexible deformation occurs for lower case
Property portion can permit pcb board and certain displacement occurs for upper housing so that the position of the edge PTH hole on pcb board adapts to AC pin
Deflection.
Further, the elastic portion includes the first elastic portion and the second elastic portion, first elastic portion and the second bullet
Property portion is located at the both ends of the pcb board, and the center line symmetrical setting about the pcb board.
It, can be effectively positioned at first elastic portion at pcb board both ends and the second elastic portion compared to an independent elastic portion
Prevent pcb board from deflecting in use, to guarantee the stability of the connection structure of AC pin and edge PTH hole.
Further, the AC pin is provided with several metallic fibers close to one end of upper housing.
Metallic fiber is connected with AC pin, for guaranteeing that AC pin is connected with edge PTH hole.
Preferably, be additionally provided with reinforcement part in the lower case, the reinforcement part is arranged around the AC pin, and with institute
AC pin is stated to be fixedly connected.
Reinforcement part is fixedly connected with lower case and AC pin, and reinforcement part is used to increase the thickness of lower case, so that AC is inserted
Foot is difficult to deflect relative to lower case, while can increase the contact area of AC pin and lower case, to increase AC pin under
Bonding strength between shell.
Further, the reinforcement part and the lower casing body by integral forming are arranged.
Its structural stability of integrally formed structure is more preferable, structural strength is higher.
The principles of the present invention, effect are further illustrated below with reference to above-mentioned technical proposal:
One end of AC pin is inserted in edge PTH hole, and the other end is passed through and shell and is fixed on shell, AC pin by with
The contact of edge PTH hole and be connected with pcb board；Since the utility model is that AC pin is fixed on shell, compared to being welded on
On pcb board, the connection structure of AC pin is more stable；In addition, AC pin can move in edge PTH hole, therefore even if AC pin by
The external force told somebody what one's real intentions are, the connection structure of itself and pcb board will not be destroyed by causing it that relative displacement occurs with pcb board, so that AC is inserted
The electric connection structure of foot and pcb board is more stable.
