Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the preferred embodiment of the utility model electric connector.
Fig. 2 is the perspective exploded view of the preferred embodiment of the utility model electric connector.
Embodiment
As shown in Figure 1, a kind of electric connector of the utility model is in order to transmit power supply or data, and it comprises insulating body 2, conducting terminal 6, PCBA board 3 and metal shell 1.
PCBA is the abbreviation of English Printed Circuit Board+Assembly, PCBA board is exactly that PCB hollow plate is through SMT(Surface Mount Technology, surface mounting technology) go up part, again through DIP(dual inline-pin package, also dual in-line package technology is) plate that formed after the whole processing procedure of plug-in unit, is called for short PCBA board.
Conducting terminal 6 is contained in described insulating body 2, metal shell 1 coated insulation body 2 forms spliced eye 7, as shown in Figure 2, conducting terminal 6 has the contact site 61 extended in spliced eye 7 and the welding foot 62 be soldered in PCBA board 3, PCBA board 3 is provided with the transducer 4 and switch 5 that are mutually electrically connected.
Transducer 4 contacts with the closed of the temp control switch 5 according to metal shell 1 and disconnection with metal shell 1, detailed process is: metal shell 1 is provided with the Extendible flake 9 contacting described transducer 4 end face, transducer 4 is clamped between described Extendible flake 9 and PCBA board 3, such transducer 4 can detect the temperature of metal shell 1, at transducer 4 when the temperature on metal shell 1 being detected lower than critical temperature, continue energising by high-frequency signal control switch 5; When the temperature on metal shell 1 being detected higher than critical temperature, by high-frequency signal control switch 5 power-off.
In the present embodiment, the critical temperature of metal shell 1 is 45 DEG C, is understandable that, can according to the requirement of manufacturer, critical temperature is heightened to 50 DEG C, 55 DEG C, 60 DEG C etc., and also can turn down is 40 DEG C, 35 DEG C etc., and this depends on the model of transducer.Auto-breaking when critical temperature allows electric connector not be unplugged at long-time transmission power supply really surely, avoids electric connector to burn, the generation of the accident such as blast.
In addition, whether switch 5 can equal grounded circuit electric current according to the output current of self, carries out the switching between closing and disconnecting.Detailed process is: switch 5 can detect output current and ground connection back flow current, when detecting that output current equals grounded circuit electric current, switch 5 continues energising, detecting that output current is not equal to grounded circuit electric current once switch 5, switch 5 auto-breaking, such can make user transmit continue to use electronic product under power supply status time, when there is electric leakage and auto-breaking, avoid occurring personal accident accident.
This electric connector also comprises the formation type coordinated with metal shell 1 and to insulate external mold (not shown on figure) and cable (not shown on figure), and PCBA board 3 is electrically connected conducting terminal 6 and cable.
The tubular cabinet portion 11 that metal shell 1 comprises coated insulation body 2 and the U-shaped collecting sheet 12 extended back from frame 11, Extendible flake 9 extends back from frame 11 top to form, Extendible flake 9 is positioned at the top of collecting sheet 12, and PCBA board 3 is positioned at collecting sheet 12.
Transducer 4 and switch 5 are located at the upper surface of PCBA board 3 and separate between left and right, and conducting terminal 6 is welded on the lower surface of PCBA board 3.
The some golden fingers 8 welded with cable are also provided with at the upper surface of PCBA board 3 rear end.
Transducer 4 and switch 5 are welded in PCBA board 3, certainly, also can adopt other the usual fixed forms in this area.
In the present embodiment, metal shell 1 is integrated, but if divide body formed, energy heat-conductivity conducting between each formed body, also can realize function of the present utility model, be equivalent embodiments of the present utility model, all within protection range of the present utility model.
Enforcement the beneficial effects of the utility model are: when this electric connector can not be unplugged at long-time transmission power supply, when the temperature of metal shell 1 being detected higher than critical temperature, transducer 4 is by high-frequency signal control switch 5 power-off; This electric connector can also when detecting that output current is not equal to grounded circuit electric current, switch 5 auto-breaking, and structure is simple, easy to use.
Although be example object, disclose preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
