Embodiment
The embodiment one of the connector of the present invention：As Figure 1-3, including connector shell and in housing
Intraware.Wherein, the structure of intraware is fixed on bottom plate 11 and is connected by screw as shown in figure 1, including fixed bottom plate 11
There is printed circuit board 12, positive and negative electrode conducting strip 20,23 has been conductively connected on printed circuit board 12.Positive and negative electrode conducting strip 20,23
Extend in fore-and-aft direction and be set up in parallel in left and right directions, positive and negative electrode conducting strip 20,23 is used in fore-and-aft direction with being adapted to
The both positive and negative polarity copper bar of socket or plug connector carries out grafting.On printed circuit board 12 also after positive and negative electrode conducting strip 20,23
Side is welded with the positive and negative electrode terminals 8 for connecting load A, and positive and negative electrode terminals 8 include the line ball spiral shell being located on wire guide
Nail, positive and negative electrode terminals are corresponded to and are conductively connected with positive and negative electrode conducting strip 20,23 respectively by printed circuit board 12.
Precharge conducting strip 22 is also welded with printed circuit board 12 in the front side of cathode conductive film 23, in connector grafting
When, precharge conducting strip 22 is connected prior to cathode conductive film 23 and power cathode, and turns on loop jointly with cathode conductive film 20.
Electric capacity 5 is also welded with printed circuit board 12, electric capacity 5 is serially connected between precharge conducting strip 22 and negative terminals, in order to promote
The both ends of electric capacity are quickly established in a short time when enabling to turn on loop in precharge conducting strip and power electrode contact
Certain voltage, also it is welded with and the backward dioded of capacitance series 3 on printed circuit board 12.Also welded on printed circuit board 12
Limited leakage resistance 4, current-limiting resistance 4 are connected in parallel on the both ends of backward dioded 3, and when connector grafting is complete, i.e., positive and negative electrode is conductive
When piece contacts conducting with power electrode respectively, the electric energy of storage can be discharged by current-limiting resistance 4 in electric capacity 5, and current-limiting resistance 4 consumes
