The cross current connection apparatus of the utility model is compared with existing current connection apparatus, has the following advantages:

1. cross connects be flexible coupling with the air contact area than 4 times of traditional raisings, so good heat dissipation is not easy heating, electric current output is bigger than traditional;

2. what cross connected is flexible coupling and can very easily dismantles;

3. the monolithic that is flexible coupling of cross connection is thinner, and also the operating physical force than traditional is little even 4 add together;

4. 4 stress that are flexible coupling of cross connection are cancelled out each other, and have prolonged the life-span of arc control device;

5. the fault-tolerance that is flexible coupling of cross connection is better than the conventional softer connection, even a slice is damaged or be loosening, package unit can also guarantee 75% use; After breaking down, being flexible coupling that cross connects can also keep 80% reliability;

6. the difficulty of processing that is flexible coupling of cross connection connects reduction than conventional softer;

7. the contact area of the current output terminal of conventional current jockey is littler one times than the area of the current output terminal of cross current connection apparatus, so conventional current jockey contact resistance is bigger than cross current connection apparatus contact resistance.
