Then, the beginning separated from one another of cap shell 10 and plug body 20, and therefore power connector end 101 is partly separated each other with the sub-tap 203 of power connector end, and the attachment plug 103 and interlock and be connected tap 203 and be separated completely each other of interlocking.Now, guide protrusion 33 runs into the second section of moving horizontally 315c perpendicular to vertical mobile section 315b, and the separated from one another interim stopping of therefore power connector end 101 and the sub-tap of power connector end 201.
Namely, is connected tap 203 separated from one another after the second section of moving horizontally 315c stops along separation and power connector end 101 and the sub-tap of power connector end 201 completely each other while vertical mobile section 315b movement of guide protrusion 33 temporarily in interlocking attachment plug 103 and interlocking, power relay 110, is stopped power supply along dead short circuit while the second section of moving horizontally 315b movement thus at guide protrusion 33.
After this, when cap shell 10 and plug body 20 be pulled continuously dynamic and be therefore separated completely each other time, as illustrated in fig. 9, guide protrusion 33 is moved along bending mobile section 315d and is left by the entrance entering path of navigation 313.
Now, when guide protrusion 33 moves along bending mobile section 315d, the elastomeric element 35 of compression recovers, to be conducive to the movement of guide protrusion 33, and the guide member 31 entering the inside of guide member installation portion 37 is drawn out of, to return to its home position.
Therefore, at guide protrusion 33 along while vertical mobile section 315b movement, interlocking attachment plug 103 is connected tap 203 with interlocking and is separated completely each other, and, accurately discharged in the connection of power relay 110 and reached guide protrusion 33 after the time of the second section of moving horizontally 315c, when guide protrusion 33 moves along bending mobile section 315d, power connector end 101 and power connector end tap 201 separated from one another.Correspondingly, connect between tap 203 time separated from one another and the connection d/d time of power relay 110 in interlocking attachment plug 103 and interlocking, produce all the time with guide protrusion 33 along time difference corresponding to the time of the second section of moving horizontally 315c movement.
Therefore, after interlocking attachment plug 103 and the interlocking connection connected between tap 203 are released, connector 1 guarantees time enough for power relay 110 short circuit, thus when power connector end 101 is separated with the sub-tap 201 of power connector end, prevent electric arc from producing between power connector end 101 and the sub-tap 201 of power connector end.
Figure 10 is the view of the guide member of the high-tension connector illustrated according to another embodiment of the present invention.Only comprise a path of navigation 316 according to the guide member 31' of this embodiment, itself and be equal to according to the path of navigation 315 that leaves of the guide member 31 of embodiment before this, thus make guide protrusion to be entered by same paths and to leave guide member 31'.
In more detail, guide protrusion enters and leaves guide member 31' by identical path of navigation 316, to extend interlocking attachment plug being connected the tap time separated from one another with interlocking, and, path of navigation 316 comprises bending mobile section 316a, the first section of moving horizontally 316b, vertically mobile section 316c and the second section of moving horizontally 316d, so that the side of the initial position entered at guide protrusion 33a or opposite side detour.
If cap shell 10 and plug body 20 are connected to each other, then first guide protrusion 33a enters bending mobile section 316a, and therefore power connector end 101 is connected with the sub-tap 201 of power connector end, interlocking attachment plug 103 is connected tap 203 with interlocking and is then connected to each other, and guide protrusion 33b moves along vertical mobile route 316c simultaneously.
Now, guide member 31' enters the inside of guide member installation portion 37, and elastomeric element 35' is compressed simultaneously.
Then, be moved horizontally to the end of the second section of moving horizontally 316d at guide protrusion 33d while, power relay 110 is accurately connected and cap shell 10 and plug body 20 are accurately connected to each other, and guide protrusion 33d is not easy to depart from path of navigation 316.
Now, compression elastomeric element 35' recover and guide member 31' returns to its home position.
On the other hand, if cap shell 10 and plug body 20 separated from one another, then when worker pull temporarily guide member 31' with guide protrusion 33d is separated with the second section of moving horizontally 316d and then pull cap shell 10 and plug body 20 with by cap shell 10 and plug body 20 separated from one another time, guide protrusion 33c moves along vertical mobile section 316c towards the first section of moving horizontally 316d.
Then, in the mode identical with embodiment before this, the movement of guide protrusion 33b the first section of moving horizontally 316b stop temporarily and interlock attachment plug 103 and interlocking to be connected tap 203 separated from one another, and, at guide protrusion 33b along while the first section of moving horizontally 316b movement, power relay 110 is separated completely.
At this, then elastomeric element 35' by temporal compression, and returns to its home position when guide protrusion 33a moves along bending mobile section 316a.
Therefore, when cap shell 10 is separated each other completely with plug body 20, prevent electric arc from producing between power connector end 101 and the sub-tap 201 of power connector end, as mentioned above.
