When high-tension connector was communicated with, the boss of buckle was in b place, hole, and rocking bar is positioned at the buckle below and can't opens, when disconnecting high-tension connector, the boss of buckle is pushed in a of hole from hole b, and rocking bar upwards lifts certain angle, blocked by buckle, at this moment, the high pressure interlocking loop disconnects, male end terminal and female end terminal are still connected, buckle is depressed, made boss move to hole b from hole a, continue the pull-up rocking bar to the upright position, male end terminal and female end terminal disconnect, thereby realize opening circuit delay function.

Described rocking bar is U-shaped, and its openend is fixed on the male end terminal by rotating shaft, and its blind end is provided with cross bar, and when rocking bar was horizontally disposed with, cross bar was positioned at described buckle below, rocking bar can't upwards be lifted open, thereby guarantee that the connector safety and stability is communicated with.

The openend both sides of described rocking bar are provided with axis hole, and the rotating shaft a on this axis hole and the male end terminal is rotationally connected, and described axis hole below is provided with the waveform chute, and this chute is connected with rotating shaft b on the male end terminal, and when rocking bar lifted, rotating shaft b slided in chute.

Described buckle both sides and draw-in groove are complementary, and the boss top of buckle is provided with block, and during the rocking bar pull-up, the cross bar of block and rocking bar is collided, and rocking bar can't be lifted.

The boss of described buckle is in a of hole, and the angle that rocking bar upwards lifts is the 30-60 degree.

Compared with prior art, the present invention has the following advantages: by at the male end terminal draw-in groove being set, fixing buckle and offer the track that buckle slides, the secondary location is realized in two holes of the boss on the buckle and draw-in groove, when high-tension connector is disconnected, progressively disconnect through the secondary location, thereby realize the time-delay break function.

Embodiment

The present invention is described in detail below in conjunction with the drawings and specific embodiments.

Embodiment 1

As described in Fig. 1-3, a kind of off delay structure of high-tension connector, high-tension connector comprises high pressure interlocking loop 5, male end terminal 3, female end terminal 4, described male end terminal 3 is connected with female end terminal 4 couplings, described high pressure interlocking loop 5 is arranged in the female end terminal 4, also be provided with the off delay structure on the described male end terminal 3, this off delay structure comprises rocking bar 1, buckle 2, draw-in groove 31, hole a32 and hole b33, described draw-in groove 31 is arranged on male end terminal 3 one sides, described hole a32 and hole b33 upper and lower settings are in draw-in groove 31 1 sides, described buckle 2 is complementary with draw-in groove 31, draw-in groove 31 is buckle 2 and offer the track that buckle 2 slides fixedly, buckle 2 is provided with the boss 21 that may be locked among hole a32 or the hole b33, boss 21 tops are provided with block 22, described rocking bar 1 is U-shaped, its openend is fixed on the male end terminal 3 by rotating shaft 34, its blind end is provided with cross bar 11, when rocking bar 1 is horizontally disposed with, cross bar 11 is positioned at described buckle 2 belows, during rocking bar 1 pull-up, block 22 is collided with the cross bar 11 of rocking bar 1, rocking bar 1 can't upwards be lifted open, thereby guarantee that the connector safety and stability is communicated with.
