Fig. 6 is a pushing-type detent mechanism structure cutaway view, Fig. 7 is a pushing-type detent mechanism positioning groove side-looking structural representation: the pushing-type detent mechanism comprises location hook 11, positioning groove 12, positioning groove 12 is V-arrangement stack grooves that communicate suitable for reading of opening in hollow core 6 sides, location hook 11 is Z-shaped colluding, colluding 11-1 on the location hook is fixed on the cap 8, on colluded return spring 14, the following 11-2 of colluding of location hook is positioned at V-arrangement stack groove 12.The 7th, a shell, the 5th, support spring, the 9th, fore-set, the 10th, anti-pushing block.O, Y represent that the following 11-2 of colluding of location hook is positioned at two positions of V-arrangement stack groove 12, corresponding to a low level and the high position in the hollow core 6 present shells 7.
Pushing away hollow core causes potential safety hazard by mistake in order to prevent not have plug, the pushing-type detent mechanism is provided with the anti-device that pushes away of no plug, as Fig. 7, shown in Figure 8: no plug is anti-to be pushed away device and is included in the anti-pushing block 10 that is fixed on the restorable on the hollow core 6 in the jack 4, and the fore-set corresponding with anti-pushing block 9 on being fixed at the bottom of the shell.The 5th, the support spring between hollow core 6 and the seat shell 7.Operation principle is: as Fig. 7, the anti-pushing block 10 of nature rests between fore-set 9 and the hollow core 6; As Fig. 8, when injecting plug, plug 18 has been pushed anti-pushing block 10 aside, allows anti-pushing block 10 leave fore-set 9, makes between fore-set 9 and the hollow core 6 accessiblely, could move downward by plug 18 promotion hollow cores 6.No plug prevents that pushing away device has prevented dangerous displacement.
Fig. 8 is a user mode structure cutaway view of the present invention: further specify operation principle of the present invention and process below in conjunction with accompanying drawing:
The effect of detent mechanism of the present invention is to make the hollow core energising operating state (high position) that rises of (low level) or hollow core in a state of nature.
Under reset condition (low level), the conductive clip 1 of ratchet wheel clamping machine is in as Fig. 1, position shown in Figure 4, be the wide side of helix of conductive clip 1 corresponding to conducting strip upper semisection 1-5 and ratchet 2 because the position of hollow core 6 is in low level, keep certain spacing not contact with the inclination conducting strip 3-1 of power supply terminal 3, at this moment no power.
As Fig. 8, Fig. 5, when pressing plug 18, under the effect of detent mechanism, hollow core 6 rises to a high position, and the conductive clip 1 of band ratchet wheel clamping machine moves upward thereupon, because inclination conducting strip 3-1 is motionless, the wide upper semisection 1-5 of helix is because the strain process, the angle of inclination is tending towards identical with conducting strip 3-1, contacts with conducting strip 3-1 and is close to, and is in "on" position; Simultaneously, conducting strip 3-1 extruding ratchet 2 withstands plug 18, forms clamped condition.At this moment, if when drawing plug 18, because the angle that forms between inclination conducting strip 3-1 and the plug 18, ratchet 2 under the drive of plug 18 when roll in narrow place, top, produce the ratchet locking effect, the tighter plug 18 of clamping prevents to extract, and makes simultaneously between conducting strip 3-1 and the plug 18 and contacts tightr energising better effects if.
Push away plug 18 again one time, hollow core 6 can be got back to low level from a high position, and conductive clip 1 has left conducting strip 3-1 and cut off the power supply at this moment, recovers reset condition, can pull the plug out of the socket.
In adopting the socket of rotary detent mechanism, except that detent mechanism with above-mentioned different, other structure is all identical.
Fig. 9 is rotary detent mechanism structure cutaway view, Figure 10 is that rotary detent mechanism plan structure schematic diagram, Figure 11 are the anti-rotation mechanism of rotary detent mechanism plan structure schematic diagrames: rotatable detent mechanism is included in the both wings 16 that both sides, hollow core 6 bottom are provided with protrusion, corresponding position is provided with transverse concave groove 17 in the present shell 7, both wings 16 have vertical openings 19 in transverse concave groove 17 sides, seat shell in groove 17; The stop pin 15 of anti-rotation mechanism is square, and is positioned in the square groove 20 of cap 8 lower ends, and the other end inserts the groove 6-1 top of hollow core, and back-moving spring 21 is arranged in the square groove 20.
Initial condition, both wings 16 are in groove 17, hollow core 6 is in low level, operation principle is: have only the plug of reeve to push stop pin 15 open, allow stop pin 15 leave hollow core 6, could pass through plug 18 hollow core is rotated an angle, both wings 16 break away from groove 17 and enter vertical openings 19 in the shell, make hollow core 6 arrive a high position.Other is identical with the said structure and the course of work.
Band ratchet wheel clamping machine conductive clip is a most preferred embodiment of the present invention, and when not having ratchet, upper shed ear shape conductive clip also has certain clamping function, but does not have ratcheting, can't produce the ratchet locking effect.
