Fig. 9 is the action schematic diagram of plug insertion socket among the utility model one rotary type electric connection device embodiment.Rotary type electric connection device for present embodiment, the user can be with the holding portion of the moving plate of the protective door assembly on the first hard contact alignment socket of the grafting bolt bottom surface of plug, plug is exerted pressure, grafting keyhole with plug insertion socket, wherein first projection on the plug can slide along the insertion gathering sill of grafting keyhole hole wall, the pilot hole of the axis of guide at keyhole center and grafting bolt of pegging graft simultaneously also plays the effect of guiding, prevents the crooked of bolt of pegging graft.
Protective door assembly be subjected to the pegging graft pressure of bolt also moves downward simultaneously, and the back-moving spring between protective door assembly and the grafting keyhole bottom is compressed.When arriving the top of first projection arrival insulating trip, be insulated sheet and block, pegging graft this moment to be bolted to reaches the end position that straight line inserts.Simultaneously, the protective door assembly also enters the precalculated position, make two power electrodes of two power electrodes of first hard contact that is spatial distribution and second hard contact and all realize isolating as the grounding electrode of first projection, form the absolute electrode storehouse, prevent sparking, arcing, improve life of product, ensure Electrical Safety.
Stator in the protective door assembly is because the limiting structure in the base can not rotate at this moment, and the axis of guide has also played the effect of restriction stator rotation simultaneously.In the downward pressure that keeps perpendicular to base plane, the grafting bolt is applied along the predetermined direction twisting resistance of (as clockwise).As the cross spacing chute rotation that the grounding electrode of first projection forms along earthing module and insulating trip respectively, first hard contact of the bolt bottom of pegging graft simultaneously drives the moving plate rotation, and because of the stator transfixion that is tied, back-moving spring is subjected to twisting resistance and deforms.
When the predetermined initial angle of grafting bolt rotation (spending) as 10, in the time of also keeping certain safe distance between first hard contact and second hard contact, as the grounding electrode of first projection can with the CONTACT WITH FRICTION of going ahead of the rest of the grounding electrode that is provided with in the chute, and under the pressure of separately spring, continue to keep the excellent contact state.
Continuation rotation along with the grafting bolt, second hard contact be subjected to simultaneously respectively pegging graft first hard contact on the bolt edge part arc surface lasting extruding and begin to move downward, the end face of first hard contact begins to contact with the upper surface of second hard contact respectively then.When rotating to predetermined angular (as 90 degree), grounding electrode as first projection is subjected to the restriction of the end face of chute can not continue rotation respectively, this moment, the end face of first hard contact contacted with the complete planar friction in the upper surface of second hard contact respectively, and the contact pressure of remaining valid under the effect that holds out against spring between second hard contact and the base.
This moment, first hard contact was in complete conduction state with second hard contact respectively under the common maintenance of above-mentioned pressure and torsional forces, and grounding electrode also all can keep the excellent contact state.In rotary course, the mutual friction mutually on two planes that are in contact with one another by first hard contact and second hard contact can also be removed the dust and the dirt that may exist, and guarantees the reliability that is electrically connected.
At the rotation end position, under the state of removing above-mentioned pressure and twisting resistance, under the effect that holds out against spring, the grafting bolt is subjected to the pressure of second hard contact, along the rightabout resilience preset distance (as 1mm) that inserts, drive enters the gathering sill of extracting in the earthing module as the grounding electrode of first projection, and is subjected to extracting the no longer resilience of restriction of the bending part of the bending in the gathering sill simultaneously.
First projection is subjected to the restriction of the two sides of chute passage and can not rotates forward and backward, can prevent the generation because of the accident power-off that circles round in electrode storehouse.The producer can withdraw from the required withdrawal force of grafting bolt by bending angle or the bending of adjusting bending and the straight line of extracting between the gathering sill of can controlling that holds out against spring.
When the user need disconnect when being electrically connected, can select two kinds to extract mode: a kind of is the power-down mode of resilience again of circling round after being pressed into, and a kind of is that straight line is extracted power-down mode.
The process of power-down mode of resilience again of circling round after being pressed into comprises: apply the pressure consistent with direction of insertion at first for the grafting bolt, the rotation end position when making grounding electrode as first projection be retracted into energized from extract gathering sill; The opposite torsional forces of screw-in direction when applying with energized for then the grafting bolt again makes first projection on the grafting bolt receive rotation starting position when circling round to energized in the cross spacing chute that ground module and insulation cushion form.
In this rotary course, the contact area of first hard contact and second hard contact reduces gradually, finishes outage until breaking away from fully.And at this moment still in chute, continue rotation as the grounding electrode of first projection, and keep the excellent contact state with grounding electrode in the chute, guaranteed the connected mode on disconnecting ground, first outage back like this.In this rotary course, the moving plate that first hard contact drives the protective door assembly simultaneously circles round, and the position before not rotating when recovering moving plate to energized, and this moment, the holding portion of moving plate was blocked by the occlusion part branch of stator.
Circle round when putting in place at the grafting bolt, releasing is added in above-mentioned torsional forces and the pressure on the grafting bolt, the protective door assembly recoils to initial position at the active force lower edge of the back-moving spring axis of guide, and first projection that the resilience of protective door assembly drives on the grafting bolt withdraws from along inserting gathering sill.So far finish the power-down mode of the resilience again of circling round after being pressed into of electrical connection and return to initial position.
The process that straight line is extracted power-down mode comprises: during the needs outage, particularly when the chance emergency needs fast break, directly the grafting bolt is applied the pulling force opposite with direction of insertion.Under the effect of this pulling force, first projection on the grafting bolt overcomes the restriction of bending, makes first hard contact of grafting bolt bottom break away from second hard contact moment of grafting keyhole bottom respectively, finishes outage.
Because after the outage, the exterior arc surface of first projection still keeps contacting of a segment distance with bending, first projection withdraws from from extracting gathering sill then, then peg graft bolt bottom first hard contact respectively from the protective door assembly holding portion of moving plate withdraw from, the bolt of pegging graft this moment withdraws from fully, and this mode has guaranteed the connected mode on disconnecting ground, first outage back.
In the time of outage, the protective door assembly is in the axis of guide resilience of the active force lower edge of back-moving spring, because stator can not be rotated by the restriction of the above-mentioned axis of guide, therefore when withdrawing from fully in the first hard contact driven disc, moving plate in the protective door is circled round by the effect of back-moving spring, and be subjected to the boss on the moving plate and the restriction of the block on the stator, circle round to the home position of protective door assembly, the step of moving plate returns to the bottom surface that leans in the guide through hole of top cover then, positive stop lug boss snaps in the draw-in groove at the guide through hole edge of top cover, so far finishes the straight line of electrical connection and extracts outage and return to initial position.
