As shown in Figure 5, be the structural representation of the top cover of the electric-connected socket among the present invention one rotary type electric connection device embodiment.Top cover 200 comprises lid 201, and the through hole 210 that Electric plug with shutter 100 inserts can be set on lid 201, is convenient to Electric plug with shutter 100 insertions and cooperates through hole 210 to rotate by cylindrical profile; Also through hole can be set, be convenient to the chute that first hard contact tangentially moves and directly be provided with on the surface of top cover 200.
The spacing horizontal concrete chute 211 of the spacing block set of header body 101 and socket has constituted the electrical connection retaining mechanism that first hard contact that makes plug 100 tightens after inserting socket and rotating predetermined angular.
Except above-mentioned electrical connection retaining mechanism, be electrically connected retaining mechanism other implementation can also be arranged, for example spacer pin is set in header body, the spacing hole that cooperates with spacer pin is set at the socket top, be provided with back-moving spring between spacer pin and header body, spacer pin is subjected to the effect of back-moving spring and stretches out from the bottom of header body.When the plug bottom surface touches socket, spacer pin is subjected to the pressure of receptacle face and the header body of withdrawing, and after plug rotates to predetermined angle, spacer pin is aimed at spacing hole, this moment, spacer pin was owing to be subjected to the effect of back-moving spring, stretch out header body, and enter spacing hole, thereby finish the locking of electrically connecting position.
Electric plug with shutter need rotated back to the scene that initial position is extracted, can be at the releasing spacing block set that axially is subjected to displacement that prolongs of the sidewall setting of header body and spacer pin interlock, the user is by stirring the releasing spacing block set to the power of extracting direction, drive spacer pin and break away from spacing hole, thereby remove the locking of electrically connecting position.
Embodiment below in conjunction with a rotary type electric connection device of the present invention illustrates the running flow process of each parts of device in use.
After the hand-held Electric plug with shutter of user inserts electric-connected socket, wherein the spacing block set of Electric plug with shutter is aimed at vertical the insertions mouth of the spacing horizontal concrete chute that the top cover of electric-connected socket is provided with, after the insertion, spacing block set enters vertical insertion mouth, two first power electrodes and one first grounding electrode of Electric plug with shutter are inserted into guiding groove simultaneously, and second rotating shaft of socket base is inserted into first pilot hole of header body bottom.
The user imposes certain moment of torsion to header body, two first power electrodes and one first grounding electrode of Electric plug with shutter slide along guiding groove, and wherein second grounding electrode of electric-connected socket contacts with first power electrode prior to two second source electrodes with first grounding electrode of plug.Simultaneously, spacing block set is subjected to the pressure retraction header body of chute inwall, and the retainer spring between compression spacing block set and the header body.After rotating to predetermined angle, first power electrode screws between two sheet metals of second source electrode, be subjected to the effect of the elastic force of the clamping force of sheet metal self and holddown spring, the power electrode of winning is closely contacted with the second source electrode, first grounding electrode also closely contacts with second grounding electrode simultaneously, the mouth of vertically extracting that spacing block set slides into spacing horizontal concrete chute blocks, the restriction header body can not be rotated forward and backward, can prevent the generation because of the accident power-off that circles round of header body.
When the user wished to disconnect electrical connection, can select dual mode: a kind of was directly to extract, and a kind of is that extract cycle insertion front position again.
The process of the mode of directly extracting comprises: during the needs outage, particularly when the chance emergency needs fast break, the user imposes the pulling force opposite with direction of insertion to header body, under the effect of this pulling force, first hard contact of header body bottom overcomes the thrust and the second hard contact moment disengaging of second hard contact of socket, finishes outage.Meanwhile, the spacing block set on the header body is deviate from from the mouth of vertically extracting of the spacing horizontal concrete chute at electric-connected socket top.First grounding electrode can be designed to the mode longer than first power electrode usually, disconnect when being connected between such first power electrode and the second source electrode, still keep excellent contact between first grounding electrode and second grounding electrode, guaranteed the connected mode on disconnecting ground, first outage back like this.
The process that extract cycle insertion front position again comprises: at first exerts pressure to the releasing spacing block set on the header body, because this removes spacing block set and spacing block set interlock, so spacing block set retraction header body, remove and the vertical state that blocks of extracting mouth.The opposite torsional forces of screw-in direction when the user applies with energized for header body more then, the rotation starting position when making header body circle round to energized.
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 first grounding electrode still keeps the excellent contact state with second grounding electrode when outage, has guaranteed the connected mode on disconnecting ground, first outage back like this.In this rotary course, spacing block set slides along spacing horizontal concrete chute inwall.
Circle round when putting in place in header body, the user imposes the pulling force opposite with direction of insertion, and first hard contact is broken away from from electric-connected socket.So far finishing cycle inserts the power-down mode of extracting again the front position and returns to initial position.
