Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, three pole sockets with three utmost point shutters that the utility model provides comprise socket panel 1 and base 2, between socket panel 1 and base 2, be provided with L/N utmost point shutter 3, earth polar driving chip 4 and back-moving spring 5, the L utmost point jack 11 of socket panel 1 and the outside of N utmost point jack 12 have locking groove 13, and between the two, have the sliding tray 14 of strip, the top of L/N utmost point shutter 3 is respectively equipped with and locking groove 13, stop shoulder 31 and slip muscle 32 that sliding tray 14 is suitable, be respectively used to limit moving forward and moving left and right of L/N utmost point shutter 3, in present embodiment, sliding tray 14 and slip muscle 32 are respectively side by side two.The middle part of L/N utmost point shutter 3 has groove 36, formation thin-walled connects, left and right portion is respectively equipped with for promoting it to the driving inclined-plane 33 of front slide, drive below, inclined-plane to be provided with the ladder 35 suitable with earth polar driving chip, the front portion of L/N utmost point shutter 3 be provided with one towards under the hasp 34 of hook solid, earth polar driving chip 4 is T shape, left and right portion be provided with L/N utmost point shutter 3 bottom surfaces suitable towards upper ladder position 41, middle part has the groove 42 suitable with hasp 34, the front end of groove 42 is provided with driving inclined-plane, earth polar 43, the top of earth polar driving chip 4 is resisted against on back-moving spring 5.
On base 2, be respectively equipped with N utmost point sleeve, L utmost point sleeve and the earth polar sleeve corresponding with 1 three jacks of socket panel.
Under the active force effect of plug or socket panel 1, left and right two parts of L/N utmost point shutter 3 can be to lower swing, extruded channels 36, and when active force disappears, it can restore to the original state the elasticity connecting because of thin-walled.
After the utility model assembling, the constraint of L/N shutter and earth polar driving chip is as follows:
L/N utmost point shutter 3: the front and back of establishing L/N utmost point shutter 3 are Y-direction, left and right is directions X, is Z direction up and down, and the slip muscle 32 on L/N utmost point shutter 3 and the sliding tray of socket panel 1 14 coordinate, and constraint directions X moves and rotates around Z axis; Socket panel 1 and base 2 constraint Z directions move and rotate around X and Y-axis; The movement of stop shoulder 31 and locking groove 13 fiting constraint Y-directions, when this constraint release, L/N utmost point shutter 3 can move along Y-direction.L/N utmost point shutter 3 is intermeshing with the step surface of earth polar driving chip 4, has filled up gap between panel and base, makes L/N shutter cannot do the motion of Z direction.
Earth polar driving chip 4: socket panel 1 and base 2 constraint Z directions move and rotate around X and Y-axis; Move and rotate around Z axis with the fiting constraint directions X of L/N utmost point shutter 3; Y-direction can move.
The square plug that meets British Standard BS1363 inserts and withdrawal process:
1, as shown in Figure 4, plug starts to insert, and earth polar latch is longer, is introduced into earth polar jack;
2, the earth polar latch of plug acts on the inclined-plane of earth polar driving chip, and earth polar driving chip is promoted to the right, and the step surface of itself and L/N utmost point shutter is departed from;
3, the L utmost point of plug and the N utmost point simultaneously by left and right two parts of L/N utmost point shutter to pressing down, stop shoulder is pushed away to the locking groove of socket panel;
4, the inclined-plane of the L of plug and the latch effect of the N utmost point and L/N utmost point shutter, L/N utmost point shutter is promoted to the right, and the step surface of its step surface and earth polar driving chip meshes in the position of the step that staggers the promotion state that enters again;
5, the inclined-plane of the L of plug and the continuation effect of N utmost point latch and L/N shutter, promotes L/N shutter to the right, and L/N utmost point shutter promotes earth polar driving chip and moves right, and plug inserts socket completely;
6, as shown in Figure 5, when plug is extracted, L, N utmost point latch are extracted in advance, the spring force promotion earth polar driving chip and the L/N utmost point shutter that act on earth polar driving chip are moved to the left, when the stop shoulder of L/N utmost point shutter is got back to panel sulculus position, because self elastic force makes L/N utmost point shutter, reply nature, its stop shoulder falls into sulculus, and the step surface of L/N shutter and earth polar driving chip departs from the engagement of promotion state;
7, with plug continue extract, earth polar latch is extracted from the jack of earth polar, spring force promotes earth polar and drives film gate to be moved to the left, and makes itself and L/N utmost point shutter return to original engagement, whole plug process finishes.
Stop improper insertion:
1, single latch inserts from hole, socket earth polar: now earth polar driving chip can be open, and latch inserts earth polar jack.But earth polar driving chip and L/N shutter are relatively independent, L/N shutter is fixed by stop shoulder, with earth polar driving chip, do not move, so the L of socket, N utmost point jack still crested live, play a protective role.And common earth polar drives shutter, now L, N utmost point jack are opened.
2, single latch is from socket L(N) utmost point hole inserts: because of the step of earth polar driving chip and L/N shutter intermeshing; upper and lower have panel and base spacing; when latch promotes L/N utmost point shutter L(N) during utmost point inclined-plane; due to panel locking groove stopping stop shoulder; L/N utmost point shutter cannot move; so L(N) still crested of utmost point jack, plays a protective role.
3, two latches insert from socket L, N utmost point hole simultaneously: when L, N utmost point jack have latch to insert simultaneously; L/N shutter and earth polar driving chip mesh; L/N shutter cannot be done amoeboid movement; the stop shoulder of L/N utmost point shutter still can be maintained in the sulculus of panel; cause L/N shutter to move; covering of L/N utmost point jack is not disengaged, plays a protective role.
4, two latches are from socket ground, L(N) utmost point hole inserts simultaneously: 1. earth polar slotting makes earth polar driving chip reach, makes itself and L/N shutter depart from original engagement; 2. L(N) utmost point latch makes the L(N of L/N shutter) side moves down, and makes this side stop shoulder depart from the sulculus of panel; 3. N(L) stop of utmost point side L/N shutter shoulder is still stayed in sulculus; L/N shutter cannot be moved forward; the cooperation of sliding tray and slip muscle simultaneously; L/N shutter cannot be rotated; consequently the L utmost point cannot insert; vice versa, and common earth polar drives shutter, and now L, N utmost point jack are opened.
Similar products (three pole sockets) shutter is that single-stage drives, and after normal mounting is used, needs only a hand, holds the instrument of a similar screwdriver, just its shutter can be promoted, and live part is exposed.And use three pole sockets of the present invention, two hands to hold the instrument of similar screwdriver simultaneously, and all its shutter cannot be pushed open, thereby live part can not expose, greatly increased security performance.
The action of only inserting three pole sockets at complete mock standard three-terminal polarized plus plug according to the shutter of the utility model design; shutter could be pushed open; the L of socket, N utmost point jack just can expose; latch shape thing just can touch charged sleeve, has at utmost limited the abnormal operation power taking to three pole sockets.Accomplish to insert pin or club from socket any one or two jacks, the shutter of socket cannot be open, and legal plug can insert smoothly.
The utility model has the advantages that: increase socket secure, at utmost prevent children's two hands simultaneously use instrument push the shutter of socket aside, and the electric shock that meets accident.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
