Embodiment

The plug of unexamined comprises a body 11, and for example, this plug can connect and be fixed to connector block or socket 12 as shown in Figure 2.

The body 11 of plug is made of the lid 14 of a base shell 13 and a complementation.

Base shell 13 has rear wall 13 ', wherein be assembled with in corresponding recess 15 and be used to receive the phase conductor head of cable (not shown) and terminals and/or flexible contact 16 and the interactional circle or the flat pin 17 that is connected of earthing conductor head, described connection pin 17 stretches out and is used for being connected device plug piece or socket 12 corresponding jacks 18 receptions from described rear wall 13 '.Base shell 13 also has one at the one end and is used to opening 19 that cable is passed through, and side has the device 20 that is used for the locking cable within it.If desired, can seal be set at the outer surface and the inner surface of rear wall.

Lid 14 interacts with base shell 13 so that can be turned to the make position that an open position and that rises of socket body is fallen.More precisely, lid 14 is hinged on an end of base shell 13-promptly and has the relative end in end that makes the opening 19 that cable passes through in one side (21 place), and be provided with a flexible closing hook 22 at its opposite side, this closing hook 22 with one and base shell 13 all-in-one-piece locking bars 23 engage so that lid is locked at its make position.

Base shell 13 is provided with a pair of flexible latch hook 24 that stretches out from rear wall 13 ' at mid portion, and the end of each latch hook 24 side within it all is a copulational protuberance 25, and all is a thicker part or a protuberance (cam) 26 outside it.

Electrical socket 12 has two recesses 27 that are used to admit latch hook 24, is provided with to be used for the anchor plate 28 that engages with the copulational protuberance 25 of latch hook in each recess 27.

Thus, lid 14 has the dead bolt 29 and a pair of flexible latch hook 30 towards base shell 13 at the height place of a pair of latch hook 24 that is positioned at base shell 13, each flexible latch hook all has a retention tab 31 in its outside, this retention tab 31 and relative stop (bottom) grooving that is shaped on base shell 13 32 interactions.

Disconnect at plug 11 and electrical socket 12 and to be connected and to cover under 14 situations about opening fully, the latch hook 30 of lid 14 be connected with corresponding stop grooving 32 disengagements on the base shell 13 also with it away from, and dead bolt 29 is away from latch hook.Therefore, can be fully near the inboard of plug in case stube cable also/or carry out any operation that other needs.

Then, thereby lid 14 upsets can be closed on the base shell 13: at first only make and cover 14 part closures, snap onto on the corresponding stop grooving 32 and dead bolt 29 close latch hooks 24 until the tooth/retention tab 31 of latch hook 30; Dead bolt 29 will be engaged with latch hook 24.

Under the situation of cover closure,,, plug is connected to electrical socket 12 so that the circular or flat connection pin of plug inserts corresponding nest groove fully so can operate plug safely owing to also do not reach electrical components inside.Simultaneously, the latch hook 24 of base shell 13 enters in the interior corresponding recess 27 of electrical socket, and the anchor plate 28 in the described recess of projection 25 contacts of described latch hook.Increase pressure snaps on the locking bar 23 closing hook 22 of lid, thereby will cover closed fully.Under the fully closed situation of lid, dead bolt 29 moves along corresponding latch hook 24, thereby interacts than thickness portion 26 with the outside of latch hook 24, makes the projection 25 of described latch hook 24 engage corresponding anchor plate 28.

Basically, grasp, plug can be connected on the electrical socket, can closedly fully also forever be connected on the electrical socket by means of latch hook 24 plugs by single manual activity and maintenance.So closed fully as long as lid keeps, dead bolt 29 can be kept engaging of latch hook 24 and corresponding anchor plate 28, is disconnected from electrical socket by the plug of unexpectedly or unintentionally opening and cause thus so that prevent plug.In fact, can only plug be disconnected from socket: promptly with the restriction that engages of 32 of stop groovings cover is opened by the latch hook 30 of lid, accordingly, dead bolt 29 is removed so that this latch hook 24 can be disengaged with corresponding anchor plate 28 from latch hook 24, thereby plug can be disconnected from electrical socket.
