Abstract

An electrical socket with a shutter mechanism for an electrical connector An electrical socket includes a shutter mechanism to prevent misuse of the socket. It prevents insertion of objects to connect to the electrical terminals other than the appropriately configured plug. The shutter is formed from two main components. The first requires insertion of an earth pin in order that it is moved into a position relative in relation to the second in which relative sliding motion is permitted. The second member may then be moved to expose the other terminals by insertion of the other pins. If pins are inserted into the neutral and live terminals whilst the first member is in the initial position the second member rocks or pivots into a position in which arms of the first member prevent relative sliding movement. Thus, the terminals remain covered by the second member preventing connection.

Description

The electrical socket that has the valve mechanism that is used for electric connection
Technical field
The present invention relates to have the electrical socket of the valve mechanism that is used for electric connection.
Background technology
The electrical socket of Britain comprises three terminals, when plug cooperates with socket, can the corresponding pin of plug be inserted in the described terminal.Pin makes it possible to be connected to live wire, zero line and the ground wire of power supply.The target that is provided with valve mechanism is before correctly carrying out ground connection, prevents object is inserted into the misuse in fire line terminal and the zero terminal.Said mechanism requires after the earth pin of inserting plug, just to expose zero terminal and fire line terminal.This has prevented before ground connection, for example screwdriver or other inappropriate objects is inserted in the fire line terminal.
Yet have been found that some existing valve mechanisms are not fully reliably.Because the play in this existing mechanism, secure context may be walked around, thereby might cause the personnel that misapply socket to receive electric shock.
Summary of the invention
Open the present invention is to provide improved valve mechanism.
According to the invention provides a kind of electrical socket; It comprises valve mechanism and a plurality of electric connection; The joint of coupling will be in use and the electric connection coupling, and said valve mechanism is used to prevent and being connected of said electric connection that said valve mechanism comprises: first member; Said first member is close to the first terminal, and can move to retracted position through joint from initial position with cooperating of said terminal; Second member; Said second member is positioned at covering at least the second terminal and is connected to first initial position of said second terminal to prevent joint; When said first member is positioned at said retracted position; Said second member engages said first member slidably to allow the relative motion between said second member and said first member; Thereby permission is connected with said at least one terminal, and when said first member was positioned at said initial position, said second member can be moved under the effect that cooperates with said at least one terminal at joint and pivot; Make said first member of said second member engages move, thereby said second member is remained on the position that covers said at least one terminal to stop the slide relative between said second member and first member.
Compare with one type of prior art syringe, such mechanism is considered to for mistake safer for bumping, and simpler be more convenient for making.In addition, the insertion of first pin does not cause that other terminals open.This also requires also will use pin in this position.
Description of drawings
With reference now to accompanying drawing, only special execution mode of the present invention is described with by way of example, in the accompanying drawings,
Fig. 1 illustrates according to three pin plug of the present invention; And
Fig. 2 illustrates the valve mechanism of the socket shown in Figure 1 in the different running statuses.
Embodiment
As shown in fig. 1, according to the invention provides socket 1, socket 1 is connected to the supply main that is shown in dotted line.Typically, socket is arranged on the wall surface or wall surface of building.Socket 1 has three holes 2 to 4 in the plate in front.The internal terminal that is connected to power ground is aimed in top hole 2, and the terminal that is connected to live wire and zero line is aimed at hole 4 in hole 3.For electrical equipment 5 is connected to power supply, the plug 6 with three pins 7,8 and 9 is aimed at said socket, and pin is inserted and is advanced in the said hole.The action that pin inserts in the hole is operated valve mechanism with the described mode of hereinafter.
Fig. 2 illustrates the intraware of socket 1.In Fig. 2 a, socket has been shown, its cover plate is removed, and intraware is positioned at its initial position before pin insertion of plug.For understanding direction, mark arrow 10 illustrates the position of plug above socket is inserted into the direction the socket.The socket valve mechanism comprises first member 11 and second member 12.
First member 11 comprises three integrated arms 13,14 and 15. Outside arm 13 and 15 comprises door bolt 16 and 17 at its place, end.Inboard arm 14 comprises earth pin inclined plane 18.Along with plug is inserted in the socket along direction 10, earth pin 7 engage angled faces 18 and in the plane of the interarea of socket the direction along arrow 20 promote first member.In the end view of Fig. 2 b, show this action once more with the form of more simplifying.First member 11 is slidably located in the space of material so that smooth and easy moving.Said space is configured to limit as required or retrain said moving.Said move little by little makes ground wire terminal 21 expose to allow and being electrically connected of earth pin 7, shown in Fig. 2 c.
Under the situation shown in Fig. 2 c, will see that door bolt 16 and 17 has moved to the position of the arm that covers second latch member 12.Second member 12 comprises the arm 22 and 23 that relatively extends from horizontal arm 24.Second member is arranged in the recess of cover plate at its initial position, makes in arm 22 and 23 and the laterally inclined end portion 25 and 26 covering zero terminal and fire line terminals 27,28 at the connecting portion place between the arm 24.Second member 12 is installed in the said recess, to have two kinds of possible Move Modes.When mechanism in the state shown in Fig. 2 c, promptly earth pin is inserted and first member 11 and second member when overlapping fully, and first Move Mode takes place.When receiving said overlapping restriction, the insertion of zero line pin and live wire pin 8,9 causes its engage angled face 25 and 26.Insertion has caused second member in the socket plane, to slide, and shown in arrow 29, exposes fully up to zero terminal and fire line terminal, shown in Fig. 2 d.These stages are to allow the correct mode standard operation of inserting of plug.This mechanism has prevented the misuse operation with the described mode of hereinafter.
Fig. 2 e illustrates the situation of misuse.In this case, with the another kind of Move Mode of visible second member 12.In Fig. 2 e, will see not insertion of earth pin, and first member does not have and second member 12 overlapping (yet seeing end view 2f).In this position, member 12 can pivot.This causes arm 22,23 to move up with the door bolt 16 that is resisted against first member and 17 end.Therefore, slide relative motion is prevented from, and zero terminal keeps by inclined plane 25 and 26 coverings with fire line terminal 27,28.Therefore,, this misuse of not inserting earth pin prevented that zero terminal or fire line terminal from being connected in operating.Fig. 2 g illustrates the end view of the non-misuse configuration of corresponding diagram 2c.In this position, slide relative can allow to expose zero terminal and fire line terminal, shown in Fig. 2 d.
Should be appreciated that to be provided with, get back to its initial position when plug is removed, to make valve mechanism such as elastic biasing members such as spring members.These have been omitted for clear.
Under the situation of three pin power supplys the present invention has been described at home.Understand easily, the present invention also will be applicable to the power supply of other kinds or be electrically connected.
