Embodiment
In the following description, by the numerous embodiments of apparatus of the present invention, use similar Ref. No. to describe similar concept.Such as, Ref. No. 110 and 210 will be used in reference to joint of the present invention.
Fig. 1 illustrates joint 110 of the present invention in a schematic way.Joint comprises housing or main body 112, and it corresponds to usually by the part of user operation.The cable 150 with insulating case 152 is attached with housing 112.Cable corresponds to the power cable of 230V usually, and according to known, it comprises phase conductor 121, neutral conductor 131 and the conductor 141 for being connected zero potential (ground connection).Three conductors respectively by insulating case 122,132,142 around.Situation shown in Fig. 1 corresponds to the situation that joint normally runs.Jockey 120,130,140 set up the connection between cable conductors 121,131 and 141 and the corresponding contact pilotage of joint or contact 123,133 and 143.Contact 123 corresponds to phase contact, and contact 133 corresponds to neutral contact, and contact 143 corresponds to earthing contact.Preferably, each contact comprises receiving system 126,136,146, its for when assembling joint by conductor 121,131,141 are fixed on contact 123,133,143.Usually, joint 110 of the present invention may correspond in plug or joint.
The feature of this joint is, it comprises at least one release mechanism, its objective is when not having power-off in advance, prevents conductor 121,131,141 under voltage from connecting air.In fact, when joint connects equipment or power distribution network, conductor 121 and 131 is electrical current carriers.When unexpected or when having a mind to apply pulling force 160 in cable 150, conductor can be caused to connect air, and this can bring the danger producing short circuit.
In the example of fig. 1, release mechanism is arranged to, and under the effect applying pulling force 160, first conductor 121 and 131 disconnects, and earthing conductor 141 disconnects subsequently.By arranging pre-programmed discontinuity area 124 respectively on phase conductor and neutral conductor, 134 realize this point.Such as, the feature of pre-programmed discontinuity area 124,134 can be, has the conductor segment of cross section reduction relative to its conventional cross section.When applying pulling force to such conductor, described cross section reduces section and first stops (c é der), to interrupt electrical contact in a controlled manner.
Under acting at pulling force 160, earthing conductor 141 finally disconnects, and conductor 141 arranges extension 145.Therefore conductor 141 in the housing heart portion, cable 150 export the length between being connected with its electric shock 143 than phase conductor and neutral conductor longer.First, prolongation 145 can absorb pulling force effect at least partially.During this period of time, phase conductor jockey and neutral conductor jockey disconnect with respective conductor.Situation when applying after pulling force or apply pulling force is illustrated by Fig. 2.When conductor 121 and 131 disconnects under a stretching force, earthing conductor 141 is tightened up, but still keeps connecting.The application applied after pulling force will disconnect earthing conductor equally.
Advantageously, the insulating case 122,132,142 of at least insulating case 152 of cable, and/or wire such as can be attached to housing 112 by welding.This configuration ensures that the continuous disconnection when pulling cable.Because insulating case is fixed on housing, metallic conductor can move in its insulating case separately.First, rigid phase conductor and neutral conductor disconnect.Then, after utilizing its reserved displacement, disconnect rigidity earthing conductor.Finally, flexible insulation cover steps down (c é der).Now, all electrical connections are interrupted automatically, greatly reduce security risk with this.
Execution mode as an alternative or described by improving, the cross section of phase metallic conductor 121 and neutral conductor 131 is less than the cross section of ground metal conductors 141.Therefore conductor is resisted usually than phase conductor and the larger pulling force of neutral conductor.
In another embodiment, described release mechanism can also be supplemented with the fixing respectively of neutral conductor 131 by the phase conductor 121 that fixedly makes relative to earthing conductor.Such as, phase conductor 121 and neutral conductor 131 are fixed by the assembling mode of crimping sleeve and the receiving system 126,136 of respective contact 123,133.This assembling sets up necessary connection by the deformation of material.Earthing conductor 141 is connected with the receiving system 146 of earthing contact 143 by welding assembly, and this is firmer than crimping sleeve.By this way, pre-programmed discontinuity area 124,134 can be performed when assembling joint connects.
Fig. 3 schematically shows another execution mode of joint of the present invention.This joint comprises housing or main body 212, and it corresponds to usually by the part of user operation.The cable 250 with insulating case 252 is attached with housing 212.This cable corresponds to the power cable of 230V usually, and comprises phase conductor 221 by known, neutral conductor 231 and the conductor 241 for being connected zero potential (ground connection).Three conductors respectively by insulating case 222,232,242 around.Situation shown in Fig. 3 corresponds to the situation that joint normally runs.Jockey 220,230,240 set up the connection between cable conductors 221,231 and 241 and the corresponding contact pilotage of joint or contact 223,233 and 243.Contact 223 corresponds to phase contact, and contact 233 corresponds to neutral contact, and contact 243 corresponds to earthing contact.Preferably, each contact comprises receiving system 226,236,246, its for when assembling joint by conductor 221,231,241 are fixed on contact 223,233,243.Usually, joint 210 of the present invention may correspond in plug or electric connection.
It is shown and to describe that the release mechanism relating to earthing conductor is similar to Fig. 1 and Fig. 2.The pre-programmed discontinuity area 224,234 of the jockey 220,230 of phase conductor and neutral conductor is performed by least one switch, when joint can operate, and closing switch.As shown in Figure 3, cable 250 can comprise additional wire 271, and it is connected with at least one switch, when applying pulling force 260 to cable, to open this switch.By this way, the electrical connection of phase conductor and neutral conductor disconnects immediately in an automatic fashion.
