Reference picture 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.A kind of telescopic plug 2, its structure include：One insulator 20, an ejection Part 21, an extensible member 22 and complex root pin 23.

The inside of insulator 20 has a holding tank 201.The insulator 20, which provides, to be carried the ejector 21, stretches The space of part 22 and pin 23, the ejector 21, extensible member 22 and pin 23 is set to be lived in the holding tank 201 It is dynamic.

The ejector 21 is plugged in the insulator 20, and one end is located in the holding tank 201, the other end it is exposed The side of insulator 20.The ejector 21 provides a pressing, promotes the effect of the pin 23, and by interlocking described insert Pin 23 drives the extensible member 22.

The extensible member 22 is located at the holding tank 201, by the ejector 21, and the extensible member 22 is one elastic group Part, the pin 23 is set to be acted on using elastic force and reach flexible effect.

The complex root pin 23 is plugged in the insulator 20, and one end passes through the extensible member 22, is located at the receiving In groove 201, by the ejector 21, the other end is exposed to be located at the side of insulator 20.

The ejector 21 includes a press head 211, an ejection block 212 and a fixed block 213, the press head 211 The insulator 20 is plugged, one end is located at the holding tank 201, and connects and set described one end of ejection block 212, the ejection block 212 Another termination sets the fixed block 213, and described one end of fixed block 213 is arranged the pin 23.

The wall of the holding tank 201 is further provided with a return rail 202, is looped around by the ejection block 212.The pin 23 Side is further provided with a retaining edge 231, and the retaining edge 231 is located between the fixed block 213 and extensible member 22.

The press head 211 provides pressing effect, can be pressed towards the ejection block 212, produce the ejection block 212 Displacement.The rail 202 that returns provides the track that the ejection block 212 moves, and is pressed further towards the fixed block 213. The fixed block 213 is used to promote the pin 23, the pin 23 is stretched out the insulator 20.The retaining edge 231 is used In extensible member 22 described in backstop, the pin 23 is set to be acted on by elastic force and produce retractility.

The telescopic plug 2 further includes the socket 3 that a collocation uses, and the socket 3 includes a cover plate 30 and one and inserted Enter groove 31, the cover plate 30 is provided with an entrance 301, and the insertion groove 31 connects the entrance 301, inside there is a groove hole 311, institute State one conductor wire 4 of the outside of insertion groove 31 connection.

The cover plate 30 is arranged on wall surface, and has the function that the protection insertion groove 31 and plug 2.The entrance 301 provide the passage that the plug 2 passes in and out the insertion groove 31, described to insert so that the plug 2 is inserted in the groove hole 311 Entering has a plurality of patchholes 312 in groove 31, the patchhole 312 connects the groove hole 311 and the conductor wire 4, makes described Pin 23 passes through the patchhole 312 and the conductor wire 4, is electrically connected with the pin 23, and turning circuit.

The cover plate 30 also includes a locking piece 32, and the locking piece 32 is located at the cover plate of relatively described insertion groove 31 30 another side, the locking piece 32 are rotatably provided on the cover plate 30, can conveniently control the position of the locking piece 32.Institute State locking piece 32 and be used for the insulator 20 that backstop is located in the groove hole 311, the insulator 20 is engaging in the groove In hole 311.The cover plate 30 is cover plate made of a fire proofing material.

Reference picture 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.When the insulator 20 enters from the entrance 301, the groove is placed into After in hole 311, using the backstop of locking piece 32 in the entrance 301, it is blocked the path that the insulator 20 exits, and It is scheduled in the groove hole 311, the pin 23 is hidden in the insertion groove 31, prevents accidental shock or using Splash goes out spark in journey, jeopardizes user.When needing to connect circuit, user presses to the press head 211, with described Press head 211 pushes the ejection block 212, after the ejection block 212 is squeezed, can be carried out along the return rail 202 It is mobile, and pressed further towards the fixed block 213, make the fixed block 213 that the pin 23 is released into the holding tank 201, it is exposed outside the insulator 20, so as to penetrate the patchhole 312 through the pin 23, to contact the conductor wire 4, And turning circuit.If by the pin 23 by being extracted on the patchhole 312 and conductor wire 4, user presses institute again Press head 211 is stated, the pin 23 is contracted by the elastic force effect of the extensible member 22 towards the direction of holding tank 201 Enter, and push the fixed block 213 and ejection block 212 in order, the ejection block 212 will move along the return rail 202 It is dynamic, and the press head 211 is backed up into original position, the pin 23 is completely hidden in the described of the insulator 20 In holding tank 201.Due to the effect of the locking piece 32, the insulator 20 is set not made by the elastic force of the extensible member 22 With and eject the groove hole 311, therefore, when the plug 2 be arranged on the socket 3 on after, as long as just can by ejector 21 Control whether turning circuit.The cover plate 30 is made up of fire proofing material, when the situation that electric wire cocks off occurs for plug 2, socket 3, To can surprisingly it minimize.

The utility model is simple in construction, ingenious in design, the advantage is that, by setting a plug with extensible member, uses Person can control pin using pressing mode, pin is had a retractility, and the number of plug plug can be reduced during use, is improved The convenience used, coordinate supporting socket to hide pin, prevent splash from going out spark or accidental shock.

A kind of telescopic plug provided by the utility model is described in detail above.It is used herein specifically Individual example is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help and understands this The method and its core concept of utility model.It should be pointed out that for those skilled in the art, do not departing from On the premise of the utility model principle, some improvement and modification can also be carried out to the utility model, these are improved and modification Fall into the protection domain of the utility model claims.
