Abstract

The utility model discloses a dual-purpose plug comprising a plug housing, a plurality of pins, a wire, a plurality of plug holes arranged on the plug housing, a socket housing, and another wire connecting the plug housing with the socket housing; the plurality of plug holes are arranged on the socket housing, and the socket housing can be detachably connected with the plug housing. By employing the structure, when the socket is not sufficient, the dual-purpose plug can serve the socket function, especially when a plug plugging into the dual-purpose plug is not long enough, then the socket housing can be separated from the plug housing, and the other wire originally contacted in the socket housing can be pulled out to satisfy length requirement, so usage is more flexible. When the plug plugging into the dual-purpose plug is long enough, the other wire needs not to be pulled out for prolonging the socket housing, so the socket housing can be fixed on the plug housing, thereby saving space.

Description

Dual-purpose plug

Technical field

The utility model relates to a kind of plug, particularly a dual-purpose plug with function of socket.

Background technology

At present, pin function general on market is all more single, only for being connected to other electric power supply with socket.In daily life, often occur that socket has stuck with, some plug can be inserted nowhere and have to use the phenomenon of wiring board.

Chinese patent specification CN201113100Y discloses a kind of dual-purpose plug, it has solved the problem of ordinary plug function singleness, it sets up jack on an ordinary plug, makes when many electrical equipment needs socket simultaneously, and a fixed socket can be simultaneously for a plurality of plugs.

Yet, in reality is used, because the set jack system of above-mentioned dual-purpose plug is set directly on plug casing and position is fixed, when the electrical equipment of required power supply cannot move and when power line falls short of again, the jack being positioned on described dual-purpose plug cannot play a role, and performs practically no function.

In view of this, the utility model provides a kind of dual-purpose plug, and jack set on it can move relative to plug casing, uses more flexible.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of use dual-purpose plug more flexibly, and jack set on it can move relative to plug casing.

For solving the problems of the technologies described above, dual-purpose plug of the present utility model, comprises a plug casing, several pins, one first wire, a Socket casing and several jacks, and one second wire.Described the first wire is extended by plug casing, described several jacks are located at the above second wire of Socket casing and are connected between described plug casing and Socket casing, when described Socket casing is fixed on described plug casing, described the second wire shrinks in described Socket casing, when described Socket casing is separated from described plug casing, described the second wire stretches out described Socket casing.

Described Socket casing is provided with described card and establishes groove quantity and latch corresponding to shape, and described latch inserts or departs from described card establishes groove.

Use such plug, owing to being arranged on described the second wire between Socket casing and plug casing, relative described plug casing is capable of expansion and contraction as required, thereby in the time need to inserting the plug of the utility model jack and fall short of, pull out Socket casing, the wire connecting will stretch out Socket casing, meet length needs, and when plug length is enough, described the second wire is contained in Socket casing, and Socket casing is fixed on plug casing, uses more flexible.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is the dual-purpose plug receptacle housings of the utility model use view separated with plug casing.

Fig. 2 is that the dual-purpose plug receptacle housings of the utility model is fixed on and on plug casing, uses view.

Fig. 3 is the utility model plug casing front view.

Fig. 4 is the utility model Socket casing front view.

Embodiment

Fig. 1-2 is depicted as dual-purpose plug one preferred embodiment of the utility model.In the present embodiment, described dual-purpose plug comprises plug casing 1, three pin 2, one first wire 3, one second wires 4, and a Socket casing 5.

Described plug casing 1 one side is provided with above-mentioned three pins 2, offers card and establishes groove 12, as shown in Figure 3 with opposite face.Shape and quantity that described card is established groove are not restricted, and the quantity of establishing groove 12 in card described in the present embodiment is one.

Described the first wire 3 and the second wire 4 are extended by described plug casing 1 respectively and are electrically connected with described three pins 3.Described the first wire 3 can be the power line of electrical equipment or the power line of multipurpose socket, and in the present embodiment, the power line of electrical equipment of take is example.Described the second wire 4 is connected with described Socket casing 5, and described the second wire 4 telescopicallies are contained in Socket casing 5.It should be noted that the flexible system due to the second wire 4 described in the utility model realizes by known techniques, therefore be not described further at this.

Quantity and form that described Socket casing 5 is provided with jack 51 described in jack 51 and latch 52. and latch 52 respectively at two opposite faces are set as required, in the present embodiment, as shown in Figure 4, the quantity of described jack 51 is three, and its form is set to plug for common triangle plug.In the present embodiment, to establish the quantity of groove 12 identical with being arranged at card on plug casing 1 for the quantity of described latch 52, and that their structure and described card are established groove 12 structures is corresponding, make described latch 52 to establish groove 12 with described card and closely cooperate, thereby described Socket casing 5 is fixed on plug casing 1.It should be noted that in this other embodiment and also can take alternate manner that Socket casing 5 is fixed on plug casing 1, be not limited to the fixed form of the present embodiment.

Be more than the simple introduction of element of the present utility model and interelement structural relation, below again in conjunction with diagram 1-2, further understand function of the present utility model and beneficial effect.

Referenced in schematic 1, it has shown the utility model the first use state, in the time will using, user can insert the pin on plug casing 1 described in the utility model 2 in a common socket, the electrical equipment normal power-up work being connected with described the first wire 3, and now described Socket casing 5 is fixed on described plug casing 1 by latch set on it 52, and described the second wire 4 shrinks in described Socket casing 5.Under this kind of use state, the sufficiently long electrical equipment of another power line can insert the jack 51 on Socket casing 5 of the present utility model and switch on.

Referenced in schematic 2, it has shown that the utility model the second is used state, under this kind of use state, the card that latch 52 on described Socket casing 5 departs from described plug casing 1 is established groove 12, described Socket casing 5 is departed from from plug casing 1, now, described the second wire 4 is along with the movement of Socket casing 5 is drawn out Socket casing 5.Under use state, position electrical equipment fixing and that power line length falls short of can insert the jack 51 on Socket casing 5 of the present utility model and switch at this moment.

As can be seen here, use of the present utility model is more flexible, facilitates user to use at different situations down conversion, and when when pulling out described the second wire 4, described the second wire 4 can be shunk in described plug casing 1, can save space.

In sum, the various embodiments described above and diagram are only the preferred embodiment of the utility model, when can not with the scope of restriction the utility model enforcement, the equalization of generally being done according to the utility model claim changes and modifies, and all should belong in the scope that the utility model patent contains.
