Abstract

The utility model provides an expandable power socket, composed of a socket body and an expanding module which are all provided with fixed devices matched with each other, such that the socket body can be fixedly connected with the expanding module in a detachable manner. The socket body can be used as a power socket alone, furthermore, the socket body can be expanded by connecting the expanding module without limit.

Description

But a kind of expansion of power supply socket
Technical field
The utility model relates to a kind of electrical installation, particularly a kind of extendible supply socket.
Background technology
Traditional supply socket generally is made of lead, jack body.Consider that socket may need to be a plurality of electrical appliance power supplies, the user often needs one a plurality of jacks are provided above the socket.The jack that the supply socket of Chu Shouing in the market is generally more than two is fixedly set in above the jack body.Though this design has solved the problem of powering for a plurality of electrical appliances simultaneously,, its shortcoming is very tangible.
At first, this electrical socket causes the waste of resource easily.Do not need to connect what electrical appliances owing to do not know for sure in advance, therefore, the user often wishes that the jack units of buying is The more the better when buying porous socket.And the many sockets of jack units must need more materials to make, and also must be asked for higher price.Under the few situation of user power utilization device, it is idle that porous socket often has a large amount of jacks, causes waste.
Secondly, this electrical socket can't expand.Often see such sight in the reality, because the receptacle sockets of buying is on the low side in advance, user's electrical appliance can't insert simultaneously and reach electricity in the socket, thereby causes great inconvenience to the user.
For these reasons, press for a kind of electrical socket that can expand, with the problem that solves the wasting of resources of traditional electrical socket and can't expand.
The utility model content
In order to address the above problem, the utility model provides a kind of and expands to adapt to the electrical socket of multiple spot power supply, and the technical solution of the utility model is as follows:
But a kind of expansion of power supply socket, it is characterized in that: form by jack body and expansion module, described jack body has the lead that is used to connect external power source, described expansion module is provided with jack, described jack body is electrically connected by hard contact with described expansion module, and by being arranged at dismountable the fixedlying connected of fixture on described jack body and the described expansion module respectively.
Described expansion module also is provided with the fixture of expanding connection for the next stage expansion module, and promptly expansion module can be by tapping into capable unlimited extension under the fixture first line of a couplet that is provided with on it.
Described jack body comprises with fixture on the described expansion module and is arranged at described jack body and mutual corresponding projection and groove above the described expansion module respectively.
Described fixture also comprises pin or the axle that the projection of the connection that is complementary is fixedlyed connected with groove.
Described jack body is provided with the jack for the external plug power taking, can independently use as electrical socket.
Described expansion module is provided with voltage changer and voltage indication means.
Described expansion module can comprise a plurality of expansion modules, and wherein the voltage changer in each expansion module can have different voltage transformating ratios, to export different voltage.
Described expansion module is provided with switching device.
Described expansion module is provided with the indicator light that is used to indicate current "on" position.
Described expansion module is provided with the current overload protection protection unit.
Technique effect of the present utility model is:
By expansion module is set, and utilize hard contact to be electrically connected expansion module and the jack body, utilize the dismountable fixed connection apparatus that is separately positioned on jack body and the expansion module simultaneously, make people when needs expand the jack of jack body, can very simple expansion module be installed on the jack body, expansion module can provide new jack to use for the user.
Expansion module of the present utility model can also be realized expansion once more by the fixed connection apparatus that is provided with, and connects under the first line of a couplet by expansion module, can realize the infinite expanding of expansion module.
And, also be provided with voltage changer on the expansion module, making can provide different voltage jacks to select use for the user after the electrical socket of the present utility model expansion.
Furtherly, can under the prerequisite of a jack body,, just can obtain the effect of a socket multiple voltage output by mating a plurality of expansion modules with different voltage transformation ratios.
In sum, the utility model not only can improve the quantity of the power supply jack of socket, and different voltage output can be provided, and also has the effect that improves the socket effective utilization, reduces material consumption.
Description of drawings
But Figure 1 shows that the structural representation of the utility model expansion of power supply socket.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
But Figure 1 shows that the structural representation of expansion of power supply socket of the present utility model.
But expansion of power supply socket of the present utility model comprises jack body 1, comprises lead 4 and plug 3 on the jack body 1, includes one group of jack 11 on the jack body 1, and switch 12 and circuit indicator 13, and jack body 1 can independently use as electric socket.
Jack body 1 is provided with the location notch 14 of the expansion module that is used to peg graft and is electrically connected hole 15
Include one group of jack 21 on the expansion module 2, and switch 22 and circuit indicator 23, expansion module 2 be provided with jack body 1 on location notch 14 location lug 24 and the conduction connection-peg 25 that are complementary.
The side of the location notch 14 of jack body 1 is provided with pin-and-hole 16, when expansion module 2 and jack body 1 are expanded when being connected, after pegging graft mutually between electrical connection hole 15 and conduction connection-peg 25, location notch 14 and the location lug 24, in pin-and-hole 16, insert steady pin, can guarantee accurate positioning between expansion module 2 and the jack body 1, install firmly, and be convenient to very much dismounting.
Certainly, location notch 14 shown in 1 and location lug 24 its cross sections are square, in fact, also can adopt one group of circular hole and cylinder as positioner, or the projection of other mutual coupling and groove structure, for example dovetail and oat tail groove structure or the like.
At the opposite side of expansion module 2, also be provided with location notch 14, pin-and-hole 16 and be electrically connected hole 15, be connected so that expand with the next stage expansion module, according to same mode, each grade expansion module all can be expanded downwards, thus the purpose of realization infinite expanding.
Also be provided with voltage conversion circuit in the expansion module 2, utilize voltage conversion circuit, can in the jack 21 of expansion module 2, export different voltage.
But extension socket of the present utility model both can a jack body correspondence dispose a kind of expansion module, also can dispose a plurality of expansion modules with different voltages outputs, can provide multiple choices to the user.
The above only is a preferred implementation of the present utility model; but according to spirit of the present utility model and essence; can also improve on this basis and change, but any improvement and variation that does not break away from the present utility model essence all should be contained into protection range of the present utility model.
