Description

Portable soft socket

technical field

The invention relates to a power strip, in particular to a portable soft power strip.

Background technique

It can be seen from the current technology that a general socket is usually provided with a plug, a socket, and a power cord connected between the plug and the socket (as shown in Figure 1). It is composed of electrical components such as chips, and there are several groups of jacks on the insulating shell for plugging other electrical appliances into it to supply power to other electrical appliances. The existing plug-and-socket structure manufacturing technology is quite mature, widely used in various occasions, and has become one of the indispensable electrical equipment in places such as homes and offices.

However, the existing socket structure has the following disadvantages:

1. The existing commonly used row and socket structure is to install all groups of conductive sheets in the socket in the same insulating shell, so the insulating shell is relatively large in size, which makes it very inconvenient to carry, and is rarely used for carrying use. However, in many public places, such as school libraries, classrooms, etc., the number of fixed sockets on the wall is limited, which cannot meet the needs, so it is necessary to carry a power strip.

2. On the other hand, the position of each set of jacks on the insulating housing is fixed. In order to save space, the distance between each set of jacks is limited, and the plugs of various electrical appliances have various shapes. The phenomenon of mutual interference between the plugs leads to unreliable insertion, and even larger plugs will affect the use of adjacent jacks.

3. Furthermore, due to the large insulating shell of the existing structure of the row slots, too much plastic and other insulating materials are used to produce such row plugs. For producers, the manufacturing cost will be high in the long run and uneconomical The principle of production.

Contents of the invention

The technical problem to be solved by the present invention is to provide a portable soft socket which is small in size and does not interfere with each other.

Preferably, each terminal power cord on each socket is directly led out from the plug.

Preferably, at least two branch power lines are directly led out from the plug, and each branch power line is provided with one of the sockets, that is, each end power line of the socket is branched from the branch power line.

Preferably, a main power line is directly led out from the plug, and at least two branch power lines are branched out from the main power line, and each branch power line is provided with one of the sockets.

Preferably, a branching hub is provided at the bifurcation of the main power line and the branch power lines.

Preferably, a branching hub is provided at the bifurcation of the branch power cord and the terminal power cord.

Preferably, a fuse is arranged inside the distribution hub.

Preferably, a control switch for controlling the on-off of the corresponding socket is provided on the branch power line or at the bifurcation of the branch power line and the branched end power lines.

Preferably, the main power supply line is provided with a control switch for controlling the on-off of the corresponding socket.

Preferably, the distribution hub is provided with a control switch for controlling the on-off of the corresponding socket.

Preferably, the flexible socket further includes a transformer electrically connected to each pin of the plug, and the transformer is connected to the USB socket or/and the mobile phone charger interface; the transformer is directly arranged in the plug or further connected to the plug. A branch power line is branched out, and the transformer is arranged on the branch power line.

After adopting the above scheme, the present invention has the following beneficial effects:

1. The invention has completely changed the structure of the traditional plug-and-socket, so that each jack of the socket in the plug-and-socket is completely separated from the traditional plug-and-socket, and each jack is connected by a soft power cord, so that free connection can be realized, greatly The size is reduced, and the soft wire-like structure is very convenient to carry.

2. Since the sockets of each socket in the socket are relatively independent and are connected with movable soft power cords, the sockets will not interfere with each other, so there will be no situation where the inserted plugs will not be affected by each other. , and there will be no problem that larger plugs affect the use of adjacent sockets.

3. The size of each jack insulating shell of the socket outlet of the present invention usually only needs to be made into a size that can accommodate a conductive piece, so the amount of insulating material used for the socket socket can be saved to the greatest extent, and the cost can be greatly reduced.

In a word, the present invention subversively changes the structure of the traditional power strip, which not only greatly reduces the volume, but also greatly saves the amount of insulating material, and can be easily connected regardless of the two-hole or three-hole plug, which is a must-have choice for business trips .

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted here that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

What the present invention discloses is a portable soft socket, as shown in FIG. 2 , which is the first preferred embodiment of the present invention. The flexible socket includes a plug 1 and at least one socket S, each socket S includes two or three terminal power cords 2, each terminal power cord 2 is electrically connected to each pin 11 of the plug 1, and each terminal power supply The wires 2 are independent of each other; an insulating shell 3 is arranged at the end of each terminal power line 2, and a conductive sheet 4 electrically connected to the connected terminal power line 2 is fixed inside the insulating shell 3, and each insulated The housing 3 is also provided with an insertion hole 31 .

During use, insert the jack 31 of the insulating housing 3 on each terminal power line 2 to the corresponding pin of the plug of the electrical appliance to be powered, that is, the electrical connection between the conductive sheet 4 in the jack 31 and the plug pin can be realized, thereby Power electrical appliances.

Each terminal power cord 2 on each socket S can be directly drawn out from the plug 1, as shown in the above-mentioned first embodiment, but for a flexible socket with only one socket S, in fact, only It is a power extension cord, which has no practical significance and is only used to illustrate the basic features of the present invention. And for having a plurality of sockets S, the end power line of each socket is all drawn from the structure of plug 1, although it can be realized, it is difficult for the user to distinguish which lines can be combined into one socket, so it is not convenient enough to use. Solved by the following solutions.

As shown in Figure 3, it is the second embodiment of the present invention. The flexible power strip described in this embodiment includes a plug 1 and at least two branch power lines 5 directly drawn from the plug 1, each branch power line 5 Each is provided with a said socket S.
