Description

Separate type multi-tap

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-tap, and more particularly, to a separate multi-tap capable of separating and coupling between a main multi-tap and a sub-multi-tap or sub-

Generally, the multi-tab is a tab used for simultaneously using a plurality of electronic devices as one tab having a plurality of connection ports to which plugs of an electronic device are connected. Such a multi-tab takes the form of an elongated bar when a plurality of connection ports are arranged in a line.

In the case of an elongated multi-tap, since the length of the multi-tap is also increased as the number of the connection ports is increased, it can be used with a large space occupied in a home or office space and inconvenience to the user. For example, an elongated multi-tap may be a car on the feet of passers-by, and unnecessarily occupies a lot of space in cleaning, which may cause inconvenience in handling.

In addition, if a plug is connected to all of the connection ports provided in the multi-tap and a plug is connected only to a part of the connection ports, and a large number of unused connection ports are left, a discomfort due to the long length of the multi- The problem becomes even bigger.

In particular, since the multi-tap according to the related art is integrally formed, one multi-tap can be used only in one place. For example, when the desks are arranged in a row or in a "? &Quot; shape, the electronic devices disposed on one side are connected to one multi-tap, and the electronic devices disposed on the other side are connected to another multi-tap for power connection. In this case, there is a problem in that it requires a lot of multi-tabs, which is costly and the power connection becomes complicated.

Also, in the case of a conventional multi-tap, it is composed of several connection ports and they are integrally formed into one. If the multi-tap is saturated, a new multi-tap purchase is required, which is very inefficient in terms of cost or interior. On the other hand, it can be used in a condition where the unsaturated state is maintained by purchasing a multi tap which has a sufficient connection port, but there is a great risk of a safety accident due to dust accumulation on the unused multi tap connection port or exposure.

In addition, since each of the connection ports is formed as a whole, one failure is required to be replaced, not a repair, because it leads to an entire failure. This shows that current multi-tap is very vulnerable to failures.

Also, the type of multi-tap shown on the market is limited to a linear or diamond shape. This geometrical limitation is very inefficient in the installation of multi-tabs in an office having a narrow structure or an ordinary household.
