Abstract

The present invention relates to a detachable magnetic connector for a cable. The detachable magnetic connector includes a first magnet portion fixed to one end of a cable, and a second magnet portion which is detached from the first magnet portion by a magnetic force. So, it is possible to select a plug corresponding to the specification of the receptacle of a digital terminal and to maximize the convenience of use and reduce unnecessary cost. When a fixing portion and a terminal portion are attached, the second magnet portion of the terminal portion is inserted into the opening of a housing of the fixing portion. So, the terminal portion can be firmly attached to the fixing portion. The connecting pin of the fixing portion is brought into contact with the conductor of the terminal portion when the fixing portion and the terminal portion are attached. Since the conductor is formed of a plate material having an area larger than the turning radii of the connecting pins, the terminal portion is not attached to the fixing portion only in a fixed direction but can be attached to the fixing portion in all directions. So, it is easy to attach and detach.

Description

Removal magnetic connector for cable -

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable magnetic connector for a cable, and more particularly, to a detachable magnetic connector for a cable, which can be used corresponding to various standards of a receptacle of a digital terminal, .

In recent years, with the expansion of the Internet infrastructure and the development of the electronic device industry, the use of portable digital terminals such as smart phones, Bluetooth earphones, tablet PCs and the like is increasing rapidly.

Such a digital terminal generally comprises a receptacle for receiving power from an external power supply adapter or for transmitting and receiving data signals to and from an external electronic device, wherein a receptacle of the digital terminal is provided with a plug of a charging cable or a data cable So that they can receive power or transmit / receive data signals.

That is, when a digital terminal is purchased, a user purchases a charging cable and a signal cable together with a plug corresponding to the receptacle of the digital terminal, and performs charging and data transfer functions.

Although the receptacle of such a digital terminal may have the same specification only for the same manufacturer, since specifications of shape and size vary according to the number of manufacturers, products, pins, and the like, The charging cable and the signal cable provided with the plug corresponding to the standard need to be separately purchased, which leads to a disadvantage that not only the convenience of use is reduced but also unnecessary cost is consumed.

In addition, even when the plug and receptacle are connected and disconnected in the related art, there is a problem that the connecting portion of the receptacle is damaged by the force generated by the side portion when the plug and the receptacle are connected and disconnected, or the connecting portion is worn and damaged or the shape of the plug is deformed And thus the connection failure frequently occurs.

In addition, even if plugs and receptacles are conventionally connected, since the coupling is supported only by the recesses and projections of the plug and the receptacle, the coupling is frequently released by a small external force.

In order to solve such a problem, various studies have been made on a magnetic connector for increasing the coupling between the plug and the receptacle by using magnetism.
