Description

The present invention relates to a connector capable of endlessly connecting or disconnecting an accessory chain having a decorative material such as a jewel or the like using a magnet.

Generally, chains such as necklaces and bracelets are endlessly attached to parts of the body such as the neck and arms, but in the past, it was necessary to hook and connect the hooks provided on the back, and there was only one user. It took time and effort to operate with.
On the other hand, as a structure using magnets for attaching and detaching chains of accessories, for example, in Japanese Patent Application Laid-Open No. 2010-233701, in the first and second magnets magnetized and coated so that the north and south poles appear alternately in a plane. , The magnets in which the first and second magnets are attracted so as to be in contact with each other and the first and second magnets are connected to a surface different from the surface of the first and second magnets related to the contact. It has a structure including a chain connector.
However, in the above configuration, even if the N-pole and S-pole magnets are magnetized, the magnetic force is easily impaired if a force is applied in a direction substantially parallel to the magnetized surface, and the magnets may be peeled off.
Further, the connector for a fitting of Japanese Patent Application Laid-Open No. 2007-222301 is a connecting tool that is attached to both ends of the fitting and connects the fitting in an endless manner, and is a first connection attached to one end and the other end of the fitting, respectively. It is composed of a portion and a second connecting portion, and the first connecting portion and the second connecting portion form a single hollow housing, respectively, in the outer peripheral direction at an intermediate portion in the connecting direction between the first connecting portion and the second connecting portion. It has a first housing and a second housing having a shape cut along a straight line or a curved line having irregularities on the surface, and permanent magnets are fixed in the first housing and the second housing, respectively. Is magnetized so that one of both ends in the direction orthogonal to the connecting direction is the N pole and the other is the S pole, and the first housing and the second housing are fixed in each housing. It is characterized in that the hollow housing is formed at a connecting position where the different poles of the permanent magnets are opposed to each other.
With the above configuration, even if a force is applied in the direction parallel to the magnetized surface of the permanent magnet, the magnetic surface is constrained by the fitting of the first connecting portion and the second connecting portion, so that the magnetized surface does not come off. However, there is a problem that the structure becomes complicated and it is difficult to miniaturize.
