Description

[Detailed description of the invention] This invention maintains the corresponding parts of the circuits in the housings in which the corresponding electric circuits are installed, and connects them to the boundary parts of the adjacent housings. The present invention relates to a connector that is arranged and rotatable around a rotation axis common to adjacent casings.

Each electrical circuit is attached to the boundary between the casings, which are arranged adjacent to each other so as to be rotatable around a common rotation axis, and the necessary parts of the electrical circuit of each casing are electrically connected. There is a need for a connector that can be assembled and used so as to maintain the state connected to the two housings and to be rotatable around the rotation axis of each housing. For example, in a portable stereo device, the left and right speakers and the related circuitry corresponding to each speaker are installed in separate casings, and these two casings can be rotated around a common rotation axis. When in use, the two casings are open around the rotation axis, and when carried, the casings are closed together around the rotation axis, making the whole smaller as needed. By making it possible to make the stereo device more convenient to use and carry, a stereo device with a shape that is extremely convenient to use and carry can be obtained.

This device is used in such cases, and can be used by being attached to the common rotation shaft of each case that is placed adjacent to each other, and can be attached to each case at each rotation position of the case. The present invention provides a connector that is rotatable while the corresponding parts of the circuits are electrically connected to each other.

According to this invention, a plurality of first and second containers are disposed protruding from the first and second bases in parallel with each other with their tip positions aligned, and these first and second containers A plurality of first and second mounting grooves are formed on the side surfaces of the housing in the arrangement direction thereof, passing through the first and second bases, respectively. The first and second contacts are accommodated in the first and second mounting grooves, respectively, and the contact portion formed on the end side of the contact when accommodated is connected to the first and second contacts on the tip side of the housing body. The first and second contacts are received in the first and second mounting grooves, respectively, being resiliently biased at right angles to respective sides of the second housing.

In this invention, a second housing body is arranged between adjacent first housing bodies each housing a first contact in a first mounting groove, and a second housing body housing a second contact housing each in a second mounting groove. The contact portions of the first and second contacts facing each other are electrically connected to each other while the contacts are disposed so as to be engaged with each other.
