A plug includes a plug housing and a metal terminal group. The metal terminal group includes a mating electrode group on the first end side thereof and a connection electrode group on the second end side, the mating electrode group including mating electrode sections that are disposed with an insulating resin interposed therebetween and are to be in contact with the contacts of a mating jack, the connection electrode group including connection electrode sections that are disposed with an insulating resin interposed therebetween and are connected to the electrodes of a connection member. The mating electrode sections are disposed coaxially with an axis P of the plug, and at least two of the connection electrode sections are disposed around the axis P so as to surround the axis P side by side.

Plug

The present invention provides a co-axial connector for a high frequency cable which includes a slit in the earth metal fittings. The slit enables the earth metal fittings to be widened and allows insertion of an insulating bushing into the earth metal fittings. After insertion, the slit returns to its home position by the spring tension of the earth metal fittings and retains the insulating bushing by spring tension. This configuration makes assembly easier. Furthermore, after the insertion of the insulating bushing into the earth metal fitting, a shielding cylinder is engaged with the earth metal fittings in order to cover the rear end of the earth metal fittings. This configuration prevents high-frequency signals from leaking, and does not require the widening of the slit, while connected to the other connectors, which loosens the engagement between the earth metal fittings and the insulating bushing. Consequently, this configuration of the present invention prevents the insulating bushing from slipping off.

Co-axial connector for high-frequency cable

A cable connector includes a plug for connecting a coaxial cable to an electronic device such as a television or video cassette recorder. The plug includes a sleeve that connects with a first grounding terminal of a receptacle. An outer diameter of the sleeve is dimensioned to provide a good unstressed interference fit with the first grounding terminal. The sleeve has slits in a portion to permit elastic deformation when connecting with a second grounding terminal having an inner diameter less than that of the first grounding terminal. These slits permit the sleeve to compress sufficiently to form an interference fit inside the second grounding terminal. When both the first grounding terminal of the receptacle and the sleeve of the plug are dimensioned for the format, and the second grounding terminal is dimensioned for the SECAM format, the plug fits either grounding terminal.

RF separator

A balun transformer with a common mode coil is formed by parallel two-strand cable wound around a common core having through-holes through which the cable passes. The common mode coil can be connected either on the input side or the output side of the balun transformer. Because only one core is used to form both the balun transformer and the common mode coil, the outer dimensions of the transformer can be reached, along with manufacturing costs, to reduce the number of man-hours required to manufacture the transformer by this invention. This configuration also permits shorter connections between the balun transformer and the common mode coil.
