Description

Two-way coaxial plug and manufacturing method thereof {TWO-WAY COAXIAL PLUG AND MANUFACTURING METHOD THEROF}

The present invention relates to a two-way coaxial plug and a method of manufacturing the same, and more specifically, to a two-way coaxial plug capable of both straight and inclined coupling and a method of manufacturing the same.

The array connector of the prior art is configured to allow contact only in a designated direction. In other words, most array connectors can only be connected in a straight line. In addition, as an applicable range, there are cases where the connector is combined at 90 degrees depending on the cable connection position. However, connectors fixed in one direction cannot be combined in multiple directions. In some cases, fluid diverges into a multi-directional connector, as in the related technique below.

When a conventional connector with one end and the other end fixed in a straight line connects two points on the same plane, the cable connected to the connector connected to the two points has no choice but to form a circular orbit, so the length of the cable is inevitably long. In the case of RF coaxial cables that process high-frequency signals, there may be a problem of reduced output due to the resistance of the conductors.

As a technology related to the present invention, the improved three-way connector disclosed in the Korean Patent Publication discloses a three-way connector as a configuration having an open end and a closed end, but as a connector connected to a pipe through which fluid passes. As a coaxial cable connector that connects electronic components, especially RF devices, in that it cannot be connected in multiple directions, the purpose, configuration, and effects of the present invention are different from the present invention that allows RF devices to be connected in two directions using a coaxial cable.
