Description

다극용 플러그 및 잭{Multi-terminal plug and jack}Multi-terminal plug and jack

본 발명은 다극용 플러그 및 잭에 관한 것으로서, 더욱 상세하게는 다수개의 접촉단자를 가진 다극용 플러그 및 잭이 핸드폰, 소형카셋트플레이어와 같은 소형전자제품에 사용되어 복잡하고 다양한 원격제어가 가능하도록 한 플러그 및 잭에 관한 것이다.The present invention relates to a multi-pole plug and jack, and more particularly, a multi-pole plug and jack having a plurality of contact terminals are used in small electronic products such as mobile phones and small cassette players to enable complex and diverse remote control. Relates to a plug and a jack.

도 1a는 종래기술에 의한 다극용 플러그의 정면도이고, 도 1b는 종래기술에 의한 다극용 플러그의 정단면도이다.1A is a front view of a multipole plug according to the prior art, and FIG. 1B is a front sectional view of a multipole plug according to the prior art.

일반적으로 원격제어장치가 구비되도록 하기 위한 종래의 다극용 플러그(100)는 플러그(100)에 환형의 접촉링(103)을 절연체(102)로 각 접촉링(103)을 전기적으로 절연하여 다수개 적층하고, 상기 접촉링(103)에 상응하도록 잭에 접촉단자를 구성하였다.In general, a multi-pole plug 100 for providing a remote control device is electrically insulated from each contact ring 103 by an insulator 102 with an annular contact ring 103 on the plug 100. The contact terminal was configured in the jack so as to correspond to the contact ring 103.

그러나 상기와 같은 기존의 다극용 플러그(100)는 플러그(100)의 길이에 한계가 있어서 접촉링(103)을 구성할 수 있는 단자의 수에 한계가 있었으며, 이를 해결하기 위해 별도의 제2플러그등을 구성하여 접촉단자의 수를 늘렸으나 이는 플러그 및 잭의 크기가 커져서 소형화되어 가는 전자제품에 사용하기에는 많은 불편함이 있었다.However, the conventional multi-pole plug 100 as described above has a limit in the length of the plug 100 has a limit on the number of terminals constituting the contact ring 103, in order to solve this, a separate second plug Although the number of contact terminals is increased by configuring a back, it has been inconvenient for use in electronic products that are miniaturized due to the increase in the size of plugs and jacks.

또한 접촉링(103)을 가진 종래의 플러그(100)는 잭에 삽입되었을 때 플러그(100)가 회전하면서 접촉불량으로 인한 노이즈 현상 및 공명현상이 발생하는 등의 문제점을 가지고 있었다.In addition, the conventional plug 100 having the contact ring 103 has problems such as noise phenomenon and resonance phenomenon caused by poor contact while the plug 100 rotates when inserted into the jack.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 잭에 삽입되는 플러그의 원통외주면에 원통의 종방향으로 다수개의 접촉단자가 절연체와 번갈아가며 구성되고, 플러그가 삽입되는 잭의 원통형의 내주면에는 플러그가 삽입되는 방향으로 장방형의 접촉단자가 구성되어 플러그가 삽입되었을때 플러그와 잭의 접촉단자들이 서로 각각 접촉할 수 있도록 함으로서 플러그의 길이와 상관없이 하나의 플러그만으로 많은 수의 접촉단자를 제공함으로서 기존의 다극용 플러그보다 크기가 작고 많은 수의 접촉단자를 가지는 소형의 다극용 플러그 및 잭을 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is a plurality of contact terminals in the longitudinal direction of the cylinder alternately with the insulator in the cylindrical outer peripheral surface of the plug to be inserted into the jack, the plug of the jack The cylindrical inner circumferential surface has a rectangular contact terminal in the direction of inserting the plug so that when the plug is inserted, the contact terminals of the plug and the jack can contact each other, so that a large number of contacts can be made with only one plug regardless of the plug length. Providing a terminal provides a small multi-pole plug and jack having a smaller size than a conventional multi-pole plug and having a large number of contact terminals.
