Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that conventional connectors can not be used at a place with water leakage since they are of a drip-proof structure, not of a water-proof structure. <P>SOLUTION: A BNC connector is covered with a first cover and a second cover, with O-rings set at a connecting part of the first and the second covers to avoid water leakage. If the BNC connector is of a type fixed to a panel, the second cover is fixed when the BNC connector is fixed to the panel to have the O-rings prevent water leakage. When the BNC connector is used for connecting a cable to another, the second cover is to be structured in the same way as the first cover. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、着脱が容易で、直流から高周波に到るまでの広範囲な周波数特性と低漏洩特性を保有していることから通信情報機器に到るまで用いられる防水コネクタに関するものである。   The present invention relates to a waterproof connector that is easy to attach and detach and has a wide range of frequency characteristics and low leakage characteristics from direct current to high frequency, so that it can be used for communication information equipment.

従来のコネクタとしては、ロックナット部に水密用のＯリングを取り付けた防滴構造である。   A conventional connector has a drip-proof structure in which a watertight O-ring is attached to a lock nut portion.

しかしながら、このような従来のコネクタは、防滴構造であって、防水構造ではないため、水漏れするような部分には使用できず、又、一般的な構造になっていないために、特別品として購入しなければならないという問題があった。
特開平４−２９４０７４号 However, such a conventional connector has a drip-proof structure and is not a waterproof structure, so it cannot be used in a portion that leaks water, and is not a general structure. There was a problem that had to be purchased as.
JP-A-4-297474

解決しようとする問題点は、従来のコネクタは、防滴構造であって、防水構造でないため、水漏れのある部分では使用できない点であり、又、特別品であるため、その都度購入しなければならないという点である。   The problem to be solved is that the conventional connector is drip-proof and not waterproof, so it cannot be used in areas where water leaks, and it is a special product, so it must be purchased each time.
