ものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to prevent the plug and plug receiver of a cable connector from being accidentally removed even if the cable is hit by a WI or the cable is pulled during use. This is related to the equipment that was used for this purpose.
ケーブルコネクタのプラグの抜け外れを防止するための
最も簡単な手段は、プラグとプラグ受けの対両面に設け
たフランジの側端同士をねじ止めすることである。The simplest means to prevent the cable connector plug from coming off is to screw the side ends of the flanges provided on opposite surfaces of the plug and the plug receiver.
しかし、このようにすると、プラグの着脱が面倒であり
、またねじを紛失するおそれがある。However, in this case, it is troublesome to attach and detach the plug, and there is a risk of losing the screw.
これを解消するため、たとえば第3図と第4図に示すよ
うな装置が知られている。To solve this problem, devices as shown in FIGS. 3 and 4, for example, are known.
