Repetitive rotation, i.e., when the connecting member 240 is repeatedly bent, causes a fatigue load to act on the connecting member 240.

Abstract

L'invention concerne une pince qui est montée sur une carte de circuit imprimé afin de permettre une connexion directe et électrique à un câble externe, par exemple un câble plat flexible, et la carte de circuit imprimé. La pince selon la présente invention comprend : une base ayant un organe avant, un organe arrière et un organe latéral connectés à une forme d'armature, et l'organe latéral ayant un organe de verrouillage; et un couvercle ayant un organe latéral, un organe de plaque connecté à l'organe latéral et correspondant à l'espace de la base, au moins une pièce de pression agencée au centre de l'organe de plaque et dont une extrémité s'étend depuis l'organe de plaque de sorte que l'organe de pression puisse tourner autour de la partie adjacente à l'organe de plaque, et une pièce de verrouillage formée au niveau de l'organe latéral. Quand un câble est placé dans l'espace de la base qui est fixé sur la carte de circuit imprimé, le couvercle tourne vers la base pour permettre ainsi à la pièce de pression du couvercle de presser le câble externe vers la carte de circuit imprimé et au couvercle d'être verrouillé à la base par l'organe de verrouillage et la pièce de verrouillage.
