Title
(EN) HEAVY CURRENT REED SWITCH CONTACT STRUCTURE
(FR) STRUCTURE DE CONTACT DE COMMUTATEUR À LAME VIBRANTE À COURANT FORT
(ZH) 大电流簧片式开关触点结构
Abstract
(EN)
A heavy current reed switch contact structure comprises at least one set of elastic reed electrode (11, 12) or at least one fixed electrode (12) and an elastic reed electrode (11). The reed electrode (11, 12) is made of a conductive material. Contacts (13, 14) are arranged on opposing surfaces of mutually overlapping ends. A side of the end having the contacts is disposed with an arc discharge device (16, 162). The reed switch employs a specially designed contact structure, and the arc discharge structure device is additionally disposed on the basis of a traditional switch contact structure. As a result, the reed switch quickly transfers to the contact arc discharge structure device an instantons arc generated upon switching the switch contact, thereby easing burnout resulting from an arc on the contact surfaces of the contacts, enabling the contacts to be less prone to being adhered together, and considerably increasing a bearing current and a switching capacity of the reed switch. The heavy current reed switch contact structure has a simple structure and provides a heavy bearing current.

La présente invention porte sur une structure de contact de commutateur à lame vibrante à courant fort qui comprend au moins un ensemble d'électrode à lame vibrante élastique (11, 12) ou d'au moins une électrode fixe (12) et d'une électrode à lame vibrante élastique (11). L'électrode à lame vibrante (11, 12) est faite d'une matière conductrice. Des contacts (13, 14) sont agencés sur des surfaces opposées d'extrémités chevauchantes mutuellement. Un côté de l'extrémité ayant les contacts est disposé avec un dispositif à décharge en arc (16, 162). Le commutateur à lame vibrante utilise une structure de contact spécialement conçue, et le dispositif de structure de décharge en arc est de plus disposé sur la base d'une structure de contact de commutateur classique. En conséquence, le commutateur à lame vibrante transfère rapidement à la structure de décharge en arc de contact un arc instantané généré lors de la commutation du contact de commutateur, ce qui allège un effet d'usure résultant d'un arc sur les surfaces de contact des contacts, permettant aux contacts d'être moins susceptibles d'être collés conjointement, et augmentant considérablement un courant parasite et une capacité de commutation du commutateur à lame vibrante. La structure de contact de commutateur à lame vibrante à courant fort présente une structure simple et fournit un courant parasite lourd.

一种大电流簧片式开关触点结构,由至少一组具有弹性的簧片式电极(11、12)或至少一个固定电极(12)与一个具有弹性的簧片式电极(11)组成,簧片式电极(11、12)由导电材料制成,互迭端相对面有触点(13、14),有触点端部侧面有电弧放电装置(16、162)。该簧片式开关采用特殊设计的触点结构,在传统开关触点结构的基础上,增设电弧放电结构装置,将开关触点在通断的瞬间产生的电弧快速转移到触点电弧放电结构装置上,从而减轻电弧对电触点接触面的烧蚀,使触点不宜粘连,大幅度提高簧片式开关的电流承载和通断能力。该大电流簧片式开关触点结构结构简单、能提供更大承载电流。
