Fixing Device for the second earth

본 고안은 전자제품의 접지장치에 있어 접지용 단자의 고정장치에 관한 것으로, 접지전선이 접지대상물에 용이하게 설치되게 하고 접지전선이 접지대상물에 설치 완료된 후에도 접지전선이 쉽게 헐거워져 접지기능이 저하되는 것을 방지하여 제품의 신뢰도를 높이기 위한 것이다. The present invention relates to a fixing device for the grounding terminal in the grounding device of the electronic product, and the grounding wire is easily installed on the grounding object, and the grounding wire is easily loosened even after the grounding wire is completely installed on the grounding object. It is to increase the reliability of the product by preventing it. 이를 위해 접지대상물에 접지되는 부분을 스프링과 같은 탄성체를 이용하여 감싸는 구성부분을 가지며 접지전선과 접지 스프링부분을 연결할 수 있는 결속부분으로 구성된다. 접지대상물이 각종 배관일 경우 접지하기가 용이하지 않고 쉽게 분리되는 단점이 있으므로 스프링과 같은 탄성전도체를 이용하면 설치 및 유지가 용이하며 탄성체의 자체 탄성으로 지속적인 양호한 부착상태가 가능하므로 필요한 접지저항을 일정수준으로 유지할 수 있다. To this end, it has a component that surrounds the grounded part to be grounded using an elastic body such as a spring, and is composed of a binding part that can connect the grounding wire and the grounding spring part. If the grounding object is various pipes, it is not easy to ground and can be easily separated. Therefore, using an elastic conductor such as a spring makes it easy to install and maintain. You can keep it at the level.

L'invention concerne un dispositif de mise à la masse comportant un goujon métallique (20) doté d'une première tige filetée (21) et d'un collet (22) s'étendant radialement à la base de cette tige (21), le goujon (20) étant destiné à être fixé contre une paroi métallique (4) de sorte que le collet (22) soit plaqué contre une première face (4B) de la paroi (4), la première tige (21) étant destinée à coopérer avec un premier écrou (5) pour permettre la fixation d'au moins une cosse (40) enfilée sur cette première tige (21), le goujon comportant une seconde tige filetée (23) alignée coaxialement avec la première tige (21) et s'étendant à l'opposée de cette dernière depuis le collet (22), cette seconde tige (23) étant engagée au travers d'un orifice (6) ménagé dans la paroi (4), puis vissée dans un second écrou (7) soudé sur le pourtour de l'orifice (6) contre la seconde face (4A) de la paroi (4), le collet (22) présentant une section externe polygonale destinée à assurer le vissage de la seconde tige (23) sur le second écrou (7). The invention relates to a grounding device comprising a metal stud (20) having a first threaded rod (21) and a collar (22) extending radially at the base of this rod (21), the stud (20) being intended to be fixed against a metal wall (4) so that the collar (22) is pressed against a first face (4B) of the wall (4), the first rod (21) being intended for cooperate with a first nut (5) to allow the attachment of at least one lug (40) threaded on this first rod (21), the stud having a second threaded rod (23) aligned coaxially with the first rod (21) and extending to the opposite of the latter from the collar (22), this second rod (23) being engaged through an orifice (6) formed in the wall (4), then screwed into a second nut (7). ) welded on the periphery of the orifice (6) against the second face (4A) of the wall (4), the collar (22) having a polygonal outer section intended to ensure the screwing of the second ...

Heavy current connector for repair work on railway rails - has two sprung conical contacts gripping rails base flange above and below

The high-current connector is used to earth or to provide a temporary bridge along railway rails whilst repair work is being performed on the stretch between. It consists of a clamp with conical contacts that contact the base flange of the rail on each side i.e one above and one below. The conical contacts are spring loaded by elastic washers and each seated in a socket at the end of an arm. The two arms form an acute angle with one another. The current lead is bolted to the junction between the arms. A lever is used to tighten the top contact down onto the rail flange.
