Embodiment Construction

[0014] The screw terminal A shown in the figure is ready to be installed on the electrical equipment. figure 1 Only the following elements of the device are shown in : an insulating housing 10 designed for a terminal block, and a fixed connection branch of a rigid conductor arrangement 11, on which one or several conductors can be screwed and fixed. With this method, figure 1 Two conductors c1 and c2 inserted above and below the branch respectively are shown. The housing 10 is located in the electrical equipment, that is, it is designed in a certain part of the equipment housing or in a lug fixed to the equipment housing.

[0015] The terminal block A consists of a connecting frame 12 of a common type formed by cutting and bending sheet metal to form a rectangular rigid ring. On the short side 12a, the rigid connecting frame 12 has a tapped hole 12b, and the connection branch of the conductor device 11 is inserted into the rectangular elongated hole 12c of the connecting fra...

Abstract

Screw terminal connected to a conductor device mounted on a piece of electrical equipment to connect at least one conductor, composed of a connection cage and a screw, the cage and / or the screw being movable inside the terminal housing. A pressure device (30) composed of a head plate (31) and a pressure plate (32) connected to each other by two elastic symmetrical wings (33, 34) designed to store torque energy, the head plate being convex in shape and attached by the screw neck. The pressure plate can be applied against a conductor or against the conductor device on the equipment, and the elastic wings are concave in shape, with a concavity that is reduced as the pressure on the screw is increased.

Description

technical field [0001] The invention relates to a screw terminal for connection to a conductor arrangement of an electrical device, for connecting at least one electrical conductor to the arrangement. technical background [0002] In particular, it relates to a screw terminal comprising a connecting frame provided with a tapped hole, a screw with a threaded head and a shank screwed into the tapped hole, and an elastic pressure device for acting on an electrical conductor. The connecting frame and / or the screw can move in the casing of the electrical equipment, and the pressure device includes a top plate and a pressure plate interconnected by elastic wings storing torque energy, the top plate bears pressure from the screw head, and the pressure plate acts on the conductor or Conductive elements of equipment. [0003] Document DE U 1935560 describes a terminal of this type. A U-shaped stirrup pressure device, consisting of upper and lower wings conne...
