"Screwless double push terminals"

The innovation relates to a screwless double-pressure connector.

Screwless connection terminals are used in installation technology and in switch construction already known. However, they have the disadvantage that they are equipped with a two-legged steel spring bracket and with an inserted connecting conductor the contact pressure against the abutment is only exerted by one leg at one point.

The aim of the innovation is to create a screwless connector which, after inserting the connecting conductor, the contact pressure against the abutment is transmitted from two legs to two points and thus a more intense one Contact is guaranteed.

This is achieved according to the innovation in that chambers are formed in the base are, which have recesses to the outside for the implementation of the connection conductor and retaining cams in the bottom for receiving and holding a steel spring. The U-shaped steel spring also has triangular recesses provided, which serve to better guide and hold the connection conductor. When the spring pressure takes effect after the connecting conductor has been inserted the same is pressed with both leg ends against the abutment, whereby contact is made in two places.

In order to pull out the connecting conductor or insert multi-wire To enable ladders, the clamp is equipped with a pressure plate, which is preferably made of thermoplastic and with its foot part in one The recess of the abutment is held in a spring-locking manner. When the pressure plate is pressed down, the legs of the U-shaped steel spring move downwards moved and thus released the connecting conductor or the introduction of a multi-wire Head allows.

The innovation is explained below in conjunction with a drawing. It show:

Fig. 1: A schematic representation of the clamp in side view.

Fig. 2: A schematic representation of the terminal with inserted connecting conductor,

Fig. 3: A section through the clamp in the direction of the view from the front.

In a base part (i) chambers (2) are arranged which have recesses towards the outside (3) for the implementation of the connecting conductor (4). The retaining cams (5) arranged in the bottom of the chamber serve to hold and hold the U-shaped steel spring (6). When inserting a solid connection conductor (4) the legs of the U-shaped steel spring (6) are used for the better Guiding and holding of the conductor provided with triangular recesses (7) is pushed away in the axial direction. At the same time the head is through the force of the bias against the abutment (8) and printed for the purpose of a More intensive contact is held by both legs of the U-shaped steel spring (6). When loosening this contact connection or when inserting a stranded wire Head we the pressure plate (9) with its foot part (1O) in the Abutment (8) is held in a spring-locked manner, moved downwards. By pressing on the two legs of the U-shaped steel spring (6), the Aiischlußleiter (4) is released and pulling out the solid conductor or inserting a stranded conductor Head allows.

Claims (4)

Protection claims: 1.) Screwless double-push terminals for switches, plug-in devices or the like, characterized in that chambers (2) in the base part (1) are attached. In the chambers (2) U-shaped steel springs () are housed, which have the task of the inserted connecting conductor [) by the force of the preload in two places against the abutment '8) to create an intensive and secure contact connection. 2.) Screwless double pressure connection terminal according to claim 1, characterized in that that in the bottom of the chamber (2) a crouch (5) is attached, which serves to receive and hold the U-shaped steel spring (6). 3.) Screwless double-pressure connection terminal according to claims 1 and 2, characterized in that that the U-shaped steel spring has triangular recesses (7) that better guide and hold the connection conductor guarantee. 4.) screwless double pressure connector according to claim 1, 2 and 3 thereby characterized in that the pressure plate (9) with its foot part (1O) in the abutment (8) is held in a spring-locked manner.
