Embodiment Construction

[0023] Fig. 1 shows the cross-sectional view of terminal box 10, and terminal box 10 has a box cover 11 that is arranged along the wire insertion direction, and this box cover 11 has wire insertion openings 12, 13 and 14, so that the total number of inserting in the same orientation and parallel is Three wires 15 (see Figure 3).

[0024] Figures 4, 5 and 6 show the contacts incorporated into the terminal box. The contact is composed of a spring steel plate 16 (see FIG. 6 ) and a bus bar 17 (see FIG. 5 ), and the bus bar 17 is made of copper with good electrical conductivity.

[0025] Corresponding to the number of clamping points, three leaf spring tongues 21 are punched out of the spring steel plate 16 , whereby window recesses are produced in the spring steel plate. The size of the window recess corresponds substantially to the size of the punched-out leaf spring plus the end section 25 , best seen in FIG. 6 . The wires 15 are inserted through the window openings, and the ...

Abstract

The present invention relates to a connecting terminal for electric wires. The terminal operates with a leaf spring tongue die-cut (or blanked) from a piece of spring steel plate and has a busbar extending over all clamping locations. The object of the invention is to reduce the structural height of the terminal. This task was solved by a new positioning of the edge areas of the spring steel plates so that they were each closely adjacent to the wires. The reduction in structural height is also achieved by a new contact configuration with special pre-deformation of the leaf spring tongues.

Description

technical field [0001] The invention relates to an electrical terminal for the connection of electric wires to terminal boxes made of insulating material and for the connection of electric wires to a contact (Kontakteinsatz) having a plurality of adjacently arranged in a row Clamping locations, the stripped ends of the wires are inserted parallel to each other from the same side of the terminal box into adjacently arranged clamping locations. Background technique [0002] The contacts of such terminals usually consist of a spring steel plate and a bus bar made of a material with good electrical conductivity and common to all clamping points. Corresponding to the number of clamping points, a plurality of leaf springs in the form of leaf spring tongues are punched out of the spring sheet metal block, whereby their tongue bases are connected to the upper edge region of the spring sheet metal. The free ends of the leaf spring tongues extend in the direction of the lower edge of...
