Embodiment Construction

[0020] figure 1 It shows an electrical terminal 1 with an insulating material housing 2 in which metallic contact elements 4 are accommodated. The insulating material shell 2 has at least one wire lead-in hole 3 on its one end face, is used for inserting electric wire 5 ( figure 2 ). In the exemplary embodiment shown, the terminal clamp 1 is designed as a double pole, each pole having a conductor feedthrough 3 and a contact element 4 . However, the terminal clip can also have any other different number of poles.

[0021] Also from figure 1 It can be seen in the connection area 16 of the contact element 4, whose contacts make contact with the printed circuit board 7 ( figure 2 ) of the corresponding contact segment 28, such as a printed circuit. The connection area 16 is here in particular connected to the contact section 28 by a solder connection (SMD soldering), but a plug connection is also conceivable. exist figure 2 The contact element 4 fixed on the printed circ...

Abstract

The invention relates to a contact element (4) of an electrical terminal (1) for connecting at least one electrical conductor (5), wherein the contact element (4) is formed from a flat metal material and has a contact base (11) and At least one side wall (19) arranged along a bending line (17) from the contact base (4), and wherein the contact element (4) is a plate forming a wire connection terminal on the side wall with a tongue shaped from a flat metal piece Spring, which is bent out of the plane of the flat metal part, so that the free end of the leaf spring (9) constitutes the clamping edge (10) towards the electrical conductor (5) and is in contact with the base plate (11) and the leaf spring (9) ) to form a seam (13). According to the invention, embossings ( 22 ) which reduce the width of the slot ( 13 ) are provided in the region of the slot root ( 13 a ) forming the end of the slot ( 13 ).

Description

technical field [0001] The invention relates to a contact element of an electrical terminal block for connecting at least one electrical conductor, wherein the contact element is formed from a flat metal material and has a contact base and at least one side wall arranged along a bending line from the contact base, and the contact element To form a conductor terminal, the side wall has a tongue-shaped leaf spring formed from a flat metal part, which is bent out of the plane of the flat metal part in such a way that the free end of the leaf spring forms a clamping position towards the electrical conductor. edge and form a gap between the contact base plate and the leaf spring. Background technique [0002] In the case of contact elements according to the general concept with punched-out leaf springs, a slot with a certain minimum width is produced between the contact base plate and the leaf spring due to processing technology. The slot width can vary depending on the bending ...
