Problems solved by technology

In addition, the size of the flexible conductors and connection terminals may also be large, so the welding system must have an adequate power level
[0007] For example, ultrasonic welding does not have the annealing drawbacks mentioned above, but cannot be used due to its known power limitations

Embodiment Construction

[0031] see figure 1 , The element constituting the connection means is the connection terminal 1 , which forms a substantially parallelepiped with an upper surface 11 and a lower surface 12 , two side surfaces 13 and 14 , and an end surface 15 . The connection terminal has one or more substantially parallelepiped-shaped grooves 150 on the end surface 15, which pass through the entire thickness of the connection terminal. Indeed in this example it can also be said that the profile of the end surface 15 is square-wave-shaped.

[0032] The second element constituting the connection means is a flexible conductor 2 having an end 21 whose shape substantially matches the inner wall of the groove 150 .

[0033] see figure 2 , shows that the connecting device according to the invention is constituted by the end 21 of the wire 2 which is inserted into said groove 150 . In this example the flexible conductor 2 protrudes from the lower surface 12 of the connection terminal 1 substanti...

Abstract

A Junction between a flexible conductor and a connection terminal, whose particularity consists of the fact that it comprises: a connection terminal that is shaped substantially like a parallelepiped and has an upper face and a lower face, two side faces and an end face, and has, on the end face, one or more slots shaped substantially like a parallelepiped, which run through the entire thickness of the connection terminal; at least one flexible conductor, in which one end part is shaped so as to mate substantially with the inner walls of the slots; the end part being inserted in the slots, and the flexible conductor protruding substantially at right angles from one of the upper, lower or end faces; at least one laser welding bead, which runs at said slots along at least one of the two faces from which the flexible conductor does not protrude.

Description

technical field [0001] The invention relates to an element for connecting flexible conductors, in particular for connecting flexible conductors of low-voltage circuit breakers and contactors. The invention also relates to a method for connecting a flexible conductor, in particular one or more braids, to a connection terminal, in particular a connection terminal of a moving contact of a low-voltage circuit breaker or contactor, by means of laser welding. Background technique [0002] Circuit breakers and contactors usually have flexible conductors that connect the moving and stationary contacts. The methods used in the prior art to connect such flexible conductors to the moving contacts and to the static contacts are generally based on a brazing process. [0003] These processes generate high temperatures for extended periods of time in a large area around the weld zone. This causes the wires, usually made of copper, to anneal, degrades or deteriorates the mechanical proper...
