Embodiment Construction

[0062] figure 1 A contact device 10 known from the prior art is shown, which is composed of a contact 11 , a connecting line 12 and a damping element 13 . The twisted end 14 of the connecting wire 12 is inserted into a recess in the contact 11 in the form of a hole 15 , the annular gap 16 between the twisted end 14 and the hole wall 17 being filled with filling powder 18 . During filling, the filling powder 18 is compacted so that the twisted ends 14 are firmly attached to the contacts 11 . In the region of the opening 19 of the bore 15 , a covering material 20 is applied to the side 21 of the contact 11 , which covers the filling powder 18 and the opening 19 . Since the covering material 20 is initially applied in liquid form, the covering material 20 forms a meniscal surface 22 between the side 21 and the twisted end 14 . After the covering material 20 is applied, the covering material will automatically set. The damping element 13 is fastened to the contact end 23 of the...

Abstract

The present invention relates to a method for producing a contact device and the contact device (63), particularly a electric brush device provided with at least one contact tip (64), at least one connection line (67) and at least one damper element (68). In order to constitute the damper element, a drill is machininged in surface of the contact tip, and the drill is partially filled with an elastically hardened casting compound.

Description

technical field [0001] The invention relates to a method for producing a contact device and a contact device, in particular a brush device, with at least one contact piece, at least one connecting line and at least one damping element. Background technique [0002] Contact devices or brush devices are already very familiar to us and are already used for contacting the commutator or slip rings of electric motors. The contacts are mainly made of graphite with various mixtures used as electrode materials, it being possible for the connecting conductors to be stranded wires, which are fastened in or on the contacts for the transmission of electrical energy. In addition, the contacts use the contact end to be close to the commutator or slip ring of the motor, and during the rotation of the commutator or slip ring, the contacts will be worn or worn out due to friction. At the same time, so-called brush sparks also have a decisive influence on the wear of the contacts. In additio...
