Embodiment Construction

[0032] figure 1 and 2 The basic components of the heating element according to the invention are shown, which have a PTC element 2 which is electrically conductively connected with its main side 4 to a contact lug 6 . For this purpose, the contact lug 6 has a plurality of spring tongues 8 formed integrally on the contact lug 6 by punching and bending. These spring tongues 8 in figure 2 and image 3 can be regarded as sections of the contact strip 6 protruding from the contact surface 10 formed by the contact strip 6 by punching and bending, and these sections are not so much in the form of a whole area, but rather in the form of points or lines Attached to the PTC element 2.

[0033] exist Figure 1 to Figure 3 In FIG. 2 , the retaining lug 12 can also be seen, which is integrally formed on the contact piece 6 by punching and bending and protrudes beyond the contact surface 10 of the contact piece 6 , which is configured to the size of the main side 4 . Retaining tab 12...

Abstract

The invention relates to a heat-generating element comprising a PTC element (2) and a contact piece (6) which is electrically conductively attached to a lateral surface (4) of the PTC element (2) andwhich is provided for feeding the PTC element (2) with different polarities. The aim of the invention is to permanently and reliably establish a contact between a contact piece and a PTC element and to easily operate a heat-generating element within the scope of a production scheme. According to the invention, at least one contact piece (6) is provided with a retaining tab (12), which rests against the opposite side (4) of the PTC element (2), on which the other contact piece (6) rests in an electrically conductive manner, with an insulating layer interposed therebetween, and which engages over the PTC element (2) in a form-fitting manner.

Description

technical field [0001] The invention relates to a heating element with a PTC element (Positive Temperature Coefficient Element) and a contact strip conductively pasted on the PTC element for feeding the PTC element. Background technique [0002] Such heating elements are used in various technical fields. In particular, the invention relates to a heating element for a motor vehicle. Heating elements of the type mentioned here are used as heaters to compensate for the insufficient heating of the air introduced into the passenger compartment through a heat exchanger connected here to the cooling water of the engine, or also in electric vehicles, with In heaters that heat the interior of the car and defrost the windshield. This also applies to the heating element according to the invention. [0003] In motor vehicles, heating elements are exposed to special conditions. Therefore, a considerable temperature range must be considered in the design. Vehicles can be used in very...
