Problems solved by technology

[0003] However, it is a problem to apply different materials, since tearing is caused at the interface between the nozzle housing and the epoxy or between the epoxy and the resistance heating element, and this leads to the ingress of moisture and the resulting corrosion or short circuit

Embodiment Construction

[0024] The heating element in production, designated 1 as a whole, is shown in the drawing.

[0025] The heating element 1 comprises a PTC element 2 (also referred to as a ballast, a PTC resistor or a PTC thermistor) as the actual heat-generating element, which is supplied with electrical energy via a connection line 3 . The heating element 1 comprises an electrically insulating housing 7 in which the components are enclosed.

[0026] After heating element 1 (see Figure 4 ) are used in a heatable windscreen washer nozzle 10 for a motor vehicle. The windscreen washer nozzles 10 are provided with a base body 11 having nozzles 12 and water pipes 13 respectively leading to the respective nozzles, and a heating element 1 .

[0027] The heating element 1 has an electrical connection 14 for electrical contacting of the heating element, formed on the housing of the heating element 1 as an electrically insulated socket connection with respect to the base body 11 .

[0028] The base...

Abstract

Method for producing a heating element for a nozzle of a heatable windscreen washer device, in particular for a motor vehicle, with a base body having at least one nozzle and water pipes respectively leading to the nozzle, and with a heating element, the heating element Having an electrical connection for electrical contacting of the heating element, wherein the base body has a heating element gap in which the heating element is mounted, wherein the heating element has an electrically insulating housing, and the electrical connection is in the form of a socket connection that is electrically insulated relative to the base body Formed on the housing of the heating element, wherein, in order to form the housing of the heating element, the heating element with the connecting wires is extrusion-coated with thermoplastic injection molding and positioned there by at least one baffle, and correspondingly produced out of the windshield washer nozzle.

Description

technical field [0001] The invention relates to a method for producing a heating element for a nozzle of a heatable windscreen washer device, in particular for a motor vehicle, with a base body having at least one nozzle and water pipes respectively leading to the nozzle, and with a heating element, The heating element has an electrical contact for the electrical connection of the heating element, wherein the base body has a heating element gap in which the heating element is mounted, wherein the heating element has an electrically insulating housing, and is electrically connected to a socket electrically insulated relative to the base body The form of connection is formed on the housing of the heating element. Background technique [0002] In the case of heated windshield washer nozzles, it is known that electrical resistance heating elements are injected into corresponding gaps together with epoxy resin in the housing of the nozzle. Here the wires are either firmly thread...
