Solderable electrical connection elements

Abstract

The invention relates to a solderable electrical connection element comprising a crimped region for accommodating a connecting cable and a soldering region for a materially bonded connection to a surface of an electrically conductive structure, wherein the soldering region Directly connected to the crimped area or spaced apart from the crimped area by a transition area and a solder reservoir is arranged or can be mounted on the soldering area. According to the invention, in the section between the crimping region and the soldering region or in the transition region, the bend is formed such that the crimping region and the soldering region come into a back-to-back position, wherein the free side of the soldering region accommodates the solder storage department.

Description

technical field [0001] The invention relates to a solderable electrical connection element comprising a crimped area for receiving a connecting cable and a welding area for materially bonded connection to a surface of an electrically conductive structure, said welding area directly Connected to or spaced from the crimped region by a transition region, and a solder reservoir is provided or mountable on the soldering region. Background technique [0002] An electrical connection element is previously known from DE 20 2013 006 781 U1. The electrical connecting element is used for contacting, for example, the motor vehicle window with an electrically conductive structure arranged there, for example a heating conductor or an antenna conductor. Such electrically conductive structures are often connected to the on-board electronics via soldered electrical connection elements. [0003] The previously known connecting element has a region crimped around the connecting cable and a s...

Problems solved by technology

[0013] However, the connection elements described above have the disadvantage that due to the fact that the crimped region and the welded region lie essentially in one plane, they require a larger surface area that has to be taken into account in terms of assembly.

[0014] In addition, despite the possible transitions between the soldering area and the crimping area, there is still the risk that during the soldering process, solder enters the crimping area and reinforces the ends of the connecting cables in the form of twisted wires there, furthermore Rather, the liquid solder penetrates into the space between the individual cores of the respective litz wire determined by capillary force

This results in an undesired reinforcement of the cable, with consequent risk of breakage

[0015] Another disadvantage is that there is a risk of contamination of the section of the crimping area by the flux required for carrying out the welding process
