Abstract
For transmitting high currents, such as in the electrical system of a motor vehicle for example, a contact element is proposed which is rolled and stamped from sheet-metal material and which consists of a contact-making section, a conductor-connecting section and a fastening section with an overlapping sleeve. In the contact element, the sleeve is at a radial distance from the fastening section.

A contact element made of stamped and rolled sheet-metal material and having a contact-making section, a conductor-connecting section, and a fastening section for fastening the contact element in a receiving chamber in an insulating body, characterized in that there is pushed on, over the fastening section (5) of the contact element, a sleeve (3) which is disposed at a radial distance from said fastening section, said radial distance being set at a predetermined minimum separation distance between the sleeve (3) and the fastening section (5) to provide a permanent circulation of air and constant dissipation of heat between the sleeve (3) and the fastening section (5), characterized in that the sleeve (3) is provided with inwardly bent distance flaps (18) which are distributed over the periphery and by means of which the sleeve is centered on the fastening section (5).
A contact element made of stamped and rolled sheet-metal material and having a contact-making section, a conductor-connecting section, and a fastening section for fastening the contact element in a receiving chamber in an insulating body, characterized in that there is pushed on, over the fastening section (5) of the contact element, a sleeve (3) which is disposed at a radial distance from said fastening section, said radial distance being set at a predetermined minimum separation distance between the sleeve (3) and the fastening section (5) to provide a permanent circulation of air and constant dissipation of heat between the sleeve (3) and the fastening section (5), characterized in that inwardly directed arresting flaps (21, 22), by means of which the sleeve (3) is held on the fastening section (5) in such a way as to be secured against axial displacements, are constructed on the ends of said sleeve (3).
A contact element made of stamped and rolled sheet-metal material and having a contact-making section, a conductor-connecting section, and a fastening section for fastening the contact element in a receiving chamber in an insulating body, characterized in that there is pushed on, over the fastening section (5) of the contact element, a sleeve (3) which is disposed at a radial distance from said fastening section, said radial distance being set at a predetermined minimum separation distance between the sleeve (3) and the fastening section (5) to provide a permanent circulation of air and constant dissipation of heat between the sleeve (3) and the fastening section (5), characterized in that the sleeve (3) is provided with outwardly bent spring flaps (15), that inwardly directed folded portions (16) are formed on the spring flaps (15), and that hook-shaped ends (17) on the folded portions penetrate into clearances (7) in the fastening section (5) and secure the sleeve (3) against radial twisting.
A contact element made of stamped and rolled sheet-metal material and having a contact-making section, a conductor-connecting section, and a fastening section for fastening the contact element in a receiving chamber in an insulating body, characterized in that there is pushed on, over the fastening section (5) of the contact element, a sleeve (3) which is disposed at a radial distance from said fastening section, said radial distance being set at a predetermined minimum separation distance between the sleeve (3) and the fastening section (5) to provide a permanent circulation of air and constant dissipation of heat between the sleeve (3) and the fastening section (5), characterized in that the contact element is constructed as a pin contact (1), the contact-making section (4) of which is formed by contact tongues (9) which are bent in a barrel-shaped manner and are separated by slits (10), that said slits (10) extend right into the fastening section (5), and that the contact tongues (9) are provided, immediately after the fastening section (5), with a constricted portion (8), the diameter of the contact-making section (4) being reduced compared with said fastening section (5), characterized in that outwardly pointing embossed portions (32) are raised up on the contact tongues (9), that the front ends (30) of said contact tongues (9) are bent radially towards the central axis of the pin contact (1) and, under these circumstances, point towards one another in the shape of a star, and that, in the condition in which they are not plugged into a socket contact, the front ends (30) of the contact tongues (9) are at a lateral distance (31) from one another.
