Abstract
Contact pins are mechanically fixed to hollow cylindrical insulation sleeves surrounding the contact pins at both ends of an infrared bright radiator by way of a circumferential recess within the inner wall of the hollow cylindrical sleeve or the opposed surface of the contact pin which receives a radial projection carried by the other of the two members to limit axial movement of the pin relative to the insulation sleeve.
Claims9
In an infrared bright radiator having insulating sleeve members surrounding contact pin members at respective pinched ends of the radiator and wherein each sleeve member comprises a hollow cylinder having at least an even outer circumferential surface and being provided with two diametrically opposed slits at the end facing away from the free end of the associated contact pin member, the improvement wherein each insulating sleeve member is formed of plastic material and wherein the surface of one of the contact of one of the contact pin or sleeve members facing the other is provided with a radial projection and the surface of the other contact pin or sleeve member facing that projection is provided with an annular recess receiving the projection an axially limiting movement of the contact pin and sleeve members with respect to each other.
