2 Claims. (Cl. 201-67) My invention relates to resistors and particuthe flange thereof toward the tube. For coniarly to resistors of the type in which a resistvenience in holding the eyelet in position on the ance conductor is supported on an insulating lead until the coating is applied and becomes member, the memberand conductor being sub hard one may pinch the sides thereof against 5 sequently coated with a protective insulating mathe lead. With the reinforcing member in place terial. on each of the connection leads the entire as- An insulating material commonly employed in sembly is given a coating of a suitable protective the past for coating resistors of this type is insulating material such, for example, as vitrevitreous enamel which is baked on after being ous enamel which is represented at 6 and which 10 applied to the resistor. Diiiiculty has been ex after being baked forms a hard heat resisting 10 perienced with resistors thus coated due to the covering. In consistency the material employed tendency of the enamel to break away at the for the coating should be somewhat thick so as points where the connection leads pass through to completely cover not only the tube and the it when the leads are flexed. Flexing of the resistance wire but also the eyelets which, as leads not only has caused the enamel to break shown in Fig. 2, thereby become firmly embedded 15 away around them but also has resulted in the in the material. breaking of the leads themselves or of some of While I have mentioned the use of vitreous the strands thereof, where stranded material is enamel as one example of a suitable material for used, due to a repeated sharp bending of the the protective coating it will be understood that lead over the edge of thebroken enamel.
