(C1. 173-251) An object of this invention is to provide an im- ' the screw’. engaging a threaded hole in the end proved formof connecter to electrically connect two wires or cables together. A further object is to provide a connector be 5 tween two wires or cables one of which is enclosed within an outer metallic shielding cover, the con necter being also designed to support the latter wire entirely by means of its metallic cover. Other and further objects of the invention will 10 become apparent to those skilled in the art as the description thereof proceeds._ For a better under standing of the invention, however, reference is made to the accompanying drawing in which; Fig. l is a partial cross section of a connecter 15 made according to my invention, and Fig. 2 is a side view of the connecter shown in Fig. 1. Terminals or connecters of the kind )heretofore of cap I. This conical clamp device after mounting con stitutes a self-enclosed unit with which a suspen sion device and contact terminals for the drain 5 wires may be united. In the exempli?ed embodi ment shown, the screw cap 0 has at the top the form of a bolt support or screw upon which a terminal cap may be screwed as indicated at I. This cap I is suspended from a wire clip I. (Fig. 10 2) which is held by an egg-shaped insulator chain It. The screw cap I also serves to estab lish fixed connection between lead-oi! wire ll and the clamp device or terminal. The action of the arrangement is as follows: u The clamp cone member 4 inserted underneath the braided cover I presses the latter. after the that the tension produced by the weight of the clamp nut I has been shifted over and after it has been screwed fast with the cap t, with great force against the conical inside surface of the . line or feeder is jointly taken up by the sheath and the inside conductor. As a result of the per clamp nut. In this manner the extraction of the braided cover i which alone supports the mostly used are without exception of such a kind manently acting tractive and occasionally also ?exural stresses, the slender inside conductor is a ‘subject to a risk of breaking. In addition the mounting .of such terminals is attended with serious dimculties, especially in shielded radio frequency or antenna feed leads, which, as is well known, because of the capacitive action of a the screening metal sheath are of large diameter and. of especially suitable hollow forms of con entire weight of the cable and occasionally also ilexural strains thereof is prevented. The inside conductor I is brought out of the screw 'cap I through the inside bore so that there is suillcient play or clearance. and connected with the ter minal screw 8 so that thus perfect relieving of stress of the slender inside conductor without compressive or bending eil'ects is insured. “ Having described my invention, what I claim struction for the insulating and the supporting as novel and desire to secure by Letters Patent is! or strain material. 1. Means for supporting a vertically depending cable having an outer metallic braiding and a central insulated conductor without strain on the a central conductor, comprising in combination a hollow nut tapered internally and in contact with the outer surface of said braiding, a wedge be tween the insulation and the interior surface of said braiding, a hollow member having an inter- ‘0' nally threaded portion engaging said nut and a reduced shoulder portion adapted to engage the end of said wedge to thereby expand the end of In the terminal here disclosed these disadvan 35 tages are obviated. According to this invention the terminal of a line or feeder has a conical clamp which alone, so rubber device- for receiving the braiding cover thus is called upon to support the line whereas the inside conductor and the envelope thereof are not called upon to withstand any tension. - As shown in the sectional view Fig. 1, i denotes the braided metallic envelope of a line or feeder comprising the inner conductor I and its insu 45 lation covering 2. Between the insulation cover ing and the braiding on top is introduced a pref erably separate clamping cone member 4 of in sulating material. Fitted thereover is a clamp nut 5 also of insulation material and having a 50 correspondingly shaped inside bore, said nut piece 5 being screwed in a screw cap t. The inside con said braiding and maintain it ?rmly in contact with the tapered surface of said nut, screw means ‘5 for securing the upper end of the central con ductor to the upper surface of said hollow mem ber in the absence of tension in said conductor, a vertically depending supporting member engag ing the upper portion of said hollow member and ‘0 serving as a supporting means for said cable and ductor 3 passes through co-axial bores in the a lead wire clamping means intermediate the clamp cone member and in the screw cap as well last two members for providing a conductive con as the longitudinal slot indicated at ‘I and loosely 55 in the extension of the screw cap is locked under nection between said conductor and an external circuit. ll ' 2 2,118,108 2. A connecter device comprising the combina tion of a cable having an outer metallic sheath extending along substantially its entire length and serving as a shielding means, an inner con ductor insulated therefrom, a clamp nut tapered to engage said sheath and having a central aper ture passing said inner conductor, a tapered wedging member inserted between the insulation and the outer metallic sheath of said cable, a 10 member provided with screw means wedging said tapered member longitudinally of said cable, said last named member being hollow and passing said inner conductor, securing means arranged to secure said conductor to the end of said last named member, a supporting member engaging the upper portion of the last named member and serving as a supporting means for the cable and a lead wire clamping means positioned between the supporting member and the last named mem ber for providing a conductive connection be tween the conductor and an external circuit.
