Application october 3o. 1940, serial No. 363,562
. 10 Claims.
This invention relates to connectors and loading coils for electric cable wires, and more particularly to devices for quickly electrically connecting adjacent ends of insulating conducting cables or quickly inserting loading between said adjacent ends, though it isnoted that in the `broader claims the invention is not limited to loading coils or to insulated conductors or cables, nor even to conductors.
One object of the invention is to provide an improved connector of this kind with which adjacent ends of insulated cable, such as field telephone lines used in the field by the arms may be very quickly, strongly and effectively electrically and mechanically connected.
Other objects of the invention are to provide an improved connector with which a loading coil is combined, and to provide a connector with which various types of flexible members may be quickly and strongly connected, and with which insulated conductors may be almost instantly connected without stripping the insulation while effecting a joint which is itself fully insulated.
Additional objects of the invention are to effect simplicity and emciency in such connectors and to provide an extremely simple device of this kind which is economical, durable, effective and reliable in operation, and economical to manufacture and apply.
Still other objects of the invention will appear as the description proceeds; and while herein details of the invention are described in the specification and some of the claims, the invention as described in the broader claims is not limited to these, and many and various changes may be made without departing from the scope of. theinvention as claimed in the broader claims.
'I'he inventive features for the accomplishment of these and other objects are shown herein in connection with two forms of connector each comprising a metal tube having an insulating covering, and one form comprising atube of alined sections insulated apart to which opposite ends of a surrounding loading coil are connected. In each of the forms the tube is provided interiorly with stop means at its mid part, and intermediately with a plurality of sharp-pointed triangular cut-out projections cut from the marial of the tube and integrally joining the metal of the tube at the base of the projection and pointing toward the axis of the tube and inclined away from the adjacent open ends of the tube, whereby when the cable ends are pushed into the tube to said stop means, and afterwards from the tube, the sharp points of the projections willdig through the insulation into firm electric contact with the wires of the cable thus yelectrically connecting the cable ends.
In the accompanying drawings showing, by
way of example, three of many possible embodiments of the invention:
Fig. 1 is a longitudinal sectional view, partly in elevation, showing one form of tube and its insulating covering;
Fig. 2 is a longitudinal sectional view, partly in elevation, showing the tube and cable ends as irst inserted;
Fig- 3 is a similar view showing the points engaging the conducting wires;
Fig. 4 shows a section taken on the line 4 -4 of Fs- 3:.
Fig. 5 is a longitudinal vertical sectional view, partly in elevation, showing the tube of a second form of the invention, the tube being a split tube:
Fig. 6 is an end elevation of the split tube;
Fig. 7 shows a section taken substantially on the line 'I-l of Fig. 5, looking in the direction oi the arrows of said line; y
Fig. 8 is a fragmental longitudinal sectional view, partly in elevation, showing a modified form of cutting the cable end; the section being taken substantially on the line 8-8 of Fig. 5, looking in the direction of the arrows of said line;
Fig. 9 shows astrip of metal with stop lugs and projections cut and stamped thereon, the strip being bendable to` the form of Figs. 5 and 6 in a curving die; and
Fig. 10 is an axial section partly in elevation.
showing the combined connector and loading coil.
Our improved connector is shown electrically connecting adjacent ends I0. Il (Fig. 2) of insulated wire conducting cable. The connector includes a tube I2 of conducting metal flared at both ends I3 and provided with a central impressed annular rib stop I4 around the interior of the tube, the inner diameter of said tube be-v ing about/the same as, or a little larger than, the diameter of the insulated cable, whereby the tube is adapted to receive said adjacent endswith a free or close push t until the adjacent ends of the cable are stopped by said rib stop M.
Said tube is provided with sharp-pointed acute 50 isosceles triangular cut-out projections or darts l5 cut from the material of the tube and integrally joining the mtal of the tube at the base or root- I6 of the projection, said projections being arranged spirally around along the tube on pulled upon'to draw them in an outward direction 55 both sides of said rib stop Il, and pointing toward the axis of the tube and inclined away from the adjacent open ends of the tube.
The nare il of the tubes facilitates the easy insertion of the cables, whereby the cable ends Il, Il may be pushed to said rib-stop Il while the insulation slides on and past the points of the projections Il. which may be somewhat flattenedbytheinsulationasshowninll'ig.2. After the cable ends have been thus inserted, the adjacent cable portions may be pulled upon to draw them in an outward direction from the stop Il (Pig. 3). whereupon the sharp points of the projections Ilwillcatch onanddigintoandthrough the insulation and be forced to a less inclined f position and dig into iirm electric contact with the wires of the cable i! as in Pig. 3, the projec-Y tions Il being so long, relative to the diameter of the tube and the diameter of the wire conducting part of the cable, that when the points have dug into firm contact with the cable wires, tbe projections will still be inclined away from the open ends of the tube, as shown in Fig. 3, thereby holding the end portions il, Ii of both pieces firmly within the tube and holding the wires il of both pieces in good firm electric contact with the points of the projections il and therefore in electric connection with the tube and each other.
As the tube I2 is thus in electric contact with thewlres Il.itisdesirablethatthetubebealso fully insulated. To this end the tubes I2 are at the factory or at least usually before they go to the ileld, covered with a somewhat yieldable or elastic tubular insulating covering I of loom, rubber or other suitable material (Fig. l) which may be pulled over the tube and retained in place by friction.
Fig. 8.
'I'he rib stop Il of Fig. l or the stop lugs il' of Fig. 5 may be used with either tube I2 or I2. The form of invention of Fig. l0 embodies a combined connector and loading coil, as for telephone or other lines. for electrically connecting ends of the insulated wire cables and also loading the line. Said combined connector comprises a pair of alined metal tubes i2a having slightly separated adjacent ends and ared outer ends I3, and provided along the interior of the tube with a plurality of large oval openings 2|, and remote from the openings with a plurality of sharppointed cut-out projections or darts II cut from the material of the tube and integrally joining the metal of the tubes as inFig. 1.
Tubular insulating sections il cover said tubes and extend beyond the outer ends thereof. An insulating disk ila forms stop means separating the ends of the tube and sections.
, A toroidal core 28, 2l, 21 of high magnetic permeability surrounding said tubes on said tubular covering I! is with outer and inner coaxial cylindrical walls 2l, 2O and end walls 21. enclosing an elongated annular coil receiving space 2l.
