Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral 20 indicates generally an electric cable connector constructed in accordance with the invention.
The electric cable connector 20 is adapted for use with heavy duty electric cables 21 of the type used for electric welding and the like. The electric cable 21 includes a relatively large conductor wire 22 covered by an insulating cover 23. The wire 22 extends beyond the insulating cover 23 at one end and has a lug 24 of conventional design clamped onto the wire 22. The lug 24 includes a generally flat tongue 25 having a transverse bore 26 extending therethrough.
The construction of the cable 21 and lug 24 is conventional.
A generally cylindrical body 27 is formed of conducting metal and has a pair of transversely extending slots 28 opening through the opposite ends thereof. The open ends of the slots 28 are flared at 29 to assist in inserting the tongue 25 of the lug 24 into the slot 28. A transverse threaded bore 30 is formed in the body 27 adjacent each end thereof communicating centrally with each of the slots 28. A set screw 31 is threaded into each of the threaded bores 30 and has a domed inner end 32 for engaging in the transverse bores 26 of the lug 24 to clamp them in the slots 28. The set screw 31 has an Allen socket 33 extending axially into the end thereof opposite the dome 32 to permit an Allen wrench to be engaged therewith for tightening the set screw 31 onto the tongue 25 of the lug 24.
A generally cylindrical insulating sleeve 34 has a length sufficient to cover the body 27, both lugs 24 and extend over a portion of the insulating cover 23 of each of the cables 21. The inner diameter of the sleeve 34 engages the outer diameter of the cylindrical body 27 and a set screw 35 extends through a bore 36 in the sleeve 34 and into the body 27. The head 37 of the set screw 36 extends above the body 27 into the bore 36 to lock the sleeve 34 onto the body 27. Bores 37 formed in the sleeve 34 align with the sockets 33 of the set screws 31 to permit the set screws 31 to be loosened or tightened without removing the sleeve 34 from the body 27.
While the body 27 has been shown as cylindrical and the sleeve 34 also shown as cylindrical it should be understood that any other desired cross-sectional shape may be used such as hexagonal, square and the like when desired.
In the use and operation of the invention illustrated in FIGS. 1 through 3 the sleeve 34 is assembled onto the body 27 and the set screw 35 is inserted through the bore 36 to lock the sleeve 34 to the body 27. The set screws 31 are backed off in the threaded bores 30 to open the slots 28 to permit tongues 25 of the lugs 24 to be inserted therein. The set screws 31 are then moved downwardly in the threaded bores 30 by means of an Allen wrench (not shown) until they have clamped tightly against the tongues 25 engaging in the transverse bores 26 thereof. When it is desired to disconnect the cables 21 it is only necessary to loosen one of the set screws 31 so that the cooperating lug 24 may be withdrawn therefrom.
Referring now to FIGS. 4 through 8 a modified electric cable connector is illustrated generally at 40. The electric cable connector 40 is adapted for use with electric cables 21 as described in FIGS. 1 through 3.
The electric cable connector 40 includes a longitudinal body half 41 and a longitudinal body half 42 which together are of generally cylindrical form and have conically tapering end portions 43, 44. The body half 41 has a bore 45 adjacent the conical end portion 42 opening through the center face thereof. The bore 45 has a cylindrical boss 46 formed at its inner end on which to mount one end of a compression coil spring 47. A bore 48 is formed in the body half 42 in axially aligned relation to the bore 45 and has a boss 49 formed in its inner end to receive the opposite end of the compression coil spring 47. The coil spring 47 normally urges the body halves 41, 42 apart.
A bore 50 is formed in the body half 41 adjacent the conical end 44 thereof and opening through the inner face of the body half 41. A cylindrical boss 51 is formed in the inner end of the bore 50 and a compression coil spring 52 is mounted thereon. A bore 53 is formed in the body half 42 in axially aligned relation to the bore 50 and has a boss 54 formed in its inner end and the compression coil spring 52 has its opposite end mounted thereon. The compression spring 52 normally urges the body halves 41, 42 apart.
The body half 41 adjacent the tapered end 43 is provided with a dome 55 extending toward the body half 42 and the body half 42 is provided with a semi-spherical socket 56 aligned with the dome 55 to receive the dome 55 when the body half 41 is brought into engagement with the body half 42.
The conical end 44 of the body halves 41, 42 have their inner opposed faces serrated at 57, 58 respectively for reasons to be assigned. An insulating generally cylindrical clamping sleeve 59 is externally threaded at 60 on one end thereof and has a reduced diameter portion 61 formed internally thereof with a conical opening 62 extending therethrough for engagement with the conical taper 43 on the body halves 41, 42.
A clamping sleeve 63 is externally threaded at 64 at one end thereof and has a reduced diameter portion 65 formed internally thereof with a conical opening 66 extending therethrough for cooperation with the conical taper 44 of the body halves 41, 42. The threads 60 and the threads 64 are formed oppositely for reasons to be assigned.
A generally cylindrical insulating sleeve 67 is internally threaded at 68 with threads to cooperate with the threads 60 and is internally threaded at its opposite end at 69 to cooperate with the threads 64. Rotation of the sleeve 67 about its axis will draw the clamping sleeve 59 and the clamping sleeve 63 inwardly when rotated in one direction and force them outwardly when rotated in the opposite direction. Inward movement of the clamping sleeve 59, 63 toward each other causes the conical openings 62, 66 to force the tapered ends 43, 44 toward each other to bring the body halves 41, 42 into contact. As the clamping sleeve 59, 63 are moved away from each other in an outward direction the springs 47, 52 force the body halves 41, 42 apart release anything clamped therebetween. The dome 55 on the body half 41 engages through the bore 26 of one of the lugs 24 and as the body halves 41, 42 are drawn together the tongue 25 is clamped tightly therebetween. At the opposite end of the connector 40 the wire 22 is engaged between the serrated faces 57, 58 respectively of the body halves 41, 42 and is clamped therebetween by axial movement of the clamping sleeve 63 with respect to the body halves 41, 42.
Referring now to FIGS. 9 through 11 another modified cable connector is illustrated generally at 70. The cable connector 70 is adapted for use with electric cables 21 as described in the preferred form of the invention, illustrated in FIGS. 1 through 3.
The cable connector 70 includes a longitudinal extending body half 71 and a longitudinally extending body half 72 which together are generally cylindrical in outer form.
The body half 71 has its opposite end portions inwardly tapered at 73 and the body half 72 has its opposite end portions inwardly tapered at 74.
The body half 71 has a central threaded bore 75 extending therethrough and has a pair of domes 76 formed thereon adjacent the opposite ends thereof. The body half 72 has a central bore 77 extending therethrough in axially aligned relation with the threaded bores 75 and has a counter bore 78 communicating with the outer end thereof. The body half 72 has a pair of sockets 79 of semi-spherical shape arranged in aligned relation with the domes 76 to encompass the dome 76 when the body halves 71, 72 are in engagement with each other.
A clamping bolt 80 extends through the bore 77 of the body half 72 and into the threaded bore 75 of the body half 71 with its head 81 engaged in the counter bore 78 so that the body halves 71, 72 may be clamped together thereby. The head 81 has an Allen socket 82 formed therein to receive an Allen wrench (not shown) for tightening and loosening and the clamping bolt 80.
A generally cylindrical insulating sleeve 83 is engaged over the body halves 71, 72 and has a length sufficient to extend over the insulation 23 of the electric cables 21 at each end thereof. The sleeve 83 has a central transverse bore 84 extending therethrough in axially aligned relation to the clamping bolt 80 to permit the clamping bolt 80 to be adjusted with the sleeve 83 in position overlying the body halves 71, 72.
In the use and operation of the invention lugs 24 are engaged with their tongues 25 between the body halves 71, 72 and with the domes 76 projecting upwardly into the bores 26 in the tongues 25. The clamping bolt 80 is tightened to establish a clamping relation between the body halves 71, 72 and the lugs 24.
The body halves 71, 72 in the form of the invention illustrated in FIGS. 9 through 11 and the body halves 41, 42 in the form of the invention illustrated in FIGS. 4 through 8 are formed of highly conductive metal to establish a good connection between the cables 21 connected thereby.
Having thus described the preferred embodiments of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
