Description of the Preferred Embodiment Referring now to the drawings, the connector assembly of the present invention is identified at 21 in Figures 1 and 2. It comprises a hollow armored cable 23 which carries a bundle of electrical leads 25, the forward portion of which extend out of the cable 23 and are connected to an electrical connector 27. The cable 23 is a commercially available bendable or flexible member formed of a helically wound wire strip. The connector 27 may be either a male or female connector with the individual wires of leads 25 connected to its male pins or female sockets respectively. The cable 23 has an annular fitting 29 connected to its end, typically by welding, soldering or crimping. The fitting 29 is described in detail in United States Patent No. 4,295,672. The fitting 29 comprises a forward large diameter portion 29A and a rear smaller diameter portion 29B with a shoulder 31 formed therebetween. A tubular body 33 having an opening 35 formed therethrough has exterior threads 37 and 39 formed on its forward and rear ends respectively.
The threads 37 of the tubular body 33 are screwed to interior threads 40 of the connector 27 when the body 33 is in an assembled position such that the body 33 surrounds the forwa:rd portion of the leads 25 with its rear end 33A
forward of and near the forward end 29C of the fittings 29. The minimum diameter of the opening 35 is large enough such that the body 33 may be unscrewed from the connector 27 and moved rearward of the fitting 29 to a position around the cable 23. A split ring 41 comprising two half ring members 41A and 41B is provided in combination with a nut 43 for securely holding the fitting 29 and hence the cable 23 when the device is assembled.
The ring 41 comprises a forward smaller diameter portion 44 and a larger rear diameter portion 45 with a shoulder 47 formed therebetween. The nut

43 is a cup shaped member with a larger inside diameter opening 51 and a smaller inside diameter opening 53 with a surface 55 formed therebetween.
Interior tllreads 57 are formed in the wall of the nut 43 defining the larger - 3a -85~
opening 51 and are adapted .o be screwed to the threads 39 of the tubular body 33. The diameter of the opening 53 is large enough to freely receive the cable 23 but is smaller than the diameter of the enlarged portion 29A of the fitting 29.
In assembling the device, the tubular body 33 is moved forward around the forward portion of the leads 25 and the threads 37 of the tubular body 33 are screwed into the threads 40 of the connector 27. The split ring members 41A
and 41B are located around the leads 25 with their forward portions 44 inserted within the opening 35 of the tubular member 33 such that the rear end 33A of the tubular member 33 engages their shoulders 47. The rear ends 49 of the ring members 41A and 41B engage the forward end 29C of the fitting 29. The threads 57 of the nut~ 43 are screwed to the threads 39 of the tubular body 33 until the surface 55 of the nut 43 engages the shoulder 31-of the fitting 29. In this assembled position, the fitting 29 is securely held between the end 33A of the tubular body 33 and the ring 41 and the surface 55 of the nut 43.
In the disassembly of the device, the nut 43 is unscrewed from the tubular body 33 and moved rearward. The connector 27 and tubular body 33 then can be moved forward relative to the fitting 29 ciue to the flexibility of the leads 25 allowing the split ring members 41A and 41B to be removed from the opening 35 o~ ~h~ tubula-l boày 33 and then moved transversely away from the leads 25. The body 33 then can be unscrewed from the connect:or 27 and moved rearward of the fitting 29.
This allows the wires of the leads 25 to be exposed so that the pins or socket members of the connector 27 can be readily inserted or removed from the connector 27 for assembly or disassembly purposes.
Figs. 5 and 6 disclose another embodiment of a ring member which may be used in lieu of the split ring 41 in the event that the bundle of leads 25 is relatively small. In this embodiment, the ring member 61 comprises a washer _5 ~ZZ485~
having a slot 63 formed through one side forming a C-shaped member. The slot 63 is large enough to allow the bundle of wires 25 to pass through the slot 63 from the central opening 64 outward and vice versa. In cross section, the C-shaped member 61 comprises a forward smaller diameter portion 65 and a rear larger diameter portion 67 with a shoulder 69 formed therebetwe~n. In assembly, the forward end of the tubular body 33 is screwed to the connector 27. The member 61 is located around the leads 25 by inserting the leads 25 through the slot 63 to the central opening 64 and the smaller diameter portion 65 inserted within the opening 35 of the tubular member until the rear end 33A of the tubular member 33 engages the shoulder 69. The rear end 61A of the member 61 then will engage the forward-end 29C of the fitting 29.
The nut 43 then is screwed to the rear end of the tubular body 33 until the shoulder 55 engages the shoulder 31 of the fitting 29. In the disassembly of the device, the nut 43 is unscrewed from the tubular body 33 and moved rearward. The connector 27 and tubular member 33 then are moved forward relative to the fitting 29 allowing the member 61 to be removed from the opening 35 of the tubular body 33. The member 61 then can be moved transversely away from the leads 25.
