Abstract

A cable connector assembly for releasably securing a pair of cable portions of a cable together, the cable connector assembly having a stationary housing made up of two outer shell subassemblies, a movable inner shell subassembly slidable within one of the two outer shell subassemblies, and a mounting fixture for securing the stationary subassemblies to a fixed object. One of the cable portions has one end secured to a movable object and the other end secured to the inner shell subassembly. The other cable portion has one end secured to a fixed object and the other end secured to the other of the outer shell assemblies. During normal conditions, the cable portions are securly connected together. Upon the application of a predetermined amount of force to the movable portion of the cable, the inner shell subassembly withdraws from the one outer shell subassembly in order for disconnection of the cable portions to take place in a reliable, safe and efficient manner.

Claims

1. A cable connector assembly for releasably securing together a pair of cable portions of a cable, comprising:

stationary means for fixedly securing therein one of said cable portions during release of said pair of cable portions from one another;

means releasably slidable within said stationary securing means for fixedly securing thereto the other of said cable portions;

means releasably connected to said stationary securing means for fixedly securing said other of said cable portions directly thereto, said means releasably connected to said stationary securing means including a cover-like element and at least one shearable element for releasably connecting said cover-like element to said stationary securing means, said cover-like element capable of being released from said stationary securing means when said shearable element is subjected to a preselected amount of force sufficient to cause said element to shear; and

means included as part of said stationary securing means and said releasably slidable means for releasably connecting said one cable portion to said other cable portion;

whereby, upon the application of said preselected amount of force to said shearable element through said cover-like element and said other cable portion, substantially simultaneously said cover-like element is released from said stationary means, said releasably slidable means is withdrawn from said stationary means and said pair of cable portions disconnect from one another.

2. A cable connector assembly as defined in claim 1 wherein said stationary securing means comprises a first outer shell subassembly and a second outer shell subassembly, one end of said first outer shell subassembly being connected to one end of said second outer shell subassembly.

3. A cable connector assembly as defined in claim 2 wherein said releasably slidable means comprises an inner shell subassembly, said inner shell subassembly being slidably mounted within said second outer shell subassembly.

4. A cable connector assembly as defined in claim 3 wherein said second outer shell subassembly comprises a tubular-shaped member, said tubular shaped member having one end thereof connected to said one end of said first outer shell subassembly, said cover-like element being releasably connected to the other end of said tubular-shaped member, and said other cable portion being secured to said releasable cover-like element.

5. A cable connector assembly as defined in claim 4 wherein said first outer shell subassembly comprises a tubular-shaped member having one end thereof connected to said one end of said tubular-shaped member of said second outer shell subassembly, and said means for releasably connecting said one cable portion to said other cable portion being made of two parts, one of said parts being connected to said one end of said tubular-shaped member of said first outer shell subassembly.

6. A cable connector assembly as defined in claim 5 wherein said inner shell subassembly comprises a tubular-shaped member, and the other part of said means for releasably connecting said one cable portion to said other cable portion being connected to one end of said tubular-shaped member of said inner shell subassembly.

7. A cable connector assembly as defined in claim 6 wherein said inner shell subassembly comprises means for aligning said two parts of said releasable cable connecting means together as well as securing said other part of said releasable cable connecting means to said tubular-shaped member of said inner shell subassembly.

8. A cable connector assembly as defined in claim 7 wherein said tubular-shaped members of both said second outer shell subassembly and said inner shell subassembly have means therein for viewing said releasable cable connecting means as well as relieving any vacuum build up within said second outer shell subassembly during disconnection of said cable portions.

9. A cable connector assembly as defined in claim 8 further comprising means for securing said first and said second outer shell subassembly to a fixed object.
