Abstract

A pair of related plastic blocks 10 and 11 containing mating contacts is protected by a metal shroud 12. The shroud 12 and enclosed block 10 are formed with side slots and notches 13 engaged by vertical webs such as those of the frame member 14. The shroud extends outward as a port to position and support the mating block 11 as it is being assembled.

Connector Block Strain Relief Devices

A pair of related plastic blocks 10 and 11 containing mating contacts is protected by a metal shroud 12. The shroud 12 and enclosed block 10 are formed with side slots and notches 13 engaged by vertical webs such as those of the frame member 14. The shroud extends outward as a port to position and support the mating block 11 as it is being assembled.

Extending wires 15 are clamped between side arms 16 and 17 by a screw 18 pressing against a wedge slide 20. Arm 17 has its outer end formed with upper and lower pilot tabs 21 and bent ledges 22. Arm 16 is formed with a pair of horizontal extensions 23 which end in hook edges 24. These have openings to receive the pilot tabs 21. Each arm 16 and 17 is formed with a bent end 25 fitting into shroud slot 26 and a locking tab 27 to hold it in the assembled position.

The lower left views show how the clamp arm ends are maneuvered into the shroud slots by first hooking tabs 27 and then swinging ends 25 into the shroud slots. As the outer ends of arms 16 and 17 are swung together the hook edges 24 of arm 16 are snapped over the ledges 22 of arm 17.

Slide 20 has a notched guide and wedge portion 28 which fits between arm extensions 23 and slides between them. Screw 18 fits loosely in the ear of slide 20 but is threaded through a tapped hole in arm 16. A blunt end of screw 18 presses against the side of wedge portion 28 and causes it to clamp the wires 15 against the inside wall of the end...
