摘要:
A tubular cable splice housing formed in one piece from tough resilient plastic material slit lengthwise thereof to permit forced opening of the slit for reception of cabling and provided with integral lock means to hold the slit positively closed. A tough highly resilient plastic serves these purposes, the slit including complementally shaped interlocking portions integral with portions of the housing carried by the opposite sides of the slit. The housing preferably includes a charging opening for potting compound and an embracing split sleeve valve rotatable about the housing between the open and closed positions.

A divider clamp assembly having many uses such as isolating reactive potting compound constituents in a flexible walled package assembly until the constituents are ready for use.
摘要:
A kit of components for encapsulating a branchout splice to an installed power distribution cable and the like and a method of installing the components all of which include a longitudinally slit sidewall. The kit includes a resilient tubular splice housing having an interlocking portion and slit elastomeric grommets sealing the cabling to the housing ends. A sleeve valve encircles the housing and closes a potting compound charging port. The kit includes a ductile splice connector having slit tubular passages clenchable about exposed surfaces of cabling conductors to hold them spliced together. Additional slit sleeves serve as adapter grommets for accommodating smaller cable sizes.

A pressure equalizing accessory for electrical cables installable along the upper side of the cable sheath. The accessory includes a tubular fitting anchorable to the sheath at intervals therealong and a downwardly opening U-shaped breather having one leg in communication with the upper end of the tubular fitting and the other end vented to the atmosphere and effective to safeguard against the admission of moisture and liquids generally while providing for free air flow as necessary to maintain equalized pressure conditions.
摘要:
A weather-proof flexible enclosure for electrical test equipment commonly used in the field. The enclosure or casing has a builtin window of flexible transparent material with sufficient excess to permit the user to manipulate, from the exterior thereof, control elements on a panel of test equipment housed in the casing. Loops of strip material secured to the enclosure serve to reinforce the saem as well as to carry and to suspend it in the filed from any convenient support.
摘要:
A capping accessory for hermetically sealing a cable end temporarily or permanently. The accessory is typically molded in one piece from a thermoplastic material sealable to potting compound and preferably includes a locator boss within its inner end as well as a plurality of flexible tangs projecting axially from its open end with their free ends securable to the adjacent surface of a cable assembled into the accessory. Adhesive tape wrapped about the cable in an area intermediate the top and bottom of the accessory aids in centering the cable therewithin as well as acts as an anchor ring to hold the cable against withdrawal from potting compound filling the accessory and surrounding the anchor ring.
摘要:
A reusable multipurpose protective jacket assembly for cable splices including a fluidtight resilient inner plaque and a larger nonstretchable restraining plaque each provided with means for holding the same wrapped about an incomplete splice. The inner stretchable rubber plaque is coated with tacky material readily sealable to the cable sheath and to its uncoated surface to provide a fluid-type bladderlike enclosure for the splice and which is then inflatable with gas from the gas charged cable to safeguard against entry of moisture. The outer plaque provides a restraining shroud to protect and prevent blowout of the rubber bladder. Additionally, the restraining shroud can be suspended between an open splice and a wet manhole wall to shield the splice from the wet wall while splicing is in progress.
摘要:
A grounding assembly for use in completing a high strength solderless connection between conductive means and a grounding conductor supported in the earth, such as a pipe or stake. Either single or multiple solderless terminal units can be held captive adjustably along a single clamping band. The solderless terminal units can also be used alone or in multiple to provide assurance of a better and a higher capacity connection with the ground stake or pipe. These terminal units also include tempered sharp edges in high pressure contact with both the ground wire and the ground stake.
摘要:
A cable-pressure-equalizing accessory having a cup-shaped member fixed to the outer end of a tubular fitting. The latter is equipped with adjustable split ring means for holding the tubular fitting seated in an opening through a cable sheath in a manner excluding moisture and foreign matter while equalizing the internal cable pressure with the ambient pressure.
