Abstract
A cable splice closure includes a closure body having mating surfaces sealed together. An end seal in the closure has an opening for receiving a cable. The end seal is sealed to the closure body by an adhesive bond. An adhesive injection port is provided in the end seal to communicate an adhesive injected into the end seal and to bond into a sealed unit the surf aces of the end seal and the cable to be received. The adhesive is a low surface energy adhesive based on acrylic monomers with organoborane amine complexes.
Claims32
A cable splice closure comprising:
- a closure housing formed of a low surface energy plastic material and having mating surfaces to be sealed together;
- an end seal body connected to the closure housing and having an opening for receiving a cable to be extended therethrough, the end seal body being sealed to the closure housing by an adhesive bond;
- and
- an adhesive injection port in the end seal body, the port provided to communicate an adhesive injected into the end seal body to bond surfaces of the end seal and the cable, to be received, into a sealed unit;
- wherein the closure housing has first and second portions, each portion including one of the mating surfaces, and wherein the mating surfaces define multiple seal grooves therebetween, one of the grooves being utilized for initially sealing the mating surfaces together, the one groove being trimmable for permitting reentry into the closure housing, whereby a remaining groove is utilized for resealing the mating surfaces together.

A cable splice closure comprising:
- a closure housing formed of a low surface energy plastic material and having mating surfaces to be sealed together;
- an end seal body connected to the closure housing and having an opening for receiving a cable to be extended therethrough, the end seal body being sealed to the closure housing by an adhesive bond;
- and
- an adhesive injection port in the end seal body, the port provided to communicate an adhesive injected into the end seal body to bond surfaces of the end seal body and the cable, to be received, into a sealed unit;
- wherein a sealing gasket is mounted between the mating surfaces and a plurality of spring clips are connected to the closure for urging one of the mating surfaces into engagement with the other mating surface for compressing the gasket therebetween.

A cable splice closure comprising:
- a closure housing formed of a low surface energy material and having mating surfaces to be sealed together;
- an end seal body connected to the closure housing and having an opening for receiving a cable to be extended therethrough, said opening being defined by an opening surface, said end seal body being sealed to the closure housing by an adhesive bond;
- and
- an adhesive injection port disposed in said end seal body, said injection port adapted to communicate an adhesive injected into said injection port to said opening, thereby bonding said opening surface and the cable into a sealed unit;
- wherein said closure body has first and second portions, each portion including one of the mating surfaces;
- wherein said end seal body is formed in one of the first and second closure body portions;
- wherein said end seal body defines a chamber and an annular opening at each opposite end of the chamber;
- and wherein each of said annular openings includes a sealing washer mounted therein for enclosing opposite ends of the chamber, said washers being trimmable to accommodate various size cables to be extended through said end seal body.
5 more elements
An end seal for a cable splice closure, comprising:
- an end seal body having a slot for receiving a cable to be extended therethrough;
- and
- an adhesive injection port in the end seal body, said injection port adapted to communicate an adhesive injected into the injection port to the cable and surfaces of the end seal adjacent thereto, thereby bonding the cable and said surfaces into a sealed unit;
- wherein said slot comprises a plurality of trimmable concentric washers selectively removable to receive a cable therethrough, and wherein said injection port extends through each of said washers.

An end seal for a cable splice closure, comprising:
- an end seal body having a core portion connected to an extended flexible tail portion, said core portion having an outer peripheral surface and spaced ends, said peripheral surface including a plurality of apertures extending between the spaced ends, each of said apertures being defined by an aperture surface and being adapted to receive a cable;
- and
- an adhesive injection port in said end seal body, said port adapted to communicate an adhesive injected into said port to at least one of said apertures, thereby bonding into a sealed unit the aperture surface of said at least one of said apertures and a cable to be extended through said at least one of said apertures;
- wherein said tail portion has opposed first and second ends, said first end being integral with, and extending tangentially from, said outer peripheral surface and having sufficient length to wrap around said outer peripheral surface in abutment therewith to cover said plurality of apertures, and wherein said tail portion has opposed tail surfaces, each of said opposed tail surfaces having an elongated groove formed therein, each of said elongated grooves extending between said opposed tail ends.

An end seal for a cable splice closure, comprising:
- a core having a slot therein, said slot being adapted to receive a cable and being fitted with a plurality of concentric rings selectively removable to receive a cable therethrough;
- and
- a tail, extending from said core, said tail being of sufficient length and flexibility to be extended over said slot.
An end seal for a cable splice closure, comprising;
- a core having an aperture therein, said aperture being adapted to receive a cable;
- a tail, extending from said core, said tail having a longitudinal groove therein and being of sufficient length and flexibility to be extended over said aperture;
- and
- an adhesive injection port in said core, said injection port being in open communication with said groove.
