Definitions

  • This invention relates to an a ⁇ icle for protecting multi-conductor connectors, methods of making such articles, and methods and assembly kits for using such article to protect such connectors.
  • a first aspect of the present invention accordingly provides an article for protecting a multi-conductor connector, comprising a housing containing sealant material and having at least two separate or hinged-together sections adapted to be brought together laterally around, and secured to enclose, a portion of the connector and a portion of conductors extending from the connector and beyond the housing in use, wherein
  • a portion of the housing is adapted to engage a portion of the connector enclosed by the housing in use, thereby securing the housing to the connector
  • the housing is constructed to be capable, when secured as aforesaid of pressing the sealant material into sealing contact with the enclosed portions of the conductors (and preferably also of the connector).
  • the conductors (which term may include light conductors as well as electrical conductors) will normally extend beyond the protective housing of the a ⁇ icle according to this invention.
  • the form of the conductors is not critical to the invention it will usually be the case that the conductors carry a protective and/or insulating coating, except where this has been striped away at the end of the conductors for connection to the connector. It will usually be desirable for the housing to enclose and protect all the exposed conductive po ⁇ ions of the connector and conductors, for which purpose the sealing contact of the sealant material will normally extend on to the protective and/or insulating coating of the conductors within the housing.
  • the housing have at least two sections "adapted to be brought together laterally around a po ⁇ ion of the connector and a po ⁇ ion of the conductors" will be understood to mean that the housing can be assembled to surround the connecting po ⁇ ion of a connector with the conductors already in place, without having to place the protective a ⁇ icle over a free-end of the conductors and slide it along to reach the housing. It is uncommon to provide this "wraparound" type of assembly for the relatively rigid protective shell a ⁇ icles used to protecting multi-conductor connectors.
  • the sections of the housing may be hinged together as indicated above, in which case the free-ends of the hinged sections will be brought together to wrap the housing around the connector and conductors and the ends will be suitably fastened together.
  • the housing section may be initially separate from each other and may be fastened at both ends after bringing them together to surround the relevant pans of the connector and conductors.
  • the fastenings may be of any convenient kind, preferably a manually-operable clipping mechanism, especially a snap fit connection. Three or more sections may be used, but two are usually preferred in practice.
  • the sealant material preferably a gel a hereinafter described, may be applied to the connector and/or the conductors before the housing is brought together to surround them, but the sealant is preferably carried in one or more of the housing sections for easy assembly .
  • a second aspect of this invention provides an a ⁇ icle for protecting a multi- conductor connector, comprising a housing adapted to be secured to the connector to enclose a po ⁇ ion of the connector and a po ⁇ ion of conductors extending from the connector and beyond the housing in use, wherein the housing carries sealant material and has an aperture through which the conductors can be arranged to extend and has closure means (preferably hinged to the housing) adapted to be closed over at least pan of the aperture with the conductors extending therethrough in use, and the housing is constructed so that such closing of the closure means is capable of pressing the sealant material into sealing contact with the enclosed po ⁇ ions of the conductors (and preferably also of the connector).
  • the said aperture having the closure means will preferably be in an end wall of the a ⁇ icle which faces toward the connecting po ⁇ ion of the connector when the housing is secured to the connector in use.
  • the sealant material may be pre-applied to the connector and/or the conductors, but is preferably carried by the housing, in which case it is especially preferably for the closure means, for example a separate or hinged lid for the said aperture, to carry at least some of the sealant material which will thus be brought into contact with the conductors upon closing of the said closure means.
  • a third aspect of the present invention provides an a ⁇ icle for protecting a multi-conductor connector, comprising a housing adapted to be secured to the connector to enclose (a)a po ⁇ ion of the connector and (b) a po ⁇ ion of conductors extending from the connector and beyond the housing in use and (c) sealant material present within the housing, wherein the housing is constructed so that, when thus secured, it presses the sealant material into sealing contact with the enclosed po ⁇ ions of the conductors (and preferably also of the connector), and expansion- compensating means is provided which in use can be deformed by thermal expansion of the enclosed sealant material and can recover resiliently on thermal contraction of the enclosed sealant material to continue pressing it into the said sealing contact.
  • expansion- compensating means can accommodate the thermal expansion of the sealant material without permanently removing some of it from the protective enclosure, as tends to happen when the expanded sealant is exuded from the housing, for example, along the trailing conductors which extend beyond the housing.
  • the expansion- compensating means may be arranged in any convenient way to resiliently press the sealant material back to maintain the sealing contact on thermal contraction of the sealant, and this may either involve keeping all of the sealant within the enclosure with means for expanding and contracting at least pan of the enclosure, or receiving the expanding excess of the sealant material into a connected resilient enclcsure from which it is fed back into the main enclosure on thermal contraction.
  • the sealant may either fill the whole of the housing, or may be confined to a selected po ⁇ ion of the housing where it is desired to locate the sealing contact. As with the previous two aspects of the invention, the sealant may be pre-applied to the connector and/or conductors, but is preferably carried by the housing for convenient installation.
  • the deformation of the expansion-compensating means by thermal expansion of the sealant material according to the present invention means a significantly greater deformation that the slight flexing of relatively rigid walls of a protective cap, such as that described in the aforementioned EP-A-0299797, which are not intended to compensate for such expansion.
  • the expansion-compensating means according to d e present invention will preferably be a clearly distinguishable structure additional to or incorporated in the housing, or may for example be a po ⁇ ion of the housing wall which is observably distended by the expansion of the sealant material and resiliently recovers on contraction of the sealant material.
  • One suitable form of expansion- compensating means comprises at least one corrugated po ⁇ ion of the housing, preferably arranged to provide a resilient bellows action.
  • the corrugations may run in any convenient direction, for example parallel with the trailing conductors, but are preferably arranged to provide the resilient bellows action by means of at least one circumferential groove or corrugation extending around d e trailing wires.
  • Such a bellows action will tend to involve movement of the end wall of the housing, through which the conductors extend, along the conductors in a direction away from the connector on expansion of the sealant material and back toward the connector on contraction. This movement will be acceptable, provided that the sealant material is not left behind on the conductors to any unacceptable extent during the contraction stage.
  • sealant material which has a cohesive strength which is greater than its adhesion to the conductors and connector
  • the sealant material preferably being a gel of liquid-extended polymeric material having an elongation to break greater than 200% and substantially elastic recovery from elongation of at least 200% .
  • gels which are the preferred sealant material for all aspects of the present invention, will be further described hereinafter.
  • expansion-compensating means comprises a spring inside or outside the housing arranged to urge a contact member resiliently against the sealant material, the contact member being an integral pan of the housing or a separate member movable within the housing or at least pa ⁇ ly within an aperture in the housing.
  • a spring inside or outside the housing arranged to urge a contact member resiliently against the sealant material, the contact member being an integral pan of the housing or a separate member movable within the housing or at least pa ⁇ ly within an aperture in the housing.
  • Such an internal or external spring might, for example, be arranged to press resiliently against a diaphragm or a resilient wall po ⁇ ion of the housing or to press or pull a slidable plug member within an aperture contained within a wall section of the housing.
  • the spring will be arranged outside d e housing, or at least in a pan of the housing where it avoids contact with the sealant material, since such contact might interfere with the action of the spring.
  • expansion-compensating means comprises at least one snap-invertable indentation in the housing which can be snapped from an inwardly-convex position to an outwardly-convex position by thermal expansion of the sealant material and can snap back to an inwardly-convex position on thermal contraction of the sealant material.
  • Such snap-invertable indentations resemble the well-know children's toys which emit a clicking sound on flexing of a metal strip to cause snap inversion of a (usually circular) indentation in the strip.
  • the housing according to the present invention could be designed to enable the increasing pressure of the thermally expanding sealant material to cause the snap-inversion of a suitable indentation, which would snap back to its original position as the pressure became sufficiently reduced by thermal contraction.
  • expansion-compensating means comprises a body of resilient material, preferably foamed polymeric material, widiin the housing.
  • a body of resilient material might, for example, be in direct contact with the sealant material, or could act as a resilient suppo ⁇ for a flexible diaphragm or other movable member within the housing.
  • the preferred foamed polymeric material will be selected to have a density, compression force, and resilience to suit d e expansion and contraction forced encountered in die housing in use.
  • the sealant material is preferably carried by d e housing as aforesaid, before die housing is placed to enclose die said portions of the said connector and the conductors; and die sealant material is preferably confined within the housing to a position enabling it to fit against an end portion of die connector to be enclosed by the housing in use.
  • a body of die sealant material especially the aforementioned preferred gel, may be moulded into die housing with a suitable former to place the sealant for contact with the part of the connector which it will seal against in use.
  • a separate suitably- shaped block of d e sealant material could be provided as an alternative, for pre- positioning in the housing on the connector and conductors before the housing is placed to enclose them.
  • Pre-positioning of the sealant material could also be effected by wrapping a tape or strip of suitable material around the conductors, and this could, if desired, include wrapping the sealant material into contact with a relevant portion of the connector.
  • the sealant material in any of the aspects of this invention is the preferred gel, it may for example comprises cross-linked polysiloxane material or other cross-linked polymeric material, or hard block-rubbery block-hard block triblock copolymer material (cross-linked) or not.
  • the flexibility and elongation of the preferred gels enables them to accommodate a wide range of wire sizes and variations in the number of wires to be accommodated within a given size of protective enclosure.
  • the cohesive strength of d e adhesive gels being greater ian their adhesion to the conductors and the connector, advantageously enables them to separate cleanly from the conductors and connector on re-opening of the protective enclosure, which may in practice may be desirable for alteration or repair of die connections.
  • the cohesive strength also enhances the retention of the gel widiin the enclosure and die return of the gel to maintain effecting sealing contact after thermal expansion and contraction, which would tend to express a less-cohesive sealant permanently out of d e enclosure.
  • the term gel means any liquid-extended polymer composition having the aforementioned ultimate elongation has measured by ASTM D412 as described, for example, in die aforementioned EP-A-0299797.
  • the gel may preferably have a cone penetration value (measured by a modified version of ASTM D217 as also described in EP-A-0299797) within the range of 30 to 400 (10 " ' mm).
  • the term gel is used to cover compositions mat are sometimes known as geloids and die gel may eimer contain three-dimensional cross-linked molecular formations (gels) or may merely behave as if it contains such molecular formations (geloids).
  • any suitable gel can be used, silicone gels being preferred for use at elevated temperatures, with or wid out an internal suppo ⁇ member as described in EP-A- 0108518 (MP0838).
  • Thermoplastic block copolymer gels which may be useful at suitable temperatures include the styrene-hydrogenated rubber-styrene block copolymer gels described in WO-A-8800603 (RK308), WO-A-9305113 (RK451), and WO-A-9323472 (RK469).
  • the disclosures of the four aforementioned EP- and WO-specifications are inco ⁇ orated herein by reference.
  • the housing has an internal lip engagable with an external formation on mat portion of the connector lo be enclosed by the housing to secure the housing to the connector.
  • Such engagable lips and suitable formations on connectors are known, for example from the aforementioned EP-A-0299797.
  • the engagement preferably substantially prevents removal of the housing from the connector, at least without damaging or opening the housing, and it will appreciated that such a lip engagement is readily and conveniently effected by the wrap-around forms of the article according to the first aspect of the invention hereinbefore described, for example when die housing sections comprise two half-shells.
  • the housing sections may be securable together by means of at least one snap-fit connection between a first formation carried by one of die sections and a second formation earned by another of the sections.
  • the lip engagement may also be used with other forms of the present invention, for example where the housing has a substantially closed perimeter and is adapted to be slid onto, preferably snap fitted onto, d e portion of the connector to be enclosed thereby in use.

Numbering in these Figures 4 to 6 omerwise corresponds to diat in Figures 1 to 3.
  • Wraparound protective articles of die kind generally illustrated by Figures 1 to 6 could, if made of suitably flexible materials, be secured together before subsequently snap-fitting them on to the connector, but it is usually preferred to position them around the lip of the connector before snap-fitting the half-shells together.

  • These half-shells have corrugations (34) which flex and recover to accommodate the diermal expansion and contraction of die gel (not shown) in use. This expansion and contraction will tend to produce a "bellows" action in die corrugations, causing the outlet end (35) of d e housing to move to and fro along the conductors (36) as indicated by the double- headed arrow in Figure 9.
  • FIGs 10 to 14 show a single-piece injection-moulded snap-on article (40) according to diis invention secured to a connector 41 of similar design to those mentioned before with an aperture (42) in the end wall of the article having hinged closure flaps (43) carrying gel sealant material (44).
