Abstract
Abstract An article for protecting a multiconductor connector comprising a container containing a layer of gel. In one embodiment the container can be moved relative to the container to compress the gel to seal the connector. In another embodiment the gel layer contains a plurality of holes which tend to close when the gel is compressed.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
136 words
An article for protecting a multiconductor connector having a plurality of contacts holes therein for receiving a plurality of contact pins, the article comprising: (a) an open container having a base and sides and; (b) within the container a continuous layer of gel having a cone penetration value within the range of from 30 to 400 (10 -1 mm), wherein: the sides of the open container can be secured in use in first and second positions relative to the multiconductor connector and the base of the open container is adjacent to the gel layer and allows passage of said contact pins and trailing wires therethrough but substantially prevents egress of the gel from the container, wherein at least when the container is secured in the said second position relative to the container the gel is compressed.
Claim 2
Dependent Claim
136 words
An article for protecting a multiconductor connector having a plurality of contacts holes therein for receiving a plurality of contact pins, the article comprising: (a) an open container having a base and sides and; (b) within the container a continuous layer of gel having a cone penetration value within the range of from 30 to 400 (10 -1 mm), wherein: the sides of the open container can be secured in use in first and second positions relative to the multiconductor connector and the base of the open container is adjacent to the gel layer and allows passage of said contact pins and trailing wires therethrough but substantially prevents egress of the gel from the container, wherein at least when the container is secured in the said second position relative to the container the gel is compressed.
Claim 3
Dependent Claim
26 words
An article according to claim 1, wherein when the container is secured in the said first position relative to the connector the gel is not compressed.
Claim 4
Dependent Claim
26 words
An article according to claim 1, wherein movement of the base out of the container in the direction away from the layer of gel is limited.
Claim 5
Dependent Claim
22 words
An article according to claim 3, wherein the container sides comprise an inwardly directed lip to limit the movement of the base.
Claim 6
Dependent Claim
18 words
An article according to claim 3, wherein the base is integrally formed with the sides of the container.
Claim 7
Dependent Claim
49 words
An article according to claim 1, wherein when the container is secured to the connector the container sides overlap the edges of the connector, and wherein movement of the container relative to the connector from said first to second position increases the area of overlap of the two parts.
Claim 8
Dependent Claim
26 words
An article according to claim 1, wherein the base comprises a plurality of apertures to allow the passage of the contact pins and trailing wires therethrough.
Claim 9
Dependent Claim
23 words
An article according to claim 7, wherein the apertures in the base correspond to the plurality of contact holes in the multiconductor connector.
Claim 10
Dependent Claim
14 words
An article according to claim 7, wherein the base comprises a rectangular apertured grid.
Claim 11
Dependent Claim
40 words
An article according to claim 1, wherein the container comprises first and second securing means in the form of first and second lips on the sides of the container, which can be secured to a corresponding lip of the connector.
Claim 12
Dependent Claim
40 words
An article according to claim 10, wherein at least the sides of the container comprise a deformable material, the deformability of the container allows the container to be deformed to interengage the lip(s) of the container and the multiconductor connector.
Claim 13
Dependent Claim
27 words
An article according to claim 1, wherein the gel is substantially uniform in thickness, and is at least 2 mm thick, preferably at least 3 mm thick.
Claim 14
Dependent Claim
27 words
An article according to claim 1, wherein the gel has a cone penetration of approximately 30-400 (10 -1 mm) and an ultimate elongation of at least 100%.
Claim 15
Dependent Claim
47 words
An article according to claim 1, wherein the gel is provided as an impregnant comprising a plurality of interconnected segments within a flexible matrix which comprises a plurality of open interstices, the interstices having an average volume of less than 0.01 inch 3 (0.16 cm 3 ).
Claim 16
Dependent Claim
35 words
An article according to claim 1, wherein the container is secured in the second position relative to the connector the gel is compressed at least 40%, preferably at least 50%, more preferably at least 80%.
Claim 17
Dependent Claim
32 words
An assembly comprising an article according to claim 1, in combination with the multiconductor connector, the connector and article being movable towards each other into said second position to compress the gel.
Claim 18
Independent Claim
105 words
A method of protecting a multiconductor connector having a plurality of contact pins, the method comprising: (a) positioning an article according to any preceding claim adjacent the connector so that the sides of the open container are secured in the first position relative to the multiconductor connector; (b) inserting the contact pins and wires frailing from the contact pins through the base and through the gel into the contact holes in the multiconductor connector, and (c) moving the container relative to the connector so that it is in the second position relative thereto and the gel is thereby compressed against the said inserted trailing wires.
