Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
Fluid-tight electrical connector comprising in combination: an inner cup member having a bottom and side walls defining a chamber holding a plurality of internal electrical contacts and shunt means connecting at least some of said contacts, a cover member provided with apertures for admitting electrical conductors and means for making sealing contact with said conductors when received in said apertures, interfitting snap-fastening means on said inner cup and cover member for attaching said cover member to said cup member, an outer cup member dimensioned to receive said inner cup member, interengaging snap-fastening means on said inner and outer cup members for holding said cup members together when said inner cup member is received in said outer cup member, and locking means on said outer cup member positioned to block separation of the interfitting snap-fastening means on said inner cup and cover member, when said inner cup member is received in said outer cup member with said cover member in place thereon.
Claim 2
Dependent Claim
161 words
Fluid-tight electrical connector comprising in combination: an inner cup member having a bottom and side walls defining a chamber holding a plurality of internal electrical contacts and shunt means connecting at least some of said contacts, a cover member provided with apertures for admitting electrical conductors and means for making sealing contact with said conductors when received in said apertures, interfitting snap-fastening means on said inner cup and cover member for attaching said cover member to said cup member, an outer cup member dimensioned to receive said inner cup member, interengaging snap-fastening means on said inner and outer cup members for holding said cup members together when said inner cup member is received in said outer cup member, and locking means on said outer cup member positioned to block separation of the interfitting snap-fastening means on said inner cup and cover member, when said inner cup member is received in said outer cup member with said cover member in place thereon.
Claim 3
Dependent Claim
55 words
Connector as claimed in claim 1 in which said means for making sealing contact with said conductors is a block of elastic material having portions received in the apertures of said cover member and encircling said conductors, said block being compressed between said inner cup member and cover member when interfitting snap-fastening means are interengaged.
Claim 4
Dependent Claim
72 words
Connector as claimed in claim 1 in which said interfitting snap-fastening means comprise notches in the outer surface of the wall of the inner cup member, and flexible arms having hooked ends carried by said cover member so that said hooked ends engage in said notches, said locking meaNs comprises portions of said outer cup member overlying said hooked arms when said inner and outer cup members and cover are snapped together.
Claim 5
Dependent Claim
30 words
Connector as claimed in claim 1 in which said outer cup member is provided at its bottom with opposed downwardly extending resilient projections adapted to grip therebetween a supporting rail.
Claim 6
Dependent Claim
53 words
Connector as claimed in claim 4 in which said cover comprises a lateral projection having a lower surface inclined with respect to the outer wall of said outer cup member, whereby the exertion of pressure on said lower surface serves to separate said cup members and cover as a unit from said rail.
Claim 7
Dependent Claim
27 words
Connector as claimed in claim 5 in which said lateral projection has a groove receiving one end of a locking means, and slots for receiving a label.
