Abstract
Abstract An electrical contact member comprises a conductive plate (4) having therein a slot (5) open to an edge of the plate (4), the slot (5) having a mouth (28) at the edge of the plate (4) and leading to a first inwardly tapering section (29) which leads to a second parallel straight sided section (30), the second section (30) leading into a third inwardly tapering section (31) having convex converging sides leading to a throat (32) which opens into a fourth outwardly tapering section (33) leading into a fifth inwardly tapering section (34) having convex converging sides, the maximum width of the fifth section (34) being less than that of the third section (31), the fifth section (34) defining a closed end (35) for the slot (5). When used with a conductor (100) having a stranded core the slot shape of the contact serves to retain the strands in as near as possible their original relative positions, thus ensuring reliable connection.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
An electrical contact member comprising a conductive plate having therein a slot open to an edge of the plate, the slot having a mouth at the edge of the plate and leading to a first inwardly tapering section which leads to a second parallel straight sided section, the second section leading into a third inwardly tapering section having convex converging sides leading to a throat which opens into a fourth outwardly tapering section leading into a fifth inwardly tapering section having convex converging sides, the maximum width of the fifth section being less than that of the third section, the fifth section defining a closed end for the slot.
Claim 2
Dependent Claim
109 words
An electrical contact member comprising a conductive plate having therein a slot open to an edge of the plate, the slot having a mouth at the edge of the plate and leading to a first inwardly tapering section which leads to a second parallel straight sided section, the second section leading into a third inwardly tapering section having convex converging sides leading to a throat which opens into a fourth outwardly tapering section leading into a fifth inwardly tapering section having convex converging sides, the maximum width of the fifth section being less than that of the third section, the fifth section defining a closed end for the slot.
Claim 3
Dependent Claim
17 words
A contact member as claimed in claim 1, in which the first section has converging straight sides.
Claim 4
Dependent Claim
18 words
A contact member as claimed in claim 1, in which the fifth section terminates in an enlarged aperture.
Claim 5
Dependent Claim
25 words
A contact member as claimed in any preceding claim, in which the sides of the second section are bevelled to provide relatively sharp cutting edges.
Claim 6
Dependent Claim
33 words
An electrical contact comprising two contact members as claimed in claim 1, in which the slots in the two contact members are of mutually different widths over their second, third and fourth sections.
Claim 7
Dependent Claim
31 words
An electrical contact as claimed in claim 5, in which the two contact members are joined by two bridging strips extending between the plates on opposite sides of the slots therein.
Claim 8
Dependent Claim
114 words
An electrical connector comprising a housing of electrically insulating material carrying a plurality of electrical contact members each as claimed in claim 6, in which the housing includes a cover member which serves to urge conductors into the slots in the contacts and then remain secured to the housing body covering the connections between the contacts and the conductors, the cover member being formed with a plurality of stuffer members which serve to engage the conductors to urge them into the slots in respective contacts, and which remain in contact with the conductors thereby serving to retain the conductors in the slots in the respective contacts and mechanically secure the conductors to the connector.
Claim 9
Dependent Claim
35 words
A connector as claimed in claim 7, in which the cover member is formed with latching means which co-operates with latching means on the housing body to latch the cover member to the housing body.
Claim 10
Dependent Claim
36 words
A connector as claimed in claim 7, in which each conductor connected thereto is gripped between stuffer members on the cover member and surfaces formed on the housing body, on each side of the associated contact.
Claim 11
Dependent Claim
39 words
A connector as claimed in claim 7, in which the cover member is formed with three stuffer members for each contact, the stuffer members for each contact being arranged to embrace the plates of the contact between pairs thereof.
Claim 12
Dependent Claim
38 words
A connector as claimed in claim 7 or claim 10, in which the bridging strips of each contact engage over shoulders formed on the housing body to support the contact in the associated cavity in the housing body.
Claim 13
Dependent Claim
50 words
A connector as claimed in claims 7, in which the housing body has a plurality of cavities each containing an individual contact, the cover member being formed by a plurality of segments each for receipt in an individual cavity in the housing body, the segments being joined by web portions.
Claim 14
Dependent Claim
47 words
A connector as claimed in claim 12, in which one end of each segment of the cover member is formed with a channel to receive a conductor connected to the contact associated with that segment, the conductor being bent through a right-angle to extend in the channel.
Claim 15
Dependent Claim
26 words
A connector as claimed in claim 13, in which the channel is formed with inwardly directed projections which serve to secure the conductor in the channel.
