Abstract
Abstract The connector comprises an insulated housing (50) (see Figure 5) and contact members (15) housed in recesses (52) therein. Each contact member (15) is formed by U-bending a slotted blank (10) (see Figure 1) and has aligned insulation displacement slots (13) (see Figure 1) and a spade terminal receiving slot (14) in its bend. The insulation displacement slots (13) are relatively wide mouthed (as at 17) and taper to a narrow section (23). Tooth-like projections (21) are provided on opposite sides of the entrance to the narrow sections (23) of the slots (13) for piercing the insulation (35a or 35b) (see Figures 3 and 4) of a conductor introduced into these slots. τhe contact members have protrusions (25) adjacent the narrowed sections (23) of the slots (13) to slightly widen and strengthen the slots (13) and to act to separate the insulation (35a or 35b).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
70 words
A contact member for an electrical connector having an insulation displacement slot (13) therein defining opposed edge surfaces (13') for providing electrical connection to an insulated conductor (33a or 33b), the slot having a mouth (17) leading to a relatively narrow section (23) characterised by at least one tooth (21) projecting into the slot (13) for piercing the insulation (35a or 35b) of a conductor (33a or 33b) introduced therein.
Claim 2
Dependent Claim
70 words
A contact member for an electrical connector having an insulation displacement slot (13) therein defining opposed edge surfaces (13') for providing electrical connection to an insulated conductor (33a or 33b), the slot having a mouth (17) leading to a relatively narrow section (23) characterised by at least one tooth (21) projecting into the slot (13) for piercing the insulation (35a or 35b) of a conductor (33a or 33b) introduced therein.
Claim 3
Dependent Claim
26 words
The contact member of claim 1 wherein the tooth (21) is positioned intermediately between the mouth (17) and the narrow section (23) of the slot (13).
Claim 4
Dependent Claim
31 words
The contact member of claim 1 or 2 having two teeth (21) projecting into the slot and wherein the teeth are positioned in juxtaposed relationship on opposite sides of the slot.
Claim 5
Dependent Claim
54 words
The contact member of claim 1, 2 or 3 wherein the contact member adjacent the narrow section of the slot is formed with a protrusion (25) projecting outwardly from a major surface of the contact member thereby increasing the width of the narrow section (23) of the slot in the region of the protrusion.
Claim 6
Dependent Claim
26 words
The contact member of claim 4 having a second protrusion (25) and wherein the protrusions are positioned in juxtaposed relationship on opposite sides of the slot.
Claim 7
Dependent Claim
33 words
The contact member of any preceding claim wherein the slot defines a pair of limb portions (26) and the limb portions are deformable away from each other upon introduction of a conductor therebetween.
Claim 8
Dependent Claim
48 words
The contact member of claim 6 wherein the limb portions are each formed with a free end (27) and taper to a relatively narrow width at their free ends (27) thereby enabling the limb portions to deform along substantially their entire length upon introduction of a conductor therebetween.
Claim 9
Dependent Claim
47 words
The contact member as claimed in any preceding claim in which the contact member has spaced apart first and second ones of said insulation displacement slots (13) such that contact is made with a conductor inserted into the contact member at two slightly spaced apart points therealong.
Claim 10
Dependent Claim
11 words
The contact member as claimed in claim 8 of generally U-shape.
Claim 11
Dependent Claim
44 words
The contact member as claimed in claim 9 formed by bending a metal blank (10) having said first and second insulation displacement slots (13) at opposite ends thereof such that the two ends with their respective slots adjoin one another in the final U-shape.
Claim 12
Dependent Claim
67 words
The contact member as claimed in claim 9 or 10 in which an elongate slot (14) is provided generally in line with the two slotted ends of the contact member in the region of the bight or U-bend of the contact member such that the bight or U-bend of the contact member is effectively divided or bifurcated to receive a spade or other compatible terminal member (59).
Claim 13
Dependent Claim
47 words
An insulation displacement connector comprising an electrically insulating connector housing (50) having one or more recesses (52) therein and each receiving a contact member as claimed in any preceding claim, each such recess being open at its end corresponding to the mouth end of the contact member.
Claim 14
Dependent Claim
46 words
An insulation displacement connector as claimed in claim 12 in which the open end of the or each recess corresponding to the mouth end of the connector member is formed for directing and guiding a conductor inserted therein into the mouth of the associated contact member.
Claim 15
Dependent Claim
42 words
An insulation displacement connector as claimed in claim 13 in which the or each recess includes strain relief formations (62) which are displaced by a conductor (33) inserted into the connector and then resile to hinder or prevent withdrawal of the conductor.
Claim 16
Dependent Claim
99 words
An insulation displacement connector as claimed in claim 13 or 14 in which the or each recess receives a contact member as claimed in claim 8, 9, 10 or 11 and the open end of the or each recess is formed with opposed pairs of grooves (55) into which the edges of the two insulation displacement parts of the contact member engage and a pair of ribs (56) of triangular cross-section disposed one on either side of the pairs of grooves the ribs being tapered at their upper ends to provide guidance for a conductor introduced into the recess.
Claim 17
Dependent Claim
75 words
An insulation displacement connector as claimed in claim 13, 14 or 15 in which the or each recess is open at both ends and receives a contact member as claimed in claim 11 the open end of the recess at its end opposite its open end corresponding -to the mouth end of the contact member providing access for a spade or other compatible terminal member (59) to engage the bifurcated part of the contact member.
