Abstract
Abstract An insulation displacement terminal comprises a base (20) having a pair of integrally connected side plates (22 and 24) and an integrally connected flex arm (30) disposed between the side plates. The side plates have guide slots (26 and 28) formed in part by inwardly staggered legs (38 and 40). The flex arm has laterally spaced blades (34 and 36) which bias an insulated conductor (52) received in the guide slots against the edges of the inwardly staggered legs of the side plates to establish four-point electrical contact with the core (56) of the insulated conductor under the constant pressure of the flex arm.

Claim 1
Independent Claim
223 words
An insulation displacement terminal comprising a base (20) having a pair of laterally spaced side plates (22 and 24) integrally connected thereto, each of the side plates (22 and 24) having a guide slot (26, 28) and the guide slots (26 and 28) in the respective side plates (22 and 24) being aligned with one another for receiving an insulated conductor parallel to its axis, and a blade-like member (30) integrally connected to the base and disposed between the slotted side plates (22 and 24), characterised in that the bladed member comprises a flex arm (30) having laterally spaced blades (34 and 36) adjacent the respective side plates (22 and 24), and the side plates (22 and 24) are formed with corresponding insulation-piercing edges (42 and 44) flanking the respective guide slots (26 and 28), in an arrangement in which the introduction of an insulated conductor (52) into the guide slots (26 and 28) of the side plates (22 and 24) causes the blades (34 and 36) of the flex arm (30) to pierce the insulation of the insulated conductor (52) and to bias the insulated conductor (52) against the corresponding insulation-piercing edges of the guide slots (26 and 28), to establish four-point contact with the core (56) of the insulated conductor (52) under the constant contact pressure of the flex arm (30).
Claim 2
Dependent Claim
223 words
An insulation displacement terminal comprising a base (20) having a pair of laterally spaced side plates (22 and 24) integrally connected thereto, each of the side plates (22 and 24) having a guide slot (26, 28) and the guide slots (26 and 28) in the respective side plates (22 and 24) being aligned with one another for receiving an insulated conductor parallel to its axis, and a blade-like member (30) integrally connected to the base and disposed between the slotted side plates (22 and 24), characterised in that the bladed member comprises a flex arm (30) having laterally spaced blades (34 and 36) adjacent the respective side plates (22 and 24), and the side plates (22 and 24) are formed with corresponding insulation-piercing edges (42 and 44) flanking the respective guide slots (26 and 28), in an arrangement in which the introduction of an insulated conductor (52) into the guide slots (26 and 28) of the side plates (22 and 24) causes the blades (34 and 36) of the flex arm (30) to pierce the insulation of the insulated conductor (52) and to bias the insulated conductor (52) against the corresponding insulation-piercing edges of the guide slots (26 and 28), to establish four-point contact with the core (56) of the insulated conductor (52) under the constant contact pressure of the flex arm (30).
Claim 3
Dependent Claim
162 words
An insulation displacement terminal according to claim 1, characterised in that each of the side plates (22 and 24) has a leg (38, 40) on one side of the respective guide slot (26, 28) which is staggered inwardly towards the leg (38, 40) of the other side plate (22, 24) and is formed with an insulation-piercing edge (42, 44) as aforesaid, the laterally spaced blades (34 and 36) of the flex arm (30) comprise parts of a U-shaped portion (32) of the flex arm (30) at its free end, and the laterally spaced blades (34 and 36) have insulation-piercing edges (46 and 48) that are effective to pierce the insulation of an insulated conductor (52) as aforesaid and additionally to bias the insulated conductor (52) against the insulation-piercing edges (42 and 44) of the side plates (22 and 24), which edges (42 and 44) are formed on staggered legs (38 and 40) on one side of the guide slots (26 and 28).
Claim 4
Dependent Claim
32 words
An insulation displacement terminal according to claim 2, characterised in that the laterally spaced blades (34 and 36) biasingly engage the staggered legs (38 and 40) of the side plates (22 and
Claim 5
Dependent Claim
31 words
24) to ensure proper positioning of the flex arm (30) for receipt of an insulated conductor (52) in the guide slots (26 and 28) of the side plates (22 and 24).
Claim 6
Dependent Claim
31 words
24) to ensure proper positioning of the flex arm (30) for receipt of an insulated conductor (52) in the guide slots (26 and 28) of the side plates (22 and 24).
Claim 7
Dependent Claim
66 words
An insulation displacement terminal according to any one of claims 1 to 3, characterised in that one (22) of the side plates (22 and 24) has a stop tab (50) extending inwardly towards the other (24) of the side plates (22 and 24), for limiting movement of the flex arm (30) away from the guide slots (26 and 28) in the side plates (22 and 24).
