Abstract
Abstract An electrical connector including a rigid core having spaced shaped grooves each mounting an elongate resilient member. A flexible strip of insulating material is wrapped around the core. A plurality of spaced apart conductive strips is provided on the strip so that the strips extend circumferentially around the core.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
112 words
An electrical connector including a core comprising at least two resilient elongate members maintained in spaced relationship by a rigid spacing member, a flexible circuit comprising conductive tracks on one surface of a strip of flexible insulating material, the flexible circuit being wrapped around the core so as to cover the resilient elongate members such that the tracks extend substantially circumferentially around the core; a channel having spaced apart walls in the rigid member for receiving the two end regions of the strip; and means separate from the resilient members for simultaneously locking the two end regions of the strip into the channel by pushing the strip end regions against the walls.
Claim 2
Dependent Claim
112 words
An electrical connector including a core comprising at least two resilient elongate members maintained in spaced relationship by a rigid spacing member, a flexible circuit comprising conductive tracks on one surface of a strip of flexible insulating material, the flexible circuit being wrapped around the core so as to cover the resilient elongate members such that the tracks extend substantially circumferentially around the core; a channel having spaced apart walls in the rigid member for receiving the two end regions of the strip; and means separate from the resilient members for simultaneously locking the two end regions of the strip into the channel by pushing the strip end regions against the walls.
Claim 3
Dependent Claim
25 words
An electrical connector as claimed in claim 1, in that the channel is wedge shaped and the locking means is a wedge shaped locking strip.
Claim 4
Dependent Claim
37 words
An electrical connector as claimed in claim 1, in which each of the channels has a recessed part which provides a locking location zone for the locking means, which latter comprises a strip with a circular cross-section.
Claim 5
Dependent Claim
46 words
An electrical connector as claimed in claim 1, in which the channel has a region with a part circular cross-section located intermediate of the depth of the channel and the locking means to a member which is dimensioned to be a snap fit into the region.
