Definitions

  • This invention relates to electric connectors.
  • Electric connectors having a two-part housing with at least one insulation piercing contact mounted in one part of the housing for connection to a respective insulated conductor, and conductor clamping means formed by or carried on the two parts of the housing spaced lengthwise from the insulation piercing contact or contacts are known (for example, as shown in UK Patent Specification No. 1462920).
  • the conductor clamping means is of such a form that, when the two parts of the housing are moved together to force the conductor onto its respective insulation piercing contact to make an electrical connection to the contact, said clamping means clamp the insulated conductor in such a way that substantially no tensile force is applied to that part of the conductor extending between the clamping means and the insulation piercing contact.
  • the clamping means can also serve as a stress relief device for the electric connector.
  • the conductor clamping means preferably comprises a first shoulder on one part of the housing which co-operates with a second shoulder on the other part of the housing in such a way that, as the two parts of the housing are moved together, the insulated conductor is distorted at two longitudinally spaced positions along its length so that the insulated conductor is gripped between the two shoulders as the conductor is forced onto its respective contact.
  • the connector has two similar co-operating shoulders, one on each part of the housing, positioned on the side of the clamping means remote from the contact or contacts, which shoulders similarly grip the conductor and serve with said first and second shoulders as a strain relief device.
  • the or each insulation piercing contact preferably has two cutting edges between which the insulated conductor is forced, the cutting edges piercing the insulation on the conductor to mkae the electrical connection between the conductor and its contact.
  • the or each insulation piercing contact can comprise a spike which pierces the conductor insulation to make the electrical connection.
  • the arrangement of the electric connector is such that there is one insulation piercing contact for each insulated conductor.
  • the two parts of the housing are preferably hinged together.
  • the two parts can be separately formed but capable of being interlocked together.
  • the invention has the advantage that because no tensile force is applied to that part of the conductor extending between the clamping means and the insulation piercing contact when the two parts of the connector housing are moved together, risk of tearing the conductor and bending of the insulation piercing contact is substantially reduced.
  • the electric connector 1 of part of an electrical detonator circuit shown in Figure 1 comprises a two-part housing 2, two insulation piercing contacts 3 (only one is visible) and clamping means.
  • An electric cable 4 comprising two insulated conductors 5 is shown ready to be fitted to the connector 1.
  • the clamping means comprises an upstanding shoulder 6 of groove 7 in one part 8 of the housing 2 and a co-operating downwardly projecting shoulder 9 of rib 10 on the other part 11 of the housing 2.
  • the two parts 8, 11 of the housing 2 are hinged together.
  • the arrangement is such that when the two parts 8, 11 of the housing 2 are moved together, the cable 4 is clamped at point A ( Figure 2) between the co-operating shoulders 6, 9 as the conductors 5 are forced onto the insulation piercing contacts 3. Clamping of the cable 4 at point A is so effected that further movement together of the two parts 8, 11 of the housing 2 apply substantially no tensile force to those parts of the conductor 5 extending between point A and the insulation piercing contacts 3, and that a tensile force is applied to that part of the cable 4 on the side of point A remote from the contacts 3 to cause that part of the cable to move in the direction X towards point A.
  • Rib 10 has a second shoulder 12 ' which moves into groove 7 to cooperate with a second shoulder 13 on the groove which grips the cable 4 to form the stress relief device. Both the clamping means and the stress relief device distort the cable through an angle of substantially 90° at two spaced positions.
