Apparatus with twisting tool having cavities and associated retaining parts for manufacturing electrical harnesses
View Patent ↗The present invention relates to apparatus for manufacturing a harness of electrically conductive wire segments, the apparatus comprising a twisting tool ( 20 ) having at least two cavities ( 31 to 38 ), each cavity being associated with retaining means ( 43, 44 ) enabling at least a portion of a wire segment to be retained in the cavity, release means enabling said wire segment portion to be extracted from the cavity, and opening means ( 46 ) enabling said wire segment portion to be inserted into the cavity.
1. Apparatus for manufacturing a harness of electrically conductive wire segments, the apparatus comprising a twisting tool ( 20 ) comprising a body ( 21 ) and at least two cavities ( 31 to 38 ) each opening out into the outside surface of the body via a peripheral opening ( 42 ), each cavity being associated with retaining means ( 43 , 44 ) enabling at least a portion of wire segment to be retained in the cavity, and also with release means enabling said wire segment portion to be released from the cavity, and with opening means ( 46 ) enabling said wire segment portion to be inserted into the cavity, in which the retaining, release, and opening means comprise a hinged panel extending respectively across the peripheral opening ( 42 ) of each slot, and return means arranged to urge the hinged panel into a closure position.
2. The apparatus according to claim 1 , in which the tool body ( 21 ) is substantially a body of revolution about an axis of symmetry ( 23 ).
3. The apparatus according to claim 2 , in which the tool body is generally in the form of a sphere, a cylinder, or a disk.
4. The apparatus according to claim 2 , in which the tool body presents slots or notches forming said cavities, each slot or notch extending substantially parallel to the axis of symmetry of the body, the body thus somewhat resembling the cylinder of a revolver.
5. The apparatus according to claim 1 , in which the cavities are substantially regularly distributed around the periphery of the body.
6. The apparatus according to claim 1 , in which the tool body has at least four cavities of substantially identical shapes and dimensions, each cavity being suitable for receiving a plurality of wire segments of different sections.
7. The apparatus according to claim 1 , in which the tool body has at least eight cavities of substantially identical shapes and dimensions, each cavity being suitable for receiving a plurality of wire segments of different sections.
8. Apparatus for manufacturing a harness of electrically conductive wire segments, the apparatus comprising a twisting tool ( 20 ) comprising a body ( 21 ) and at least two cavities ( 31 to 38 ) each opening out into the outside surface of the body via a peripheral opening ( 42 ), each cavity being associated with retaining means ( 43 , 44 ) enabling at least a portion of wire segment to be retained in the cavity, and also with release means enabling said wire segment portion to be released from the cavity, and with opening means ( 46 ) enabling said wire segment portion to be inserted into the cavity, in which the retaining, release, and opening means comprise an interrupted ring ( 43 , 44 ) mounted to pivot around the tool body about an axis of symmetry ( 23 ) of the body, and suitable for extending across the peripheral openings ( 42 ) of the cavities.
9. The apparatus according to claim 8 , having two interrupted rings both mounted to independently pivot around the tool body about its axis.
10. The apparatus according to claim 8 , in which the interrupted portion ( 46 ) of each ring presents an arc length ( 47 ) that is less than or equal to the arc length ( 49 ) of the fraction of the periphery of the body associated with one slot or cavity.
11. The apparatus according to claim 10 , in which the length ( 47 ) of the interruption in each ring is substantially equal to the arc length ( 48 ) occupied by the opening ( 42 ) of each slot or cavity.
12. Apparatus for manufacturing a harness of electrically conductive wire segments, the apparatus comprising a twisting tool ( 20 ) comprising a body ( 21 ) and at least two cavities ( 31 to 38 ) each opening out into the outside surface of the body via a peripheral opening ( 42 ), each cavity being associated with retaining means ( 43 , 44 ) enabling at least a portion of wire segment to be retained in the cavity, and also with release means enabling said wire segment portion to be released from the cavity, and with opening means ( 46 ) enabling said wire segment portion to be inserted into the cavity, further comprising a harness support ( 60 ) that is elongate along a longitudinal support axis ( 61 ), together with slider means ( 62 ) extending parallel to said axis and designed to receive a sliding support ( 70 ) for the twisting tool ( 20 ).
13. The apparatus according to claim 12 , further comprising locking means ( 71 ) for holding the twisting tool support in position at any point along the slider means.
14. The apparatus according to claim 12 , further comprising a connector support disposed at a first longitudinal end ( 63 ) of the harness support, a member for securing a connector to the connector support, and a graduated rule ( 76 ) secured to the harness support and extending parallel to the longitudinal axis thereof.
