Definitions

  • the present invention relates to a connecting header for electrical apparatus. More precisely, the present invention relates to a header for electrical apparatus allowing electrical connection of the latter to an electrical connector.
  • the invention also relates to a method for the manufacture of such a header.
  • Headers of this type are used at the interface between the internal electrical elements of electrical apparatus and a connector which is to be connected to this electrical apparatus. They are used, for example, in electrical systems, in particular, in end effector members, where they form the interface between the internal electrical contact zones of the end effector members and the connectors serving to supply them with power.
  • the headers are generally elements of the casing of the electrical apparatus designed to be mounted thereon to form a closed assembly.
  • the problem is therefore to provide a header for electrical connection between, on the one hand, an electrical apparatus and, on the other hand, an electrical connector designed to cooperate with this apparatus.
  • such a header comprises a certain number of substantially flat electrical coupling zones, forming electrical contacts and designed to cooperate with the same number of coupling zones on a connector provided for connection to the header.
  • Each of the contacts is connected in turn to one or more flat electrical contact zones designed to be connected to internal elements of the electrical apparatus.
  • the role of the header is therefore to ensure electrical connection between the internal elements of the apparatus and the electrical contacts of the connector together with geometric transition between the corresponding contact and coupling zones.
  • a complementary role of the header is to ensure, in certain cases, that a plurality of internal elements of the apparatus designed to be connected to a single contact of the connector are brought to the same electrical potential.
  • amperages which have to be transmitted by the header are generally high, which means that the electrical connections in the headers have to be of a large section.
  • these electrical connections are produced by means of contact tabs 1 cut from a metallic sheet and then folded along a plurality of lines in order to arrive at the desired geometric shape, allowing the angular geometric transition mentioned above.
  • the section of the contact tabs 1 is selected as a function of the amperage to be transmitted.
  • the contact tabs 1 thus prepared are then overmolded with a body (not shown in Figure 1) having a geometry allowing, on the one hand, the connection of a connector as mentioned above and, on the other hand, mounting to the casing of the electrical apparatus, preferably closing the latter.
  • the object of the present invention is to remedy these drawbacks by proposing a header for mounting to an electrical apparatus for connecting the latter to a connector, of the kind comprising several electrical contact tabs each extending in the same general direction of extension, arranged side-by-side and each comprising, at one of its longitudinal ends, a contact zone adapted to be electrically connected to the electrical apparatus, and, at the other of its longitudinal ends, a coupling zone for coupling with a complementary contact means of the connector, the contact zones together forming a comb for electrical connection to the connector, characterized in that the contact zones and the coupling zones of each of the contact tabs are connected to each other by a transition zone twisted about its general direction of extension such that the plane of electrical contact of the contact zone of each of the contact tabs is differently oriented to the plane of electrical contact of the coupling zone of that contact tab.
  • the overmolded body preferably presents, on its face designed to bear the coupling zones, a geometry complementary to that of the connector designed to be connected thereto and, on the face designed to be in contact with the casing of the electrical apparatus, means of fixing the header thereon.
  • These fixing means may for example be holes for fastening screws, or a geometry allowing the header to be force-fitted on the casing.
  • the invention also provides an electrical apparatus preferably taking the form of an end effector member and making use of such a header.
  • the invention also relates to a method for the manufacture of a header such as described above, comprising the following steps:
  • the method additionally comprises the following steps, optionally in combination:
  • the steps involving shaping of the contact tabs by twisting and/or by swaging may take place after the overmolding step. Furthermore, the steps involving shaping by swaging and removal of the bridges are optional.
  • a header 10 according to the invention comprises a set 30 of electrical contact tabs 31 (Fig. 2) disposed so as to be parallel overall and held by overmolding in a body 20 (Fig. 3), the header 10 being designed to be mounted to an end 42 of a casing 41 of an electrical apparatus 40 (Fig. 5) to form at this point a termination closing said casing 41.
  • Each of the contact tabs 31 exhibits, at one of its longitudinal ends, at least one flat contact zone 32 adapted to be connected electrically to the electrical apparatus 40 and, at an opposite end, a flat coupling zone 33 for coupling to a complementary connector (not shown).
  • the contact tabs 31 of the header 10 have a twisted transition zone 34 between the coupling zones 33 and the contact zones 32 of each of the contact tabs 31, thus enabling them to extend respectively in a differently oriented plane in the longitudinal direction of the contact tabs 31.
  • the contact zone 32 and the coupling zone 33 of each of the contact tabs 31 are connected to one another by the transition zone 34, which is twisted such that each of the coupling zones 33 and the contact zones 32 are oriented differently relative to the vertical, in the general direction of extension of each of the contact tabs 31.
  • the contact tab 31 takes the form of an L whose shorter branch forms two adjacent contact zones 32a and 32b extending in two horizontal parallel planes, thus allowing two different internal elements of the electrical apparatus 40, which would respectively be in electrical contact with the contact zones 32a and 32b, to be brought to the same potential.
  • the planes of the contact zones 32, 32a, 32b are parallel to one another.
  • the electrical contact between the contact zones 32, 32a and 32b and the internal elements of the electrical apparatus 40 may be achieved by welding.
  • one of the contact tabs 31 visible in Figure 2 exhibits the contact zones 32 and the coupling zones 33 connected by a bridge.
  • the planes of the coupling zones 33 are all oriented at 90° to their direction of alignment A visible in Figure 2.
  • the set 30 of the contact tabs 31 is held in the body 20, which is overmolded on the contact tabs 31, so as to leave free the contact zones 32 and the coupling zones 33.
  • the body 20 has at sides thereof two holding lugs 22, each provided with an aperture 23 for the passage of a screw for fastening the connector (not shown) on the header 10.
  • the body 20 On the face designed to cooperate with the connector (not shown), the body 20 has an extension 21 configured to protect the electrical coupling zones 33 (not visible in Figure 3).
  • the shape of the extension 21 and its position relative to the coupling zones 33 are determined in such a way that it can cooperate with the connector (not shown), which is designed for connection to the header 10.
  • the body 20 On the face designed to cooperate with the casing 41 of the electrical apparatus 40, the body 20 has guides 24, dimensioned so as to provide a force fit with an opening (not visible in the Figures) provided for this purpose in the casing 41 of the electrical apparatus 40.
  • the guides 24 thus participate in holding the header 10 on the casing 41 of the electrical apparatus 40.
  • the contact tabs 31 are obtained from a single piece, visible in Figure 4.
  • the unworked piece in the form of a comb is cut, for example by stamping, from a sheet of conductive metal.
  • the various chamfers at the ends of said piece, visible in particular in Figure 4, may advantageously be formed during the same operation.
  • the comb-like design makes it possible to optimize utilization of the sheet metal serving in manufacture of a base 36 so as to reduce material waste.
  • the contact tabs 31 are connected together at a center thereof by substantially aligned bridges 35 forming the base 36.
  • the contact zones 32, 32a and 32b are shaped so as to extend in planes parallel to the plane formed by the base 36. This shaping may be effected by swaging, for example. This swaging may be combined with the initial cutting stage effected by stamping.
  • the contact tabs 31 are then twisted by 90° about their direction of longitudinal extension in such a way that the contact zone 32 and the coupling zones 33 of each of the contact tabs 31 extend respectively in planes oriented differently relative to the vertical, in the longitudinal direction, to correspond with the connector (not shown) used.
  • This twist may be applied for example by a tool adapted to impart a twist to the contact tab 31 and applied thereto in the coupling zone 33.
  • the twist is imparted to each of the contact tabs 31 along their longitudinal axis and results in plastic deformation of the transition zone 34.
  • angular shaping of the contact tabs 31 may take place in parallel on one and the same comb, which represents a gain in productivity.
  • the body 20, made of insulating material is overmolded on the semi-finished part visible in Figure 4 using a conventional overmolding method. Removal of the bridges 35 follows, for example by cutting, so as to eliminate short-circuits between the contact tabs 31.
  • removal of the bridges 35 may be effected prior to overmolding.
  • the finished header 10 is mounted to the end 42 of the casing 41 of the electrical apparatus 40 to form a termination therefor.
  • the contact zones 32, the coupling zones 33 of the header 10, and those of the connector are aligned substantially along parallel straight lines.
  • the electrical apparatus 40 is here an end effector member of an electrical system.
  • the header 10 closes the casing 41 of the electrical apparatus 40, while forming a termination allowing connection of the electrical apparatus 40 to a corresponding electrical connector (not shown).
  • the guides 24 of the body 20 effect a force fit with the end 42 of the casing 41.
  • the contact zones 32, 32a, 32b of the header 10 are welded to contact zones 43 of electrical elements 44 of the electrical apparatus 40.
  • the parallel horizontal planes of the contact zones 32, 32a and 32b correspond respectively to the planes of the contact zones 43 of the electrical apparatus 40 in such a way that the contact zones 32, 32a, 32b of the header 10 and the contact zones 43 of the electrical apparatus 40 are closely superposed once the header 10 has been mounted on the casing 41, thus facilitating welding of the contact zones 32, 32a, 32b, 43.
  • Electrical spot welding may advantageously be used.
