Definitions

  • the present invention relates to the field of electrical connectors. It applies in particular to connectors for local networks of companies to strong information flow.
  • the first and second headings respectively group the connectors working at 100MHz and 250MHz. These connectors use cables of four pairs of 100 Ohms, see 120 Ohms, either unshielded or common shielding using metallic plastic tape twisted around the pairs. In some cases, a mass drain is added. Finally, in the best of cases EMC a braid is additionally arranged above the layer banded.
  • the third section brings together the connectors working at 600MHz (1Gbit for local area networks) and capable of going up to 1.3 GHz or more for multimedia applications. It uses cables of four pairs of 100 Ohms see 120 Ohms. These pairs must be shielded separately by through metallic plastic tape. A common shield made up either additional tape, or a braid, or if necessary combination of such additional tape and braid, covers the pairs.
  • connection devices hitherto proposed One of the problems posed by the connection devices hitherto proposed is that the diversity of connectors available today means that, on site, frequently finds incompatibility between connection sets (receptacle / sheet) offered and available.

  • the rear part of the base 100 has preferably the shape of a cross 160 forming a shield respectively between the four pairs of contacts.
  • the cross 160 is formed by two membranes 162, 164 medians perpendicular to each other.
  • this shielding, in rear part of the base 100 is completed by two lateral flanks 165, 166 which respectively extend the two side walls 114, 115 of the front part.
  • the assembly is designed to receive four pairs of electrical contacts.
  • the invention is not limited to this particular provision.
  • the eight contacts 120 are arranged in pairs in four insulators 130 respectively at each corner of the parallelepiped cage 110.
  • the base 100 is thus preferably permanently wired, thanks to the self-stripping contacts 128 with four pairs of cables preferably shielded separately.
  • the rear part of the base 100 receiving the wiring by self-stripping contacts and inserter is mechanically closed and electro-mechanically by a conductive cover (not shown in the figures appended for simplicity of illustration) thus forming four tunnels each housing a pair of contacts, in cooperation with the aforementioned cruciform shield 160.

  • These electrical contacts 220 are adapted to come automatically into support against the electrical contacts 120 of the base 100 when engaging a insert 200 on the latter, while being themselves accessible on the insert 200. As indicated above, the distribution of electrical contacts 220 over the insert 200 is adapted to the arrangement of the connection assembly or plug complementary.
