Definitions

  • the instant invention relates to an electrical connector and to an electrical connector assembly.
  • the instant invention is related to an electrical connector adapted to be mounted on a circuit board comprising: a housing including:
  • positioning arm projecting transversely and rearwardly from the rear face, said positioning arm having a lower supporting surface adapted to be mounted on the upper surface of the circuit board;
  • At least one contact receiving-through aperture extending from said rear face to the front face; at least one electrical contact fitted into said through aperture, said at least one electrical contacts having a first section extending along a first symmetry axis and a second section extending along a second symmetry axis, said first and second symmetry axis forming a 90° angle.
  • Such connectors are for example known from right angle D-Sub connector.
  • board-mounted electrical connectors have been attached to the surfaces of circuit boards on which other electronic or electrical components are mounted.
  • the market trend for this kind of connector runs towards more compact and slim electrical connectors, this is particularly important since the cabinets, which usually contain such connectors, are becoming smaller.
  • such a connector is characterized in that the housing includes a lower edge situated below and beyond said lower supporting surface provided with a ledge formed within a portion of the thickness from the rear face towards the front face, said ledge extending perpendicularly to and below the lower supporting surface of the positioning arm and extending over a distance corresponding substantially to the length of the housing thereby forming a recess for accommodating a circuit board portion.
  • the connector is further characterized in that a portion of the first section of the electrical contact fitted into the housing comprises an asymmetric shape providing an available space adapted to receive the front portion of the circuit board.
  • the connector of the present invention is particularly interesting for cabinet applications, since for a same available room, it is possible to use the connector with circuit boards having larger dimensions. Accordingly, a denser circuit board packaging is achievable.
  • the connector according to the present invention may be mounted on thicker circuit board in a same available space of a cabinet .
  • the invention relates to an electrical connector assembly according to claims 5 to 7.
  • Fig. 1 is a sectional view along plane P of Fig. 2;
  • Fig. 2 is an elevation front view of an embodiment of a connector
  • - Fig. 3 is an elevation rear view of the connector of Fig. 1;
  • Fig. 4 is a top partial view of a connector assembly comprising the connector of Fig. 2 and 3.
  • Figure 1 shows a sectional view along plane P of the connector represented in Fig. 2.
  • the connector 1 is for connection to a circuit board 2 (Fig. 4), for example of the D-subminiature type.
  • the connector 1 includes an insulating housing 3 having a thickness along a first transversal direction Tl, a length along a second transversal direction T2, a height
  • the housing 3 has a front face 3a, on which are assembled front shielding elements, and a rear face 3b. Said housing 3 is pierced with through apertures for insertion therein of electrical contacts.
  • the connector housing according to the present invention is 25 mm height, with a length of about 40 mm and a thickness of about 2.4 mm.
  • these electrical contacts may be of two types: electrical power contacts 4 and electrical signal contacts 5.
  • Electrical power contacts are of large dimension, over 8 millimetres (mm) in diameter and for example of diameter about 10 mm, for transmitting electrical power to and/or from the circuit board.
  • Electrical signal contacts are of lower diameter for transmitting signal to and/or from the circuit board. The number of electrical power and signal contacts on the drawings is purely by way of example.
  • the housing 3 comprises two stages of through-apertures adapted for receiving an upper and a lower power contact 4.
  • Each power contact 4 comprises a first contact section 4a, provided with a mating end 6, extending along a first symmetry axis 7 and a second section 4b, provided with a connection end 9, extending along a second symmetry axis 10.
  • the first contact section 4a is joined to the second section 4b by a curved portion 10 so as they are mutually perpendicular providing a right angle contact.
  • the power contact 4 as shown in Fig. 2 and 3 has a generally rounded shape and is provided with a flange 11, located on its first section 4a, which abuts the rear face 3b of the housing 3 when it is inserted therein.
  • a portion of the first section 4a is fitted into the through aperture of the connector housing 3, while its mating end 6 protrudes from the front face 3a.
  • the portion of the upper power contact engaged into the housing is substantially symmetric with respect to its first symmetry axis 7.
  • the lower stage power contact has substantially the same general shape as the upper power contact but it differs in that its housing engaging portion comprises an asymmetric shape. More precisely, the lowermost part of said contact portion has been shaped to provide a lower flattened face 12 which extends substantially parallel to the first symmetry axis 7. In this example this truncated shape corresponds, in section, to the shape of a cylinder intersected by a plane running parallel to the longitudinal axis of the cylinder.
  • the housing 3 further comprises mechanical positioning features 13 of the connector 1 onto the circuit board 2.
  • such retention features are positioning arm projecting transversely and rearwardly from the rear face 3b of the insulating housing 3.
  • Each of said positioning arms 13 presents a lower supporting surface 14 designed for resting on the upper surface of the circuit board 2 when the connector is in place.
  • said positioning arms further includes retention features.
  • the retention features are provided as a series of parallel tongues 15 extending vertically downward for snapping into complementary holes forming complementary retention features 16 provided in the circuit board 2.
  • the housing 3 has a lower edge 17 positioned below and beyond said lower supporting surface 14 and is further provided with a ledge 18 formed within a portion of the thickness from the rear face 3b towards the front face 3a. Said ledge 18 is situated below and extends perpendicular to the lower supporting surface 14 of the positioning arm 13, so as the lower edge 17 of the housing forms a flange portion 19.
  • the flange portion formed by the lower edge of the housing abuts against the front edge 22 (Fig. 4) of the circuit board 2 with its front part received within the clearance provided by the ledge 18. Consequently, more surface area of the circuit board 2 can be provided on the circuit board; the surface area gain substantially corresponds to space set free by the ledge 18.
  • the connector of the present invention could be mounted on a circuit board having more available surface area, thus providing a more compact cabinet architecture.
  • This contact shape feature also contributes to propose a denser cabinet architecture wherein circuit boards are placed one above another. Indeed, height reduction of the connector could advantageously be turned to profit for the connection with circuit boards having an increased thickness, i.e. having a greater number of embedded conductive tracks.
  • the connector 1 is assembled with the circuit board 2 such that the first retention features 15 cooperate with the complementary retention features 16 of the circuit board.
  • the connector 1 is assembled with the circuit board 2 such that the first retention features 15 cooperate with the complementary retention features 16 of the circuit board.
  • only one electrical power contact 4 and signal contact 5 is shown inserted into corresponding parts 20, 21, respectively of the circuit board 2.
  • the lower supporting surface 14 of the front face 3b of the housing 3 comes into contact with the edge 22 of the circuit board 2, for better retention thereto. It should be noted that it is only sufficient to design a cut out in the circuit board of a width corresponding to the length w of the connector and of depth d sensibly corresponding to the thickness t of the lower edge of the housing, i.e. in the present example : 2.4 mm.
