Definitions

  • the instant invention relates to electrical connectors and methods of manufacturing these connectors.
  • EP-I 296 415 already describes such a connector, which is globally satisfactory. Yet, one always strives to improve the retention and sealing ability of such gaskets in normal use while ensuring easy insertion or removal of the electrical contacting members and maintaining low the risk of damage of the gasket during their insertion/removal .
  • An object of the instant invention is notably to provide such an improvement.
  • the invention provides an electrical connector according to claim 1.

  • - Fig. 3 is a sectional view of a connector according to the embodiment of Fig. 1, in a pre-assembled condition, along line III-III in Fig. 1, - Fig. 4 is a view corresponding to Fig. 3 after insertion of an electrical connection member,
  • Fig. 5 is a view corresponding to Fig. 3 and 4 in the assembled condition of the connector

  • Fig. 7 is a view corresponding to Fig. 6 for a third embodiment of the invention.
  • Fig. 1 is an exploded partial view of an electrical connector 1.
  • This connector comprises a housing 20 made of an electrically insulating material such as glass-fiber reinforced poly-butylene terephtalate (PBT) .
  • the housing comprises a front part 20a arranged in columns and rows of passageways 13, 14 for receiving electrical connection members to be described in further details later on with respect to Fig. 2.
  • the front part of the housing comprises two columns of broad passageways 13, and ten columns of narrow passageways 14.
  • the back portion of the passageways 13, 14 define a back face 28 of the housing for reception of a sealing gasket 2.
  • the housing also comprises a back part 20b, for accommodation of the sealing gasket 2 and of a grid 24.
  • the back part 20b comprises a first set of retention features 15, for example performed as four longitudinal slots extending on the same level in the back part of the housing, two of them being visible on Fig. 1 of the right face of the back part of the housing, and two others being not visible on Fig. 1 and performed symmetrically on the left face of the housing.
  • a sealing device such as a sealing gasket 2 is inserted between the front part 20a of the housing and the grid 24.
  • the sealing gasket 2 is for example made of a soft deformable quasi incompressible material such as Liquid Silicone Rubber.
  • a suitable example could be a material provided by GE-Bayer under reference Silopren 3596/30 (30 Shores A) .
  • the above material also has an auto-lubricating property of 5%, thereby facilitating the contact insertion.
  • HCR Heat Curing Rubers
  • EPDM Ethylene Propylene Diene Monomers
  • EDP thermoplastic elastomers
  • the sealing gasket 2 comprises a front face 2b facing the back face 28 of the housing and an opposing back face 2a facing the grid 24 (Fig. 3) .
  • two series 7, 12 of passageways are defined in the sealing gasket, corresponding to the passageways 13, 14 of the housing.
  • a first series comprises broad passageways 7 of maximal diameter about 3 mm for receiving thick electrical connection members for insertion into broad passageways 13 of the housing, and a second series comprising narrow passageways 12 of maximal diameter about 1 mm for receiving thin electrical connection members for insertion into small passageways 14 of the housing.
  • the back face 2a of the sealing gasket 2 further comprises compression recesses 16. For example, these extend longitudinally between two consecutive rows of passageways.
  • a first recess 16 extends between a first and second row of narrow passageways, and a second recess extends between a third and fourth rows of narrow passageways .
  • the grid 24 is made of a rigid plastic body which will in the assembled condition of the connector, be mechanically connected to the housing, to compress the sealing gasket between the housing and the grid. It also comprises broad passageways 17 and narrow passageways 18 which correspond to the passageways 7, 12 of the sealing gasket, and 13, 14 of the housing.
  • the grid 24 comprises a front face 29 facing the back face 2a of the sealing gasket. In the first embodiment, the front face 29 of the grid comprises compression features which face the recesses 16 of the sealing gasket.
  • the compression features are for example performed as ribs 19 of a shape similar to a shape of the recesses 16, for example of a triangular cross section and which extend longitudinally on the front face 29 of the grid between rows of passageways.
  • the grid 24 comprises, on its sides, mechanical retention features 23 for example in the form of tabs 23 which are elastically deformable with respect to the body of the grid. The tabs 23 are located so as to cooperate with the slots 15, 25 of the first and second set for mechanical retention of the grid in the housing.
  • the dimensions of the sealing gasket, the number of ribs and the number, positions and sizes of passageways of the gasket, of the grid and of the housing depend on the application required for the connector.
  • the dimensions, positions and sizes pictured on Fig. 1 are only exemplary and could vary from one connector to another.
  • an electrical contact member 4 such as the one shown on Fig. 2 comprises a contact portion 22 inserted into a passageway 13, 14 of the front part 20a of the housing, for connection with a mating male contact.
  • the contacts to be inserted in the broad passageways 13 have a somehow rectangular section of 2.40 millimetres (mm) times 2.70 mm. Contacts to be inserted in the narrow passageways are of similar shape, but with a smaller cross section.
  • Fig. 3 is a sectional view of the sealing gasket along the insertion direction, along line III-III of Fig. 1.
  • the axisymmetric passageways 12 extend axisymmetrically about a symmetry axis from the back face 2a of the sealing gasket to the front face 2b of the sealing gasket.
  • the electrical connection member is to be inserted from the top of Fig. 2.
  • the passageways 12 can be sealed by a sealant membrane 26.
  • the sealing gasket 2 rests sensibly uncompressed, on the back face 28 of the front part of the housing. Further, the sealing gasket rests with its upper portion on a complementary shoulder 27 of the housing.
  • the grid is placed in pre-assembled condition, as shown on Fig. 3. In this condition, the retention tabs 23 of the grid cooperate with the upper retention slots 25 of the housing. In this pre-assembled condition, the ribs 19 of the grid 24 extend at least partially into the recesses 16 yet, without compressing the sealing gasket.
  • the electrical contact members 4 are inserted into position, as shown in Fig. 4.
  • the right face 19a of the left rib 19 will mechanically cooperate with the facing right face 16a of the sealing gasket at the left recess 16 to limit the displacement to the left of the sealing gasket 2.
  • the ribs 19 are totally inserted into the recess 16 of the sealing gasket in order to impart a lateral compression (transversal to the insertion direction) on the sheath 6 of the electrical connection member.
  • This will improve the lateral retention of the sheath.
  • the shape of the recesses 16 will be defined a little bit narrower than the shape of the ribs 19, so that material of the sealing gasket is compressed upon full insertion of the rib 19 into the recess 16. This comes in addition to the vertical compression of the sealing gasket between the back face 28 of the housing and the front face 29 of the grid.
  • a fist set of ribs 19 are formed in the front face of the grid 24 for cooperation with recesses 16 in the back face 2a of the sealing gasket, and a second set of ribs 19 are formed in the back face 28 of the housing for facing with corresponding recesses 16 of the front face 2b of the sealing gasket 2.
  • the ribs 19 of the grid and the ribs 19 of the housing are located so as to remotely face each other.
  • compression features in the present examples were exemplified as longitudinal ribs inserted into longitudinal recesses, the invention could also be applied with other types of compression features such as features which apply an uniformly radial pressure on the sheath.
