Definitions

• the present invention relates to an electrical connector device.
• it relates to a sealed protection for electrical contacts in the electrical connector assembly .
• Some known electrical connector devices comprise a connector body having a plurality of cavities each receiving an electrical contact. Electrical contacts are usually provided by an assembly of two complementary parts which are a terminal and a wire. Such assembly is then assembled to the body of the connector. For the terminal and the wire of the electrical contacts, it is necessary to have protection for protecting the assembly region from undesirable effects. This protection can be impaired by the temperature variation and can lead to decreasing of its protection characteristics.
• the protection for an internal member which could comprise one or more elements, should bear the temperature changes and should cover the aforementioned internal member. In particular, when it is necessary to withstand high temperatures, the materials have to keep their initial properties in order to provide proper protection .
• the present invention is for an electrical connector device comprising:
• the tube comprises projections and the sealing member comprises recesses cooperating with the projection.
• the sealing member is pressed in contact both with the internal member and the cavity to provide a peripheral sealing barrier between the internal member and the cavity.
• FIG. 1 is a rear side perspective view of a tube, according to the present invention.
• - Figure 3 is a perspective view of an assembly of the sealing member and the tube according to the present invention
• - Figure 4 is a cross section view of the assembly of the sealing and the tube arranged inside of a contact cavity of a carrier.
• Figure 1 is a rear side perspective view of a tube 10, according to the present invention. As illustrated in Figure 1, the tube 10 extends longitudinally along a longitudinal axis X, and comprises a cylindrical main portion and a rear portion.
• the cylindrical main portion has a ring-shaped constant cross-section about the longitudinal axis X.
• the tube 10 defines an inner passage extending from a front end to a rear end along the longitudinal axis X.
• the rear portion of the tube 10 comprises a rear edge 13 with projections 11 protruding in the rear direction.
• the projections 11 are curved and adapted to the radius of the tube 10.
• the projection 11 comprises a top side 11a, a bottom side lib, an inner side Hi, an outer side llo and side walls lis.
• the top side 11a of the projection 11 is sector shaped, with a corresponding radius of the tube 10 and with a thickness which is not exceeding the thickness of the tube 10.
• the top side 11a of the projection 11 is also connected to an outer side llo of the projection 11.
• the outer side llo of the projection 11 is curved.
• the outer side llo of the projection 11 is conically broadening to a bottom side lib of the projection 11.
• the bottom side lib of the projection 11 is sector shaped.
• An inner radius of the sector of bottom side lib is adapted to the outer surface of the tube 10 and an outer radius of the sector of the bottom side lib is substantially bigger than the inner radius.
• the inner side Hi of the projections 11 is adapted to the inner side of the tube 10 and extends to a top side of the projection 11.
• the outer side llo of the projection 11 connects the outer radius of the sector shaped top side 11a of the projection 11 and the outer radius of the bottom side lib of the projection 11.
• the projection 11 also comprises side walls lis which are on each side of the projection 11 and are connecting the edge 13 of the tube 10 with the inner side Hi, top side 11a, outer side llo and bottom side lib of the projection 11.
• the tube 10 is provided with a plurality of such projections 11 provided at regular intervals along the peripheral direction.
• the tube 10 also comprises a protruding flange 12 arranged on the inner side of the tube 10, as shown on Figure 1.
• Figures 2 and 2A are respectively a rear view and cross section view of a sealing member 20, preferably an annular sealing member 20, according to the present invention .
• the sealing member 20 comprises recesses 24, which are encompassed by a central body 21, preferably a ring shaped central body 21, by a peripheral body 22, preferably a ring shaped peripheral body 22, and by bonding portions 23. Bonding portions 23 are connecting the ring shaped central body 21 and the ring shaped peripheral body 22.
• the peripheral body 22 comprises a collar 26, preferably a rearward facing collar 26.
• the central body 21 defines a passage extending along the longitudinal axis X.
• a central opening 25 of the passage is surrounded by the central body 21.
• the inner side of the central body 21 includes a central protruding portion 21p.
• the protruding portion 21p is ring shaped and protruding to the centre of the central opening 25.
• the peripheral body 22 comprises a peripheral protruding portion 22p.
• the peripheral protruding portion 22p is ring shaped and protruding to the outer side of the peripheral body 22.
• the sealing member 20 comprises an groove 27, advantageously a peripheral groove 27, formed between the central body 21 and the peripheral body 22.
• the peripheral groove 27 makes it possible to insert therein the edge 13 and projections 11 of the tube 10.
• the groove 27 opens into the recesses 24.
• the end of the peripheral incision 27 is not plain.
• a slot 28, preferably an inverse U-shaped slot 28, is denting the groove 27.
• Figure 3 is a perspective view of an assembly of the sealing member 20 and the tube 10 according to the present invention. Particularly, the Figure 3 shows the sealing member 20 and the tube 10 in a rear view.
• the tube 10 is made of rigid material
• the sealing member 20 is made of deformable material .
• Recesses 24 of the sealing member 20 are cooperating with projections 11 of the tube 10.
• the tube 10 forms a rear stop for the terminal 3t in the cavity 4, and the support 2 retains the tube 10 therein. Consequently, the rear end of the tube 10 projects rearward from the sealing member 20 to serve as a rear stop portion to maintain the terminal 3t in the cavity 4.
• the central protruding portion 21p of the central body 21 is pressed to the internal member 3, i.e. terminal 3t and/or the wire 3w, and the peripheral protruding portion 22p of the peripheral body is pressed to the inner wall of the cavity 4 of the carrier 1. Further, the sealing member 20 is pressed overall on the tube 10.
