Definitions

  • the invention relates to a plug connection with at least one pin contact and/or at least one socket contact, which is connected to a cable and to a pin or socket housing, the pin or socket contacts being sealed in the pin or socket housing and secured against longitudinal displacement , according to the features of the preamble of patent claim 1.
  • plug connectors are arranged at one end of a cable and have at least one electrical conductor.
  • a contact partner (called contact element or pin or socket contact) is arranged on each electrical conductor, with each contact partner being arranged in a housing, also called pin or socket housing, in particular in a respective contact chamber of the housing.
  • the housing pin or socket housing
  • This sealing element is arranged on the outer cable sheath of the cable, so that this cable sheath faces the housing is sealed and no water can penetrate into the respective contact chambers of the housing.
  • the invention is therefore based on the object of specifying a plug connection which is satisfactory in terms of water tightness. This is to prevent moisture, water or the like from penetrating the housing of the connector via the cable and reaching a contact partner there.
  • each pin or socket contact is assigned a sealing element which encloses the pin or socket contacts, that each sealing element is inserted in a recess of the pin or socket housing and that the sealing elements are designed to be braced.
  • This ensures that the pin or socket contacts are clearly and securely sealed in the pin or socket housing, thus ensuring permanent tightness.
  • Another advantage is that the cross section of the pin or socket contacts is reduced in the area of the sealing elements, so that the sealing elements are set to fit on the pin or socket contacts from the outset.
  • a pressing element is fixed in the pin or socket housing, which pressing element has pressing heads, by means of which the sealing elements can be braced. This pressing element therefore ensures that the sealing elements are permanently braced.
  • the pressing element be designed in the shape of a half-shell and that the pin or socket contacts be insertable into troughs.
  • This half-shell-shaped design of the pressing element is sufficient and represents secure clamping of the sealing elements.
  • the pressing element can be improved by providing two half-shell-shaped pressing elements or one full-body pressing element that encompasses the pin or socket contacts, so that the sealing elements at their complete end faces are pressed.
  • a locking element which is supported on the pin or socket housing, so that the sealing elements are permanently pressed.
  • the locking element is preferably designed like a comb and has comb fingers which can be inserted into openings in the pin or socket housing and the locking element. As a result, the pressing element or elements are firmly supported on the pin or socket housing.
  • the pin or socket contacts have nose-shaped projections that can be supported on the comb fingers.
  • the pressing element has the nose-shaped projections adapted recesses in which the projections are arranged and inserted, so that the pin and socket contacts are fixed in both directions, mating and unmating of connectors.
  • Figure 1 a section through a connector with a plan view of pin contacts
  • Figure 2 an exploded view of the individual components of a
  • the reference number 1 designates sealing elements which are assigned to each pin contact 2 and are inserted into suitable recesses in a pin housing 3.
  • the sealing elements 1 are approximately cylindrical in shape and are made of an elastically flexible or deformable material .
  • the pin contacts 2 are inserted into passage openings in the sealing elements 1 .
  • socket contacts and a socket housing can also be used.
  • the sealing elements 1 are assigned a pressing element 4 which, with pressing heads 9, presses the sealing elements 1 into the recesses, compresses them axially, and thus widens and braces them. Because of the elastic deformability of the sealing elements 1, they nestle against each other to the inner contour of the recesses in the pin housing 3 and the outer contour of the pin contacts 2. As can be seen in FIG. 1, the compressed sealing elements 1 nestle around a portion of the pin contacts 2 and do not interact with the electrical conductor, its cable jacket or a cable jacket of such a cable.
  • the pressing element 4 is designed in the shape of a half-shell and has depressions with which the pressing element 4 at least partially encompasses the pin contacts 2 .
  • Two half-shell-shaped pressing elements 4 or a single pressing element 4, which completely encompasses the pin contacts 2, can also be used.
  • the pin contacts 2 have nose-shaped projections 7 which are aligned in the longitudinal direction of the pressing element 4 transversely to the longitudinal axis of the pin contacts 2 and can be inserted into further troughs of the pressing element 4 .
  • the pressing element 4 is fixed in the pen housing 3 by means of a locking element 5, the locking element 5 having comb fingers 8 which are inserted or pushed into openings in the pen housing 3 and the locking element 5, so that the locking element 5 is fixed in the pen housing 3.
  • the pin contacts 2 are simultaneously fixed in both axial directions on the pressing element 4 and the locking element 5, on the comb fingers 8 thereof.
  • the sealing elements 1 are first pushed in direction A into the associated recesses and fixed there. Then, in a step B, the pin contacts 2 are inserted. Then, in a step C, the pressing element 4 is arranged in the pin housing 3 of the connector, with the insertion of the pressing element 4 compressing the sealing elements 1 . This is done under force so that the force to compress is maintained then the locking element 5 is inserted into the pin housing 3 and thus fixes the pressing element 4 in the pin housing 3, thereby maintaining the force of the pressing element 4 on the sealing elements 1 in the sense of permanent compression.
  • the pin housing 3 which can also be designed as a socket housing, wherein at least the pin housing 3 has an insertion opening 8 for the ends of the pin 3 and / or socket contacts, and the pressing element 4 are shown in section. In practice, for example, they are implemented as closed parts.
  • the pin housing 3 or the socket housing can also consist of two shells, in particular two half-shells, which are assembled into one component.
  • pin housing 3 or the socket housing with an additional outer housing.
  • a further locking element can also be used from the opposite side of the pin housing 3 or the socket housing.
  • the openings in the pin housing 3 or in the socket housing and/or in the locking element(s) for the comb fingers 8 and/or the comb fingers 8 themselves can have bevels which cause that during insertion of the at least one locking element 5 in the pin housing 3 or in the socket housing, a force is applied to the pressing element 4, which causes either only the force for compressing the sealing elements 1 or an additional force for this purpose.
