Definitions

  • This invention relates to a method of producing an electrical connector of the plug or socket type.
  • a single- or multi-contact connector comprising a housing, a single-part or multiple-part contact insert disposed in the housing, and at least one contact residing in the contact insert and fixed by the latter in axial and radial directions is known from German Patent Application 27 02 827. Connectors of this kind are used particularly in the industrial and military areas, but are employed also wherever great reliability, hermiti- city and little susceptability to interference are paramount.
  • the known connector has a contact insert whose diameter is considerably smaller than the inside diameter of the housing.
  • a method of producing an electrical connector comprising a housing, a contact insert disposed in the housing, and at least one electrical contact disposed in the contact insert, characterized in that the contact insert is formed of a plastic material and ultrasonically welding said contact insert to the housing to thereby connect the contact insert to the housing.
  • a method of producing an electrical connector comprising a housing, a contact insert disposed in the housing, and at least one contact disposed in the contact insert, characterized in that a recess is provided in an inner wall of the housing adjacent to the contact insert and a shoulder is provided on the insert adjacent to the recess, and including the steps of inserting a plastifiable plastic element into the recess and abuting against the shoulder, and ultrasonically welding the plastic element to both the housing and the contact insert to join the housing and the contact insert.
  • an electrical connector comprising a housing, a contact insert disposed in the housing, and at least one electrical contact disposed in the contact insert, the improvement comprising the contact insert being formed of a plastic material and being ultrasonically welded to the housing to connect the contact insert to the housing.
  • an electrical connector comprising a housing, a contact insert disposed in the housing, and at least one electrical contact disposed in the contact insert, the improvement comprising a recess in an inner wall of the housing adjacent to the contact insert and a shoulder. on the insert adjacent to the recess, and a plastic element inserted into the recess and abuting against the shoulder, the plastic element being ultrasonically welded to the contact element and the housing to join the contact element and the housing.
  • the contact insert is formed of plastic and is joined to the housing by means of an ultrasonic welding process.
  • An alternative process comprises inserting a thermoplastic element by ultrasonic welding into recesses provided on the contact insert and/or housing to join the contact insert to the housing.
  • the plug connector shown in Fig. la includes a housing 1, a contact insert 2, a contact retaining plate 3 and a pin contact 4.
  • housing 1 is so designed at its inner bearing surface 5 which contacts the contact insert that joining of the contact insert material, plastified during the welding process, is possible.
  • the bearing surface 5 may be roughened.
  • a plastic with thermoplastic properties should be selected as the contact insert material, i.e., a material which is plastically deformable when heated by ultrasound.
  • Fig. lb shows an alternate embodiment which includes housing 1 of a plug connector, with a contact insert 6, a pin contact 4 and a contact retaining plate 7 disposed in it.
  • housing 1 Provided in housing 1 is a recess 8, opposite which is a shoulder 9 in contact insert 6. To join both parts together, a thermoplastic ring 10 is introduced into the housing in the annular hollow space formed by the recess 8 and the shoulder 9 and is plasticized by ultrasound.
  • Ring 10 adapts to the hollow space, thereby forming a connecting element 11 between housing 1 and contact insert 6.
  • This connecting technique has the advantage that any desired material can be chosen for both the housing and the contact insert because welding one of the parts to the thermoplastic ring 10 is not necessary. If the contact retaining plate 7 is to be fastened ultrasonically at the same time also, this is possible in simple manner by prolonging the length of ring 10 so that a recess 12 of the contact retaining plate 7 is also filled with the plastified compound.
  • the thermoplastic material is plastified by the ultrasonic method in fractions of seconds; as such, assembly of these plug connectors requires little time.
  • FIG. 2 another embodiment of the invention is shown which includes a known plug connector design, for example, a round miniature connector with many contacts, although only one is shown.
  • the contact 16 is fastened in an insert 15 and can be taken apart again with a special tool.
  • the insert is inserted into a housing ring 21.
  • Insert 15 is joined to housing ring 21 by means of a plastic ring 22 which is pushed into the space between the insert and the housing ring, plastified ultrasonically and thus caused to adapt to the contours of a part of the said space.
  • the insert 15 can be joined to the housing ring 21 directly by ultrasound. The ultrasound effect plastifies the outer contour of the insert which, due to its being pushed into the housing ring at the same time, adapts to the latter's contour.
  • a shield adapter 13 which, together with a cap screw 14, accommodates at the same time the shielding mesh of the cable.
  • a coupling nut 17 Located on the contact side is a coupling nut 17, by means of which the plug can be fastened to a socket (not shown).
  • a locking ring 19 limits the axial mobility of coupling nut 17, and in addition a spring washer 20 is provided to eliminate play between the socket and the plug connectors.
  • the present invention provides assembly of a connector in a short time and in a simple manner.
