Definitions

  • the invention relates to a method for producing a housing according to the Preamble of claim 1.
  • these are, for example electrical connections of the electronic component via which the electronic Component by means of a connecting element, for example to a Power supply is connected.
  • the invention has for its object a method for producing a Specify housing according to the preamble of claim 1, in which the housing can be manufactured inexpensively with different connections can.
  • connections are first comprehensive Contact element made of a first material. After that it becomes Manufacture of the housing the contact element as an insert with a second Injection molded material, the first material of the contact element with the second material merges.
  • connections of the contact element are formed by lead frames.
  • additional lead frames are extrusion-coated, which the connection between the connectors and the electronic component produce.
  • the lead frames of the contact element and the other lead frames of the housing after the manufacture of the housing, for example by bonding connected with each other.
  • connection point of the lead frame and the other Punched lead frames are connected.
  • the side of the contact elements to be encapsulated is always the same is formed while the side to be connected to the connecting element of the contact element according to the requirements of the preferably removable executed connecting element is formed.
  • first material and second material the same plastic material is used.
  • a last development provides that the contact made via the connections electronic and / or mechanical component arranged in the housing as an electromechanical adjusting device, in particular as a valve for Exhaust gas recirculation is formed.
  • connection elements to be contacted made possible by the separate Manufacture of the contact elements the manufacture of the housing in large numbers.
  • a cost reduction is achieved primarily by only one Injection mold for the manufacture of the housing must be made.
  • a valve for exhaust gas recirculation essentially consists of an electromechanical one Actuator, which is arranged in a housing, the connections for contacting the electromechanical actuator. These connections are usually formed by a lead frame, can also of contact wires of an electronic component or are formed by contact areas of a circuit arrangement. Valves for Exhaust gas recirculation is manufactured in large numbers and to various Delivered to customers. Thereby, to adapt the connections to customer-specific Connection elements made different contact elements, which the Include connectors on the chassis.
  • the housing and the contact elements are made of the same plastic, for example PBT GF 30.
  • a selection of contact elements 4.1, 4.2, 4.3 is shown in FIG different on one side, according to the connection element of a customer, are formed, and which are formed on the other side in the same way are.
  • the contact elements 4.1, 4.2, 4.3 are in a conventional plastic injection molding process been made.
  • the connections are made of lead frames 5 formed in the manufacture of the contact elements 4.1, 4.2, 4.3 by the Plastic were overmolded.
  • On the side of the Contact elements 4.1, 4.2, 4.3 are two circumferential contact elements 4.1, 4.2, 4.3, fine plastic seams 6 formed. These fine plastic seams 6 ensure during the manufacture of the housing 1 when injecting the hot plastic mass that the fine plastic seams 6 melt and themselves connect with the hot plastic of the housing 1, making a reliable tight connection is formed.
  • the contact elements 4.1, 4.2, 4.3 are used to manufacture the housing 1 in an injection mold used as recesses next to the space for one of the Contact elements 4.1, 4.2, 4.3 has the space for the housing 1.
  • lead frames 2 are used in the mold, which the form electrical contacts for the electromagnetic actuator 3, and which after the manufacture of the housing 1 with the lead frame 5 of the respective Contact element 4.1, 4.2, 4.3 are connected.
  • the housing 1 is shown, in which a contact elements 4.3 and other lead frames 2 are cast.
  • the contact element 4.3 is at least on the all-round, fine plastic seams insoluble with the Housing 1 fused.
  • FIG. 3 shows the housing 1 and the three possible contact elements 4.1, 4.2, 4.3 shown in a sectional view.
  • the always the same trained side of the Contact elements 4.1, 4.2, 4.3 is surrounded by the material of the housing 1 and at least fused to the plastic seams 6 with it.
  • the lead frame 5 and other lead frames 2 are shaped so that they If possible, do not interfere with the incoming plastic.
  • the lead frames 5 and the other lead frames 2 can first be shaped in this way be that during the manufacture of the housing 1 by the injection mold of the Housing 1 are guided and held. After the housing 1 from the The lead frame 5 and the further lead frame were removed from the injection mold 2 shortened if necessary and bent to connect.
  • FIG. 4 shows the housing 1 and the three possible contact elements 4.1, 4.2, 4.3 also in a sectional view, the lead frame 5 and the other Lead frame 2 are interconnected by a bond 7.
  • the Junction of the lead frame 5 and the other lead frame 2 and thus the bond 7 are advantageously covered by a seal 8.
