Definitions

  • the invention relates to a connector for a flat conductor, for example a flexible printed circuit (FPC) or a flexible Flat cable (FFC), and in particular for flat cable harnesses using several, spaced connectors are provided, such as for example bus connections.
  • a connector for a flat conductor for example a flexible printed circuit (FPC) or a flexible Flat cable (FFC)
  • FPC flexible printed circuit
  • FFC flexible Flat cable
  • Connectors for flat conductors are generally known.
  • An acquaintance Type of connector consists of two connector halves that are on the side the flat conductor is pushed on and then pressed together, whereby they lock together in an end position.
  • contact elements designed like insulation-piercing clamps, which insulation of the flat conductor when the connector halves are pressed together cut through to make electrical contact with the leads to form the flat conductor.
  • Another type of connector must be used a free end of the flat conductor is inserted into a connector housing in this way that stripped free ends of the electrical wires of the Protrude flat conductor in corresponding contact sockets, which in the Connector housings are provided.
  • the invention has for its object to provide a connector which can be easily mounted on a flat conductor and which Handling of a flat conductor provided with several connectors simplified.
  • the connector according to the invention has a first connector part and second plug part, which by means of a snap or snap connection can be put together and each have a guide channel for the Have flat conductor, which is in the direction of insertion of the plug contact a rear area of the connector parts to a front face of the Plug parts extends through the plug parts.
  • both connector parts each have a guide channel have, which extends essentially through the entire plug part extends, a mounted flat conductor runs through each connector part.
  • the connector is therefore not necessarily an end connector, in which a free end of the flat conductor must be inserted, but it can be mounted on the flat conductor without cutting the flat conductor must become. This makes the connector particularly suitable good for mounting on a continuous flat conductor.
  • the two connector parts can also be snap-fitted assemble quickly and safely in a simple way. This makes it easier the final assembly of the connector.
  • the connector parts are in a pre-assembly state of the connector arranged one behind the other, wherein the front end faces of the connector parts point towards each other.
  • the connector parts one behind the other shows the connector in Preassembly state to a low overall height.
  • Multiple connectors can be stored or transported in a space-saving manner. are several connectors already mounted on a flat conductor, so made possible the pre-assembly condition makes rolling up easy and space-saving of the flat conductor, which simplifies the packaging of the flat conductor becomes.
  • the connector parts By arranging the plug parts one behind the other, a Passing the flat conductor through the connector parts will be easier. Thereby, that the front end faces of the connector parts each face each other point, the connector parts can also be around an imaginary axis, that between the front faces across the guide channels runs, fold over, bring into contact with each other on the back and assemble using the snap or snap connection. The front End faces of the plug parts then both point in the plugging direction of the connector.
  • a distance of the front facing one another in the pre-assembled state End faces of the connector parts can be chosen so that a between the Section of a connector part through the guide channels running flat conductor in the assembled state on the front End faces of the connector parts. This ensures that the flat conductor is tight around the front of the connector runs and there does not form a loop that the space required by the Connector increased or damage to the flat conductor could lead.
  • the connector parts are at least in a pre-assembly state of the connector via at least one Connection bridge connected to each other.
  • the connecting bridge provides a correct distance between the two connector parts and in particular between the front faces facing each other the connector parts safely.
  • the connecting bridge prevents that a plug part of a loose connector can be lost.
  • the connecting bridge can either be flexible so that it can be bent when the plug parts are folded, or it can be rigid be so that it breaks when the connector parts are folded over.
  • the connector parts are in the Area of their guide channels molded onto the flat conductor.
  • the connector parts can be molded on in a particularly simple manner attach the flat conductor.
  • the injection can be done quickly and inexpensive to carry out and is also particularly suitable good for mounting multiple connectors on a continuous flat conductor.
  • the connector parts can each be in one piece and in particular as injection molded parts be formed, or the connector parts and at least one connecting web can be integral with one another and in particular as one Be injection molded part. In both cases, the connector can be in this way with a particularly low economic outlay produce.
  • a plug part has contact openings on contacting exposed portions of electrical Allow lines of a flat conductor in the area of the guide channel.
  • the connector consequently does not have its own contact elements, i.e. there is no need to equip connector parts with contact elements. Thereby is the number of process steps to manufacture the connector or a flat cable set with one or more connectors reduced and thus the corresponding manufacturing costs reduced.
  • the connector parts can each have a half base in their rear area have, the half-base in the assembled state form a handle base.
  • the handle base makes handling the Connector improved.
  • Another object of the invention is a method for manufacturing a flat conductor with at least one connector one of the previous training, in which a flat conductor with at least a first and second connector part is provided, the connector parts in a pre-assembled state of the plug contact in the direction of the longitudinal extent of the flat conductor one behind the other along the flat conductor be arranged so that the front end faces of the connector parts point to each other.
  • the individual connector parts are in the pre-assembled state of the connector with the flat conductor essentially in one plane.
  • a flat conductor with connectors in the pre-assembled state is therefore particularly easy Roll up easily and space-saving, which means that the packaging of the Flat conductor cable set is simplified and on the other hand the transport security is improved. Due to the pre-assembly condition of the connectors is also prevented that, for example, during a removal of the flat cable set from its packaging, the individual Hook connectors together. In addition, at the process take advantage of all the advantages that already exist above have been explained in connection with the connector.
