Definitions
- the invention relates to a crimp contact of a flexible foil conductor with at least a conductor path defined on an insulating support layer, wherein the area to be contacted of the conductor track defined on the film in one crimped compressed part is arranged, which in the unmolded state at least two directly opposite each other, one leg U-shaped having protruding cheeks.
- Foil conductor with electrical fixed to an insulating support layer Tracks are known.
- film conductors with several insulated conductors as electrical connection lines between electrical components used are used.
- the advantages of these foil conductors are in particular in their low height and their low weight.
- Crimp contacts for film conductors are already known, for example from the CH-PS 585 975 or US-PS 5,137,468 which is considered to be the closest prior art.
- the from CH-PS 585 975 and the US-PS 5,137,468 known crimp contacts of flexible film conductors are in Contrary to the conventional crimp contacts of stranded conductors not very reliable.
- the crimp contact of CH-PS 585 975, the tips of the crimping pushed through the conductor tracks defined on the film and then bent over, where they are again pushed through the track.
- the contact surfaces are here essentially only through the penetration points the tips formed by the track.
- the slide Trace is very thin (usually in the range between 20 and 50 microns), this leads to an insufficient fixing of the foil conductor in the crimp part and to high contact resistance.
- the crimped part is intended to be bent in such a way Be sure that the free end of a crimp piece's top is just above the one To strip conductor track lying insulating layer and contacting the conductor should clamp against the bottom of the crimp.
- the bending process of Therefore Crimp presses must be extremely accurate with the smallest tolerances which is extremely problematic in practice and therefore not one can lead to reliable crimp contact.
- An electrical connector for connecting a foil to a wire conductor further known from DE-OS 1 957 183.
- the connector has two through one Folding line on separate flank parts. From the one flank part is a tongue punched free and U-shaped bent. In this U-shaped tongue is the wire conductor inserted. Between the tongue and the other edge part of the film conductor inserted and subsequently the connector for making the contact pressed together.
- the wire conductor and the foil conductor are here in the compressed Condition of the connector not at each other and a gas-tight Contact of the foil conductor can not be formed by such a connector become.
- From US-PS 3,715,457 is further a two-piece connector for a ribbon conductor known.
- the conductors are each relatively loose between two Layers of an insulating material.
- the connector has a lance-like Part on, from the front end of the ribbon conductor between the upper insulating cover layer and the conductor is inserted, so that this lance-like Part flat on the ladder rests.
- the cheeks of a U-shaped Crimp are from the back of the ribbon conductor forth through the insulating Layered next to the conductor, so that the conductor and the Ianzenartige Part of the connector as well as the insulating layers between these cheeks to come to rest. As a result, the cheeks are pressed inwards, Puncture the upper insulating layer and pierce the lanceous part be pressed. A gas-tight connection is thereby not achieved.
- From US-A-5 611 709 is a contacting of a flexible foil conductor with a cable by means of insulation displacement technology known.
- This insulation displacement technology the electrically insulating outer shell of the cable is cut through and contacted the head of the cable.
- the insulation displacement contact part has get a thigh, which carries the cutting parts as well as protruding cheeks, which hold the entire cable to the flexible foil conductor. It deals This is not a crimp contact.
- the object of the invention is to provide a crimp contact of a flexible foil conductor, which is easy to manufacture and reliable in its manufacture sufficient tolerances and allows the gas-tight. According to the invention succeeds this by a crimp contact with the features of claim 1.
- the crimp contact is thus made by placing next to the one or more to be contacted Foil (s) also a deformable pressure part is inserted into the crimping part and then the Crimpteil is pressed.
- Foil s
- Crimpteil is pressed.
- Due to the gas tightness of the Crimp contacts get neither liquids nor noxious gases (such as sulfur gases) in the contact, which otherwise leads to corrosion and thus to an impairment of the contact.
- EP 1 035 616 A1 which also has a crimp contact of a flexible Foil conductor shows.
- the projecting from a connecting web or leg Cheeks of Crimpteils are here but not directly opposite, but are offset from each other (seen in the longitudinal direction of the film conductor). Thus, no gas-tightness of the crimp contact is achieved.
- the mediated by the invention crimp contact electrical contact the film conductor can affect different parts: On the one hand, an electric Contact made between the trace and the deformable pressure part which in this case is a section of an electrical conductor, preferably a stranded wire or waveguide.
- the crimp part can do this be independent of the parts to be contacted, the itself also electrically can be insulating. Furthermore, the electrical contact between the Conductor and the crimp part be formed. Another alternative is that a contact between two arranged in the crimp, with your tracks against each other directed film conductors is produced. It can too several pairs of foil conductors to be contacted are arranged in the crimp part his.
- the mentioned contacting options can also be used with each other be combined. For example, the trace of a film conductor with the formed as a free end of a stranded wire deformable pressure member and with a Crimpteil be contacted, which on a pin of a plug part an electrical connector is formed.
- a crimp contact according to the invention are two interconnects 3, the on a film conductor 1 (only a part of which is shown in Fig. 1) applied are contacted with electrical conductors in the form of stranded wires 13.
- the foil conductor 1 has a film or carrier layer 2, on which the conductor tracks 3, for example, printed or applied by electroplating.
- Such foil conductor are under designations such as FLC (flexible layer circuit) or FPCB (flexible printed circuit board).
- FLC flexible layer circuit
- FPCB flexible printed circuit board
