Definitions
- the present invention relates to a flex foil contact arrangement according to the preamble of the independent claim.
- Flex films are thin plastic films on which one or several metallic conductor tracks are attached. These flex films are characterized by their light weight and due to of the thin material due to its flexibility. With accordingly The foils are not only a wide conductor track layout for data signal transmission, but also for energy supply Can be used by consumers such as LEDs etc. It is also already known, contact arrangements at the ends of the flex foils to be provided on which the flex film is contacted.
- the object of the present invention is to create something new to provide for commercial use.
- a plurality provided by contact elements in particular in a common Bracket are housed.
- This bracket can in turn in turn have a conductor track fixing area.
- the holder can be in a particularly preferred Variant have a lid that can be folded over the extension arm.
- the hinged lid can be designed to Fix the conductor track and / or the cantilever arm to the support area. So the contact point can on the one hand against mechanical Damage caused by foreign bodies is particularly effective from the outside protected and on the other hand against a contact fault can be prevented by moving flexible foils.
- the bracket can have openings for inserting the rear Have contact pins, it being particularly preferred that if the contact pin receiving chamber has four walls and in particular has a generally square cross section, on at least two opposite walls of the contact pin receiving chamber Contact pin centering springs arranged are. These can be behind a rear insertion funnel in the contact pin receiving chamber by driving in a tab be educated. This way is a clean and vibration-proof Centering the pins in the contact pin chamber ensures what operational safety in particular elevated. It is particularly preferred if there is also a third spring tongue inside the contact pin receiving chamber on the Contact pin comes into contact because that is the vibration resistance further increased.
- the cantilever arm is in a preferred embodiment not straight, but curved. This allows one stronger absorption of movements between flex film and Contact arrangement or of the contact element and connector pin.
- the Cantilever arm can in particular be designed to be resilient.
- the cantilever arm is one for fixed Connection with the conductor track formed contact area having.
- the firm connection can be done by soldering the Contact area done on the trace or using a roughened contact surface which is formed by their roughening penetrates the conductor insulation and / or digs into the conductor track.
- This roughening is particularly preferred and advantageous because it is a good and All-over contacting in the contact area enables.
- To the roughening can have a profile or height of at least Own 0.1mm. It is particularly advantageous that and if the contact surface is arranged at the end of the cantilever arm. This enables the roughening to be relative to the contact Flex film moves and so well through the insulation digs.
- the support area on the cantilever arm at least one tooth tip for insertion into the flex film is provided.
- the piercing prevents the Flex film can be pulled out easily, and on the other hand, that it slips sideways, leading to reverse polarity certain lines can lead against each other. A bend this tooth is not required. Rather, even without Crimping or the like achieved an improved fixation.
- the tooth tip is typically and preferably at least in penetrate the flex film base film and at least deform it, but preferably pierce.
- the tooth tip is typically in one piece with the metal sheet arm punched out and bent over.
- tooth tip It is preferred to close the tooth tip from the support area so far that they are in a flex foil area free of a conductor track punctures. This prevents the trace from being destroyed will and deviations from the electrical setpoints occur. In addition, there is a risk of a separation of positions, i.e. one Separation of base film and conductor track prevented. To do that Ensure insertion into a flex foil area free of a conductor track To be able to, it is particularly preferred if the tooth tip sideways at a suitable distance next to the support area is arranged.
- the support area can be at a point of closest approximation of the cantilevered extension arm to the flexible film provided his; in such a case it is particularly preferred if the tooth tip is provided distally from the support area, that is further away from the contact pin receiving chamber. This causes, that the contact area first comes into contact with the flex film is pressed, then one if necessary at the support area intended roughening through the flexible foil insulation over the Dig through or rub through the conductor track and only after Insertion of this process fixates the tooth tip in the Flex film is pressed in.
- tooth tip generally sword-shaped, with a parallel to the cantilever arm or to the conductor track of greater width than transverse to the cantilever arm or to the conductor track. This results in a fixing elongated hole at the puncture, that for damage-free force absorption against displacement is particularly suitable.
- the cantilever arm is resilient is designed.
- the tooth tip has preferably a length that is also with resilient yielding Cantilever arm lowering the lower end of the tooth tip below the flex film guaranteed.
- the resilient design of the cantilever arm a stronger movement absorption between flex film and contact arrangement or from Contact end and connector pin.
- the tooth tip can be used in particular for piercing or piercing be formed a conductor-free flexible film area. So are the forces acting on the tooth tip are lower, which is advantageous during assembly and with the same material thickness too leads to lower error rates.
- the tooth tip can do this immediately to the side next to the area of the electrical contact be formed between the flex film and the contact element. This ensures that the fixation effect is particularly positive on the electrical properties of the flex foil contact arrangement effect. Electrical contacting by means of according to the invention, the tooth is not absolutely necessary, albeit possible in principle.
- the tooth is formed with a positive locking means to a positive Intervention of the tooth penetrated by the flexible film to be provided at the support area.
- This preferred training, in which a positive engagement is achieved is particularly advantageous because by the positive locking a loosening of the tooth and / or a movement the same, in particular only a slight back and forth movement can be prevented, which would otherwise have a negative impact on the Long-term stability of the flex film affects. It is preferred if the flex foil contact arrangement is designed such that the Tooth tip is formed to push through the flexible film automatically is. Otherwise, e.g. the film is pre-punched, but which is usually an additional step is rather undesirable.
- a recess can be provided in the support area, through which the tooth can bump. This ensures that the Tooth just has to push through the thin flex film and then in and / or can form-fit with the recess.
- the tooth can have a notch on the contact area can be locked.
- the form fit is Locking achieved.
- the support area is in a particularly preferred variant and the tooth is provided on a respective extension arm, which each has a curvature towards the flex film, wherein the tooth tip is provided distal from the support area.
- connection can be used for repairs or the like. Receive a particularly secure connection because it is ensured that in the actual flex foil contact area no excessive stress occurs. This allows even if the connection, as preferred, is designed to be able to conduct high currents over the contacts.
- the relief arrangement can be formed by a loop bow, which is implemented in particular by a cam, in particular a cam which hangs from a cam cover which can preferably be folded down, in particular pivotally attached to a film hinge, which cam can be up to and preferably in one Recess enters the housing bottom and around which the conductor track film can be pulled.
- the conductor track film experiences frictional restraint.
- retaining sheets are provided which pass through corresponding openings in the conductor track film and thus hold it back in a form-fitting manner.
- the retaining leaves can in turn be provided on the housing cover, which in turn can preferably be arranged in a foldable manner, in particular on a film hinge.
- the strain relief is both for the transition from trace foils to consumers or other plugs as well for that Connection of conductor foils can be used together.
