Definitions
- the present invention relates to an electrical connector for a printed circuit board and other electrical line pieces, in particular for flexible printed circuit boards (so-called lextapes), and a connector system equipped therewith.
- Electrical connectors of the type mentioned are known in principle. Two such printed circuit boards can be connected to one another by means of these connectors. Such a connector can also be used to electrically connect a printed circuit board to pieces of electrical line, in order to connect the printed circuit board to electrical components, such as an operating device, for example, via the pieces of electrical line.
- a pull-off safety can be provided.
- this consists of clamping a printed circuit board section in the connector. Pinching can be facilitated by a ribbed clamping surface to improve trigger safety. Last but not least, the clamping force depends on the thickness of the printed circuit board and is therefore sometimes of fluctuating quality.
- the present invention relates to an electrical connector for a circuit board.
- this has a printed circuit board carrier for receiving a front-side contact section of the printed circuit board in a receiving direction.
- the electrical connector has a fastening element with coupling elements for form-fitting fastening of the printed circuit board—that is, the front-side contact section or via the front-side contact section—in the connector.
- the fastening element can be placed on the printed circuit board carrier in a placement direction such that the coupling elements fasten or connect the front-side contact section on both sides of the receiving direction—thus preferably at the edge of the printed circuit board.
- the possibility of fastening on both sides ensures a wide and thus favorable distribution of the holding forces, which in turn reduces the load on a printed circuit board to be fastened with the connector, particularly with regard to the fastening areas.
- a uniform distribution of the fastening areas can be achieved in this way, so that a uniformly acting strain relief is provided.
- the fastening sections can be provided at a distance from a central area of the printed circuit board, which is generally required for electrical contacting and is therefore kept freely accessible. This ensures an effective, safe and permanent electrical connection option for the printed circuit board.
- This attachment is preferably detachable - for example, by separating the fastener from the printed circuit board carrier by removing it counter to the placement direction - but it can also be made permanent.
- the printed circuit board carrier can preferably have a receiving section for receiving the end-side contact section.
- the printed circuit board can thus be securely accommodated in the connector and preferably also supported via its front-side contact section.
- the printed circuit board carrier and the fastening element delimit a receiving space for receiving the end-side contact section in the fitted state.
- the end contact portion can be securely received.
- an area of electrical contacting of the connector can be housed in this way, which in turn increases the safety of the connector and reduces risks for an operator.
- the receiving space can be sealed off from the outside at least when it is in place; preferably according to a defined degree of protection such as IP54 or IP64.
- a seal can be provided between the printed circuit board carrier on the one hand and the fastening element on the other hand, which seal becomes effective when the connector is placed and thus closed.
- the coupling elements can preferably be designed in such a way that they can cut through the end-face contact section on both sides of the receiving direction at the edges in the mounting direction in order to produce the form-fitting fastening. Since the severing occurs here at the edges in two spaced-apart areas, the holding force can be distributed accordingly and tearing of the printed circuit board can be reliably avoided or at least significantly reduced even in the event of shock and vibration.
- the aspect of severing also forms an independent aspect of the present invention, as described below.
- the coupling elements can preferably each have a cutting edge pointing in the mounting direction for severing the end contact section.
- a cutting edge enables a secure cutting contact due to its length.
- a cutting edge forms a comparatively large coupling surface in order to ensure secure attachment by absorbing any pull-off forces over a large area; This is particularly so in comparison to a small mandrel that breaks through the circuit board in the center.
- the coupling elements are preferably designed in such a way that they can deform the front-side contact section on coupling sections on both sides of the receiving direction at the edges in the mounting direction in order to produce the form-fitting fastening. Since the deformation occurs here at the edges in two spaced-apart areas, the holding force can be distributed accordingly. Overall, therefore, lower holding forces are required than in the case of a flat trapping or a punctiform deformation, while the security against being pulled off is increased.
- the aspect of deforming also forms an independent aspect of the present invention, as will be described below.
- the coupling elements can preferably each have a pressing edge pointing in the placement direction for deforming, preferably for plastic deformation, of the front-side contact section.
- a pressure edge due to its length, such a pressure edge enables a secure clamping contact.
- such a pressure edge forms a comparatively large coupling surface in order to ensure secure attachment over large areas to ensure absorption of any pull-off forces.
- such a pressure edge is comparatively simple in design and therefore easy to provide overall.
- the coupling elements can preferably be formed integrally with or as part of the fastening element. This preferably as cutting bars and / or clamping bars.
- the coupling elements or the cutting edges or the pressing edges or the cutting webs or the clamping webs can be designed as an integral injection molded part to form or with the fastening element.
- the coupling elements can be provided in a particularly simple manner. If material properties are required that cannot be met by the other material of the fastening element itself, the coupling element can also be provided separately and, for example, provided as an insert. It is conceivable, for example, to provide the coupling element as a stamped and bent part made from sheet metal. This applies equally to the deforming variant and the cutting variant.
- the respective coupling elements can preferably have a coupling surface pointing towards the placement direction.
- the coupling surface can preferably have the cutting edge and/or the pressing edge.
- the respective coupling elements preferably at least their coupling surface, can preferably be elongate and preferably extend transversely or perpendicularly to the pick-up direction and/or placement direction. Due to the elongate provision, a defined large coupling and thus secure form-fit fastening of the printed circuit board can be achieved. A holding force can thus also be reliably distributed on the printed circuit board or applied over a large area, which in turn relieves the printed circuit board in the event of pull-off forces, which in turn can reliably prevent damage to the same or the failure of the pull-off safety device.
- the coupling elements can preferably protrude towards one another on both sides of the receiving direction, preferably transversely or perpendicularly to the receiving direction and/or to the placement direction and/or, if present, into the receiving space.
- a secure and large-area form-fitting attachment can take place.
- a secure form-fitting fastening can always be ensured, even with fluctuating circuit board widths.
- the printed circuit board carrier preferably the receiving section, can preferably have one or one recess per coupling element, into which the coupling elements protrude in the mounted state. This preferably at least with their coupling surface. If present, the deformed coupling sections can also at least protrude into the recess(es) in the fitted state--alone or together with the coupling elements or coupling surfaces. On the one hand, a particularly secure form-fitting connection can be achieved in this way. For example, a safe cutting through of the printed circuit board is also achieved if, for example, the coupling elements have corresponding cutting edges.
- the coupling elements themselves protrude into the recess, they can also be preferably supported in the pick-up direction or in the opposite pull-off direction, which overall increases the stability of the form-fitting connection.
- the protrusion of the deformed coupling sections ensures a particularly stable form-fitting connection, for example when using the pressure edges or clamping webs.
- the form-fitting fastening is also independent of the thickness of the printed circuit board to be fastened or its end-face contact section.
- the respective recess can preferably extend in the placement direction, preferably into the receiving section or away from the receiving space. This ensures a particularly secure positive connection.
- the printed circuit board can be supported on the receiving section in order to enable reliable cutting or deformation.
- the coupling element can also be securely supported in the printed circuit board carrier—for example in or against the receiving direction.
- a recess provided in this way can easily be provided.
- the connector preferably the fastening element, can preferably have an electrical contact element in order to be in electrical contact with the received end-side contact section in the attached state. In this way, an electrical connection can be made particularly easily; for example simply by assembling the connector with the printed circuit board appropriately accommodated.
- the electrical contact element can preferably have a contact arm, preferably a spring contact, for electrical contact with the front contact section. This enables a particularly simple and safe electrical contacting of the connector to the circuit board; e.g. automatically when assembling the connector, i.e. when placing the fastening element on the circuit board carrier.
- the connector can preferably have several of the electrical contact elements, preferably in a row transverse to the receiving direction, in order to be in electrical contact with a different section (such as one of several electrical connection surfaces) of the front-side contact section in the mounted state.
- a plurality of electrical contact rows on the printed circuit board can be electrically connected or contacted, preferably independently of one another.
- the respective electrical contact element can preferably also have an electrical connection section for the electrical connection of an electrical line piece in order to electrically connect it to the printed circuit board.
- the electrical line piece can be a simple electrical connection cable, for example. It is also conceivable that the electrical line piece is a further (preferably elongate and/or flexible) printed circuit board with corresponding contact sections on the face side. The electrical connector can thus be used in a simple manner to connect the printed circuit board to any other electrical line piece.
- the electrical connection section can preferably have a further contact arm, preferably a further spring contact, for the electrical connection of the electrical line piece.
- a particularly simple, fast and secure electrical connection can be made possible by using a corresponding contact arm. For example, an electric cable can be cut to the desired length and connected on site as a piece of electric line, so that no unnecessary cable material is wasted.
- the printed circuit board carrier can preferably have guide sections on both sides of the receiving direction for the lateral guidance of the front contact section when it is received in the printed circuit board carrier. In this way, a secure and clear recording of the circuit board can be made possible.
- the printed circuit board carrier can preferably have stop sections for the frontal stop of the frontal contact section when being received in the printed circuit board carrier.
- the printed circuit board can be easily accommodated and the contact section on the end face can be positioned securely and precisely—for example with respect to the accommodation section.
- the fastening element and the printed circuit board carrier can preferably have corresponding connecting sections in order to mechanically connect them to one another.
- the form-fitting attachment can be permanently maintained in a simple manner.
- the mechanical connection can serve as feedback to the operator to confirm that the coupling elements have been positively secured to the printed circuit board.
- the connecting sections can preferably be designed in such a way that the fastening element and the printed circuit board carrier can be connected one after the other at different distances or gradations, as viewed in the mounting direction. For example, a first spaced position for selectively receiving the printed circuit board is conceivable here.
- the circuit board carrier and the fastening element are already connected in a captive manner and can, for example, be transported to a customer or the place of use.
- a printed circuit board can be directly accommodated with its end-face contact section for connection.
- a second fastening position for form-fitting fastening of the printed circuit board in the connector is then conceivable.
- the connector can immediately be moved easily and guided into the end position for form-fitting attachment by further bringing it together or plugging it together in the mounting direction. The operation of the connector is therefore particularly safe and easy.
- the connector can be provided in a captive manner, simply and immediately ready for operation.
- One of the fastening element and circuit board carrier preferably has a locking projection as a connecting section and the other of the fastening element and circuit board carrier has at least one locking recess as a connecting section.
- a latching connection forms a particularly simple, secure and intuitive mechanical connection option.
- a clicking noise can serve as feedback for the operator for a successful connection or fastening.
- one of the fastening element and circuit board carrier can have at least one latching projection as a connecting section and the other of the fastening element and circuit board carrier, preferably per side - e.g. with regard to the Recording direction or the placement direction on both sides - also have at least one corresponding locking recess as a connecting section.
- a plurality of snap-in projections can be offset from one another, seen in the mounting direction, in order to connect in succession to the same snap-in projection to cooperate.
- the above-described distances or gradations such as the first spaced position and the second fastening position—can be easily and securely set and permanently maintained as desired.
- the printed circuit board carrier and/or the fastening element are preferably produced at least partially or entirely from plastic and particularly preferably as an injection molded part. These parts are therefore particularly easy and inexpensive to produce.
- the printed circuit board can preferably be an elongated and/or flexible printed circuit board.
- the connector can thus be used in a particularly diverse manner.
- the printed circuit board carrier can preferably also be used to accommodate at least one additional end-side contact section of an additional (preferably elongate and/or flexible) printed circuit board in an additional accommodation direction.
- the fastening element can then be placed on the printed circuit board carrier in a placement direction in such a way that the coupling elements also fasten the further end-side contact section on both sides of the further receiving direction in a form-fitting manner in the same way.
- the connector can also be used as a similar connection between two printed circuit boards.
- the present invention also relates to an electrical connector for a printed circuit board.
- This has a printed circuit board carrier for accommodating a face-side contact section of the printed circuit board in a receiving direction, and a fastening element with coupling elements for form-fitting fastening of the face-side contact section in the connector.
- the fastening element can be placed on the printed circuit board carrier in a placement direction in such a way that the coupling elements cut through the end-face contact section on both sides of the receiving direction at the edge in the placement direction in order to produce a form-fitting fastening.
- the present invention also relates to an electrical connector for a printed circuit board.
- This has a printed circuit board carrier for accommodating a face-side contact section of the printed circuit board in a receiving direction, and a fastening element with coupling elements for form-fitting fastening of the face-side contact section in the connector. That Fastening element can be placed on the printed circuit board carrier in a placement direction in such a way that the coupling elements deform the front contact section on both sides of the receiving direction at the edges in the placement direction in order to produce a form-fitting attachment. All of the features and benefits previously described apply equally to this electrical connector.
- the present invention relates to a connector system which has a connector according to the present invention and a printed circuit board, preferably a flexible printed circuit board, with a front contact section.
- the front contact section is received in the circuit board carrier in the receiving direction.
- the fastening element of the connector is placed on the printed circuit board carrier in such a way that the end-face contact section is fastened in a form-fitting manner on both sides of the receiving direction by means of the coupling elements; this preferably by the above-described edge deformation or severing in the placement direction.
- the front contact section can preferably be in electrical contact with the electrical contact element, preferably its contact arm.
- An electrical connection is thus produced in a particularly simple manner; e.g. simply by directly assembling the connector with the received circuit board. This is all the easier if an electrical contact is provided by a corresponding contact arm.
- the connector system can preferably also have an electrical line piece, such as an electrical cable or another (preferably elongate and/or flexible) printed circuit board with a further front-side contact section, which is preferably connected electrically to the electrical connection section of the electrical contact element, preferably its further contact arm Circuit board is connected or connectable.
- the connector system can thus be used in a particularly simple manner to connect the printed circuit board to a further piece of electrical line.

- This coupling surface 40 can have the above-described cutting edge 41 and/or the pressing edge 42 .
- the respective coupling elements 4, preferably at least their coupling surface 40, can preferably be elongate and preferably transverse or vertical extend to the pick-up direction A and/or placement direction S. This can be seen in particular from FIGS. 5, 6, 8, 9, 11 and 12, according to which the coupling surface 40 extends perpendicularly to the receiving direction A and the placing direction S, respectively.
- the coupling elements 4 can project towards one another on both sides of the receiving direction A, preferably transversely or perpendicularly to the receiving direction A and/or to the placement direction S and/or, if present, into the receiving space 5, as shown in FIGS. 2, 5, 6, 7, for example , 9, 11 and 12.

- the cutting edge 41 protrudes into the recess 23 in the form of the insertion bevel.
- the clamping edge 42 projects into the recess 23 here.
- in the fitted state at least the deformed coupling sections 12 protrude into the recess(es) 23 in order to bring about the form-fitting attachment.
- the deformation of the coupling sections 12 preferably takes place in such a way that, as shown in FIGS. 8 and 12, the respective clamping edge 42 also protrudes into the recess 23, which ensures an overall particularly secure form-fit fastening.
- 12 and 13 show the circuit board 10 after the plastic deformation here with correspondingly deformed coupling sections 12.
- the respective recess 23 can, as shown for example in FIGS. 1, 8, 9, 11 and 12, preferably extend in the placement direction S. As shown in the exemplary embodiments, this is particularly preferably into the above-described receiving section 20 or away from the receiving space 5 .
- the fastening element 3 and the printed circuit board carrier 2 preferably have corresponding connecting sections 6, 7 in order to mechanically connect them to one another and secure them in this way, as can be seen, for example, in FIGS. 1 and 3 to 6 and FIGS. 9 to 12.

- the cover section 71 can also have a corresponding recess 70 here, for example.
- the latching recesses 7 are offset from one another in such a way that they each work together one after the other in a connecting manner with the same latching projection 6 .
- the fastening element 3 can first be placed on the circuit board carrier 2 in such a way that, as shown in FIGS Sides wall 30 provided recess 70 engages to secure the fastener 3 and the circuit board support 2 against each other, while still receiving the end-side contact portion 11 in the circuit board support 2 and its receiving space 5 is made possible.
- a latching projection 6 is provided on each side--here on the right and left with respect to the receiving direction A and the mounting direction S--which here, for example, extends parallel to the receiving direction A along the entire printed circuit board carrier 2.

- the spaced position can, for example, represent a delivery state of the connector 1, so that the connector 1 is immediately and easily ready for use.
- the locking projection 6 By moving the fastening element 3 further onto the printed circuit board carrier 2 in the placement direction S, the locking projection 6 then moves out of the recess 70 (e.g. supported by a run-on bevel 60 of the locking projection 6) and comes into locking engagement with the second locking recess here (here e.g. the cover section 71 the bottom wall 31 or recess 70 provided therein) in the fastening position in which the coupling elements 4 are in position for the above-described form-fitting fastening of a front-side contact section 11 of a printed circuit board 10 accommodated in the printed circuit board carrier 2 .
- the fastening position can be reached intuitively.
- the latching function can give the operator feedback that the fastening position has been reached.
- the division of the locking projections 6 according to FIG. 5 has the advantage that the parts 2, 3 can be moved relatively easily from the spaced position to the fastening position, where both locking projections 6 on each side then act, which then results in a particularly stable and durable operating condition.
