Description

Technical Field

[0001] The present invention relates to a connection and electronic module as described in the preamble of claim 1. Background Technology

[0002] Regarding prior art, refer to DE102011051154A1. This document discloses a bus-connected, tandemly arranged connection and electronic module for controlling and / or monitoring technical processes and / or for industrial and / or building automation. The connection and electronic module has a disc-shaped and / or block-shaped structure and is designed to form a connection system with other connection and electronic modules. The connection and electronic module has at least the following features: at least one base terminal bracket for fixing to a mounting base; at least one electronic device housing mountable to the base terminal bracket, the electronic device housing having at least one circuit board with electronic circuitry; one or more bus conductor contacts for further conducting at least one energy and / or data bus along the tandem arrangement direction to adjacent, tandemly arranged connection and electronic modules; and a connection unit pivotally fixed to the base terminal bracket, the connection unit having, on one hand, a connection plane with a connector for connecting external conductors and on the other hand, a circuit board edge connector with contact sleeves for connecting to conductive contacts in the edge region of the circuit board.

[0003] These connections and electronic modules have proven to be reliable, but relatively high wear may occur on the edges of the circuit board, which are made of a material with a relatively high glass fiber content and which is relatively prone to wear, and also on the contact sleeve when repeatedly contacting and releasing the circuit board edge connectors. Measures are needed to reduce this wear.

[0004] To prevent excessive wear on the edges of circuit boards and the conductive contacts located therein, US 9,893,441B2 proposes: at least covering the edges with conductive contacts with a protective strip, which widens the connecting contact sleeve before contacting the circuit board, thus resisting excessive wear on the circuit board edges and the connecting contact sleeve. Further improvements to this technical solution are possible. Summary of the Invention

[0005] Based on the prior art, the objective of this invention is to implement, in a module of the type said, protection of the edges of the circuit board and the contact areas therein in a structurally simple manner, as well as protection of the contacts of the circuit board edge connectors as much as possible against excessive wear during repeated contact.

[0006] The present invention solves the aforementioned task through the technical solution of claim 1.

[0007] Advantageous constructions of the present invention are derived from the dependent claims.

[0008] According to claim 1, the following technical solution is proposed: a connection and electronic module, particularly a connection and electronic module capable of being arranged in series, the connection and electronic module having a disc-shaped and / or block-shaped structure, the connection and electronic module having at least the following features: an electronic device housing open at least on the connection side, a circuit board housed in the electronic device housing, the circuit board having at least one row of circuit board edge contacts on the circuit board edge pointing towards the connection side; and at least one connection unit movable relative to the electronic device housing along and against the contact direction, the connection unit having a contact sleeve on the contact side corresponding to the circuit board edge contacts, the contact sleeve for contacting the circuit board edge contacts, the edge of the circuit board having the circuit board edge contacts being provided with a wear-resistant protective strip, the wear-resistant protective strip being connected upstream of the circuit board edge along the contact direction, the wear-resistant protective strip being integrally constructed with the electronic device housing. In this way, good protection is provided for the circuit board edge when the circuit board contact area contacts the connection unit in a particularly simple manner, the protective strip being reliably and firmly constructed on the electronic device housing. This eliminates the need for costly pre-processing of the circuit board edges using milling tools, which are used to construct the circuit board edges into a tapered shape.

[0009] Furthermore, the process of building (raw) circuit boards is kept in a standard process, thereby minimizing costs and process run time.

[0010] Here, according to a preferred construction, it can be advantageously specified that the wear-resistant protective strip is integrally connected to the remaining portion of the electronic device housing via one or more connecting tabs. This construction allows for particularly simple manufacturing and ensures a particularly good fit between the protective strip and the rest of the device.

[0011] Here, it is suitable and preferred that the protective strip extends transversely to the circuit board over its entire width, or that the width of the protective strip is greater than the width of the circuit board transversely to its main extending plane, such that the contact sleeve is sufficiently widened when placed on the circuit board so that it does not need to contact the actual edge of the circuit board.

[0012] Furthermore, according to another preferred construction, the protective strip can be suitably specified to taper away from the edge of the circuit board, thereby ensuring a uniform and easy widening of the contact sleeve when the circuit board is touched.

[0013] Another preferred configuration may specify that the contact sleeve has contact legs that are slightly convex on their opposing, inner sides facing the circuit board, such that the contact sleeve contacts the contact area substantially in a point shape or in a line shape in the region of the contact portion closest to the contact area of ​​the circuit board on the convex inner side of the contact legs.

[0014] Here, the wear-resistant protective strip can extend parallel to the edge of the circuit board.

[0015] Then, it can be further advantageously specified (and this is an advantageous improvement of claim 1 and its referenced dependent claims, but also another advantageous invention in combination with the preamble of claim 1 and optionally with any of the other dependent claims): the protective strip has a row of recesses in the area in which the contact sleeve sweeps across the protective strip when the connecting unit is placed on and removed from the electronic device housing, the recesses being constructed on the edge of the protective strip corresponding to the contact area and the contact sleeve, such that the contact sleeve, when sweeping across the protective strip, does not contact the protective strip with a corresponding contact portion, but rather at one or more theoretical friction portions laterally arranged relative to the contact portion. This provides very good protection for the contact sleeve, particularly in the area of ​​the actual contact portion, against wear caused by establishing or disengaging the contact.

[0016] This construction scheme can be advantageously and optionally improved by the following manner: the width of the protective strip perpendicular to the circuit board, even in the region of the deepest part of the recess, is at least exactly equal to or greater than the width of the circuit board.

[0017] Then, the wear-resistant protective strip can extend parallel to the edge of the circuit board, and the wear-resistant protective strip can be form-locked onto the housing, particularly form-locked onto the housing against the contact direction.

[0018] According to another preferred embodiment, it may also be suitably specified that the protective strip is made of the same insulating plastic material as the electronic device housing and is manufactured together with the electronic device housing in a plastic injection molding process, wherein the insulating plastic material is preferably harder than the material of the circuit board.

[0019] This invention is applicable to both configurations in which the connecting unit is pivotally mounted relative to the electronic device housing and configurations in which the connecting unit is movably mounted relative to the electronic device housing.

[0020] Before describing the preferred embodiments, it should be noted that while some preferred configurations are also described in detail below, the invention is not limited to these configurations and can be modified in any way within the scope of the claims. Concepts such as "upper," "lower," "front," or "rear" should not be construed as limiting, but only relate to the corresponding arrangement shown. Furthermore, when interpreting individual components, these components can be conceived in principle with various configurations unless otherwise explained. In addition, kinematically opposite arrangements of the shown configurations also fall within the scope of protection. Attached Figure Description

[0029] The invention is illustrated below with reference to exemplary connection and electronic modules that can be used to control and / or monitor technical processes and / or for industrial and / or building automation. The concept of the connection and electronic module should be understood as enabling wires to be connected to a circuit board. The type of electronic circuitry on this circuit board is not important within the scope of this invention. The circuit board may, for example, have signal processing electronics or, however, simply have printed wires connected to bus contacts, etc.

[0030] Therefore, a connection module can be provided that is solely for connecting to external devices via wires or plugs. Typically, this module serves both as a connection to external devices or their wires, and in other cases, particularly as an electronic function (e.g., signal processing).

[0031] Here, the connection and functional modules can be perpendicular to Figure 1a The direction of the series arrangement of the plane in the figure (also see) Figure 1b and Figure 1c The electronic modules are arranged in series, and the connections and functional modules may optionally form a bus that can be connected directly or, for example, via a gateway to a higher-level control device. However, the invention is also applicable to electronic modules that do not form such a bus.

[0032] Figure 1aA side view of an exemplary electrical connection and electronic module 1 is shown. This module can be mounted (particularly snapped) onto a mounting base, such as a support rail T extending in the Y direction, and can be arranged in series with other modules on the mounting base. For example, this connection and electronic module can be used as part of a control system for automation technology. An application-specific combination of a gateway and such a connection and electronic module 1 enables the monitoring and / or control of external electrical devices (field devices, starters, actuators, etc.) that can be connected to the connection and electronic module 1 of the connection system according to the invention.

[0033] The connection and functional module 1 shown in Figures 1 and 2 has a base terminal bracket 2, which is equipped with fixing devices, including locking devices 3 and 4, for snapping onto a support rail (not shown here).

[0034] However, the present invention is not limited to such a construction scheme. The present invention is also applicable to the interconnecting and electronic modules 1 that can be arranged in series, said modules being mounted on a mounting base different from the support rail, such as a wall.

[0035] An electronic device housing 5 is placed or can be placed on the basic terminal bracket 2. Figure 1a The electronic device housing has at least one or more circuit boards 6 ( Figure 1b and Figure 1c or Figure 3b The circuit board may also be equipped with electrical contacts, particularly circuit board edge contacts 61 (hereinafter also referred to as contact area 61) and structural elements. Circuit board edge contacts 61 are understood to be contacts located in the edge area, for example, in the form of contact surfaces, which can make contact with circuit board edge connectors. Circuit board edge contacts 61 may, but need not, precisely reach the corresponding edge of the circuit board 6.

[0036] Within the scope of this invention, the basic terminal bracket 2 and the electronic device housing 5 can also be combined into a single-piece or multi-piece unit (not shown).

[0037] The circuit board 6 has two main sides 62, 63 extending here along the Y and Z directions, which are exemplarily oriented perpendicular to the series arrangement direction, which is advantageous but not mandatory. The circuit board 6 also has a surrounding circuit board edge 64. The electronic device housing 5 has a spreading upper side. On this upper side, the circuit board edge 64, together with the circuit board edge contacts 61, is accessible, such that the circuit board edge contacts 61 are accessible and contactable. In the embodiment shown in the figures, the circuit board edge contacts 61 are arranged in a row sequentially along the upper circuit board edge 64 in the Z direction. Here, the circuit board edge contacts may be arranged sequentially along the Y direction on one main surface 62, 63 of the circuit board, or particularly also oppositely on both main surfaces 62, 63, near this circuit board edge 64.

[0038] A connection unit 7 is mounted on the base terminal bracket 2 and the electronic device housing 5. This connection unit has a connection housing 71, in which multiple wire connectors 72 arranged in a row are constructed for connecting external wires or plugs, etc.

[0039] These wire connectors 72 can be configured in various connection technologies, such as tension spring connectors, IDC connectors, or threaded connectors. This list is not exhaustive. Other connection technologies, such as plug connectors, can also be implemented. These wire connectors 72 are preferably (but not mandatory) configured as push-in connectors (see... Figure 5 The connector is a tool-free device that allows for connection by inserting a wire into the clamping area of ​​the connector. In the connected state, the clamping legs of the push-in connector clamp the wire within the clamping cage onto the busbar. Figure 5 ).

[0040] The connecting unit 7 also has a circuit board edge contact sleeve 73 (also referred to as contact sleeve 73 in the application). The contact sleeve 73 is designed to bridge one of the edges 64 of the circuit board 6, or to accommodate the circuit board edge 64 between its two contact legs 731 and 732, which then respectively contact at least one of the circuit board edge contacts 61.

[0041] The wire connector 71 and the contact sleeve 73 can be electrically connected to each other as a single piece and constructed as metal components. However, the wire connector and the contact sleeve can also be constructed as multiple pieces and connected only indirectly, for example, via electrical or electronic structural components (not shown).

[0042] The electronic device housing 5 and the connecting unit 7, or the base terminal bracket 2 and the connecting unit 7, can be pivotally connected in the joint region, allowing the connecting unit 7 to pivot to open positions with different widths and opening angles α (see...). Figure 1a , Figure 2a , Figure 3a , Figure 4a And it can pivot to a closed position (see) Figure 2a It is also conceivable that the connecting unit 7 can be movably disposed relative to the electronic device housing 5 (e.g., in...). Figure 1a The device can move downwards and backwards (not shown) on the corresponding sliding guide of the base terminal bracket 2. The connecting unit 7 and its connecting housing 71 are used to close the electronic device housing 5 upwards, in the closed position (see...). Figure 2a The contact sleeve 73 contacts the edge contact 61 of the circuit board.

[0043] The basic terminal bracket 2, the electronic device housing, and the connection unit 7 can all have a substantially disc-shaped structure and be perpendicular to... Figure 1a The planes can be connected in series and preferably can be mechanically and electrically coupled.

[0044] The electronic device housing 5 has a geometry adapted to the geometry of the base terminal bracket 2. The circuit board 6 may optionally contact the contacts of the base terminal bracket 2 (not shown here) when mounted on the base terminal bracket 2.

[0045] With the chosen construction method, the connection unit 7 can be pre-wired and can be simply opened and then closed when the electronic unit or electronic device housing 5 must be assembled or replaced using the circuit board 6.

[0046] To protect the circuit board edge 64 and the circuit board edge contact 61, and preferably the circuit board edge contact sleeve 73, from wear during contact and release, it is stipulated that: adjacent to the circuit board edge 64 (on which the circuit board edge contact 61 is constructed, exemplarily described here along the Z direction), the circuit board edge 64 is provided with a wear-resistant protective strip 51, which is along the contact direction ( Figure 1a The arrow P in the diagram, or rather, along the pivot direction (arrow P), is also connected upstream of the edge 64 of the circuit board.

[0047] This wear-resistant protective strip 51 (hereinafter also referred to as the protective strip) is preferably constructed as a single piece with the electronic device housing 5. This means that the protective strip 51 can be injection molded onto the electronic device housing 5 in one piece. The protective strip can be used, for example, via one or more connecting joints 53 (see also...). Figure 4aIt is integrally connected to the remaining part of the electronic device housing. This type of manufacturing is functionally reliable, simple, and inexpensive.

[0048] Figure 4 also illustrates another alternative type of securing the protective strip 51. Alternatively, the protective strip may be additionally or alternatively secured to the housing 5 in a form-locking manner. Here, this is done by means of a pin 54, which presses the protective strip into its recess 55 from above. The pin 54 may be provided on a lever element for releasing the electronic device housing and / or circuit board 6.

[0049] The protective strip 51 is preferably made of the same insulating plastic material as the electronic device housing 5 and is manufactured together with the electronic device housing in a plastic injection molding process. This insulating plastic material is different from the material constituting the circuit board 6, in particular a harder material, and in particular does not contain glass fiber or has a much lower glass fiber content compared to the material of the circuit board 6.

[0050] exist Figure 1c The diagram depicts a cross-sectional view of the protective strip 51. The protective strip 51 is preferably constructed such that it extends transversely to the circuit board 6 (here along the Z direction) over the entire width or substantially the entire width of the circuit board edge 64. Particularly preferably, the protective strip 51 is slightly wider than the circuit board 6 on its side facing the circuit board 6, perpendicular to the circuit board 6. The protective strip 51 can taper from the circuit board edge 64 along the Z direction. The protective strip also extends strip-shaped parallel to the circuit board edge 64 along this edge.

[0051] In this configuration, the protective strip 51 is not connected to the circuit board 6, but rests against it. Upon contact, the circuit board edge contact 61 presses the protective strip 51 against the edge of the circuit board edge 64. During retraction, the connecting tab 53 prevents the protective strip 51 from lifting off the circuit board edge 64, thereby protecting the protective strip 51 from deformation and damage. If one of the circuit board edge contact sleeves 73 (when the connecting unit 7 pivots towards the electronic device housing 5 towards the circuit board edge 6) reaches the protective strip 51, this contact sleeve 73 is widened as it passes the protective strip during further pivoting of the connecting unit 7, and this widened contact sleeve reaches the circuit board edge contact 61, without actually widening the contact sleeve 741 of the circuit board edge 64. Thus, the protective strip 51 serves to reduce wear on the circuit board edge 64. This protective strip also does not need to have a tapered profile on the edge itself to ensure that the widened contact sleeve 73 itself is constructed during subsequent processing of the circuit board edge.

[0052] Preferably, the contact sleeve 73 is on the inner side of its contact legs 731, 732 facing the circuit board 6 (see for details). Figure 7The simplified diagram is slightly convex, such that the contact sleeve 73 contacts the contact area 61 only in a point or line shape at the contact portion 7311 closest to the circuit board 6 on the convex inner surface 62 of the contact area 61. In this case, to optimize wear protection, it can be specified that the protective strip 51 has a row of recesses 52 in the area where the contact sleeve sweeps across the protective strip when the connecting unit 7 is pivoted onto and from the electronic device housing 5, the recesses being constructed on the edges of the protective strip 51 along the X and Z directions corresponding to the contact area 61 and the contact sleeve 71 (see [reference]). Figure 3a , Figure 4a , Figure 7 ).

[0053] These recesses 52 are configured and sized such that when the contact sleeve 73 passes over the protective strip 51, it does not contact the protective strip 51 with the contact portion 7311, but rather passes over the recesses 52 of the protective strip 51 at at least one or both of the theoretical friction portions 7312, 7312 that are laterally arranged relative to the contact portion, without the contact portion contacting the protective strip 51.

[0054] It is particularly preferred that the width of the protective strip 51, even in the region of the deepest part of the recess 52 (which is perpendicular to the circuit board 6), is exactly equal to or greater than the width of the circuit board 6.

[0055] In this way, a significantly improved protection for the contact sleeve 73 is achieved in a structurally simple manner when the contact area 61 of the circuit board is touched and when the contact sleeve 73 is released from the contact area of ​​the circuit board, because the actual contact portion 7311 of the contact sleeve 73 is not worn to a certain extent during these processes.

[0056] The protective strip 51 can be provided at either the pivotable connecting unit 7 on the electronic device housing 5 or at the connecting unit 7 that can be moved and guided when the connecting strip is placed on and removed from the electronic device housing 5 (the latter is not shown). Furthermore, the protective strip 51 can be implemented at either the connecting unit 7 provided on the base terminal bracket 2 or at the connecting unit 7 that is directly pivotally or movable on the electronic device housing 5 (the latter is not shown).

[0057] Unlike the previous version, the connecting unit can be moved not only to the upper edge of the circuit board, but also to the lateral edge of the circuit board to enable contact thereon. Within the opposite kinematic range of the invention, it is also conceivable, for example, that the connecting unit is stationary and, for example, constructed on the base terminal support, and that, for contact, the electronic device housing having the circuit board is placed on this connecting unit within a range of relative movement.
