Description

Technical Field

[0001] The present invention relates to a system for electrically connecting two controller system modules (eg, automation controller system modules) which are mounted side by side on a rail for holding the controller system modules.

[0002] Furthermore, the present invention relates to a corresponding method. Background Art

[0003] US 10186821 B2 describes a modular bus system comprising individual input / output function modules which are arranged side by side in the direction along a support rail.

[0004] An automation controller system typically includes several individual controller system modules that are mounted together on a rail, for example, on a wall or in a controller cabinet. The rail is, for example, a standardized equipment rail. Typically, the rail is attached to extend in a horizontal manner, and several controller system modules are arranged close to each other on the rail. As an example, such rails are defined in DIN EN 60715. Typically, each controller system module includes a mounting fixture that is used to mount the individual controller system modules on the rail. In addition, a plurality of rails can be arranged in a plurality of rows spaced vertically apart from each other.

[0005] According to one aspect, the rail may have a flat shape. For example, the rail may be a profiled strip. The rail may have a (longitudinal) direction, which direction typically extends horizontally if the rail is installed. If the rail has a flat shape, it may also refer to the plane of the rail, which is the plane along which the flat shape extends. If reference is made to the (longitudinal) direction or plane of the rail, it may be considered that the module is installed to the rail as intended.

[0006] The modules may comprise, for example, cable terminals for connecting Ethernet cables, bus cables, other data cables, power cables and / or etc. Typically, components like actuators and / or sensors may be connected to at least some of the controller system modules.

[0007] Typically, controller system modules must be connected to allow data exchange between them, such as via a network cable or bus cable. This allows different controller system modules to work together as part of an automation controller system. Further, at least some of the controller system modules may have to be connected by power cables to provide power between them.

[0008] This becomes more difficult with the increasing complexity of automation controller systems. First, cables for connecting different controller system modules require space, but space in control cabinets is usually limited. Second, some control cabinets are ventilated, and additional cables may impair circulation. Third, with the increasing complexity of automation controller systems, it becomes more difficult and error-prone to properly distribute and connect individual cables to specific controller system modules. Correct installation and wiring become complicated and time-consuming. In addition, cables are costly. Finally, all cable terminals of controller system modules are usually located only on the upper and bottom surfaces of the controller system modules to allow a small installation depth (e.g., within a cabinet). Therefore, the space available for cable terminals on individual controller system modules is very limited. However, the cable terminals required to allow data transmission between controller system modules require a portion of this limited space. Therefore, connecting controller system modules to each other via cables reduces the available space for other cable connections (e.g., input / output ports (I / O ports) for sensors, actuators, etc.). Summary of the invention

[0009] The problem underlying the present invention is therefore to provide a system for connecting controller system modules which is cost-effective, space-saving and allows easy installation.

[0010] This problem is solved by a system for connecting two controller system modules according to claim 1. Preferred embodiments are described in the dependent claims.

[0011] The system comprises a connector having a connector housing, wherein a first module of the two controller system modules comprises a first mounting portion for receiving a first portion of the connector housing at an end portion of the first module facing a second module of the two controller system modules, wherein the second module comprises a second mounting portion for receiving a second portion of the connector housing at an end portion of the second module facing the first module,

[0012] wherein the system includes an engagement mechanism for releasably mechanically securing the connector to the first module and the second module when the first portion is received in the first mounting portion and the second portion is received in the second mounting portion, and

[0013] The system includes an electrical connection mechanism for electrically connecting the first module to the second module via the connector when the connector is inserted into the first mounting portion and the second mounting portion.

[0014] The controller system modules (hereinafter also referred to as "modules") are mounted on rails for holding the controller system modules. The controller system modules are mounted side by side on the rails, ie close to each other on the same rail.

[0015] The rail may be a standardized device mounting rail, for example according to DIN EN 60715 or the like.

[0016] The controller system module (module) may be an automation controller system module. The controller system module may be configured to form part of an automation controller system. In particular, the controller system module may be an automation controller system module of an automation controller system for controlling a climate system, parts of a climate system (including an air conditioning system and / or a refrigeration system), and / or an industrial facility (e.g., a production facility).

[0017] As an example, the controller system may be configured to control components such as actuators, compressors, valves, fans, robots, etc., such as components within an automation system. The modules may be configured accordingly.

[0018] According to one aspect, the term "controller system module" may encompass, for example, electronic controller modules, power supply modules, input output modules (I / O modules), and the like.

[0019] In one embodiment, at least one of the modules (e.g., at least one of the first module and the second module) can be connected to at least one sensor, for example, to a temperature sensor, a fluid flow sensor, a humidity sensor, and / or a dew point sensor. The controller system (particularly the first module and / or the second module) can be configured to provide control signals for controlling operating components (e.g., actuators, valves, fans, compressors, heat exchangers, fluid flow mixers, etc.) based on information received from the sensor(s). At least one of the first module and the second module and / or another module can be configured to be connected to such operating components.

[0020] A respective module may include one or more electrical and / or electronic components, such as a circuit board, a processor, a memory, a speaker, a power supply (eg, a battery), and the like.

[0021] According to one aspect, at least one of the first module and the second module may include a network connector as a cable terminal, such as an Ethernet connector and / or a bus connector.

[0022] Each of the two controller system modules mounted adjacent to each other on the rail comprises a mounting portion (for receiving a connector), wherein the first module comprises a first mounting portion and the second module comprises a second mounting portion. The first mounting portion and the second mounting portion are arranged on respective ends of the modules facing each other. In particular, the first mounting portion and the second mounting portion are arranged close to each other (when the modules are mounted side by side on the rail) so as to form a common receiving portion for the connector (respectively, a connector housing). The connector housing (and therefore the connector) can be placed in a detachable manner in the receiving portion formed by the first mounting portion (of the first module) and the second mounting portion (of the second module).

[0023] According to another aspect, the engagement mechanism can be configured to guide the connector housing to a predetermined final position. In more detail, at least one of the first mounting portion and the second mounting portion (preferably both) is configured to guide the connector housing to a predetermined final position. The connector housing may include geometric elements that correspond to the guide portions of the mounting portion. Such guide portions may include, for example, protrusions that interact with grooves of the connector housing and / or with other objects around. The engagement mechanism may include, for example, a protrusion and a pin hole mechanism. In one embodiment, the first mounting portion and the second mounting portion include at least one pin hole, which is used to receive corresponding protrusions (corresponding "lance protrusions") of the connector (in more detail, the connector housing).

[0024] Once installed, the connector housing is held in a detachable manner by the engagement mechanism so that the connector housing can be easily removed. This allows easy modification of the module layout and creates good flexibility.

[0025] In one embodiment, the engagement mechanism comprises a snap connection. A snap connection is a connection that is easy to assemble. The elements of the snap connection can be bent in a predetermined manner so that the element can snap into a recess or the like in an assembled state. When the element is transferred in its bent state, the engagement mechanism disengages and the connector housing can be removed. In one embodiment, the snap connection is configured so that it can be manipulated without tools.

[0026] In one embodiment, the snap connection comprises an elastic snap member, such as an elastic tongue, on the connector housing. Providing the elastic snap member on the connector housing makes the process of producing the snap connection easy. In particular, the snap member can be integrally formed with (a part of) the connector housing. Furthermore, in the event of failure of the elastic member, the connector housing can be easily and cost-effectively replaced.

[0027] In one embodiment, the first module and the second module include a catch feature for catching the catch member when the first portion is received in the first mounting portion and the second portion is received in the second mounting portion. For example, the catch feature can be formed as a hole or a recess. The catch feature can be placed so that when the connector housing is placed in a predetermined position in the receiving portion, the catch member of the connector housing can interact with the catch feature. This allows a detachable connection that is easy to install and remove.

[0028] In one embodiment, the first mounting portion and the second mounting portion are mirror-symmetrical to each other, wherein the connector housing has a corresponding mirror-symmetrical property with respect to a center plane. In particular, the first and second portions of the connector housing may be mirror-symmetrical about the center plane. The mirror-symmetrical property allows the first and second mounting portions to also be formed as mirror-symmetrical. In particular, the first and second mounting portions may be mirror-symmetrical to each other about an abutment plane, at which the first and second modules face each other and / or abut each other when the first and second modules are mounted side by side on the guide rail. The abutment plane may be (at least) substantially perpendicular to the guide rail.

[0029] In the mounted state of the connector housing in the receiving part, the center plane is arranged exactly between the first module and the second module. This allows for low production costs for the module housing and the connector housing. In particular, the system can be configured such that the center plane (of the connector housing) coincides with the abutment plane in the mounted state, i.e. when the connector housing (and therefore the connector) is in a predetermined final position.

[0030] The system (in particular at least one of the first mounting part and the second mounting part and the connector housing) can be configured to have a mechanical poka-yoke function, thereby ensuring that the connector can be mounted to the first module and the second module in only one single predetermined final position and spatial orientation. Thereby, it can be ensured that the electrical connection mechanism connects only predetermined contacts of the first module and the second module. This applies even if the contacts and / or the corresponding functions are arranged in an asymmetrical manner in the corresponding modules.

[0031] In one embodiment, at least one of the first mounting portion and the second mounting portion is asymmetric about a plane perpendicular to the abutment plane parallel to the longitudinal direction of the guide rail (when the first module and the second module are mounted on the guide rail), so that the connector can be inserted into at least one of the first mounting portion and the second mounting portion along the insertion direction in only one spatial orientation. Additionally or alternatively, a portion of the connector configured to be received in the receiving portion (especially a portion of the connector housing) is asymmetric about a plane perpendicular to the center plane and parallel to the insertion direction. The connector housing can be inserted into the receiving portion only in a specific alignment. Therefore, if the connector housing is inserted in the wrong way, the engagement mechanism will not work, so that the connector housing can only be installed in the correct way. In particular, at least one of the first mounting portion and the second mounting portion can be asymmetric about a plane (at least substantially) perpendicular to the abutment plane and / or perpendicular to the insertion direction.

[0032] The insertion direction may be parallel to the abutment plane. The insertion direction may be (at least substantially) perpendicular to the guide rail (if installed). The system may be configured such that the connector must be inserted along the insertion direction from the top side of the (adjacent) first and second modules towards the guide rail, wherein the top side faces away from the guide rail.

[0033] If the connector is installed between the first module and the second module (when the first module and the second module are arranged side by side on the rail), the electrical connection mechanism is suitable for (automatically) establishing a data connection and / or a power connection between the first module and the second module. In other words, the electrical connection mechanism is suitable for electronically connecting the first module and the second module in a signal, information and / or power transmission mode (when the connector is attached to the first module and the second module arranged side by side). This allows the two modules (the first module and the second module) to communicate and / or exchange power. Therefore, no additional cable connection is required. The system is cost-effective. Further, none of the cable terminals of the modules hinders the connection of two adjacent modules. The cable terminals can be used to connect external devices, such as sensors, actuators, compressors, robots and / or the like. Therefore, there is good flexibility for connecting a large number of external devices to the automation controller system, especially to the first module and / or the second module. In addition, the cable terminals required to connect the two modules can even be replaced by different cable terminals (i.e., I / O connectors for connecting external devices (such as sensors and / or operating components)).

[0034] According to another aspect, the electrical connection mechanism includes a (first) electrical interconnection terminal at a first module and a (second) electrical interconnection terminal at a second module, wherein the connector includes a conductive component for connecting the first interconnection terminal with the second interconnection terminal (when the connector is installed in the first module and the second module, i.e., when the connector is attached to the two modules in a predetermined final position).

[0035] In a preferred embodiment, the electrical connection mechanism includes a (first) female pin socket at the first module (as an electrical interconnection terminal at the first module) and a (second) female pin socket at the second module (as an electrical interconnection terminal at the second module), wherein the connector includes a U-shaped pin assembly for connecting the first female pin socket with the second female pin socket. The pin assembly connects the female pin socket of one module with the female pin socket of another module, thereby generating at least one electrical connection between the two modules. In this embodiment, the pin assembly constitutes a conductive assembly of the connector. The assembly is easy to install and disassemble.

[0036] The pin assembly may include, for example, four to twenty pins. Each of the female pin sockets may include a corresponding number of pin mounts.

[0037] In one embodiment, the connector is configured to allow limited movement of the U-shaped pin assembly relative to the connector housing. Thus, any type of tolerance of the connector and / or positioning tolerance of the header pin socket can be compensated, thereby allowing a reliable connection between the first module and the second module. The movement allows easy assembly of the connector even if the header pin sockets of the first module and / or the second module are not properly aligned. Thus, assembly of the connector is easy.

[0038] The electrical connection mechanism can be configured to establish multiple separate electrical connections between the first module and the second module via the connector (e.g., via a pin assembly) when the connector is inserted into the first mounting portion and the second mounting portion (i.e., when the connector is installed in a predetermined final position between the modules). The number can be at least two, for example, at least four. Additionally or alternatively, the number can be a maximum of twenty-four, for example, a maximum of twelve. Some of the separate electrical connections (e.g., at least two) can be configured for data bus and / or network connections between these modules. Additionally or alternatively, some of these separate electrical connections can be configured for power transmission between these modules. Thus, one of these modules can supply power for operation to another module. According to another aspect, some of the electrical connections can be configured to independently transmit specific electrical signals, such as electrical signals related to stepper motor control.

[0039] In a preferred embodiment, the system is configured so that the connector is inserted into the first and second mounting parts substantially simultaneously, making the assembly process easy to manipulate. "Substantially" may mean that the connector is connected to the first and second mounting parts in one single movement.

[0040] According to another aspect, the second module may include a second engaging portion and a (further) first engaging portion. Additionally or alternatively, the first module may include both the first engaging portion and the further second engaging portion. Thus, a plurality of modules may be connected in series with each other via a corresponding number of connectors (the number of controller modules minus one). Accordingly, the system may include at least three controller system modules and at least two connectors.

[0041] In one embodiment, the system includes an end connector for a first mounting portion (referred to as a "right end connector"). The right end connector is configured to be received in the first mounting portion. The right end connector may include a cable connector assembly for connecting at least one cable thereto. The right end connector may be configured to electrically connect the corresponding controller system module to its cable connector assembly when the right end connector is inserted into the first mounting portion. The right end connector may include a pin assembly configured to engage a first female pin socket (when inserted into the first mounting portion). The right end connector may include a mechanical portion corresponding to a portion of an engagement mechanism on the connector for engaging with the first mounting portion. The housing of the right end connector may be substantially identical to the connector housing of the connector. For example, a portion corresponding to at least 60% of the mass of the housing of the right end connector may be identical to the connector housing of the connector.

[0042] Additionally or alternatively, the system includes an end connector for a second mounting portion (referred to as a "left end connector"). The left end connector is configured to be received in the second mounting portion. The right end connector may include a pin assembly configured to engage a second female pin socket (when inserted into the second mounting portion). The left end connector may include a cable connector assembly for connecting at least one cable thereto. The left end connector may be configured to electrically connect a corresponding controller system module to its cable connector assembly when the left end connector is inserted into the second mounting portion. The left end connector may include a mechanism corresponding to a portion of an engagement mechanism on the connector for engaging with the second mounting portion. The housing of the left end connector may be substantially identical to the connector housing of the connector. For example, a portion corresponding to at least 60% of the mass of the housing of the left end connector may be identical to the connector housing of the connector.

[0043] Furthermore, the above mentioned problem is solved by a method according to claim 9. Preferred embodiments are disclosed in the dependent claims.

[0044] The method comprises using a system according to any of the embodiments described elsewhere. Modifications and advantages described with respect to the system apply correspondingly to the method and vice versa.

[0045] The connector housing is inserted into the first mounting portion of the first module and into the second mounting portion of the second mounting portion, so that the modules are electrically connected to each other via the electrical connection mechanism. Thus, the modules are connected to each other by placing only one connector housing in both mounting portions. This is easy, cost-effective and not prone to error.

[0046] In one embodiment, the connector housing is inserted into the first mounting portion and the second mounting portion substantially simultaneously. The connector housing is inserted into the first mounting portion and the second mounting portion in one single movement, making the assembly process shorter.

[0047] In one embodiment, the connector is one-handed. By installing the connector using only one hand, the other hand is free. Thus, the person installing the connector can hold something else, or even hold a second connector to connect two modules in a subsequent step. This is time efficient and therefore cost efficient.

[0048] In one embodiment, the connector is inserted along an insertion direction from the top side of the controller system module toward the guide rail, perpendicular to the guide rail, wherein the top side faces away from the guide rail. The guide rails can be arranged in multiple rows spaced vertically from each other so that there is only limited space between each row. Therefore, the connector can be easily inserted from the top side toward the guide rail.

[0049] The above mentioned problem is further solved by a controller system module (eg, an automation controller system module) for use in a system according to any one of the above mentioned embodiments.

[0050] The controller system module includes at least one of the first mounting portion and the second mounting portion and a corresponding electrical interconnect terminal for connecting with a conductive component of the connector when the connector is mounted on the controller system module.

[0051] The electrical interconnection terminal may be a pin connector assembly, such as a female pin socket.

[0052] In one embodiment, the controller system module includes

[0053] - a first mounting section (configured to form part of the first receiving portion and for mounting the right end connector) and a corresponding first electrical interconnection terminal (eg, a first female pin socket), and

[0054] - A second mounting portion (configured to form a portion of the second receiving portion and for mounting the left end connector) and a corresponding second electrical interconnection terminal (eg, a second female pin socket).

[0055] According to one aspect, the controller system module may include snap-lock feature(s) for snap-locking a snap member of the connector when the first portion of the connector is received in the first mounting portion.

[0056] Additionally or alternatively, the controller system module may include snap-lock feature(s) for snap-locking a snap member of the connector when the first portion of the connector is received in the second mounting portion.

[0057] In one embodiment, a controller system module is used in a system having at least the features according to claim 4 and claim 7, wherein the controller system module comprises at least one of the snap-lock features, and at least one female pin socket.

[0058] The above mentioned problem is further solved by a connector for a system according to any one of the above embodiments, wherein the first electrical interconnection terminal is formed at the first module and the second electrical interconnection terminal is formed at the second module.

[0059] The connector includes a conductive assembly for connecting the first electrical interconnection terminal with the second electrical interconnection terminal when the connector is mounted to the first module and the second module.

[0060] The conductive component of the connector may be a U-shaped pin component.

[0061] In one embodiment, the connector includes a connector housing and an elastic snap member on the connector housing.

[0062] According to another aspect, the connector may include one, several or all of the following features described elsewhere:

[0063] - a projection guide for the first mounting part,

[0064] - a tongue and groove section for the first mounting part,

[0065] - a locking feature for the first guide portion,

[0066] - a lancet projection for the first guide portion,

[0070] - a lancet projection for the second guide portion,

[0071] - two protection plates for protecting the conductive components, and

[0072] - Actuable top section.

[0073] In one embodiment, a connector is used in a system having at least the features according to claim 3 and claim 7, wherein the connector comprises an elastic snap member and a U-shaped pin assembly.

[0074] The above problem is further solved by an end connector for a system according to any one of the above embodiments, wherein at at least one of the first mounting portion and the second mounting portion, an electrical interconnection terminal is formed on a corresponding controller system module,

[0075] wherein the end connector is adapted to be releasably mounted to one of the first mounting portion and the second mounting portion,

[0076] The end connector includes a cable connector assembly for connecting at least one cable thereto, and a conductive assembly for connecting an electrical interconnection terminal at one of the first mounting part and the second mounting part to the cable connector assembly when the end connector is installed to one of the first mounting part and the second mounting part.

[0077] The end connector can be a right end connector or a left end connector, as described elsewhere.

[0078] The conductive assembly may include end pins for contacting electrical interconnect terminals at one of the first mounting portion and the second mounting portion.

[0105] Figure 1 A plurality of controller system modules 1 of a controller system mounted on a rail 2 are shown. The rail 2 is a standardized equipment rail, such as a DIN rail or the like. Adjacent controller system modules 1 are mechanically and electrically connected, respectively, via an intermediate connector 3. The rail 2 is typically mounted on a wall (not depicted) and / or in a controller cabinet, wherein a plurality of rails 2 may be mounted vertically spaced apart from each other to form a plurality of rows. The controller system modules 1 of the same row may be connected to adjacent controller system modules using the intermediate connector 3, and the controller system modules 1 at the far right or far left of each row may be connected across the row via the end connector 4.

[0106] The terms "connector" and "connector housing" may be used synonymously hereinafter. "Controller housing" and "controller system module" may also be used synonymously hereinafter.

[0107] One of the controller system modules 1 is equipped with a top unit 5 which can be used to control, service or maintain the settings of the controller system module 1. The top unit 5 comprises a display (not depicted) and a user input device with a plurality of buttons 6 by which service personnel can interact with the controller system module 1.

[0108] The controller system module 1 includes a plurality of external connectors 7. The external connectors include, for example, a cable connection clip and an RJ-45 housing. The external connectors 7 are arranged on opposite sides of the controller system module 1.

[0109] The controller system module 1 may be an electronic controller module, an I / O module and / or a power supply module, wherein the controller system module 1 may control external components, such as actuators, compressors, etc., not depicted. Further, one or more of the controller system modules 1 may be connected to sensors (not depicted). Based on information provided by the sensors, the controller system module 1 is able to determine control information for controlling the external components.

[0110] Figure 2 A controller system module 1 is depicted, wherein a top unit 5 is mounted on the top side of the controller system module 1. The controller system module 1 comprises a number of cable terminals 7, which include two Ethernet ports (e.g., RJ-45 jacks or GG-45 jacks). Further, Figure 2 The controller system module 1 depicted is connected to the end connector 4.

[0111] Figure 3A controller system module 1 is shown with a plurality of cable terminals 7 and a first mounting portion 8. The first mounting portion 8 comprises: a female pin socket 9; a snap-lock feature for snap-locking the snap members of the connectors 3, 4; and a guide member, wherein the guide member comprises a protruding guide 10 and a tongue-and-groove section 11.

[0112] Figure 4 A top view of a controller system module 1 is depicted, the controller system module comprising a first mounting portion 8 (in Figure 4 on the left side) and the second mounting portion 12 (on the Figure 4 on the right side of the guide rail 2). Each mounting portion 8, 12 includes: a corresponding female pin socket 9, a protrusion guide portion 10, and a tongue-and-groove section 11. The first mounting portion 8 and the second mounting portion 12 are mirror-symmetrical to each other about the middle plane of the controller system module 1, and the middle plane divides the controller system module 1 into a left half and a right half. When the controller system module 1 is attached to the guide rail 2, the middle plane is perpendicular to the guide rail 2. The first mounting portion 8 and the second mounting portion 12 of the same controller system module 1 can be symmetrical about the middle plane of the controller system module 1, while the first mounting portion 8 and the second mounting portion 12 are asymmetrical about a plane perpendicular to the middle plane parallel to the longitudinal direction of the guide rail 2. The controller system module 1 further includes on opposite sides (i.e., on Figure 4 Several cable terminals 7 on the upper and bottom sides).

[0113] Figure 5 The first mounting portion 8 is depicted in more detail. The first mounting portion 8 comprises a protruding guide 10 and a tongue section 11 which interact with corresponding features of the connectors 3, 4. Further, the controller system module 1 comprises a snap-lock feature for snap-locking a snap member of the connectors 3, 4. The snap-lock feature comprises a recess 13 or is formed as a recess into which the snap member can be snap-locked so that the connectors 3, 4 are detachably held. The tongue section 11 comprises a tapered geometry.

[0114] If the connectors 3 , 4 are inserted into the mounting portion 8 , the connectors 3 , 4 are reliably guided to a predetermined final position.

[0115] The protrusion guide 10 may comprise a hole in a printed circuit board of the controller system module 1. If the connector 3 is in the predetermined final position, the corresponding spike protrusion 14 may protrude far enough that a portion of the spike protrusion 14 extends through the hole in the printed circuit board.

[0116] Assume that two of the controller system modules 1 (the first controller system module and the second controller system module) are installed side by side on the guide rail 2, such as Figure 4 and Fig.11As shown, the mounting portion 8 of the first controller system module is located at the end portion of the first controller system module facing the second controller system module 1. Vice versa, the second mounting portion 12 of the second controller system module 1 is located at the end portion of the second controller system module facing the first controller system module. Then, the two mounting portions 8, 12 are positioned directly adjacent to each other and together form a receiving portion for (together) receiving a single intermediate connector 3. By inserting the intermediate connector 3 into the receiving portion, two adjacent controller system modules 1 are directly mechanically and electrically connected via the intermediate connector 3. Since the intermediate connector 3 is releasable, the mechanical connection and the electrical connection are also releasable. It is very easy to establish a connection, and the connection is reliable. The connection uses space that would otherwise not be effectively used.

[0117] Figure 6 A stereogram is provided, which shows that the connector 3 has a mechanical pin protrusion 14 (hereinafter also referred to as a piercing protrusion 14) extending on the (contact) pin 15. In other words, the piercing pin 14 protrudes further than the (contact) pin 15. The (contact) pin 15 can be formed in a U-shape, so that two opposite pins 15 are actually two ends of one U-shaped pin 15. The connector 3 includes an elastic snap member (elastic member 16), which is bendable under pressure, but returns to its initial state if no pressure is applied. The elastic member 16 includes two elements (locking features 16a), which are displaced if the elastic member 16 is deformed. In the installed state, each of the two elements is arranged in one of the snap-lock features (respectively, the recess 13). The pin 15 can be moved to a certain extent relative to the housing of the connector 3. Thereby, misalignment between the female pin socket 9 and the connector 3 can be compensated. Such misalignment may be caused by various tolerances.

[0118] The connector 3 comprises a top section 19 which can be actuated by a user, wherein actuation of the top section 19 causes a deflection of the elastic member 16. The actuation is performed by pressing a first end side 19a of the top section 19 and a second end side 19b of the top section 19 opposite to the first end side 19a towards each other. For example, the user can place one finger on the first end side 19a and another finger (in particular another finger of the same hand) on the second end side 19b and press the fingers in a direction towards each other. The first end side 19a and the second end side 19b can be the end sides of the top section 19 in a direction perpendicular to the insertion direction and parallel to the center plane 17.

[0119] like Figure 7 As provided, the intermediate connector 3 is mirror-symmetrical about a center plane 17 (dashed line). As mentioned above, the contact pins 15 are formed in a U-shape, wherein the U is open toward the bottom of the drawing.

[0120] Two protection plates 24 for protecting the contact pins 15 protrude on the side of the connector 3 opposite to the top section 19 (i.e. the side of the connector 3 facing the rail 2 when the controller system module is mounted on the rail 2 and the connector 3 is mounted in the receiving portion). The protection plates 24 ensure that the risk of accidental deformation of the contact pins 15 is reduced. The protection plates 24 can protrude further in the insertion direction than the contact pins 15. The piercing protrusions 14 can protrude further in the insertion direction than the protection plates 24.

[0121] Each puncture protrusion 14 interacts with a corresponding protrusion guide 10 of the mounting parts 8, 12. The connector 3 includes further protrusions 18, which are configured to interact with corresponding tongues and grooves 11 of the mounting parts 8, 12 at least in a state where the connector 3 is connected to the first controller system module and the second controller system module 1. The tapered geometry of the tongue and groove section 11 interacts with the protrusions 18 so that the controller system modules 1 connected via the intermediate connector 3 are pulled together, thereby forming a tight connection between the controller system modules 1. Further, the tapered geometry of the tongue and groove section 11 and the corresponding tapered shape of the protrusions 18 hold the intermediate connector 3 (and the second controller system module 1) together when inserted into the first mounting part 8. Figure 8 The end connector 4) shown is guided into a predetermined final position.

[0122] The resilient member 16 may bend toward the protrusion 18 so that it may overcome the snap-lock feature 13 (respectively, the notch) of the mounting portion 8 , 12 .

[0123] Figures 8 to 10 An end connector 4 is depicted, which includes two piercing protrusions 14, a resilient member 16, a protrusion 18, an end (contact) pin 20, and a cable connector 21 (cable connector assembly). The piercing protrusions 14, the resilient member 16, and the protrusion 18 are formed to be equivalent to the piercing protrusions, the resilient member, and the protrusion of the intermediate connector 3 described above. The end pin 20 is connected to the cable connector 21 so that a cable (not depicted) connected to the cable connector 21 communicates with the controller system module 1 via the end connector 4 (if the end connector is inserted). The number of end pins 20 may be different from the number of cable connectors 21.

[0124] The connector housing of the end connector 4 is similar to the housing of the intermediate connector 3. Only the area in which the cable connector 21 is located is different. This allows cost-effective production.

[0125] The end connector 4 is asymmetrical. Figures 8 to 10The end connector 4 shown is a right end connector 4. The right end connector 4 is adapted to be mounted in the first mounting portion 8. Naturally, the system may alternatively or additionally include a left end connector adapted to be mounted in the second mounting portion 12. Compared to the right end connector 4, the left end connector 4 may be mirror-symmetrical with respect to the center plane 17.

[0126] Similar to the intermediate connector 3 , the end connector 4 includes a top section 19 which deflects the elastic member 16 when the top section 19 is operated.

[0127] The cable connector 21 has, for example, the following poles: ID, high, low, 14 V and GND (ground). Different pole assignments are also possible. The number of cable connectors 21 can be different depending on the electrical transmission requirements. Further, depending on the electrical transmission requirements, more or fewer end pins 20 can be provided and connected to the cable connector 21.

[0128] Fig.11 A cross-sectional view in the longitudinal direction of the guide rail 2 is depicted, showing the guide rail 2, two controller system modules 1, an intermediate connector 3 and an end connector 4. The lancet protrusions 14 of the intermediate connector 3 protrude into the corresponding protrusion guides 10 to form a mechanical connection between the connector 3 and the corresponding controller system module 1.

[0129] The intermediate connector 3 comprises U-shaped pins 15 held by pin holders 22. The pin holders 22 allow a certain degree of movement of the pins 15, making it possible to compensate for positioning tolerances of the female pin sockets 9 relative to the intermediate connector 3. The pin holders 22 are housed in the connector 3, respectively in the connector housing thereof.

[0130] The end connector 4 includes end (contact) pins 20 held by an end pin holder 23. Each of the end pins 20 is connected to one of the provided cable connectors 21 so that the end pin 20 can be electrically connected to a cable not depicted. The end connector 4 further includes two pin protrusions 14. One piercing protrusion 14 of the end connector 4 protrudes into a corresponding protrusion guide 10 of the controller system module 1 to which the end connector 4 is mounted. The other piercing protrusion 14 of the end connector 4 at the side with the cable connector 21 is free to hang.

[0131] The female pin socket 9 of each connector 3 , 4 is connected to non-depicted internal components of the connector 3 , 4 , for example to any type of circuit board, processor, power system and / or the like.

[0132] The lancet protrusion 14 interacting with the protrusion guide 10 , the projection 18 interacting with the tongue section 11 , and the snap connection constitute a coupling mechanism.

[0133] The intermediate connector 3 is mounted to two controller system modules 1 as follows: the two controller system modules 1 are arranged close to each other on the same guide rail 2, wherein the controller system modules 1 are close together so that the controller system modules 1 touch or are spaced less than 2 mm apart. In a subsequent step, the connector 3 is inserted into the adjacently arranged mounting portions 8, 12 of the two controller system modules 1. The connector 3 is inserted along the insertion direction, for example, pushed into the receiving portion. The insertion direction is oriented from the top side of the controller system module 1 toward the guide rail 2. The insertion direction is perpendicular to the guide rail 2. The connector 3 interacts with the two controller system modules 1 substantially simultaneously during the insertion process. There is no significant delay between installing the connector 3 to one of the two controller system modules 1 and installing it to the other. The puncture protrusion 14 interacts with the protrusion guide 10, and the protrusion 18 interacts with the tongue and groove section 11. During the insertion process, the elastic member 16 of the connector 3 is deflected so that the locking feature 16a provided on the elastic member 16 is snapped into the snap-locking feature (correspondingly, the recess 13 of the controller system module 1). The U-shaped pins 15 are introduced into the female pin sockets 9 of the adjacent controller system modules 1 and electrically connect these female pin sockets 9 (and thus the adjacent controller system modules 1). This connection can allow data transmission and / or power transmission. The intermediate connector 3 is held in a predetermined final position by a snap-on connection.

[0134] To remove the intermediate connector 3 from its predetermined final position (connected position), the resilient member 16 is deflected so that the snap connection is disengaged. The resilient member 16 can be tool-free deflectable, wherein the top portion 19 of the connector 3 is actuated to a disengaged state. In this embodiment, the locking feature 16a is withdrawn from the recess 13. Subsequently, the intermediate connector 3 can be removed by pulling away from the controller system module 1 in a direction opposite to the insertion direction.

[0135] In order to mount the end connector 4 on a side of the controller system module 1, where no further controller system modules 1 are arranged on this side, the spike protrusion 14 on the side opposite to the cable connector 21 is arranged to interact with the protrusion guide 10, while the protrusion 18 on the same side interacts with the tongue section 11. During the installation process, the elastic member deflects so that the end connector 4 can be pushed into its installation position (its predetermined final position). At a certain point, the deflection of the elastic member 16 snaps back so that the locking feature 16a on the side opposite to the cable connector 21 is snapped into the snap-lock feature (respectively, the corresponding recess 13). The cable can be connected to the cable connector 21 before or after the end connector 4 is mounted to the controller system module 1.

[0136] Removal of the end connector 4 is performed in accordance with removal of the intermediate connector 3, as described above.
