Description

[0001] The invention relates to a device, a circuit board for a device, a socket for a device and a method for assembling a device.

[0002] According to Commission Implementing Regulation (EU) 2016 / 799 of 18 March 2016 implementing Regulation (EU) No 165 / 2014 of the European Parliament and of the Council laying down the requirements for the construction, testing, installation, operation and repair of tachographs and their components, digital tachographs must include a front-panel connector for calibration and downloading. Details of the front-panel connector are provided in Appendix 6 to the regulation. The tachograph download / calibration connector is a socket containing six pins. The plug associated with the tachograph download / calibration connector contains six sockets for accommodating the six pins.

[0003] A pin header comprising the six pins is typically attached to a printed circuit board of the tachograph. A plug-receiving cavity designed to receive the plug is typically provided by a tachograph housing. The common design suffers from several problems. The position and / or orientation of the pins on the printed circuit board may vary slightly. Accordingly, their position in the plug-receiving cavity may deviate from the intended position. During insertion of the plug into the plug-receiving cavity, the openings of the socket may not align with the pins and the plug may press against the pins. The pins may become bent and / or a connection between the pin header and the printed circuit board may become loose.Another disadvantage of current designs is time-consuming assembly when additional processes such as gluing or ultrasonic welding are required to attach the socket to the circuit board.

[0004] WO 2009043862 A1 describes a plug connection cover for a housing of an electrical plug connection, which comprises a first plug connection element and a second plug connection element which are connected to one another and is arranged such that at least a part of the housing of the electrical plug connection is accommodated therein, wherein the first plug connection element comprises at least one locking pin which is designed to engage a slot of an opening in a housing for fixing the plug connection cover to the housing.

[0005] CN 217011347 U discloses an installation box for an automotive seat memory adjustment control circuit, characterized by comprising an installation box sub-box B and an installation box cover A; wherein the installation box sub-box B and the installation box cover A are fixed to form an installation cavity used for installing a printed circuit board; wherein the installation box cover A is provided with at least one interface 1 on the cover surface, which is used for connecting the associated seat electrical components; wherein the opening of the interface 1 corresponds to the position of the pin row on the printed circuit board in the installation cavity; wherein the interface 1 corresponds to the position of the pin row on the printed circuit board in the installation cavity. The opening of the interface 1 corresponds to the position of the pin row on the printed circuit board in the mounting cavity.Advantageous effect: The circuit board is fixed in the mounting cavity to ensure the stability of the fixed position of the circuit board, the wall of the box is further fixed with a female locking part and a female locking part, a special pin hole for the pins is designed on the circuit board, and the edge of the interface protrudes outwards to maintain the durability of the interface during plugging and unplugging.

[0006] CN 212231827 U describes a controller, in particular comprising a housing and a printed circuit board, the housing comprises a first housing and a second housing, which has one end opening of the first housing, and the second housing shell connections in the open end of the first housing, is provided with the first sealing element which is used for the shutdown distance between the two between the first housing and the second housing.

[0007] It is an object of the present invention to provide a socket that provides mechanical stability to the pins and is easy to assemble on a circuit board.

[0008] This object is achieved by the subject matter of the independent claims. Advantageous further developments with useful and not irrelevant further embodiments of the invention are set forth in the dependent claims, the following description, and the drawings.

[0009] A first aspect of the present invention relates to a device comprising a circuit board and a socket. The device can be configured as a digital tachograph. The socket is attached to the circuit board at a predefined socket position, wherein the socket at least partially defines a plug-receiving cavity for receiving a corresponding plug. In other words, the socket is provided to connect the corresponding plug to the device. The plug-receiving cavity provided by the socket is shaped according to the corresponding plug to enable insertion of the plug into the socket.

[0010] The circuit board includes a pin header comprising pins, the pins being designed to connect to the respective sockets of the associated connector. The pin header is mounted at a predefined pin header position on the circuit board. In other words, the connector includes sockets that connect to the pins of the pin header on the circuit board.

[0011] The predefined strip position and the predefined socket position have a specific arrangement with respect to each other, with the pins of the strip having a predefined pin position in the socket to penetrate the sockets of the corresponding plug.

[0012] The circuit board comprises an assembly guide device which is designed to guide the socket into the predefined socket position along an assembly direction during an assembly process of the device.

[0013] The socket defines through holes configured to guide the pins into the predefined pin position in the plug receiving cavity during the assembly process of the device.

[0014] In other words, the circuit board and the socket are designed to allow a predefined assembly process of the device. In order to arrange the socket at the predefined socket position during the assembly process of the device, the circuit board comprises the assembly guide device. The assembly guide device and the socket are coordinated such that the socket can be guided along the predefined assembly direction. This ensures that the socket is guided along the predefined assembly direction into the predefined socket position. The through-holes of the socket and the pins of the strip are aligned such that the pins are guided into the predefined pin position relative to the plug-receiving cavity. The through-holes ensure that the pins are arranged in the predefined pin position in the plug-receiving cavity.The through holes also provide mechanical stability. As the socket is guided through the assembly guide, the pins are guided into the through holes.

[0015] The advantage of this device is that the pins are arranged by the can in the predefined pin position and the assembly guide device prevents damage to the pins during the assembly process.

[0016] The invention also includes embodiments that provide additional technical advantages.

[0017] According to a further embodiment of the invention, the assembly guide device comprises an assembly guide slot that extends from an edge of the circuit board into the circuit board along the assembly direction. In other words, the circuit board defines the assembly guide slot. The assembly guide slot extends from an opening at the edge of the circuit board along the predefined assembly direction over a slot length into the circuit board.

[0018] The assembly guide slot is configured to at least partially receive an associated central guide rib of the socket and to guide the associated central guide rib along the assembly direction during the assembly process of the device. In other words, the socket includes the central guide rib that corresponds to the assembly guide slot defined by the circuit board. The central guide rib of the plug receptacle can extend from a rear surface of the socket over a predetermined length and can have a thickness that allows the central rib to penetrate the assembly guide slot. This embodiment has the advantage of providing a simple solution for ensuring guidance of the socket along the assembly direction during the assembly process.

[0019] According to a further embodiment of the invention, the receptacle comprises a snap pin, wherein the snap pin is configured to snap into an associated snap opening defined by the circuit board to secure the receptacle to the circuit board when the receptacle reaches the predefined receptacle position during the assembly process. In other words, it must be ensured that the receptacle is attached to the circuit board when the receptacle reaches the predefined receptacle position during the assembly process. The snap pin can extend from a rear surface of the receptacle over a predefined length. The associated snap opening defined by the circuit board can be arranged at a predefined distance from the edge of the circuit board.The length of the locking pin and the distance of the locking hole from the edge of the receptacle are coordinated such that the locking pin snaps into the corresponding locking hole when the receptacle reaches the predefined receptacle position during movement of the receptacle along the assembly direction. This design has the advantage of providing a simple solution for locking the receptacle when it reaches the predefined receptacle position. Accordingly, it is not necessary to screw the receptacle to the circuit board, which facilitates the attachment of the receptacle to the circuit board during assembly.

[0020] According to a further embodiment of the invention, the socket is supported by an edge of the circuit board against forces acting on the socket in the assembly direction. In other words, a rear side of the socket is supported against forces acting on the socket in the assembly direction. Forces acting on the socket in the assembly direction can occur when the associated plug is inserted into the socket. Since the force acting on the socket is the force with which the socket is supported by the edge of the circuit board, it is ensured that the force does not act on the pins or the pin header of the circuit board, thus preventing damage to the pin header during insertion of the associated plug into the plug receiving cavity.

[0021] According to a further embodiment of the invention, the socket is supported by the edge of the circuit board via a spacer rib against the forces acting on the socket in the assembly direction. In other words: The box includes the spacer rib, which can extend from the rear of the outlet over a predefined length, and the spacer rib can be supported by the edge of the circuit board. Accordingly, the position of the support can be defined by the spacer rib. The spacer rib can have a length defined such that the spacer rib touches the edge, or can have the predefined distance from the edge when the outlet is arranged in the predefined outlet position.

[0022] According to a further embodiment of the invention, the socket comprises a support rib protruding from an inner side of the socket. The support rib is designed to support the socket against a surface of the circuit board. The provision of the support rib has the advantage that the socket is supported against forces by a surface of the circuit board. The support rib can extend over a predetermined length to allow guidance of the socket along the predetermined assembly direction during the assembly process, and the socket can be arranged according to the predetermined plug position.

[0023] According to a further embodiment of the invention, the through-holes provide cones at respective inner openings of the through-holes that are oriented toward the circuit board to guide the pins into the through-holes during the assembly process. In other words, the through-holes have openings that open toward the circuit board, so that the embodiment has the advantage of facilitating the insertion of the pins into the through-holes. This has the advantage of preventing damage to the pins and allowing the pins to be bent and guided during the assembly process to correct any pin misalignments.

[0024] According to a further embodiment of the invention, the device comprises a housing in which the socket is arranged between the circuit board and a wall of the housing. The housing may comprise an opening to allow insertion of the associated plug into the plug-receiving cavity provided by the socket through the housing. The wall surrounding the opening may have dimensions such that insertion of the socket is possible and that the wall at least partially supports the socket. The housing comprises centering ribs protruding from the wall, wherein the centering ribs are designed to hold the circuit board in a predefined position.

[0025] According to a further embodiment of the invention, the device is designed as a digital tachograph.

[0026] A second aspect of the present invention relates to a printed circuit board for a device. The printed circuit board comprises a pin header comprising pins, the pins being configured to be connected to respective sockets of the associated plug, the pin header being mounted at a predefined pin header position on the printed circuit board. The printed circuit board comprises an assembly guide configured to guide a socket along an assembly direction into the predefined socket position during an assembly process of the device.

[0027] A third aspect of the present invention relates to a socket for a device. The socket at least partially defines a plug-receiving cavity for receiving a mating plug. The socket defines through holes configured to guide pins of a printed circuit board header into predefined pin positions in the plug-receiving cavity during an assembly process of the device.

[0028] A fourth aspect of the present invention relates to a housing for a device. A wall of the housing comprises an opening to allow insertion of a mating plug into a plug-receiving cavity provided by a socket through the housing. The wall surrounding the opening may be dimensioned to allow insertion of the socket and to at least partially support the socket. The housing comprises centering ribs projecting from the wall, the centering ribs being configured to hold the circuit board in a predefined position.

[0029] A fifth aspect of the present invention relates to a method for assembling a device. The method comprises inserting a socket into the predefined socket position on the circuit board.

[0030] For use cases or application situations that may occur within the scope of the method and which are not explicitly described here, it may be provided that - in accordance with the method - an error message and / or a prompt for user feedback is issued and / or default settings and / or a predefined initial state is / are set.

[0038] During insertion of the mating plug 16 into the plug-receiving cavity 14, forces may be exerted on the receptacle 12. The forces may act in the assembly direction 26. If the forces act on the pins 20, the pin header 18 may be damaged. Accordingly, the receptacle 12 may be supported by the edge 30 of the circuit board 11. The receptacle 12 may have a standoff rib 38. The standoff rib 38 may protrude from the inner surface 42 of the receptacle 12. The standoff rib 38 may contact the edge 30 of the circuit board 11 to support the receptacle 12 against forces acting on the receptacle 12 in the assembly direction 26.

[0039] The socket 12 may be designed to ensure that the pins 20 of the header 18 are arranged in the predefined pin positions in the plug-receiving cavity 14. The orientation and position of the pins 20 may vary within certain tolerance ranges. The socket 12 may provide the through-holes 48 for receiving the pins 20. The orientation and / or position of the pins 20 may change as the pins 20 are guided through the through-holes into the plug-receiving cavity.
