In order to prevent a short-circuit failure between a conductive connecting portion (1) that is provided as a countermeasure against external electrical noises and an electronic circuit, a structure is adopted where a large number of electronic components (8) are mounted on a circuit board (5) that is mounted on a base (7), a metal cover (6) is disposed so as to cover upper portions of the electronic components (8), opening portions (3) are formed in the circuit board (5) at four positions on a periphery of the circuit board (5), protruding members (12) that are integrally formed with the base (7) are disposed at four positions respectively in alignment with the positions where the opening portions (3) are formed, the protruding members (12) are made to pass through the opening portions (3) at four positions from a back surface side of the circuit board (5) to protrude to a front surface side of the circuit board 5, the conductive connecting portions (1) are arranged in an outside direction with respect to the protruding members (12) at four positions on the board, the protruding members (12) are disposed between the conductive connecting portions (1) and the electronic circuit so as to electrically connect the metal cover (6), the conductive connecting portion (1), and a ground circuit to each other.

An electronic device having at least one circuit board. The circuit board has a predetermined pattern of solder bumps facilitating a ground connection with a first enclosure member and/or a second enclosure member. The at least one circuit board is sandwiched between the first and second enclosure members, each of the first and second enclosure members has a surface facing the circuit board and the surface facing the circuit board has a bead extending therefrom contacting the predetermined pattern of solder bumps to complete the ground connection.

A shield can for an electronic eyewear device is described that reduces RF signals emanating from the electronic eyewear device. The shield can is attached to a ground plate of the electronic eyewear device using leaf springs on a side of the shield can. The leaf springs do not add to the stack-up thickness of the shield can assembly and provide a balanced force against the ground plate. The shield can is attached to a printed circuit board and encompasses radio frequency (RF) electronic components to prevent RF signals emanating from the RF electronic components. The leaf springs have a pair of fingers providing the balanced mechanical point force. A conductive pressure sensitive adhesive is also provided to secure a top surface of the shield can to the ground plate along with a thermal paste.

The ground connection between the circuit card and the housing and the housing connection side is implemented by at least one plug-in connection of variable insertion depth. This design is particularly advantageous for producing corresponding devices in an automated manner because, owing to the assembly of the devices, the contact-connection of the circuit card to ground also takes place automatically, specifically as desired in the advantageous form of meshed grounding with simultaneous compensation of the housing tolerances which is made possible by the plug-in connection of variable insertion depth.

Apparatuses and associated methods for mounting PCBs and other electronics boards in portable medical equipment and/or other portable and non-portable electronic devices are disclosed herein. In some embodiments, the technology disclosed herein can provide PCB mounting systems that isolate the PCB from detrimental shock, vibration, and/or strain, while also providing electrical ground paths that greatly reduce EMI and other electrical disturbances. Some embodiments of the mounting systems described herein include both elastomeric (e.g., rubber) components and resilient metallic grounding members that, when assembled together, provide favorable shock mounting as well as robust electrical grounding without the inconvenience of using separate shock mounts, grounding straps, etc.

A PCB assembly includes a panel including at least one guide protrusion, at least one mounting portion, and at least one dislocation prevention protrusion, and a PCB including at least one guide hole formed to correspond to the at least one guide protrusion, at least one grounding portion formed to correspond to the at least one mounting portion, and at least one dislocation prevention hole formed to correspond to the at least one dislocation prevention protrusion, wherein the PCB is guided to slide by the at least one guide protrusion and the at least one guide hole, is brought into close contact with the panel by the at least one mounting portion and the at least one grounding portion, and fixed to the panel as the at least one dislocation prevention hole is supported by the at least one dislocation prevention protrusion.

A modularly expandable electronic control unit comprises: an electronic circuit board on which a conductor track is disposed on a side in a region of lateral edges and enclosing an inner region and separating it from an outer region of the side, a housing having two halves for receiving the electronic circuit board. With the housing assembled, at least one housing half has an encircling electrically conductive shielding wall which rests on and establishes electrical contact with the conductor track and/or has at least one receptacle accessible from outside the assembled housing. The receptacle is disposed so the electronic module placed in the receptacle may be electrically connected to a module connection port disposed in the outer region of the electronic circuit board. The electronic circuit board has electrical connections between the module connection port and one or more electronic assemblies disposed on the inner region.

The circuit board has a predetermined pattern of solder bumps facilitating a ground connection with a first enclosure member and/or a second enclosure member. The at least one circuit board is sandwiched between the first and second enclosure members, each of the first and second enclosure members has a surface facing the circuit board and the surface facing the circuit board has a bead extending therefrom contacting the predetermined pattern of solder bumps to complete the ground connection.

Exemplary arrangements relate to a housing part (100) for an electronic terminal such as a cell phone. The housing part is comprised of carbon fiber reinforced plastic and includes at least one conductive device such as a threaded metallic insert (110) configured for galvanic connection to the electronics that are housed within a housing of the terminal. In an exemplary arrangement the housing part includes a groove (120). The groove is filled with a conductive mass (130) which provides a galvanic connection to the exposed carbon fibers within the groove. The carbon fibers may thereby be in galvanic connection with the ground of the electronics within the housing part, which helps to suppress electronic noise which may be produced by the electronics.
