A surface-mountable electrical circuit protection device includes layers defining a first PPTC resistive element, a second PPTC resistive element, and at least one heat-generating electrical component such as a planar zener diode chip positioned between, and in thermal contact with, the first and second PPTC elements, such that an electrical current above a threshold level passing through the component causes the component to heat, the heat being transferred to the PPTC resistive elements and tripping at least one, and preferably both of the first or second PPTC elements to a high resistance state. A series of edge-formed terminal electrodes enable surface-mount connection of the first and second PPTC elements and the electrical component to an electrical circuit substrate, such as a printed circuit board. A method for making the device is also disclosed.

The present disclosure provides a magnet device for providing the magnetic density changes/magnetic field changes in relation to a detecting position. The magnet device comprises a magnet member adapted to be mounted on a rotatable shaft and be rotated for producing the magnetic density changes/magnetic field changes in relation to the detecting position when the magnet member is rotating around the rotatable shaft. To concentrate/condense the density of the magnetic density changes/magnetic field changes, the magnet device includes a magnetic flux density concentrator.

A leadframe for a contact module includes signal contacts arranged in pairs carrying differential signals. Each pair of signal contacts includes a first signal contact and a second signal contact. Each signal contact has a mating beam at an end thereof configured to be electrically connected to a corresponding header contact of a header assembly. Each mating beam includes a stem and a branch extending from the stem. A first paddle extends from the stem and a second paddle extends from the branch. In an initial, stamped orientation, the mating beams are stamped such that the mating beams of the first and second signal contacts within the same pair of signal contacts are angled non-parallel to one another.

A cable assembly for a cable backplane system includes a tray having a frame and spacer assemblies coupled to the frame that hold cable tray connectors in fixed positions relative to the frame. Each cable tray connector has a housing holding a plurality of contacts and cables extending rearward from the corresponding housing. The housings are configured to be received in corresponding openings in a backplane of the cable backplane system. A flexible cable harness extends from the tray. The flexible cable harness has a flexible shield electrically coupled to the frame and a harness connector electrically connected to at least one corresponding cable tray connector. At least some of the cables are routed from the tray through the flexible shield to the harness connector. The flexible shield provides electrical shielding for the cables. The harness connector is variably positionable relative to the tray.

A contactless connector includes a waveguide structure having a waveguide body extending between a first end and a second end and a septum received in the waveguide body and extend at least partially along an interior of the waveguide body. The septum divides at least a portion of the waveguide body into a first chamber and a second chamber. The waveguide structure conveys RF signals between the first and second ends. The contactless connector includes a communication module having a circuit board positioned at the first end of the waveguide body with transmit and receive communication chips coupled to the circuit board. The waveguide guides the RF signals from and to the transmit and receive communication chips, and the septum isolates the RF signals associated with the communication chips.

A flexible circuit board connector includes a contact having a separable mating interface mounted to a contact pad of a flexible circuit board and a terminating end terminated to a wire. A housing holds the contact and has a main body including a wire barrel configured to receive the wire. A clip is coupled to the housing with an intermediate space between the clip and the main body. The clip is movable between an open position and a closed position. The intermediate space is configured to receive the flexible circuit board when the clip is in the open position, and the clip and housing are configured to capture the flexible circuit board when the clip is in the closed position. The spring beam is configured to be electrically connected to the contact pad when the clip is in the closed position.

Electrical connector including a connector body having a mating side with a communication array of signal and ground contacts and first and second mounting sides with respective mounting arrays of signal and ground contacts. Each of the first and second mounting sides is configured to be mounted to a corresponding circuit board. The connector body includes signal and ground conductors that extend through the connector body and communicatively couple the communication array to each of the mounting arrays. The mating side faces along a mating axis and the first and second mounting sides face in opposite directions along a mounting axis. The mating and mounting axes are perpendicular to each other.

A connector assembly may include a housing that retains one or more contacts, a cable having a shield that surrounds one or more conductors that electrically connect to the one or more contacts, and a backshell that secures the housing to the cable. The backshell may include at least one wall having a backshell outer surface and a backshell inner surface, and one or more through-holes formed through the at least one wall. Each through-hole forms a current path between the backshell outer surface and the backshell inner surface.
