Embodiments of the invention include LED lighting systems and methods. For example, in some embodiments, an LED lighting system is included. The LED lighting system can include a flexible layered circuit structure that can include a top thermally conductive layer, a middle electrically insulating layer, a bottom thermally conductive layer, and a plurality of light emitting diodes mounted on the top layer. The LED lighting system can further include a housing substrate and a mounting structure. The mounting structure can be configured to suspend the layered circuit structure above the housing substrate with an air gap disposed in between the bottom thermally conductive layer of the flexible layered circuit structure and the housing substrate. The distance between the layered circuit structure and the support layer can be at least about 0.5 mm. Other embodiments are also included herein.

A multiple board standoff for interconnecting a plurality of electronic boards, such as printed circuit boards, having at least one keyhole slot. The standoff comprises a plurality of major diameter portions, a plurality of minor diameter portions each disposed between two of the plurality of major diameter portions, and a plurality of abutment surfaces each transversely extending from one of the major diameter portions to one of the minor diameter portions. At least one of the minor diameter portions is configured to be inserted into the keyhole slot when the standoff is in a first orientation with respect to the electronic board and being retained within the keyhole slot when the standoff is in a second orientation with respect to the electronic board.

A resilient electrical connector assembly includes a base PCB and stacked layers of interconnected resilient conductive structures where each structure has at least two resilient conductive strips and at least two conductive contacts. One contact is integrated with a conductive path on the base PCB and another contact pad is positioned to establish a conductive path with a target PCB when the latter is mounted parallel to the base PCB. The resilient conductive strips flex due to a compressive force exerted between the base PCB and target PCB on the stacked layers. The resilient conductive structures are formed by depositing metal to sequentially form each of the stacked layers with one contact being initially formed in engagement with the conductive path on the base PCB.

A RJ connector assembly having the characteristics of simple structural design, effective and rational use of space and compact structure is disclosed to include an input PCB module including an input PC board and two RJ modular terminal blocks bonded to two opposite sides of the input PC board, an output PCB module including an output PC board disposed in parallel to the input PC board and an output interface located on the output PC board, and a connecting PCB module including a connecting PC board with a top side thereof electrically bonded to the input PC board and an opposing bottom side thereof electrically bonded to the output PC board.

A power contacting device includes a contact pin (1) and at least one contact pin receptacle (2) penetrated by the contact pin in the operating state. To provide a power contact which permanently ensures high-quality contacting, even when the contacted components move relative to one another, the contact pin receptacle (2) has a first guide arrangement (3) which is fixed to a component in the operating state and a second guide arrangement (4) which is conductively connected to the first guide arrangement, the second guide arrangement (4) being arranged displaceably on the first guide arrangement (3) and the contact pin (1) conductively contacting at least the second guide arrangement (4) in the operating state.

An electrical connector for mating with the CPU unit, includes an insulative housing with a plurality of passageways extending therethrough in the vertical direction. A plurality of contacts are disposed within the corresponding passageways, respectively. Each contact includes opposite first retaining section and second retaining section with an upward resilient contacting section linked therebetween, and a soldering section extending downwardly from the first retaining section. The contacting section includes opposite first contacting part unitarily extending from the first retaining section, and second contacting part unitarily extending from the second retaining section. The CPU unit forms a plurality of metal-coated recesses in an underside to receive the contacting section of the corresponding contacts, respectively. The first retaining section is essentially immovable in the passageway while the second retaining section is essentially movable relative to the housing in response to mating with the CPU.

A connector includes a rectangular flat-plate housing including a first positioning hole and a second positioning hole, and a contact row and a contact row held on the housing. The housing includes a first pitch side surface and a second pitch side surface on an opposite side of the first pitch side surface. The contact row and the contact row extend from the first pitch side surface to the second pitch side surface. The first positioning hole is disposed between the first pitch side surface and the contact row, and the second positioning hole is disposed between the first pitch side surface and the contact row.

A connector includes a metal cylinder with three or more slots cut from a first end and three or more slots cut from a second end which are intercalated between the slots from the first end, whereby the connector is radially compressible along its entire length. The connector is adapted for insertion at one end into a hole in a circuit board, thereby making electrical contact to traces in the circuit board.

Electrically insulated connector bands for Downhole Electrical Disconnect Tools provide power and/or data communication downhole are made from metal having sufficient strength and corrosion resistance to eliminate the need of any vacuum and sealed pressure compensation assembly while being exposed to wellbore fluids. The electrical insulation is achieved by having portions of the connector bands coated with electrically insulating material. An uncoated section of each connector band will provide the electrical path between the male and female mandrels.

An electro-optic display may comprise a front electrode having a first opening defined therein, a rear electrode having a second opening defined therein, an electro-optic layer between the front and rear electrodes and a rigid conductive component passing through the first and second openings and electrically contacting the front electrode but not the rear electrode.
