A floating connector assembly device is provided. An electronic component is mounted directly or indirectly to a chassis of an electronic device. At least one conductive contact spring is mounted to the electronic component and configured to electrically couple to the electronic component. A printed circuit board having a fixed end and a free end with an electrical contact positioned between the two ends is positioned against the conductive contact spring, the contact spring being biased so that a contacting portion of the contact spring contacts the electrical contact to form an electrical connection. The electrical connection is maintained during relative movement of the conductive contact spring and the electrical contact of the printed circuit board by a bias force of the conductive contact spring.

A board to board connector includes a first male connector and a second male connector. The first male connector includes a first number of pins. The second male connector is aligned with the first male connector and includes a second number of pins. The first male connector is configured to be removably electrically coupled to a first female connector including a third number of pins equal to the first number and the second male connector is configured to be removably electrically coupled to a second female connector including a fourth number of pins equal to the second number. The first male connector and the second male connector are also configured to be removably electrically coupled to a single third female connector including a fifth number of pins equal to the first number plus the second number.

An image display apparatus includes: a display panel; an LED substrate disposed on a back surface side of the display panel and on which an LED is mounted; a relay substrate disposed on the back surface side and on which a circuit unit is mounted; a first metal member disposed on the LED substrate and electrically connected with the LED; a second metal member disposed on the relay substrate, electrically connected with the circuit unit; and a reflective sheet that is electrically insulative and disposed between the display panel and both of the LED substrate and the relay substrate so as to cover at least the first metal member and the second metal member, the reflective sheet reflecting light from the LED toward a back surface of the display panel. When the first metal member and the second metal member are fitted with each other, an index hole is covered.

An adapter block assembly includes an adapter block, a circuit board arrangement, and a cover attached to the adapter block so that the circuit board arrangement is held to the adapter block by the cover. Contact assemblies can be disposed between the adapter block and the circuit board arrangement. The cover can be latched, heat staked, or otherwise secured to the adapter block. Each component of the adapter block assembly can include one or more parts (e.g., multiple adapter blocks, multiple circuit boards, and/or multiple cover pieces).

A circuit board module is electrically connectable to a socket by inserting one end part thereof into the socket, and includes a circuit board and a terminal board having a first surface provided with a column of socket-connection pads and mounted on the surface of the circuit board at the one end part. The terminal board includes first, second, and third pad columns provided on a second surface of the terminal board opposite to the first surface. The circuit board includes fourth, fifth, and sixth pad columns respectively provided on the surface of the circuit board opposing the second surface of the terminal board, at positions opposing the first, second, and third pad columns of the terminal board, respectively.

A circuit board with wire conductive pads is provided for insertion of wires, and includes: a circuit board and a wire conductive pad. The wire conductive pad includes a main body in the form of a hollow column and an elastic locking piece extending from the main body. The main body includes a peripheral wall defining an insertion space. The elastic locking piece is inserted from the peripheral wall into the insertion space in an inclined manner to press towards the peripheral wall. Wires are inserted into the insertion space and clamped against the peripheral wall by the elastic piece, so that the wires can be prevented from falling off in a reverse direction, and thus can be connected to the circuit board in a more quick and stable manner.

A segmental calendering device includes a framework, a pair of left-rolling sliding guide mechanism, a pair of right-rolling sliding guide mechanisms, an upper-calendering roller and a supporting mechanism of the upper-calendering roller, a lower-calendering roller as well as a pressing mechanism. The upper-calendering roller is rotatably supported within the supporting mechanism of the upper-calendering roller and disposed above a position between a left wallboard and a right wallboard of the framework, and the supporting mechanism of the upper-calendering roller slides along the pair of left-rolling sliding guide mechanisms and the pair of right-rolling sliding guide mechanisms. The lower-calendering roller is disposed below the upper-calendering roller correspondingly and rotatably supported between the left wallboard and the right wallboard. The pressing mechanism is for applying a pressure on the supporting mechanism of the upper-calendering roller and for adjusting the pressure.

A cable termination that provides low signal distortion even at high frequencies. Conductive elements of the cable are fused to edges of signal conductors in a cable connector or other component terminating the cable. For terminating a differential pair, the conductive elements of the cable may be terminated to opposing edges of a pair of signal conductors in the cable termination. The conductive elements may be shaped such that the spacing between signal paths passing through the conductive elements of the cable and into the signal conductors of the cable termination is uniform.

A modular electrical connector facilitates low loss connections to components on a printed circuit board. A portion is of the connector is formed of one or more first type units with conductive elements designed to be attached to a printed circuit board. Signals passing through those units may be routed to components on the printed circuit board through traces in the board. One or more second type units may be integrated with the connector. Those units may be designed for attachment to a cable, which may provide signal paths to a location on the printed circuit board near relatively distant components.

A segmental calendering device for a flexible flat cable is disclosed. The device includes a framework, a pair of left-rolling sliding guide mechanism, a pair of right-rolling sliding guide mechanisms, an upper-calendering roller and a supporting mechanism of the upper-calendering roller, a lower-calendering roller as well as a pressing mechanism. The upper-calendering roller is rotatably supported within the supporting mechanism of the upper-calendering roller and disposed above a position between a left wallboard and a right wallboard of the framework, and the supporting mechanism of the upper-calendering roller slides along the pair of left-rolling sliding guide mechanisms and the pair of right-rolling sliding guide mechanisms. The lower-calendering roller is disposed below the upper-calendering roller correspondingly and rotatably supported between the left wallboard and the right wallboard. The pressing mechanism is for applying a pressure on the supporting mechanism of the upper-calendering roller and for adjusting the pressure.
