Abstract:
The invention relates to a pin (2) having a contact part that can be inserted into a receiving opening (20) in a circuit board (4) and anchored with a press fit in the receiving opening (20), and to a method for inserting a pin into a receiving opening (20) in a circuit board (4), wherein the pin (2) is inserted into the receiving opening (20) from one side of the circuit board (4) and a contact part (24) of the pin (2) is anchored in the receiving opening (20) with a press fit. According to the invention, the contact part (24) is inserted into the receiving opening (20) with no contact or with a sliding fit and subsequently deformed within the receiving opening (20) by expansion transversely to the insertion direction, in order to anchor it in the receiving opening (20) with a press fit.
Abstract:
A PC board (5) for mating with a card-edge connector (25) having a selectively configured projecting tab (10) which defines a desired insertion force profile to facilitate engagement. A portion (11) of the projecting tab (10) is notched to delay the initial contact from the internal spring contacts of the mating card-edge connector (25) until a proportional amount of contacts have opened and wiped some of the PC board terminals first, and then to allow the remaining contacts to engage the notched portion. Initial insertion force is relieved in proportion to the PC board edge profile.
Abstract:
A method and apparatus for automatically mounting an electronic device having a plurality of leads on a printed circuit board, by inserting the leads into mount holes of the printed circuit board. Wherein a plurality of extension pins are connected straight to the leads to hold the leads of the electronic device, these extension pins are inserted into the mount holes, while the connection between the extension pins and the leads is maintained, then these extension pins are removed from an opposite side of the printed circuit board, thus guiding and inserting the tips of the leads into the mount holes.
Abstract:
An interposition structure interposed between substrates and capable of guiding the insertion of a connection pin for electrically connecting the substrates to each other, whereby the connection pin can be inserted properly even in cases where the substrates to be connected or other members have a dimensional error caused during production thereof, a positioning error or the like. The interposition structure has an interposition body in which a through hole is formed such that connection pin inlet and outlet portions thereof each have an inner diameter gradually increasing in a direction from the inner part to the corresponding outer open end thereof, and also has a positioning protuberance provided on the underside of the interposition body. The interposition structure is interposed between upper and lower substrates with the positioning protuberance received in a recess formed in the upper surface of the lower substrate, and the connection pin is inserted through a hole in the upper substrate, the through hole, and a hole in the lower substrate.
Abstract:
A coupling structure for a motor coil is provided to easily connect and fix a coil to a printed circuit board by coupling the coil to a connecting pin which is connected to the printed circuit board. A coupling structure electrically couples a coil(130) wounded around a stator(150) of a motor assembly to a circuit pattern(111) of a printed circuit board(110). Plural connecting pins(120) are electrically connected to the circuit pattern of the printed circuit board. The coil is indirectly connected to the circuit pattern through the connecting pins to control current flowing through the coil. The coil is soldered on a protruding portion of the connecting pin.
Abstract:
A printed circuit board assembly and method of assembly is provided for a printed circuit board having a top and bottom surface with at least one edge portion having a rounded surface extending from the top surface to a point below the top surface and at least one electrical contact pad located on the top surface and extending over the edge portion rounded surface to a point below the top surface.
Abstract:
The invention relates to an arrangement comprising an electric and/or electronic module (10) and a circuit carrier (12), wherein at least one electric connecting line (14) of the electric and/or electronic module (10) can be accommodated in a recess (16) of the circuit carrier (12). The arrangement comprises at least one clamping element (18a, 18b, 18c, 18d) which immobilizes the at least one connecting line (14) in the recess (16) once it has been introduced into the recess (16).
Abstract:
There is disclosed a base member for holding, without screws, a printed circuit board having conductive traces and electronic components and which can fit into an electric outlet box. The base member has walls which define a cavity where at least one wall of the cavity has a rib, the top of which functions as a stop for the printed circuit board. A cap having snap features adapted to engage the walls of the cavity restricts removal of the printed circuit board when snapped into position on top of the printed circuit board. The cap conceals the electronics on the printed circuit board and has at least one rib on its bottom surface to apply pressure to the printed circuit board assembly to help hold it in place. An aperture in the cap provides access to a pin header which is electrically connected to the printed circuit board. A screw terminal block is provided to connect the terminals on the pin header to a sensor. The printed circuit board has one edge an open side hour glass shape aperture which provides strain relief for wires from the printed circuit board. Opposite ends of the aperture hold two wires captive and the space between the two wires holds captive a third wire.
Abstract:
A circuit board includes an antenna substrate and a main substrate. The antenna substrate has at least one first linking portion. The main substrate has at least one second linking portion. The first linking portion connects with the second portion so that the antenna substrate assembles with the main substrate. Herein, the antenna is substantially perpendicular to the main substrate.
