Abstract:
The circuit-board connecting terminal (1) includes a small-width portion (7) to be inserted into a through hole (22) formed in a circuit board (12), a pair of taper portions (8) respectively to be abutted against an open end (23) of the through hole (22), and a large-width portion (5) formed so as to be continuous with the taper portions (8), while the small-width portion (7) can be connected to the inside of the through hole (22) by soldering. In the circuit-board connecting terminal (1), the taper portions (8) have a steep inclination angle, and are located at the open end (23) of the through hole (22), so as not to advance almost into the through hole (22).
Abstract:
Electromagnetic shielding devices are provided with walls having a pair of opposing, generally parallel side faces that terminate at a tapered end portion. Each tapered end portion is configured to be surface mounted to a respective conductive portion (e.g., mounting pad) of an electronic substrate via a pair of solder fillets. The tapered end portion of each wall includes a pair of elongate end faces symmetrical about a plane that is generally parallel to, and equidistant between, the wall side faces. The end faces define a pair of elongated cavities with respect to a PCB that are configured to receive the solder fillets.
Abstract:
An RF connector includes a conductive pin for carrying an RF signal. The conductive pin has a first longitudinal end that serves to interface with a male RF connector to receive the RF signal. The pin also includes a second longitudinal end for connecting with a printed circuit board (PCB). The second longitudinal end may be tapered, and the pin may have a groove formed above the tapered end. A housing encircles the conductive pin. The housing is shaped and sized to accept the male RF connector. A grounding element may be positioned on the bottom of the housing. The grounding element is to contact the PCB when the connector is connected to the PCB. The grounding element may be ring-shaped and soldered to the housing or epoxied to the housing.
Abstract:
The electronic device of the present invention is an electronic device configured by soldering a terminal member to a printed circuit board, the terminal member comprising a top surface into which a screw is threaded and a side surface at the end connected to the top surface, the side surface having convex parts fitted into through-holes in the printed circuit board; wherein the terminal member has at least two convex parts in the end edge on the printed circuit board side of the side surface, an electro conductive pattern is provided on the printed circuit board facing the end edge between the convex parts, solder is filled into a gap between the end edge and the electro conductive pattern, when the two convex parts are inserted into the through-holes provided to the electro conductive pattern, and electrical continuity is established between the end edge and the electro conductive pattern.
Abstract:
Welded assembly comprising an element (2) made of a thermally conducting material and a support (1), the element (2) comprising a massive part (5) protruding from which there are at least one fixing lug (6) comprising, on the one hand, a stepped intermediate portion (6.1) forming a spacer piece and resting against a first face (1.1) of the support (1), on either side of a hole (4) made in the support (1) and, on the other hand, a free end portion (6.2) projecting axially from the intermediate portion (6.1) to extend into the hole (4) and be welded to a second face (1.2) of the support (1) which is the opposite face to the first face (1.1). The intermediate portion (6.1) has an exterior shape that defines a narrowing of cross section.
Abstract:
In a module, press-fit connection using a pin terminal (1) including a connection part (2) separated into two parts and a flat plane (2a) parallel to the lengthwise direction in the separation part and perpendicular to the separation direction of the pin terminal (1) is performed. A through-hole of a board is structured so that (1) an inner diameter of the through-hole at a middle part in the thickness direction of the board is smaller than that at obverse and reverse surfaces of the board (4) and (2) the length of the middle part of the through-hole connected to the pin terminal (1) is shorter than the length of the flat plane (2a) of the pin terminal (1).

PROBLEM TO BE SOLVED: To significantly improve the efficiency of installing a tuner module onto a main substrate.SOLUTION: During installation of a tuner module body encompassing a tuner substrate onto a main circuit board body 2, a tip provided with a taper 21s of a first leg 21 protruding from the tuner module body is inserted into a first hole 61 formed on the main circuit board body 2. Next, a tip provided with a taper 22s of a second leg 22 being shorter than the first leg 21 and protruding from the tuner module body is inserted into a second hole 62 formed on the main circuit board body 2. Then, a signal terminal 11 being shorter than the second leg 22 and protruding from the tuner substrate is inserted into a third hole 64 formed on the main circuit board body 2.
