A composite inductor includes a block made of resin or rubber having a magnetic material dispersed therein. Spirally wound coils are buried in the block so that the coil axes of the coils are arranged in the same direction. The end portions of the coils are electrically connected to external electrodes provided on two surfaces of the block substantially at a right angle to the axes of the coils.

A connector having a housing with a cavity, a terminal fixed in the housing and a resistance board. The resistance board has an elastic insulating board and a number of conductors which are provided in the insulating board such that each conductor shows on an upper surface and a lower surface of the insulating board. The resistance board is inserted in the cavity of the housing so as to lie on an end portion of a flexible cable. A signal-transmitting conductor of the flexible cable is electrically connected with the terminal via the conductors of the resistance board.
摘要:
A modular jack to be mounted on a circuit board, the modular jack having contactors which will come into contact with a plug and terminals which will be connected with printed wires on the circuit board. The contactors and the terminals are stamped out of a hoop and fixed in a body case of the modular jack. An end of the contactors and an end of the terminals are arranged nearby, and filter elements for eliminating noise are disposed between the nearby ends.
摘要:
A method of manufacturing an inductor includes the step of molding a magnetic material formed by kneading a magnetic material and a resin to form a magnetic material compact body in which the internal conductor is partially exposed from the external surface thereof. Then the surface of the magnetic material compact body is plated to form the external electrodes including a plated metal film and connected to the internal conductor. The surface of the magnetic material compact body is roughened, and then the external electrodes are formed via plating.
摘要:
A connector comprising a housing having a varistor-characteristic resin portion, and signal coupling terminal conductors which penetrate the varistor-characteristic resin portion. The housing itself is made of a varistor-characteristic resin material or the housing is fitted, at its side recess portion, with the varistor-characteristic resin material.
摘要:
A surface mountable connector to be mounted on a printed substrate has a plurality of connector pins projecting from the rear surface to be connected with wiring patterns on the printed substrate through a connector pin holder. The connector pin holder has a plurality of through holes at a pitch equal to that of the connector pins and a plurality of conductive patterns on the outside thereof corresponding to the through holes. The connector pins are inserted into the through holes in the connector holder and electrically connected to the conductive patterns corresponding to the through holes respectively, and the connector pin holder is placed on the wiring patterns on the printed substrate with the conductive patterns on the outer surface connected to the wiring patterns on the surface of the printed substrate by soldering, thereby electrically connecting the tip of each connector pin to a corresponding wiring pattern on the surface of the printed substrate.
摘要:
An inductor is constructed to achieve efficient formation of external electrodes, and exhibits high reliability of connection between the external electrodes and an internal conductor, and desired characteristics. In the method of manufacturing the inductor, a magnetic material formed by kneading a magnetic material and a resin is molded to form a magnetic material compact body in which the internal conductor is partially exposed from the external surface thereof, and then the surface of the magnetic material compact body is plated to form the external electrodes including a plated metal film and connected to the internal conductor. The surface of the magnetic material compact body is roughened, and then the external electrodes are formed via plating.
摘要:
A filter connector comprising a housing made of insulating material, an earth plate fitted to the housing, which earth plate has an engaging portion to be engaged with a circuit board, and a signal transmitting pin fitted to the housing, which pin has a filter element electrically connected with the earth plate. The earth plate is connected directly with a ground conductor on the circuit board, and the engaging portion prevents the connector from separating from the circuit board.
摘要:
A filter connector comprising a housing, connector terminals mounted on the housing, filter elements mounted around the connector terminals, and a support plate for supporting the filter elements as being mounted on the housing. The support plate has pairs of elastic flaps which are formed at the positions corresponding to each of the filter elements, the free end of each flap holds the external surface of each filter element to prevent destruction of the filter elements attributable to the difference in the thermal expansion coefficients of materials.
