An electrical connection structure including: a first terminal attached to an edge portion of a circuit board, and composed of a first nipping portion, a connecting portion, a second nipping portion and a leaf spring portion each formed integrally in order as a single member, wherein the connecting portion exists along a side face of the edge portion, the first and second nipping portion and the connecting portion hold the edge portion therebetween and the leaf spring portion extends from an opposite side to the side of the connecting portion of the second nipping portion so that an interior angle formed by the second nipping portion and the leaf spring portion to be an acute; and a second terminal to be electrically connected to the leaf spring portion, wherein the second terminal is pressed to the leaf spring portion into a direction of widening the interior angle.

Electrical connection structure and antenna apparatus

Disclosed is a cabinet of an electrical apparatus including: a base; a cover to cover over the base; a gasket placed on a top face of the base and nipped between a bottom edge section of the cover and the base; a fastening section to penetrate through the base from a bottom face to the top face of the base to connect to an inner face of the cover and to tighten so that the base is pulled to a cover side; a seal integrally formed with the gasket to surround on the top face of the base a through hole which the fastening section penetrates; and a hood provided on an inner face of the cover so as to surround a connecting portion of the fastening section and the cover, and the hood being pressed against the seal.

Cabinet of electrical apparatus and antenna apparatus

Disclosed is a circuit substrate supporting structure including: a base; a cover to cover over the base; a circuit substrate accommodated in the cover in a state standing on the base; a projecting section provided on the circuit substrate in a state projecting from a bottom edge section of the circuit substrate and placed on the base; an elastic piece placed on the projecting section; and a pressurizing section convexly provided on an inner wall of the cover above the projecting section to be pressed against the projecting section from above the elastic piece.

Circuit substrate supporting structure and antenna apparatus

A hybrid antenna unit includes a circuit board having top and bottom surfaces, a planer antenna element which is mounted on the top surface of the circuit board and which receives first and second radio waves, an antenna base and a top cover that cover the circuit board and the planer antenna element. A bar antenna element stands on the top cover in a slanting position. A processing unit is mounted on the bottom surface of the circuit board and is connected to the planer antenna element. The processing unit processes the first and the second radio waves. A shielding case is mounted on the bottom surface of the circuit board and shields the processing unit. A booster circuit is mounted on the circuit board and is for use in the bar antenna element.

Hybrid antenna unit

A circuit board has a first face and a second face opposite to the first face. An antenna element is mounted on the first face. A shield cover is attached to the second face. The shield cover includes a polygonal base portion, a first wall provided on a first side of the polygonal base portion, a second wall provided on a second side of the polygonal base portion, a third wall provided on a corner defined by the first side and the second side, and disposed between the first wall and the second wall, a first extending portion extended from the first wall so as to overlap with the third wall, and a second extending portion extended from the second wall so as to overlap with the third wall. The shield cover is soldered on the second face.

Antenna device and shield cover thereof

A protector-equipped antenna unit has an antenna body including an antenna case, a cable derived from the antenna case to the outside, and a protector having a shape corresponding to an outside shape of the antenna body and of the cable. Inasmuch as the protector-equipped antenna has the protector having the shape corresponding to the outside shape of the antenna body and of the cable, it is possible to use an already-existing antenna unit as the antenna body.

Protector-equipped antenna unit using an already-existing antenna unit as an antenna body

A protector-equipped antenna unit has an antenna body including an antenna case, a cable derived from the antenna case to the outside, and a protector for protecting the antenna body and the cable. The protector has drain holes. The protector has a cable protecting portion having a hook portion for fixing the cable.

Protector-equipped antenna unit with drain structure

An antenna device comprises a coaxial cable that has a central conductor and an outer conductor and is folded into an L-shape at an end portion. An L-shaped first-conductor-portion is electrically connected to the central conductor at the end portion of the coaxial cable. An L-shaped second-conductor-portion is electrically connected to the outer conductor at the end portion of the coaxial cable and is disposed along an outer circumferential face of the coaxial cable. The first and second conductor portions as a whole are formed into an approximate U-shape.
