Abstract: A method is provided for firmly connecting a connector terminal to a flat conductor. This is a method for electrically connecting the pierce terminal 20 having pierce blades 21 that pierce through the flat conductor 102 with the flat conductor 102 by the pierce blades 21, in which the connection state is adjusted based on a terminal reaction force R acting on the pierced blade 21a by a ruptured end surface 102a of the flat wiring conductor 102. The adjustment of the terminal reaction force R is made by adjusting a pressing reaction force F/A generated when the pierce blade 21 pierces through the flat wiring conductor 102.

Abstract: An objective is to provide a connection structure of a connecting terminal by which it becomes able to perform a connection of any of pieces for piercing as assuredly without being bended that is piercing through an electrically conductive flat square body, and to provide a method of connecting such the terminal.

Abstract: The present invention has an object of providing a connection structure capable of easily connecting an LED component to a flat cable. An LED unit 1 includes an upper case 7, a pierce terminal 6, a lower case 9 and an intermediate terminal 5. An LED chip 3 is pressed to the pierce terminal 6 by a convexed spring 51 to electrically connect the LED chip 3 to the flat cable 100. Conductors 101 included in the flat cable 100 are formed of phosphor bronze formed of tin (Sn), phosphorus (P), copper (Cu) and unavoidable impurities and having a tensile strength of 480 to 550 MPa, whereas a pierce plate 63 of the pierce terminal 6 piercing through the conductor 101 is formed of a copper alloy, which is a high strength conductive member having a higher strength than that of the conductor 101 and having conductivity.

Abstract: An LED lighting device provided with a flat circuit body where LEDs are mounted in a lamp room that is constructed from a lamp body and a lens installed on a front opening of the lamp body, and with a reflector structure body for reflecting light that is emitted from the LEDs. Opening are formed in a wall section of the reflector structure body, and the LEDs of the flat circuit body are installed in the openings. As a result, the flat circuit body supported by the reflector structure body.

Abstract: A three-dimensional, electronic components mounted wiring body comprises a flat wiring body, on which a plurality of electronic components is mounted, and which is preformed with bends to be configured into a three-dimensional structured flat wiring body which fits the shape of a base structure on which the flat wiring body is to be mounted. An electronic components mounting structure is provided by mounting the three-dimensional, electronic components mounted wiring body on the three-dimensional base structure which is assembled from base members and their joining members. Connectors having piercing members are used to electrically and mechanically connect the electronic components to the flat wiring body.

Abstract: An electronic components mounted wiring body (10) comprises a flat wiring body (2) on which a plurality of electronic components (20) is mounted, and a plurality of base members (31) on which the flat wiring body (2) is mounted. The flat wiring body (2) has arrangement direction changing folds (9), each of which is designed to change an arrangement direction of the electronic components (20) of the flat wiring body (2). Each base member (31) has an arrangement direction changing member (37) which is designed to fix the arrangement direction changing fold (9). The base members (31) are joined using joining members (32) so that the electronic components mounted wiring body (10) is configured into a three-dimensional shaped electronic components mounting structure (1).

Abstract: An optical signal transmission device includes an emitter, a receiver, and a reflector. The emitter includes a light-emitting element having an optical axis thereof deviating from a first propagation path toward a second propagation path such that a ratio of an incident intensity, at the receiver, of a second optical signal propagating along the second propagation path to an incident intensity, at the receiver, of a first optical signal propagating along the first propagation path is equal to or higher than a predetermined value at or above which a faulty optical-signal transmission is not caused, whereby the second optical signal of a required level enters into the receiver for reliable and stable optical signal transmission.

Abstract: A vehicular use power distribution apparatus includes a battery mounted in a vehicle; a main control means connected directly to the battery; a first switch means connected to the battery; a power feed line for loads connected to the first switch means and supplying power to loads mounted in the vehicle; a second switch means connected to the battery; a power feed line for control means connected to the second switch means and controlling the loads; and a sub control means connected to the power feed line for control means. In a first state, the main control means sets the first switch means and the second switch means to a connection state so as to supply power from the battery to the power feed line for loads and the power feed line for control means.
