A method is provided for firmly connecting a connector terminal to a flat conductor. This is a method for electrically connecting the pierce terminalhaving pierce bladesthat pierce through the flat conductorwith the flat conductorby the pierce blades, in which the connection state is adjusted based on a terminal reaction force R acting on the pierced bladeby a ruptured end surfaceof the flat wiring conductor. The adjustment of the terminal reaction force R is made by adjusting a pressing reaction force F/A generated when the pierce bladepierces through the flat wiring conductor

Method for connecting connector terminal

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. A unit for connecting a pierced terminal () comprises a pierced terminal () which comprises a plurality of blades on a pierced terminal () that are designed to pierce individually through a flat cable () and which is designed to be connected as electrically to such the flat cable () due to each of such the blades on the pierced terminal () that is piercing therethrough; and a back up plate () which comprises an opening for insertion () by which an insertion of any of the blades on the pierced terminal () is allowed that is piercing through the flat cable (), wherein such the opening for insertion () is designed to be contacted to individual corresponding parts of such the blades on the pierced terminal () as not less than two pieces that are facing to each other and that are individually inserted into such the opening for insertion (), respectively.

Electrical connection structure of a connecting terminal

The present invention has an object of providing a connection structure capable of easily connecting an LED component to a flat cable. An LED unitincludes an upper casea pierce terminala lower caseand an intermediate terminalAn LED chipis pressed to the pierce terminalby a convexed springto electrically connect the LED chipto the flat cableConductorsincluded in the flat cableare 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 plateof the pierce terminalpiercing through the conductoris formed of a copper alloy, which is a high strength conductive member having a higher strength than that of the conductorand having conductivity.

Connection structure connecting an LED component

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. When there is not change in first and second mode switching signals within a first predetermined time after a change of first mode switching signal, the main control means sets the first switch means to a non-connection state to set a second state where the supply of power to the power feed line for loads is stopped. After a second predetermined time has passed in the second state, the main control means sets the second switch means to a non-connection state to set a third state where the supply of power to the power feed line for loads is stopped.
