  • Patent number: 8683686
    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.

  • Patent number: 7704094
    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.
