Abstract

PURPOSE:To attain electric connection and fixing of lead wires to connector terminals simply even if a connector lag or soldering is not used by inserting the connector terminals into connector terminal holes from the other end sides and squeezing the connector terminals into the conductors of the lead wires. CONSTITUTION:The length of respective connector terminals 12 is set up to a value enabling respective points to reach a stepped part of connector terminal holes 8. A notched groove 13 to embed by the head of each connector terminal 12 is formed on the opening edge of each connector terminal hole 8 on the connector terminal 12 insertion side. When the end parts of the lead wires 11 are to be inserted into the connector terminal holes 8, the end parts are made reach the deep portions of the large diameter parts of the connector terminal holes 8. The connector terminals 12 are pressed into the connector terminal holes 8 embedding the end parts of the lead wires 11 in respective insides from the other end sides and squeezed into the conductors 14 of the lead wires 11.

/ L9J (D) The cartridge connection lead wire (B) is connected to the multiple connector terminal holes provided in the connector OQ.
It has a stepped structure with a smaller diameter on the side and a larger diameter on the sub-insertion side of the connector terminal. Each of the connector terminals (2) has a length such that its tip reaches the stepped part of the connector terminal hole (8), and the length of the connector terminal (2) is such that the tip reaches the stepped part of the connector terminal hole (8).
) A cutout groove (C) is formed on the insertion side opening edge to fit the head flange of the connector terminal @.

Insert the end of the connector into the connector terminal hole (8). At this time,
The end of the lead wire Qη reaches deep into the large diameter part of the connector terminal hole (8). Then, the connector terminal (2) is press-fitted from the other end into the connector terminal hole (8) into which the lead wire α→ has been pushed through, and inserted into the conductor θ of the lead wire θυ. As a result, the lead wire 0υ is electrically connected to the connector terminal @, and the end of the lead wire συ is fixed to the inner surface of the connector terminal hole (8). At this time, in particular, since the connector terminal hole (8) has a stepped structure, the end of the expanded lead wire Oυ is caught at the stepped part, and its fixation is extremely strong. Therefore, the lead wire θ
