[0007] Since the base material of the flat conductor is made of resin, and the terminal is made of metal, it is very thin, so if the flat conductor contacts the connection part of the terminal, it is easy to be damaged by the connection part of the terminal
Although the base material of the flat conductor is made of resin, there is a metal connection part as a circuit line at the front end. If it is damaged, resin powder and metal powder will be generated due to the grinding of the front end of the flat conductor, which will cause contact failure and short circuit. s reason

Embodiment Construction
[0026] Hereinafter, embodiments of the present invention will be described based on the drawings.
[0027] figure 1 It is a perspective view showing an electrical connector for a flat conductor (hereinafter referred to as a connector) 1 and a flat conductor F connected thereto according to the present embodiment, (A) showing before the flat conductor is connected to the connector 1, and (B) showing the connection after.
[0028] The flat conductor F has, on the upper surface of the front end portion of the flat conductor F, a connection portion F1 which is introduced into the connector 1 and connected to a terminal of the connector. In this embodiment, circuit lines extending along the longitudinal direction of the flat conductor (only the front end portion where the connection portion F1 is formed is shown in the figure, and the rear portion is omitted) are arranged in a number corresponding to the number of the above-mentioned terminals. F2, the circuit line F2 has a circu...

The present invention provides an electrical connector for flat conductors that can be introduced without damaging the flat conductors. The casing (30) has a connecting portion (F1) which is formed to receive the flat conductor (F) toward the front at the rear portion of the peripheral wall formed by the upper wall (35), the lower wall (36) and the side walls (37) on both sides. The lead-in wall portion (39) of the receiving portion (38) of the terminal, the contact portion of the terminal that is in contact with the connecting portion (F1) is located in the receiving portion, and the rear end of the upper wall of the lead-in wall portion is within the width direction range of the flat conductor. The rear end of the lower wall is located forward, and the upper surface of the lower wall has an exposed surface (43) exposed upward at a position rearward of the rear end of the upper wall (35). 13A-1) The area other than the arrangement area is located above the upper edge of the connection portion, and the front end edge of the flat conductor can abut against the exposed surface during the process of introducing the flat conductor toward the receiving portion (38).
Description
technical field [0001] The present invention relates to an electrical connector for flat conductors. Background technique [0002] Electrical connectors for flat conductors are widely used as connectors mounted on circuit boards. The electrical connectors for flat conductors have a contact connection with a connection portion provided on the front end side of a flat conductor such as FPC in the longitudinal direction. A contact portion, and a plurality of terminals of the connection portion used to connect with the circuit board; and a housing for arranging and holding the above-mentioned terminals in the width direction of the connector, the housing is composed of an upper wall, a lower wall, and two sides. The rear portion of the peripheral wall formed by the side wall has an introduction wall portion facing forward to form a receiving portion for receiving the connection portion of the flat conductor, and the contact portion of the terminal in contact with the connection ...
