An arm, and a support arm installed between the first and second contact arms, the soldering arm, and the interlocking arm.

  After the interlocking arm is assembled to the connector, one end thereof is driven by the pressure contact part on the connector, and the first contact arm is interlocked and moved to the second contact arm by a seesaw method. Thereby, the clearance gap between a 1st contact arm and a 2nd contact arm shrinks, and a flexible substrate is clamped.

As for the assembly of the insulation case and terminal of the conventional connector, by installing an interference body in the gap between the first contact arm and the second contact arm, it causes interference with the insulation case, and correspondingly couples together to loosen and fall off The purpose of prevention is achieved.
However, as the design requirements become thinner, the conventional assembly method of the insulating case and the terminal of the connector cannot meet the assembly requirements for the thinner design.
This is because the interference body installed in the above-described conventional gap needs to consider the entire thickness of the interference body and the flexible substrate to be sandwiched.

In assembling the thin connector, it is possible to adopt an integrated molding (Insert Molding) so that the terminals to be assembled can be fixed together when molding the insulating case.
However, this method is expensive and has a limit in the manufacturing process.
Improving the structure of the terminals used in the flexible board connector to meet the assembly requirements for thinning is an issue that the industry is focusing on solving and overcoming.
The present invention has been made in view of the above-described drawbacks of conventional flexible board connectors.

  The problem to be solved by the present invention is to fix the connector to the circuit board by the soldering arm of the terminal, and to assemble the terminal in a thin insulating case for the purpose of installing the positioning aid. It is an object of the present invention to provide a flexible board connector that can realize a firm transmission of an electric signal without fear of dropping off.

In order to solve the above problems, the present invention provides the following flexible board connector.

Y axis direction When the terminal is assembled by the above-described structure, a first stopper is installed in the vicinity of one side of the corresponding first contact arm and the interlocking arm, or the second contact arm and the soldering arm. The first stopper advances toward the engagement control wall, so that after the terminal is assembled, the first stopper is positioned on the engagement control wall side, and in the opposite direction, the first stopper is not loosened and dropped out in the terminal assembly direction. One stopper is installed on one side of the first contact arm and the interlocking arm, and a protrusion is integrally formed from the first contact arm. The terminal is opposed to the first stopper and a second stopper is installed on the terminal. The second stopper provides a solid assembling effect, and the second contact arm integrally forms a reverse hook so that the terminal is assembled in the opposite direction after the terminal is assembled to the receiving installation tank.
