The annular groove is formed at the position close to the opening of the contact pin jack.

The periphery of the middle part of the jack component is provided with an annular barb, the barb and the jack component are of an integrally formed structure, the interference connection firmness of the jack component and the jack insulator is guaranteed, and the barb is set to be 1-2 rings.

The jack insulator is of a plastic mould plastic-compression integrated structure.

Use the utility model discloses a beneficial effect is: the contact of the original foreign FFC flat cable and the connecting part of the jack component is improved, and the transverse groove welding is adopted to replace the piercing crimping, so that on one hand, the transmission of electrical signals is ensured, on the other hand, the contact performance is improved, and the contact resistance and the vibration stability are mainly reflected. The cost investment of a square needle and hole stamping die can be effectively reduced by changing the contact form, about 50% of the cost investment of the die can be saved, and the contact resistance is improved by nearly 6 times compared with that of a square contact element.
