(5) The third width W3 is provided between the outer side of the first bending portion 5 and the outer side of the second bending portion 6 of the guiding portion 4, the second width W2 is greater than the first width W1, the first width W1 is greater than the third width W3, so as to ensure that the guiding portion 4 has a better guiding function, so that the elasticity of the insertion portion 3 at the through hole 31 is better, and the circuit board 200 has a larger abutting force to ensure that the insertion portion 3 is stably contacted with the circuit board 200, and the stress portion of the limiting portion 21 in the insertion force direction is located between the outer side of the first bending portion 5 and the outer side of the second bending portion 6 at both sides of the through hole 31, so that the insertion terminal 100 is not easy to shake when being inserted, and the insertion is more stable.
(6) The transition portion 32 abuts against the surface of the circuit board 200 to limit the insertion portion 3, so that the jack terminal 100 is prevented from being inserted backwards continuously, no additional limit structure is required, and corresponding structural design is reduced and processing is convenient.
The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes applying the present specification and the drawings are included in the scope of the present invention.
