[0012] Beneficial effects:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, as the pin gradually enters the hole of the circuit board, the elastic part is squeezed by the hole of the circuit board and contracts toward the center of the pin, reducing the distance between the two sides of the through hole; when the limiting part abuts the circuit board, the elastic part releases the elastic force and fits tightly against the inner wall of the hole of the circuit board, so that the pin is pre-fixed on the circuit board and is not affected by gravity, ensuring the consistency during welding and overcoming the problems mentioned in the background technology, so that the product has the advantages of pre-fixation and easy welding.

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0021] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0022] Reference example Figure 1 , 2A fisheye pin includes a conductive sheet 1, the conductive sheet 1 is provided with a pin 2, and both sides of the pin 2 are provided with an elastic part 21 that can shrink inwards, and the pin 2 is provided with a through hole 22, and is located between the elastic parts 21, which is used to store energy for the elastic part 21. As the pin 2 gradually enters the hole 31 of the circuit board 3, the elastic part 21 is squeezed by the hole 31 of the circuit board 3 and shrinks toward the center of the pin 2, reducing the distance between the two sides of the through hole 22. When the limiting part 15 abuts the circuit board 3, the elastic part 21 releases the elastic force and is tightly attached to the inner wall of the hole 31 of the circuit board 3, so that the pin 2 is pre-fixed on the circuit board 3 and is not affected by gravity, ensuring the consistency during welding;

[0023] It is worth mentioning that the conductive sheet 1 is provided with inclined blocks 11 on both sides. When the conductive sheet 1 is mounted on the base, the inclined blocks 11 are connected and fixed to the base by interference fit.

[0024] It is worth mentioning that the conductive sheet 1 is provided with a first extension plate 12, and is arranged opposite to the pin 2. The first extension plate 12 is in an inclined relationship with the conductive sheet 1. The first extension plate 12 is an extension portion of the conductive sheet 1, and the first extension plate 12 raises the height of the second extension plate 14.

[0025] It is worth mentioning that the first extension plate 12 is extended with a bent portion 13, and the bent portion 13 is extended with a second extension plate 14. The bent portion 13 makes the second extension plate 14 have a certain angle, so as to adapt to the electrodes in the electronic components. The first extension plate 12 and the second extension plate 14 have conductive properties.

[0026] It is worth mentioning that the conductive sheet 1 is provided with a limiting portion 15, and the pin 2 is fixed on the limiting portion 15. The limiting portion 15 raises the distance between the conductive sheet 1 and the circuit board 3 to prevent the solder from soldering the conductive sheet 1 to the copper foil of the hole 31 of the circuit board 3;

[0027] It is worth mentioning that the pin 2 is provided with a pointed end 23 , and the pointed end 23 facilitates the pin 2 to enter the hole 31 of the circuit board 3 .
