[0027] To better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0028] Specific embodiment description section.

[0029] Example 1:

[0030] Reference Figures 1 to 3 The pin assembly of this embodiment is suitable for the pins of an electrical connector. The pin assembly includes a clip-type cassette 1 and a plurality of pins 2.

[0031] The clip-type cassette 1 includes a cassette body 11, which is evenly provided with a plurality of positioning through holes 111; a plurality of pin clamps 112 are evenly provided on the upper and lower sides of the cassette body 11 and are perpendicular to the cassette body 11, and the ends of the pin clamps 112 are provided with V-shaped notches 113, and the bottom of the V-shaped notches 113 is provided with a card slot, wherein the pin clamps 112 on the upper and lower sides of the cassette body 11 are parallel to each other and aligned in pairs.

[0032] The V-shaped notch 113 has a guiding function. When the pin 2 is inserted into the slot, it can be assembled by blind insertion, making the assembly more convenient and simple.

[0033] The positioning through hole 111 provided on the cassette body 11 can facilitate the processing equipment to position and fix the clip-type cassette 1 to ensure that the clip-type cassette 1 is stably installed on the equipment, and facilitate the processing of the pin 2 after the clip-type cassette 1 is transferred or positioned, such as electroplating.

[0034] The middle of each pin 2 is locked in two slots aligned vertically on the clip-type cassette 1, so that multiple pins 2 are arranged in parallel.

[0035] The pin 2 is provided with a contact area 21, a connection area 22 and a welding area 23, which are connected in sequence from top to bottom; the pin 2 is entirely wrapped with a nickel-plated layer, and the contact area 21 is covered with a matte tin-plated layer (such as Figure 1 The soldering area 23 is covered with a gold plating layer or a matte tin plating layer on the nickel plating layer (as shown in the shadow of the upper part of the middle pin 2). Figure 1 (As shown in the shadow below pin 2 in the figure). The nickel plating provides excellent oxidation resistance, preventing pin 2 from oxidizing due to high temperatures during the soldering process, ensuring soldering quality. Furthermore, the nickel plating strengthens the bond between pin 2 and subsequent plating layers, making the gold plating or matte tin plating more secure and less likely to fall off. The nickel plating has a certain hardness, which improves the wear resistance of pin 2 and reduces wear caused by prolonged use. The gold plating or matte tin plating protects the soldering area 23 from oxidation and corrosion, extending the service life of pin 2.

[0036] The top of the contact area 21 is provided with a chamfer, which makes it easier for the contact area 21 of the pin 2 to mate with the connector.

[0037] Pin 2 has a square cross-section, and two opposing sides of the connection area 22 are provided with protrusions 221. Protrusions 221 comprise a downwardly sloping surface intersecting the side surface, a parallel surface parallel to the side surface, and a vertical surface parallel to the side surface. The parallel surface's ends intersect with the sloping surface and the vertical surface, respectively. Protrusions 221 not only facilitate smoother insertion of pin 2 into the connector, but also provide a more secure grip, ensuring a more secure fit between pin 2 and the connector's connector, preventing pin 2 from being dislodged from the connector due to excessive force during mating.

[0038] The pin assembly of this embodiment is formed by inserting the pin 2 into the clip-type cassette 1. The clip-type cassette 1 is used to protect the pin 2, which not only prevents the pin 2 from being deformed during processing and facilitates and quickly inserts the pin 2 into the connector for molding, but also has high installation efficiency and saves time. At the same time, protrusions 221 are provided on both sides of the connection area 22 of the pin 2, which can make the pin 2 fit more firmly with the pin seat of the electrical connector, and prevent the pin 2 from being withdrawn from the pin seat due to excessive force when plugging into the connector.
