Description

Technical Field

[0001] This application relates to the field of terminals of connectors, and particularly to a circular terminal. Background Art

[0002] In the field of connections of electronic devices, as a key component for transmitting electrical signals, the performance stability and reliability of connectors are crucial. Traditional connector terminal designs often have some problems, especially in terms of the behavior during the process of the outer diameter of the terminal and inserting it into the plastic hole.

[0003] Generally, the outer diameter of traditional connector terminals is in a parallel state. This design is prone to rotational looseness due to the lack of sufficient interference when inserting into the plastic hole. When the terminal rotates in the plastic hole, the contact with the plastic hole wall becomes unstable, resulting in abnormalities during the subsequent riveting process. This rotational looseness not only affects the electrical performance of the connector but also may cause a decrease in the mechanical strength of the connector, thus affecting the reliability and service life of the entire electronic device. Summary of the Utility Model

[0004] The purpose of this application is to provide a circular terminal, aiming to effectively prevent the rotational looseness of the terminal when inserting it into the plastic hole by changing the diameter gradient characteristic of the main body part of the terminal, thereby eliminating the abnormal riveting caused thereby.

[0005] To achieve the above purpose, this application provides the following technical solutions:

[0006] A circular terminal includes a main body part and a tail. The tail extends backward from the rear end of the main body part. The main body part is in a hollow cylindrical shape, and the diameter of the main body part gradually increases from the front end of the main body part along the axis direction to the tail.

[0007] In one embodiment, the diameter of the front end of the main body part is 0.97 mm, and the diameter near the tail end is 1.09 mm.

[0008] In one embodiment, a clearance hole is provided on the main body part.

[0009] In one embodiment, barbs are provided on both sides of the tail.

[0010] In one embodiment, a slot is provided at the junction of the tail and the main body part.

[0011] In one embodiment, a glue-blocking plate is provided inside the tail.

[0012] In one embodiment, a welding part extends backward from the tail.

[0013] The beneficial effects of this application are:

[0014] First, the circular terminal body of the present application adopts a hollow cylindrical design, and its diameter gradually increases from the front end to the tail end. This unique gradient design enables the terminal to gradually interfere with the plastic hole wall when pre-inserted into the plastic hole, effectively preventing the terminal from rotating and loosening, and thus avoiding the abnormal riveting problems caused thereby. In the traditional connector terminal design, rotation and loosening often lead to poor riveting, which in turn affects the electrical performance and mechanical strength of the connector. The circular terminal design of the present application fundamentally solves this problem, thereby ensuring the stability and reliability of the connector during long-term use.

[0023] The terms used in the embodiments part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below in conjunction with the drawings.

[0024] Embodiment 1

[0025] As Figure 1As shown, this embodiment provides a circular terminal. The terminal is installed in the plastic hole of the connector body 8, and its structure includes a main body part 1 and a tail part 2. The tail part 2 extends backward from the rear end of the main body part 1 to form an integral structure. The main body part 1 is in the shape of a hollow cylinder, and its diameter gradually increases from the front end of the main body part 1 along the axis X direction to the tail part 2. This design enables the terminal to gradually interfere with the plastic hole wall when inserted into the plastic hole of the connector, effectively preventing the terminal from rotating and loosening.

[0026] As Figure 5 shown, when half of the terminal is inserted into the plastic hole of the connector, there is still a gap between the terminal and the plastic hole wall, which is convenient for the insertion of the terminal. As Figure 4 shown, only when the terminal is completely inserted in place, the main body part of the terminal interferes with the plastic hole wall to prevent the terminal from rotating and loosening.

[0027] As Figure 2 shown, in a specific implementation, the diameter R1 at the front end of the main body part 1 is 0.97 mm, and the diameter R2 near the tail end is 1.09 mm. This design of gradual change in diameter not only ensures that the terminal can be smoothly inserted into the plastic hole but also can generate sufficient interference after insertion to prevent the terminal from rotating.

[0028] Embodiment Two

[0029] As Figure 1 shown, in this embodiment, a clearance hole 3 is provided on the main body part 1. The design of the clearance hole 3 can serve as a drainage channel during the electroplating process, facilitating the rapid discharge of the electroplating solution, thereby accelerating the drying process and improving production efficiency.

[0030] Embodiment Three

[0031] As Figure 1 shown, in this embodiment, barbs 4 are provided on both sides of the tail part 2. The design of the barbs 4 enhances the clamping force between the terminal and the plastic hole, effectively preventing the terminal from falling off or rotating after insertion. In addition, the barbs 4 can also increase the pulling strength of the terminal to a certain extent and improve the reliability of the connection.

[0032] Embodiment Four

[0033] As Figure 1 shown, in this embodiment, a slot 5 is provided at the junction of the tail part 2 and the main body part 1. The design of the slot 5 also helps with drainage and drying during the electroplating process. During electroplating, the electroplating solution can more easily pass through the slot 5, reducing residue, thereby accelerating the drying process and ensuring that the electroplating layer on the surface of the terminal is uniform and firm.

[0034] Embodiment Five

[0035] As Figure 4As shown, a rubber baffle 6 is provided inside the tail part 2 of this embodiment. The design of the rubber baffle 6 can prevent the plastic material from flowing into the internal space of the main body part 1 during the injection molding process, thereby keeping the main body part 1 clean and tidy. This is crucial for subsequent electrical connections because a clean main body part 1 can ensure the connection quality and reduce the production of defective products.

[0036] Embodiment Six

[0037] As Figure 1 shown, a welding part 7 extends backward from the tail part 2 of this embodiment. The setting of the welding part 7 enables the terminal to be conveniently welded to other electronic components, thereby expanding the usage range and application scenarios of the terminal. The shape and size of the welding part 7 can be adjusted according to actual needs to meet the requirements of different welding processes.
