It solves the assembly method of the terminal, the connector and the PCB board without soldering.
[0003] Among the existing numerous fish-eye terminals, the commonly used material is 0.4 - 0.6 mm material. Affected by the material thickness and the fish-eye shape, the elastic arms of the terminals all have a rebound limit. If the connection holes of the PBC board are on the small side, during the insertion process of the terminal, under excessive extrusion of the elastic arms, the elastic arms will have a rebound failure phenomenon, resulting in insufficient insertion force and holding force during assembly, thus affecting the connection between the terminal and the PCB board and causing poor contact. Therefore, a fish-eye terminal with a limiting ability is needed to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fish-eye terminal with a limiting ability to solve the problem that the fish-eye terminal mentioned in the above background technique causes insufficient insertion force and holding force during assembly, thus affecting the connection between the terminal and the PCB board and resulting in poor contact.

A PCB board is sleeved on the outer wall of the elastic part, and a PCB board terminal hole is opened in the inner wall of the PCB board. The elastic part is inserted and installed with the PCB board terminal hole. Limiting blocks are fixedly connected to the lower ends of the two sides of the strength component and the upper ends of the two sides of the terminal transition part.

[0010] Preferably, the reinforcing blocks are distributed in four groups around the outer wall of the terminal strength component, and the reinforcing blocks are in a long strip protruding structure.

[0018] Please refer to Figures 1-4, the present utility model provides a technical solution: a fish-eye terminal with a limiting ability, including a shoulder 1, a terminal strength component 2, a terminal insertion part 3, a terminal insertion portion 4, a PCB board 5, an elastic part 6, a limiting support point 7, a terminal transition part 8, a reinforcement block 9, a PCB board terminal hole 10, a limiting block 11 and a support block 12. The lower end of the shoulder 1 is fixedly connected to the terminal strength component 2, and the lower end of the terminal strength component 2 is fixedly connected to the elastic part 6. The inner wall of the terminal strength component 2 and the inner wall of the terminal insertion portion 4 are transversely supported and connected by the support block 12, so that the inner walls of the terminal strength component 2 and the terminal insertion portion 4 can be strengthened up and down, and the insertion is stable. The thickness range of the terminal strength component 2, the terminal insertion part 3, the terminal insertion portion 4 and the elastic part 6 is 0.4 - 0.8 mm, so that the device covers most application scenarios in the market and has great use value. The elastic part 6 is inserted and installed in a limiting and supporting manner with the PCB board terminal hole 10 through the limiting support point 7, so that the elastic part 6 can be limited in the inner wall through the limiting support point 7 to avoid insufficient insertion force and holding force. The elastic part 6 is installed in a limiting and clamping manner with the PCB board 5 through the limiting block 11, and the limiting block 11 is made of inclined elastic material, so that the elastic part 6 can be clamped and fixed with the PCB board 5 through the limiting block 11, and the installation is stable. The two side edges of the terminal strength component 2 are fixedly connected with the reinforcement block 9. The reinforcement block 9 is distributed in four groups of wrapping positions on the outer wall of the terminal strength component 2, and the reinforcement block 9 is a long and protruding structure, so that the terminal strength component 2 can be assisted and strengthened through the reinforcement block 9, and the structure is more stable. The inner wall of the elastic part 6 is fixedly connected with the limiting support point 7, and the lower end of the elastic part 6 is fixedly connected with the terminal transition part 8. The lower end of the terminal transition part 8 is fixedly connected with the terminal insertion portion 4, and the lower end of the terminal insertion portion 4 is fixedly connected with the terminal insertion part 3. A support block 12 is fixedly connected between the inner walls of the strength component 2 and the terminal insertion portion 4. The outer wall of the elastic part 6 is sleeved with the PCB board 5, and a PCB board terminal hole 10 is opened in the inner wall of the PCB board 5. The elastic part 6 is inserted and installed with the PCB board terminal hole 10. Limiting blocks 11 are fixedly connected to both lower ends of the strength component 2 and both upper ends of the terminal transition part 8.
[0019] Working principle: When using the fish-eye terminal with a limiting ability, first assemble and install the device, then insert the terminal insertion part 3, the terminal insertion portion 4, the elastic part 6 and the terminal transition part 8 into the PCB board terminal hole 10 in the PCB board 5, and then elastically contract through the elastic part 6. When inserting, the lower limiting block 11 will contract inward and insert it into the PCB board terminal hole 10, and when passing through the PCB board terminal hole 10, it will rebound and expand to form a clamping structure through the upper limiting block 11. When the PCB board terminal hole 10 is too small, the elastic part 6 can be further contracted, and the limiting support can be carried out through the limiting support point 7 to avoid insufficient insertion force and holding force. This is the use process of the fish-eye terminal with a limiting ability.
