Description

Technical Field

[0001] This utility model relates to the field of hardware components, and in particular to a light touch spring that can be applied to automated plug-in components. Background Technology

[0002] Touch springs on circuit boards often lack sufficient strength due to their height, making them prone to wobbling. This can lead to slow response times after touch, resulting in a poor user experience or quality issues. Designing a structure that enhances strength, improves touch response speed, and increases reliability can effectively improve product quality. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an enhanced stability tactile spring, comprising a spring bottom fixing part, with a spring body fixed to the upper end of the spring bottom fixing part. The spring body is characterized by having a lower arc-shaped bottom, with a first elastic part connected to the upper end of the arc-shaped bottom. A dense coil portion is provided at the upper end of the first elastic part, and a second elastic part is provided at the upper end of the dense coil portion. A wide coil portion is provided at the upper end of the second elastic part. The spring body is integrally formed.

[0004] Furthermore, the arc-shaped bottom is small in the middle and large at both ends, and the spring coils are tightly fitted together. The bottom ring of the arc-shaped bottom is fixed to the upper end of the spring bottom fixing part with fasteners. There are more than three fasteners evenly distributed on the spring bottom fixing part, and the fasteners and the spring bottom fixing part are integrally formed.

[0005] Furthermore, the first elastic part and the second elastic part are composed of multiple spaced spring coils, the diameter of which is the same as the diameter of the upper end of the arc-shaped bottom.

[0006] Furthermore, the area of ​​the wide ring portion is larger than the area of ​​the second elastic portion, and the wide ring portion and the second elastic portion are connected by a tapered structure, wherein the large end of the tapered structure is connected to the wide ring portion.

[0007] Furthermore, the two sides of the spring base fixing part extend downward to form two extension legs, which merge into one after extension to form the sticker part.

[0008] By utilizing the above-mentioned utility model solution, the effectiveness of the arc-shaped bottom of the spring in improving strength can be brought into play. At the same time, the dense coil portion prevents wobbling and deformation caused by excessive length when the first elastic portion and the second elastic portion are connected, thus effectively improving strength.

[0011] Figure 2 A three-dimensional schematic diagram of the product of this utility model, focusing on the connecting strip, is shown. Detailed Implementation

[0012] according to Figures 1-2 As shown in the embodiment of this utility model, an enhanced stability tactile spring is provided, which includes a spring bottom fixing part 7, a spring body fixed at the upper end of the spring bottom fixing part 7, an arc-shaped bottom 6 at the lower end of the spring body, a first elastic part 4 connected to the upper end 5 of the arc-shaped bottom 6, a dense coil part 3 provided at the upper end of the first elastic part 4, a second elastic part 2 provided at the upper end of the dense coil part 3, and a wide coil part 1 provided at the upper end of the second elastic part 2. The spring body is an integrally molded structure.

[0013] In this embodiment, the arc-shaped bottom 6 is small in the middle and large at both ends, and the spring coils are tightly attached to each other. The bottom ring of the arc-shaped bottom 6 is fixed to the upper end of the spring bottom fixing part 7 with fasteners 71. There are three or more fasteners 71 evenly distributed on the spring bottom fixing part 7, and the fasteners 71 and the spring bottom fixing part 7 are integrally formed.

[0014] In this embodiment, the first elastic part 4 and the second elastic part 2 are composed of multiple spaced spring coils, and their coil diameter is the same as the upper end 5 of the arc-shaped bottom 6.

[0015] In this embodiment, the area of ​​the wide ring portion 1 is larger than the area of ​​the second elastic portion 2, and the wide ring portion 1 and the second elastic portion 2 are connected by a conical structure. The large end of the conical structure is connected to the wide ring portion. This conical structure can help improve its strength and prevent shaking or wobbling when touched.

[0016] In this embodiment, the two sides of the spring bottom fixing part 7 extend downward to form two extension legs 72. The two extension legs 72 merge into one to form a sticker part 73. When a large number of springs are pasted onto the paper tape 8, the paper tape 8 is rolled into a disc. By rotating the disc, the springs on the disc can be released slowly and easily. This can be used for automatic insertion in an automated insertion production line.
