Flat spring

Abstract

A flat spring includes two connecting ends and multiple spring strips. The two connecting ends are spaced apart and parallel to each other. The two ends of each spring strip are connected to the two connecting ends. The spring strips are bent, each having a middle section and two inclined sections. The middle section is located in the middle of the spring strip, and one end of each of the two inclined sections is connected to both ends of the middle section, extending inclinedly towards the same side of the spring strip. The other ends of each inclined section are connected to the two connecting ends. Each bend of the spring strip forms two contact points. A slot is formed between each pair of adjacent spring strips, corresponding to the bend of the spring strip. This increases the length of the spring strips and slots, resulting in more uniform stress and better strain resistance. Furthermore, the flat spring can be further bent into a cylindrical shape to form a crown spring.

Description

Technical Field

[0001] This invention relates to a crown spring and a flat spring, and more particularly to a crown spring and a flat spring that can be disposed in a connector for achieving an electrical connection with a mating connector. Prior Technology

[0002] Crown springs have been widely used in the mating connection of male and female terminals of electrical connectors to reduce the machining accuracy requirements of male and female terminals. This can avoid the phenomenon that the male and female terminals are not securely fixed or difficult to insert or remove due to the tolerance mating connection.

[0003] Existing crown springs all have multiple spring bars, which are generally straight and spaced apart. These spring bars are bent inward to form contact points, and a slot is formed between each pair of adjacent spring bars. However, the straight spring bars are relatively short, resulting in uneven stress distribution, poor elasticity, and good strain resistance, thus leading to poor electrical connection. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a flat spring and a crown spring that are more uniform in force distribution, have better elasticity and strain resistance, and can achieve better electrical connection effect, in order to overcome the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a crown spring, which has a spring body in the form of a flat plate. The spring body includes: two connecting ends, which extend along a longitudinal direction to form elongated strips, and the two connecting ends are spaced apart and parallel to each other; and a plurality of spring strips, the two ends of which are respectively connected to the two connecting ends, and the spring strips are spaced apart. The spring strips are bent, each spring strip having a middle section and two inclined sections. The middle section is located in the middle position of the spring strip. One end of each of the two inclined sections of each spring strip is respectively connected to the two ends of the middle section, and the two inclined sections of each spring strip extend inclinedly towards the same side of the spring strip along the longitudinal direction. The other end of each of the two inclined sections of each spring strip is respectively connected to the two connecting ends. Each spring strip is bent to form two contact points, and the two contact points of each spring strip are bent away from the spring body to form protrusions. A slot is formed between each pair of adjacent spring strips. The spring body is bent into a cylindrical shape.

[0006] Preferably, the two inclined segments of each spring are arranged in a mirror-symmetrical manner on both sides of the middle segment.

In addition, the term "or" used herein should, as appropriate, include any combination of any one or more of the associated listed items.

[0021] [First Embodiment]

[0022] Please refer to Figures 1 to 3. This invention provides a flat spring made of a highly conductive metal material such as copper. It has a spring body 100, which is a flat plate, and may be rectangular, but is not limited thereto. The spring body 100 includes two connecting ends 1 and a plurality of spring strips 2. The two connecting ends 1 extend along a longitudinal direction A to form elongated strips, and are spaced apart and parallel to each other. In this embodiment, the side of the two connecting ends 1 that is furthest from each other may be straight, but is not limited thereto.

[0023] The two ends of each spring strip 2 are respectively connected to two connecting ends 1. The spring strips 2 are spaced apart. Preferably, each spring strip 2 can be a long strip of equal width. The spring strips 2 are bent, that is, viewed from the front of the spring body 100 (as shown in Figure 2), the spring strips 2 are bent in a shape similar to ">". Specifically, each spring strip 2 has a middle section 21 and two inclined sections 22. The middle section 21 is located in the middle of the spring strip 2. One end of each of the two inclined sections 22 is connected to both ends of the middle section 21, and the two inclined sections 22 extend inclinedly along the longitudinal direction A toward the same side of the spring strip 2. The other ends of the two inclined sections 22 are respectively connected to the two connecting ends 1. Preferably, the two inclined sections 22 of each spring strip 2 are mirror-symmetrically arranged on both sides of the middle section 21, so that the force is more evenly distributed.

[0024] Each spring strip 2 is bent to form two contact points 23. The two contact points 23 of each spring strip 2 are bent in a direction away from the spring body 100 to form a protrusion (as shown in Figure 3). The contact points 23 can be in the shape of a convex arc, etc. The two contact points 23 of each spring strip 2 can be located on two inclined segments 22 respectively. Preferably, the other end of the two inclined segments 22 of each spring strip 2 forms a connecting segment 24, which can be connected to the connecting end 1. Preferably, the connecting segments 24 of these spring strips 2 are perpendicular to the longitudinal direction A (as shown in Figure 2). The connecting segment 24 can be used to connect the spring strip 2 and the connecting end 1. The length of the connecting segment 24 can also be changed to correspond to the length of the spring strip 2 and the slope of the inclined segment 22.

[0025] A slot 25 is formed between each pair of adjacent spring strips 2. These slots 25 are bent in shape corresponding to the spring strips 2, that is, when viewed from the front of the spring body 100 (as shown in Figure 2), these slots 25 are bent in a shape similar to ">". Preferably, each slot 25 can be a long strip groove of equal width. The width W1 of the spring strip 2 is greater than the width W2 of the slot 25. A larger width W1 of the spring strip 2 can provide better elastic force and achieve better contact effect.

[0026] As shown in Figure 4, two flat springs can be arranged opposite each other and fixed to a base 5 for installation in the connector, with the two flat springs spaced apart. Thus, the contact points 23 of these springs 2 can contact the terminals of the mating connector, enabling an electrical connection between the connector and the mating connector. The application of the flat springs in this invention is not limited.

[0027] [Second Embodiment]

[0028] Please refer to Figures 5 and 6. This embodiment provides a crown spring, which has a spring body 100. The spring body 100 is a flat plate. The spring body 100 includes two connecting ends 1 and a plurality of spring strips 2. The two connecting ends 1 extend along a longitudinal direction A to form a strip shape. The two connecting ends 1 are spaced apart and parallel to each other. The two ends of each spring strip 2 are respectively connected to two connecting ends 1. The spring strips 2 are spaced apart and are bent. Each spring strip 2 has a middle section 21 and two inclined sections 22. The middle section 21 is located in the middle of the spring strip 2. One end of each of the two inclined sections 22 of each spring strip 2 is connected to the two ends of the middle section 21. The two inclined sections 22 of each spring strip 2 extend inclinedly along the longitudinal direction A toward the same side of the spring strip 2. The other end of each of the two inclined sections 22 of each spring strip 2 is connected to the two connecting ends 1. Each spring strip 2 is bent to form two contact points 23. The two contact points 23 of each spring strip 2 are bent away from the spring body 100 to form a protrusion. A slot 25 is formed between each pair of adjacent spring strips 2. The spring body 100 of this embodiment is generally the same as that of the first embodiment described above. The difference is that the spring body 100 of this embodiment is further bent into a cylindrical shape to form a crown spring. The crown spring is a hollow cylinder that can be inserted into a male terminal.

[0029] As shown in Figure 7, the crown spring can be disposed in a female terminal 6 so that it can be disposed in the connector. Thus, the contact points 23 of these spring strips 2 can contact the terminals of the mating connector, so that the connector and the mating connector can achieve an electrical connection.

[0030] [Third Embodiment]

[0031] Please refer to Figures 8 to 10. The spring body of this embodiment includes two connecting ends 1 and a plurality of spring strips 2. The two ends of the spring strips 2 are respectively connected to the two connecting ends 1. The spring strips 2 are arranged at intervals and are bent. Each spring strip 2 has a middle section 21 and two inclined sections 22. The middle section 21 is located in the middle position of the spring strip 2. One end of the two inclined sections 22 of each spring strip 2 is respectively connected to the two ends of the middle section 21. The two inclined sections 22 of each spring strip 2 extend inclinedly towards the same side of the spring strip 2 along the longitudinal direction A. The other end of the two inclined sections 22 of each spring strip 2 is respectively connected to the two connecting ends 1. A slot 25 is formed between each pair of adjacent spring strips 2.

[0032] The difference between this embodiment and the first embodiment described above is that, in this embodiment, the middle section 21 of each spring strip 2 is straight when viewed from the front of the spring body 100 (as shown in Figure 9). Each spring strip 2 forms a contact point 23, and the contact point 23 of each spring strip 2 forms a protruding straight surface facing away from the spring body 100 (as shown in Figure 10). The contact point 23 of each spring strip 2 is located on the middle section 21. The straight surface design in this embodiment can provide better contact and current conduction. Similarly, the flat spring can also be bent into a cylindrical shape to make a crown spring.
