Technical Field
[0001] This application relates to the technical field of electrical connections, and particularly to a micro double elastic contact connector and a microswitch. Background Art
[0002] In recent years, with the continuous miniaturization of electronic products, especially in fields such as microwave switches, the electrical interconnection between various modules has become an important technical challenge. Traditional large-sized standard connectors are increasingly difficult to meet the ever-stricter space limitations and technical requirements, making the research and development of new connectors particularly important. Such connectors not only need to have a compact structure but also ensure reliable electrical performance, while being easy for rapid assembly and maintenance to adapt to the miniaturization trend of modern electronic products.
[0003] In existing technologies, in order to achieve the electrical interconnection between modules inside small-sized electronic products, commonly used methods include but are not limited to: standard connectors, wire soldering, and customized elastic sheet connections, etc.
[0004] However, although standard connectors have high reliability and standardization, their application scope is greatly limited under size constraints; wire soldering can achieve relatively flexible connections, but problems such as poor soldering and bad soldering are likely to occur during the soldering process, and the operation is complex, which is not conducive to large-scale production; while customized elastic sheet connections can overcome the above problems to a certain extent, but their design and manufacturing are difficult and their versatility is poor. These problems lead to difficulties in the rapid interconnection between modules, especially in precision devices such as microwave switches, where the limitations of standard connectors are more obvious and cannot meet the requirements of efficient and rapid assembly. Summary of the Invention
[0005] In order to overcome the deficiencies of the prior art, this application provides a micro double elastic contact connector, which can improve the reliability and stability of the connector, reduce production costs, achieve the technical effect of being suitable for installation in narrow spaces, and ensure good connectivity and signal transmission quality, especially in radio frequency signal transmission circuits.
[0006] This application is realized through the following technical solutions:
[0007] A micro double-elastic contact connector, including an elastic body, which is installed in a fixed medium; a clamping body extends from the upper part of the elastic body, and the clamping body is used to clamp the electrical connection pins of the first electrical component in the width direction of the elastic body; a limiting part is arranged in the middle of the elastic body, and the limiting part is used to achieve interference press-fitting with the fixed medium; a butting body extends from the lower part of the elastic body, and the thickness of the butting body is less than that of the elastic body, which is used to contact the electrical connection contacts of the second electrical component, and when the butting body contacts the contacts, the butting body forms a deformation that bends along the thickness direction of the elastic body.

[0051] Embodiment 1
[0052] As Figures 1-2 shown, this embodiment discloses a micro double-elastic contact connector, including an elastic body 1 in a plate-like structure, and the elastic body 1 is installed in a fixing medium 8; a clamping body 2 extends from the upper part of the elastic body 1, and the clamping body 2 is used to clamp the contact pin 6 of the first electrical component in the width direction of the elastic body 1; a limiting part is provided in the middle of the elastic body 1, and the limiting part is used to achieve interference press-fitting of the fixing medium 8; a contact body 5 extends from the lower part of the elastic body 1, and the thickness of the contact body 5 is less than the thickness of the clamping body 2, which is used to contact the contact point 7 of the second electrical component. When contacting, the contact body 5 forms a deformation that bends along the thickness direction of the elastic body 1, achieving the effects of improving the operation convenience and quick disassembly and assembly of the microwave switch connector. Moreover, as a whole, the connector adopts an integrated molding structure, which can significantly improve the overall strength and stability, reduce potential failure points caused by the assembly of multiple components, improve the reliability of the connector, and in the connection settings with the first electrical component and the second electrical component, the contact pin 6 and the contact point 7 are in a mutually perpendicular state on the contact connection surface, reducing the influence of their respective radiation waves during signal transmission and ensuring the signal transmission quality.
[0053] Specifically, as Figure 1As shown, on both sides of the upper end of the elastic body 1 extending symmetrically in the width direction are the first clamping arm 21 and the second clamping arm 22. The first clamping arm 21 and the second clamping arm 22 form the clamping body 2. The electrical connection probe 6 of the first electrical component is clamped between the first clamping arm 21 and the second clamping arm 22. An arc-shaped groove 24 adapted to the electrical connection probe 6 of the first electrical component is provided on the inner sides of the first clamping arm 21 and the second clamping arm 22 to increase the stability and reliability of the clamping. In addition, a guiding bevel 25 is provided on the inner side of the opening of the first clamping arm 21 and the second clamping arm 22 to facilitate the insertion and extraction of the probe 6 and reduce the operation difficulty.
[0054] As Figure 1 shown, a positioning shoulder 23 is provided at the lower end of the clamping part. A groove 24 away from the abutting surface is provided at the root of the positioning shoulder 23. The design of the positioning shoulder 23 makes the clamping part more stable when clamping the electrical connection probe 6 of the first electrical component, and can also position the elastic body 1 to facilitate the accuracy of installation and prevent over-insertion from damaging the elasticity of the abutting body 5.

The shape of the groove 24 can be circular, elliptical or rectangular, etc., and the specific shape can be selected according to actual needs.
[0055] As Figure 1 shown, the limiting part is a protrusion 3 symmetrically arranged in the middle of the elastic body 1 in the width direction of the elastic body 1. An opening 4 for providing deformation space for the protrusion 3 is provided inside the elastic body 1 at the protrusion 3. Specifically, the opening 4 is in an elliptical structure or can also be a waist-shaped hole. The long side of the opening 4 is arranged along the length direction of the elastic body 1, and the long side dimension of the opening 4 is not less than the height of the protrusion 3.

Moreover, a first bending portion 51 is provided on the contact body 5 to ensure that after the contact body 5 touches the contact point 7, it can deform along the designed path, without interfering with other components and without deviation, ensuring the stability of the contact of the contact point 7 and facilitating installation; the portion of the contact body 5 in contact with the contact point 7 electrically connected to the second electrical component has an arc-shaped structure to increase the contact area, improve the reliability and stability of the contact, and ensure the transmission quality. Specifically, the bending amplitude is within 45 degrees.

Among them, the chemical milling forming process also has a high processing efficiency and reduces the production cost; the metal material can be a bronze alloy. Using the bronze alloy as the material of the elastic body 1 can ensure that the connecting member has good electrical conductivity and corrosion resistance, and at the same time has sufficient elastic deformation ability to ensure the stability and reliability during long-term use; at the same time, other metal materials with good elasticity and electrical conductivity, such as copper-nickel alloy, phosphor bronze, etc., can also be selected as the metal material.
[0058] In terms of specific dimensions, the width of the elastic body 1 is in the range of 0.5 - 1.5 mm, the thickness is in the range of 0.2 - 1 mm, and the length is in the range of 1 - 3 mm; the width of the contact body 5 is in the range of 0.1 - 0.5 mm, and the thickness is in the range of 0.02 - 0.2 mm; the height of the protrusion 3 is in the range of 0.5 - 2 mm; this size design ensures the mechanical strength while achieving precise dimensional control, ensuring the stability and reliability of the connecting member in a narrow space. Specifically, the width and thickness design of the elastic body 1 enables the connecting member to have sufficient rigidity to prevent deformation during the plugging and unplugging process, and at the same time can maintain good elastic performance to ensure the contact stability during long-term use; the width and thickness design of the contact body 5 further optimizes the contact area and contact pressure of the contact point 7, improves the reliability and electrical conductivity of the electrical connection, and also reduces the cross-section and enhances the anti-interference ability; this design is particularly suitable for electrical interconnection in miniaturized electronic devices such as microwave switches, and can effectively improve the operation convenience and the rapid interconnection between modules.
[0059] The implementation principle of the embodiments of this application is as follows: By designing a micro double-elastic contact connector, efficient electrical interconnection is achieved at the millimeter-scale size.

It has good elasticity and conductivity, and can meet the high-performance requirements of precision equipment such as microwave switches. Compared with traditional standard connectors and welding interconnection methods, the connector of the present invention has the advantages of small size, convenient operation, easy and quick disassembly and assembly. Moreover, in the connection setting with the first electrical component and the second electrical component, the pins 6 and the contact points 7 are perpendicular to each other on the contact connection surface, reducing the influence of their respective radiation waves during signal transmission, ensuring the signal transmission quality, and significantly improving the performance and maintenance efficiency of precision equipment such as microwave switches.
