[0028] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] The present application provides a LN electro-optical switch, such as Figures 1 to 3 As shown, it includes a crystal bracket 1, the crystal device is located in the crystal bracket 1, and gold-plated electrodes are provided at both ends of the crystal device. The crystal bracket 1 includes an installation area 121 for placing the crystal, and the installation area 121 is axially symmetrically provided with a limiting groove 122. A flexible rubber strip is provided in the limiting groove 122, and the flexible rubber strip abuts against the crystal device.

[0030] By setting a flexible rubber strip to abut against the crystal device, the friction force on the crystal device in the crystal bracket 1 is increased, and the crystal is prevented from sliding in the installation area 121 and causing displacement, thereby ensuring the stability of the working process of the crystal device. In addition, the symmetrical limit groove 122 avoids stress concentration caused by the only fixed point of the crystal device after the component is packaged, and avoids the crystal device from being affected by stress and causing unstable use or even damage, thereby ensuring the service life and working stability of the LN electro-optical switch. The structure is compactly arranged, making the overall size small and close to the crystal size, which greatly facilitates the integrated installation during use and is easy to promote and use.

[0031] Preferably, the installation area 121 includes a rectangular body, a corner of the rectangular body is provided with a break 127, and a limiting groove 122 is formed along the break 127 extending away from the rectangular body. In this way, four limiting grooves 122 can be provided.

[0032] Furthermore, the fracture 127 penetrates the rectangular body, and the limiting groove 122 is arc-shaped. The arc-shaped limiting groove 122 has a better limiting and wrapping effect on the flexible rubber strip located inside it, preventing the flexible rubber strip from coming out of the limiting groove 122 or shifting excessively due to force deformation, thereby ensuring the limiting stability of the flexible rubber strip on the crystal device, stably achieving the force dispersion effect at each limit position, and avoiding stress concentration.

[0033] The length of the flexible rubber strip is set to be slightly smaller than the length of the limiting groove 122. The flexible rubber strip abuts against the crystal device and will produce slight deformation when subjected to pressure, thereby ensuring that the flexible rubber strip has a certain deformation space in the limiting groove 122, preventing the flexible rubber strip from extending outside the limiting groove 122 and affecting the connection between the crystal bracket 1 and other components, thereby avoiding loose connections between components.

[0034] Furthermore, the crystal bracket 1 includes a shell 11 and a bracket body 12 having an installation area 121. The bracket body 12 is located in the shell 11 and is coaxially arranged with the shell 11. The bracket body 12 is provided with a contact portion 123 protruding from the shell 11.

The contact portion 123 is provided with a contact port 124, and the contact port 124 is connected to the installation area 121.

[0035] Preferably, the contact opening 124 is located between two adjacent limiting grooves 122 and is at the same distance from the two adjacent limiting grooves 122, so as to further improve the force balancing effect of the overall structure.

[0036] It should be noted that the housing 11 and the bracket body 12 may be integrally formed, and contact portions 123 are provided at both ends of the bracket body 12 .
