Description

Technical Field

[0001] The utility model relates to the technical field of dove prisms, and more specifically, to a dove prism fixing structure. Background Art

[0002] The fiber optic rotary connector is a 360-degree unlimited rotation device used to transmit optical communications. Its main function is to prevent signal interruption when transmitting optical fiber signals.

[0003] Square Dove prisms are usually fixed with metal casings, as stress concentration is easy to occur at the edges, which may cause the prism to break. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a dove prism fixing structure, including a prism shell located outside the dove prism, a through hole is opened inside the prism shell, the dove prism is placed in the through hole, and rounded grooves are provided at the four corners of the through hole. The corners of the dove prism are stuck in the rounded grooves.

[0005] In a preferred embodiment, side grooves are provided on the inner wall of the through hole between the rounded grooves, and the number of the side grooves is four.

[0006] In a preferred embodiment, a housing fixing ring is sleeved on the exterior of the prism housing, and a plurality of fixing holes are passed through the housing fixing ring.

[0007] In a preferred embodiment, a straight pressure zone is provided on the outer wall of the prism housing, and the pressure zone is located inside the fixing hole.

[0008] The technical effects and advantages of this utility model are:

[0009] The utility model can provide effective fixation for the dove prism, and by arranging rounded grooves at the corners of the through hole for installing the dove prism, stress concentration can be eliminated, thereby avoiding the problem of prism breakage caused by stress concentration at the edge of the dove prism.

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0014] like Figure 1-2 The illustrated structure of a dove prism fixing includes a prism housing 8 located outside a dove prism 1, a through hole 2 extending therethrough is formed inside the prism housing 8, the dove prism 1 is placed within the through hole 2, and rounded grooves 3 are formed at the four corners of the through hole 2, so that the corners of the dove prism 1 are clamped in the rounded grooves 3;

[0015] Based on the above, the dove prism 1 is stuck in the through hole 2, and the four corners of the dove prism 1 are respectively engaged with the rounded grooves 3 at the four corners of the through hole 2. The rounded groove 3 is a small rounded corner, which can eliminate the problem of stress concentration and avoid the problem of prism breakage due to stress concentration at the edge of the dove prism 1.

[0016] There are four side grooves 4 on the inner wall of the through hole 2 between the rounded grooves 3.

[0017] Based on the above, the corners of the Dove prism 1 are fitted with the rounded grooves 3 at the four corners of the through hole 2, and the through hole 2 located between the corners is provided with side grooves 4. The side grooves 4 do not fit with the edges of the Dove prism 1, thereby reducing the contact between the prism shell 8 and the edge of the Dove prism 1, and reducing the pressure exerted by the prism shell 8 on the prism itself.

[0018] A housing fixing ring 5 is sleeved on the outside of the prism housing 8 , and a plurality of fixing holes 6 are passed through the housing fixing ring 5 . A straight pressure zone 7 is opened on the outer wall of the prism housing 8 , and the pressure zone 7 is located inside the fixing holes 6 .

[0019] Based on the above, after the Dove prism 1 is stuck inside the through hole 2, the prism shell 8 with the Dove prism 1 is placed inside the shell fixing ring 5, so that the pressure area 7 on the prism shell 8 is placed on the inner side of the fixing hole 6, and then a stud or other fixing component is passed through the fixing hole 6 to act on the flat pressure area 7, and the prism shell 8 is fixed inside the shell fixing ring 5 to achieve the installation and fixation of the Dove prism 1.

[0020] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
