Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to a pin socket for a multi-core optical fiber connector. Background Technology

[0002] As networks demand increasingly higher speeds for data transmission in fiber optic communications, the demand for fiber optic connectors is also growing, such as multi-fiber push-on (MPO) fiber optic connectors. Improving the assembly precision of MPO fiber optic connector components is a crucial issue. Currently, most MPO fiber optic connectors in the industry use ordinary pin headers. During use, the springs in MPO fiber optic connectors are prone to misalignment, affecting the assembly precision of the MPO fiber optic connector components, reducing the actual spring force during MPO fiber optic connector mating, and ultimately impacting the reliability of MPO fiber optic connector mating. Utility Model Content

[0003] In view of this, the purpose of this utility model embodiment is to provide a pin socket for a multi-core fiber optic connector, which can improve the precision of spring mounting of fiber optic connector components and the reliability of mating.

[0004] To address one of the aforementioned problems, the present invention provides a pin holder for a multi-core fiber optic connector. The pin holder includes at least two guide pins and a socket. The guide pins are connected to a first end of the socket. The socket is provided with a component mounting groove that passes through the socket. A spring countersunk hole is integrally formed at a second end of the socket. The first end is opposite to the second end. The spring countersunk hole communicates with the component mounting groove, and the inner diameter of the spring countersunk hole is larger than the inner diameter of the component mounting groove.

[0005] Optionally, the spring countersunk hole is arc-shaped, square, or other shapes.

[0006] Optionally, the first end of the socket is provided with a first slot, and the guide pin is provided with a second slot, wherein the guide pin and the socket are engaged with the first slot through the second slot.

[0007] Optionally, the outer diameter of the guide pin is in the range of 0.69825mm-0.69875mm.

[0008] Optionally, the center-to-center spacing of the guide pins ranges from 4.597 mm to 4.603 mm.

[0009] Optionally, the inner diameter of the spring countersunk hole ranges from 5.70 mm to 6.25 mm.

[0010] Optionally, the depth of the spring countersunk hole ranges from 0.5mm to 0.7mm.

[0011] This utility model has the following beneficial effects: by setting a spring countersunk hole on the socket, the spring countersunk hole can position the spring of the fiber optic connector during installation, so that the spring is installed in the correct position, thereby improving the assembly precision of the spring components of the MPO fiber optic connector. After installation, the spring countersunk hole can restrict the movement and tilting of the spring, stabilize the actual elastic force of the spring when the MPO fiber optic connector is mated, and improve the reliability of the MPO fiber optic connector mating.

[0017] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or there can be one or more intervening elements. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0019] In order to solve the technical problems existing in the prior art, the following will describe in detail one of the embodiments of the present utility model with reference to the accompanying drawings.

[0020] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a pin socket for a multi-core fiber optic connector. The pin socket includes at least two guide pins and a socket. The guide pins are connected to the first end of the socket. The socket is provided with a component mounting groove that passes through the socket. The second end of the socket is integrally formed with a spring countersunk hole, and the first end is opposite to the second end. The spring countersunk hole communicates with the component mounting groove, and the inner diameter of the spring countersunk hole is larger than the inner diameter of the component mounting groove.

[0021] Specifically, the component mounting slot is used to accommodate fiber optic connector components.

[0022] The guide pin can be made of metal, but is not limited to metal guide pins; the pin holder can be made of plastic, but is not limited to plastic pin holders. The fiber optic connector component mounting slot is used to accommodate fiber optic connector components, and the spring countersunk hole is used to install and limit the spring.

[0023] like Figure 2 As shown, Figure 2 This is a multi-view diagram of a spring countersunk hole, which is arc-shaped, square, or other shapes. The inner diameter of the spring countersunk hole ranges from 5.70mm to 6.25mm, preferably 5.8mm or 6mm. The depth of the spring countersunk hole ranges from 0.5mm to 0.7mm.

[0024] like Figure 3 As shown, Figure 3 This is a schematic diagram of a spring countersunk socket. The first end of the socket has a first retaining groove, and the guide pin has a second retaining groove. The guide pin engages with the socket via the second retaining groove and then with the first retaining groove. The second retaining groove is installed into the first retaining groove via the side of the socket and engages thereafter. This design facilitates the installation and removal of the guide pin.

[0025] The outer diameter of the guide pins ranges from 0.69825mm to 0.69875mm, preferably 0.6985mm. The center-to-center distance between the guide pins ranges from 4.597mm to 4.603mm, preferably 4.6mm. The center-to-center distance represents the distance between the centers of the two guide pin cylinders.
