[0024] The embodiment of the present application provides a ferrule for optical fiber connection, including: a ferrule body 100, the ferrule body 100 has a first surface 110, a second surface 120 and a third surface 130, the first surface 110 and the third surface 130 are arranged opposite to each other, the second surface 120 is connected between the first surface 110 and the third surface 130, and a slot 150 is formed on the second surface 120 and the third surface 130. The inner wall surface of the slot 150 is provided with a fiber hole 160, and the fiber hole 160 penetrates the inner wall surface of the slot 150 to the first surface 110 along the length direction of the ferrule body 100. A stepped positioning block 170 is protruded on the inner wall surface of the slot 150 away from the first surface 110, and a guiding arc groove 171 is provided on the stepped positioning block 170 corresponding to the fiber hole 160, and the two side wall surfaces of the slot 150 are provided with a chamfered structure at one end away from the second surface 120.

[0025] The present application provides a stepped positioning block 170 protruding from the inner wall of the slot 150 to achieve positioning and cooperation with the stop block in the optical fiber connector, and provide positioning and support for the installation of the optical fiber; provides a guide arc groove 171 on the stepped positioning block 170 corresponding to the optical fiber hole 160 to guide and protect the optical fiber during installation to reduce damage; and provides a chamfered structure at one end of the two side walls of the slot 150 away from the second surface 120 to facilitate the installation and cooperation of the core body 100 with the stop block in the optical fiber connector.

[0026] In some embodiments, the ferrule body 100 has a thickness of 1.8 mm, a width of 5.2 mm, and a length of 3.7 mm. Thus, the ferrule for optical fiber connection is small in size, which saves more space in data centers and optical path device applications in high-density environments, improves space utilization, and thus saves a lot of costs.

[0027] In some embodiments, Figures 1 to 3 As shown, the ferrule body 100 has a fourth surface 140, which is arranged opposite to the second surface 120, and a venting groove 180 is formed on the fourth surface 140. Such arrangement can reduce the shrinkage rate of the ferrule body 100 during production, and make the ferrule body 100 more stable in size.

[0028] Specifically, the exhaust groove 180 is a square groove.

[0029] In some embodiments, Figures 1 to 3 As shown, the ferrule body 100 has an extension portion 190 at opposite ends, one surface of the extension portion 190 is flush with the first surface 110, and a guide hole 191 is provided through the extension portion 190, and the guide hole 191 is provided along the length direction of the ferrule body 100. In this way, the guide hole 191 can be positioned and docked with the guide pin in the optical fiber connector.

[0030] Specifically, the guide hole 191 is a circular hole.

[0032] In some embodiments, Figures 1 to 3 As shown, the outer side of the extension portion 190 is recessed to form a guide groove 193, which is arranged along the length direction of the ferrule body 100. This arrangement guides the insertion of the guide block on the optical fiber connector, thereby playing a positioning and guiding function, facilitating the connection between the plug body and the optical fiber connector.

[0033] First protrusions are arranged at intervals on the outer surface of the extension portion 190 , and a guide groove 193 is formed between two first protrusions.

[0034] A second protrusion is provided on the upper surface of the extension portion 190 and is connected to the first protrusion. When the ferrule body 100 is connected to the optical fiber connector, the second protrusion slides with the groove of the optical fiber connector to improve the connection stability between the ferrule body 100 and the optical fiber connector.
