Embodiment Construction

[0031] In order to further illustrate the technical means and technical effects adopted by the present invention, the present invention will be described in detail below in conjunction with the examples.

[0032] The present invention proposes a 22D optical fiber contact with a smaller volume than the current No. 20 optical fiber contact. A pair of 22D optical fiber contacts includes a pin contact and a socket contact. The pin contacts include a pin flange 1 1. Ceramic ferrule I2, the ceramic ferrule I is fixed with an optical fiber I3, one end of the ceramic ferrule I is fixed in the ferrule flange, and the other end is used to insert the jack contact. Jack contacts include jack flange 4, ceramic pin II 5, ceramic sleeve 6, metal sleeve 7, spring 8 and rear sleeve 9, and optical fiber II 10 is fixed inside ceramic pin II; jack flange includes flange Plate front diameter section 11, flange boss 12 and flange rear diameter section 13, the front diameter section, boss and rear d...

Abstract

The invention relates to an optical fiber contact member and an optical fiber connector using the same. The optical fiber contact member comprises a pin contact member and a jack contact member, wherein a ceramic pin I is arranged in the pin contact member, a ceramic pin II is arranged in the jack contact member, a rear sleeve pipe on the jack contact member is limited by means of a limiting mechanism in a plug connector, a rear diameter section of a jack flange plate can slide in the rear sleeve pipe, and two ends of a spring in the jack contact member are fixed to the rear end surface of a boss of the jack flange plate and the front end surface of the rear sleeve pipe respectively; and the ceramic pin I applies an insertion force to the ceramic pin II so that the spring is stressed to compress when the pin contact member and the jack contact member are inserted, and the ceramic pin I and the ceramic pin II are in tight contact to form reliable optical fiber connection under the action of spring forces. The optical fiber contact member is simple in structure and small in size, 22 pairs of the optical fiber contact members can be arranged on a No. 13(C) shell body, thus the node density and data transmission amount of the connector are improved, and the pin contact member and the jack contact member are of detachable structures, thereby facilitating the maintenance in the laterstage.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an optical fiber contact piece and an optical fiber connector using the contact piece. Background technique [0002] The existing J599 circular fiber optic connectors include 9 shell numbers, and the commonly used optical fiber contacts are No. 12 contacts, No. 16 contacts and No. 20 contacts, of which No. 20 contacts are the smallest in size. With the advancement of science and technology, all kinds of electronic equipment are developing towards miniaturization and integration, but the number of contacts of the existing J599 optical fiber connector can no longer meet the needs of some users. Taking the 13(C) shell as an example, the most The tight contact is a C98 contact, using the smallest size of the 20th optical fiber contact, including only 10 contacts. In order to meet the needs of users for high-density circular optical fiber connectors, the present i...
