Contact module housing, contact module and optical fiber connector

Abstract

The present invention relates to a contact module housing, a contact module and an optical fiber connector. The contact module housing is composed of a housing body that is inserted in a module installation hole of a corresponding connector frame from the back going forward. The housing body is provided with a housing stopping surface that is forward in limiting direction and used for being in stopping cooperation with a module stopping structure in the connector frame so as to restrict the forward moving limit of the housing body. The housing body is internally provided with a contact installation hole for the installation of a corresponding optical fiber contact. The housing body is further provided with a module locking hook configured to be elastically clamped in a module clamping groove in the hole wall of the module installation hole so as to limit the housing body from moving backward. The contact module housing provided by the invention can be assembled / disassembled with the connector frame on the spot. The contact module and the optical fiber connector are provided with the above contact module housing.

Description

technical field [0001] The invention relates to a contact module, an optical fiber connector and an optical fiber connector assembly in the field of signal transmission. Background technique [0002] In the cabinet of communication equipment, data communication needs to be carried out between the backplane and the sub-board. At present, the relatively mature communication method is to use high-speed differential electrical connector transmission. Due to the defects of electrical signal transmission, this communication method has certain advantages. transmission limit. [0003] However, if the data communication between the backplane and the sub-board is transmitted by optical fiber, the transmission capacity will be much higher than that of the existing electrical transmission. Existing optical fiber connectors used between the mechanism backplane and sub-boards, such as the "optical connector for backplane" disclosed in Chinese patent CN104412141A, the optical connectors d...

Problems solved by technology

The existing problem of this kind of optical connector is that the plug contacts and socket contacts do not have the function of on-site removal, and when multiple contacts are used at the same time, when part of the optical path is damaged, they cannot be quickly replaced.

The existing problems of this dust-proof structure are: (1) the process of cooperation between the push plate and the dust-proof plate is as follows: figure 1 Shown: During the pushing process of push plate 1 and dust-proof plate 2, F1, F2, and F3 respectively represent the thrust direction of the push plate on the dust-proof plate during the rotation process of the dust-proof plate. During the rotation of the plate, the length of the force arm of the thrust of the push plate to the dustproof plate is always changing. When the push plate is in a vertical state, the force arm is the largest. That is to say, in order to realize the rotation of the dustproof plate, the required thrust is getting larger and larger. On the one hand, it will increase the difficulty of inserting the plug and socket; In order to realize the rotation of the dustproof plate, this large thrust will increase the insertion speed of the plug, and the plug and socket will have a greater impact to complete the insertion process of the plug and socket, which will reduce the service life of the plug. In addition, on the dustproof plate After being turned up completely, the dustproof plate cannot be hidden in the push plate, which will increase the size of the plug, which is not conducive to the miniaturization of the plug; (2) Even with the protection of the dustproof plate, it is still impossible to ensure that the optical fiber ferrule is in absolute position. In a dust-free environment, once the end face of the fiber optic ferrule is covered with dust, and the radius of the optical path formed by the fiber optic ferrule is relatively small, the optical density per unit area is relatively large, and the optical signal is highly sensitive to dust and dirt. Transmission is greatly disadvantaged
