Light attenuated photoelectric mixed adaptor connector of ion

Abstract

The invention discloses a light attenuated photoelectric mixed adaptor connector, comprising a shell and an insulator which is fixed in the shell. Electrical contact elements extending back and forth are inserted in the insulator through a corresponding contact element mounting hole; light attenuated pin component mounting holes for assembling light attenuated pin components are transversely arranged in the insulator; the light attenuated pin components comprise a flange plate, a front light contact pin and a rear contact pin, wherein the flange plate is capable of stopping turning with the light attenuated pin component mounting holes, and is guided, moved and inserted in the front and rear directions; and the front light contact pin and the rear contact pin are fixed in the flange plateand connected with light attenuated fiber in the flange plate. The light attenuated pin components of the invention are assembled in the light attenuated pin component mounting holes by means of moving back and forth so as to enable the adapted plug, socket and adaptor to meet the design requirements after butt connection, thereby greatly reducing the situations of excessive or inadequate butt-connection elastic force.

Description

technical field [0001] The invention relates to the technical field of connectors for signal transmission. Background technique [0002] Optical attenuators are used in optical fiber transmission systems to reduce the optical energy in the fiber core and absorb excess signals. In order to facilitate the docking with the optical connector in the optical fiber transmission system, there is an optical attenuator with its own optical pin in the prior art, such as an optical attenuator disclosed in Chinese Patent Publication No. CN 2914132Y, from a flange A section of optical pins (ceramic pins) with guide sleeves (ceramic sleeves) protruding from each end, are used to connect with the optical pins of the optical connectors at the signal input end and signal output end respectively. An attenuating fiber for light attenuation is provided in the needle. In addition, most of the existing optical connectors are equipped with elastic elements (springs) that push the optical pins tow...

Problems solved by technology

However, the optical pins in the optical attenuator in the prior art are fixed to the body of the attenuator. When the optical pins of the optical connector are connected with the optical pins of the optical fiber attenuator, only the optical pins at the input and output ends can be used. The optical pins of the connector retreat to a proper position to ensure that the end faces fit together, which will make it difficult to ensure that the optical pins meet the requirements of elastic force when mating, especially when it is necessary to use optical attenuators mixed with electrical contacts. Since the electrical contact is a fixed rigid part, it will be more difficult for the structure of the existing optical attenuator to ensure the elastic force when the optical pins are mated due to the influence of the electrical contacts on the insertion direction when they are butted against each other.
