Abstract

PURPOSE:To contrive the attachment and detachment of connector plugs and optical modules and the sure fixing of both by fixing the optical modules to these connector plugs by using screws. CONSTITUTION:The optical modules 1 are collectively mounted to one connector plugs 5 in the case of use of the plural optical modules 1 mounted with optical elements. The optical fiber connectors 7 (including ferrules 6 and bundles 14 of the optical fibers 8) of the number meeting the number of the optical modules 1 mounted to the connector plugs 5 are attached and detached. The coupling parts 2 of the optical modules 1 and the connector plugs are inserted into the optical module insertion holes of the connector plugs 5 until these parts come into contact with stoppers 15 or 16. The screws 4 are screwed into threaded holes 3 down to the recesses of the coupling parts 2 of the optical modules 1 and the connector plugs.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the attachment and detachment and fixing of a plurality of optical modules to a connector plug.

[0002]

2. Description of the Related Art An example in which one optical module and a connector plug are connected is shown in JP-A-3-259106. In this optical module, as shown in FIG. 6, a joint surface 19 between a lens holder 17 to which an optical element is attached and a receptacle housing 18 for connecting an optical fiber connector.
Are joined by welding.

There is an optical module in which two optical modules are connected to a connector plug. In this optical module, a lens holder to which an optical element is attached and a receptacle housing to which an optical fiber connector is connected are crimped. It is joined by that.

[0004]

However, in the above-mentioned prior art, when the lens holder part on which the optical element is mounted is defective, the part connected to the optical fiber connector must be replaced at the same time. This is not economical, especially in a connector plug that connects a plurality of optical fibers, because the failure of one optical module causes the failure as a whole.

Therefore, in the present invention, in a connector plug for connecting a plurality of optical fibers, it is possible to attach and detach the connector plug and the optical module, and to provide an optical module with a connector plug which can be securely fixed. To aim.

[0006]

The above object is solved by fixing a connector plug for connecting an optical fiber connector and an optical module having an optical element attached thereto with a screw.

[0007]

Operation: The connector plug is provided with a screw hole for fixing and can be attached and detached by connecting the optical module with the screw. Further, since the fixing is performed by the screw, it can be surely performed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is an optical module main body, 2 is a connecting portion with a connector plug, 3 is a screw hole, 4 is a screw, 5 is a connector plug, 6 is a ferrule, 7 is an optical fiber connector, and 14 is a bundle of optical fibers. is there.

FIG. 1 shows that, when a plurality of optical modules are used, the optical modules are collectively attached to one connector plug, and the optical fiber connectors (ferrule 6 and optical fiber) corresponding to the number of optical modules attached to the connector plug are attached. (Including the fiber 14).

Further, as a more reliable method of desorption,
The following can be considered. The figure explaining the example,
2 to 5.

Insert the connecting portion of the optical module with the connector plug into the insertion hole 12 of the optical module of the connector plug, insert until it hits the stopper 15 or 16, and tighten the screw 4 from the screw hole 3 to connect the connector. By tightening up to the recess 9 at the connecting portion with the plug, the optical module can be attached to and detached from the connector plug, and the fixing can be surely performed.

[0012]

According to the present invention, since the connector plug and the optical module are connected by using screws, they can be attached and detached. Particularly, in a connector plug that connects a plurality of optical modules, defective products can be replaced or each optical module can be replaced. This is convenient for matching the characteristics of the module.
