The housing 23 on the package side is a connector housing on the package side that mates with the housing 20 on the back panel side, and holds the optical element 24. The housing 23 on the package side is provided with a float structure at two locations, as shown by broken lines in the figure, and is float-held by the package 25 so as to be movable in the vertical direction in the figure.

As shown in FIG. 1 (8), the housing 23 on the package side has a nut as a plate-shaped fixing member fixed to a holding surface 26 of the housing 23 and a tip of a protrusion 27 extending from the holding surface 26. It is held in the package 25 by a shaped member 28. This state of holding the float will be explained in more detail with reference to FIGS. 2 and 3.

On the other hand, as shown in FIG. 3, in the direction perpendicular to the insertion direction of the package 25, that is, in the left-right direction in the figure, the width of the float hole 33 of the disc-shaped member 30 is smaller than the width of the float shaft part 35 of the protrusion 27. Since there is a large gap, the float shaft portion 35 is movable within the float hole 33.

Further, the axial position of the nut-shaped member 28 is
At this time, the distance between the holding surfaces 26 and 32 is determined by the position of the surface 36 so that the distance between the holding surfaces 26 and 32 is slightly larger than the thickness of the package 25. It is set. These allow the housing 23 on the package side to float in a direction perpendicular to the direction in which the package 25 is inserted.

As shown in FIG. 4, the disc-shaped member 30 has an outer circumferential surface 37 that is approximately the same shape as the through-hole 29 provided in the package 25, and has a shape that allows it to be attached to the through-hole 29 without shifting. be. The float hole 33 has a protrusion 2 inside.
7 has a shape that can be penetrated and a shape that allows necessary float. That is, a pair of parallel parts 38 are formed in the vertical direction in the figure, and the width of this part is made the same as the width of the protruding part 27, and the protruding part Float hole 33 for 27
The machine has an elliptical shape with a gap in the vertical direction. As the protrusion 27 moves in this gap, the housing 23 on the package side floats, but does not move in the left-right direction. Since the disc-shaped member 30 can be processed by molding or the like, the float hole 33 having a long circular shape can be easily manufactured precisely and at a low cost.

By making the cross-sectional shape circular, the float shaft portion 3
5 can move only in one direction along the longitudinal axis without rotating within the float hole 33 of the disc-shaped member 30. That is, the disc-shaped member 30 no longer rotates with respect to the package 25. Therefore, by providing the float structure at two or more locations as in the embodiment shown in the first prisoner, for example, the disk-shaped member 30 does not have to be fixed to the package 25 to prevent rotation, and the housing 23 on the package side relative to the package 25 The direction of movement is determined.

In this embodiment, the float direction is perpendicular to the optical axis of the element 24. If it is necessary to float the housing 23 in another direction, do not change the shape of the through hole 29, the disc-shaped member 301, or the nut-shaped member 28 (or make sure that the long axis direction of the protrusion 27 is in the direction you want it to float). By forming the housing 23 in this way, it is only necessary to change the floating direction of the housing 23.

Moreover, since the package has a simple shape that allows for easy precision machining of through holes, etc., the cost of package processing can be reduced. In addition, since the structure can be processed by mold forming, etc., which is easy to process with high precision, it is possible to realize a low-cost float structure if the structure affects the control of the float amount, etc., or has a complex shape with high precision.

Furthermore, when mounting a bookshelf-type package, there is a limit on the height of parts mounted on the package to avoid interference with adjacent packages, but according to the structure of the present invention, the surface on which the connector is mounted is No structure is required, and the pan cage side housing can be floated with a compact shape. Since there is no need to provide a float structure in the connector housing part, the mounting area for the connector element on the connector housing can be expanded, and the number of elements mounted can be increased.In addition, the mounting on the back side of the package is fixed. It is only necessary to provide a nut-shaped member, and there is no need for space that would interfere with neighboring packages, so it is possible to increase the packaging density of packages in units.

Furthermore, by floating the housing on the package side, there is no need to provide a float on the back panel side as used in conventional plug-in connectors. The housing on the back panel side can be fixed to the back panel. Therefore, even if the cable of the back panel side connector element connected to an external device is pulled, for example, the force will not be applied to the package inside the unit, increasing the reliability of the device. .
