Description

[Detailed Description of the Invention] The present invention relates to an optical communication connector used in various communication devices.

Conventionally, this type of optical communication connector has screw parts 1 and 1' for connection and a flange part 2 for fixing the connector body, as shown in Fig. 1, and the flange part 2 has a fixing hole. 3 is a provision.

As shown in FIG. 2, the connector constructed in this manner is attached to the front surface 4 of the circuit package unit with mounting screws 5, and a connecting plug 6 is screwed in to connect the optical signal transmission line.

However, since the flange portion 2 of such an optical communication connector is large, the height H of the front surface 4 of the circuit package unit must be large, so it is necessary to mount it using a package unit dedicated to optical components.

However, there are disadvantages in recent communication devices that require high-density packaging and also need to be mounted together with conventional electronic components.

That is, in order to mount electronic components together, unless the size of the flange portion 2 is compatible with the mounting pitch of the conventional electronic circuit package, it is necessary to increase the mounting width of the conventional circuit package, which impedes high-density mounting.

An object of the present invention is to provide an optical communication connector that solves these problems and can be installed in conventional electronic circuit package units.

The optical communication connector according to the present invention includes a plug provided with an optical signal transmission line member, a coupling member for the plug having an introduction hole for the transmission line member and a screw groove formed on the outer peripheral surface, and a circuit board or the like. a support member having a screw hole to be fixed to the mounting member and an introduction hole for the transmission path member, the support member having at least a flat wall surface to be fixed to the mounting member, and a substantially columnar shape extending in the axial direction of the coupling member; Characterized by being a body.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 shows an embodiment of the optical communication connector according to the present invention. The connector 10 has two planar parts parallel to the longitudinal plane so that it can be easily fixed when mounted on an electronic circuit package unit, etc. A support member 11 is made of an elliptical columnar block having a diameter of 13.13', and has a plurality of screw holes 14 in a plane part 13.13', and connection plugs 17 are provided at both ends of the support member 11 in the longitudinal direction. Threaded portion 16 to engage
．． Plug joint member 15.15' with 16' provided on the outer periphery
It consists of

Note that the support member 11 and the plug connection member 15.15'
A through hole 12 for inserting a connecting plug 17 is provided in the central shaft portion of the connector.

FIG. 4 shows a state in which an optical communication connector having such a structure is mounted on an electronic circuit package board.

The optical communication connector 10 can be easily attached to the package substrate 20 with the mounting screws 21, and the mounting height dimension is H.
It can be seen that ' is extremely small compared to the same dimension H of the conventional connector.

Note that the supporting member 11 and the plug connecting member 15.15 may be individually processed and assembled, but they may also be integrally formed from, for example, a single round bar.

Further, the support member 11 shown in the above embodiment can be similarly implemented as long as it is a substantially columnar body whose wall surface, which is fixed to at least a circuit board or the like, is a flat surface.

As explained above, according to the present invention, it is possible to obtain an optical communication connector that can be easily mounted on a conventional electronic circuit package board or the like.

Furthermore, since the optical communication connector according to this invention can be mounted on a package substrate or the like with a reduced height, high-density packaging is possible and communication devices can be downsized.
