When such optical interconnection is performed, processing of the transmitted optical signal is performed by the electronic device. The boundary device that connects these electronic devices requires an optical-electric mixing system that includes optical waveguides, photoelectric conversion elements, LSIs and switches for electronic control, and electric circuits for driving electronic components. Become. In particular, in order to realize a high-speed and broadband communication system, there is an increasing demand for devices including photoelectric conversion elements such as Vertical Cavity Surface Emitting Laser (VCSEL), Laser Diode (LD), and Photo diode (PD).

In response to such demands, the light emitted from the semiconductor package is optically connected by an optical fiber abutted from the back of the package, and when the semiconductor package is mounted, an opening is provided in the substrate to be mounted.

In this prior art, when the optical element and the optical fiber are coupled, it is necessary to make a through hole in the substrate on which the semiconductor package is mounted, resulting in a complicated substrate manufacturing process and high cost. was there.
Moreover, since the optical fiber protrudes perpendicularly from the substrate surface, there is a problem that the apparatus becomes large.
Furthermore, it is necessary to prepare components for fixing the optical fiber separately from the electrical connector and the substrate for mounting the semiconductor package, resulting in a problem of high cost.

  The present invention has been made in order to solve the above-described problems. The optical connection component is integrated into the electrical connection component so that the electrical connection direction and the optical connection direction are the same, and the optical fiber is connected in the electrical connection direction.

In addition, guide grooves 12b are formed on both side surfaces of the base portion 12 with the groove direction parallel to the hole direction of the through hole 12a. A pair of optical connection positioning pin holes 12c are formed on the upper surface (flat surface) of the base 12 with the through hole 12a sandwiched between the hole direction parallel to the hole direction of the through hole 12a. Further, the optical fiber insertion hole 13a is formed in the flange portion 13 so that the through hole 12a communicates with the outside so that the hole direction is orthogonal to the hole direction of the through hole 12a.

  As shown in FIG. 4, the optical path conversion device 14 is configured such that a plurality of cores 15 that propagate light are two-dimensionally arranged and embedded in a clad 16 having a refractive index smaller than that of the core 15. Yes. The clad 16 is formed in a rectangular parallelepiped having a cross-sectional shape equivalent to the inner shape of the through hole 12a, and is a first end surface 16a, a second end surface 16b, and a mirror surface located between the first end surface 16a and the second end surface 16b. 16c. Each core 15 is configured to reach the mirror surface 16c from the first end surface 16a, bend back at the mirror surface 16c, and reach the second end surface 16b. The first core end surface 15a of the core 15 is exposed on the first end surface 16a in a 2 × 4 matrix, and the second core end surface 15b is exposed on the second end surface 16b in a 2 × 4 matrix.

The optical fiber 17 is inserted into the optical fiber insertion hole 13a so that the optical fiber 17 is fixed to the through hole 12a and the fiber end face is in contact with the second end face 16b, and is inserted into the optical fiber insertion hole 13a of the optical connection part ferrule 11 by an epoxy resin adhesive. The optical connecting component 10 is assembled. At this time, the optical fiber insertion hole 13a is formed in the flange portion 13 coaxially with the second core end surface 15b, and the optical fiber 17 has its optical axis aligned with the optical axis of the core 15 at the second core end surface 15b.

Further, the upper surface of the optical connection component ferrule 11 and the first end surface 16a of the optical path conversion device 14 constitute a first optical signal input / output surface, and the second end surface 16b of the optical path conversion device 14 serves as a second optical signal input / output surface. It is composed. The guide groove 12b extends in a direction orthogonal to the first optical signal input / output surface on a side surface in a direction orthogonal to both perpendiculars of the first and second optical signal input / output surfaces of the optical connection component ferrule 11.

Here, the refractive index difference between the core 15 and the clad 16 may be any refractive index difference that allows an optical signal to propagate through the core, and is preferably about 0.1 to 1.0%. The material may be a material having a necessary refractive index and low loss with respect to the propagation wavelength. For example, amorphous glass, PMMA (polymethyl methacrylate), quartz, silicone resin, epoxy resin, A polyimide resin or the like can be used. Further, the cross-sectional shape of the core 15 is not limited to a core having a rectangular cross section, and may be a core having a circular or elliptical cross-sectional shape, for example.
The mirror surface 16c is a reflecting mirror that changes the optical path. If the mirror angle is 45 degrees, the optical path can be changed by 90 degrees. That is, the mirror angle is appropriately set according to the conversion angle of the optical path. Further, if a metal thin film such as gold or aluminum or a dielectric multilayer film such as magnesium oxide is formed on the mirror surface 16c, the reflectance of the mirror surface 16c can be improved. Further, the mirror surface 16c may be provided with a filter function so that the transmitted light is incident on another optical waveguide separately for the transmitted light and the reflected light.

  In the optical connecting component 10 configured as described above, the light incident on the second core end surface 15b of the core 15 via the optical fiber 17 travels through the core 15 to the mirror surface 16c, and travels through the optical path at the mirror surface 16c.

Then, the light whose optical path is converted by 90 degrees on the mirror surface 16c travels in the core 15 from the mirror surface 16c to the first core end surface 15a, and is emitted from the first core end surface 15a. Similarly, light incident on the core 15 from the first core end surface 15a travels through the core 15 to the mirror surface 16c, and its optical path is converted by 90 degrees at the mirror surface 16c. Then, the light whose optical path is converted by 90 degrees on the mirror surface 16c travels in the core 15 from the mirror surface 16c to the second core end surface 15b, and is emitted from the second core end surface 15b to the optical fiber 17.

As shown in FIG. 6, each optical connection component housing portion 8 has a rectangular cross-section opening on the upper surface and side surface of the electrical connection ferrule 4, and is formed slightly larger than the outer shape of the optical connection component ferrule 11. And the elongate leaf | plate spring 18a as an elastic member is attached to the bottom face of the optical connection component accommodating part 8 in convex shape. Further, the elongated leaf springs 18b are respectively attached to the opposite side surfaces of the optical connection component accommodating portion 8 in a convex shape with the length direction thereof coinciding with the pin insertion direction. The width L1 of the leaf spring 18b is narrower than the groove width L2 of the guide groove 12b.
Then, the optical connection component 10 is inserted into the optical connection component housing portion 8 from the upper surface side of the electrical connection ferrule 4. At this time, the leaf spring 18b attached to the opposite side surface of the optical connection component housing portion 8 enters the guide groove 12b, and the optical connection component 10 is guided by the leaf spring 18b and elastically deforms the leaf spring 18b. The optical connecting component accommodating portion 8 is inserted into the optical connecting component accommodating portion 8 until it abuts against a leaf spring 18a attached to the bottom surface of the optical connecting component accommodating portion 8. Thereby, the optical connection component 10 is elastically supported by the elastic force of the pair of leaf springs 18 b attached to the opposite side surfaces of the optical connection component housing portion 8, and is attached to the bottom surface of the optical connection component housing portion 8. It is attached to the electrical connection ferrule 4 in a state where the upper surface of the base 12 is protruded by the elastic force of the attached leaf spring 18a. Accordingly, the optical connection component 10 is disposed in the optical connection component housing portion 8 of the electrical connection ferrule 4 so as to be movable in the pin insertion direction. The leaf spring 18b functions as an elastic support member that elastically supports the optical connection component 10, and also functions as a guide protrusion that engages with the guide groove 12b and guides the optical connection component 10 to move in the pin insertion direction.

  Here, since the width L1 of the leaf spring 18b is narrower than the groove width L2 of the guide groove 12b, the optical connecting component 10 is slightly movable in the groove width direction of the guide groove 12b. Further, the optical connection component 10 is movable in the groove direction of the guide groove 12b. Furthermore, the optical connecting component 10 is slightly movable in the groove width direction of the guide groove 12b and the direction orthogonal to the groove direction. In other words, the optical connecting component 10 is movable in a direction orthogonal to the first end surface 16a, is movable in a small amount in a direction orthogonal to the second end surface 16b, and is further provided on the first end surface 16a and the second end surface 16b.

Here, the optical / electrical collective connection using the optical / electrical collective connector 100 configured as described above will be described.
First, although not shown, the wiring board 20 as a connection target is mounted with an LSI for electronic control, a switch, an electric circuit for driving an electronic component, an optical waveguide, and an optical element. Then, pins (not shown) connected to the electric circuit are extended from one surface of the wiring substrate 20, an optical waveguide and a light transmitting / receiving part of an optical element are formed on one surface of the wiring substrate 20, and a pair of positioning pins 21 are provided. It extends from one surface of the wiring board 20 with the light transmitting / receiving part interposed therebetween. The arrangement and arrangement of the electrical connection pins, the light transmitting / receiving portions and the positioning pins 21 in the wiring board 20 are as follows: the socket 6 in the optical / electrical collective connection connector 100, the first core end face 15a of the core 15, and the optical connection positioning pins. It is the same as the arrangement arrangement state of the holes 12c.
Next, as shown in FIG. 2, the electrical connection ferrule 4 is connected to the connection terminal 2 a of the electrical wiring 2 of the electrical wiring board 1 by a joining means such as solder 9 as shown in FIG. It is attached. Then, the optical connection components 10 are respectively stored in the optical connection component storage portion 8. Thereby, the optical / electrical collective connector 100 is attached to the electric wiring board 1 as shown in FIG.

  Next, the wiring board 20 is pressed against the optical / electrical collective connector 100 from above, and the clasp 7 is fitted into the wiring board 20. As a result, the wiring board 20 is elastically supported by the clasp 7 and attached to the optical / electrical collective connector 100. Further, the electrical connection pins of the wiring board 20 are press-fitted into the socket 6 of the electrical connection ferrule 4, and electrical connection between the electrical circuit of the wiring board 20 and the electrical circuit of the electrical wiring board 1 is performed. Further, as shown in FIG. 3, a pair of positioning pins 21 are inserted into the respective optical connection positioning holes 12c. At this time, the optical connecting part ferrule 11 moves in the groove width direction of the guide groove 12b, the groove width direction of the guide groove 12b, and the direction perpendicular to the groove direction, and the light transmitting / receiving section of the wiring board 20 and the first core end face 15a. And positioning. Further, the optical connection component ferrule 11 is pressed against one surface of the wiring board 20 and sinks into the optical connection component housing portion 8 while elastically compressing the leaf spring 18 a attached to the bottom surface of the optical connection component housing portion 8. Then, the first core end surface 15 a comes into contact with the light transmitting / receiving portion of the wiring board 20 by the repulsive force of the elastically compressed leaf spring 18 a, and the optical element and the optical fiber 17 are optically connected via the optical path conversion device 14.

Thus, this optical / electrical collective connector 100 is formed on the electrical connection ferrule 4 so that the socket 6 has the pin insertion directions parallel to each other and the pin insertion opening is opened on the upper surface of the electrical connection ferrule 4. The electrical connection component 3 and the optical path conversion device 14 are disposed in the optical connection component ferrule 11 so that the first end surface 16a is flush with the flat surface of the optical connection component ferrule 11, and positioning pin holes for optical connection 12c is formed on the flat surface so as to be orthogonal to the flat surface of the optical connection component ferrule 11, and the optical connection component 10 in which the optical fiber 17 is optically coupled to the second core end surface 15b of the optical path conversion device 14; The optical connection component 10 is attached to the electrical connection component 3 so as to be movable in the pin insertion direction so that the first end surface 16a protrudes from the upper surface of the electrical connection ferrule 4 It has been. Therefore, the insertion direction of the electrical connection pins of the wiring board 20 into the socket 6 and the insertion direction of the positioning pins 21 of the wiring board 20 into the optical connection positioning pin holes 12c coincide with each other. Electrical connection with the wiring board 1 and optical connection between the light transmitting / receiving part of the wiring board 20 and the optical fiber 17 can be realized simultaneously. Further, unlike the conventional example, there is no need to provide a hole for connecting an optical fiber in the wiring board, and the manufacturing cost can be reduced.

Further, since the leaf spring 18a is arranged to urge the optical connecting component 10 in the direction of extending from the upper surface of the electrical connection ferrule 4, the wiring board 20 is attached to the optical / electrical batch connection connector 100. In addition, the repulsive force of the leaf spring 18a brings the first core end face 15a and the light transmitting / receiving portion of the wiring board 20 into close contact with each other, improving the reliability of the optical connection and reducing the loss in the optical connection.

Further, the guide groove 12b is formed in the optical connection component ferrule 11, and the leaf spring 18b that engages with the guide groove 12b and guides the optical connection component 10 is formed on the inner wall surface of the optical connection component housing portion 8. Mounting of the optical connection component 10 to the electrical connection ferrule 4 is simplified. Further, the leaf spring 18b elastically supports the optical connection component ferrule 11, so that the optical connection component 10 is prevented from coming off, and the optical / electrical batch connection connector 100 is easily handled.
Since the groove width of the guide groove 12b is slightly larger than the width of the leaf spring 18b and the optical connection component 10 is provided with the optical connection positioning hole 12c, the positioning pin 21 of the wiring board 20 is connected to the optical connection positioning hole. By simply inserting it into 12c, the first core end face 15a and the light transmitting / receiving portion of the wiring board 20 are positioned, and the optical connection work can be performed easily and with high accuracy.

  Further, since the optical path conversion device 14 is used as means for converting the optical path, the first core end face 15 a is exposed to the first end face 16 a of the clad 16. Therefore, when optically connecting the light transmitting / receiving part of the wiring board 20 and the optical connection component 10, the occurrence of an angular deviation in the optical connection part is suppressed, and an increase in loss due to the angular deviation can be prevented. In addition, since the cores 15 are two-dimensionally arranged, it can be efficiently and collectively connected to optical waveguides and optical elements arranged one-dimensionally or two-dimensionally, and the cost of the connector can be reduced. Can do.

Further, the optical path conversion device 14 is inserted and fixed in the through hole 12 a of the optical connection component ferrule 11. Therefore, since the optical axis adjustment of the optical connecting part ferrule 11 and the optical path conversion device 14 can be performed based on the hole machining accuracy of the through hole 12a and the external accuracy of the optical path conversion device 14, the manufacturing cost can be reduced, Cost reduction of the electrical batch connection connector can be achieved.
In addition, since the optical fiber 17 is inserted and fixed in the optical fiber insertion hole 13a, the optical axis adjustment with respect to the optical path conversion device 14 is performed with high accuracy by increasing the hole machining accuracy of the optical fiber insertion hole 13a. The optical fiber 17 can be attached. Therefore, the optical axis adjustment work when attaching the optical fiber 17 is simplified.
In addition, since the wiring board 20 is elastically fixed to the optical / electrical batch connection connector 100 by the clasp 7, the electrical connection state and the optical connection state between the wiring board 20 and the optical / electrical batch connection connector 100 are maintained, and the electrical connection is achieved.
