Description

本発明は、光電気変換コネクタ、更に言えば、2種類(以上)の樹脂部材によって成形された光電気変換コネクタと、その製造方法に関する。 The present invention relates to a photoelectric conversion connector, more specifically, a photoelectric conversion connector formed of two types (or more) of resin members, and a manufacturing method thereof.

特許文献1に光電気変換コネクタとその製造方法の一例が示されている。光電気変換コネクタは、光信号と電気信号の間の変換機能を有するものであり、相手コネクタである電気コネクタと組み合わされて光電気変換装置を構成する。光電気変換コネクタを用いることにより、光電気変換コネクタに接続された光ファイバからの光信号を電気信号に変換して電気コネクタに伝達することができ、逆に、電気コネクタからの電気信号を光信号に変換して光ファイバに伝達することもできる。 Patent Document 1 discloses an example of a photoelectric conversion connector and a method for manufacturing the same. The opto-electrical conversion connector has a conversion function between an optical signal and an electric signal, and is combined with an electric connector that is a mating connector to form an opto-electrical conversion device. By using the opto-electrical conversion connector, the optical signal from the optical fiber connected to the opto-electrical conversion connector can be converted into an electric signal and transmitted to the electric connector. Conversely, the electric signal from the electric connector can be converted into an optical signal. It can also be converted into a signal and transmitted to the optical fiber.

特許文献1に開示された光電気変換コネクタには、光信号を電気信号に変換する光半導体素子としての受光素子又は電気信号を光信号に変換する発光素子と、これら受光素子及び発光素子(以下、受光素子と発光素子をまとめて「受発光素子」)を駆動する駆動デバイス、受発光素子および駆動デバイスを支持する支持部材、相手コネクタである電気コネクタの端子と接触し得る端子接点としての複数の端子、更に、受発光素子を駆動デバイスに接続するとともに駆動デバイスを端子に接続する導電材としてのワイヤボンディングが含まれる。 The photoelectric conversion connector disclosed in Patent Document 1 includes a light receiving element as an optical semiconductor element for converting an optical signal into an electrical signal or a light emitting element for converting an electrical signal into an optical signal, and the light receiving element and the light emitting element (hereinafter , A driving device for collectively driving the light receiving element and the light emitting element to drive the "light receiving and emitting element"), a supporting member for supporting the light receiving and emitting element and the driving device, and a plurality of terminal contacts capable of contacting terminals of an electrical connector which is a mating connector. And the wire bonding as a conductive material for connecting the light emitting/receiving element to the driving device and connecting the driving device to the terminal.

特許文献1に開示された光電気変換コネクタでは、受発光素子等は全て、第一樹脂部材のみによって一体成形されており、少なくとも受発光素子は、第一樹脂部材によって封止されている。
また、特許文献1に開示された光電気変換コネクタでは、第一樹脂部材のみに、光信号の挙動、例えば、光軸を調整するための反射面を備えた***部が設けられており、また、第一樹脂部材のみを通じて、光ファイバと受発光素子の間で光信号が伝達されるようになっている。尚、第一樹脂部材の外面は、第二樹脂部材によって一体成形されているが、第二樹脂部材は、単に、第一樹脂部材を覆っているだけで、この第二樹脂部材を用いて封止や挙動調整が行われるわけではない。
In the photoelectric conversion connector disclosed in Patent Document 1, all the light emitting/receiving elements and the like are integrally formed only by the first resin member, and at least the light emitting/receiving element is sealed by the first resin member.
Further, in the photoelectric conversion connector disclosed in Patent Document 1, only the first resin member is provided with a raised portion having a reflective surface for adjusting the behavior of an optical signal, for example, the optical axis, An optical signal is transmitted between the optical fiber and the light emitting/receiving element only through the first resin member. The outer surface of the first resin member is integrally molded with the second resin member, but the second resin member simply covers the first resin member and is sealed using the second resin member. It does not stop or adjust behavior.

特許文献1の光電気変換コネクタは、このように、第一樹脂部材のみによって受発光素子の封止を行い、また、第一樹脂部材のみによって挙動調整を行い、更に、第一樹脂部材のみを通じて光ファイバと受発光素子との間で光信号による通信を行うものである。 In this way, the photoelectric conversion connector of Patent Document 1 seals the light emitting/receiving element only with the first resin member, and the behavior is adjusted only with the first resin member, and further only through the first resin member. Communication is performed by an optical signal between the optical fiber and the light emitting/receiving element.

特許第5331837号公報Patent No. 5331837

受発光素子のような半導体は化学的に変化し易いことが知られている。このため、受発光素子の封止を行うにあたっては、一般には、受発光素子を化学的に破壊させないように、例えば、不純物イオン含有量を極力抑える等、封止材料の選択には細心の注意が必要となる。従って、例えば、特許文献1における第一樹脂部材の材料には、封止との関係で大きな制約が課されることになる。 It is known that a semiconductor such as a light emitting/receiving element is easily chemically changed. For this reason, when sealing the light emitting/receiving element, generally, in order not to chemically destroy the light emitting/receiving element, for example, the impurity ion content should be suppressed as much as possible, and the sealing material should be carefully selected. Is required. Therefore, for example, the material of the first resin member in Patent Document 1 is greatly restricted in relation to sealing.

また、挙動調整を行うには、高精度な成形や微細な形状が必要とされるところ、トラスファー成型を行うには高精度な金型が必要となるため、この結果、製造コストが増大し、また、高密度な成形(多数個取り)は困難となる。また、射出成型では成形時における樹脂流れや圧力が比較的大きいことから、受発光素子やその周辺に配置された比較的強度が弱いワイヤボンディングを破壊、変形させてしまう危険が大きい。このため、第一樹脂部材には、成形との関係でも大きな制約が課されることになる。 In addition, high-precision molding and fine shape are required to adjust the behavior, but high-precision mold is required to perform the transfer molding, which results in increased manufacturing cost. In addition, high-density molding (multi-cavity molding) becomes difficult. In addition, in injection molding, since the resin flow and pressure during molding are relatively large, there is a high risk of breaking and deforming the light emitting/receiving element and the wire bonding having relatively weak strength disposed around it. For this reason, great restrictions are imposed on the first resin member in relation to molding.

更に、特許文献1に開示された光電気変換コネクタでは、第一樹脂部材のみを通じて光ファイバと受発光素子の間で光信号が伝達されるから、例えば、第二樹脂部材を利用した挙動調整を行うことはできず、光学設計の観点からも、大きな制約が課されることになる。 Furthermore, in the photoelectric conversion connector disclosed in Patent Document 1, since an optical signal is transmitted between the optical fiber and the light emitting/receiving element only through the first resin member, for example, the behavior adjustment using the second resin member can be performed. This cannot be done, and a large restriction is imposed from the viewpoint of optical design.

このように、第一樹脂部材のみによって受発光素子の封止を行い、また、第一樹脂部材のみによって挙動調整を行い、更に、第一樹脂部材のみを通じて光ファイバと受発光素子との間で光信号による通信を行う、特許文献1の構成では、特に、第一樹脂部材に関して様々な制約が課されることになり、この結果、光電気変換コネクタの設計の自由度が減少することになる。 In this way, the light emitting/receiving element is sealed only by the first resin member, and the behavior is adjusted only by the first resin member, and further, the optical fiber and the light emitting/receiving element are provided only through the first resin member. In the configuration of Patent Document 1 that performs communication by optical signals, various restrictions are imposed particularly on the first resin member, and as a result, the degree of freedom in designing the photoelectric conversion connector is reduced. ..

本願特許発明は、これら従来の問題点を解決するためになされたものであり、光電気変換コネクタの設計の自由度を高めることを目的とする。 The patented invention of the present application has been made in order to solve these conventional problems, and an object thereof is to increase the degree of freedom in the design of the photoelectric conversion connector.

本発明の態様による光電気変換コネクタは、支持体と、該支持体の上に設けられ、光信号を通じて光ファイバと接続され得る光電気変換素子と、を備え、前記光電気変換素子の上部に成形された第一樹脂部材と、前記第一樹脂部材の上部に成形された第二樹脂部材と、前記光電気変換素子と前記光ファイバの間で伝達される光信号が第一樹脂部材と前記第二樹脂部材の双方を通ずる。
本実施形態によれば、光電気変換素子と光ファイバの間で伝達される光信号が、第一樹脂部材と第二樹脂部材といった2種類(以上)の樹脂部材を通ずることから、例えば、第二樹脂部材によって高精度な成形を行い、第一樹脂部材については高精度な加工や微細な形状を不要にする等して、光電気変換コネクタの設計の自由度を高めることができる。
A photoelectric conversion connector according to an aspect of the present invention includes a support and a photoelectric conversion element that is provided on the support and can be connected to an optical fiber through an optical signal. A molded first resin member, a second resin member molded on top of the first resin member, an optical signal transmitted between the photoelectric conversion element and the optical fiber is the first resin member and the Pass through both second resin members.
According to the present embodiment, the optical signal transmitted between the photoelectric conversion element and the optical fiber passes through two types (or more) of resin members such as the first resin member and the second resin member. It is possible to increase the degree of freedom in designing the photoelectric conversion connector by performing high-precision molding with the two resin members and eliminating the need for high-precision processing and fine shape for the first resin member.

上記態様の光電気変換コネクタにおいて、前記光電気変換素子は、前記第一樹脂部材によって封止されてもよい。
本実施形態では、第一樹脂部材と第二樹脂部材といった2種類(以上)の樹脂部材を用いることから、第一樹脂部材については封止に特化させることができる。更に言えば、第一樹脂部材については、例えば、光電気変換素子のような内蔵する半導体を化学的に破壊しないように樹脂材料として不純物イオン含有量を極力抑えた材料を用いることができ、また、射出成型ではなくトランスファー成形を用いることができる。
In the photoelectric conversion connector of the above aspect, the photoelectric conversion element may be sealed by the first resin member.
In the present embodiment, since two types (or more) of resin members such as the first resin member and the second resin member are used, the first resin member can be specialized for sealing. Further speaking, for the first resin member, for example, a resin material having a minimal impurity ion content can be used as a resin material so as not to chemically destroy a built-in semiconductor such as a photoelectric conversion element. Alternatively, transfer molding can be used instead of injection molding.

また、上記態様の光電気変換コネクタにおいて、前記支持体の上に設けられたワイヤボンディングを更に有し、該ワイヤボンディングは、前記光学変換素子とともに前記第一樹脂部材によって封止されてもよい。

The photoelectric conversion connector of the above aspect may further include wire bonding provided on the support, and the wire bonding may be sealed together with the optical conversion element by the first resin member.
When general injection molding is used, the wiring, for example, wire bonding may be deformed by the resin flow and pressure during molding, like the optical conversion element. Since two types (or more) of resin such as a member and a second resin member are used, transfer molding is used for the first resin member instead of injection molding. It can be sealed by the first resin member.

Furthermore, in the photoelectric conversion connector of the above aspect, the refractive index of the first resin member and the refractive index of the second resin member may be different from each other.
In this embodiment, since two types (or more) of resin members such as the first resin member and the second resin member are used, different refractive indexes can be set for the first resin member and the second resin member, The combination of these at least two types of refractive index can increase the degree of freedom in optical design.

また、上記態様の光電気変換コネクタにおいて、前記第二樹脂部材にのみ、又は、前記第一樹脂部材及び前記第二樹脂部材の双方に、前記光信号の光軸を調整する手段を設けてもよい。
本実施形態では、第一樹脂部材と第二樹脂部材といった2種類(以上)の樹脂を用いることから、第一樹脂部材についてはトランスファー成形を用い、第二樹脂部材については射出成型を用いることも可能である。この結果、第二樹脂部材については、高精度な成形や微細な形状に適した射出成型によって、挙動調整手段を形成することが容易となる。また、第一樹脂部材と第二樹脂部材は、共に、成形品であるから、高精度な成形や微細な形状を要求しないのであれば、第一樹脂部材に挙動調整手段を設けることも可能であり、これら少なくとも2種類の挙動調整手段の組み合わせによって、光学設計上の自由度を大きくすることができる。
In the photoelectric conversion connector of the above aspect, a means for adjusting the optical axis of the optical signal may be provided only on the second resin member or on both the first resin member and the second resin member. Good.
In the present embodiment, since two types (or more) of resins such as the first resin member and the second resin member are used, transfer molding may be used for the first resin member and injection molding may be used for the second resin member. It is possible. As a result, it becomes easy to form the behavior adjusting means for the second resin member by highly accurate molding or injection molding suitable for a fine shape. Further, since the first resin member and the second resin member are both molded products, the behavior adjusting means can be provided to the first resin member unless high-precision molding or a fine shape is required. By combining these at least two types of behavior adjusting means, the degree of freedom in optical design can be increased.

The opto-electrical conversion connector 20 can constitute an opto-electrical conversion device by fitting with the electric connector 90.

電気コネクタ90は、樹脂等の絶縁材で形成されたハウジング96と、このハウジング96の底部に設けた端子91を含む。ハウジング96の中央には、光電気変換コネクタ20を嵌合させるための嵌合凹部92が形成されている。端子91の一方の端部側は、基板(図示されていない)に固定される接続部91aとして形成されており、他方の端部は、上部に向って山型に突出した接触部91bとして形成されている。
光電気変換コネクタ20と電気コネクタ90の嵌合時には、電気コネクタ90の端子91の接触部91bと、光電気変換コネクタ20の底部に露出した端子接点68’との接触を通じて、光電気変換装置、更に言えば、これに接続される光ファイバ10(後述する図5)と、基板と、の間で電気信号を通じた通信が行われる。

(For example, a vertical cavity surface emitting (VCSEL) laser type light emitting element). Either may be selected depending on the situation. More specifically, for example, an LED, a semiconductor laser, a photodiode, etc. are included.

支持体68の上には、光電気変換素子69に加え、光電気変換素子69を駆動するための駆動デバイス69aと、例えば、ワイヤボンディングやリード線のような配線69b、その他の配線69cが実装される。尚、ここでいう駆動デバイス69aは、光電気変換素子69が受光素子の場合は、例えば、トランスインピーダンスアンプ/リミッティングアンプ(TIA/LA)を含み、また、光電気変換素子69が発光素子の場合は、例えば、VCSELドライバを含み、いずれの場合であっても、端子接点68’と電気的に接続され得る。電気コネクタと接触する端子接点68’としての複数の端子は支持体68に埋め込まれていてもよい。また、これらの端子は、駆動デバイス69aの一部であってもよい。ワイヤボンディング69bは、例えば、光電気変換素子69を駆動デバイス69aに接続するとともに、駆動デバイス69aを端子やその他の配線69cに接続する導電材として利用される。 On the support 68, in addition to the photoelectric conversion element 69, a drive device 69a for driving the photoelectric conversion element 69, wiring 69b such as wire bonding or lead wire, and other wiring 69c are mounted. To be done. When the photoelectric conversion element 69 is a light receiving element, the driving device 69a includes, for example, a transimpedance amplifier/limiting amplifier (TIA/LA), and the photoelectric conversion element 69 is a light emitting element. In this case, for example, a VCSEL driver may be included, and in any case, the terminal contact 68 ′ may be electrically connected. A plurality of terminals may be embedded in the support body 68 as terminal contacts 68' that contact the electrical connector. Further, these terminals may be a part of the driving device 69a. The wire bonding 69b is used as, for example, a conductive material that connects the photoelectric conversion element 69 to the drive device 69a and also connects the drive device 69a to a terminal or other wiring 69c.

支持体68の上の各素子は、樹脂部材(第一樹脂部材)66によって保護されている。配線69cを除く、光電気変換素子69、駆動デバイス69a、及びワイヤボンディング69bは、樹脂部材66によって完全に封止されるのが好ましい。支持体68の底面には、支持体68に設けた端子接点68’が露出した状態で設けられている。これらの端子接点68’は、例えば、支持体68に設けたビアを通じて、支持体68の表側に配置された配線69cと導通している。 Each element on the support body 68 is protected by a resin member (first resin member) 66. It is preferable that the photoelectric conversion element 69, the driving device 69a, and the wire bonding 69b except the wiring 69c are completely sealed by the resin member 66. On the bottom surface of the support body 68, the terminal contacts 68 ′ provided on the support body 68 are provided in an exposed state. These terminal contacts 68 ′ are electrically connected to the wiring 69 c arranged on the front side of the support 68 through, for example, vias provided in the support 68.

樹脂部材66の上面には、内部に向って突出した窪み66”を設けることによって、光信号の挙動、例えば、光軸を調整することができる凸レンズ66’が形成されている。凸レンズ66’の表面は球面状とされているため、凸レンズ66’は、樹脂部材67の挙動調整手段である、例えば、光軸調整ミラー63と同様に集光機能を有する。これら凸レンズ66’と光軸調整ミラー63は、協働して光信号の挙動、例えば、光軸を調整する手段として機能する。尚、本実施形態では、窪み66”を使用することとしているが、使用態様によっては、窪みの代わりに、外部に向って突出する凸部を設けてもよい。同様に、凸レンズ66’の表面は必ずしも球面とする必要はなく、使用態様によっては、非球面としてもよい。 A convex lens 66′ capable of adjusting the behavior of the optical signal, for example, the optical axis is formed on the upper surface of the resin member 66 by providing a recess 66″ protruding inward. Since the surface is spherical, the convex lens 66' has a light collecting function similar to the behavior adjusting means of the resin member 67, for example, the optical axis adjusting mirror 63. The convex lens 66' and the optical axis adjusting mirror. Reference numeral 63 cooperates to function as a means for adjusting the behavior of the optical signal, for example, the optical axis. In the present embodiment, the recess 66″ is used. In addition, you may provide the convex part which protrudes toward the exterior. Similarly, the surface of the convex lens 66' does not necessarily have to be a spherical surface, and may be an aspherical surface depending on the usage.

図5を参照して、凸レンズ66’と光軸調整ミラー63を用いた光軸調整方法の一例を説明する。
尚、図5の例では、図1等に示したものと異なり、光電気変換コネクタ20を覆うカバー52を示しているが、カバー52は必ずしも必要ではない。カバー52を設ける場合には、心線11の挿入を容易にするため、位置決め溝56と同様に、心線11の挿入側を幅広にし、また、テーパー58の対応部分にテーパー58’を設けるのが好ましい。
An example of the optical axis adjusting method using the convex lens 66′ and the optical axis adjusting mirror 63 will be described with reference to FIG.
In the example of FIG. 5, unlike the one shown in FIG. 1 and the like, the cover 52 that covers the photoelectric conversion connector 20 is shown, but the cover 52 is not always necessary. When the cover 52 is provided, in order to facilitate the insertion of the core wire 11, the insertion side of the core wire 11 is widened, and the taper 58′ is provided at the corresponding portion of the taper 58, similarly to the positioning groove 56. Is preferred.

光電気変換コネクタ20に設置された光ファイバ10は、一般に使用されているものと同様のものと考えてよい。即ち、中心にコア12とクラッド13から成る心線11を有し、更に、心線11の外周を覆う被覆14を有する。光ファイバ10はマルチモードファイバであるのが好ましく、材質はプラスチックであってもよいし、石英であってもよい。光ファイバ10から電気コネクタの端子への信号の伝達は、以下の手順で行われる。
心線11の先端11’から射出された光信号は、光軸61として示されているように、先ず、進行方向において多少拡がりつつ、心線11の先端11’に対向して配置された界面(受光面)57を通じて反射部60に取り込まれる。反射部60に取り込まれた光信号は、樹脂部材67に形成された光軸調整ミラー63によって、略直角に方向変換されるとともに、凸レンズ66’へ向けて集光される。凸レンズ66’によって集光された光信号は、その後、光電気変換素子69へ入射する。入射した光信号は、光電気変換素子69で電気信号に変換された後、電気コネクタの端子と光電気変換コネクタ20の支持体68の底部に露出した端子接点68’との接触を通じて、外部に取り出される。尚、反射部60の界面57は、光ファイバ10からの光の進行方向(図示矢印「A」))に対して鋭角又は鈍角に設定されているため、光ファイバ10に対する、界面57からの反射戻り光を減少させることができる。
The optical fiber 10 installed in the photoelectric conversion connector 20 may be considered to be the same as the one generally used. That is, the core wire 11 including the core 12 and the clad 13 is provided at the center, and the coating 14 covering the outer circumference of the core wire 11 is further provided. The optical fiber 10 is preferably a multimode fiber, and the material thereof may be plastic or quartz. The signal transmission from the optical fiber 10 to the terminals of the electrical connector is performed by the following procedure.
The optical signal emitted from the tip 11 ′ of the core wire 11 is, as shown by the optical axis 61, first spread a little in the traveling direction, and is an interface arranged facing the tip 11 ′ of the core wire 11. The light is received by the reflection unit 60 through the (light receiving surface) 57. The optical signal taken into the reflecting portion 60 is converted into a direction at a substantially right angle by the optical axis adjusting mirror 63 formed on the resin member 67 and is condensed toward the convex lens 66′. The optical signal collected by the convex lens 66′ then enters the photoelectric conversion element 69. The incident optical signal is converted into an electric signal by the photoelectric conversion element 69, and then is externally exposed through contact between the terminal of the electric connector and the terminal contact 68′ exposed at the bottom of the support 68 of the photoelectric conversion connector 20. Taken out. Since the interface 57 of the reflecting portion 60 is set to an acute angle or an obtuse angle with respect to the traveling direction of the light from the optical fiber 10 (arrow "A" in the drawing), the reflection from the interface 57 to the optical fiber 10 is reflected. The return light can be reduced.

逆に、電気コネクタの端子から光電気変換コネクタ20に設置された光ファイバ10への信号の伝達は、上とは逆の手順で行われる。
電気コネクタの端子と、光電気変換コネクタ20の支持体68の底部に露出した端子接点68’と、の接触を通じて取り込まれた電気信号は、光軸61として示されているように、先ず、光電気変換素子69を通じて光信号に変換された後、進行方向において多少拡がりつつ、光電気変換素子69に対向して配置された凸レンズ66’へ案内される。その後、凸レンズ66’の界面(発光面)を通じて光軸調整ミラー63へ向けて集光される。その後、光信号は、樹脂部材67に形成された光軸調整ミラー63によって、略直角に方向変換されるとともに、界面57に向けて集光され、界面57を通過した後に、界面57に対向配置された心線11の先端11’から光ファイバ10へと伝達される。尚、凸レンズ66’の界面は、湾曲を伴うものではるものの、反射部60の界面57と同様に、全体としては光電気変換素子69からの光の進行方向(図示矢印「B」)に対して鋭角又は鈍角に設定されていることから、光電気変換素子69に対する、界面からの反射戻り光を減少させることができる。
On the contrary, the transmission of the signal from the terminal of the electric connector to the optical fiber 10 installed in the photoelectric conversion connector 20 is performed by the reverse procedure to the above.
The electrical signal captured through the contact between the terminal of the electrical connector and the terminal contact 68 ′ exposed at the bottom of the support 68 of the opto-electrical conversion connector 20 is, as shown by the optical axis 61, first, the optical signal. After being converted into an optical signal through the electrical conversion element 69, it is guided to a convex lens 66 ′ arranged facing the photoelectric conversion element 69 while expanding a little in the traveling direction. Then, the light is focused toward the optical axis adjusting mirror 63 through the interface (light emitting surface) of the convex lens 66'. After that, the optical signal is redirected at a substantially right angle by the optical axis adjusting mirror 63 formed on the resin member 67, is condensed toward the interface 57, passes through the interface 57, and then is arranged facing the interface 57. It is transmitted to the optical fiber 10 from the end 11 ′ of the core wire 11 thus cut. Although the interface of the convex lens 66' is accompanied by a curve, like the interface 57 of the reflecting portion 60, the interface with respect to the traveling direction of the light from the photoelectric conversion element 69 (the arrow "B" in the figure) as a whole. Since it is set to an acute angle or an obtuse angle, it is possible to reduce the reflected return light from the interface with respect to the photoelectric conversion element 69.

このように、本実施形態によれば、樹脂部材66の凸レンズ66’や樹脂部材67の光軸調整ミラー63といった、複数の光軸調整手段が設けられていることから、これらの手段に集光、屈折、反射といった光学的な機能を持たせて、光学設計の自由度を高めることができる。 As described above, according to the present embodiment, since a plurality of optical axis adjusting means such as the convex lens 66 ′ of the resin member 66 and the optical axis adjusting mirror 63 of the resin member 67 are provided, these means are used for focusing. It is possible to increase the degree of freedom in optical design by providing optical functions such as refraction and reflection.

また、光電気変換素子69と光ファイバ10の間で伝達される光信号が、樹脂部材66と樹脂部材67といった2種類(以上)の樹脂部材を通ずることから、例えば、樹脂部材67によって高精度な成形を行い、樹脂部材66については高精度な加工や微細な形状を不要にする等して、光電気変換コネクタの設計の自由度を高めることができる。 Further, since the optical signal transmitted between the photoelectric conversion element 69 and the optical fiber 10 passes through two types (or more) of resin members such as the resin member 66 and the resin member 67, for example, the resin member 67 provides high accuracy. It is possible to increase the degree of freedom in designing the opto-electrical conversion connector by performing various moldings and eliminating the need for highly accurate processing and fine shape for the resin member 66.

上に説明した光電気変換コネクタは、例えば、以下の方法で製造することができる。
1. 先ず、支持体68を準備する。支持体68の上には、光電気変換素子69に加え、駆動デバイス69a、ワイヤボンディング69b、その他の配線69cが含まれる。
2. 次に、これらの素子の上部を樹脂部材(第一樹脂部材)66によって成形、好ましくは一体成形する。
3. 最後に、樹脂部材66の上部を樹脂部材(第二樹脂部材)67によって成形、好ましくは一体成形する。
The photoelectric conversion connector described above can be manufactured, for example, by the following method.
1. First, the support 68 is prepared. On the support 68, in addition to the photoelectric conversion element 69, a drive device 69a, wire bonding 69b, and other wiring 69c are included.
2. Next, the upper portions of these elements are molded with a resin member (first resin member) 66, preferably integrally molded.
3. Finally, the upper portion of the resin member 66 is molded by the resin member (second resin member) 67, preferably integrally molded.

ここで樹脂部材66による成形は、支持体68の上の素子に直接的に行われてもよいし、例えば、空気層を介して間接的に行われてもよい。また、樹脂部材67による成形も、樹脂部材66に対して直接的に行われてもよいし、他の層(図示されていない)を介して間接的に行われてもよい。
但し、光電気変換素子69やワイヤボンディング69b(更に、ワイヤボンディング69bの周辺に位置する駆動デバイス69a)については、直接的な成形によって完全に封止するのが好ましい。換言すれば、樹脂部材(第一樹脂部材)66については封止に特化させるのが好ましい。封止に特化させることにより、樹脂部材66については、光電気変換素子69のような内蔵する半導体を化学的に破壊しないよう樹脂材料として不純物イオン含有量を極力抑えた材料を用いることができる。
Here, the molding with the resin member 66 may be performed directly on the element on the support body 68, or may be performed indirectly, for example, via an air layer. Further, the molding with the resin member 67 may be performed directly on the resin member 66, or may be performed indirectly via another layer (not shown).
However, it is preferable that the photoelectric conversion element 69 and the wire bonding 69b (further, the drive device 69a located around the wire bonding 69b) be completely sealed by direct molding. In other words, the resin member (first resin member) 66 is preferably specialized for sealing. By specializing in sealing, as the resin member 66, it is possible to use a material whose impurity ion content is suppressed as much as possible as a resin material so as not to chemically destroy a built-in semiconductor such as the photoelectric conversion element 69. ..

また、封止のために一般の射出成型を用いた場合には、例えば、ワイヤボンディングのような配線69bを、成形時の樹脂流れや圧力によって変形させてしまう危険があるが、樹脂部材66についてはトランスファー成形を用いることとして、そのような問題を解消することもできる。 Further, when general injection molding is used for sealing, for example, there is a risk that the wiring 69b such as wire bonding may be deformed by the resin flow or pressure during molding. It is possible to solve such a problem by using transfer molding.

このように、樹脂部材66と樹脂部材67といった2種類(以上)の樹脂部材を用いて成形を行うことにより、光電気変換コネクタの設計の自由度は飛躍的に向上することになる。
例えば、樹脂部材66についてはトランスファー成形を用い、樹脂部材67については射出成型を用いることにより、樹脂部材67については、高精度な成形や微細な形状に適した射出成型によって挙動調整手段を形成することができる。ここで樹脂部材66のトランスファー成形には、例えば、透明熱硬化性エポキシや透明シリコーン樹脂を、一方、樹脂部材67の射出成形には、例えば、透明な熱可塑性樹脂である、ポリエーテルイミドやポリカーボネートを、それぞれ用いることができる。尚、ここでの「透明」は、伝達される光信号の波長との関係において透明であれば足り、人間の視覚の上では着色されているようなものであってもよい。従って、樹脂部材66及び樹脂部材67は透明であることは要するものの、それらに着色することもできる。
As described above, by performing molding using two types (or more) of resin members such as the resin member 66 and the resin member 67, the degree of freedom in designing the photoelectric conversion connector is dramatically improved.
For example, by using transfer molding for the resin member 66 and injection molding for the resin member 67, the behavior adjusting means is formed for the resin member 67 by highly accurate molding or injection molding suitable for a fine shape. be able to. Here, for example, transparent thermosetting epoxy or transparent silicone resin is used for transfer molding of the resin member 66, while polyetherimide or polycarbonate, which is a transparent thermoplastic resin, is used for injection molding of the resin member 67. Can be used respectively. The “transparent” here is sufficient if it is transparent in relation to the wavelength of the transmitted optical signal, and may be colored in terms of human vision. Therefore, although the resin member 66 and the resin member 67 need to be transparent, they can be colored.

また、樹脂部材66と樹脂部材67といった2種類(以上)の樹脂部材を用いて成形を行うことにより、樹脂部材66については樹脂部材67よりも硬化時間の長い部材を選択して、樹脂部材67については、成形時に高密度化(多数個取り)を図ることで製造時の工程時間のバランスをとることができる。
更に、樹脂部材66と樹脂部材67に、互いに異なる屈折率を設定して、これら少なくとも2種類の屈折率の組み合わせにより、光学設計の自由度を向上させることができる。
Further, by molding using two kinds (or more) of resin members such as the resin member 66 and the resin member 67, a member having a longer curing time than the resin member 67 is selected for the resin member 66, and the resin member 67 is selected. With regard to (2), the process time at the time of manufacturing can be balanced by increasing the density (multi-cavity production) at the time of molding.
Further, the resin member 66 and the resin member 67 can be set to have different refractive indexes, and a combination of these at least two kinds of refractive indexes can improve the degree of freedom in optical design.

尚、樹脂部材66と樹脂部材67はいずれも、ジェル等の不定形のものではなく、所定の硬度を有した成形品であるから、これらの双方に挙動調整手段を設けることができる。この結果、これら少なくとも2種類の挙動調整手段の組み合わせによって、光学設計上の自由度を向上させることができる。但し、樹脂部材67に高精度な成形や微細な形状を設けることができるのであれば、必ずしも樹脂部材66に挙動調整手段を設ける必要はない。 It should be noted that both the resin member 66 and the resin member 67 are molded articles having a predetermined hardness, not an indefinite shape such as gel, so that behavior adjusting means can be provided for both of them. As a result, the degree of freedom in optical design can be improved by combining these at least two types of behavior adjusting means. However, if the resin member 67 can be formed with high precision molding or a fine shape, it is not always necessary to provide the behavior adjusting means on the resin member 66.

図6に、挙動調整手段の変形例を示す。ここでは、樹脂部材66の上面に、凸レンズ66’の代わりに平坦な傾斜面70が形成されている。光軸61’として示されているように、この場合、傾斜面70は凸レンズ66’のような集光機能は有しないが、凸レンズ66’と同様に、光電気変換素子69からの光の進行方向(図示矢印「B」)に対して鋭角又は鈍角に設定されていることから、これによって、光電気変換素子69に対する、受光面からの反射戻り光を減少させることができる。 FIG. 6 shows a modification of the behavior adjusting means. Here, a flat inclined surface 70 is formed on the upper surface of the resin member 66 instead of the convex lens 66'. As shown by the optical axis 61′, in this case, the inclined surface 70 does not have the light condensing function like the convex lens 66′, but the light from the photoelectric conversion element 69 travels similarly to the convex lens 66′. Since the angle is set to an acute angle or an obtuse angle with respect to the direction (arrow "B" in the drawing), this can reduce the reflected return light from the light receiving surface with respect to the photoelectric conversion element 69.

尚、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、上に示した好ましい一つの実施形態では、樹脂部材66の材質等と樹脂部材67の材質等は互いに異なるものとして説明したが、例えば、樹脂部材66、67を別々の成形過程で製造したことによって屈折率の相異や成分の相異が生ずるのであれば、それらの材質等は同じであってもよい。
従って、ここに開示された実施形態は例示であって制限的なものではなく、本発明の範囲は上記した説明ではなく特許請求の範囲によって定められるべきであり、特許請求の範囲と均等の意味及び範囲内での全ての変更が含まれる。
It should be noted that the present invention is not limited to the above-described embodiment, and various other modifications are possible. For example, in the above-described preferred embodiment, the material of the resin member 66 and the material of the resin member 67 are different from each other. However, for example, the resin members 66 and 67 are manufactured in different molding processes. The materials may be the same as long as the difference in the refractive index or the difference in the component is thereby caused.
Therefore, the embodiments disclosed herein are illustrative and not restrictive, and the scope of the present invention should be defined not by the above description but by the scope of the claims, and the meaning equivalent to the scope of the claims. And all changes within the scope are included.
