Description

本発明は、回路基板上に配され、複数の端子板を有しており、カメラモジュール等の外部機器と回路基板とを電気的に接続する多極コネクタに関するものである。 The present invention relates to a multipolar connector that is arranged on a circuit board, has a plurality of terminal boards, and electrically connects an external device such as a camera module and the circuit board.

従来、特許文献１に記載されるように、回路基板上に多極コネクタを設けて、この多極コネクタにカメラモジュール等の外部機器を挿入することで、外部機器を回路基板上に実装する方法が知られている。この多極コネクタは、樹脂により形成されたハウジングに、外部機器の端子部と当接する当接部を有する複数の端子板を組み付けたものである。このハウジングにより形成された空間に外部機器が挿入されると、空間に露出している複数の端子板のそれぞれの当接部が該外部機器の端子部に押し込まれて、各端子板のハウジングに固定された部分から当接部までが撓み、この状態で外部機器が多極コネクタに固定される。このとき、この多極コネクタの各端子板が撓んでいることで、各端子板の当接部が外部機器の端子部に押し当てる力が発生しており、この力により外部機器の端子部と各端子板の当接部との接触信頼性を確保している。
特開２００４−６３７８７号公報 Conventionally, as described in Patent Document 1, a method of mounting an external device on a circuit board by providing a multi-pole connector on a circuit board and inserting an external device such as a camera module into the multi-pole connector. It has been known. This multipolar connector is obtained by assembling a plurality of terminal plates having an abutting portion that abuts against a terminal portion of an external device on a housing formed of resin. When an external device is inserted into the space formed by the housing, the contact portions of the plurality of terminal plates exposed in the space are pushed into the terminal portions of the external device, and are inserted into the housings of the terminal plates. From the fixed portion to the contact portion bends, and in this state, the external device is fixed to the multipolar connector. At this time, since each terminal plate of this multipolar connector is bent, a force that the contact portion of each terminal plate presses against the terminal portion of the external device is generated. The contact reliability with the contact part of each terminal board is ensured.
JP 2004-63787 A

しかしながら、上記のような従来の多極コネクタにおいては、例えば多極コネクタの小型化を図るために、端子板を小型化して、当接部からハウジングに固定される部分までの寸法を短くすると、外部機器をハウジングの空間に挿入した時に端子板が塑性変形してしまうことがある。端子板が塑性変形してしまうと、外部機器の端子部に各端子板の当接部を押し当てる力が弱くなり、接触信頼性が損なわれて外部機器と回路基板との接続不良が発生する。よって、端子板を塑性変形しないような大きさや形状に設計しなければならないため、多極コネクタの設計上の自由度が制約され、多極コネクタの小型化も困難である。多極コネクタを小型化しつつ端子板の塑性変形を防ぐためには、端子板の形状が複雑なものとなるため、多極コネクタをハウジングと端子板を一体にしてインサート成形により製造することができなくなる。インサート成形ができなければ、端子板はハウジングが成形された後に組み付ける必要があり、多極コネクタの製造に手間がかかり製造コストが大きくなってしまう。 However, in the conventional multipolar connector as described above, for example, in order to reduce the size of the multipolar connector, if the terminal plate is reduced in size and the dimension from the contact portion to the portion fixed to the housing is shortened, When an external device is inserted into the space of the housing, the terminal board may be plastically deformed. If the terminal plate is plastically deformed, the force that presses the contact portion of each terminal plate against the terminal portion of the external device becomes weak, the contact reliability is impaired, and poor connection between the external device and the circuit board occurs. . Therefore, since the terminal plate must be designed in such a size and shape as not to be plastically deformed, the degree of freedom in designing the multipolar connector is restricted, and it is difficult to reduce the size of the multipolar connector. In order to prevent the plastic deformation of the terminal plate while reducing the size of the multi-pole connector, the shape of the terminal plate becomes complicated, so the multi-pole connector cannot be manufactured by insert molding with the housing and the terminal plate integrated. . If insert molding is not possible, it is necessary to assemble the terminal board after the housing is molded, which requires time and labor for manufacturing the multipolar connector and increases the manufacturing cost.

本発明は、上記問題点を鑑みてなされたものであり、端子板に樹脂バネ部を被着させて構成することにより、端子板を小型化、単純形状化したときにも外部機器の端子部に端子板の当接部を押し当てる力を確実に得て、外部機器と回路基板等を確実に電気的に接続させることができる多極コネクタを提供することを目的とする。 The present invention has been made in view of the above problems, and is configured by attaching a resin spring portion to a terminal plate, so that the terminal portion of an external device can be formed even when the terminal plate is downsized and simplified. An object of the present invention is to provide a multipolar connector capable of reliably obtaining a force for pressing the contact portion of the terminal plate against the external device and reliably connecting an external device to a circuit board or the like.

A plurality of terminal plates configured to have a resin spring portion supported by the housing, which is attached to the other surface of the plurality of terminal plates on which the contact portion is provided. The external device is inserted into the space of the housing. When the contact portion of each terminal plate is pushed into the terminal portion of the external device and the terminal plate and the resin spring portion are bent together, the contact portion of each terminal plate is connected to the terminal of the external device. It generates force to press against the part.

請求項２の発明は、請求項１の発明において、前記ハウジング及び樹脂バネ部が、前記複数の端子板を金型にインサートした状態で、各端子板に対する樹脂バネ部同士が互いに独立するように樹脂により一体成形されているものである。 According to a second aspect of the present invention, in the first aspect of the invention, the housing and the resin spring portion are arranged such that the resin spring portions for each terminal plate are independent from each other in a state where the plurality of terminal plates are inserted into a mold. It is integrally molded with resin.

請求項３の発明は、請求項１又は請求項２の発明において、前記樹脂バネ部は、前記複数の端子板の前記当接部が設けられた面とは他面を、外部の回路基板に露出しないように被覆するように被着されているものである。 According to a third aspect of the present invention, in the first or second aspect of the present invention, the resin spring portion is provided on an external circuit board with a surface other than the surface on which the contact portions of the plurality of terminal plates are provided. It is attached so as not to be exposed.

請求項１の発明によれば、各端子板の当接部が設けられた面とは他面に樹脂バネ部を被着させ、各端子板と樹脂バネ部がともに撓むようにしたので、端子板を小型化しても外部機器の端子部に端子板の当接部を確実に押し当てることができ、設計上の自由度を高めるとともに外部機器と回路基板等とを確実に電気的に接続させることが可能となる。 According to the invention of claim 1, since the resin spring portion is attached to the other surface of the surface where the contact portion of each terminal plate is provided, each terminal plate and the resin spring portion are bent together. Even if the device is downsized, the terminal plate abutment part can be reliably pressed against the terminal part of the external device, increasing the degree of freedom in design and ensuring that the external device and the circuit board are electrically connected.

請求項２の発明によれば、各端子板を金型にインサートした状態で、各端子板に対する樹脂バネ部同士が互いに独立するように樹脂により一体成形するので、各端子板をハウジング成形後に組み付ける工程が不要となって多極コネクタの製造コストを安価なものとして容易に製造することが可能となり、また、各端子板の撓み量が異なるときにも、各端子板の当接部を外部機器の端子部に押し当てる力が確実に発生して外部機器と回路基板等をより確実に電気的に接続させることが可能となる。 According to the second aspect of the present invention, since the terminal springs are integrally molded with the resin so that the resin spring portions with respect to the terminal boards are independent from each other with the terminal boards inserted in the mold, the terminal boards are assembled after the molding of the housing. This eliminates the need for a process and makes it easy to manufacture multi-pole connectors at a low cost. Even when the amount of bending of each terminal plate differs, the contact portion of each terminal plate can be connected to an external device. Thus, it is possible to surely generate a force to press against the terminal portion, and to more reliably electrically connect the external device and the circuit board.

請求項３の発明によれば、各端子板の当接部が設けられた面とは他面が外部の回路基板に露出しないように樹脂バネ部によって被覆されるので、外部機器が挿入されて各端子板が外部の回路基板に向けて撓んだときにも各端子板と回路基板とが接触することがなくなり、他に接触防止のための部材を追加するなど設計上の制約を増やすことなく、端子板と回路基板とが電気的に短絡されてしまう等のトラブルを容易に防ぐことが可能となる。 According to the invention of claim 3, since the other surface is covered with the resin spring portion so that the other surface is not exposed to the external circuit board, the external device is inserted. Even when each terminal board is bent toward the external circuit board, each terminal board and the circuit board will not be in contact with each other, and design restrictions such as adding other members to prevent contact will be increased. Therefore, it is possible to easily prevent troubles such as an electrical short circuit between the terminal board and the circuit board.

以下、本発明の実施の形態について図面を参照して説明する。図１乃至図４は、本発明の実施形態に係る多極コネクタを示す。この多極コネクタは、上方が開口した空間１ａを中央部に形成している樹脂製のハウジング１と、このハウジング１に、ハウジング１の外部及び空間１ａに露出する状態で１０個ずつ対向するように埋め込まれて保持された端子板２と、各端子板２の下側にそれぞれ被着された２０個の樹脂バネ部３と、ハウジング１の側面及び上面を略覆うように設けられた板金からなるシールド４を備えたものである。この多極コネクタは、回路基板（図示なし）上に配されるものであり、外部機器の一例であり、下面に端子部５ｂを有するカメラモジュール５が図１の矢印方向に挿入され、図２に示されるように、このカメラモジュール５を保持するものである。後述するように、この多極コネクタのハウジング１と樹脂バネ部３は、端子板２を金型にインサートした状態で樹脂により一体成形されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show a multipolar connector according to an embodiment of the present invention. This multipolar connector is configured to face the housing 1 made of a resin having a space 1a that is open at the center at the center, and 10 each in a state of being exposed to the outside of the housing 1 and the space 1a. Terminal plate 2 embedded and held, 20 resin spring portions 3 respectively attached to the lower side of each terminal plate 2, and a sheet metal provided so as to substantially cover the side surface and the upper surface of the housing 1 The shield 4 is provided. This multipolar connector is arranged on a circuit board (not shown) and is an example of an external device. A camera module 5 having a terminal portion 5b on the lower surface is inserted in the direction of the arrow in FIG. As shown in FIG. 4, the camera module 5 is held. As will be described later, the housing 1 and the resin spring portion 3 of this multipolar connector are integrally formed of resin with the terminal plate 2 inserted in a mold.

ハウジング１上面の空間１ａの開口部の近傍には係止爪１ｂが形成されており、空間１ａにカメラモジュール５が挿入された後、カメラモジュール５がハウジング１から簡単には脱落しないように係止する。また、係止爪１ｂと同様にハウジング１の上面にはカメラモジュール５を空間１ａに導入するためのガイド１ｃが形成されており、カメラモジュール５の挿入が容易に行うことができるようにされている。空間１ａの下方中央部の、対向して配された１０個ずつの端子板２の間にはハウジング１の剛性を確保するための梁状部１ｄが形成されている。 A locking claw 1b is formed in the vicinity of the opening of the space 1a on the upper surface of the housing 1 so that the camera module 5 is not easily detached from the housing 1 after the camera module 5 is inserted into the space 1a. Stop. Similarly to the locking claw 1b, a guide 1c for introducing the camera module 5 into the space 1a is formed on the upper surface of the housing 1, so that the camera module 5 can be easily inserted. Yes. A beam-shaped portion 1d for ensuring the rigidity of the housing 1 is formed between the ten terminal plates 2 arranged opposite to each other at the lower central portion of the space 1a.

各端子板２は、ハウジング１の外部に露出した部位が回路接続部２ａとされており、この多極コネクタが回路基板上に配されたときに回路基板上の回路に接続される。各端子板２は、空間１ａに露出した側よりもこの回路接続部２ａの側のほうが短くなるようにして、つまり回路接続部２ａの近傍でハウジング１に保持されるようにインサート成形によりハウジング１に埋め込まれている。各端子板２の空間１ａに露出した側の端部近傍の上面には、他の部分よりも上方に盛り上がるように曲げられて形成された当接部２ｂが設けられており、この当接部２ｂは、空間１ａにカメラモジュール５が挿入されたときに、カメラモジュール５の端子部５ａと当接するような位置となるように配されている。各端子板２の当接部２ｂが設けられた部分からハウジング１に保持された部分は可撓性を有する梁状の可撓部とされており、この部分が撓むことで当接部２ｂが上下方向に変位可能とされている。 Each terminal plate 2 has a circuit connection portion 2a at a portion exposed to the outside of the housing 1, and is connected to a circuit on the circuit board when this multipolar connector is arranged on the circuit board. Each terminal plate 2 is formed by insert molding so that the side of the circuit connection portion 2a is shorter than the side exposed to the space 1a, that is, is held by the housing 1 in the vicinity of the circuit connection portion 2a. Embedded in. On the upper surface in the vicinity of the end portion of each terminal board 2 exposed to the space 1a, a contact portion 2b formed so as to rise above the other portion is provided. 2b is arranged so as to come into contact with the terminal portion 5a of the camera module 5 when the camera module 5 is inserted into the space 1a. A portion of each terminal plate 2 that is held by the housing 1 from a portion where the contact portion 2b is provided is a flexible beam-shaped flexible portion, and the contact portion 2b is bent by this portion being bent. Can be displaced in the vertical direction.

各樹脂バネ部３は、上述のようにインサート成形の際にハウジング１とともに一体成形されており、それぞれ端子板２の当接部２ｂが設けられた面とは他面の可撓部に被着するように成形される。樹脂バネ部３は、ハウジング１の各端子板２が保持される部分と一体に繋がることで、ハウジング１に保持されるように成形されており、端子板２の可撓部が撓むとそれとともに撓むようになっている。この樹脂バネ部３は、多極コネクタが回路基板上に配されたときに回路基板側に面する端子板２の面を被覆するようにされている。本実施形態においては、各樹脂バネ部３は、互いに独立するように設けられており、また、例えば端子板２の厚みの３倍程度の厚みに形成されている。 Each resin spring portion 3 is integrally formed with the housing 1 at the time of insert molding as described above, and is attached to the flexible portion on the other side of the surface on which the contact portion 2b of the terminal plate 2 is provided. To be molded. The resin spring portion 3 is formed so as to be held by the housing 1 by being integrally connected to a portion where each terminal plate 2 of the housing 1 is held. When the flexible portion of the terminal plate 2 is bent, the resin spring portion 3 is formed. It comes to bend. The resin spring portion 3 covers the surface of the terminal board 2 facing the circuit board when the multipolar connector is disposed on the circuit board. In the present embodiment, the resin spring portions 3 are provided so as to be independent from each other, and are formed to have a thickness of about three times the thickness of the terminal plate 2, for example.

そして、各樹脂バネ部３は、ハウジング１の梁状部１ｄとも一体に繋がるようにして延設されて成形されている。この延設された部分は、図４に示されるように、各樹脂バネ部３の当接部２ｂの下側近傍から、中央側の梁状部１ｄに向かって折れ曲がってＶ字状となるように成形されており、この延設された部分の３箇所の折れ曲がった部分は薄肉部３ａとされている。薄肉部３ａの厚みは、樹脂の材質や延設された部分の形状等により適宜設定されるものである。 Each resin spring portion 3 is extended and molded so as to be integrally connected to the beam-like portion 1 d of the housing 1. As shown in FIG. 4, the extended portion is bent from the vicinity of the lower side of the contact portion 2b of each resin spring portion 3 toward the central beam-like portion 1d so as to be V-shaped. The three bent portions of the extended portion are thin-walled portions 3a. The thickness of the thin portion 3a is appropriately set depending on the material of the resin, the shape of the extended portion, and the like.

シールド４は、板金により予め成形されたものであり、ハウジング１に被せて係止される。シールド４の下縁の一部には接地部４ａが設けられており、この多極コネクタが回路基板上に配されたときに回路基板上の接地電位に接続される。このシールド４を設けることにより、多極コネクタに外部からのノイズや静電気が影響しないようにし、カメラモジュール５や回路基板上に設けられる回路等の誤動作や破壊を防いでいる。 The shield 4 is formed in advance by sheet metal and is locked on the housing 1. A ground portion 4a is provided at a part of the lower edge of the shield 4 and is connected to the ground potential on the circuit board when the multipolar connector is arranged on the circuit board. By providing this shield 4, noise and static electricity from the outside are not affected on the multipolar connector, and malfunctions and destruction of circuits provided on the camera module 5 and the circuit board are prevented.

図５は、この多極コネクタのハウジング１の空間１ａにカメラモジュール５が挿入されたときの端子板２及び樹脂バネ部３の変形した様子を示す。カメラモジュール５が挿入されていないときの端子板２及び樹脂バネ部３は撓んでいない自然状態であり、図４に示されるように当接部２ｂが空間１ａの上側に突出するように構成されている。カメラモジュール５が空間１ａに挿入されると、各端子板２の当接部２ｂはカメラモジュール５の端子部５ａと当接して下方に押し込まれ、各端子板２の可撓部と樹脂バネ部３が下方に撓む。このとき、この各端子板２の可撓部と樹脂バネ部３には自然状態への復元力が発生しており、この復元力により、各端子板２の当接部２ｂがカメラモジュール５の端子部５ａに押し当てられ、当接部２とこの端子部５ａとを電気的に接続させている。この復元力はこの多極コネクタに振動等の外部力が加わったときにも、当接部２ｂと端子部５ａとが離れたりすることがないように十分な強さとされている。 FIG. 5 shows a state in which the terminal plate 2 and the resin spring portion 3 are deformed when the camera module 5 is inserted into the space 1a of the housing 1 of the multipolar connector. When the camera module 5 is not inserted, the terminal plate 2 and the resin spring portion 3 are in a natural state where they are not bent, and as shown in FIG. 4, the contact portion 2b protrudes above the space 1a. ing. When the camera module 5 is inserted into the space 1a, the contact portion 2b of each terminal plate 2 contacts the terminal portion 5a of the camera module 5 and is pushed downward, and the flexible portion and the resin spring portion of each terminal plate 2 are inserted. 3 bends downward. At this time, a restoring force to the natural state is generated in the flexible portion and the resin spring portion 3 of each terminal plate 2, and by this restoring force, the contact portion 2 b of each terminal plate 2 is in the camera module 5. The contact portion 2 and the terminal portion 5a are electrically connected by being pressed against the terminal portion 5a. The restoring force is sufficiently strong so that the contact portion 2b and the terminal portion 5a are not separated even when an external force such as vibration is applied to the multipolar connector.

このとき、樹脂バネ部３の、ハウジング１の梁状部１ｄと一体に繋がるように延設された部分は、上述のように各端子板２の可撓部と樹脂バネ部３が撓むことを妨げることがない。上述のように各端子板２の可撓部と樹脂バネ部３が撓むと、樹脂バネ部３の薄肉部３ａはヒンジ状に大きく変形する。この薄肉部３ａが大きく変形して、樹脂バネ部３の延設された部分の３箇所の折れ曲がった部分が開いたり畳まれたりすることで、端子板２の当接部２ｂ付近の部分とハウジング１の梁状部１ｄと繋がった部分との距離が変わり、当接部２ｂが変位可能となるようにされている。 At this time, the portion of the resin spring portion 3 extending so as to be integrally connected to the beam-like portion 1d of the housing 1 is bent by the flexible portion of each terminal plate 2 and the resin spring portion 3 as described above. Will not be disturbed. As described above, when the flexible portion of each terminal plate 2 and the resin spring portion 3 are bent, the thin portion 3a of the resin spring portion 3 is greatly deformed into a hinge shape. The thin portion 3a is greatly deformed, and the three bent portions of the extended portion of the resin spring portion 3 are opened or folded, so that the portion near the contact portion 2b of the terminal plate 2 and the housing The distance from the portion connected to the first beam-like portion 1d changes so that the contact portion 2b can be displaced.

各端子板２の当接部２ｂが設けられた面とは他面に樹脂バネ部３が被着され、各端子板２の可撓部と樹脂バネ部３とがともに撓むようにされているので、本実施形態のように各端子板２が小型で単純形状であったとしても可撓部が撓むときに塑性変形せず、又は塑性変形した場合にも樹脂バネ部３の復元力が働くことによって、当接部２ｂと端子部５ａとを確実に電気的に接続させることが可能となる。そして、端子板２を小型化したり単純形状とすると、上述のようにインサート成形によりハウジング１、端子板２、樹脂バネ部３を一体成形することが可能となり、各端子板２をハウジング１に組み付ける工程が不要となって、多極コネクタの製造コストが安価となるとともに容易に製造することが可能となる。また、各端子板２に対する樹脂バネ部３同士が互いに独立するように成形されるので、各端子板２の撓み量が異なるときにも、各端子板２の当接部２ｂを端子部５ａに押し当てる力が確実に発生して、各端子板２の当接部２ｂと端子部５ａとの接触安定性が向上する。 Since the resin spring part 3 is attached to the other side of the surface on which the contact part 2b of each terminal plate 2 is provided, the flexible part of each terminal plate 2 and the resin spring part 3 are both bent. Even if each terminal board 2 is small and has a simple shape as in this embodiment, the plastic spring portion 3 does not plastically deform when the flexible portion bends, or the restoring force of the resin spring portion 3 works even when plastically deformed. This makes it possible to reliably connect the contact portion 2b and the terminal portion 5a. If the terminal plate 2 is downsized or has a simple shape, the housing 1, the terminal plate 2, and the resin spring portion 3 can be integrally formed by insert molding as described above, and each terminal plate 2 is assembled to the housing 1. A process is not required, and the manufacturing cost of the multipolar connector is reduced and can be easily manufactured. Further, since the resin spring portions 3 for the respective terminal plates 2 are formed so as to be independent from each other, even when the bending amount of each terminal plate 2 is different, the contact portion 2b of each terminal plate 2 is changed to the terminal portion 5a. The pressing force is surely generated, and the contact stability between the contact portion 2b of each terminal plate 2 and the terminal portion 5a is improved.

また、多極コネクタが回路基板上に配されたときに回路基板側に面する端子板２の面が樹脂バネ部３により被覆されているので、カメラモジュール５が挿入されて各端子板２が外部の回路基板に向けて撓んだときにも各端子板２と回路基板とが接触することがなくなり、他に接触防止のための部材を追加するなど設計上の制約を増やすことなく、端子板２と回路基板とが電気的に短絡されてしまう等のトラブルを容易に防ぐことが可能となる。 Further, since the surface of the terminal board 2 facing the circuit board when the multipolar connector is arranged on the circuit board is covered with the resin spring portion 3, the camera module 5 is inserted and each terminal board 2 is inserted. Each terminal board 2 is not in contact with the circuit board even when it is bent toward the external circuit board, and the terminal is added without increasing design restrictions such as adding other members for preventing contact. It is possible to easily prevent troubles such as an electrical short circuit between the board 2 and the circuit board.

さらに、樹脂バネ部３を端子板２のハウジング１に保持された部分と反対方向に延設してハウジング１の梁状部１ｄと一体に繋がるようにすることで、各端子板２の可撓部と樹脂バネ部３が撓んだときにより大きな復元力が発生し、より確実に当接部２ｂと端子部５ａとが電気的に接続されるようにすることが可能となるとともに、各端子板２が異常変形して塑性変形してしまうなどの不具合を防止することが可能となる。 Further, the resin spring portion 3 is extended in the direction opposite to the portion of the terminal plate 2 held by the housing 1 so as to be integrally connected to the beam-shaped portion 1d of the housing 1, so that the flexibility of each terminal plate 2 is achieved. When the portion and the resin spring portion 3 are bent, a greater restoring force is generated, and the contact portion 2b and the terminal portion 5a can be more reliably electrically connected to each other. It is possible to prevent problems such as abnormal deformation of the plate 2 and plastic deformation.

ここで、各樹脂バネ部３の厚みは樹脂の素材や形状等に応じて適宜設定されればよく、一定の厚みでなくてもよい。また、ハウジング１、端子板２及び樹脂バネ部３をインサート成形により一体成形しない場合において、ハウジング１を形成した後、樹脂バネ部３が別工程で既に被着された端子板２を組み付けるようにした構成としてもよく、このときにも、端子板２だけが撓む場合に比べて大きな復元力を得ることが可能となり、当接部２ｂと端子部５ａとを確実に電気的に接続させることが可能となる。 Here, the thickness of each resin spring part 3 should just be set suitably according to the raw material, shape, etc. of resin, and does not need to be constant thickness. Further, in the case where the housing 1, the terminal plate 2 and the resin spring portion 3 are not integrally formed by insert molding, after the housing 1 is formed, the terminal plate 2 to which the resin spring portion 3 is already attached in a separate process is assembled. Even at this time, it is possible to obtain a greater restoring force than when only the terminal plate 2 bends, and the contact portion 2b and the terminal portion 5a are reliably electrically connected. Is possible.

なお、本発明は上記実施形態の構成に限定するものではなく、発明の範囲を変更しない範囲で適宜に種々の変形が可能である。例えば、端子板２の数は２０個に限らず、回路基板と接続させる外部機器に対応して適宜設定してあればよい。また、外部機器はカメラモジュール５に限らず、例えば無線通信用等、種々の機器を用いることが可能であり、回路基板に対して上方から挿入するものに限らず、回路基板の面に沿った方向に挿入するような、例えばカード形状等の外部機器であってもよい。 In addition, this invention is not limited to the structure of the said embodiment, A various deformation | transformation is suitably possible in the range which does not change the scope of the invention. For example, the number of terminal boards 2 is not limited to 20, and may be set as appropriate in accordance with the external device to be connected to the circuit board.
