Abstract
Description
この発明は、レンズの交換が可能なデジタルカメラのレンズの取付部に用いられているコネクタに関するものである。The present invention relates to a connector used in a lens mounting portion of a digital camera capable of exchanging lenses.
従来、主流として用いられているものは図１のように一般的に用いられているプローブピンと同じものでプランジャー（１）とバーレル（２）及びコイルスプリングでできた加圧スプリング（３）より主に構成されており、プランジャー（１）の先端は概略球面形状でカメラレンズのブロックに組み込まれた端子部とは加圧スプリング（３）のバネ力により機械的に接触し、バーレル（２）の中程はプローブピンを固定するプラスチック製の固定モールド（５）に圧入固定され、下側のリード部は底面に取り付けられたフレキシブルプリントサーキットボード（通称ＦＰＣ）の貫通穴を通してＦＰＣパッド（１０）とはんだ付けにて接続されて用いられていた。 Conventionally, the mainstream one is the same as a commonly used probe pin as shown in FIG. 1, and is composed of a plunger (1), a barrel (2) and a pressure spring (3) made of a coil spring. The distal end of the plunger (1) has a substantially spherical shape and mechanically contacts with the terminal portion incorporated in the camera lens block by the spring force of the pressure spring (3). ) Is press-fitted and fixed in a plastic fixing mold (5) for fixing the probe pin, and the lower lead portion is passed through a through hole of a flexible printed circuit board (commonly called FPC) attached to the bottom surface. ) And soldered to be used.
そのためには次のような問題が有った。
（イ）プローブピンはこれを固定するためのバーレルをモールドブロックに圧入固定する必要があるがバーレルの一端をＦＰＣにはんだつけする際にバーレルの全体が加熱され、モールドブロックの圧入部が熱膨張したり溶けたりするために圧入が緩くなり、接着剤等を用いて補強する必要があった。
（ロ）０．２ミリ程度の厚さのＦＰＣへの半田付け作業が必要であるため作業性や信頼性に問題が在った。
（ハ）プローブピンの部品点数は最低３点でありしかも加工が難しいため単品としても高価であった。For that purpose, there were the following problems.
(B) The probe pin needs to be press-fitted and fixed to the mold block with a barrel for fixing it, but when the one end of the barrel is soldered to the FPC, the whole barrel is heated, and the press-fit portion of the mold block is thermally expanded. Therefore, the press-fit becomes loose because it melts or melts, and it is necessary to reinforce it with an adhesive or the like.
(B) There is a problem in workability and reliability because the soldering work to the FPC having a thickness of about 0.2 mm is necessary.
(C) The number of parts of the probe pin is at least three points, and since it is difficult to process, it was expensive as a single product.
プランジャーは従来のものと類似の形状とし、コイルスプリングは電気導体および加圧部材としての２機能をもたせ、一端をプランジャーの底面、他端をＦＰＣに設けたパッドにバネ力による加圧接触とし、ＦＰＣの裏面にはコイルスプリングから生じる加圧力を支えるために支持板を設けた。The plunger has a shape similar to that of the conventional one, the coil spring has two functions as an electric conductor and a pressure member, one end is the bottom surface of the plunger and the other end is a pressure contact by spring force to the pad provided on the FPC A support plate was provided on the back surface of the FPC to support the pressure applied from the coil spring.
極数分のプランジャー、コイルスプリング及び一枚の支持板から主に構成され、これらは形状が単純なため製造が容易であり、複雑な組立を必要としないため従来品に較べ安価である。It is mainly composed of plungers, coil springs and a single support plate for the number of poles, and these are simple in shape and easy to manufacture, and do not require complicated assembly, so they are less expensive than conventional products.
ＦＰＣとの接続はコイルスプリング及び支持板による機械的な一括・加圧接触としたため作業性が良好で安価でありしかも半田付けのような不確かさやモールドに対する損傷がないため信頼性が高い。The connection with the FPC is a mechanical batch / press contact with a coil spring and a support plate, so that the workability is good and inexpensive, and the reliability is high because there is no uncertainty such as soldering or damage to the mold.
相手との接触時のプランジャーの上下動作の際には横からの力が作用しながら下方に押し込まれるが、金属製のプランジャーとプラスチックスでできた固定モールドに設けられたガイド部との摩擦であるため従来の金属同士の摩擦に較べ摩耗が少なくスムーズな動作が可能である。When the plunger moves up and down during contact with the other party, it is pushed downward while acting from the side, but the metal plunger and the guide part provided on the fixed mold made of plastics Since it is a friction, it can be operated smoothly with less wear compared to the friction between conventional metals.
以下に本発明の実施の形態を、図２、図３を用いて説明する。
（イ）金属製の概略段付き円柱形状で接点・ガイド部（１３）及び接点・抜け止め部（１２）からなるプランジャー（１）をプラスチックスでできた固定モールド（５）に設けた概略円柱状のガイド部（６）及びガイド部（６）より径の大きな支持穴（９）に上下動作の可能な状態で設ける。
（ロ）圧縮形で電気導体でできたスプリング、加圧スプリング（３）を接点・抜け止め部（１２）とＦＰＣ（４）に設けられたＦＰＣパッド（１０）の間に位置ズレなく設ける。
（ハ）ＦＰＣ（４）の底面に剛性の高い素材でできた支持板（１１）を固定モールド（５）にネジ等で固定しもうける。
本案は以上の構造で、使用の際は、必要とする極数分のプランジャー（１）、加圧スプリング（３）、及び極数分の配線がされた１枚のＦＰＣ（４）、及び１枚の支持板（１１）を固定モールド（５）に組み込みネジ等で固定された状態で、レンズ側ブロック（１４）と組合わされ使用される。レンズ側ブロック（１４）に組み込まれたレンズブロック側接点（１５）とは回転動作及び斜面を介してプランジャーが下側に押し込まれ接触する形態となる。この際接点・ガイド部（１３）の先端の形状は球面状のほかに摩擦力や摩耗を減らすために中央に平面のある台形状でも構わない。Hereinafter, embodiments of the present invention will be described with reference to FIGS.
(A) Outline of a metal-made stepped cylindrical shape having a plunger (1) comprising a contact / guide part (13) and a contact / clamping part (12) in a fixed mold (5) made of plastics. The cylindrical guide part (6) and the support hole (9) having a diameter larger than that of the guide part (6) are provided in a state in which the vertical movement is possible.
(B) A compressed spring made of an electric conductor and a pressure spring (3) are provided without misalignment between the contact / retaining part (12) and the FPC pad (10) provided on the FPC (4).
(C) A support plate (11) made of a highly rigid material is fixed to the bottom surface of the FPC (4) on the fixing mold (5) with screws or the like.
This plan has the above structure, and in use, the plunger (1) for the required number of poles, the pressure spring (3), and one FPC (4) wired for the number of poles, and One support plate (11) is used in combination with the lens side block (14) in a state where the support plate (11) is fixed to the fixing mold (5) with a built-in screw or the like. The lens block side contact (15) incorporated in the lens side block (14) is brought into contact with the plunger by being pushed downward through a rotating operation and an inclined surface. At this time, the shape of the tip of the contact / guide portion (13) may be a trapezoidal shape having a flat surface in the center in order to reduce frictional force and wear in addition to the spherical shape.
