Description

【0001】
【発明の属する技術分野】
本発明は、コネクタにおけるコンタクトとインシュレータの形状及び構造に関し、一用途例として狭ピッチFPC(Flexible Printed Circuit)用コネクタに関する。
【0002】
【従来の技術】
従来のFPC用コネクタでは、コンタクトのピッチ方向において、各コンタクトと各コンタクトを保持するインシュレータとの間にクリアランスが設けられ、各コンタクトとインシュレータが雰囲気にさらされている。したがって、各コンタクトとインシュレータとの間にフラックスの毛細管現象の発生が防止される。しかし、コンタクトのピッチが狭小化するにしたがって、ピッチ方向にクリアランスを設けることは、物理的に困難に至っている。
【0003】
この種のFPC用コネクタは、多数提案されている(例えば、特許文献1参照。)。
【0004】
【特許文献1】
特開2001−57260号公報(第3,4頁、図1−3)
【0005】
【発明が解決しようとする課題】
そこで、本発明は、従来のFPC用コネクタの欠点を改良し、コンタクトのピッチを拡大せずに、各コンタクトとインシュレータとの間にも毛細管現象に基因するフラックスの上がりが発生することを抑制できるコネクタを提供しようとするものである。
【0006】
【課題を解決するための手段】
本発明は、前記課題を解決するため、次の手段を採用する。
【0007】
一定のピッチで並設される複数のコンタクトと、前記各コンタクトを保持するインシュレータとから構成されるコネクタにおいて、前記各コンタクトは、前記インシュレータに保持される保持部と、接続対象物と接触する接触部と、端子部と、前記接触部と前記端子部とを連結する連結部とを有し、前記インシュレータは、少なくとも前記保持部を収容する第1の収容部と、前記端子部と前記連結部のそれぞれの少なくとも一部を収容する第2の収容部とを有し、前記ピッチ方向において、前記第2の収容部は前記第1の収容部よりも幅広に形成され、前記第2の収容部に収容された前記連結部は、傾斜したクランク状に形成され、前記接触部の中心線と前記端子部の中心線とは異なるコネクタ。
【0008】
【発明の実施の形態】
本発明の一実施の形態例のコネクタについて図1〜図6を参照して説明する。
【0009】
コネクタ1は、インシュレータ2と、インシュレータ2に一定のピッチで保持される多数のコンタクト3と、各コンタクト3に対向するようにインシュレータ2にそれぞれ保持される多数の弾性変形可能なコンタクト4(図6参照)と、各対向コンタクト4を操作するアクチュエータ5とから構成される。
【0010】
コネクタ1は、FPC等の相手側コネクタ11と接続する。
【0011】
コネクタ1におけるコンタクト3とインシュレータ2の要部の正面図を図1に、側面図を図2に、下面図を図3に、それぞれ示す。
【0012】
図4は、コンタクト3の三面図、図5は、コンタクト3の斜視図を、それぞれ示す。
【0013】
各コンタクト3は、圧入部3aと、圧入部3aに連続する接触部3bと、接触部3bに連続して傾斜したクランク状に形成された連結部3cと、連結部3cに連続する端子部3dとから一体に構成される。接触部3bの上面側に、接点3b1が突出して形成される。
【0014】
圧入部3aは、インシュレータ2に設けられた第1の収容部2aに圧入される。接点3b1は、相手側コネクタ11の裏面に形成された信号パターン(図示せず)と接触する。連結部3cは、インシュレータ2に設けられた第2の収容部2bに収容される。端子部3dは、プリント基板(図示せず)の表面に形成された信号パターンと接続する。
【0015】
図1において、接触部3bの中心線と端子部3dの中心線との間の距離をEとし、端子部3dの左側面と第2の収容部2bの左壁面との間のクリアランスをaとし、端子部3dの右側面と第2の収容部2bの右壁面との間のクリアランスをbとする。
【0016】
図3において、コンタクト3における接点3b1から連結部3cの端子部(SMT部)3d側までのピッチ方向に直交する方向における距離をDとし、連結部3cの左側面と第2の収容部2bの左壁面との間の最大のクリアランスをcとし、連結部3cの右側面と第2の収容部2bの右壁面との間の最大のクリアランスをdとする。
【0017】
このように、コンタクト3とインシュレータ2が構成されているため、クリアランスcはクリアランスaよりも大きく、また、クリアランスdはクリアランスbよりも大きいから、雰囲気にさらされるコンタクト3とインシュレータ2の各面積が増大するので、毛細管現象に基因するフラックスの上がりが抑制される。更に、コンタクト3の連結部3cは、傾斜したクランク状に形成されているから、接点3b1から連結部3cの端子部3d側までの実際の距離は、上述した距離Dよりも大きいので、毛細管現象に基因するフラックスの上がりが抑制される。
【0018】
コネクタ1と相手側コネクタ11との接続について図6を参照して説明する。
【0019】
インシュレータ2に保持された多数のコンタクト3にそれぞれ対向するように、多数の弾性変形可能なコンタクト4がインシュレータ2に保持される。コンタクト4における可動接点4aと被押動部4bと端子部4cが、図示されている。
【0020】
相手側コネクタ11がコネクタ1のインシュレータ2に設けられた嵌合口2cに挿入された後に、アクチュエータ5をその押圧部5aを中心として90°矢印方向に回転させる。すると、押圧部5aは、カムの役割を果たしてコンタクト4の被押動部4bを押し上げるから、可動接点4aは、相手側コネクタ11の表面を押圧してこの表面に形成された信号パターン(図示せず)に接触する。この結果、相手側コネクタ11の表面の信号パターンは、コンタクト4の可動接点4a、中間部(図示せず)及び端子部4cを介してプリント基板(図示せず)の表面に形成された信号パターンと接続する。また、相手側コネクタ11の裏面に形成された信号パターン(図示せず)は、コンタクト3の接点3b1に接触する。この結果、相手側コネクタ11の裏面の信号パターンは、コンタクト3を介してプリント基板の表面に形成された信号パターンと接続する。
【0021】
【発明の効果】
以上の説明から明らかなように、本発明によれば、次の効果が奏される。
【0022】
1.コンタクトの接点部と端子部との間に傾斜したクランク状に形成された連結部を設けることによって、コンタクトとインシュレータとの間に大きいクリアランスが確保される。したがって、コンタクトのピッチを拡大せずに、雰囲気にさらされるコンタクトとインシュレータの各面積が増大するので、フラックスの上がりが抑制される。
【0023】
2.コンタクトにおける接点から連結部の端子部(SMT部)側までの距離が長くなるので、更にフラックスの上がりが抑制される。

BACKGROUND OF THE INVENTION
The present invention relates to the shape and structure of contacts and insulators in a connector, and relates to a connector for a narrow pitch FPC (Flexible Printed Circuit) as one application example.
[0002]
[Prior art]
In the conventional FPC connector, in the contact pitch direction, a clearance is provided between each contact and the insulator that holds each contact, and each contact and the insulator are exposed to the atmosphere. Therefore, the occurrence of capillary action of the flux between each contact and the insulator is prevented. However, as the contact pitch becomes narrower, it is physically difficult to provide clearance in the pitch direction.
[0003]
Many such FPC connectors have been proposed (see, for example, Patent Document 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 2001-57260 (pages 3, 4 and 1-3)
[0005]
[Problems to be solved by the invention]
Therefore, the present invention improves the drawbacks of the conventional FPC connector, and can suppress the increase in flux due to capillary action between each contact and the insulator without increasing the contact pitch. It is intended to provide a connector.
[0006]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems.
[0007]
In the connector comprising a plurality of contacts arranged in parallel at a constant pitch and an insulator for holding each contact, each contact is in contact with a holding portion held by the insulator and a connection object. And a terminal portion, and a connecting portion that connects the contact portion and the terminal portion, wherein the insulator includes at least a first accommodating portion that accommodates the holding portion, the terminal portion, and the connecting portion. A second accommodating portion that accommodates at least a part of each of the first accommodating portion, and the second accommodating portion is formed wider than the first accommodating portion in the pitch direction. The connecting portion housed in the connector is formed in an inclined crank shape, and a center line of the contact portion is different from a center line of the terminal portion.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
A connector according to an embodiment of the present invention will be described with reference to FIGS.
[0009]
The connector 1 includes an insulator 2, a number of contacts 3 held by the insulator 2 at a constant pitch, and a number of elastically deformable contacts 4 held by the insulator 2 so as to face the contacts 3 (FIG. 6). And an actuator 5 for operating each of the opposing contacts 4.
[0010]
The connector 1 is connected to a counterpart connector 11 such as an FPC.
[0011]
The front view of the principal part of the contact 3 and the insulator 2 in the connector 1 is shown in FIG. 1, the side view is shown in FIG. 2, and the bottom view is shown in FIG.
[0012]
FIG. 4 is a three-view diagram of the contact 3, and FIG. 5 is a perspective view of the contact 3.
[0013]
Each contact 3 includes a press-fit portion 3a, a contact portion 3b continuous to the press-fit portion 3a, a connecting portion 3c formed in a crank shape continuously inclined to the contact portion 3b, and a terminal portion 3d continuous to the connecting portion 3c. It is composed integrally with. On the upper surface side of the contact portion 3b, a contact 3b1 is formed so as to protrude.
[0014]
The press-fitting part 3 a is press-fitted into the first accommodating part 2 a provided in the insulator 2. The contact 3b1 contacts a signal pattern (not shown) formed on the back surface of the mating connector 11. The connecting portion 3 c is accommodated in the second accommodating portion 2 b provided in the insulator 2. The terminal portion 3d is connected to a signal pattern formed on the surface of a printed board (not shown).
[0015]
In FIG. 1, the distance between the center line of the contact portion 3b and the center line of the terminal portion 3d is E, and the clearance between the left side surface of the terminal portion 3d and the left wall surface of the second housing portion 2b is a. The clearance between the right side surface of the terminal portion 3d and the right wall surface of the second housing portion 2b is b.
[0016]
In FIG. 3, the distance in the direction orthogonal to the pitch direction from the contact 3b1 in the contact 3 to the terminal part (SMT part) 3d side of the connecting part 3c is D, and the left side surface of the connecting part 3c and the second accommodating part 2b Let c be the maximum clearance between the left wall surface and d be the maximum clearance between the right side surface of the connecting portion 3c and the right wall surface of the second housing portion 2b.
[0017]
Since the contact 3 and the insulator 2 are thus configured, the clearance c is larger than the clearance a, and the clearance d is larger than the clearance b. Therefore, the areas of the contact 3 and the insulator 2 exposed to the atmosphere are Since it increases, the rise of the flux resulting from capillary action is suppressed. Further, since the connecting portion 3c of the contact 3 is formed in an inclined crank shape, the actual distance from the contact 3b1 to the terminal portion 3d side of the connecting portion 3c is larger than the distance D described above, so that the capillary phenomenon The rise in flux due to the is suppressed.
[0018]
Connection between the connector 1 and the mating connector 11 will be described with reference to FIG.
[0019]
A number of elastically deformable contacts 4 are held by the insulator 2 so as to face the number of contacts 3 held by the insulator 2. A movable contact 4a, a driven portion 4b, and a terminal portion 4c in the contact 4 are illustrated.
[0020]
After the mating connector 11 is inserted into the fitting port 2c provided in the insulator 2 of the connector 1, the actuator 5 is rotated in the direction of the arrow by 90 ° about the pressing portion 5a. Then, since the pressing part 5a plays the role of a cam and pushes up the driven part 4b of the contact 4, the movable contact 4a presses the surface of the mating connector 11 to form a signal pattern (not shown). Contact). As a result, the signal pattern on the surface of the mating connector 11 is a signal pattern formed on the surface of the printed circuit board (not shown) via the movable contact 4a of the contact 4, the intermediate part (not shown) and the terminal part 4c. Connect with. In addition, a signal pattern (not shown) formed on the back surface of the mating connector 11 contacts the contact 3 b 1 of the contact 3. As a result, the signal pattern on the back surface of the mating connector 11 is connected to the signal pattern formed on the surface of the printed board via the contact 3.
[0021]
【The invention's effect】
As will be apparent from the above description, the present invention provides the following effects.
[0022]
1. A large clearance is ensured between the contact and the insulator by providing a connecting portion formed in an inclined crank shape between the contact portion and the terminal portion of the contact. Therefore, since the areas of the contact and the insulator that are exposed to the atmosphere increase without increasing the contact pitch, an increase in flux is suppressed.
[0023]
2. Since the distance from the contact point in the contact to the terminal part (SMT part) side of the connecting part becomes longer, the flux rise is further suppressed.
