Description

本発明は、携帯電話やノートパソコンやデジタルカメラ等に使用されるコネクタに関するもので、特にフレキシブルプリント基板(以下「FPC」という)やフレキシブルフラットケーブル(以下「FFC」という)にコンタクトを押しける機構に関するものである。 The present invention relates to connectors that are used in cellular phones and laptop computers and digital cameras, etc., Keru One press contact particularly on a flexible printed board (hereinafter referred to as "FPC") or flexible flat cable (hereinafter referred to as "FFC") It relates to the mechanism.

携帯電話やCCDカメラ等に使用されるコネクタは、狭ピッチで極薄(所謂軽薄短小)であり、主にハウジングとコンタクトとスライダーとから構成され、ハウジングとスライダーとでFPC又はFFCを挟持する構造である。ハウジングとスライダーとでFPC又はFFCを保持する方法には、色々考えられるが、中でもハウジングにFPC又はFFCを挿入した後にスライダーを挿入しFPC又はFFCをコンタクトに押しつける構造のものが多い。   A connector used for a mobile phone, a CCD camera, etc. is a narrow pitch and extremely thin (so-called light thin short), and is mainly composed of a housing, a contact, and a slider, and the FPC or FFC is sandwiched between the housing and the slider. It is. There are various methods for holding the FPC or FFC between the housing and the slider. However, there are many methods in which the slider is inserted after the FPC or FFC is inserted into the housing and the FPC or FFC is pressed against the contact.

ハウジングには、コンタクトが挿入される所要数の挿入孔が設けられるとともにFPC又はFFCが挿入される嵌合口が設けられている。   The housing is provided with a required number of insertion holes into which contacts are inserted and a fitting port into which an FPC or FFC is inserted.

コンタクト64は図6のように略コ字形状をしており、主にFPC40又はFFCと接触する接触部22と基板等に接続する接続部24とハウジング62に固定される固定部42とから構成されている。このコンタクト64は、圧入等によってハウジング62に固定されている。 The contact 64 has a substantially U-shape as shown in FIG. 6 , and is mainly composed of a contact portion 22 that comes into contact with the FPC 40 or FFC, a connection portion 24 that is connected to a substrate or the like, and a fixed portion 42 that is fixed to the housing 62. Has been. The contact 64 is fixed to the housing 62 by press fitting or the like.

例えば、スライダー66は、図6のように略楔形状をしており、所要数のコンタクト64が配置されたハウジング62に、FPC40又はFFCを挿入した後に、前記スライダー66を挿入する。このようなスライダー66は、主にハウジング62に装着される装着部74とFPC40又はFFCをコンタクト64の接触部22に押圧する押圧部68とを備えている。FPC40又はFFCが挿入される以前は、スライダー66はハウジング62に仮装着された状態になっており、FPC40又はFFCが挿入された後にスライダー66を挿入すると、図6(B)のようにFPC40又はFFCと平行に前記スライダー66の押圧部68が挿入され、コンタクト64の接触部22にFPC40又はFFCが押圧されるようになる。 For example, the slider 66 has a substantially wedge shape as shown in FIG. 6 , and after inserting the FPC 40 or FFC into the housing 62 in which the required number of contacts 64 are arranged, the slider 66 is inserted. The slider 66 includes a mounting portion 74 that is mainly mounted on the housing 62 and a pressing portion 68 that presses the FPC 40 or FFC against the contact portion 22 of the contact 64. Before the FPC 40 or FFC is inserted, the slider 66 is temporarily attached to the housing 62. When the slider 66 is inserted after the FPC 40 or FFC is inserted, the FPC 40 or the FFC is inserted as shown in FIG. The pressing portion 68 of the slider 66 is inserted in parallel with the FFC, and the FPC 40 or FFC is pressed against the contact portion 22 of the contact 64.

近年、この種のコネクタ60には、より低背位化の要求が強くなってきているが、上述した構造のコネクタ60では、図6(B)のように6層(ハウジング62の厚み方向両側の壁・コンタクト64の接触部22と受け部70の厚さ・スライダー66の押圧部68の厚さ・FPC40又はFFCの厚さ)構造になっている。低背位化を考えると、コンタクト64の受け部70を省略し、5層(ハウジング62の厚み方向両側の壁・コンタクト64の接触部22の厚さ・スライダー66の押圧部68の厚さ・FPC40又はFFCの厚さ)構造にすることはできるが、各部位の強度や仕様等からこれ以上低背位化が出来ないといった解決すべき課題があった。   In recent years, this type of connector 60 has been increasingly required to have a lower profile, but the connector 60 having the above-described structure has six layers (both sides in the thickness direction of the housing 62) as shown in FIG. The thickness of the contact portion 22 of the contact 64 and the receiving portion 70, the thickness of the pressing portion 68 of the slider 66, and the thickness of the FPC 40 or FFC). Considering the low profile, the receiving part 70 of the contact 64 is omitted, and five layers (the walls on both sides in the thickness direction of the housing 62, the thickness of the contact part 22 of the contact 64, the thickness of the pressing part 68 of the slider 66, The thickness of the FPC 40 or the FFC) can be made, but there is a problem to be solved such that the height cannot be lowered any more due to the strength and specifications of each part.

また、上述のような構造のコネクタ60では、ハウジング62の嵌合口18側のみで、FPC40又はFFCの挿入とコンタクト64の接触部22をFPC40又はFFCに押しつける動作を行っているので、コネクタが小型化すればするほど作業性が悪いと言った問題点もある。   Further, in the connector 60 having the structure as described above, the FPC 40 or FFC is inserted and the contact portion 22 of the contact 64 is pressed against the FPC 40 or FFC only on the fitting port 18 side of the housing 62, so the connector is small. There is also the problem that workability becomes worse the more it becomes.

さらにまた、コネクタ60のピッチの狭小化が要求された場合、従来の構造のようにコンタクト64を一方向から挿入したのでは、コネクタの狭小化にも限界があった。   Furthermore, when it is required to narrow the pitch of the connector 60, if the contacts 64 are inserted from one direction as in the conventional structure, there is a limit to narrowing the connector.

本発明は、このような従来の問題点に鑑みてなされたもので、各部位の強度や仕様等を損なうことなく、スライダー16でFPC40又はFFCを確実にコンタクト14の接触部22に押圧することができ、作業性がよく、ピッチの狭小化や低背位化が可能なコネクタを提供せんとするものである。   The present invention has been made in view of such conventional problems, and the FPC 40 or the FFC is reliably pressed against the contact portion 22 of the contact 14 by the slider 16 without impairing the strength and specifications of each part. Therefore, it is intended to provide a connector that can be manufactured, has good workability, and can reduce the pitch and reduce the height.
