Description

本発明は、プリント配線基板に装着して電線とプリント配線基板とを電気接続するコネクタに関する。   The present invention relates to a connector that is mounted on a printed wiring board and electrically connects an electric wire and the printed wiring board.

従来、プリント配線基板の回路と電線との接続は、図８に示すように配線引き出し用のプラグ１１０を基板回路面１４０ａ上に設け、電線１０３に圧着コネクタソケット１１１を取り付けて、圧着コネクタソケット１１１とプラグ１１０とを嵌合するものであった。
しかし、この方法ではソケット、プラグ等の部品点数及びその組立工数が多い上に、プラグ１１０の基板１４０への半田付け工程が必要なためコスト高となっていた。
また、回路面１４０ａ上に電線１０３を引き回すための空間が必要であるために取付スペースの薄型化が困難であった。
特開２０００−９１００２号公報には、部品点数を少なくしたコネクタを開示するが基板への半田付が必要な点では上記従来技術と同様に多くの工数を要するものである。 Conventionally, as shown in FIG. 8, the circuit of the printed wiring board is connected to the electric wire by providing a wiring drawing plug 110 on the circuit board surface 140 a and attaching the crimp connector socket 111 to the electric wire 103. And the plug 110 are fitted.
However, in this method, the number of parts such as sockets and plugs and the number of assembly steps are large, and the process of soldering the plug 110 to the substrate 140 is necessary, resulting in high cost.
In addition, since a space for routing the electric wire 103 is necessary on the circuit surface 140a, it is difficult to reduce the mounting space.
Japanese Patent Application Laid-Open No. 2000-91002 discloses a connector with a reduced number of parts, but requires a lot of man-hours as in the prior art in that soldering to a substrate is required.

特開２０００−９１００２号公報Japanese Patent Laid-Open No. 2000-91002

本発明は上記技術的課題に鑑みて、電気接続の信頼性が高く、部品点数が少なく組立性に優れ、小型化・薄型化を図るのに効果的なコネクタの提供を目的とする。   In view of the above technical problems, an object of the present invention is to provide a connector that is highly reliable in electrical connection, has a small number of parts, is excellent in assemblability, and is effective for downsizing and thinning.

請求項１記載のコネクタは、電線と基板回路とを接続するコネクタであって、ハウジングとターミナルとを備え、ターミナルは、一方の基板側に弾性接触片を有し、他方に電線を接続してあり、ハウジングは、基板装着面と、当該基板装着面におおむね平行にターミナルを配置するターミナル収納部とを有し、ターミナル収納部は、ターミナル挿入口と、基板装着面側に弾性接触片に設けた接点部の突出口とを有し、ターミナルをハウジングのターミナル挿入口に挿入して突出口から接点部を突出させていることを特徴とする。   The connector according to claim 1 is a connector for connecting an electric wire and a board circuit, comprising a housing and a terminal, the terminal having an elastic contact piece on one board side and connecting the electric wire on the other side. And the housing has a board mounting surface and a terminal housing portion for arranging the terminal substantially parallel to the board mounting surface. The terminal housing portion is provided on the terminal insertion port and the elastic contact piece on the board mounting surface side. And a protruding portion of the contact portion, and a terminal is inserted into the terminal insertion port of the housing so that the contact portion protrudes from the protruding port.

ここで、基板装着面におおむね平行にターミナルを配置するターミナル収納部とは、ターミナルを基板装着面に対して平行となる方向にハウジング側のターミナル収納部に挿入できることをいう。   Here, the terminal housing portion in which the terminal is disposed substantially parallel to the board mounting surface means that the terminal can be inserted into the terminal housing portion on the housing side in a direction parallel to the board mounting surface.

請求項２記載のコネクタは、ターミナルは、ガイド片を有し、ターミナル収納部は、ガイド溝を有し、ターミナルのガイド片をガイド溝に沿って挿入してあることを特徴とする。   The connector according to claim 2 is characterized in that the terminal has a guide piece, the terminal accommodating portion has a guide groove, and the guide piece of the terminal is inserted along the guide groove.

ここでターミナルに設けたガイド片とは、ハウジング側に形成したガイド溝に沿って挿入するためのものである。
従って、ターミナルの挿入方向に沿った両側の端部にそれぞれガイド片を形成し、これに対応して、ハウジング側にも収納部の両側にガイド溝を形成すると弾性接触片が基板に圧接した際の反力を両側のガイド溝で安定して受けることができてよい。 Here, the guide piece provided in the terminal is for insertion along a guide groove formed on the housing side.
Therefore, when guide pieces are formed at both ends along the insertion direction of the terminal, and correspondingly, guide grooves are formed on both sides of the housing portion on the housing side, the elastic contact pieces are pressed against the substrate. It may be possible to stably receive the reaction force in the guide grooves on both sides.

請求項３に記載のコネクタにおいては、ターミナルと、ターミナル収納部とは、一方に設けたランスと他方に設けたランス係止部とで係合していることを特徴とする。
これによりターミナルをターミナル収納部に挿入するだけでハウジングに係止できる。 The connector according to claim 3 is characterized in that the terminal and the terminal storage portion are engaged by a lance provided on one side and a lance locking portion provided on the other side.
As a result, the terminal can be locked to the housing simply by being inserted into the terminal housing.

請求項４に記載のコネクタにおいては、弾性接触片は複数に分岐して複数の接点部を設けてあることを特徴とする。
ここで、弾性接触片を複数に分岐させるのは基板側の接触端子部に複数の接点で接続する趣旨であり、接点圧を考慮しつつ、ターミナルのプレス加工時等に分断する。 The connector according to claim 4 is characterized in that the elastic contact piece is branched into a plurality of portions and a plurality of contact portions are provided.
Here, the purpose of branching the elastic contact piece into a plurality is to connect to the contact terminal portion on the substrate side with a plurality of contacts, and it is divided at the time of press processing of the terminal while taking into account the contact pressure.

請求項５記載のコネクタにおいては、ハウジングは、基板側にコネクタ取付凹部を形成して基板装着面としてあることを特徴とする。
ハウジングの基板側にコネクタ取付凹部を形成するのは凹部を形成したことによりその段差寸法分だけコネクタの基板への接続高さを低くする趣旨である。 The connector according to claim 5 is characterized in that the housing has a connector mounting recess formed on the substrate side to serve as a substrate mounting surface.
The purpose of forming the connector mounting recess on the board side of the housing is to reduce the height of connection of the connector to the board by the height of the step.

請求項６記載のコネクタにおいては、ハウジングは、基板との係止部を有していることを特徴とする。
ハウジングの基板装着面が基板側の接触端子部を覆うように接続できればコネクタと基板との接続方法は特に限定されないが請求項６記載の発明のようにハウジングに基板との係止部を設けるとコネクタを基板に係止させるだけで接続できる。 The connector according to claim 6 is characterized in that the housing has a locking portion with the substrate.
The connection method between the connector and the substrate is not particularly limited as long as the substrate mounting surface of the housing can be connected so as to cover the contact terminal portion on the substrate side. However, when the housing is provided with a locking portion with the substrate as in the invention of claim 6. Connection is possible simply by locking the connector to the board.

本発明に係るコネクタにおいては、基板装着面に対しておおむね平行に、ターミナルをターミナル挿入口からターミナル収納部に挿入できるためにターミナルを基板回路面とほぼ平行に収納し、基板側に向けて突出した弾性接触片の接点部は、撓むように接触端子部と接続するため、コネクタの基板回路面からの高さを低く出来る。
ここで、ハウジングの基板側にコネクタ取付凹部を形成した場合には更に凹部段差分だけ低く出来る。
また、電線を基板回路面と平行となるようにターミナルに接続することになるので、非常に薄くコンパクトな構造で電線を基板に接続出来る。
このコネクタは、シンプルな構造で部品点数が少ないことから極めて小型化・薄型化出来る。 In the connector according to the present invention, since the terminal can be inserted into the terminal accommodating portion from the terminal insertion port substantially parallel to the board mounting surface, the terminal is accommodated substantially parallel to the circuit surface of the board and protrudes toward the board side. Since the contact portion of the elastic contact piece is connected to the contact terminal portion so as to bend, the height of the connector from the circuit board surface can be reduced.
Here, when the connector mounting concave portion is formed on the substrate side of the housing, it can be further lowered by the concave step.
In addition, since the electric wire is connected to the terminal so as to be parallel to the circuit surface of the substrate, the electric wire can be connected to the substrate with a very thin and compact structure.
Since this connector has a simple structure and a small number of parts, it can be made extremely small and thin.

コネクタの組み立ては、ターミナルに電線を接続して、ターミナルのガイド片を挿入口からガイド溝に沿って挿入し、ランスをスナップ係止させることで出来るため、非常に簡単であり、組立工数が少なくコスト低減効果が大きい。   The assembly of the connector is very simple and requires fewer assembly steps because it is possible to connect the wire to the terminal, insert the terminal guide piece along the guide groove from the insertion slot, and snap the lance. Great cost reduction effect.

ターミナル側の接点部の基板接触端子部への接続は、弾性接触片を複数に分岐してそれぞれに接点部を設けた複数点での接触とすると、接続信頼性が更に高くなる。   The connection reliability of the terminal-side contact portion to the board contact terminal portion is further improved if the elastic contact piece is divided into a plurality of points and contact is made at a plurality of points each provided with a contact portion.

ハウジングに基板との係止部を設けると、この係止部を用いてコネクタを基板に装着することも可能になる。   When the housing is provided with a locking portion with the board, the connector can be attached to the board using the locking portion.

A lance engaging portion 26 is provided at the upper center portion.

ターミナル３０は短冊状片からなり、ターミナル挿入方向後ろ側には電線３を圧着接続する電線固定部３６を設け、ターミナル挿入方向先側には短冊状片を基板側に向けて鈍角に曲げた弾性接触片３１を設けてある。
電線固定部３６と弾性接触片３１との間にはターミナル固定部３４を設けてあり、ターミナル固定部３４は、短冊状片の幅方向両側を幅方向に突出させたガイド片３３を有し、中央にはコ字状に切り込み３４ａを入れて、舌片部を上方へ鈍角に曲げることでランス３５としている。
ターミナル３０はガイド片３３をガイド溝２５に嵌め、ランス３５はランス係合部２６の係止面２６ａに係止して、収納部２１内に短冊状片の扁平している側面を基板回路面４０ｂ側に向けて収納してある。
弾性接触片３１はその先端側を二股に分岐させて、突出口２３側に傾斜して延ばし、先端部分に基板４０側に丸みを形成するように曲げた接点部３２を設けて、この接点部３２を突出口２３から突出させて基板４０の接触端子部４３に接触させる構造となっている。
１つのターミナル３０は、２つの接点部３２をそれぞれ、基板側に向けた傾斜を撓ませるように１つの接触端子部４３に弾性接続させる。
ターミナル３０は、２つの接点部３２のいずれかが接触端子部４３に導通すれば接続するため接続信頼性が高い。
電線固定部３６は、被覆保持部３６ａが電線３の被覆にその一部を食い込ませながら、電線３を被覆上から圧着して保持し、導体保持部３６ｂで電線３の導体を圧着して導通して、電線３を基板回路面４０ａとほぼ平行となるように接続する。
ターミナル３０のターミナル収納部２１内への収納は、まず電線固定部３６に電線３の端部を接続固定し、そして弾性接触片３１側からターミナル３０をターミナル挿入口２２に挿し込み、ガイド片３３をガイド溝２３に嵌めることで収納凹部２１内方へ案内しつつ、ランス３５をランス係合部２４の段形状で撓ませながら挿入する。
そして、ガイド溝２５の終端にガイド片３３を突き当ると、その位置においてランス３５がランス係合部２６のランス復帰空間２６ｂ位置となるためランス３５は、弾性復帰し、その先端が係止面２６ａに係止する。
これによりターミナル３０を位置決めして固定できる。
コネクタ１０の組み立ては、従来のように半田付けを必要とせず、電線固定部に電線を圧着接続して、ターミナル３０を収納部２１内にスナップ係止するだけであり、非常に生産性が高い。
またコネクタ１０は、部品点数が少なく、構造が非常にシンプルで、電線は回路面と平行に配設することから、極めて低背化することが出来る。
これにより、コネクタを取り付ける機器側の設計自由度が非常に高くなる。
コネクタ１０の高さは、例えば図２（ｂ）に示すＬＥＤモジュール基板４０のＬＥＤの側部４４ａの約２ｍｍの高さよりも低くすることが出来るため、例えば液晶パネルのバックライト用のＬＥＤモジュール基板と、電線との接続に用いると、バックライトの薄型化を効果的に図ることができる。 The terminal 30 is formed of a strip-shaped piece, and is provided with an electric wire fixing portion 36 for crimping and connecting the electric wire 3 on the rear side in the terminal insertion direction, and on the front side in the terminal insertion direction, the elastic strip is bent at an obtuse angle toward the substrate side.

One terminal 30 elastically connects two contact portions 32 to one contact terminal portion 43 so as to bend the inclination toward the substrate side.
Since the terminal 30 is connected if one of the two contact portions 32 is electrically connected to the contact terminal portion 43, the connection reliability is high.
The electric wire fixing part 36 holds the electric wire 3 by pressing it from above the covering while the covering holding part 36a bites into the covering of the electric wire 3, and presses the conductor of the electric wire 3 by the conductor holding part 36b. And the electric wire 3 is connected so that it may become substantially parallel to the board | substrate circuit surface 40a.
To store the terminal 30 in the terminal storage portion 21, first, the end portion of the electric wire 3 is connected and fixed to the electric wire fixing portion 36, and the terminal 30 is inserted into the terminal insertion port 22 from the elastic contact piece 31 side. The lance 35 is inserted while being bent in the step shape of the lance engagement portion 24 while being guided inwardly into the storage recess 21 by being fitted in the guide groove 23.
When the guide piece 33 abuts the end of the guide groove 25, the lance 35 becomes the position of the lance return space 26b of the lance engagement portion 26 at that position, so that the lance 35 is elastically restored and its tip is the locking surface. Locks to 26a.
Thereby, the terminal 30 can be positioned and fixed.
The assembly of the connector 10 does not require soldering as in the prior art, and only involves crimping and connecting the electric wire to the electric wire fixing portion and snap-locking the terminal 30 into the storage portion 21. .
Further, the connector 10 has a small number of parts, a very simple structure, and the electric wires are arranged in parallel with the circuit surface, so that the height can be extremely reduced.
This greatly increases the degree of design freedom on the device side to which the connector is attached.
Since the height of the connector 10 can be made lower than the height of about 2 mm of the LED side portion 44a of the LED module substrate 40 shown in FIG. 2B, for example, an LED module substrate for a backlight of a liquid crystal panel, for example. When used for connection to an electric wire, the backlight can be effectively reduced in thickness.

ターミナル３０ａは弾性接触片３１ａを、ターミナル収納部２１の端部分で鋭角状に折り返して、基板に向けて傾斜するように設け、弾性接触片３１ａの先端部は基板側に丸みを形成して上方へ曲げて基板との接点部３２ａとした例である。 Fig.4 (a) shows the cc sectional view taken on the line of FIG.4 (b), and shows the example which made the shape of the terminal arrange | positioned in the accommodating part of a housing into another shape.
