Description

本発明は、コンタクトを絶縁体に保持する方法として一体成型を使用する場合のコンタクトの接触部への樹脂漏れを防止するコンタクト構造に関するものである。   The present invention relates to a contact structure for preventing resin leakage to a contact portion of a contact when integral molding is used as a method for holding a contact on an insulator.

従来のコンタクト構造について説明する。従来のコンタクトは、略筒状体をしており、主に相手物と接触する接触部と絶縁体に保持される固定部とケーブルや基板に接続される接続部とを具えている。従来、コンタクトを絶縁体に保持する方法としては、一般的に圧入や引っ掛け（ランス構造）や一体成型や溶着などが考えられる。
実開平６−７３８７４号の要約によると、片側固定で、解放端側が平行に向き合う2枚の接触片４２からなる従来のソケットコンタクトの場合、相手コネクタのピンコンタクト２０が斜めに挿入されて、接触片の裏面に入り込むことがあり、するとソケットコンタクトが変形し、接触不良が発生する。この問題を解決することを目的とし、接触片４２の解放端上方に、内側に湾曲した2枚の板状の舌片４１を設け、このようにすると、ピンコンタクト２０が斜めに挿入されても、舌片４１により接触片４２の内側の方に導かれ、ソケットコンタクト４０が変形したり破損したりすることがなく、また舌片４１と接触片４２との間に隙間４３があいているので、接触片４２の変位量が十分にとれ、安定した性能が得られる構造のソケットコンタクトが開示されている。 ちなみに、実開平６−７３８７４号の実用新案登録請求の範囲によると、請求項１として、ハウジングに固定するための固定部と、相手コネクタのピンコンタクトと接触するために湾曲しバネ性を持ち一端側が固定された2枚の平行な板状接触片とを有するソケットコンタクトにおいて、前記接触片の解放端上方に、前記ピンコンタクトを前記接触片に誘導する内側に湾曲した2枚の板状の舌片を設けたことを特徴とするソケットコンタクトが開示されている。 A conventional contact structure will be described. A conventional contact has a substantially cylindrical body, and mainly includes a contact portion that comes into contact with an object, a fixed portion held by an insulator, and a connection portion connected to a cable or a substrate. Conventionally, as a method of holding a contact on an insulator, generally press-fitting, hooking (lance structure), integral molding, welding, and the like are conceivable.
According to the summary of Japanese Utility Model Laid-Open No. 6-73874, in the case of a conventional socket contact composed of two contact pieces 42 that are fixed on one side and the open end side faces in parallel, the pin contact 20 of the mating connector is inserted obliquely, In some cases, the back surface of the piece may enter, causing the socket contact to be deformed, resulting in poor contact. In order to solve this problem, two plate-like tongue pieces 41 that are curved inward are provided above the open end of the contact piece 42, so that even if the pin contact 20 is inserted obliquely, The tongue piece 41 is guided toward the inner side of the contact piece 42 so that the socket contact 40 is not deformed or damaged, and there is a gap 43 between the tongue piece 41 and the contact piece 42. A socket contact having a structure in which the displacement of the contact piece 42 can be sufficiently taken and stable performance can be obtained is disclosed. By the way, according to the claim of utility model registration of Japanese Utility Model Publication No. Hei 6-73874, as claimed in claim 1, it has a fixed portion for fixing to the housing and a curved portion to have contact with the pin contact of the mating connector. In a socket contact having two parallel plate-like contact pieces fixed on the side, two plate-like tongues curved inward to guide the pin contact to the contact piece above the open end of the contact piece A socket contact characterized by providing a strip is disclosed.

特許文献１と挙げたようなソケットコンタクトの構造のような形状が筒状をしている従来構造のものでは、前記絶縁体に前記コンタクトを保持する方法としては、一体成型は不向きであり、かつ、従来構造の前記コンタクトで一体成型を行なうとすると接触部側まで樹脂が入り込んでしまい、接続不良に繋がると言った解決すべき課題があった。
また、成型時に樹脂が接触部まで入り込まないようにするためには、金型構造が複雑で、かつ、精度が要求され、コストアップに繋がってしまう。 In the conventional structure in which the shape of the socket contact structure as described in Patent Document 1 has a cylindrical shape, as a method of holding the contact on the insulator, integral molding is not suitable, and When integral molding is performed with the contact having the conventional structure, there is a problem to be solved that the resin enters the contact portion side and leads to poor connection.
Further, in order to prevent the resin from entering the contact portion at the time of molding, the mold structure is complicated and accuracy is required, leading to an increase in cost.

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、簡単な構造で、接続不良にも繋がることがなく、かつ、コストアップにも繋がらないコンタクト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 is intended to provide a contact with a simple structure that does not lead to poor connection and does not lead to an increase in cost. .

上記目的は、相手物と接触する接触部１２と絶縁体２に保持される固定部１４とケーブルや基板に接続される接続部１６とを具えるとともに一体成型に使用される筒状のコンタクト１０において、前記接触部１２と前記接続部１４との間で下面側に、折り曲げられた防止壁２０を設けるとともに上面側に前記防止壁２０の先端が入る大きさの係止部１８を設けることで達成できる。   The object is to provide a cylindrical contact 10 used for integral molding, including a contact portion 12 that contacts an object, a fixing portion 14 that is held by the insulator 2, and a connection portion 16 that is connected to a cable or a substrate. In addition, a bent prevention wall 20 is provided on the lower surface side between the contact portion 12 and the connection portion 14, and a locking portion 18 having a size that allows the tip of the prevention wall 20 to enter is provided on the upper surface side. Can be achieved.

筒状の前記コンタクト１０が前記絶縁体２に一体成型された際に、前記防止壁２０により樹脂が前記接触部１２側に行くことを防止する。
筒状の前記コンタクト１０の防止壁２０と両側の側壁２４との隙間を０．０３〜０．０５ｍｍにするとともに前記防止壁２０と前記係止部１８との係合する大きさを０．０５〜０．１ｍｍにする。前記防止壁２０と両側の側壁２４との隙間が０．０３ｍｍ以下では前記コンタクト加工時の寸法精度が要求され、コストアップに繋がる恐れがあり、前記防止壁２０と両側の側壁２４との隙間が０．０５ｍｍ以上では樹脂の前記接触部１２側への入り込みを防止できない。前記防止壁２０と前記係止部１８との係合する大きさが０．０５ｍｍ以下では一体成型時の樹脂圧に耐えることができなく、前記防止壁２０と前記係止部１８との係合する大きさが０．１ｍｍ以上では貫通孔になる恐れもあり、貫通孔になると樹脂の入り込みを防止できなく、かつ、コンタクト１０の強度にも問題が生じる。 When the cylindrical contact 10 is integrally formed with the insulator 2, the prevention wall 20 prevents the resin from going to the contact portion 12 side.
The clearance between the prevention wall 20 of the cylindrical contact 10 and the side walls 24 on both sides is set to 0.03 to 0.05 mm, and the engagement size between the prevention wall 20 and the locking portion 18 is 0.05. -0.1 mm. If the clearance between the prevention wall 20 and the side walls 24 on both sides is 0.03 mm or less, dimensional accuracy at the time of the contact processing is required, which may lead to an increase in cost, and there is a gap between the prevention wall 20 and the side walls 24 on both sides. If it is 0.05 mm or more, the resin cannot be prevented from entering the contact portion 12 side. If the size of engagement between the prevention wall 20 and the locking portion 18 is 0.05 mm or less, the resin pressure during integral molding cannot be withstood, and the engagement between the prevention wall 20 and the locking portion 18 is not possible. If the size of the through hole is 0.1 mm or more, there is a possibility that a through hole may be formed.

本発明のコンタクト構造を使用するコネクタ１としては、複数の筒状のコンタクト１０と該コンタクト１０が保持・配列される絶縁体２とを具えるとともに前記絶縁体２が一体成型により形成されるコネクタ１において、筒状の前記コンタクト１０は相手物と接触する接触部１２と絶縁体２に保持される固定部１４とケーブルや基板に接続される接続部１６とを有し、筒状の前記コンタクト１０の前記接触部１２と前記接続部１６との間で下面側に、折り曲げられた防止壁２０を設けるとともに上面側に前記防止壁２０の先端が入る大きさの係止部１８を設け、筒状の前記コンタクト１０が前記絶縁体２に一体成型された際に、前記防止壁２０により樹脂が前記接触部１２側に行くことを防止する。
筒状の前記コンタクト１０の防止壁２０と両側の側壁２４との隙間を０．０３〜０．０５ｍｍにするとともに前記防止壁２０と前記係止部１８との係合する大きさを０．０５〜０．１ｍｍにする。前記防止壁２０と両側の側壁２４との隙間が０．０３ｍｍ以下では前記コンタクト加工時の寸法精度が要求され、コストアップに繋がる恐れがあり、前記防止壁２０と両側の側壁２４との隙間が０．０５ｍｍ以上では樹脂の前記接触部１２側への入り込みを防止できない。前記防止壁２０と前記係止部１８との係合する大きさが０．０５ｍｍ以下では一体成型時の樹脂圧に耐えることができなく、前記防止壁２０と前記係止部１８との係合する大きさが０．１ｍｍ以上では貫通孔になる恐れもあり、貫通孔になると樹脂の入り込みを防止できなく、かつ、コンタクトの強度にも問題が生じる。 The connector 1 using the contact structure of the present invention includes a plurality of cylindrical contacts 10 and an insulator 2 on which the contacts 10 are held and arranged, and the insulator 2 is formed by integral molding. 1, the cylindrical contact 10 includes a contact portion 12 that comes into contact with an object, a fixing portion 14 that is held by the insulator 2, and a connection portion 16 that is connected to a cable or a board, and the cylindrical contact A bent prevention wall 20 is provided on the lower surface side between the contact portion 12 and the connection portion 16, and a locking portion 18 is provided on the upper surface side so that the tip of the prevention wall 20 can enter. When the shaped contact 10 is integrally formed with the insulator 2, the prevention wall 20 prevents the resin from going to the contact portion 12 side.
The clearance between the prevention wall 20 of the cylindrical contact 10 and the side walls 24 on both sides is set to 0.03 to 0.05 mm, and the engagement size between the prevention wall 20 and the locking portion 18 is 0.05. -0.1 mm. If the clearance between the prevention wall 20 and the side walls 24 on both sides is 0.03 mm or less, dimensional accuracy at the time of the contact processing is required, which may lead to an increase in cost, and there is a gap between the prevention wall 20 and the side walls 24 on both sides. If it is 0.05 mm or more, the resin cannot be prevented from entering the contact portion 12 side. If the size of engagement between the prevention wall 20 and the locking portion 18 is 0.05 mm or less, the resin pressure during integral molding cannot be withstood, and the engagement between the prevention wall 20 and the locking portion 18 is not possible. If the size of the through hole is 0.1 mm or more, there is a possibility that it becomes a through hole.

図に基づいて本発明のコンタクトの構造について説明する。
次に、前記コンタクト１０について説明する。前記コンタクト１０には、雄型コンタクト１０１と雌型コンタクト１０２とがある。これらの相違点について説明すると、図１にように相手物と接触する接触部１２の形状が違うだけでる。図１（Ａ）のように接触部１２がピン形状をしたものが雄型コンタクト１０１であり、図２（Ｂ）のように接触部１２が２つの接触片により対向するようにソケット形状をしたものが雌型コンタクト１０２である。２種類の前記コンタクト１０はともに略筒状をしている。この２種類のコンタクト１０１、１０２同士は嵌合し合うものであり、その他部分は同様であるため後の説明では雄型コンタクト１０１を例にとって説明する。 The structure of the contact according to the present invention will be described with reference to the drawings.
Next, the contact 10 will be described. The contact 10 includes a male contact 101 and a female contact 102. If these differences are demonstrated, only the shape of the contact part 12 which contacts a partner will be different like FIG. A contact portion 12 having a pin shape as shown in FIG. 1A is a male contact 101, and a socket shape is provided so that the contact portion 12 is opposed by two contact pieces as shown in FIG. 2B. One is the female contact 102. Both of the two types of contacts 10 have a substantially cylindrical shape. The two types of contacts 101 and 102 are fitted to each other, and the other portions are the same, so that the male contact 101 will be described as an example in the following description.

２種類の前記コンタクト１０は金属製であり、公知技術のプレス加工によって製作されている。２種類の前記コンタクト１０の材質としては、寸法安定性や導電性などが要求されるので、黄銅やベリリウム銅やリン青銅等を挙げることができる。２種類の前記コンタクト１０の主な構成部分としては相手物と接触する接触部１２と前記絶縁体２に固定される固定部１４と基板やケーブル等に接続される接続部１６と係止部１８と防止壁２０とを具えている。   The two types of contacts 10 are made of metal and are manufactured by a known press working. As the materials of the two types of the contacts 10, dimensional stability, conductivity, and the like are required, and examples thereof include brass, beryllium copper, and phosphor bronze. The main components of the two types of contacts 10 include a contact portion 12 that comes into contact with a counterpart, a fixing portion 14 that is fixed to the insulator 2, a connection portion 16 that is connected to a substrate, a cable, and the like, and a locking portion 18.

The contact portion 12 is appropriately designed so that the male contact 101 and the female contact 102 can be fitted and a stable contact can be obtained. The fixing portion 14 is a portion fixed to the insulator 16, and is fixed by integral molding in the present invention. The fixing portion 14 may be provided with an arrowhead as in this embodiment in consideration of the holding force when integrally molded. The connecting portion 16 is appropriately designed in consideration of customer specifications, connected items, connection methods, and the like. In this embodiment, the cable is connected to a cable (not shown). The cable is placed on the connection portion 16 having a substantially U shape, and then connected by crimping with a jig or the like (so-called crimping). is doing.

本発明のコンタクト１０では、前記接触部１２と前記接続部１４との間で下面側に、折り曲げられた防止壁２０が設けられている。該防止壁２０によって、一体成型時に樹脂が前記接触部１２側に入り込まないようにしている。また、前記防止壁２０が一体成型時の樹脂圧に耐えられるように、上面側には前記防止壁２０の先端が入る大きさの係止部１８が設けられている。前記防止壁２０と前記係止部１８の形状や大きさは、上記役割を満足するように適宜設計されている。前記係止部１８の形状は、本実施例では凹部形状にした。前記防止壁２０と前記係止部１８の位置は、上記役割や金型の押え位置等を考慮して適宜設計する。押え位置とは、金型で前記コンタクト１０を押える部分であり、即ち、絶縁体２に固定される部分である。   In the contact 10 of the present invention, a bent prevention wall 20 is provided on the lower surface side between the contact portion 12 and the connection portion 14. The prevention wall 20 prevents the resin from entering the contact portion 12 side during integral molding. In addition, a locking portion 18 having a size that allows the tip of the prevention wall 20 to enter is provided on the upper surface side so that the prevention wall 20 can withstand the resin pressure at the time of integral molding. The shape and size of the prevention wall 20 and the locking portion 18 are appropriately designed so as to satisfy the above role. The shape of the locking portion 18 is a concave shape in this embodiment. The positions of the prevention wall 20 and the locking portion 18 are appropriately designed in consideration of the above-mentioned role and the pressing position of the mold. The pressing position is a portion where the contact 10 is pressed by a mold, that is, a portion fixed to the insulator 2.

筒状の前記コンタクト１０の防止壁２０と両側の側壁２４との隙間を０．０３〜０．０５ｍｍにするとともに前記防止壁２０と前記係止部１８との係合する大きさを０．０５〜０．１ｍｍにする。前記防止壁２０と両側の側壁２４との隙間が０．０３ｍｍ以下では前記コンタクト加工時の寸法精度が要求され、コストアップに繋がる恐れがあり、前記防止壁２０と両側の側壁２４との隙間が０．０５ｍｍ以上では樹脂の前記接触部１２側への入り込みを防止できない。前記防止壁２０と前記係止部１８との係合する大きさが０．０５ｍｍ以下では一体成型時の樹脂圧に耐えることができなく、前記防止壁２０と前記係止部１８との係合する大きさが０．１ｍｍ以上では貫通孔になる恐れもあり、貫通孔になると樹脂の入り込みを防止できなく、かつ、コンタクトの強度にも問題が生じる。
即ち、前記防止壁２０と両側の側壁２４との隙間は一体成型時に前記接触部１２側に樹脂が入り込まないようにする重要な部分であり、前記防止壁２０と前記係止部１８との係合する大きさは一体成型時の樹脂圧に耐えうることができ、かつ、一体成型時に前記接触部１２側に樹脂が入り込まないようにする重要な部分である。前記防止壁２０と両側の側壁２４との隙間は理想的には０．０３〜０．０５ｍｍ程度であり、前記防止壁２０と前記係止部１８との係合する大きさは理想的には０．０５〜０．１ｍｍ程度である。 The clearance between the prevention wall 20 of the cylindrical contact 10 and the side walls 24 on both sides is set to 0.03 to 0.05 mm, and the engagement size between the prevention wall 20 and the locking portion 18 is 0.05. -0.1 mm. If the clearance between the prevention wall 20 and the side walls 24 on both sides is 0.03 mm or less, dimensional accuracy at the time of the contact processing is required, which may lead to an increase in cost, and there is a gap between the prevention wall 20 and the side walls 24 on both sides. If it is 0.05 mm or more, the resin cannot be prevented from entering the contact portion 12 side. If the size of engagement between the prevention wall 20 and the locking portion 18 is 0.05 mm or less, the resin pressure during integral molding cannot be withstood, and the engagement between the prevention wall 20 and the locking portion 18 is not possible. If the size of the through hole is 0.1 mm or more, there is a possibility that it becomes a through hole.
In other words, the gap between the prevention wall 20 and the side walls 24 on both sides is an important part that prevents the resin from entering the contact portion 12 side during integral molding, and the engagement between the prevention wall 20 and the locking portion 18. The size that can be combined is an important part that can withstand the resin pressure during integral molding and that prevents the resin from entering the contact portion 12 side during integral molding. The gap between the prevention wall 20 and the side walls 24 on both sides is ideally about 0.03 to 0.05 mm, and the size of the engagement between the prevention wall 20 and the locking portion 18 is ideal. It is about 0.05 to 0.1 mm.
