本考案は、ケーブル芯線を各接触子へハンダ付
けした後に、そのハンダ付け部位を樹脂成形し
て、コネクタ本体を完成させるようにした、ケー
ブル付コネクタの接触子保持体に関する。[Detailed description of the invention] This invention is a contact holder for a connector with a cable, in which the cable core wire is soldered to each contact, and then the soldered part is molded with resin to complete the connector body. Regarding.
従来のコネクタは、コネクタ単体として完成さ
れたものを、使用に際して、ケーブルの各芯線を
ハンダ付け等により接続していた。 Conventional connectors are completed as a single connector, and each core wire of the cable is connected by soldering or the like when used.
しかし最近は、電気システムの信頼性の向上が
望まれるに至り、コネクタの芯線接続部の信頼性
の向上が要求され、環境条件、並びに機械的強度
等の観点から、芯線接続部を樹脂で固定するとと
もに、ケーブルとコネクタの連結部に、樹脂成形
による可撓性ベント部を備えたケーブル付コネク
タが要望されるようになつた。 However, recently, there has been a desire to improve the reliability of electrical systems, and there is a demand for improved reliability of the core wire connection part of connectors, and from the viewpoint of environmental conditions and mechanical strength, the core wire connection part is fixed with resin. At the same time, there has been a demand for connectors with cables that are provided with a flexible vent section formed by resin molding at the connecting section between the cable and the connector.
しかし、従来のコネクタ単体として完成された
コネクタは、軸脂成形に際しての芯線周囲並びに
ハンダ付け部の樹脂の流れ等が考慮されておら
ず、そのため、特に小形多芯コネクタにおいて
は、樹脂成形に際して、筒線の完全断線もしく
は、部分断線を生じるとともに、芯線に引張り力
の残留応力を生じる。 However, conventional connectors completed as single connectors do not take into consideration the flow of resin around the core wire and around the soldering part when molding the shaft fat, and therefore, especially in small multi-core connectors, when molding the resin, This causes complete or partial disconnection of the cylindrical wire, and generates tensile residual stress in the core wire.
特に、芯線が撚線の場合の部分断線は、電気的
試験によつて発見することが困難で、実質的には
不良品が、良品とされてしまう欠点がある。 Particularly, when the core wire is a stranded wire, it is difficult to detect a partial wire breakage by an electrical test, and there is a drawback that a product that is actually defective is considered to be a good product.
また、残留応力が芯線に加わつた場合に、ケー
ブルを曲げたとき、断線を生じる欠点がある。 Additionally, there is a drawback that if residual stress is applied to the core wire, the cable may break when the cable is bent.
さらに、従来のコネクタ単体として完成された
形式の多芯コネクタは、雌雄いずれか一方の接触
子保持に、各接触子がそれぞれに自動的に求心し
得る緩みが設けられ、それにより、雌雄結合時の
各接触子相互の芯出しを容易とするようにしてあ
るが、この形式のコネクタのハンダ付け部を樹脂
で固めると、緩みが固定されて自動求心作用がな
くなり、そのため、樹脂成形の際に治具等によつ
て、精密な芯出しを行なわなければならない欠点
がある。 Furthermore, in the conventional multi-conductor connector, which has been completed as a single connector, a slack is provided in the retainer of either the male or female contact so that each contact can be automatically centered on each other, so that when the male and female are connected, This makes it easy to center each contact between each other, but if the soldered parts of this type of connector are hardened with resin, the looseness will be fixed and the automatic centripetal action will be eliminated. There is a drawback that precise centering must be performed using a jig or the like.
また、従来の多芯コネクタは、芯線を接続する
ハンダ付け部が、すべて同一平面に並べられ、か
つハンダ付け方向が、隣接するものと同一方向を
向き、ハンダ付けに熟練を要して作業性が悪く、
しかも、ハンダ付け処理を行なつた接続部は余剰
ハンダによつて径を増し、樹脂成形に際しての狭
窄部を作り、その狭窄部においては、樹脂の流れ
が速くなつて、芯線を引き込むような欠点があ
る。 In addition, in conventional multi-conductor connectors, the soldering parts that connect the core wires are all arranged on the same plane, and the soldering direction is the same as that of the adjacent ones, which makes soldering difficult and requires skill. is bad,
Moreover, the diameter of the soldered connection increases with excess solder, creating a constriction during resin molding, and in the constriction, the flow of resin becomes faster and the core wire is drawn in. There is.

要の形状に成形される。 Contactor 2 to contactor holder 1 according to the above-mentioned present invention
In the state in which the cable 17 is held, each core wire 19 of the cable 17 is connected to the solder 2 to the exposed connection part 2b at the rear end.
0, and the cable 17 is fixed in the axial direction by the cable retaining member 18, and then the cable 17 is soldered with a soft resin material 21 having a lower melting temperature than the resin of the above-mentioned structural member, for example,
Polyacetal resin with a deformation temperature of 120℃ at a molding temperature of around 190℃, or a deformation temperature of around 180℃ at a molding temperature of around 180℃.
The rear part of the contact part holder 3 from the base part 5 is molded into a desired shape including a flexible vent part using 80 DEG C. vinyl chloride resin or the like.

じることはない（第８，９図参照）。 Furthermore, when soldering the core wire 19, since the solder reservoir grooves 12 are provided on both sides of the exposed connection part 2b, a large amount of leeway can be obtained in adjusting the amount of solder supplied during the soldering work, and Therefore, poor soldering due to insufficient solder and short circuit between adjacent connecting portions 2b due to excessive solder will not occur (see FIGS. 8 and 9).
以上は、接触子２の数が比較的少ない５本の場
合の実施例であるが、第６図に示す12本、第７図
に示す10本等の場合には、接触部２ｂの露出方向
が考慮される。 The above is an example in which the number of contacts 2 is relatively small, 5, but in the case of 12 as shown in FIG. 6, 10 as shown in FIG. 7, etc., the direction in which the contact portion 2b is exposed is taken into account.
すなわち、接触子２の数が増加すると、接触子
２の配列が、同心円配列では、第６図の如く、２
重層となり、また、行列配列では、第７図の如く
多段層とする必要がある。 That is, when the number of contacts 2 increases, the arrangement of contacts 2 becomes 2 as shown in FIG. 6 in a concentric arrangement.
In addition, in a matrix arrangement, it is necessary to have multiple layers as shown in FIG.
そこで、樹脂材２１の成形に際しての狭窄部を
できるだけ少なくするためと、ハンダ付け作業を
容易とするために、各接触子２′，２″の接続部２
b′，２b″の露出方向を、軸線と直交する同一平面
で、その露出方向が重ならないように、外向きに
露出するようにしてある。なお、図中、前記説明
と同一部分を表わす符号には′又は″を付設して示
す。 Therefore, in order to minimize the narrowing portion when molding the resin material 21 and to facilitate the soldering work, the connecting portion 2 of each contactor 2', 2''
The exposed directions of b' and 2b'' are on the same plane perpendicular to the axis and are exposed outward so that the exposed directions do not overlap.In the figure, the same parts as in the above description are denoted by the reference numerals. is indicated by adding ' or ''.
例えば、第６図の同心配列の実施例では、中心
層に配列された接触子２′の接続部２b′を、その
外側の層の接続部２b′より露出長に相当する分だ
け長くしておき、接続部２b′の露出部分が各層毎
に段差をもつようにする。 For example, in the concentric arrangement embodiment shown in FIG. 6, the connecting portions 2b' of the contacts 2' arranged in the center layer are made longer than the connecting portions 2b' of the outer layers by an amount corresponding to the exposed length. so that the exposed portion of the connecting portion 2b' has a step difference for each layer.
また、第７図の多段層の配列の実施例では、同
様に、中央段の接続部２b″を次段の接続部２
b″より露出長分だけ長くしておき、各段毎に、
段差を設けるようにしてある。 In addition, in the embodiment of the multi-layered arrangement shown in FIG.
Make it longer than b″ by the exposure length, and for each step,
It is designed to have a step.
なお、行列配列の場合は、一方の外側の段から
他方の外側の段に向けて、順次階段状に段差を設
けることもある。 In the case of a matrix arrangement, steps may be sequentially provided in a stepwise manner from one outer step to the other outer step.

が高められる。 The present invention described above is especially effective when applied to small multi-core connectors.In the case of small multi-core connectors, the soldering work becomes more precise and requires more skill in the solder supply during soldering work. In other words, in the present invention, the excess amount of supplied solder is absorbed by the solder reservoir groove, so that work efficiency is improved and the reliability of the soldering portion is also increased.

る等、多大の利点がある。 In addition, even though a large number of ultra-fine core wires are intertwined, the core is embedded in a pre-molded connection holder, so resin can be injected easily during the final resin molding. can be done. Therefore, there are many advantages such as not applying tension to the core wire, improving reliability, and increasing productivity by increasing resin injection pressure and injection speed compared to conventional methods.
