【考案の詳細な説明】 この考案はコネクタの接触子に関し、更に詳細に云えば
外殻に対する係止構造を有し、導電性板材を折曲げ刀目
工して製作する接触子に関するものである。[Detailed description of the invention] This invention relates to a contact for a connector, and more specifically to a contact that has a locking structure for the outer shell and is manufactured by bending a conductive plate material. .

第１図は防水コネクタの一部を切断した斜視図である。FIG. 1 is a partially cut away perspective view of the waterproof connector.

このコネクタは外殻１０１と接触子１とで構成されてい
る。This connector is composed of an outer shell 101 and a contact 1.

外殻１０１は軟質ゴム等の絶縁物で作られていて、接触
子１を外から被覆して防水構造としている。The outer shell 101 is made of an insulating material such as soft rubber, and covers the contactor 1 from the outside to provide a waterproof structure.

接触子１は、円筒部３、フランジ４、係止部９および結
線部８より或っており、また結線部８は電線の心線なモ
着保持して電気的接続を保つ心線正着部６と電線の被覆
を保持して電線を抜けないようにしている電線被覆圧着
部７で構成されている。The contactor 1 consists of a cylindrical part 3, a flange 4, a locking part 9, and a connection part 8, and the connection part 8 is a core-fitting part that holds the core of the wire to maintain electrical connection. It consists of a wire covering crimping part 6 and a wire covering crimping part 7 which holds the covering of the wire and prevents the wire from coming off.

係止部９は円筒部３、フランジ４より直径が小さく、外
殻１０１に設けた凸部１０２で保持されて接触子の抜は
止めとなっている。The locking portion 9 has a smaller diameter than the cylindrical portion 3 and the flange 4, and is held by a convex portion 102 provided on the outer shell 101 to prevent the contact from being removed.

この接触子１を作る場合、第２図のような形状に金属板
を打抜き、これをプレスによって成形して円筒状にして
いる。When making this contactor 1, a metal plate is punched out in the shape shown in FIG. 2, and then pressed into a cylindrical shape.

覆圧着部材７ａで構成されている。This plate material is a cylindrical member 3a forming the cylindrical portion 3 of the contactor 10.
, a locking member 9a that forms the locking portion 9, a flange member 4a that forms the flange 4, and a wire connection member 8a that forms the connection portion 8.The wire connection member 8a further includes a core wire crimping member 6a that creates the core wire crimping portion 6, and a wire connection member 8a that creates the wire connection portion 6. It is composed of a wire covering crimping member 7a that forms the wire covering crimping section 7.

円筒部材３ａには第２図のように切欠きを起してバネ５
を作り相手方接触子との接触を行なわせる。A notch is formed in the cylindrical member 3a as shown in FIG.
to make contact with the other party's contactor.

第１図で明らかなように、この接触子１０円筒部３、フ
ランジ４および係止部９は円ノーヨ筒であるが、第２図
の板材をプレス成形して接触子１を作るのは、係止部９
が前記円筒部３およびフランジ４に比して直径が小さく
、しかも係止部材９ａが他の部分と同一平面にあるので
実際には極めて困難で、いわゆる無理な成形をしており
、従って寸法精度を良くするのはむずかしく、曲りを生
ずる等の難点があるうえ、成形後に皺が入ったり、割れ
を生ずる惧れがある。As is clear from FIG. 1, the cylindrical portion 3, flange 4, and locking portion 9 of the contact 10 are circular cylinders, but the contact 1 is made by press-forming the plate material shown in FIG. Locking part 9
is smaller in diameter than the cylindrical portion 3 and flange 4, and the locking member 9a is on the same plane as the other portions, so it is actually extremely difficult to form, and the dimensional accuracy is therefore poor. It is difficult to improve the quality, and there are problems such as bending, and there is a risk that wrinkles or cracks may occur after molding.

本考案の目的は上記の欠点を除き、成形が容易で寸法精
度が良く、曲り、皺、割れ等のない接触子を提供するこ
とである。The object of the present invention is to eliminate the above-mentioned drawbacks and provide a contact that is easy to mold, has good dimensional accuracy, and is free from bends, wrinkles, cracks, etc.

以下に本考案の実施例を図面によって説明する。Embodiments of the present invention will be described below with reference to the drawings.

第３図は本考案による接触子の展開された板材を示す。FIG. 3 shows an expanded plate of a contactor according to the present invention.

本考案では係止部材９ａにスリット１０を複数個例えば
ｎ−１個設けると残部はｎ個の連結部１１となる。In the present invention, if a plurality of slits 10, for example n-1, are provided in the locking member 9a, the remaining portions become n connecting portions 11.

その他の部分は略々同じであるが、成形後連結部１１０
両端に後述の空間部１２を作るために多少形が変ってい
る。The other parts are almost the same, but the connecting part 110 after molding.
The shape has been changed somewhat to create spaces 12, which will be described later, at both ends.

このような構造の板材を成形した接触子を第４図に示す
。FIG. 4 shows a contact formed from a plate material having such a structure.

図より明らかなように前記板材の連結部１１は円筒部材
３ａおよびフランジ部材４ａとの接触部で折曲げられて
柱状部１３を形成し、スリット１０および係止部材９ａ
の両端の切込みによって作られた空間部１２と併せて係
止部９を構成する。As is clear from the figure, the connecting portion 11 of the plate material is bent at the contact portion with the cylindrical member 3a and the flange member 4a to form a columnar portion 13, and the slit 10 and the locking member 9a
Together with the space 12 created by the cuts at both ends, the locking part 9 is formed.

折曲げに当ってはスリット１０があるため連結部１１を
折曲げて柱状部１３を成形するのは容易である。When bending, since the slit 10 is present, it is easy to bend the connecting portion 11 to form the columnar portion 13.

すなわち成形された係止部９の空間部１２０間隙は前記
円筒部３およびフランジ４の接続部で広く、柱状部１３
の中間部で狭くなっており、従来例である第２図の板材
の係止部材９ａの部分は連続した板であるため逃げがな
く、成形に無理を生じ、皺を生じたり、寸法精度を思う
ように出すことが出来なかったのに比べて、本考案によ
るスリット１０を設けた第３図の板材では、前記空間部
１２で既述のように間隙の差が生じて逃げが出来るので
成形に無理がなく、皺を生ずることなく良い寸法精度で
直径の細い係止部９が成形されるものである。That is, the space 120 gap of the molded locking part 9 is wide at the connection part of the cylindrical part 3 and the flange 4, and
Since the locking member 9a of the conventional plate shown in FIG. 2 is a continuous plate, there is no relief, which causes strain in the molding, causes wrinkles, and impairs dimensional accuracy. In contrast, in the plate material shown in FIG. 3 with the slits 10 according to the present invention, there is a difference in the gap in the space 12 as described above, which allows for escape, so it is easier to form the material. The locking portion 9 having a small diameter can be formed with good dimensional accuracy without undue stress and without causing wrinkles.

第４図では雌接触予め例を示したが、雄接触子を成形す
る場合も同様に加工出来る。Although FIG. 4 shows an example of a female contact, the same process can be performed when molding a male contact.

また寸法精度を良くすることが容易であるため雌雄接触
子の嵌合は円滑に行なうことが出来る。Furthermore, since it is easy to improve dimensional accuracy, the male and female contacts can be fitted together smoothly.

更に第５図において、外殻１０１ａとそれに包まれた雌
接触子１から成る雌コネクタ１４と外殻１０１ｂとそれ
に包まれた雄接触子２かも成る雄コネクタ１５を嵌合さ
れる場合、それぞれの外殻１０１ａと外殻１０１ｂとに
心ずれがあったとしても、前述のように係止部９の柱状
部１３は分離されたｎ個の連結部１１によって構成すれ
ており、個々のｍ部片かばね作用を持っていて曲がるの
で容易に嵌合することが出来る。Furthermore, in FIG. 5, when a female connector 14 consisting of an outer shell 101a and a female contact 1 enclosed therein and a male connector 15 consisting of an outer shell 101b and a male contact 2 enclosed therein are connected, each Even if there is misalignment between the outer shell 101a and the outer shell 101b, the columnar part 13 of the locking part 9 is composed of n separate connecting parts 11, as described above, and the m pieces of each Since it has a spring action and bends, it can be easily fitted.

第６図に本考案の他の実施例を示す。FIG. 6 shows another embodiment of the present invention.

これは係止部９を成形するのに連結部１１を逆に外に突
出させて成形した例であって、第１図における外殻１０
１に設けた凸部１０２を上記の係止部９に適合した凹部
として係止させるものである。This is an example in which the connecting part 11 is conversely projected outward when molding the locking part 9, and the outer shell 10 in FIG.
The convex portion 102 provided in the above-mentioned locking portion 1 is locked as a recessed portion adapted to the locking portion 9 described above.

なお円筒部３の形状は図示の実施例に限ることなく各種
の変形が可能で例えば角筒状でもよい。Note that the shape of the cylindrical portion 3 is not limited to the illustrated embodiment, and can be modified in various ways, for example, may be in the shape of a rectangular tube.

以上のように本考案によれば一枚の板材から直径の異な
る同心円筒を容易にかつ正確な寸法で作ることが出来、
製品は曲り、皺、割れ等がなく、更に雌雄接触子の嵌合
も容易にすることが出来るなど、利点が極めて大きい。As described above, according to the present invention, concentric cylinders with different diameters can be easily made from a single plate with accurate dimensions.
The product has many advantages, such as being free from bends, wrinkles, and cracks, and also making it easier to fit male and female contacts together.
