【考案の詳細な説明】
本考案は電気接続に使用される雌接触子の構造に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a female contact used in electrical connections.
最近、自動車等の電気配線にはゴムやプラスチック等の
絶縁成型品の外殻にばね性のある導電性板材より形成さ
れた接触子を組込んだコネクタが多く用いられている。2. Description of the Related Art Recently, many connectors have been used for electrical wiring in automobiles and the like, in which contacts made of a springy conductive plate are incorporated into an outer shell of an insulating molded product such as rubber or plastic.
しかしそのようなコネクタは、外殻の材料の性質上″こ
じり″に大変器いため接触子の相互嵌合時にこじり力を
受けると雌接触子が変形して接触不良を起しやすいとい
う問題がある。However, such connectors have the problem that, due to the nature of the material of the outer shell, it is very difficult to "pry" the connectors, so that if the contacts are subjected to prying force when they are mated together, the female contacts may deform and cause poor contact. .
こ0点に鑑み従来(′!S例えばゴム製外殻品の場合に
は第1図に示すように、雌接触子1に単一材料で製作さ
れた合わせ目のないスリーブ2を被せ(このスリーブを
被せた状態を鎖線で示してあム)、固着し、接触片3,
4の開きすぎを防止する構造が採用されている。In view of this point, in the case of a rubber shell product, for example, the female contact 1 is covered with a seamless sleeve 2 made of a single material, as shown in Figure 1. The state in which the sleeve is covered is shown by the chain line (A), and the contact piece 3 is fixed.
A structure is adopted that prevents the opening of 4 from opening too much.
しかしこの構造では、雌接触子1とスリーブ2との二体
構造で三部品を組合わせる必要がある上にスリーブ2を
製造するには1′しぼり”鍛造”等の加工を施さねばな
らないため、加工や組立においてわずられしい点が多い
。However, with this structure, it is necessary to combine three parts into a two-piece structure of the female contact 1 and the sleeve 2, and in order to manufacture the sleeve 2, processing such as 1' squeeze "forging" must be performed. There are many issues with processing and assembly.
従って本考案の目的は、製造が簡単でかつ耐こじり性に
優れた雌接触子を提供することにある。Therefore, an object of the present invention is to provide a female contact that is easy to manufacture and has excellent kink resistance.
以下第2図以降を参照しながら本考案につき実施例を用
いて説明する。The present invention will be described below using examples with reference to FIG. 2 and subsequent figures.
第2図は本考案の一実施例を示したもので、この雌接触
子は第3図に展開図で示した如き形状で且つばね性を有
する導電性平板部材10から作られている。FIG. 2 shows an embodiment of the present invention, and this female contact is made of a conductive flat plate member 10 having a shape as shown in a developed view in FIG. 3 and having spring properties.
即ち平板部材10には長手方向一端近傍の一辺11に突
起部12を有するキー13を形成し、他辺14には重ね
部15を設けるとともに重ね部Q近傍部分に窓16を設
け、かつ両方の辺11及び14の中間部分に切込み17
を入れてばね片18を形成させる。That is, the flat plate member 10 is provided with a key 13 having a protrusion 12 on one side 11 near one end in the longitudinal direction, an overlapping portion 15 on the other side 14, and a window 16 in the vicinity of the overlapping portion Q. Cut 17 in the middle of sides 11 and 14
to form the spring piece 18.
そして両方の辺11及び14が互いに対向するように平
板部材10を丸め、その際重ね部15を一辺11の近傍
部分の内側に重ねるとともにキー13を窓16内に挿入
するが、その場合、第4図の如く10の一端からキー1
3の側面Aまでの距離t1と、同じく10の一端から窓
16の側面Bまでの距離t2とは略等しく、かつ突起部
12の先端は側面Aからt3だげ突出しており更に窓1
6の長手方向の全長t4はキー13の全長t5よりも僅
かに大きいのみであるから、例えば平板部材10を丸め
加工しつつキー13を窓16内に挿入しながら押圧する
と、窓16の側面BVc突起部12の斜面部Cが当接し
、上記押圧力をF、とすると分力F2が生ずるから一辺
11はD方向にずれ、該ずれがt3と等しくなったとき
にキー13は窓16内に完全に挿入されるとともに一辺
11は他辺14と衝合する。Then, the flat plate member 10 is rolled up so that both sides 11 and 14 face each other, and at this time, the overlapping part 15 is overlapped inside the vicinity of one side 11, and the key 13 is inserted into the window 16. 4 As shown in the figure, press key 1 from one end of 10.
The distance t1 from the side surface A of the window 16 to the side surface A of the window 16 is approximately equal to the distance t2 from one end of the window 16 to the side surface B of the window 16.
Since the total length t4 in the longitudinal direction of the key 13 is only slightly larger than the total length t5 of the key 13, for example, when the flat plate member 10 is rounded and the key 13 is inserted into the window 16 and pressed, the side surface BVc of the window 16 When the inclined surface C of the protrusion 12 comes into contact and the above-mentioned pressing force is F, a component force F2 is generated, so one side 11 shifts in the direction D, and when the shift becomes equal to t3, the key 13 moves into the window 16. When completely inserted, one side 11 abuts the other side 14.
そしてF2がなくなるから弾性により一辺11は逆り方
向に戻りキー13の側面Aと窓16の側面Bとが衝合し
、キーの突起部12が他辺140重ね部15の内側部分
に係合するからその状態で一辺11は他辺14と離れる
ことはない。Then, since F2 disappears, one side 11 returns to the opposite direction due to elasticity, and the side surface A of the key 13 and the side surface B of the window 16 abut each other, and the protrusion 12 of the key engages with the inside part of the other side 140 and the overlapping part 15. Therefore, in this state, one side 11 will not be separated from the other side 14.
またばね片18は、平板部材を丸めたときの内側に少し
突出するように曲げるとともにこのばね片18の両側の
点線で不した部分を第5図℃示したように同じく内側に
押し出させてダボ19及び19′を形成する。In addition, the spring piece 18 is bent so that it slightly protrudes inward when the flat plate member is rolled up, and the portions of the spring piece 18 not shown by the dotted lines on both sides are similarly pushed out and doweled. 19 and 19' are formed.
こうして第2図に示したように雄接触子を受は入れる円
筒部20、コネクタノ・ウジングに保持させるための保
持部21、および電線の心線を圧着するための結線部2
2を有する雌接触子が得られる。Thus, as shown in FIG. 2, there is a cylindrical portion 20 for receiving the male contact, a holding portion 21 for holding the connector housing, and a connection portion 2 for crimping the core wire of the electric wire.
A female contact with 2 is obtained.
このような雌接触子の円筒部20内に第5図及び第6図
に示すように雄接触子23を挿入すると、ばね片18が
該雄接触子に弾性接触することにより両者の電気的接続
が得られるが、このときの雄接触子23の挿入を容易に
するためばね片18の先端は丸みをもって外側へ少し曲
げられている。When the male contact 23 is inserted into the cylindrical portion 20 of such a female contact as shown in FIGS. 5 and 6, the spring piece 18 comes into elastic contact with the male contact, thereby establishing an electrical connection between the two. However, in order to facilitate the insertion of the male contact 23 at this time, the tip of the spring piece 18 is rounded and slightly bent outward.

がばね片18を変形させる方向に大きくこじられた場合
にはそれらのダボ19 、19’が雄接触子23を受け
ることによってばね片18の過大変形を防止する。In the female contact having the above-described structure, although the flat plate member 10 is rolled up to form the cylindrical portion 20, the key 13 is inserted into the window 16 and the protrusion 12 engages with the inner portion of the overlapped portion 15. Therefore, even if a prying force is applied to the male contact 23 inserted into the cylindrical portion 20, the seam 24 will not open, and there are dowels 19 and 19'75 on both sides of the spring piece 18. Since it is made up of male contacts 23
When the spring pieces 18 are significantly twisted in a direction that causes the spring pieces 18 to deform, the dowels 19 and 19' receive the male contacts 23 to prevent the spring pieces 18 from being excessively deformed.

は・・ンダ付構造にしてもよい。The shapes of the spring piece 18 and the holding part 21 are not limited to the illustrated embodiment, and various modifications are possible.
