Description

本発明は、雌側端子金具に関するものである。   The present invention relates to a female terminal fitting.

図１１には、特開平１０−１８９１０２号公報に開示された雌側端子金具１００を示した。この雌側端子金具１００の前方（図示左側）には、筒状の接続部１０１が設けられており、その接続部１０１の内部には、図示しない相手側の雄タブに対して弾性的に接触する弾性接触片１０２が設けられている。弾性接触片１０２は、その基端部が接続部１０１の上面側に設けられており、そこから後方に延出された後に、下方に向かって弧状に湾曲されて、下面側後部から再び前方に向かって延出するようにして構成されている。ところが、この構成では、接続部１０１の内部空間内を前後方向に向かう光線は、弾性接触片１０２によって遮られてしまうために、弾性接触片１０２と上面側の接触部１０３との離間距離を赤外線によって測定することができない。そこで、弾性接触片の基端部を接続部の下面側後方に設け、そこから前方に向かって先端部を延出させる改良タイプの雌側端子金具が開発されている。
特開平１０−１８９１０２号公報 FIG. 11 shows a female terminal fitting 100 disclosed in Japanese Patent Laid-Open No. 10-189102. A cylindrical connecting part 101 is provided in front of the female terminal fitting 100 (left side in the figure), and the inside of the connecting part 101 is elastically contacted with a male tab on the other side (not shown). An elastic contact piece 102 is provided. The elastic contact piece 102 has a base end portion provided on the upper surface side of the connection portion 101, and extends rearward from the elastic contact piece 102. Then, the elastic contact piece 102 is curved downward in an arc shape and forwards again from the lower surface side rear portion. It is configured to extend toward the front. However, in this configuration, since the light rays traveling in the front-rear direction in the internal space of the connecting portion 101 are blocked by the elastic contact piece 102, the separation distance between the elastic contact piece 102 and the contact portion 103 on the upper surface side is set to infrared rays Cannot be measured by. In view of this, an improved type female terminal fitting has been developed in which the base end portion of the elastic contact piece is provided on the rear side of the lower surface side of the connection portion, and the distal end portion is extended forward therefrom.

ところで、近年には特にコネクタ及び雌側端子金具の小型化が進んでいる。小型化された雌側端子金具では、折曲げ加工前の金属板材の厚みも薄くなり、かつ折曲げ工程における精度誤差に対する許容幅が微小となるために、従来の大きさの雌側端子金具では問題とされなかった点が新たに問題となることがある。例えば上記の改良タイプの雌側端子金具では、弾性接触片の基端部分が下面の所定位置に折り付けられたときに、板材の弾性によって僅かに浮き上がることがある。従来の大きさの雌側端子金具では、その程度の浮き上がりでは問題とならない場合でも、雌側端子金具の小型化に伴って、規格から外れてしまうことがあり得る。
本発明は、上記した事情に鑑みてなされたものであり、その目的は、小型化された雌側端子金具においても、弾性接触片の基端部分の浮き上がりを規制できる雌側端子金具を提供することにある。 By the way, in recent years, miniaturization of connectors and female terminal fittings has been progressing. With the downsized female terminal fitting, the thickness of the metal plate before bending is reduced and the tolerance for accuracy error in the bending process is very small. Points that were not considered a problem may become a new problem. For example, in the above-described improved type female terminal fitting, when the base end portion of the elastic contact piece is folded at a predetermined position on the lower surface, it may be slightly lifted by the elasticity of the plate material. Even if the female terminal fitting of the conventional size does not cause a problem when it is lifted to such an extent, it may fall out of the standard as the female terminal fitting is downsized.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a female terminal fitting that can regulate the lifting of the base end portion of the elastic contact piece even in a downsized female terminal fitting. There is.

図２に示すように、雌側端子金具１を形成するための端子形成用板材１０は、一枚の伝導性板材をプレスする事によって、帯状片２７に対して所定の間隔で連結された状態で形成される。雌側端子金具１の製造手順を簡単に説明すると次のようである。
端子形成用板材１０が帯状片２７に接続されている状態で、所定の折曲げ線２８（図２中の下側の板材１０に点線で示す。なお、実際の板材１０は、図２中上側の板材１０のようであり、折曲げ線２８が設けられているわけではない。）に沿って、所定の手順で折曲げ加工が行われる。そして、雌側端子金具１が形成されたのちに、各雌側端子金具１が帯状片２７から切り離される。 In the bottom wall portion 23, a contact avoidance window 24 is opened at a position corresponding to the lower side of the distal end portion 9 </ b> B of the elastic contact piece 9. When the elastic contact piece 9 is elastically deformed downward, the distal end portion 9B is fitted into the contact avoidance window 24, whereby the elastic deformation of the elastic contact piece 9 is increased.
As shown in FIG. 2, the terminal forming plate 10 for forming the female terminal fitting 1 is connected to the strip 27 at a predetermined interval by pressing one conductive plate. Formed with. The manufacturing procedure of the female terminal fitting 1 will be briefly described as follows.
In a state in which the terminal forming plate 10 is connected to the strip 27, a predetermined fold line 28 (shown by a dotted line on the lower plate 10 in FIG. 2) is shown in FIG. And the folding line 28 is not provided.) Is bent in a predetermined procedure. Then, after the female terminal fitting 1 is formed, each female terminal fitting 1 is separated from the strip-shaped piece 27.

板材１０において、弾性接触片９は略Ｉ形状とされている。弾性接触片９の基端部９Ａからは、側方（図２においては、下方）に向かって係止縁２５が突設されている。この係止縁２５は、雌側端子金具１を折曲げ加工する間に、一方側の側壁部１５及び底壁部２３に連続して設けられている係止孔２６に嵌まり込むようになっている。
また、接続部５の上面後端において、一方側の側縁には、スタビライザ１１が突設されている。このスタビライザ１１は、雌側端子金具１が端子収容室２１に収容されるときに、端子収容室２１の上壁部分に凹設された溝部（図示せず）に嵌まり込むことで、雌側端子金具１の上下方向を規定すると共に、雌側端子金具１装着後の姿勢の安定に寄与する。 In the plate member 10, the elastic contact piece 9 has a substantially I shape. A locking edge 25 projects from the base end portion 9A of the elastic contact piece 9 toward the side (downward in FIG. 2). While the female terminal fitting 1 is bent, the locking edge 25 is fitted into a locking hole 26 that is continuously provided in the side wall portion 15 and the bottom wall portion 23 on one side. ing.
A stabilizer 11 projects from the side edge on one side at the rear end of the upper surface of the connecting portion 5. When the female terminal fitting 1 is accommodated in the terminal accommodating chamber 21, the stabilizer 11 is fitted into a groove (not shown) recessed in the upper wall portion of the terminal accommodating chamber 21, so that the female side It defines the vertical direction of the terminal fitting 1 and contributes to the stability of the posture after the female terminal fitting 1 is mounted.

また、上面壁部１２の中央には、窓部１６が切り欠かれており、その前端縁には、コネクタ３に設けられた樹脂ランス１３に係合する係合部１４が突設されている。
次に、上記のように構成された本実施形態の作用および効果について説明する。
端子形成用板材１０が折曲げ加工用装置（図示せず）の内部を通る間に、所定の折曲げ線２８に沿うようにして折曲げ加工が行われて、雌側端子金具１が製造される。その折曲げ加工の間に、略角筒状の接続部５が組み立てられるが、その工程中には、係止縁２５が係止孔２６に嵌まり込むことによって、弾性接触片９の基端部９Ａの位置決めがなされている。 A window portion 16 is cut out at the center of the top wall portion 12, and an engaging portion 14 that engages with a resin lance 13 provided on the connector 3 protrudes from the front edge of the window portion 16. .
Next, the operation and effect of the present embodiment configured as described above will be described.
While the terminal forming plate 10 passes through the inside of the bending apparatus (not shown), bending is performed along a predetermined folding line 28, and the female terminal fitting 1 is manufactured. The During the bending process, the connection portion 5 having a substantially rectangular tube shape is assembled. During the process, the locking edge 25 is fitted into the locking hole 26, so that the base end of the elastic contact piece 9 is obtained. The part 9A is positioned.

こうして製造された雌側端子金具１は帯状片２７から切り離された後に、予め端部の被覆を剥ぎ取った電線２が雌側端子金具１の後部上面側に載置され、両バレル７、８をかしめ付けることによって、電線２と雌側端子金具１とを接続しておく。
次に、コネクタ３の端子挿入口２０から雌側端子金具１の先端側を端子収容室２１に挿入し、正規の組付位置まで押し込むことにより、ランス１３が係合部１４に対して弾性的に係合することによって、雌側端子金具１が端子収容室２１の内部に抜止保持される。その後、リテーナ２２を本係止位置に押し込むと、リテーナ２２が雌側端子金具１の連結部６に嵌まり込むことにより、雌側端子金具１が二重に抜け止めされる。また、雄タブ４が挿入されると、図１０に示すように、両接触部９Ｃ，１８が雄タブ４を挟持しつつ接触する。 After the female terminal fitting 1 manufactured in this way is cut off from the strip-shaped piece 27, the electric wire 2 from which the coating of the end portion has been peeled off in advance is placed on the rear upper surface side of the female terminal fitting 1, and both barrels 7, 8 The electric wire 2 and the female terminal fitting 1 are connected by caulking.
Next, the distal end side of the female terminal fitting 1 is inserted into the terminal accommodating chamber 21 from the terminal insertion port 20 of the connector 3 and pushed into a proper assembly position, so that the lance 13 is elastic with respect to the engaging portion 14. By engaging with the female terminal fitting 1, the female terminal fitting 1 is retained in the terminal accommodating chamber 21. Thereafter, when the retainer 22 is pushed into the final locking position, the retainer 22 is fitted into the connecting portion 6 of the female terminal fitting 1, so that the female terminal fitting 1 is prevented from coming off twice. Further, when the male tab 4 is inserted, as shown in FIG. 10, both contact portions 9 </ b> C and 18 come into contact with each other while holding the male tab 4.

このように本実施形態によれば、基端部９Ａと側壁部１５との間に設けられた係止縁２５と係止孔２６とが、弾性接触片９の基端部９Ａを係止することで位置決めをするので、弾性接触片９の基端部分の浮き上がりを規制できる。このため、特に小型化された雌側端子金具１であっても、良好に規格を満たすことができる。   Thus, according to this embodiment, the locking edge 25 and the locking hole 26 provided between the base end portion 9A and the side wall portion 15 lock the base end portion 9A of the elastic contact piece 9. Therefore, the lifting of the base end portion of the elastic contact piece 9 can be restricted. For this reason, even if the female terminal fitting 1 is particularly miniaturized, the standard can be satisfactorily satisfied.

また、雌側端子金具１を折曲げ加工するときに、基端部９Ａから突設された係止縁２５が、側壁部１５に設けられた係止孔２６に嵌まり込むことにより、弾性接触片９の基端部９Ａの位置決めがなされる。このため、例えば、側壁部１５の一部を切り起こして、その内側部分を基端部９Ａの上面に折り付ける構成の係止部を設けた場合に比べると、加工の手間が少なくて済む。
また、接続部５は、前後両方向に開放する筒状とされているので、雌側端子金具１において、両接触部１８，９Ｃの離間距離を検査する場合に、接続部５の内部空間を通過する光線を用いることができる。 Further, when the female terminal fitting 1 is bent, the locking edge 25 protruding from the base end portion 9 </ b> A fits into the locking hole 26 provided in the side wall portion 15, thereby elastic contact. The proximal end portion 9A of the piece 9 is positioned. For this reason, for example, compared with the case where a locking part having a configuration in which a part of the side wall part 15 is cut and raised and the inner part thereof is folded on the upper surface of the base end part 9A is provided, the labor of processing can be reduced.
Moreover, since the connection part 5 is made into the cylinder shape open | released in the front-back both directions, when test | inspecting the separation distance of both the contact parts 18 and 9C in the female terminal metal fitting 1, it passes through the internal space of the connection part 5. Can be used.
