Abstract

PROBLEM TO BE SOLVED: To provide a female terminal having high connection reliability that can be surely conductively connected to a male terminal with avoiding large-size design and a method of molding the female terminal.SOLUTION: A male terminal guide portion 51 is formed at the front end of a box portion 12 which is provided with an insertion port 36 at one surface of the box portion 12 where the base end 45a of a contact point spring 45 is located, and has a guide face 52 for guiding into the box portion 12 a tab piece 16 of a male terminal 15 to be inserted from the insertion port 36 into the box portion 12. When the tab piece 16 of the male terminal 15 is inserted into the box portion 12, the contact point 46 is brought into contact with the tab piece 16 of the male terminals 15, and the contact point spring 45 which displaces outwards is released from the lock of the male terminal guide 51.

Description

本発明は、雄端子が挿入されることで雄端子と導通接続される雌端子及びその成形方法に関する。   The present invention relates to a female terminal that is electrically connected to a male terminal by inserting the male terminal, and a molding method thereof.

雄端子が挿入されることにより、雄端子と電気的に導通する雌端子には、雄端子が挿入される箱部内に接点バネを設けたものがある。   Some of the female terminals that are electrically connected to the male terminal by inserting the male terminal include a contact spring provided in a box portion in which the male terminal is inserted.

このような雌端子として、接点バネに段差状の拾い部を形成するとともに、拾い部の進入可能部が進入可能な逃がし窓を箱部に設け、接点バネが必要以上に変形してしまうことを規制して導通不良の発生を低減するものがある（例えば、特許文献１参照）。   As such a female terminal, a step-shaped pick-up part is formed in the contact spring, and a relief window into which the enterable part of the pick-up part can enter is provided in the box part, and the contact spring is deformed more than necessary. There is one that regulates and reduces the occurrence of poor conduction (for example, see Patent Document 1).

また、接点バネを突起部で押し下げておくことで、押し下げた分だけ予めバネ接点部を弾性的に変位させておき、雄端子の挿入前の状態で雄端子の収容空間に向けて予め荷重を生じさせ、挿入された雄端子への接点バネの接触力を高める雌端子がある（例えば、特許文献２参照）。   In addition, by pressing down the contact spring at the protrusion, the spring contact portion is elastically displaced in advance by the amount of the push down, and a load is applied in advance toward the male terminal housing space before the male terminal is inserted. There is a female terminal that is generated and increases the contact force of the contact spring to the inserted male terminal (see, for example, Patent Document 2).

さらに、接点バネとともに、補助バネを設け、雄端子が挿入された際に、接点バネの反力と補助バネの反力の和が接触荷重となるようにした雌端子も知られている（例えば、特許文献３参照）。   Furthermore, a female terminal is also known in which an auxiliary spring is provided together with the contact spring so that the sum of the reaction force of the contact spring and the reaction force of the auxiliary spring becomes a contact load when the male terminal is inserted (for example, And Patent Document 3).

特開２０１２−１０４４３１号公報JP 2012-104431 A 特開２００５−１６６５９４号公報JP 2005-166594 A 特開２００７−３５６２９号公報JP 2007-35629 A

ところで、雄端子を雌端子の箱部内に挿し込む際に、例えば、雄端子が傾いた状態などの不適正な姿勢で挿入される場合がある。すると、進入する雄端子によって雌端子がこじられ、雄端子への接点の接圧が低下し、導通不良を起こすおそれがある。   By the way, when inserting the male terminal into the box portion of the female terminal, the male terminal may be inserted in an inappropriate posture such as a state where the male terminal is inclined. Then, the female terminal is twisted by the entering male terminal, and the contact pressure of the contact with the male terminal is lowered, which may cause poor conduction.

また、雄端子への接点の接圧を高めるためにバネを複数にすると、雌端子の大型化を招いてしまう。   Further, if a plurality of springs are used to increase the contact pressure of the contact to the male terminal, the female terminal will be increased in size.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、大型化を回避しつつ、導通不良なく雄端子と確実に導通接続することが可能な接続信頼性の高い雌端子及びその成形方法を提供することにある。   The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a female terminal with high connection reliability capable of reliably conducting a connection with a male terminal without poor conduction while avoiding an increase in size. The object is to provide a molding method.

前述した目的を達成するために、本発明に係る雌端子は、下記（１）〜（３）を特徴としている。
（１） タブ状の雄端子が挿入されることで該雄端子と導通接続される雌端子であって、
前記雄端子が挿入される挿入口を有する中空筒状の箱部と、
前記箱部から該箱部の内方に向かって延設され、かつ前記箱部の内方側へ突出した接点を有する接点バネと、
前記箱部の外方へ向かって変位した状態の前記接点バネの自由端を係止する雄端子ガイド部と、
を備え、
前記雄端子ガイド部は、前記接点バネの基端が位置する前記箱部の一面における前記挿入口が設けられた前記箱部の前端に形成されているとともに、前記挿入口から前記箱部内へ挿入される前記雄端子を前記箱部内へ導くガイド面を有し、
前記雄端子が前記箱部に挿入された際に、前記雄端子に前記接点が接触してさらに前記箱部の外方へ向かって変位した前記接点バネは、前記雄端子ガイド部による係止が解除されること。
（２） 上記（１）の構成の雌端子において、前記雄端子ガイド部は、前記箱部に挿入された前記雄端子に接触可能な補助接点を有すること。
（３） 上記（１）または（２）の構成の雌端子において、前記接点バネは、前記接点よりも基端側で前記箱部の内方側へ突出し、前記箱部に挿入された前記雄端子に接触可能な補助接点を有すること。 In order to achieve the above-described object, the female terminal according to the present invention is characterized by the following (1) to (3).
(1) A female terminal electrically connected to the male terminal by inserting a tab-shaped male terminal,
A hollow cylindrical box having an insertion port into which the male terminal is inserted;
A contact spring having a contact point extending from the box part toward the inside of the box part and protruding inward of the box part;
A male terminal guide portion for locking the free end of the contact spring in a state displaced toward the outside of the box portion;
With
The male terminal guide part is formed at a front end of the box part provided with the insertion port on one surface of the box part where a base end of the contact spring is located, and is inserted into the box part from the insertion port. A guide surface for guiding the male terminal into the box,
When the male terminal is inserted into the box part, the contact spring that is displaced toward the outside of the box part by the contact of the contact with the male terminal is locked by the male terminal guide part. To be released.
(2) In the female terminal configured as described in (1) above, the male terminal guide portion has an auxiliary contact that can contact the male terminal inserted into the box portion.
(3) In the female terminal having the configuration of (1) or (2), the contact spring protrudes inward of the box part at a proximal end side with respect to the contact, and is inserted into the box part. Have auxiliary contacts that can contact the terminals.

上記（１）の構成の雌端子では、箱部の挿入口から雄端子が近接されると、雄端子の先端部が雄端子ガイド部のガイド面に接触して摺動することで、雄端子が箱部内に導かれる。したがって、挿入口から箱部内に挿入される雄端子の姿勢が斜めであったり、挿入口に対して挿入方向と交差する方向にずれていても、雄端子を箱部内へ円滑に案内することができる。
さらに雄端子が箱部内に挿し込まれることで、雄端子には、予め箱部の外方へ向かって変位されて予備荷重が付与されていた接点バネの接点が接触して弾性変形する。したがって、接点バネの接点は、変位荷重に予備荷重を加えた大きな荷重で雄端子に接することとなり、よって、複数のバネを設けた構造と比較して、大型化を回避しつつ雌端子と雄端子とを高い信頼性で導通接続させることができる。
また、箱部への挿入直後に接点バネが大きな荷重で雄端子に接触することで、雄端子の姿勢を適正な位置へ容易に修正することができ、さらに接続信頼性を高めることができる。
上記（２）の構成の雌端子では、挿入口の近傍に設けた雄端子ガイド部に補助接点を設けたので、ガイド面とともに補助接点によって、挿入される雄端子の傾きを挿入口の近傍で確実に修正することができ、他の接点の偏摩耗を抑制することができる。また、雄端子が僅かに傾いた状態で箱部内に収容されても、挿入口の近傍に配置された補助接点が雄端子に接触するので、挿入後も雄端子の傾きを修正することができるとともに複数の接点で安定的な接触を確保することができる。
上記（３）の構成の雌端子では、雄端子が僅かに傾いた状態で箱部内に収容されても、雄端子に接点バネの補助接点が接触するので、挿入後も雄端子の傾きを修正することができるとともに複数の接点で安定的な接触を確保することができる。 In the female terminal configured as described in (1) above, when the male terminal is brought close to the insertion opening of the box portion, the distal end portion of the male terminal comes into contact with the guide surface of the male terminal guide portion and slides. Is led into the box. Therefore, the male terminal can be smoothly guided into the box even when the posture of the male terminal inserted into the box from the insertion slot is oblique or is shifted in the direction intersecting the insertion direction with respect to the insertion slot. it can.
Further, the male terminal is inserted into the box portion, so that the contact of the contact spring that has been preliminarily displaced toward the outer side of the box portion and applied with the preliminary load comes into contact with the male terminal and is elastically deformed. Therefore, the contact of the contact spring comes into contact with the male terminal with a large load obtained by adding a preload to the displacement load. Therefore, compared with a structure in which a plurality of springs are provided, the female terminal and the male terminal are avoided while being enlarged. The terminal can be conductively connected with high reliability.
Further, since the contact spring contacts the male terminal with a large load immediately after insertion into the box portion, the posture of the male terminal can be easily corrected to an appropriate position, and connection reliability can be further improved.
In the female terminal configured as described above (2), since the auxiliary contact is provided in the male terminal guide portion provided in the vicinity of the insertion opening, the inclination of the inserted male terminal is adjusted in the vicinity of the insertion opening by the auxiliary contact together with the guide surface. It can correct reliably and can suppress the uneven wear of other contacts. Further, even if the male terminal is housed in the box part in a slightly inclined state, the auxiliary contact disposed in the vicinity of the insertion port contacts the male terminal, so that the inclination of the male terminal can be corrected even after insertion. At the same time, stable contact can be ensured with a plurality of contacts.
In the female terminal having the configuration of (3) above, the auxiliary contact of the contact spring contacts the male terminal even if it is housed in the box with the male terminal slightly tilted, so the inclination of the male terminal is corrected even after insertion. It is possible to ensure stable contact with a plurality of contacts.

また、上述した目的を達成するために、本発明に係る雌端子の成形方法は、下記（４）を特徴としている。
（４） タブ状の雄端子が挿入されることで該雄端子と導通接続される雌端子の成形方法であって、
平板を型抜きして折り曲げることで、前記雄端子が挿入される挿入口を有する中空筒状の箱部と、前記箱部から該箱部の内方に向かって延設され、かつ前記箱部の内方側へ突出した接点を有する接点バネと、前記接点バネの基端が位置する前記箱部の一面における前記挿入口が設けられた前記箱部の前端に設けられる雄端子ガイド部と、を形成する箱部形成ステップと、
前記雄端子ガイド部を折り曲げることで、前記雄端子ガイド部で前記接点バネの先端を係止させ前記箱部の外方へ向かって前記接点バネを変位させるとともに、前記雄端子ガイド部に、前記挿入口から前記箱部内へ挿入される前記雄端子を前記箱部内へ導くガイド面を形成するガイド部形成ステップとを有すること。 In order to achieve the above-described object, the female terminal molding method according to the present invention is characterized by the following (4).

図１に示すように、本実施形態に係る雌端子１１は、中空の角筒状に形成された箱部１２と、この箱部１２の後端から延出した電線加締め部１３とを備えている。この雌端子１１は、銅などの導電性を有する金属板をプレス加工することで成形される。   As shown in FIG. 1, the female terminal 11 according to the present embodiment includes a box portion 12 formed in a hollow rectangular tube shape, and a wire crimping portion 13 extending from the rear end of the box portion 12. ing. The female terminal 11 is formed by pressing a conductive metal plate such as copper.

箱部１２には、その先端側から雄端子１５のタブ片１６が挿入される。これにより、雌端子１１に雄端子１５が接続され、これらの雌端子１１と雄端子１５とが導通される。雌端子１１の箱部１２には、その一側部に、上方へ突出する挿入案内用突片１４が形成されている。この挿入案内用突片１４は、箱部１２の側壁の一部を上方へ延長したもので、コネクタハウジング（図示略）へ挿入して収容する際のガイドとなる。   A tab piece 16 of a male terminal 15 is inserted into the box portion 12 from the tip side. Thereby, the male terminal 15 is connected to the female terminal 11, and the female terminal 11 and the male terminal 15 are electrically connected. The box portion 12 of the female terminal 11 is formed with an insertion guide protrusion 14 protruding upward on one side thereof. This insertion guide protrusion 14 is an extension of a part of the side wall of the box portion 12 and serves as a guide for insertion into a connector housing (not shown).

電線加締め部１３は、電線（図示略）の導体を圧着する導体加締め片１３ａと、電線の被覆部に加締め付けることで電線を固定する被覆加締め片１３ｂとを備える。   The electric wire crimping portion 13 includes a conductor crimping piece 13a for crimping a conductor of an electric wire (not shown) and a covering crimping piece 13b for fixing the electric wire by crimping the electric wire covering portion.

図２に示すように、雌端子１１の箱部１２は、底部を構成するベース壁部３２と、このベース壁部３２の幅方向の両側縁部から垂直に立ち上がる一対の側壁部３３と、これらの側壁部３３におけるベース壁部３２と反対側の縁部同士にわたって設けられた上壁部３４とを有する正面視矩形状に形成されている。この箱部１２は、その内部がタブ収容空間３５とされており、電線加締め部１３と反対側の前端側が、雄端子１５のタブ片１６が挿抜される挿入口３６とされている。   As shown in FIG. 2, the box portion 12 of the female terminal 11 includes a base wall portion 32 constituting a bottom portion, a pair of side wall portions 33 rising vertically from both side edges in the width direction of the base wall portion 32, and these The side wall 33 is formed in a rectangular shape in a front view having a base wall 32 and an upper wall 34 provided over the opposite edges. The inside of the box portion 12 is a tab accommodating space 35, and the front end side opposite to the wire crimping portion 13 is an insertion port 36 into which the tab piece 16 of the male terminal 15 is inserted and removed.

箱部１２には、ベース壁部３２に、二つの接点４１，４２が形成されている。これらの接点４１，４２は、ベース壁部３２を箱部１２の内方側へ突出させることで形成されており、タブ片１６の挿入方向に沿って間隔をあけて配列されている。タブ片１６の挿入方向前方側に配置された接点４２は、挿入方向に沿う接触面４２ａを有している。   Two contact points 41 and 42 are formed on the base wall portion 32 of the box portion 12. These contact points 41 and 42 are formed by projecting the base wall portion 32 inward of the box portion 12, and are arranged at intervals along the insertion direction of the tab pieces 16. The contact 42 arranged on the front side of the tab piece 16 in the insertion direction has a contact surface 42a along the insertion direction.

箱部１２には、タブ収容空間３５内における上壁部３４の近傍に、接点バネ４５が設けられている。この接点バネ４５は、タブ片１６の挿入方向前方側の基端４５ａが、箱部１２におけるタブ片１６の挿入方向前方側である後端側の近傍で、側壁部３３に連結されている。そして、この接点バネ４５は、その自由端４５ｂが、箱部１２の内方へ向かいつつ挿入口３６へ延在されている。この接点バネ４５は、自由端４５ｂの近傍部分に、箱部１２の内方側へ突出する接点４６を有している。   The box portion 12 is provided with a contact spring 45 in the vicinity of the upper wall portion 34 in the tab accommodating space 35. The contact spring 45 is connected to the side wall portion 33 in the vicinity of the rear end side, which is the front side in the insertion direction of the tab piece 16 in the box portion 12, in the proximal end 45 a of the tab piece 16 in the insertion direction. The contact spring 45 has a free end 45b extending to the insertion port 36 while facing inward of the box portion 12. The contact spring 45 has a contact 46 projecting inward of the box portion 12 in the vicinity of the free end 45b.

また、箱部１２には、挿入口３６に、雄端子ガイド部５１が設けられている。この雄端子ガイド部５１は、上壁部３４の先端側をタブ収容空間３５内へ折り返すことで形成されている。この雄端子ガイド部５１は、タブ片１６の挿入方向前方へ向かって次第に箱部１２の内方へ傾斜するテーパ形状のガイド面５２を有している。また、この雄端子ガイド部５１は、その端部が、接点バネ４５の自由端４５ｂを係止する係止部５３とされており、この係止部５３は、接点バネ４５の自由端４５ｂよりも箱部１２の内方側に配置されている。   The box portion 12 is provided with a male terminal guide portion 51 at the insertion port 36. The male terminal guide portion 51 is formed by folding the tip end side of the upper wall portion 34 into the tab accommodating space 35. The male terminal guide portion 51 has a tapered guide surface 52 that is gradually inclined inward of the box portion 12 toward the front in the insertion direction of the tab piece 16. Further, the male terminal guide portion 51 has an end portion serving as a locking portion 53 that locks the free end 45 b of the contact spring 45, and the locking portion 53 is connected to the free end 45 b of the contact spring 45. Is also arranged on the inner side of the box portion 12.

ここで、接点バネ４５は、箱部１２の内方へ向かって予備荷重が付与されている。そして、この接点バネ４５は、予備荷重が付与された状態で、その自由端４５ｂが雄端子ガイド部５１の係止部５３で係止され、箱部１２の内方側への移動が規制されている。   Here, the contact spring 45 is given a preload toward the inside of the box portion 12. The contact spring 45 is locked at its free end 45b by the locking portion 53 of the male terminal guide portion 51 in a state where a preliminary load is applied, and the movement of the box portion 12 to the inward side is restricted. ing.

上記構造の雌端子１１に雄端子１５を接続する場合について説明する。   A case where the male terminal 15 is connected to the female terminal 11 having the above structure will be described.

雌端子１１の箱部１２の挿入口３６から雄端子１５のタブ片１６が近接されると、タブ片１６の先端部が雄端子ガイド部５１のガイド面５２に接触して摺動することで、タブ片１６は、タブ収容空間３５における接点４１，４２側へ案内され、接点４１と雄端子ガイド部５１との間に導かれる。したがって、挿入口３６から箱部１２のタブ収容空間３５内へ挿入される雄端子１５のタブ片１６の姿勢が斜めであったり、挿入口３６に対して挿入方向と交差する方向にずれていても、雄端子１５のタブ片１６は、雄端子ガイド部５１のガイド面５２によってタブ収容空間３５へ円滑に案内される。   When the tab piece 16 of the male terminal 15 comes close to the insertion port 36 of the box portion 12 of the female terminal 11, the tip of the tab piece 16 comes into contact with the guide surface 52 of the male terminal guide portion 51 and slides. The tab piece 16 is guided to the contact points 41 and 42 side in the tab accommodating space 35 and is guided between the contact point 41 and the male terminal guide part 51. Accordingly, the posture of the tab piece 16 of the male terminal 15 inserted into the tab accommodating space 35 of the box portion 12 from the insertion port 36 is oblique or shifted in a direction intersecting the insertion direction with respect to the insertion port 36. In addition, the tab piece 16 of the male terminal 15 is smoothly guided to the tab accommodating space 35 by the guide surface 52 of the male terminal guide portion 51.

この状態で、さらにタブ片１６が箱部１２内に挿し込まれると、タブ片１６に接点４１及び接点バネ４５の接点４６が接触する。   When the tab piece 16 is further inserted into the box portion 12 in this state, the contact 41 and the contact 46 of the contact spring 45 come into contact with the tab piece 16.

さらにタブ片１６が箱部１２内に挿し込まれると、図３に示すように、タブ片１６によって接点バネ４５が押し上げられ、雄端子ガイド部５１の係止部５３による係止が解除されて接点バネ４５が弾性変形するとともに、タブ片１６に接点４２の接触面４２ａが接触した接続状態となる。   When the tab piece 16 is further inserted into the box portion 12, the contact spring 45 is pushed up by the tab piece 16 and the locking by the locking portion 53 of the male terminal guide portion 51 is released as shown in FIG. The contact spring 45 is elastically deformed, and the contact state 42 a of the contact 42 contacts the tab piece 16.

この接続状態において、タブ片１６には、接点４１，４２と、これらの接点４１，４２の対向側の接点バネ４５の接点４６とが挿入方向の異なる位置で接触することとなる。また、接点バネ４５は、予備荷重が付与されているため、タブ片１６によって弾性変形することで、その変位荷重に予備荷重を加えた大きな荷重で接点４６がタブ片１６に接することとなる。   In this connected state, the tab pieces 16 are brought into contact with the contacts 41 and 42 and the contact 46 of the contact spring 45 on the opposite side of the contacts 41 and 42 at different positions in the insertion direction. Further, since the contact spring 45 is given a preliminary load, it is elastically deformed by the tab piece 16 so that the contact 46 contacts the tab piece 16 with a large load obtained by adding the preliminary load to the displacement load.

これにより、タブ片１６は、接点４１，４２と接点４６とで安定的かつ大きな荷重で挟持され、よって、雌端子１１と雄端子１５とが高い信頼性で導通接続される。   As a result, the tab piece 16 is sandwiched between the contacts 41 and 42 and the contact 46 with a stable and large load, so that the female terminal 11 and the male terminal 15 are conductively connected with high reliability.

このように、上記の雌端子１１によれば、箱部１２の挿入口３６から雄端子１５のタブ片１６が近接されると、雄端子１５のタブ片１６の先端部が雄端子ガイド部５１のガイド面５２に接触して摺動することで、雄端子１５のタブ片１６が箱部１２内に導かれる。したがって、挿入口３６から箱部１２内に挿入される雄端子１５のタブ片１６の姿勢が斜めであったり、挿入口３６に対して挿入方向と交差する方向にずれていても、雄端子１５のタブ片１６を箱部１２内へ円滑に案内することができる。   As described above, according to the female terminal 11 described above, when the tab piece 16 of the male terminal 15 is brought close to the insertion port 36 of the box portion 12, the distal end portion of the tab piece 16 of the male terminal 15 becomes the male terminal guide portion 51. The tab piece 16 of the male terminal 15 is guided into the box 12 by sliding in contact with the guide surface 52. Therefore, even if the posture of the tab piece 16 of the male terminal 15 inserted into the box portion 12 from the insertion port 36 is oblique or is shifted in a direction intersecting the insertion direction with respect to the insertion port 36, the male terminal 15 The tab pieces 16 can be smoothly guided into the box portion 12.

さらに雄端子１５のタブ片１６が箱部１２内に挿し込まれることで、雄端子１５のタブ片１６には、予め箱部１２の外方へ向かって変位されて予備荷重が付与されていた接点バネ４５の接点４６が接触して弾性変形する。したがって、接点バネ４５の接点４６は、変位荷重に予備荷重を加えた大きな荷重で雄端子１５のタブ片１６に接することとなり、よって、複数のバネを設けた構造と比較して、大型化を回避しつつ雌端子１１と雄端子１５とを高い信頼性で導通接続させることができる。   Further, the tab piece 16 of the male terminal 15 is inserted into the box portion 12, so that the tab piece 16 of the male terminal 15 is preliminarily displaced toward the outside of the box portion 12 and given a preliminary load. The contact 46 of the contact spring 45 comes into contact and elastically deforms. Therefore, the contact 46 of the contact spring 45 comes into contact with the tab piece 16 of the male terminal 15 with a large load obtained by adding a preliminary load to the displacement load. Therefore, the contact spring 45 is increased in size as compared with the structure provided with a plurality of springs. The female terminal 11 and the male terminal 15 can be conductively connected with high reliability while being avoided.

また、箱部１２への挿入直後に接点バネ４５が大きな荷重で雄端子１５のタブ片１６に接触することで、雄端子１５のタブ片１６の姿勢を適正な位置へ容易に修正することができ、さらに接続信頼性を高めることができる。   Further, the contact spring 45 is brought into contact with the tab piece 16 of the male terminal 15 with a large load immediately after being inserted into the box portion 12, so that the posture of the tab piece 16 of the male terminal 15 can be easily corrected to an appropriate position. Connection reliability can be further improved.

次に、導電性金属板を加工して雌端子１１を成形する場合について説明する。   Next, a case where the female terminal 11 is formed by processing a conductive metal plate will be described.

図４は、雌端子の成形方法を示す図であって、図４（ａ）〜図４（ｅ）は、それぞれ成形途中における雌端子の箱部の斜視図、図５は、成形途中における雌端子の箱部の断面図、図６は、成形途中における雌端子の箱部の断面図、図７は、成形途中における雌端子の箱部の断面図である。   4A and 4B are diagrams showing a method of forming a female terminal, in which FIGS. 4A to 4E are perspective views of a box portion of the female terminal in the middle of molding, and FIG. 5 is a female in the middle of molding. FIG. 6 is a sectional view of the box portion of the female terminal during molding, and FIG. 7 is a sectional view of the box portion of the female terminal during molding.

（箱部形成ステップ）
図４（ａ）に示すように、導電性金属板１０１をプレス加工することで、組み立てたときに雌端子１１の形状となる所定の形状に打ち抜く。これにより、導電性金属板１０１に、箱部１２を構成するベース壁部３２、側壁部３３、上壁部３４、接点バネ４５及び雄端子ガイド部５１となる部分を形成し、ベース壁部３２に接点４１，４２を形成する。 (Box formation step)
As shown in FIG. 4A, by pressing the conductive metal plate 101, it is punched into a predetermined shape that becomes the shape of the female terminal 11 when assembled. As a result, the base wall portion 32, the side wall portion 33, the upper wall portion 34, the contact spring 45, and the male terminal guide portion 51 constituting the box portion 12 are formed on the conductive metal plate 101. The contacts 41 and 42 are formed on the substrate.

図４（ｂ）に示すように、接点バネ４５と側壁部３３との境界部分を、接点バネ４５の後端部の基端４５ａで屈曲させ、側壁部３３に対して接点バネ４５を直角に立ち上げる。   4B, the boundary portion between the contact spring 45 and the side wall portion 33 is bent at the base end 45a of the rear end portion of the contact spring 45 so that the contact spring 45 is perpendicular to the side wall portion 33. Launch.

図４（ｃ）に示すように、側壁部３３とベース壁部３２との境界部分を屈曲させ、ベース壁部３２に対して側壁部３３を直角に立ち上げる。このようにすると、接点バネ４５が側壁部３３の間に配置される。また、接点バネ４５の基端４５ａにおける一方の側壁部３３との連結側と反対側に形成した係止突起４５ｃが、他方の側壁部３３に形成された係止孔３３ａに入り込み、よって、接点バネ４５の後端からなる基端４５ａが両方の側壁部３３に支持された状態となる。   As shown in FIG. 4C, the boundary portion between the side wall portion 33 and the base wall portion 32 is bent, and the side wall portion 33 is raised at a right angle with respect to the base wall portion 32. In this way, the contact spring 45 is disposed between the side wall portions 33. In addition, a locking projection 45c formed on the side of the base end 45a of the contact spring 45 opposite to the connection side with the one side wall portion 33 enters the locking hole 33a formed on the other side wall portion 33. The base end 45 a, which is the rear end of the spring 45, is in a state supported by both side wall portions 33.

図４（ｄ）に示すように、上壁部３４と側壁部３３との境界部分を屈曲させ、上壁部３４を水平に配置させる。これにより、接点バネ４５の上部側が上壁部３４に覆われた箱部１２が形成される。   As shown in FIG. 4D, the boundary portion between the upper wall portion 34 and the side wall portion 33 is bent, and the upper wall portion 34 is disposed horizontally. Thereby, the box part 12 in which the upper side of the contact spring 45 is covered with the upper wall part 34 is formed.

図４（ｅ）に示すように、雄端子ガイド部５１をタブ収容空間３５側へ折り曲げる。この後、側壁部３３におけるタブ片１６の挿入方向後側に位置し、上方へ突出する突片を、挿入口３６側へ折り曲げる。   As shown in FIG. 4E, the male terminal guide 51 is bent toward the tab accommodating space 35 side. Thereafter, the protruding piece located on the rear side in the insertion direction of the tab piece 16 in the side wall portion 33 and protruding upward is bent toward the insertion port 36 side.

上記の加工により、箱部１２では、図５に示すように、接点バネ４５が箱部１２内の中央付近に配置され、接点４６は、接点４１，４２に対して隙間Ｇをあけた位置に配置される。また、この状態では、雄端子ガイド部５１の先端部からなる係止部５３が接点バネ４５の自由端４５ｂから離間している。   As a result of the above processing, in the box portion 12, as shown in FIG. 5, the contact spring 45 is arranged near the center in the box portion 12, and the contact 46 is located at a position where a gap G is opened with respect to the contacts 41 and 42. Be placed. In this state, the locking portion 53 formed of the tip of the male terminal guide portion 51 is separated from the free end 45 b of the contact spring 45.

（ガイド部形成ステップ）
図６に示すように、箱部１２の先端側である挿入口３６側から、雄端子ガイド部５１を成形するガイド部成形凹部１０２を有する治具１０３を、雄端子ガイド部５１へ向かって（図６中矢印Ａ方向）近接させる。 (Guide part forming step)
As shown in FIG. 6, a jig 103 having a guide portion forming recess 102 for forming the male terminal guide portion 51 is directed from the insertion port 36 side, which is the distal end side of the box portion 12, toward the male terminal guide portion 51 ( In the direction of arrow A in FIG.

図７に示すように、治具１０３を挿入口３６側から近接させることで、治具１０３のガイド部成形凹部１０２に雄端子ガイド部５１を圧入させる。   As shown in FIG. 7, the male terminal guide portion 51 is press-fitted into the guide portion forming concave portion 102 of the jig 103 by bringing the jig 103 close from the insertion port 36 side.

すると、雄端子ガイド部５１は、ガイド部成形凹部１０２の内面に沿って屈曲されることで、タブ収容空間３５内へさらに折り返される。これにより、雄端子ガイド部５１に、ガイド面５２が形成されるとともに、雄端子ガイド部５１の係止部５３が接点バネ４５の自由端４５ｂの下方に入り込んで上方へ持ち上げることとなる。したがって、接点バネ４５は、その自由端４５ｂが雄端子ガイド部５１によって係止されるとともに、上方へ持ち上げられるように弾性変形された状態となり、接点４６は、接点４１，４２に対して、隙間Ｇよりも広い隙間Ｇ０をあけた位置に配置される。   Then, the male terminal guide portion 51 is further folded back into the tab accommodating space 35 by being bent along the inner surface of the guide portion forming recess 102. As a result, a guide surface 52 is formed on the male terminal guide portion 51, and the locking portion 53 of the male terminal guide portion 51 enters below the free end 45b of the contact spring 45 and lifts upward. Therefore, the contact spring 45 is in a state in which its free end 45b is locked by the male terminal guide portion 51 and is elastically deformed so as to be lifted upward. It is arranged at a position with a gap G0 wider than G.

これにより、接点バネ４５が予め箱部１２の外方へ向かって弾性変形されて箱部１２の内方へ向かって予備荷重が付与された雌端子１１が得られる。   As a result, the contact spring 45 is elastically deformed toward the outside of the box portion 12 in advance, and the female terminal 11 to which a preliminary load is applied toward the inside of the box portion 12 is obtained.

このように、上記の箱部形成ステップと、ガイド部形成ステップとによって、導通不良を起こすことなく、雄端子１５と確実に導通接続することが可能な接続信頼性の高い雌端子１１を容易に得ることができる。   As described above, the box part forming step and the guide part forming step make it easy to connect the female terminal 11 with high connection reliability that can be securely connected to the male terminal 15 without causing poor conduction. Can be obtained.

（第２実施形態）
次に、第２実施形態に係る雌端子について説明する。

Sectional drawing of a box part, FIG. 10 is sectional drawing of the box part of the female terminal which shows the connection state of the male terminal to the female terminal which concerns on 2nd Embodiment.

図８に示すように、第２実施形態に係る雌端子１１Ａでは、雄端子ガイド部５１が箱部１２の内方側へ突出するように湾曲され、この湾曲部分が補助接点５４とされている。この補助接点５４は、タブ片１６の挿入前において、接点バネ４５の接点４６よりも箱部１２の外方側に配置されている。   As shown in FIG. 8, in the female terminal 11 </ b> A according to the second embodiment, the male terminal guide portion 51 is curved so as to protrude inward of the box portion 12, and this curved portion is used as the auxiliary contact 54. . The auxiliary contact 54 is disposed on the outer side of the box portion 12 with respect to the contact 46 of the contact spring 45 before the tab piece 16 is inserted.

また、この雌端子１１Ａでは、タブ片１６の挿入方向に沿う接触面４２ａのない接点４２を備えている。   Further, the female terminal 11 </ b> A includes a contact 42 having no contact surface 42 a along the insertion direction of the tab piece 16.

上記構造の雌端子１１Ａに雄端子１５を接続する場合について説明する。   A case where the male terminal 15 is connected to the female terminal 11A having the above structure will be described.

雌端子１１Ａの箱部１２の挿入口３６から雄端子１５のタブ片１６が近接されると、タブ片１６の先端部が雄端子ガイド部５１のガイド面５２に接触して摺動することで、タブ片１６は、タブ収容空間３５における接点４１，４２側へ案内され、接点４１と雄端子ガイド部５１との間に導かれる。したがって、挿入口３６に挿入される雄端子１５のタブ片１６の姿勢が斜めであったり、挿入口３６に対して挿入方向と交差する方向にずれていても、雄端子１５のタブ片１６は、雄端子ガイド部５１のガイド面５２によって箱部１２内へ円滑に案内される。   When the tab piece 16 of the male terminal 15 comes close to the insertion port 36 of the box portion 12 of the female terminal 11A, the tip of the tab piece 16 comes into contact with the guide surface 52 of the male terminal guide portion 51 and slides. The tab piece 16 is guided to the contact points 41 and 42 side in the tab accommodating space 35 and is guided between the contact point 41 and the male terminal guide part 51. Therefore, even if the posture of the tab piece 16 of the male terminal 15 inserted into the insertion port 36 is oblique or is shifted in the direction intersecting the insertion direction with respect to the insertion port 36, the tab piece 16 of the male terminal 15 is The guide surface 52 of the male terminal guide portion 51 is smoothly guided into the box portion 12.

この状態で、さらにタブ片１６が箱部１２内に挿し込まれると、タブ片１６に接点４１が接触するとともに、接点バネ４５の接点４６も接触する。   When the tab piece 16 is further inserted into the box portion 12 in this state, the contact 41 contacts the tab piece 16 and the contact 46 of the contact spring 45 also contacts.

さらにタブ片１６が箱部１２内に挿し込まれると、図９に示すように、タブ片１６によって接点バネ４５が押し上げられ、雄端子ガイド部５１の係止部５３による係止が解除されて接点バネ４５が弾性変形するとともに、タブ片１６に接点４２が接触した接続状態となる。   When the tab piece 16 is further inserted into the box portion 12, the contact spring 45 is pushed up by the tab piece 16 and the locking by the locking portion 53 of the male terminal guide portion 51 is released as shown in FIG. The contact spring 45 is elastically deformed, and the contact state is brought into contact with the tab piece 16.

この接続状態において、タブ片１６には、接点４１，４２と、これらの接点４１，４２の対向側の接点バネ４５の接点４６とが挿入方向の異なる位置で接触することとなる。また、接点バネ４５は、予備荷重が付与されているため、タブ片１６によって弾性変形することで、その変位荷重に予備荷重を加えた大きな荷重で接点４６がタブ片１６に接することとなる。   In this connected state, the tab pieces 16 are brought into contact with the contacts 41 and 42 and the contact 46 of the contact spring 45 on the opposite side of the contacts 41 and 42 at different positions in the insertion direction. Further, since the contact spring 45 is given a preliminary load, it is elastically deformed by the tab piece 16 so that the contact 46 contacts the tab piece 16 with a large load obtained by adding the preliminary load to the displacement load.

これにより、タブ片１６は、接点４１，４２と、接点４６とで安定的かつ大きな荷重で挟持され、よって、雌端子１１と雄端子１５とが高い信頼性で導通接続される。   As a result, the tab piece 16 is sandwiched between the contacts 41 and 42 and the contact 46 with a stable and large load, so that the female terminal 11 and the male terminal 15 are conductively connected with high reliability.

特に、第２実施形態に係る雌端子１１Ａでは、挿入口３６の近傍に設けた雄端子ガイド部５１に補助接点５４を設けたので、ガイド面５２とともに補助接点５４によって、挿入されるタブ片１６の傾きを挿入口３６の近傍で確実に修正することができ、他の接点４１，４２，４６の偏摩耗を抑制することができる。また、図１０に示すように、雄端子１５のタブ片１６が、僅かに先端が下がるように傾いた状態で箱部１２のタブ収容空間３５内に収容されて接点４１がタブ片１６から離間しても、タブ片１６には、接点４２，４６とともに挿入口３６の近傍に配置された補助接点５４も接触するので、タブ片１６の傾きを修正することができるとともに複数の接点で安定的な接触を確保することができる。   In particular, in the female terminal 11 </ b> A according to the second embodiment, the auxiliary contact 54 is provided in the male terminal guide portion 51 provided in the vicinity of the insertion port 36, so the tab piece 16 inserted by the auxiliary contact 54 together with the guide surface 52. Can be reliably corrected in the vicinity of the insertion port 36, and uneven wear of the other contacts 41, 42, 46 can be suppressed. Further, as shown in FIG. 10, the tab piece 16 of the male terminal 15 is accommodated in the tab accommodating space 35 of the box portion 12 with the tip thereof being slightly inclined so that the contact 41 is separated from the tab piece 16. Even so, the auxiliary contact 54 disposed in the vicinity of the insertion port 36 together with the contacts 42 and 46 contacts the tab piece 16, so that the inclination of the tab piece 16 can be corrected and a plurality of contacts are stable. Contact can be ensured.

FIG. 13 is a cross-sectional view of the box portion of the female terminal showing a connection state of the male terminal to the female terminal according to the second embodiment.

図１１に示すように、第３実施形態に係る雌端子１１Ｂの場合も、雄端子ガイド部５１が箱部１２の内方側へ突出するように湾曲され、この湾曲部分が補助接点５４とされている。この補助接点５４は、タブ片１６の挿入前において、接点バネ４５の接点４６よりも外方側に配置されている。   As shown in FIG. 11, also in the case of the female terminal 11 </ b> B according to the third embodiment, the male terminal guide portion 51 is curved so as to protrude inward of the box portion 12, and this curved portion is used as the auxiliary contact 54. ing. The auxiliary contact 54 is disposed on the outer side of the contact 46 of the contact spring 45 before the tab piece 16 is inserted.

また、この雌端子１１Ｂでは、接点４６とは別に、箱部１２の内方側へ突出する補助接点４７が接点バネ４５に形成されている。これらの接点４６及び補助接点４７は、タブ片１６の挿入方向に沿って間隔をあけて配列されており、補助接点４７は、接点４６よりも箱部１２の外方側に配置されている。   Further, in the female terminal 11 </ b> B, an auxiliary contact 47 that protrudes inward of the box portion 12 is formed on the contact spring 45 separately from the contact 46. The contact 46 and the auxiliary contact 47 are arranged at intervals along the insertion direction of the tab piece 16, and the auxiliary contact 47 is disposed on the outer side of the box portion 12 with respect to the contact 46.

また、この雌端子１１Ｂでは、タブ片１６の挿入方向に沿う接触面４２ａのない接点４２を備えており、接点４６及び補助接点４７は、接点４１，４２におけるタブ片１６の挿入方向の間に配置されている。   Further, the female terminal 11B includes a contact 42 having no contact surface 42a along the insertion direction of the tab piece 16, and the contact 46 and the auxiliary contact 47 are interposed between the insertion directions of the tab piece 16 at the contacts 41 and 42. Has been placed.

上記構造の雌端子１１Ｂに雄端子１５を接続する場合について説明する。   A case where the male terminal 15 is connected to the female terminal 11B having the above structure will be described.

雌端子１１Ｂの箱部１２の挿入口３６から雄端子１５のタブ片１６が近接されると、タブ片１６の先端部が雄端子ガイド部５１のガイド面５２に接触して摺動することで、タブ片１６は、タブ収容空間３５における接点４１，４２側へ案内され、接点４１と雄端子ガイド部５１との間に導かれる。したがって、挿入口３６に挿入される雄端子１５のタブ片１６の姿勢が斜めであったり、挿入口３６に対して挿入方向と交差する方向にずれていても、雄端子１５のタブ片１６は、雄端子ガイド部５１のガイド面５２によって箱部１２内へ円滑に案内される。   When the tab piece 16 of the male terminal 15 comes close to the insertion port 36 of the box part 12 of the female terminal 11B, the tip of the tab piece 16 comes into contact with the guide surface 52 of the male terminal guide part 51 and slides. The tab piece 16 is guided to the contact points 41 and 42 side in the tab accommodating space 35 and is guided between the contact point 41 and the male terminal guide part 51. Therefore, even if the posture of the tab piece 16 of the male terminal 15 inserted into the insertion port 36 is oblique or is shifted in the direction intersecting the insertion direction with respect to the insertion port 36, the tab piece 16 of the male terminal 15 is The guide surface 52 of the male terminal guide portion 51 is smoothly guided into the box portion 12.

この状態で、さらにタブ片１６が箱部１２内に挿し込まれると、タブ片１６に接点４１が接触するとともに、接点バネ４５の接点４６も接触する。   When the tab piece 16 is further inserted into the box portion 12 in this state, the contact 41 contacts the tab piece 16 and the contact 46 of the contact spring 45 also contacts.

さらにタブ片１６が箱部１２内に挿し込まれると、図１２に示すように、タブ片１６によって接点バネ４５が押し上げられ、雄端子ガイド部５１の係止部５３による係止が解除されて接点バネ４５が弾性変形するとともに、タブ片１６に接点４２が接触した接続状態となる。   When the tab piece 16 is further inserted into the box portion 12, the contact spring 45 is pushed up by the tab piece 16 and the locking by the locking portion 53 of the male terminal guide portion 51 is released as shown in FIG. The contact spring 45 is elastically deformed, and the contact state is brought into contact with the tab piece 16.

この接続状態において、タブ片１６には、接点４１，４２と、これらの接点４１，４２の対向側の接点バネ４５の接点４６とが挿入方向の異なる位置で接触することとなる。また、接点バネ４５は、予備荷重が付与されているため、タブ片１６によって弾性変形することで、その変位荷重に予備荷重を加えた大きな荷重で接点４６がタブ片１６に接することとなる。   In this connected state, the tab pieces 16 are brought into contact with the contacts 41 and 42 and the contact 46 of the contact spring 45 on the opposite side of the contacts 41 and 42 at different positions in the insertion direction. Further, since the contact spring 45 is given a preliminary load, it is elastically deformed by the tab piece 16 so that the contact 46 contacts the tab piece 16 with a large load obtained by adding the preliminary load to the displacement load.

これにより、タブ片１６は、接点４１，４２と、接点４６とで安定的にかつ大きな荷重で挟持され、よって、雌端子１１と雄端子１５とが高い信頼性で導通接続される。   As a result, the tab piece 16 is stably sandwiched between the contacts 41 and 42 and the contact 46 with a large load, so that the female terminal 11 and the male terminal 15 are conductively connected with high reliability.

この第３実施形態に係る雌端子１１Ｂの場合も、第２実施形態に係る雌端子１１Ａと同様に、挿入口３６の近傍に設けた雄端子ガイド部５１に補助接点５４を設けたので、ガイド面５２とともに補助接点５４によって、挿入されるタブ片１６の傾きを挿入口３６の近傍で確実に修正することができ、他の接点４１，４２，４６の偏摩耗を抑制することができる。また、雄端子１５のタブ片１６が、僅かに先端が下がるように傾いた状態で箱部１２のタブ収容空間３５内に収容されて接点４１がタブ片１６から離間しても、タブ片１６には、接点４２，４６とともに挿入口３６の近傍に配置された補助接点５４も接触するので、タブ片１６の傾きを修正することができるとともに複数の接点で安定的な接触を確保することができる。   In the case of the female terminal 11B according to the third embodiment, the auxiliary contact 54 is provided in the male terminal guide portion 51 provided in the vicinity of the insertion port 36 in the same manner as the female terminal 11A according to the second embodiment. By the auxiliary contact 54 together with the surface 52, the inclination of the inserted tab piece 16 can be reliably corrected in the vicinity of the insertion port 36, and uneven wear of the other contacts 41, 42, 46 can be suppressed. Further, even if the tab piece 16 of the male terminal 15 is accommodated in the tab accommodating space 35 of the box portion 12 in a state where the tip is slightly lowered, the tab piece 16 is not separated from the tab piece 16. Since the auxiliary contact 54 disposed near the insertion port 36 is also brought into contact with the contacts 42 and 46, the inclination of the tab piece 16 can be corrected and stable contact can be ensured with a plurality of contacts. it can.

また、第３実施形態に係る雌端子１１Ｂでは、図１３に示すように、雄端子１５のタブ片１６が、僅かに先端が上がるように傾いた状態で箱部１２のタブ収容空間３５内に収容されて接点４２がタブ片１６から離間しても、タブ片１６には、接点４１，４６とともに接点バネ４５の補助接点４７も接触するので、タブ片１６の傾きを修正することができるとともに複数の接点で安定的な接触を確保することができる。   Further, in the female terminal 11B according to the third embodiment, as shown in FIG. 13, the tab piece 16 of the male terminal 15 is in the tab accommodating space 35 of the box portion 12 in a state where the tab piece 16 is inclined so that the tip is slightly raised. Even when the contact 42 is accommodated and separated from the tab piece 16, the auxiliary contact 47 of the contact spring 45 contacts the tab piece 16 together with the contacts 41 and 46, so that the inclination of the tab piece 16 can be corrected. Stable contact can be ensured with a plurality of contacts.
