Description

本発明は、例えば携帯電話機に内蔵されてバッテリ接続用として使用される電気コネクタに関する。   The present invention relates to an electrical connector that is built in, for example, a mobile phone and used for battery connection.

携帯電話機には薄型化が要求されている。この要求に対応するために、特許文献１には、バッテリ等の相手接点に接触する接触部がハウジングから前方に突出し、その接触部の後部に弾性的に縮むコイルスプリングを配置した、いわゆるポゴピンコネクタが提案されている。しかしながら、この特許文献１に提案されたポゴピンコネクタは部品点数が多くコスト高である。   Mobile phones are required to be thin. In order to meet this requirement, Patent Document 1 discloses a so-called pogo pin connector in which a contact portion that contacts a mating contact such as a battery protrudes forward from the housing and a coil spring that elastically contracts is arranged at the rear of the contact portion. Has been proposed. However, the pogo pin connector proposed in Patent Document 1 has a large number of parts and is expensive.

特許文献２には、板金の打抜きおよび折曲げ加工により、上記のコイルスプリングの役割りを担うばね部を含むコンタクトが一体に形成された、部品点数の少ない電気コネクタが提案されている。   Patent Document 2 proposes an electrical connector having a small number of parts, in which contacts including a spring portion serving as the coil spring are integrally formed by punching and bending a sheet metal.

特開２０１１−９６６０６号公報JP 2011-96606 A 特開平１１−１６２５９２号公報Japanese Patent Laid-Open No. 11-162592

しかしながら、特許文献２に提案された電気コネクタは、接触部の十分な変位量を確保するためにはコンタクトの高さや前後方向の長さを大きくする必要がある。このため電気コネクタの小型化が困難である。また、この特許文献２の電気コネクタは、そのコンタクトのばね部の、打抜き加工により形成された打抜き面がハウジングの内壁面に対面している。このばね部は、相手接点が接触部を押すたびに変形するため、ばね部の打抜き面でハウジングが削れるおそれがあり、電気コネクタの耐久性にも問題が残る。   However, in the electrical connector proposed in Patent Document 2, it is necessary to increase the height of the contact and the length in the front-rear direction in order to ensure a sufficient amount of displacement of the contact portion. For this reason, it is difficult to reduce the size of the electrical connector. In the electrical connector disclosed in Patent Document 2, the punched surface formed by punching of the spring portion of the contact faces the inner wall surface of the housing. Since the spring portion is deformed each time the counterpart contact presses the contact portion, the housing may be scraped off by the punched surface of the spring portion, and there remains a problem in the durability of the electrical connector.

本発明は、上記事情に鑑み、小型化かつ耐久性の向上が図られた電気コネクタを提供することを目的とする。   In view of the above circumstances, an object of the present invention is to provide an electrical connector that is reduced in size and improved in durability.

上記目的を達成する本発明の電気コネクタは、
前方に突出し相手接点に接触して相手接点からの後方への押圧を受ける接触部と、
その接触部よりも後方に位置し、接触部の、相手接点からの押圧を受けて弾性的に変形するばね部と、そのばね部よりもさらに後方に位置し電気的な接続を担う端子部とを有し、板金の打抜きおよび折曲げ加工を経て一体に形成されたコンタクトと、
上記コンタクトを収容し接触部を前方に突出させたハウジングとを備え、
上記ばね部は、打抜き時点では線材が左右方向に繰り返し折り返しながら前後に延び、線材の左右方向への１回の往復のうちの往路における、左端から、左右方向中央から左右方向それぞれに逸れた２つの点のうちの左寄りの一方の点までの部分が、左右方向にのみ延び、それら２つの点どうしを繋ぐ部分が前後方向に傾いて延び、それら２つの点のうちの右寄りの一方の点から右端までの部分が、左右方向にのみ延び、折り返した復路である右端から左端までの部分が、左右方向にのみ延びた形状を有することで、線材の、打抜き時点における１つの折り返し部分の内側の前後方向の間隔よりも、その線材の、打抜き時点における前後方向に互いに隣接する折り返し部分どうしの前後方向の間隔の方が広い形状に形成され、折曲げ加工を経ることにより、打抜き時点における左右方向の折り返し部分が、該ばね部の他の部分と対面する向き以上に折り曲げられていることを特徴とする。 The electrical connector of the present invention that achieves the above object is as follows.
A contact portion that protrudes forward and contacts the mating contact and receives a backward pressure from the mating contact;
A spring part that is located behind the contact part and elastically deforms upon receiving a pressure from the mating contact of the contact part, and a terminal part that is located further rearward than the spring part and is responsible for electrical connection A contact formed integrally through punching and bending of a sheet metal, and
A housing that accommodates the contact and projects the contact portion forward;
The spring portion extends back and forth while being repeatedly folded back in the left-right direction at the time of punching, and deviates from the left end in the left- right direction to the left-right direction in the forward path of one round-trip of the wire in the left- right direction. The part of the two points up to the left one point extends only in the left-right direction, the part connecting the two points extends obliquely in the front-rear direction, and from the right one of the two points The portion from the right end to the left end that extends only in the left-right direction extends to the right end only, and the portion from the right end to the left end that is the return path extends only in the left-right direction . The space between the folded portions adjacent to each other in the front-rear direction at the time of punching is wider than the space in the front-rear direction. It allows the folded portion of the horizontal direction in the punching point, characterized in that it is bent over the direction facing the other portion of the spring portion.

本発明の電気コネクタにおいて、そのコンタクトが板金の打抜きおよび折曲げ加工を経て一体に形成されている点は、前掲の特許文献２と同じである。ただし、本発明では、そのコンタクトのばね部の、打抜き時点における左右方向の折り返し部分が、ばね部の他の部分と対面する向き以上に折り曲げられている。このため、小型化が達成でき、かつ打抜き面がハウジングの内壁面とは対面しないことから耐久性も向上する。   The electrical connector of the present invention is the same as Patent Document 2 described above in that the contacts are integrally formed through punching and bending of a sheet metal. However, in the present invention, the folded portion in the left-right direction at the time of punching of the spring portion of the contact is bent more than the direction facing the other portion of the spring portion. For this reason, size reduction can be achieved, and durability is also improved because the punched surface does not face the inner wall surface of the housing.

ここで、折り返し部分の内側と外側とを比べたとき、接触部が相手接点に押されたときに、折り返し部分が変形の抵抗となって内側の方が外側よりも変形しにくい。このため、接触部を後方に押し下げていったとき、内側と外側の間隔が互いに同一であると内側の変形には余裕がある段階で、外側の方は線材どうしが接触してしまってそれ以上変形できない状態となる。 Here, when the inner side and the outer side of the folded portion are compared, when the contact portion is pushed by the mating contact, the folded portion becomes a resistance to deformation and the inner side is less likely to be deformed than the outer side. For this reason, when the contact part is pushed backward, if the inner and outer distances are the same, there is a margin for inner deformation, and the outer side is in contact with the wires, and beyond that It cannot be deformed.

そこで、本発明では、線材の左右方向への１回の往復のうちの往路の、線材上の、左右方向中央から左右方向それぞれに逸れた２つの点どうしを繋ぐ部分を、前後方向に傾いて延びた形状に形成することで、内側よりも外側の間隔を広げておき、これによって、小さい寸法のばね部でより大きな変形量を確保することができる。 Therefore, in the present invention, the part of the forward path in one round- trip of the wire in the left-right direction, which connects the two points that deviate from the center in the left-right direction in the left-right direction, is inclined in the front-rear direction. By forming in the extended shape, the space | interval of the outer side is expanded rather than an inner side, and, thereby, a bigger deformation amount can be ensured with the spring part of a small dimension.

以上の通り、本発明の電気コネクタによれば、小型化かつ耐久性の向上が達成される。   As described above, according to the electrical connector of the present invention, downsizing and improvement in durability are achieved.

以下、本発明の実施形態を説明する。   Embodiments of the present invention will be described below.

FIG. 2 is a plan view of one electrical contact shown in FIG. 1 with the upper wall surface of the housing cut away. 3 is a cross-sectional view of the electrical connector shown in FIG. 1 taken along the line XX shown in FIG.

さらに、図４は、図１に示す電気コネクタを構成するコンタクトの斜視図である。図５は、そのコンタクトの製造過程における、打抜き加工時のコンタクトの形状を示した斜視図である。   Further, FIG. 4 is a perspective view of contacts constituting the electrical connector shown in FIG. FIG. 5 is a perspective view showing the shape of the contact during the punching process in the manufacturing process of the contact.

この電気コネクタ１０は、ハウジング２０とコンタクト３０とから構成されている。ここに示す電気コネクタ１０にはコンタクト３０は３本収容されており、図１には、それら３本のコンタクト３０の接触部３１がハウジング２０から突出している。なお、コンタクト３０の数は３本以外の数、例えば４本であってもよい。この電気コネクタ１０は、携帯電話機（図示せず）に搭載されてバッテリと回路基板等を電気的に接続するためのコネクタである。コンタクト３０の接触部３１は、バッテリの接点と接触すると、ハウジング２０内に引っ込む方向に押された状態となる。   The electrical connector 10 includes a housing 20 and a contact 30. The electrical connector 10 shown here accommodates three contacts 30, and in FIG. 1, the contact portions 31 of the three contacts 30 protrude from the housing 20. The number of contacts 30 may be a number other than three, for example, four. The electrical connector 10 is a connector that is mounted on a mobile phone (not shown) to electrically connect a battery, a circuit board, and the like. When the contact portion 31 of the contact 30 comes into contact with the contact point of the battery, the contact portion 31 is pushed in the direction of retracting into the housing 20.

このコンタクト３０は、金属板材の打抜き加工および折曲げ加工を経て、図４に示す形状に形成される。図５には、このコンタクトの製造過程における打抜き加工後、かつ折曲げ加工前の状態が示されている。この図５に示されているのは、折曲げ加工後にコンタクトとして機能する形状に打抜き加工された板材であってコンタクトではないが、ここでは、折曲げ加工後のものと同じ符号を使って示し、かつ折曲げ加工後の名称を使って説明する。   This contact 30 is formed into a shape shown in FIG. 4 through a punching process and a bending process of a metal plate material. FIG. 5 shows a state after the punching process and before the bending process in the manufacturing process of the contact. FIG. 5 shows a plate material that has been punched into a shape that functions as a contact after bending and is not a contact. Here, the same reference numerals as those after bending are used. And it explains using the name after bending.

このコンタクト３０は、この図５に示す形状に打抜き加工された後、図４に示す形状に折曲げ加工される。   The contact 30 is punched into the shape shown in FIG. 5 and then bent into the shape shown in FIG.

このコンタクト３０は、その前方に接触部３１が形成され、その接触部３１の後方にばね部３２が形成されている。さらにばね部３２の後方には固定部３３および端子部３４が形成されている。   The contact 30 has a contact portion 31 formed in front thereof and a spring portion 32 formed behind the contact portion 31. Further, a fixed portion 33 and a terminal portion 34 are formed behind the spring portion 32.

接触部３１は、上述の通り、前方に突出し相手接点（ここではバッテリの接点を想定している）に接触してその相手接点からの後方への押圧を受ける部分である。   As described above, the contact portion 31 is a portion that protrudes forward and contacts a mating contact (assuming a battery contact here) and receives a backward pressure from the mating contact.

また、ばね部３２は、接触部３１が、相手接点から押圧を受けたときに弾性的に変形する部分である。   Moreover, the spring part 32 is a part which elastically deforms when the contact part 31 receives a press from the other party contact.

また、固定部３３は、このコンタクト３０がハウジング２０内に差し込まれたときにハウジング２０内に圧入されてハウジング２０の内壁に圧接し、このコンタクト３０をハウジング２０内の所定位置に固定するための部分である。固定部３３の端縁には圧入突起３３１が設けられている。   The fixing portion 33 is pressed into the housing 20 when the contact 30 is inserted into the housing 20 and presses against the inner wall of the housing 20 to fix the contact 30 at a predetermined position in the housing 20. Part. A press-fitting protrusion 331 is provided on the end edge of the fixing portion 33.

さらに、端子部３４は、図２，図３に示すようにハウジング２０の後方から露出し、回路基板等（図示せず）との間の電気的接続を担う部分である。   Furthermore, the terminal part 34 is a part which is exposed from the back of the housing 20 as shown in FIGS. 2 and 3 and is responsible for electrical connection with a circuit board or the like (not shown).

ここで、ばね部３２は、図５に示す打抜き時点では、線材が左右方向に繰り返し折り返しながら前後に延びた形状を有する。そしてこのばね部３２は、折曲げ加工を経ることにより、図４に示すように、打抜き時点における左右方向の折り返し部分３２１がそのばね部３２の他の部分と対面する向きに折り曲げられている。ばね部３２は、接触部３１が相手接点に押されるたびに伸縮する。このため、打抜き加工時に形成されたコンタクトの破断面がハウジングの内壁面に接している従来構造の場合は、ハウジングの内壁面が繰り返し削られるおそれがあり、耐久性に問題がある。これに対し、本実施形態では、折り返し部分３２１がそのばね部３２の他の部分と対面する向きに折り曲げられているため、ばね部３２が伸縮しても破断面でハウジング２０の内壁面が削られることが緩和され、耐久性が向上する。また、ばね部３２が図４に示す形状に折り曲げられることからコンタクト３０の外形が小型化され、電気コネクタ１０の全体の小型化が図られる。   Here, at the time of punching shown in FIG. 5, the spring portion 32 has a shape in which the wire extends back and forth while being repeatedly folded back in the left-right direction. The spring portion 32 is bent in a direction in which the folded portion 321 in the left-right direction at the time of punching faces the other portions of the spring portion 32 as shown in FIG. The spring portion 32 expands and contracts every time the contact portion 31 is pushed by the mating contact. For this reason, in the case of the conventional structure in which the fractured surface of the contact formed during the punching process is in contact with the inner wall surface of the housing, the inner wall surface of the housing may be repeatedly scraped, and there is a problem in durability. On the other hand, in the present embodiment, since the folded portion 321 is bent in a direction facing the other portion of the spring portion 32, the inner wall surface of the housing 20 is cut at the fracture surface even if the spring portion 32 expands or contracts. Is alleviated and durability is improved. Further, since the spring portion 32 is bent into the shape shown in FIG. 4, the outer shape of the contact 30 is reduced, and the overall size of the electrical connector 10 is reduced.

尚、その折り返し部分３２１は、この実施形態では他の部分と対面する向きに折り曲げられているが、折り返し部分３２１は、スペースに余裕があるときはさらに深く折り曲げられていてもよい。   The folded portion 321 is bent in the direction facing the other portions in this embodiment. However, the folded portion 321 may be bent deeper if there is enough space.

このばね部３２はさらに、このばね部３２を形成する線材どうしの間隔にも特徴を有する。ここでは、図２，図４に示すように、このばね部３２を形成する打抜き時点における１つの折り返し部分３２１の内側の前後方向の間隔をｄ１とし、打抜き時点における前後方向に互いに隣接する折り返し部分３２１どうしの前後方向の間隔をｄ２とする。このとき、ばね部３２は、ｄ１＜ｄ２となっている。   The spring portion 32 is further characterized by the distance between the wires forming the spring portion 32. Here, as shown in FIGS. 2 and 4, the distance in the front-rear direction inside one folded portion 321 at the time of punching that forms the spring portion 32 is d1, and the folded portions adjacent to each other in the front-rear direction at the time of punching. The interval in the front-rear direction between 321 is d2. At this time, the spring portion 32 satisfies d1 <d2.

接触部３１が相手接点に押されてばね部３２が縮んだとき、折り返し部分３２１が相対的に高い剛性を有し変形の抵抗として働く。すなわち、ばね部３２が縮んだとき、折り返し部分３２１の内側（寸法ｄ１の部分）と外側（寸法ｄ２の部分）とを比べると、内側（寸法ｄ１の部分）よりも外側（寸法ｄ２の部分）の方が前後方向に大きく縮む。このため、ｄ１＝ｄ２の場合は、ばね部３２が縮んだとき外側（寸法ｄ２の部分）の方が先に線材どうしが接触してそれ以上縮めない状態となる。   When the contact portion 31 is pushed by the mating contact and the spring portion 32 contracts, the folded portion 321 has relatively high rigidity and acts as a deformation resistance. That is, when the spring portion 32 is contracted, the inner side (part of dimension d1) and the outer side (part of dimension d2) of the folded portion 321 are compared to the outer side (part of dimension d1). Shrinks greatly in the front-rear direction. For this reason, in the case of d1 = d2, when the spring part 32 contracts, the outer side (the part of the dimension d2) comes into contact with the wires first and cannot be further contracted.

本実施形態ではｄ１＜ｄ２となっているため、ｄ１＝ｄ２の場合と比べ、より小さい寸法のばね部３２でより大きな変形量を確保することができる。   Since d1 <d2 in the present embodiment, a larger amount of deformation can be ensured with the spring portion 32 having a smaller size than when d1 = d2.

尚、ここでは、携帯電話機に内蔵することを予定した電気コネクタを取り上げて説明したが、本発明の電気コネクタは携帯電話機用に限らず、広く適用できるものである。   Here, the electrical connector that is planned to be built in the mobile phone has been described. However, the electrical connector of the present invention is not limited to the mobile phone and can be widely applied.
