Description

本発明は、電子機器等の配線接続に用いる給電用コネクタに関する。   The present invention relates to a power feeding connector used for wiring connection of an electronic device or the like.

給電用コネクタは、電力を効率よく伝えるために、相手側プラグと低電気抵抗で接続することが求められている。その要求を満たすために、相手側プラグとの接点を複数にすると共に接点における接圧を高くすることが通常行われている。図13(A),(B)は従来の給電用コネクタの一例を示す。図13(A)では多接点接触導電部材52と導体筐体53とからなる給電用コネクタ51がプリント基板30に固着されており、ケーブル45端部の相手側プラグ40を差し込む前の状態が示される。図13(B)は相手側プラグ40を差し込んだ状態であり、導体筐体53が半断面として示される。従来の給電用コネクタは多接点接触導電部材52と導体筐体53とを備える。多接点接触導電部材52は、両端の円環を複数の帯状体で接続した略円筒形をなし、複数の帯状体が内側に湾曲して相手側プラグとの接点を構成している。導体筐体53は、多接点接触導電部材52円環部分を前後に摺動可能に収容し、相手側プラグが多接点接触導電部材52に差し込まれたときに帯状体が外側に押し広げられて両端の円環部分がそれぞれ離間する方向に移動できるように構成している。また、導体筐体53は、プリント基板30上の端子に、例えば、半田付けにより搭載されている。   The power supply connector is required to be connected to the counterpart plug with low electrical resistance in order to efficiently transmit power. In order to satisfy this requirement, it is common practice to use a plurality of contacts with the mating plug and increase the contact pressure at the contacts. 13A and 13B show an example of a conventional power feeding connector. FIG. 13A shows a state before the power supply connector 51 including the multi-contact contact conductive member 52 and the conductor housing 53 is fixed to the printed circuit board 30 and the mating plug 40 at the end of the cable 45 is inserted. It is. FIG. 13B shows a state in which the mating plug 40 is inserted, and the conductor housing 53 is shown as a half section. The conventional power feeding connector includes a multi-contact contact conductive member 52 and a conductor housing 53. The multi-contact contact conductive member 52 has a substantially cylindrical shape in which the circular rings at both ends are connected by a plurality of strips, and the plurality of strips are curved inward to form a contact with the mating plug. The conductor housing 53 slidably accommodates the ring contact portion of the multi-contact contact conductive member 52, and when the mating plug is inserted into the multi-contact contact conductive member 52, the band-like body is pushed outward. It is comprised so that the annular part of both ends can move to the direction which each separates. The conductor housing 53 is mounted on a terminal on the printed circuit board 30 by, for example, soldering.

このような多接点接触導電部材52と導体筐体53とからなる給電用コネクタ51は、相手側プラグとの接点を複数にすると共に接点における接圧を高くするために特殊な構造の多接点接触導電部材52を必要とし、さらに、多接点接触導電部材52を保持する導体筐体53が必要となるため、高価なものとなる。   The power feeding connector 51 including the multi-contact contact conductive member 52 and the conductor housing 53 has a special multi-contact contact in order to make a plurality of contacts with the mating plug and to increase the contact pressure at the contacts. Since the conductive member 52 is required and the conductor casing 53 that holds the multi-contact contact conductive member 52 is required, the conductive member 52 is expensive.

また、下記特許文献1には、金属板の打ち抜き及び曲げ加工からなるパワーポート端子が示されているが、充分な接触圧力を確保できる端子構造となっていない。   Moreover, although the power port terminal which consists of stamping and bending of a metal plate is shown by the following patent document 1, it does not have a terminal structure which can ensure sufficient contact pressure.

下記特許文献2には、金属端子部の周囲を絶縁ハウジングで囲ったパワーポート端子が示されているが、絶縁ハウジングを設けるため製造工数が多くなり、コスト高になる。   Patent Document 2 below shows a power port terminal in which a metal terminal portion is surrounded by an insulating housing. However, since an insulating housing is provided, the number of manufacturing steps is increased and the cost is increased.

図1乃至図8を用いて本発明に係る給電用コネクタの第1の実施の形態を説明する。これらの図において、給電用コネクタ1は、1枚の導電性の平板からなる導電部材(例えば、銅合金等の金属板)を打ち抜いて、曲げ加工を施すことによって形成されており、前側躯体2及び後側躯体3と、前側及び後側躯体2,3を相互に連結する連結部4,5,6と、前側躯体2から後側躯体3に向けて延長するように形成された弾性接触子7,8,9とを備えている。   A first embodiment of a power feeding connector according to the present invention will be described with reference to FIGS. In these drawings, the power supply connector 1 is formed by punching a conductive member (for example, a metal plate such as a copper alloy) made of a single conductive flat plate and bending it. And the rear housing 3, the connecting parts 4, 5, 6 that connect the front and rear housings 2, 3 to each other, and the elastic contacts formed to extend from the front housing 2 toward the rear housing 3. 7, 8, and 9.

前側躯体2は方形枠状に折り曲げて形成され、この前側躯体2の前面を覆うように前側躯体2の方形枠状部分の上辺部から下方に折り曲げてフロントカバー10が形成され、図2の相手側プラグ40と係合する係合部としてのフック11がフロントカバー10の両側から前方に向かって設けられるとともに、フロントカバー10の下部から取付部としてのはんだ付け用リード部12が下方に延長するように形成されている。また、フロントカバー10の下部に別の取付部としてのはんだ付け用パッド13が前方に折り曲げて形成されている。フロントカバー10にはプラグ40の差込口10aが形成されている。プラグ40は、ケーブル45の端部に電気接続されており、円柱状嵌合部41とこの基端側に形成されたフランジ部42とを有している。フロントカバー10の差込口10aは、プラグ40の円柱状嵌合部41よりも大径で且つフランジ部42よりも小径に形成され、プラグ40が差込口10aに差し込まれたときにフランジ42がフロントカバー10に係合する。フック11はフロントカバー10の左右両側に配置されていて、差し込まれたプラグ40のフランジ部42と係合して、プラグ40の抜け出しを防止する機能を有する。   The front housing 2 is formed by being bent into a rectangular frame shape, and a front cover 10 is formed by bending downward from the upper side of the rectangular frame-shaped portion of the front housing 2 so as to cover the front surface of the front housing 2. A hook 11 as an engaging portion that engages with the side plug 40 is provided forward from both sides of the front cover 10, and a soldering lead portion 12 as an attachment portion extends downward from the lower portion of the front cover 10. It is formed as follows. Further, a soldering pad 13 as another attachment portion is formed at the lower portion of the front cover 10 by bending forward. The front cover 10 is formed with an insertion port 10 a for the plug 40. The plug 40 is electrically connected to the end portion of the cable 45, and has a cylindrical fitting portion 41 and a flange portion 42 formed on the base end side. The insertion port 10a of the front cover 10 is formed to have a larger diameter than the cylindrical fitting portion 41 of the plug 40 and a smaller diameter than the flange portion 42, and the flange 42 when the plug 40 is inserted into the insertion port 10a. Engages with the front cover 10. The hooks 11 are disposed on both the left and right sides of the front cover 10 and have a function of preventing the plug 40 from coming out by engaging with the flange portion 42 of the inserted plug 40.

連結部4,5,6には、前側及び後側躯体2,3間の距離を縮めるための折曲部が形成されている。すなわち、左右の連結部4,5は外側に凸となるように曲げ加工され、連結部6は内側(上側)に凸となるように曲げ加工されている。このように前側及び後側躯体2,3間の距離を縮めることで、前側躯体2から延びる弾性接触子7,8,9が後側躯体3の内側に入り込むことを可能にしている。連結部6は給電用コネクタ1に差し込まれた相手側プラグ40に当接して上下方向の位置決めを行う馬台(リッジドラック)となり、補強のために長手方向に楕円形のリブ6aが形成されている。リブ6aはプラグ40に対向する面に凸部となるように形成されている。リブ6aは2つ形成され、それぞれプラグ40下面の左右に当接してプラグ40の左右方向の位置決めを行っている。 The connecting portions 4, 5, 6 are formed with bent portions for reducing the distance between the front and rear housings 2, 3. That is, the left and right connecting portions 4 and 5 are bent so as to protrude outward, and the connecting portion 6 is bent so as to protrude inward (upward). By reducing the distance between the front and rear housings 2 and 3 in this manner, the elastic contacts 7, 8 and 9 extending from the front housing 2 can enter the inside of the rear housing 3. The connecting portion 6 becomes a mount ( ridged drag ) that contacts the mating plug 40 inserted into the power supply connector 1 and performs vertical positioning, and an elliptical rib 6a is formed in the longitudinal direction for reinforcement. Yes. The rib 6a is formed to be a convex portion on the surface facing the plug 40. Two ribs 6a are formed, and contact the left and right sides of the lower surface of the plug 40 to position the plug 40 in the left-right direction.

後部躯体3も方形枠状に折り曲げて形成され、後部躯体3の左右側辺部の下部から取付部としてのはんだ付け用リード部3aがそれぞれ下方に延長するように形成されている。前側躯体2から後側躯体3に向けて延長する弾性接触子7,8,9はいずれも内側に向けて凸面となるように湾曲しており、かつ先端が後部躯体3の方形枠状部分の内側に位置している。   The rear housing 3 is also formed by being bent into a rectangular frame shape, and soldering lead portions 3a as attachment portions are formed to extend downward from the lower portions of the left and right side portions of the rear housing 3 respectively. The elastic contacts 7, 8, 9 extending from the front housing 2 toward the rear housing 3 are curved so as to be convex toward the inside, and the tip is a rectangular frame-shaped portion of the rear housing 3. Located inside.

図2及び図8に示すように、給電用コネクタ1はプリント基板30の取付穴31にリード部12及びリード部3aを挿入し、はんだ付けすることでプリント基板30に固定される。また、プリント基板30側に表面実装用電極32が形成されていれば、給電用コネクタ1側のはんだ付け用パッド13も表面実装用電極32にはんだ付けすることで固着される。   As shown in FIGS. 2 and 8, the power feeding connector 1 is fixed to the printed circuit board 30 by inserting the lead part 12 and the lead part 3 a into the mounting hole 31 of the printed circuit board 30 and soldering. If the surface mounting electrode 32 is formed on the printed circuit board 30 side, the soldering pad 13 on the power feeding connector 1 side is also fixed to the surface mounting electrode 32 by soldering.

図2及び図8(A)のように、ケーブル45の端部に設けられたプラグ40を、給電用コネクタ1のフロントカバー10の差込口10aから後部躯体3方向に挿入することで、図8(B),(C)のようにプラグ40と給電用コネクタ1との電気接続を行うことができる。図8(A)の拡大図示部に示すようにプラグ40が挿入される前は、弾性接触子7は後部躯体3の内側に位置しているが、その内面に弾接してはいない。一方、図8(B)の拡大図示部に示すようにプラグ40が挿入されると、プラグ40の円柱状嵌合部41が弾性接触子7に当接して弾性接触子7を外側に向かって押し拡げ、弾性接触子7の先端が後部躯体3の内面に弾接する。このため、弾性接触子7はプラグ40に接する側が凸面となった実質的に従来の多接点接触導電部材52と同様な両持ちばね(両端が支持されているばね)として機能する。弾性接触子8,9も弾性接触子7と同様に両持ちばねとして機能する。弾性接触子7による両持ちばねの機能によって弾性接触子7と連結部6との間でプラグ40の円柱状嵌合部41を上下方向から挟み込むと共に弾性接触子8,9による両持ちばねの機能によって弾性接触子8と弾性接触子9との間でプラグ40の円柱状嵌合部41を左右方向から挟み込む。これによって、給電用コネクタ1は複数の箇所でプラグ40と接触することが可能となる。さらに、各弾性接触子7,8,9の両持ちばねの機能によって、プラグ40の円柱状嵌合部41に対して充分な接触圧力で接触することが可能となる。つまり、低電気抵抗での接続が可能となっている。また、フロントカバー10の左右両側に形成されたフック11は、挿入されたプラグ40のフランジ部42と係合して、プラグ40の抜け出しを防止する。   As shown in FIGS. 2 and 8 (A), the plug 40 provided at the end of the cable 45 is inserted into the rear housing 3 from the insertion port 10a of the front cover 10 of the power feeding connector 1. Electrical connection between the plug 40 and the power feeding connector 1 can be performed as shown in 8 (B) and (C). Before the plug 40 is inserted as shown in the enlarged view of FIG. 8A, the elastic contact 7 is positioned inside the rear housing 3, but is not elastically in contact with the inner surface thereof. On the other hand, when the plug 40 is inserted as shown in the enlarged view of FIG. 8B, the columnar fitting portion 41 of the plug 40 contacts the elastic contact 7 so that the elastic contact 7 faces outward. The tip of the elastic contact 7 is elastically brought into contact with the inner surface of the rear housing 3. For this reason, the elastic contactor 7 functions as a doubly-supported spring (a spring in which both ends are supported) which is substantially the same as the conventional multi-contact contact conductive member 52 whose convex surface is in contact with the plug 40. The elastic contacts 8 and 9 also function as double-supported springs like the elastic contact 7. The function of the double-supported spring by the elastic contacts 8 and 9 while sandwiching the cylindrical fitting portion 41 of the plug 40 from the vertical direction between the elastic contact 7 and the connecting portion 6 by the function of the double-supported spring by the elastic contact 7. Thus, the cylindrical fitting portion 41 of the plug 40 is sandwiched between the elastic contact 8 and the elastic contact 9 from the left and right directions. As a result, the power feeding connector 1 can come into contact with the plug 40 at a plurality of locations. Furthermore, it is possible to contact the cylindrical fitting portion 41 of the plug 40 with a sufficient contact pressure by the function of the double-supported springs of the respective elastic contacts 7, 8, 9. That is, connection with low electrical resistance is possible. The hooks 11 formed on the left and right sides of the front cover 10 engage with the flange portion 42 of the inserted plug 40 to prevent the plug 40 from coming out.

本実施の形態によれば、下記の効果を奏することができる。   According to the present embodiment, the following effects can be achieved.

(1) 給電用コネクタ1は、導電部材としての1枚の銅合金等の金属板を打ち抜いて曲げ加工を施すことによって形成されており、部品点数が1点であって廉価に供給することが可能で、量産性にも優れる。 (1) The power supply connector 1 is formed by punching a metal plate such as a copper alloy as a conductive member and bending it, so that the number of parts is one and can be supplied at low cost. It is possible and excellent in mass productivity.

(2) 前側及び後側躯体2,3間を連絡する連結部4,5,6には、距離を縮めるための折曲部が形成され、前側躯体2から後側躯体3に向けて延長する弾性接触子7,8,9の先端は後側躯体3の内側に位置する。このため、相手側プラグ40が給電用コネクタ1に挿入され、嵌合状態となった時は、弾性接触子7,8,9の先端が後部躯体3の内面に弾接してプラグ40に接する側が凸面となった両持ちばねとして機能し、プラグ40に対して充分大きな接触圧力で接する。この結果、プラグ40との間で低電気抵抗での接続を可能にしている。 (2) The connecting portions 4, 5, 6 connecting the front and rear housings 2, 3 are formed with bent portions for reducing the distance, and extend from the front housing 2 toward the rear housing 3. The tips of the elastic contacts 7, 8, 9 are located inside the rear housing 3. For this reason, when the mating plug 40 is inserted into the power supply connector 1 and is in the fitted state, the side where the tips of the elastic contacts 7, 8, 9 are in elastic contact with the inner surface of the rear housing 3 and are in contact with the plug 40. It functions as a double-sided spring having a convex surface, and contacts the plug 40 with a sufficiently large contact pressure. As a result, it is possible to connect the plug 40 with a low electrical resistance.

(3) 連結部6は、相手側プラグ40の位置決めを行う馬台となっており、挿入されたプラグ40の位置を確実に規制することができる。 (3) The connecting portion 6 serves as a mount for positioning the mating plug 40 and can reliably regulate the position of the inserted plug 40.

(4) 前側躯体2の前側に差込口10aを有するフロントカバー10が形成され、フロントカバー10の左右両側に係合部としてのフック11が形成されているため、一対のフック11がプラグ40側のフランジ部42と係合して、プラグ40が抜けないように挟持することができる。これにより、給電用コネクタ1とプラグ40との連結状体を確実に維持することが可能となる。 (4) Since the front cover 10 having the insertion port 10a is formed on the front side of the front housing 2 and the hooks 11 as the engaging portions are formed on the left and right sides of the front cover 10, the pair of hooks 11 are plugs 40. The plug 40 can be held so as not to come off by engaging with the flange portion 42 on the side.

この第2の実施の形態によれば、前側及び後側躯体2,3間を連絡する左右の連結部4,5が弾性接触子8,9を挟んで2本形成されているため、強度の向上を図ることができる。   According to the second embodiment, since the two right and left connecting portions 4 and 5 connecting the front and rear housings 2 and 3 are formed with the elastic contacts 8 and 9 interposed therebetween, the strength is increased. Improvements can be made.

図11及び図12で本発明の第3の実施の形態を説明する。図11及び図12の給電用コネクタ1Bは図9及び図10の給電用コネクタ1Aの前後方向の寸法を短縮したものである。前側及び後側躯体2,3間の連結部4,5,6や弾性接触子7,8,9を短くするとともに後側躯体3の前後の幅を短縮している。馬台となる連結部6には相手側プラグに対向する面に円形の凸部6bが形成されている。その他の構成は第2の実施の形態で示した給電用コネクタ1Aと同様である。   A third embodiment of the present invention will be described with reference to FIGS. The power supply connector 1B shown in FIGS. 11 and 12 is obtained by shortening the dimension in the front-rear direction of the power supply connector 1A shown in FIGS. The connecting portions 4, 5, 6 and the elastic contacts 7, 8, 9 between the front and rear housings 2, 3 are shortened, and the front-rear width of the rear housing 3 is shortened. A circular convex portion 6b is formed on the surface of the connecting portion 6 serving as a mount on the surface facing the mating plug. Other configurations are the same as those of the power feeding connector 1A shown in the second embodiment.

この第3の実施の形態によれば、前後方向が短縮された給電用コネクタ1Bとなるため、これを装着するプリント基板側の設置面積を縮小することができる。   According to the third embodiment, since the power supply connector 1B is shortened in the front-rear direction, it is possible to reduce the installation area on the printed circuit board side on which the power supply connector 1B is mounted.

以上、実施の形態を例に本発明を説明したが、実施の形態の各構成要素や各処理プロセスには請求項に記載の範囲で種々の変形が可能であることは当業者に理解されるところである。以下、変形例について触れる。   The present invention has been described above by taking the embodiment as an example. However, it is understood by those skilled in the art that various modifications can be made to each component and each processing process of the embodiment within the scope of the claims. By the way. Hereinafter, modifications will be described.

各実施の形態では、弾性接触子は前側躯体から後側躯体に向けて延長しているが、逆に後側躯体から前側躯体に向けて延長して先端を前側躯体の内側に入り込むように形成してもよい。また、複数の弾性接触子のうち一部の弾性接触子が前側躯体から後側躯体に向けて延長し、残りの弾性接触子は後側躯体から前側躯体に向けて延長する構成であってもよい。弾性接触子の本数は各実施の形態では3本であるが、本数は適宜増減可能である。   In each embodiment, the elastic contact extends from the front housing to the rear housing, but conversely extends from the rear housing to the front housing so that the tip enters the inside of the front housing. May be. Further, some of the plurality of elastic contacts may extend from the front housing to the rear housing, and the remaining elastic contacts may extend from the rear housing to the front housing. Good. The number of elastic contacts is three in each embodiment, but the number can be increased or decreased as appropriate.
