Description

本発明は、各種の電子機器に搭載される回路基板に取り付けられ、電線ケーブルなどの電気伝送体を電気的に接続するための基板用コネクタ、及び基板用コネクタ構造に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board connector mounted on a circuit board mounted on various electronic devices and used to electrically connect an electric transmission body such as a wire cable, and a board connector structure.

従来の基板用コネクタ（以下「コネクタ」ともいう。）として、コネクタハウジングに保持されるコネクタ端子が直角に屈曲され、その屈曲された先のコネクタ端子の先端が回路基板の接続孔に挿通されて半田付けされる水平タイプのものが知られている（例えば、特許文献１参照）。この種のコネクタは、コネクタハウジングが回路基板の周縁部に取り付けられる際、その開口部が回路基板の水平面に沿って外側に向けて開口して配置される。 In conventional board connectors (hereinafter also referred to as "connectors"), connector terminals held in a connector housing are bent at right angles, and the bent ends of the connector terminals are inserted into connection holes in a circuit board. A horizontal type that is soldered is known (see Patent Document 1, for example). In this type of connector, when the connector housing is attached to the peripheral portion of the circuit board, the opening is arranged to open outward along the horizontal surface of the circuit board.

また、回路基板へのコネクタの実装の際、作業装置はコネクタハウジングを吸着した状態で、平板状に形成される回路基板の水平面に対しその垂直方向（以下「高さ方向」又は「上下方向」ともいう。）で回路基板にコネクタハウジングを載置する。そのため、従来のコネクタは、回路基板に対し積層されて実装される。 Further, when the connector is mounted on the circuit board, the working device sucks the connector housing and moves vertically (hereinafter referred to as "height direction" or "vertical direction") with respect to the horizontal plane of the flat plate-shaped circuit board. ) to place the connector housing on the circuit board. Therefore, conventional connectors are stacked and mounted on a circuit board.

なお、通常、作業装置は、回路基板の水平面に沿ってコネクタをスライドして取り付けることはない。スライドでの取付の場合、コネクタ端子の先端が回路基板に強く押圧されて過剰に屈曲する可能性がある。このとき、コネクタが回路基板に対し歪んで浮いてしまうなど、コネクタ端子の半田付けが困難となってしまう。 Normally, the working device does not attach the connector by sliding it along the horizontal plane of the circuit board. In the case of mounting by sliding, the tip of the connector terminal may be strongly pressed against the circuit board and bent excessively. At this time, the connector is distorted and floats on the circuit board, making it difficult to solder the connector terminals.

特開２０００－２１７２２７号公報JP-A-2000-217227

上記特許文献１のような従来のコネクタでは、コネクタ端子は、コネクタの開口部で回路基板の水平面に対しその垂直方向（以下「上下方向」ともいう。）で複数列で保持される。この場合、上下方向の保持位置に応じて互いに屈曲位置が異なる、複数種類のコネクタ端子をそれぞれ用意する必要がある。そのため、コストの増加、及び組立の煩雑化に繋がる可能性があり、改善の余地があった。 In a conventional connector such as that disclosed in Patent Document 1, connector terminals are held in a plurality of rows in a direction perpendicular to a horizontal plane of a circuit board (hereinafter also referred to as "vertical direction") in an opening of the connector. In this case, it is necessary to prepare a plurality of types of connector terminals each having different bending positions depending on the holding position in the vertical direction. Therefore, it may lead to an increase in cost and complication of assembly, and there is room for improvement.

また、近年、各種の電子機器に搭載される回路基板は、その電子機器の小型化に伴って高密度化、省スペース化が強く要求されるようになっている。上述したように、従来の基板用コネクタは、回路基板に積層して実装されるため、コネクタハウジングにコネクタ端子を多数保持させる仕様などにおいて、コネクタ実装時での高さ方向の寸法（背）が高くなる場合があり、実装時の低背化の点で改善の余地があった。 In recent years, circuit boards mounted on various electronic devices are strongly required to have higher density and space saving as the electronic devices are becoming smaller. As mentioned above, conventional board connectors are stacked and mounted on a circuit board. There is room for improvement in terms of lowering the height at the time of mounting.

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、コネクタ端子の種類の共通化を図って用意すべき種類数を削減して標準化を実現するとともに、実装時のコネクタの低背化を実現することができる基板用コネクタ、及び基板用コネクタ構造を提供することにある。 SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and its object is to standardize the types of connector terminals by reducing the number of types to be prepared, and to realize standardization of the connectors during mounting. An object of the present invention is to provide a board connector and a board connector structure capable of achieving a low profile.

One pair 23A of the two pairs of support bulging portions 23A and 23B is arranged at the front end portion of the outer wall surface 22 on both left and right sides of the connector housing 20. As shown in FIG. The other pair 23B is arranged at the rear ends of the outer wall surfaces 22 on both the left and right sides. Each of the support swelling portions 23A and 23B is provided so as to swell outward in the left-right direction from each of the outer wall surfaces 22 . The support bulging portions 23A and 23B are formed in a substantially rectangular block shape that bulges from the upper end to the lower end of the outer wall surface 22 as a whole. The support bulging portion 23B at the rear end portion further bulges outward in the front-rear direction. Due to this bulging, a gap S is formed between the outer wall surface 22 (back surface) on the rear side of the connector housing 20 and the inner wall portion 4 of the notch portion 3 of the circuit board 2 (FIGS. 6 and 7). reference).

支持膨出部２３Ａ，２３Ｂそれぞれにおいて、外壁面２２から膨出した基端部には係止溝２４が形成されている。係止溝２４は、コネクタハウジング２０の上側の外壁面２２に向けて開口しており、前後方向で隣接する支持膨出部２３Ａ，２３Ｂそれぞれに向かい合う内側面に、支持膨出部２３Ａ，２３Ｂの上端から下方に向けて所定距離の深さに亘って延びる。また、係止溝２４の幅（左右方向の寸法）は係合ペグ３０の係止片３２（図３参照）が収容可能に設定されている。 A locking groove 24 is formed in each of the support bulging portions 23A and 23B at the base end portion bulging from the outer wall surface 22. As shown in FIG. The locking groove 24 is open toward the outer wall surface 22 on the upper side of the connector housing 20, and the support bulges 23A and 23B are provided on the inner side surfaces facing the support bulges 23A and 23B adjacent in the front-rear direction. It extends downward from the upper end over a depth of a predetermined distance. The width (dimension in the left-right direction) of the locking groove 24 is set so that the locking piece 32 (see FIG. 3) of the engaging peg 30 can be accommodated therein.

図３に示すように、係合ペグ３０は、回路基板２に固定されており、コネクタハウジング２０の支持膨出部２３Ａ，２３Ｂを係止する。また、係合ペグ３０は、銅やステンレスなどの金属製の板状部材を曲げ加工させて形成される。すなわち、係合ペグ３０は、一端部に拡幅部分を有する略矩形状の平板部材の他端部を、１箇所で略直角に折り曲げ加工して形成される。これにより、係合ペグ３０は、その折曲部分よりも一方側に配置される係止部３１と、折曲部分よりも他方側に配置される載置部３３と、を有して構成される。 As shown in FIG. 3, the engagement pegs 30 are fixed to the circuit board 2 and engage the support bulges 23A and 23B of the connector housing 20. As shown in FIG. Further, the engaging peg 30 is formed by bending a metal plate member such as copper or stainless steel. That is, the engagement peg 30 is formed by bending the other end of a substantially rectangular flat plate member having a widened portion at one end at a substantially right angle. Thus, the engaging peg 30 is configured to have a locking portion 31 arranged on one side of the bent portion and a mounting portion 33 arranged on the other side of the bent portion. be.

係止部３１は、コネクタハウジング２０の支持膨出部２３Ａ，２３Ｂに係止してコネクタハウジング２０が回路基板２から上方向に離脱不能にする。係止部３１の拡幅部分であり前後方向に延びる係止片３２は、支持膨出部２３Ａ，２３Ｂの係止溝２４に挿入され、支持膨出部２３Ａ，２３Ｂを上方から係止する。係止片３２の厚さは、支持膨出部２３Ａ，２３Ｂそれぞれの係止溝２４に挿入可能とするため、その係止溝２４の幅（左右方向の寸法）よりも若干薄く設けられる。また、係止片３２の幅（上下方向の寸法）は、支持膨出部２３Ａ，２３Ｂから露出しないように係止溝２４の深さ（上下方向の寸法）よりも若干短く設けられる。そして、載置部３３は、回路基板２の表面に載置されて、回路基板２に係合ペグ３０を固定する。載置部３３は、回路基板２の載置凹部７に嵌め込まれて、接着剤又は半田により接着固定されている。このように、係合ペグ３０は、コネクタハウジング２０の上方向への離脱を防止するようになっているものの、コネクタハウジング２０が切り欠き部３に収容されている状態で下方向の力が加わった際におけるコネクタハウジング２０を保持する力は弱く、コネクタハウジング２０の離脱を確実に防止することができない。そこで、本発明の実施形態に係るコネクタハウジング２０は、当接延出部２５Ａ，２５Ｂ，２５Ｃを備えることによって、後述するように、コネクタハウジング２０が切り欠き部３に収容されている状態で下方向の力が加わっても回路基板２に確実に支持されるようになっている。 The locking portions 31 are locked to the support bulging portions 23A and 23B of the connector housing 20 so that the connector housing 20 cannot be separated from the circuit board 2 upward. A locking piece 32 extending in the front-rear direction, which is a widened portion of the locking portion 31, is inserted into the locking groove 24 of the support bulges 23A and 23B to lock the support bulges 23A and 23B from above. The thickness of the locking piece 32 is set slightly thinner than the width (horizontal dimension) of the locking groove 24 so that it can be inserted into the locking groove 24 of each of the support bulges 23A and 23B. The width (vertical dimension) of the locking piece 32 is slightly shorter than the depth (vertical dimension) of the locking groove 24 so as not to be exposed from the support bulges 23A and 23B. The mounting portion 33 is mounted on the surface of the circuit board 2 to fix the engaging peg 30 to the circuit board 2 . The mounting portion 33 is fitted into the mounting concave portion 7 of the circuit board 2 and fixed by adhesive or solder. In this way, although the engaging peg 30 prevents the connector housing 20 from being detached upward, a downward force is applied to the connector housing 20 while the connector housing 20 is accommodated in the notch portion 3 . The force for holding the connector housing 20 is weak when the connector housing 20 is closed, and the detachment of the connector housing 20 cannot be reliably prevented. Therefore, the connector housing 20 according to the embodiment of the present invention is provided with the abutting extensions 25A, 25B, and 25C so that the connector housing 20 can be lowered when the connector housing 20 is accommodated in the notch portion 3, as will be described later. Even if a directional force is applied, it is reliably supported by the circuit board 2. - 特許庁

Each is fixed and connected (see FIG. 7). In addition, the plurality of connector terminals 10 are arranged at the base ends of the component connection portions 12 (peripheral boundaries between the component connection portions 12 and the connecting portions 13), on the opposite side of the opening 21 of the connector housing 20. It is held by the side walls 26 . The component connection portions 12 of the connector terminal 10 each protrude in the front-rear direction inside the opening portion 21 . The connecting portion 13 of the connector terminal 10 is arranged in the gap S and exposed to the outside.

本実施形態では、８本のコネクタ端子１０は、上下方向で２列で並んで保持される。すなわち、上側の列に（一部の）４本のコネクタ端子１０が回路基板２の水平面、つまり左右方向に沿って並列配置される。下側の列に（他部の）４本が左右方向に沿って並列配置される。具体的には、その同種類において、上側のコネクタ端子１０（オフセット端子）それぞれの部品接続部１２の軸芯Ｃ２は、その基板接続部１１の軸芯Ｃ１よりも上側（回路基板２の水平面に対し交差する方向でその一方側）に配置される。その一方、下側のコネクタ端子１０それぞれの部品接続部１２の軸芯Ｃ２は、その基板接続部１１の軸芯Ｃ１よりも下側（その他方側）に配置される。そして、上述したように、コネクタハウジング２０は、回路基板２の切り欠き部３にその一部分で重畳して収容される。このようなコネクタ１の構造により、コネクタ端子１０は、同形状の同種類の場合でもコネクタハウジング２０において上下方向で２列で保持されることになる。 In this embodiment, the eight connector terminals 10 are arranged in two rows in the vertical direction and held.

With such a structure of the connector 1, the connector terminals 10 are held in two rows in the vertical direction in the connector housing 20 even when they are of the same type and shape.

またこのとき、上側のコネクタ端子１０の基板接続部１１と部品接続部１２とを含む平面それぞれ、及び下側のコネクタ端子１０の基板接続部１１と部品接続部１２とを含む平面それぞれはともに、回路基板２の水平面に対し垂直に交差して設けられる。この垂直交差により、上側のコネクタ端子１０の部品接続部１２と下側のコネクタ端子１０の部品接続部１２との上下方向での離間距離は最大に設定可能となる。 Further, at this time, each of the planes including the board connection portion 11 and the component connection portion 12 of the upper connector terminal 10 and each of the planes including the board connection portion 11 and the component connection portion 12 of the lower connector terminal 10 are It is provided to intersect the horizontal plane of the circuit board 2 perpendicularly.

なお、第１及び第２の対の当接延出部２５Ａ，２５Ｂの延出量（左右方向の寸法）は略同一に設定されるが、第１の対の当接延出部２５Ａの幅（前後方向の寸法）は、第２の対の当接延出部２５Ｂよりも大きく設定される。 Similarly, the second pair of contact extensions 25B are located on the front surface side of the circuit board 2 at the rear end portions of the outer wall surfaces 22 on both the left and right sides thereof, and on the laterally outer side from the vertically intermediate portion thereof. is extended along The second pair of contact extensions 25</b>B are formed to protrude in a wing shape, and the rear surfaces of the contact extensions 25</b>B are in contact with the surface of the circuit board 2 .
The extension amount (horizontal dimension) of the first and second pairs of contact extensions 25A and 25B is set to be substantially the same, but the width of the first pair of contact extensions 25A (Dimension in the front-rear direction) is set larger than the second pair of contact extension portions 25B.

第３の対の当接延出部２５Ｃは、コネクタハウジング２０が回路基板２の切り欠き部３に収容された状態で、その後側の外壁面２２の左右両側端部において、回路基板２の表面側であり、且つその外壁面２２の上端から下端までに亘る部分から前後方向外側に沿って延設される。第３の対の当接延出部２５Ｃは、左右方向での側面視で略直角台形状の補強リブ部として形成されており、その底面が回路基板２の表面に当接される。 The third pair of contact extending portions 25C are formed on the surface of the circuit board 2 at both left and right ends of the outer wall surface 22 on the rear side when the connector housing 20 is accommodated in the cutout portion 3 of the circuit board 2. and extends outward in the front-rear direction from a portion extending from the upper end to the lower end of the outer wall surface 22 .

As described above, according to the board connector 1 and the board connector structure of the present embodiment, the board connector 1 is provided at one end and is electrically connected to the flat circuit board 2 . It has a board connecting portion 11 and a component connecting portion 12 provided at the other end for being electrically connected to a component to be connected of the mating connector, the board connecting portion 11 being a terminal connecting portion of the circuit board 2 . A plurality of connector terminals 10 connected and fixed to the circuit board 6 and a plurality of connector terminals 10 are held in two rows in the vertical direction (perpendicular to the horizontal plane of the circuit board 2), and formed on the circuit board 2. a connector housing 20 that is partially overlapped with the notch portion 3 and accommodated therein, and the plurality of connector terminals 10 are arranged such that the axis C1 of the board connection portion 11 and the axis C1 of the component connection portion 12 are aligned with each other. A component of the upper (partial) connector terminal 10 among the plurality of connector terminals 10, which is composed of a plurality of offset terminals having the same shape that are substantially parallel and offset in the intersecting direction.

The axis C2 of the component connection portion 12 of 10 is arranged below the axis C1 of the board connection portion 11 (on the other side).

このため、回路基板２に切り欠き部３が形成され、コネクタハウジング２０はその切り欠き部３にその一部分で重畳して収容されるので、コネクタハウジング２０を回路基板２上に積層して取り付ける構造と比べて、その実装時の高さ方向での全体寸法を短く（低背化）することができる。また、複数のコネクタ端子１０はオフセット端子により構成され、そのコネクタ端子１０は、互いに同一の形状に形成される１つの種類を有する。そして、コネクタハウジング２０は、回路基板２の切り欠き部３にその一部で重畳して収容されるため、その１つの種類のうち一部の部品接続部１２を上側（一方側）に、他部の部品接続部１２を下側（その一方とは逆方向の他方側）に配置することができる。この配置により、コネクタハウジング２０の開口部２１においてその１つの種類で２列配置することができる。その結果、コネクタ端子１０の種類の共通化を図って用意すべき種類数を削減することができる。すなわち、本構成によって、コネクタ端子１０の種類の共通化を図って用意すべき種類数を削減して標準化を実現するとともに、実装時のコネクタ１の低背化を実現することができる。 For this reason, the cutout portion 3 is formed in the circuit board 2, and the connector housing 20 is accommodated by partially overlapping the cutout portion 3, so that the connector housing 20 is stacked on the circuit board 2 and attached. Compared to , the overall dimension in the height direction at the time of mounting can be shortened (reduced in height). Moreover, the plurality of connector terminals 10 are constituted by offset terminals, and the connector terminals 10 are of one type formed in the same shape. Since the connector housing 20 is partially overlapped with the cutout portion 3 of the circuit board 2 and accommodated, some of the component connection portions 12 of the one type are on the upper side (one side), and the other is on the upper side (one side). The part connection part 12 of the part can be arranged on the lower side (the other side opposite to the one side). This arrangement allows two rows of one type to be arranged in the opening 21 of the connector housing 20 . As a result, it is possible to standardize the types of connector terminals 10 and reduce the number of types to be prepared. That is, with this configuration, standardization can be achieved by standardizing the types of connector terminals 10 to reduce the number of types to be prepared, and the height of the connector 1 can be reduced during mounting.

また、本実施形態の基板用コネクタ１及び基板用コネクタ構造によれば、複数のコネクタ端子１０（オフセット端子）の１つの同種類において、上側（一部）のコネクタ端子１０の基板接続部１１と部品接続部１２とを含む平面、及び下側（他部）のコネクタ端子１０の基板接続部１１と部品接続部１２とを含む平面は、回路基板２の水平面に対し垂直に交差する。このため、その上側のコネクタ端子１０の部品接続部１２とその下側のコネクタ端子１０の部品接続部１２との、上下方向（回路基板２の水平面に対する垂直方向）での離間距離は最大に設定することができる。 Further, according to the board connector 1 and the board connector structure of the present embodiment, in one of the plurality of connector terminals 10 (offset terminals) of the same type, the board connection portion 11 of the upper (partial) connector terminal 10 and the board connection portion 11 A plane including the component connection portion 12 and a plane including the board connection portion 11 and the component connection portion 12 of the lower (other portion) connector terminal 10 intersect perpendicularly with the horizontal plane of the circuit board 2 . Therefore, the separation distance in the vertical direction (perpendicular to the horizontal plane of the circuit board 2) between the component connection portion 12 of the connector terminal 10 on the upper side and the component connection portion 12 of the connector terminal 10 on the lower side is set to the maximum. can do.

また、本実施形態の基板用コネクタ１及び基板用コネクタ構造によれば、複数のコネクタ端子１０（オフセット端子）の１つの同種類において、上側（一部）のコネクタ端子１０及び下側（他部）のコネクタ端子１０（オフセット端子）は、左右方向（回路基板２の水平面）に沿って複数並設される。このとき、コネクタハウジング２０の開口部２１において同種類のコネクタ端子１０（オフセット端子）で２列配置できるので、特にそのコネクタ端子１０を左右方向に沿って複数並設する場合、取付部品の切替工程やセットミスなどを削減して作業の簡素化を顕著に図ることができる。 Further, according to the board connector 1 and the board connector structure of the present embodiment, in one of the plurality of connector terminals 10 (offset terminals) of the same type, the upper (partial) connector terminal 10 and the lower (other part) ) are arranged side by side along the left-right direction (horizontal plane of the circuit board 2). At this time, since the connector terminals 10 (offset terminals) of the same kind can be arranged in two rows in the opening 21 of the connector housing 20, especially when a plurality of the connector terminals 10 are arranged side by side along the left-right direction, the mounting part switching process It is possible to significantly simplify the work by reducing set errors and the like.

以上で具体的実施形態の説明を終えるが、本発明の態様はこれら実施形態に限定されるものではなく、適宜、変形、改良などが可能である。
例えば、上記実施形態では、コネクタ端子１０は全てオフセット端子のタイプとしたが、これに限定されない。コネクタ端子１０の一部にそれ以外のタイプ、例えばストレートタイプの端子が含まれてもよい。この場合、上下方向の複数の列で上下方向中心にそのストレートタイプの端子が保持される。 Although the description of specific embodiments has been completed above, aspects of the present invention are not limited to these embodiments, and modifications and improvements can be made as appropriate.
For example, in the above embodiment, all the connector terminals 10 are of the offset terminal type, but the present invention is not limited to this. Some of the connector terminals 10 may include other types, such as straight type terminals. In this case, the straight type terminals are held at the center in the vertical direction in a plurality of rows in the vertical direction.

また、コネクタ端子１０のオフセット端子の種類を１種類としたが、これに限定されない。オフセット量が異なるオフセット端子を複数種類を用いてもよい。この場合、上下方向の列でそのオフセット量に応じて入れ子構造で保持される。すなわち、オフセット量が最も大きいオフセット端子が上下方向の列で最上位及び最下位で保持される。次に大きいオフセット端子のその次の内側に順々に保持される。 Moreover, although the type of the offset terminal of the connector terminal 10 was one type, it is not limited to this. A plurality of types of offset terminals having different offset amounts may be used. In this case, they are held in a nested structure according to the amount of offset in vertical rows. That is, the offset terminals having the largest offset amount are held at the top and bottom positions in the vertical row. It is held inside the next next larger offset terminal in sequence.

また、複数対の当接延出部２５Ａ，２５Ｂ，２５Ｃを設けたが、これに限定されない。当接延出部２５Ａ，２５Ｂ，２５Ｃは、１対でもよく、また１つでもよいが、複数対の場合の方がより顕著に上述した作用効果を得ることができる。 Also, although the plurality of pairs of contact extensions 25A, 25B, and 25C are provided, the present invention is not limited to this. The number of contact extensions 25A, 25B, 25C may be one pair or one, but the above-described effect can be obtained more remarkably in the case of a plurality of pairs.

また、第３の対の当接延出部２５Ｃの両方をコネクタ端子１０の基板接続部１１の延在方向に沿って基板接続部１１を越えて延びるように設けたが、これに限定されない。その一方のみを越えて延びるように設けてもよいが、両方の場合の方がより顕著に上述した作用効果を得ることができる。 Further, both of the third pair of contact extension portions 25C are provided so as to extend beyond the board connection portion 11 along the extending direction of the board connection portion 11 of the connector terminal 10, but the present invention is not limited to this. It may be provided so as to extend beyond only one of them, but in both cases the effect described above can be obtained more significantly.
