Description

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

特許文献１には、接続相手である雄端子金具のタブを挿入させるための角筒部を備えた雌形の端子金具が開示されている。この端子金具は所定形状に打ち抜いた金属板材を曲げ加工して成形されており、角筒部は、底壁の左右両側縁から一対の側壁を略直角に立ち上げ、両側壁の上端縁から、幅寸法がほぼ同じである一対の上面壁を底壁と略平行に延出させた形態であり、一対の上面壁を上下に重ね合わせることにより、角筒部の形状が安定して保持されるようになっている。
特開２００１−３５７９２１号公報 Patent Document 1 discloses a female terminal fitting including a square tube portion for inserting a tab of a male terminal fitting which is a connection partner. This terminal fitting is formed by bending a metal plate material punched into a predetermined shape, and the square tube portion is raised from the left and right side edges of the bottom wall at a substantially right angle, and from the upper edge of both side walls, A pair of upper surface walls having substantially the same width dimension are extended substantially in parallel with the bottom wall, and the shape of the rectangular tube portion is stably maintained by superimposing the pair of upper surface walls vertically. It is like that.
JP 2001-357721 A

上記従来の端子金具は、角筒部が５枚の壁部で構成され、隣り合う壁部同士が前後方向の折り目で連なっているため、端子金具を曲げ加工する前の展開状態では、角筒部を構成する５枚の壁部が折り目と直角な幅方向に並ぶ形態となる。つまり、金属板材は、幅方向における寸法が大きくなる。   In the above conventional terminal fitting, the square tube portion is composed of five wall portions, and the adjacent wall portions are connected by a fold line in the front-rear direction. Therefore, in the expanded state before bending the terminal fitting, The five wall portions constituting the portion are arranged in the width direction perpendicular to the fold line. That is, the metal plate has a large dimension in the width direction.

一般に、端子金具の製造には、端子金具の幅方向に細長いキャリアの側縁から複数の金属板材を並列状に突出させた連鎖端子と称されるフープ材が用いられ、このフープ材では、角筒部を構成する全ての壁部の展開状態における幅方向の総寸法が大きい程、金属板材の並列ピッチが広くなり、並列ピッチが広い程、隣り合う金属板材の間のスペースも大きくなる。   In general, for the manufacture of terminal fittings, a hoop material called a chain terminal in which a plurality of metal plate members are projected in parallel from the side edges of a carrier elongated in the width direction of the terminal fitting is used. The larger the total dimension in the width direction in the unfolded state of all the wall portions constituting the cylindrical portion, the wider the parallel pitch of the metal plate materials, and the wider the parallel pitch, the larger the space between adjacent metal plate materials.

この隣り合う金属板材の間のスペースは、金属板材を所定形状に打ち抜くのに伴って材料が廃棄された領域に相当する。そのため、上記従来のように５枚の壁部で角筒部を構成しているものでは、廃棄材料の面積が大きくなり、材料の歩留まりが悪いという問題がある。   The space between the adjacent metal plate materials corresponds to a region where the material is discarded as the metal plate material is punched into a predetermined shape. Therefore, in the case where the square tube portion is constituted by five wall portions as in the conventional case, there is a problem that the area of the waste material is increased and the yield of the material is poor.

本発明は上記のような事情に基づいて完成されたものであって、材料の歩留まりを低下させることなく、角筒部を安定した形状に保持できるようにすることを目的とする。   The present invention has been completed based on the above circumstances, and an object of the present invention is to enable the rectangular tube portion to be held in a stable shape without reducing the yield of the material.

上記の目的を達成するための手段として、請求項１の発明は、所定形状に打ち抜いた金属板材を曲げ加工して成形され、複数の壁部を前後方向の折り目に沿って曲げて構成された角筒部を有する端子金具であり、前記複数の壁部は、底壁と、前記底壁の左右両側縁から略直角に立ち上がる一対の側壁と、一方の前記側壁の立ち上がり端縁から他方の前記側壁に向けて略直角に延出する上面壁とによって構成されており、前記他方の側壁の立ち上がり端縁部と前記上面壁の延出端縁部のうち一方の端縁部には、他方の前記端縁部の外面に当接可能な第１係止部と、前記他方の端縁部の内面に当接可能な第２係止部とが形成され、前記折り目と直角な方向における前記第１係止部の寸法は、前記上面壁及び前記他方の側壁よりも小さく、前記折り目と直角な方向における前記第２係止部の寸法は、前記上面壁及び前記他方の側壁よりも小さいところに特徴を有する。   As a means for achieving the above object, the invention of claim 1 is formed by bending a metal plate material punched into a predetermined shape and bending a plurality of wall portions along folds in the front-rear direction. A terminal fitting having a rectangular tube portion, wherein the plurality of wall portions are a bottom wall, a pair of side walls that rise substantially at right angles from right and left side edges of the bottom wall, and a rising edge of one side wall to the other side. An upper surface wall extending substantially at right angles toward the side wall, and one of the rising end edge of the other side wall and the extended end edge of the upper surface wall has the other end A first locking portion capable of contacting the outer surface of the end edge portion and a second locking portion capable of contacting the inner surface of the other end edge portion are formed, and the first locking portion in a direction perpendicular to the fold line is formed. The dimension of one locking part is smaller than the upper surface wall and the other side wall, The dimensions of the second engagement portion in a direction perpendicular is characterized at less than the upper wall and said other side wall.

請求項２の発明は、請求項１に記載のものにおいて、前記他方の端縁部は、その前記第１係止部との当接領域を内側へ段差状に変位させた形態とされているところに特徴を有する。   According to a second aspect of the present invention, in the first aspect, the other end edge portion is configured such that a contact area with the first locking portion is displaced inwardly in a step shape. However, it has characteristics.

請求項３の発明は、請求項１または請求項２に記載のものにおいて、前記一方の端縁部は、前記角筒部の角縁に沿ったエッジ部を有しており、前記第２係止部は、前記一方の端縁部を含む前記壁部の一部を、窓孔が開口するように内側へ切り起こすことによって形成されているところに特徴を有する。   According to a third aspect of the present invention, in the first or second aspect of the present invention, the one end edge portion has an edge portion along a corner edge of the rectangular tube portion, and the second engagement portion. The stop portion is characterized in that a part of the wall portion including the one end edge portion is formed by cutting inward so that the window hole is opened.

＜請求項１の発明＞
一方の端縁部に形成した第１係止部と第２係止部が、他方の端縁部を外面側と内面側から挟むので、角筒部は安定した形状に保たれる。第１係止部と第２係止部は、いずれも、折り目と直角な方向における寸法が、上面壁及び他方の側壁よりも小さく設定されている。したがって、金属板材の曲げ加工前の展開状態における折り目と直角な方向の角筒部の寸法は、幅寸法がほぼ同じである一対の上面壁を含む５枚の壁部で構成されている角筒部に比べると、小さく抑えられている。これにより、フープ材の状態において隣り合う金属板材の並列ピッチを小さくして、金属板材を打ち抜く際の廃棄材料の面積を小さく抑え、材料歩留まりの向上を図ることができる。 <Invention of Claim 1>
Since the first locking portion and the second locking portion formed at one end edge sandwich the other end edge from the outer surface side and the inner surface side, the square tube portion is kept in a stable shape. Each of the first locking portion and the second locking portion is set to have a smaller dimension in a direction perpendicular to the fold than the upper surface wall and the other side wall. Therefore, the square tube portion in the direction perpendicular to the crease in the unfolded state before bending the metal plate material has a square tube made up of five wall portions including a pair of upper surface walls having substantially the same width size. Compared to the part, it is kept small. Thereby, the parallel pitch of the adjacent metal plate materials in the state of the hoop material can be reduced, the area of the waste material when punching the metal plate material can be suppressed, and the material yield can be improved.

＜請求項２の発明＞
他方の端縁部のうち第１係止部との当接領域を内側へ段差状に変位させたので、第１係止部の外面と、他方の端縁部のうち第１係止部と非対応の領域の外面とを、概ね面一状の位置関係とすることができる。 <Invention of Claim 2>
Since the contact area with the first locking portion of the other edge is displaced stepwise inward, the outer surface of the first locking portion and the first locking portion of the other edge The outer surface of the non-corresponding region can have a substantially flush positional relationship.

＜請求項３の発明＞
一方の端縁部は、角筒部の角縁に沿ったエッジ部を有しているが、このエッジ部に大きな凹部が形成されていると、端子金具をハウジングに挿入する場合などにエッジ部において引っ掛かりが生じることが懸念される。この点に鑑み、本発明では、一方の端縁部を含む壁部の一部を、窓孔が開口するように内側へ切り起こすことによって、第２係止部を形成している。これにより、一方の端縁部のエッジ部は、凹部が存在せず、真っ直ぐに連なった形態となるので、端子金具をハウジングに挿入する場合などに、角筒部の角縁において引っ掛かりが生じ難くなる。 <Invention of Claim 3>
One edge has an edge along the corner of the rectangular tube. If a large recess is formed in this edge, the edge is used when inserting the terminal fitting into the housing. There is concern about the occurrence of catching. In view of this point, in the present invention, the second locking portion is formed by raising a part of the wall portion including one end edge portion inward so that the window hole is opened. As a result, the edge portion of one end edge portion has no recess and is formed in a straight line, so that when the terminal fitting is inserted into the housing, it is difficult for the corner portion of the rectangular tube portion to be caught. Become.

＜実施形態１＞
以下、本発明を具体化した実施形態１を図１乃至図５を参照して説明する。本実施形態の端子金具１０の製造に際しては、端子金具１０の幅方向に細長く延びるキャリア２の側縁から所定形状に打ち抜かれた複数の金属板材３を並列状に突出させた連鎖端子と称されるフープ材１が用いられる。 <Embodiment 1>
A first embodiment embodying the present invention will be described below with reference to FIGS. When manufacturing the terminal fitting 10 of the present embodiment, it is referred to as a chain terminal in which a plurality of metal plate members 3 punched in a predetermined shape from the side edge of the carrier 2 elongated in the width direction of the terminal fitting 10 are projected in parallel. A hoop material 1 is used.

端子金具１０の前端側部分は、雄形の相手側端子（図示せず）のタブを挿入させるための角筒部１１となっており、後端側部分は、電線９を圧着により接続するためのオープンバレル状の圧着部１２となっている。   The front end portion of the terminal fitting 10 is a rectangular tube portion 11 for inserting a tab of a male counterpart terminal (not shown), and the rear end portion is for connecting the electric wire 9 by crimping. The open barrel-shaped crimping portion 12 is formed.

角筒部１１は、前後方向の折り目４を介して連なる４枚の壁部によって構成されている。壁部は、いずれも前後方向に細長く概ね方形をなしている。４枚の壁部は、圧着部１２の前端に連なる底壁１３と、底壁１３の右側縁から略直角に立ち上がる右側壁１４（本発明の構成要件である一方の側壁）と、底壁１３の左側縁から略直角に立ち上がる左側壁１５（本発明の構成要件である他方の側壁）と、右側壁１４の上端縁（立ち上がり端縁）から左側壁１５に向けて略直角に（即ち、底壁１３と平行に）延出する上面壁１６とによって構成されている。   The rectangular tube portion 11 is constituted by four wall portions that are continuous via a fold line 4 in the front-rear direction. Each wall portion is elongated in the front-rear direction and has a substantially rectangular shape. The four wall portions are a bottom wall 13 connected to the front end of the crimping portion 12, a right side wall 14 (one side wall which is a constituent element of the present invention) rising from the right side edge of the bottom wall 13, and the bottom wall 13. The left side wall 15 rising from the left side edge of the right side wall (the other side wall which is a constituent element of the present invention) and the right side wall 14 from the upper end edge (rising end edge) toward the left side wall 15 (ie, bottom) And a top wall 16 extending parallel to the wall 13.

左側壁１５には、その立ち上がり端縁部１５Ｅ（本発明の構成要件である一方の端縁部）から右側壁１４に向かって直角に延出する第１係止部１７が形成されている。前後方向における第１係止部１７の形成領域は、左側壁１５の前端から略中央位置に亘る範囲である。第１係止部１７の幅寸法（折り目４と直角な方向の寸法）は、角筒部１１を構成する４枚の壁部（底壁１３、右側壁１４、左側壁１５及び上面壁１６）のいずれよりも小さい寸法である。   The left side wall 15 is formed with a first locking portion 17 extending at a right angle from the rising end edge 15E (one end edge which is a constituent element of the present invention) toward the right side wall 14. A region where the first locking portion 17 is formed in the front-rear direction is a range extending from the front end of the left side wall 15 to a substantially central position. The width dimension of the first locking part 17 (the dimension in the direction perpendicular to the crease 4) is the four wall parts (the bottom wall 13, the right side wall 14, the left side wall 15 and the upper side wall 16) constituting the rectangular tube part 11. It is a dimension smaller than any of these.

また、上面壁１６における左側壁１５と対応する延出端縁部１６Ｅ（本発明の構成要件である他方の端縁部）には、前後方向及び左右方向において第１係止部１７と対応する領域を下方（角筒部１１の内側）へ段差状に叩き出した形態の受け部１８が形成されている。この受け部１８は、上面壁１６と平行であり、上面壁１６に対して第１係止部１７の板厚寸法分だけ低くなるように高さ設定されている。この受け部１８の上面には、第１係止部１７の下面が面当たり状に当接している。   Further, the extended end edge 16E (the other end edge which is a constituent element of the present invention) corresponding to the left side wall 15 in the upper surface wall 16 corresponds to the first locking portion 17 in the front-rear direction and the left-right direction. A receiving portion 18 is formed in such a manner that the region is knocked downward (inside the rectangular tube portion 11) in a stepped shape. The receiving portion 18 is parallel to the upper surface wall 16 and is set so as to be lower than the upper surface wall 16 by the thickness of the first locking portion 17. On the upper surface of the receiving portion 18, the lower surface of the first locking portion 17 is in contact with the surface.

左側壁１５の立ち上がり端縁部１５Ｅには、その一部を内側へ直角に切り起こした形態の第２係止部１９が形成されている。第２係止部１９は、前後方向に長い方形をなし、前後方向における第２係止部１９の形成領域は、第１係止部１７よりも後方の位置から、左側壁１５の後端よりも少し前方の位置に亘っている。また、第２係止部１９の幅寸法は、角筒部１１を構成する底壁１３、右側壁１４、左側壁１５及び上面壁１６のいずれよりも小さい寸法である。   The rising edge 15E of the left side wall 15 is formed with a second locking portion 19 having a part thereof cut and raised at a right angle. The second locking part 19 has a rectangular shape that is long in the front-rear direction, and the formation area of the second locking part 19 in the front-rear direction is from a position behind the first locking part 17 from the rear end of the left side wall 15. Is also slightly ahead. Further, the width dimension of the second locking portion 19 is smaller than any of the bottom wall 13, the right side wall 14, the left side wall 15, and the upper surface wall 16 constituting the rectangular tube portion 11.

また、左側壁１５の上端縁部のうち第２係止部１９を切り起こした部分は、前後方向に長い方形の窓孔２０として開口されている。第２係止部１９は、左側壁１５の上端縁から上面壁１６の板厚寸法分だけ下方の折り目５に沿って曲げられている。したがって、第２係止部１９の上面は、上面壁１６の延出端縁部１６Ｅの下面に対して面当たり状に当接しており、これにより、上面壁１６の延出端縁部１６Ｅは第２係止部１９を介して左側壁１５により下支えされている。   Further, a portion of the upper end edge of the left side wall 15 where the second locking portion 19 is cut and raised is opened as a rectangular window hole 20 that is long in the front-rear direction. The second locking portion 19 is bent along the crease 5 below the upper wall of the upper wall 16 from the upper edge of the left wall 15. Therefore, the upper surface of the second locking portion 19 is in contact with the lower surface of the extended end edge portion 16E of the upper surface wall 16 so that the extended end edge portion 16E of the upper surface wall 16 is in contact with the lower surface. It is supported by the left side wall 15 via the second locking part 19.

上述のように、左側壁１５の立ち上がり端縁部１５Ｅ（上端縁部）には、上面壁１６の延出端縁部１６Ｅ（左端縁部）に対して上面側から当接する第１係止部１７と下面側から当接する第２係止部１９とが、前後に位置をずらした配置で形成されている。また、延出端縁部１６Ｅのうち第１係止部１７よりも後方の領域、即ち第２係止部１９と対応する領域は、金属板材３を打ち抜いたときに切断端面が上向きに（上面壁１６と平行に）露出しており、この切断端面の左側のエッジ部２１は、角筒部１１の角縁部の一部を構成している。   As described above, the rising edge 15E (upper edge) of the left wall 15 is in contact with the extended edge 16E (left edge) of the upper wall 16 from the upper surface side. 17 and the 2nd latching | locking part 19 contact | abutted from the lower surface side are formed in the arrangement | positioning which shifted the position back and forth. Further, in the extended end edge portion 16E, a region behind the first locking portion 17, that is, a region corresponding to the second locking portion 19, has a cut end face upward when the metal plate material 3 is punched (upper surface). The edge portion 21 on the left side of the cut end face constitutes a part of the corner edge portion of the rectangular tube portion 11.

次に、本実施形態の作用を説明する。
４つの壁部１３，１４，１５，１６を曲げ加工して角筒部１１を成形した状態では、左側壁１５の立ち上がり端縁部１５Ｅに形成した第１係止部１７が上面壁１６の受け部１８の外面に当接することにより、上面壁１６の上方への開きが防止されるとともに、左側壁１５の立ち上がり端縁部１５Ｅに形成した第２係止部１９が上面壁１６の内面に当接することにより、上面壁１６の下方への変位が防止され、これにより、角筒部１１は正規の形状に安定して保たれる。 Next, the operation of this embodiment will be described.
In a state in which the four cylindrical wall portions 13, 14, 15, 16 are bent to form the rectangular tube portion 11, the first locking portion 17 formed on the rising edge 15 </ b> E of the left side wall 15 is received by the top wall 16. By contacting the outer surface of the portion 18, the upper surface wall 16 is prevented from opening upward, and the second locking portion 19 formed on the rising edge 15 </ b> E of the left side wall 15 contacts the inner surface of the upper surface wall 16. By contacting, the downward displacement of the upper surface wall 16 is prevented, whereby the rectangular tube portion 11 is stably maintained in a regular shape.

上記のように本実施形態の端子金具１０の製造に際しては、フープ材１が用いられているが、このフープ材１では、角筒部１１の展開状態における幅寸法（折り目４と直角な方向の寸法）が大きい程、金属板材３の並列ピッチが広くなり、並列ピッチが広い程、隣り合う金属板材３の間のデッドスペースも大きくなる。特に、圧着部１２の幅寸法は、角筒部１１を構成する全ての壁部１３，１４，１５，１６の幅方向における総寸法よりも小さいので、圧着部１２の左右両側方のデッドスペースが大きくなる。この隣り合う金属板材３の間のデッドスペースは、金属板材３を所定形状に打ち抜くのに伴って材料が廃棄された領域に相当するものであるため、廃棄面積を小さく抑えて材料の歩留まりの向上を図るためには、角筒部１１の展開状態における幅寸法を小さく抑えることが必要である。   As described above, the hoop material 1 is used in the manufacture of the terminal fitting 10 of the present embodiment. In this hoop material 1, the width dimension (in the direction perpendicular to the crease 4) in the expanded state of the rectangular tube portion 11 is used. The larger the dimension) is, the wider the parallel pitch of the metal plates 3 is, and the wider the parallel pitch is, the larger the dead space between the adjacent metal plates 3 is. In particular, since the width dimension of the crimping part 12 is smaller than the total dimension in the width direction of all the wall parts 13, 14, 15, 16 constituting the rectangular tube part 11, the dead spaces on both the left and right sides of the crimping part 12 are growing. The dead space between the adjacent metal plate members 3 corresponds to a region where the material is discarded as the metal plate member 3 is punched into a predetermined shape. Therefore, the waste area is reduced and the yield of the material is improved. In order to achieve this, it is necessary to keep the width dimension of the expanded state of the rectangular tube portion 11 small.

そこで、本実施形態では、角筒部１１を安定した形状に保つための手段として、左側壁１５の立ち上がり端縁部１５Ｅに形成した第１係止部１７と第２係止部１９を上面壁１６の外面と内面に当接させることによって、上面壁１６の枚数を１枚だけとし、さらに、第１係止部１７と第２係止部１９の幅寸法を、上面壁１６よりも小さくした。この構成によれば、幅寸法がほぼ同じである一対の上面壁を含む５枚の壁部で構成されている角筒部に比べると、金属板材３の曲げ加工前の展開状態における角筒部１１の幅寸法が小さく抑えられる。これにより、フープ材１の状態において隣り合う金属板材３の並列ピッチを小さくして、金属板材３を打ち抜く際の廃棄材料の面積を小さく抑え、材料歩留まりの向上を図ることができる。   Therefore, in the present embodiment, as means for keeping the rectangular tube portion 11 in a stable shape, the first locking portion 17 and the second locking portion 19 formed on the rising edge 15E of the left side wall 15 are provided on the upper surface wall. By contacting the outer surface and the inner surface of 16, the number of the upper surface walls 16 is only one, and the width dimensions of the first locking portion 17 and the second locking portion 19 are made smaller than those of the upper surface wall 16. . According to this configuration, the square tube portion in the unfolded state of the metal plate 3 before bending is compared with a square tube portion configured by five wall portions including a pair of upper surface walls having substantially the same width dimension. The width dimension of 11 can be kept small. Thereby, in the state of the hoop material 1, the parallel pitch of the adjacent metal plate material 3 can be made small, the area of the waste material when the metal plate material 3 is punched out can be suppressed, and the material yield can be improved.

尚、本実施形態では、上面壁１６の延出端縁部１６Ｅは、その第１係止部１７との当接領域を内側へ段差状に変位させた形態の受け部１８としているが、これにより、第１係止部１７の外面と、上面壁１６の延出端縁部１６Ｅのうち第１係止部１７と非対応の領域の外面とを、概ね面一状の位置関係とすることが実現されている。   In the present embodiment, the extended edge 16E of the upper surface wall 16 is a receiving portion 18 having a shape in which the contact area with the first locking portion 17 is displaced inwardly in a step shape. Thus, the outer surface of the first locking portion 17 and the outer surface of the non-corresponding region of the extended end edge portion 16E of the upper surface wall 16 have a substantially flush positional relationship. Is realized.

また、左側壁１５の立ち上がり端縁部１５Ｅは、角筒部１１の角縁に沿ったエッジ部２１を有しているが、このエッジ部２１に大きな凹部が形成されていると、端子金具１０をハウジングに挿入する場合などにエッジ部２１において引っ掛かりが生じることが懸念される。この点に鑑み、本実施形態では、左側壁１５の一部を、窓孔２０が開口するように内側へ切り起こすことによって、第２係止部１９を形成した。この構成によれば、左側壁１５のエッジ部２１は、大きな凹部が存在せずに、真っ直ぐに連なった形態となるので、端子金具１０をハウジング等に挿入する際に、角筒部１１の角縁において引っ掛かりが生じることを回避できる。   Further, the rising edge 15E of the left side wall 15 has an edge portion 21 along the corner edge of the rectangular tube portion 11. If a large recess is formed in the edge portion 21, the terminal fitting 10 There is a concern that the edge portion 21 may be caught when the is inserted into the housing. In view of this point, in the present embodiment, the second locking portion 19 is formed by cutting a part of the left side wall 15 inward so that the window hole 20 opens. According to this configuration, the edge portion 21 of the left side wall 15 does not have a large concave portion, and has a form that is straightly connected. Therefore, when the terminal fitting 10 is inserted into a housing or the like, the corner of the rectangular tube portion 11 is formed. It is possible to avoid the occurrence of catching at the edge.
