Description

本明細書によって開示される技術は、樹脂成形品に関する。 The techniques disclosed herein relate to resin articles.

Ｌ字状に曲げ形成された曲げ部を有する導電板と合成樹脂製のコネクタハウジングとが一体に固定されるように形成された端子台として、特開２０１２−１９５０６７号公報（下記特許文献１）に記載ものが知られている。
この端子台を組み立てる際には、まず、金属板材をプレス加工によって打ち抜いて曲げ加工を施すことにより、Ｌ字状に曲がった導電板を形成する。導電板を形成したところで、導電板を成形金型内にセットし、成形金型内に成形樹脂を流し込んで１次モールド成形によって１次成形体を成形する。そして、この１次成形体を中子として２次モールド成形することでコネクタハウジングを成形する。 As a terminal block formed so that a conductive plate having a bent portion formed by bending in an L shape and a connector housing made of synthetic resin are integrally fixed, Japanese Patent Application Laid-Open No. 2012-195067 (Patent Document 1 below). The ones described in are known.
When assembling this terminal block, first, a metal plate material is punched out by press working and bent to form an L-shaped curved conductive plate. When the conductive plate is formed, the conductive plate is set in the molding die, the molding resin is poured into the molding die, and the primary molded body is molded by the primary molding. Then, the connector housing is molded by secondary molding using this primary molded body as a core.

ところで、上記の端子台において、導電板の板厚を厚くした場合、曲げ部を成形する際に、曲げ部の幅方向両側の側面には外側に膨出する余肉が形成されてしまう。このため、曲げ部の位置において、成形樹脂を食い切ってコネクタハウジングを成形しようとすると、曲げ部の余肉が成形金型と干渉することで、成形金型内に導電板をセットできなくなってしまう。 By the way, in the above-mentioned terminal block, when the thickness of the conductive plate is increased, when the bent portion is formed, a surplus wall that bulges outward is formed on both side surfaces of the bent portion in the width direction. For this reason, if the molding resin is cut off at the position of the bent portion to form the connector housing, the surplus thickness of the bent portion interferes with the molding die, and the conductive plate cannot be set in the molding die. It ends up.

だからといって、余肉が生じることを考慮して、曲げ部の幅寸法を予め幅狭に成形しておくと、曲げ部の側面における余肉の量が少なかった場合には、曲げ部の幅寸法が所定の幅寸法よりも小さくなり、曲げ部の位置において樹脂を食い切ることができずに樹脂漏れが生じてしまう。 However, if the width dimension of the bent portion is formed narrow in advance in consideration of the occurrence of surplus thickness, the width dimension of the bent portion will be reduced when the amount of surplus wall on the side surface of the bent portion is small. It becomes smaller than the predetermined width dimension, and the resin cannot be completely consumed at the position of the bent portion, resulting in resin leakage.

本明細書では、導電板などの金属部材を成形金型内にセット可能にすると共に、意図しない部分への樹脂漏れを防止する技術を開示する。 In the present specification, a technique for enabling a metal member such as a conductive plate to be set in a molding die and preventing resin leakage to an unintended portion is disclosed.

本明細書によって開示される技術は、板状の金属部材と合成樹脂製の樹脂部とが一体に固定された樹脂成形品であって、前記樹脂部に設けられ、前記金属部材において板厚方向に沿って延びる側部の一部を埋設するモールド部と、前記側部の縁部に平面状に設けられ、前記モールド部から露出するように前記モールド部と隣り合って配された平面部と、前記側部において前記平面部を境に前記モールド部とは反対側に配され、前記平面部よりも減肉された減肉部とを備えている構成とした。
また、本明細書によって開示される技術は、板状の金属部材と合成樹脂製の樹脂部とが一体に固定された樹脂成形品の製造方法であって、金属部材にプレス加工を施すことにより形成されたプレス加工部の縁部に平面状に加工した平面部を形成し、当該平面部に前記樹脂部を成形する成形金型を接触させて成形樹脂を食い切ることでプレス加工部の側部に樹脂漏れが生じることを規制する構成とした。 The technique disclosed in the present specification is a resin molded product in which a plate-shaped metal member and a resin portion made of synthetic resin are integrally fixed, and is provided on the resin portion in the plate thickness direction in the metal member. A mold portion for burying a part of a side portion extending along the above, and a flat portion provided on the edge portion of the side portion in a planar shape and arranged adjacent to the mold portion so as to be exposed from the mold portion. The side portion is arranged on the side opposite to the mold portion with the flat surface portion as a boundary, and has a wall thickness reduction portion that is thinner than the flat surface portion.
Further, the technique disclosed in the present specification is a method for manufacturing a resin molded product in which a plate-shaped metal member and a resin portion made of synthetic resin are integrally fixed, and by pressing the metal member. A flat surface portion processed into a flat surface is formed on the edge portion of the formed press-processed portion, and a molding die for molding the resin portion is brought into contact with the flat surface portion to cut off the molding resin to cut off the molding resin on the side of the press-processed portion. It is configured to regulate the occurrence of resin leakage in the part.

例えば、金属部材にプレス加工を施すと、プレス加工による歪みが金属部材の側部に生じることで、樹脂部を成形する成形金型内にセットできなくなる嫌いがある。ところが、金属部材において歪みが生じやすい側部には、平面状に加工された平面部が形成されているから、プレス加工部を成形金型内に適切にセットすることができる。
また、平面状の平面部に成形金型を接触させて成形樹脂を確実に食い切ることができるから、モールド部と隣り合うように配された平面部から意図しない部分へ樹脂漏れが生じることを防ぐことができる。 For example, when a metal member is pressed, strain due to the press working is generated on the side portion of the metal member, and there is a dislike that the resin portion cannot be set in the molding die for molding. However, since the flat surface portion processed into a flat surface is formed on the side portion of the metal member where distortion is likely to occur, the press-processed portion can be appropriately set in the molding die.
In addition, since the molding die can be brought into contact with the flat flat portion to surely cut off the molding resin, resin leakage may occur from the flat portion arranged adjacent to the mold portion to an unintended portion. Can be prevented.

本明細書によって開示される樹脂成形品は、以下の構成としてもよい。
前記平面部は、前記金属部材に折り曲げられた形態に設けられた曲げ部の側部に設けられており、前記モールド部は、前記曲げ部の内側の内曲面を埋設しており、前記平面部は、前記曲げ部の折り曲げ方向に沿って延びる縁部の内周縁部に設けられ、前記減肉部は、前記曲げ部の折り曲げ方向に沿って延びる縁部の外周縁部に設けられている構成としてもよい。
このような構成によると、樹脂部を成形する際に、前記曲げ部の両側縁部における内周縁部に設けられた平面部に成形金型を接触させて樹脂を食い切ることができるから、モールド部を成形する樹脂が曲げ部の内側の面から減肉部や曲げ部の外側の面に樹脂漏れすることを防ぐことができる。 The resin molded product disclosed by the present specification may have the following constitution.
The flat surface portion is provided on a side portion of a bent portion provided in a bent form on the metal member, and the molded portion has an inner curved surface inside the bent portion embedded therein. Is provided on the inner peripheral edge portion of the edge portion extending along the bending direction of the bent portion, and the wall thinning portion is provided on the outer peripheral edge portion of the edge portion extending along the bending direction of the bent portion. May be.
According to such a configuration, when molding the resin portion, the molding die can be brought into contact with the flat surface portions provided on the inner peripheral edges of both side edges of the bent portion to cut off the resin. It is possible to prevent the resin forming the portion from leaking from the inner surface of the bent portion to the thinned portion or the outer surface of the bent portion.

前記金属部材は、前記曲げ部の一端に連なる形態で相手方導電体に接続可能に設けられた平板状の接続部と、前記曲げ部の他端に連なって設けられた平板状の本体部とを備えた導電体であって、前記曲げ部は、前記接続部と前記本体部との間の角度が直角となるように折り曲げられた形態となっている構成としてもよい。
曲げ部の一端に接続部が設けられている場合、曲げ部において樹脂漏れが生じると、接続部の接続面に成形樹脂が付着し、相手方導電体と接続部との接続信頼性が低下してしまう虞がある。 The metal member has a flat plate-shaped connecting portion provided so as to be connected to the other conductor in a form connected to one end of the bent portion and a flat plate-shaped main body portion provided connected to the other end of the bent portion. The conductor may be provided and the bent portion may be bent so that the angle between the connecting portion and the main body portion is a right angle.
When a connecting portion is provided at one end of the bent portion, if a resin leak occurs at the bent portion, the molding resin adheres to the connecting surface of the connecting portion, and the connection reliability between the mating conductor and the connecting portion is lowered. There is a risk that it will end up.

しかしながら、上記のような構成によると、曲げ部が略直角に折り曲げられることで、曲げ部の側縁部において余肉が形成されたとしても、曲げ部の側縁部に平面部を形成し、平面部と成形金型との間において樹脂を食い切ることで曲げ部における樹脂漏れを防ぐことができ、接続部に成形樹脂が付着することを防ぐことができるから、プレス加工によって曲げ部を折り曲げることで曲げ部に歪みが生じる場合には、非常に有効である。 However, according to the above configuration, the bent portion is bent at a substantially right angle, so that even if a surplus is formed at the side edge portion of the bent portion, a flat surface portion is formed at the side edge portion of the bent portion. By cutting off the resin between the flat surface portion and the molding die, it is possible to prevent resin leakage at the bent portion and prevent the molding resin from adhering to the connecting portion. Therefore, the bent portion is bent by press working. This is very effective when the bent portion is distorted.

本明細書によって開示される技術によれば、金属板材を成形金型内にセット可能にしつつ、意図しない部分への樹脂漏れを防止する。 According to the technique disclosed herein, a metal plate material can be set in a molding die while preventing resin leakage to an unintended portion.

本実施形態は、車両に搭載される機器の図示しないケースに取り付けられる端子台（「樹脂成形品」の一例）１０を例示しており、端子台１０は、ケース内に配された図示しない機器側端子とワイヤハーネスの端末に設けられた図示しない相手方端子（「相手方導電体」の一例）とを中継するものである。なお、以下の説明において、左右方向とは、図２および図１０における左右方向を基準とし、上下方向とは、図２および図１０における上下方向を基準とする。また、前後方向とは、図５、図１１および図１７における左右方向を基準とし、図示左方を前方、図示右方を後方として説明する。 <Embodiment>
The embodiment will be described with reference to FIGS. 1 to 18.
This embodiment illustrates a terminal block (an example of a "resin molded product") 10 attached to a case (not shown) of a device mounted on a vehicle, and the terminal block 10 is a device (not shown) arranged in the case. It relays between the side terminal and the other terminal (an example of "the other conductor") provided on the terminal of the wire harness (not shown). In the following description, the left-right direction is based on the left-right direction in FIGS. 2 and 10, and the up-down direction is based on the up-down direction in FIGS. 2 and 10. Further, the front-rear direction will be described with reference to the left-right direction in FIGS. 5, 11 and 17, with the left side in the drawing as the front and the right side in the drawing as the rear.

端子台１０は、図１から図７に示すように、３本の端子（「金属部材」の一例）２０と、３本の端子２０を左右方向に並べた状態でそれぞれの端子２０と一体に固定された合成樹脂製のハウジング（「樹脂部」の一例）４０とを備えて構成されている。 As shown in FIGS. 1 to 7, the terminal block 10 is integrally integrated with the three terminals (an example of a "metal member") 20 and the three terminals 20 in a state of being arranged in the left-right direction. It is configured to include a fixed synthetic resin housing (an example of a "resin portion") 40.

各端子２０は、図１５から図１７に示すように、導電性に優れた厚肉の金属板材をプレス加工によって打ち抜いて曲げ加工などを施すことによって上下に長い帯状に形成されている。また、端子２０は、上下に延びる平板状の端子本体（「本体部」の一例）２１と、端子本体２１の上端に設けられた曲げ部（「プレス加工部」の一例）２２と、曲げ部２２から後方に延出された電線側接続部（「接続部」の一例）２３と、端子本体２１の下端部に設けられた平板状の機器側接続部２４とを備えて構成されている。なお、３本の端子２０のうち左右の端子２０は、端子本体２１の上側において左右方向に屈曲されているものの、その他の構造は共通するため、図１および図８における図示右側の端子２０を代表として説明する。 As shown in FIGS. 15 to 17, each terminal 20 is formed in a vertically long strip shape by punching a thick metal plate material having excellent conductivity by press working and bending it or the like. Further, the terminal 20 includes a flat plate-shaped terminal body (an example of a "main body") 21 extending vertically, a bent portion (an example of a "pressed portion") 22 provided at the upper end of the terminal body 21, and a bent portion. It is configured to include an electric wire side connection portion (an example of a "connection portion") 23 extending rearward from 22 and a flat plate-shaped device side connection portion 24 provided at the lower end portion of the terminal body 21. Of the three terminals 20, the left and right terminals 20 are bent in the left-right direction on the upper side of the terminal body 21, but the other structures are common. Therefore, the terminals 20 on the right side of the drawings in FIGS. 1 and 8 are used. I will explain as a representative.

端子本体２１は、図１および図５に示すように、端子本体２１の上端部および下端部を除く全ての部分がハウジング４０内に埋設されており、端子本体２１の上端部において上下方向に延びる左右方向両側の側面は、図１５および図１７に示すように、上下方向に真っ直ぐ延びる平坦な本体側平面部２５とされている。端子本体２１の上下方向略中央部には、図８、図１０および図１５に示すように、シール剤（図示せず）を付着させるシール被着部２６が設けられており、このシール被着部２６にシール剤を付着させてハウジング４０によって埋設することで、シール被着部２６とハウジング４０との界面が止水されるようになっている。 As shown in FIGS. 1 and 5, all parts of the terminal body 21 except for the upper end and the lower end of the terminal body 21 are embedded in the housing 40 and extend in the vertical direction at the upper end of the terminal body 21. As shown in FIGS. 15 and 17, the side surfaces on both sides in the left-right direction are flat main body-side flat portions 25 extending straight in the vertical direction. As shown in FIGS. 8, 10 and 15, a seal attachment portion 26 for attaching a sealant (not shown) is provided at a substantially central portion of the terminal body 21 in the vertical direction, and the seal attachment portion 26 is provided. By attaching a sealing agent to the portion 26 and burying it in the housing 40, the interface between the seal-attached portion 26 and the housing 40 is stopped from water.

曲げ部２２は、図５、図１１および図１５に示すように、端子本体２１の上端に連なると共に電線側接続部２３の前端に連なった形態とされており、端子本体２１の上端から後方に向けて略直角に折り曲げられた形態とされている。したがって、曲げ部２２における曲げ方向に延びる左右両側の側部２２Ａは、図１５および図１７に示すように、曲げ部２２の曲げ加工に伴って外周縁部が内周縁部よりも緩やかに湾曲した状態となっている。 As shown in FIGS. 5, 11 and 15, the bent portion 22 is connected to the upper end of the terminal main body 21 and to the front end of the electric wire side connecting portion 23, and is connected to the rear end from the upper end of the terminal main body 21. It is said to be bent at a substantially right angle. Therefore, as shown in FIGS. 15 and 17, the outer peripheral edge portion of the bent portion 22 extending in the bending direction is curved more gently than the inner peripheral edge portion as the bending portion 22 is bent. It is in a state.

電線側接続部２３は、図１５から図１７に示すように、平板状をなしており、電線側接続部２３において延出方向に延びる左右方向両側の側面は前後方向の延びる平坦な接続部側平面部２７とされている。電線側接続部２３の上面は相手方端子とボルト接続される接続面２８とされており、電線側接続部２３には、板厚方向である上下方向に貫通するボルト孔２９が設けられている。電線側接続部２３は、接続面２８に相手方端子が載置され、ボルト孔２９に図示しないボルトが挿通されて相手方端子とボルト接続されるようになっている。 As shown in FIGS. 15 to 17, the electric wire side connecting portion 23 has a flat plate shape, and the side surfaces of the electric wire side connecting portion 23 extending in the extending direction in the left-right direction are flat connecting portions extending in the front-rear direction. It is a flat surface portion 27. The upper surface of the electric wire side connecting portion 23 is a connecting surface 28 that is bolted to the other terminal, and the electric wire side connecting portion 23 is provided with a bolt hole 29 that penetrates in the vertical direction, which is the plate thickness direction. A mating terminal is placed on the connecting surface 28 of the electric wire side connecting portion 23, and a bolt (not shown) is inserted into the bolt hole 29 to be bolted to the mating terminal.

機器側接続部２４は、端子本体２１よりもやや前方にオフセットした形態で端子本体２１の下端部に設けられており、機器側端子とボルト接続可能とされている。
ハウジング４０は、図１、図３および図５に示すように、各端子２０の上端部を前後左右から覆う覆い部４１と、各端子２０の上端部と共に覆い部４１を全周に亘って囲む筒状部４２と、ケースに設けられた図示しない取付孔に嵌合される嵌合部４３とを備えて構成されている。 The device-side connection portion 24 is provided at the lower end portion of the terminal body 21 in a form offset slightly forward of the terminal body 21, and can be bolted to the device-side terminal.
As shown in FIGS. 1, 3 and 5, the housing 40 surrounds the covering portion 41 that covers the upper end portion of each terminal 20 from the front, back, left and right, and the covering portion 41 together with the upper end portion of each terminal 20 over the entire circumference. It is configured to include a tubular portion 42 and a fitting portion 43 that is fitted into a mounting hole (not shown) provided in the case.

覆い部４１は、電線側接続部２３における接続部側平面部２７の後端部２７Ａを除く下半分および曲げ部２２の内側の内曲面３０を埋設すると共に、端子本体２１における本体側平面部２５の上端部２５Ａおよび端子本体２１の前面における上端部を除く端子本体２１の上端寄りの部分を埋設するブロック状に形成されている。また、各覆い部４１は、隣り合う覆い部４１の間に設けられたリブ状の連結部４４によって連結されている。 The covering portion 41 embeds the lower half of the electric wire side connecting portion 23 except for the rear end portion 27A of the connecting portion side flat portion 27 and the inner curved surface 30 inside the bent portion 22, and also embeds the inner curved surface 30 of the terminal main body 21. It is formed in a block shape in which a portion near the upper end of the terminal body 21 excluding the upper end portion 25A and the upper end portion on the front surface of the terminal body 21 is embedded. Further, each covering portion 41 is connected by a rib-shaped connecting portion 44 provided between adjacent covering portions 41.

各覆い部４１の内部には、図５に示すように、ナットＮを収容するナット収容部４５が設けられている。ナットＮは、上下に開口する締結孔Ｎ１を有する角形状のナットであって、ナットＮの厚み寸法は、端子２０の板厚寸法の約２倍とされている。言い換えると、端子２０の板厚寸法は、ナットＮの厚み寸法の約半分に設定されている。 As shown in FIG. 5, a nut accommodating portion 45 for accommodating the nut N is provided inside each covering portion 41. The nut N is a square nut having a fastening hole N1 that opens up and down, and the thickness dimension of the nut N is about twice the plate thickness dimension of the terminal 20. In other words, the plate thickness dimension of the terminal 20 is set to about half the thickness dimension of the nut N.

ナット収容部４５は、上方および後方に開口して形成されており、後端開口からナットＮが圧入状態で収容されるようになっている。ナット収容部４５の上端開口は、電線側接続部２３によって塞がれた状態となっており、ナットＮがナット収容部４５内の正規の位置に収容されると、図５に示すように、電線側接続部２３の下面とナットＮの上面とが上下に接触した状態になると共に、電線側接続部２３のボルト孔２９とナットＮの締結孔Ｎ１とが同軸となるように設定されている。 The nut accommodating portion 45 is formed by opening upward and rearward, and the nut N is accommodated in a press-fitted state from the rear end opening. The upper end opening of the nut accommodating portion 45 is closed by the electric wire side connecting portion 23, and when the nut N is accommodated in a regular position in the nut accommodating portion 45, as shown in FIG. The lower surface of the electric wire side connecting portion 23 and the upper surface of the nut N are in contact with each other up and down, and the bolt hole 29 of the electric wire side connecting portion 23 and the fastening hole N1 of the nut N are set to be coaxial. ..

筒状部４２は、図１および図３に示すように、左右方向に横長で上方に開口すると共に下端部に底壁４６を有する有底の筒状に形成されており、筒状部４２の上端開口から底壁４６および端子２０の電線側接続部２３が上方に臨んだ状態となっている。底壁４６は、左右方向に横長な長円形状をなしており、底壁４６の中央には左右方向に並ぶ３つの覆い部４１が底壁４６と一体となるように配置されている。 As shown in FIGS. 1 and 3, the tubular portion 42 is formed in a bottomed tubular shape having a horizontally long and upward opening in the left-right direction and a bottom wall 46 at the lower end portion of the tubular portion 42. The bottom wall 46 and the electric wire side connection portion 23 of the terminal 20 face upward from the upper end opening. The bottom wall 46 has an oval shape that is horizontally long in the left-right direction, and three covering portions 41 arranged in the left-right direction are arranged in the center of the bottom wall 46 so as to be integrated with the bottom wall 46.

嵌合部４３は、図１、図２、図４および図５に示すように、筒状部４２の下面から下方に延びた形態とされており、嵌合部４３の外周には、シールリングＲが嵌着されている。嵌合部４３の内部には、３つの端子２０における端子本体２１の下半分が一括して埋設されており、嵌合部４３の下方には、端子２０の機器側接続部２４が嵌合部４３の下面から下方に突出した状態で配されている。 As shown in FIGS. 1, 2, 4, and 5, the fitting portion 43 has a form extending downward from the lower surface of the tubular portion 42, and a seal ring is formed on the outer periphery of the fitting portion 43. R is fitted. Inside the fitting portion 43, the lower halves of the terminal bodies 21 of the three terminals 20 are collectively embedded, and below the fitting portion 43, the device-side connecting portion 24 of the terminal 20 is a fitting portion. It is arranged so as to project downward from the lower surface of the 43.

機器側接続部２４の後方には、嵌合部４３の下端部に連なるようにして端子毎に設けられた機器側ナット収容部４９が左右に連結して設けられている。機器側ナット収容部４９は、下方に開口しており、機器側ナット収容部４９には、下端開口からナットＮが圧入状態で収容されるようになっている。 Behind the device-side connection portion 24, a device-side nut accommodating portion 49 provided for each terminal so as to be connected to the lower end portion of the fitting portion 43 is provided to be connected to the left and right. The device-side nut accommodating portion 49 is opened downward, and the nut N is accommodated in the device-side nut accommodating portion 49 in a press-fitted state from the lower end opening.

さて、端子台１０は、２回に分けて樹脂成形を行うことで構成されている。詳しくは、端子台１０は、まず、端子２０とモールド部６２とからなる１次成形品６１を構成し、この１次成形品６１を左右方向に３つ並べて１次成形品群６０とする。そして、１次成形品群６０を中子として成形金型内にセットし、２次成形部７０を成形することにより形成されている。すなわち、ハウジング４０は、１次成形品６１のモールド部６２と２次成形部７０とが一体となることで構成されている。 By the way, the terminal block 10 is configured by performing resin molding in two steps. Specifically, the terminal block 10 first constitutes a primary molded product 61 composed of a terminal 20 and a mold portion 62, and three primary molded products 61 are arranged in the left-right direction to form a primary molded product group 60. Then, the primary molded product group 60 is set as a core in the molding die, and the secondary molded portion 70 is molded. That is, the housing 40 is configured such that the mold portion 62 of the primary molded product 61 and the secondary molded portion 70 are integrated.

以下に１次成形品６１および２次成形部７０について説明する。
１次成形品６１における端子２０は、上述したように、肉厚の金属板材をプレス加工によって打ち抜いて、曲げ加工を施すことによって形成された曲げ部２２を有する端子２０である。 The primary molded product 61 and the secondary molded portion 70 will be described below.
As described above, the terminal 20 in the primary molded product 61 is a terminal 20 having a bent portion 22 formed by punching a thick metal plate material by press working and bending it.

ところで、端子２０において、肉厚の金属板材に曲げ加工を施して曲げ部２２を形成すると、曲げ部２２の板厚方向の沿って延びる側部２２Ａの外周縁部は、曲げ部２２の外側の外曲面３１の延びに伴って左右方向内側に向けて減肉された状態の減肉部３４となる。また、曲げ部２２の側部２２Ａにおける内周縁部には、曲げ部２２の内曲面３０に撓みが生じて外側に膨出する余肉が生じてしまう。つまり、曲げ部２２の側部２２Ａは、外側から内側に向かうほど幅広となってしまう。
そこで、曲げ部２２の側部２２Ａに生じた余肉を平面状に加工するプレス加工などを施すことにより、曲げ部２２の側部２２Ａにおける内周縁部には、図１８の模式図に示すように、平面状をなす平面部３２が形成される。また、平面部３２は、図１５に示すように、接続部側平面部２７および本体側平面部２５と面一状に形成されている。つまり、曲げ部２２の側部２２Ａは、その内周縁部に平面状の平面部３２を有し、その外周縁部に平面部３２よりも薄肉で幅狭な形態の減肉部３４を有する構成となっている。なお、端子２０のその他の構成については、重複するため、説明を省略する。 By the way, when the bent portion 22 is formed by bending a thick metal plate material at the terminal 20, the outer peripheral edge portion of the side portion 22A extending along the plate thickness direction of the bent portion 22 is outside the bent portion 22. The wall thinning portion 34 is in a state of being thinned inward in the left-right direction as the outer curved surface 31 extends. Further, on the inner peripheral edge portion of the side portion 22A of the bent portion 22, the inner curved surface 30 of the bent portion 22 is bent and a surplus wall portion that bulges outward is generated. That is, the side portion 22A of the bent portion 22 becomes wider from the outside to the inside.

The bent portion covering portion 64 is formed so as to be continuous with the portions, and is configured by exposing both side portions 22A of the bent portion 22.

本体覆い部６５は、図１０から図１２に示すように、曲げ部覆い部６４の下端部に連なるようにして、端子本体２１の前面２１Ａにおける上端部および本体側平面部２５の上端部２５Ａを除く端子本体２１の上端寄りの部分を全周に亘って覆うように形成されている。したがって、本体覆い部６５は、本体側平面部２５の上端部２５Ａを露出させて構成されている。 As shown in FIGS. 10 to 12, the main body covering portion 65 is connected to the lower end portion of the bent portion covering portion 64 so that the upper end portion of the front surface 21A of the terminal main body 21 and the upper end portion 25A of the main body side flat portion 25 are connected to each other. It is formed so as to cover the portion of the terminal body 21 to be removed near the upper end over the entire circumference. Therefore, the main body covering portion 65 is configured by exposing the upper end portion 25A of the main body side flat portion 25.

すなわち、曲げ部２２の左右両側の側部２２Ａと、曲げ部２２および接続部覆い部６３と隣り合う接続部側平面部２７の後端部２７Ａと、曲げ部２２および本体覆い部６５と隣り合う本体側平面部２５の上端部２５Ａとは、図８、図１１、図１５および図１７に示すように、いずれもモールド部６２から露出しており、接続部側平面部２７の後端部２７Ａと、曲げ部２２の平面部３２と、端子本体２１の本体側平面部２５の上端部２５Ａとは、端子２０の側面に沿うように面一状に連なった樹脂食い切り面３３とされている。 That is, the side portions 22A on both the left and right sides of the bent portion 22, the rear end portion 27A of the connecting portion side flat portion 27 adjacent to the bent portion 22 and the connecting portion covering portion 63, and the bent portion 22 and the main body covering portion 65 are adjacent to each other. As shown in FIGS. 8, 11, 15 and 17, the upper end portion 25A of the main body side flat portion 25 is exposed from the mold portion 62, and the rear end portion 27A of the connection portion side flat portion 27 is exposed. The flat surface portion 32 of the bent portion 22 and the upper end portion 25A of the flat surface portion 25 on the main body side of the terminal main body 21 are formed as a resin cutting surface 33 which is flushed along the side surface of the terminal 20.

ナット収容部６６は、ハウジング４０のナット収容部４５を構成するものであって、図１２および図１３に示すように、接続部覆い部６３の下端部、曲げ部覆い部６４の後端部および下端部、本体覆い部６５の後端部に連なるようにして形成されており、図１１に示すように、側面視略矩形状をなす箱形状に構成されている。なお、ナット収容部６６の構造に関しては、上述のナット収容部４５の構造と重複するため説明を省略する。また、ナット収容部６６内には、１次成形品６１が完成したところで、ナットＮを挿入し、ナットＮを収容した状態の１次成形品６１を中子として２次成形部７０を成形する。 The nut accommodating portion 66 constitutes the nut accommodating portion 45 of the housing 40, and as shown in FIGS. 12 and 13, the lower end portion of the connecting portion covering portion 63, the rear end portion of the bent portion covering portion 64, and the nut accommodating portion 66. It is formed so as to be connected to the lower end portion and the rear end portion of the main body covering portion 65, and is formed in a box shape having a substantially rectangular shape in side view as shown in FIG. The structure of the nut accommodating portion 66 will not be described because it overlaps with the structure of the nut accommodating portion 45 described above. Further, when the primary molded product 61 is completed, the nut N is inserted into the nut accommodating portion 66, and the secondary molded portion 70 is formed by using the primary molded product 61 in the state of accommodating the nut N as a core. ..

２次成形部７０は、大まかには、ハウジング４０における筒状部４２、嵌合部４３および機器側ナット収容部４９を構成するものであって、筒状部４２の底壁４６が１次成形品６１のモールド部６２における下端部に連なって成形されることで、１次成形品６１と２次成形部７０とが一体に固定され、端子台１０が構成されるようになっている。 The secondary forming portion 70 roughly constitutes the tubular portion 42, the fitting portion 43, and the device side nut accommodating portion 49 in the housing 40, and the bottom wall 46 of the tubular portion 42 is primarily formed. The primary molded product 61 and the secondary molded portion 70 are integrally fixed by being integrally molded with the lower end portion of the molded portion 62 of the product 61, so that the terminal block 10 is configured.

本実施形態は、以上のような構成であって、続いて、端子台１０の組み立てを行う際の手順を簡単に説明すると共に、その作用および効果について説明する。
端子台１０の組み立てでは、最初に１次成形品６１を複数成形する。
１次成形品６１は、まず肉厚の金属板材をプレス加工打ち抜いて曲げ加工を施すことによって端子２０を形成し、端子２０を成形金型（図示せず）内にセットする。 This embodiment has the above-described configuration, and subsequently, a procedure for assembling the terminal block 10 will be briefly described, and its operation and effect will be described.
In assembling the terminal block 10, a plurality of primary molded products 61 are first molded.
In the primary molded product 61, a terminal 20 is first formed by punching and bending a thick metal plate material, and the terminal 20 is set in a molding die (not shown).

ここで、端子２０が成形金型内にセットされると、端子２０の端子本体２１においては、シール被着部２６のやや上方の位置が成形金型によって全周に亘って押圧されると共に、本体側平面部２５の上端部２５Ａおよび端子本体２１の前面２１Ａにおける上端部が成形金型によって押圧された状態となる。また、端子２０の電線側接続部２３においては、接続部側平面部２７の後端部２７Ａおよび接続部側平面部２７の上半分が成形金型によって押圧され、曲げ部２２においては、左右方向両側の側部２２Ａにおける平面部３２が押圧された状態となる。すなわち、端子２０の両側面においては樹脂食い切り面３３が成形金型によって押圧された状態となる。 Here, when the terminal 20 is set in the molding die, in the terminal body 21 of the terminal 20, the position slightly above the seal attachment portion 26 is pressed by the molding die over the entire circumference. The upper end portion 25A of the main body side flat portion 25 and the upper end portion of the front surface 21A of the terminal main body 21 are pressed by the molding die. Further, in the electric wire side connecting portion 23 of the terminal 20, the rear end portion 27A of the connecting portion side flat portion 27 and the upper half of the connecting portion side flat portion 27 are pressed by the molding die, and in the bending portion 22, the left-right direction. The flat surface portions 32 on the side portions 22A on both sides are in a pressed state. That is, on both side surfaces of the terminal 20, the resin cutting surface 33 is pressed by the molding die.

この状態で、成形金型内に成形樹脂が射出されると、端子２０と成形金型とが接触した部分において樹脂が食い切られてモールド部６２が成形され、端子２０とモールド部６２とが一体に固定された１次成形品６１が完成する。 In this state, when the molding resin is injected into the molding die, the resin is cut off at the portion where the terminal 20 and the molding die are in contact with each other to form the mold portion 62, and the terminal 20 and the mold portion 62 are formed. The integrally fixed primary molded product 61 is completed.

ところで、例えば、肉厚の金属板材をプレス加工することで曲げ部を有する端子を形成するものの、曲げ部の側面に平面部を形成しない場合には、曲げ部の側面には、プレス加工に伴って生じた余肉が残ったままとなってしまう。すると、端子を成形金型内にセットする際に、余肉が成形金型と干渉することで、端子を成形金型内にセットすることができなくなってしまう。 By the way, for example, when a terminal having a bent portion is formed by pressing a thick metal plate material, but a flat portion is not formed on the side surface of the bent portion, the side surface of the bent portion is subjected to the press working. The resulting surplus meat remains. Then, when the terminal is set in the molding die, the residual thickness interferes with the molding die, so that the terminal cannot be set in the molding die.

仮に、端子を成形金型内にセットできたとしても、曲げ部の側面を成形金型によって押圧した際に、曲げ部の側面と成形金型との間に隙間が形成される虞があり、隙間が形成された場合には、隙間から樹脂漏れが生じることで、曲げ部の外曲面、さらには電線側接続部の接続面に樹脂が付着してしまう。 Even if the terminals can be set in the molding die, when the side surface of the bent portion is pressed by the molding die, a gap may be formed between the side surface of the bent portion and the molding die. When a gap is formed, resin leaks from the gap, so that the resin adheres to the outer curved surface of the bent portion and further to the connecting surface of the electric wire side connecting portion.

ところが、本実施形態によると、端子２０を成形金型内にセットすると、端子２０の側面においては樹脂食い切り面３３が成形金型によって押圧された状態となるから、各覆い部６３，６４，６５を成形する成形樹脂が樹脂食い切り面３３において確実に食い切られ、平面部３２を境にモールド部６２とは反対側に配された減肉部３４や電線側接続部２３の接続面２８に成形樹脂が付着すること無く、モールド部６２が成形される。
そして、モールド部６２が冷却されて硬化することで端子２０とモールド部６２とが一体に固定された１次成形品６１が完成する。 However, according to the present embodiment, when the terminal 20 is set in the molding die, the resin cutting surface 33 is pressed by the molding die on the side surface of the terminal 20, so that the covering portions 63, 64, 65 The molding resin for molding is surely cut off on the resin cutting surface 33, and is molded on the connecting surface 28 of the wall thinning portion 34 and the electric wire side connecting portion 23 arranged on the side opposite to the molding portion 62 with the flat surface portion 32 as a boundary. The mold portion 62 is molded without the resin adhering to it.
Then, the mold portion 62 is cooled and cured to complete the primary molded product 61 in which the terminal 20 and the mold portion 62 are integrally fixed.

すなわち、本実施形態によると、プレス加工によって歪みが生じた曲げ部２２の側部２２Ａにおける内周縁部に平面部３２を設け、平面部３２と成形金型、本体側平面部２５の上端部２５Ａと成形金型、接続部側平面部２７の後端部２７Ａと成形金型との間、つまり、樹脂食い切り面３３において成形樹脂を食い切ることができるから、曲げ部２２の側部２２Ａを通して成形樹脂が曲げ部２２の減肉部３４や外曲面３１、ひいては電線側接続部２３の接続面２８に付着することを防ぐことができる。これにより、電線側接続部２３と相手方端子との接続信頼性が低下することを防ぐことができる。 That is, according to the present embodiment, a flat surface portion 32 is provided on the inner peripheral edge portion of the side portion 22A of the bent portion 22 that has been distorted by press processing, and the flat surface portion 32, the molding die, and the upper end portion 25A of the main body side flat surface portion 25 are provided. And the molding die, between the rear end portion 27A of the connecting portion side flat portion 27 and the molding die, that is, the molding resin can be cut off at the resin cutting surface 33, so that the molding resin can be cut through the side portion 22A of the bending portion 22. It is possible to prevent the resin from adhering to the thinned portion 34 of the bent portion 22, the outer curved surface 31, and the connection surface 28 of the electric wire side connecting portion 23. As a result, it is possible to prevent the connection reliability between the electric wire side connecting portion 23 and the mating terminal from being lowered.

このようにして、１次成形品６１を複数完成させたところで、１次成形品６１を左右方向に３つ並べて１次成形品群６０とし、この１次成形品群６０を中子として２次成形部７０を成形することで、端子台１０を完成させることができる。 When a plurality of primary molded products 61 are completed in this way, three primary molded products 61 are arranged in the left-right direction to form a primary molded product group 60, and the primary molded product group 60 is used as a core for secondary molding. The terminal block 10 can be completed by molding the molded portion 70.

ところで、曲げ部２２の側部２２Ａにおいて樹脂を食い切る場合、例えば、曲げ部の側面における内周縁部だけでなく、曲げ部の側面全体もしくは曲げ部の側面における外周縁部に平面部を設けて成形樹脂を食い切る方法も考えられる。
しかしながら、肉厚の金属板材を折り曲げると、曲げ部の側面における外周縁部は、曲げ部の外側の外曲面の延びに伴って左右方向内側に向けて減肉された状態となり、曲げ部の側面における内周縁部は、曲げ部の内側の内曲面に撓みが生じて外側に膨出する余肉が生じてしまう。 By the way, when the resin is cut off at the side portion 22A of the bent portion 22, for example, not only the inner peripheral edge portion on the side surface of the bent portion but also the entire side surface portion of the bent portion or the outer peripheral edge portion on the side surface of the bent portion is provided with a flat surface portion. A method of cutting off the molding resin is also conceivable.
However, when the thick metal plate is bent, the outer peripheral edge portion on the side surface of the bent portion is in a state of being thinned inward in the left-right direction as the outer curved surface on the outside of the bent portion extends, and the side surface of the bent portion is bent. In the inner peripheral edge portion in the above, the inner curved surface inside the bent portion is bent, and a surplus thickness that bulges outward is generated.

したがって、曲げ部の側面全体や側面の外周縁部において曲げ部の幅寸法を管理しようとすると、各端子の曲げ部の幅寸法においてばらつきが生じてしまう。そして、このような端子を成形金型内にセットする場合には、端子毎に成形金型の配置を調整して、曲げ部の側面に成形金型を接触させる必要があるため、端子台の組み立て作業の作業効率が低下してしまう。 Therefore, if an attempt is made to control the width dimension of the bent portion on the entire side surface of the bent portion or the outer peripheral edge portion of the side surface, the width dimension of the bent portion of each terminal will vary. When setting such a terminal in the molding die, it is necessary to adjust the arrangement of the molding die for each terminal so that the molding die is brought into contact with the side surface of the bent portion. The work efficiency of the assembly work is reduced.

ところが、本実施形態によると、曲げ部２２の側部２２Ａにおいて膨出した余肉を平面状に加工して、電線側接続部２３の接続部側平面部２７および端子本体２１の本体側平面部２５と面一となるように平面部３２を形成している。つまり、曲げ部２２の左右方向の幅寸法を電線側接続部２３および端子本体２１の左右方向の幅寸法に揃えているから、端子２０毎に成形金型の配置を調整することなく、１次成形品６１を成形金型内にセットすることができる。これにより、端子台１０の組み立て作業の作業効率が低下することを防ぐことができるようになっている。 However, according to the present embodiment, the bulging surplus on the side portion 22A of the bent portion 22 is processed into a flat surface so that the connecting portion side flat portion 27 of the electric wire side connecting portion 23 and the main body side flat portion of the terminal body 21 are formed. The flat surface portion 32 is formed so as to be flush with 25. That is, since the width dimension of the bent portion 22 in the left-right direction is aligned with the width dimension of the electric wire side connection portion 23 and the terminal body 21 in the left-right direction, the primary arrangement of the molding die is not adjusted for each terminal 20. The molded product 61 can be set in the molding mold. This makes it possible to prevent the work efficiency of the terminal block 10 assembly work from being lowered.

以上のように、本実施形態によると、１次成形品６１を成形する際に、曲げ部２２が略直角に折り曲げられ、曲げ部２２の側部２２Ａにおける内周縁部に余肉が生じたとしても、プレス加工によって歪みが生じた曲げ部２２の側部２２Ａに平面部３２を形成して端子２０の側面に樹脂食い切り面３３を設け、樹脂食い切り面３３と成形金型との間において成形樹脂を食い切ることができるから、曲げ部２２の側部２２Ａを通して成形樹脂が曲げ部２２の外曲面３１や電線側接続部２３の接続面２８に付着することを防ぐことができる。すなわち、電線側接続部２３の接続面２８に樹脂が付着することに起因して、電線側接続部２３と相手方端子との接続信頼性が低下することを防ぐことができる。 As described above, according to the present embodiment, when the primary molded product 61 is molded, the bent portion 22 is bent at a substantially right angle, and a surplus thickness is generated on the inner peripheral edge portion of the side portion 22A of the bent portion 22. In addition, a flat surface portion 32 is formed on the side portion 22A of the bent portion 22 that has been distorted by the pressing process, a resin cutting surface 33 is provided on the side surface of the terminal 20, and a molding resin is provided between the resin cutting surface 33 and the molding die. It is possible to prevent the molding resin from adhering to the outer curved surface 31 of the bent portion 22 and the connecting surface 28 of the electric wire side connecting portion 23 through the side portion 22A of the bent portion 22. That is, it is possible to prevent the connection reliability between the electric wire side connecting portion 23 and the mating terminal from being lowered due to the resin adhering to the connecting surface 28 of the electric wire side connecting portion 23.

すなわち、本実施形態によると、曲げ部２２の側面における内周縁部にのみ平面状の加工を施すだけで、１次成形品６１において樹脂漏れを防止しつつ、１次成形品６１を成形金型内にセット可能にすることができるから、金属板材の厚みが増すことでプレス加工した部分に歪みが生じる場合には、非常に有効である。 That is, according to the present embodiment, only the inner peripheral edge portion on the side surface of the bent portion 22 is subjected to flat processing, and the primary molded product 61 is molded into a molding die while preventing resin leakage in the primary molded product 61. Since it can be set inside, it is very effective when the pressed portion is distorted due to an increase in the thickness of the metal plate material.

また、本実施形態によると、曲げ部２２の側部２２Ａの内周縁部に平面部３２を形成し、曲げ部２２の左右方向の幅寸法を電線側接続部２３および端子本体２１の左右方向の幅寸法に揃えているから、例えば、曲げ部の側面全体や曲げ部の側面における外周縁部を基準に曲げ部の幅寸法を設定する場合に比べて、端子２０全体の幅寸法の寸法管理を容易にすることができる。これにより、端子２０毎に成形金型の配置を調整することなく、１次成形品６１を成形金型内にセットすることができ、端子台１０の組み立て作業の作業効率が低下することを防ぐことができる。 Further, according to the present embodiment, a flat surface portion 32 is formed on the inner peripheral edge portion of the side portion 22A of the bent portion 22, and the width dimension of the bent portion 22 in the left-right direction is set in the left-right direction of the electric wire side connecting portion 23 and the terminal body 21. Since the width dimensions are aligned, for example, the width dimension of the entire terminal 20 can be controlled as compared with the case where the width dimension of the bent portion is set based on the entire side surface of the bent portion or the outer peripheral edge portion on the side surface of the bent portion. Can be facilitated. As a result, the primary molded product 61 can be set in the molding die without adjusting the arrangement of the molding die for each terminal 20, and it is possible to prevent the work efficiency of the assembly work of the terminal block 10 from being lowered. be able to.
