Description

本発明は、コネクタの製造方法に関する。   The present invention relates to a method for manufacturing a connector.

例えば、車両の車体に取り付けられてワイヤハーネス回路の一部を車体に接地するためのコネクタとして、特許文献1に記載のものが知られている。   For example, a connector described in Patent Document 1 is known as a connector that is attached to a vehicle body and grounds a part of a wire harness circuit to the vehicle body.

この種のコネクタは、図9に示すように端子金具120をコネクタハウジング内にインサート成型して成型したコネクタハウジング140から構成され、端子金具120が有する第一、第二のL字状曲げ部121,122がコネクタハウジング140の樹脂内でクランク状の構造を成し、第一のL字状曲げ部121に近い末端部であるタブ部123が相手方コネクタ(図示せず)の端子金具と接続され、第二のL字状曲げ部122に近い末端部である設置部124が取付け部位(図示せず)に固定される構造となっている。   As shown in FIG. 9, this type of connector is composed of a connector housing 140 in which a terminal fitting 120 is insert-molded into a connector housing, and the first and second L-shaped bent portions 121 of the terminal fitting 120 are provided. , 122 form a crank-like structure in the resin of the connector housing 140, and the tab portion 123, which is the end portion close to the first L-shaped bent portion 121, is connected to the terminal fitting of the mating connector (not shown). The installation portion 124, which is the end portion close to the second L-shaped bent portion 122, is fixed to an attachment site (not shown).

特開2006−114245号公報JP 2006-114245 A

この種のコネクタでは相手方コネクタを抜差しするときの嵌合力は、端子金具120の取付け部位に近い第二のL字曲げ部122に集中して、第二のL字曲げ部122が大きく撓むことがある。ところが、従来から用いられている構造では、第二のL字曲げ部122を樹脂部141が内包しているため、樹脂部141にクラックを生ずることが懸念されている。   In this type of connector, the fitting force when inserting / removing the mating connector is concentrated on the second L-shaped bent portion 122 close to the attachment portion of the terminal fitting 120, and the second L-shaped bent portion 122 is greatly bent. There is. However, in the structure used conventionally, since the resin part 141 includes the second L-shaped bent part 122, there is a concern that the resin part 141 may crack.

また、当該コネクタのコネクタハウジング140を成型するには開口縁を上方向に配置した下型150に端子金具120をセットし、上方向から開口縁を下方向にした上型160を覆い被せることによって成型金型を構成し、インサート成型する。   Further, in order to mold the connector housing 140 of the connector, the terminal fitting 120 is set on the lower mold 150 with the opening edge arranged upward, and the upper mold 160 with the opening edge downward is covered from above. Configure the mold and insert mold.

コネクタハウジング140の構造上、成型金型内に端子金具120をセットするには下型150に形成されているタブ部挿入孔151に端子金具120のタブ部123を挿入し、上方向に突き出した端子金具120の設置部124を上型160の設置部挿入孔161に挿入しつつ、上型160を上方から設置するが、端子金具120をそれぞれの挿入孔151,161に挿入する為、それぞれの挿入孔には僅かなクリアランスを持たせる必要がある。その為、上記に示した金型を用いて成型されたコネクタハウジング140内の端子金具120は成型金型の中に樹脂を射出する際に挿入孔内で僅かに動き得る不確定な状態となり、完成したコネクタハウジング140内において端子金具120の位置がバラツくといった問題が発生する。   Due to the structure of the connector housing 140, in order to set the terminal fitting 120 in the molding die, the tab portion 123 of the terminal fitting 120 is inserted into the tab portion insertion hole 151 formed in the lower die 150 and protrudes upward. While the installation part 124 of the terminal fitting 120 is inserted into the installation part insertion hole 161 of the upper mold 160, the upper mold 160 is installed from above, but the terminal fitting 120 is inserted into the respective insertion holes 151, 161. The insertion hole needs to have a slight clearance. Therefore, the terminal fitting 120 in the connector housing 140 molded using the mold shown above becomes an indeterminate state that can move slightly in the insertion hole when the resin is injected into the mold. There arises a problem that the position of the terminal fitting 120 varies in the completed connector housing 140.

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、端子金具を被覆する樹脂部の破損を防ぎ、端子金具の位置にバラツキが生じにくいコネクタを製造する方法を提供することを目的とする。   The present invention has been completed based on the above circumstances, and provides a method for manufacturing a connector that prevents damage to the resin portion covering the terminal metal fitting and is less likely to cause variations in the position of the terminal metal fitting. Objective.

上記の目的を達するための手段として本発明は、端子金具を成型金型内にセットしてインサート成型することによりコネクタハウジングを端子金具と一体化してなるコネクタの製造方法であって、前記端子金具が、前記コネクタを取付け部位に固定するための固定片部と、相手方コネクタの嵌合方向に沿って延びるタブ部と、第一及び第二のL字曲げ部を介して前記固定片部と前記タブ部とが段違いの平行状となるように連結する連結部とを備えたクランク状のものにおいて、前記成型金型を、前記タブ部の延長方向に沿って型開きする第一及び第二の金型から構成すると共に、それらの第一及び第二の金型間に前記コネクタハウジングを成型するためのキャビティが形成されるようになし、前記第一の金型には前記タブ部を挿入するためのタブ挿入孔を形成し、前記第一及び第二の金型の合わせ面には、型締め時に前記端子金具の前記連結部を挟み込んで固定する金具押さえ部を形成し、前記タブ部に近い前記L字曲げ部は前記キャビティ内に位置させ、前記前記固定片部に近い前記L字曲げ部は前記キャビティの外に位置させた状態となし、かつ、第二の金型には前記キャビティ内の前記タブ部が前記タブ挿入孔内に押し込まれる方向に樹脂を射出するゲートを配置して前記インサート成型を行うところに特徴を有する。   As a means for achieving the above object, the present invention provides a method for manufacturing a connector in which a connector housing is integrated with a terminal fitting by setting the terminal fitting in a molding die and insert molding, A fixing piece for fixing the connector to the attachment site, a tab extending along the fitting direction of the mating connector, the fixing piece through the first and second L-shaped bent portions, and the In the crank-shaped thing provided with the connection part which connects so that a tab part may become parallel in a step, the first and second which open the mold along the extension direction of the tab part A cavity for molding the connector housing is formed between the first and second molds, and the tab portion is inserted into the first mold. for Forming a bracket insertion hole, and on the mating surfaces of the first and second molds, forming a metal fitting pressing portion that sandwiches and fixes the connecting portion of the terminal metal fitting when clamping, and close to the tab portion The L-shaped bent portion is positioned in the cavity, the L-shaped bent portion close to the fixed piece portion is positioned outside the cavity, and the second mold has the inside of the cavity. The insert molding is performed by arranging a gate for injecting resin in a direction in which the tab portion is pushed into the tab insertion hole.

このような構成によると、成型金型内で端子金具をタブ挿入孔と金具押さえ部との二箇所において固定させることができる。しかも、金具押さえ部では金型の型締め時に端子金具を挟み込んで固定するから、端子金具を孔に挿入する固定方法と異なり、がたつきなく確実に端子金具を成型金型に固定することができ、端子金具の位置精度が高くなる。更には、第二の金型には、端子金具をタブ挿入孔内に押し込む方向に樹脂を射出するゲートを配置したから、樹脂の射出時に端子金具が第一の金型に強く押し付けられ、その面からも端子金具が固定されて位置精度が高くなる。   According to such a structure, a terminal metal fitting can be fixed in two places, a tab insertion hole and a metal fitting pressing part, in a molding die. Moreover, since the metal fitting holding part clamps and fixes the terminal fitting when the mold is clamped, unlike the fixing method in which the terminal fitting is inserted into the hole, the terminal fitting can be securely fixed to the molding die without rattling. This increases the position accuracy of the terminal fitting. Furthermore, since the gate for injecting the resin in the direction in which the terminal metal fitting is pushed into the tab insertion hole is arranged in the second mold, the terminal metal fitting is strongly pressed against the first metal mold when the resin is injected. The terminal fitting is also fixed from the surface, and the positional accuracy is increased.

また、当該コネクタは固定片部に近いL字曲げ部がコネクタハウジングの外部に形成されているため、大きな嵌合力によって相手方コネクタを抜差しした場合に、そのL字曲げ部において屈曲度合いが変化するように弾性変形しても、その影響は樹脂部に及ばないから、樹脂部の破損を極力防止することができる。   Also, since the connector has an L-shaped bent portion close to the fixed piece portion formed outside the connector housing, when the mating connector is inserted and removed by a large fitting force, the bending degree changes in the L-shaped bent portion. Even if it is elastically deformed, the influence does not reach the resin part, so that damage to the resin part can be prevented as much as possible.

本発明の実施の態様として、以下の構成が望ましい。   The following configuration is desirable as an embodiment of the present invention.

前記端子金具の前記タブ部には、中央部よりややL字曲げ部に近い位置からL字曲げ部に向かって徐々に肉厚が厚くなる傾斜面が形成され、前記第1の金型には前記タブ挿入孔に挿入された前記端子金具の前記傾斜面を受けて前記端子金具を固定するテーパ面が形成されることが望ましい。   The tab portion of the terminal fitting is formed with an inclined surface that gradually increases in thickness from the position slightly closer to the L-shaped bent portion than the center portion toward the L-shaped bent portion. It is desirable that a tapered surface that receives the inclined surface of the terminal fitting inserted into the tab insertion hole and fixes the terminal fitting is formed.

このような構成によると、樹脂の射出時に端子金具に作用する力は、端子金具の傾斜部が第一の金型のテーパ面に押し付けられることによって受けられる。この結果、タブ部の先端がタブ挿入孔の奥端に押し当てられて先端の変形を引き起こすことがなく、また、斜面同士の押し当てによって端子金具が横に押し付けられてタブ挿入孔の側壁に密着することから、端子金具の位置精度が一層高くなる。   According to such a structure, the force which acts on a terminal metal fitting at the time of injection | pouring of resin is received when the inclined part of a terminal metal fitting is pressed on the taper surface of a 1st metal mold | die. As a result, the tip of the tab portion is not pressed against the back end of the tab insertion hole, and the tip is not deformed, and the terminal fitting is pressed sideways by pressing the inclined surfaces to the side wall of the tab insertion hole. Because of the close contact, the positional accuracy of the terminal fitting is further increased.

本発明によれば、端子金具を被覆する樹脂部の破損を防ぎ、端子金具の位置にバラツキが生じにくい成型金型によって端子金具がインサート成型されたコネクタを製造することができる。   ADVANTAGE OF THE INVENTION According to this invention, the connector by which the terminal metal fitting was insert-molded with the shaping | molding die which prevents the damage of the resin part which coat | covers a terminal metal fitting, and the position of a terminal metal fitting does not produce easily can be manufactured.

タブ部21には周囲四辺がテーパ状になった先細部21Aが形成されており、固定片部22には中心からやや末端よりの位置に固定ボルト51を通すボルト孔22Aとその四隅にボルト孔22Aよりも小さめの貫通孔22Bとが形成されている。   The tab portion 21 is formed with a tapered detail 21A having four tapered sides. The fixing piece portion 22 has a bolt hole 22A through which the fixing bolt 51 is passed slightly from the center and a bolt hole at its four corners. A through hole 22B smaller than 22A is formed.

タブ部21と固定片部22とは平行した状態にあり、タブ部21と連結部23とを第1のL字曲げ部に相当する第一L字曲げ部24、固定片部22と連結部23とを第2のL字曲げ部に相当する第二L字曲げ部25により連結させることにより端子金具全体の外観がクランク状を成すような構造になっている。   The tab portion 21 and the fixed piece portion 22 are in a parallel state, and the tab portion 21 and the connecting portion 23 are connected to the first L-shaped bent portion 24 corresponding to the first L-shaped bent portion, the fixed piece portion 22 and the connecting portion. 23 is connected by a second L-shaped bent portion 25 corresponding to the second L-shaped bent portion, so that the entire appearance of the terminal fitting has a crank shape.

コネクタハウジング40は、図1及び図2に示すように、ほぼ円筒状をなす円筒部42の終端に奥壁部41を有する有底円筒状をなし、その奥壁部41の外形は正面視矩形状をなす。   As shown in FIGS. 1 and 2, the connector housing 40 has a bottomed cylindrical shape having a back wall portion 41 at the end of a cylindrical portion 42 having a substantially cylindrical shape, and the outer shape of the back wall portion 41 is rectangular in front view. Make a shape.

円筒部42の中央位置より前方部分には嵌合時に雌側コネクタを収容するフード部44が形成されている。フード部44の上方には、前後に延びる係合片案内溝42Aが形成され、図示しない雌側コネクタとの嵌合時に、その雌側コネクタに設けられた係合片が進入できるようになっている。その係合片は、両コネクタが正規の嵌合位置に至ると、係合片案内溝42Aの後方部分である収容部43の上方に位置している天井壁43Aの係合爪43Bと係合することで両コネクタの嵌合状態を保持する。   A hood portion 44 that accommodates the female connector at the time of fitting is formed in the front portion from the central position of the cylindrical portion 42. An engaging piece guide groove 42A extending in the front-rear direction is formed above the hood portion 44 so that the engaging piece provided on the female connector can enter when fitted to a female connector (not shown). Yes. When both connectors reach the proper fitting position, the engaging piece engages with the engaging claw 43B of the ceiling wall 43A located above the accommodating portion 43, which is the rear portion of the engaging piece guide groove 42A. By doing so, the fitting state of both connectors is maintained.

円筒部42の外周壁の斜め下方には開口縁より奥壁部41まで延びた案内リブ42Bが形成されている。コネクタハウジング40の円筒部42を収容する雌側コネクタ(図示せず)に嵌合する時には、案内リブ42Bがそれに対応するリブ溝に嵌合して摺動することにより雄側コネクタが雌側コネクタの所定の位置に案内される。   A guide rib 42 </ b> B extending from the opening edge to the back wall portion 41 is formed obliquely below the outer peripheral wall of the cylindrical portion 42. When fitting into a female connector (not shown) that accommodates the cylindrical portion 42 of the connector housing 40, the guide rib 42B is fitted into the corresponding rib groove and slid to cause the male connector to become a female connector. To a predetermined position.

円筒部42のフード部44には奥壁のほぼ中央に奥壁部41まで陥没させた凹部45が形成されている。凹部45は矩形の開口縁から底面部に向かって窄んだすり鉢状に構成されている。   The hood portion 44 of the cylindrical portion 42 is formed with a concave portion 45 that is recessed to the back wall portion 41 at substantially the center of the back wall. The recess 45 is formed in a mortar shape that is narrowed from the rectangular opening edge toward the bottom surface.

凹部45にはその開口縁部分から底面部に向かって形成された二段の段差部47と底面部において中心に向かって隆起した隆起部48とが設けられ、隆起部48の中心からは端子金具20のタブ部21が突出しフード部44の中央部まで嵌合方向に沿って延びている。   The recessed portion 45 is provided with a two-stepped portion 47 formed from the opening edge portion toward the bottom surface portion and a raised portion 48 that protrudes toward the center at the bottom surface portion. 20 tab portions 21 protrude and extend in the fitting direction to the center portion of the hood portion 44.

凹部45にはタブ部21と凹部45の内壁面45Aとに密着するポッティング材49を樹脂材の注入量の目安となる段差部47まで充填することによって防水を図っている。   The recessed portion 45 is waterproofed by filling a potting material 49 that is in close contact with the tab portion 21 and the inner wall surface 45A of the recessed portion 45 up to a stepped portion 47 that serves as a guide for the amount of resin material injected.

コネクタハウジング40にはタブ部21の中央よりやや後方部に位置する凹部45とコネクタハウジング40との境界から連結部23の中央よりやや第二L字曲げ部側までが樹脂内に埋め込まれ、第二L字曲げ部25はコネクタハウジング40の外側に配置されている。   The connector housing 40 is embedded in the resin from the boundary between the concave portion 45 located slightly rearward from the center of the tab portion 21 and the connector housing 40 to the second L-shaped bent portion side from the center of the connecting portion 23. The two L-shaped bent portions 25 are disposed outside the connector housing 40.

第二L字曲げ部25より後方向に延びた固定片部22は固定ボルト51をボルト孔22Aに貫通させ取付け部位50に螺合させることによって固定させるようになっている。   The fixing piece portion 22 extending rearward from the second L-shaped bent portion 25 is fixed by passing a fixing bolt 51 through the bolt hole 22A and screwing it into the attachment portion 50.

さて、端子金具20の連結部23には取付け部位50からコネクタハウジング40を離して支持しコネクタハウジング40より取付け部位50に向かって突出した突出部26が構成され、端子金具20のタブ部21には凹部45内に位置し第一L字曲げ部24に向かって肉厚が徐々に厚くなる傾斜部27が形成されている。   The connecting portion 23 of the terminal fitting 20 is provided with a protruding portion 26 that supports the connector housing 40 apart from the attachment portion 50 and protrudes from the connector housing 40 toward the attachment portion 50. Is formed in an inclined portion 27 which is located in the recess 45 and gradually increases in thickness toward the first L-shaped bent portion 24.

次に、本実施形態である雄側コネクタの製造方法について説明する。   Next, the manufacturing method of the male connector which is this embodiment is demonstrated.

図6及び図7に示すように、まず、第1の金型に相当する第一金型60と第2の金型に相当する第二金型70とを組み合わせた成型金型内に端子金具20をセットした後に樹脂を射出してインサート成型し、これらの金型を嵌合方向に沿って型開きすることによって端子金具20が樹脂内に埋め込まれたコネクタハウジング40を成型する。   As shown in FIGS. 6 and 7, first, terminal fittings are formed in a molding die in which a first die 60 corresponding to a first die and a second die 70 corresponding to a second die are combined. After setting 20, resin is injected and insert-molded, and these molds are opened along the fitting direction to mold the connector housing 40 in which the terminal fitting 20 is embedded in the resin.

コネクタハウジング40の前方部分の領域を成形する第一金型60は開口縁部を上方向にして配置する。そして、端子金具20のタブ部21を図6に示すように第一金型60の中央部に位置し開口縁部よりやや奥側の位置にタブ部21の傾斜部27に対応するテーパ面61を有するタブ挿入孔62に挿入する。すると、タブ部21を挿入する過程でタブ部21の傾斜部27がタブ挿入孔62のテーパ面61に当接し、その挿入方向の力がテーパ面61に押し付けられることによって端子金具20を受け、端子金具20が横に押し付けられて固定される。   The first mold 60 for molding the region of the front portion of the connector housing 40 is arranged with the opening edge upward. Then, as shown in FIG. 6, the tab 21 of the terminal fitting 20 is located at the center of the first mold 60 and slightly tapered from the opening edge so as to correspond to the inclined portion 27 of the tab 21. Is inserted into the tab insertion hole 62 having Then, in the process of inserting the tab portion 21, the inclined portion 27 of the tab portion 21 contacts the tapered surface 61 of the tab insertion hole 62, and the force in the insertion direction is pressed against the tapered surface 61 to receive the terminal fitting 20. The terminal fitting 20 is pressed sideways and fixed.

傾斜部27がテーパ面61に当接したときには端子金具20の突出部26と第二L字曲げ部25とが当接する第一金具押さえ部63にセットされる。   When the inclined portion 27 comes into contact with the taper surface 61, the protruding portion 26 of the terminal fitting 20 and the second L-shaped bent portion 25 are set to the first fitting pressing portion 63 in contact.

端子金具20をセットした後、第二金型70の開口縁部を下方向にして第二金型70を第一金型60に覆い被せるように型締めする。この時に第一金型60の第一金具押さえ部63と対になる第二金具押さえ部71とによって端子金具20の突出部26を挟み込んだ金具押さえ部で固定する。   After the terminal fitting 20 is set, the second metal mold 70 is clamped so that the opening edge of the second metal mold 70 faces downward and the second metal mold 70 is covered with the first metal mold 60. At this time, the first metal piece holding part 63 of the first mold 60 and the second metal piece holding part 71 paired with the metal fitting holding part sandwiching the protruding part 26 of the terminal metal piece 20 are fixed.

次に、第二金型70に形成され端子金具20の第一L字曲げ部24の上方より合成樹脂材を第一金型60と第二金型70との間に形成されたキャビティ81に射出するゲート72から合成樹脂材を射出することによって端子金具20をインサート成型する。   Next, a synthetic resin material is formed in the cavity 81 formed between the first mold 60 and the second mold 70 from above the first L-shaped bent portion 24 of the terminal fitting 20 formed in the second mold 70. The terminal fitting 20 is insert-molded by injecting a synthetic resin material from the injection gate 72.

ゲート72から合成樹脂材を射出しているときには、端子金具20にはタブ挿入孔62に押し込まれる方向に力が作用し、端子金具20の傾斜部27がタブ挿入孔62のテーパ面61に押し付けられることによって端子金具20が横に押し付けられてタブ挿入孔62の側壁に密着して、更に端子金具20が固定される。   When the synthetic resin material is injected from the gate 72, a force is applied to the terminal fitting 20 in a direction to be pushed into the tab insertion hole 62, and the inclined portion 27 of the terminal fitting 20 is pressed against the tapered surface 61 of the tab insertion hole 62. As a result, the terminal fitting 20 is pressed sideways and brought into close contact with the side wall of the tab insertion hole 62, and the terminal fitting 20 is further fixed.

キャビティ81内に注入された合成樹脂材が固化した後、図7に示すようにそれぞれの金型を嵌合方向に沿って型開きすることによってコネクタハウジング40を取り出す。   After the synthetic resin material injected into the cavity 81 is solidified, the connector housing 40 is taken out by opening the respective molds along the fitting direction as shown in FIG.

最後に、コネクタハウジング40の凹部45の内壁面45Aと端子金具20のタブ部21とに密着する防水対策用の合成樹脂材であるポッティング材49を注入ノズル52によって先ほど完成したコネクタハウジング40の凹部45内に注入し、ポッティング材49を硬化させることによって雄側コネクタが完成する。   Finally, the potting material 49, which is a synthetic resin material for waterproofing, which is in close contact with the inner wall surface 45A of the concave portion 45 of the connector housing 40 and the tab portion 21 of the terminal fitting 20, is recessed by the injection nozzle 52 previously completed. The male connector is completed by injecting into 45 and hardening the potting material 49.

以上説明した実施形態によれば、キャビティ81内に合成樹脂材を射出した時には端子金具20を金具押さえ部とテーパ面61との二箇所により固定することができるうえに、端子金具20を挟み込んで固定することによって従来と比べてがたつきなく成型金型内に固定することができる。更にはゲート72を端子金具20が第一金型60に押し付けられる位置に配置したことによって端子金具20の位置精度が高いコネクタを製造することができる。   According to the embodiment described above, when the synthetic resin material is injected into the cavity 81, the terminal fitting 20 can be fixed by the two places of the fitting pressing portion and the tapered surface 61, and the terminal fitting 20 is sandwiched. By fixing, it can be fixed in the mold without rattling compared to the conventional case. Furthermore, by arranging the gate 72 at a position where the terminal fitting 20 is pressed against the first mold 60, a connector with high positional accuracy of the terminal fitting 20 can be manufactured.

また、嵌合力が集中するL字曲げ部をコネクタハウジング40の外側に配置したことによってそのL字曲げ部が変形するような状態になってもその影響は樹脂部には及ばないため、コネクタの抜差しによる樹脂部の破損を極力防止することができる。   Further, since the L-shaped bent portion where the fitting force is concentrated is arranged outside the connector housing 40, even if the L-shaped bent portion is deformed, the influence does not reach the resin portion. It is possible to prevent damage to the resin part due to insertion / extraction as much as possible.
