Description

本発明は分岐コネクタに関する。   The present invention relates to a branch connector.

既存のケーブル（電線）の中間部に対して、当該電線とは別のケーブル（電線）の一端を接続するための分岐コネクタの従来例としては、例えば特許文献１に開示されたものがある。
この分岐コネクタは、絶縁性（合成樹脂製）のハウジングと、ハウジングに支持した中継コンタクトと、を具備するものである。ハウジングは、第一対向面を有する第一分割ハウジングと、第二対向面を有する第二分割ハウジングと、第一分割ハウジングと第二分割ハウジングを、第一対向面と第二対向面を互いに接離可能として接続する連結部と、第一対向面と第二対向面が互いに接触したときに当該接触状態を保持するロック手段と、を一体的に備えている。中継コンタクトは、第一分割ハウジングの第一対向面に固定状態で支持したものであり、ケーブル圧接片及びケーブル圧着部を有している。 As a conventional example of a branch connector for connecting one end of a cable (electric wire) different from the electric wire to an intermediate portion of an existing cable (electric wire), there is one disclosed in Patent Document 1, for example.
This branch connector includes an insulating (synthetic resin) housing and a relay contact supported by the housing. The housing includes a first divided housing having a first opposed surface, a second divided housing having a second opposed surface, a first divided housing and a second divided housing, and the first opposed surface and the second opposed surface being in contact with each other. A connecting portion that is connected to be separable and a lock unit that holds the contact state when the first facing surface and the second facing surface contact each other are integrally provided. The relay contact is supported in a fixed state on the first facing surface of the first divided housing, and has a cable pressure contact piece and a cable crimping portion.

以上構成の分岐コネクタを介して、既存のケーブル（以下、第一ケーブルと呼ぶ）に対して別個のケーブル（以下、第二ケーブルと呼ぶ）の一端を接続するには、まず第一対向面と第二対向面を離間させ、その上で第一ケーブルの中間部を第二分割ハウジングに支持させ、さらに第二ケーブルの一端を中継コンタクトのケーブル圧着部に圧着する。次いで、第二分割ハウジングを第一分割ハウジングに接近させることにより第一対向面を第二対向面に接触させ、ロック手段によって当該接触状態を保持する。すると第二分割ハウジングが第一ケーブルの中間部を中継コンタクトのケーブル圧接片に押圧するので、第一ケーブルの中間部が中継コンタクトのケーブル圧接片に圧接される。
その結果、第一ケーブルと第二ケーブルが中継コンタクトを介して互いに電気的に導通する。 In order to connect one end of a separate cable (hereinafter referred to as the second cable) to the existing cable (hereinafter referred to as the first cable) via the branch connector having the above configuration, first, the first facing surface and The second facing surface is separated, and the intermediate portion of the first cable is supported on the second divided housing, and one end of the second cable is further crimped to the cable crimping portion of the relay contact. Next, the first opposed surface is brought into contact with the second opposed surface by bringing the second divided housing closer to the first divided housing, and the contact state is held by the locking means. Then, since the second divided housing presses the intermediate portion of the first cable against the cable pressure contact piece of the relay contact, the intermediate portion of the first cable is pressed against the cable pressure contact piece of the relay contact.
As a result, the first cable and the second cable are electrically connected to each other via the relay contact.

中継コンタクト６０はばね弾性を備えた銅合金（例えばリン青銅、ベリリウム銅、チタン銅）やコルソン系銅合金の薄板を順送金型（スタンピング）を用いて図示形状に成形加工したものであり、表面にニッケルメッキで下地を形成した後に、金メッキや錫銅めっきを施している。
中継コンタクト６０は、基片６１と、基片６１の前後両端から基片６１に対して直交する方向に延びる一対のケーブル圧接片６２と、後方のケーブル圧接片６２から右側に延びる延出片６４と、延出片６４の右端部の前面に突設した円弧形状のケーブル圧着部６５と、を一体的に具備している。図３（ａ）に示すようにケーブル圧着部６５は複数の圧着片６６を具備している。基片６１の中心部には円形の位置決め孔６１ａが形成してある。また前後のケーブル圧接片６２にはスリットからなる圧接用溝６３がそれぞれ形成してある。
中継コンタクト６０は、第一ケーブル７０及び第二ケーブル７５が接続するものである。
第一ケーブル７０と第二ケーブル７５は、導電性及び可撓性を有する材料からなる芯線７１、７６（撚り線や単線）の表面をチューブ状かつ可撓性を有する絶縁チューブ７２、７７でそれぞれ被覆したものである。第一ケーブル７０は自動車等の内部に最初から配線した電源と接続する既存のケーブルである。一方、第二ケーブル７５は第一ケーブル７０に対して後から追加で接続するケーブルであり、その一端（前端）には例えばＥＴＣ用端末等が接続してある。 The relay contact 60 is formed by processing a thin plate of a copper alloy (for example, phosphor bronze, beryllium copper, titanium copper) having a spring elasticity or a Corson copper alloy into a shape shown in the drawing using a progressive die (stamping). After the base is formed by nickel plating, gold plating or tin copper plating is applied.
The relay contact 60 includes a base piece 61, a pair of cable pressure contact pieces 62 extending in a direction perpendicular to the base piece 61 from both front and rear ends of the base piece 61, and an extension piece 64 extending rightward from the rear cable pressure contact piece 62. And an arc-shaped cable crimping portion 65 projecting from the front surface of the right end portion of the extension piece 64. As shown in FIG. 3A, the cable crimping portion 65 includes a plurality of crimping pieces 66. A circular positioning hole 61 a is formed at the center of the base piece 61. The front and rear cable pressure contact pieces 62 are each formed with a pressure contact groove 63 formed of a slit.
The relay contact 60 connects the first cable 70 and the second cable 75.
The first cable 70 and the second cable 75 are tube-like and flexible insulating tubes 72 and 77 having surfaces of core wires 71 and 76 (stranded wires and single wires) made of a conductive and flexible material, respectively. It is coated. The first cable 70 is an existing cable that is connected to a power source wired from the beginning inside an automobile or the like. On the other hand, the second cable 75 is a cable that is additionally connected to the first cable 70 later, and an ETC terminal or the like is connected to one end (front end) thereof.

中継コンタクト６０は絶縁ハウジング１５に対して取り付ける前に第二ケーブル７５と一体化する。即ち、図３（ａ）に示す状態のケーブル圧着部６５に対して第二ケーブル７５の後端部を載せた後に、図３（ｂ）に示すように各圧着片６６を第二ケーブル７５の後端部に対してかしめる。すると、絶縁チューブ７７の後端から後方に突出（露出）させた芯線７６の後端部に対して圧着片６６が圧着され（接触し）、中継コンタクト６０と第二ケーブル７５の後端部が一体化する。
次いで、展開状態にある絶縁ハウジング１５の第一分割ハウジング１６のコンタクト取付溝１８に対して中継コンタクト６０の下部を嵌合し、かつ位置決め孔６１ａを位置決め突起１８ａに対して嵌合することにより、第一分割ハウジング１６に対して着脱可能に取り付ける（図４参照）。中継コンタクト６０を第一分割ハウジング１６に取り付けると、前後の第一ケーブル取付溝１９を通る軸線上に前後の圧接用溝６３が位置する。このとき、第二ケーブル取付溝２０に対して第二ケーブル７５の他端近傍部（後端近傍部）の下半部が嵌合する（接触する）。
続いて、図５に示すように、第一分割ハウジング１６を下方から第一ケーブル７０の中間部に対して接近させ、一対のケーブル圧接片６２の圧接用溝６３の入口側端部（上端部）に第一ケーブル７０の中間部を嵌め込む（圧接用溝６３の入口側端部で第一ケーブル７０の絶縁チューブ７２を挟持する）。
次いで、前後の連結部４５を折り曲げ線４６に沿って折り曲げながら第一分割ハウジング１６と第二分割ハウジング３０を接近方向に相対回転させる。するとケーブル押圧突起３２が、第一ケーブル７０の中間部を圧接用溝６３の奥側（下方）に押し込みながら前後のケーブル圧接片６２の間の空間に入り込み、第一突片３９の貫通孔４０内に前後の仮ロック用突起２６が位置し、さらに前後の仮ロック用突起２６に係合突起４１が係合する。また、このとき第一突片３９より突出量（上下寸法）が小さい第二突片４２は、第一分割ハウジング１６の上面と干渉することなく、第一分割ハウジング１６のロック用突起２７が形成された側面に接近し、第二突片４２の貫通孔４３内にロック用突起２７が円滑に進入する。このように前後の仮ロック用突起２６と係合突起４１が係合することにより第一分割ハウジング１６と第二分割ハウジング３０は仮ロック状態となる。この仮ロック状態では、第一分割ハウジング１６（第一対向面１７）及び第二分割ハウジング３０（第二対向面３１）の自由端（連結部４５と反対側の端部）は互いに離れた状態にあるため、作業者は、中継コンタクト６０（圧接用溝６３）に圧接させようとしている第一ケーブル７０が中継コンタクト６０の圧接用溝６３の入口側端部に進入しているか否かを、第一分割ハウジング１６（第一対向面１７）及び第二分割ハウジング３０（第二対向面３１）の自由端の間に形成された隙間から視認できる。 The relay contact 60 is integrated with the second cable 75 before being attached to the insulating housing 15. That is, after the rear end portion of the second cable 75 is placed on the cable crimping portion 65 in the state shown in FIG. 3A, each crimping piece 66 is attached to the second cable 75 as shown in FIG. Caulking against the rear edge. Then, the crimping piece 66 is crimped (contacted) to the rear end portion of the core wire 76 protruding backward (exposed) from the rear end of the insulating tube 77, and the rear end portion of the relay contact 60 and the second cable 75 is connected. Integrate.
Next, by fitting the lower part of the relay contact 60 to the contact mounting groove 18 of the first divided housing 16 of the insulating housing 15 in the expanded state and fitting the positioning hole 61a to the positioning projection 18a, It attaches to the 1st division | segmentation housing 16 so that attachment or detachment is possible (refer FIG. 4). When the relay contact 60 is attached to the first divided housing 16, the front and rear pressure welding grooves 63 are positioned on the axis passing through the front and rear first cable attachment grooves 19. At this time, the lower half of the second cable 75 is fitted (contacted) with the second cable attachment groove 20 in the vicinity of the other end (rear end).
Subsequently, as shown in FIG. 5, the first divided housing 16 is approached from the lower side to the middle portion of the first cable 70, and the inlet side end portion (upper end portion) of the pressure contact groove 63 of the pair of cable pressure contact pieces 62. ) Is inserted into the intermediate portion of the first cable 70 (the insulating tube 72 of the first cable 70 is clamped at the inlet side end portion of the pressure welding groove 63).
Next, the first divided housing 16 and the second divided housing 30 are relatively rotated in the approaching direction while the front and rear connecting portions 45 are bent along the folding line 46. Then, the cable pressing protrusion 32 enters the space between the front and rear cable pressing pieces 62 while pushing the intermediate portion of the first cable 70 into the back side (downward) of the pressing groove 63, and the through hole 40 of the first protruding piece 39. The front and rear temporary locking projections 26 are positioned inside, and the engagement projection 41 is engaged with the front and rear temporary locking projections 26. At this time, the second protrusion 42 having a smaller protrusion amount (vertical dimension) than the first protrusion 39 does not interfere with the upper surface of the first divided housing 16, and the locking protrusion 27 of the first divided housing 16 is formed. The locking projection 27 smoothly enters the through hole 43 of the second projecting piece 42 by approaching the formed side surface. Thus, the front and rear temporary locking projections 26 and the engaging projections 41 are engaged, whereby the first divided housing 16 and the second divided housing 30 are in a temporary locked state. In this temporarily locked state, the free ends (ends opposite to the connecting portion 45) of the first divided housing 16 (first opposed surface 17) and the second divided housing 30 (second opposed surface 31) are separated from each other. Therefore, the operator determines whether or not the first cable 70 to be in pressure contact with the relay contact 60 (pressure contact groove 63) has entered the inlet side end of the pressure contact groove 63 of the relay contact 60. It can be visually recognized from the gap formed between the free ends of the first divided housing 16 (first opposed surface 17) and the second divided housing 30 (second opposed surface 31).

第一ケーブル７０が中継コンタクト６０の圧接用溝６３内に進入していることを確認した後に、図示を省略した工具（例えば、プライヤー）によって第一分割ハウジング１６及び第二分割ハウジング３０の自由端を接近する方向に押圧して、仮ロック用突起２６と係合している係合突起４１をロック用突起２５に対して係合させる。これにより第一分割ハウジング１６と第二分割ハウジング３０は第一対向面１７と第二対向面３１が面接触し（または微小隙間を形成しながら対向し）かつ前後の第一ケーブル取付溝３３と第二ケーブル取付溝３４が第一ケーブル７０の前後二カ所の上半部と第二ケーブル７５の上記他端近傍部の上半部にそれぞれ嵌り込んだ（接触した）閉状態に保持（ロック）される。またケーブル押圧突起３２及び第一ケーブル７０の中間部がコンタクト取付溝１８の奥側（底面側）にさらに進入することにより、圧接用溝６３の内面（左右両面）によって絶縁チューブ７２が破られ、圧接用溝６３の内面が芯線７１に接触する（圧接する）。また、第一ケーブル７０の中間部の前後に位置する２つの部位の下半部が前後の第一ケーブル取付溝１９に対してそれぞれ嵌る（接触する）。そのため分岐コネクタ１０の内部において第一ケーブル７０の中間部と第二ケーブル７５の上記他端近傍部（後端近傍部）が互いに電気的に導通する。   After confirming that the first cable 70 has entered the pressure contact groove 63 of the relay contact 60, the free ends of the first split housing 16 and the second split housing 30 with a tool (eg, pliers) (not shown). Is pushed in the approaching direction, and the engaging protrusion 41 engaged with the temporary locking protrusion 26 is engaged with the locking protrusion 25. As a result, the first divided housing 16 and the second divided housing 30 have the first opposed surface 17 and the second opposed surface 31 in surface contact (or opposed while forming a minute gap) and the front and rear first cable mounting grooves 33. The second cable mounting groove 34 is fitted in (contacted with) the upper half of the first cable 70 at the front and rear two locations and the upper half of the second cable 75 in the vicinity of the other end (held). Is done. Further, when the intermediate portion of the cable pressing protrusion 32 and the first cable 70 further enters the back side (bottom side) of the contact mounting groove 18, the insulating tube 72 is broken by the inner surface (left and right both sides) of the pressure welding groove 63, The inner surface of the pressure contact groove 63 is in contact with the core wire 71 (pressure contact). In addition, the lower half portions of the two portions located at the front and rear of the intermediate portion of the first cable 70 are fitted into (contact with) the front and rear first cable mounting grooves 19, respectively. Therefore, the middle portion of the first cable 70 and the vicinity of the other end (rear end portion) of the second cable 75 are electrically connected to each other inside the branch connector 10.

また第一分割ハウジング１６と第二分割ハウジング３０が閉状態になると、第一分割ハウジング１６の嵌合壁２３Ａ、２３Ｂ、及び２３Ｃが、第二分割ハウジング３０の嵌合溝３７Ａ、３７Ｂ、及び３７Ｃに対してそれぞれ嵌合する（図７、図８参照）。
第一分割ハウジング１６と第二分割ハウジング３０を閉状態にしても第一分割ハウジング１６の第一対向面１７と第二分割ハウジング３０の第二対向面３１の間には微小な隙間が形成される可能性がある。しかし第一分割ハウジング１６の嵌合壁２３Ａ、２３Ｂ、及び２３Ｃが、第二分割ハウジング３０の嵌合溝３７Ａ、３７Ｂ、及び３７Ｃに対してそれぞれ嵌合する結果、嵌合壁２３Ａ、２３Ｂ、２３Ｃ及び嵌合溝３７Ａ、３７Ｂ、３７Ｃを形成しない場合に比べて、第一対向面１７と第二対向面３１の間の上記隙間の第一分割ハウジング１６及び第二分割ハウジング３０の外周縁部から中継コンタクト６０までの沿面距離が長くなる。そのため分岐コネクタ１０の外側にある水や埃などが第一対向面１７と第二対向面３１の間の上記隙間を通り抜けて中継コンタクト６０や第一ケーブル７０及び第二ケーブル７５の中継コンタクト６０との接続部（芯線７１及び芯線７６の後端部）に接触するおそれを低減できる。 When the first divided housing 16 and the second divided housing 30 are closed, the fitting walls 23A, 23B, and 23C of the first divided housing 16 are fitted into the fitting grooves 37A, 37B, and 37C of the second divided housing 30. (See FIGS. 7 and 8).
Even when the first divided housing 16 and the second divided housing 30 are closed, a minute gap is formed between the first facing surface 17 of the first divided housing 16 and the second facing surface 31 of the second divided housing 30. There is a possibility. However, the fitting walls 23A, 23B, and 23C of the first divided housing 16 are fitted into the fitting grooves 37A, 37B, and 37C of the second divided housing 30, respectively. Compared with the case where the fitting grooves 37 </ b> A, 37 </ b> B, 37 </ b> C are not formed, from the outer peripheral edge portions of the first divided housing 16 and the second divided housing 30 in the gap between the first facing surface 17 and the second facing surface 31. The creepage distance to the relay contact 60 is increased. Therefore, water, dust or the like outside the branch connector 10 passes through the gap between the first facing surface 17 and the second facing surface 31 and the relay contact 60, the first cable 70, and the relay contact 60 of the second cable 75. It is possible to reduce the risk of contact with the connecting portions (the rear ends of the core wire 71 and the core wire 76).

さらに第一分割ハウジング１６と第二分割ハウジング３０が閉状態になると、メインパッキン５０の第一構成部５１、第二構成部５２、及び第三構成部５３が第二分割ハウジング３０のパッキン取付用溝３８Ａ、３８Ｂ、及び３８Ｃに対して水密状態（及び気密状態）で嵌合すると共に、半円状部５４及び半円状部５５の上面と対応する各サブパッキン５７の下面が互いに水密状態（及び気密状態）で接触し、さらに半円状部５４、５５、及びサブパッキン５７の内面が対応する第一ケーブル７０（絶縁チューブ７２）と第二ケーブル７５（絶縁チューブ７７）の一部の外周面全体に水密状態（及び気密状態）で接触する。
そのため、半円状凹部３５、３６、及びパッキン取付用溝３８Ａ、３８Ｂ、３８Ｃ並びにメインパッキン５０及び各サブパッキン５７を設けない場合に比べて、第一対向面１７と第二対向面３１の間の上記隙間の第一分割ハウジング１６及び第二分割ハウジング３０の外周縁部から中継コンタクト６０までの沿面距離が長くなる。さらに、仮に分岐コネクタ１０の外側にある水や埃などが嵌合壁２３Ａ、２３Ｂ、２３Ｃと嵌合溝３７Ａ、３７Ｂ、３７Ｃの間を通り抜けて、嵌合壁２３Ａ、２３Ｂ、２３Ｃ及び嵌合溝３７Ａ、３７Ｂ、３７Ｃの内側に進入したとしても、この水や埃が中継コンタクト６０側へ進入するのを、半円状凹部３５、３６、及びパッキン取付用溝３８Ａ、３８Ｂ、３８Ｃ並びにメインパッキン５０及び各サブパッキン５７によって効果的に防止できる。 Further, when the first divided housing 16 and the second divided housing 30 are closed, the first component 51, the second component 52, and the third component 53 of the main packing 50 are used for attaching the packing of the second divided housing 30. The grooves 38A, 38B, and 38C are fitted in a watertight state (and an airtight state), and the upper surfaces of the semicircular portion 54 and the semicircular portion 55 and the lower surfaces of the respective sub-packings 57 are in a watertight state ( And the outer circumference of a part of the first cable 70 (insulating tube 72) and the second cable 75 (insulating tube 77) to which the inner surfaces of the semicircular portions 54 and 55 and the sub packing 57 correspond. Contact the entire surface in a watertight (and airtight) state.
Therefore, compared with the case where the semicircular recesses 35 and 36, the packing mounting grooves 38A, 38B, and 38C, the main packing 50, and the sub-packings 57 are not provided, the gap between the first facing surface 17 and the second facing surface 31 is increased. The creepage distance from the outer peripheral edge of the first divided housing 16 and the second divided housing 30 to the relay contact 60 in the gap is increased. Furthermore, if water or dust outside the branch connector 10 passes between the fitting walls 23A, 23B, 23C and the fitting grooves 37A, 37B, 37C, the fitting walls 23A, 23B, 23C and the fitting grooves Even if it enters the inside of 37A, 37B, and 37C, the water and dust enter the relay contact 60 side to prevent the semicircular recesses 35 and 36, the packing mounting grooves 38A, 38B, and 38C, and the main packing 50 from entering. And each sub-packing 57 can prevent effectively.
