特開２０１７−４１３７６号公報JP 2017-41376 特開２０１７−７３２８４号公報JP 2017-73284 A

本発明は、ケーブルの接続が容易で防水性に優れたコンパクトなコネクタの提供を目的とする。   An object of the present invention is to provide a compact connector that can be easily connected to a cable and has excellent waterproof properties.

本発明に係る防水コネクタは、ケーブルの芯線を電気接続するためのターミナル端子と、前記ターミナル端子に向けて前記芯線を付勢する弾性部材と、前記弾性部材の付勢力を開放状態に切り換えるためのレバー部材とを備え、前記ターミナル端子及び弾性部材を収容したハウジングを有し、前記ハウジングは前記レバー部材の操作部が外部に突出するように当該レバー部材を収容してあり、前記ハウジングと前記レバー部材との間を止水するための防水ラバー部材を有することを特徴とする。
ここで、防水ラバー部材は前記ハウジングへのケーブルの挿入部を止水するケーブル止水部を有するのが好ましい。 A waterproof connector according to the present invention includes a terminal terminal for electrically connecting a core wire of a cable, an elastic member that biases the core wire toward the terminal terminal, and a biasing force of the elastic member for switching to an open state. A lever member, and housing the terminal terminal and the elastic member, the housing housing the lever member so that an operation portion of the lever member protrudes to the outside, and the housing and the lever It has the waterproof rubber member for water-stopping between members.
Here, it is preferable that the waterproof rubber member has a cable water stop portion that stops the insertion portion of the cable into the housing.

本発明においては、弾性部材をレバー部材でそのターミナル端子に向けて押圧する付勢力に対抗して開放状態に切り換えることで、ターミナル端子と弾性部材との間に隙間が生じケーブル芯線を挿入することができ、このレバー部材を元に戻すと、弾性部材とターミナル端子との間にケーブルの芯線を弾性挟持する。   In the present invention, a gap is created between the terminal terminal and the elastic member to insert the cable core wire by switching the elastic member to the open state against the urging force pressing the elastic member toward the terminal terminal with the lever member. When the lever member is returned to its original position, the cable core wire is elastically held between the elastic member and the terminal terminal.

コネクタの防水性を確保するために、ハウジング内にターミナル端子と弾性部材を収容した場合に、レバー部材は付勢状態と付勢力の開放状態を切り換えるのに、このレバー部材の操作部をハウジングの外側に突出させるのが操作性を確保する観点から好ましい。
そこで本発明は、レバー部材の操作部をハウジングの外側に突出させた状態で、ハウジングとレバー部材の間の隙間をゴム弾性変形する防水ラバー部材にて止水したものである。
これにより、レバー部材の操作部が動いてもそれに防水ラバー部材が追随するように変形し、切り換え操作性を維持しつつ、ハウジング内に水が浸入するのを防ぐことができる。 In order to secure the waterproofness of the connector, when the terminal terminal and the elastic member are accommodated in the housing, the lever member switches the urging state and the urging force open state. Projecting outward is preferable from the viewpoint of ensuring operability.
Therefore, in the present invention, water is stopped by a waterproof rubber member that elastically deforms the gap between the housing and the lever member in a state where the operation portion of the lever member is projected to the outside of the housing.
Thereby, even if the operation part of a lever member moves, it deform | transforms so that a waterproof rubber member may follow it, and it can prevent that water permeates into a housing, maintaining switching operativity.

本発明において、ハウジングと前記ケーブルの接続状態を保持するためのカバー部材を有し、前記カバー部材を前記ハウジングに装着すると、前記レバー部材を前記弾性部材の付勢状態に切り換えるようにしてもよい。
例えば、弾性部材の開放状態では、レバー部材の操作部がハウジングのカバー部材を装着する面より外側に位置するようになっていて、カバー部材をハウジングに装着しようとすると、このカバー部材に操作部が当たり、この操作部が押し込まれるようになっている例が挙げられる。
これにより、弾性部材の付勢力を開放状態にしたままになるのを防ぐ。 In the present invention, a cover member for holding a connection state between the housing and the cable may be provided, and when the cover member is attached to the housing, the lever member may be switched to the biased state of the elastic member. .
For example, when the elastic member is in the open state, the operation portion of the lever member is positioned outside the surface on which the cover member of the housing is mounted, and when the cover member is to be mounted on the housing, the operation portion In this example, the operation unit is pushed in.
This prevents the biasing force of the elastic member from being left open.

本発明に係る防水コネクタは、弾性部材をレバー部材の切り換え操作により開放状態にし、ケーブルの芯線をターミナル端子と弾性部材との間に挿入し、レバー部材を元に戻すだけで、ケーブルの電気接続及び防水を図ることができるので、現場での接続作業性に優れる。   The waterproof connector according to the present invention opens the elastic member by switching the lever member, inserts the core wire of the cable between the terminal terminal and the elastic member, and simply returns the lever member to the electrical connection of the cable. In addition, since waterproofing can be achieved, the connection workability at the site is excellent.

In this specification, the fitting surface side of the connector is expressed as the front.
An elastic member 40 is attached to the terminal terminal 30.
The elastic member 40 has a bent portion 41 formed on the lower side from the base portion 44, and has a locking portion 42 that is folded upward via a U-shaped push-up portion 41a.
The locking part 42 has a gate structure so as to have an opening 43. By positioning the receiving part 32 inside the opening 43, the locking part 42 does not shift from side to side when the locking part 42 moves up and down. It has become.
The lance 44a provided on the base portion 44 is locked to the terminal terminal side, and the gate-shaped locking portion 42 is held by the receiving portion 32 of the terminal terminal 30 before the core wire is connected.
When the contact portion 30 a of the terminal terminal 30 is incorporated inside the housing 10, it is held by a resin-made terminal holding member 20 that is locked to the housing 10 via a lance 21.
This state is shown in FIG. 5A and corresponds to the test finger.
In addition, the pivoting boss portion provided with the resin lever members 50 on both sides from the rear side of the housing 10 is incorporated inside the housing 10 so as to be a pivotal fulcrum portion 52.
The lever member 50 includes an operation portion 51 that protrudes to the outside of the housing 10 and an action portion 53 that extends to the opposite side of the fulcrum portion 52.
In FIG. 1, when the operation portion 51 is pushed down, the action portion 53 pushes up the push-up portion 41 a that is folded back into the U shape of the elastic member 40, and the locking portion 42 moves upward.
Thereby, as shown in FIG.1 (b), the latching | locking part 42 will leave | separate from the upper surface of the terminal terminal 30, and it will be in the open state which made the clearance gap between them.

図１に基づいてケーブルの接続例を説明する。
図１に示したケーブル１の例は、３本の単線２からなり、それぞれの単線２の被覆部を剥がして芯線３を露出させてある。
図１（ａ）は、芯線３をハウジングに接続する前である。
この状態では、弾性部材４０の係止部４２がその弾性付勢力にてターミナル端子の上面に接触している。
図１（ｂ）に示すように、レバー部材５０のハウジング１０から外側に突出している操作部５１を下方に向けて押し下げると、てこの原理にて反対側の作用部５３が弾性部材４０のＵ字状の押上部４１ａを下側から押し上げることで、弾性部材４０の係止部４２がターミナル端子３０の上面（受け部３２）から離れ、開放状態になる。
この操作部５１を下側に下げた状態は、そのまま維持されるようになっている。
この状態で、図１（ｃ）に示すようにケーブル１の芯線３を係止部４２とターミナル端子３０の上面との間の開放部に挿入することができ、操作部５１を上方に持ち上げると、芯線３を係止部４２の付勢力にてターミナル端子側に押圧し、挟持された状態で電気接続されることになる。 A cable connection example will be described with reference to FIG.
The example of the cable 1 shown in FIG. 1 includes three single wires 2, and the core wire 3 is exposed by peeling off the covering portion of each single wire 2.

In this state, the locking portion 42 of the elastic member 40 is in contact with the upper surface of the terminal terminal by its elastic biasing force.
As shown in FIG. 1B, when the operation portion 51 protruding outward from the housing 10 of the lever member 50 is pushed downward, the action portion 53 on the opposite side of the lever member 50 is moved to the U of the elastic member 40 by the lever principle. By pushing up the letter-shaped push-up portion 41a from the lower side, the engaging portion 42 of the elastic member 40 is separated from the upper surface (receiving portion 32) of the terminal terminal 30 and is opened.
The state where the operation unit 51 is lowered is maintained as it is.
In this state, as shown in FIG. 1C, the core wire 3 of the cable 1 can be inserted into the open portion between the locking portion 42 and the upper surface of the terminal terminal 30, and when the operation portion 51 is lifted upward, The core wire 3 is pressed toward the terminal terminal side by the urging force of the locking portion 42 and is electrically connected in a sandwiched state.

本発明においては、このレバー部材５０の操作性を確保しつつ、防水を図った点に特徴がある。
本実施例は、図２に示すように３Ｐタイプのコネクタであって、ハウジング１０には３つの筒状部からなる単線挿入孔１２と、それぞれの単線２に対応したレバー部材５０の取付部（取付孔）１３を有している。
図６（ａ）に部品構成図を示すように防水ラバー部材６０は、これらの単線挿入孔１２と取付部１３とを塞ぐために、周囲壁１３ａに装着される。
図１は、その装着断面図となる。
防水ラバー部材６０は、単線挿入孔１２の位置に対応させたケーブル止水部６２と、レバー部材５０の取付部１３の位置に対応させたレバー止水部６１とを有する。
ケーブル止水部６２は、内側に円錐台状の止水片６２ａを形成してあり、挿入された単線２の被覆部の外周にわたって弾性接触し、その部分を止水する。
レバー止水部６１は、操作部５１を外部に突出させるための突出口６１ａと、筒状の弾性変形部６１ｂとを有している。
突出口６１ａの内周部は、操作部５１に設けた段差部５１ａに密着し、その部分で止水する。
これにより、操作部５１の上下方向の回動の動きに合せて、筒状の弾性変形部が変形するので、レバー部材の操作性に優れる。 The present invention is characterized in that it is waterproof while ensuring the operability of the lever member 50.
This embodiment is a 3P type connector as shown in FIG. 2, and the housing 10 has a single wire insertion hole 12 formed of three cylindrical portions and an attachment portion of a lever member 50 corresponding to each single wire 2 ( Mounting holes) 13.
6A, the waterproof rubber member 60 is attached to the peripheral wall 13a in order to close the single wire insertion hole 12 and the attachment portion 13. As shown in FIG.
FIG. 1 is a sectional view of the mounting.
The waterproof rubber member 60 has a cable water stop portion 62 corresponding to the position of the single wire insertion hole 12 and a lever water stop portion 61 corresponding to the position of the attachment portion 13 of the lever member 50.
The cable water stop portion 62 has a frustoconical water stop piece 62a formed inside, and elastically contacts the outer periphery of the covering portion of the inserted single wire 2 to stop the portion.
The lever water stop 61 has a projecting port 61a for projecting the operation unit 51 to the outside, and a cylindrical elastic deformation part 61b.
The inner peripheral portion of the protrusion 61a is in close contact with the step portion 51a provided in the operation portion 51, and water is stopped at that portion.
Thereby, since the cylindrical elastic deformation portion is deformed in accordance with the movement of the operation portion 51 in the vertical direction, the operability of the lever member is excellent.

図２及び図３に示すように、コネクタはハウジング１０にケーブル１を接続後にこのケーブル１がハウジング１０から抜けないように、ハウジング１０の外周面からケーブル１の外周部に跨がってカバー部材７０を装着する例になっている。
カバー部材７０は、上カバー７２と下カバー７１とが開閉可能になるように、枢着部７３にて連結してある。
また、上カバー７２，下カバー７１には、ケーブル１の外周部に係止するケーブル押圧部７２ａ，７１ａを形成してある。
また、上カバー７２と下カバー７１を閉じると相互に係止し、閉じた状態をロックする係止爪部７１ｂと被係止部７２ｂを有している。
上下のカバーを閉じる際に、下カバー７１をハウジング１０の下面側に位置させると、図２（ｂ）に示すようにレバー部材５０の操作部５１が下カバー７１の内側の側面に当たり、操作部５１が開放状態になっていても元に戻されるので、弾性部材４０の係止部４２が芯線３に係止しないまま、カバーが閉じるのを防止する。
本実施例では、図１，２に示すように芯線３がターミナル端子３０に接続されるのを確認するための開口部１４をハウジング１０に設けてあり、図３（ｂ）に断面図を示すように上カバー７２の内側には、この開口部１４を塞ぐシート材７４を取り付けてある。 As shown in FIGS. 2 and 3, the connector covers the outer peripheral surface of the cable 1 from the outer peripheral surface of the housing 10 so that the cable 1 does not come out of the housing 10 after the cable 1 is connected to the housing 10. In this example, 70 is attached.
The cover member 70 is connected by a pivot 73 so that the upper cover 72 and the lower cover 71 can be opened and closed.
Further, the upper cover 72 and the lower cover 71 are formed with cable pressing portions 72 a and 71 a that are engaged with the outer peripheral portion of the cable 1.
Moreover, when the upper cover 72 and the lower cover 71 are closed, it has the latching claw part 71b and the to-be-latched part 72b which latch each other and lock the closed state.
When closing the upper and lower covers, if the lower cover 71 is positioned on the lower surface side of the housing 10, the operation portion 51 of the lever member 50 hits the inner side surface of the lower cover 71 as shown in FIG. Even if 51 is in an open state, it is returned to its original state, so that the cover is prevented from closing without the locking portion 42 of the elastic member 40 being locked to the core wire 3.
In this embodiment, as shown in FIGS. 1 and 2, an opening 14 for confirming that the core wire 3 is connected to the terminal terminal 30 is provided in the housing 10, and a sectional view is shown in FIG. Thus, a sheet material 74 that closes the opening 14 is attached to the inside of the upper cover 72.
