Description

本発明は、コイル装置に関する。   The present invention relates to a coil device.

従来より、例えばソレノイド等に組み込まれるコイル装置として、コイルボビンの天面に、コイル端子の本体部を収容する溝部と、コイル端子のアンカー部を収容する凹部とを一体に形成したものがある（例えば、特許文献１参照）。   Conventionally, for example, as a coil device incorporated in a solenoid or the like, there is one in which a groove portion for accommodating a main body portion of a coil terminal and a concave portion for accommodating an anchor portion of a coil terminal are integrally formed on the top surface of a coil bobbin (for example, , See Patent Document 1).

コイル端子の本体部の一端側には、電源コネクタが差し込まれる接続部（固定コネクタ）が設けられている。その一方で、他端側にはコイルボビンに巻回されるコイルの端部が係止されるヒュージング部が設けられており、電源コネクタからの電力をコイル端子を介してコイルに供給できるようになっている。   A connection portion (fixed connector) into which the power connector is inserted is provided on one end side of the main body portion of the coil terminal. On the other hand, the other end side is provided with a fusing portion for locking the end portion of the coil wound around the coil bobbin so that power from the power connector can be supplied to the coil via the coil terminal. It has become.

そして、この特許文献１では、コイルボビンの凹部に収容されたアンカー部の上から接着剤を凹部内に充填することにより、コイル端子の抜けを防止できるようにしている。   And in this patent document 1, it is made possible to prevent a coil terminal from falling out by filling the concave portion with an adhesive from above the anchor portion accommodated in the concave portion of the coil bobbin.

特開２００２−２８９４２２号公報JP 2002-289422 A

ところで、上記従来技術にあっては、コイル端子のコイルボビンへの圧入方向と、電源コネクタの接続部（固定コネクタ）への抜き差し方向とが平行に一致していることになる。この場合、電源コネクタを接続部へ繰り返し抜き差ししたとしてもコイル端子が容易に抜けてしまわないように、コイル端子の保持強度を高めることが望まれる。   By the way, in the said prior art, the press-fit direction to the coil bobbin of a coil terminal and the insertion / extraction direction to the connection part (fixed connector) of a power supply connector correspond in parallel. In this case, it is desirable to increase the holding strength of the coil terminal so that the coil terminal does not easily come off even if the power connector is repeatedly inserted into and removed from the connection portion.

しかしながら、上記従来技術にあっては、コイル端子のアンカー部を接着剤で固定しているだけなので、コイル端子の抜け方向への保持強度が弱く、コイル端子が容易に抜けてしまう恐れがあった。   However, in the above prior art, since the anchor portion of the coil terminal is only fixed with an adhesive, the holding strength of the coil terminal in the removal direction is weak, and the coil terminal may be easily detached. .

そこで、本発明は、コイル端子の保持強度を高めてコイル端子の圧入方向と電源コネクタの抜き差し方向とを平行に一致させた場合にもコイル端子を抜け難くすることのできるコイル装置を得ることを目的とする。   Therefore, the present invention is to obtain a coil device that can prevent the coil terminal from being easily pulled out even when the holding strength of the coil terminal is increased and the press-fitting direction of the coil terminal and the inserting / removing direction of the power connector are made to coincide in parallel. Objective.

上記目的を達成するために、本発明の第１の特徴は、コイルが巻回されるコイルボビンと、前記コイルに接続されるコイル端子を有するとともに、電源コネクタが抜き差し自在な固定コネクタと、を備え、前記コイル端子を、前記電源コネクタの抜き差し方向と平行に一致させて前記固定コネクタのケーシングに圧入固定するとともに、前記コイルボビンに、前記コイル端子を押さえて前記ケーシングへの圧入方向と逆方向の前記コイル端子の移動を規制するリブを設け、前記コイルボビンには、前記固定コネクタ側に開口する中空箱状のコイル端子収容部が形成されており、当該コイル端子収容部内に前記リブが設けられており、前記コイル端子は、当該コイル端子を前記ケーシングに圧入固定した状態で、前記ケーシングへの圧入方向と逆方向に突出しており、前記コイルボビンの前記固定コネクタへの取付方向が前記コイル端子の圧入方向と一致していることを要旨とする。 In order to achieve the above object, a first feature of the present invention includes a coil bobbin around which a coil is wound, and a fixed connector having a coil terminal connected to the coil and a power connector that can be freely inserted and removed. The coil terminal is press-fitted and fixed to the casing of the fixed connector so as to be parallel to the insertion / removal direction of the power connector, and the coil terminal is pressed against the coil bobbin in the direction opposite to the press-fitting direction into the casing. A rib for restricting the movement of the coil terminal is provided , and the coil bobbin is formed with a hollow box-like coil terminal accommodating portion that opens to the fixed connector side, and the rib is provided in the coil terminal accommodating portion. The coil terminal is in a state in which the coil terminal is press-fitted and fixed to the casing, Protrudes in a direction, and summarized in that the mounting direction to the fixed connector of the coil bobbin coincides with the press-fitting direction of the coil terminals.

第２の特徴は、前記電源コネクタの抜き方向と、前記コイル端子の圧入方向とが同じになるようにしたことを要旨とする。   The gist of the second feature is that the direction in which the power connector is pulled out is the same as the direction in which the coil terminal is press-fitted.

第３の特徴は、前記コイルボビンと前記固定コネクタとに、これらコイルボビンと固定コネクタとを合体させる係合部を設けるとともに、前記リブは、前記係合部の係合状態において前記コイル端子に接触して押さえることを要旨とする。   A third feature is that the coil bobbin and the fixed connector are provided with an engaging portion for combining the coil bobbin and the fixed connector, and the rib contacts the coil terminal in the engaged state of the engaging portion. The gist is to hold it down.

本発明によれば、コイル端子を電源コネクタの抜き差し方向と平行に一致させて固定コネクタのケーシングに圧入固定するとともに、コイルボビンにコイル端子を押さえてケーシングへの圧入方向と逆方向のコイル端子の移動を規制するリブを設けている。そのため、コイル端子の抜け方向にはコイルボビンのリブが介在することとなり、コイル端子が抜け方向に移動しようとした場合に、コイルボビンのリブによってコイル端子を押さえて移動を規制することができるようになる。よって、従来の接着剤と比べてコイル端子の抜け方向への保持強度を高めることができ、コイル端子の圧入方向と電源コネクタの抜き差し方向とを平行に一致させた場合にもコイル端子を抜け難くすることができる。   According to the present invention, the coil terminal is press-fitted and fixed to the casing of the fixed connector so that the coil terminal is aligned in parallel with the insertion / removal direction of the power connector, and the coil terminal is moved in the direction opposite to the press-fitting direction into the casing by holding the coil terminal on the coil bobbin. The rib which regulates is provided. Therefore, the rib of the coil bobbin is interposed in the coil terminal withdrawal direction, and when the coil terminal is about to move in the withdrawal direction, the coil terminal can be pressed by the coil bobbin rib to restrict the movement. . Therefore, the holding strength in the pulling-out direction of the coil terminal can be increased as compared with the conventional adhesive, and it is difficult to pull out the coil terminal even when the press-fitting direction of the coil terminal and the inserting / removing direction of the power connector are aligned in parallel. can do.

Has been. An opening (not shown) is formed in the upper wall portion 14a, and the end of the coil 11 can be fixed and connected to a connection piece 2b of the coil terminal 2 described later through this opening. .

固定コネクタ３は、電源コネクタ（図示せぬ）が抜き差しされる接続口６が形成されるケーシング４と、このケーシング４に圧入固定されるコイル端子２とを備えている。   The fixed connector 3 includes a casing 4 in which a connection port 6 from which a power connector (not shown) is inserted and removed is formed, and a coil terminal 2 that is press-fitted and fixed to the casing 4.

コイル端子２は、本実施形態では、コイル端子２の一端側（下端側）に設けられてケーシング４に圧入される接続ターミナル２ａと、コイル端子２の他端側（上端側）に設けられてコイル１１の端部が係止される接続片２ｂとを備えている。   In this embodiment, the coil terminal 2 is provided on one end side (lower end side) of the coil terminal 2 and press-fitted into the casing 4, and provided on the other end side (upper end side) of the coil terminal 2. And a connection piece 2b to which the end of the coil 11 is locked.

図２に示すように、本実施形態では、４つ（複数）のコイル端子２が用いられており、この４つのコイル端子２がケーシング４の長手方向（図２の左斜上方向）に並設されている。コイル端子２の接続片２ｂは、接続ターミナル２ａがケーシング４に圧入固定された状態において、ケーシング４の上壁部４ａから上方に突出するようになっている。   As shown in FIG. 2, in this embodiment, four (plural) coil terminals 2 are used, and these four coil terminals 2 are aligned in the longitudinal direction of the casing 4 (upwardly diagonally in FIG. 2). It is installed. The connection piece 2 b of the coil terminal 2 protrudes upward from the upper wall portion 4 a of the casing 4 in a state where the connection terminal 2 a is press-fitted and fixed to the casing 4.

ここで、本実施形態では、電源コネクタ（図示せぬ）の接続口６への抜き差し方向とコイル端子２のケーシング４への圧入方向とを平行に一致させている。具体的には、本実施形態では、これら抜き差し方向と圧入方向とを、コイルボビン１の胴部１２の延在方向となる上下方向（図３の上下方向）に沿って平行に一致させている。   Here, in this embodiment, the insertion / removal direction of the power connector (not shown) to the connection port 6 and the press-fitting direction of the coil terminal 2 to the casing 4 are matched in parallel. Specifically, in this embodiment, these insertion / removal directions and press-fitting directions are made to coincide in parallel along the vertical direction (the vertical direction in FIG. 3) that is the extending direction of the body 12 of the coil bobbin 1.

そして、本実施形態では、コイルボビン１にコイル端子２を押さえてケーシング４への圧入方向と逆方向のコイル端子２の移動を規制するリブ１５を設けている。   In the present embodiment, the coil bobbin 1 is provided with a rib 15 that holds the coil terminal 2 and restricts the movement of the coil terminal 2 in the direction opposite to the press-fitting direction into the casing 4.

具体的には、本実施形態では、コイル端子２をケーシング４の上壁部４ａから下側（接続口６側）に向けて圧入するとともに、そのコイル端子２の圧入方向と電源コネクタ（図示せぬ）の接続口６からの抜き去り方向とが同じになるようにしている。そして、図１（ｂ）に示すように、コイルボビン１のコイル端子収容部１４における開放側の上壁部１４ａ（上壁部１４ａの裏面）に、リブ１５を突設している。したがって、コイルボビン１のリブ１５は、コイル端子２の圧入方向と逆方向となるケーシング４の上側に対向して配置されることになる。   Specifically, in this embodiment, the coil terminal 2 is press-fitted from the upper wall portion 4a of the casing 4 to the lower side (connection port 6 side), and the press-fitting direction of the coil terminal 2 and the power connector (not shown). The removal direction from the connection port 6 is the same. And as shown in FIG.1 (b), the rib 15 is protrudingly provided in the open side upper wall part 14a (the back surface of the upper wall part 14a) in the coil terminal accommodating part 14 of the coil bobbin 1. As shown in FIG. Therefore, the ribs 15 of the coil bobbin 1 are arranged facing the upper side of the casing 4 which is in the direction opposite to the press-fitting direction of the coil terminal 2.

このように、本実施形態では、コイル端子２の抜け方向にリブ１５が設けられたコイルボビン１のコイル端子収容部１４を対向させることで、コイルボビン１全体でコイル端子２を押さえつけることができるようにしている。   Thus, in this embodiment, the coil terminal 2 can be pressed down by the coil bobbin 1 whole by making the coil terminal accommodating part 14 of the coil bobbin 1 in which the rib 15 was provided in the removal direction of the coil terminal 2 face each other. ing.

また、本実施形態では、コイルボビン１と固定コネクタ３とに、これらコイルボビン１と固定コネクタ３とを合体させる係合部７を設けている。そして、図４に示すように、上述したリブ１５は、その係合部７の一方と他方とが係合した状態において、コイル端子２に接触してコイル端子２を押さえつけるようになっている。   Further, in the present embodiment, the coil bobbin 1 and the fixed connector 3 are provided with an engaging portion 7 for combining the coil bobbin 1 and the fixed connector 3. And as shown in FIG. 4, the rib 15 mentioned above contacts the coil terminal 2, and presses the coil terminal 2 in the state which one side and the other of the engaging part 7 engaged.

係合部７は、本実施形態では、固定コネクタ３側のケーシング４に突設された係止爪５と、コイルボビン１側のコイル端子収容部１４に設けられた係止穴１７とで構成されている。そして、係止爪５がケーシング４の長手方向一端部と他端部とに１つずつ設けられているとともに、係止穴１７がそれと対向するコイル端子収容部１４の長手方向一端側の側壁部１４ｂと他端側の側壁部１４ｂとに１つずつ形成されている。   In this embodiment, the engaging portion 7 is constituted by a locking claw 5 protruding from the casing 4 on the fixed connector 3 side and a locking hole 17 provided in the coil terminal accommodating portion 14 on the coil bobbin 1 side. ing. And while the latching claw 5 is provided one each in the longitudinal direction one end part and the other end part of the casing 4, the latching hole 17 is the side wall part of the longitudinal direction one end side of the coil terminal accommodating part 14 which opposes it. 14b and one side wall 14b on the other end side.

このような構成の本実施形態のコイル装置Ｃにあっては、ケーシング４に突設された一対の係止爪５を、コイル端子収容部１４に形成された一対の係止穴１７に係合させることにより、固定コネクタ３とコイルボビン１とが合体して組み付けられる。そして、電源コネクタ（図示せぬ）を固定コネクタ３の接続口６に差し込むことにより、電力がコイル端子２を介してコイル１１に供給されることになる。   In the coil device C of the present embodiment having such a configuration, the pair of locking claws 5 protruding from the casing 4 are engaged with the pair of locking holes 17 formed in the coil terminal accommodating portion 14. By doing so, the fixed connector 3 and the coil bobbin 1 are assembled and assembled. Then, by inserting a power connector (not shown) into the connection port 6 of the fixed connector 3, electric power is supplied to the coil 11 via the coil terminal 2.

このとき、本実施形態では、電源コネクタ（図示せぬ）の接続口６からの抜き去り方向と、コイル端子２のケーシング４への圧入方向とが同じになるようにしている。そのため、電源コネクタ（図示せぬ）の抜き去り時に、コイル端子２が電源コネクタ（図示せぬ）と一緒に引っこ抜かれてしまうのを防止することができる。そして、電源コネクタ（図示せぬ）の差し込み時にコイル端子２が押されて抜けてしまう恐れがあるが、そのコイル端子２の抜け方向にはコイルボビン１のリブ１５と、コイルボビン１と固定コネクタ３とを合体させる係合部７とが対向して配置されている。そのため、コイル端子２の抜け方向への保持強度が高まり、コイル端子２をより抜け難くすることができる。   At this time, in this embodiment, the direction in which the power connector (not shown) is removed from the connection port 6 is the same as the direction in which the coil terminal 2 is pressed into the casing 4. Therefore, when the power connector (not shown) is removed, the coil terminal 2 can be prevented from being pulled out together with the power connector (not shown). The coil terminal 2 may be pushed and pulled out when the power connector (not shown) is inserted, but the coil terminal 2 is pulled out in the direction of removal of the rib 15 of the coil bobbin 1, the coil bobbin 1, and the fixed connector 3. And an engaging portion 7 that unites the two. For this reason, the holding strength in the removal direction of the coil terminal 2 is increased, and the coil terminal 2 can be more difficult to be removed.

以上により、本実施形態では、コイル端子２を電源コネクタ（図示せぬ）の抜き差し方向と平行に一致させて固定コネクタ３のケーシング４に圧入固定している。その一方で、コイルボビン１にコイル端子２を押さえてケーシング４への圧入方向と逆方向のコイル端子２の移動を規制するリブ１５を設けている。そのため、コイル端子２の抜け方向にはコイルボビン１のリブ１５が介在することとなり、コイル端子２が抜け方向に移動しようとした場合に、コイルボビン１のリブ１５によってコイル端子２を押さえて移動を規制することができるようになる。よって、従来の接着剤と比べてコイル端子２の抜け方向への保持強度を高めることができ、コイル端子２の圧入方向と電源コネクタ（図示せぬ）の抜き差し方向とを平行に一致させた場合にもコイル端子２を抜け難くすることができる。   As described above, in this embodiment, the coil terminal 2 is press-fitted and fixed to the casing 4 of the fixed connector 3 so as to coincide with the insertion / removal direction of the power connector (not shown). On the other hand, a rib 15 is provided on the coil bobbin 1 to hold the coil terminal 2 and restrict the movement of the coil terminal 2 in the direction opposite to the press-fitting direction into the casing 4. Therefore, the rib 15 of the coil bobbin 1 is interposed in the direction in which the coil terminal 2 is pulled out. When the coil terminal 2 is about to move in the direction in which the coil terminal 2 is moved, the movement of the coil bobbin 1 is suppressed by pressing the coil terminal 2. Will be able to. Therefore, the holding strength in the pulling-out direction of the coil terminal 2 can be increased as compared with the conventional adhesive, and the press-fitting direction of the coil terminal 2 and the inserting / removing direction of the power connector (not shown) are made to coincide in parallel. In addition, the coil terminal 2 can be made difficult to come off.

また、本実施形態では、電源コネクタ（図示せぬ）の接続口６からの抜き去り方向と、コイル端子２のケーシング４への圧入方向とが同じになるようにしている。そのため、コイル端子２の抜け方向への保持を、リブ１５を含めたコイルボビン１全体で行い易くなり、コイル端子２の保持強度をより高めることができる。すなわち、電源コネクタの抜き方向とコイル端子２の圧入方向とを異ならせた場合には、コイルボビン１が嵩張るため、リブ１５をコイルボビン１から部分的に突設してコイル端子２の抜け方向への保持を、リブ１５単体で行わせなければならない恐れがある。これに対し、本実施形態では、電源コネクタの抜き方向とコイル端子２の圧入方向とを同じにしたので、コイル端子２の抜け方向にリブ１５を含めたコイルボビン１全体を配置し易くでき、コイル端子２の保持をコイルボビン１全体で行い易くすることができる。   In the present embodiment, the direction in which the power connector (not shown) is removed from the connection port 6 is the same as the direction in which the coil terminal 2 is pressed into the casing 4. Therefore, it becomes easy to hold the coil terminal 2 in the removal direction with the entire coil bobbin 1 including the ribs 15, and the holding strength of the coil terminal 2 can be further increased. That is, when the direction in which the power supply connector is pulled out differs from the direction in which the coil terminal 2 is press-fitted, the coil bobbin 1 is bulky, so that the rib 15 is partially protruded from the coil bobbin 1 to the direction in which the coil terminal 2 is pulled out. There is a possibility that the holding must be performed by the rib 15 alone. On the other hand, in this embodiment, since the direction in which the power connector is pulled out is the same as the direction in which the coil terminal 2 is pressed, the entire coil bobbin 1 including the ribs 15 can be easily arranged in the direction in which the coil terminal 2 is pulled out. The terminal 2 can be easily held by the coil bobbin 1 as a whole.

さらにまた、本実施形態では、コイルボビン１と固定コネクタ３とに、これらコイルボビン１と固定コネクタ３とを合体させる係合部７を設けるとともに、リブ１５がその係合部７の係合状態においてコイル端子２に接触して押さえるようにしている。そのため、コイル端子２の抜け方向への移動をリブ１５に加えて係合部７で押さえることができるようになり、コイル端子２の抜け方向への保持強度をより一層高めて、コイル端子２をより抜けに難くすることができる。   Furthermore, in the present embodiment, the coil bobbin 1 and the fixed connector 3 are provided with an engaging portion 7 for combining the coil bobbin 1 and the fixed connector 3, and the rib 15 is coiled in the engaged state of the engaging portion 7. The terminal 2 is touched and pressed. Therefore, the movement of the coil terminal 2 in the pulling direction can be added to the rib 15 and pressed by the engaging portion 7, and the holding strength in the pulling direction of the coil terminal 2 can be further increased, It can be made more difficult to pull out.

以上、本発明の好適な実施形態について説明したが、本発明は上記実施形態には限定されず、種々の変形が可能である。   The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made.

例えば、上記実施形態では、係合部として固定コネクタ側に係止爪を設けるとともに、コイルボビン側に係止穴を設けたものを例示したが、固定コネクタ側に係止穴を設けるとともに、コイルボビン側に係止爪を設けるようにしてもよい。   For example, in the above embodiment, the engaging claw is provided on the fixed connector side as the engaging portion and the engaging hole is provided on the coil bobbin side. However, the engaging hole is provided on the fixed connector side, and the coil bobbin side is provided. You may make it provide a latching claw in this.

また、係合部は、係止爪と係止穴とを係合させる構造に限らず、例えば係止爪を凹部や凸部に係合させる構造など適宜に変更可能である。   Further, the engaging portion is not limited to a structure in which the locking claw and the locking hole are engaged, and for example, a structure in which the locking claw is engaged with the concave portion or the convex portion can be appropriately changed.
