Description

【０００１】
【発明の属する技術分野】
本発明は、冷凍サイクルに使用されるコンデンサのヘッダタンクに、冷媒配管用のコネクタを取り付けるためのコネクタの取付構造に関する。
【０００２】
【従来の技術】
冷凍サイクルに使用され、冷媒を凝縮するためのコンデンサは、通常、冷媒が通るための多数のチューブを並設すると共に、各チューブ間に多数のフィンを接続してコア部を構成し、このコア部の両側に、多数のチューブの両端が接続されるヘッダタンクが取り付けられ、ヘッダタンクには、冷媒配管を接続するためのコネクタが接続固定されて構成される（例えば、下記特許文献１参照）。
【０００３】
【特許文献１】
特開平１１−５４３５号公報
【０００４】
この種のコンデンサは、その製造時、各部品が組み付けられて仮固定された状態で、そのアッセンブリがロウ付け工程に入り、全体の接続部分がロウ付けにより固定されるが、この各部品を仮固定する際、コネクタは、予めヘッダタンクの所定箇所に穿設した開口孔に差し込まれ、爪部をかしめて固定しているため、ヘッダタンクのひずみの発生や作業性の悪さなどの問題が生じていた。
【０００５】
すなわち、従来のコンデンサでは、コネクタをヘッダタンクに仮固定する場合、図６（ａ）のように、予めヘッダタンク２１のコネクタ用の取付部に平坦部２２を設けると共に、その平坦部２２に取付用の開口孔２３を穿設し、その平坦部２２にコネクタ２４の接続孔２４ａを当接させ、コネクタ２４側に設けた爪部２５を開口孔２３の内側に入れた状態で、それをかしめて（曲げて）仮固定している。或いは、図６（ｂ）のように、ヘッダタンク２１の平坦部２２側に設けた爪部２６をコネクタ２４側に接続孔２４ａの内側に入れた状態で、それをかしめて（曲げて）仮固定していた。
【０００６】
【発明が解決しようとする課題】
このため、コネクタ２４を取り付けるために、ヘッダタンク２１の取付部に平坦部２２を形成する必要があり、平坦部を形成できない箇所にはコネクタ２４を接続することができず、設計の自由度が低いという問題があった。また、コネクタ２４側の爪部２５をヘッダタンク２１側の開口孔２３に挿入してかしめる場合には、ヘッダタンクが薄い金属板で成形されているため、爪部をかしめたときにヘッダタンクの金属板にひずみが生じやすく、取付不良を生じる虞があった。また、ヘッダタンク２１側に設けた爪部２６をかしめる場合には、爪部２６がコネクタ２４の接続孔２４ａ内に入るために、かしめ作業の作業性が悪いという問題があった。
【０００７】
本発明は、上述の課題を解決するものであり、コネクタをヘッダタンクの任意の部位に簡単に仮固定することができるコンデンサにおけるコネクタの取付構造を提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記目的を達成するために、本発明のコネクタの取付構造は、コンデンサのコア部の側部に配置されたヘッダタンクに冷媒配管接続用のコネクタを取り付けるためのコネクタの取付構造において、ヘッダタンクの取付部にコネクタ取付用の取付孔が穿設され、取付孔の周縁部には複数の突部が形成され、コネクタの取付部位がその取付孔内に突部を潰しながら圧入して仮固定され、仮固定の接続部分がロウ付けにより固定されたことを特徴とする。
【０００９】
ここで、請求項２のように、上記取付孔の周縁部に設けた突部は、略三角形状に形成するとよい。また、請求項３のように、突部の大きさは、コネクタの圧入時に変形可能で、且つ圧入により接続部位に生じた隙間がロウ付けにより埋まる程度に微細に形成するとよい。
【００１０】
【作用】
上記構成のコネクタの取付構造では、ヘッダタンクの所定位置に予めコネクタの取付部に対応した大きさの取付孔が穿設され、その取付孔の周縁部には複数の突部が形成される。コンデンサの各部を仮固定する際、コネクタは、その取付部をヘッダタンクの取付孔に圧入して行なう。このとき、コネクタの取付部の圧入により、ヘッダタンク側の取付孔の周縁部に設けた複数の突部は潰され、コネクタの取付部はそのヘッダタンクの取付孔内に確実に仮固定される。
【００１１】
したがって、このような仮固定時、従来のように爪部をかしめる工程は不要となるから、薄い金属板製のヘッダタンクの取付孔周縁にひずみが生じることはなく、コネクタの圧入により良好且つ簡単に仮固定することができる。さらに、コネクタの取付部には、従来のような平坦部を設ける必要がないから、コネクタ用の取付孔は、ヘッダタンクの任意の場所に設けることができ、コンデンサの設計の自由度が向上するという利点がある。仮固定されたコンデンサアッセンブリは、その後、ロウ付け工程に入り、全ての接続部がロウ付けされる。
【００１２】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図１は車載用の冷凍サイクルに使用されるコンデンサ１の正面図を示し、図２はそのヘッダタンク６に接続固定されたコネクタ１０の拡大断面図を示している。
【００１３】
コンデンサ１は、水平方向に並設された多数のチューブ３と各チューブ３間に配置した多数のフィン４とを備えたコア部２と、コア部２の両側に配置され各チューブ３の両端が接続されるヘッダタンク６，７と、ヘッダタンク６の側部に並設されたモジュレータタンク８と、を有して構成される。左側のヘッダタンク６の上部には、冷媒導入用の冷媒配管を接続するためのコネクタ１０が、後述のように、その取付部１１を圧入して仮固定した状態で、ロウ付けにより固定される。
【００１４】
さらに、ヘッダタンク６内及びヘッダタンク７内には、コネクタ１０から導入した冷媒をチューブ３の方向に方向転換させて流すためのセパレータ６１，７１がタンク内を短手方向に仕切るように複数枚配設される。また、右側のヘッダタンク７の下部には、冷媒を送出するための冷媒配管が接続される送出用コネクタ９が接続固定され、左側のヘッダタンク６の上部のコネクタ１０から導入された冷媒が、両側のヘッダタンク６，７とその間の多数のチューブ３間を方向転換しながら蛇行して流れ、その後、右側のヘッダタンク７の下部に設けた送出用コネクタ９から送出されるように構成される。
【００１５】
一方のヘッダタンク６に接続されるモジュレータタンク８は、ヘッダタンク６を流れる液冷媒を回収して貯留し、過冷却を行なうもので、モジュレータタンク８とヘッダタンク６とは接続部に設けた連通孔を介して接続されている。また、モジュレータタンク８内には乾燥剤が充填される。
【００１６】
このような構成のコンデンサ１は、上記ヘッダタンク６，７、チューブ３などの各部材が例えば金属板の両面にロウ材を塗布したクラッド材を使用して形成され、製造段階で、コンデンサ１を組み立てる場合は、まず、各部品を適正に組み付けて仮固定し、その後、ロウ付け工程を実施し、仮固定したアッセンブリをロウ付け炉に入れて加熱し、全ての接続箇所をロウ付けにより一度に固定する。
【００１７】
このために、各チューブ３の両端部が両側のヘッダタンク６，７の側部に設けた開口部に差し込まれて仮固定されるなど、コンデンサの各部材は適正な状態に組み付けられて仮固定されるが、コネクタ１０についても、図２に示すように、ヘッダタンク６の正面側に形成された取付孔６２に、コネクタ１０の取付部１１を差し込むように圧入して仮固定される。
【００１８】
このようなコネクタ１０の圧入による仮固定を良好に行なうために、ヘッダタンク６に形成した取付孔６２の周縁部には、図４に示すように、複数の微細な突部６３が形成されている。取付孔６２は、図４に示す如く、コネクタ１０の取付部１１を密に差し込み可能な形状に、つまり取付部１１の正面視と同じ形状に形成され、その取付孔６２の周縁部に、複数の突部６３が、コネクタ１０の取付部１１の圧入時に押し潰し可能に形成される。これらの突部６３は、図４のように、略三角形状に形成され、その高さ及び幅は約０．５ｍｍと微細に形成される。つまり、突部６３の大きさは、コネクタ１０の圧入時に変形可能で、且つ圧入により取付孔６２の周縁の取付部位に生じた隙間が、ロウ付けの際のロウにより埋まる程度に小さく設定されている。
【００１９】
コンデンサ１の製造時、各部品を組み付けて仮固定する場合、治具や自動組立装置を使用して自動的に、或いは作業者の手作業により、組み付け作業が行なわれるが、コネクタ１０を組み付ける際には、図５に示すように、コネクタ１０の取付部１１をヘッダタンク６の取付孔６２に差し込み、圧入する。このとき、取付孔６２の周縁部の微細な突部６３は潰され、コネクタ１０の取付部１１の外側面は取付孔６２の周縁部に密に保持される。
【００２０】
したがって、コネクタ１０を取付孔６２に差し込み圧入するだけで簡単に、所定の位置に適正な状態でコネクタ１０を仮固定することができる。また、圧入によりコネクタ１０を組み付けるため、従来のようにヘッダタンクの取付孔の上に平坦部を形成する必要がなく、平坦部を形成できない箇所であっても、コネクタ１０を取り付けることができ、また、従来のように爪部をかしめる工程は不要となり、薄い金属板製のヘッダタンクの取付孔周縁にひずみが生じることもなくなる。
【００２１】
そして、各部品を適正に組み付けて仮固定されたコンデンサアッセンブリは、その後、ロウ付け工程に入り、ロウ付け炉に搬入されて加熱され、全ての接続箇所がロウ付けにより一度に固定される。
【００２２】
このように製造されたコンデンサ１は、車載用の冷凍サイクルで使用され、その冷媒導入側のコネクタ１０には、図示しないコンプレッサの吐出側の冷媒配管が接続され、その送出側コネクタ９には、図示しない膨張弁に通ずる冷媒配管が接続される。
【００２３】
コンプレッサによって加圧され凝縮された高圧冷媒は、コンデンサ１のコネクタ１０からヘッダタンク６に導入され、左側のヘッダタンク６からチューブ３を通り右側のヘッダタンク７に入り、そこで方向転換してチューブ３を逆方向に通過して左側のヘッダタンク６に入るように流れる。このとき、コア部２に向かって流れる外気に対し熱交換が行なわれ、高温高圧の冷媒の凝縮熱が外気に奪われ冷媒が冷却されることにより、冷媒は液化され、送出側のコネクタ９を通して膨張弁に送出される。そして、膨張弁を通過して気化したガス冷媒は、エバポレータに送られ、空調用の空気との間で熱交換が行なわれることになる。
【００２４】
なお、上記実施形態では、導入側のコネクタ１０をヘッダタンク６に仮固定する場合について圧入により仮固定したが、送出用コネクタ９をヘッダタンク７に仮固定する場合にも、同様に圧入を用いて仮固定することができる。
【００２５】
【発明の効果】
以上説明したように、本発明のコンデンサにおけるコネクタの取付構造によれば、ヘッダタンクの取付孔へコネクタを圧入して仮固定するから、従来のように爪部をかしめる工程は不要となり、薄い金属板製のヘッダタンクの取付孔周縁にひずみが生じることはなく、コネクタの圧入により確実に且つ簡単に仮固定することができる。さらに、コネクタの取付部には、従来のような平坦部を設ける必要がないから、コネクタ用の取付孔は、ヘッダタンクの任意の場所に設けることができ、コンデンサの設計の自由度が向上するという利点がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connector mounting structure for mounting a connector for refrigerant piping to a header tank of a condenser used in a refrigeration cycle.
[0002]
[Prior art]
A condenser for condensing refrigerant, which is used in a refrigeration cycle, usually has a number of tubes arranged in parallel with the refrigerant, and a number of fins connected between the tubes to form a core portion. A header tank to which both ends of a large number of tubes are connected is attached to both sides of the portion, and a connector for connecting a refrigerant pipe is connected and fixed to the header tank (for example, see Patent Document 1 below). .
[0003]
[Patent Document 1]
JP-A-11-5435
In this type of capacitor, when the components are assembled and temporarily fixed at the time of manufacture, the assembly enters a brazing process, and the entire connection portion is fixed by brazing. At the time of fixing, the connector is inserted into an opening hole drilled at a predetermined location of the header tank in advance, and the claw part is caulked and fixed, causing problems such as distortion of the header tank and poor workability. I was
[0005]
That is, in the conventional capacitor, when the connector is temporarily fixed to the header tank, as shown in FIG. 6A, a flat portion 22 is provided in advance in the connector mounting portion of the header tank 21 and the flat portion 22 is mounted on the flat portion 22. A hole 24 for the connector 24 is drilled, the connection hole 24a of the connector 24 is brought into contact with the flat portion 22, and the claw 25 provided on the connector 24 side is inserted into the inside of the hole 23, and then it is removed. It is temporarily fixed (bent). Alternatively, as shown in FIG. 6B, with the claw portion 26 provided on the flat portion 22 side of the header tank 21 inserted into the connection hole 24a on the connector 24 side, it is temporarily crimped (bent). It was fixed.
[0006]
[Problems to be solved by the invention]
For this reason, in order to attach the connector 24, it is necessary to form the flat portion 22 in the mounting portion of the header tank 21, and the connector 24 cannot be connected to a portion where the flat portion cannot be formed, and the degree of freedom of design is increased. There was a problem of low. When the claw 25 of the connector 24 is inserted into the opening hole 23 of the header tank 21 and swaged, the header tank is formed of a thin metal plate. In this case, the metal plate tends to be distorted, and there is a possibility that mounting failure may occur. Further, when the claw portion 26 provided on the header tank 21 side is swaged, the claw portion 26 enters the connection hole 24a of the connector 24, so that the workability of the swaging operation is poor.
[0007]
An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a mounting structure of a connector in a capacitor which can easily temporarily fix the connector to an arbitrary portion of a header tank.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the connector mounting structure of the present invention is a connector mounting structure for mounting a refrigerant pipe connection connector to a header tank arranged on a side of a core part of a capacitor, A mounting hole for mounting a connector is formed in the mounting portion, and a plurality of protrusions are formed at a peripheral portion of the mounting hole. , Characterized in that the temporarily fixed connection part is fixed by brazing.
[0009]
Here, as in claim 2, the projection provided on the peripheral edge of the mounting hole may be formed in a substantially triangular shape. Further, as in the third aspect, the size of the protrusion is preferably small enough to be deformable at the time of press-fitting of the connector and to fill a gap created at the connection site by press-fitting by brazing.
[0010]
[Action]
In the connector mounting structure having the above-described configuration, a mounting hole having a size corresponding to the mounting portion of the connector is formed in advance at a predetermined position of the header tank, and a plurality of protrusions are formed on the periphery of the mounting hole. When temporarily fixing each part of the capacitor, the connector presses the mounting part into the mounting hole of the header tank. At this time, the plurality of protrusions provided on the peripheral edge of the mounting hole on the header tank side are crushed by press-fitting of the mounting portion of the connector, and the mounting portion of the connector is securely temporarily fixed in the mounting hole of the header tank. .
[0011]
Therefore, at the time of such temporary fixing, the step of caulking the claws is not necessary as in the prior art, so that no distortion occurs at the periphery of the mounting hole of the header tank made of a thin metal plate. It can be easily temporarily fixed. Furthermore, since it is not necessary to provide a flat portion in the connector mounting portion as in the related art, the mounting hole for the connector can be provided at an arbitrary position in the header tank, and the degree of freedom in designing the capacitor is improved. There is an advantage. The temporarily fixed capacitor assembly then enters a brazing step, in which all connections are brazed.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a condenser 1 used in a vehicle-mounted refrigeration cycle, and FIG. 2 is an enlarged sectional view of a connector 10 fixedly connected to a header tank 6.
[0013]
The condenser 1 includes a core portion 2 having a large number of tubes 3 arranged in a horizontal direction and a large number of fins 4 arranged between the tubes 3, and both ends of each tube 3 arranged on both sides of the core portion 2. It is configured to include header tanks 6 and 7 to be connected and a modulator tank 8 arranged side by side with the header tank 6. A connector 10 for connecting a refrigerant pipe for introducing a refrigerant is fixed to the upper part of the left header tank 6 by brazing in a state where the mounting portion 11 is press-fitted and temporarily fixed as described later. .
[0014]
Further, in the header tank 6 and the header tank 7, a plurality of separators 61 and 71 for turning the refrigerant introduced from the connector 10 in the direction of the tube 3 and flowing the same so as to partition the tank in the transverse direction are provided. Will be arranged. Further, a delivery connector 9 to which a coolant pipe for delivering a coolant is connected is fixed to a lower portion of the right header tank 7, and a coolant introduced from a connector 10 at an upper portion of the left header tank 6 is It flows in a meandering manner while changing the direction between the header tanks 6 and 7 on both sides and a large number of tubes 3 between them, and is then delivered from a delivery connector 9 provided below the header tank 7 on the right. .
[0015]
The modulator tank 8 connected to one of the header tanks 6 recovers and stores the liquid refrigerant flowing through the header tank 6 and performs supercooling. The modulator tank 8 and the header tank 6 communicate with each other at a communication portion provided at a connection portion. They are connected through holes. The modulator tank 8 is filled with a desiccant.
[0016]
In the capacitor 1 having such a configuration, the respective members such as the header tanks 6 and 7 and the tube 3 are formed using a clad material in which a brazing material is applied to both surfaces of a metal plate, for example. When assembling, first properly assemble each part and temporarily fix it, then carry out a brazing process, put the temporarily fixed assembly in a brazing furnace and heat it, and braze all the connection points at once Fix it.
[0017]
For this purpose, the components of the capacitor are assembled in an appropriate state and temporarily fixed, for example, both ends of each tube 3 are inserted into openings provided on both sides of the header tanks 6 and 7 and temporarily fixed. However, as shown in FIG. 2, the connector 10 is also press-fitted so as to insert the mounting portion 11 of the connector 10 into a mounting hole 62 formed on the front side of the header tank 6 and temporarily fixed.
[0018]
As shown in FIG. 4, a plurality of fine protrusions 63 are formed on the peripheral edge of the mounting hole 62 formed in the header tank 6 in order to perform the temporary fixing by press-fitting the connector 10 well. I have. As shown in FIG. 4, the mounting hole 62 is formed in a shape into which the mounting portion 11 of the connector 10 can be densely inserted, that is, in the same shape as the mounting portion 11 when viewed from the front. Is formed so as to be crushable when the mounting portion 11 of the connector 10 is press-fitted. These protruding portions 63 are formed in a substantially triangular shape as shown in FIG. 4, and the height and width thereof are minutely formed to be about 0.5 mm. That is, the size of the protrusion 63 is set to be small enough to be deformable when the connector 10 is press-fitted, and to fill the gap created in the mounting portion of the mounting hole 62 by press-fitting with the brazing at the time of brazing. I have.
[0019]
At the time of manufacturing the capacitor 1, when assembling and temporarily fixing the components, the assembling work is performed automatically using a jig or an automatic assembling apparatus or manually by an operator. 5, the mounting portion 11 of the connector 10 is inserted into the mounting hole 62 of the header tank 6 and press-fitted. At this time, the fine protrusion 63 on the peripheral edge of the mounting hole 62 is crushed, and the outer surface of the mounting portion 11 of the connector 10 is densely held by the peripheral edge of the mounting hole 62.
[0020]
Therefore, the connector 10 can be temporarily fixed in a predetermined position in an appropriate state simply by inserting the connector 10 into the mounting hole 62 and press-fitting it. Further, since the connector 10 is assembled by press-fitting, it is not necessary to form a flat portion on the mounting hole of the header tank as in the related art, and the connector 10 can be mounted even in a place where the flat portion cannot be formed, Further, the step of caulking the claws as in the prior art is not required, and the peripheral edge of the mounting hole of the header tank made of a thin metal plate is not distorted.
[0021]
Then, the capacitor assembly temporarily assembled by appropriately assembling the components enters a brazing step, is carried into a brazing furnace, is heated, and is fixed at once by brazing.
[0022]
The condenser 1 manufactured in this manner is used in an on-board refrigeration cycle, and a refrigerant pipe on a discharge side of a compressor (not shown) is connected to a connector 10 on a refrigerant introduction side thereof. A refrigerant pipe leading to an expansion valve (not shown) is connected.
[0023]
The high-pressure refrigerant pressurized and condensed by the compressor is introduced from the connector 10 of the condenser 1 into the header tank 6, passes from the left header tank 6 through the tube 3 and enters the right header tank 7, where it is turned to the tube 3. Flows in the opposite direction to enter the header tank 6 on the left side. At this time, heat is exchanged with the outside air flowing toward the core portion 2, the condensation heat of the high-temperature and high-pressure refrigerant is taken away by the outside air, and the refrigerant is cooled, so that the refrigerant is liquefied and passed through the connector 9 on the sending side. Delivered to the expansion valve. The gas refrigerant that has passed through the expansion valve and vaporized is sent to the evaporator, where heat exchange is performed with air for air conditioning.
[0024]
In the above-described embodiment, the connector 10 on the introduction side is temporarily fixed to the header tank 6 by press-fitting. However, when the connector 9 for transmission is temporarily fixed to the header tank 7, the press-fitting is similarly performed. Can be temporarily fixed.
[0025]
【The invention's effect】
As described above, according to the mounting structure of the connector in the capacitor of the present invention, since the connector is press-fitted into the mounting hole of the header tank and temporarily fixed, the step of caulking the claw portion as in the related art is unnecessary, and it is thin. There is no distortion in the periphery of the mounting hole of the metal plate header tank, and the temporary fixing can be reliably and easily performed by press-fitting the connector. Further, since there is no need to provide a flat portion in the connector mounting portion as in the related art, the mounting hole for the connector can be provided at any location in the header tank, and the degree of freedom in designing the capacitor is improved. There is an advantage.
