そして、図５に示すように第１・第２コネクタ６１，６２をサイドプレート５４の第１・第２の接続口６３，６４に取り付ける際に、第２のコネクタのフランジ部６６の位置決め部６６ａに第１のコネクタ６１を仮保持しつつ、第１のコネクタのフランジ部６５または第２のコネクタのフランジ部６６のうち一方のフランジ部（つまり本実施形態では第２のコネクタのフランジ部６６）を、他方のフランジ部（つまり本実施形態では第１のコネクタのフランジ部６５）とサイドプレート５４との間に挟持するようになっている。   Then, as shown in FIG. 5, when the first and second connectors 61 and 62 are attached to the first and second connection ports 63 and 64 of the side plate 54, the positioning portions 66a of the flange portion 66 of the second connector. While temporarily holding the first connector 61, one flange portion of the flange portion 65 of the first connector or the flange portion 66 of the second connector (that is, the flange portion 66 of the second connector in this embodiment). Is sandwiched between the other flange portion (that is, the flange portion 65 of the first connector in this embodiment) and the side plate 54.

従って、第１・第２のコネクタ６１，６２は、第１のコネクタ６１が第２のコネクタのフランジ部６６に仮保持されつつ、それぞれの接続固定部６１ａ，６２ａが第１・第２の接続口６３，６４に差し込まれることにより、サイドプレート５４に仮固定され、この状態で上記接続固定部６１ａ，６２ａと第１・第２の接続口６３，６４との間、およびコネクタ６１、６２同士の間がロー付けされることにより、第１・第２のコネクタ６１，６２がサイドプレート５４に本固定される。   Therefore, the first and second connectors 61 and 62 are temporarily held by the flange portion 66 of the second connector, and the connection fixing portions 61a and 62a are respectively connected to the first and second connections. By being inserted into the ports 63 and 64, it is temporarily fixed to the side plate 54. In this state, between the connection fixing portions 61a and 62a and the first and second connection ports 63 and 64, and between the connectors 61 and 62 The first and second connectors 61 and 62 are permanently fixed to the side plate 54 by being brazed.

ところで、第１・第２のコネクタ６１，６２は、それぞれの内部に冷媒を流通する中空部６１ｄ，６２ｄが形成され、第１のコネクタ６１の中空部６１ｄは直線状に形成されるが、第２のコネクタ６２の中空部６２ｄは、接続固定部６２ａ側の中空部６２ｄ′と配管接続部６２ｂ側の中空部６２ｄ″とで中心軸Ｃ１，Ｃ２が相互にオフセットされている。   By the way, the first and second connectors 61 and 62 are formed with hollow portions 61d and 62d through which refrigerant flows, respectively, and the hollow portion 61d of the first connector 61 is formed linearly. In the hollow portion 62d of the second connector 62, the central axes C1 and C2 are offset from each other by the hollow portion 62d ′ on the connection fixing portion 62a side and the hollow portion 62d ″ on the pipe connection portion 62b side.

以上の構成により本実施形態によれば、第１のコネクタ６１と第２のコネクタ６２とを互いに独立形成し、それら第１・第２のコネクタ６１，６２を、第２のコネクタ６２から突設した第２のコネクタのフランジ部６６に形成した位置決め部６６ａに第１のコネクタ６１を仮保持させて合体したので、第１のコネクタ６１と第２のコネクタ６２との間の間隔をより狭くして、配管コネクタ６０の小型化を達成することができる。   With the above configuration, according to the present embodiment, the first connector 61 and the second connector 62 are formed independently from each other, and the first and second connectors 61 and 62 project from the second connector 62. Since the first connector 61 is temporarily held and combined with the positioning portion 66a formed on the flange portion 66 of the second connector, the interval between the first connector 61 and the second connector 62 is made narrower. Thus, the piping connector 60 can be reduced in size.

また、このように位置決め部６６ａで第１のコネクタ６１を仮保持しつつ、第２のコネクタのフランジ部６６を、第１のコネクタのフランジ部６５とサイドプレート５４との間で挟持し、それぞれのコネクタ６１，６２の接続固定部６１ａ，６２ａを第１・第２の接続口６３，６４に差し込むことにより、双方のコネクタ６１，６２を熱交換器１に仮固定することができ、この状態で第１・第２のコネクタ６１，６２と第１・第２の接続口６３，６４との間と、仮保持した第２のコネクタのフランジ部６６の位置決め部６６ａと第１のコネクタ６１との間と、をロー付けすることにより、第１・第２のコネクタ６１，６２を熱交換器に本固定することができる。このとき、第２のコネクタのフランジ部６６の位置決め部６６ａには第１のコネクタ６１を単に仮保持すれば良いため、第１のコネクタ６１と第２のコネクタ６２の合体構造を簡素化でき、かつ、その位置決め部６６ａの寸法精度を落とすことが可能となるため、配管コネクタ６０の製造コストを低下することができる。   In addition, the first connector 61 is temporarily held by the positioning portion 66a in this way, and the flange portion 66 of the second connector is sandwiched between the flange portion 65 of the first connector and the side plate 54, respectively. By inserting the connection fixing portions 61a and 62a of the connectors 61 and 62 into the first and second connection ports 63 and 64, both the connectors 61 and 62 can be temporarily fixed to the heat exchanger 1, and in this state The first and second connectors 61 and 62 and the first and second connection ports 63 and 64, the positioning portion 66a of the temporarily held flange portion 66 of the second connector, and the first connector 61 The first and second connectors 61 and 62 can be permanently fixed to the heat exchanger. At this time, it is only necessary to temporarily hold the first connector 61 in the positioning portion 66a of the flange portion 66 of the second connector, so that the combined structure of the first connector 61 and the second connector 62 can be simplified. And since it becomes possible to reduce the dimensional accuracy of the positioning part 66a, the manufacturing cost of the piping connector 60 can be reduced.

更に、本実施形態では位置決め部６６ａをＵ字状に切欠部として構成したため、その位置決め部６６ａに第１のコネクタ６１を嵌合する際に、第１のコネクタ６１の側方から位置決め部６６ａを差し込むようにして嵌合できるので、第１のコネクタ６１と位置決め部６６ａとの組み付けをより簡単にできる。   Further, in the present embodiment, the positioning portion 66a is configured as a U-shaped cutout portion. Therefore, when the first connector 61 is fitted into the positioning portion 66a, the positioning portion 66a is formed from the side of the first connector 61. Since it can be fitted so as to be inserted, the first connector 61 and the positioning portion 66a can be assembled more easily.

（第２実施形態）
図８〜図１０は本発明の第２実施形態を示し、上述の第１実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べるものとし、図８は配管コネクタの取付状態を示す断面図、図９は第２のコネクタの正面図、図１０は図９中Ｄ−Ｄ線に沿った断面図である。 (Second Embodiment)
8 to 10 show a second embodiment of the present invention, in which the same reference numerals are given to the same components as those in the first embodiment described above, and a duplicate description is omitted, and FIG. FIG. 9 is a front view of the second connector, and FIG. 10 is a sectional view taken along line DD in FIG.

本実施形態が第１実施形態と特に異なる点は、、第１のコネクタのフランジ部６５が、第２のコネクタのフランジ部６６とサイドプレート５４との間に挟持されていることである。   This embodiment is particularly different from the first embodiment in that the flange portion 65 of the first connector is sandwiched between the flange portion 66 of the second connector and the side plate 54.

また、位置決め部６６ｃは図９に示すように円形状に形成される点で、位置決め部６６ａがＵ字状に形成される第１実施形態と異なっている。位置決め部６６ｃのサイドプレート５４側の周縁部には、図１０に示すように第１のコネクタのフランジ部６５を嵌合する段差部６６ｄが形成されている。   Further, the positioning portion 66c is different from the first embodiment in which the positioning portion 66a is formed in a U shape in that it is formed in a circular shape as shown in FIG. As shown in FIG. 10, a stepped portion 66d for fitting the flange portion 65 of the first connector is formed on the peripheral portion of the positioning portion 66c on the side plate 54 side.

従って、本実施形態によれば、第１実施形態とは逆に第１のコネクタのフランジ部６５が、第２のコネクタのフランジ部６６とサイドプレート５４との間に挟持されるようになっているが、この場合にあっても第１実施形態と同様に第１・第２のコネクタ６１，６２を熱交換器１に確実に仮固定することができ、その後、ロー付けにより本固定することができる。   Therefore, according to this embodiment, contrary to the first embodiment, the flange portion 65 of the first connector is sandwiched between the flange portion 66 of the second connector and the side plate 54. However, even in this case, the first and second connectors 61 and 62 can be securely fixed to the heat exchanger 1 as in the first embodiment, and then fixed by brazing. Can do.

また、本実施形態では位置決め部６６ｃは円形状に形成して、これに第１のコネクタ６１を仮保持することになるが、この場合にあっても位置決め部６６ｃはあくまでも第１のコネクタ６１を位置決めして仮保持すればよいため、その位置決め部６６ｃの寸法精度を落として配管コネクタ６０Ａの製造コストを低減できる。   In this embodiment, the positioning portion 66c is formed in a circular shape, and the first connector 61 is temporarily held by the positioning portion 66c. However, even in this case, the positioning portion 66c is not limited to the first connector 61. Since positioning and temporary holding are sufficient, the dimensional accuracy of the positioning portion 66c can be lowered, and the manufacturing cost of the pipe connector 60A can be reduced.

（第３実施形態）
図１１〜図１４は本発明の第３実施形態を示し、前記各実施形態と同一構成部分に同一符号を付して重複する説明を省略して述べるものとする。図１１は第３実施形態の配管コネクタの取付状態を示す断面図、図１２は同配管コネクタの第２のコネクタの正面図、図１３は図９中Ｅ−Ｅ線に沿った断面図、図１４は配管コネクタの組付前を示す断面図である。 (Third embodiment)
11 to 14 show a third embodiment of the present invention, in which the same components as those of the above-described embodiments are denoted by the same reference numerals and redundant description is omitted. 11 is a cross-sectional view showing a mounting state of the pipe connector of the third embodiment, FIG. 12 is a front view of the second connector of the pipe connector, and FIG. 13 is a cross-sectional view taken along line EE in FIG. 14 is a cross-sectional view showing the pipe connector before assembly.

本第３実施形態の配管コネクタ６０Ｂは、基本的に第１実施形態の配管コネクタ６０と略同様の構成となり、図１１に示すように第１のコネクタ６１の外周からフランジ部６５が突設されるとともに、第２のコネクタ６２の外周からフランジ部６６が突設され、その第２のコネクタのフランジ部６６に第１のコネクタ６１を仮保持するＵ字状の位置決め部６６ａが形成されている。   The piping connector 60B according to the third embodiment basically has the same configuration as the piping connector 60 according to the first embodiment, and a flange portion 65 projects from the outer periphery of the first connector 61 as shown in FIG. In addition, a flange portion 66 projects from the outer periphery of the second connector 62, and a U-shaped positioning portion 66a for temporarily holding the first connector 61 is formed on the flange portion 66 of the second connector. .

また、第１・第２のコネクタ６１，６２を熱交換器１に仮固定する際に、第２実施形態と同様に第１のコネクタのフランジ部６５が、第２のコネクタのフランジ部６６とサイドプレート５４との間に挟持されるようになっている。   Further, when the first and second connectors 61 and 62 are temporarily fixed to the heat exchanger 1, the flange portion 65 of the first connector is connected to the flange portion 66 of the second connector in the same manner as in the second embodiment. It is sandwiched between the side plate 54.

本実施形態が第１・第２実施形態と特に異なる点は、前記一方のフランジ部、つまり、相互に重ね合わされるフランジ部６５、６６のうち、サイドプレート５４に近い側のフランジ部６６に、サイドプレート５４に当接する脚部６７が設けられていることにある。   This embodiment is particularly different from the first and second embodiments in the one flange portion, that is, the flange portion 66 on the side close to the side plate 54 among the flange portions 65 and 66 that are overlapped with each other. A leg portion 67 that abuts against the side plate 54 is provided.

この脚部６７は、図１２に示すようにフランジ部６６のサイドプレート５４に対向する面に、第２のコネクタ６２の接続固定部６２ａを中心として位置決め部６６ａとは反対側を略半円状に囲繞して設けられるとともに、その位置決め部６６ａの両側先端部に設けられる。   As shown in FIG. 12, the leg portion 67 has a substantially semicircular shape opposite to the positioning portion 66a around the connection fixing portion 62a of the second connector 62 on the surface facing the side plate 54 of the flange portion 66. And is provided at both ends of the positioning portion 66a.

図１３に示すように接続固定部６２ａに最も近い略半円状の脚部６７と第２の接続口６４（第２のコネクタ６２の接続固定部６２ａ）との間には所定間隔Ｓが設けられ、また図１２に示すように位置決め部６６ａの両側先端部の脚部６７と第１の接続口６３との間に所定間隔Ｓが設けられている。   As shown in FIG. 13, a predetermined interval S is provided between the substantially semicircular leg portion 67 closest to the connection fixing portion 62a and the second connection port 64 (connection fixing portion 62a of the second connector 62). In addition, as shown in FIG. 12, a predetermined interval S is provided between the leg portion 67 at the distal end on both sides of the positioning portion 66 a and the first connection port 63.

また、図１１に示すように脚部６７の高さＨ１は、接続口６４の高さＨ２よりも大きく（Ｈ１＞Ｈ２）なっており、第２のコネクタ６２を接続口６４に差し込んだ際に脚部６７が確実に第２のコネクタのフランジ部６６の面に当接するようになっている。   Further, as shown in FIG. 11, the height H1 of the leg portion 67 is larger than the height H2 of the connection port 64 (H1> H2), and when the second connector 62 is inserted into the connection port 64, The leg portion 67 is surely brought into contact with the surface of the flange portion 66 of the second connector.

更に、第１のコネクタ６１は、第２のコネクタのフランジ部６６に形成した位置決め部６６ａに単に位置決めされて仮保持されれば足りるため、それら両者間に高い寸法精度が要求されないことから、本実施形態ではその第１のコネクタ６１が管材を転造して、第１のコネクタのフランジ部６５、接続固定部６１ａ、配管接続部６１ｂおよび周溝６１ｃが形出されるようになっている。   Furthermore, since the first connector 61 need only be positioned and temporarily held by the positioning portion 66a formed on the flange portion 66 of the second connector, high dimensional accuracy is not required between them. In the embodiment, the first connector 61 rolls the pipe material, and the flange portion 65, the connection fixing portion 61a, the pipe connection portion 61b, and the circumferential groove 61c of the first connector are formed.

そして、本実施形態にあっても第１・第２のコネクタ６１，６２は、第１のコネクタ６１が第２のコネクタのフランジ部６６の位置決め部６６ａに仮保持されつつ、それぞれの接続固定部６１ａ，６２ａが第１・第２の接続口６３，６４に差し込まれてサイドプレート５４に仮固定される。   Even in the present embodiment, the first and second connectors 61 and 62 are connected to each of the connection fixing portions while the first connector 61 is temporarily held by the positioning portion 66a of the flange portion 66 of the second connector. 61 a and 62 a are inserted into the first and second connection ports 63 and 64 and temporarily fixed to the side plate 54.

このとき、本実施形態では図１１に示すように前記他方のフランジ部、つまり相互に重ね合わされる第１のコネクタのフランジ部６５または第２のコネクタのフランジ部６６のうち、サイドプレート５４から遠い側に配置されるフランジ部６５を形成したコネクタ（つまり第１のコネクタ６１）を第１の接続口６３に接続した状態で、その一方（この例ではコネクタ６１の接続固定部６１ａの先端６８）が加締められることで、コネクタ６１、６２が熱交換器本体１ａに仮固定されている。   At this time, in the present embodiment, as shown in FIG. 11, the other flange portion, that is, the flange portion 65 of the first connector or the flange portion 66 of the second connector that is overlapped with each other, is far from the side plate 54. In a state where the connector (that is, the first connector 61) having the flange portion 65 disposed on the side is connected to the first connection port 63, one of them (in this example, the distal end 68 of the connection fixing portion 61a of the connector 61). The connectors 61 and 62 are temporarily fixed to the heat exchanger main body 1a.

上記加締めは、第１の接続口６３に第１のコネクタ６１の接続固定部６１ａを差し込んだ状態で、図１１に示すようにポンチＴをその接続固定部６１ａの先端開口から打ち込んでその先端開口部分を拡開させるようになっている。   The caulking is performed in a state where the connection fixing portion 61a of the first connector 61 is inserted into the first connection port 63, as shown in FIG. 11, by driving the punch T from the front end opening of the connection fixing portion 61a. The opening is expanded.

従って、本実施形態によれば、第１・第２のコネクタ６１，６２をそれぞれの第１・第２のコネクタのフランジ部６５，６６を相互に重ね合わせて熱交換器１に仮固定する際に、サイドプレート５４から遠い側に配置されるフランジ部６５を形成した第１のコネクタ６１を第１の接続口６３に接続した状態で、その一方（この例ではコネクタ６１の接続固定部６１ａの先端６８）を加締めるようにしたので、第１のコネクタのフランジ部６５で第２のコネクタのフランジ部６６を押さえた状態で第１・第２のコネクタ６１，６２を仮固定できる。そのため、これら第１・第２のコネクタ６１，６２の仮固定状態をより安定化でき、ひいては、ロー付け精度をより向上できる。   Therefore, according to the present embodiment, when the first and second connectors 61 and 62 are temporarily fixed to the heat exchanger 1 by overlapping the flange portions 65 and 66 of the first and second connectors with each other. In the state where the first connector 61 formed with the flange portion 65 disposed on the side far from the side plate 54 is connected to the first connection port 63, one of them (in this example, the connection fixing portion 61a of the connector 61). Since the tip 68) is crimped, the first and second connectors 61 and 62 can be temporarily fixed while the flange portion 65 of the second connector is pressed by the flange portion 65 of the first connector. Therefore, the temporarily fixed state of these first and second connectors 61 and 62 can be further stabilized, and as a result, the brazing accuracy can be further improved.

また、相互に重ね合わされるフランジ部６５またはフランジ部６６のうちサイドプレート５４に近い側に配置されるフランジ部６６に設けた脚部６７によって、そのフランジ部６６をサイドプレート５４に安定して当接させることができるため、第１・第２のコネクタ６１，６２の仮固定状態をより安定化させ、ひいては、ロー付けにより第１・第２のコネクタ６１，６２を本固定した時の精度をより向上できる。   Further, the flange portion 66 provided on the flange portion 66 disposed on the side close to the side plate 54 of the flange portion 65 or the flange portion 66 that is overlapped with each other is stably attached to the side plate 54. Since the first and second connectors 61 and 62 can be brought into contact with each other, the temporarily fixed state of the first and second connectors 61 and 62 is further stabilized. As a result, the accuracy when the first and second connectors 61 and 62 are permanently fixed by brazing It can be improved.

更に、脚部６７と第１の接続口６３および第２の接続口６４との間に間隔Ｓを設けたので、第１・第２の接続口６３，６４の溶融したロー材が脚部６７に接触するのを防止できる。つまり、溶融したロー材が脚部６７に接触した場合にはそのロー材が毛細管現象で他の部位に漏出してしまうことになるが、本実施形態では、間隔Ｓを設けてロー材の漏出を防止できることにより、第１・第２のコネクタ６１，６２と第１・第２の接続口６３，６４とのロー付けによる接合性を良好な状態に維持できる。   Further, since the space S is provided between the leg portion 67 and the first connection port 63 and the second connection port 64, the molten brazing material of the first and second connection ports 63 and 64 is added to the leg portion 67. Can be prevented from touching. That is, when the melted brazing material comes into contact with the leg portion 67, the brazing material leaks to other parts due to capillary action, but in this embodiment, the spacing material S is provided to leak the brazing material. Can prevent the first and second connectors 61 and 62 and the first and second connection ports 63 and 64 from joining together by brazing.

尚、本実施形態では第２のコネクタのフランジ部６６が第１のコネクタのフランジ部６５とサイドプレート５４との間に挟持される関係上、第１のコネクタ６１と第１の接続口６３との間を加締めてあり、また、第２のコネクタのフランジ部６６に脚部６７を設けた場合を開示したが、第１のコネクタのフランジ部６５が第２のコネクタのフランジ部６６とサイドプレート５４との間に挟持される場合は、第２のコネクタ６２と第２の接続口６４との間を加締めるとともに、第１のコネクタのフランジ部６５に脚部６７を設けることになる。   In the present embodiment, since the flange portion 66 of the second connector is sandwiched between the flange portion 65 of the first connector and the side plate 54, the first connector 61 and the first connection port 63 Is disclosed, and the flange portion 66 of the second connector is provided with the leg portion 67. However, the flange portion 65 of the first connector and the flange portion 66 of the second connector are side-mounted. When sandwiched between the plate 54 and the second connector 62 and the second connection port 64, the leg portion 67 is provided on the flange portion 65 of the first connector.

図１５〜１６は第３実施形態の変形例を示し、図１５は第２のコネクタの正面図、図１６は第２のコネクタの側面図である、上述の第３実施形態では位置決め部６６ａが第１実施形態と同様にＵ字状の切欠部として構成されているが、本変形例では位置決め部６６ｃが第２実施形態と同様に円形状の開口部として構成されたものである。   15 to 16 show a modification of the third embodiment, FIG. 15 is a front view of the second connector, and FIG. 16 is a side view of the second connector. In the third embodiment, the positioning portion 66a is Although it is configured as a U-shaped notch as in the first embodiment, in this modification, the positioning portion 66c is configured as a circular opening as in the second embodiment.

尚、本変形例では位置決め部６６ｃの周縁部に形成される段差部６６ｄは、第３実施形態と同様に第２のコネクタのフランジ部６６が第１のコネクタのフランジ部６５とサイドプレート５４との間に挟持される関係上、第２のコネクタのフランジ部６６のサイドプレート５４とは反対側の面に形成される。   In this modification, the step portion 66d formed on the peripheral portion of the positioning portion 66c is similar to the third embodiment in that the flange portion 66 of the second connector is replaced with the flange portion 65 of the first connector and the side plate 54. The flange portion 66 of the second connector is formed on the surface opposite to the side plate 54 in view of being sandwiched between the two.

また、本変形例にあっても第２のコネクタのフランジ部６６のサイドプレート５４に対向する面に脚部６７が設けられるが、この脚部６７は第２のコネクタ６２の接続固定部６２ａを中心として位置決め部６６ａとは反対側を略半円状に囲繞して設けられるとともに、位置決め部６６ｃを中心として第２のコネクタ６２とは反対側を略半円状に囲繞して設けられる。   Further, even in this modified example, the leg portion 67 is provided on the surface of the flange portion 66 of the second connector that faces the side plate 54. The leg portion 67 is provided with the connection fixing portion 62a of the second connector 62. The center is provided so as to surround the side opposite to the positioning portion 66a in a substantially semicircular shape, and the side opposite to the second connector 62 is provided in a substantially semicircular shape around the positioning portion 66c.

従って、本変形例にあっても第２のコネクタのフランジ部６６に脚部６７を設けたので、上述の第３実施形態と同様に第１・第２のコネクタ６１，６２の仮固定状態をより安定化させることができる。勿論、この場合にあっても脚部６７と第１・第２の接続口６３，６４との間に間隔Ｓを設けることが好ましい。   Therefore, since the leg portion 67 is provided on the flange portion 66 of the second connector even in this modification, the temporarily fixed state of the first and second connectors 61 and 62 is set in the same manner as in the third embodiment. It can be further stabilized. Of course, even in this case, it is preferable to provide an interval S between the leg portion 67 and the first and second connection ports 63 and 64.
