特許文献１のソレノイドには、ケース部材が圧縮機ハウジングから突出して外部環境に露出しているので、ケース部材に高度の耐食表面処理を施す必要があり、製造コストの上昇を招くという問題がある。
本発明は上記問題に鑑みてなされたものであり、従来に比べて耐食性に優れ、製造コストが低減したソレノイドを提供することを目的とする。 In the solenoid of Patent Document 1, since the case member protrudes from the compressor housing and is exposed to the external environment, it is necessary to subject the case member to a highly corrosion-resistant surface treatment, which causes an increase in manufacturing cost. .

樹脂部材が筒状部材に密着して筒状部材のケース部材から離隔する側の端部を閉じると共にスリーブの一端を覆うので、ソレノイド内部への水の侵入が阻止され、コイル部材の防水性が確保される。 In order to solve the above-described problems, in the present invention, a case member made of a magnetic material that houses a coil member therein, a sleeve disposed inside the coil member, and a fixed iron core disposed in the sleeve, A movable iron core, a cylindrical member made of a magnetic material disposed radially outward near one end of the sleeve and joined to one end of the case member and facing the fixed iron core or the movable iron core, and an outer periphery of the cylindrical member And a resin member that closes the end of the tubular member that is in close contact with the tubular member and is spaced apart from the case member, and that covers one end of the sleeve. To do.
The cylindrical member is directed rearward in the traveling direction, the solenoid according to the present invention is inserted into the accommodation hole formed in the compressor housing, and the sealing member disposed on the outer periphery of the cylindrical member is connected to the peripheral wall of the accommodation hole opening. To seal the gap between the tubular member and the peripheral wall of the opening of the accommodation hole. The case member is shielded from the external environment, and the corrosion resistance of the solenoid is improved as compared with the conventional case. Since the grade of the corrosion-resistant surface treatment of the case member can be lowered as compared with the conventional case, the manufacturing cost of the solenoid is reduced as compared with the conventional case.
Since the resin member is in close contact with the cylindrical member and closes the end of the cylindrical member that is separated from the case member and covers one end of the sleeve, water penetration into the solenoid is prevented and the coil member is waterproof. Secured.

本発明の好ましい態様においては、 筒状部材とコイル部材とは、インサート成形により、樹脂部材と合体しており、筒状部材の外周面は樹脂から露出しており、当該外周面に形成された周溝にシール部材が収容されている。
筒状部材とコイル部材とを、インサート成形により、樹脂部材と合体させることにより、部品構成が簡素化され、ソレノイドの組立性が向上する。樹脂から露出した筒状部材の外周面の周溝にシール部材を収容して、筒状部材と収容孔開口部周壁との間の隙間を確実に封止することができる。 In a preferred aspect of the present invention, the cylindrical member and the coil member are combined with the resin member by insert molding, and the outer peripheral surface of the cylindrical member is exposed from the resin, and is formed on the outer peripheral surface. A seal member is accommodated in the circumferential groove.
By combining the cylindrical member and the coil member with the resin member by insert molding, the component configuration is simplified and the assembly of the solenoid is improved. The sealing member can be accommodated in the circumferential groove on the outer peripheral surface of the cylindrical member exposed from the resin, and the gap between the cylindrical member and the peripheral wall of the accommodation hole opening can be reliably sealed.

本発明の好ましい態様においては、筒状部材とケース部材とは鉄系材料から成り、それぞれ耐食表面処理され、ケース部材の耐食表面処理は筒状部材の耐食表面処理よりも低グレードである。
筒状部材は外部環境に曝露されるので、従来と同等の耐食表面処理をする必要がある。ケース部材は外部環境に曝露されないので、耐食表面処理のグレードを筒状部材に比べて、ひいては従来に比べて落とすことができる。ケース部材の耐食表面処理のグレードを従来に比べて落とすことにより、ソレノイドの製造コストが従来に比べて低減する。 In a preferred embodiment of the present invention, the cylindrical member and the case member are made of an iron-based material, and each is subjected to a corrosion-resistant surface treatment. The corrosion-resistant surface treatment of the case member is lower grade than the corrosion-resistant surface treatment of the cylindrical member.
Since the cylindrical member is exposed to the external environment, it is necessary to perform a corrosion-resistant surface treatment equivalent to the conventional one. Since the case member is not exposed to the external environment, the grade of the corrosion-resistant surface treatment can be lowered as compared with the cylindrical member, and thus compared with the conventional case. By reducing the grade of the corrosion-resistant surface treatment of the case member as compared with the conventional case, the manufacturing cost of the solenoid is reduced as compared with the conventional case.

本発明の好ましい態様においては、筒状部材は電磁ステンレス材料から成る。
筒状部材を電磁ステンレス材料で形成することにより、筒状部材の耐食表面処理の省略が可能になり、ソレノイドの製造コストが更に低減する。 In a preferred embodiment of the present invention, the cylindrical member is made of an electromagnetic stainless material.
By forming the cylindrical member from an electromagnetic stainless steel material, the corrosion-resistant surface treatment of the cylindrical member can be omitted, and the manufacturing cost of the solenoid is further reduced.

筒状部材を進行方向後方へ差し向けて、本発明に係るソレノイドを、圧縮機ハウジングに形成した収容孔に挿入し、筒状部材の外周に配設したシール部材を、収容孔開口部の周壁に押し当てて、筒状部材と収容孔開口部周壁との間の隙間を封止する。ケース部材が外部環境から遮断され、ソレノイドの耐食性が従来に比べて向上する。ケース部材の耐食表面処理のグレードを従来に比べて落とせるので、ソレノイドの製造コストが従来に比べて低減する。 The cylindrical member is directed rearward in the traveling direction, the solenoid according to the present invention is inserted into the accommodation hole formed in the compressor housing, and the sealing member disposed on the outer periphery of the cylindrical member is connected to the peripheral wall of the accommodation hole opening. To seal the gap between the tubular member and the peripheral wall of the opening of the accommodation hole. The case member is shielded from the external environment, and the corrosion resistance of the solenoid is improved as compared with the conventional case. Since the grade of the corrosion-resistant surface treatment of the case member can be lowered as compared with the conventional case, the manufacturing cost of the solenoid is reduced as compared with the conventional case.

筒状部材１０８の外周面と周溝１０８ａとは樹脂から露出している。
筒状部材１０８とケース部材１０１とは、それぞれ耐食表面処理されている。ケース部材１０１の耐食表面処理は筒状部材１０８の耐食表面処理よりも低グレードである。
可動鉄心１０５は、図示しない弁機構と連結している。 Examples of the present invention will be described.
As shown in FIG. 1, a solenoid 100 of a capacity control valve includes a case member 101 made of an iron-based magnetic material having a cylindrical portion 101a and a bottom portion 101b, a coil member 102 accommodated in the case member 101, and a coil member. A cylindrical sleeve 103 made of a non-magnetic material, which is disposed on the inner side of 102 and closed on the open end 101c side of the case member 101, a fixed iron core 104 disposed in the sleeve 103, and a sleeve 103, a movable iron core 105 facing the fixed iron core 104 with a predetermined gap therebetween, a solenoid rod 106 fixed to the movable iron core 105 and inserted into the fixed iron core 104, and engaged with the solenoid rod 106. A spring 107 that urges the movable core 105 away from the fixed core 104 and radially outward near the closed end of the sleeve 103. A cylindrical member 108 made of an iron-based magnetic material facing the end of the fixed iron core 104 that is spaced from the movable iron core 105 and is crimped to the open end 101c of the case member 101; The O-ring 109 accommodated in the circumferential groove 108a is combined with the cylindrical member 108 and the coil member 102 by insert molding, and is in close contact with the inner peripheral surface of the cylindrical member 108 to be separated from the case member 101 of the cylindrical member 108. The connector 110 is made of a resin material that closes the end of the side and covers the closed end of the sleeve 103, and an electrical connection terminal 111 disposed in the connector 110.
The outer peripheral surface of the cylindrical member 108 and the circumferential groove 108a are exposed from the resin.
The cylindrical member 108 and the case member 101 are each subjected to a corrosion-resistant surface treatment. The corrosion resistant surface treatment of the case member 101 is of a lower grade than the corrosion resistant surface treatment of the tubular member 108.
The movable iron core 105 is connected to a valve mechanism (not shown).

ソレノイド１００においては、コイル部材１０２に通電すると、ケース部材１０１、筒状部材１０８、固定鉄心１０４、可動鉄心１０５により磁気回路が形成され、バネ１０７の付勢力に抗して、可動鉄心１０５が固定鉄心１０４へ吸引される。コイル部材１０２への通電を停止すると、磁気回路が消滅し、バネ１０７の付勢力を受けて、可動鉄心１０５が固定鉄心１０４から離隔する。ソレノイドの作動により、可動鉄心１０５が連結する弁機構の作動が制御される。 In the solenoid 100, when the coil member 102 is energized, a magnetic circuit is formed by the case member 101, the cylindrical member 108, the fixed iron core 104, and the movable iron core 105, and the movable iron core 105 is fixed against the urging force of the spring 107. It is sucked into the iron core 104. When the energization to the coil member 102 is stopped, the magnetic circuit disappears and the movable core 105 is separated from the fixed core 104 by receiving the biasing force of the spring 107. The operation of the valve mechanism connected to the movable iron core 105 is controlled by the operation of the solenoid.

ソレノイド１００を備える容量制御弁を圧縮機に取り付ける際には、筒状部材１０８を進行方向後方へ差し向けて、圧縮機ハウジング２００に形成した収容孔２０１に弁機構とソレノイド１００とを挿入し、筒状部材１０８外周の周溝１０８ａに収容したＯリング１０９を、収容孔２０１開口部の周壁に押し当てて、筒状部材１０８と収容孔２０１開口部周壁との間の隙間を封止する。止め輪２０２を用いて、弁機構とソレノイド１００とを圧縮機のハウジング２００に固定する。 When the capacity control valve having the solenoid 100 is attached to the compressor, the valve member and the solenoid 100 are inserted into the accommodation hole 201 formed in the compressor housing 200 with the tubular member 108 directed rearward in the traveling direction. The O-ring 109 accommodated in the circumferential groove 108a on the outer periphery of the cylindrical member 108 is pressed against the peripheral wall of the opening of the receiving hole 201 to seal the gap between the cylindrical member 108 and the peripheral wall of the opening of the receiving hole 201. A retaining ring 202 is used to fix the valve mechanism and the solenoid 100 to the compressor housing 200.

ソレノイド１００は、コネクタ１１０を除いて収容孔２０１内に挿入され、Ｏリング１０９が筒状部材１０８と収容孔２０１開口部周壁との間の隙間を封止するので、ケース部材１０１は外部環境から遮断される。この結果、ソレノイド１００の耐食性は、従来に比べて向上する。
外部環境から遮断されたケース部材１０１の耐食表面処理のグレードは、従来に比べて落とせるので、ソレノイド１００の製造コストは、従来に比べて低減する。
コネクタ１１０が筒状部材１０８の内周面に密着して筒状部材１０８のケース部材から離隔する側の端部を閉じると共に、スリーブ１０３の閉鎖端を覆うので、ソレノイド内部への水の侵入が阻止され、コイル部材１０２の防水性が確保される。
筒状部材１０８とコイル部材１０２とをインサート成形してコネクタ１１０と合体させることにより、部品構成が簡素化され、ソレノイド１００の組立性が向上する。筒状部材１０８の外周面の樹脂から露出し耐食表面処理された周溝１０８ａにＯリング１０９を収容することにより、筒状部材１０８と収容孔２０１の開口部周壁との間の隙間を確実に封止することができる。
筒状部材１０８は外部環境に曝露されるので、従来と同等の耐食表面処理をする必要がある。ケース部材１０１は外部環境に曝露されないので、耐食表面処理のグレードを筒状部材１０８に比べて、ひいては従来に比べて落とすことができる。ケース部材１０１の耐食表面処理のグレードを従来に比べて落とすことにより、ソレノイド１００の製造コストが従来に比べて低減する。 The solenoid 100 is inserted into the accommodation hole 201 except for the connector 110, and the O-ring 109 seals the gap between the tubular member 108 and the peripheral wall of the opening of the accommodation hole 201. Blocked. As a result, the corrosion resistance of the solenoid 100 is improved as compared with the conventional case.
Since the grade of the corrosion-resistant surface treatment of the case member 101 cut off from the external environment can be reduced as compared with the conventional case, the manufacturing cost of the solenoid 100 is reduced as compared with the conventional case.
The connector 110 is in close contact with the inner peripheral surface of the cylindrical member 108 and closes the end of the cylindrical member 108 on the side away from the case member, and covers the closed end of the sleeve 103, so that water can enter the solenoid. This prevents the coil member 102 from being waterproof.
The cylindrical member 108 and the coil member 102 are insert-molded and combined with the connector 110, thereby simplifying the component configuration and improving the assembly of the solenoid 100. By accommodating the O-ring 109 in the circumferential groove 108a exposed from the resin on the outer peripheral surface of the cylindrical member 108 and subjected to the corrosion-resistant surface treatment, a gap between the cylindrical member 108 and the peripheral wall of the opening of the receiving hole 201 is ensured. It can be sealed.
Since the cylindrical member 108 is exposed to the external environment, it is necessary to perform a corrosion-resistant surface treatment equivalent to the conventional one. Since the case member 101 is not exposed to the external environment, the grade of the corrosion-resistant surface treatment can be lowered as compared with the tubular member 108 and thus compared to the conventional case. By reducing the grade of the corrosion-resistant surface treatment of the case member 101 as compared with the conventional case, the manufacturing cost of the solenoid 100 is reduced as compared with the conventional case.
