Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for fixing and positioning the housing of a cylindrical capacitor.

[0002]

[Prior art]

 As shown in FIG. 1, a conventional cylindrical housing 1 is provided with a cylindrical room 2 therein, and a cylindrical element 3 formed by surrounding a metallic plastic film is arranged in the room. Then, the above-mentioned members are all inserted into the cylindrical housing 1 and then further fixed by glue to complete the condenser. The cylindrical capacitor is clamped to it by a circular clamp 4 and then penetrated through both rectangular holes 43, 44 of the circular clamp 4 by a screw 41 and screwed by a nut 42 so that the cylindrical housing 1 is It is fixed to the attached object. As described above, conventionally, the housing of the cylindrical condenser is clamped by the circular clamp 4 in order to fix the housing of the cylindrical condenser to the object to be mounted, which is very complicated and uncertain. Further, as shown in FIG. 2, another conventional cylindrical condenser is provided with a round hole 2a1 at the top of a cylindrical room 2a in a housing 1a and is provided with a T-shaped screw rod 4a for insertion. The condenser is fixed in a good position only after inserting the Liu rod 4a into the center of the front, so when fixing by glue, push the screw rod 4a to the correct position or fix it. After that, in order to prevent the screw rod 4a from being bent obliquely, it takes a lot of man-hours and time for processing, and there is a drawback that the cost increases. In order to prevent the screw rod 4a and the cylindrical element 3a from coming into contact with each other, an insulating plate is provided below the round hole 2a1 at the top of the cylindrical room 2a before the cylindrical element 3a is placed in the cylindrical room 2a. Since it is necessary to insert 3b, this also causes an increase in cost.

[0003]

[Problems to be Solved by the Invention]

 An object of the present invention is to provide a cylindrical capacitor that overcomes the above drawbacks.

[0004]

[Means for Solving the Problems]

 The applicant has conducted extensive research and, after many trial manufactures, finally does not need to use a circular clamp, a screw and a nut, and places the screw rod on the outside of the housing, thereby using an insulating plate. It has become possible to provide a structure for fixing and orienting the housing of a cylindrical capacitor that fixes the cylindrical capacitor to the object to which it is attached, without the need for it. That is, the purpose is to provide an insertion groove at the upper end of the cylindrical housing, the insertion groove is U-shaped, and a U-shaped curved plate lower than the screw rod is provided for insertion into the insertion groove and the insertion groove is inserted. It is configured to form a close fit with the two stop plates in the groove, and is also configured to insulate the cylindrical element located in the cylindrical room, in which case the screw rod is It is perpendicular to the outer U-shaped notch and is located in the center of the front of the housing. The housing of the cylindrical capacitor is fixed and oriented by screwing and fixing it to the object to be mounted with a screw rod. Achieved by structure.

【Example】

 FIG. 4 shows an exploded view of the cylindrical capacitor of the present invention, which includes a housing 10, has a cylindrical room 11 in the housing 10, and has an insertion groove 12 at the upper end of the housing 10, and the insertion groove 12 is provided. Is U-shaped, the insertion groove 12 is provided with two blocking plates 121, and the outer shape of the two blocking plates 121 is a U-shaped notch 13.

An electric wire 201 is provided below the cylindrical element 20. The screw rod 30 has an inverted T shape, and the T shape includes a U-shaped curved plate 301, and the bottom surface of the screw rod 30 is a raised U-shaped plate 302. The U-shaped curved plate 301 is slightly lower, and is directly inserted into the insertion groove 12 at the upper end of the housing 10 as an insertion portion.

The manufacturing process of the cylindrical capacitor composed of the above members can be integrated by an automated production facility. A feature of the present invention is that the insertion groove 12 on the upper end of the housing 10 is formed as a flat surface without a circular hole, and the cylindrical element 20 and the screw rod 30 arranged in the cylindrical room 11 are U. By arranging the curved U-shaped plate 301 to have an insulating function, it is possible to omit laying an insulating plate in the cylindrical room 11, and to incline both sides of the U-shaped curved plate 301 to the insertion groove 12. In this case, the screw rod 30 and the U-shaped notch 13 on the outer side of the two blocking plates 121 are perpendicular to each other and the housing 10 is formed. Since it is located in the center of the front of the machine, the operator does not need to pay special attention to alignment, and the entire cylindrical condenser is By screwed and fixed directly to the object attaching the rod 30, it can be localized by fixing its entirety Shirindorika Le condenser.

[0008]

[Effect of device]

 In the present invention, the insertion groove 12 and the blocking plate 121 are provided at the upper end of the housing 10, and the insertion groove 12 and the cylindrical room 11 have an insulating function, so that there is no need for an insulating plate and the screw rod 30 can be localized. There is no need for the operator to take corrective action with special care, and there is no need to fix the housing with a circular clamp, which is highly economical in mass production during the manufacturing process, and it can be said from the standpoint of fixation and localization. If it is quick, it has the effect of saving man-hours and assembly time.
