Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting device for fixing a cylindrical chemical capacitor (electrolytic capacitor) used in weak light electrical equipment such as audio equipment to a fixed portion such as a chassis.

[0002]

[Prior art]

 Conventionally, in this type of cylindrical condenser, two condensers are assembled in parallel in an upright posture, the body of the condenser is wound with a band-shaped binding band, and the ends of the band are fastened with screws.

[0003]

[Problems to be solved by the device]

 However, in this conventional means, since the fastening screw is oriented in the lateral direction, the screwdriver must be laid sideways and turned to tighten the screw. In many cases, electrical equipment such as audio equipment has many parts and equipment built into a compact frame, and there is little space to lie the driver sideways to work, so it is very difficult to tighten the above-mentioned capacitor binding band. It was

Therefore, the present invention aims at facilitating the mounting operation by enabling the screw to be rotated from above when fixing the capacitor, and at the same time, it is possible to fix the capacitor stably and surely. Its main purpose is to provide a mounting device.

It is configured so that it can be fitted into the member (4) from above, and the portion of the insertion hole (2) ... facing the center member (4) is open and inserted into the insertion hole (2). The condenser (A) is formed so as to be adjacent to the outer peripheral surface of the fixture (4). A screw hole (5) extending vertically is formed at the center of the material (4), and the upper plate (6b) of the fixture (6) is concentric with the screw hole (5) of the center member (4). The tightening screw insertion hole (8) is formed, and the center member (4) is provided with an enlarged part (4a) whose diameter is smaller at the lower part than at the upper part by taper or protruding ribs. The structure is the same as the standard structure.

[0006]

[Action]

 In the condenser mounting device constructed as described above, after inserting the cylindrical condenser (A) into the insertion hole (2) of the condenser holder (1), the fixture (6) is attached to the center member (4). When fitted and tightened with the tightening screw (7), the fixture (6) is pushed down in sequence, and the body part of this is expanded part (4a) formed on the outer peripheral surface of the shaft part of the center member (4). ), It spreads out in the radial direction, and by doing so, the peripheral surface of the capacitor (A) inserted in the insertion hole (2) is strongly pressed outwards, and the capacitor can be stably fixed and held. Also, since the tightening screw (9) can be tightened from above, workability is good.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, reference numeral (1) is a capacitor holder integrally formed of a synthetic resin material, which penetrates vertically from a shaft-shaped center member (4) divided by thin partition walls (3). It has four condenser insertion holes (2). The material for forming the capacitor holder (4) is preferably a flexible synthetic resin such as ABS, polyethylene or nylon.

Reference numeral (6) is a fixing tool for fixing the condenser inserted in the insertion hole (2), which is formed of a cylindrical body having an open lower surface, and whose peripheral wall is formed of the above-mentioned material. A slit (6a) into which the partition wall (3) fits is formed so that it can be fitted into the center member (4) from above. Furthermore, the portion of the insertion hole (2) facing the center member (4) is open, and the condenser (A) inserted in the insertion hole (2) is adjacent to the outer peripheral surface of the fixture (4). Is formed. A screw hole (5) extending vertically is formed in the center of the center member (4), and the upper plate (6b) of the fixture (6) also has a screw hole (5) of the center member (4). There is a tightening screw insertion hole (8) that is concentric with the screw hole (5), and the long screw tightening screw (7) is inserted from this screw insertion hole (8) and screwed into the screw hole (5). It is formed so that it can fit together. Further, the center member (4) is provided with an enlarged portion (4a) ... whose lower part has a larger diameter than its upper part. In the figure, (9) ... shows screw holes for attaching the capacitor holder (1) to the chassis of electric equipment, and (10) ... shows the peripheral wall part of the capacitor insertion hole (2). It shows the slit holes for promoting the deformation of the.

In use, first, after inserting the condenser (A) into the insertion hole (2) of the condenser holding body (1), the fixing member (6) is fitted on the center member (4) and the tightening screw ( When tightened with (7), the fixture (6) is pushed down sequentially, and the body of the fixture (6) is radially spread by the rib (4a) formed on the outer peripheral surface of the shaft of the center member (4). As a result, the peripheral surface of the capacitor (A) inserted in the insertion hole (2) is strongly pressed outward, and the capacitor can be stably fixed and held.

In the above-mentioned embodiment, the expanding portion (4a) is provided by the protruding rib on the lower peripheral surface of the center member (4) as a means for expanding the body portion of the fixture (6). Instead of this, the shaft portion of the center member may be formed in a tapered shape such that the diameter becomes larger toward the lower side.

Although a typical embodiment of the present invention has been described above, the present invention is not necessarily limited to only the above-described embodiment structure. For example, the number of the capacitor insertion holes (2) may be changed to four or more in the above-mentioned embodiment and may be changed to two or more, and the other constituent features of the present invention and within an effective range. Needless to say, it can be implemented with appropriate changes.

[Effect of device]

 Since the present invention is configured as described above, by fitting the fixture to the center member and tightening it with the tightening screw, the body of the fixture is pressed against the outer peripheral surface of the condenser and the opposite capacitor insertion hole is formed. The condenser can be firmly clamped and fixed to the inner peripheral surface, and especially when the condenser is attached, the tightening screw can be rotated from above, so that it is not disturbed by surrounding installation parts. It has an excellent effect that it can be easily performed and the workability of assembling can be improved.
