Description

[Detailed Description of the Invention] The present invention relates to a capacitor enclosed in a prismatic resin case.

As shown in FIG. 1, a conventional capacitor encased in a square resin case has, for example, a metallicon electrode 2 formed on both end faces of a metallized plastic film capacitor element 1, a lead wire 3 attached to the metallicon electrode 2, and then a square resin case. Store it in case 4 and store it in case 4.
The gap is filled with sealing resin 5, and then ratings and other necessary information are stamped on the surface of the square resin case 4 using stamp ink such as heat curing ink or ultraviolet curing ink.
It is formed by forming. However, the prismatic resin cased capacitors constructed in this way are assembled and used in various devices by users, but in recent years, the automation of the assembly process at users has progressed, and automatic supply systems using parts feeders have been adopted. There is. This is due to the vibration feeding by the feeder's diaphragm, and in some cases the feed is not delivered smoothly and the flow stagnates, and in some cases it may take up to 10 minutes for some items to flow.
Since the device vibrates on the diaphragm for a long time and rubs against the diaphragm, if the surface that rubs against the diaphragm is the surface on which the display section 6 is formed, the display section 6 may be supplied while being turned off. It had

The present invention was developed in view of the above points, and by forming a protrusion on the display forming surface of the prismatic resin case, the risk of the display disappearing due to friction with the diaphragm is eliminated. The purpose of this invention is to provide a capacitor housed in a square resin case.

An embodiment of the present invention will be described below with reference to the drawings. That is, as shown in FIG. 2, metallicon electrodes 12 are formed on both end faces of a capacitor element 11 formed by laminating and winding a pair of metalized plastic films or metalized paper, and lead terminals 13 are attached to the metallicon electrodes 12. do. Next, as shown in FIG. 3, the capacitor element 11 is housed in a rectangular resin case 15 in which a protrusion 14 is formed at an arbitrary location on one side at the same time as the molding process, and a sealing resin 16 is filled into the cavity of the case 15. After that, the rating and other necessary information are stamped on the surface of the square resin case 15 on which the protrusion 14 is formed, other than the protrusion 14, using stamp ink such as heat curing ink or ultraviolet curing ink. This is to form a stamp display section 17.

Since the capacitor configured as described above has the protrusion 14 formed on the surface of the stamp display section 17, even if the surface that rubs against the diaphragm during automatic feeding by the parts feeder is the surface of the stamp display section 17, the stamp display will still be displayed. The part 17 no longer comes into direct contact with the diaphragm,
Therefore, even if the flow does not flow smoothly due to stagnation and is left in one place for a long time in a state where it rubs against the diaphragm, it will never be supplied with the stamp display section 17 turned off. In the above embodiments, the protrusions are formed by molding simultaneously with the molding of the rectangular resin case. However, the present invention is not limited to this. For example, the protrusions may be formed by pinching and curing the resin. But it has the same effect.

As described above, according to the present invention, by forming protrusions at arbitrary locations on the stamp display forming surface of the prismatic resin case, the stamp can be displayed even if the case is left in contact with the diaphragm for a long time. It is possible to obtain a rectangular resin-cased capacitor with high practical value, which is particularly suitable for automatic supply by a parts feeder and whose parts do not disappear.
