Abstract

(57) [Abstract] [Purpose] Leads 6, 6 protruding outward from the case 1
In order to prevent the deformation of the leads 6 and 6 during transportation, the electrical parts provided with are required to have a specially shaped positioning member, and to prevent the leads 6 and 6 from contacting with other parts, they are packed. This is prevented because the density cannot be increased and the transportation cost increases. [Structure] On the side surface 8 of the case 1, lead fitting grooves 9, 9 into which the respective leads 6, 6 can be fitted are formed. The leads 6, 6 of one part A are connected to the lead fitting grooves 9, 9 of the adjacent part A.
By being fitted inside, deformation of the leads 6 and 6 is prevented, and the cases 1 and 1 can be arranged in a close contact state.

[Problems to be solved by the device]

  By the way, when transporting by the above method, there are positioning plates and partition plates. It requires a special member and has a lot of dead space to increase the packing density of electrical parts. There is a drawback that it requires a considerable transportation cost because it cannot be expensive.

[0004]   This invention was made to solve the above-mentioned conventional drawbacks, and its purpose is Is to provide an exterior structure for electrical parts that can reduce transportation costs more than ever before. It

[0005]

[Means for Solving the Problems]   Therefore, in the exterior structure of the electric component according to claim 1, the electric element 2 is housed in the element housing portion 7. , Of the electric component formed by leading out a plurality of leads 6, 6 from the element housing portion 7 to the outside. In the exterior structure, the side surface 8 of the element housing portion 7 is substantially the same as the leads 6, 6. Lead fitting grooves 9 that extend in substantially the same direction at intervals and into which the leads 6, 6 can be fitted. , 9 are provided.

[0006]   In the exterior structure of the electrical component according to claim 2, the depth of the lead fitting groove 9 is a lead wire diameter. Alternatively, it is characterized in that it is 10% or more, preferably 50% or more of the lead thickness. It

[0007]   The exterior structure of an electric component according to claim 3, wherein the electric element 2 is a bottomed box-shaped resin case. The lead fitting grooves 9 and 9 are housed in the same and molded with a resin 3. Is formed on the side surface 8 of the resin case 1.

[0008]   The outer structure of the electrical component according to claim 4 is such that the lead is inserted through the bottom surface 4 of the resin case 1. Through-holes 5 and 5 are provided, and the leads 6 and 6 are outwardly extended through the through-holes 5 and 5. It is characterized by being derived.

[0009]

[Action]

  FIG. 3 shows an embodiment of the present invention in the exterior structure of an electric component according to claim 1. Like in the lead fitting grooves 9, 9 of one electric component A, the other Since the leads 6, 6 of the electric component A of FIG. As shown in FIG. 4, the element accommodating portions 7, 7 are brought into close contact with each other in the lateral direction, and each lead 6 , 6 are fitted in the lead fitting grooves 9, 9 at a position between the element housing portions 7, 7. It is possible to dispose the leads 6 while preventing the leads 6 from being deformed.

[0010]   The depth of the lead fitting groove 9 is not particularly limited, but it is preferable to set it as in claim 2. Good

[0011]   Further, the lead fitting groove 9 is formed in the resin case 1 as in the exterior structure of an electric component according to claim 3. If the groove is formed, the groove can be formed easily and accurately.

[0012]   Further, as in the exterior structure of the electric component according to claim 4, the bottom surface 4 of the resin case 1 is releasable. If the through holes 5 and 5 for inserting the through holes are formed, the arrangement pitch of the leads 6 and 6 can be further reduced. It is convenient to implement because it can be set accurately.

[0013]

【Example】

  First, the schematic structure of the electric component A will be described with reference to FIG. In the figure, 1 is a resin case having a box shape with a bottom and a rectangular cross section. The capacitor element 2 is housed and a resin mold 3 is applied. Resin case The bottom surface 4 of the capacitor 1 has a pair of through holes 5 and 5 formed therein. The lead wires 6 and 6 are led out to the outside through the through holes 5 and 5. The above The resin case 1 and the resin mold 3 constitute an element housing portion 7.

[0014]   Then, as shown in FIG. 1, on both side surfaces 8 in the thickness direction of the resin case 1, the above-mentioned A pair of lead fitting grooves 9, 9 extending in the same direction as the lead wires 6, 6 at substantially the same intervals are provided. Each is formed. The lead fitting grooves 9, 9 are about half of the lead wires 6, 6. Or, it is preferable to make it possible to insert a little more than that. However, it is not particularly limited to this.

[0015]   According to the electric component A having the above structure, as shown in FIG. The lead wire of the other electric component A arranged in the insertion groove 9 and adjacent to the insertion groove 9. It is possible to insert 6, 6. Therefore, as shown in FIG. Another row Y adjacent between the resin cases 1 and 1 of the electric components A of the specified row X In a state where the lead wires 6 of the electric component A are fitted in the lead fitting grooves 9, 9. While arranging, the lead wires 6, 6 of the electric component A of the specific row X are connected to the adjacent next row Z. It becomes possible to arrange between the resin cases 1 and 1. In this case, each lead wire 6, 6 Of the lead fitting groove 9 is restricted.

[0016]   Since the arrangement in this manner is possible, the arrangement in the packaging box 10 Increases density and eliminates the need for special parts, which reduces the cost of transportation. It becomes possible to reduce. A space O formed at the bottom of the packaging box 10, In P, a spacer having a shape matching this may be arranged.

[0017]   In addition, before the resin mold 3 is applied, that is, when the resin case 1 is a single product. If the lead insertion grooves 9, 9 are formed, the machining becomes easy and the lead insertion groove 9 is accurately performed. It will also be obtained.

[0018]   Further, if through holes 5 and 5 for inserting leads are formed in the bottom surface 4 of the resin case 1, The lead wires 6 and 6 can be arranged at a precise pitch, which facilitates the stacking work during packaging. You can do it.

[0019]   The embodiment of the exterior structure of the electric component of the present invention has been described above. The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above, the lead fitting grooves 9, 9 are formed on both side surfaces 8, 8 of the resin case 1. However, this may be formed only on one side surface 8, or each lead fitting groove 9, 9 The resin case 1 may be formed not in the entire length but in a part thereof. Again Although the example in which the resin mold 3 is applied is shown in the above description, May be. Further, in the illustrated example, the lead wire 6 having a circular cross section is used. The leads referred to in (1) include flat terminals and the like. Furthermore, in the above, the electric element Although the capacitor element is shown as an example, it is suitable for elements other than those used for electronic applications. However, the same application is possible.

[0020]

[Effect of device]

  In the exterior structure of an electric component according to claim 1, the arrangement of the electric component is denser than in the conventional case. It is possible to improve transportation cost and transport cost because no special member is required. Can be reduced.

[0021]   Further, as in the exterior structure of an electric component according to claim 3, a lead fitting groove is formed in the resin case. If it is formed, there is an advantage that the groove can be formed easily and accurately.

[0022]   Further, as in the outer structure for electric parts according to claim 4, the lead is inserted on the bottom surface of the resin case. By forming common through holes, it is possible to more accurately determine the arrangement pitch of each lead. Since it is possible, it is easy to insert each lead into the lead insertion groove. Occurs.
