In such a basic configuration, the vehicle multiple fuse device 30 is located on the circuit board 10 at a position different from the fusing part 6 for protecting the charging current and is not covered with the insulator housing 20. After connecting with the alternator side bus bar part 5 and being covered with the insulator housing 20, a temporary joint part 7b (7) is provided which is removed over a predetermined section.
In FIG. 1, the provisional joint portion 7 (see FIG. 2A) has already been removed over a predetermined section, and the remaining portion 7b remaining as a result is visible. The provisional joint portion 7 will be described in detail with reference to FIG.
In addition to the above-described multiple fuse device 30 for a vehicle, the battery-side bus bar portion 4 and the alternator-side bus bar portion 5 are respectively connected to the battery-side bus bar portion 4 and the alternator-side bus bar portion 5 as constituent elements of the circuit board 10. A connecting portion 3 for connecting the plurality of input / output terminals 2 and the battery connection terminal 4a or the alternator connection terminal 5a is provided.
Further, the temporary joint portion 7 is provided in a temporary joint portion recess 12 that is recessed from the outer edge of the insulator housing 20, and as shown in FIG. 1B, the remaining portion 7b is a temporary joint portion recess. It doesn't jump out of 12.
The insulator housing 20 is provided with an accommodating portion 13 that accommodates the plurality of individual fusing portions 1 and one charging current protecting fusing portion 6. In the accommodating portion 13, a partition wall 14 is provided between adjacent individual fusing portions 1 and the like.
At this time, the charging current protection fusing part 6 is arranged between the individual fusing part 1 of the battery-side bus bar part 4 and the individual fusing part 1 of the alternator-side bus bar part 5, so that the accommodating part 13 is arranged. Can also be formed as a rectangular space as shown, and the structure can be simplified.
Further, it is possible to determine whether the individual fusing parts 1 are blown on both sides (upper and lower sides of the paper surface in FIG. 1B) of the opening of the housing part 13 and safety at the time of fusing. A transparent cover 15 is provided to enhance the above. The cover 15 can also be configured as a simple rectangular plate in accordance with the simple rectangular shape of the accommodating portion 13.
The material of the circuit board 10 is a copper alloy plate as described above. The material of the insulator housing 20 is not limited as long as it is an insulator, but a synthetic resin, in particular, a polyamide-based resin is preferable from the viewpoints of moldability and cost.
The operational effects of the vehicle multiple fuse device 30 having such a configuration will be described below with reference to FIG.
2A and 2B show an assembly procedure of the multiple fuse device for a vehicle shown in FIG. 1, wherein FIG. 2A is a front view showing a prepared circuit board, and FIG. 2B is a front view showing the circuit board of FIG. (C) is AA sectional drawing of (b), (d) is the elements on larger scale which show the state which removed the temporary connection part from the state of (b) by the predetermined section.
When assembling the vehicle multiple fuse device 30 of FIG. 1, first, a circuit board 10 as shown in FIG. 2A is prepared.
This circuit board 10 is made of a copper alloy plate material, a battery-side bus bar part 4, an alternator-side bus bar part 5, a charging current protection fusing part 6 and a temporary connecting part 7 for connecting the two, a battery connection terminal 4a, After the alternator connection terminal 5a is punched and formed, the battery connection terminal 4a and the alternator connection terminal 5a are bent as shown in FIG.
Therefore, parts other than the bent battery connection terminal 4a and alternator connection terminal 5a, that is, the individual fusing part 1, the input / output terminal 2, the connection part 3, the battery side bus bar part 4, the alternator side bus bar part 5 charging current. The fusing part 6 for protection and the temporary joint part 7 are on one plane and are plate-shaped.
Moreover, the battery side bus bar part 4 and the alternator side bus bar part 5 have the same thickness and width, and are in a straight line in the respective longitudinal directions, have a simple configuration, are easy to form, and are easy to handle. The shape is easy to do.
Here, as can be seen from FIG. 2A, the battery-side bus bar portion 4 and the alternator-side bus bar portion 5 are connected not only by the charging current protection fusing portion 6 but also by the temporary connecting portion 7. Since the result is connected at two places, the circuit board 10 maintains a firm strength as a whole and suppresses the charging current protection fusing part 6 from being deformed or broken in the assembly process.
Further, since the temporary joint portion 7 is a portion to be removed later, it is possible to increase the thickness according to the request without the need for narrowing from the request for the fuse function as in the charging current protection fusing portion 6. In that case, the strength of the circuit board 10 can be further improved and the charging current protection fusing part 6 can be more fully prevented from being deformed or broken.
Next, as shown in FIG. 2 (b), the planar portion of the circuit board 10 is insulatively covered with the insulator housing 20, leaving only the portion used for connecting the input / output terminals 2 and the temporary joint portion 7. At this time, in this example, the circuit board 10 is sandwiched between the flat insulator housings 20 and is fastened at necessary points with screw means, and the two are integrated to firmly maintain the planar state. It becomes.
In this state, the battery-side bus bar portion 4 and the alternator-side bus bar portion 5 are fixed to each other, and the charging current protection fusing portion 6 is not subjected to a load. The role of the provisional joint portion 7 as a means is finished.
Therefore, as shown in FIG. 2D, the temporary joint portion 7 is removed over a predetermined section (this removed portion is indicated by a two-dot chain line in the drawing and is referred to as “removal portion 7a”). ) And the battery-side bus bar part 4 and the alternator-side bus bar part 5 are not connected, and both the bus bar parts 4 and 5 are connected only by the charging current protection fusing part 6, and the original charging current protection fusing part. Function 6 will be exhibited.
Here, the temporary joint portion 7 is not covered with the insulator housing 20, and the pair of remaining portions 7 b remaining after the removal portion 7 a is removed is configured to protrude from the insulator housing 20. ing.
In this way, if the remaining portion 7b protrudes somewhat from the insulator housing 20, the removal can be performed without touching the insulator housing 20 when the removal portion 7a is removed. can do.
Further, since the remaining portion 7a is cut and removed so as not to jump out from the recess 12 for the temporary joint portion, the remaining portion does not become a catching element to the outside, and there is a possibility of contact by an external conductor. Can be reduced.
Thus, the vehicle multiple fuse device 30 shown in FIG. 1 is obtained. And as above-mentioned, this multiple fuse device 30 for vehicles is provided with the temporary joint part 7, and it becomes less likely that the fusing part 6 for a charging current protection deform | transforms or fractures | ruptures in an assembly process. The effect is demonstrated.
FIG. 3A is a plan view showing another example of the vehicle multiple fuse device of the present invention, FIG. 3B is an enlarged front view of the main part thereof, and FIG. 3C is a front view thereof. From here on, the same parts as those already described are given the same reference numerals, and redundant description is omitted.
The vehicle multiple fuse device 30A is located in the middle of the pair of remaining portions 7a in the insulator housing 20A as compared with the vehicle multiple fuse device 30 described in FIGS. The difference is that a short-circuit prevention unit 11 that prevents a short circuit between the remaining portions 7a is provided.
In this example, since the temporary joint portion 7 is provided in the temporary joint portion recess 12 as in the multiple fuse device 30 for a vehicle, the short-circuit prevention portion 11 is also provided in the temporary joint portion recess 12. Although it is provided, as will be described later, the position of the short-circuit prevention portion 11 may be between the pair of remaining portions 7a, and is not necessarily provided in the recess of the insulator housing.
FIG. 4A is an external perspective view showing a usage state of the vehicle multiple fuse device of FIG. 3, and FIG. 4B is a partially enlarged explanatory view of FIG.
In addition to the operational effects of the above-described vehicle multiple fuse device 30, the vehicle multiple fuse device 30A has a remaining portion that remains after the cut portion 7a is removed from the temporary joint portion 7 as shown in FIG. Even if the insulator housing 20 protrudes 7b (which is a conductor), the effect due to the presence of the short-circuit prevention portion 11 protruding in the intermediate portion is exhibited.
That is, as illustrated in FIG. 3B, even if the tip portion of the tool T such as a screwdriver may be brought into contact with either one of the remaining portions 7b, It is impossible to make contact that crosses simultaneously, and it is possible to avoid a short circuit between the remaining portions 7b.
Furthermore, since the pair of remaining portions 7b and the short-circuit preventing portion 11 are provided in the temporary connecting portion recess 12 that penetrates from the outer edge portion of the insulator housing 20, the short-circuit preventing function is better. Demonstrated.
5 (a) and 5 (b) are front views showing other examples of the circuit board which is a component of the vehicle multiple fuse device of the present invention.
The circuit board 10A of FIG. 5A is a position different from the individual fusing part 1 on the circuit board 10A as compared with the circuit board 10 shown in FIG. A difference is that individual temporary connecting portions 8 that are removed after the plurality of adjacent input / output terminals 2 are connected and covered with the insulator housing 20 are provided. The individual connecting portion 8 is configured to connect the sides of the input / output terminal 2 to each other.
In this way, each of the input / output terminals 2 extending through the individual fusing part 1 that is narrow and weak like the charging current protection fusing part 6 is displaced or missing during the assembly process. Can be reduced.
Therefore, you may make it provide these separate temporary connection parts 8 as needed.
In the figure, the individual temporary connecting portions 8 are provided only between the input terminals 2 of the battery-side bus bar portion 4 and only between the input terminals 2 of the alternator-side bus bar portion 5. As described above, an individual temporary connecting portion 8A that connects the battery side and the alternator side may be provided.
When such an individual temporary joint portion 8A is provided, the deformation suppressing function is more effectively exhibited.
Further, even when this circuit board 10A is used, the insulator housing 20 may be the same, and the vehicle multiple fuse device 30B constituted by these exhibits the effect of the circuit board 10A as a fuse device.
The circuit board 10B in FIG. 5B is different from the circuit board 10A in FIG. 5A only in that the individual temporary connecting portions 9 are connected to the ends of the input / output terminals 2. .
Therefore, this circuit board 10B basically exhibits the same effect as the circuit board 10A, and in this case, the individual temporary joint portion 9A indicated by the two-dot chain line also exhibits the same effect.
In addition, since the circuit board 10B and the temporary connecting portion 9A are to be cut at only one place on the input / output terminal 2 on the end side, the number of cutting steps can be reduced. In addition, even if a cutting residue occurs, the cutting accuracy can be made rougher because it does not obstruct the insertion / removal direction of the mating concave terminal with respect to the input / output terminal 2.
Further, even when the circuit board 10B is used, the insulator housing 20 may be the same, and the vehicle multiple fuse device 30C constituted by these exhibits the effect of the circuit board 10B as a fuse device.
FIGS. 6 (a1) to (a3) are front views of essential parts showing the assembly procedure of another example of the vehicle multiple fuse device of the present invention, and (b1) to (b3) are vehicle multiple trains of the present invention. It is a principal part front view which shows the assembly procedure of the other example of a type | mold fuse apparatus.
6 (a1) to (a3) and (b1) to (b3) are respectively in the same order as FIGS. 2 (b), 2 (c), and 1 (b) regarding the first embodiment. The assembling procedure and completed state of the embodiment are shown in enlarged views of the fusing part for protecting the charging current and the temporary joint part.
The multiple fuse device 30C for a vehicle shown in FIGS. 6 (a1) to 6 (a3) has a pair of remaining portions 7b and a short-circuit prevention portion as compared with the multiple fuse devices 30 and 30A for a vehicle shown in FIGS. 11A is different in that it is provided on the outer edge portion (flat portion) of the insulator housing 20B.
Thus, even when the pair of remaining portions 7b and the short-circuit prevention portion 11A are not provided in the temporary connecting portion recess 12, the short-circuit prevention portion 11A is interposed between the pair of remaining portions 7b, The short circuit prevention function is fully demonstrated.
The vehicle multiple fuse device 30D shown in FIGS. 6 (b1) to 6 (b3) is compared with the vehicle multiple fuse device 30 shown in FIGS. 1 and 2 at the outer edge portion of the insulator housing 20C. There is no place 12, and when the temporary joint portion 7 is removed, it enters the outer edge portion of the insulator housing 20C, and the removal portion 7c is removed together with the insulator housing 20C.
If it does in this way, the remaining part 7d will be in the state which is pinched | interposed into the insulator housing 20C in the part dented from the outer edge part of the flat insulator housing 20C, and does not protrude. As a result, the insulator housing 20C sandwiched between the remaining portions 7d functions as a short-circuit prevention portion 11B that protrudes as a result and prevents a short circuit between the remaining portions 7d.
Therefore, even with such a method, the short-circuit prevention part 11B can be formed, and the same effect as the short-circuit prevention part 11 of FIGS.
The present invention has been described above based on the embodiments. However, the above-described embodiments can be variously improved and modified without departing from the gist of the present invention. included.
