Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is an insulation for an electric junction box having a laminated structure of bus bar wiring such as a junction block and an insulating plate used for centralized connection of circuits for electric parts of automobiles. Regarding the combination of plates and magazines.

[Conventional technology]

Conventionally, in assembling this kind of electrical junction box, the outer shapes of a plurality of insulating plates used in the same assembly line are usually formed to be completely the same.

Therefore, the electric junction box generally has a structure as illustrated in the exploded perspective view of FIG.

That is, in the figure, 1 is a main cover, 2, 2 ', 2 "
Is the bus bar wiring formed in the predetermined wiring path, 3,
Reference numeral 3'denotes an insulating plate in which the bus bars to be stacked are respectively interposed between the wirings 2, 2 ', 2 ", and the tab terminals 2a, 2'a provided on the bus bar wiring are provided on the respective insulating plates 3, 3'. , 2 ″ a insertion hole 3a,
3'a is provided. 4 is the back copper.

In order to assemble the electric junction box having such a structure, first, the bus bar 2 ″ is assembled to the back cover 4 in the first step. Next, the insulating plate 3 ′ is shown in FIG. 5 (b) in the second step. As shown in FIG. 5, the insulating plate 3'is taken out from the magazine 5'which is exclusively stored, and the bus bar 2'is attached to the magazine 5 '. Next, in the third step, the assembly of the insulating plate 3'and the bus bar 2'is assembled. Assemble on the bus bar 2 ″ assembled in the first step.
Next, in the fourth step, as shown in FIG. 5A, the insulating plate 3 is taken out from the magazine 5 in which only the insulating plate 3 is stored, and the bus bar 2 is attached thereto. Then, in a fifth step, the assembly of the insulating plate 3 and the bus bar 2 is assembled on the bus bar 2'assembled in the third step. Next, in the sixth step, the female-female terminal 6 is inserted into the tab terminals 2a, 2'a, 2 "a protruding from the upper surface of the final laminate, and the main cover 1 is assembled in the final step to complete the assembly. The assembly is automatically performed by a robot or the like when each part reaches a predetermined position on a continuous assembly line.

[Problems to be solved by the invention]

However, the conventional insulating plates 3 and 3'used for assembling such an electric connection box are specific ones in which the positions of the insertion holes 3a and 3'a of the bus bar tab terminals respectively provided are different. , It is difficult to distinguish at first glance because their outer shapes are exactly the same, and when the respective insulating plates 3 and 3'are stored in the predetermined magazines 5 and 5 ', they may be mistakenly stored in a magazine other than the predetermined one. , Insulation plate 3, 3'even in the prescribed magazine
There is a problem in that the above-mentioned assembly becomes impossible by mistakenly storing the front and back sides, and the operation of the assembly line is often interrupted.

The present invention has been made focusing on such a problem.
A combination structure of an insulating plate and a magazine for an electrical junction box that can store the specified insulating plates in the specified magazines without any mistakes, and does not cause incorrect storage in the specified magazines or reverse storage in the specified magazines. The purpose is to provide.

[Means for solving problems]

That is, the combination of the insulating plate for an electric junction box and the magazine of the present invention is used in an electric junction box having a laminated structure of a plurality of bus bar wirings and a plurality of insulating plates. A plurality of magazines corresponding to, and forming a notch or a protrusion having a different position and / or shape for each insulating plate at one position deviated from the center of the corner or side of each insulating plate, Each of the insulating plates is characterized in that the front and back sides are specified and stored in respective dedicated magazines having guides corresponding to the respective cutouts or protrusions.

〔Example〕

In the insulating plates A ₁ and A ₂ shown in FIG. ₁ , a rectangular cutout 7a is provided at one corner of the insulating plate A ₁ , and one side of the side 8 of the insulating plate A ₂ is provided. A rectangular notch 7b is formed at a position deviated from the center of the portion 8 to the right.

In the insulating plates A ₃ and A ₄ shown in FIG. 2, a triangular notch 7c is provided at one corner of the insulating plate A _{3 and} the insulating plate A ₄
A square cutout 7d is formed at one corner of the square.

Therefore, the magazines in which these insulating plates A _{1 to} A ₄ are individually stored are stored in a magazine corresponding to different outer shape of each insulating plate in order to prevent erroneous storage of each insulating plate in a magazine other than the specified one. Configured to have a section. That is,
For example, a magazine 9 for storing the insulating plate A ₁ shown in FIG.
As shown in FIG. 3, the inner wall corner portion (two-sided joint portion) corresponding to the cutout portion 7a provided in the insulating plate A ₁ is formed inward in the storage space into a planar shape corresponding to the shape of the cutout portion 7a. Notch
It is manufactured in a structure in which a guide 10 for 7a is formed.

Further, the notches or protrusions formed on the insulating plate of the present invention may have different shapes, or may have the same shape but different shape positions.

[Action]

The cutouts 7a, 7b or 7c, 7d provided in the insulating plates A ₁ , A ₂ or A ₃ , A _{4 of the present invention} are located at the positions deviated from the centers of the corners or sides of each insulating plate. Each insulating plate is formed in a different position and / or shape, and the insulating plate storage portion of the magazine is provided with the guide 10 for the notch so that each insulating plate is erroneously stored in a magazine other than its own. It also has the function of completely preventing even a dedicated magazine from being stored upside down.

[Effect of device]

As described above, the present invention comprises a plurality of insulating plates used in an electric junction box having a laminated structure of a plurality of bus bar wirings and a plurality of insulating plates, and a plurality of magazines corresponding to the plurality of insulating plates. A notch or protrusion having a different position and / or shape for each insulating plate is formed at one position deviated from the center of the corner or side of each insulating plate, and each insulating plate is provided with each notch or Since the front and back sides are specified and stored in dedicated magazines that have guides corresponding to the protrusions, a plurality of insulating plates used in the process of assembling the electrical junction box can be used for each predetermined magazine. It is not stored in anything other than
Reverse storage of the specified front and back sides in a given magazine is also completely prevented. Therefore, a plurality of insulating plates are surely supplied to the assembly line in a fixed order based on a simple work of simply ordering the magazines for storing the magazines. Insulation failure and even if the insulation plate is a predetermined insulating plate, the assembly failure due to the reverse stacking on the front and back can be resolved, the operation of the assembly line can be prevented from being interrupted, and the cost loss due to the assembly failure can be reduced. It is possible to improve the work efficiency of assembling the electric junction box.

Further, since the cutout portion or the protruding portion is formed only at one place of the insulating plate, there is an advantage that the dead space in the insulating plate is reduced and the circuit design becomes easy.
