The junction box is a device that distributes power to various electrical devices installed in a car interior, which is an engine room of a car and a boarding space. Although there are some differences depending on the type of vehicle and the options to be selected in the automobile, approximately dozens of relays and a dozen fuses are provided. If such relays and fuses are disposed in a dispersed manner, the structure becomes complicated and control becomes difficult. The junction box thus has the form of being housed in a single case using a printed circuit board to integrate them in one place.

At this time, the printed circuit board used in the junction box is arranged in the vertical direction due to space constraints and the like. An input / output terminal for connecting a power source supplied from a battery of the vehicle and a distribution terminal for transmitting power distributed through the printed circuit board to each electric device of the vehicle are also arranged in the vertical direction.

As a result, the distribution terminal has to be bent at one end so as to be electrically connected to the printed circuit board. Further, a support housing is further used to support a distribution terminal to be joined in a bent shape.

However, in this conventional method, the bending type of the distribution terminal must be different according to the type of the vehicle, so that a new mold is required to be produced in accordance with the development of a new vehicle type and the like.

Further, the use of the support housing causes the weight of the junction box to increase, which is contrary to the lightweight trend, and causes the additional cost increase. In addition, although the printed circuit boards are arranged in pairs, the blocks that correspond to the basic specifications are assembled together on each printed circuit board, which causes cost increase.

[First Embodiment]

FIG. 1 is an exploded perspective view of the junction box according to the first embodiment of the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is an enlarged perspective view of part A of FIG. FIG. 5 is a plan view of the upper sub-PCB of FIG. 4, and FIG. 6 is a plan view of the lower sub-PCB of FIG.

1 to 6, a junction box to which the banding type PCB A according to the first embodiment is applied includes a main PCB 10, an upper sub PCB 20, a lower sub PCB 30, a banding PCB 40 ), A lower case 50 and an upper case 60. [

The main PCB 10 is a printed circuit board on which a block 95 including electric elements such as relays, chips, etc. is assembled. These main PCBs 10 are arranged to face each other in the vertical direction. That is, the main PCB 10 is arranged such that the two main PCBs 10 are symmetrically opposed to each other. At this time, spacers 92 may be interposed between the main PCBs 10 at predetermined intervals.

As described above, when the main PCBs 10 are arranged in pairs, the number of blocks 95 can be assembled in each main PCB 10, so that the function of the junction box can be greatly expanded. In the main PCB 10 according to the first embodiment, a first block 95a having a basic specification is assembled into one and a second block 95b having an optional specification is assembled with the other.

For example, at least one block assembled to the left main PCB 10, that is, the first block 95a, is composed of blocks that are essentially required for operation of various electrical devices provided in the vehicle. On the other hand, at least one or more blades 95b assembled to the right main PCB 10 may be installed in blocks 95, which are essentially required for the operation of a more extended electrical device due to the addition of optional features in the vehicle .

Recently, automobiles have been increasing in options due to continuous investment in the field of electric vehicles. However, for the higher priced cars, the majority of options are adopted and used as basic specifications.

Therefore, the blocks 95 assembled in the main PCB 10 are classified so that the first block 95a is used for the basic specification and the second block 95b is used for the option specification. That is, each of the blocks 95 thus distinguished is assembled at a preset position among the pair of main PCBs 10. As a result, it is possible to efficiently arrange the block 95 and to obtain the effect of cost reduction.

The upper substrate 20 is horizontally opposed to the upper end of the main PCB 10. The main PCB 10 is formed as a pair in which the main PCBs 10 are disposed opposite to each other as described above. The upper sub PCB 20 is also formed as a pair, one for each main PCB 10.

The lower sub-picture 30 is horizontally opposed to the lower end of the main PCB 10. That is, the lower sub-pixel 30 is formed in the same manner as the upper sub-panel 20. As a result, the upper sub-panel 20 and the lower sub-panel 30 are also opposed to each other.

The banding PCB 40 electrically connects the main PCB 10 and the upper sub PCB 20 and between the main PCB 10 and the lower sub PCB 30 respectively. At this time, the banding PCB 40 is formed of the copper foil layer 42 on which the circuit pattern is formed. As a result, the banding PCB 40 is excellent in deformation due to electrical conductivity and bending.

The fork type flat terminal 93 is vertically coupled to the upper sub PCB 20 and the input and output terminal 94 is vertically coupled to the lower sub PCB 30. The fork type flat terminal 93 is formed as a straight type universal terminal and can be commonly used regardless of the difference of the junction box according to the type of the vehicle. That is, the fork-type tail terminal 93 does not require a design change according to the difference of the junction box, and thus can reduce the investment of a new mold for manufacturing the same.

In addition, conventionally, the use of an injection molding such as a supporting housing due to the use of a distribution terminal having one end folded is no longer necessary, the weight of the junction box is reduced, the number of production processes is reduced, the defective rate is lowered, .

The input / output terminal 94 is a terminal electrically connected to a power source side connector 96 formed at an end of a cable connected to an automobile battery, and is inserted into the lower sub PCB 30.

However, when the banding PCB 40 formed of the copper foil layer 42 according to the first embodiment is used, the banding PCB 40 is bent in the vertical direction during the assembly process of the junction box and the downward deflection of the upper sub- Can occur.

In order to prevent this, a protruding protrusion 22 for preventing downward deflection of the upper sub PCB 20 connected to the banding PCB 40 is formed at the edge of the upper sub PCB 20, The fixing groove 32 is formed.

In the lower case 50, a lower side PCB 30 A vertical support plate 52 is formed which is fitted to the fixing groove 32 in a direction perpendicular to the vertical direction. Further, a connector groove is formed on the lower surface of the lower case 50, to which the power source side connector 96 is fitted.

At this time, the upper end of the vertical support plate (52) supports the lower surface of the protruding jaw (22). That is, the vertical support plate 52 contacts the lower surface of the protrusion 22 to support the upper sub PCB 20. At least one or more protrusions and corresponding vertical support plates 52 may be formed to stably support the upper substrate 20.

A seating groove is formed on the upper surface of the upper case 60 so that a plurality of fuses 97 can be disposed. That is, the case of the junction box is composed of the lower case 50 and the upper case 60. The upper case 60 is formed with a fixed cover piece 62 for pressing the upper surface of the protrusion to cover the upper surface of the side surface of the vertical support plate 52.

Specifically, the fixed lid piece 62 protrudes outward from the upper case 60 and has a size corresponding to the length of the protruded lid. When the protruded lid 22 is coupled by the fixed lid piece 62, It is possible to prevent the bending plate 40 from being twisted in the left and right directions due to the fixing of the PCB 20.

That is, the protruding jaw 22 is brought into contact with the lower surface of the vertical support plate 52, and the fixed lid piece 62 is brought into contact with the upper surface thereof. As a result, the banding cover 40 made of the copper foil layer 42 can be prevented from being bent upward, downward, and laterally.

Therefore, even if the banding PCB 40 is used, the upper sub PCB 20 is supported and the upper sub PCB 20 is prevented from being twisted in the horizontal direction due to the twist deformation of the banding PCB 40, It is unnecessary to use.

Hereinafter, a procedure of assembling the junction box to which the banding type PCB A according to the first embodiment of the present invention is applied will be described. Except for the copper foil layer 42 and the PSR layer 43 in which the circuit pattern is formed to form the banding facies 40 in the PCB.

Then, the forked terminal 93, the input / output terminal 94, and the block 95 are coupled to the PC. Then, the copper foil layer 42 is bent at 90 degrees to form a banding PCB 40.

A pair of banding-type PCBs (A) formed as described above are provided so as to have a bilaterally symmetrical structure, and are spaced apart from each other by spacers 92.

The copper foil layer 42 and the PSR layer 43 are sequentially formed on both sides of the insulating layer 41 in accordance with the specification as well as the PC having the copper foil layer 42 and the PSR layer 43 formed on one side of the insulating layer 41 Can also be used.

The copper foil layer 42 is laminated on the outer surface of the insulating layer 41 and is formed in a circuit pattern to electrically connect the PCB. The PSR layer 43 is laminated on the outermost side of the PCB with an ink layer, and is electrically insulated from the outside and protects the copper foil layer 42. Therefore, the band-shaped PCB A is electrically connected to the other structure only at the connected portion such as the forked terminal 93, the block 95, and the like.

In the second step, only the insulating layer 41 is cut to form a bending portion B. At this time, they are electrically connected by the copper foil layer 42 while forming steps of the PCB disposed on both sides.

22, in the case of using a plastic substrate in which the copper foil layer 42 and the PSR layer 43 are formed on both sides of the insulating layer 41, A part of the copper foil layer 42, the PSR layer 43 and the insulating layer 41 formed on the substrate 40 is cut to form a bending portion B. At this time, the copper foil layer 42 and the PSR layer 43 are directly formed on one side of the bending portion B and electrically connected to the PCB disposed on both sides through the same.

Therefore, as shown in FIG. 23, the cross section of the formed PCB is formed by recessing the bending portion B, having the same stepped portions on both sides, and having a shape in which the PCB is connected, And the thickness is made thin.

Step 3 is a step of positioning the PCB formed with the bending portion B on the lower plate 412 of the bending jig. It is preferable that the bending portion B is positioned between the lower plate 412 of the bending jig and the bending portion 413 of the bending jig to facilitate bending of the bending portion B. [

In the fourth step, the upper plate 411 of the bending jig is positioned to overlap the upper side of the lower plate 412, and the pressure is fixed by pressing. At this time, the upper plate 411 is connected to the lower plate 412 and rotates, and is moved to the upper side of the PCB.

It is preferable that the upper plate 411 has one end connected to the lower plate 412 and the other end rotated so as to be positioned at a portion where the bending portion B starts. Therefore, it is preferable that the bottom surface of the top plate 411, which is in contact with the PCB, is recessed by the step of the bending portion B at the distal end.

The fifth step is to bend the bending part B formed on the outer side of the lower plate to form the banding package A. At this time, the bending portion 413 connected to the lower plate 411 is rotated, and the bending portion 413 is bent in contact with the other end of the upper side to form the bending plate 40.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. .
