Summary of the Invention

Problem to be Solved by the Invention

[0005] In recent years, with the increasing number of devices to which power is supplied, the number of fuses, and therefore the number of connection terminals, has also been increasing. While an increase in the number of connection terminals expands the area on the circuit board occupied by these terminals, the installation space for electrical junction boxes is limited, often preventing an increase in the size of the electrical junction box, and thus the size of the circuit board. Therefore, even when attempting to increase the number of fuses, securing sufficient space for the connection terminals (electrical components) on the circuit board can be difficult.

[0006] To solve this problem, as shown in Figure 7, a technique can be conceived in which a metal plate is punched out in an L-shape to form a connection terminal 105, and the fuse is positioned so that both ends are parallel to the circuit board, and the front and back surfaces of the connection terminal 105 are perpendicular to the circuit board (vertically positioned) in order to secure space for placement. However, as shown in Figure 7, this sometimes resulted in a decrease in the yield rate of the connection terminal 105 and an increase in manufacturing costs.

[0007] The present invention aims to provide terminals, electrical component connection structures, and electrical connection boxes that can connect more electrical components without increasing the size of the circuit board, while reducing manufacturing costs. [Means for solving the problem]

[0008] To solve the aforementioned problems and achieve the objective, the terminal of the present invention as described in claim 1 is a terminal for connecting an electrical component and a substrate, comprising: a plate-shaped component connection portion connected to the electrical component; a plate-shaped substrate connection portion connected to the substrate; and a connecting portion connecting the component connection portion and the substrate connection portion, wherein a rectangular metal plate is bent to form an L-shape, and has a first notch formed by cutting out one edge in the width direction at the boundary position between the component connection portion and the connecting portion, and a second notch formed by cutting out the other edge in the width direction at the boundary position between the substrate connection portion and the connecting portion, and is configured to be bent with the longitudinal line of the metal plate connecting the first notch and the second notch as the first fold, and is configured such that the thickness direction of one of the component connection portion and the width direction of the other are in the same direction. The terminal is formed by folding along a line connecting the tip of the second notch and one edge in the width direction at the boundary between the substrate connection portion and the connecting portion, with this line forming the second fold. This terminal is characterized by the following features. Furthermore, the terminal of the present invention as described in claim 2 is a terminal for connecting an electrical component and a substrate, comprising: a plate-shaped component connection portion connected to the electrical component; a plate-shaped substrate connection portion connected to the substrate; and a connecting portion connecting the component connection portion and the substrate connection portion, wherein a rectangular metal plate is bent to form an L-shape, and has a first notch formed by cutting out one edge in the width direction at the boundary position between the component connection portion and the connecting portion, and a second notch formed by cutting out the other edge in the width direction at the boundary position between the substrate connection portion and the connecting portion, wherein the terminal is bent with a line in the longitudinal direction of the metal plate connecting the first notch and the second notch as the first fold, and the thickness direction of one of the component connection portion and the width direction of the other are in the same direction, and the terminal is characterized in that the terminal is bent with a line connecting the tip of the first notch and the other edge in the width direction at the boundary position between the component connection portion and the connecting portion as the third fold.

[0009] Furthermore, the electrical component connection structure of the present invention is an electrical component connection structure to which electrical components are connected, comprising a substrate connected to the electrical components, and a pair of terminals connecting the electrical components to the substrate, The terminal is a terminal for connecting the electrical component and the substrate, and comprises a plate-shaped component connection portion connected to the electrical component, a plate-shaped substrate connection portion connected to the substrate, and a connecting portion connecting the component connection portion and the substrate connection portion, and is formed by bending a rectangular metal plate into an L-shape, and has a first notch formed by cutting out one edge in the width direction at the boundary position between the component connection portion and the connecting portion, and a second notch formed by cutting out the other edge in the width direction at the boundary position between the substrate connection portion and the connecting portion, and is constructed by bending the metal plate along the longitudinal line connecting the first notch and the second notch as the first fold, and is configured such that the thickness direction of one of the component connection portion and the width direction of the other are in the same direction. This electrical component connection structure is characterized in that, with the pair of terminals connected to the substrate, the component connection portions of each of the pair of terminals are arranged to face each other and intersect with the plane direction of the substrate, and the substrate connection portions of each of the pair of terminals are provided side by side in the width direction of the substrate connection portion.

[0010] Furthermore, the electrical connection box of the present invention is characterized by comprising the electrical component connection structure and a housing that mounts the electrical components and houses the electrical component connection structure. [Effects of the Invention]

[Modes for carrying out the invention]

[0013] Hereinafter, an electrical junction box 10 according to one embodiment of the present invention will be described with reference to Figures 1 to 4. Figure 1 is a perspective view showing an electrical junction box according to one embodiment to which the terminals and electrical component connection structure of the present invention are applied. Figure 2 is a perspective view showing a state in which a fuse (electrical component) is connected to the terminals constituting the electrical junction box. Figure 3 is a diagram for explaining the manufacturing method of the terminals. Figure 4 is a diagram for explaining the operation and effects of this embodiment, where (A) is a perspective view showing a state in which a fuse (electrical component) is connected to the terminals of this embodiment, and (B) is a perspective view showing a state in which a fuse (electrical component) is connected to the terminals of a comparative example.

[0014] An electrical junction box 10 according to an embodiment of the present invention is mounted on an automobile and used for supplying electric power from a battery to a load side. In addition, a body ECU (Electronic Control Unit) 11 is provided on a surface of the electrical junction box 10 on one side in the Y direction, and is connector-connected to the electrical junction box 10.

[0015] As shown in FIGS. 1 and 4, the electrical junction box 10 includes a housing 2 (shown in FIG. 1), a substrate 3 supported by the housing 2 (shown in FIG. 4(A)), and each pair of connection terminals 5, 5 (a pair of terminals shown in FIG. 4) connected to both ends of each fuse 4 (electrical component). As shown in FIG. 4, the substrate 3 and the pair of connection terminals 5, 5 constitute an electrical component connection structure 1.

[0016] In the present embodiment, the X direction, the Y direction, and the Z direction are directions orthogonal to each other. As shown in FIG. 4, one direction among the planar directions of the substrate 3 is indicated by an arrow X, another direction is indicated by an arrow Z, and the direction orthogonal to the surface of the substrate 3 may be indicated by an arrow Y.

[0017] In addition, as shown in FIGS. 1 and 2, a plurality of fuses 4 are mounted in the electrical junction box 10 of the present embodiment.

[0018] As shown in FIG. 2, each fuse 4 includes a fuse body 41 having a fusible element enclosed therein, and a pair of terminal contact portions 42A, 42B which are located at both ends of the fusible element and connected to the pair of connection terminals 5, 5. Hereinafter, one of the pair of terminal contact portions 42A and 42B may be referred to as a "first terminal contact portion 42A", and the other may be referred to as a "second terminal contact portion 42B".

[0019] In addition, as shown in FIG. 4(A), the fuse 4 is disposed such that the first terminal contact portion 42A and the second terminal contact portion 42B face the substrate 3. That is, in the fuse 4 of the present embodiment, the first terminal contact portion 42A and the second terminal contact portion 42B are installed (arranged horizontally) so as to be parallel to the planar direction of the substrate 3.

[0020] As shown in Figure 1, the housing 2 comprises a flat rectangular box-shaped housing body 21 that supports the circuit board 3, and a fuse mounting section 22 provided on the lower (X-direction) surface of the housing body 21, on which a plurality of fuses 4 are mounted. The body ECU 11 is mounted on one side of the housing body 21 in the Y-direction. Furthermore, with the body ECU 11 installed on the housing body 21, the body ECU 11 is provided facing the circuit board 3 supported by the housing body 21.

[0021] The fuse mounting section 22 is provided on the lower (X-direction) side of the housing 2. The fuse mounting section 22 is provided with multiple insertion receiving sections (not shown) into which the fuse 4 is inserted. These insertion receiving sections are open in the X-direction and are arranged in a grid pattern in the Z-direction and Y-direction. In this embodiment, the multiple insertion receiving sections are arranged in rows in the Z-direction, with four (multiple) rows overlapping in the Y-direction.

[0022] In this embodiment, the first fuse 4 of the four fuses 4 may be referred to as "first fuse 4A," and the second fuse 4 as "second fuse 4B." In Figures 2 and 4, only the first fuse 4A and the second fuse 4B are shown, and the third and fourth fuses 4 are omitted.

[0023] The circuit board 3 is a rectangular printed circuit board on which circuit patterns are formed for power distribution circuits via fuses 4 and for connecting the body ECU 11 to external wire harnesses.

[0024] Furthermore, as shown in Figure 4(A), the substrate 3 has a pair of terminal holes 3A and 3B that are connected to each pair of connection terminals 5, 5. Each terminal hole 3A and 3B is made up of a through-hole with, for example, copper plating on its inner surface.

[0025] The pair of terminal holes 3A and 3B are arranged side by side in the Z direction, as shown in Figure 4(A). That is, the pair of terminal holes 3A and 3B connected to one fuse 4A via a pair of connection terminals 5, 5 are arranged side by side in the Z direction. Furthermore, the pair of terminal holes 3A and 3B connected to fuse 4A via a pair of connection terminals 5, 5 and the pair of terminal holes 3A and 3B connected to fuse 4B via a pair of connection terminals 5, 5 are spaced apart in the X direction.

[0026] Each connection terminal 5 is formed by punching and bending a rectangular metal plate 50 (shown in Figure 3), as shown in Figures 2 and 3. Each connection terminal 5 integrally comprises a plate-shaped component connection portion 51 that connects to the fuse 4, a plate-shaped substrate connection portion 52 that connects to the substrate 3, and a connecting portion 53 provided between the component connection portion 51 and the substrate connection portion 52 to connect them.

[0027] Furthermore, as shown in Figure 3, each connection terminal 5 has a first notch 54 formed by cutting out one edge 5A in the width direction at the boundary position 5a between the component connection portion 51 and the connecting portion 53, and a second notch 55 formed by cutting out the other edge 5B in the width direction at the boundary position 5b between the substrate connection portion 52 and the connecting portion 53.

[0028] In the component connection portion 51, the tip is formed in the shape of a bifurcated tuning fork, and is designed to grip the terminal contact portion 42 provided on the fuse 4.

[0029] As shown in Figures 2 and 3, the board connection portion 52 comprises a board connection portion body 520 and a connection end 521 provided at the end of the board connection portion body 520 away from the component connection portion 51, which can enter the respective terminal holes 3A and 3B of the board 3.

[0030] The first notch 54 is formed by cutting out one end edge 5A in the width direction at the boundary position 5a between the component connection portion 51 and the connecting portion 53, and extends to the center in the width direction of each connection terminal 5.

[0031] The second notch 55 is formed by cutting out the other edge 5B in the width direction at the boundary position 5b between the substrate connection portion 52 and the connecting portion 53, and extends to the center in the width direction of each connection terminal 5.

[0032] When manufacturing such a connector 5, as shown in Figure 3, a rectangular metal plate 50 is punched to form a punched body with a component connection portion 51, a substrate connection portion 52, a connecting portion 53, a first notch 54, and a second notch 55. In this punched body, a line L1 extending in the longitudinal direction of each connector 5 is bent as the first fold L1 (assigned the same reference numeral as line L1), and a line segment L2 connecting the tip 55S of the second notch 55 and the edge 5A on one side in the width direction at the boundary position 5b between the substrate connection portion 52 and the connecting portion 53 is bent as the second fold L2 (assigned the same reference numeral as line segment L2). In this way, the connector 5 is completed. As shown in Figure 2, the completed connector 5 is configured such that the thickness direction of the component connection portion 51 and the width direction of the substrate connection portion 52 are in the same direction.

[0033] Furthermore, in the assembled state, as shown in Figure 4(A), the component connection portions 51 of each of the pair of connection terminals 5, 5 are arranged facing each other and perpendicular (intersecting) to the plane direction of the circuit board 3 (hereinafter sometimes referred to as vertical arrangement), and the circuit board connection portions 52 of each of the pair of connection terminals 5, 5 are provided side by side in the width direction of the circuit board connection portion 52. In addition, one of the pair of connection terminals 5, 5 is connected to the first terminal contact portion 42A of the fuse 4 and inserted into the terminal hole 3A of the circuit board 3, and the other is connected to the second terminal contact portion 42B of the fuse 4 and inserted into the terminal hole 3B of the circuit board 3.

[0034] Furthermore, when electrically connecting each connection terminal 5 to the substrate 3, each connection terminal 5 is mounted to the substrate 3 by, for example, reflow heating with the substrate connection portions 52, 52 of each pair of connection terminals 5, 5 inserted into the respective terminal holes 3A, 3B of the substrate 3. That is, each connection terminal 5 is electrically connected to the circuit pattern formed on the substrate 3. In this embodiment, since the connection terminals 5 are arranged vertically relative to the substrate 3, heat from above can easily reach the substrate 3, allowing, for example, the solder to melt sufficiently.

[0035] Next, the effects of this embodiment will be explained with reference to Figures 4(A) and 4(B). Figure 4(A) is a perspective view showing the fuse 4 (electrical component) connected to the connection terminal 5 (terminal) of this embodiment, and (B) is a perspective view showing the fuse 4 (electrical component) connected to the connection terminal 105 of the comparative example.

[0036] In the electrical connection box 10 of this embodiment, the component connection portions 51 of each of the pair of connection terminals 5, 5 are arranged facing each other, as shown in Figure 4(A), and are also arranged vertically so as to be perpendicular (intersecting) to the plane direction of the substrate 3. Furthermore, the substrate connection portions 52 of each of the pair of connection terminals 5, 5 are provided side by side in the width direction of the substrate connection portion 52. Also, as shown in Figure 4(A), the pair of terminal holes 3A, 3B connected to the fuse 4A via the pair of connection terminals 5, 5 and the pair of terminal holes 3A, 3B connected to the fuse 4B via the pair of connection terminals 5, 5 are provided with a gap P1 in the X direction.

[0037] On the other hand, in the comparative example electrical junction box, the pair of connection terminals 105, 105 are arranged to face each other in their overall shape, as shown in Figure 4(B), and the connection terminal 105 connected to fuse 4A and the connection terminal 105 connected to fuse 4B are provided with a gap P100 in the X direction.

[0038] According to this, in this embodiment, since the connection terminal 5 connected to fuse 4A and the connection terminal 5 connected to fuse 4B are provided facing each other in the X direction, the spacing P1 in the X direction can be made smaller compared to the spacing P100 in the comparative example. That is, the spacing P1 between the terminal holes 3A and 3B on the substrate 3 can be made narrower. As a result, while saving space for arranging the pair of connection terminals 5, 5 on the substrate 3, more fuses 4 (electrical components) can be connected without increasing the size of the substrate 3.

[0039] According to the embodiment described above, each connection terminal 5 (terminal) comprises a plate-shaped component connection portion 51 connected to a fuse 4 (electrical component), a plate-shaped substrate connection portion 52 connected to a substrate 3, and a connecting portion 53 connecting the component connection portion 51 and the substrate connection portion 52. It is formed by bending a rectangular metal plate into an L-shape, and has a first notch 54 formed by cutting out one edge 5A in the width direction at the boundary position 5a between the component connection portion 51 and the connecting portion 53, and a second notch 55 formed by cutting out the other edge 5B in the width direction at the boundary position 5b between the substrate connection portion 52 and the connecting portion 53. It is constructed by bending the metal plate with a longitudinal line L1 connecting the first notch 54 and the second notch 55 as the first fold L1, and the thickness direction of the component connection portion 51 (one side) and the width direction of the substrate connection portion 52 (the other side) are in the same direction. According to this, compared to conventional technology, the material waste area is reduced and the yield of the connection terminal 5 (terminal) is improved, thereby reducing the manufacturing cost of the connection terminal 5.

[0040] Furthermore, the connection terminal 5 (terminal) is constructed by bending a line L2 that connects the tip 55S of the second notch 55 and one edge 5A in the width direction at the boundary position 5b between the board connection part 52 and the connecting part 53, with the line L2 forming the second fold L2. This makes it possible to reduce manufacturing costs and realize a configuration that allows more fuses 4 (electrical components) to be connected without increasing the size of the board 3.

[0041] Furthermore, the electrical component connection structure 1 to which the fuse 4 (electrical component) is connected comprises a circuit board 3 connected to the fuse 4, and a pair of connection terminals 5, 5 (terminals) that connect the fuse 4 to the circuit board 3. This allows for the connection of more fuses 4 without increasing the size of the circuit board 3, while reducing manufacturing costs.

[0042] Furthermore, with the pair of connection terminals 5, 5 (terminals) connected to the circuit board 3, the component connection portions 51 of each of the pair of connection terminals 5, 5 are arranged to face each other and to be perpendicular (intersecting) to the plane direction of the circuit board 3, and the circuit board connection portions 52 of each of the pair of connection terminals 5, 5 are provided side by side in the width direction of the circuit board connection portion 52. This makes it possible to reduce manufacturing costs and to connect more fuses 4 (electrical components) without increasing the size of the circuit board 3.

[0043] Furthermore, the device includes an electrical component connection structure 1 and a housing 2 that houses the electrical component connection structure 1 and also accommodates a fuse 4 (electrical component). This configuration allows for the connection of more fuses 4 (electrical components) without increasing the size of the circuit board 3, while reducing manufacturing costs.

[0044] Furthermore, as shown in Figure 3, the connection terminals 5 (terminals) are formed by punching and bending a rectangular metal plate 50, and in each connection terminal 5 (terminal), the width dimensions of the component connection portion 51, the board connection portion 52, and the connecting portion 53 are configured to be the same. In this way, each connection terminal 5 can connect from the fuse 4 to the board 3 without reducing the width dimension across the component connection portion 51, the connecting portion 53, and the board connection portion 52, thus ensuring the desired heat dissipation performance.

[0045] Furthermore, the present invention is not limited to the embodiments described above, and includes other configurations that can achieve the objectives of the present invention, as well as modifications such as those shown below.

[0046] In the above embodiment, each connection terminal 5 (terminal) is configured such that the thickness direction of the component connection portion 51 and the width direction of the substrate connection portion 52 are in the same direction, but the present invention is not limited thereto. As shown in Figures 5 and 6, the connection terminal 15 (terminal) may be configured such that the width direction of the component connection portion 51 and the thickness direction of the substrate connection portion 52 are in the same direction. That is, the connection terminal 15 may be configured such that the tip 54S of the first notch 54 and the tip 55S of the second notch 55 are connected, and a line L1 extending in the longitudinal direction of the connection terminal 15 is bent as the first fold L1, and a line segment L3 connecting the tip 54S of the first notch 54 and the edge 5B on one side in the width direction at the boundary position 5a between the component connection portion 51 and the connecting portion 53 is bent as the third fold L3 (assigned the same reference numeral as line segment L3), so that the width direction of the component connection portion 51 and the thickness direction of the substrate connection portion 52 are in the same direction. This provides the same effects as the above embodiment.

[0047] In this case, as shown in Figure 5, the component connection portions 51 of each pair of connection terminals 15, 15 may be arranged facing each other, and the board connection portions 52 of each pair of connection terminals 15, 15 may be arranged side by side in the width direction of the board connection portion 52.

[0048] Furthermore, although a fuse 4 is given as an example of an electrical component in the above embodiment, the present invention is not limited thereto. The electrical component may be a resistor, a capacitor, or any other electrical component that is connected to the circuit board 3.

[0049] Furthermore, while the best configurations and methods for carrying out the present invention are disclosed in the above description, the present invention is not limited thereto. That is, although the present invention is particularly illustrated and described with respect to specific embodiments, those skilled in the art can make various modifications to the embodiments described above in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and objectives of the present invention. Therefore, the limiting descriptions of shape, material, etc. disclosed above are provided as examples to facilitate understanding of the present invention and do not limit the present invention. Accordingly, descriptions of components with some or all of these limitations removed are included in the present invention. [Explanation of symbols]
