In the second embodiment, the same components and components having the same functions as those described in the first embodiment are denoted by the same reference numerals as those in the first embodiment, and description thereof is omitted.
[ first embodiment ]
As shown in fig. 1, an electrical connection box 1A of the present embodiment is a fuse box including a bus bar 2A and a junction box main body 3. The electrical connection box 1A has a substantially rectangular parallelepiped shape as a whole with the connection direction as the height direction, and in the present embodiment, the height direction is defined as the Z direction, and two directions orthogonal to each other in the horizontal plane are defined as the X direction and the Y direction.
The bus bar 2A is made of a plate material of a conductive metal such as copper or aluminum, and integrally includes a first plate portion 21, a second plate portion 22, a first connection plate 23, a second connection plate 24, and a connection portion 25, as shown in fig. 2.
The first plate portion 21 is formed in a flat plate shape along the ZX plane, and a plurality of terminal portions 211 protrude from one end edge in the Z direction. The second plate portion 22 is formed in a flat plate shape along the ZX plane, and a plurality of terminal portions 221 protrude from one end edge in the Z direction. The first plate portion 21 and the second plate portion 22 are arranged in parallel with each other with a space therebetween in the Y direction.
The first connecting plate 23 is formed in a flat plate shape along the ZX plane, and is connected to the first plate portion 21 via the third plate portion 26. The third plate portion 26 is formed in a plate shape along the YZ plane, is continuous with the X-direction one-side end edge of the first plate portion 21, and extends in a direction away from the second plate portion 22. That is, the first connecting plate 23 extends in parallel at a position distant from the second plate 22 with reference to the first plate 21.
The first plate portion 21, the third plate portion 26, and the first connection plate 23 constitute a first busbar portion 20A. The first busbar portion 20A extends along the ZX plane from the other side to the one side in the X direction (the first plate portion 21), extends along the YZ plane so as to be away from the second plate portion 22 (the third plate portion 26), and further extends along the ZX plane toward the one side in the X direction (the first connection plate 23).
A through hole 231 is formed in the first connection plate 23, and an external electric wire is connected to the first connection plate 23 by inserting a bolt through the through hole 231 and fastening the bolt to a nut. That is, the through hole 231 functions as a first connection portion.
The second connecting plate 24 is formed by extending the second plate portion 22 to one side in the X direction, and has a second connecting portion 241 protruding to the opposite side of the terminal portion 221. The second plate portion 22 and the second connecting plate 24 constitute a second busbar portion 20B.
The connecting portion 25 extends along the XY plane and connects the lower end edge of the first plate portion 21 and the lower end edge of the second plate portion 22. Thereby, the first plate portion 21 and the second plate portion 22 are formed integrally. That is, the first busbar portion 20A and the second busbar portion 20B are integrated, and the busbar 2A is formed of one member. The bus bar 2A has the connection portion 25, so that when the external electric wire is connected to the first connection plate 23, electric power is supplied to both the first plate portion 21 and the second plate portion 22. In the present embodiment, the connection portion 25 connects a part of the first plate portion 21 and a part of the second plate portion 22, but the entire first plate portion 21 may be connected to the entire second plate portion 22.
The junction box body 3 is formed of an insulating synthetic resin into a substantially rectangular parallelepiped, and has an upper surface in the Z direction serving as a mounting surface and a lower surface serving as a sealing surface. That is, the junction box main body 3 has a plurality of fuse mounting portions on an upper surface side, and a lower surface side is covered by a lower case or the like.
A first groove 31, a second groove 32, a third groove 33, a fourth groove 34, and a second electrical connection recess 36 are formed on the lower surface side of the junction box body 3. A first electrical connection recess 35 is formed on the upper surface side of the junction box main body 3.
The first groove portion 31 is a groove portion extending along the ZX plane, and accommodates the first plate portion 21 of the bus bar 2. The second groove portion 32 is a groove portion extending along the ZX plane, and accommodates the second plate portion 22 of the bus bar 2. The third groove portion 33 is a groove portion extending along the YZ plane, and accommodates the third plate portion 26 of the bus bar 2. The fourth groove portion 34 is a groove portion extending along the ZX plane, and accommodates a base end portion (a portion on the third plate portion 26 side) of the first connection plate 23.
The first electrical connection recess 35 is formed so as to be continuous with the tip of the fourth groove 34, and is continuous with the first groove 31 via the third groove 33 and the fourth groove 34. A portion of the first connection plate 23 where the through-hole 231 is formed is received in the first electrical connection recess 35. Thus, when the external electric wire is connected to the first connection plate 23, the terminal metal fitting, the fixing bolt, and the nut provided at the tip of the external electric wire are accommodated in the first electrical connection recess 35.
The second electrical connection recess 36 is continuous with one end side in the X direction of the second groove portion 32, and accommodates the second connection plate 24. The second electrical connection recess 36 functions as a female-type connector housing and can be fitted to a male-type connector housing constituting an external connector.
An upright wall 311 is formed on the first groove portion 31 on the side opposite to the second groove portion 32, and an upright wall 321 is formed on the second groove portion 32 on the side opposite to the first groove portion 31. The dividing portion 37 of the junction box main body 3 between the first groove portion 31 and the second groove portion 32 has a smaller projecting dimension than the projecting dimension of the standing walls 311, 321. Thus, the lower region in the Z direction of the dividing portion 37 functions as a communicating portion that communicates the lower ends of the first groove portion 31 and the second groove portion 32 with each other, and the connecting portion 25 is disposed.
When the bus bar 2A is accommodated in the junction box main body 3, the terminal portions 211 and 221 are disposed in the fuse mounting portions. Thereby, the fuse is mounted on the fuse mounting portion and electrically connected to the terminal portions 211 and 221.
According to the present embodiment, the following effects are obtained. That is, when the first plate portion 21 and the second plate portion 22 are separate bodies as in the second embodiment described later, the junction box body 3 can be made common.
[ second embodiment ]
As shown in fig. 3, the electrical connection box 1B of the present embodiment is a fuse box including bus bars 2B and a junction box main body 3. In the present embodiment, as in the first embodiment, the height direction of the electrical junction box 1B is defined as the Z direction, and 2 directions orthogonal to each other in a plane orthogonal to the height direction are defined as the X direction and the Y direction.
In the bus bar 2B, a first bus bar 20A including the first plate portion 21, the first connection plate 23, and the third plate portion 26 is formed separately from a second bus bar 20B including the second plate portion 22 and the second connection plate 24. Unlike the bus bar 2A of the first embodiment, the bus bar 2B does not have the connection portion 25.
The first plate portion 21 has a folded portion 212 in which a part of a lower end edge (an end edge on the opening side of the first groove portion 31, that is, an end edge on the communication portion side) is folded back toward the second plate portion 22. The second plate portion 22 has a folded portion 222 in which a part of a lower end edge (an end edge on the opening side of the second groove portion 32, that is, an end edge on the communication portion side) is folded back toward the first plate portion 21. The X-direction dimension and the Z-direction dimension of the folded portions 212 and 222 may be set as appropriate in accordance with the electrical characteristics and thermal characteristics required for the bus bar 2B in the electrical junction box 1B.
Note that the bus bar 2B in the present embodiment may be formed by appropriately processing the bus bar 2A in the first embodiment. That is, the bus bar 2A may be formed by cutting the connecting portion 25 and folding back a part of the connecting portion 25 that remains in the first plate portion 21 and the second plate portion 22 after the cutting, thereby forming the folded-back portions 212 and 222.
In the present embodiment, not only the external wire but also the terminal metal fitting of the external connector is connected to the first connection plate 23 and the second connection plate 24. That is, the connector housing of the external connector is fitted into the second electrical connection recess 36, and the terminal metal fitting of the external connector is in contact with the second connection plate 24. Thereby, electric power is supplied to the first busbar portion 20A through the external wires, and electric power is supplied to the second busbar portion 20B through the external connector.
According to the present embodiment, the following effects are obtained. That is, as in the first embodiment, when the first plate portion 21 and the second plate portion 22 are separate, the junction box body 3 can be made common.
Further, the first plate portion 21 and the second plate portion 22 are formed with the folded portions 212 and 222, so that the electrical characteristics and the thermal characteristics required for the bus bar 2B in the electrical junction box 1B can be easily satisfied. Even when the required electrical and thermal characteristics are different, the dimensions of the folded portions 212 and 222 can be adjusted to cope with the difference, and the components can be made common.
The present invention is not limited to the above-described embodiments, and includes other configurations and the like that can achieve the object of the present invention, and modifications and the like described below are also included in the present invention.
For example, in the second embodiment, the first plate portion 21 has the folded portion 211 and the second plate portion 22 has the folded portion 22, but only one plate portion may have the folded portion, and any plate portion may not have the folded portion, and the folded portion may be formed in accordance with the electrical and thermal characteristics required for the bus bar.
In the above embodiment, the electrical Junction boxes 1A and 1B are fuse boxes, but the electrical Junction boxes may be Junction boxes (Junction boxes) or the like as long as the electrical Junction boxes include conductive bus bars and insulating Junction box bodies.
The above description discloses the best configuration, method and the like for carrying out the present invention, but the present invention is not limited thereto. That is, although the present invention has been described mainly with reference to the specific embodiments shown in the drawings, those skilled in the art can modify the above-described embodiments in various ways with respect to the shape, material, quantity, and other detailed configurations without departing from the technical spirit and scope of the present invention. Therefore, the description of the shape, material, and the like disclosed above is an exemplary description for easy understanding of the present invention, and is not intended to limit the present invention, and therefore, the present invention also includes descriptions of names of members having a limitation that deviates from a part or all of the limitations of the shape, material, and the like.
