Technical problem to be solved by the invention
However, in the electrical connection box, the electrical connection member and the electronic component are accommodated in respective standard accommodation completion positions, so that a connection work for obtaining electrical connection between the electrical connection member and the electronic component can be performed. Therefore, in the electrical connection box, it is preferable to facilitate the work of accommodating the electrical connection member and the electronic component in order to improve the workability of assembling the electrical connection member and the electronic component.
Accordingly, an object of the present invention is to provide an electrical connection box having excellent workability in housing an electrical connection member and an electronic component.
Means for solving the problems
In order to achieve the above object, an electrical connection box according to the present invention includes: an electrical connection member having a1 st conductor and a 2 nd conductor orthogonally arranged in an L-shape; an electronic component having a1 st outer wall body and a 2 nd outer wall body, and an electrical connection portion electrically connected to the 1 st conductive body being provided on the 1 st outer wall body; a frame body having a1 st housing chamber for housing the electrical connection member at a1 st housing completion position, and having a 2 nd housing chamber for housing the electronic component at a 2 nd housing completion position, the 2 nd housing completion position being a position where the 1 st outer wall body is disposed to face the 1 st conductor of the electrical connection member at the 1 st housing completion position, and the 2 nd outer wall body is disposed to face the 2 nd conductor of the electrical connection member at the 1 st housing completion position; and a temporary holding mechanism capable of temporarily holding the electrical connection member in a temporary holding position in the housing, the temporary holding position being a position in which the electrical connection member is inclined with respect to the 1 st accommodation completion position and a free end side of the 2 nd conductor is lifted to a position higher than the 1 st conductor, the electrical connection member having a pushed body on the free end side of the 2 nd conductor, the pushed body being pushed from the temporary holding position to the 1 st accommodation completion position by the electronic component along an insertion trajectory of the electronic component into the 2 nd accommodation completion position.
Here, preferably, the temporary holding mechanism is provided at least one of the electrical connection member and the frame body.
Further, it is preferable that the temporary holding mechanism includes a temporary holding body as a protrusion protruding from a wall surface of the 1 st housing chamber and supporting a supported portion between the free end side and a fixed end side of the end portion of the 2 nd conductor viewed in an insertion direction of the electronic component into the 2 nd housing completion position at the temporary holding position.
Further, it is preferable that the temporary holding mechanism includes a temporary holding body as an elastic deformation body that protrudes from a wall surface of the 1 st housing chamber and that elastically deforms and supports a supported portion between the free end side and a fixed end side of the end portion of the 2 nd conductor viewed in an insertion direction in which the electronic component is inserted to the 2 nd housing completion position at the temporary holding position.
Further, it is preferable that the pushed body is disposed to face a 3 rd outer wall body disposed on an insertion direction side of the electronic component itself inserted to the 2 nd accommodation completion position, and is pushed by the 3 rd outer wall body.
Further, it is preferable that the 2 nd accommodation chamber has a placement surface on which the 3 rd outer wall body of the electronic component is placed in the 2 nd accommodation completion position, and the frame body has a recess that accommodates the pushed body when the electrical connection member is in the 1 st accommodation completion position.
Effects of the invention
In the electrical connection box according to the present invention, when the electrical connection member is held at the temporary holding position by the temporary holding mechanism in the housing, the 1 st conductor side of the insertion port for the electronic component formed by the electrical connection member is expanded as compared with the insertion port for the electronic component formed by the electrical connection member at the 1 st accommodation completion position. Thus, in the electrical connection box, the electronic component inserted from the insertion opening is not easily locked by the 1 st conductor, and the electronic component can be inserted to the 2 nd accommodation completion position. Further, in the electrical connection box, when insertion of the electronic component inserted from the insertion port is performed, the electronic component is caused to push the pushed body, and the electrical connection member is caused to shift from the temporary holding position to the 1 st accommodation completion position. In the electrical connection box according to the present invention, although the electrical connection member needs to be temporarily held at the temporary holding position, the electrical connection member can be moved from the temporary holding position to the 1 st accommodation completion position in conjunction with the operation of the electronic component accommodation operation. Therefore, compared to the configuration in which the electrical connection member is inserted into the 1 st housing completion position without being temporarily held at the temporary holding position, the electrical connection box can suppress a reduction in the workability of housing the electrical connection member into the housing. In addition, since the electronic component can be inserted into the 2 nd accommodation completion position without being stuck to the electrical connection member, the electrical connection box according to the present invention can suppress the occurrence of a situation in which the electrical connection member and the electronic component are accommodated again. Therefore, the electrical connection box according to the present invention can improve the workability of accommodating the electrical connection member and the electronic component.

Detailed Description
Hereinafter, an embodiment of an electrical junction box according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.
[ embodiment ]
One embodiment of an electrical junction box according to the present invention will be described with reference to fig. 1 to 9.
The electrical connection member 10 is formed of a conductive material such as metal. The electrical connection member 10 includes a1 st conductor 11 and a 2 nd conductor 12 (fig. 1 to 8) which are orthogonally arranged in an L-shape. Here, the 1 st conductor 11 and the 2 nd conductor 12 are each formed in a rectangular flat plate shape, and 1 side portion of each is formed as an intersection portion of each other. Thus, in the electrical connection member 10, the 1 st conductor 11 and the 2 nd conductor 12 are extended in the directions orthogonal to each other with the intersection as a starting point. In this example, a plate-shaped bus bar obtained by press-forming a metal plate such as a copper plate as a base material is used as the electrical connection member 10.
The electronic component 20 is, for example, a circuit protection component such as a relay or a fuse, a connector (for example, a connector attached to a terminal of an electric wire), a terminal fitting (for example, a terminal fitting attached to a terminal of an electric wire), or the like. Here, an electronic device such as a circuit board or an electronic control unit (so-called ECU) may be considered as one embodiment of the electronic component 20. The exemplary electronic component 20 includes: an electronic component main body (not shown); a frame 21 (fig. 1 to 7), the frame 21 accommodating the electronic component main body; at least 2 terminal fittings (described below), the 2 terminal fittings being electrically connected to the electronic component main body.
For example, when the electronic component 20 is a relay, the electronic component body refers to a circuit component such as a coil that constitutes a circuit of the relay. The frame 21 is formed of an insulating material such as synthetic resin. The housing 21 includes: a1 st outer wall body 21a, the 1 st outer wall body 21a being disposed facing the 1 st conductor 11 of the electrical connection member 10 with a gap therebetween; and a 2 nd outer wall body 21b, wherein the 2 nd outer wall body 21b is disposed to face the 2 nd conductor 12 of the electrical connection member 10 with a gap (fig. 1 to 6).
The illustrated housing 21 is a rectangular parallelepiped. Thus, in the illustrated housing 21, 2 outer walls orthogonally arranged out of 6 outer walls are used as the 1 st outer wall 21a and the 2 nd outer wall 21 b. The exemplary 1 st outer wall body 21a is disposed facing the plane of the 1 st conductor 11 with a gap in a state where its outer wall surface is parallel to the plane of the 1 st conductor 11. The 2 nd outer wall 21b illustrated in this example is disposed to face the plane of the 2 nd conductor 12 with a gap therebetween in a state where the outer wall surface thereof is parallel to the plane of the 2 nd conductor 12.
The exemplary electronic component 20 includes a1 st terminal fitting 22 and a 2 nd terminal fitting 23 (fig. 1, 2, 4, and 5). The 1 st terminal fitting 22 and the 2 nd terminal fitting 23 have electrical connection portions 22a and 23a, respectively, which are physically and electrically connected to the counterpart. In the electronic component 20, the electrical connection portions 22a and 23a are provided on the 1 st outer wall body 21 a. The electrical connection portions 22a and 23a are arranged on the 1 st outer wall 21a at intervals. For example, the 1 st terminal fitting 22 and the 2 nd terminal fitting 23 shown here are arranged at intervals from each other, and the end portions are respectively projected from the outer wall surface of the 1 st outer wall body 21a toward the orthogonal direction orthogonal to the outer wall surface. The 1 st terminal fitting 22 and the 2 nd terminal fitting 23 each use an end portion thereof in a protruding state as the electrical connection portion 22a, 23 a. For example, the 1 st terminal fitting 22 and the 2 nd terminal fitting 23 each have a cylindrical body whose protruding direction from the outer wall surface of the 1 st outer wall body 21a is the cylindrical axis direction, and one end portion in the cylindrical axis direction of the cylindrical body is protruded from the outer wall surface of the 1 st outer wall body 21a, whereby the annular end portions are used as the electrical connection portions 22a, 23 a.
In the electronic component 20, the electrical connection portion 22a of the 1 st terminal fitting 22 is physically and electrically connected to the 1 st conductor 11 of the electrical connection member 10. For example, in the cylindrical body of the 1 st terminal fitting 22, a female screw portion (not shown) is formed on an inner peripheral surface thereof. The 1 st conductor 11 is provided with a circular through hole 11a (fig. 1, 2, 4, 6, and 8) arranged concentrically with the electrical connection portion 22 a. Here, when the 1 st conductor 11 is disposed to face the 1 st outer wall body 21a, the peripheral edge of the through hole 11a of the 1 st conductor 11 is brought into contact with the annular end surface of the electrical connection portion 22 a. The through hole 11a and the electrical connection portion 22a are disposed concentrically, and a male screw portion (not shown) inserted into the through hole 11a is screwed into the cylindrical body, whereby the 1 st conductor 11 and the 1 st terminal fitting 22 are physically and electrically connected.
Similarly to the electrical connection portion 22a, the electrical connection portion 23a of the 2 nd terminal fitting 23 is physically and electrically connected to the electrical connection portion 23a of the 2 nd terminal fitting 23 by, for example, screwing the terminal fitting (not shown) at the end of the wire to the female screw portion of the cylindrical body by the male screw portion (not shown).
The frame 30 is formed of an insulating material such as synthetic resin. Although not shown, the housing 30 is a housing box formed by assembling a plurality of divided housings, and houses the electrical connection member 10 and the electronic component 20. The housing 30 has a1 st housing chamber 31 for housing the electrical connection member 10 and a 2 nd housing chamber 32 for housing the electronic component 20 (fig. 1 to 3 and 5 to 7). In the housing 30, a1 st housing chamber 31 and a 2 nd housing chamber 32 are formed in one of the plurality of divided housings. For example, the frame 30 is assembled by: a1 st division frame (so-called frame) having 2 openings arranged to face each other and having a1 st housing chamber 31 and a 2 nd housing chamber 32 formed in the space inside thereof; a 2 nd division frame body (so-called upper cover) which closes one opening of the 1 st division frame body; and a 3 rd division frame body (so-called lower cover) which closes the other opening of the 1 st division frame body.
The 1 st accommodation chamber 31 is a compartment that accommodates the electrical connection member 10 at an accommodation completion position (hereinafter referred to as "1 st accommodation completion position") (fig. 4 to 7). The 1 st housing chamber 31 has a1 st housing portion 31a for housing the 1 st conductor 11 and a 2 nd housing portion 31b for housing the 2 nd conductor 12 (fig. 1 and 3 to 7). The 1 st and 2 nd accommodation parts 31a and 31b are arranged orthogonally in an L-shape, and extend in orthogonal directions in the respective compartments with the intersection of the parts as a starting point.
Here, the electrical connection member 10 is inserted into the 1 st accommodation chamber 31 in the orthogonal direction orthogonal to the extending direction of the 1 st conductor 11 from the intersection and the extending direction of the 2 nd conductor 12 from the intersection. Thus, the 1 st housing portion 31a and the 2 nd housing portion 31b are formed so that the orthogonal direction orthogonal to the extending direction extending from the intersection portion of the two portions becomes the insertion direction of the electrical connection member 10. In the 1 st housing chamber 31, when the housing work of the electrical connection member 10 is completed, the orthogonal direction orthogonal to the extending direction of the 1 st housing portion 31a and the 2 nd housing portion 31b is made to coincide with the orthogonal direction orthogonal to the extending direction of the 1 st conductor 11 and the 2 nd conductor 12. In the 1 st housing chamber 31, the housing work completion position is a housing completion position (1 st housing completion position) of the electrical connection member 10.
The 2 nd accommodating chamber 32 is a compartment (fig. 4 to 7) that accommodates the electronic component 20 at an accommodating completion position (hereinafter referred to as "2 nd accommodating completion position"). The 2 nd accommodation completion position refers to a completion position of the accommodation work of the electronic component 20, and refers to a position where: the 1 st outer wall 21a is disposed to face the 1 st conductor 11 of the electrical connection member 10 at the 1 st accommodation completion position, and the 2 nd outer wall 21b is disposed to face the 2 nd conductor 12 of the electrical connection member 10 at the 1 st accommodation completion position. In this example, the following positions become the accommodation completion position (2 nd accommodation completion position): the outer wall surface of the 1 st outer wall body 21a is disposed facing the plane of the 1 st conductor 11 at the 1 st housing completion position with a space therebetween in a parallel state, and the outer wall surface of the 2 nd outer wall body 21b is disposed facing the plane of the 2 nd conductor 12 at the 1 st housing completion position with a space therebetween in a parallel state.
The 2 nd accommodating chamber 32 and the 1 st accommodating portion 31a of the 1 st accommodating chamber 31 communicate with each other without a space therebetween so that the 1 st conductor 11 at the 1 st accommodating completion position is in contact with the electrical connection portion 22a of the 1 st outer wall body 21a at the 2 nd accommodating completion position. On the other hand, in the electrical connection member 10 and the electronic component 20, if the 2 nd conductor 12 is inclined toward the 2 nd outer wall body 21b before the 1 st conductor 11 and the electrical connection portion 22a are screwed, it is necessary to perform position adjustment until the through hole 11a of the 1 st conductor 11 and the electrical connection portion 22a are arranged at concentric positions. Therefore, in the housing 30, a partition 33 (fig. 1 to 3 and 5 to 7) is provided between the 2 nd conductor 12 at the 1 st housing completion position and the 2 nd outer wall 21b at the 2 nd housing completion position so that the 2 nd conductor 12 does not incline toward the 2 nd outer wall 21 b.
The 2 nd accommodating chamber 32 has a seating surface 32a (fig. 1 to 3 and 7) on which the electronic component 20 is seated in the 2 nd accommodating completion position. Here, the 3 rd outer wall 21c connected to the 1 st outer wall 21a and the 2 nd outer wall 21b is disposed on the disposition surface 32 a. The 3 rd outer wall body 21c is disposed on the insertion direction side of the electronic component 20 itself inserted to the 2 nd accommodation completion position.
Although not shown, the housing 30 may be formed with: a housing chamber housing other electrical connection parts 10, a housing chamber housing other electrical connection parts different from the electrical connection parts 10, a housing chamber housing other electronic components 20, a housing chamber housing other electronic components different from the electronic components 20, and the like.
However, in this electrical connection box 1, if the electronic component 20 is to be inserted to the 2 nd accommodation completion position in a state where the electrical connection member 10 is accommodated in the 1 st accommodation completion position, or the electrical connection member 10 is to be inserted to the 1 st accommodation completion position in a state where the electronic component 20 is accommodated in the 2 nd accommodation completion position, there is a possibility that the 1 st conductor 11 may come into contact with the electronic component 20 (e.g., the electrical connection portion 22a) during this insertion work. Even if the dimensional variations of the electrical connection member 10, the electronic component 20, and the housing 30 are within the predetermined tolerance ranges, or even if the assembly variations of the electrical connection member 10 and the housing 30 and the assembly variations of the electronic component 20 and the housing 30 are within the predetermined tolerance ranges, there is a possibility that the contact during such an assembly operation occurs. Therefore, when the 1 st conductor 11 is brought into contact with the electronic component 20 and is locked during the insertion work, at least one process such as an operation of accommodating the electrical connection member 10 and the electronic component 20 needs to be performed again.
Therefore, in order to improve the workability of accommodating the electrical connection member 10 and the electronic component 20, the electrical connection box 1 is configured as follows.
In the electrical connection box 1, the electrical connection member 10 is temporarily held in the housing 30 at a position and in a state where the accommodation work of the electrical connection member 10 and the electronic component 20 does not need to be performed again, and the electrical connection member 10 is displaced from the state of the temporarily held position to the state of the 1 st accommodation completion position in conjunction with the operation of the accommodation work of the electronic component 20 toward the 2 nd accommodation completion position. The temporary holding position of the electrical connection member 10 means: the 1 st conductor 11, which is a part of the peripheral edge of the insertion port of the electronic component 20, is separated from the insertion path of the electronic component 20, thereby expanding the insertion port to the 1 st conductor 11 side. In the electrical junction box 1, the insertion port of the electronic component 20 is expanded in this manner, so that the electronic component 20 is not locked to the 1 st conductor 11 during the insertion. In the electrical connection box 1, as the electronic component 20 is inserted toward the 2 nd accommodation completion position, the electrical connection member 10 is displaced from the state of the temporary holding position to the state of the 1 st accommodation completion position while being pushed by the electronic component 20. For example, in the electrical connection member 10 at the temporary holding position, the 1 st conductor 11 is separated from the insertion path of the electronic component 20 so that the electrical connection portion 22a does not contact the 1 st conductor 11 at least until the electrical connection portion 22a protruding from the 1 st outer wall body 21a is disposed facing the 1 st conductor 11 with a gap therebetween.
First, the electrical connection box 1 includes a temporary holding mechanism 40, and the temporary holding mechanism 40 can tilt the electrical connection member 10 with respect to the 1 st accommodation completion position, raise the free end side of the 2 nd conductor 12 to a temporary holding position higher than the 1 st conductor 11, and temporarily hold the electrical connection member 10 in the housing 30 (fig. 2, 3, and 5 to 7). At the temporary holding position, the free end side of the 2 nd conductor 12 is raised higher than the 1 st conductor 11 and the intersection of the 1 st conductor 11 and the 2 nd conductor 12, whereby the end opposite to the insertion direction of the 1 st conductor 11 is separated from the insertion track of the electronic component 20 (fig. 2 and 3).
In the electrical connection box 1, the electrical connection member 10 is temporarily held in the housing 30 by the temporary holding mechanism 40 at the temporary holding position while the electrical connection member 10 is inserted into the 1 st accommodation chamber 31. Thus, in the electrical junction box 1, the 1 st conductor 11 side of the insertion port of the electronic component 20 formed by the electrical connection member 10 is expanded as compared with the insertion port of the electronic component 20 formed by the electrical connection member 10 in the 1 st accommodation completion position. In the electrical junction box 1, when the electrical connection member 10 is in the state of being temporarily held in position, the electronic component 20 is inserted from an insertion opening formed partially by the electrical connection member 10. In the electrical junction box 1, the insertion opening is expanded on the 1 st conductor 11 side, and the electronic component 20 inserted from the insertion opening is less likely to be locked to the 1 st conductor 11, and the electronic component 20 can be inserted to the 2 nd accommodation completion position.
Further, in the electrical connection box 1, the electrical connection member 10 has the pushed body 13 on the free end side of the 2 nd conductor 12, and the pushed body 13 is pushed by the electronic component 20 from the temporary holding position to the 1 st accommodation completion position (fig. 1 to 3 and 5 to 8) along the insertion trajectory of the electronic component 20 to the 2 nd accommodation completion position. In other words, the electrical connection member 10 has the pushed body 13 on the free end side of the 2 nd electrical conductor 12 and on the insertion trajectory of the electronic component 20 to the 2 nd accommodation completion position, the pushed body 13 being pushed by the electronic component 20 from the temporary holding position to the 1 st accommodation completion position. Thus, in the electrical connection box 1, when the electronic component 20 inserted from the insertion port is inserted, the pushed body 13 abuts on the electronic component 20, and since the insertion of the electronic component 20 is further performed, the pushed body 13 is pushed by the electronic component 20, and the electrical connection member 10 is displaced from the temporary holding position to the 1 st accommodation completion position.
Thus, although the electrical connection box 1 of the present embodiment needs to temporarily hold the electrical connection member 10 at the temporary holding position, the electrical connection member 10 can be displaced from the temporary holding position to the 1 st accommodation completion position in conjunction with the operation of accommodating the electronic component 20. Therefore, compared to the configuration in which the electrical connection member 10 is inserted to the 1 st housing completion position without being temporarily held at the temporary holding position, the electrical connection box 1 can suppress a reduction in the workability of housing the electrical connection member 10 in the housing 30. In addition, in the electrical connection box 1 of the present embodiment, since the electronic component 20 can be inserted to the 2 nd accommodation completion position without being locked to the electrical connection member 10, it is possible to suppress the occurrence of a situation in which the accommodation work of the electrical connection member 10 and the electronic component 20 is newly performed. Therefore, the electrical connection box 1 of the present embodiment can improve the workability of accommodating the electrical connection member 10 and the electronic component 20.
Specifically, the temporary holding mechanism 40 is provided in at least one of the electrical connection member 10 and the housing 30. For example, the temporary holding mechanism 40 may be a protrusion provided on either one of the electrical connection member 10 and the housing 30, or may be a mechanism in which protrusions provided on both the electrical connection member 10 and the housing 30 are engaged with each other. Here, the temporary holding mechanism 40 provided in the housing 30 is exemplified.
The temporary holding mechanism 40 includes a temporary holding body 41 protruding from a wall surface forming the 2 nd accommodating portion 31 b. The wall surface forming the 2 nd accommodating portion 31b means: a wall surface (bottom surface 31c) of the 1 st housing chamber 31, a wall surface of the partition 33, a wall surface of the frame 30 disposed to face the wall surface of the partition 33, and the like. In this example, the temporary holding body 41 is made to protrude from the wall surface (bottom surface 31c) of the 1 st accommodation chamber 31. The bottom surface 31c of the 1 st accommodation chamber 31 and the installation surface 32a of the 2 nd accommodation chamber 32 are formed on the same plane. The temporary holding member 41 shown here has a rectangular top surface 41a (fig. 2, 3, 6, and 7) parallel to the bottom surface 31 c. The temporary holder 41 is configured to support the 2 nd conductor 12 of the electrical connection component 10 inserted into the 1 st accommodation chamber 31 at a temporary holding position. Thus, the temporary holding body 41 protrudes from the wall surface (bottom surface 31c) of the 2 nd accommodating portion 31b of the 1 st accommodating chamber 31. The temporary holder 41 is formed as a protrusion for supporting the supported portion 12a between the free end side and the fixed end side of the end portion 12a of the 2 nd conductor 12 viewed in the insertion direction of the electronic component 20 to the 2 nd accommodation completion position at the temporary holding position1(FIGS. 2 and 3). Supported part 12a1Is a part between the free end side and the fixed end side of the end portion 12a of the 2 nd conductor 12.
The inclination angle of the electrical connection member 10 at the temporary holding position with respect to the 2 nd accommodation completion position is set to, for example: when the electronic component 20 is inserted from the insertion opening, the electrical connection portion 22a of the electronic component 20 is not brought into contact with the 1 st conductor 11 until the electrical connection portion 22a is disposed to face the 1 st conductor 11 with a gap therebetween.
Here, in terms of performing the operation of accommodating the electronic component 20, it is preferable that the electric connection member 10 maintains a state of temporarily holding a position if the electronic component 20 is not accommodated in the 2 nd accommodation chamber 32 when the electric connection member 10 is accommodated in the 1 st accommodation chamber 31. Then, the temporary holding body 41 is formed such that, for example, the center of gravity of the electrical connection member 10 is located at the supported portion 12a of the 1 st conductor 11 and the 2 nd conductor 121The holding body therebetween is sufficient. Thus, when the electrical connection member 10 is inserted into the 1 st accommodation chamber 31, the free end side of the 2 nd conductor 12 is raised to a temporary holding position higher than the 1 st conductor 11, and the state is held.
The electrical connection member 10 locks the 1 st conductor 11 on the wall surface of the 1 st housing chamber 31 when at the temporary holding position. For example, when the electrical connection member 10 is in the temporary holding position, the 1 st housing chamber 31 illustrated in the example has a locking surface 31d (fig. 3) that locks the end portion 11b of the 1 st conductor 11 on the wall surface of the 1 st housing portion 31a when viewed from the insertion direction of the electronic component 20. Here, an inclined surface along the end surface of the end portion 11b at the temporary holding position is formed on the bottom surface 31c of the 1 st accommodating portion 31a, and this inclined surface is used as the locking surface 31 d.
The pushed body 13 shown in the example is formed as a pushed body which is disposed to face the 3 rd outer wall 21c of the electronic component 20 and pushed by the 3 rd outer wall 21 c. The pushed body 13 protrudes from the free end side of the end portion 12a of the 2 nd conductor 12 to a position where it can be pushed by the 3 rd outer wall body 21 c. Here, the pushed body 13 is formed in an L shape having a1 st piece 13a and a 2 nd piece 13b orthogonally arranged (fig. 8). The 1 st piece 13a is a rectangular piece protruding from the end 12a of the 2 nd conductor 12 on the same plane. The 2 nd piece 13b is a rectangular piece that protrudes orthogonally from the 1 st piece 13a to a position where it can be pushed by the 3 rd outer wall 21 c. In the pushed body 13, one flat surface of the 2 nd piece 13b is arranged to face the 3 rd outer wall body 21c, and the flat surface is pushed by the 3 rd outer wall body 21 c.
In this example, since the L-shaped pushed body 13 is used, the housing 30 is provided with a recess 34, and the recess 34 accommodates the pushed body 13 when the electrical connection member 10 is located at the 1 st accommodation completion position (fig. 1 to 3 and 5 to 7). The recess 34 is formed in a shape in which the bottom surface 31c of the 2 nd housing part 31b of the 1 st housing chamber 31 is recessed and the mounting surface 32a of the 2 nd housing chamber 32 is recessed.
In the exemplary electrical connection box 1, the electrical connection member 10 is inserted into the 1 st accommodation chamber 31, whereby the electrical connection member 10 is temporarily held by the temporary holding body 41 and the locking surface 31 d. Here, the electrical connection member 10 is supported in an inclined state by the locking surface 31d and 1 side portion of the top surface 41a of the temporary holding body 41 on the locking surface 31d side. In the electrical junction box 1, the electrical connection member 10 in the temporarily held state expands the insertion port of the electronic component 20 toward the 1 st conductor 11. Thus, in the electrical junction box 1, the electrical connection portion 22a of the electronic component 20 inserted from the insertion opening in the protruding state is less likely to be caught by the 1 st conductor 11, and the accommodating operation of the electronic component 20 to the 2 nd accommodating completion position can be easily continued. In the electrical connection box 1, the 3 rd outer wall 21c of the electronic component 20 pushes the 2 nd piece 13b of the pushed body 13 simultaneously with the accommodation operation of the electronic component 20, and the electrical connection member 10 is displaced from the temporary holding position. In the electrical connection box 1, when the electronic component 20 reaches the 2 nd accommodation completion position, the electrical connection member 10 becomes the 1 st accommodation completion position. In this example, when the electrical connection member 10 reaches the 1 st accommodation completion position, the 2 nd conductor 12 is separated from the top surface 41a of the temporary holder 41. However, when the electrical connection member 10 is at the 1 st accommodation completion position, the 2 nd conductor 12 may be set on the top surface 41a of the temporary holder 41.
Thus, as described above, the electrical connection box 1 can be inserted to the 2 nd accommodation completion position without locking the electronic component 20 to the electrical connection member 10 while suppressing a decrease in the accommodation workability of the electrical connection member 10 in the housing 30. Therefore, the electrical connection box 1 can improve the workability of accommodating the electrical connection member 10 and the electronic component 20.
Here, the temporary holding mechanism 40 may be configured as follows. The temporary holding mechanism 40 shown here includes a temporary holding body 42 (fig. 9) protruding from the wall surface (bottom surface 31c) of the 1 st accommodation chamber 31. As with the temporary holder 41 described above, the temporary holder 42 is configured to support the 2 nd conductor 12 of the electrical connection component 10 inserted into the 1 st accommodation chamber 31 at the temporary holding position. Thus, the temporary holding body 42 protrudes from the wall surface (bottom surface 31c) of the 2 nd accommodating part 31b of the 1 st accommodating chamber 31, as in the above temporary holding body 41. The temporary holding body 42 is formed as an elastic deformable body that elastically deforms to support the supported portion 12a when in the temporary holding position1The supported portion 12a1 is located between the free end side and the fixed end side of the end portion 12a of the 2 nd conductor 12 as viewed in the insertion direction of the electronic component 20 to the 2 nd accommodation completion position. The exemplary temporary holding member 42 is formed in an elastically deformable rectangular sheet shape supported in a cantilever state on the bottom surface 31c of the 2 nd accommodating portion 31 b.
In the electrical connection box 1 in this case, by inserting the electrical connection member 10 into the 1 st accommodation chamber 31, the electrical connection member 10 is brought into a temporarily held state in which it is supported in an inclined state by the temporarily holding body 42 and the locking surface 31 d. This allows the electrical connection box 1 to obtain the same effect as that obtained when the temporary holder 41 is used.
As with the above temporary holding body 41, the temporary holding body 42 may be any holding body that protrudes from the wall surface forming the 2 nd accommodating portion 31 b. Therefore, the temporary holder 42 may be provided on a wall surface of the partition 33, a wall surface of the frame 30 disposed to face the wall surface of the partition 33, or the like.
