Description

Technical Field

[0001] The present invention relates to a manufacturing method for an electrical connection box including a main body portion having a peripheral wall defining an internal space, a selected component selected from a plurality of holding components and constituting a part of the peripheral wall, and a wire with a terminal assembled to the selected component.

Background Art

[0002] Conventionally, an electrical connection box (for example, a relay box) mounted on a vehicle has been proposed (for example, refer to Patent Document 1). In this type of electrical connection box, an opening may be provided in the frame so as to communicate the inside and outside of the case-shaped frame, and a side cover may be assembled to close the opening. Such an opening is generally used when introducing a wire connected to an external device (for example, an engine, a converter, a battery, etc.) from the outside to the inside of the frame.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, the side cover mentioned above may be used to hold various electrical components (for example, wires with terminals). For example, when a wire with a bent terminal is to be held in the side cover, it is conceivable to provide an annular holding part on the inner wall surface of the side cover and secure the terminal by passing the bent part of the terminal through the ring of this holding part. However, in this case, due to the shape of the bent part, when passing the terminal through the ring of the holding part, it becomes necessary to rotate the terminal around the bend. Such work is cumbersome, and providing a gap (so-called clearance) between the holding part and the side cover to allow for terminal rotation can cause displacement of the terminal (so-called misalignment) after assembly. Furthermore, if the direction in which the terminal extends from the side cover differs depending on the specifications of the electrical junction box, manufacturing side covers of different shapes for each specification can increase the manufacturing cost of the electrical junction box.

[0005] One of the objectives of the present invention is to provide a manufacturing method for producing an electrical junction box that is excellent in productivity and manufacturing cost, as well as in the holding performance of wires with terminals. [Means for solving the problem]

[0006] To achieve the aforementioned objectives, the method for manufacturing an electrical junction box according to the present invention is characterized by the following:

[0007] A manufacturing method for producing an electrical junction box having a main body having a peripheral wall defining an internal space, a selectable component selected from a plurality of holding components to constitute a part of the peripheral wall, and a terminal-equipped electric wire to be assembled to the selectable component, The aforementioned wire with terminals is It has a terminal having a plate-shaped terminal portion with a bent portion, and an electric wire connected to the terminal, The aforementioned selected component is The terminal has a first retaining surface facing one side of the terminal portion, and a wire retaining portion for holding the wire, and all of the plurality of retaining parts have a common first part, The first component is assembled to a second retaining surface that faces the other side of the terminal portion, and each of the plurality of retaining components has a different second component, The manufacturing method is A step of selecting one of the plurality of holding parts, The steps include attaching the first component to the wire with the terminal, The process includes attaching the first component, which is attached to the terminal-equipped wire, to the second component corresponding to the selected component. This is a method for manufacturing an electrical junction box. [Effects of the Invention]

[0008] According to the present invention's method for manufacturing an electrical junction box, an electrical junction box is manufactured using a selectable component chosen from a plurality of retaining components (e.g., a side cover). The selectable component comprises a first component and a second component. The first component is common to all of the plurality of retaining components, while the second component differs for each of the plurality of retaining components. The electrical junction box is then manufactured by attaching the first component, which is mounted on a wire with a terminal, to the second component corresponding to the selectable component. As a result, since the first component is a common component, the production cost of the selectable component can be reduced compared to the case where both the first component and the second component differ for each selectable component. Furthermore, when the first component is assembled to the second component, the terminal portion of the wire with a terminal is sandwiched between the first retaining surface of the first component and the second retaining surface of the second component. When assembling the terminal to the first component, if a sufficiently large clearance is provided between the first component and the terminal, the terminal can be easily assembled to the first component. Furthermore, if the first and second parts are designed such that when the first part is assembled to the second part, the first retaining surface of the first part contacts (or is positioned close to) the terminal, and the second retaining surface of the second part contacts (or is positioned close to) the terminal, then the displacement of the terminal can be reduced when assembling the first part to the second part. By reducing the displacement of the terminal, the workability when connecting the terminal portion of the wire with a terminal to terminals located in the internal space of an electrical junction box is also improved. Therefore, the manufacturing method of the present invention is excellent in terms of productivity and manufacturing cost, as well as in the holding performance of the wire with a terminal.

BEST MODE FOR CARRYING OUT THE INVENTION

[0011] <Embodiment> Hereinafter, the electrical connection box 1 according to the embodiment of the present invention shown in FIG. 1 will be described with reference to the drawings. The electrical connection box 1 is typically a relay box mounted on a vehicle and housing electronic components such as relays. As shown in FIG. 1, the electrical connection box 1 includes a main body portion 10 having a peripheral wall 11 defining an internal space, a selection cover 20Z assembled to the notch portion 12 of the main body portion 10 and constituting a part of the peripheral wall 11, and a wired terminal 30 assembled to the selection cover 20Z. The selection cover 20Z is a side cover selected from the side cover 20A (see FIG. 3), the side cover 20B (see FIG. 4), and the side cover 20C (see FIG. 5), as will be described later. As can be understood from FIGS. 3 to 5, each of the side covers 20A to 20C has a different extending direction of the tip portion 53 of the terminal 50 when the wired terminal 30 is assembled. In the example shown in FIG. 1, the side cover 20A is selected as the selection cover 20Z. Although not shown, the electrical connection box 1 also includes an upper cover assembled above the main body portion 10 so as to close the upper end opening of the main body portion 10, and a lower cover assembled below the main body portion 10 so as to close the lower end opening of the main body portion 10. The main body portion 10, the selection cover 20Z, the upper cover, and the lower cover constituting the electrical connection box 1 are all resin molded bodies.

[0012] Hereinafter, for the convenience of explanation, as shown in FIG. 1 and the like, the "inner and outer direction", "front and rear direction", "up and down direction", "inner", "outer", "front", "rear", "up" and "down" are defined. The "inner and outer direction", "front and rear direction", and "up and down direction" are orthogonal to each other. The "inner" side and the "outer" side respectively correspond to the inner side and the outer side of the electrical connection box 1 (main body portion 10), and the "front and rear direction" corresponds to the circumferential direction of the peripheral wall 11 of the portion of the main body portion 10 where the selection cover 20Z is assembled. The "up and down direction" corresponds to the up and down direction of the vehicle when the electrical connection box 1 is mounted on the vehicle. Hereinafter, the configurations of the respective components constituting the electrical connection box 1 will be described in order.

[0013] First, the wire 30 with terminals will be described. As shown in FIG. 7 and the like, the wire 30 with terminals is composed of a wire 40 in which a conductor core wire is covered with an insulating coating, and a metal terminal 50 fixed to the end of the wire 40 and electrically connected to the conductor core wire of the wire 40. The terminal 50 includes a plate-like terminal portion 51 that extends in a substantially L-shaped bent manner. Specifically, the plate-like terminal portion 51 is composed of a base portion 52 that extends in a flat plate shape in the up and down direction, a tip portion 53 that extends in a flat plate shape in a direction orthogonal to the up and down direction, and a bent portion 54 that extends while being bent in an arc shape and connects the upper end portion of the base portion 52 and the proximal end side end portion of the tip portion 53. A through hole 55 penetrating in the plate thickness direction (up and down direction) is formed in the tip portion 53 (see also FIG. 1, FIG. 2, etc.).

[0014] Next, the main body portion 10 will be described. As shown in FIG. 1, the peripheral wall 11 that defines the internal space of the main body portion 10 has a substantially rectangular cylindrical shape that extends in the up and down direction. Various electronic components (not shown) such as relays are accommodated in the internal space of the main body portion 10. A notch portion 12 is formed in a part of the circumferential direction of the peripheral wall 11, where the peripheral wall 11 is cut out so as to divide the peripheral wall 11 in the circumferential direction. The notch portion 12 constitutes a rectangular opening. A plate-like portion 71 of the selection cover 20Z described later is to be assembled to the notch portion 12.

[0015] Inside the main body 10 (peripheral wall 11), in the example shown in Figure 1, a retaining member 13 is fixedly positioned adjacent to the front of the notch 12. A metal stud bolt 14 protrudes upward from the upper end of the retaining member 13 and extends vertically. The stud bolt 14 will be inserted through the through hole 55 of the terminal 50 (see Figure 1). In the example shown in Figure 1, when the selection cover 20Z is assembled to the notch 12, a side cover 20A is selected as the selection cover 20Z so that the tip 53 of the terminal 50 extends forward, allowing the through hole 55 of the terminal 50 to be inserted through the stud bolt 14 extending from the retaining member 13 located in front of the notch 12. In this way, the selection cover 20Z is selected from the side covers 20A to 20C based on the direction in which the tip 53 of the terminal 50 extends from the selection cover Z toward the stud bolt 14.

[0016] Next, we will describe the side covers 20A to 20C, which are candidates for the selected cover 20Z. As shown in Figures 3 to 5, each of the side covers 20A to 20C consists of a first component 60 common to all side covers 20A to 20C, and second components 70A to 70C, which are individually corresponding to each of the side covers 20A to 20C. The second components 70A to 70C differ in shape from each other. A wire with terminals 30 is assembled to the first component 60. Each of the second components 70A to 70C is assembled to the first component 60 with the wire with terminals 30 already attached. In this case, the first part 60 is assembled to the second part 70A with the tip 53 of the terminal 50 extending forward (see Figure 3), the first part 60 is assembled to the second part 70B with the tip 53 of the terminal 50 extending inward (see Figure 4), and the first part 60 is assembled to the second part 70C with the tip 53 of the terminal 50 extending rearward (see Figure 5). Thus, the different assembly directions of the first part 60 to the second parts 70A to 70C result in different extension directions of the tip 53 of the terminal 50 when assembled to the side covers 20A to 20C.

[0017] Below, we will first describe the first component 60 and the second component 70A that constitute the side cover 20A, assuming that the selection cover 20Z is assembled to the notch 12 of the main body 10, which is provided so that the retaining member 13 (stud bolt 14) is located on the front side of the notch 12, as shown in Figure 1; that is, a side cover 20A (60+70A) is selected as the selection cover 20Z so that the tip 53 of the terminal 50 extends forward in order to insert the through hole 55 of the terminal 50 into the stud bolt 14 located on the front side of the notch 12.

[0018] First, let's describe the first component 60. As shown in Figures 3 to 5, the first component 60 consists of a pair of side wall portions 61 that are spaced apart and facing each other in the inward and outward directions, and a connecting wall portion 62 that connects the rear edges of the pair of side wall portions 61 in the inward and outward directions and extends in the vertical direction. Overall, it has a roughly rectangular box shape that opens forward and upward and extends in the vertical direction. The electric wire 30 with terminals will be housed in the internal space of the first component 60.

[0019] The upper regions of the front edges of a pair of side wall portions 61 are connected in the inward and outward directions by a flat connecting plate portion 63 that extends in a band-like shape in the inward and outward directions. Above the connecting plate portion 63, a bent plate portion 64 is provided, which extends while bending in a quarter-circle shape so that the direction of extension gradually changes from upward to forward (see Figures 7 and 8). The inward and outward edges of the bent plate portion 64 are connected to a pair of extension portions 61a that extend from the upper front corners of the pair of side wall portions 61. When the terminal-equipped electric wire 30 is assembled to the first component 60, the pair of extension portions 61a are positioned to sandwich the bent portion 54 of the terminal 50 in the inward and outward directions (see Figure 3), and the outer surface of the bent plate portion 64 faces the inner surface 54a of the bent portion 54 of the terminal 50 (see Figure 8). Hereinafter, the outer surface of the bent plate portion 64 will be referred to as the "holding surface 65". Here, the retaining surface 65 corresponds to the "first retaining surface" of the present invention.

[0020] As shown in Figure 3, the upper end of the first part 60 has a roughly rectangular recess 66 that is recessed downward, surrounded by the upper edges of a pair of side wall portions 61, the upper edge of the connecting wall portion 62, and the bent plate portion 64. Furthermore, in accordance with the fact that the first part 60 is assembled to the second part 70A with the tip portion 53 of the terminal 50 extending forward, the stepped portions 67A, 68A, and recess 69A provided on the first part 60 engage with the second part 70A. Specifically, as shown in Figures 3 to 5, a stepped portion 67A with a downward-facing stepped surface is formed at the lower end of the front edge of the outer side wall portion 61 of the first part 60. As shown in Figures 4 and 5, a stepped portion 68A with an upward-facing stepped surface is formed in the lower region of the connecting wall portion 62 of the first part 60. As shown in Figure 5, a recess 69A is formed in the upper region of the connecting wall portion 62 of the first part 60, which is recessed toward the front side (towards the internal space of the first part 60). When the first part 60 is assembled to the second part 70A, the protrusion 75 of the second part 70A, which will be described later, is fitted into the recess 66 of the first part 60 (see Figure 7), the stepped portion 67A of the first part 60 and the stepped portion 77 of the second part 70A, which will be described later, engage (see Figures 7 and 10), the stepped portion 68A of the first part 60 and the stepped portion 78 of the second part 70A, which will be described later, engage (see Figure 10), and the locking piece 79 of the second part 70A, which will be described later, engages with the outer opening edge 69Aa of the recess 69A of the first part 60 (see Figure 9).

[0021] To assemble the terminal-equipped wire 30 to the first component 60 described above, first, while maintaining the orientation of the terminal 50 of the terminal-equipped wire 30 such that the tip 53 protrudes upward and the wire 40 extends forward from the first component 60, the tip 53 is moved from below into the internal space of the first component 60 through the lower end opening or front end opening of the roughly rectangular box-shaped first component 60, and moved to a position adjacent to the rear side of the bent plate portion 64 and protruding upward from the upper end opening of the first component 60. Next, the terminal 50 is rotated 90 degrees counterclockwise when viewed from the inside in the inward-outward direction. In this example, there are no interference points between the first component 60 and the terminal 50 that would hinder such rotation of the terminal 50, so the terminal 50 can be easily rotated relative to the first component 60. As a result, as shown in Figures 3, 7, and 8, the bent portion 54 of the terminal 50 is sandwiched inward and outward by a pair of extended portions 61a of the first component 60, the inner surface 54a of the bent portion 54 of the terminal 50 faces the holding surface 65 of the first component 60, the tip portion 53 of the terminal 50 is exposed to the outside so as to protrude forward from the upper end of the first component 60, the base portion 52 of the terminal 50 is located within the internal space of the first component 60, and the wire 40 of the terminal-attached wire 30 extends outward downward from the lower end opening of the first component 60. The wire 40 extending downward from the lower end opening of the first component 60 and the extended piece 62a extending further downward from the lower end of the connecting wall portion 62 of the first component 60 are wrapped together with the tape 80 (see Figure 3, etc.). This fixes the electric wire 40 (i.e., the electric wire 30 with terminals) to the extension piece 62a (i.e., the first component 60), completing the assembly of the electric wire 30 with terminals to the first component 60.

[0022] Next, the second component 70A will be described. As shown in Figure 3, the second component 70A has a plate-shaped portion 71. The plate-shaped portion 71 will be assembled into the notch 12 of the peripheral wall 11 of the main body portion 10 (see Figure 1). For this reason, the plate-shaped portion 71 has a rectangular flat plate shape that corresponds to the opening shape of the notch 12 of the peripheral wall 11. The first component 60, to which the terminal-equipped electric wire 30 is assembled, will be assembled to the inner surface of the plate-shaped portion 71. For this reason, a first component housing portion 72 for housing the first component 60 is provided on the inner surface of the plate-shaped portion 71. As shown in Figure 3, the first component housing section 72 is composed of a pair of side wall sections 73 that protrude from the inner surface of the plate-shaped section 71 and are spaced apart and facing each other in the front-rear direction, and an upper wall section 74 that protrudes from the inner surface of the plate-shaped section 71 and connects the upper edges of the pair of side wall sections 73. Overall, it has a roughly rectangular box shape that opens inward and downward and extends in the vertical direction.

[0023] As shown in Figure 3, the protrusion height of the front side wall portion 73 of the pair of side wall portions 73 from the plate-like portion 71 gradually decreases from the lower end of the front side wall portion 73 upwards. Therefore, the protruding end surface of the front side wall portion 73 generally constitutes an inclined surface 73a that slopes outwards as it moves upwards. As will be described later, the inclined surface 73a serves to guide the first part 60 when assembling the first part 60 to the second part 70A. The lower surface of the upper wall portion 74 is provided with a roughly rectangular protrusion 75 that protrudes downwards (into the interior of the first part housing portion 72) corresponding to the recess 66 of the first part 60. In addition, the upper wall portion 74 is provided with an extended plate portion 74a that extends further forward from the front edge of the upper wall portion 74. When the first component 60, to which the terminal-equipped electric wire 30 is assembled, is housed in the first component housing 72, as shown in Figures 7 and 8, the front wall surface of the protrusion 75 (a plane extending in the vertical and inward / outward directions) and the lower surface of the extension plate portion 74a (a plane extending in the front-rear and inward / outward directions) face the outer surface 54b of the bent portion 54. Hereinafter, the front wall surface of the protrusion 75 and the lower surface of the extension plate portion 74a will be referred to as the "holding surface 76". Hereinafter, the holding surface 76 corresponds to the "second holding surface" of the present invention.

[0024] On the rear side surface (the inner surface of the first component housing 72) of the front side wall portion 73 of the second component 70A, a stepped portion 77 with an upward-facing stepped surface is formed, corresponding to the stepped portion 67A of the first component 60, as shown in Figures 7 and 10. On the front side surface (the inner surface of the first component housing 72) of the rear side wall portion 73 of the second component 70A, a stepped portion 78 with a downward-facing stepped surface is formed, corresponding to the stepped portion 68A of the first component 60, as shown in Figures 3 and 10. On the rear side wall portion 73 of the second component 70A, a cantilever-shaped locking piece 79 is cut out, corresponding to the recess 69A of the first component 60, as shown in Figures 3, 7 and 9, so as to extend inward and outward from the inner base end to the outer free end. The locking piece 79 is elastically deformable in the front-rear direction.

[0025] In order to assemble the first part 60, to which the terminal-equipped wire 30 is attached, onto the second part 70A as described above, first, the first part 60, with the tip 53 of the terminal 50 facing forward, is tilted from below so as to follow the inclined surface 73a of the second part 70A, and while guiding it along the inclined surface 73a, it is moved towards the inside of the first part housing 72, and the recess 66 of the first part 60 is engaged (hooked) onto the protrusion 75 of the second part 70A. Next, using the engagement point between the recess 66 and the protrusion 75 as a pivot point, the first part 60 is rotated clockwise relative to the second part 70A when viewed from the front in the front-rear direction, and the first part 60 is housed in the first part housing 72. As the first part 60 is rotated, as can be seen from Figure 9, in the process in which the outer side wall portion 61 of the first part 60 approaches the plate-shaped portion 71 of the second part 70A, the locking piece 79 of the second part 70A elastically deforms backward so as to be pushed aside by the outer opening edge portion 69Aa of the recess 69A of the first part 60. After the opening edge portion 69Aa overcomes the locking piece 79, the locking piece 79 elastically returns to its original position and engages with the opening edge portion 69Aa. In this way, as the rotation of the first part 60 progresses, the locking piece 79 engages with the opening edge portion 69Aa of the recess 69A, and as shown in Figure 2, the housing of the first part 60 into the first part housing portion 72 is completed. As a result, the assembly of the side cover 20A (= first part 60 + second part 70A) is completed when the first part 60, to which the terminal-equipped wire 30 is attached, is completed (see Figure 2).

[0026] When the side cover 20A (= first part 60 + second part 70A) is assembled, as shown in Figure 7, the protrusion 75 of the second part 70A is fitted into the recess 66 of the first part 60, and the outer surface of the protrusion 75 faces the inner surface of the groove of the recess 66, thereby restricting the relative movement between the first part 60 and the second part 70A. Furthermore, as shown in Figures 7 and 8, the bent portion 54 of the terminal 50 of the terminal-equipped wire 30 is sandwiched between the holding surface 65 of the first part 60 and the holding surface 76 of the second part 70A. More specifically, the holding surface 65 of the first part 60 is in contact with (or positioned in close proximity to) the inner surface 54a of the bent portion 54 of the terminal 50, and the holding surface 76 of the second part 70A is in contact with (or positioned in close proximity to) the outer surface 54b of the bent portion 54 of the terminal 50. This reduces displacement of the terminal 50. The tip 53 of the terminal 50 is exposed to the outside so as to protrude forward from the gap between the bent plate portion 64 of the first component 60 and the extended plate portion 74a of the second component 70A (see Figures 2 and 7). Furthermore, as shown in Figure 10, the downward-facing stepped surface of the stepped portion 67A of the first component 60 engages with the upward-facing stepped surface of the stepped portion 77 of the second component 70A. This restricts the relative downward movement of the first component 60 with respect to the second component 70A. Furthermore, as shown in Figure 10, the upward-facing stepped surface of the stepped portion 68A of the first component 60 engages with the downward-facing stepped surface of the stepped portion 78 of the second component 70A, and the upper edge of the outer side wall portion 61 of the first component 60 engages with the upper wall portion 74 of the second component 70A. This restricts the relative upward movement of the first component 60 with respect to the second component 70A. Furthermore, as shown in Figure 9, the locking piece 79 of the second part 70A engages with the opening edge 69Aa of the recess 69A of the first part 60. This restricts the relative rotation of the first part 60 toward the second part 70A, with the engagement point between the recess 66 and the protrusion 75 as the pivot point.

[0027] Once the assembly of the side cover 20A (= first part 60 + second part 70A) is complete, the side cover 20A with the terminal-equipped wire 30 attached is then assembled to the main body 10 as the selection cover 20Z. Specifically, as shown in Figure 1, the plate-shaped portion 71 of the selection cover 20Z with the terminal-equipped wire 30 attached is assembled to the main body 10 so that it slides downward from the top towards the notch 12 of the peripheral wall 11 of the main body 10 (see the white arrow in Figure 1), and so that the stud bolt 14 protruding upward from the retaining member 13 provided on the front side of the notch 12 is inserted through the through hole 55 provided in the tip 53 of the terminal 50 that extends forward. When the stud bolt 14 is inserted through the through hole 55 of the terminal 50, the misalignment of the terminal 50 with respect to the selection cover 20Z is reduced as described above, making it easy to insert the stud bolt 14 through the through hole 55. In this way, by assembling the plate-shaped portion 71 of the selection cover 20Z into the notch 12, the notch 12 of the peripheral wall 11 is complemented, and the selection cover 20Z constitutes a part of the peripheral wall 11. After the assembly of the selection cover 20Z to the main body 10 is completed, the assembly of the electrical connection box 1 is completed after assembling the upper cover and lower cover to the main body 10, etc. The above describes the case in which the side cover 20A (60+70A) is selected as the selection cover 20Z.

[0028] Next, we will explain the case where a selection cover 20Z is assembled to the notch 12 of the main body 10, which is provided so that the retaining member 13 (stud bolt 14) is located inside the notch 12; that is, the case where a side cover 20B (60+70B) is selected as the selection cover 20Z so that the tip 53 of the terminal 50 extends inward in order to insert the through hole 55 of the terminal 50 into the stud bolt 14 located inside the notch 12. As shown in Figure 4, in this case, a first component 60, to which a wire 30 with a terminal is assembled, is assembled to the second component 70B with the tip 53 of the terminal 50 extending inward. When describing the first component 60 below, it will be assumed that the first component 60 is oriented so that the tip 53 of the terminal 50 extends inward (as shown in Figure 4).

[0029] Regarding the second part 70B shown in Figure 4, parts that are the same as or equivalent to those of the second part 70A shown in Figure 3 are denoted by the same reference numerals as those shown in Figure 3. The second part 70B shown in Figure 4 differs from the second part 70A shown in Figure 3 in that the projection height of the front side wall portion 73 of the pair of side wall portions 73 from the plate-like portion 71 is constant in the vertical direction, similar to the rear side wall portion 73, and that the extended plate portion 74a is provided to extend further inward from the inner edge of the upper wall portion 74 in correspondence with the inward extension of the tip portion 53 of the terminal 50. In all other respects, the second part 70B has the same configuration as the second part 70A shown in Figure 3.

[0030] Furthermore, in accordance with the fact that the first component 60 is assembled to the second component 70A with the tip portion 53 of the terminal 50 extending inward, the stepped portion 67B, stepped portion 68B and recessed portion 69B provided on the first component 60 engage with the second component 70A. Specifically, as shown in Figures 4 and 5, a stepped portion 67B with a downward-facing stepped surface is formed at the lower end of the outer edge of the front side wall portion 61 of the first component 60. As shown in Figures 3 and 5, a stepped portion 68B with an upward-facing stepped surface is formed in the lower region of the rear side wall portion 61 of the first component 60. As shown in Figure 3, a recessed portion 69B that is recessed toward the front side (towards the internal space of the first component 60) is formed in the upper region of the rear side wall portion 61 of the first component 60. When the first part 60 is assembled to the second part 70B, the stepped portion 67B of the first part 60 engages with the stepped portion 77 of the second part 70B (see Figure 12), the stepped portion 68B of the first part 60 engages with the stepped portion 78 of the second part 70B (see Figure 12), and the locking piece 79 of the second part 70B engages with the outer opening edge 69Ba of the recess 69B of the first part 60 (see Figure 11).

[0031] In order to assemble the first part 60, to which the terminal-equipped wire 30 is attached, onto the second part 70B, first, the first part 60, with the tip 53 of the terminal 50 facing inward, is tilted and moved from below towards the inside of the first part housing 72, and the recess 66 of the first part 60 is engaged (hooked) with the protrusion 75 of the second part 70B. Next, using the engagement point between the recess 66 and the protrusion 75 as a pivot point, the first part 60 is rotated clockwise relative to the second part 70B when viewed from the front in the front-rear direction, and the first part 60 is housed in the first part housing 72. As the first part 60 is rotated, as can be seen from Figure 11, in the process that the connecting wall portion 62 of the first part 60 approaches the plate-shaped portion 71 of the second part 70B, the locking piece 79 of the second part 70B elastically deforms backward so as to be pushed aside by the outer opening edge portion 69Ba of the recess 69B of the first part 60. After the opening edge portion 69Ba overcomes the locking piece 79, the locking piece 79 elastically returns to its original position and engages with the opening edge portion 69Ba. In this way, as the rotation of the first part 60 progresses, the locking piece 79 engages with the opening edge portion 69Ba of the recess 69B, completing the housing of the first part 60 into the first part housing portion 72. As a result, the assembly of the first part 60 with the terminal-equipped wire 30 attached to the second part 70B is completed, and the assembly of the side cover 20B (= first part 60 + second part 70B) is completed.

[0032] When the side cover 20B (= first part 60 + second part 70B) is assembled, as with the side cover 20A, as shown in Figure 7, the protrusion 75 of the second part 70B is fitted into the recess 66 of the first part 60, and the outer surface of the protrusion 75 faces the inner surface of the groove of the recess 66, thereby restricting the relative movement between the first part 60 and the second part 70B. Furthermore, as shown in Figures 7 and 8, the bent portion 54 of the terminal 50 of the terminal-equipped wire 30 is sandwiched between the holding surface 65 of the first part 60 and the holding surface 76 of the second part 70B. More specifically, the holding surface 65 of the first part 60 is in contact with (or positioned close to) the inner surface 54a of the bent portion 54 of the terminal 50, and the holding surface 76 of the second part 70B is in contact with (or positioned close to) the outer surface 54b of the bent portion 54 of the terminal 50. This reduces the displacement of the terminal 50. The tip 53 of the terminal 50 is exposed to the outside so as to protrude inward from the gap between the bent plate portion 64 of the first component 60 and the extended plate portion 74a of the second component 70B. Furthermore, as shown in Figure 12, the downward-facing stepped surface of the stepped portion 67B of the first component 60 engages with the upward-facing stepped surface of the stepped portion 77 of the second component 70B. This restricts the relative downward movement of the first component 60 with respect to the second component 70B. Furthermore, as shown in Figure 12, the upward-facing stepped surface of the stepped portion 68A of the first component 60 engages with the downward-facing stepped surface of the stepped portion 78 of the second component 70B, and the upper edge of the connecting wall portion 62 of the first component 60 engages with the upper wall portion 74 of the second component 70B. This restricts the relative upward movement of the first component 60 with respect to the second component 70B. Furthermore, as shown in Figure 11, the locking piece 79 of the second part 70B engages with the opening edge 69Ba of the recess 69B of the first part 60. This restricts the relative rotation of the first part 60 toward the second part 70B, with the engagement point between the recess 66 and the protrusion 75 as the pivot point.

[0033] Once the assembly of the side cover 20B (= first part 60 + second part 70B) is complete, the side cover 20B with the terminal-equipped wire 30 attached is then assembled to the main body 10 as the selection cover 20Z. Specifically, the plate-shaped portion 71 of the selection cover 20Z with the terminal-equipped wire 30 attached is assembled to the main body 10 so that it slides downward from the top towards the notch 12 of the peripheral wall 11 of the main body 10, and so that the stud bolt 14 protruding upward from the retaining member 13 provided inside the notch 12 is inserted through the through hole 55 provided in the tip 53 of the terminal 50 that extends inward. The above describes the case in which the side cover 20B (60 + 70B) is selected as the selection cover 20Z.

[0034] Next, we will explain the case where a selection cover 20Z is assembled to the notch 12 of the main body 10, which is provided so that the retaining member 13 (stud bolt 14) is located on the rear side of the notch 12. That is, the case where a side cover 20C (60+70C) is selected as the selection cover 20Z so that the tip 53 of the terminal 50 extends backward in order to insert the through hole 55 of the terminal 50 into the stud bolt 14 located on the rear side of the notch 12. As shown in Figure 5, in this case, a first component 60, to which a wire 30 with a terminal is assembled, is assembled to the second component 70C with the tip 53 of the terminal 50 extending backward. When describing the first component 60 below, it will be assumed that the first component 60 is oriented with the tip 53 of the terminal 50 extending backward (as shown in Figure 5).

[0035] Regarding the second component 70C shown in Figure 5, parts that are the same as or equivalent to those of the second component 70A shown in Figure 3 are denoted by the same reference numerals as those shown in Figure 3. The second component 70C shown in Figure 5 has a configuration in which the entire structure of the second component 70A shown in Figure 3 is arranged in the reverse direction in the front-to-back direction. For this reason, the extension plate portion 74a is provided to extend further rearward from the rear edge of the upper wall portion 74, corresponding to the rearward extension of the tip portion 53 of the terminal 50.

[0036] Furthermore, in accordance with the fact that the first component 60 is assembled to the second component 70C with the tip portion 53 of the terminal 50 extending rearward, the stepped portions 67C, 68C, and recesses 69C provided on the first component 60 engage with the second component 70C. Specifically, as shown in Figures 3 and 4, a stepped portion 67C with a downward-facing stepped surface is formed at the lower end of the rear edge of the outer side wall portion 61 of the first component 60. As shown in Figures 3 and 5, a stepped portion 68C with an upward-facing stepped surface is formed in the lower region of the connecting wall portion 62 of the first component 60. As shown in Figure 5, a recess 69C that is recessed toward the rear side (towards the internal space of the first component 60) is formed in the upper region of the connecting wall portion 62 of the first component 60. When the first part 60 is assembled to the second part 70C, the stepped portion 67C of the first part 60 engages with the stepped portion 77 of the second part 70C (see Figure 14), the stepped portion 68C of the first part 60 engages with the stepped portion 78 of the second part 70C (see Figure 14), and the locking piece 79 of the second part 70C engages with the outer opening edge 69Ca of the recess 69C of the first part 60 (see Figure 13).

[0037] In order to assemble the first part 60, to which the terminal-equipped wire 30 is attached, onto the second part 70C, first, the first part 60, with the tip 53 of the terminal 50 facing backward, is tilted from below so as to follow the inclined surface 73a of the second part 70C, and while being guided along the inclined surface 73a, it is moved towards the inside of the first part housing 72, and the recess 66 of the first part 60 is engaged (hooked) with the protrusion 75 of the second part 70C. Next, using the engagement point between the recess 66 and the protrusion 75 as a pivot point, the first part 60 is rotated clockwise relative to the second part 70C when viewed from the front in the front-rear direction, and the first part 60 is housed in the first part housing 72. As the first part 60 is rotated, as can be seen from Figure 13, in the process that the outer side wall portion 61 of the first part 60 approaches the plate-shaped portion 71 of the second part 70C, the locking piece 79 of the second part 70C elastically deforms forward so as to be pushed aside by the outer opening edge portion 69Ca of the recess 69C of the first part 60. After the opening edge portion 69Ca overcomes the locking piece 79, the locking piece 79 elastically returns to its original position and engages with the opening edge portion 69Ca. In this way, as the rotation of the first part 60 progresses, the locking piece 79 engages with the opening edge portion 69Ca of the recess 69C, completing the housing of the first part 60 into the first part housing portion 72. As a result, the assembly of the first part 60 with the terminal-equipped wire 30 attached into the second part 70C is completed, and the assembly of the side cover 20C (= first part 60 + second part 70C) is completed.

[0038] When the side cover 20C (= first part 60 + second part 70C) is assembled, as with the side cover 20A, as shown in Figure 7, the protrusion 75 of the second part 70C is fitted into the recess 66 of the first part 60, and the outer surface of the protrusion 75 faces the inner surface of the groove of the recess 66, thereby restricting the relative movement between the first part 60 and the second part 70C. Furthermore, as shown in Figures 7 and 8, the bent portion 54 of the terminal 50 of the terminal-equipped wire 30 is sandwiched between the holding surface 65 of the first part 60 and the holding surface 76 of the second part 70C. More specifically, the holding surface 65 of the first part 60 is in contact with (or positioned close to) the inner surface 54a of the bent portion 54 of the terminal 50, and the holding surface 76 of the second part 70C is in contact with (or positioned close to) the outer surface 54b of the bent portion 54 of the terminal 50. This reduces the displacement of the terminal 50. The tip 53 of the terminal 50 is exposed to the outside so as to protrude rearward from the gap between the bent plate portion 64 of the first component 60 and the extended plate portion 74a of the second component 70C. Furthermore, as shown in Figure 14, the downward-facing stepped surface of the stepped portion 67C of the first component 60 engages with the upward-facing stepped surface of the stepped portion 77 of the second component 70C. This restricts the relative downward movement of the first component 60 with respect to the second component 70C. Furthermore, as shown in Figure 14, the upward-facing stepped surface of the stepped portion 68C of the first component 60 engages with the downward-facing stepped surface of the stepped portion 78 of the second component 70C, and the upper edge of the outer side wall portion 61 of the first component 60 engages with the upper wall portion 74 of the second component 70C. This restricts the relative upward movement of the first component 60 with respect to the second component 70C. Furthermore, as shown in Figure 13, the locking piece 79 of the second part 70C engages with the opening edge 69Ca of the recess 69C of the first part 60. This restricts the relative rotation of the first part 60 toward the second part 70C, with the engagement point between the recess 66 and the protrusion 75 as the pivot point.

[0039] Once the assembly of the side cover 20C (= first part 60 + second part 70C) is complete, the side cover 20C with the terminal-equipped wire 30 attached is then assembled to the main body 10 as the selectable cover 20Z. Specifically, the plate-shaped portion 71 of the selectable cover 20Z with the terminal-equipped wire 30 attached is assembled to the main body 10 so that it slides downward from the top towards the notch 12 of the peripheral wall 11 of the main body 10, and so that the stud bolt 14 protruding upward from the retaining member 13 provided on the rear side of the notch 12 is inserted through the through hole 55 provided in the tip 53 of the terminal 50 that extends to the rear. The above describes the case in which the side cover 20C (60 + 70C) is selected as the selectable cover 20Z.

[0040] <Effects and Actions> As described above, according to the electrical junction box 1 of this embodiment, the electrical junction box 1 is manufactured using a selectable cover 20Z selected from a plurality of side covers 20A to 20C. The selectable cover 20Z comprises a first component 60 and second components 70A to 70C. The first component 60 is common to all of the plurality of side covers 20A to 20C, while the second components 70A to 70C differ for each of the plurality of side covers 20A to 20C. The electrical junction box 1 is then manufactured by attaching the first component 60, which is mounted on the terminal-equipped wire 30, to the second components 70A to 70C corresponding to the selectable cover 20Z. As a result, since the first component 60 is a common component, the production cost of the selectable cover 20Z can be reduced compared to the case where the entire side cover differs for each selectable cover 20Z. Therefore, the manufacturing method according to this embodiment is superior in terms of production cost for the electrical junction box 1.

[0041] Another effect is that when the first component 60 is assembled to the second components 70A to 70C, the terminal portion 51 of the terminal-equipped wire 30 is sandwiched between the first retaining surface 65 of the first component 60 and the second retaining surface 76 of the second components 70A to 70C. When assembling the terminal 50 to the first component 60, if a sufficiently large clearance is provided between the first component 60 and the terminal 50, the terminal 50 can be easily assembled to the first component 60. Furthermore, if the first component 60 and the second components 70A to 70C are designed such that when the first component 60 is assembled to the second components 70A to 70C, the first retaining surface 65 of the first component 60 contacts (or is positioned in close proximity to) the terminal 50, and the second retaining surface 76 of the second components 70A to 70C also contacts (or is positioned in close proximity to) the terminal 50, then the displacement of the terminal 50 can be reduced when assembling the first component 60 to the second components 70A to 70C. Furthermore, this improves the workability when connecting the terminal portion 51 of the terminal-equipped electric wire 30 to terminals (stud bolts 14) located in the internal space of the electrical connection box 1.

[0042] Furthermore, according to the manufacturing method of the electrical connection box 1 according to this embodiment, one selection cover 20Z is selected from a plurality of side covers 20A to 20C based on the direction in which the terminal portion 51 of the terminal 50 extends from the selection cover 20Z. This makes it possible to extend the terminal portion 51 of the terminal 50 in various directions from the selection cover 20Z while using the first component 60 of the selection cover 20Z, which is a common component.

[0043] Furthermore, according to the manufacturing method of the electrical junction box 1 according to this embodiment, a protrusion 75 on one of the first component 60 and the second components 70A to 70C is fitted into a recess 66 on the other, and the outer surface of the protrusion 75 faces the inner surface of the groove of the recess 66, thereby restricting the relative movement between the first component 60 and the second components 70A to 70C. This interlocking structure allows the first component 60 to be easily assembled onto the second components 70A to 70C, and also effectively suppresses misalignment between the first component 60 and the second components 70A to 70C.

[0044] Furthermore, according to the manufacturing method of the electrical connection box 1 according to this embodiment, the rod-shaped terminal (stud bolt 14) of the main body 10 is inserted through the through hole 55 of the terminal portion 51 of the terminal-equipped wire 30. Since the misalignment of the terminal 50 of the terminal-equipped wire 30 is reduced, the work of inserting the rod-shaped terminal 14 into the through hole 55 can be easily performed.

[0045] <Other forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.

[0046] In the above embodiment, a recessed-concave interlocking structure is formed in which the protrusions 75 provided on the second parts 70A to 70C are fitted into the recesses 66 provided on the first part 60, thereby restricting the relative movement between the first part 60 and the second parts 70A to 70C. Alternatively, a recessed-concave interlocking structure may be formed in which the protrusions provided on the first part 60 are fitted into the recesses provided on the second parts 70A to 70C, thereby restricting the relative movement between the first part 60 and the second parts 70A to 70C.

[0047] Furthermore, in the above embodiment, one of the selectable covers Z is selected from the side covers 20A to 20C based on the direction in which the tip portion 53 of the terminal 50 extends from the selectable cover 20Z. In contrast, one of the selectable covers Z may be selected from the side covers 20A to 20C based on a viewpoint different from the viewpoint of which direction the tip portion 53 of the terminal 50 extends from the selectable cover 20Z.

[0048] Herein, the features of the embodiments of the electrical junction box 1 according to the present invention described above are briefly summarized and listed below in [1] to [5].

[0050] According to the manufacturing method for an electrical junction box with the configuration described in [1] above, the electrical junction box is manufactured using a selectable part that is chosen from a plurality of retaining parts (e.g., a side cover). The selectable part comprises a first part and a second part. The first part is common to all of the plurality of retaining parts, while the second part differs for each of the plurality of retaining parts. The electrical junction box is then manufactured by attaching the first part, which is mounted on a wire with a terminal, to the second part corresponding to the selectable part. As a result, since the first part is a common part, the production cost of the selectable part can be reduced compared to the case where both the first part and the second part differ for each selectable part. Furthermore, when the first part is assembled to the second part, the terminal portion of the wire with a terminal is sandwiched between the first retaining surface of the first part and the second retaining surface of the second part. When assembling the terminal to the first part, if a sufficiently large clearance is provided between the first part and the terminal, the terminal can be easily assembled to the first part. Furthermore, if the first and second parts are designed such that when the first part is assembled to the second part, the first retaining surface of the first part contacts (or is positioned close to) the terminal, and the second retaining surface of the second part also contacts (or is positioned close to) the terminal, then the displacement of the terminal can be reduced when assembling the first part to the second part. By reducing the displacement of the terminal, the workability when connecting the terminal portion of the wire with a terminal to terminals located in the internal space of an electrical junction box is also improved. Therefore, this manufacturing method offers excellent productivity and cost-effectiveness, as well as superior holding performance for wires with terminals.

[0051] [2] In the method for manufacturing the electrical junction box (1) described above [1], The first retaining surface (65) is The terminal portion (51) faces the one surface (54a) of the bent portion (54), The second retaining surface is The other surface (54b) of the bent portion (54) of the terminal portion (51) A method for manufacturing an electrical junction box (1).

[0052] According to the method for manufacturing an electrical junction box described in [2] above, by holding the bent portion of the terminal with the first retaining surface and the second retaining surface, the misalignment of the terminal portion after assembly can be further reduced.

[0053] [3] In the method for manufacturing the electrical junction box (1) described above [1], Based on the direction in which the terminal portion (51) of the terminal-equipped electric wire (30) extends from the selection component (20Z), one of the plurality of holding components (20A to 20C) is selected. A method for manufacturing an electrical junction box (1).

[0054] According to the manufacturing method of the electrical junction box with the configuration described in [3] above, one of the multiple holding parts is selected based on the direction in which the terminal portion of the terminal extends from the selected part. This makes it possible to extend the terminal portion of the terminal in various directions from the selected part while using the first part of the selected part, which is a common part.

[0055] [4] In the method for manufacturing the electrical junction box (1) described above [1], The first part (60) and the second part (70A~70C) are, The first part (60) and the second part (70A-70C) have a protrusion (75) which fits into a recess (66) which fits into the other, and the outer surface of the protrusion (75) faces the inner surface of the groove of the recess (66), thereby restricting the relative movement between the first part (60) and the second part (70A-70C), having a recessed-protrusion-recessed interlocking structure. A method for manufacturing an electrical junction box (1).

[0056] According to the manufacturing method of the electrical junction box with the configuration described in [4] above, a protrusion on one of the first and second parts is fitted into a recess on the other, and the outer surface of the protrusion faces the inner surface of the groove of the recess, thereby restricting relative movement between the first and second parts. This interlocking structure allows the first part to be easily assembled onto the second part, and also effectively suppresses misalignment between the first and second parts.

[0057] [5] In the method for manufacturing the electrical junction box (1) described above [1], The main body (10) has a rod-shaped terminal (14) arranged in the internal space, The terminal portion (51) of the terminal-equipped electric wire (30) has a through hole (55) through which the rod-shaped terminal (14) is inserted. One of the multiple holding parts (20A to 20C) is selected such that the terminal portion (51) extends from the selected part (20Z) toward the rod-shaped terminal (14). A method for manufacturing an electrical junction box (1).
