Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in an assembly as disclosed in Patent Document 1, the assembly may have a structure in which terminals are inserted from the back side of the base plate and assembled on the surface. In such assembly, it is necessary to turn the base plate over, insert the terminals from the back side, and then return the base plate so that its surface faces up. This operation requires time and effort to turn the base plate over when assembling the assembly. For example, when the base plate is large, the time and effort required to turn the base plate over are excessive. Therefore, it is difficult to improve the assembly workability.

[0005] One embodiment is to provide an assembly that can improve the assembly workability.

Hereinafter, when the +X direction and the -X direction are not distinguished, it is simply referred to as the "X direction".

[0017] The Y direction is the direction of the first base sides 2b, 2c facing each other (that is, the direction intersecting the X direction). The +Y direction is the direction of the second base side 2d on the base plate 2 among the Y directions. The -Y direction is the direction of the second base side 2e on the base plate 2 among the Y directions. Hereinafter, when the +X direction and the -X direction are not distinguished, it is simply referred to as the "X direction".

[0018] The Z direction intersects the X and Y directions. The +Z direction is the direction toward the surface 2a of the base plate 2. The -Z direction is the direction toward the back surface (not shown) of the base plate 2. Hereinafter, when not distinguishing between the +Z direction and the -Z direction, it is simply referred to as the "Z direction".

[0019] Hereinafter, the +X direction side may be referred to as "left", the -X direction side as "right", the +Y direction as "front", and the -Y direction as "rear". Also, the +Z direction side may be referred to as "up" and the -Z direction side as "down". However, these expressions are for convenience of explanation and do not limit the mounting posture of the assembly 1.

[0020] <2. Configuration of the Base Plate> The detailed configuration of the base plate 2 will be described. The base plate 2 is formed in a substantially rectangular shape by, for example, the first base sides 2b, 2c and the second base sides 2d, 2e.

The cover mounting portion 22 protrudes upward from the surface 3a of the intermediate plate 3. The cover mounting portion 22 is formed in a substantially rectangular shape in plan view so that it can be housed inside the cover 9, which will be described later.

[0025] <4. Configuration of the terminal storage section> As shown in Figures 4 to 6, the terminal storage section 4 is provided separately from the base plate 2. The terminal storage section 4 is integrally provided on the bottom of the cover mounting section 22 (i.e., the intermediate plate 3) inside the cover mounting section 22. In this embodiment, an example in which the terminal storage section 4 is integrally provided on the intermediate plate 3 is described, but it is not limited to this. As another example, the terminal storage section 4 may be configured to be assembled to the intermediate plate 3.

[0026] The terminal storage section 4 is integrally mounted on the intermediate plate 3 and protrudes vertically from the intermediate plate 3. The terminal storage section 4 has a protruding portion 24 and a storage hole 25. The protruding portion 24 protrudes downward from the intermediate plate 3 toward the base plate 2. The protruding portion is formed so that it can be inserted (placed) into the receiving portion 12 from the surface 2a side of the base plate 2.

[0027] The storage hole 25 includes, for example, a first storage hole 25A and a second storage hole 25B. The first storage hole 25A is provided on the left side of the terminal storage section 4. The first storage hole 25A is vertically through. The first terminal 5A, described later, is stored in the first storage hole 25A by being inserted from the lower end side (i.e., the side with the protruding portion 24) of the terminal storage section 4. The second storage hole 25B is provided on the right side of the terminal storage section 4. The second storage hole 25B is vertically through.

[0028] <5. Terminal Configuration> The detailed configuration of terminal 5 will be explained below. Terminal 5 comprises, for example, a first terminal 5A and a second terminal 5B. The first terminal 5A is housed in the first housing hole 25A of the terminal housing 4 from the lower end side of the terminal housing 4. The second terminal 5B is housed in the second housing hole 25B of the terminal housing 4 from the lower end side of the terminal housing 4. The first terminal 5A and the second terminal 5B are assembled to the base plate 2 from the surface 2a side of the base plate 2 by inserting the protruding portion 24 of the terminal housing 4 into the receiving portion 12 from the surface 2a side of the base plate 2. The first terminal 5A and the second terminal 5B are, for example, the same terminal.

[0029] The first terminal 5A is located to the left of the second terminal 5B. One end of the first electric wire 6A, which will be described later, is connected to the lower end of the first terminal 5A. The first terminal 5A has a locking hole 27 located approximately in the center in the vertical direction. The second terminal 5B is located to the right of the first terminal 5A. One end of the second electric wire 6B, which will be described later, is connected to the lower end of the second terminal 5B. The second terminal 5B has a locking hole 28 located approximately in the center in the vertical direction. The reason for providing the locking hole 27 on the first terminal 5A and the locking hole 28 on the second terminal 5B will be explained in detail later. In this embodiment, the first terminal 5A and the second terminal 5B are used as examples of terminals 5, but the number of terminals 5 can be arbitrarily selected.

[0030] <6. Wire configuration> The detailed configuration of wire 6 will be explained below. As shown in Figures 2 and 3, the electric wire 6 comprises, for example, a first electric wire 6A, a second electric wire 6B, and a third electric wire 6C. One end of the first electric wire 6A is connected to the first terminal 5A, and it is routed through the opening 19 from the surface 2a side of the base plate 2 into the routing groove 13. The other end of the first electric wire 6A is connected to the first connector 7A (described later) via one end 13a of the routing groove 13.

[0031] One end of the second wire 6B is connected to the second terminal 5B, and it is routed through the opening 19 from the surface 2a side of the base plate 2 into the routing groove 13. The other end of the second wire 6B is connected to the second connector 7B (described later) via the other end 13b of the routing groove 13. The third wire 6C is routed from the surface 2a side of the base plate 2 into the routing groove 13. One end of the third wire 6C is connected to the first connector 7A (described later) via one end 13a of the routing groove 13. The other end of the third wire 6C is connected to the second connector 7B (described later) via the other end 13b of the routing groove 13.

[0032] <7. Connector Configuration> The detailed configuration of connector 7 will be described below. The connector 7 comprises, for example, a first connector 7A and a second connector 7B. The other end of the first wire 6A and one end of the third wire 6C are connected to the first connector 7A. The first connector 7A is positioned on the first connector mounting portion 14 from the surface 2a side of the base plate 2. The other end of the second wire 6B and the other end of the third wire 6C are connected to the second connector 7B. The second connector 7B is positioned on the second connector mounting portion 15 from the surface 2a side of the base plate 2.

[0033] <8. Configuration of the terminal holding section> The detailed configuration of the terminal holding section 8 will now be described. As shown in Figures 5 and 6, the terminal holding portion 8 includes, for example, a first holding piece 41 and a second holding piece 42. The first holding piece 41 includes, for example, a pair of first projections 41A and a pair of second projections 41B. The pair of first projections 41A and the pair of second projections 41B are provided in the terminal housing portion 4.

[0034] The pair of first projections 41A protrude from the upper left end of the terminal housing section 4, for example, so as to face each other in the front-rear direction. The pair of first projections 41A can contact the tip of the first terminal 5A housed in the first housing hole 25A of the terminal housing section 4. The pair of second projections 41B protrude from the upper right end of the terminal housing section 4, for example, so as to face each other in the front-rear direction. The pair of second projections 41B can contact the tip of the second terminal 5B housed in the second housing hole 25B of the terminal housing section 4.

[0035] The second retaining piece 42 comprises, for example, a first locking piece 42A and a second locking piece 42B. The first locking piece 42A and the second locking piece 42B are provided in the terminal housing section 4. The first locking piece 42A protrudes from the wall surface of the first housing hole 25A toward the first terminal 5A. The first locking piece 42A locks into the locking hole 27 (see also Figure 4) of the first terminal 5A housed in the first housing hole 25A of the terminal housing section 4. By locking into the locking hole 27 of the first terminal 5A, the first locking piece 42A can restrict (prevent) the first terminal 5A from coming out of the first housing hole 25A toward the base end side (i.e., toward the first electric wire 6A side).

[0036] The second locking piece 42B protrudes from the wall surface of the second storage hole 25B toward the second terminal 5B. The second locking piece 42B locks into the locking hole 28 (see also Figure 4) of the second terminal 5B which is housed in the second storage hole 25B of the terminal storage section 4. By locking into the locking hole 28 of the second terminal 5B, the second locking piece 42B can prevent the second terminal 5B from coming out of the second storage hole 25B toward the base end side (i.e., toward the first electric wire 6A side).

[0037] The first terminal 5A has a pair of first projections 41A that contact its tip and a first locking piece 42A that locks into the locking hole 27. The first terminal 5A is held by the pair of first projections 41A and first locking pieces 42A when it is housed in the first storage hole 25A of the terminal storage section 4. The second terminal 5B has a pair of second projections 41B that contact its tip and a second locking piece 42B that locks into the locking hole 28. The second terminal 5B is held by the pair of second projections 41B and second locking pieces 42B when it is housed in the second storage hole 25B of the terminal storage section 4.

[0038] <9. Cover composition> This section describes the detailed structure of cover 9. As shown in Figures 1 and 6, the cover 9 is assembled to the intermediate plate 3 from the surface 3a side to the outside of the cover mounting portion 22 (see Figure 2). The cover 9 is formed in a substantially rectangular shape in plan view, for example. Inside the cover 9, a first mating terminal 51 and a second mating terminal 52 are provided. The first mating terminal 51 and the second mating terminal 52 are connected to each other by a connecting member 53, for example. The first mating terminal 51 is provided so as to be able to contact the first terminal 5A when the cover 9 is assembled to the cover mounting portion 22. The second mating terminal 52 is provided so as to be able to contact the second terminal 5B when the cover 9 is assembled to the cover mounting portion 22.

[0039] <10. Assembly methods for the assembly> A representative example of assembling assembly 1 is explained with reference to Figures 1 to 7. Note that the assembly procedure can be selected arbitrarily. As shown in Figures 4 and 7, first, the first terminal 5A is placed in the first storage hole 25A (see Figure 6) from the protruding portion 24 side of the terminal storage section 4 as indicated by arrow A. One end of the first electric wire 6A is pulled upward from the receiving section 12. Next, the second terminal 5B is placed in the second storage hole 25B (see Figure 6) from the protruding portion 24 side of the terminal storage section 4 as indicated by arrow B. One end of the second electric wire 6B is pulled upward from the receiving section 12.

[0040] As shown in Figures 5 and 6, the first terminal 5A housed in the first housing hole 25A is held in the first housing hole 25A by a pair of first projections 41A and first locking pieces 42A in the terminal holding portion 8. The second terminal 5B housed in the second housing hole 25B is held in the second housing hole 25B by a pair of second projections 41B and second locking pieces 42B in the terminal holding portion 8.

[0041] As shown in Figures 6 and 7, the intermediate plate 3 is assembled to the base plate 2 from the surface 2a side as indicated by arrow C. In this state, the protruding portion 24 of the terminal housing portion 4 is inserted into the receiving portion 12 from the surface 2a side of the base plate 2 as indicated by arrow D.

[0042] As shown in Figure 3, the first connector 7A is placed on the first connector mounting portion 14 from the surface 2a side of the base plate 2. The second connector 7B is placed on the second connector mounting portion 15 from the surface 2a side of the base plate 2. The first wire 6A, the second wire 6B, and the third wire 6C are routed into the routing groove 13 from the surface 2a side of the base plate 2.

[0043] As shown in Figures 1 and 6, the cover 9 is assembled to the intermediate plate 3 from the surface 3a side on the outside of the cover mounting portion 22 (see Figure 2). In this state, the first mating terminal 51 contacts the first terminal 5A. The second mating terminal 52 contacts the second terminal 5B. The first mating terminal 51 and the second mating terminal 52 are connected to each other by a connecting member 53. By bringing the first mating terminal 51 and the second mating terminal 52 into contact with the first terminal 5A and the second terminal 5B, the first terminal 5A and the second terminal 5B are connected (short-circuited), and it is detected that the cover 9 is securely closed.

[0044] As shown in Figures 1, 3, and 7, the intermediate plate 3, terminal housing 4, first connector 7A, and second connector 7B are assembled to the base plate 2 from the surface 2a side. The first wire 6A, second wire 6B, and third wire 6C are also assembled to the base plate 2 from the surface 2a side. Furthermore, the cover 9 is assembled to the base plate 2 from the surface 2a side. This assembly process completes the assembly of the assembly body 1. With this configuration, when assembling the assembly body 1, components such as the terminal housing 4 can be assembled from the surface 2a side of the base plate 2 without inverting the base plate 2.

[0045] <11. Mechanism and Effects> In the assembly 1 of this embodiment, as shown in Figures 2 and 6, the terminal housing section 4 is separate from the base plate 2 and is provided on the intermediate plate 3. The terminal housing section 4 houses the first terminal 5A and the second terminal 5B. In this state, the intermediate plate 3 is assembled to the base plate 2 from the surface 2a side. With this configuration, the first terminal 5A and the second terminal 5B can be assembled to the base plate 2 from the surface 2a side. Therefore, when assembling the first terminal 5A and the second terminal 5B to the base plate 2, the effort of turning the base plate 2 over is eliminated, improving the assembly workability of the assembly 1.

[0046] In the assembly 1 of this embodiment, as shown in Figure 2, the terminal storage section 4 is integrally provided with the intermediate plate 3. This configuration eliminates the need to assemble the terminal storage section 4 to the intermediate plate 3, further improving the assembly efficiency of the assembly 1.

[0047] In the assembly 1 of this embodiment, as shown in Figure 6, the protruding portion 24 of the terminal storage section 4 is inserted into the receiving section 12 from the surface 2a side of the base plate 2. With this configuration, the protruding height of the terminal storage section 4 that protrudes upward from the base plate 2 can be appropriately set. Therefore, the assembly 1 can be made compact. Furthermore, by providing the protruding portion 24 of the terminal storage section 4, sufficient height of the terminal storage section 4 can be secured. With this configuration, the first terminal 5A and the second terminal 5B can be appropriately stored in the terminal storage section 4.

[0048] In the assembly 1 of this embodiment, as shown in Figure 3, the first wire 6A connected to the first terminal 5A is routed to the surface 2a of the base plate 2. The second wire 6B connected to the second terminal 5B is also routed to the surface 2a of the base plate 2. Furthermore, the third wire 6C connected to the first connector 7A and the second connector 7B is routed to the surface 2a of the base plate 2. In addition, the first connector 7A connected to the first wire 6A is assembled from the surface 2a side of the base plate 2. The second connector 7B connected to the second wire 6B is also assembled from the surface 2a side of the base plate 2.

[0049] With this configuration, the first terminal 5A and the second terminal 5B (both, see Figure 6) housed in the terminal storage section 4 can be assembled from the surface 2a side of the base plate 2, in the same way as the first wire 6A, the second wire 6B, the third wire 6C, the first connector 7A, and the second connector 7B. Therefore, the effort of turning the base plate 2 over when assembling the assembly 1 can be eliminated, improving the ease of assembly of the assembly 1.

[0050] According to the assembly 1 of this embodiment, as shown in Figures 5 and 6, the terminal housing section 4 is assembled to the base plate 2 from the surface 2a side together with the intermediate plate 3 when the first terminal 5A and the second terminal 5B are housed in it. With this configuration, when assembling the terminal housing section 4 to the base plate 2, it is conceivable that the first terminal 5A may move within the first housing hole 25A of the terminal housing section 4 or come out of the first housing hole 25A. Similarly, it is conceivable that the second terminal 5B may move within the second housing hole 25B of the terminal housing section 4 or come out of the second housing hole 25B.

[0051] Therefore, the terminal storage section 4 is equipped with a terminal holding section 8, which holds the first terminal 5A stored in the first storage hole 25A. The terminal holding section 8 also holds the second terminal 5B stored in the second storage hole 25B. With this configuration, when assembling the terminal storage section 4 to the base plate 2, the first terminal 5A and the second terminal 5B can be reliably held in the state where they are stored in the terminal storage section 4.

[0052] Specifically, the terminal holding portion 8 includes a first holding piece 41 and a second holding piece 42 in the terminal storage portion 4. The first holding piece 41 has a pair of first projections 41A that can contact the tip of the first terminal 5A. The second holding piece 42 has a first locking piece 42A that can lock into the locking hole 27 of the first terminal 5A, thereby preventing the first terminal 5A from coming out of the locking hole 27 toward the base end. Furthermore, the first holding piece 41 has a pair of second projections 41B that can contact the tip of the second terminal 5B. The second holding piece 42 has a second locking piece 42B that can lock into the locking hole 28 of the second terminal 5B, thereby preventing the second terminal 5B from coming out of the locking hole 28 toward the base end.

[0053] With this configuration, the first terminal 5A can be securely held by the terminal holding part 8 in the state where it is housed in the first housing hole 25A of the terminal housing part 4. Similarly, the second terminal 5B can be securely held by the terminal holding part 8 in the state where it is housed in the second housing hole 25B of the terminal housing part 4.

[0054] Several embodiments and modifications have been described above. However, the embodiments and modifications are not limited to the examples described above. For example, multiple embodiments may be implemented in combination with each other. [Explanation of Symbols]
