Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in an assembly such as that 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 items. 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.

Means for Solving the Problems

[0006] One embodiment of the assembly comprises a base plate on which at least one of an electronic component and a busbar can be mounted on its surface side, a terminal housing section that can be assembled to the base plate from the surface side, terminals housed inside the terminal housing section, and a holding section that holds the terminal housing section to the base plate. [Effects of the Invention]

[0007] According to one embodiment, assembly workability can be improved. [Brief explanation of the drawing]

The base plate 2 is formed in a substantially rectangular shape in plan view by opposing first base sides 2b, 2c and opposing second base sides 2d, 2e. The opposing first base sides 2b, 2c are formed to be longer than the opposing second base sides 2d, 2e.

[0013] The terminal housing section 3 can be assembled to the base plate 2 from the surface 2a side. The terminal housing section 3 is open in the direction of the surface 2a (+Z direction) such that the tip of the terminal 4 is exposed in the +Z direction. The terminal housing section 3 is assembled by being inserted into the base plate 2 from the surface 2a side. The terminal 4 is housed inside the terminal housing section 3. The terminal 4 is exposed in the +Z direction from the terminal housing section 3 so that it can be connected to the mating terminal. The terminal 4 extends from the connected wire 5 through the inside of the terminal housing section 3 in the +Z direction. The wire 5 is connected to the terminal 4 and routed on the surface 2a of the base plate 2. The wire 5 is routed on the second base side 2d of the base plate 2 relative to the terminal housing section 3 (i.e., terminal 4).

[0014] The connector 6 can be assembled to the base plate 2 from the surface 2a side of the base plate 2. The connector 6 is connected to the electric wire 5 and assembled to the base plate 2 from the surface 2a side of the base plate 2. The retaining part 7 holds the terminal storage part 3 to the base plate 2. The terminal retaining part 8 holds the terminal 4 stored in the terminal storage part 3.

[0015] In this disclosure, the X direction, +X direction, -X direction, +Y direction, -Y direction, Z direction, +Z direction, and -Z direction are defined as follows:

[0016] The X direction is the direction along the opposing second base edges 2d and 2e on the base plate 2. The +X direction is the direction of the first base edge 2b on the base plate 2 within the X direction. The -X direction is the direction of the first base edge 2c on the base plate 2. Hereafter, if the +X direction and the -X direction are not distinguished, they will simply be referred to as the "X direction".

[0017] The Y direction is the direction of the opposing first base sides 2b, 2c (i.e., 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 not distinguishing between the +X direction and the -X direction, it is simply referred to as the "X direction".

[0018] The Z direction is the direction intersecting the X direction and the Y direction. The +Z direction is the direction on the surface 2a side of the base plate 2. The -Z direction is the direction on the back side (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 may be referred to as "right", the +Y direction may be referred to as "front", and the -Y direction may be referred to as "rear". Also, the +Z direction side may be referred to as "up" and the -Z direction side may be referred to 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 base plate 2 has mounting holes 11 penetrating in the vertical direction provided at the four corners (only three corners are shown). The base plate 2 is assembled to a connection box body (both not shown) by bolts inserted into the mounting holes 11. The base plate 2 has a receiving portion 12, a cable routing groove 13, a first connector mounting portion 14, and a second connector mounting portion 15.

[0021] As shown in Figures 2, 4, and 5, the receiving portion 12 has an opening 18 on the surface 2a of the base plate 2 (see also Figure 1). The receiving portion 12 is open to the surface 2a of the base plate 2 via the opening 18. The receiving portion 12 is open in the vertical direction from the surface 2a of the base plate 2 toward the back surface (not shown). The receiving portion 12 is formed so that the protruding portion 24 (described later) of the terminal housing portion 3 can be received from the surface 2a side of the base plate 2 via the opening 18. The receiving portion 12 is in communication with the cable routing groove 13 (described later) via an opening 19.

[0022] The opening 18 is provided on the surface 2a of the base plate 2. The opening 18 is formed in a substantially rectangular shape by opposing first opening sides 18a, 18a and opposing second opening sides 18b, 18b. The opposing first opening sides 18a, 18a extend along the left-right direction. The opposing second opening sides 18b, 18b extend along the front-back direction. The opposing first opening sides 18a, 18a are formed to be longer than the opposing second opening sides 18b, 18b. The opening 18 is provided with a restricting portion 31 (described later) of the retaining portion 7.

[0023] As shown in Figures 1 and 3, the cable routing groove 13 is provided so as to open into the surface 2a of the base plate 2. The cable routing groove 13 extends from the opening 19 communicating with the receiving portion 12 to the first connector mounting portion 14. The cable routing groove 13 also extends from the opening 19 to the second connector mounting portion 15 (see Figure 2).

[0024] The first connector mounting portion 14 is connected to one end 13a of the cable routing groove 13. The first connector 6A, which will be described later, is positioned on the first connector mounting portion 14. The second connector mounting portion 15 is connected to the other end 13b of the cable routing groove 13. The second connector 6B, which will be described later, is positioned on the second connector mounting portion 15.

[0025] <3. Configuration of the terminal storage section> The detailed configuration of the terminal housing section 3 will now be described. As shown in Figures 2, 4, and 5, the terminal storage section 3 is constructed separately from the base plate 2. The terminal storage section 3 comprises, for example, opposing first walls 3a, 3a and opposing second walls 3b, 3b. The terminal storage section 3 is formed as a substantially rectangular shape extending vertically by, for example, opposing first walls 3a, 3a and opposing second walls 3b, 3b. The first walls 3a, 3a extend to the left and right sides. The second walls 3b, 3b extend to the front and rear sides. A pair of guide portions 21, 21 are provided on the left and right sides of the first walls 3a, 3a at intervals. The guide portions 21, 21 extend vertically while protruding from the first walls 3a, 3a in the front and rear directions. The terminal storage section 3 has a protruding portion 24 and a storage hole 25.

[0026] The protruding portion 24 is formed at the lower end of the terminal storage portion 3. The protruding portion 24 is formed to be insertable into the receiving portion 12 from the surface 2a side of the base plate 2. Specifically, the protruding portion 24 is inserted into the receiving portion 12, for example, with the guide portions 21, 21 of the opposing first walls 3a, 3a in contact with the first opening edges 18a, 18a of the opening 18, and the opposing second walls 3b, 3b in contact with the second opening edges 18b, 18b of the opening 18. By bringing the guide portions 21, 21 of the opposing first walls 3a, 3a into contact with the first opening edges 18a, 18a, the protruding portion 24 can be smoothly inserted into the receiving portion 12.

[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 3. The first storage hole 25A penetrates vertically along the opposing first walls 3a, 3a and the opposing second walls 3b, 3b. The first terminal 4A, 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 3. The second storage hole 25B is provided on the right side of the terminal storage section 3. The second storage hole 25B penetrates vertically along the opposing first walls 3a, 3a and the opposing second walls 3b, 3b. The second terminal 4B, described later, is stored in the second storage hole 25B by being inserted from the lower end side (i.e., the side with the protruding portion 24) of the terminal storage section 3.

[0028] The terminal storage section 3 is provided with the protruding portions 32 and 32 of the holding section 7, which will be described later, and the first holding piece 41 and second holding piece 42 of the terminal holding section 8, which will be described later.

[0029] <4. Terminal Configuration> The detailed configuration of terminal 4 will be described below. As shown in Figures 4 to 6, the terminal 4 comprises, for example, a first terminal 4A and a second terminal 4B. The first terminal 4A is housed in the first housing hole 25A of the terminal housing 3 from the lower end side of the terminal housing 3. The second terminal 4B is housed in the second housing hole 25B of the terminal housing 3 from the lower end side of the terminal housing 3. The first terminal 4A and the second terminal 4B 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 3 into the receiving portion 12 from the surface 2a side of the base plate 2. The first terminal 4A and the second terminal 4B are, for example, the same terminal.

[0030] The first terminal 4A is located to the left of the second terminal 4B. One end of the first electric wire 5A, which will be described later, is connected to the lower end of the first terminal 4A. The first terminal 4A has a locking hole 27 approximately in the center in the vertical direction. The second terminal 4B is located to the right of the first terminal 4A. One end of the second electric wire 5B, which will be described later, is connected to the lower end of the second terminal 4B. The second terminal 4B has a locking hole 28 approximately in the center in the vertical direction. The reason for providing the locking hole 27 on the first terminal 4A and the locking hole 28 on the second terminal 4B will be explained in detail later.

[0031] The first terminal 4A and the second terminal 4B are positioned to be in contact with a first mating terminal and a second mating terminal (not shown) when assembled to the base plate 2 together with the terminal housing 3. The first mating terminal and the second mating terminal (not shown) are attached to a cover (not shown) when connected to each other. The first mating terminal and the second mating terminal come into contact with the first terminal 4A and the second terminal 4B when the terminal housing 3 is covered with the cover.

[0032] With this configuration, by bringing the first and second connection terminals into contact with the first terminal 4A and the second terminal 4B, it is possible to detect that the cover has been securely closed by connecting (short-circuiting) the first terminal 4A and the second terminal 4B. In this embodiment, the first terminal 4A and the second terminal 4B are used as examples of terminals 4, but the number of terminals 4 can be arbitrarily selected.

[0033] <5. Wire configuration> The detailed configuration of wire 5 will be explained below. As shown in Figures 2, 3, and 6, the electric wire 5 comprises, for example, a first electric wire 5A, a second electric wire 5B, and a third electric wire 5C. One end of the first electric wire 5A is connected to the first terminal 4A and 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 5A is connected to the first connector 6A (described later) via one end 13a of the routing groove 13.

[0034] The second wire 5B has one end connected to the second terminal 4B and 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 5B is connected to the second connector 6B (described later) via the other end 13b of the routing groove 13. The third wire 5C is routed through the routing groove 13 from the surface 2a side of the base plate 2. One end of the third wire 5C is connected to the first connector 6A (described later) via one end 13a of the routing groove 13. The other end of the third wire 5C is connected to the second connector 6B (described later) via the other end 13b of the routing groove 13.

[0035] <6. Connector Configuration> The detailed configuration of connector 6 will be described below. As shown in Figures 2 and 3, the connector 6 comprises, for example, a first connector 6A and a second connector 6B. The other end of the first wire 5A is connected to the first connector 6A, and one end of the third wire 5C is connected to the first connector 6A. The first connector 6A 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 5B is connected to the second connector 6B, and the other end of the third wire 5C is connected to the second connector 6B. The second connector 6B is positioned on the second connector mounting portion 15 from the surface 2a side of the base plate 2.

[0036] <7. Configuration of the holding part 7> The detailed configuration of the holding part 7 will now be described. As shown in Figures 2, 4, and 5, the holding portion 7 includes, for example, a restricting portion 31, an overhanging portion 32, a locking portion 33, and a support portion 34. The restricting portion 31 is formed by the periphery of the opening 18 of the receiving portion 12. That is, the restricting portion 31 is provided on the receiving portion 12. The restricting portion 31 is formed in a substantially rectangular shape along the opening 18.

[0037] The protruding portion 32 comprises, for example, a first protruding portion 32A and a second protruding portion 32B. The first protruding portion 32A and the second protruding portion 32B are provided in the terminal storage portion 3. The first protruding portion 32A protrudes forward from above the projection 24 along the surface 2a of the base plate 2 on the front first wall 3a of the opposing first walls 3a, 3a. The second protruding portion 32B protrudes rearward from above the projection 24 along the surface 2a of the base plate 2 on the rear first wall 3a of the opposing first walls 3a, 3a. That is, the first protruding portion 32A and the second protruding portion 32B are provided so as to be able to contact the surface of the regulating portion 31 when the projection 24 of the terminal storage portion 3 is inserted into the receiving portion 12.

[0038] The support portion 34 is provided in the terminal storage portion 3. The support portion 34 has an upper end 34a integrally provided on the upper end side of the left second wall 3b (one of the opposing second walls 3b, 3b). The support portion 34 extends downward from the upper end 34a. The support portion 34 is elastically deformable in the left-right direction with the upper end 34a as a fulcrum. When the support portion 34 is not elastically deformed, for example, it is positioned flush with the left second wall 3b.

[0039] The locking portion 33 comprises, for example, a first locking portion 33A and a second locking portion 33B. The first locking portion 33A and the second locking portion 33B are provided on the protruding portion 24 in the terminal housing portion 3. The first locking portion 33A is provided, for example, on the tip 34b of the support portion 34. That is, the first locking portion 33A is supported, for example, on the left second wall 3b of the protruding portion 24 via the support portion 34.

[0040] The first locking portion 33A protrudes to the left from the left second wall 3b, for example, when the support portion 34 is not elastically deformed. The first locking portion 33A is positioned flush with the left second wall 3b when the support portion 34 is elastically deformed. The second locking portion 33B is provided on the right second wall 3b of the opposing second walls 3b, 3b in the protruding portion 24. The second locking portion 33B protrudes to the right from the right second wall 3b, for example.

[0041] The first locking portion 33A and the second locking portion 33B can be inserted into the receiving portion 12 through the opening 18 together with the protruding portion 24 by, for example, elastically deforming the support portion 34 to position the first locking portion 33A flush with the left second wall 3b. When the first locking portion 33A and the second locking portion 33B are inserted into the receiving portion 12 together with the protruding portion 24, the support portion 34 returns to its elastically deformed state. As the support portion 34 returns to its original state, the first locking portion 33A protrudes to the left from the left second wall 3b. As the first locking portion 33A protrudes, the first locking portion 33A and the second locking portion 33B lock onto the back surface of the restricting portion 31 when the protruding portion 24 is inserted into the receiving portion 12.

[0042] Here, the first protruding portion 32A and the second protruding portion 32B are in contact with the surface of the restricting portion 31 when the protruding portion 24 is inserted into the receiving portion 12. Therefore, when the protruding portion 24 is inserted into the receiving portion 12, the holding portion 7 can hold the restricting portion 31 by sandwiching it from above and below with the first protruding portion 32A and the second protruding portion 32B and the first locking portion 33A and the second locking portion 33B. With this configuration, when the protruding portion 24 is inserted into the receiving portion 12, the terminal storage portion 3 can be held on the surface 2a of the base plate 2 by the holding portion 7.

[0043] In this embodiment, an example is described in which only the first protruding portion 32A is provided on the elastically deformable support portion 34, but the embodiment is not limited to this. As another example, for example, the second locking portion 33B may also be provided on the elastically deformable support portion in the same way as the first protruding portion 32A.

[0044] <8. Configuration of the terminal holding section> The detailed configuration of the terminal holding section 8 will now be described. As shown in Figures 4 and 5, 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 3.

[0045] The pair of first projections 41A protrude from the upper left ends of opposing first walls 3a, 3a, facing each other. The pair of first projections 41A can contact the tip of the first terminal 4A housed in the first housing hole 25A of the terminal housing section 3. The pair of second projections 41B protrude from the upper right ends of opposing first walls 3a, 3a, facing each other. The pair of second projections 41B can contact the tip of the second terminal 4B housed in the second housing hole 25B of the terminal housing section 3.

[0046] 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 3. The first locking piece 42A protrudes from the wall surface of the first housing hole 25A toward the first terminal 4A. The first locking piece 42A locks into the locking hole 27 (see also Figure 6) of the first terminal 4A housed in the first housing hole 25A of the terminal housing section 3. By locking into the locking hole 27 of the first terminal 4A, the first locking piece 42A can restrict (prevent) the first terminal 4A from coming out of the first housing hole 25A toward the base end side (i.e., toward the first electric wire 5A side).

[0047] The second locking piece 42B protrudes from the wall surface of the second storage hole 25B toward the second terminal 4B. The second locking piece 42B locks into the locking hole 28 (see also Figure 6) of the second terminal 4B which is housed in the second storage hole 25B of the terminal storage section 3. By locking into the locking hole 28 of the second terminal 4B, the second locking piece 42B can prevent the second terminal 4B from coming out of the second storage hole 25B toward the base end side (i.e., toward the first electric wire 5A side).

[0048] The first terminal 4A has a pair of first projections 41A that contact its tip. The first locking piece 42A is locked into the locking hole 27. The first terminal 4A is held by the pair of first projections 41A and first locking piece 42A when it is housed in the first housing hole 25A of the terminal housing 3. The second terminal 4B has a pair of second projections 41B that contact its tip. The second locking piece 42B is locked into the locking hole 28. The second terminal 4B is held by the pair of second projections 41B and second locking piece 42B when it is housed in the second housing hole 25B of the terminal housing 3.

[0049] <9. Assembly methods for the assembly> A representative example of assembling assembly 1 will be explained based on Figures 2 and 4 through 7. Note that the assembly procedure can be selected arbitrarily. As shown in Figure 6, first, the first terminal 4A is placed in the first storage hole 25A (see Figure 5) from the protruding portion 24 side of the terminal storage section 3 as indicated by arrow A. Then, the second terminal 4B is placed in the second storage hole 25B (see Figure 5) from the protruding portion 24 side of the terminal storage section 3 as indicated by arrow B.

[0050] As shown in Figures 4 and 5, the first terminal 4A 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 4B 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.

[0051] As shown in Figure 2, the protruding portion 24 of the terminal storage portion 3 is inserted into the receiving portion 12 from the surface 2a side of the base plate 2 as indicated by arrow C. The first connector 6A is positioned on the first connector mounting portion 14 from the surface 2a side of the base plate 2 as indicated by arrow D. The second connector 6B is positioned on the second connector mounting portion 15 from the surface 2a side of the base plate 2 as indicated by arrow E. The first wire 5A, the second wire 5B, and the third wire 5C are routed into the routing groove 13 from the surface 2a side of the base plate 2 as indicated by arrow F.

[0052] As shown in Figures 4 and 5, with the protruding portion 24 inserted into the receiving portion 12, the first locking portion 33A and the second locking portion 33B and the first protruding portion 32A and the second protruding portion 32B of the holding portion 7 hold the restricting portion 31 in a state where it is sandwiched from above and below. With this configuration, the terminal storage portion 3 is held by the holding portion 7 in a state where it is assembled to the base plate 2.

[0053] As shown in Figure 7, the terminal housing section 3, the first connector 6A, and the second connector 6B are assembled to the base plate 2 from the surface 2a side. In addition, the first wire 5A, the second wire 5B, and the third wire 5C are assembled to the base plate 2 from the surface 2a side. This assembly process completes the assembly of the assembly body 1. In other words, when assembling the assembly body 1, components such as the terminal housing section 3 can be assembled from the surface 2a side of the base plate 2 without inverting the base plate 2.

[0054] <10. Mechanism and Effects> In the assembly 1 of this embodiment, as shown in Figures 2 and 5, the base plate 2 and the terminal storage section 3 are separate components. The first terminal 4A and the second terminal 4B are housed inside the terminal storage section 3. With this configuration, the terminal storage section 3, which houses the first terminal 4A and the second terminal 4B, can be assembled from the surface 2a side of the base plate 2. Furthermore, the assembled terminal storage section 3 can be held on the base plate 2 by the holding section 7. Therefore, when assembling the first terminal 4A and the second terminal 4B to the base plate 2, the effort of turning the base plate 2 over is eliminated, improving the assembly workability of the assembly 1.

[0055] In the assembly 1 of this embodiment, the first wire 5A connected to the first terminal 4A is routed to the surface 2a of the base plate 2. The second wire 5B connected to the second terminal 4B is also routed to the surface 2a of the base plate 2. Furthermore, the third wire 5C connected to the first connector 6A and the second connector 6B is routed to the surface 2a of the base plate 2. In addition, the first connector 6A connected to the first wire 5A is assembled from the surface 2a side of the base plate 2. The second connector 6B connected to the second wire 5B is also assembled from the surface 2a side of the base plate 2.

[0056] With this configuration, the first terminal 4A and the second terminal 4B housed in the terminal storage section 3 can be assembled from the surface 2a side of the base plate 2, in the same way as the first wire 5A, the second wire 5B, the third wire 5C, the first connector 6A, and the second connector 6B. Therefore, the effort of turning the base plate 2 over when assembling the assembly 1 is eliminated, improving the ease of assembly of the assembly 1.

[0057] According to the assembly 1 of this embodiment, as shown in Figures 2, 4, and 5, the holding portion 7 includes a restricting portion 31 on the receiving portion 12 of the base plate 2, and an overhanging portion 32 and a locking portion 33 on the terminal storage portion 3. Furthermore, the overhanging portion 32 is made contact with the surface of the restricting portion 31. In addition, the locking portion 33 is made lockable to the back surface of the restricting portion 31. With this configuration, when the terminal storage portion 3 is received in the receiving portion 12, the overhanging portion 32 can be made contact with the surface of the restricting portion 31, and the locking portion 33 can be locked to the back surface of the restricting portion 31. Therefore, the terminal storage portion 3 can be securely held in place on the base plate 2 by the holding portion 7.

[0058] According to the assembly 1 of this embodiment, as shown in Figures 4 and 5, the first protruding portion 32A of the holding portion 7 is provided on the front first wall 3a of the terminal storage portion 3. The second protruding portion 32B of the holding portion 7 is provided on the rear first wall 3a of the terminal storage portion 3. In addition, the first locking portion 33A of the holding portion 7 is provided on the left second wall 3b of the terminal storage portion 3. The second locking portion 33B of the holding portion 7 is provided on the right second wall 3b of the terminal storage portion 3. With this configuration, the entire circumference of the terminal storage portion 3 can be stably held by the holding portion 7 to the base plate 2.

[0059] According to the assembly 1 of this embodiment, as shown in Figure 5, a support portion 34 is provided on the left second wall 3b of the opposing second walls 3b, 3b, and the first locking portion 33A is supported on the left second wall 3b via the support portion 34. The support portion 34 is elastically deformable. With this configuration, by elastically deforming the support portion 34, the first locking portion 33A on the left second wall 3b can be inserted into the receiving portion 12, and the second locking portion 33B on the right second wall 3b can also be inserted into the receiving portion 12. Furthermore, after inserting the first locking portion 33A and the second locking portion 33B into the receiving portion 12, the first locking portion 33A and the second locking portion 33B can be locked to the back surface of the restricting portion 31 by elastically deforming the support portion 34. Therefore, the terminal storage portion 3 can be securely held on the base plate 2 by the holding portion 7.

[0060] According to the assembly 1 of this embodiment, as shown in Figures 2 and 5, the terminal housing section 3 is assembled to the base plate 2 from the surface 2a side with the first terminal 4A and the second terminal 4B housed inside. With this configuration, when assembling the terminal housing section 3 to the base plate 2, it is conceivable that the first terminal 4A may move within the first housing hole 25A of the terminal housing section 3 or come out of the first housing hole 25A. Similarly, it is conceivable that the second terminal 4B may move within the second housing hole 25B of the terminal housing section 3 or come out of the second housing hole 25B.

[0061] Therefore, the terminal storage section 3 is equipped with a terminal holding section 8, which holds the first terminal 4A stored in the first storage hole 25A. The terminal holding section 8 also holds the second terminal 4B stored in the second storage hole 25B. With this configuration, when assembling the terminal storage section 3 to the base plate 2, the first terminal 4A and the second terminal 4B can be reliably held in the state where they are stored in the terminal storage section 3.

[0062] As shown in Figures 4 and 5, the terminal holding portion 8 specifically includes a first holding piece 41 and a second holding piece 42 in the terminal housing portion 3. The first holding piece 41 has a pair of first projections 41A that can contact the tip of the first terminal 4A. The second holding piece 42 has a first locking piece 42A that can lock into the locking hole 27 of the first terminal 4A, thereby preventing the first terminal 4A 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 4B. The second holding piece 42 has a second locking piece 42B that can lock into the locking hole 28 of the second terminal 4B, thereby preventing the second terminal 4B from coming out of the locking hole 28 toward the base end.

[0063] With this configuration, the first terminal 4A 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 3. Similarly, the second terminal 4B 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 3.
