Description

Technical Field

[0001] This invention relates to resin bodies and electrical connection boxes. Background Technology

[0002] Previously, an electrical connection box has been proposed, which is mounted in a vehicle and houses various electronic components such as fuses, relays, and electronic control units within its internal space. For example, a conventional electrical connection box includes: a frame having an internal space; a columnar bolt disposed within the internal space of the frame and electrically connected to the electronic components; and a side cover mounted to the frame at the location of the columnar bolt (see, for example, Patent Document 1).

[0005] Patent Document 1: Japanese Patent Application Publication No. 2013-74655 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] However, before the aforementioned side cover is assembled into the frame of the electrical connection box, a wire with terminals, including wires and L-shaped terminals, is assembled. Therefore, to suppress terminal wobbling, a locking part is provided in the side cover to lock the terminals in place. On the other hand, to suppress terminal wobbling, it is preferable to configure the locking part to be in close contact with the terminals. However, since the terminals are L-shaped, from the viewpoint of assembling the wire with terminals into the side cover, a gap is provided between the locking part and the terminals. Therefore, it may not be possible to sufficiently suppress terminal wobbling, and thus, positioning the terminals relative to the column bolts may become difficult. In addition, if terminal wobbling is not sufficiently suppressed, it may be difficult to pull the wire in the desired direction when trying to lead the wire with terminals in the desired direction, causing the terminals to wobble.

[0008] The present invention was made in view of the above circumstances, and its object is to provide a resin body and an electrical connection box that can effectively suppress the shaking of terminals in a wire with terminals.

[0009] Technical means for solving problems

[0010] To achieve the above objectives, the resin body involved in this invention has the following characteristics.

[0011] A resin body is configured to hold a terminald wire having L-shaped terminals, the terminals including wire-side connecting portions and mating-side connecting portions. The resin body is assembled into a frame that houses electronic components therein.

[0012] The resin body is integrally formed with:

[0013] A first wall portion, the first wall portion extending along a first direction; and

[0014] A pair of second wall portions, separately configured in a second direction intersecting the first direction, are capable of restricting the displacement of the terminal in the second direction.

[0015] Each of the two second wall portions is provided with:

[0016] The mounting portion, which is capable of mounting the mating side connecting portion; and

[0017] A first limiting part, together with the mounting part, clamps the mating side connection part along the first direction in a manner that restricts the displacement of the terminal in the first direction.

[0018] The first wall portion is provided with:

[0019] A second limiting portion, which, together with the mounting portion, clamps the mating-side connecting portion along the third direction to restrict the terminal from displacing upward in a third direction intersecting the first and second directions; and

[0020] The third limiting part, together with the mounting part, clamps the mating side connection part along the first direction in a manner that restricts the displacement of the terminal in the first direction.

[0021] To achieve the above objectives, the electrical connection box involved in this invention has the following features.

[0022] An electrical connection box includes: the resin body; wires with terminals; and a frame housing electronic components inside.

[0023] The terminald wire has a wire and an L-shaped terminal.

[0024] The terminal is integrally formed with:

[0025] A wire-side connection portion, the wire-side connection portion extending along the first direction and connected to the wire; and

[0026] A mating side connection portion extends along the third direction and is connected to a columnar bolt disposed on the frame.

[0027] Invention Effects

[0028] The resin body and electrical connection box involved in this invention will be described below.

[0029] According to the resin body and electrical connection box of this structure, a pair of second wall portions clamp the mating side connection portion along the second direction, thereby restricting the displacement of the terminal in the second direction. Similarly, the mounting portion and the first limiting portion, and the mounting portion and the third limiting portion respectively clamp the mating side connection portion along the first direction, thereby restricting the displacement of the terminal in the first direction. Similarly, the mounting portion and the second limiting portion clamp the mating side connection portion along the third direction, thereby restricting the displacement of the terminal in the third direction. In this way, the resin body of this structure can suppress terminal wobble by restricting the displacement of the terminal in all directions.

[0030] The present invention has been briefly described above. Furthermore, the details of the invention will become more apparent from the following detailed embodiments (hereinafter referred to as "embodiments") with reference to the accompanying drawings. Attached Figure Description

[0047] <Implementation Method>

[0048] The following, with reference to the attached drawings, describes... Figure 1 The side cover 40 according to the embodiment of the present invention shown will be described. The side cover 40 is a resin molded body assembled to the side wall portion 11 of the electrical connection box 1. The electrical connection box 1 is typically mounted in a vehicle and is a relay box with an internal space. This internal space houses electronic components such as relays, and electronic components R (see reference 1) as other components. Figures 2-3 ).

[0049] For ease of explanation, the following is as follows: Figure 1 As shown, "front," "rear," "left," "right," "up," and "down" are defined. The "front-rear direction," "left-right direction," and "up-down direction" are orthogonal to each other. When the electrical connection box 1 is mounted on a vehicle, the "front-rear direction," "left-right direction," and "up-down direction" correspond to the vehicle's front-rear direction, left-right direction, and up-down direction, respectively. Furthermore, the up-down direction corresponds to the "first direction" of this invention. Additionally, the left-right direction corresponds to the "second direction" of this invention. Moreover, the front-rear direction corresponds to the "third direction" of this invention.

[0050] like Figure 1As shown, the electrical connection box 1 is composed of a frame 10, a lower cover 20 assembled below the frame 10 to close the lower opening of the frame 10, an upper cover 30 assembled above the frame 10 to close the upper opening of the frame 10, and a side cover 40 (corresponding to the "resin body" of the present invention) assembled to the side wall portion 11 of the frame 10. All four components constituting the electrical connection box 1 are resin molded bodies.

[0051] In electrical connection box 1, such as Figure 1 As shown, a wire (not shown) that is electrically connected to a portion of an electronic component R located inside the electrical connection box 1 is led out to the outside of the electrical connection box 1 via a wire lead-out hole (not shown) provided at the rear left of the electrical connection box 1. Furthermore, a wire (not shown) that is electrically connected to a portion of another electronic component R is led out to the outside of the electrical connection box 1 via a wire lead-out hole (not shown) provided at the front right of the electrical connection box 1.

[0052] Furthermore, the terminal wire 50 held by the side cover 40 is connected and fastened to the stud bolt S provided in the internal space of the electrical connection box 1, and is led out to the outside of the electrical connection box 1 through the receiving part 42 of the side cover 40.

[0053] The terminald wire 50 consists of a wire 51 and a terminal 52 connected to the end of the wire 51 (see reference). Figures 2-3 One end of wire 51 is connected to terminal 52, and the other end is connected, for example, to a battery, alternator, etc. Figures 2-3 , Figure 6 and Figures 8-9 As shown, terminal 52 is formed in a generally L-shape and integrally comprises: a wire-side connection portion 53 extending in the vertical direction and connected to wire 51; and a mating-side connection portion 54 extending forward and connected and fastened to a columnar bolt S. Furthermore, the mating-side connection portion 54 is provided with a hole extending in the vertical direction for the columnar bolt S to be inserted. Hereinafter, the frame 10, lower cover 20, upper cover 30, and side cover 40 constituting the electrical connection box 1 will be described in sequence.

[0054] First, let's explain framework 10. For example... Figure 1 As shown, the frame 10 has a generally rectangular cylindrical sidewall portion 11 extending in the vertical direction. The sidewall portion 11 constitutes most of the appearance of the side of the electrical connection box 1.

[0055] On the outer surface of multiple circumferential locations (eight locations in this example) at the lower end of the side wall portion 11, a locking portion 12 is integrally provided, each including a through hole extending in the vertical direction. The locking portion 12 functions to assemble the lower cover 20 to the frame 10. Additionally, on the outer surface of multiple circumferential locations (three locations in this example) at the upper end of the side wall portion 11, a locking portion 13 is integrally provided. The locking portion 13 functions to assemble the upper cover 30 to the frame 10.

[0056] A semi-cylindrical groove 14, opening downwards, is provided on the side wall portion 11 at the location corresponding to the wire outlet hole on the left rear side, inclined to the lower left. The groove 14 functions as the upper portion of the inner wall dividing the wire outlet hole on the left rear side. Furthermore, a semi-cylindrical groove 15, opening downwards, is provided on the side wall portion 11 at the location corresponding to the wire outlet hole on the right front side, extending to the right. The groove 15 functions as the upper portion of the inner wall dividing the wire outlet hole on the right front side.

[0057] Multiple circumferential portions of the lower end of the side wall portion 11 are integrally provided with downwardly extending support strip portions 16. The support strip portions 16 have the function of fixing the frame 10 (i.e., the electrical connection box 1) to the vehicle mounting position by assembling their ends to the vehicle mounting position.

[0058] An assembly portion 17 for assembling the side cover 40 is provided on the side wall portion 11 near the column bolt S (rear in this example). An assembly portion 17 is provided with a locking portion (not shown), which, for example, locks the side cover 40 (not shown).

[0059] Next, the lower cover 20 will be explained. For example... Figure 1 As shown, the lower cover 20 integrally comprises: an annular sidewall portion 21, which constitutes most of the appearance of the lower side surface of the electrical connection box 1; and a bottom wall portion 22, which closes the annular lower end opening of the sidewall portion 21 and constitutes most of the appearance of the bottom surface of the electrical connection box 1. The annular upper edge of the sidewall portion 21 has a shape corresponding to the annular lower edge of the sidewall portion 11 of the frame 10, and can be fitted with the annular lower edge of the sidewall portion 11.

[0060] On the outer surface of multiple circumferential locations (eight locations in this example) at the upper end of the side wall portion 21, locking pieces 23 extending upward are integrally provided, corresponding to multiple locking portions 12 of the frame 10.

[0061] A semi-cylindrical groove 24, opening upwards, is provided on the side wall portion 21 at the location corresponding to the wire outlet hole on the left rear. The groove 24 functions as the lower portion of the inner wall that divides the wire outlet hole on the left rear. Additionally, a semi-cylindrical groove 25, opening upwards, is provided on the side wall portion 21 at the location corresponding to the wire outlet hole on the right front. The groove 25 functions as the lower portion of the inner wall that divides the wire outlet hole on the right front.

[0062] Next, the top cover 30 will be explained. For example... Figure 1 As shown, the top cover 30 integrally comprises: an annular sidewall portion 31, which constitutes most of the appearance of the upper side surface of the electrical connection box 1; and an upper wall portion 32, which closes the annular upper opening of the sidewall portion 31 and constitutes most of the appearance of the upper surface of the electrical connection box 1. The annular lower edge of the sidewall portion 31 has a shape corresponding to the annular upper edge of the sidewall portion 11 of the frame 10, and can be fitted with the annular upper edge of the sidewall portion 11. On the outer surface of multiple circumferential portions (three portions in this example) of the sidewall portion 31, locking portions 33 are integrally provided, corresponding to multiple locking portions 13 of the frame 10.

[0063] Next, the side cover 40 will be described. For example... Figures 2 to 5 As shown, the side cover 40 is integrally formed with a first wall portion 41 extending in the vertical direction and a pair of second wall portions 43 separately arranged in the horizontal direction. Thus, the side cover 40 defines a receiving portion 42 for a wire 50 with a terminal, which is open in the front and vertical directions.

[0064] In this embodiment, the second wall portion 43 is respectively provided at the left and right ends and the approximately central region in the left-right direction of the first wall portion 41. Thus, a pair of receiving portions 42 are arranged adjacent to each other in the left-right direction. Furthermore, regarding the second wall portion 43 in the approximately central region in the left-right direction, its lower vertical region is integrally formed.

[0065] That is, the first wall portion 41 functions as a so-called bottom wall, the second wall portions 43 at both ends in the left and right directions function as so-called side walls, and the second wall portion in the roughly central area in the left and right directions functions as a partition wall for adjacent receiving portions 42. Furthermore, the second wall portion 43 functions to restrict the displacement of the terminal 52 (particularly the mating side connection portion 54) in the left and right directions while holding the terminald wire 50 (see reference). Figure 7 ).

[0066] Furthermore, the first wall portion 41 is composed of a first portion 41a located in the lower region in the vertical direction, a second portion 41b located in the upper region in the vertical direction, and a third portion 41c located between the first portion 41a and the second portion 41b. Moreover, the first portion 41a is located further rearward than the second portion 41b. Thus, as will be described later, it is possible to suppress the shaking of the terminal 52 and ensure the space required for the assembly operation of the wire 50 with the terminal to the side cover 40.

[0067] Each of the second wall portions 43 is provided with a mounting portion 44 that protrudes inward toward the corresponding receiving portion 42. This mounting portion 44 mounts the mating side connection portion 54 of the wire 50 with terminals (see reference). Figures 4-5 Furthermore, each of the second wall portions 43 is provided with a first limiting portion 45 protruding towards the inner side of the corresponding receiving portion 42. This first limiting portion 45 is positioned above and in front of the mounting portion 44. The first limiting portion 45 functions to restrict the vertical displacement of the terminal 52 (particularly the mating portion 54) by clamping the mating side connecting portion 54 in the vertical direction together with the mounting portion 44 while holding the terminal wire 50 in place. Figure 6 ).

[0068] In the first wall portion 41 (specifically, the third portion 41c), at the portion corresponding to each receiving portion 42, a pair of second limiting portions 46 are provided in a forward-protruding manner. These pair of second limiting portions 46 are separately arranged in the left-right direction of the receiving portion 42 (see reference). Figure 4 The second limiting part 46 has the following function: while holding the wire 50 with terminals, it clamps the mating side connecting part 54 together with the mounting part 44 in the front-back direction, thereby limiting the displacement of the terminal 52 (especially the mating side connecting part 54) in the front-back direction (see reference). Figure 6 ).

[0069] In the first wall portion 41 (specifically, the second portion 41b), at the portion corresponding to each receiving portion 42, a pair of third limiting portions 47 are provided in a forward-protruding manner. These pair of third limiting portions 47 are arranged separately in the left-right direction (see reference). Figures 2 to 3 and Figures 5 to 6 The third limiting part 47 has the following function: by clamping the mating side connecting part 54 together with the mounting part 44 in the vertical direction, it restricts the displacement of the terminal 52 (especially the mating side connecting part 54) in the vertical direction (see reference). Figure 6 ).

[0070] The frame 10, lower cover 20, upper cover 30, and side cover 40 constituting the electrical connection box 1 have been described above. In order to assemble the electrical connection box 1, which includes the frame 10, lower cover 20, upper cover 30, and side cover 40, the lower cover 20, upper cover 30, and side cover 40 need to be assembled on the frame 10 respectively.

[0071] First, assemble the lower cover 20 to the frame 10. To assemble the lower cover 20 to the frame 10, attach the multiple locking tabs 23 of the lower cover 20 (see reference). Figure 1 Insert the locking part 12 of the frame 10 from below (see reference). Figure 1 The lower cover 20 has multiple through holes, and from this state, the annular upper edge of the side wall portion 21 of the lower cover 20 is fitted into the annular lower edge of the side wall portion 11 of the frame 10, and multiple locking pieces 23 are locked into multiple locking portions 12. Thus, the assembly of the lower cover 20 into the frame 10 is completed.

[0072] Next, the wire 50 with terminals is assembled to the side cover 40 (details to follow). Then, the side cover 40 is assembled to the frame 10. In order to assemble the side cover 40 to the frame 10, the wire 50 with terminals is connected and fastened to the column bolt S, and the side cover 40 is assembled to the assembly part 17 of the frame 10.

[0073] Specifically, the terminal 52 of the wire 50 with terminals is inserted through the hole 55 into the columnar bolt S, and then the nut N is tightened, thereby connecting and securing the wire 50 with terminals to the columnar bolt S. Afterwards, the locking part (not shown) of the side cover 40 is locked into the locking part (not shown) of the frame 10. Thus, the assembly of the side cover 40 to the frame 10 is completed.

[0074] Next, the top cover 30 is assembled to the frame 10. To assemble the top cover 30 to the frame 10, the annular lower edge of the side wall portion 31 of the top cover 30 is fitted into the annular upper edge of the side wall portion 11 of the frame 10, and the plurality of locking portions 33 of the top cover 30 are locked into the plurality of locking portions 12 of the frame 10. Thus, the assembly of the top cover 30 to the frame 10 is completed.

[0075] Therefore, the lower cover 20, the upper cover 30, and the side cover 40 are assembled onto the frame 10 to complete the electrical connection box 1. Furthermore, the order of the assembly process of the lower cover 20 onto the frame 10 and the assembly process of the side cover 40 onto the frame 10 is arbitrary.

[0076] With the electrical connection box 1 assembled, the lower cover 20 is prevented from separating downwards from the frame 10 by the locking of multiple locking tabs 23 and multiple locking parts 12. Similarly, the upper cover 30 is prevented from separating upwards from the frame 10 by the locking of multiple locking parts 33 and multiple locking parts 13. Furthermore, the side cover 40 is also prevented from separating rearwards from the frame 10 by the locking of the frame 10 (not shown) and multiple locking parts (not shown) of the side cover 40.

[0077] Furthermore, the outer surface of the assembled portion 17 of the frame 10 and the inner surface of the receiving portion 42 of the side cover 40 are used to divide the wire insertion path through which the terminal wire 50 is inserted (illustration omitted). Similarly, the slotted portion 14 of the frame 10 and the slotted portion 24 of the lower cover 20 are used to divide the wire outlet hole at the left rear where the power supply wire (illustration omitted) is inserted. Similarly, the slotted portion 15 of the frame 10 and the slotted portion 25 of the lower cover 20 are used to divide the wire outlet hole at the right front where the wire (illustration omitted) is inserted.

[0078] Next, refer to Figures 8-9 The assembly method of the terminald wire 50 to the side cover 40 is described. First, tilt the terminald wire 50 so that its upper end is tilted backward, and insert the mating side connecting part 54 into the gap between the mounting part 44 and the second limiting part 46 and between the mounting part 44 and the third limiting part 47 (see reference). Figure 8 ).

[0079] After inserting the mating-side connector 54 into the designated position, rotate the terminald wire 50 around the concave portion of the wire-side connector 53 and the mating-side connector 54, or the contact portion near the concave portion of the mounting portion 44, centered on the contact point (see reference). Figure 9 (The arrow). The mating side connection 54 passes over the first limiting part 45 from above to below during rotation and then reaches the designated position. Thus, the terminald wire 50 is assembled to the side cover 40. In other words, the terminald wire 50 is held by the side cover 40 (see reference). Figure 2 as well as Figures 6-7 ).

[0080] When the wire 50 with terminals is in the holding state, the mating side connection portion 54 is clamped by a pair of second wall portions 43 in the left-right direction, restricting the displacement of the terminal 52 in the left-right direction (see reference). Figure 7 Similarly, when the terminald wire 50 is in the holding state, the mating side connection portion 54 is clamped in the vertical direction by the mounting portion 44 and the first limiting portion 45, and the mounting portion 44 and the third limiting portion 47, respectively, thereby limiting the vertical displacement of the terminal 52 (see reference). Figure 6Similarly, when the terminald wire 50 is in the holding state, the mating side connection portion 54 is clamped in the front-rear direction by the mounting portion 44 and the second limiting portion 46, thereby limiting the displacement of the terminal 52 in the front-rear direction (see reference). Figure 6 ).

[0081] In addition, by providing a mounting portion 44 and a first limiting portion 45 at different positions in the front-rear direction for the mating side connection portion 54 extending in the front-rear direction, the side cover 40 can more appropriately suppress the shaking of the terminal 52 (especially the lifting of the front end of the mating side connection portion 54).

[0082] In this way, the side cover 40 can suppress the wobble of the terminal 52 by limiting the displacement of the terminal 52 in all directions. As a result, the positioning accuracy of the hole 55 of the terminal 52 in the wire 50 with terminal is improved. For example, when assembling the side cover 40 to the frame 10, the wire 50 with terminal can be easily connected and fastened to the column bolt S. In addition, since the wobble of the terminal 52 caused by the pulling of the wire 51 is suppressed, the wire 51 can be led out in the desired direction.

[0083] It should be noted that the assembly of the terminal wire 50 to the side cover 40 can be performed in a single action, resulting in excellent assembly workability.

[0084] <Other methods>

[0085] Furthermore, the present invention is not limited to the above embodiments, but can be appropriately modified and improved. In addition, the material, shape, size, quantity, and arrangement of the structural elements in the above embodiments can be arbitrary and not limited, as long as the present invention can be realized.

[0086] like Figure 10 As shown, the surface of the first limiting portion 45 opposite to the mating side connecting portion 54 (the lower end surface in this example) can also be formed in an inclined shape that approaches the mating side connecting portion 54 from the protruding end toward the protruding base end. Normally, a gap needs to be provided between the locking portion and the locked member locked in the locking portion. Therefore, the locked member may wobble in the amount of the gap. However, according to the above structure, even if a necessary gap is provided between the first limiting portion 45 and the mating side connecting portion 54, the gap can be reduced at the protruding base end of the first limiting portion 45, thus more appropriately suppressing the wobble of the terminal 52. Furthermore, the first limiting portion 145, which will be described later, can also be formed as described above.

[0087] <Variation Example>

[0088] The following is for reference Figures 11 to 16 The side cover 140 involved in the modified example of the above embodiment (side cover 40) will be described.

[0089] First, the specific structure of the side cover 140 will be explained. For example... Figures 11 to 13 As shown, the side cover 140 is integrally formed with: a first wall portion 141 extending in the vertical direction; and a pair of second wall portions 143 separately arranged in the horizontal direction. Thus, the side cover 140 defines a receiving portion 142 for a terminal wire 50 that opens in the front and vertical directions. That is, the first wall portion 141 functions as a so-called bottom wall, and the pair of second wall portions 143 functions as so-called side walls.

[0090] The first wall portion 141 is composed of a first portion 141a located in the lower region in the vertical direction, a second portion 141b located in the upper region in the vertical direction, and a third portion 141c located between the first portion 141a and the second portion 141b.

[0091] The second wall portion 143, like the second wall portion 43 in the above embodiment, has the function of restricting the displacement of the terminal 52 (especially the mating side connection portion 54) in the left and right directions while holding the wire 50 with the terminal.

[0092] Within the receiving portion 142, a mounting portion 144 is provided such that a pair of second wall portions 143 are connected in the left-right direction. This mounting portion 144 mounts the mating side connection portion 54 of the wire 50 with terminals (see reference). Figures 12-13 ).

[0093] On the second wall portion 143 on the left, a first limiting portion 145 is provided within the receiving portion 142 in a manner that protrudes to the right. This first limiting portion 145 is positioned above and in front of the mounting portion 144 (see reference). Figures 11 to 12 and Figures 14 to 16 The first limiting part 145 has the following function: while holding the wire 50 with terminals, it clamps the terminal 52 in the vertical direction together with the mounting part 144, thereby limiting the vertical displacement of the terminal 52 (especially the mating side connection part 54) (see reference). Figure 15 ).

[0094] In the first wall portion 141 (specifically, the third portion 141c), within the receiving portion 142, a pair of second limiting portions 146 are provided in a forward-projecting manner, the pair of second limiting portions 146 being separately arranged in the left-right direction (see reference). Figure 14 The second limiting part 146 has the following function: while holding the wire 50 with terminals, it clamps the terminal 52 together with the mounting part 144 in the front-back direction, thereby limiting the displacement of the terminal 52 (especially the mating side connection part 54) in the front-back direction (see reference). Figure 6 ).

[0095] In the first wall portion 41 (specifically, the second portion 41b), within the receiving portion 142, a pair of third limiting portions 147 are provided in a forward-protruding manner, and these pair of third limiting portions 147 are arranged separately in the left-right direction. The third limiting portions 147 have the following function: by clamping the mating side connecting portion 54 in the vertical direction together with the mounting portion 144, they limit the vertical displacement of the terminal 52 (especially the mating side connecting portion 54) (see reference). Figure 15 ).

[0096] A cutout 149 is provided on the second wall portion 143 on the right side. This cutout 149 is cut into a shape corresponding to the terminal 52 of the wire 50 with a terminal (see reference). Figures 11 to 13 as well as Figure 16 The cutout portion 149 is composed of a first cut portion 149a cut in a manner corresponding to the wire-side connection portion 53 of the terminald wire 50 and a second cut portion 149b cut in a manner corresponding to the mating-side connection portion 54 of the terminald wire 50. The first cut portion 149a and the second cut portion 149b are in communication with each other. The cutout portion 149 functions as an insertion port when the terminald wire 50 is received in the receiving portion 142.

[0097] In this example, the side cover 140 is described as having only one receiving portion 142, but multiple receiving portions 142 may also be arranged side by side in the left-right direction, as in the receiving portion 42 of the above embodiment. For example, in the case of two receiving portions 142, the cutout portions 149 are respectively provided on the right second wall portion 143 and the left second wall portion 143.

[0098] Next, the assembly method of the terminald wire 50 to the side cover 140 will be described. First, after positioning the terminald wire 50 on the right side of the side cover 140, tilt the upper end of the terminald wire 50 backwards, bringing the terminald wire 50 close to the side cover 140 (see reference). Figure 16 ).

[0099] Then, the terminald wire 50 is inserted into the receiving portion 142 through the cutout 149. After the terminald wire 50 is inserted into the receiving portion 142, the terminald wire 50 is rotated around the contact portion of the mounting portion 144 near the concave corner of the wire-side connecting portion 53 and the mating-side connecting portion 54. During the rotation, the mating-side connecting portion 54 passes the first limiting portion 145 from above to below and then reaches a predetermined position. Thus, the terminald wire 50 is assembled to the side cover 140. In other words, the terminald wire 50 is held by the side cover 140 (see reference). Figure 11 and Figure 15 Furthermore, the aforementioned rotation is performed in the direction that restores the tilt of the terminal wire 50.

[0100] When the wire 50 with terminals is in the holding state, the mating side connection portion 54 is clamped by a pair of second wall portions 143 in the left-right direction, restricting the displacement of the terminal 52 in the left-right direction (see reference). Figure 11 Similarly, when the terminald wire 50 is in the holding state, the mating side connection portion 54 is clamped in the vertical direction by the mounting portion 144 and the first limiting portion 145, and the mounting portion 144 and the third limiting portion 147, respectively, thereby limiting the vertical displacement of the terminal 52 (see reference). Figure 15 Similarly, when the terminald wire 50 is in the holding state, the mating side connection portion 54 is clamped in the front-rear direction by the mounting portion 144 and the second limiting portion 146, and the limiting terminal 52 is displaced in the front-rear direction (see reference). Figure 15 ).

[0101] In addition, by providing a mounting portion 144 and a first limiting portion 145 at different positions in the front-rear direction for the mating side connection portion 54 extending in the front-rear direction, the side cover 140 can more appropriately suppress the shaking of the terminal 52 (especially the lifting of the front end of the mating side connection portion 54).

[0102] In this way, the side cover 140 can suppress the wobble of the terminal 52 by limiting its displacement in all directions. As a result, the positioning accuracy of the hole 55 of the terminal 52 in the terminald wire 50 is improved. For example, when assembling the side cover 140 to the frame 10, the terminald wire 50 can be easily connected and secured to the column bolt S. Furthermore, since the wobble of the terminal 52 caused by the pulling of the wire 51 is suppressed, the wire 51 can be led out in the desired direction.

[0103] It should be noted that the assembly of the terminal wire 50 to the side cover 140 can be performed in a single action, resulting in excellent assembly workability.

[0104] Furthermore, since the wire 50 with terminals is inserted into the receiving portion 142 of the side cover 140 in the left-right direction, the front-back distance between the first portion 141a and the second portion 141b can be made closer compared to the embodiment described above. That is, miniaturization can be achieved in the side cover 140. Moreover, by providing a cutout 149 in the second wall portion 143, it is easy to receive the wire 50 with terminals into the receiving portion 142.

[0115] The third limiting parts 47 and 147, together with the mounting parts 44 and 144, clamp the mating side connecting part 54 along the first direction in a manner that restricts the displacement of the terminal 52 in the first direction.

[0116] [2] In the resin body (side cover 40, 140) described in [1] above,

[0117] The mounting portions 44 and 144 and the first limiting portions 45 and 145 are disposed at different positions in the third direction that is the extension direction of the mating side connecting portion 54.

[0118] [3] In the resin body (side cover 140) described in [1] or [2] above,

[0127] According to the resin body with the structure described above [2], the mounting portion and the first limiting portion are positioned at different locations in the third direction relative to the mating side connecting portion extending in the third direction, thereby enabling more appropriate suppression of terminal wobbling.
