[0030] To manufacture such a busbar 4, as shown in FIG. 2, a metal plate is stamped and punched to form a punched member (not shown). Then, the boundary between the connecting portion main body 60 and the upper continuous plate 61 in the connecting portion 6 is bent so that the upper connecting body 2 and the lower connecting body 3 face each other, and the boundary between the connecting portion main body 60 and the lower continuous plate 62 in the connecting portion 6 is bent. Furthermore, the boundary between the first plate-shaped portion 51A and the second plate-shaped portion 51B is bent so that the first plate-shaped portion 51A and the third plate-shaped portion 51C face each other, and the boundary between the second plate-shaped portion 51B and the third plate-shaped portion 51C is bent. In this manner, the busbar 4 is manufactured. That is, the busbar 4 is formed by stamping and punching the metal plate. When such a bus bar 4 is viewed from above Z1, the upper tab terminals 21 of the upper connecting body 2 and the lower tab terminals 31 of the lower connecting body 3 are arranged alternately in the width direction Y.

[0032] 1 and 2, the housing body 71 is configured in a rectangular cylindrical shape and has an upper wall 71A, a lower wall 71B, and a pair of side walls 71C, 71C. The internal space of the housing body 71 is divided by upper and lower partition walls 71D, and is provided with an upper link body accommodating section 7A for accommodating the upper link body 2 and a lower link body accommodating section 7B for accommodating the lower link body 3.

[0033] 4, the upper connecting body accommodating portion 7A and the lower connecting body accommodating portion 7B each have a plurality of terminal accommodating portions 70 for accommodating the tab terminals 21, 31. Each terminal accommodating portion 70 is formed by dividing each connecting body accommodating portion 7A, 7B in the width direction Y by a widthwise partition wall 71E provided on the front X1 side of the connecting body accommodating portion.

[0034] Each terminal accommodating portion 70 is open at the front X1 and the rear X2, and is configured so that each tab terminal 21, 31 is inserted through a rear opening (not shown) and a mating female terminal 11A that fits into each tab terminal 21, 31 is accommodated through a front opening 7f (shown in FIG. 4), thereby electrically connecting each tab terminal 21, 31 to the female terminal 11A. As shown in FIG. 4, each terminal accommodating portion 70 has a top surface 70A and a bottom surface 70B that face each other in the vertical direction Z. Each terminal accommodating portion 70 is provided with a lance 70C that engages the female terminal 11A.

When the bus bar 4 is accommodated in the housing 7, the rearward extending wall 711 faces the first plate-shaped portion 51A of the bus bar 4, and the downward extending wall 712 faces the second plate-shaped portion 51B of the bus bar 4.

[0037] The pair of upper support pieces 72, 72 are spaced apart in the width direction Y. Each upper support piece 72 protrudes downward Z2 from the upper wall 71A and is configured to abut against the upper base 20 of the upper connecting body 2 and press the upper connecting body 2 against the upper and lower partition walls 71D when the bus bar 4 is accommodated in the housing 7.

[0038] The pair of lower support pieces 73, 73 are provided at the same position as the pair of upper support pieces 72, 72 in the width direction Y. Each lower support piece 73 is provided to protrude downward Z2 and rearward X2 from the upper and lower partition walls 71D, and is configured to abut against the lower base portion 30 and the first plate-shaped portion 51A of the lower connecting body 3 and press the lower connecting body 3 against the lower wall 71B when the bus bar 4 is accommodated in the housing 7.

[0039] The pair of U-shaped accommodating sections 74, 74 are provided on both sides of the housing main body 71 in the width direction Y and protrude from the housing main body 71 in the width direction Y. Each U-shaped accommodating section 74 is U-shaped and has a first wall 74A and a second wall 74B that face each other in the up-down direction Z, and a third wall 74C that is continuous with the first wall 74A and the second wall 74B.

[0040] As shown in Figures 3 and 4, each press-fitting jig 8 is formed in a rectangular column shape and is configured to be able to enter the interior of each U-shaped housing portion 74. As shown in Figures 4 and 5, this press-fitting jig 8 is provided with a jig end face 8A that can come into contact with the inner surface 6a (shown in Figure 4) of the connecting portion main body 60 of each connecting portion 6, a jig upper face 8B that can come into contact with the inner surface 6b (shown in Figure 4) of the upper continuous plate 61, and a jig lower face 8C that can come into contact with the inner surface 6c (shown in Figure 4) of the lower continuous plate 62. The jig end face 8A is formed from a flat surface that includes the up-down direction Z and the width direction Y, and the jig upper face 8B and jig lower face 8C are formed from flat surfaces that include the front-rear direction X and the width direction Y.

[0041] Next, a procedure for manufacturing the connector 1 using a pair of press-fitting jigs 8, 8 will be described with reference to FIGS.

[0042] First, as shown in FIG. 3 , the tips of the tab terminals 21, 31 of the bus bar 4 are inserted close to each other into the rear openings of the terminal accommodating portions 70 of the housing 7. The connecting portions 6 of the bus bar 4 are then inserted close to each other into the pair of U-shaped accommodating portions 74, 74 of the housing 7. Then, the pair of press-fitting jigs 8 are moved simultaneously, approaching the space between the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6. As shown in FIG. 4 , the jig end surface 8A of each press-fitting jig 8 contacts (abuts against) the inner surface 6a of the connecting portion body 60 of each connecting portion 6 of the bus bar 4, the jig upper surface 8B contacts the inner surface 6b of the upper continuous plate 61 of each connecting portion 6, and the jig lower surface 8C contacts the inner surface 6c of the lower continuous plate 62 of each connecting portion 6. While the jig end surface 8A, jig upper surface 8B, and jig lower surface 8C of each press-fitting jig 8 remain in contact with the inner surfaces 6a, 6b, and 6c of each connecting portion 6, each press-fitting jig 8 continues to move, and each tab terminal 21, 31 reaches a predetermined position in each terminal accommodating portion 70 and is accommodated in each terminal accommodating portion 70 (shown in FIG. 5). Additionally, the upper connecting body 2 is accommodated in the upper connecting body accommodating portion 7A, and the lower connecting body 3 is accommodated in the lower connecting body accommodating portion 7B. Thereafter, each press-fitting jig 8 is pulled out from between the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6. In this manner, the connector 1 is assembled.

[0043] Thereafter, the female terminal 11A of the terminal-attached electric wire 11 is inserted into the terminal accommodating portion 70 from the front opening 7f of the housing 7, and inside each terminal accommodating portion 70, each tab terminal 21, 31 and each female terminal 11A are electrically connected.

[0044] Thereafter, the vehicle body fixing portion 5 of the bus bar 4 is brought into opposition to a predetermined position on the vehicle body panel. The stud bolts protruding from the vehicle body panel are inserted into the bolt insertion holes 52 of the bus bar 4, and the fourth plate-shaped portions 51D of the vehicle body fixing portion 5 are inserted into slits provided in the vehicle body panel. Thereafter, nuts are screwed onto the stud bolts, thereby fixing the vehicle body fixing portion 5 to the vehicle body panel. In this manner, the connector 1 is fixed to the vehicle body panel. With the connector 1 fixed to the vehicle body panel, the current that has traveled through each terminal-equipped electric wire 11 is grounded to the vehicle body panel via the bus bar 4.

[0045] Next, the effects of this embodiment will be described. Fig. 6 is a diagram illustrating a comparative example of this embodiment. As shown in Fig. 6, when the bus bar 4 is press-fitted into the housing 7 without using the press-fitting jig 8, the tip of each upper tab terminal 121 is likely to be deformed so as to point obliquely upward. However, in this embodiment, the press-fitting jig 8 enters between the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6, and the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6 are spaced apart from each other while the tab terminals 21, 31 are accommodated in the terminal accommodating portions 70. As a result, as shown in Fig. 5, the tip of each upper tab terminal 21 is accommodated in the terminal accommodating portion 70 with the tip extending straight.

[0046] According to the above-described embodiment, the press-in jig 8 is formed in the shape of a plate that can enter between the upper continuous plate 61 and the lower continuous plate 62 (a pair of extending portions), and is provided with a jig end face 8A (first surface) that can contact the connecting portion 6, a jig upper surface 8B (second surface) that is continuous with one end of the jig end face 8A, and a jig lower surface 8C (third surface) that is continuous with the other end of the jig end face 8A, and when the press-in jig 8 enters between the upper continuous plate 61 and the lower continuous plate 62, the jig end face 8A comes into contact with the connecting portion main body 60 (continuous portion), the jig upper surface 8B comes into contact with the upper continuous plate 61 (one of the pair of extending portions), and the jig lower surface 8C comes into contact with the lower continuous plate 62 (the other of the pair of extending portions). With this, the press-fitting jig 8 enters between the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6, and the upper continuous plate 61 and the lower continuous plate 62 of each connecting portion 6 are kept at a constant distance from each other, and the tab terminals 21, 31 are accommodated in the terminal accommodating portions 70, so that the upper tab terminal 21 in particular can be press-fitted without being deformed. In other words, deformation of the tab terminals 21, 31 can be suppressed.

[0047] Furthermore, the lower connecting body 3 (the other of the pair of connecting bodies) has a vehicle body fixing portion 5 that is continuous with the base portion 30 and extends rearward X2 (away from the tab terminals) to be fixed to a vehicle body panel. That is, compared to the lower connecting body 3, the upper connecting body 2 does not have a vehicle body fixing portion 5 and is cantilevered, so that the upper base portion 20 is easily tilted and the tips of the upper tab terminals 21 are easily deformed so as to point diagonally upward, but by being press-fitted using the press-fitting jig 8, a configuration can be realized in which the upper tab terminals 21 can be press-fitted without deforming them.

[0048] Although the best configurations and methods for carrying out the present invention have been disclosed above, the present invention is not limited thereto. That is, although the present invention has been particularly illustrated and described mainly with reference to specific embodiments, those skilled in the art can make various modifications to the above-described embodiments in terms of shape, material, quantity, and other detailed configurations without departing from the scope of the technical idea and purpose of the present invention. Therefore, the above-disclosed descriptions limiting the shape, material, etc. are provided as examples to facilitate understanding of the present invention and are not intended to limit the present invention. Therefore, descriptions using names of components that are free from some or all of the limitations on shape, material, etc. are included in the present invention. [Explanation of symbols]
