When the cover 32 is rotated so that the lower wall 325 approaches the lower wall 313 of the case body 31 and the right opening of the case body 31 is closed, the locking arm 326 is inserted into the insertion hole 318. Then, when the tip of the locking arm 326 reaches the recess 319, it locks to the inner surface of the recess 319 of the locking projection 327.

[0021] Next, the assembly procedure of the above-described electrical connection box 1A will be described. First, nuts N are fixed to the nut fixing portions 316 and 317 of the case body 31. Next, the bus bar 2 is overlapped on the nut fixing portions 316 and 317. At this time, the rear screw insertion hole HS provided in the bus bar 2 and the nut N fixed to the nut fixing portion 316 face each other in the left-right direction, and the front screw insertion hole HS and the nut N fixed to the nut fixing portion 317 face each other in the left-right direction. The bus bar 2 is overlapped so that they face each other.

[0022] Next, the first electric wire L1 and the second electric wire L2 are attached. First, the attachment of the first electric wire L1 will be described. The terminal fitting T1 of the first electric wire L1 is overlapped on the bus bar 2. At this time, the screw insertion hole of the terminal fitting T1 and the rear screw insertion hole HS provided in the bus bar 2 are overlapped.

[0023] Also, the terminal fitting T1 is overlapped so that the terminal fitting T1 is on the front side, the first electric wire L1 is on the rear side, and the longitudinal direction of the first electric wire L1 is parallel to the front-back direction. Then, with the screw Sc passed through the screw insertion hole of the terminal fitting T1 and the rear screw insertion hole HS of the bus bar 2, it is screwed into the nut N fixed to the nut fixing portion 316. Thereby, the case body 31 can be tightened together with the bus bar 2 and the terminal fitting T1 attached to the end of the first electric wire L1. Further, the first electric wire L1 is taken out of the case body 31 through the rear opening 315.

[0024] Next, the attachment of the second electric wire L2 will be described. Place the terminal fitting T1 of the second electric wire L2 on top of the bus bar 2.

Also, stack the terminal fitting T1 so that the rear side of the terminal fitting T1 faces the rear and the second electric wire L2 faces the front, and the longitudinal direction of the second electric wire L2 is parallel to the front-rear direction. Next, pass the screw Sc through the screw insertion hole of the terminal fitting T1 and the front screw insertion hole HS of the bus bar 2, and then thread it into the nut N fixed to the nut fixing portion 317. This allows the case body 31 to clamp the bus bar 2 and the terminal fitting T1 attached to the end of the second electric wire L2 together. Also, the second electric wire L2 is taken out of the case body 31 through the front opening 315.

[0026] When connecting the additional electric wire L3, as shown in Fig. 2, open the cover 32 to open the right side of the case body 31. Then, insert the connector C1 provided at the end of the additional electric wire L3 into the case body 31 through the right opening of the case body 31, and bring the connector C1 closer to the terminal portion 24 of the bus bar 2 from the front side to the rear side. As a result, as shown in Fig. 3, the connector C1 is connected to the terminal portion 24. Specifically, fit the terminal fitting T2 housed in the housing H to the terminal portion 24. When the connector is connected, the connector C1 is arranged on the rear side, the additional electric wire L3 is on the front side, and the longitudinal direction of the additional electric wire L3 is parallel to the front-rear direction. The additional electric wire L3 is taken out of the case body 31 through the front opening 315 under the nut fixing portion 317. Then, as shown in Fig. 4, close the cover 32 to block the right opening of the case body 31. This completes the assembly of the electrical connection box 1A with the additional electric wire L3 added.
