Connection body

A connection body comprising:

• a header;
• and
• a plug harness which is fitted to the header, wherein
• the header includes
• a first housing which is made of an insulating material and has a pair of first hole portions formed in parallel with each other in a penetrating manner and a first bolt insertion portion formed between the pair of first hole portions in parallel with the pair of first hole portions,
• a pair of first terminals which have first contact surfaces on one ends thereof and have first contact portions having flat plate shapes to be able to be inserted into the respective first hole portions from a first contact surface side,
• a first holding member which is made of an insulating material and has a pair of first pressing portions for pressing each of the first terminals from a surface side opposite to the first contact surfaces to the first contact surface side in a first state in which the first terminals are inserted into the respective first hole portions from the first contact surfaces, a connecting portion for connecting the first pressing portions to each other, and a nut insertion portion formed in the connecting portion, and
• a nut which has a nut portion and a flange portion, the nut portion having a first end portion inserted into the nut insertion portion from a side opposite to a side on which the first pressing portions press and a second end portion opposite to the first end portion, the flange portion being made of metal and being fixed to the second end portion and engaging with a predetermined portion of the first housing so as to press the connecting portion from the side opposite to the side on which the first pressing portions press, and
• the plug harness includes
• a second housing which is made of an insulating material, can be fitted to the first housing, and has a pair of second hole portions formed in parallel with each other so that at least portions thereof face the first contact surfaces when the plug harness is fitted to the header, an opening portion formed so as to encompass a portion of each of the second hole portions and open in one direction of a first axis, the first axis intersecting with a hole direction of the second hole portions, and a second bolt insertion portion formed between the pair of second hole portions in parallel with the first axis,
• a pair of second terminals which have second contact portions on one ends thereof, the second contact portions having flat plate shapes to be able to be inserted into the respective second hole portions, and
• a second holding member which is made of metal and has a second pressing portion used for pressing a predetermined region of a first surface in the one direction, the first surface being an outer surface of the second housing and having the second bolt insertion portion formed therein, and a third bolt insertion portion penetrating through the second pressing portion, and
• a positional relationship between the nut portion, the first bolt insertion portion, the second bolt insertion portion, and the third bolt insertion portion is a positional relationship which allows fastening of the bolt and the nut by insertion of a single bolt in a second state in which the pair of first pressing portions are allowed to press the respective first terminals, the pair of second terminals are inserted into the respective second hole portions provided in pair, the first housing and the second housing are fitted to each other in a manner in which each of the first hole portions and the opening portion face each other, the second pressing portion of the second holding member is mounted on the predetermined region, and the first pressing portions of the first holding member are allowed to be abutted on respective surfaces, the surfaces being on an opposite side to the first contact surfaces of the first terminals, in the first state, and the fastening makes the first contact portions and the respective second contact portions conductive.
