Abstract
A connector fitting body (1) has a first housing (2) holding first terminals (21), a second housing (3) holding second terminals (31) to be conductive with the first terminals (21), a nut (5) arranged in a nut arrangement hole (32) in the second housing (3), and a bolt (4) arranged in a bolt arrangement hole (22) in the first housing (2) and engaged threadedly with the nut (5). A head (41) of the bolt (4) includes a large-diameter portion (411) serving as a first step for pressing the first housing (2) toward the second housing (3). The nut (5) includes a general portion (51) serving as a second step for pressing the second housing (3) toward the first housing (2). An end surface of the head (41) is in contact with an end surface of the nut (5).
Claims7
A connector fitting body, comprising:
- a first housing holding first terminals and having a bolt arrangement hole, a first projection projecting into the bolt arrangement hole and having opposite first and second surfaces;
- a second housing holding second terminals to be brought into contact and conduction with the first terminals, the second housing being fit to the first housing and being formed with a nut arrangement hole;
- a nut arranged in the nut arrangement hole in the second housing;
- and
- a bolt arranged in the bolt arrangement hole in the first housing so that the bolt is spaced from the first and second terminals, the bolt including a head and a shaft coaxially connected to the head, the shaft being engaged threadedly with the nut, wherein:
- the first surface of the first projection faces away from the second housing,
- the head of the bolt includes a large diameter portion and a small diameter portion adjacent to the large diameter portion, a first step formed on the large diameter portion adjacent to the small diameter portion and engaging the first surface of the first projection for pressing the first housing toward the second housing,
- the nut includes a second step for pressing the second housing toward the second surface of the first projection of the first housing without direct contact between the second housing and the second surface of the first projection, and
- an axial end surface of the nut is aligned with an axial surface of the second housing facing the first housing and is in contact with an end surface of the head.
A connector fitting body, comprising:
- a first housing holding first terminals and having a bolt insertion hole, a first projection projecting into the bolt arrangement hole and having opposite first and second surfaces;
- a second housing holding second terminals to be brought into contact and conduction with the first terminals, the second housing being fit to the first housing and being formed with a nut arrangement hole;
- a nut arranged in the nut arrangement hole in the second housing;
- a bolt arranged in the bolt arrangement hole in the first housing, the bolt including a head and a shaft coaxially connected to the head, the shaft being engaged threadedly with the nut;
- and
- a collar made of metal arranged between an outer periphery of the shaft and an inner periphery of the bolt insertion hole and between the head of the bolt and the nut,
- wherein:
- the bolt and the collar are spaced from the first and second terminals,
- the first surface of the first projection faces away from the second housing,
- the collar includes a first step engaging the first surface of the first projection for pressing the first housing toward the second housing,
- the nut includes a second step for pressing the second housing toward the second surface of the first projection of the first housing, and
- an end surface of the nut is aligned with a surface of the second housing facing the first housing and is in contact with an end surface of the collar.
