Connector and device equipped with the same
View Patent ↗A connector capable of setting a direction of running a cable connected thereto, as desired. An angle end bell has eight positioning protrusions formed on a foremost end of a surrounding portion thereof at circumferentially equally-spaced intervals. Eight positioning recesses for engagement with the positioning protrusions are formed in a rear end of a barrel. The barrel has three erroneous fitting-preventing key grooves formed in an outer peripheral surface thereof at circumferentially equally-spaced intervals.
1. A connector for being fitted to a mating connector in a predetermined fitting direction, comprising:
a connector body including a contact which has a cable connected thereto, and a housing for holding said contact;
an end bell including a surrounding portion which surrounds at least part of said housing, a cable running portion which is connected to said surrounding portion, for running the cable in a direction at right angles to the fitting direction, and an end bell-side locking portion which is formed on an outer peripheral surface of said surrounding portion;
a barrel including an erroneous fitting-preventing portion which prevents erroneous fitting of the connector to the mating connector, and is coaxially abutted against a foremost end of said surrounding portion such that said barrel covers a remaining part of said housing;
barrel rotational position-determining means for determining a relative position of said barrel with respect to said end bell in a rotational direction, thereby causing the position of said erroneous fitting-preventing portion in the rotational direction to correspond to a position of said contact; and
a coupling nut including a first coupling nut-side locking portion which is engaged with said end bell-side locking portion, and a second coupling nut-side locking portion which is engaged with a mating connector-side locking portion provided on the mating connector, for locking the mating connector, said coupling nut covering said end bell and said barrel, and causing said barrel to abut against said end bell.
2. A connector as claimed in claim 1 , wherein said barrel rotational position-determining means comprises a plurality of positioning protrusions, and a plurality of positioning recesses associated with said positioning protrusions.
3. A connector as claimed in claim 1 , wherein said end bell-side locking portion is a locking nail, said first coupling nut-side locking portion being a locking hole, said second coupling nut-side locking portion being a locking piece having a hole for engagement with the mating connector-side locking portion.
4. A connector as claimed in claim 1 , wherein said connector body has a shield member for covering said housing, the cable having a shielding wire, the shielding wire being electrically connected to said shield member.
5. A connector as claimed in claim 4 , wherein said end bell has an end bell-side fitting portion formed thereon such that said end bell-side fitting portion extends along one end of the cable,
wherein said coupling nut has a coupling nut-side fitting portion formed thereon for being fitted to said end bell-side fitting portion, and
wherein a gland nut is mounted on said end bell and said coupling nut in a state in which said gland nut has received said end bell-side fitting portion and said coupling nut-side fitting portion.
6. A connector as claimed in claim 5 , further comprising:
a first seal member disposed between said end bell and said barrel, for sealing between said end bell and said barrel; and
a second seal member mounted on one end of the cable, for sealing between the cable and said end bell and between the cable and said gland nut.
7. A connector as claimed in claim 1 , wherein said contact includes a cable connecting portion soldered to a cable conductor of the cable, and
wherein said housing includes a contact holding portion for holding said contact in a state in which said cable connecting portion is exposed, and a cable holding portion for holding one end of the cable and positioning the cable conductor with respect to said cable connecting portion.
8. A connector as claimed in claim 7 , wherein said contact holding portion and said cable holding portion are integrally formed.
9. A connector as claimed in claim 7 , wherein said contact has a generally plate-like shape.
10. A connector as claimed in claim 9 , wherein said cable connecting portion has a central portion formed with a recess for positioning the cable conductor.
11. A connector as claimed in claim 7 , wherein said cable holding portion has a sloping surface formed thereon for soldering.
