Board connector and device
A board connector 10 to be mounted on a circuit board 50 is provided with a connector housing 11 including a receptacle 15 and a back wall 30 provided on a side opposite to an opening direction of the receptacle 15 , a mating connector 70 being fit into the receptacle 15 , an outer conductor 20 disposed in an outer conductor mounting hole 34 formed to penetrate through the back wall 30 , an insulating dielectric 19 disposed inside the outer conductor 20 , and an inner conductor 18 disposed inside the dielectric 19 . The outer conductor 20 includes a closing portion 25 for closing a mold removal hole 32 formed at a position of the back wall 30 different from the outer conductor mounting hole 34.
1. A board connector to be mounted on a circuit board, comprising:
a connector housing including a receptacle having an opening facing a front direction and a back wall facing a rear direction and provided on a side opposite to the opening of the receptacle, the back wall including an outer conductor mounting hole and a through hole;
a mating connector configured to fit into the receptacle;
an outer conductor inserted in the outer conductor mounting hole to penetrate through the back wall;
an insulating dielectric disposed inside the outer conductor; and
an inner conductor disposed inside the dielectric,
wherein the outer conductor includes a flange configured to contact the back wall, the flange including a closing portion for closing the through hole, the through hole being formed at a position of the back wall different from the outer conductor mounting hole.
2. The board connector of claim 1 , wherein:
the outer conductor includes a tubular portion extending in the front direction and configured to accommodate at least a part of the inner conductor, and
the flange is provided on an outer periphery of the tubular portion.
3. The board connector of claim 2 , wherein the connector housing and the outer conductor are positioned by fitting a locking projection provided on one of the back wall and the flange and a locking recess provided in the other.
4. The board connector of claim 3 , wherein:
the locking recess is provided in the flange,
the locking recess includes a small-diameter portion on the back wall side and a large-diameter portion provided on a side opposite to the back wall and having a larger diameter than the small-diameter portion, and
the locking projection is filled in the locking recess.
5. The board connector of claim 4 , wherein the large-diameter portion has a tapered surface expanded in diameter with distance from the back wall.
6. A device, comprising:
the board connector of claim 1 ;
a circuit board having the board connector mounted thereon; and
a case made of metal for accommodating the circuit board, the case being electrically connected to the outer conductor.
