Tuner having a frame with a through-hole and a stopper to control a rotation of a connection portion mounted therein
View Patent ↗A tuner comprises a frame that is provided with a through-hole and a connection portion to which a connector is connected. The connection portion includes a flange portion that is able to select to pass through the through-hole or not to pass through the through-hole by the connection portion being rotated, and the frame includes a pressurization portion that pressurizes the flange portion which passes through the through-hole.
1. A tuner comprising:
a frame that is provided with a through-hole;
a connection portion that includes a main body portion protruding out of the frame and a planar portion connected to the main body portion; and
a circuit board that is mounted on the frame and electrically connected to the connection portion; wherein
the planar portion passes through the through-hole when the connection portion is rotated to a first position, and does not pass through the through-hole when the connection portion is rotated to a second position, and
the frame includes a stopper that associates with the planar portion to control a rotation of the connection portion to one direction when the connection portion is disposed in the first position in which the planar portion passes through the through-hole.
2. The tuner according to claim 1 , wherein
the frame includes a pressurization portion that pressurizes the planar portion within the frame.
3. The tuner according to claim 2 , wherein
the pressurization portion changes a pressurization force for pressurizing the planar portion in accordance with a rotation amount of the connection portion.
4. The tuner according to claim 2 , wherein
the frame includes a first side wall and a second side wall that meets the first side wall at right angles; wherein
the through-hole is disposed through the first side wall; and
the pressurization portion is disposed on the second side wall in an elastically deformable manner and pressurizes the planar portion from a side surface.
5. The tuner according to claim 4 , wherein
the pressurization portion is formed by cutting away a portion of the second side wall.
6. The tuner according to claim 1 , wherein
the planar portion has a first direction for passing through the through-hole and a second direction for not-passing through the through-hole.
7. The tuner according to claim 6 , wherein
the planar portion has a flange shape.
8. The tuner according to claim 6 , wherein
the planar portion includes two straight line portions opposing each other and two are portions opposing each other.
9. The tuner according to claim 6 , wherein
the planar portion has a point-symmetrical shape.
10. The tuner according to claim 6 , wherein
the through-hole has a shape similar to the planar portion in a plan view.
11. The tuner according to claim 10 , wherein
the through-hole is slightly larger than the planar portion in a plan view.
12. The tuner according to claim 10 , wherein
the through-hole includes a cut-away portion.
13. The tuner according to claim 12 , wherein
the cut-away portion has an arc shape in a plan view.
14. The tuner according to claim 1 , wherein
the through-hole has point-symmetrical shape.
15. The tuner according to claim 6 , wherein
the connection portion includes a core-line connection metal fitting a portion of which protrudes from the main body portion.
16. The tuner according to claim 15 , wherein
the connection portion further includes a link portion that links the planar portion to the main body portion.
17. The tuner according to claim 1 , wherein
the frame is provided with at least one additional through-hole and at least one additional connection portion.
18. A broadcast reception apparatus comprising the tuner according to claim 1 .
