Electronic package, display, and electronic device
An FPC board ( 1 ) is mounted on a front bezel (BZ 1 ) and a rear bezel (BZ 2 ). The outer claw (CW 1 ) of the front bezel (BZ 1 ) and the inner claw (CW 2 ) of the rear bezel (BZ 2 ) are engaged with each other while holding the ground portion ( 12 ) of the FPC board ( 1 ) therebetween.
1. An electronic package, comprising
a housing unit that is composed of a plurality of housings integrally engaged with each other, and
a circuit board that is incorporated in the housing unit, and that includes a supply conductor,
wherein
at least one of the housings that are engaged with each other is formed of electrically conductive material,
the housings include engagement portions that engage with each other to unite the housings,
the engagement portions are located on side walls of the housing unit, and
a ground portion in the circuit board is curved to cover a side wall of at least one of the housings and is held by and between the engagement portions.
2. The electronic package of claim 1 , wherein
the ground portion is film-shaped,
he engagement portions, which engage with each other, are claw-shaped, and
the claw-shaped engagement portions interlock with each other with the ground portion interposed therebetween.
3. The electronic package of claim 2 , wherein the claw-shaped engagement portions are fonned by raising cut portions formed in the housings.
4. The electronic package of claim 1 , wherein
the ground portion is film-shaped,
of the engagement portions engaging each other, one is a protrusion-shaped engagement portion, another is a recess-shaped engagement portion, and
the protrusion-shaped engagement portion and the recess-shaped engagement portion are engaged with each other with the film-shaped ground portion interposed therebetween.
5. The electronic package of claim 1 , wherein
the ground portion is a thin portion formed by raising a cut portion of the circuit board, and
the ground portion, which is thin, is pressed by a press member against the housings, which are formed of electrically conductive material.
6. A display comprising the electronic package of claim 1 .
7. The display of claim 6 , wherein
the circuit board is connected to a display panel on which a display image is displayed, the display panel having a control element placed thereon along the circuit board,
the control element includes a plurality of element conductors, a main-element-conductor group, which is a group of main element conductors, being included in the element conductors, and,
supply conductors of the circuit board that are connected to the main element conductors are main supply conductors, and that a group of the main supply conductors is a main-supply-conductor group, the ground portion is located at an isolation position avoiding the main-supply-conductor group.
8. The display of claim 7 , wherein the isolation position is a position in the circuit board along an outer edge of the circuit board.
9. The display of claim 7 , wherein
a sub-element-conductor group, which is a group of sub element conductors, is included in the plurality of element conductors, and,
supply conductors of the circuit board that are connected to the sub element conductors are sub supply conductors, that a group of the sub element conductors is a sub-supply-conductor group, and that a line along a shape of the circuit board which bends is a bend line, the isolation position is located on the bend line that overlaps the sub-supply-conductor group.
10. The display of claim 7 , wherein
at least part of the main supply conductors are located at a bending portion of the circuit board, and
the at least part of the main supply conductors that are located at the bending portion of the circuit board are shaped to fit the shape of the circuit board that bends.
11. An electronic device comprising the display of claim 6 .
