Abstract

A housing structure of a printed circuit board with a connector includes the printed circuit board on which an electronic component is implemented, the connector implemented on an end portion of the printed circuit board, the connector including a fitted portion fitted with a mating component which is a connection target, and a housing accommodating the printed circuit board and the connector. The housing includes a first case surrounding the printed circuit board and a second case covering the connector. The second case includes a first surface portion arranged at a side where the fitted portion of the connector is provided, and at least one second surface portion which is nonparallel to the first surface portion.

First claim

The invention claimed is:

1. A housing structure of a printed circuit board with a connector, comprising:
the printed circuit board on which an electronic component is implemented;
the connector implemented on an end portion of the printed circuit board, the connector including a fitted portion fitted with a mating component which is a connection target; and
a housing accommodating the printed circuit board and the connector, wherein
the housing includes a first case surrounding the printed circuit board and a second case covering the connector, and
the second case includes a first surface portion arranged at a side where the fitted portion of the connector is provided, and at least one second surface portion which is nonparallel to the first surface portion,
wherein one of the first surface portion and the at least one second surface portion of the second case:
is opposed to the printed circuit board, and
is arranged at a position away from the printed circuit board relative to a surface of the first case, the surface which is arranged at a side where the one of the first surface portion and the at least one second surface portion of the second case is provided relative to the printed circuit board and which is opposed to the printed circuit board;

wherein the one of the first surface portion and the at least one second surface portion of the second case serving as the surface of the second case opposed to the printed circuit board includes:
a flat surface portion which is in parallel to a surface of the printed circuit board on which the electronic component is implemented, and
an extending portion continuously provided from an end portion of the flat surface portion, the end portion arranged close to the first case, the extending portion extending toward the printed circuit board; and

wherein the first case includes:
a bottom plate portion covering a lower surface of the printed circuit board,
a side wall portion which is standingly provided from the bottom plate portion to cover a side portion of the printed circuit board other than a side of the printed circuit board where the connector is implemented, and
a top plate portion covering a part of an upper surface of the printed circuit board, the upper surface which is arranged at a side where the flat surface portion is provided, the part of the upper surface where the connector is inhibited from being arranged, wherein the connector is oriented such that the mating component is fitted in parallel to the printed circuit board from a distal end side of the fitted portion,
the second case is configured such that the first surface portion is formed with an opening surrounding the fitted portion, the flat surface portion of the second surface portion being oriented to be opposed to the printed circuit board in a parallel manner while sandwiching the connector therebetween, the extending portion extending perpendicularly to the flat surface portion toward the printed circuit board and being in contact with an end portion of the top plate portion,
one of the first case and the second case includes an engaged portion, the other of the first case and the second case including a hook portion engaging with the engaged portion, the engaged portion and the hook portion constituting a snap fit portion, and
the fitted portion extends outwardly from the first surface portion.

2. A housing structure of a printed circuit board with a connector, comprising:
the printed circuit board on which an electronic component is implemented;
the connector implemented on an end portion of the printed circuit board, the connector including a fitted portion fitted with a mating component which is a connection target; and
a housing accommodating the printed circuit board and the connector, wherein
the housing includes a first case surrounding the printed circuit board and a second case covering the connector, and
the second case includes a first surface portion arranged at a side where the fitted portion of the connector is provided, and at least one second surface portion which is nonparallel to the first surface portion,
wherein one of the first surface portion and the at least one second surface portion of the second case:
is opposed to the printed circuit board, and
is arranged at a position away from the printed circuit board relative to a surface of the first case, the surface which is arranged at a side where the one of the first surface portion and the at least one second surface portion of the second case is provided relative to the printed circuit board and which is opposed to the printed circuit board;

wherein the one of the first surface portion and the at least one second surface portion of the second case serving as the surface of the second case opposed to the printed circuit board includes:
a flat surface portion which is in parallel to a surface of the printed circuit board on which the electronic component is implemented and has a portion arranged at a side of the first case, and
an extending portion continuously provided from the portion of the flat surface portion, the extending portion extending toward the printed circuit board,

wherein the first case includes:
a bottom plate portion covering a lower surface of the printed circuit board,
a side wall portion which is standingly provided from the bottom plate portion to cover a side portion of the printed circuit board other than a side of the printed circuit board where the connector is implemented, and
a top plate portion covering a part of an upper surface of the printed circuit board, the upper surface which is arranged at a side where the flat surface portion is provided, the part of
the upper surface where the connector is inhibited from being arranged, wherein the connector is oriented such that the mating component is fitted in parallel to the printed
circuit board from a distal end side of the fitted portion,
the second case is configured such that the first surface portion is formed with an opening
surrounding the fitted portion, the flat surface portion of the second surface portion being oriented to be opposed to the printed circuit board in a parallel manner while sandwiching the connector therebetween, the extending portion extending perpendicularly to the flat surface portion toward the printed circuit board and being in contact with an end portion of the top plate portion,
one of the first case and the second case includes an engaged portion, the other of the first case and the second case including a hook portion engaging with the engaged portion, the engaged portion and the hook portion constituting a snap fit portion, and
the fitted portion extends outwardly from the first surface portion.
