Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to a sensor, and particularly
to a sensor having a separate antenna.
2. Description of the Related Art
[0002] A conventional sensor senses changes of the environmental
condition, and provides a control signal according to the changes
of the environmental condition. The conventional sensor may
transmit the control signal to a device to control the device. For
example, a sensor of a lamp may sense changes of luminance of the
environmental light or a motion of an object.
[0003] When the luminance of the environmental light is changed or
someone or something is moving within a detection range of the
sensor, the sensor of the lamp may sense the changes of the
environmental light, and the sensor of the lamp may transmit the
control signal to the lamp to control the lamp. For example, when
the sensor senses that the luminance of the environment becomes
darker, the sensor controls the lamp to be brightened. When the
sensor senses that someone or something is moving, the sensor
controls the lamp to be turned on. When the sensor senses that
someone or something remains unmoving for a preset time period, the
sensor controls the lamp to be turned off Therefore, the light may
be automatically controlled.
[0004] The sensor may comprise control buttons to adjust range of
light change or to adjust delay time of the lamp. For example, when
the sensor senses that the luminance of the environmental light
becomes darker, the sensor controls the lamp to increase or
decrease brightness according to the range of the light change.
When the sensor senses that someone or something is moving, the
sensor controls the lamp to be turned on after the delay time of
the light. When the sensor senses that someone or something remains
unmoving for a preset time period, the sensor controls the light to
be turned off after the delay time of the light. Therefore,
misjudgment of the sensor may be avoided.
[0005] Further, the sensor may be remotely controlled by a remote
controller. The remote controller communicates with the sensor
through wireless communication technology, and the sensor may
comprise an antenna to transmit or receive wireless signals through
the wireless communication technology.
[0006] With reference to FIG. 6, the antenna 30 of the sensor is
welded on a circuit board 40 of the sensor, or the antenna 30 may
be a metal layer on the circuit board 40.
[0007] When the sensor is mounted in a ceiling or a wall of a
building, since the antenna 30 is mounted on the circuit board 40
and the circuit board 40 may be mounted in a shell of the sensor,
the antenna 30 may be embedded into the ceiling or the wall. Then,
the circuit board 40 may not be damaged by external damage or
sprinkled by water. When the circuit board is sprinkled by water,
short circuit may occur and damage the circuit board. However,
since the antenna 30 is embedded into the ceiling or the wall, the
ceiling or the wall may block wireless signals of wireless
communication of the antenna 30. Then, the antenna 30 may not
clearly transmit or receive the wireless signals, and quality of
the wireless communication of the antenna may be deteriorated.
Therefore, the conventional sensor needs to be improved.
SUMMARY OF THE INVENTION
[0008] An objective of the present invention is to provide a sensor
having a separate antenna to clearly transmit or receive wireless
signals.
[0009] To achieve the foregoing objective, the sensor comprises a
shell, a circuit board, a nameplate, an antenna, and a connecting
unit.
[0010] The shell comprises a substrate and a tubular wall. The
substrate comprises a first surface and a second surface, and the
first surface is opposite the second surface. The tubular wall is
mounted on the first surface of the substrate, and a containing
space is formed within an inner surface of the tubular wall and the
first surface of the substrate.
[0011] The circuit board is mounted in the containing space of the
shell.
[0012] The nameplate is mounted on the second surface of the
substrate of the shell.
[0013] The antenna is mounted on the nameplate and is separate from
the circuit board.
[0014] The connecting unit is electrically connected between the
antenna and the circuit board, and the connecting unit is mounted
through the substrate of the shell.
[0015] Since the antenna is mounted on the nameplate and
electrically connected to the circuit board through the connecting
unit, the antenna may be mounted outside of the containing space of
the shell. When the sensor is mounted on a ceiling or a wall of a
building, the ceiling or the wall may not block wireless signals of
wireless communication of the antenna, and the antenna may clearly
transmit or receive the wireless signals. Therefore, quality of the
wireless communication of the antenna may be increased.
[0016] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0023] With reference to FIGS. 1 and 2, an embodiment of the
present invention is a sensor 10 having a separate antenna. The
sensor 10 comprises a shell 11, a circuit board 12, a nameplate 13,
an antenna 131, and a connecting unit 14.
[0024] With reference to FIG. 3, the shell 11 comprises a substrate
111 and a tubular wall 112. The substrate 111 comprises a first
surface 1111 and a second surface 1112. The first surface 1111 is
opposite the second surface 1112. The tubular wall 112 is mounted
on the first surface 1111 of the substrate 111, and a containing
space 113 is formed within an inner surface 1121 of the tubular
wall 112 and the first surface 1111 of the substrate 111.
[0025] The circuit board 12 is mounted in the containing space 113
of the shell 11. As shown in FIGS. 1 and 2, the nameplate 13 is
mounted on the second surface 1112 of the substrate 111 of the
shell 11. The antenna 131 is mounted on the nameplate 13 and is
separate from the circuit board 12.
[0026] The connecting unit 14 is electrically connected between the
antenna 131 and the circuit board 12, and the connecting unit 14 is
mounted through the substrate 111 of the shell 11. In the
embodiment, the antenna 131 mounted on the nameplate 13 is mounted
on a surface of the nameplate 13 which is opposite to the substrate
111 of the shell 11.
[0027] With reference to FIG. 4, since the antenna 131 is mounted
on the nameplate 13 and electrically connected to the circuit board
12 through the connecting unit 14, the antenna 131 may be mounted
outside of the containing space 113 of the shell 11. The antenna
131 is mounted on the nameplate 13, and the nameplate 13 is mounted
on the second surface 1112 of the substrate 111 of the shell 11.
When the sensor 10 is mounted on a ceiling or a wall of a building,
the ceiling or the wall may not block wireless signals of wireless
communication of the antenna 131, and the antenna 131 may clearly
transmit or receive the wireless signals. Therefore, quality of the
wireless communication of the antenna 131 may be improved. In the
embodiment, the sensor 10 is an embedded sensor.
[0028] In the embodiment, the substrate 111 has at least one
through hole 1113, and the at least one through hole 1113 is formed
through the first surface 1111 and the second surface 1112 of the
substrate 111. The connecting unit 14 is mounted through the at
least one through hole 1113. The second surface 1112 of the
substrate 111 has a notch 1114, and the nameplate 13 is mounted in
the notch 1114 of the second surface 1112 of the substrate 111.
[0029] The antenna 131 is a metal layer on the nameplate 13.
[0030] With reference to FIG. 4, the sensor 10 is mounted on a
ceiling 20 or a wall of a building. In the embodiment, an exterior
surface 1122 of the tubular wall 112 of the shell 11 forms external
threads, and the sensor 10 may be screwed into the ceiling 20 or
the wall of the building to be fixed on the ceiling 20 or the wall
of the building. In the embodiment, the connecting unit 14 may be
an electric wire, as shown in FIG. 4, or may be a contact spring,
as shown in FIG. 5.
[0031] With reference to FIGS. 2 and 3, the sensor 10 further
comprises a cover 15. The cover 15 is mounted on the second surface
1112 of the substrate 111 and covers the nameplate 13. Therefore,
the cover 15 may protect the nameplate 13, and dust may not enter
the sensor 10 to affect the circuit board 12.
[0032] The substrate 111 further comprises a first annular wall
1115 and an annular engaging portion 1116. The first annular wall
1115 axially extends from the second surface 1112 of the substrate
111 along an edge of the notch 1114. The annular engaging portion
1116 radially extends from an end of the first annular wall 1115,
and the annular engaging portion 1116 comprises at least one gap
1117.
[0033] The cover 15 comprises a plate 151, a second annular wall
152, and at least one protrusion 153. The second annular wall 152
of the cover 15 is mounted on an edge of the plate 151 of the cover
15. The at least one protrusion 153 of the cover 15 is formed on an
inner surface of the second annular wall 152 of the cover 15.
[0034] When the cover 15 is mounted on the second surface 1112 of
the substrate 111, the at least one protrusion 153 of the cover 15
is aimed at the at least one gap 1117 of the annular engaging
portion 1116 of the substrate 111 of the shell 11, and then the
cover 15 is mounted on the second surface 1112 of the substrate 111
and is rotated. Therefore, the at least one protrusion 153 of the
cover 15 may be engaged with the annular engaging portion 1116 of
the substrate 111 of the shell 11, and the cover 15 may be firmly
mounted on the shell 11.
[0035] Further, the antenna 131 mounted on the nameplate 13 is
mounted on the surface of the nameplate 13 which is opposite to the
substrate 111 of the shell 11. When the sensor 10 is a sensor of a
lamp, the sensor 10 may transmit sensing signals to sense whether
someone or something is moving within a detection range of the
sensor. Since the sensor 10 extends out of a surface of the lamp,
the sensing signals transmitted by the antenna 131 may not block by
the lamp, and the sensor 10 may clearly sense whether someone or
something is moving within the detection range.
[0036] Even though numerous characteristics and advantages of the
present invention have been set forth in the foregoing description,
together with details of the structure and function of the
invention, the disclosure is illustrative only. Changes may be made
in detail, especially in matters of shape, size, and arrangement of
parts within the principles of the invention to the full extent
indicated by the broad general meaning of the terms in which the
appended claims are expressed.
