BACKGROUND OF THE INVENTION
Field of Invention
[0001] The present invention relates to a lamp technology, especially a lamp assembly and
an integrated junction box thereof.
Description of Related Art
[0002] For connecting to a power source, a junction box is usual design in the conventional
lamp assembly, wherein the lamp holder and the junction box are two separate components,
and wiring is necessary for electrically connecting both. The lamp holder and the
junction box are manufactured by different tooling moulds, and this arrangement has
drawbacks of redundant tooling moulds, high production cost, complicated assembly
process, and low yield rate. Further, this prior design has poor interchangeability,
since each type of the junction boxes is specified for one wiring type. Moreover,
the wiring is fixed on the junction box only with screws, which means a screw driver
becomes one key tool for connecting wiring. Therein, the wiring operation will be
impossible when no screw driver in hand, such that it is inconvenient for the wiring
connection.
SUMMARY OF THE INVENTION
[0003] In view of the above, the present invention provides a lamp assembly and an integrated
junction box thereof, to provide a solution for aforementioned redundant tooling mould,
high cost, complicated assembly process, and low yield rate in the prior art lamp
technology.
[0004] In view of the above purpose, the present invention provides an integrated junction
box, which includes a terminal receptacle and a lamp holder fixed to the terminal
receptacle. The terminal receptacle includes an outlet opening configured for passing
an external connecting wire through, and for the external connecting wire to electrically
connect the terminal receptacle. A cover has a rotatable connection with the terminal
receptacle, wherein a rotation of the cover to the terminal receptacle forms an open
status or a tight status between the outlet opening and the cover, for dis-attaching
the external connecting wire from the outlet opening in the open status, or fixing
the external connecting wire in the outlet opening in the tight status.
[0005] Besides, the terminal receptacle may include an enclosure, wherein the outlet opening
is disposed above a side wall of the enclosure, wherein a plugging plate is disposed
on the cover, to be inserted through and to engage a bottom wall of the enclosure.
[0006] Further, at least two gripping protrusions may be separately disposed on the plugging
plate along a direction of inserting the plugging plate through a plugging hole on
the bottom wall of the enclosure, for engaging the gripping protrusions.
[0007] In one embodiment, there are two plugging plates disposed on the cover in parallel,
and a count of the corresponding plugging holes in the enclosure is two.
[0008] Besides, a wire tying plate may be formed as downward protrusion on the cover, and
the wire tying plate includes a plurality of teeth facing a surface of the enclosure;
or, the wire tying plate is disposed on the enclosure with an upward protrusion, and
includes the plurality of teeth facing a surface of the cover; or, a first tying plate
is disposed on the cover and includes a plurality of first teeth facing the surface
of the enclosure, and a second wire tying plate is disposed on the enclosure to correspond
to the first tying plate, and the second tying plate includes a plurality of second
teeth for matching the first teeth.
[0009] Besides, the outlet opening may include a trapezoid slot on a side of the enclosure
facing the cover; the cover further includes a wire pressing plate with a trapezoid
shape to be inserted into the outlet opening.
[0010] In one embodiment, the enclosure further includes a first accommodating chamber and
a second accommodating chamber communicating with a side of the first accommodating
chamber. The outlet opening is disposed above a side wall of the second accommodating
chamber. The terminal receptacle further includes a terminal set disposed in the first
accommodating chamber, wherein the terminal set faces the outside of the integrated
junction box through the outlet opening, and the terminal set includes a wiring hole
for receiving and fixing the external connecting wire therein.
[0011] In one embodiment, the terminal set further includes a supporting plate and a terminal
assembly disposed on the supporting plate. The wiring hole is disposed in the terminal
assembly. A plurality of engaging plates are disposed on a bottom of the first accommodating
chamber, and the engaging plates comprise a plurality of engaging protrusions to engage
the supporting plate when the supporting plate is inserted between the engaging plates
from the outside of the first accommodating chamber.
[0012] In one embodiment, two connecting portions are disposed on an opposite side of the
enclosure to the outlet opening, and an extrusion is disposed on the cover to have
a rotating pin configured to be inserted into the two connecting portions, which respectively
have two plugging holes for fitting the rotating pin.
[0013] The present invention further provides a lamp assembly, which includes: a light source;
and the aforementioned integrated junction box, wherein the light source is disposed
on the aforementioned lamp holder.
[0014] With the embodiment, the benefits of the present invention: in the integrated junction
box, the cover is disposed on the terminal receptacle; the outlet opening is disposed
on the terminal receptacle, and the external connecting wire is directly through the
outlet opening to electrically connect to the terminal receptacle. When the cover
rotates to the tight status, the external connecting wire can be fixed; or, when the
cover rotates to the open status, the external connecting wire can be dis-attached.
Thus, in the present invention, the disposition of the cover can provide similar functions
to the prior junction box and the prior lamp holder. Moreover, the conduction wire
between the prior junction box and the prior lamp holder can be excluded, such that
higher reliability, less tooling mould(s), simpler production process, and higher
yield rate can be achieved. Besides, the step of dis-attaching or fixing of the external
connecting wire becomes much easier by merely rotating the cover in different directions
to the terminal receptacle.

[0022] With reference to Figs. 1 to 5, the present invention provides an integrated junction
box 100, which includes a terminal receptacle 1 and a lamp holder 40 fixed to the
terminal receptacle 1. The terminal receptacle 1 includes an outlet opening 12 configured
for passing an external connecting wire through, to directly and electrically connect
the terminal receptacle 1 with the external connecting wire. A cover 20 has a rotatable
connection with the terminal receptacle 1, wherein a rotation of the cover 20 to the
terminal receptacle 1 forms an open status (Fig. 3) or a tight status (Fig. 1) between
the outlet opening 12 and the cover 20. In the tight status, the cover 20 rotates
to form a tight space between the outlet opening 12 and the cover 20 for fixing the
external connecting wire in the outlet opening 12. In the open status, the cover 20
rotates to leave an open space above the outlet opening 12 available for dis-attaching
the external connecting wire from the outlet opening 12.
[0023] In the aforementioned embodiment, the cover 20 is disposed on the terminal receptacle
1. The outlet opening 12 is disposed above the terminal receptacle 1, and the external
connecting wire may directly pass through the outlet opening 12 to electrically connect
the terminal receptacle 1. When the cover 20 rotates to the tight status, this operation
can fix a portion of the external connecting wire in the outlet opening 12. When the
cover 20 opens up (rotates to the open status), it may dis-attach the external connecting
wire from the outlet opening 12. The disposition of the cover 20, can integrate the
terminal receptacle 1 and the lamp holder 40 into one piece structure. Thus other
conducting wires between the terminal receptacle 1 and the lamp holder 40 can be excluded,
such that higher reliability, less tooling mould(s), simpler production process, and
higher yield rate can be achieved. The cover 20 and the terminal receptacle 1 construct
an assembly capable of forming the open status or the tight status without other tools,
wherein a step of dis-attaching or fixing of the external connecting wire becomes
much easier by merely rotating the cover 20 to/off the terminal receptacle 1.
[0024] Besides, the terminal receptacle 1 may include an enclosure 10. The outlet opening
12 is disposed above a side wall of the enclosure 10. A plugging plate 21 is disposed
on the cover 20, to be inserted through and to engage a bottom wall of the enclosure
10. The cover 20, the enclosure 10, and the plugging plate 21 are substantially plastic
components, which have good insulation and elastic capabilities. The cover 20 can
engage the enclosure 10 with the elastic capability of the plugging plates 21, which
provides a convenience of closing and opening the cover 20. When closing the cover
20, a step of pressing downward the cover 20 can make the plugging plates 21 engage
the enclosure 10. When opening the cover 20, a step of pulling upward the cover 20
with an elastic deformation in the plugging plates 21 can dis-attach the plugging
plates 21 from the enclosure 10.
[0025] Further, at least two gripping protrusions 22 may be separately disposed on the plugging
plates 21 along a direction of inserting the plugging plate through a plugging hole
14 on the enclosure, wherein the plugging hole 14 is disposed on the bottom wall of
the enclosure 10, for engaging the gripping protrusions 22. Corresponding to various
inserting depth requirements of the plugging plates 21, different ones of the gripping
protrusions 22 on the plugging plate 21 can be used to engage the plugging holes 14;
thereby, the outlet opening 12 has an adjustable size. When the external connecting
wire is thinner, the plugging plates 21 can have deeper inserting depths and the outlet
opening 12 becomes smaller such that the external connecting wire can be fixed. Or,
when the external connecting wire is thicker, the plugging plates 21 can have shallower
inserting depths and the outlet opening 12 becomes bigger in correspondence with the
thicker external connecting wire. Therefore, the at least two gripping protrusions
22 can be used to adjust the inserting depths of the plugging plates 21, for adjusting
the size of the outlet opening 12 for fitting the sizes of the external connecting
wires, such that different sizes of the external connecting wires according to various
customer's requirements, can be used in the integrated junction box of the present
invention. By the size adjustment of the outlet opening 12, the different sizes of
the external connecting wires used in the integrated junction box can meet test requirements
with a pull force greater than 60N.
[0026] In one embodiment, the gripping protrusions 22 may be in a form of saw teeth.
[0027] In one embodiment, a count of the plugging plates on the cover is two, which are
disposed on the cover 20 in parallel, and a count of the corresponding plugging holes
on the enclosure 10 are two.
[0028] In one embodiment, a wire tying plate 24 may be formed as downward protrusion on
the cover 20, and the wire tying plate 24 includes a plurality of teeth 241 facing
a surface of the enclosure 10. Or, the wire tying plate is disposed on the enclosure
10 with an upward protrusion, and includes the plurality of teeth facing a surface
of the cover 20; or, a first tying plate is disposed on the cover 20 and includes
a plurality of first teeth facing the surface of the enclosure 10, and a second wire
tying plate is disposed on the enclosure 10 to correspond to the first tying plate,
and the second tying plate includes a plurality of second teeth corresponding to the
first teeth. In Fig. 3, a positioning plate 15 is disposed on the enclosure 10, wherein
the positioning plate 15 faces the wire tying plate 24. Thereby, a second positioning
function is built inward from the outlet opening 12, and it can provide a further
fixing function over the external connecting wires. The teeth 241 on the wire tying
plate 24, can increase friction between the wire tying plate 24 and the external connecting
wires, for securing that the electrical connection between the external connecting
wires and the terminal receptacle 1 is more reliable, to avoid the external connecting
wires from falling off. Or, in one embodiment, the wire tying plate 24 is disposed,
and the positioning plate 15 is excluded. Or, the wire tying plate 24 may be disposed
on the enclosure 10, and the teeth are disposed on the wire tying plate 24 to face
a surface of the cover 20. Alternatively, a first tying plate is disposed on the cover
20 and includes a plurality of first teeth facing the surface of the enclosure 10,
and a second wire tying plate is disposed on the enclosure 10 to correspond to the
first tying plate, and the second tying plate includes a plurality of second teeth
corresponding to the first teeth. The teeth on corresponding sides can make the fixing
of the external connecting wire more reliable.
[0029] Besides, the outlet opening 12 may include a trapezoid slot on a side of the enclosure
10 to face the cover 20. The cover 20 may further include a wire pressing plate 23
with a trapezoid shape to be inserted into the outlet opening 12. Corresponding to
various inserting depths of the plugging plates 21, the wire pressing plate 23 correspondingly
has different inserting depths into the outlet opening 12. Thereby, the outlet opening
12 may have adjustable sizes. By the aforementioned operation of the outlet opening
12 and the wire pressing plate 23, the size adjustment of the outlet opening 12 can
be further secured, for fixing various types of the external connecting wires.
[0030] The enclosure 10 is in a quasi-cylindrical shape. The enclosure 10 further includes
a first accommodating chamber 11 and a second accommodating chamber 13 communicating
with a side of the first accommodating chamber 11 (the second accommodating chamber
13 communicating the first accommodating chamber 11). The first accommodating chamber
11 is also in a quasi-cylindrical shape. The outlet opening 12 is disposed above a
side wall of the second accommodating chamber 13. The terminal receptacle 1 further
includes a terminal set 30 disposed in the first accommodating chamber 11, wherein
the terminal set 30 directly faces the outside of the integrated junction box 100
through the outlet opening 12, and the terminal set 30 includes a wiring hole 34 for
receiving and fixing the external connecting wire therein. Specifically, a terminal
clamp 35 is disposed on the terminal set 30, wherein when the external connecting
wire extends into the wiring hole 34, the external connecting wire can be clamped
and fixed by pressing the terminal clamp 35. The external connecting cable can be
released by pressing the terminal clamp 35 again.
[0031] The terminal set 30 further includes a supporting plate 31 in a rectangular shape
and a terminal assembly 32 disposed on the supporting plate 31. The wiring hole 34
is disposed in the terminal assembly 32. A plurality of engaging plates 17 are disposed
on a bottom of the first accommodating chamber 11, and the engaging plates 17 respectively
includes a plurality of engaging protrusions 171, each of which includes inward-inclined
ramp. When the supporting plate 31 is inserted between the engaging plates 17 by sliding
a plurality of edges of the supporting plate 31 along the ramps of the engaging plates
17, the inward-inclined ramps engage the supporting plate 31; thereby the terminal
set 30 is secured in the enclosure 10.
[0032] In one embodiment, two connecting portions 16 are disposed on an opposite side of
the enclosure 10 to the outlet opening 12, and an extrusion 25 is disposed on the
cover 20 with a rotating pin 26, which is configured to be inserted into the two connecting
portions 16, wherein the two connecting portions 16 respectively have two plugging
holes 161 for fitting the rotating pin 26. Therefore, the rotation connection between
the cover 20 and the enclosure 10 can be realized with the connection between the
rotating pin 26 and the plugging holes 161.
[0033] In one embodiment, a third accommodating chamber 18 (Fig. 5) is disposed on a back
of the enclosure 10 which is opposite to the first accommodating chamber 11. A lamp
holder 40 is partially inserted into and fixed in the third accommodating chamber
18. Specifically, a boss hole post 181 (Fig. 5) is disposed in the third accommodating
chamber 18, the lamp holder 40 includes an aligning hole 42 configured to be inserted
by the boss hole post 181. The lamp holder 40 may be fixed by a screw inserting into
the boss hole post 181. The lamp holder 40 is partially inserted into the third accommodating
chamber 18, to assembly the lamp holder 40 on the enclosure 10 to form a one piece
structure, such that the entire junction box becomes more compact. The communicating
hole 41 communicates the third accommodating chamber 18 and the first accommodating
chamber 11, such that the electrical connection between the lamp holder 40 and the
terminal set 30 can be realized by the terminal 33 without the prior conducting wire,
which makes the internal structure simpler.
[0034] Please refer to Fig. 6, wherein the present invention further provides a lamp assembly
200, which includes: a light source 60; and the integrated junction box 100, wherein
the light source 60 is disposed on the lamp holder 40 of the integrated junction box
100. With the one piece structure of the integrated junction box 100, the light source
60 is directly disposed on the lamp holder 40, such that higher reliability, less
tooling mould(s), simpler production process, and higher yield rate can be achieved.
Besides, wire connection can be done by merely rotating the cover 20to/off the terminal
receptacle 1.
[0035] With reference to Fig. 7, the integrated junction box 100 may further include a controlling
component 50. According to the present invention, the controlling component 50 includes
at least one of a dimmer controller, a proximity sensor, a timer, a wireless controller,
and an ambient light sensor.
[0036] For example, when the controlling component 50 includes the dimmer controller, which
may control a brightness of the light source 60. Further, when the controlling component
50 includes the dimmer controller and the proximity sensor, the controlling component
50 may control the brightness of the light source 60, according to an object sensing
result obtained by the proximity sensor. When the object is approaching to the integrated
junction box 100, the brightness of the light source 60 is controller to be higher.
When the object is leaving from the integrated junction box 100, the brightness of
the light source 60 is controller to be lower.
[0037] In one embodiment, when the controlling component 50 includes the proximity sensor
but no dimmer controller, the controlling component 50 can sense the approaching object
to determine to turning on the light source disposed on the integrated junction box.
[0038] In one embodiment, when the controlling component 50 includes the timer, the controlling
component 50 can control the light source 60 to turn off after a time period of turning
on the light source 60. In one embodiment, the time period can be since turning on
the light source 60 by sensing the approaching object.
[0039] In one embodiment, when the controlling component 50 includes the wireless controller,
the controlling component 50 can receive a wireless signal to determine to turning
on the light source 60.
[0040] In one embodiment, when the controlling component 50 includes the ambient light sensor,
