BACKGROUND OF THE INVENTION
1. Field of the invention
[0001] The present invention is related to an end connecting structure for fitting light,
and especially to definite and reliable connecting of male or female electrical connecting
insertion ends of a fitting light with the internal conductors of a lamp pipe, thus
safety standard with high criticality can be met and elevated.
2. Description of the Prior Art
[0002] A fitting light or lighting rope system comprises mainly lamp strings having light
emitting or flashing function in a flexible and transparent pipe. It is advantageous
in providing a unique decorative effect by light emitting and flashing of a lot of
lamp bulbs through a transparent pipe. With the flexible structure which is plastic,
the fitting light can be used in various fields for decoration with various patterns.
For example, it can be hung on a surface of a building, or can be wrapped on a broad
wall with a given pattern to form a marvelous and attractive large light emitting
or flashing pattern.
[0003] In using such a fitting light, it can have any of various decorative patterns in
pursuance of designed patterns or requirement of customers. Hence in manufacturing
in factories, fitting lights are all in rolled form. A user buying a fitting light
in rolled form can make cutting according to indicative marks to obtain desired lengths
and then the lengths are taken for connection.
[0004] Fig. 1 shows a kind of internal structure of such a conventional fitting light 10
which is shaped to form a transparent inner pipe 11 of suitable diameter firstly in
a factory, the transparent inner pipe 11 is shaped and synchronically makes positioning
of two conductors 12, 13 mutually separated in the interior of the transparent inner
pipe 11 itself. The conductors 12, 13 are comprised both of a plurality of core wires.
[0005] The transparent inner pipe 11 is provided on the periphery thereof with two oppositely
arranged guiding grooves 14, 15; and a plurality of diametrical holes 16, 17 of smaller
and larger diameters respectively are provided along the transparent inner pipe 11.
A plurality of miniature lamp bulbs 18 can be placed in the diametrical holes 17 of
larger diameters, two pins 181, 182 of each miniature lamp bulb 18 can be placed in
the diametrical holes 16 of smaller diameters, and then are processed (such as by
welding) to connect and complete a desired internal lamp string. The core wires of
the ends of the conductors 12, 13 can be extended outwardly to electrically connect
with the lamp string to get an electric conducting state. The necessitate transparent
inner pipe 11 of such a combination can be further enveloped with another transparent
external layer 100 by ejection molding to complete the entire fitting light.
[0006] A connecting member 19 is provided with and makes positioning of two metallic insertion
pieces 191, 192 integrally formed therewith by molding and mutually separated in alignment
with the two conductors 12, 13. These metallic insertion pieces 191, 192 are provided
respectively with insertion ends 193, 194 on one side of the connecting member 19,
and are provided correspondingly with a pair of male or female electrical connecting
ends 195, 196 on the other side of the connecting member 19. In this conventional
technique structure, the insertion ends 193, 194 on the connecting member 19 are in
alignment with and accept insertion of the two conductors 12, 13 with the core wires
to build electrical connecting. When the male or female electrical connecting ends
195, 196 are electrically connected, the internal lamp string is wholly lightened
and flashes.
[0007] The conventional connecting structure for the ends of conductors of a fitting light
has its disadvantage residing in that, when a roll of fitting light is cut to get
a required length, a worker or a consumer does the work of alignment for connecting
of the insertion ends 193, 194 on the connecting member 19 with the two conductors
12, 13 with manpower, assembling is slow and inconvenient. And the insertion ends
193, 194 are often unable to accurately insert respectively into the conductors 12,
13 concentrically, sometimes, deviation in insertion may result incomplete connecting
or may result breakage of some thin wall areas 121, 131 of the transparent inner pipe
due to extruding. Such connecting structure for the ends of conductors of a fitting
light may result undesired and unexpected electrical conducting state. A long and
distantly connected fitting light may come into a danger state with overly high electric
resistance or abnormal temperature raising by long period electrical conducting, and
thereby is uneasy to meet the severer requirement of safety standard.
SUMMARY OF THE INVENTION
[0008] The object of the present invention is to provide an end connecting structure for
fitting light. When the transparent inner pipe of the fitting light is formed, the
conductors simultaneously positioned in the pipe can be processed to leave a desired
length each. While the male or female electrical connecting ends can be formed by
pressing or turning in mating with the above stated conductors with desired lengths
in advance, thus the male or female electrical connecting ends are provided each with
a connecting section for connecting with the conductors prepared. Thereby, the male
or female electrical connecting ends of the fitting light can be stably and firmly
connected with the conductors in the fitting light by pressing of clamping method.
And the quality and reliability of electrical connection of them can be assured to
meet the severe requirement of safety standard.
[0009] The present invention will be apparent in its novelty and features after reading
the detailed description of the preferred embodiment thereof in reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] Referring to Fig. 2, in the fitting light 20 shown in the drawing, there are a transparent
inner pipe 21 and an enveloping transparent external layer 22 made by ejection molding.
The transparent inner pipe 21 is structurally the same as that of the above stated
conventional fitting light. In the present invention, when the fitting light 20 is
cut to get a desired length, the conductor sections 24, 25 with desired lengths are
provided on one end or both ends 23 in advance. These conductor sections 24, 25 with
desired lengths are by all means formed from extending of the conductors formed and
positioned inside of the transparent inner pipe 21.
[0012] Male electrical connecting ends (or female electrical connecting ends) 30 are provided
each on one end thereof with a connecting section 31 for connecting with the conductor
sections 24, 25. Thereby, the conductor sections 24, 25 can be integrally connected
therewith by pressing or clamping method with a machine or a simple tool (such as
a pair of pincers).
[0013] As shown in Fig. 2 and Figs. 3A and 3B, The connecting sections 31 of the male or
female electrical connecting ends 30 can be formed each into a U shaped cross-section
by pressing process in advance. So that when the conductor sections 24, 25 are placed
in the connecting sections 31, they can be subsequentially pressed together on a lathe,
or can be clamped together with a simple tool by a consumer. In addition to the above
stated pressing process in processing the male or female electrical connecting ends
30, in another embodiment shown in Fig. 3C, the male or female electrical connecting
ends 30 can also be turned to get an inner hole 32 with a suitable depth from solid
