CA 02418873 2003-02-13
In above two embodiments, when the connector 4 is embedded
into the connecting holes 21 and 21'. The braking pieces 26 and 26'
pass through the braking inclined surface 26 of the connector 4 so
that the braking pieces 33, 33' are buckled to a bottom of the braking
inclined surface 42. At the same time, the conductive head 41 is
exactly embedded into the conductive seats 31, 31' of the receptacles
3, 3' so as to supply power to the lamp through the lamp rod 5.
Moreover, the connector 4 is firmly secured to the lamp rod 5.
Referring to Figs. IA to IF, the positioning screws 33, 33' are
protruded from the wall of the connecting holes 21, 21' of the
retaining seats 2, 2', or the positioning studs 23, 23' are protruded
from the braking pieces 26, 26'.
Referring to Figs. 1 , 3 , I A to 1 C, and 6, if the wire connecting
box I is positioned at a position shown in Fig. 6, then the positioning
screws 33, 33' are protruded from the walls of the connecting holes
21, 21'. The stop edge 441 at the front end of the via hole 44 of the
connector 4 is removed, then the connector 4 is embedded into the
connecting holes 21, 21'. The positioning screws 33, 33' slide
through the channel 43 so that the conductive head 41 of the
connector 4 is embedded into the conductive seats 31, 31' of the
receptacles 3, 3'. Further, the braking pieces 26, 26' are exactly
embedded into a bottom of the braking inclined surface 42 of the
connector 4.
The stop edge 441 of the via hole 44 of the connector 4 exists,
and the stop wall 431 of the channel 43 is removed in advance. The
connector 4 embedded into the connecting holes 21, 21' will be
stopped by the p'ositioning screws 33, 33' so that it can not be
inserted further and thus the connector 4 will not enter into the
connecting holes 21, 21' of the retaining seats 2, 2' of the wire
connecting box 1' (referring to Fig. 6) at another stage.
Referring to Fig. 1, I D to IF, 3 and 6, in this stage, as shown in

the connecting holes 21, 21'. "The positioning studs 23, 23' will
pass through the channel 43 without being hindered by the stop wall
431 so that the conductive head 41 of the connector 4 is embedded
into the conductive seats 31, 31' of' the receptacles 3, 3' for
conduction. Moreover, the braking pieces 26, 26' exactly slide into
the bottom of the braking inclined surface 42 of the connector 4 so as
to be positioned therein. If it is desired to embed the connector 4
into the wire connecting box 1(referring to Fig. 6), it will be
hindered by the screws 33, 33' so that it is stopped. Thereby, the
connector 4 will not enter into the connecting holes 21, 21' of the
retaining seats 2, 2' of the wire connecting box 1(referring to Fig.
6).
As described above, when the stop wall 431 of the channel 43
of the connector 4 exists, the stop edge 441 at the front end of the via
hole 44 is removed in advance. Then, the connector 4 is embedded
into the connecting holes 21, 21'. It will be hindered by the
positioning studs 23, 23'. Thereby, the connector 4 will not enter
into the connecting holes 21, 21' of the retaining seats 2, 2' of the
wire connecting box 1(referring to Fig. 6).
By above structure, the connector 4 can be correctly aligned to
the wire connecting boxes 1, 1' so as to avoid the carelessness in
assembly. Thereby, the present invention can be assembled and
packaged rapidly with less material.
