ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a cluster assembly of a compressor, and more particularly, to a holder for lead wire of a cluster assembly which has a simple structure and is less costly than prior devices.
2. Description of the Prior Art
FIG. 1
is a partial sectional view showing a compressor with a conventional cluster assembly disposed. In general, a compressor has a structure in which an electrical driving unit
20
and a compression unit (not shown) are disposed inside a sealed case
10
comprising an upper case
11
and a lower case
12
as shown in FIG.
1
.
The electrical driving unit
20
powers the compression unit by receiving power from outside. The unit
20
comprises a cylinder block
21
fixed in the lower case
12
, a stator
22
fixed on the upper part of the cylinder block
21
and a rotor
23
rotatably disposed inside the stator
22
.
Disposed on one side of the lower case
12
are a terminal
30
for supplying external power to the electrical driving unit
20
and a set of terminal pins
31
for providing connection to the external power. The terminal
30
has a cluster assembly
40
connected for transmitting the external power to the electrical driving unit
20
.
As shown in
FIG. 2
, this cluster assembly
40
has a structure in which three lead wires
42
a
,
43
a
,
44
a
are each connected to the electrical driving unit
20
and are connected to a box shaped cluster housing
41
having pin holes
45
a
,
46
a
,
47
a
for receiving the terminal pin
31
.
The cluster housing
41
has three channels
45
,
46
,
47
for receiving contactors
42
b
,
43
b
,
44
b
. Each channel
45
,
46
,
47
has pin holes
45
a
,
46
a
,
47
a
formed to receive the terminal pins
31
. The lead wires
42
a
,
43
a
,
44
a
connected to the electrical driving unit
20
are inserted one by one into the channels
45
,
46
,
47
and fixed to the contactors
42
b
,
43
b
,
44
b.
Each lead wire
42
a
,
43
a
,
44
a
is covered with an insulating tube
42
c
,
43
c
,
44
c
for electrical insulation. In addition, these lead wires
42
a
,
43
a
,
44
a
are held together by a holding tube
50
to prevent a short circuit from occurring by contact with other parts inside the sealed case
10
if the lead wires
42
a
,
43
a
,
44
a
are separated from each other.
However, the above conventional holding tube
50
is woven fabric which requires heat processing on both cut ends. Moreover, it is difficult to insert lead wires
42
a
,
43
a
,
44
a
into the tube
50
because it is not hard. Therefore, the conventional holding tube is costly and difficult to work with.
SUMMARY OF THE INVENTION
An object of the invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages described hereinafter.
Accordingly, a specific object of the present invention is to solve the foregoing problems by providing a holder for lead wires that is easily produced by punching process, and is less costly and easy to work with.
The foregoing and other objects and advantages are realized by providing a holding member for holding a plurality of lead wires together comprising one or more holding plate, each plate having a hole for receiving the plurality of lead wires all together and a slit extending from the hole to the outer edge of the holding plate.
In the present invention having the above structure, it is preferable that the holding plates are bendably connected side by side.
The slits of the holding plates are formed on a same side parallel to a connecting portion between the holding plates, or alternatively on an opposite side parallel to the connecting portion.
It is preferable that the holding plate is made of polyester.
