As a result, thecommunication lines 7 are sandwiched between theholding portions 12 a and 12 b of thefixing base 11 and the receivingportions 25 a and 25 b of thereceiver 20. - Subsequently, the plurality of communication lines 7 (the case of the
communication lines FIG. 4 ) are placed on thereceiving portions 25 a and 25 b of thereceiver 20. Then, thepresser 30 is fitted between thesandwiching portions 24 a to 24 c from above thereceiver 20 so that thecommunication lines 7 are sandwiched between thereceiving portions 25 a and 25 b of thereceiver 20 and thepressing portions presser 30. - Finally,
screws 35, which are fixing member, are inserted through thescrew insertion holes presser 30, thereceiver 20, and thefixing base 11, screwed intonuts 36 disposed on the rear faces of thefixing portions 13 a to 13 c of thefixing base 11 and integrally fixed. The case in which thescrew 35 is screwed into thenut 36 disposed on the rear face of thefixing base 11 is shown, but the nut may be omitted and thescrew insertion hole 14 of thefixing base 11 is used as a screw hole, through which thescrew 35 may be screwed into. - As a result, the plurality of indoor/
outdoor communication lines 7 are bundled by the communication-line fixture 10 and fixed to the main body of theoutdoor unit 1. - Also, if each of the
communication lines 7 is to be removed for maintenance or the like, the communication line can be easily taken out by loosening thescrew 35 of the communication-line fixture 10 and by removing thepresser 30 or thepresser 30 and thereceiver 20. - According to the present embodiment, since the plurality of indoor/
outdoor communication lines 7 having one ends connected to the indoor units and the other ends to theterminal blocks 6 of the outdoor unit are stacked in double by the communication-line fixture 10 and fixed to the main body of theoutdoor unit 1 collectively, the large number ofcommunication lines 7 can be easily fixed even in a small space, and assembling performances and serviceability can be improved. -
FIG. 6 is an explanatory diagram of a fixing structure for an indoor/outdoor communication line of an air conditioner according toEmbodiment 2 of the present invention,FIG. 7 is an explanatory diagram illustrating a state in which a plurality of indoor/outdoor communication lines are fixed in a bundle by a communication-line fixture inFIG. 6 , andFIG. 8 is an exploded perspective view of the communication-line fixture inFIG. 7 . The same reference numerals are given to the same portions as those inEmbodiment 1. - The communication-
line fixture 10 according to this embodiment is formed by afixing base 40, a plurality ofpressers 50, and areceiver 60. - The
fixing base 40 has amain body portion 41 having a substantially U-shaped section, in which free ends of both-side plates are folded outward and provided withmounting pieces 43 a and 43 b having screw insertion holes 44 a and 44 b, and receivingportions 42 a and 42 b for the first andsecond communication lines 7 are disposed on the top face. In the center part in the width direction on the top face,screw insertion holes 45 a and 45 b are disposed vertically, and the twoscrew insertion holes 45 a and 45 b are arranged side by side between thereceiving portions 42 a and 42 b. In the vicinity of the four corners on the top face, respectivescrew insertion holes 46 are disposed. - Each of the
pressers 50 is formed having a length substantially half of that of the length of thefixing base 40 and the width smaller than the width of themain body portion 41. A projection-shaped pressing portion 51 is disposed corresponding to the one receiving portions 42 a (or 42 b) of the fixingbase 40, and the both end portions of the pressing portion 51 are folded downward and then folded outward, and mounting pieced 52 a and 52 b in which screw insertion holes 53 are disposed are provided. Thepressers 50 in the same structure are used in plural (the case of four pressers is shown in the figure). - The
receiver 60 has amain body portion 61 having a substantially U-shaped section formed having the length substantially equal to the length of the fixingbase 40 and the width formed slightly larger than the width of thepresser 50, fixing pieces 63 a to 63 c extended downward from both end portions and the center part in the longitudinal direction of the both side walls of themain body portion 61 and then, folded outward are disposed, and screw insertion holes 64 corresponding to the screw insertion holes 46 of the fixingbase 40 are disposed in the fixingpieces 63 a and 63 b on the both end portions. - Receiving
portions second communication lines 7 are disposed on the top face, and screw insertion holes 65 a and 65 b are disposed at positions corresponding to the screw insertion holes 45 a and 45 b of the fixingbase 40 at the center part in the width direction of the top face. - Subsequently, a procedure to fix the plurality of indoor/
outdoor communication lines 7 by the communication-line fixture 10 configured as above in a bundle will be described referring toFIGS. 7 and 9 . - First, the mounting
pieces 43 a and 43 b of the fixingbase 10 are brought into contact with the predetermined positions on the main body (thepartition plate 9 in this case) of theoutdoor unit 1, the screw inserted through the screw insertion holes 44 a and 44 b are screwed into thepartition plate 9, and the fixingbase 10 is fixed. - Then, one or two
communication lines 7 are placed on the one receiving portion 42 a (or 42 b) of the fixingbase 40, the top thereof is covered by thepresser 50 a, the mountingpieces base 40, and the screw inserted through the screw insertion holes 53 of the mountingpieces communication lines 7 are sandwiched between the fixingbase 40 and thepresser 50 a and fixed. - Similarly, the
communication lines 7 are placed on the other receivingportion 42 b of the fixingbase 40, sandwiched between thepresser 50 b and the fixingbase 40 and fixed (thepressers - Subsequently, the
receiver 60 is fitted with the bothpressers base 40. Then, the screws inserted through the screw holes 64 disposed in the fixingpieces 63 a and 63 b are inserted through the screw insertion holes 46 of the fixingbase 40 and screwed into the nuts disposed on the rear face and fixed. - Subsequently, the
communication lines 7 are placed on the one receivingportion 62 a (or 62 b) on the top face of thereceiver 60 and sandwiched and fixed by thepresser 50 c in the same way as the above. Also, in the same way, thecommunication lines 7 placed on the other receivingportion 62 b are sandwiched by thepresser 50 d and fixed (thepressers communication lines 7 are fixed by the communication-line fixture 10 collectively. In the above description, the case in which the screws are inserted through the screw insertion holes 45 a, 45 b, and 46 disposed in the fixingbase 40 and the screw insertion holes 65 a and 65 b disposed in thereceiver 60 by disposing the nuts on the rear face side is shown, but the nuts may be omitted and screw holes are disposed instead of the screw insertion holes 45 a, 45 b, 46, 65 a, and 65 b so that the screws are inserted into the screw holes. - In this embodiment, too, substantially the same effects as those in
Embodiment 1 can be obtained, but moreover, since the plurality of small-sized pressers 50 are disposed so as to fix thecommunication lines 7, thepressers 50 can be used as appropriate in accordance with the number of thecommunication lines 7 to be fixed, and in maintenance or the like, it is only necessary to remove only thepressers 50 or thepressers 50 and thereceiver 60 of the targetedcommunication lines 7, and the operation is easy. -
