Embodiment 1）

[0044] The compressor of Example 1 is a variable-capacity swash-plate compressor. Such as figure 1 as well as figure 2 As shown, this compressor includes a drive shaft 1 that is rotationally driven from the outside, and a casing 3 that supports the drive shaft 1 and enables the drive shaft 1 to rotate. In this compressor, a casing 3 is constituted by a front casing 3a, a cylinder block 3b, and a rear casing 3c. Such as image 3 As shown, a well-known swash plate type compression mechanism 5 that compresses the refrigerant based on the rotation of the drive shaft 1 is built in the housing 3 .

[0045] That is, a crank chamber 3d is formed in the front housing 3a, and a swash plate 5a that rotates together with the drive shaft 1 is provided in the crank chamber 3d. A plurality of cylinders 5b are formed in the cylinder 3b, and the piston 5c reciprocates in each of the cylinders 5b in accordance with the inclination angle of the swash plate 5a. A valve unit (not shown) is p...

Embodiment 2）

[0069] Such as Figure 7 As shown, the bracket 21 of the compressor of Example 2 does not have the convex part 117d. The length of the holding chamber 117a from the lower end side surface 117h to the upper end side 117i is slightly smaller than the diameter of the lead wire 9b. Other structures are the same as in Embodiment 1.

[0070] Compared with the compressor of Example 1, this compressor does not have the function and effect of the convex portion 117d, but can have other functions and effects.

Embodiment 3）

[0072]Such as Figure 8 As shown, the length of the movement preventing wall 117f in the bracket 31 of the compressor of Embodiment 3 is smaller than the radius of the lead wire 9b. In addition, the bracket 31 adopts a smaller inclined surface 117g than the inclined surface 117e of the first and second embodiments. Other structures are the same as in Embodiment 2.

[0073] In this compressor, since the inclined surface 117g is smaller than the inclined surface 117e of Embodiments 1 and 2, the amount of elastic deformation when the lead wire 9b passes through the insertion opening 117b is relatively large, and the lead wire 9b is difficult to fall out of the holding chamber 117a. However, since the length of the movement prevention wall 117f is relatively short, the lead wire 9b is easily dropped from the holding chamber 117a. These actions cancel each other out, and this compressor can exhibit the same level of action and effect as that of the compressor of the first embodim...

Abstract

Compressors have undesirable stations of manufacturing cost, product management, etc., are easy to automatically assemble brackets and are hard to remove wires of harness from the brackets. The compressor provided by the invention has an electromagnetic capacity control valve (7) fixed in the housing (3) and applying electrical effect on a syncline plate compression mechanism (5); and a harness (9) connecting the electromagnetic capacity control valve (7) with external electricity. A bracket (11) is fixed in the housing (3) and can hold a holding chamber (117a) of the wires (9b) of the harness (9) in the inner. The bracket (11) is formed with an insert port (117b) communicated with the holding chamber (117a) and inserting the wires (9b) into the holding chamber (117a) from the outside; and a moving block wall (117c) which can move to the surface of the housing (3) by contacting the wires (9b) in the holding chamber (117a) and assembling the wires (9b).

Description

technical field [0001] The present invention relates to compressors. Background technique [0002] The compressor includes a drive shaft that is rotationally driven from the outside, and a housing that supports the drive shaft and enables the drive shaft to rotate. A compression mechanism that performs a fluid compression action based on the rotation of the drive shaft is incorporated in the housing. As a compression mechanism, there is a swash plate type compression mechanism that has a swash plate that rotates together with a drive shaft, and the piston reciprocates in the cylinder according to the inclination angle of the swash plate, thereby changing the volume of the compression chamber. [0003] In such compressors, since electrical action is applied to the compression mechanism, electrical components may be fixed to the housing. For example, in order to automatically control the discharge capacity of the compression mechanism, an electromagnetic capacity control val...
