Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lead wire processing structure used in a compressor, and more particularly to a structure for fixing the lead wire to an outer surface of a compressor body.

[0002]

2. Description of the Related Art For example, in a car air conditioner compressor, a lead wire is used to energize an electromagnetic clutch or the like. This type of lead wire is usually pulled out from an electromagnetic clutch or the like and once fixed to the outer surface of the compressor body, and then connected to a controller for controlling energization.

For example, Japanese Utility Model Laid-Open No. 58-14570 discloses some structures for fixing lead wires used in a compressor to the outer surface of a compressor body by using a fixing aid. In one example, the lead wire is held in pressure contact with the outer surface of the compressor body by a clamp that is screwed to the compressor body. Further, there is also a structure in which a projection is provided on the outer surface of the compressor body, and a bush previously attached to a lead wire is fitted and held in the receptacle.

[0004]

[Problems to be Solved by the Invention] However, the former is
It is troublesome to fix the lead wire with the clamp to the outer surface of the compressor body while fixing the screw. The latter requires the work of attaching the bush to the lead wire and the work of fitting the bush into the receiving port, and is complicated because the work involves two stages.

Therefore, an object of the present invention is to provide a structure capable of fixing the lead wire to the outer surface of the compressor body by a simple and easy operation.

[0006]

According to the present invention, in a structure in which a lead wire used in a compressor is fixed to a protrusion provided on an outer surface of a compressor body using a fixing aid, the protrusions are opposed to each other. And a wire receiving surface adjacent to the both side surfaces, wherein the fixing aid is a lead wire pressing portion facing the wire receiving surface, and both ends of the lead wire pressing portion face the both side surfaces. And a pair of fixing portions that are extended and fixed to the protrusions while holding the lead wires between the lead wire holding portion and the wire receiving surface. The lead wire fixing structure can be obtained.

At least one of the both side surfaces may be provided with a concave portion, and the fixed portion may be provided with a convex portion that is engaged with the concave portion, or at least one of the both side surfaces may be provided with a convex portion. The fixed portion may be provided with a concave portion that is locked to the convex portion. In these cases, it is desirable that the pair of fixing portions have elasticity so as to urge the fixing portions toward the both side surfaces.

It is preferable to provide a groove on the wire receiving surface for receiving a part of the side surface of the lead wire.

It is preferable that the lead wire holding portion has a bridge portion connecting the pair of fixing portions to each other, and a finger portion protruding from the bridge portion and pressing the lead wire against the wire receiving surface.

The protrusion may be a portion used for mounting the compressor.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows a compressor for a car air conditioner. This compressor includes a compressor body 1 and an electromagnetic clutch 2 for applying and releasing the power transmitted to the compressor body 1. A lead wire 3 is drawn from the electromagnetic clutch 2 for energizing the electromagnetic clutch 2. The lead wire 3 is fixed to the outer surface of the compressor body 1 by using a fixing aid, that is, a clip 4, and then connected to a controller (not shown). Thus, the controller can control the energization of the electromagnetic clutch 2.

Referring to FIG. 2, the compressor body 1 has a protrusion or boss 5 which is used for mounting on an engine of an automobile. The boss 5 has opposite side surfaces 6 facing each other.
And a wire receiving surface 7 adjacent to both side surfaces thereof.
Further, a mounting hole 8 for inserting a mounting bolt is provided between both side surfaces 6 of the boss 5. Notches or recesses 11 are formed on both side surfaces 6 and grooves 12 are formed on the wire receiving surface 7. Groove 1
Reference numeral 2 extends between both side surfaces 6 to receive a part of the side surface of the lead wire 3 shown in FIG.

The clip 4 is attached to the boss 5 so as to sandwich it, and the lead wire holding portion 13 facing the wire receiving surface 7 and both side surfaces 6 of the boss 5 from both ends of the lead wire holding portion 13. And a pair of fixing portions 14 that extend and are fixed to the boss 5. The lead wire holding portion 13 has a bridge portion 15 in which a pair of fixing portions 14 are coupled to each other, and a finger portion 16 protruding from the bridge portion 15. The pair of fixing portions 14 are provided with a claw portion, that is, a convex portion 17 that is locked in the concave portion 11. Such a clip 4 is made of synthetic resin or metal so that the pair of fixing portions 14 are elastically biased toward both side surfaces 6 of the boss 5 when attached to the boss 5.

Using this clip 4, the lead wire 3 of FIG.
To fix the to the boss 5, the clip 4 is fitted to the boss 5 along the lead wire 3 as shown in FIG. Then, the convex portion 17 of the pair of fixing portions 14 is replaced with the concave portion 11 of both side surfaces 6 of the boss 5.
Engage with. At this time, the dimensional relationship is set so that the finger portion 16 presses the lead wire 3 into the groove 12 of the wire receiving surface 7. As a result, the lead wire 3 is pressed and fixed in the groove 12 of the wire receiving surface 7. This fixing work can be performed with one touch,
It's easy.

The pair of fixing portions 14 are separated from each other and the convex portion 1 is formed.
The clip 4 can be easily removed from the boss 5 by detaching the clip 7 from the recess 11. Therefore, this clip 4 can be reused.

The mounting hole 8 of the boss 5 shown in FIG. 2 extends in the axial direction of the compressor. However, as shown in FIG. 4, the mounting hole 8 extends from the boss 18 extending in the direction intersecting the axial center of the compressor. However, it can be implemented in the same manner.

It is also possible to provide convex portions on both side surfaces 6 and to provide the fixed portion 14 with concave portions that are locked to the convex portions.

[0018]

As described above, according to the present invention,
The lead wire can be fixed to the outer surface of the compressor by a simple and easy operation.
