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 kind of lead wire is pulled out from the electromagnetic clutch and fixed once on the outer surface of the compressor.
Then, it is usually connected to a controller for controlling energization.

For example, Japanese Utility Model Laid-Open No. 58-145709 discloses several structures for fixing the lead wire used in the compressor to the outer surface of the compressor body by using a fixing aid. An example is one in which a lead wire is held in pressure contact with the outer surface of the compressor by a clamp screwed to the compressor. 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
Since the screw holes for screwing must be specially processed on the outer surface of the compressor body, and the latter also needs to form the receiving port on the protrusion provided on the outer surface of the compressor body, the following is listed. I have a problem to do.

1. Crimp the terminal to the tip of the lead wire,
Bushing must be done before crimping the terminals.

2. It takes time to insert the bush into the mouth.

3. The socket has a weak shape and is easily chipped.

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 without fear of the above-mentioned problems.

[0009]

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 by using a fixing aid, the protrusion is a root portion. The projection end portion has a larger dimensional relationship than the projection end portion, and the fixing aid has a projection holding portion elastically fitted to the outside of the projection portion and held by the projection portion by the dimensional relationship, A lead wire fixing structure for a compressor is obtained, which has a wire holding portion that holds a lead wire.

It is preferable that a concave portion and a convex portion that are fitted to each other be provided in the projection portion and the projection holding portion, and that the fixing aid be positioned with respect to the projection portion by fitting the concave portion and the convex portion. .

The wire holding portion may have a through hole for inserting and holding the lead wire, or may hold the lead wire in cooperation with the projecting end portion of the projecting portion. Good.

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

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 schematically shows an example in which the present invention is applied to a car air conditioner compressor. The compressor comprises a front housing 2 formed as part of the compressor body 1. The front housing 2 includes an electromagnetic clutch (not shown) for applying and releasing power transmitted to a compression mechanism (not shown) built in the compressor body 1. A lead wire 3 is drawn from the front housing 2 for energizing the electromagnetic clutch. 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). In this way, the controller can control the energization of the electromagnetic clutch.

The compressor body 1 has a protrusion 5 which can be used for mounting on an engine of an automobile or the like. The protrusion 5 is integrally formed with the compressor body 1 by casting,
The width extending in the direction intersecting with the axial direction of the compressor, and the width of the tip end portion of the portion where the clip 4 is fitted is slightly larger than that of the root portion (that is, the axial dimension of the compressor).

Referring also to FIG. 2 showing an example, the clip 4
Is made of synthetic resin and is attached to the protrusion 5 so as to sandwich it, and has a protrusion holder 7 and a wire holder 6. The protrusion holding portion 7 has a dimension such that it is elastically fitted to the outside of the protrusion 5 and is retained by the protrusion 5 due to the dimensional relationship between the root portion and the protrusion end portion of the protrusion 5. The wire holding portion 6 has a through hole 8 through which the lead wire 3 is inserted and held.

In order to fix the lead wire 3 to the protruding portion 5 using the clip 4, the lead wire 3 is inserted into the through hole 8 of the wire holding portion 6 of the clip 4, and the protruding holding portion 7 of the clip 4 is fixed. It is fitted to the outside of the protrusion 5. On the contrary, if the clip 4 is separated from the protrusion 5, the clip 4 can be easily removed from the protrusion 5. Therefore, this clip 4 can be reused.

FIG. 3 shows another example of the clip 4. In this clip 4, a groove 9 is formed in the wire holding portion 6. This groove 9 is for receiving the lead wire 3.
Therefore, the clip 4 of FIG. 3 holds the lead wire 3 in cooperation with the protruding end portion of the protruding portion 5.

FIG. 4 shows still another example of the clip 4.
In the clip 4, the protrusion holding portion 7 is provided with a recess 11 that engages with a protrusion (not shown) provided on the protrusion 5. According to this, positioning of the clip 4 becomes more reliable, stable holding is obtained, and the posture is also stable.

FIG. 5 shows an example in which the clip 4 is made of a metal plate.

[0020]

As described above, according to the present invention,
The lead wire can be fixed to the outer surface of the compressor body without performing any special processing on the compressor body.
