Wire harness mounting structure

Abstract

To reduce the number of parts and the effort required for installation. [Solution] A routing groove is provided at the coil end of the stator between the thermistor and the connector for routing the wire harness between the coils. The wire harness is then placed in the routing groove and fixed to it by adhesive. This reduces the number of parts and the effort required for installation compared to cases where mounting parts such as brackets and clips are used.

Description

Technical Field

[0001] The present disclosure relates to an attachment structure of a wire harness.

Background Art

[0002] Conventionally, as an attachment structure of this type of wire harness, a base bus bar is arranged between a stator and a bus bar unit that supplies power to the coils of the stator, and a thermistor is arranged in a thermistor holding portion formed in this base bus bar has been proposed (see, for example, Patent Document 1). The lead wire of the thermistor is guided radially inward of the base bus bar and axially led out from a lead wire guiding portion, and is wired axially along the inner peripheral wall of the bus bar unit and fixed by a blanket or a clip.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above-described attachment structure of the wire harness, since it is fixed by a blanket or a clip, parts such as a blanket and a clip are required, and it takes time to attach the lead wire. In addition, there is also a case where the wire harness is damaged due to damage to the blanket or clip.

[0005] The main object of the attachment structure of the wire harness of the present disclosure is to reduce the number of parts and the labor for attachment.

Means for Solving the Problems

[0006] The attachment structure of the wire harness of the present disclosure has adopted the following means in order to achieve the above main object.

[0007] The wire harness mounting structure of this disclosure is A wire harness mounting structure for attaching a wire harness, which encloses the lead wires connecting the thermistor and the connector in a tubular shape, to the stator of a motor, A routing groove is provided between the coils at the coil end of the stator between the thermistor and the connector for routing the wire harness, and the wire harness is fixed to the routing groove by adhesive while it is positioned in the routing groove. It is characterized by the following:

[0008] In the wire harness mounting structure of this disclosure, a routing groove is provided for routing the wire harness between the coils at the coil end of the stator between the thermistor and the connector. The wire harness is then placed in the routing groove and fixed to the routing groove by adhesive. In other words, the wire harness is placed in the routing groove and fixed by adhesive. This eliminates the need for mounting parts such as brackets and clips, thus reducing the number of parts. Furthermore, since the wire harness is only placed in the routing groove and fixed by adhesive, the effort required for installation is reduced compared to securing it with brackets or clips. In addition, by placing the wire harness in the routing groove, wear and breakage due to wire harness detachment and twisting can be suppressed.

[0009] In the wire harness mounting structure of this disclosure, the thermistor and the connector are arranged on the outer circumference side of the coil end, and the routing groove may be formed between the outermost coil at the coil end and the coil immediately inside it. Alternatively, the routing groove may be formed in a circumferential manner. Or, the wire harness may be routed in the routing groove and bonded and fixed with varnish. [Brief explanation of the drawing]

[0010] [Figure 1] This is a schematic diagram showing a wire harness mounting structure 20 as one embodiment of the present disclosure. [Figure 2] This is a schematic cross-sectional view showing section AA of Figure 1. [Modes for carrying out the invention]

[0011] Next, embodiments for implementing this disclosure will be described. Figure 1 is a schematic diagram showing a wire harness mounting structure 20 as one embodiment of this disclosure, and Figure 2 is a schematic cross-sectional view showing cross section AA of Figure 1.

[0012] The wire harness mounting structure 20 of the embodiment is a mounting structure for a wire harness 26 in which lead wires 25a and 26a connecting a thermistor 22 mounted on the outer circumference of the motor stator 30 and a connector 24 located on the outside of the stator are covered with a tube.

[0013] In the wire harness mounting structure 20 of the embodiment, as shown in Figures 1 and 2, the portion of the outermost coil 40 at the coil end of the three-phase coil wound around the stator 30 between the thermistor 22 and the connector 24 is formed to protrude outward, thereby providing a routing groove 48 between the coil 40 and the inner coil 42, through which a wire harness 26 can be routed. This routing groove 48 is formed concentrically around the upper left third of the circumference in Figure 1. The wire harness 26 is then positioned to be embedded in this routing groove 48, and the wire harness 26 is bonded and fixed to the routing groove 48 from the end side at several points using an adhesive 48 such as varnish.

[0014] In this way, the wire harness 26 is positioned so as to be embedded in the routing groove 48 formed between the coil 40 and the coil 42, and the wire harness 26 is fixed to the routing groove 48 with adhesive 48, eliminating the need for mounting parts such as brackets and clips, thus reducing the number of parts. Furthermore, compared to securing with brackets and clips, the effort required for installation is reduced. Moreover, by positioning the wire harness 26 so as to be embedded in the routing groove 48 formed between the coil 40 and the coil 42, it is possible to suppress the wire harness 26 from falling out, wear due to twisting, and breakage.

[0015] In the wire harness mounting structure 20 of this embodiment, a routing groove 48 is provided between the outermost coil 40 and the coil 42 inside it, and the wire harness 26 is positioned to be embedded in this routing groove 48. However, a routing groove may also be provided between the coil 42 that is not the outermost and the coil 44 inside it, and the wire harness 26 may be positioned to be embedded in this routing groove.

[0016] In the wire harness mounting structure 20 of this embodiment, the wire harness 26 is fixed to the routing groove 48 from the end side at several points using an adhesive 48 such as varnish. In this case, an adhesive other than varnish may be used.

[0017] The correspondence between the main elements of the embodiment and the main elements of the invention described in the section on means for solving the problem will be explained. In the embodiment, thermistor 22 corresponds to "thermistor", connector 24 corresponds to "connector", and wire harness 26 corresponds to "wire harness". Also, routing groove 48 corresponds to "routing groove".

[0018] Note that the correspondence between the main elements of the embodiments and the main elements of the invention described in the section of means for solving the problems is an example for specifically explaining the mode for implementing the invention described in the section of means for solving the problems in the embodiments, and thus does not limit the elements of the invention described in the section of means for solving the problems. That is, the interpretation of the invention described in the section of means for solving the problems should be made based on the description in that section, and the embodiments are merely specific examples of the invention described in the section of means for solving the problems.

However, the present disclosure is not limited to such embodiments, and it is needless to say that the present disclosure can be implemented in various forms without departing from the gist of the present disclosure.
