[0002]

2. Description of the Related Art In the conventional motor wiring structure of this type, a coil is directly connected to a harness and is solidified by using high temperature solder or resistance welding.
Further, in the structure for fixing the harness to the motor, the harness is bound to the coil or the coil insulator by using a thread or the like, or fixed by an adhesive.

[0003]

Since the conventional motor wiring structure is constructed as described above, the following problems exist. That is, when using high temperature solder, the soldering tip temperature was as high as 400 ° C. and it was easily oxidized, so that workability was poor, soldering was poor, and the quality was poor. Also, the coil coating removal work is required,
The quality was poor. Further, the fixing of the harness is also vulnerable to vibration and the like when tied with a thread, and there is a problem in workability and environmental resistance when an adhesive is used.

The present invention has been made to solve the above problems, and in particular, it is an object of the present invention to provide a motor wiring structure capable of maintaining stable performance even under a severe motor usage environment. And

[0005]

In a motor wiring structure according to the present invention, a coil is attached to a tubular stator iron core through an insulator for a coil having an overall tubular shape, and a harness is connected to the coil. In the motor wiring structure configured as described above, an accommodating portion integrally formed with the coil insulator and located on the end side of the tubular stator iron core, and an L connected in parallel with the accommodating portion and connected to the harness. This is a configuration including a die terminal, a rising portion formed in the L-type terminal and connected to the coil, and a cover body provided in the storage portion for covering each of the L-type terminals.

More specifically, the rising portion and the coil are brazed via a brazing portion.

More specifically, the projection formed on the lower portion of the cover body is in contact with the L-shaped terminal.

More specifically, each engaging hole of the cover body is engaged with a plurality of engaging protrusions formed in the housing portion, and the engaging protrusions are heat-crimped.

[0009]

In the motor wiring structure according to the present invention, the L-shaped terminal is arranged in parallel in the storage portion formed at the end of the coil insulator holding the coil, and the harness and the coil are connected via the L-shaped terminal. Since the L-shaped terminal is connected and fixed by being covered with the cover body, the harness and the coil are surely connected, and reliability against vibration and heat is surely ensured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a motor wiring structure according to the present invention will be described in detail below with reference to the drawings. A reference numeral 1 in FIGS. 1 and 2 denotes a tubular stator iron core having a tubular shape, and the tubular stator iron core 1 is provided with a coil insulator 2 having an overall tubular shape. Each pole 1a ~
The coil 3 is wound and attached every 1 h.

The end portion 2a of the coil insulator 2, that is, the end portion 1a of the cylindrical stator iron core 1 is integrally formed in a direction orthogonal to the longitudinal direction of the cylindrical stator iron core 1. A substantially plate-shaped storage portion 4 is provided, and the storage portion 4 is formed with a plurality of recesses 6 for arranging the metal L-shaped terminals 5 side by side.

Engaging projections 6 are provided at positions adjacent to the respective recesses 6.
a is engaged, and a harness 7 is firmly fixed to each of the L-type terminals 5 by a caulking portion 5a. Connected to each other. further,
The coil 3 and the rising portion 5b are securely connected by the brazing portion 8 by brazing.

A cover body 10 made of resin having a plane area substantially equal to that of the storage section 4 is provided on the storage section 4, and a plurality of cover bodies formed on the lower surface of the cover body 10 are provided. The protrusions 10a of the L-shaped terminals 5 are
It is configured to come into contact with and press.

On the cover body 10, the engaging protrusions 6 are formed.
An engaging hole 11 is formed corresponding to a, and each engaging projection 6a engages with this engaging hole 11, and the tip of each engaging projection 6a projects from the upper surface of the engaging hole 11. As is well known, the cover body 10 is fixed to the accommodating portion 4 by caulking the protruding portion, and at the same time, each L-type terminal 5 is also fixed. Further, each tongue portion 10b of the cover body 10 constitutes a partition between the brazing portions 8.

Therefore, each of the harnesses 7 can be surely energized with the coil 3 via the L-shaped terminal 5 and the rising portion 5b. In addition, the above-mentioned L-shaped terminal 5,
The shapes of the storage section 4 and the cover body 10 are shown as an example, and the same operation as described above can be obtained even if the shape is slightly changed.

[0016]

Since the motor wiring structure according to the present invention is constructed as described above, the following effects can be obtained. That is, since the harness and the coil are connected via the L-shaped terminal, the reliability of the connection part and the workability are improved, and the mass production and stable quality of the motor that overcome the specifications in the bad environment under high temperature are achieved. Can be measured. In addition, since the harness is also fixed to the storage part integrated with the coil insulator, it is possible to obtain high quality that is resistant to vibration and adverse environment.
