Description

TECHNICAL FIELD The present invention relates to a terminal block for stator winding terminal treatment of an electric motor.

2. Description of the Related Art Conventionally, after winding a wire end wire around a terminal fixed to a terminal block for wire end processing, there was no terminal with a wire end wire cutting function, so scissors etc. The winding end wire was cut with a tool. Therefore, there has been a demand for a terminal block for stator winding terminal processing, which is capable of shortening the winding work time and has good workability in cutting the winding terminal wire.

Conventionally, in this type of terminal block for stator winding terminal treatment, as shown in FIG. 4, the terminal block body 103 is fixed to the upper surface of the winding terminal 102 of the stator 101 by a method such as adhesion, The winding terminal wire 105 is wound around the plurality of L-shaped terminals 104 provided on the base body 103.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to cut an unnecessary portion of the winding terminal wire 105 after the work of winding the winding terminal wire 105 around the terminal 104 is completed. Had no sharp parts, so it was cut with a tool such as scissors,
There is a problem that extra time is required for winding work.

The present invention solves such a problem, and an object thereof is to reduce the time required for winding the stator.

Means for Solving the Problems In order to solve this problem, the present invention is fixed to the terminal block body fixed to a part of the upper surface or the side surface of the winding end of the stator by means such as press fitting. After winding the terminal wire of the stator, the terminal has terminals for electrical connection by soldering or the like, and part of the terminals is sharply processed.

With this configuration, a part of the terminal is sharply processed, and the terminal itself has a winding cutting function, and as soon as the winding of the winding terminal wire around the terminal is completed, the sharp portion provided on the terminal Since the workability of cutting the winding terminal wire is improved, and the winding terminal wire is cut in the vicinity of the terminal, the risk of short-circuiting the surplus part with the adjacent terminal is eliminated, and the stator It is possible to shorten the winding work time and improve the reliability.

Embodiment An embodiment of the present invention will be described below with reference to FIGS.

In the figure, reference numeral 1 denotes a terminal block body, which is fixed to the upper and side surfaces of a winding terminal 3 of a stator winding wound around a stator 2 by a resin such as an adhesive or a drawing thread. The terminal base body 1 has a terminal 4 fixed by press-fitting, insert molding or the like, and a part 5 of the terminal 4 is provided with a sharpened portion. In the above structure, the winding terminal wire 6 is wound around the rising portion of the terminal 4 a prescribed number of times, and immediately thereafter, the unnecessary portion of the winding terminal wire 6 is removed by the sharply processed portion 5 provided on the terminal 4. Terminal 4
Can be cut in the immediate vicinity of.

As described above, according to the present embodiment, the unnecessary portion of the winding terminal wire 6 can be cut at the same time when the winding operation of the winding terminal wire 6 is completed, and the winding work time of the stator can be shortened and the winding terminal wire can be shortened. It is possible to prevent a short circuit between the adjacent terminals of the wire.

Effects of the Invention As will be apparent from the above description of the embodiments, the present invention makes the unnecessary portion of the winding end wire into the terminal at the same time when the winding end wire winding work around the terminal of the terminal block for the stator winding end is completed. It is possible to cut at the formed sharp portion, shorten the stator winding work time, prevent short-circuiting with the adjacent terminal, and achieve the effect of improving reliability.
