Description

[Detailed Description of the Invention] The present invention relates to a device for fixing lead wires, crossover wires, etc. of motors, generators, transformers, etc.

End portions of conductive wires such as lead wires, outgoing wires, crossover wires, etc. are often connected to each other or to a lead wire.

In such cases, if the position of the end of the conductor is not constant,
Difficult to work.

In particular, when connecting automatically using the conductor twisting device shown in JP-A No. 49-112189, or when inserting a lead wire into a solder tank and soldering there, It is often inconvenient if the end position is not constant.

In view of the above-mentioned points, the present invention fixes the position of the conductive wire end so that operations such as connection, insulation coating peeling, or processing can be easily performed.

The present invention includes a substrate provided with a plurality of notches opening outward, and rotates on a plane perpendicular to the thickness direction of the substrate,
Then, the opening of each notch is opened to make it into a closed state, and in the closed state, the closed side can move toward the back of the notch, so that the same number of clampers as the notches are provided, and the clampers are moved so that the closed side moves toward the back of the notch. This is a device for fixing the end of a conductive wire for an electrical device, which has a ratchet mechanism between the board and the clamper that prevents movement in the opposite direction when the wire advances in the opposite direction.

The illustrated embodiment shows an example in which the present device is used to fix a lead wire of a motor stator winding. In the figure, reference numeral 1 denotes a substrate, in which a plurality of notches 13 opening outward are provided radially.

As shown in Fig. 1, the board 1 is inserted into the inner diameter of the connection side of the stator coil 2, and by turning the screw 5 at the center, the collet 7 on the outer diameter side is opened by the taper ring 6, and fixed on the inner diameter surface of the core. .

The clampers 12 are pivotally connected to the substrate 1 by pins near the notches 13, respectively, so that the openings of the notches 13 can be closed or opened.

The clamper 12 is retracted from the notch 13 by a bow tension spring 16 provided between the clamper 12 and the substrate 1, and the notch 13
It is configured to receive force in the opening direction.

Further, the clamper 12 has arc-shaped ratchet teeth 20, and the stopper pin 14 is attached to the substrate 1 through the ratchet teeth 20.
One end of the spring 15, which acts to press the ball toward zero, is fixed.

The coil terminals 9 and 10 are inserted into the notch 13 by hand, for example, and clamped at the back 19 of the notch 13 by the side 18 of the clamper 12.

The clamper 12 is fixed by a ratchet mechanism 21 consisting of a stopper pin 14, a spring 15, and ratchet teeth 20 of the clamper 12 to prevent it from returning.

By applying the clamper 12 only at the connection points of the stator, the positions of the coil terminals 9 and 10 can be reliably regulated.

To remove the clamper 12, pull the head of the stopper pin 14 inward, the clamper 12 will open outward by the spring 16, and the board 1 can be easily removed by loosening the center screw 5 and lifting it up.

Acrylic material 8 is attached to the part that enters the inner diameter side of the coil so as not to leave any marks on the coil.

In addition, in 3, the armature core 4 is a groove insulator.

Further, reference numeral 11 is a seat for receiving the screw 5, and is integrated with the substrate 1.

17 is a seat that receives one end of the spring 16.

Since the present invention has the above-mentioned configuration, it is possible to fix the leader wires one bundle at a time by operating the clamper one by one, so it is possible to accurately adjust the holding position of the leader wires, and to connect the conductor wires of electrical equipment. It can be said that it mechanizes work and saves labor, particularly man-hours are reduced and quality is improved.
