Embodiment Construction
[0013] The combination of motor lead wire terminals includes a pair of mutually matched terminals, each terminal comprises a pure copper cylinder 1, one end of the cylinder is opened with a connection counterbore 2, and the other end of the cylinder is along the axis of the cylinder The semi-cylindrical body 3 and the cylindrical bump 4 are machined in the direction. The intersection contour line of the semi-cylindrical body 3 and the cylinder body 1 is composed of the end face diameter of the cylinder body and the semicircle arc line. The intersection surface of the bump 4 and the cylinder body 1 The contour line is composed of a chord parallel to the diameter of the semi-cylinder (side plane) on the end face of the cylinder and a minor arc corresponding to the chord on the end face of the cylinder. A circular groove 6 is processed on the inner plane of the cylinder 3, and a cylindrical pin 7 is fixed in the circular groove 6; a cylindrical tenon 8 is processed on the end face...

The invention relates to motor parts, in particular to a motor lead connector lug, solving the problems of easy burning loss, inconvenient disassembly and assembly, easy scarification for an insulating sheath and the like of the existing motor lead connector lug. The motor lead connector lug comprises a pair of connector lugs which are matched with each other and respectively comprise a pure copper cylinder, a connecting counter bore that is opened in one end surface of each cylinder, a halfcylinder and a cylindrical projection that are processed on the other end surface of each cylinder along the axes direction of the cylinder, a bayonet key slot that is formed between the halfcylinder and the cylindrical projection, a ring-shaped groove processed on the plane at the inner side of the halfcylinder, and a cylindrical pin fixed inside the ring-shaped groove; in addition, a cylindrical tenon is processed on the end surface of the halfcylinder along the axes direction of the cylinder. When in the connection between lines, only the same connector lug is needed to be used at the two ends, so that firm and reliable connection between lines can be realized, thus being convenient and efficient. After being connected, the two connector lugs have uniform thickness and can not lacerate the sheath, thus effectively avoiding the fault of burning loss for the motor lead connector lug. Therefore, the motor lead connector lug is especially suitable for the connection between lines of a pulling motor and a locomotive jug line.
Description
technical field [0001] The invention relates to a motor accessory, in particular to a motor lead wire terminal assembly. Background technique [0002] The existing motor lead wire terminal is combined into a flat plate shape. The connection method between the motor lead wire and the large wire (power supply wire) is usually to connect the two ends of the terminal with bolts, and then cover the outer layer with a rubber insulating sheath and lock it with a wire clip (as shown in Figure 1) . This kind of connection method has the following disadvantages: 1. It is easy to cause the bolts to loosen during operation, resulting in burning of the lead wires. 2. It is inconvenient to disassemble and assemble, which is not conducive to daily maintenance. And there is also the potential risk of bolt slipping and bad buckle. 3. Connecting bolts and nuts may cause the outer sheath to bulge, which may easily scratch the sheath or cause the sheath to loosen, thus making the insulation...
