As shown in the attached figure 4 of the specification, the current old Y2 series 335 wiring board is of a flat plate design and is supported and fixed through a mounting base, but when the wiring board is used for wiring, a wiring end needs to be bent by about 90 degrees (as shown in the attached figure 4 of the specification and at the position A), so that the wiring board is inconvenient to mount, needs to be bent by labor, is easy to damage an external insulating skin and an internal circuit, and is thicker and not easy to be bent; the other point is that after the wiring ring sleeve at the tail end is screwed and fixed on the threaded wiring terminal by a nut, the wiring ring sleeve is influenced by the force that the wire is bent for 90 degrees and is restored to deform, and the vibration of a motor is added, so that the insulation skin and the internal circuit are easily dragged and bound at the position B in the attached figure 4 of the specification, the internal circuit is forced to be pulled out and exposed from the position B in the attached figure 4 of the specification, and safety accidents are easily caused. Finally, since the wiring harness of the high-power three-phase motor is thicker, after the wiring ring is screwed on the threaded wiring terminal through the nut, as shown in the position C in the attached drawing of the specification and in figure 4, the whole wiring ring and the wiring sheet of the internal circuit can be bent to form a bent-arc wiring sheet to adapt to the height difference H between the wiring ring and the outer side of the insulating sheath, and the high-power three-phase motor is easily fatigue aged and broken due to the influence of the vibration environment of the motor, so that safety accidents are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a Y2-335 wiring board for a motor junction box, which is characterized in that when wiring, a wiring terminal does not need to be bent for 90 degrees any more, but only needs to be bent for 120 degrees at a wire inlet hole far away from the wiring terminal, and the bent position is farther away from a threaded wiring terminal and is easier to finish, so that a series of problems caused by 90-degree bending of the wiring terminal are avoided; and the design height of the metal backing ring is greater than the height difference H between the wire connecting ring and the outer side of the insulating sheath, so that the defect that the wire connecting ring is easy to fatigue and age and break due to the influence of the vibration environment of the motor is overcome.

In order to achieve the purpose, the utility model is realized by the following technical scheme:

the Y2-335 wiring board for the motor junction box comprises a mounting base and a wiring board, wherein the mounting base is provided with a wire inlet hole and a mounting hole, the wiring board is arranged on the mounting base, and the wiring board is provided with a threaded wiring terminal; the line board is the type of falling V line board, the setting of screw thread terminal perpendicular to line board face, screw thread terminal bottom is equipped with the metal backing ring.

The included angle of the top of the inverted V-shaped line plate is 60 degrees.

And a material-saving lightening hole is formed in the mounting base below the inverted V-shaped linear plate.

The inverted V-shaped line plate is provided with ribs, and steel bars are arranged in the ribs.

Compared with the prior art, the utility model has the beneficial effects that:

as shown in the attached figure 2 of the specification, a lead penetrates through a through hole at the bottom of the junction box through the wire inlet hole, the wire inlet hole is bent at 120 degrees, the junction box is sleeved on the threaded wiring terminal, and the nut is screwed for fixing. When wiring, the wiring end no longer need 90 degrees turn round, and only in the inlet wire hole department of keeping away from the wiring end 120 degrees turn round can, and the department of turning round is farther apart from the screw thread terminal, changes the completion to avoid a series of problems that 90 degrees turn round of wiring end brought.

The bottom of the threaded binding post is provided with a metal backing ring, the design height of the metal backing ring is greater than the height difference H between the wire connecting ring and the outer side of the insulating sheath, and the defect that the wire connecting ring is easy to fatigue and age and break due to the influence of the vibration environment of the motor is avoided;

whole line board is the type of falling V line board, can play certain bradyseism effect under the vibrations environment to it drags to reduce the rigid of wiring end receiving vibrations, thereby improves life and security.
