Abstract
The utility model provides a line ball board for motor wiring, includes top board and holding down plate, and the top board passes through the bolt to be connected with the holding down plate, is equipped with the cylindrical boss with motor terminal box terminal connection bottom the holding down plate, has opened the line ball recess respectively on the counterpressure face of top and bottom holding down plate, and wherein, is equipped with at the one end of line ball recess and ends the logical platform. This line ball board can help the workman to judge suitable threading length fast on the basis of firmly fixed cable conductor, has reduced the influence of human factor, has the advantage that strengthens electrical safety performance, eliminates the potential safety hazard.
Description
Technical Field
The utility model relates to a high-voltage motor technical field especially relates to a motor is line ball board for wiring.
Background
And a wiring board is arranged on a wiring terminal in the main wiring box of the high-voltage motor and used for fixing a introduced power cable. Generally, a cable head is inserted into a wire groove on a wire pressing plate and then is screwed and fixed through a bolt. However, due to manual operation, the situation that the wire end extends too long or too short during wiring can occur, and if the wire end is too long, the electrical gap between the wire end and the side wall of the junction box is too small, so that high-voltage discharge is caused, and explosion accidents are easily caused; if the short circuit is too short, the current passing through the contact surface is too large, so that the wiring position is burnt, and the safety of equipment is influenced. In actual operation, workers mostly rely on personal experience to judge the threading length, and in order to avoid the problem of over short, a mode of extending the cable head to a small section as much as possible is often adopted during threading; in order to avoid the problem of overlong length, the front end of the cable head is coated with an insulating material; the methods seem to solve the problem of over short or over long, but the operation is not strict, the method is not in accordance with the safety routine of the high-voltage motor operation environment and has larger human factor influence, and the coated insulating material has the problems of aging and falling, has uncertainty and has obvious potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a not enough to prior art exists, provide one kind and can strengthen electrical safety performance, reduce the human factor influence, eliminate the motor wiring of potential safety hazard and use line ball board.
For realizing the utility model discloses a technical scheme that the purpose adopted is: the device comprises an upper pressing plate and a lower pressing plate, wherein the upper pressing plate is connected with the lower pressing plate through bolts, a cylindrical boss connected with a wiring terminal of a motor junction box is arranged at the bottom of the lower pressing plate, pressing line grooves are respectively formed in opposite pressing surfaces of the upper pressing plate and the lower pressing plate, and a stop platform is arranged at one end of each pressing line groove.
The center of the cylindrical boss is provided with an internal thread through hole.
The distance between the inner wall surface of the stop platform and the outer edges of the upper and lower pressing plates is 3-5 mm.
According to the line ball board for motor wiring that above-mentioned scheme was made, through reasonable structural design, on the basis of firm fixed cable conductor, can help the workman to judge suitable threading length fast, reduced the influence of human factor, strengthened electrical safety performance, eliminated the potential safety hazard.

Detailed Description
The present invention will be further described with reference to the following detailed description.
Referring to fig. 1, the utility model discloses a motor is line ball board for wiring, the device include top board 1 and holding down plate 2, and top board 1 passes through bolt 3 and is connected with holding down plate 2, is equipped with the cylindrical boss 2-1 with motor terminal box terminal connection in 2 bottoms of holding down plate, and it has line ball recess 5 to open respectively on the counterpressure face of top board, holding down plate, wherein, is equipped with at the one end of line ball recess 5 and ends logical platform 4. The center of the cylindrical boss 2-1 is provided with an internal thread through hole 2-2. The distance between the inner wall surface of the stop table 5 and the outer edges of the upper and lower pressing plates 2 is 3-5 mm.
During installation, the lower pressing plate 2 is connected and fixed with a binding post on a motor junction box through the inner threaded hole 2-2 formed in the cylindrical boss 2-1, then the upper pressing plate and the lower pressing plate are connected through the connecting hole 1-1 in the upper pressing plate and the connecting hole 2-3 in the lower pressing plate by using the bolt 3, then a cable is introduced, a cable head is inserted into the bottom to touch the stopping platform 4, the appropriate length of the cable is reached, then the cable is screwed by the bolt 3, and the cable is fixedly compressed by the upper pressing plate and the lower pressing plate under the screwing action force. When the tension disc is operated, the requirements on the technical proficiency and experience of workers are not high, the length requirements of cables can be met only by inserting the cables to the bottom, and extra insulating materials do not need to be coated in advance, so that the interference of human factors is eliminated, the electrical safety performance is enhanced, and potential safety hazards are eliminated.
The above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will appreciate that; modifications to the embodiments of the invention or equivalent substitutions of parts of the technical features can be made without departing from the spirit of the technical solution of the invention, which shall all cover the technical solution of the invention claimed.
