Description

AC brushless exciter junction box

Technical Field

The utility model relates to an exciter terminal box makes technical field, especially relates to an exchange brushless exciter terminal box.

Background

The prior casing of the junction box of the produced AC brushless exciter with various capacities is mostly made of cast aluminum ZL107 material. Because the material has a complex structure and adopts a casting mode, the manufacturing cost is high and the processing period is long.

The existing exciter junction box has the following defects: (1) the material cost is high; the cast iron ZL107 is high in price, and unit cost is difficult to reduce under the condition that the batch size is not large.

(2) The processing is time-consuming; and after the terminal box base and the terminal box cover are cast, finish machining is required, and the machining period is long.

(3) The cost is high; this is also a result of the 2 factors above.

(4) Spare parts are few; due to high cost, in order to reduce the occupation of capital, the number of processing spare parts of the junction box with the structure is small, the storage of a warehouse is also small, the difficulty in production management is increased, and the AC brushless exciter junction box is designed aiming at the problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an exchange brushless exciter terminal box possesses the advantage of processing convenience, strong adaptability, saving cost, has solved with high costs, adaptability is low, the difficult problem of processing.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an exchange brushless exciter terminal box, includes the terminal box seat, be provided with the wiring board in the terminal box seat, the wiring board with fix on the terminal box seat through wiring board fixing bolt, the through wires hole that runs through the terminal box seat is seted up at the wiring board middle part, terminal box seat right-hand member is fixed with the terminal box lid, two wire holes, one have been seted up to terminal box seat lower extreme all be provided with the pipe box in the wire hole.

Furthermore, an insulating sheet is arranged between the wiring board and the terminal box base.

Further, each pipe sleeve comprises a male head fixing part and a sealed female head, the male head fixing part is fixed in the wire hole, the male head fixing part is fixed through a nut, and the sealed female head is fixed at the lower end of the male head fixing part.

Further, the terminal box base is fixed through a fixing screw.

Furthermore, a plurality of wiring terminals are fixed on the wiring board.

Compared with the prior art, the utility model beneficial effect who has is:

1. the split type processing is adopted, so that the processing is convenient, and the manufacturing period of the whole junction box is further reduced; the adaptability is strong, the exciter with different capacities can be adapted, and only the position of a handle hole on the terminal box base needs to be changed and processed; casting is not needed, and the material selection is more flexible and diversified; the cost is saved, the price of the junction box with the new structure is only 10-20% of the original price of the junction box, and the cost reduction amplitude is large.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.

fig. 2 is a schematic side view of the ac brushless exciter junction box according to the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, an alternating current brushless exciter terminal box comprises a terminal box base 1, a wiring board 2 is arranged in the terminal box base 1, the wiring board 2 is fixed on the terminal box base 1 through a wiring board fixing bolt 23, a threading hole 21 penetrating through the terminal box base 1 is formed in the middle of the wiring board 2, a terminal box cover 3 is fixed at the right end of the terminal box base 1, two wire holes 4 are formed in the lower end of the terminal box base 1, and a pipe sleeve 5 is arranged in each wire hole 4.

An insulation sheet 22 is arranged between the wiring board 2 and the wiring box base 1.

Each pipe sleeve 5 comprises a male head fixing part and a sealed female head, the male head fixing part is fixed in the wire hole 4, the male head fixing part is fixed through a nut, and the sealed female head is fixed at the lower end of the male head fixing part.

The junction box base 1 is fixed through a fixing screw 6.

A plurality of binding posts 7 are fixed on the wiring board 2.

When in use, the junction box is assembled as shown in the figure, and the junction box base, the wiring board and the insulating plate are fixed on the exciter base through bolts. Except for the processed bolt holes and unthreaded holes between the junction box base and the junction box, the junction box base and the junction box cover have no processed holes. Particularly, phi 7, phi 18 and phi 25 on the bottom surface of the terminal box base can be processed according to the positions and the sizes of different threaded holes on the exciter base. Such holes are very easy to machine during assembly, due to the small wall thickness of the terminal block base. The internal lead is connected out from the lower part and can also be connected out from the two sides through the sleeve, so that the connection mode is more flexible and diversified, and the mode that the internal lead can only be connected out from the lower part in the original structure is avoided.
