Abstract
The utility model discloses an in-oil wiring terminal of a transformer. The in-oil wiring terminal of the transformer comprises two wiring boards and a stepped sleeve which is arranged between the two wiring boards, wherein the wiring boards are respectively provided with eight wiring holes, and the upper part of the stepped sleeve is provided with an internal threaded hole. The in-oil wiring terminal of the transformer is directly casted into an integral configuration, changes the method that multiple pieces are manufactured separately and then welded into an integrity, and the manufacturing is simple; and the in-oil wiring terminal is free from welding, has no welding slag, can save materials and shorten processing time, and improves the mechanical property and conductive effect.
Description
Technical field
The utility model belongs to connection terminal structure technical field, particularly a kind of transformer oil middle connecting terminal.
Technical background
The oily middle connecting terminal of now conventional this structure of transformer, is that a plurality of parts are saved to welding fabrication through welding manner one, and wherein some parts also needs through cutting processing, complex manufacturing process; In manufacturing process, can produce welding slag, mechanical performance is lower, affects conductive effect, adopts the independent machine-shaping of a plurality of parts meeting to cause material unaccounted-for (MUF) simultaneously simultaneously, improves production cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of transformer oil middle connecting terminal simple, consumptive material is few of making.
The purpose of this utility model can be achieved through the following technical solutions:
A middle connecting terminal, comprise the first terminal block, the second terminal block and be located at the first terminal block and the second terminal block between ladder bushing, the first terminal block, the second terminal block and ladder bushing integral casting forming.
Preferably, on terminal block, be respectively equipped with eight wiring holes.
Preferably, ladder bushing top is shaped with internal thread hole.
Adopt the beneficial effect of technique scheme to be: the utility model is provided with eight wiring holes on rectangle terminal block, facilitates wiring; Ladder bushing top is shaped with internal thread hole, and convenient and transformer conducting bar is fastenedly connected; The utility model integral casting forming, makes simply, saves material, and has improved mechanical performance and conductive effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, the first terminal block, 2, ladder bushing, the 3, second terminal block, 4, wiring hole, 5, internal thread hole.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model and structure are described, so that those skilled in the art understand.
As shown in Figure 1, a kind of transformer oil middle connecting terminal, comprise the first terminal block 1, the second terminal block 3 and connect the ladder bushing 2 of the first terminal block 1 and the second terminal block 3, the first terminal block 1, the second terminal block 3 and ladder bushing 2 integral casting formings, on the first terminal block 1 and the second terminal block 2, be respectively equipped with eight wiring holes 4, ladder bushing 2 tops are shaped with internal thread hole 5.
Transformer output power lug integral casting forming, makes simply, saves material, and has improved mechanical performance and conductive effect.
Above-mentionedly by reference to the accompanying drawings utility model is exemplarily described; obviously the utility model specific implementation is not subject to the restrictions described above; as long as this non-essential improvement that has adopted method design of the present utility model and technical scheme to carry out; or without improving, the design of utility model and technical scheme are directly applied to other occasions, all within protection range of the present utility model.
