Abstract
A secondary winding lead wire structure of a dry-type transformer comprises secondary winding lead wires and a cable conductor; a copper bar is fixed on the output terminal of each secondary winding lead wire; a bolt hole is formed on each copper bar; a blade terminal is fixed at the end of the cable conductor; a bolt hole is formed on the blade terminal; and a bolt passes through the bolt holes on the blade terminal and the copper bars so as to connect and fix the blade terminal with the copper bars through nuts. The utility model simplifies the lead wire structure; the lead wire coupling in the later period can be performed through bolt connection, which is very convenient and simple and saves a lead wire rack, thereby resulting in tidy and compact appearance and lower cost.
Description
Technical field
The utility model relates to dry-type transformer secondary winding pin configuration.
Background technology
The secondary winding lead-in wire of dry-type transformer is to be drawn by former line, the secondary winding pin configuration of existing dry-type transformer is that lead-in wire is drawn by lead frame on the transformer and cable welding, and structure is complicated, the existence of lead frame, make the transformer outward appearance loaded down with trivial details, and strengthened the volume of transformer.Above-mentioned pin configuration suits just to go between after transformer is finished suit and the connecting of cable, and the later stage is because the welding space is smaller, so that lead-in wire connects is inconvenient.
The utility model content
The purpose of this utility model is to propose the dry-type transformer secondary winding pin configuration that a kind of lead-in wire simple in structure, convenient connects.
In order to achieve the above object, the utility model adopts following technical scheme: the utility model comprises secondary winding lead-in wire and cable, on each secondary winding lead-in wire output, be fixed with copper bar, copper bar is provided with bolt hole, cable is fixed with lug plate on the termination, lug plate is provided with bolt hole, and a bolt connects lug plate with bolt hole on the copper bar by the bolt hole on the lug plate and fixed by nut with copper bar.
" L " type copper bar that described copper bar is formed by two flangings, described wire bonds is on a flanging of copper bar, and described bolt hole is arranged on another flanging.
The utility model has been simplified pin configuration, and the later stage lead-in wire connects, and only need connect by bolt, and is very convenient simple, and save lead frame, and it is clean and tidy, compact that outward appearance seems, can reduce cost.The utility model can be mid-term lead-in wire to be handled in the coil winding process, and the position that each lead-in wire is lifted one's head is controlled easily, has improved the dimensional accuracy of transformer; Mid-term lead processing, the welding space is bigger, and is more simple and convenient than later stage welding, can shorten the process-cycle, saves cost of labor; And can avoid the damage to coil during system of Himdu logic fire welding lead of former transformer later stage, favourable improving the quality of products.Reduce the chance that the later stage finished product is reprocessed because of lead-in wire connection error, increased reliability.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a configuration diagram of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is an application drawing.
Embodiment
See Fig. 1 and Fig. 2, present embodiment comprises secondary winding lead-in wire 1 and cable 4, is fixed with copper bar 2 on each secondary winding goes between 1 output, and copper bar 2 is provided with bolt hole, and bolt hole can be a screwed hole, also can be unthreaded hole.Cable is fixed with lug plate 3 on 4 terminations, lug plate 3 is provided with bolt hole, the bolt hole that passes through on the lug plate 3 of one bolt 5 connects lug plate 3 with bolt hole on the copper bar 2 with copper bar 2, be connected with pad 7 and nut 6 on the bolt 5, fixing by nut 6 butted line sheets 3 with copper bar 2, guarantee excellent contact.Described copper bar 2 by two flangings form for " L " type copper bar, described lead-in wire 1 is welded on another flanging 21, described bolt hole is arranged on another flanging 22 of copper bar.
Fig. 3 is the schematic diagram that is applied on the transformer.
