Abstract
The utility model relates to a miniature dry type transformer for controlling or lighting, which comprises an iron core (6), a coil (7), a corner bender (1), and a wiring assembly (12). The utility model is characterized in that the wiring assembly (12) is composed of a wiring holder (10), a soldering lug (9), a binding screw, a cushion ring, a protection plate (8), and a cover plate (11); a plurality of grid type wiring terminals on the wiring holder (10) are used for mounting the soldering lug (9), the binding screw, and the cushion ring; one side or the wiring holder (10) is provided with the protection plate (8) to protect the soldering lug (9); the cover plate (11) is arranged on the wiring holder (10) to protect the wiring terminals. Compared with the existing BK transformer, the utility model has the advantages of small size, light weight, safe wiring, and beautiful appearance.
Description
The utility model relates to small-sized dry-type transformer, refers in particular to control or the small-sized dry-type transformer of illumination.
" dry-type transformer " (ZL93234134 stops) is made up of iron core, winding coil, housing, it is characterized in that being filled with heat-conducting medium in the contact portion of iron core and housing." mining GENERAL TYPE dry-type transformer " (ZL97205131), " a kind of dry-type transformer " (ZL98234678) etc. all do not relate to the improvement of the mode of connection in the dry-type transformer.
At present, control or illumination constitute i.e. employing screw and packing ring crimping martingale on the plastics terminal block with the connector assembly of the BK serial transformer in the small-sized dry-type transformer by plastics terminal block and terminal screw and packing ring.Though the JBK serial transformer adopts welding manner, terminal block does not prevent the accidental protector that touches electrified body because of terminal screw and weld tabs position, and electricity consumption is very dangerous, and electrical wiring is also unreliable.
The purpose of this utility model is to overcome above-mentioned defective of the prior art, provides a kind of control or illumination to use small-sized dry-type transformer, and its easy-to-connect is firm, good looking appearance, and Electrical Safety is reliable.
For achieving the above object, the solution that the utility model is taked is: a kind of control or the small-sized dry-type transformer of illumination, comprise iron core, coil, angle Support, connector assembly, connector assembly is made of junction block, weld tabs, terminal screw and packing ring, backplate, cover plate, some grid-like binding posts are arranged in order to weld tabs and terminal screw and packing ring to be installed on the junction block, next side of junction block has backplate to protect weld tabs, has cover plate to protect binding post on the junction block.
Because the utility model adopts the termination of aforesaid way, the grid-like binding post of using for wiring is arranged on the junction block, make the insulation between weld tabs and terminal screw and the packing ring very reliable, and simplified the assembling formality, saved metal corner fittings has been installed; Backplate protects weld tabs and prevents the accidental weld tabs that touches, and cover plate protects binding post and prevents to touch terminal screw and packing ring accidentally, and Electrical Safety is reliable.
Below in conjunction with embodiment and accompanying drawing thereof the beneficial effect of the utility model and generation thereof is remake description.

Fig. 7 is the A-A cutaway view of Fig. 5.
As depicted in figs. 1 and 2, a kind of control or the small-sized dry-type transformer of illumination, comprise iron core (6), coil (7), angle Support (1), connector assembly (12), the mid-coil of iron core (6) (7), following both sides are used screw (2), packing ring (3) and nut (5) fixed bend corner fittings (1) respectively, in order to prevent the leakage field loop, reduce loss, a red steel paper insulation cushion (4) is arranged under packing ring (3); Both sides are used screw (2), packing ring (3), red steel paper insulation cushion (4) and nut (5) link assembly (12) respectively on iron core (6), and the incoming line of coil (7) and output line are welded on respectively on the weld tabs (9) in the connector assembly (12) separately.
As Fig. 3～shown in Figure 7, connector assembly (12) is made of junction block (10), weld tabs (9), terminal screw and packing ring (13), backplate (8), cover plate (11), some grid-like binding posts are arranged in order to weld tabs (9) and terminal screw and packing ring (13) to be installed on the junction block (10), junction block (10) one sides have backplate (8) to protect weld tabs (9), have cover plate (11) to protect binding post on the junction block (10).
As shown in Figure 4 and Figure 5, cover plate (11) is transparent, is convenient to observe the wiring situation of binding post, and can freely dismantles.
As shown in Figure 4, backplate (8) card hangs on the junction block (10), is convenient to dismounting.
As shown in Figure 4, weld tabs (9) is 7 shapes, for hook-type, imbeds in the binding post on the junction block (10) down.Coil (7) incoming line or output line weld after on the hook of weld tabs (9), and wiring is very reliable.
In the utility model, iron core (6) is used the high-quality cold-reduced silicon sheet, this novel connector assembly of adapted (12), and the utility model is than existing BK or JBK serial transformer volume is little, in light weight, profile is more attractive in appearance.
