Furthermore, the connection part of the wedge hole and the jack is an arc-shaped hole.
Further, the wiring terminal body is in a right-angle Z shape.
Furthermore, after the wedge is inserted into the wedge hole, the top surface of the wedge is flush with the side wall of the wiring terminal body.
Further, the wedge is electrically connected with the lead through a connecting wire.
Furthermore, the lead comprises two support rods, one support rod is inserted into the jack, and the other support rod is inserted into the wedge hole as a wedge.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. this device is through being provided with a jack on binding post, directly inserts in the jack with transformer coil's lead wire, then compresses tightly binding post rear portion with miniature cold press, with binding post and lead wire cold welding together, and is quick convenient, no longer need the cooling coil, also need not naked light, safety.
2. Through set up the wedge hole that runs through the jack on binding post, insert with the wedge after the lead wire inserts, bend and wedge tight the fixed with the lead wire, then cold pressure welding again avoids the lead wire to break away from the jack, guarantees simultaneously that the lead wire is more firm.
3. The wedge is made into a strip shape, and then the rear end of the wedge and the lead are wound together by using insulating cloth so as to be electrically connected, so that when the lead is broken, the wedge can still continuously conduct electricity.
4. The lead is divided into two parts, one is inserted into the jack and the other is inserted into the wedge hole, so that the fastening is ensured, and meanwhile, the electrical connection is dually ensured.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic view of a usage status structure according to a first embodiment of the present invention.
Fig. 3 is a schematic view of a usage status structure according to a second embodiment of the present invention.
In the figure: 1-a terminal body, 11-a threaded hole, 12-an insertion hole, 13-a wedge hole, 14-an arc hole, 2-a wedge, 3-a lead and 4-a connecting wire.
Detailed Description
The first embodiment is as follows: as shown in fig. 1, the cold-press welding terminal block for the transformer comprises a wedge 2 made of copper and a terminal block body 1, wherein a threaded hole 11 is formed in the front end surface of the terminal block body 1, an insertion hole 12 into which a coil lead is inserted is formed in the rear end surface of the terminal block body 1, a wedge hole 13 into which the wedge 2 is inserted is formed in the side wall of the terminal block body 1, and the wedge hole is perpendicular to the insertion hole and penetrates through the tail end of the insertion hole.
In this embodiment, the connection between the wedge hole and the insertion hole is an arc-shaped hole 14.
In this embodiment, the binding post body is right angle Z shape.
In this embodiment, after the wedge 2 is inserted into the wedge hole 13, the top surface of the wedge 13 is flush with the sidewall of the terminal body 1.
When the wiring terminal is used, as shown in fig. 2, the lead 3 is inserted into the insertion hole 12, the front end of the lead 3 naturally bends along the arc-shaped hole and downwards enters the inner end of the wedge hole 13, then the wedge 2 is inserted and knocked flat by the wedge 2, so that the top surface of the wedge 2 is flush with the side wall of the wiring terminal body 1; then, the rear part of the wiring terminal body 1 is pressed by a small-sized cold press, so that the lead 3 and the rear part of the wiring terminal body 1 are cold-welded into a whole.
Example two: as shown in fig. 3, the cold press welding connection terminal for the transformer has the same structural material as the connection terminal body 1 and the lead 3, and the difference is that the rear end of the wedge 2 is electrically connected with the lead 3 through a connection wire 4, and the connection wire 4 and the lead 3 are wound together by using an insulating cloth, so that the connection wire and the lead are electrically connected, and when the lead is broken, the wedge can continue to conduct electricity. Of course, the wedge and the connecting wire are integrally formed.
