Abstract
The utility model discloses a tool for soldering a magnetic circuit body. The tool comprises an insulating body. Accommodating grooves for accommodating magnetic circuit bodies are formed on the top of the insulating body. A positioning gap is arranged on the circumference of each accommodating groove. The gap of the magnetic circuit body to be soldered and the positioning gap are arranged in same direction. Two clamping elements used for fixing a wire are fixedly connected with the top of the insulating body, and are respectively disposed at the left side and right side of the inward radial direction of the positioning gap of the accommodating groove. The gaps are disposed on the tool such that the gap of the magnetic circuit body to be soldered and the positioning gap are aligned and maintained in same direction, thereby achieving convenient and quick positioning and good product consistency. The two clamping elements fixedly press the wire of the magnetic circuit body such that the wire is maintained right over a bonding pad and is just aligned to and contact the bonding pad when being soldered. The positions, on the bonding pads, of the wires are substantially same. An automatic soldering machine may accurately solder the wires while not needing to find the wires.

Preferably, described two clamping elements are on same the first straightway, described the first straightway is mutually vertical with the diameter that described locating notch radially inwardly forms, and this first straightway drops on the end points of this diameter away from locating notch with the vertical intersection point of diameter, the length of the first straightway is less than or equal to the fixing point distance of lead-in wire from the starting point of magnetic path body to clamping element.Adopt said structure, two lead-in wires after fixing form isosceles triangle with the first straight line, after lead-in wire is fixing, with fully the contacting of pad, guarantee that welding is rear firm.
As a kind of improvement of the present utility model, the side of described clamping element is established 2 reference columns, and the mid point of the magnetic path body breach to be welded in the central point of described 2 reference columns and containing groove drops on respectively on the summit of same equilateral triangle.Said structure is first adjacent to lead-in wire and leans against reference column from the breach direction of magnetic path body, fix with clamping element again, because the breach of 2 reference columns and magnetic path body is respectively on the summit of equilateral triangle, while having guaranteed tension lead-in wire, lead-in wire is adjacent to the center of pad, and it is more accurate to locate.
Concrete, described clamping element is shell fragment, described shell fragment comprise with the planar portions of the upper end laminating of insulating body and with planar portions lacing film portion in an acute angle.By lead-in wire from lacing film portion hang into, make lead-in wire and sandwich between planar portions and insulating body, push down lead-in wire by the elastic force of shell fragment fixing, hang into all easy to operate with taking-up.
As another improvement of the present utility model, on described insulating body, also have the location hole that at least 2 alignment pins that are provided with welding equipment locating platform mate.By location hole, the alignment pin of all the other automatic tin welding machines or the navigation system clamp of streamline are coordinated, guaranteed the direction uniformity of tool, be convenient to automated production.
The utility model has the following advantages and beneficial effect compared to existing technology:
The utility model, by breach being set at tool, makes magnetic path body breach to be welded and its contraposition keep same direction, locates easily and fast good product consistency; Fixedly pushed down respectively the lead-in wire of magnetic path body by two clamping elements, while making to weld lead-in wire remain on directly over pad 3 and just contraposition be adjacent to contact, every lead-in wire position on pad is identical substantially, and automatic tin welding machine, without looking for line, just can be soldered to lead-in wire accurately.
