The bottom edge 13, the soldering terminal 10 is provided with a hollow portion 14 that communicates with the first front view surface 11 and the second front view surface 12 (step S101); a solder member 20 is provided, the solder member 20 has a cladding base portion 21, and the solder The member 20 extends from the covering base 21 to an extending portion 211 (step S103) The extension portion 211 is disposed through the hollow portion 14, and then the bent extension portion 211 is adjacent to one end of the cladding base portion 21, so that the coating base portion 21 is bent along the first front view surface 11, the bottom side 13 and the second front view surface 12. The soldering terminal 10 is covered (step S105); and the bent extension portion 211 is away from one end of the coating base portion 21, so that the extending portion 211 has a hook shape (step S107).

As shown in FIG. 1 , FIG. 3B and FIG. 3C , the covering base 21 of the step S105 further includes a bottom bent portion 212 that passes through the bottom edge 13 and is bent at the bottom edge 13 . The bottom bent portion 212 may further be provided with at least one bottom hollow portion 2120. The purpose of the bottom hollow portion 2120 is to appropriately weaken the structural strength of the bottom bent portion 212, so that the bottom bent portion 212 can be easily formed. However, the bottom bent portion 212 does not necessarily have to be provided with the bottom hollow portion 2120, and therefore can be determined depending on the condition of the solder material 20 itself or the like when performing the hanging method of the present invention.

Preferably, referring to FIG. 1 , FIG. 2B and FIG. 3B , when the bottom bent portion 212 is formed and covered on the soldering terminal 10 , the bottom bent portion 212 can be covered with the bottom edge 13 with a gap or without a gap. Since the side 13 is covered, the covering of the present portion is not limited to the contact with the contact, and the bottom bent portion 212 can be covered by the bottom edge 13 in a gap (without contact).

When the extending portion 211 passes through the hollow portion 14, the one end of the extending portion 211 away from the covering base portion 21 can abut or be fused to the covering base portion 21 to form a hook or ring hook structure, so that the solder member 20 It can be more stably hung on the soldering terminal 10.

The invention also provides a hanging structure of a soldering piece and a soldering terminal, such as 2A and 2B, the mounting structure of the soldering member and the soldering terminal comprises: a soldering terminal 10 and a soldering member 20.

The soldering terminal 10 has a first front view surface 11, a second front view surface 12 and a bottom side 13. The solder terminal 10 is further provided with a hollow portion 14 connecting the first front view surface 11 and the second front view surface 12, and the hollow portion 14 can be used for the mounting of the solder member 20.

The solder member 20 may be any form of solder, preferably a solder strip or a strip of solder. When the solder member 20 is preferably mounted in accordance with the mounting method described above, the solder member 20 is attached to the solder. On the terminal 10, the solder member 20 has a cladding base portion 21, and an extension portion 211 extends from the cladding base portion 21. The cladding base portion 21 is along the first front view surface 11, the bottom edge portion 13 of the solder terminal 10. The two front view faces 12 are bent and covered and attached to the welding terminal 10, and the direction of the biasing force F in the drawing can be used as an illustration, but not limited thereto, and the extending portion 211 is hooked through the hollow portion. 14. It is responsible for making the solder member 20 stably hung on the solder terminal 10.

As described above, the portion of the covering base portion 21 located near the bottom surface 13 of the soldering terminal 10 further includes a bottom bent portion 212, and in particular, the covering base portion 21 is about to be folded from the first front viewing surface 11 of the soldering terminal 10 over the bottom edge. 13 is to reach the vicinity of the bottom edge 13 of the second front view surface 12, and the bottom bent portion 212 is covered by the bottom edge 13.

As shown in FIG. 2B , the bottom bent portion 212 is covered on the bottom edge 13 without any gap, which means that the bottom bent portion 212 is in contact with the bottom edge 13 when covering the bottom edge 13 . Thus, since the solder member 20 and the bottom edge 13 are in contact with each other, the solder member 20 can be more perfectly subjected to the heat transmitted by the solder terminal 10, contributing to the melting of the solder.

In order to make the hanging structure more stable, the extension portion 211 is away from the package. One end of the base portion 21 can abut or be fused to the cladding base portion 21, and in the case of FIG. 2B, an example in which the extension portion 211 is fused to the cladding base portion 21 is shown.

Further, the bottom bent portion 212 may further have a bottom hollow portion 2120.

It can be understood from the present embodiment that the hanging structure of the embodiment has a relatively large cladding base 21, so that when soldering, more and more solder will be provided than the foregoing embodiment, so that a large amount of solder is required in response to the need. Since the volume and the area of the coating base portion 21 are relatively large, the coating base portion 21 may cause difficulty in bending when the bottom edge portion 13 forms the bottom bent portion 212, so that the solder member 20 may be previously used. At least the bottom hollow portion 2120 is disposed in advance at the portion corresponding to the bottom bent portion 212. Thus, the structural strength of the bottom bent portion 212 is slightly weakened, and the hanging structure is smoothly formed.

As shown in FIG. 3B, after the extension portion 211 of the present embodiment forms a hook-like hook structure through the hollow portion 14, the extension portion 211 abuts against one end of the cladding base portion 21, but This is not limited to this method. In addition, the bottom bent portion 212 can also be spaced apart from the bottom edge 13 to allow the relatively large cladding base portion 21 to provide a margin of bending stress during the bending process to avoid breakage. Increase the success rate and stability of the hanging structure.
