Description

Technical Field

[0001] The utility model relates to the technical field of pins, in particular to a special-shaped pin with firm welding. Background Technique

[0002] A special-shaped pin is a specially designed pin with a non-traditional and irregular shape to meet specific connection or transmission requirements. It is usually used to connect important components with irregular curved surfaces and multi-faceted surfaces in complex equipment.

[0003] Existing special-shaped pins are usually fixed by soldering. However, the welding part of the special-shaped pin has a small size and a relatively smooth surface, making it difficult to fully combine with the solder, resulting in insecure welding. Content of the Utility Model

[0004] The purpose of the utility model is to provide a special-shaped pin with firm welding to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A special-shaped pin with firm welding, including a pin main body, pin parts and welding parts respectively arranged at both ends of the pin main body, and a bending part arranged on one side of the pin main body. Grooves are symmetrically arranged on both the upper and lower sides of the welding part. The inner walls of two grooves on the same side are respectively fixedly connected with a plurality of first inclined blocks and second inclined blocks arranged at equal distances. A first inclined surface is arranged on one side of the first inclined block, and a second inclined surface is arranged on one side of the second inclined block, and the orientations of the first inclined surface and the second inclined surface are opposite. A plurality of protrusions are arranged on both the left and right sides of the welding part.

[0006] As a preferred scheme of the utility model, the protrusion is of a hemispherical structure.

[0007] As a preferred scheme of the utility model, chamfers are arranged at the edges of the grooves.

[0008] Compared with the prior art, the beneficial effects of the utility model are: The first inclined block, the second inclined block, the grooves and the protrusions arranged in the utility model can all increase the contact area between the welding part and the solder, enabling the welding part to better combine with the solder, thus making the special-shaped pin firmly welded.

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a special-shaped pin with firm welding, including a pin body 1, a pin part 2 and a welding part 4 respectively arranged at both ends of the pin body 1, and a bending part 3 arranged on one side of the pin body 1. Grooves 5 are symmetrically arranged on both the upper and lower sides of the welding part 4. The grooves 5 can increase the contact area between the welding part 4 and the solder, making the welding more firm. And the grooves 5 can accommodate the first inclined block 8 and the second inclined block 9, so that the first inclined block 8 and the second inclined block 9 do not protrude from the surface of the welding part 4, thereby avoiding the inclination of the welding part 4 during welding and affecting the welding effect. The inner walls of the two grooves 5 on the same side are respectively fixedly connected with a plurality of first inclined blocks 8 and second inclined blocks 9 arranged at equal distances. The first inclined block 8 and the second inclined block 9 are combined with the solder to increase the contact area between the welding part 4 and the welding, so that the welding is more firm. One side of the first inclined block 8 is provided with a first inclined surface 10, and one side of the second inclined block 9 is provided with a second inclined surface 11, and the orientation of the first inclined surface 10 is opposite to the orientation of the second inclined surface 11. The opposite setting of the orientation of the first inclined surface 10 and the orientation of the second inclined surface 11 can make the second inclined block 9 and the first inclined block 8 more firmly combined with the solder. A plurality of protrusions 6 are arranged on both the left and right sides of the welding part 4. The protrusions 6 can also increase the contact area between the welding part 4 and the welding, further making the welding part 4 firmly welded.

[0016] Among them, the protrusion 6 is of a hemispherical structure, and the hemispherical structure makes the solder more easily coated on the outside of the protrusion 6.

[0017] Among them, a chamfer 7 is provided at the edge of the groove 5, and the chamfer 7 is used to guide the solder to make the solder more easily enter the groove 5.

[0018] Specifically, during welding, the solder will flow into the groove 5 to combine with the first inclined block 8 and the second inclined block 9, and the solder will also combine with the protrusion 6, greatly increasing the contact area with the welding, thereby making the welding of the special-shaped pin more firm.
