Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
The first embodiment is as follows:
the special-shaped copper tube provided by the embodiment comprises a hollow tube 1, and a contact end 2 and an insertion end 3 which are respectively arranged at two ends of the hollow tube 1, wherein the hollow tube 1, the contact end 2 and the insertion end 3 are all hollow; the contact end 2 comprises a welding part 4, an anti-reverse-tin part 5 and a first funnel part 6 which are connected in sequence, one end of the welding part 4 is a welding surface 7, the other end of the welding part 4 extends upwards to form the anti-reverse-tin part 5, the first funnel part 6 and one end, connected with the anti-reverse-tin part 5, of the first funnel part are used for blocking the solder from moving upwards, and the other end of the first funnel part 6 is connected with the hollow pipe 1. Further, a second funnel part 8 is arranged at the connection end of the welding part 4 and the solder falling prevention part 5. The height of the solder trap prevention portion 5 in the present embodiment is preferably within a range of (0.34mm, 0.4mm), but is not limited to this range, and may be determined in accordance with actual circumstances.
Specifically, as shown in fig. 3, in the present embodiment, a structure that the solder-tilting prevention portion 5 is perpendicular to the soldering portion 4 is described as an example, a corner between the first funnel portion 6 and the solder-tilting prevention portion 5 is formed to be 90 degrees, and the other end of the soldering portion 4 extends upward to form the solder-tilting prevention portion 5, and the solder-tilting prevention portion 5 has a certain height, so that when the circuit board is soldered in the present embodiment, the solder-tilting prevention portion 5 has a certain height, and therefore is not easy to rise, and if some solder moves upward along the inner wall of the solder-tilting prevention portion 5 and moves to the corner formed by the solder-tilting prevention portion 5 and the first funnel portion 6, the solder is also blocked by the first funnel portion 6, and is difficult to move upward, so that the solder can be effectively blocked from moving upward by the cooperation between the solder-tilting prevention portion 5 and the first funnel portion 6. In the present embodiment, the soldering surface 7 of the contact end 2 is soldered to the circuit board, as shown in fig. 1, and the external pin header or other connector is inserted into the hollow tube 1 through the insertion end 3.
In the special-shaped copper pipe provided by this embodiment, as shown in fig. 4, the cross-sectional shape of the anti-flowing back portion 5 is a circular ring. Specifically, the anti-solder-reflow portion 5 of the present embodiment has a circular ring shape, which helps to increase the area for preventing solder-reflow.
In the copper pipe shaped according to the present embodiment, as shown in fig. 3, a third funnel portion 9 is disposed between the insertion end 3 and the hollow pipe 1. Specifically, the third funnel part 9 is arranged to enable the insertion port of the insertion part to form a guiding inclined plane, so that connecting pieces such as a pin header and a square needle can enter the hollow tube 1 under the guiding effect of the inclined plane, and the situation that the pin header and the square needle are difficult to insert into the hollow tube 1 is avoided.
In addition, the welding surface 7 of the present embodiment is preferably provided as a flat surface, which can reduce the occurrence of the false welding.
In the special-shaped copper tube provided by the embodiment, the insertion end 3, the hollow tube 1, the first funnel part 6, the anti-reverse tin part 5 and the welding part 4 are all integrally formed. That is to say, the special-shaped copper pipe of this embodiment is integrated into one piece, can reduce the condition that each junction appears the chap.
Example two:
in the special-shaped copper tube provided by this embodiment, as shown in fig. 5, a corner angle formed between the anti-flowing-back portion 5 and the first funnel portion 6 is smaller than 90 degrees. That is, the solder trap preventing portion 5 of the present embodiment is not disposed perpendicular to the soldering portion 4, and the soldering portion 4 extends obliquely upward to form the solder trap preventing portion 5. Similarly, when the solder moves upward, the solder is blocked by the first funnel 6 and is less likely to enter the hollow tube 1. In the actual production setting, the angle of the corner between the tin falling prevention part 5 and the first funnel part 6 cannot be too small.
Example three:
in the special-shaped copper tube provided by this embodiment, as shown in fig. 6, a corner angle formed between the anti-flowing-back portion 5 and the first funnel portion 6 is greater than 90 degrees and smaller than 180 degrees. Different from the second embodiment, the angle of the soldering portion 4 extending upwards is different, so that the inclination angle of the anti-flowing-back portion 5 is different, the angle between the anti-flowing-back portion 5 and the first funnel portion 6 can be larger than 90 degrees, and the movement of the soldering tin is blocked by the inner wall of the anti-flowing-back portion 5 and the inner wall of the first funnel portion 6. In addition, during actual production, the rotation angle between the solder tilting prevention part 5 and the first funnel part 6 cannot be too large, so that the situation that the solder cannot be blocked from moving is avoided.
Example four:
in the shaped copper tube provided by this embodiment, as shown in fig. 7, the cross-sectional shape of the anti-flowing back portion 5 is an irregular shape. As shown in fig. 8, the shaped solder trap prevention portion 5 may be shaped like a "flower", or may be shaped like another curved surface as long as the solder trap prevention portion 5 is perpendicular to the soldering portion 4 in the vertical direction.
Example five:
in the special-shaped copper tube provided by the embodiment, the inserting end 3 and the contact end 2 are symmetrically arranged at two ends of the hollow tube 1. As shown in fig. 9, when the inserting terminal 3 has the same structure as the contact terminal 2, the worker does not need to distinguish the welding direction of the special-shaped copper tube during welding, and any direction can be welded on the circuit board, so that the use is more convenient.
The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
