[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "objective," and the like in the specification, claims, or accompanying drawings are used to distinguish similar objects and are not necessarily intended to describe a specific sequence or precedence.

[0024] This embodiment of the utility model includes: a base, the base comprising a main body and a first connector, the first connector being integrally formed on the lower side of the main body and extending through the through hole, the outer surface of the base being soldered to the first circuit board; and a second connector being mounted on the upper side of the base and inserted into the port. According to the technical solution of this embodiment, the integrally formed base can reduce the number of parts and assembly steps, and facilitate perforation reflow soldering.

[0025] Reference Figure 1 and Figure 2 , the floating terminals are respectively connected to the first circuit board and the terminals, the first circuit board is provided with a through hole, the terminals are mounted on the second circuit board, and the terminals are provided with a port. The male pin structure provided in this embodiment includes:

[0026] The base 400 includes a main body 410 and a first connector 420 . The first connector 420 is integrally formed on the lower side of the main body 410 and is disposed in a through hole. The outer surface of the base 400 is soldered to the first circuit board.

[0027] The second connecting body 100 is installed on the upper side of the base 400 and is inserted into the port.

[0028] It should be noted that the base 400 and the second connector 100 are both made of conductive materials, and a certain floating gap is set between the base 400 and the second connector 100, which provides a structural basis for the left and right floating during the assembly process of the first circuit board and the second circuit board. During the reflow soldering process, the first connector 420 and the main body 410 are both welded to the first circuit board, and the outer surface of the base 400 is welded to the first circuit board to realize the electrical connection between the base 400 and the first circuit board.

[0029] It should be noted that the integrally formed first connector 420 can reduce the number of components of the male pin structure, thereby reducing assembly steps and facilitating subsequent perforation reflow soldering.

[0030] It should be noted that the terminal can be a floating terminal with a port, or a conventional terminal structure with a port, and the first circuit board and the second circuit board are connected through the terminal and the male pin structure to achieve through-hole reflow soldering.

[0031] It should be noted that a cover plate can be provided, the first connector 420 of the base 400 is connected to the first circuit board, and the second connector 100 is connected to the second circuit board. The cover plate is used to fix the second connector 100 on the upper side of the base 400, and the base 400 is abutted against the second connector 100, and a floating connection between the circuit boards is realized through the male pin structure and the terminal.

[0032] It should be noted that the diameter of the first connector 420 should be smaller than or equal to the diameter of the main body 410 , thereby reducing the size of the opening of the first circuit board.

[0033] It should be noted that, during implementation, multiple male pin structures and terminals can exist between the first and second circuit boards. Align the through-holes of the first circuit board with the first connector 420, insert the first connector 420 into the through-hole, and connect the first connector 420 to the first circuit board. Align the second connector 100 with the port, insert the second connector 100 into the port, and connect the second connector 100 to the second circuit board via the terminal. The cover secures the second connector 100 to the upper side of the base 400. The male pin structure provided in this embodiment, through the integrally formed base 400, reduces the number of parts and thus the number of assembly steps, facilitating installation of the first circuit board and the second connecting plate.

[0034] In addition, in one embodiment, referring to Figure 2 The second connecting body 100 includes a first connecting part 110, a second connecting part 120, a third connecting part 130 and a base 140 distributed from top to bottom and formed in one piece. The upper surface of the first connecting part 110 is a curved surface, the second connecting part 120 is a column, and the upper side of the third connecting part 130 is wider than the lower side.

[0035] It should be noted that the second connector 100 is an integrally formed structure, thereby reducing the number of parts of the male pin structure, reducing assembly steps, and facilitating production.

[0036] It should be noted that a cover plate can be provided. In order to facilitate the cover plate to fix the second connecting body 100 to the base 400, the upper side of the third connecting part 130 is wider than the lower side, and the longitudinal section edge of the third connecting part 130 is curved to prevent the cover plate from falling out between the second connecting body 100 and the base 400. The diameter of the base 140 is larger than the diameters of the first connecting part 110, the second connecting part 120 and the third connecting part 130, so that the cover plate can press the base 140 to the base 400 to achieve the purpose of pressing the second connecting body 100 to the base 400.

[0037] It should be noted that the first connecting portion 110 is aligned with the port, and the second circuit board is installed on the second connecting body 100 through the terminal; the first connecting portion 110 with a curved upper surface can provide positioning for the port without damaging the terminal.

[0038] In addition, in one embodiment, referring to Figures 1 to 3 A groove 411 is provided on the upper side of the main body 410 , the base 140 abuts against the groove 411 , and a tapered groove 413 is provided on the lower side of the groove 411 .

[0039] It should be noted that the bottom of the base 140 abuts against the bottom of the groove 411 , and the groove 411 provides horizontal limitation for the base 140 to prevent the second connector 100 from falling off the base 400 .

[0040] It should be noted that during the actual production process of the base 400, a lathe is used to machine the base 400 to form the groove 411. After the groove 411 is machined, due to various factors in the actual production process between the lathe and the workpiece, a central bump may be generated in the central area of the bottom of the groove 411. To prevent damage to the base 140 caused by the central bump, a tapered groove 413 is machined at the bottom of the groove 411 to eliminate the central bump.

[0041] In addition, in one embodiment, referring to Figure 1 and Figure 2 , also includes a cover plate 200, the cover plate 200 is arranged on the upper side of the base 140, and a receiving space 500 is formed between the lower side of the cover plate 200 and the base 140; a spring 300, the spring 300 is installed in the receiving space 500, and the spring 300 abuts against the cover plate 200 and the base 140.

[0042] It should be noted that the cover plate 200 and the spring 300 are used to press the base 140 against the groove 411 . There is a certain gap between the cover plate 200 and the second connector 100 , which provides a structural basis for subsequent reflow soldering.

[0043] It should be noted that the spring 300 is made of a conductive material. During implementation, if shaking occurs between the base 400 and the second connector 100, the spring 300 is squeezed and elastically deformed, providing elastic force for the base 400 and the second connector 100, thereby maintaining a stable connection between the base 400 and the second connector 100; and the spring 300 is always in contact with the cover 200 and the base 140, and the cover 200 is in contact with the base 400, so that the base 400 and the second connector 100 maintain an electrical connection.

[0044] In addition, in one embodiment, referring to Figures 1 to 3A boss 412 extending inward is provided at the bottom of the side of the groove 411 , and the cover 200 abuts against the boss 412 , and the top of the cover 200 is flush with the top of the main body 410 .

[0045] It should be noted that the bottom of the cover 200 abuts the top of the boss 412, which provides support for the cover 200 and prevents it from rocking. The boss provides the structural foundation for the receiving space 500 formed between the cover 200 and the base 140. The receiving space 500 is of a fixed size and is where the spring 300 is installed.

[0046] It should be noted that the top of the cover 200 is flush with the top of the main body 410, so that the second circuit board installed on the second connector 100 can simultaneously abut against the cover 200 and the main body 410. The support force on the second circuit board is stable, the second circuit board and the male pin structure remain stable, and no shaking occurs between the second circuit board and the male pin structure.

[0047] In addition, in one embodiment, referring to Figures 1 to 3 The longitudinal section of the cover plate 200 is polygonal, the upper side of the cover plate 200 is shorter than the lower side, and the side of the cover plate 200 close to the third connection portion 130 is parallel to the third connection portion 130 .

[0048] It should be noted that the longitudinal section edge of the third connection portion 130 is curved, and the cover plate 200 with a polygonal longitudinal section prevents the base 140 from slipping out of the groove 411 , thereby making the cover plate 200 more effective in fixing the second connection body 100 .

[0049] In addition, in one embodiment, referring to Figures 1 to 3 , the spring 300 is a wave spring 300 .

[0050] It should be noted that the wave spring 300 is compact and made of conductive material. It serves to stabilize the electrical connection. If the base 400 and second connector 100 shake, causing the second connector 100 to detach from the base 400, this could affect the proper functioning of the two circuit boards. The wave spring 300 is designed to withstand axial compression. When the base 400 and second connector 100 shake, the fixed size of the receiving space 500 causes the wave spring 300 to elastically deform under compression. The wave spring 300 and the cover 200 work together to press the base 140 against the groove 411, ensuring the stability of the male pin connection.

[0051] In addition, in one embodiment, referring to Figure 1 and Figure 2 , the bottom edge of the first connecting body 420 is chamfered.

[0052] It should be noted that the chamfered first connector 420 can serve as a positioning guide for the through holes of the first circuit board when the first circuit board is mounted on the first connector 420 , and prevent the first connector 420 from damaging the first circuit board.

[0053] In addition, in one embodiment, referring to Figures 1 to 3 , the diameter of the first connecting body 420 is smaller than the diameter of the main body 410 .

[0054] It should be noted that the diameter of the first connector 420 is smaller than the diameter of the main body 410 , and the first circuit board is mounted on the first connector 420 , thereby reducing the opening size of the first circuit board.

[0055] It should be noted that the through-holes of the first circuit board are aligned with the first connector 420, and the first circuit board is mounted on the first connector 420. The terminals are aligned with the second connector 100, and the second circuit board is connected to the second connector 100 via the terminals. The second connector 100 is mounted in the groove 411 of the base 400, the wave spring 300 is mounted on the upper side of the base 140, and the cover 200 is mounted on the boss 412. The cover 200 and the wave spring 300 jointly press the second connector 100 against the base 400. The male pin structure of this embodiment and the integrally formed base 400 can reduce the number of parts and assembly steps, and facilitate perforation reflow soldering.

[0056] In addition, an embodiment of the present invention further provides a floating terminal, including the above male pin structure.

[0057] It should be noted that the floating terminal can be a male pin structure itself, or can be other devices using a male pin structure. This embodiment does not limit the specific type of the floating terminal, as long as the above male pin structure can be used.
