Technical Field

[0001] This utility model relates to the technical field of precision connectors, and more specifically, to a crimp-type POGOPIN assembly. Background Technology

[0002] POGOPIN is a core component for signal and current transmission in electronic devices. With the continuous expansion of AR glasses product lines, magnetic connectors have become a market hotspot due to their convenient docking advantages.

[0020] Reference Figures 1-6 The image shown is a preferred embodiment of the present invention.

[0021] The press-fit POGOPIN assembly provided by this utility model includes an upper adhesive core 400 and a lower adhesive core 500 distributed vertically. An upper magnet 200 is fixedly arranged on the outer periphery of the upper adhesive core 400, and a lower magnet 700 is fixedly arranged on the outer periphery of the lower adhesive core 500. The upper magnet 200 and the lower magnet 700 are connected vertically by magnetic attraction. The upper adhesive core 400 has a plurality of fixedly arranged upper terminals 300, and the lower adhesive core 500 has a plurality of fixedly arranged lower spring-loaded terminals 600. The plurality of upper terminals 300 and the plurality of lower spring-loaded terminals 600 are connected one-to-one. The upper terminal 300 has an upper spring piece 310 on its top, which is exposed above the upper glue core 400 and the upper magnet 200. The upper spring piece 310 is connected to the upper PCB board 100 by crimping, and the bottom of the upper PCB board 100 is connected to multiple upper spring pieces 310. The lower spring pin terminal 600 has a lower spring piece 610 welded and fixed to its bottom, which is exposed below the lower glue core 500 and the lower magnet 700. The lower spring piece 610 is connected to the lower PCB board 800 by crimping, and the top of the lower PCB board 800 is connected to multiple lower spring pieces 610.

[0022] The aforementioned press-fit POGOPIN assembly, through press-fitting, connects the upper and lower spring contacts 610 to the upper and lower PCB boards 800 (board end), eliminating the need for SMT processes and high-temperature manufacturing. This allows for quick assembly and disassembly, reducing maintenance costs. The lower core 500 (male end) uses a lower spring pin terminal 600, which reduces product weight, lowers electroplating costs, and improves space utilization. Furthermore, it employs a magnetic attraction mechanism, utilizing the principle of like poles attracting and unlike poles repelling to prevent mistaken connection. Strong magnets allow for rapid attraction, ensuring a stable connection.

[0023] Specifically, the upper magnet 200, upper glue core 400, upper terminal 300, and upper PCB board 100 form the female connector.

[0024] Specifically, the lower magnet 700, lower glue core 500, lower spring pin terminal 600, and lower PCB board 800 form a male connector.

[0025] The male and female connectors use magnetic attraction to ensure a stable electrical connection.

[0026] In this embodiment, the adhesive core 400 has multiple recessed mounting grooves 401, in which the upper terminal 300 is mounted. An adhesive hole 402 is formed at the bottom of the mounting groove 401, extending vertically through the adhesive core 400. This allows the mounting grooves 401 to provide precise positioning for the upper terminal 300, preventing displacement and ensuring a neat layout.

[0027] The lower glue core 500 has multiple glue holes 501, which extend vertically through the lower glue core 500. Lower spring-loaded terminals 600 are vertically installed in the glue holes 501. The multiple glue holes 501 correspond one-to-one with the multiple upper glue holes 402. This allows for precise alignment of the upper terminals 300 and lower spring-loaded terminals 600, ensuring reliable circuit connections and adapting to the overall structure, thus facilitating efficient assembly. Specifically, the upper terminal 300 includes a longitudinally arranged longitudinal plate 301 and a transversely arranged transverse plate 302. The bottom of the longitudinal plate 301 is connected to the transverse plate 302, and the bottom of the transverse plate 302 abuts against the bottom of the mounting groove 401. The upper part of the lower spring pin terminal 600 extends through the lower glue hole 501. The top of the lower spring pin terminal 600 has a post 601, which is exposed above the lower glue core 500 and is inserted into the upper glue hole 402, connecting with the horizontal plate 302 on the upper glue hole 402. In this way, the post 601 extends through the lower glue hole 501 and is precisely inserted into the upper glue hole 402, ensuring a reliable connection with the horizontal plate 302 and guaranteeing stable circuit continuity.

[0028] In a preferred embodiment, the longitudinal plate 301 has outwardly protruding inserts 303 on both sides. The inserts 303 are embedded in the sidewalls of the mounting groove 401, and the upper terminal 300 is interference-fitted in the mounting groove 401, so that the upper terminal 300 is fixedly installed in the mounting groove 401. This can firmly fix the upper terminal 300, prevent it from loosening or shifting, and the double fixing structure improves the installation stability of the upper terminal 300, ensuring the reliability of subsequent docking with the lower spring pin terminal 600.

[0029] In a preferred embodiment, the lower spring pin terminal 600 has an expansion ring 602 extending radially outward on its outer periphery. The expansion ring 602 is embedded in the side wall of the lower adhesive hole 501, and the lower spring pin terminal 600 is interference-fitted into the lower adhesive hole 501, thus fixing the lower spring pin terminal 600 in the lower adhesive hole 501. This securely fixes the terminal and prevents displacement; the double fixing structure improves the installation stability of the lower spring pin terminal 600 and ensures the reliability of subsequent docking with the upper terminal 300.

[0030] Specifically, the upper glue core 400 and the upper magnet 200 are interference-fitted, so that the upper magnet 200 is fixedly sleeved on the outer periphery of the upper glue core 400. In this way, the interference fit between the upper glue core 400 and the upper magnet 200 can achieve a stable sleeve of the upper magnet 200 without the need for additional fasteners, simplifying assembly and improving the overall reliability of the female seat.

[0031] Specifically, the lower core 500 and the lower magnet 700 are interference-fitted, so that the lower magnet 700 is fixedly sleeved on the outer periphery of the lower core 500. In this way, the interference fit between the lower core 500 and the lower magnet 700 can achieve a stable sleeve of the lower magnet 700 without the need for additional fixing structures, simplifying the assembly process and improving the overall reliability of the male seat.

[0032] The upper magnet 200 is ring-shaped and arranged around the circumference of the upper core 400; the lower magnet 700 is also ring-shaped and arranged around the circumference of the lower core 500. This creates a uniform annular magnetic attraction surface, which ensures more even force distribution when the male and female connectors are mated.

[0033] The top of the lower adhesive core 500 and the lower magnet 700 enclose an embedding area, while the lower part of the upper adhesive core 400 is exposed below the upper magnet 200 and embedded in the embedding area. The upper adhesive core 400 and the lower adhesive core 500 are arranged vertically at intervals. This provides precise positioning space to ensure proper alignment of the male and female connectors.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
