[0037] Please refer to Figure 1-Figure 7 The pin fixing structure 100 and the charger provided in the embodiment of the utility model can solve the above-mentioned problem, which will be described in detail below.

[0038] refer to Figure 1 The pin fixing structure 100 includes a pin 110, a spring 120, a pressure cover 130 and a shell 140; wherein the pin 110 and the spring 120 are both installed on the pressure cover 130, and the pressure cover 130 is used to be installed on the shell 140, and the pin 110 and the spring 120 are both accommodated in the shell 140.

[0039] During the assembly process of the pin fixing structure 100, the pin 110 and the spring sheet 120 can be first fixed to the pressure cover 130, and then the entire structure of the pressure cover 130, the pin 110 and the spring sheet 120 can be installed into the shell 140, so that the installation of the pin 110 and the spring sheet 120 will not be restricted by the volume of the shell 140, thereby simplifying the assembly steps and reducing the difficulty of assembly.

[0040] refer to Figure 1 and Figure 2 The housing 140 includes a bottom plate 141 and a surrounding plate 142 connected to each other. The bottom plate 141 is used to support the pressure cover 130 . The pins 110 , the springs 120 and the pressure cover 130 are all located on the inner side of the surrounding plate 142 .

[0041] Specifically, one end of the enclosure 142 is connected to the bottom plate 141, and the other end of the enclosure 142 is open, so that the integrated structure after the pin 110, the spring 120 and the pressure cover 130 are assembled can be placed into the inner side of the enclosure 142 from the open end of the enclosure 142, and the bottom plate 141 is used to support the pressure cover 130 to play a limiting role.

[0042] The pin fixing structure 100 also includes a cover 160, which is used to seal the open end of the enclosure 142, so that the cover 160, the enclosure 142 and the bottom plate 141 can form a relatively closed structure to accommodate and protect the internal components and prevent dust, impurities and water droplets from mixing in and affecting the performance of the charger.

[0043] At the same time, the cover 160 may be provided with a plurality of charging interfaces, which are used to correspond to the circuit board module 150 in the housing 140, so as to realize the charging operation. Moreover, the charging interface includes but is not limited to a MicroUSB interface, a USB Type C interface, a Lightning interface, a MiniUSB interface, etc. The specific number of the charging interface may be one, two, four, etc., and the specific type and number of the charging interface are not limited.

[0044] refer to Figure 2-Figure 5 In order to improve the relative position stability between the pressure cover 130 and the bottom plate 141, a first buckle portion 131 may be formed on the pressure cover 130, and a second buckle portion 1411 may be formed on the bottom plate 141. One of the first buckle portion 131 and the second buckle portion 1411 is a buckle position, and the other is a slot, and the buckle position cooperates with the slot.

[0045] In this embodiment, the first snap-fit ​​portion 131 is a buckle position, and the second snap-fit ​​portion 1411 is a slot; of course, in other embodiments of the present invention, the first snap-fit ​​portion 131 can also be a slot, and the second snap-fit ​​portion 1411 can be a buckle position; the first snap-fit ​​portion 131 and the second snap-fit ​​portion 1411 can also both include a slot and a buckle position, and the specific structures of the first snap-fit ​​portion 131 and the second snap-fit ​​portion 1411 are not limited.

[0046] refer to Figure 2-Figure 5 The bottom plate 141 is provided with a positioning rib 1412, which is perpendicular to the surface of the bottom plate 141. The card slot is provided at the positioning rib 1412. By providing the positioning rib 1412, the card slot can have a stronger structural strength, and can be more stably matched with the buckle position, thereby preventing the two from being easily separated. The positioning rib 1412 is limited to be perpendicular to the surface of the bottom plate 141, which can make demoulding easier during the molding process.

[0047] refer to Figure 2-Figure 5 In order to improve the abutting stability of the pressure cover 130 , a supporting rib 1413 may be formed on the bottom plate 141 , and a supporting boss 132 may be formed on the pressure cover 130 , and the supporting boss 132 abuts against the supporting rib 1413 .

[0048] Specifically, the support boss 132 and the first buckle portion 131 on the pressure cover 130 are arranged at two ends of the pressure cover 130 opposite to each other, thereby ensuring that the pressure cover 130 will not be easily deflected when mating with the bottom plate 141 .

[0049] Similarly, in order to reduce the difficulty of demoulding, the supporting ribs 1413 can also be arranged perpendicular to the plate surface of the bottom plate 141.

[0050] refer to Figure 2-Figure 5 In order to facilitate the plugging operation of the plug pin 110, the bottom plate 141 is provided with a movable hole 1414, and the movable hole 1414 is used for the plug pin 110 to pass through.

[0051] At the same time, it is convenient to adjust the real-time status of the pin 110 during use and storage. The pin 110 can be rotatably connected to the pressure cover 130, and a storage groove 1415 is formed on the side of the bottom plate 141 away from the spring 120, so that the pin 110 can be located in the storage groove 1415 in the storage state. The storage groove 1415 protects the pin 110 and prevents the pin 110 from protruding and being easily hit. When in use, force can be applied to the pin 110 so that the pin 110 can be rotated out of the storage groove 1415 for use.

[0052] At the same time, in order to reduce the difficulty of forming, the position of the receiving groove 1415 can be made to correspond to the position of the supporting convex rib 1413. That is, during the forming process, stamping can be performed from the side of the bottom plate 141 away from the spring sheet 120, so that the receiving groove 1415 and the supporting convex rib 1413 can be formed at the same time in one stamping.

[0053] refer to Figure 2-Figure 6 In order to improve the relative position stability between the spring sheet 120 and the pressure cover 130 , a positioning boss 133 may be formed on the pressure cover 130 , and a positioning hole 121 is formed on the spring sheet 120 . The positioning boss 133 is accommodated in the positioning hole 121 and abuts against the supporting rib 1413 .

[0054] In the present embodiment, the number of the positioning bosses 133 and the number of the positioning holes 121 are both two, and the two positioning bosses 133 are respectively accommodated in the two positioning holes 121, thereby preventing the pressure cover 130 and the spring piece 120 from relative deflection; of course, in other embodiments of the present invention, the number of the positioning bosses 133 and the positioning holes 121 can also be three, four, six groups, etc., and there is no limitation on the specific number of groups of the two.

[0055] Moreover, the cross-sections of the positioning boss 133 and the positioning hole 121 are both circular; in other embodiments of the present invention, the cross-sections of the positioning boss 133 and the positioning buckle can also be other shapes such as rectangle, triangle, prism, etc., and there is no limitation on the specific cross-sectional shapes of the two.

[0056] refer to Figure 1 and Figure 7 The pin fixing structure 100 further includes a circuit board module 150. A clamping groove 122 is formed on the spring sheet 120. The clamping groove 122 is used to clamp the circuit board module 150. The side of the pressure cover 130 away from the pin 110 is used to abut against the circuit board module 150. In addition, a slide rail 1421 can be formed on the side wall of the enclosure 142, and the circuit board module 150 and the slide rail 1421 are slidably matched.

[0057] Specifically, the spring 120 is connected between the circuit board module 150 and the plug pin 110 to perform a power conduction function.

[0058] During the assembly process, after the gland 130 is installed in place, the circuit board module 150 can be loaded from the open end of the enclosure 142, and the circuit board module 150 is guided by the slide rail 1421, so that the circuit board module 150 moves along the slide rail 1421 to approach the gland 130, until one section of the bottom end of the circuit board module 150 abuts against the gland 130, one section is embedded in the clamping groove 122, and the other section abuts against the bottom plate 141, thereby completing the installation of the circuit board module 150. After the circuit board module 150 is loaded, the cover 160 is used to seal the open end of the enclosure 142.

[0059] The charger includes a pin fixing structure 100 , a charging cable and an interface socket. The interface socket is installed on a circuit board module 150 . The charging cable is electrically connected to the circuit board module 150 . The charger has all the functions of the pin fixing structure 100 .

[0060] In summary, the pin fixing structure 100 and the charger provided by the embodiment of the present utility model have at least the following advantages:

[0061] (1) During the assembly process of the pin fixing structure 100, the pin 110 and the spring sheet 120 can be first fixed to the pressure cover 130, and then the entire structure of the pressure cover 130, the pin 110 and the spring sheet 120 can be installed into the shell 140, so that the installation of the pin 110 and the spring sheet 120 will not be restricted by the volume of the shell 140, thereby simplifying the assembly steps and reducing the difficulty of assembly.

[0062] (2) A first buckle portion 131 is formed on the pressure cover 130, and a second buckle portion 1411 is formed on the bottom plate 141. One of the first buckle portion 131 and the second buckle portion 1411 is a buckle position, and the other is a slot. The buckle position cooperates with the slot to improve the relative position stability of the pressure cover 130 and the bottom plate 141.

[0063] (3) By forming a positioning rib 1412 on the bottom plate 141 and opening the card slot on the positioning rib 1412, the card slot has a stronger structural strength and can be more stably matched with the buckle position, thereby preventing the buckle connection between the two from being easily broken;

[0064] (4) By forming a supporting rib 1413 on the bottom plate 141 and a supporting boss 132 on the gland 130, the supporting boss 132 abuts against the supporting rib 1413, thereby improving the abutting stability of the bottom plate 141 against the gland 130;

[0065] (5) By running the slide rail 1421 on the side wall of the enclosure 142, the slide rail 1421 guides the circuit board module 150, so that the circuit board module 150 moves along the slide rail 1421 and approaches the pressure cover 130 until it reaches the assembly position, thereby reducing the difficulty of assembling the circuit board module 150.

[0066] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
