Description
Technical Field
[0001] The utility model relates to the technical field of chargers, and specifically to a PIN folding structure with convenient assembly. Background Art
[0002] With the improvement of living standards, handheld electronic products such as tablet computers, e-books, mobile phones, media players, etc. have become one of the essential items in people's daily lives. Chargers are widely used in modern society. Handheld electronic devices are usually charged through chargers. Chargers provide an interface for handheld electronic devices to connect to a power source and provide reliable direct current for electrical equipment that can store electrical energy.
[0003] In order to achieve the portability and space saving of chargers, the PIN folding foot structure is widely used. However, in the actual assembly process, many inconveniences are faced.
[0004] On the one hand, the design of the PIN folding foot is relatively complex and usually includes multiple moving parts and delicate connection structures. This makes it necessary for workers on the assembly line to spend more time and effort to ensure that each folding foot is correctly installed and folded in place.
[0005] For example, some PIN folding feet of chargers use a combination of springs and buckles to achieve the folding function, but such a complex mechanical structure is prone to problems such as the spring not being installed in place and the buckle getting stuck during assembly, thus affecting the assembly efficiency.
[0006] On the other hand, since the production of chargers is usually large-scale assembly line operation, there are high requirements for assembly speed and accuracy. However, due to the flexibility and mobility of the PIN folding foot, it is difficult to position and fix it in an automated assembly device.
[0007] For example, when using a robotic arm for assembly, the PIN folding foot may deviate in position due to its own elasticity, resulting in the inability to accurately insert into the corresponding jack, and manual intervention and adjustment are required, increasing the assembly time and cost.
[0008] In addition, the PIN folding foot and the elastic piece can also be connected to each other by bolts and assembled inside using bolts. However, bolt connection requires additional operating steps such as aligning the screw holes and tightening the bolts, which will increase the assembly man-hours and thus increase the production cost.
[0009] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0046] Please refer to Figures 1-9 , in the embodiments of the present invention, a PIN folding structure for convenient assembly includes:
[0047] Folding PIN foot assembly 1;
[0048] Shrapnel assembly 2, the shrapnel assembly 2 includes a conductive shrapnel 3 and an encapsulating colloid 4 which are of an integrated structure. A first rotating shaft groove 5 is opened inside the encapsulating colloid 4. The folding PIN foot assembly 1 is rotatably arranged in the first rotating shaft groove 5 and elastically abuts and cooperates with the conductive shrapnel 3;
[0049] Outer shell 6, an assembly position 7 is arranged on one side inside the outer shell 6. The whole of the folding PIN foot assembly 1 and the shrapnel assembly 2 can be slidably fitted into the assembly position 7. A notch 8 for cooperating with the folding PIN foot assembly 1 is opened on the surface of the outer shell 6 corresponding to the assembly position 7.
[0050] In the technical solution of the present invention, the conductive shrapnel 3 and the encapsulating colloid 4 are formed into an integrated shrapnel assembly 2 through a plastic-encapsulation process, and a first rotating shaft groove 5 is opened inside the encapsulating colloid 4. Combined with the assembly position 7 arranged on one side inside the outer shell 6, during the assembly process, first install the folding PIN foot assembly 1 in the rotating shaft 19 groove of the shrapnel assembly 2, and then slide and fit the two as a whole into the assembly position 7 of the outer shell 6, thus completing the assembly;
[0051] In summary, through the integrated structural design of the spring element assembly 2, the conductive spring element 3 can be confined in the encapsulated body 4, without the need for bolt assembly, thereby simplifying the structural components and improving the assembly efficiency and structural stability; through the design of the first rotating shaft groove 5, good rotation support and restriction are provided for the folding PIN foot assembly 1, and the folding PIN foot assembly 1 and the spring element assembly 2 can be slidably fitted in the assembly groove as a whole, thereby simplifying the assembly process, improving production efficiency and reducing production costs; the integrated structure of the spring element assembly 2 and the precise fit of the folding PIN foot assembly 1 in the rotating shaft 19 groove enhance the stability of the overall structure and can effectively reduce failures caused by loose or displaced components during use; the elastic abutment between the folding PIN foot assembly 1 and the conductive spring element 3 can ensure a good and stable electrical connection, reduce poor contact and signal transmission problems, and effectively improve the reliability and efficiency of charging.
[0052] In the embodiment of the utility model, the outer side of the assembly position 7 has an opening 9, and first clamping blocks 10 are arranged on both sides of the opening 9, and second clamping blocks 11 are formed on both sides of the encapsulated body 4, and the first clamping block 10 and the second clamping block 11 are elastically clamped together.
[0053] During the assembly process, the folding PIN foot assembly 1 and the spring assembly 2 as a whole can be slid and embedded roughly horizontally along the direction of the opening 9, and the first snap-fit block 10 at the assembly position 7 is elastically snap-fitted with the second snap-fit block 11 on the encapsulated body 4, thereby completing the fixation of the folding PIN foot assembly 1 and the spring assembly 2 as a whole at the assembly position 7. The operation is simple and easy for operators to get started.
[0054] In the embodiment of the utility model, a contact arc surface and a contact plane are provided between the first clamping block 10 and the second clamping block 11 .
[0055] By setting the abutting arc surface, it is convenient to guide the folding PIN foot assembly 1 and the spring assembly 2 as a whole to enter the assembly position 7, and it is convenient for the first clamping block 10 to perform plastic deformation to achieve the function of giving way. By setting the abutting plane, the folding PIN foot assembly 1 and the spring assembly 2 as a whole are effectively prevented from being separated from the assembly position 7, thereby ensuring the firmness of the connection between the whole and the assembly position 7, thereby effectively avoiding failures caused by loose or shifted components during use.
[0056] In the embodiment of the utility model, an abutment block 12 is provided on the inner side of the assembly position 7 , and the abutment block 12 is used to limit the folding PIN assembly in the first rotating shaft groove 5 .
[0057] Through the provision of the abutting block 12, the abutting block 12 can ensure that the position of the folding PIN component in the groove of the rotating shaft 19 is more accurate and stable, avoiding unnecessary displacement during its use, thereby ensuring the normal operation and stable performance of the charger.
[0058] In the embodiment of the present utility model, a second rotating shaft groove 13 matching the folding PIN foot component 1 is provided on the abutting block 12, and the mating cross-section of the first rotating shaft groove 5 and the second rotating shaft groove 13 is circular or substantially circular.
[0059] The cooperation of the first rotating shaft groove 5 and the second rotating shaft groove 13 provides a more uniform and stable support for the folding PIN foot component 1, enabling it to withstand greater forces and torques during rotation and operation, not being easily deformed or damaged, and the circular or substantially circular mating cross-section enables the folding PIN foot component 1 to rotate more smoothly and flexibly, reducing friction and jamming during the rotation process.
[0060] In the embodiment of the present utility model, limiting ends 14 are formed by extending on both sides of the second rotating shaft groove 13, a limiting groove 15 is provided at the position of the first rotating shaft groove 5 on the encapsulating body 4, and the limiting ends 14 are in plug-in fit with the limiting groove 15.
[0061] Through the plug-in fit of the limiting ends 14 and the limiting groove 15, a clear limiting and positioning effect on the folding PIN foot component 1 is achieved, thereby being able to prevent the folding PIN foot component 1 from accidentally coming out or contacting other components, thereby reducing safety risks such as short circuits and electric leakage, improving the use safety of the charger, and enhancing the reliability and durability of the folding structure of the entire charger.
[0062] In an assembled implementation manner, due to possible interference from the cooperation between the folding PIN foot component 1 and the notch 8, the folding PIN foot component 1 can be first assembled on the abutting block 12, and then the elastic piece component 2 can be slid and embedded in the assembly position 7.
[0063] In the embodiment of the present utility model, through openings 16 are provided on both sides of the first rotating shaft groove 5 on the encapsulating body 4, one end of the conductive elastic piece 3 is embedded in the encapsulating body 4, and the other end of the conductive elastic piece 3 extends to the opening 16 and forms an elastic arm 17 for elastically abutting and cooperating with the folding PIN foot component 1.
[0064] It is understandable that the folding PIN - foot component 1 includes a rotating shaft 19 of an integral structure and PIN - feet 20 fixed at both ends of the rotating shaft 19. The PIN - feet 20 and the rotating shaft 19 can also be formed as an integral body through a plastic - coating process. In the above description, that is, the rotating shaft 19 corresponds to the first rotating - shaft groove 5 and the second rotating - shaft groove 13. The encapsulating body 4 is also provided with a receiving groove 21 corresponding to the PIN - feet 20, and this receiving groove 21 corresponds to the position of the notch 8, so as to facilitate the receiving and unfolding of the PIN - feet 20.
[0065] The design of the elastic arm 17 can provide more stable and effective elastic abutment, ensuring that there is always good contact between the folding PIN - foot component 1 and the conductive elastic sheet 3, and reducing the risk of poor contact. It is understandable that the through - hole 16 is communicated with the receiving groove 21, that is, the design of the through - hole can provide a space for the PIN - feet 20 to rotate, and realize the movable elastic electrical abutment between the elastic arm 17 and the PIN - feet 20.
[0066] Among them, the connecting end of the PIN - feet 20 and the rotating shaft can effectively abut against the outer wall of the first rotating - shaft groove 5 at the through - hole 16, thereby further limiting the rotating shaft 19 within the first rotating - shaft groove 5 and the second rotating - shaft groove 13.
[0067] In the embodiment of the present utility model, the elastic arm 17 is located within the moving track of the folding PIN - foot component 1.
[0068] Through this setting, no matter whether the folding PIN - foot component 1 is in the unfolded or folded state, the elastic arm 17 can keep in contact with it within its moving track, ensuring the continuity and stability of current transmission. At the same time, there is no need for an additional complex structure to ensure the contact between the elastic arm 17 and the folding PIN - foot component 1, reducing the difficulty of design and manufacturing.
[0069] In the embodiment of the present utility model, the folding PIN - foot component 1 presents a folded state and an unfolded state at the notch 8. The elastic arm 17 is bent and inclined, and it has a first abutting end 22 and a second abutting end 23 corresponding to the folding PIN - foot component 1, so as to correspond to the folded state and the unfolded state of the folding PIN - foot component 1 respectively.
[0070] In both the folded and unfolded states, there are corresponding abutting ends to provide stable contact, ensuring the reliability of current transmission in different states. That is, when in the folded state, the first abutting end 22 can ensure the close contact between the PIN - feet 20 component and the conductive elastic sheet 3, avoiding loosening or poor contact; when in the unfolded state, the second abutting end 23 plays the same role.
[0071] The design of the bending inclination setting and the two abutting ends can better adapt to the position and angle changes of the folding PIN foot component 1 in different states, provide appropriate elastic pressure, and at the same time, the bending inclination setting enables the elastic arm 17 to be located within the moving track of the folding PIN foot component 1.
[0072] In the embodiment of the present utility model, the conductive elastic sheet 3 has a wiring terminal 18 extending to the outside of the encapsulating body 4, and the wiring terminal 18 is located at a position close to the notch 8 of the outer shell 6.
[0073] With this setting, the position of the wiring terminal 18 close to the notch 8 of the outer shell 6 makes it more convenient for wire connection. The operator can perform the wiring work more easily, reducing the operation difficulty and time, thus effectively improving the assembly efficiency; and when it is necessary to inspect, repair or replace the wire connection part, since the wiring terminal 18 is relatively exposed and close to the notch 8, it is easier to be touched and operated.
[0074] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
