Description

Technical Field

[0001] This utility model relates to the field of printed circuit board connection technology, and more specifically, to an aviation socket adapter and electrical connection architecture used in printed circuit boards. Background Technology

[0002] With the rapid development of smart grids, the market demand for FTUs (Feeder Terminal Units) as important equipment in the power grid is showing a continuous growth trend. Modular installation has become the mainstream development trend, which requires the connectors in FTU equipment to be able to be installed on a turntable to meet the development needs of modular layout.

[0003] In existing technologies, the 14-pin connectors widely used in FTU equipment are typically connected to PCB printed circuit boards using a separate soldering method. This method requires operators to solder each pin individually, and because the pins are relatively dense, the soldering process is cumbersome and inconvenient, incurring significant labor costs. Furthermore, it is prone to problems such as cold solder joints and missed solder joints, resulting in a low product yield. Utility Model Content

[0004] To address these issues, this invention provides an aviation socket adapter and electrical connection architecture for use on printed circuit boards, thereby solving the technical problems of cumbersome and inconvenient connector-printed board connection procedures, high costs, and low yield rates in the prior art for modular installation of FTU equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An aviation socket adapter for use on printed circuit boards includes: An insulating base is provided with a base body and a straight needle hole and a bent needle groove located in the base body; Several sets of straight needle holes are distributed in the middle part of the base body, and several sets of curved needle grooves are extended and distributed on the outer side of the base body; Adapter pins include several sets of straight adapter pins and several sets of curved adapter pins; Several sets of adapter straight needles are positioned and assembled in a one-to-one correspondence with several sets of straight needle holes, and several sets of adapter bent needles are positioned and assembled in a one-to-one correspondence with several sets of bent needle slots.

[0006] Based on the above technical solution, the present invention is further described as follows: As a further embodiment of this utility model, Both the adapter straight needle and the adapter curved needle are provided with contact elements; The adapter straight needle is connected to the straight needle hole by an interference fit between its contact and the straight needle hole, and the adapter curved needle is connected to the curved needle groove by an interference fit between its contact and the curved needle groove.

[0007] As a further embodiment of this utility model, The contact element is provided with barbs on its outer periphery; The barbed portion of the adapter straight needle is connected to the straight needle hole with an interference fit, and the barbed portion of the adapter curved needle is connected to the curved needle groove with an interference fit.

[0008] As a further embodiment of this utility model, The spacing between the bent needle slots on the base body is greater than the spacing between the straight needle holes.

[0009] As a further embodiment of this utility model, The plug-in socket is fixedly disposed on the insulating base, and the plug-in socket is provided with mating holes. The number of mating holes is the same as the number of adapter pins, and they are electrically connected in a one-to-one correspondence.

[0010] An electrical connection architecture for use on printed circuit boards includes the aforementioned aviation socket adapter.

[0011] As a further embodiment of this utility model, it also includes a PCB printed circuit board; The PCB printed circuit board is provided with solder joint structures, which are distributed according to the arrangement of the adapter pins in the aviation socket adapter. The adapter pins are welded to the solder joints of the PCB one-to-one.

[0012] As a further embodiment of this utility model, a multi-core connector is also included; The multi-core connector is provided with connection point structures, which are detachably and correctly connected to the mating holes of the plug socket in the aviation socket adapter.

[0015] This utility model has the following beneficial effects: 1. This architecture assembles adapter straight needles and adapter bent needles respectively through the straight needle holes and bent needle holes of the insulating base.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The terms "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides an aviation socket adapter for printed circuit boards, including an insulating base 1, adapter pins 2, and a socket base 3. The insulating base 1 effectively serves as a stable assembly foundation for the adapter pins 2; simultaneously, the differentiated structural design of the adapter pins 2 increases the pin gap, ensuring pressure resistance; furthermore, the socket base 3 enables convenient alignment and insertion with external connectors, significantly improving overall functionality and practicality. Specific settings are as follows: Please refer to Figures 1 to 3The insulating base 1 includes a base body 11, straight pin holes 12, and bent pin slots 13. The base body 11 is the basic load-bearing structure of the insulating base 1. Several sets of straight pin holes 12 and several sets of bent pin slots 13 are formed in the base body 11. The straight pin holes 12 are distributed in the middle part of the base body 11 for positioning and assembling the adapter straight pins 21. The bent pin slots 13 extend and are distributed on the outer side of the base body 11 for positioning and assembling the adapter bent pins 22. The number of straight pin holes 12 and bent pin slots is set according to the number of pins of the multi-core connector 5 to ensure the integrity of signal transmission. The shape of the base body 11 is adapted to the installation space of the PCB printed circuit board 4, so that the aviation socket adapter can be smoothly assembled in the designated position of the PCB printed circuit board 4 without interfering with other components.

[0031] In one optional implementation, the base body 11 is made of insulating material, which may be, but is not limited to, high-strength insulating materials such as epoxy resin and polyamide. Such materials have good insulation performance and mechanical strength, which can effectively isolate the electrical connection between each adapter pin 2, avoid short circuits, and at the same time ensure the structural stability of the insulating base 1 during equipment operation, making it less prone to deformation or damage.

[0032] Please refer to Figure 1 and Figure 4 The adapter pin 2 includes an adapter straight pin 21 and an adapter bent pin 22; wherein, a number of sets of adapter straight pins 21 are positioned and connected to a number of sets of straight pin holes 12 in a one-to-one correspondence, and a number of sets of adapter bent pins 22 are positioned and connected to a number of sets of bent pin slots 13 in a one-to-one correspondence, one end of the adapter straight pin 21 and one end of the adapter bent pin 22 are used to solder to the PCB printed board 4, and the other end of the adapter straight pin 21 and the other end of the adapter bent pin 22 are used to contact and conduct electricity with the multi-core connector 5.

[0033] As a preferred embodiment, please refer to Figure 4 Both the adapter straight pin 21 and the adapter curved pin 22 are provided with contact parts, and the outer side of the contact parts is provided with barbs. The adapter straight pin 21 is connected to the straight pin hole 12 of the base body 11 by interference fit through its contact parts and barbs. The adapter curved pin 22 is connected to the curved pin groove 13 of the base body 11 by interference fit through its contact parts and barbs. This is to significantly improve the stable connection performance between the adapter pin 2 and the insulating base 1, prevent loosening or falling off during insertion and removal, and ensure the overall connection reliability.

[0034] As another preferred embodiment, the distribution spacing of the bent pin slots 13 on the base body 11 is greater than the distribution spacing of the straight pin holes 12. The bending angle of the adapter bent pin 22 is set to an angle that adapts to increase the pin gap. By designing the outer ring adapter pins 2 as adapter bent pins 22, and cooperating with the spacing design of the bent pin slots 13, the gap between the outer ring pins is effectively increased. This avoids the disadvantage that if all are straight pins, the pins will be too densely packed on the PCB, which would prevent the PCB from routing and pose a risk of voltage breakdown. The 14 pins on the PCB will be dispersed, allowing for a larger area for routing. The spacing between the lines is larger, reducing the risk of voltage breakdown and avoiding insufficient voltage withstand performance due to small gaps. This improves the electrical performance stability of the adapter and enhances the overall functional adaptability.

[0035] Please continue to refer to this. Figures 1 to 2 The insertion hole seat 3 is fixedly connected to the insulating base 1. The insertion hole seat 3 is provided with mating holes. The number of mating holes is the same as the number of pins of the adapter pin 2. The mating holes and pins are electrically connected in a one-to-one correspondence. The internal structure of the mating holes can be adapted to the connection point structure of the multi-core connector 5, so that the connection point structure of the multi-core connector 5 can be smoothly inserted into the mating holes and make contact with the adapter pin 2 for conductivity, thereby realizing stable signal transmission and ensuring assembly efficiency.

[0036] like Figures 5 to 8 As shown, this embodiment of the invention also provides an electrical connection architecture for printed circuit boards, including the aforementioned aviation socket adapter, as well as a PCB printed circuit board 4 and a multi-core connector 5, for achieving a stable connection between the PCB printed circuit board 4 and the multi-core connector 5 through the aviation socket adapter; simultaneously, it can utilize a combination of soldering and plugging to form a pre-assembled architecture, effectively simplifying the installation process. The specific settings are as follows: Please refer to Figure 5 and Figure 6 The PCB printed circuit board 4 is provided with solder joint structures, and the distribution of the solder joint structures of the PCB printed circuit board 4 is set according to the arrangement of the adapter pins 2 in the aviation socket adapter. The adapter pins 2 and the solder joint structures of the PCB printed circuit board 4 are connected one-to-one to achieve the pre-welding positioning of the aviation socket adapter corresponding to the PCB printed circuit board 4.

[0037] Please refer to Figure 7 and Figure 8The multi-core connector 5 is provided with connection point structures, and the connection point structures of the multi-core connector 5 are detachably aligned and connected to the mating holes of the socket 3 in the aviation socket adapter. An alignment component 51 is also provided between the multi-core connector 5 and the insulating base 1. Specifically, a positioning groove is provided on one edge of the multi-core connector 5, and a positioning protrusion is provided on one edge of the insulating base 1 corresponding to the base body 11. When the multi-core connector 5 and the socket 3 are aligned and connected, the positioning protrusion and the positioning groove are correspondingly limited and assembled. This allows for faster and more precise alignment of the multi-core connector 5 and the aviation socket adapter, reducing the possibility of pin damage due to insertion deviation, ensuring normal signal transmission, and improving overall functionality and practicality.

[0038] This utility model relates to an aviation socket adapter and electrical connection architecture applied to printed circuit boards. By designing the outer ring solder plate pins of the adapter as bent pins, the gap between the outer ring pins is increased, providing sufficient space for the inner ring pin wiring and ensuring the withstand voltage performance between each point. The barbed structure on the contact element and the interference fit with the insulator achieve stable assembly. The aviation socket adapter is pre-soldered to the PCB printed circuit board 4, and the multi-core connector 5 is connected to the adapter by plugging, which effectively simplifies the installation process, improves the yield rate and maintenance convenience. The overall structure is reasonably designed and can provide stable and reliable connection and signal transmission for FTU equipment, adapting to the development needs of modular installation in smart grids and has broad application prospects.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
