[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0038] Unless otherwise stated, the term "multiple" means two or more.

[0039] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0040] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0042] Combination Figures 1 to 4 As shown in the figure, an embodiment of this disclosure provides a pin connector assembly, including a plurality of regularly arranged pins, the pins being bent; it also includes: a first pre-fixing body 20, which has a plurality of first pin holes 201 for mounting the first pin feet 101 of the pins; and a second pre-fixing body 30, which has a plurality of second pin holes 301 for mounting the second pin feet 102 of the pins; wherein, the bottom wall of the first pre-fixing body 20 extends outward to form a positioning post 202 for positioning and assembly.

[0043] The pin connector assembly provided in this embodiment features multiple regularly arranged and bent pins that are installed in conjunction with corresponding pin holes on the first pre-fixed body 20 and the second pre-fixed body 30. This ensures a more stable and orderly installation of the pins, guaranteeing the stability of the electrical connection. The first pre-fixed body 20, the second pre-fixed body 30, and the pins are assembled to form a relatively independent connector assembly, facilitating subsequent assembly and solving the problems of positioning, fixing, and manually assembling pins individually within the mold cavity. Furthermore, the positioning post 202, which protrudes outward from the bottom wall of the first pre-fixed body 20, is used for positioning and assembly, improving the installation accuracy and efficiency of the assembly within the overall device, reducing deviations and errors during installation, and ensuring accurate docking of the pin connector assembly with other components.

[0044] In the manufacturing process of electronic devices, the pin connector assembly is a critical connecting component, and its stability and installation accuracy are paramount. The regular arrangement of multiple pins can meet the signal transmission needs of different circuits, while the bent configuration can be flexibly adjusted according to the internal space layout of the equipment, effectively utilizing space. The pinhole design of the first and second pre-fixed bodies prevents the pins from shaking or shifting after installation, ensuring the stability of current or signal transmission between the pins and reducing the risk of signal interference and transmission loss. Furthermore, as a relatively independent component, the connector assembly allows the pins to be assembled independently without relying on a mold, facilitating automated assembly and improving production efficiency; it also solves the problems of positioning, fixing, and manually assembling pins within the mold cavity, simplifying the mold structure.

[0045] The presence of the positioning post 202 allows for rapid guidance of the pin connector assembly and the parts to be assembled to be accurately installed in the designated positions during assembly, saving assembly time and improving production efficiency, especially suitable for large-scale production scenarios. At the same time, high-precision positioning assembly reduces equipment failures caused by installation deviations, improving the overall quality and reliability of the product.

[0046] The existing injection molding method for pins and connector housings involves fixing and positioning each pin inside the mold. This results in a complex mold structure, a large mold volume, and reduced injection molding efficiency.

[0047] In this embodiment, before injection molding, the first pre-fixed body 20, the second pre-fixed body 30, and the pin are pre-assembled to form a relatively independent connector assembly. Then, the connector assembly is fixed in the mold, and the mold is closed for injection molding. This eliminates the need to individually place and fix the pins in the mold, simplifying the mold structure and improving assembly efficiency. As a relatively independent component, the connector assembly allows the pins to be assembled independently without relying on the mold, facilitating automated assembly and improving production efficiency. It also solves the problems of positioning, fixing, and manually assembling pins individually within the mold cavity.

[0048] Optionally, the first pre-fixed body 20 is interference-fitted with the pin; and / or, the second pre-fixed body 30 is interference-fitted with the pin.

[0049] The interference fit enhances the connection strength between the pin and the first pre-fixed body 20 and / or the second pre-fixed body 30, making the pin less prone to loosening or falling off during long-term use. This further improves the reliability and stability of the pin connector assembly and extends the service life of the assembly.

[0050] In practical applications, electronic devices may be affected by various factors such as vibration, impact, and temperature changes. The large frictional force generated by the interference fit can effectively resist these external forces, ensuring that the pins remain in the correct position. Taking automotive electronic devices as an example, continuous vibration occurs during vehicle operation. If the pin connection is not secure, poor contact can easily occur, affecting the normal operation of the device. However, with the interference fit, the pins are tightly bonded to the pre-fixed body, which can withstand long-term vibration and ensure the continuity and stability of signal transmission. In addition, the interference fit can also prevent dust, moisture, and other impurities from entering the connection gap between the pin and the pre-fixed body to a certain extent, avoiding component damage caused by corrosion, short circuits, and other problems, thus improving the environmental adaptability and durability of the component.

[0051] Optionally, the positioning post 202 is a columnar structure, a conical structure, or a stepped structure; wherein, when the positioning post 202 is a conical structure or a stepped structure, the cross-sectional area of ​​the lower part of the positioning post 202 is greater than the cross-sectional area of ​​the upper part.

[0052] Different structures of the positioning pins 202 can meet different assembly requirements. The columnar positioning pins 202 are simple to process and easy to manufacture and install; the tapered positioning pins 202 have a self-guiding function when inserted into the positioning hole, which can more conveniently and quickly achieve positioning assembly and improve assembly efficiency; the stepped positioning pins 202 can provide different levels of positioning accuracy at different assembly stages, enhance the positioning effect, and their larger cross-sectional area at the bottom can provide more stable support, further improving the stability of the pin connector assembly after installation.

[0053] In production practice, different equipment has varying assembly requirements for pin connector components. The columnar positioning post 202, due to its regular shape and low processing cost, is an ideal choice for products where assembly precision requirements are not high but cost control is paramount. It can reduce production costs while ensuring basic positioning functionality. The self-guiding function of the conical positioning post 202 is significantly advantageous in automated assembly. When assembled by robots or automated equipment, even with some positional deviation, the conical positioning post 202 can smoothly insert into the positioning hole, reducing debugging time and scrap rate during assembly. The stepped positioning post 202 is suitable for complex equipment with high requirements for assembly precision and stability. For example, in high-end electronic communication equipment, the positioning precision requirements at different stages can be precisely controlled through the stepped structure. The larger cross-sectional area at the bottom enhances the stability of the component after installation, preventing component displacement due to external forces and ensuring long-term stable operation of the equipment.

[0054] When the positioning post is stepped, both the lower step of the positioning post and the support platform have a height limit function. Preferably, the height of the lower step of the positioning post is the same as the height of the support block.

[0055] Optionally, the support block 203 is disposed on the first pre-fixed body 20 and on the same side as the positioning post 202, for supporting the printed circuit board (PCB).

[0056] The support block 203 provides additional support to the printed circuit board (PCB), distributing the support force of the pin connector assembly on the PCB, preventing deformation due to uneven stress, protecting the circuit lines on the PCB, and improving the reliability of the entire circuit system. Simultaneously, the support block 203 and the positioning post 202 are located on the same side, which helps to further improve the overall stability and accuracy of the assembly of the pin connector assembly and the PCB.

[0057] Printed circuit boards (PCBs) are crucial components in electronic devices, integrating numerous electronic components and circuit lines. Deformation of the PCB can lead to connection problems between electronic components, such as short circuits or open circuits, affecting the normal operation of the equipment. The support block 203 effectively prevents this from happening by distributing the pressure on the pin connector assembly, ensuring the PCB remains flat at all times. In precision electronic devices with extremely high requirements for PCB flatness, such as aerospace and high-end medical electronic equipment, the support block 203 plays a particularly critical role. Furthermore, the support block 203 is positioned on the same side as the positioning post 202, providing operators with a clear positioning reference during assembly, facilitating accurate installation of the pin connector assembly and the PCB, reducing assembly errors, and improving assembly efficiency and product quality.

[0058] Optionally, the support block 203 is arranged along the length direction of the first pre-fixed body 20.

[0059] The support block 203, which is arranged along the length of the first pre-fixed body 20, can support the printed circuit board more evenly, further enhance the support effect on the printed circuit board, reduce the possibility of deformation of the printed circuit board due to uneven force at different positions, and thus better protect the printed circuit board and its circuits, ensuring the stable operation of the circuit system.

[0060] For some large printed circuit boards (PCBs), the stress distribution at different locations under the pressure of the pin connector assembly is complex. If the support blocks 203 are not distributed properly, excessive localized deformation of the PCB can easily occur. By placing the support blocks 203 along the length of the first pre-fixed body 20, a uniform support force can be provided across the entire length of the PCB, resulting in a more balanced stress distribution. Taking the motherboard of a large server as an example, its large size and high integration require extremely strict flatness. Using this method of placing the support blocks 203 along the length effectively avoids bending deformation of the motherboard due to uneven stress, ensuring stable transmission of numerous high-speed circuit signals on the motherboard and improving the server's operational stability and reliability. Simultaneously, the uniformly distributed support blocks 203 also reduce the risk of fatigue damage to the PCB due to long-term stress, extending the PCB's lifespan.

[0061] Optionally, the first prefixation body 20 and / or the second prefixation body 30 are made of plastic.

[0062] Plastic materials have advantages such as light weight, low cost, and good insulation performance. The first pre-fixing body 20 and / or the second pre-fixing body 30 are made of plastic, which can reduce the overall weight of the pin connector assembly, reduce production costs, and at the same time, the good insulation performance can effectively prevent short circuits between pins and improve the electrical safety of the assembly.

[0063] With the trend towards miniaturization and lightweighting in electronic devices, reducing component weight is of paramount importance. The use of plastic materials allows for significant weight reduction in pin connector components while maintaining functionality. For example, in wearable electronic devices, lighter components contribute to improved wearing comfort and portability. From a cost perspective, plastic raw materials are relatively inexpensive, and plastic molding processes are mature, effectively reducing material and processing costs in the production process and enhancing product market competitiveness. In terms of electrical performance, the insulating properties of plastic can prevent signal interference between pins, ensuring accurate current or signal transmission. In devices with extremely high electrical safety requirements, such as medical electronic devices and power electronic devices, the insulating properties of plastic pre-fixed bodies can prevent leakage accidents, ensuring user safety and the normal operation of the equipment.

[0064] This disclosure also provides a pin connector, including the pin connector assembly provided in the above embodiments.

[0065] The Pin connector provided in this disclosure includes the Pin connector assembly described above, which inherits its stable electrical connection performance, high-precision positioning and assembly characteristics, and good structural stability. This ensures a reliable electrical connection when the connector is connected to other components, thereby improving the overall performance and reliability of the connector.

[0066] As a relatively independent component, the connector assembly allows the pin to be assembled independently without relying on the mold, which is conducive to automated assembly and improves production efficiency; it solves the problems of positioning, fixing and manually assembling the pin separately in the mold cavity, and simplifies the mold structure.

[0067] In the connection systems of various electronic devices, the pin connector is a key component, and its performance directly affects the operational stability of the equipment. Due to the secure installation of the pins in the pin connector assembly, the precise positioning of the positioning post 202, and the reasonable cooperation between various components, the pin connector can quickly and accurately complete docking when connecting to other device interfaces, reducing errors and poor contact problems during the connection process. For example, in applications such as smartphone charging interfaces and computer external device interfaces, the pin connector, with its stable electrical connection performance, ensures reliable power and data transmission, improving the user experience. At the same time, its excellent structural stability can withstand repeated mating and unmating operations, extending the connector's lifespan and reducing equipment maintenance costs.

[0068] Optionally, the pin connector also includes a housing 40, integrally injection molded with the pin connector assembly.

[0069] The one-piece injection molding process ensures a tight fit between the housing 40 and the pin connector assembly, improving the overall structural strength and stability, reducing assembly gaps between components, and minimizing the risk of dust, moisture, and other impurities entering the connector, thus protecting the internal pins and other components.

[0070] In some embodiments, the housing and the pin connector assembly are detachably connected. This detachable design facilitates connector repair and replacement; when a part of the connector fails, the corresponding component can be disassembled individually for repair or replacement, reducing maintenance costs and equipment downtime, and improving equipment maintainability.

[0071] The existing injection molding method for pins and connector housings involves fixing and positioning each pin inside the mold. This results in a complex mold structure, a large mold volume, and reduced injection molding efficiency.

[0072] In this embodiment, during injection molding, the pin connector assembly is first placed into the mold. At this point, the connector assembly is a relatively independent component, pre-assembling the pins. This eliminates the need to individually place and fix the pins into the mold, simplifying the mold structure and improving assembly efficiency. After assembling the pin connector assembly with the mold, the mold is closed and injection molded. The connector assembly, being a relatively independent component, allows the pins to be assembled independently without relying on the mold, facilitating automated assembly and improving production efficiency. It also solves the problems of positioning, fixing, and manually assembling pins individually within the mold cavity, simplifying the mold structure.

[0073] In industrial production and practical use, equipment reliability and maintainability are crucial considerations. The one-piece injection-molded structure enhances the overall robustness of the pin connector, enabling it to withstand complex working environments. For example, in outdoor electronic equipment, harsh weather conditions can cause dust, rain, and other impurities to corrode the connector. The tightly integrated housing 40 and connector assembly effectively block these impurities, protecting internal precision components and ensuring the connector's normal operation. The detachable connection feature greatly facilitates equipment maintenance. Taking connectors in automotive engine control systems as an example, when a connector malfunctions, maintenance personnel can quickly disassemble the relevant components for inspection and repair, eliminating the need for replacing the entire expensive connector and significantly reducing maintenance costs. Simultaneously, completing repairs quickly reduces vehicle downtime, improving production efficiency and user satisfaction.

[0074] Optionally, the housing 40 includes a body 401 for accommodating the first pre-fixed body 20, wherein the first pre-fixed body 20 abuts against the side wall of the body 401; wherein the first pin 101 of the pin located in the first pre-fixed body 20 is disposed facing the opening of the body 401. This facilitates the installation of the first pin 101 of the connector's pin with other components.

[0075] Optionally, the housing 40 further includes: a plug-in portion 402, which is a hollow structure, located on one side of the main body 401 and connected to the main body 401; wherein, the second pre-fixed body 30 is located in the main body 401 and / or the plug-in portion 402 and abuts against the main body 401 and / or the plug-in portion 402, and the second pin 102 of the pin is located inside the plug-in portion 402.

[0076] The main body 401 and the insertion part 402 of the housing 40 are rationally designed. The way the main body 401 accommodates and abuts the first pre-fixed body 20, and the way the insertion part 402 accommodates and abuts the second pre-fixed body 30, further enhances the stability of the pin connector assembly within the housing 40, preventing displacement or shaking during use. The hollow structure of the insertion part 402 facilitates connection with external devices, provides suitable insertion space for the second pin 102 of the pin, ensures the tightness and reliability of the connector connection with external devices, and guarantees the stability of the electrical connection.

[0077] In practical applications, the stability and tightness of the connector are crucial to equipment performance. The contact method between the main body 401 and the first pre-fixed body 20, and between the insertion part 402 and the second pre-fixed body 30, effectively restricts the movement of the pin connector assembly within the housing 40 by increasing the contact area and friction, ensuring its stability even under external forces such as vibration and impact. For example, in rail transit signaling systems, trains generate strong vibrations during operation; this stable structural design ensures the normal operation of the pin connector and prevents signal transmission interruptions due to loose connections. The hollow structure design of the insertion part 402 optimizes the connection method between the connector and external devices, enabling tight adaptation to various standard interfaces and improving the versatility and reliability of the connection. In the field of consumer electronics, such as mobile phones and tablets, where users frequently plug and unplug external devices, the reasonable design of the insertion part 402 ensures a tight and reliable connection every time, reducing data transmission errors or charging abnormalities caused by poor contact.
