[0024] The following description, by way of example, illustrates the structural composition, features, and advantages of the pin header guide plate, electrical connector, and electronic device according to this application. However, it should be understood that all descriptions are not intended to limit the scope of this application. For the sake of simplicity, identical or similar parts and features may be indicated in only one or more places in the same drawing.

[0025] exist Figure 1 The present invention provides only a partial embodiment of an electronic device according to the present application by way of example, wherein an example of a pin header guide plate according to the present application is configured and used in conjunction with pin headers and electronic components. Figure 1 The example is shown in a state of being ready for assembly. When the pin header guide plate and the pin header are connected, an electrical connector can be formed. Figure 1 The electrical connector has been marked with reference numeral 100.

[0026] Specifically, in Figure 1 In the electronic device 200 shown, the pin header 20 can be equipped with multiple pins 21 according to actual application needs, so that various possible signals and data, such as current signals, voltage signals, and control commands, can be transmitted after electrical connection through these pins. Figure 1 As shown, the pin 21 has a first end 211 and a second end (not shown), each extending outward for electrical connection. Any feasible structural configuration can exist between the first end 211 and the second end, such as forming one or more bends, to facilitate overall application layout, for example, in... Figure 1 The example demonstrates that the pins 21 can be extended outward from the housing 22 of the electrical connector 100 and optionally bent at an angle of approximately 90°, thereby facilitating the assembly operation of the pin header 20 with the pin header guide plate 10 and the electronic components 30.

[0027] As described above, the pin header guide plate 10 and the pin header 20 can be assembled together to form an electrical connector 100. For example, it can be assembled and connected to the housing 22 of the electrical connector 100 via any suitable assembly structure 16, such as a snap-fit, provided on the pin header guide plate 10. Such an electrical connector can be manufactured, produced, and sold as a separate product. Figure 1 For example, the first end 211 of the pin 21 in the pin header 20 can be inserted and passed through the corresponding socket 11 on the pin header guide plate 10, and then plugged into the corresponding connector 31 (such as a socket) on the electronic component 30 to form an electrical connection. Figure 7 The example provided illustrates this. The pin guide plate 10 guides and supports the pins 21 in the pin header 20, and in particular, facilitates the electrical connection of these pins 21 to the outside. This not only avoids problems such as misalignment, broken pins, and poor connection during connection, but also helps to ensure the stability and reliability of the electrical connection during use.

[0028] refer to Figure 2 , Figure 3 , Figure 5 and Figure 7 Assembly parts 12 and receiving parts 13 can be provided on the pin guide plate 10, and their specific structure, configuration quantity and layout position can be designed as needed.

[0029] For example Figure 2 As shown, an assembly part 12 can be provided on the left and right sides of the pin header guide plate 10, that is, in Figure 2The first assembly portion 121 and the second assembly portion 122 shown in the figure may have the same or different structural configurations. As an example, the assembly portion 12 may be configured as a structure extending outward from the surface of the pin header guide plate 10, for example, forming a column shape. The cross-section of such a column can be optionally configured as any suitable shape such as a circle, a semi-circle, an ellipse, a polygon, or an irregular shape, so that it can be matched and engaged with the corresponding mating portion 32 (such as a mounting hole) on the electronic component 30 during the assembly operation, thereby assembling the pin header guide plate 10 and, in turn, the electrical connector 100 relative to the electronic component 30.

[0030] exist Figure 1 In the electronic device 200, electronic component 30 is specifically shown as a PCB (Printed Circuit Board) for illustrative purposes. It should be noted that other types of electronic component 30 are permissible. For example, in one or more embodiments, electronic component 30 may be another electrical connector that corresponds to and mates with electrical connector 100. This application does not impose any limitations on electronic component 30.

[0031] like Figure 3 and Figure 5 As shown, protrusions 14 can be provided on the outer periphery of the assembly portion 12 of the pin header guide plate 10. The specific structure, number, and layout of the protrusions 14 can be designed as needed. For example, the protrusions 14 on the first assembly portion 121 and the second assembly portion 122 can be constructed with different structural forms and different numbers. For instance, the number of protrusions 14 on the first assembly portion 121 (e.g., 2) can be less than the number of protrusions on the second assembly portion 122 (e.g., 3). This will facilitate easy identification and positioning during installation and avoid incorrect installation operations. The protrusions 14 can form a pressing force with the mating portion 32 on the electronic component 30 during assembly, thereby promoting a more stable installation of the pin header guide plate 10 and the pin header 20 relative to the electronic component 30.

[0032] The receiving portion 13 can be disposed on the surface of the pin header guide plate 10 and arranged adjacent to the protrusion 14. For example, the receiving portion 13 can be configured as a recessed portion forming downward from the surface, and the protrusion 14 can be configured to extend from the recess along the length direction of the assembly portion 12. The receiving portion 13 can store particles that may be generated during the assembly process, which are typically generated when the protrusion 14 is pressed against and moves relative to the mating portion 32. This effectively solves the problem of these particles being stuck by the pin header guide plate 10 or electronic component 30 during assembly, affecting product installation quality and performance. It ensures that the pin header guide plate 10, pin header 20, and electronic component 30 are in the desired correct position after installation, reducing or eliminating the installation gap between the pin header guide plate 10 and electronic component 30, thereby improving the quality of the electronic device.

[0033] exist Figure 4 and Figure 6 The comparison shows an existing pin header guide plate structure. Since the pin header guide plate 10' does not have a structure that is the same as or similar to the aforementioned receiving part, particles generated during the assembly process are prone to accumulate. This can cause the existing pin header guide plate and electronic components to deviate from the ideal installation position, and may further affect the structural stability during use, which is not conducive to the stable and reliable transmission of electrical connection signals, data, etc. between the pin header and electronic components.

[0034] As mentioned above, this application allows the receiving portion 13 to be flexibly configured according to the actual application. For example, one receiving portion 13 can be provided for each protrusion 14, or the receiving portion 13 can be constructed to have one or more openings 15 with an outward-facing structure so that even if a large amount of particles accumulate in the receiving portion 13, excess particles can be discharged through the openings 15, so that the receiving portion 13 can maintain good holding capacity during continuous assembly. This is very beneficial for eliminating the installation gap between the pin header guide plate 10 and the electronic component 30, so that after the pin header guide plate 10 is installed relative to the electronic component 30, the surface of the pin header guide plate 10 can directly abut against the surface of the electronic component 30, thereby achieving a stable and reliable installation quality.

[0035] The above has been combined Figure 1 Specific examples detail the pin header guide plate, electrical connector, and electronic device according to this application. The solution of this application, compared to, for example... Figure 4 and Figure 6The existing pin header guide shown has significant technical advantages. Such pin header guides, electrical connectors, and electronic devices can be widely used in various possible applications, such as ECUs (Electrical Control Units) and HCUs (Hybrid Control Units) in vehicles and other equipment.

[0036] The pin header guide plate, electrical connector, and electronic device according to this application are illustrated in detail above by way of example only. These examples are for illustrating the principles and implementation methods of this application only, and are not intended to limit this application. Various modifications and improvements can be made by those skilled in the art without departing from the scope of this application. Therefore, all equivalent technical solutions should fall within the scope of this application and be defined by the claims of this application.
