[0002] With the rapid development of the automotive industry, the complexity of automotive electronic systems is increasing. As a key electrical connection component, POGO pins are becoming increasingly common in vehicles. With their unique elastic structure and excellent contact performance, POGO pins enable fast and reliable connections between electronic components, especially in environments where frequent plugging and unplugging is required. However, existing POGO pin technology presents a significant technical challenge during vehicle operation, particularly over bumpy roads.

[0003] In real-world scenarios, when a car travels on bumpy roads, the car body experiences irregular vibrations and impacts. These vibrations and impacts are transmitted to the POGO pins, causing relative displacement between the contact point and the corresponding contact surface. This displacement can easily lead to poor contact, which in turn causes signal transmission interruption. Signal interruption not only affects the normal operation of the car's electronic systems but also poses a potential threat to driving safety. Furthermore, poor contact can degrade signal quality, impacting the performance of the electronic systems.

[0028] The electrical connector described in this embodiment achieves a fixed relative position between the needle tube 110 and the needle shaft 120 through the limiting mechanism 200 and the elastic member 130. Furthermore, the special structural arrangement of the limiting connector 220 enables a stable connection and fit of the aforementioned structure. In actual use, the present application can fundamentally prevent contact position deviation, thereby maintaining a stable electrical connection. Compared to existing conventional electrical connection components, the present application has significant advantages such as a high degree of structural fit, a long service life, good operational stability, and a wide range of applications, and has broad prospects for use in the industry.

[0029] See also Figure 1 As shown, the housing 100 in this embodiment plays the main role of electrical connection, wherein the needle tube 110 is used to provide a mounting and connection platform for its internal structure, and the needle shaft 120 is used to cooperate with the needle tube 110 to achieve electrical connection. Furthermore, the needle tube 110 includes a bottom plate 111 and a barrel 112, wherein the bottom plate 111 and the needle shaft 120 are respectively arranged at opposite ends of the barrel 112, and the guide shaft 210 abuts against the bottom plate 111. The interior of the barrel 112 is a component installation space, and the bottom plate 111 is connected to one end of the barrel 112 to fix the limiting mechanism 200 in its axial direction. The other end of the barrel 112 is provided with a connection structure that cooperates with the needle shaft 120.

[0030] Further, see Figure 2As shown, the needle shaft 120 includes an inner shaft 121 and an outer shaft 122. The outer shaft 122 is hollow inside. The inner shaft 121 is connected to the end of the outer shaft 122 away from the needle tube 110, and the limiting connector 220 is connected to the inside of the outer shaft 122. Correspondingly, the needle shaft 120 is also provided with a connection structure that cooperates with the barrel 112. Based on this, the needle tube 110 is connected to the guide shaft 210, and the needle shaft 120 is connected to the limiting connector 220, thereby realizing a stable assembly connection structure of the electrical connector. Furthermore, the outer shaft 122 is used to achieve a fixed connection between it and the barrel 112, and the inner shaft 121 is set at the center of the cross-section of the outer shaft 122, which is used to achieve electrical connection.

[0031] In addition, the housing 100 in this embodiment further includes an assembly end 140, which is connected to the outer surface of the barrel 112 for connection to an external mounting platform. Specifically, the assembly end 140 is connected to the center of the base plate 111 of the needle tube 110. It can be configured as a threaded fit, a plug-in structure, or other element capable of achieving a connection and installation function, and this utility model does not impose specific limitations on this.

[0032] See also Figure 3 As shown, the guide shaft 210 in this embodiment serves as a core component for maintaining a stable electrical connection. It includes an abutment portion 211, a shaft body 212, and a plug-in portion 213. The abutment portion 211 and the plug-in portion 213 are respectively connected to the two ends of the shaft body 212 in the length direction, wherein the abutment portion 211 abuts against the inner wall of the needle tube 110, and the plug-in portion 213 is inserted and connected to the interior of the limiting connector 220. Furthermore, the shaft body 212 in this embodiment is arranged at the center of the needle tube 110, and coincides with the central axis of the needle tube 110, thereby achieving a limited fixation of the needle shaft 120 on the cross section of the needle tube 110. Furthermore, in the axial direction of the guide shaft 210, the projected area of ​​the abutment portion 211 is larger than the projected area of ​​the shaft body 212. The projected area of ​​the insertion portion 213 gradually decreases in the direction away from the shaft body 212. Based on this structural arrangement, the abutment portion 211 can increase the contact area between it and the base plate 111, thereby further improving the relative stability between the guide shaft 210 and the needle tube 110. The insertion portion 213 is configured to gradually shrink in its axial direction, thereby facilitating its insertion and assembly with the limiting connector 220.

[0033] See also Figure 4As shown, the position-limiting connector 220 includes a connecting ring 221 and at least two claw springs 222. The connecting ring 221 is connected to the inner wall of the needle shaft 120. At least two claw springs 222 have one end connected to the connecting ring 221 and the other end extending toward the interior of the needle shaft 120. Adjacent claw springs 222 are positioned closer together along their extension direction. The connecting ring 221 is configured to connect to the outer shaft 122, and the claw springs 222 are configured to achieve a fixed connection to the guide shaft 210 through lateral compression. Specifically, in this embodiment, multiple claw springs 222 are symmetrically arranged about the central axis of the guide shaft 210. This ensures that the multiple claw springs 222 evenly distribute the compressive force exerted on the guide shaft 210, thereby ensuring the proper installation position and service life of the guide shaft 210. In actual use, the specific number and spacing of the decorative elements can be adjusted based on actual needs, and this is not specifically limited by the present invention.
