Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a plug-in terminal structure. Background Art

[0002] Plug terminals are widely used in electronic products. Their main functions are to connect power and transmit signals. They are mainly used to connect PCBs to PCBs or PCBs to loads.

[0003] The existing terminal structure is composed of an insulating shell and an insulating base, which contain a metal needle and needle slot respectively. The needle and the needle slot are plugged in to form a loop, so that the PCB and the PCB or the PCB and the load are connected. For electronic products that have been idle for a certain period of time, static electricity is generally stored inside the product. If there is static electricity inside the PCB or the load before plugging in, when the plugging forms a loop, the terminal will provide a transmission path for interference signals such as electrostatic discharge while transmitting the signal.

[0004] In a dry environment, the voltage of human body static electricity can reach 6 to 35KV. When touching the PCB plug terminals with your hands, if there is no relevant protection, it is very likely that the components and products will be disturbed, or even the products or components on the PCB will be damaged. Therefore, static electricity protection of the plug terminals is also very important. Summary of the invention

[0056] In some of the above embodiments of the present invention, the shielding assembly 300 also includes a limit member 303 arranged in the male connector 100, and the limit member 303 is arranged on the moving path of the metal spring 302. When the male connector 100 is plugged into the female connector 200, since the limit member 303 is arranged on the moving path of the metal spring 302, the metal spring 302 can be driven away from the male needle body 101, so that the male needle body 101 is separated from the metal spring 302, thereby preventing the effective signal from flowing to the ground after the male connector 100 is plugged into the female connector 200.

[0057] In some embodiments of the present invention, the stopper 303 is a cone structure. The cone structure can wrap the male needle body 101 from all sides, completely isolating the male needle body 101 from the metal spring 302, and ensuring the transmission of effective signals after the male connector 100 and the female connector 200 are plugged in.

At the same time, the static electricity from the outside will flow to the ground through the shielding shell 206, so as to prevent the product from being interfered with by static electricity.

[0071] Embodiment 1:

[0072] The present invention provides a plug-in terminal structure, such as Figure 1-Figure 7 As shown, including:

[0073] A male connector 100, wherein a male needle body 101 is disposed inside the male connector 100;

[0074] A female connector 200, wherein a female plug 201 is disposed inside the female connector 200, and a female needle groove 202 is disposed on the female plug 201, and the female needle groove 202 cooperates with the male needle body 101;

[0075] A shielding assembly 300 for a grounding wire, the shielding assembly 300 comprising a first shielding cover 301 and a stopper 303 disposed in the male connector 100, the first shielding cover 301 being disposed in the female connector 200 and sleeved on the outside of the female plug 201;

[0076] A metal spring 302 is arranged on one side of the first shielding cover 301 close to the male connector 100. The metal spring 302 is arranged on the moving path of the male needle body 101 and is used to connect the male needle body 101 to the ground wire when the male connector 100 is plugged into the female connector 200.

[0077] The limiting member 303 is disposed on the moving path of the metal spring 302 , and is used to drive the metal spring 302 to move away from the male needle body 101 after the male connector 100 and the female connector 200 are plugged into each other.

[0078] The plug terminal structure provided by the present invention includes a male connector 100, a female connector 200 and a shielding assembly 300 for a grounding wire. The shielding assembly 300 includes a first shielding cover 301 and a stopper 303. The first shielding cover 301 is sleeved on the outside of the female plug 201 to shield interference. A metal spring 302 is provided on the first shielding cover 301. The metal spring 302 is provided on the moving path of the male needle body 101 to connect with the male needle body 101 to conduct the grounding wire when the male connector 100 is plugged into the female connector 200, thereby The electrostatic interference stored in the PCB and the load at the male connector 100 end can flow to the ground through the first shielding cover 301, thereby preventing the product from being interfered with by electrostatic electricity, effectively protecting the product, and preventing product abnormalities or damage caused by static electricity; and when the male connector 100 is plugged into the female connector 200, the limiter 303 is set on the moving path of the metal spring 302, which can drive the metal spring 302 away from the male needle body 101, so that the male needle body 101 is separated from the metal spring 302, thereby preventing the effective signal from flowing to the ground after the male connector 100 is plugged into the female connector 200.

[0079] It should be noted that when there is stored electrostatic interference between the PCB and the load, during the plug-in process of the plug-in terminal structure provided by the present invention, the male pin body 101 will first contact the metal spring 302. At the moment of contact, since the metal spring 302 is connected to the first shielding cover 301 of the grounding wire, the electrostatic interference always flows to the position with low impedance. Therefore, the interference eventually flows to the ground through the first shielding cover 301, thereby preventing the product from being affected by electrostatic interference.

[0080] When there is external interference, the first shielding cover 301 can shield the interference, and the electrostatic interference can flow to the ground through the first shielding cover 301, greatly reducing the impact of the electrostatic interference on the plug-in terminal structure.

[0084] Furthermore, the female plug 201 is connected to a wire, and a shielding shell 206 is provided on the female connector 200, and the shielding shell 206 is wrapped around the outside of the wire;

[0085] One end of the shielding shell 206 is connected to the first shielding cover 301 , and the other end of the shielding shell 206 is grounded, so that the first shielding cover 301 is grounded.

[0086] In this further solution, the first shielding shell 301 is grounded through the shielding shell 206, and the shielding shell 206 is sleeved on the outside of the wire, so as to prevent the static electricity from the outside from entering the inside of the female plug 201 through the gap between the wire and the female shell 203, and effectively prevent the static electricity from the outside from interfering with the plug terminal structure provided by the present invention. At the same time, the static electricity from the outside will flow to the ground through the shielding shell 206, so as to prevent the product from being interfered with by static electricity.

[0087] Specifically, in this embodiment, the stopper 303 is a cone-shaped structure, is integrally formed with the male housing 102, and is wrapped around the outer periphery of the male needle body 101 to effectively protect the male needle body 101 and prevent the male needle body 101 from deforming. The stopper 303 is made of insulating material.
