[0002] The safety ground connector is an electrical connector used in electrical equipment or systems, which provides safe and reliable electrical connection while meeting the requirements of relevant safety standards (such as IEC, UL or national standards);

[0003] The safety ground connector is used to reliably connect two circuits together to achieve the transmission of electrical energy or signals. The safety ground connector is designed to meet relevant safety standards (such as protection against electric shock and short circuit), which can prevent accidental contact with electric current and improve safety in use, especially in high-voltage or industrial application scenarios. Through the safety ground connector, devices or components can be quickly and conveniently connected or disconnected, simplifying the installation and maintenance process. The safety ground connector has functions such as high-temperature resistance, flame retardation, dust prevention and waterproofing, which can protect the circuit from environmental influences and prolong the service life of the equipment.

[0004] The existing positive pin of the safety ground connector is composed of a copper needle folded into a Z shape, so the needle and the pin are prone to deformation, which cannot ensure the 90-degree perpendicularity of the pin and the needle, thereby reducing the reliability of the safety ground connector. Therefore, a novel safety ground connector is proposed to solve the above problems. SUMMARY

[0005] To overcome the above shortcomings, the utility model provides a novel safety ground connector, aiming to improve the problem of the existing positive pin of the safety ground connector being composed of a copper needle folded into a Z shape, which is prone to deformation and cannot ensure the 90-degree perpendicularity of the pin and the needle, thereby reducing the reliability of the safety ground connector.

The negative copper pipe assembly comprises a negative copper pipe body, one end of which is fixedly connected with a connecting piece, and the surface of the connecting piece is fixedly connected with a negative pin. The inner wall surface of the safety ground connector shell is fixedly connected with a first insulating sleeve, and the surface of the negative copper pipe body is fixedly connected with a first limiting boss. A first limiting groove is formed in one end of the negative pin close to the first insulating sleeve.

[0007] The positive copper needle assembly includes a copper needle body, a rivet is fixedly connected to one end of the copper needle body close to the safety female socket housing, a positive electrode pin is riveted to one end of the rivet close to the safety female socket housing, a second limiting boss is fixedly connected to the surface of the copper needle body, a second insulating sleeve is fixedly connected to the inner wall surface of the negative copper tube body, and a second limiting groove is formed on the surface of the second insulating sleeve close to the positive electrode pin;

[0008] As a further description of the above technical solution: the surface of the safety female socket housing is symmetrically provided with heat dissipation holes, the center of the bottom surface of the safety female socket housing is provided with a first connection port, and the two sides of the bottom surface of the safety female socket housing are opposite to each other.

[0009] As a further description of the above technical solution: the first connection port is communicated with the interior of the safety female housing, and the second connection port is communicated with the interior of the safety female housing;

[0010] As a further description of the above technical solution: the positive electrode pin is riveted to the copper pin body at 90 degrees by a rivet, and the safety female socket housing is made by injection molding of an insulating heat-resistant plastic material;

[0011] As a further description of the above technical solution: the negative electrode pin passes through the second connecting port, and the positive electrode pin passes through the first connecting port;

[0012] As a further description of the above technical solution: the first limiting boss is clamped in the interior of the first limiting groove, and the second limiting boss is clamped in the interior of the second limiting groove;

[0013] As a further description of the above technical solution: the first insulating sleeve is arranged below the second insulating sleeve, and the first insulating sleeve and the second insulating sleeve form a stepped abutment;

[0014] As a further description of the above technical solution: the first insulating sleeve and the second insulating sleeve are both made of insulating materials, the first insulating sleeve is arranged on the surface of the negative copper tube body, and the second insulating sleeve is arranged on the surface of the copper needle body.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the present invention, by using the positive copper needle assembly and the negative copper tube assembly in combination, the position and orientation of the negative copper tube body, the negative pin, the copper needle body and the positive pin can be located, thereby avoiding damage to the contact point or signal interference, ensuring that the contact surface with the target is completely consistent, reducing contact resistance, and improving signal transmission efficiency and quality. Since the first insulating sleeve and the second insulating sleeve form a stepped abutment, the fixity of the entire safety female socket is increased. Through 90-degree riveting, the 90-degree verticality of the positive pin is well guaranteed, thereby improving the reliability of the product.

[0017] 2. In the present invention, the first insulating sleeve and the second insulating sleeve are both made of insulating material and are flame retardant and high temperature resistant, thereby improving the safety of the entire safety mother seat.

[0025] The positive copper needle assembly 4 includes a copper needle body 41, and the copper needle body 41 is fixedly connected to a rivet 42 at one end close to the safety female socket housing 1. The rivet 42 is riveted to a positive pin 43 at one end close to the safety female socket housing 1. The surface of the copper needle body 41 is relatively fixedly connected to a second limiting boss 44, and the inner wall surface of the negative copper tube body 31 is fixedly connected to a second insulating sleeve 45. The second insulating sleeve 45 is relatively provided with a second limiting groove 46 on the surface of one end close to the positive pin 43. The first limiting boss 35 is clamped in the inside of the first limiting groove 36, and the second limiting boss 44 is clamped in the inside of the second limiting groove 46. The first insulating sleeve 34 is arranged below the second insulating sleeve 45. On the other hand, the first insulating sleeve 34 and the second insulating sleeve 45 form a stepped abutment. The first insulating sleeve 34 and the second insulating sleeve 45 are both made of insulating material. The first insulating sleeve 34 is sleeved on the surface of the negative copper tube body 31, and the second insulating sleeve 45 is sleeved on the surface of the copper needle body 41, so as to locate the position and orientation of the negative copper tube body 31, the negative pin 33, the copper needle body 41 and the positive pin 43, avoid damage to the contact point or signal interference, ensure that the contact surface with the target is completely consistent, can reduce contact resistance, and improve signal transmission efficiency and quality. Since the first insulating sleeve 34 and the second insulating sleeve 45 form a stepped abutment, the fixity of the entire safety female socket is increased.
