[0002] With the rapid development of electric vehicle technology, the performance and safety requirements of systems such as motor controllers (MCU) and power distribution units (PDU), as core components of electric vehicle power systems, are also increasing. In these systems, the application of connectors is crucial. They are responsible for connecting different electrical components, modules and subsystems together to ensure smooth current transmission and stable operation of the system.

[0003] However, existing connectors generally lack effective sealing designs when installed on the chassis. This lack of design results in a gap between the connector and the chassis, which is easily affected by the external environment, such as the intrusion of pollutants such as dust and moisture. This not only affects the electrical performance of the connector, but may also cause safety hazards such as short circuits and corrosion, reducing the reliability and stability of the entire system. Secondly, existing connectors often lack effective anti-touch protection designs after the copper busbar is installed, which means that during maintenance, inspection or misoperation, personnel may directly contact the exposed copper busbar, causing electric shock accidents, which not only threatens the safety of personnel, but may also have a serious impact on the operation of the entire system. Utility Model Content

[0010] Furthermore, a metal bushing is molded in the mounting hole.

[0011] Furthermore, an annular groove surrounding the cylindrical portion is provided on one side of the mounting portion, and an insulating sealing ring is embedded in the annular groove.

[0012] Furthermore, a first accommodating groove and a second accommodating groove which are interconnected are provided in the base, the diameter of the first accommodating groove is larger than the diameter of the second accommodating groove so that the first accommodating groove and the second accommodating groove are combined to form a T-slot structure, and the diameter of the conductive terminal is smaller than the diameter of the second accommodating groove so that there is a gap between the conductive terminal and the base for accommodating glue.

DETAILED DESCRIPTION

[0025] The following detailed description and drawings of the embodiments of the present invention are used to illustrate the principle of the present invention, but cannot be used to limit the scope of the present invention, that is, the present invention is not limited to the embodiments described.

[0026] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0027] See also Figure 1 to Figure 3 As shown, a connector with a threaded structure provided by an embodiment of the utility model comprises a connector body 1 and a cover body 2, wherein the connector body 1 comprises a conductive terminal 11 and a base 12, wherein at least a portion of the conductive terminal 11 is located in the base 12, and a convex portion 121 extending radially outward from the base 12 is provided at one end of the base 12;

[0028] A slot 21 is correspondingly disposed on the inner wall of the cover body 2 , and at least a portion of the protrusion 121 protrudes into the slot 21 .

[0029] In this embodiment, the conductive terminal 11 and the base 12 are coaxially arranged.

[0030] Specifically, when the cover body 2 is tightly matched with the protrusion 121 on the base 12 through the card slot 21, the cover body 2 can completely cover the connection between the connector and the copper bus terminal. This design ensures that the copper bus terminal will not be exposed during the operation of the connector, thereby avoiding electric shock accidents caused by the exposure of the copper bus. Secondly, by matching the protrusion 121 on the base 12 with the card slot 21 on the inner wall of the cover body 2, a relatively stable mechanical connection structure is formed, so that the connector body 1 and the cover body 2 are tightly connected, and can withstand a certain degree of external vibration or impact, reducing the risk of the cover body 2 falling off due to vibration.

[0031] See also Figure 1 and Figure 5As shown, the base 12 includes two anti-rotation planes 122 arranged opposite to each other, the convex portion 121 includes a first straight section 1211, an arc section 1212 and a second straight section 1213, the first straight section 1211 and the second straight section 1213 are respectively located on the two anti-rotation planes 122, and the two ends of the arc section 1212 are respectively connected to the first straight section 1211 and the second straight section 1213, the slot 21 includes a first straight slot 211, a second straight slot 213 and an arc slot 212 respectively connected to the first straight slot 211 and the second straight slot 213, the first straight section 1211 is embedded in the first straight slot 211, the arc section 1212 is embedded in the arc slot 212, and the second straight section 1213 is embedded in the second straight slot 213.

[0032] Specifically, since the protrusion 121 is composed of a first straight section 1211, an arc section 1212, and a second straight section 1213, and the first straight section 1211, the arc section 1212, and the second straight section 1213 are respectively embedded in the first straight groove 211, the arc groove 212, and the second straight groove 213 of the cover body 2, such a design ensures the close contact and close fit between the protrusion 121 and the base 12, significantly improves the connection stability between the connector body 1 and the cover body 2, and reduces looseness or separation caused by vibration, impact or other external forces. Secondly, such a design also takes into account the convenience of installation and disassembly. Since the various sections of the protrusion 121 match the various grooves of the card slot 21, when installing, it is only necessary to insert the protrusion 121 into the card slot 21 in the correct direction, and separation can also be achieved through simple operations when disassembling.

[0033] See also Figure 5 As shown, in order to further enhance the connection firmness between the connector body 1 and the cover body 2 and prevent the risk of the cover body 2 falling off from one end of the connector body 1 when the connector is vibrated by external force, in this embodiment, the first straight section 1211 and the second straight section 1213 of the protrusion 121 are both provided with a limiting groove 1214, and correspondingly, the first straight groove 211 and the second straight groove 213 of the groove are provided with a limiting protrusion 214, when the protrusion 121 of the base 12 is snapped into the groove of the cover body 2, through the protrusion 121 1 and the groove are snap-fitted together, thereby limiting the movement of the cover body 2 in the axial direction A of the base. At the same time, the limiting protrusion 214 is embedded in the limiting groove 1214. The limiting protrusion 214 and the limiting groove 1214 cooperate with each other, and the arc segment 1212 and the arc groove 212 cooperate with each other, so as to limit the movement of the cover body 2 in the radial direction of the base 12, thereby enhancing the connection firmness between the cover body 2 and the base 12, ensuring that the cover body 2 is not easy to move in the X-axis, Y-axis and Z-axis directions, and can effectively prevent the cover body 2 from falling off the base 12.

[0034] See also Figure 1As shown, the base 12 includes a cylindrical portion 12a and a mounting portion 12b formed by the cylindrical portion 12a extending radially outward, the cylindrical portion 12a surrounds at least a portion of the conductive terminal 11, and mounting holes 123 that penetrate the thickness of the mounting portion 12b are provided on both sides of the mounting portion 12b. The base 12 is mounted to the panel of the chassis through the mounting holes 123.

[0035] Without taking additional measures, when screwing directly into the mounting hole 123 for installation, the force-bearing surface of the screw will directly act on the inner wall of the mounting hole 123. Due to various factors such as material strength and screw tightening force, the mounting portion 12b is prone to cracking, thereby affecting the overall structure of the base 12. Based on this, see Figure 4 As shown, the mounting hole 123 in this embodiment is overmolded with a metal bushing 3. By overmolding the metal bushing 3 in the mounting hole 123, the force-bearing surface of the screw no longer directly acts on the inner wall of the mounting hole 123 of the mounting portion 12b, but acts on the stronger and higher-strength metal bushing 3, which greatly reduces the risk of the mounting portion 12b cracking due to force. Secondly, the metal bushing 3 itself has high wear resistance and corrosion resistance, and can maintain good performance even in long-term use or harsh environments, which helps to extend the service life of the base 12 and reduce the maintenance and replacement costs caused by damage to the mounting hole 123. It is worth mentioning that due to the presence of the metal bushing 3, the screws are easy to screw in during the installation process, reducing the risk of damaging the mounting hole 123 due to improper operation during the installation process.

[0036] See also Figure 1-2 As shown, one side of the mounting portion 12b is provided with an annular groove 124 surrounding the cylindrical portion 12a, and an insulating sealing ring 4 is embedded in the annular groove 124. In this embodiment, the insulating sealing ring 4 is a silicone rubber sealing ring. With this design, when the base 12 is installed on the panel of the chassis through the mounting hole 123, the insulating sealing ring 4 is tightly matched with the chassis panel to achieve a sealing effect.

[0037] In this embodiment, since a portion of the connector extends into the interior of the chassis, in order to further enhance the sealing performance inside the chassis, a first accommodating groove 125 and a second accommodating groove 126 that are interconnected are provided in the base 12. The diameter of the first accommodating groove 125 is larger than the diameter of the second accommodating groove 126 so that the first accommodating groove 125 and the second accommodating groove 126 are combined to form a T-slot structure, and the diameter of the conductive terminal 11 is smaller than the diameter of the second accommodating groove 126 so that there is a gap between the conductive terminal 11 and the base 12 for accommodating AB glue. Specifically, AB glue is poured from the first receiving groove 125 with a larger diameter and flows into the second receiving groove 126 with a smaller diameter to seal the gap between the inner wall of the first receiving groove 125 and the conductive terminal 11. Similarly, part of the AB glue is filled in the gap between the inner wall of the first receiving groove 125 and the conductive terminal 11. This design can not only enhance the connection firmness between the conductive terminal 11 and the base 12, but also improve the sealing between the conductive terminal 11 and the base 12, thereby enhancing the sealing performance inside the chassis.

[0038] In this embodiment, the base 12 and the cover 2 are both made of plastic.

[0039] See also Figure 3 As shown, the conductive terminal 11 includes a first wiring screw hole 111 and a second wiring screw hole 112, and the first wiring screw hole 111 and the second wiring screw hole 112 both extend along the axial direction of the conductive terminal 11, wherein the diameter of the first wiring screw hole 111 is smaller than the diameter of the second wiring screw hole 112, specifically, the diameter of the first wiring screw hole 111 is 6 mm, and the diameter of the second wiring screw hole 112 is 8 mm.
