In order to facilitate description, the up-down, left-right and front-back directions in the utility model are relative positions, which do not constitute limitation and definition. In other embodiments, the butt direction of the electric connector and the butt connector can also be the downward direction in the up-down direction, and in other embodiments, the directions of the butt direction, the first direction and the second direction can be interchanged, which is not specifically limited in the utility model.

[0029] Please refer to Figures 1 to 3 The electric connector of the utility model comprises an insulating body 1 and a plurality of power terminals 2 and a plurality of signal terminals 3 accommodated in the insulating body 1, a butt connector comprises a butt body 4 and a plurality of power contact pieces 5 and a plurality of signal contact pieces 6 accommodated in the butt body 4, and the electric connector is connected to the butt connector along the butt direction (namely the upward direction in the up-down direction in the embodiment) to jointly constitute an electric connector combination.

[0030] As Figure 1 And Figures 4 to 6As shown, the insulating body 1 is made of insulating plastic material, the insulating body 1 defines a mating end 17 along the up-down direction for mating with a mating connector and an installation end 18 opposite to the mating end 17 for being installed on a circuit board, the insulating body 1 is spaced apart along a first direction (i.e. left-right direction in the embodiment) perpendicular to the mating direction and is provided with a power receptacle area P1 and a signal receptacle area P2, the signal receptacle area P2 is provided with a plurality of independent signal terminal slots 12 along the up-down direction for one-to-one corresponding receiving a plurality of signal terminals 3, the plurality of signal terminal slots 12 are independently arranged to shield the signal interference between adjacent signal terminals 3, the power receptacle area P1 is provided with a plurality of independent power terminal slots 11 along the up-down direction for one-to-one corresponding receiving a plurality of power terminals 2, the plurality of power terminal slots 11 are independently arranged to prevent the plastic between adjacent power terminal slots 11 from being broken by large current, in the embodiment, the insulating body 1 includes one signal receptacle area P2 and two power receptacle areas P1 respectively located on the left and right sides of the signal receptacle area P2, by dispersing the plurality of power terminals 2 on the left and right sides of the insulating body 1, the temperature rise thermal field effect of the power terminals 2 is reduced, and the heat dissipation effect of the power terminals 2 is improved; the size of each power terminal slot 11 is greater than the size of each signal terminal slot 12, i.e. the size of each power terminal 2 is greater than the size of each signal terminal 3, so as to facilitate the power terminals 2 to carry large current, and the heat dissipation area of the power terminals 2 is increased, and the heat dissipation effect of the power terminals 2 is improved. The plurality of power terminal slots 11 of each power receptacle area P1 are arranged into two rows along a second direction (i.e. front-back direction in the embodiment) perpendicular to the mating direction and the first direction, and the plurality of signal terminal slots 12 are arranged into multiple rows along the front-back direction, in other embodiments, the plurality of power terminal slots 11 can also be arranged into multiple rows greater than two rows along the front-back direction, and the plurality of signal terminal slots 12 can also be arranged into two rows along the front-back direction. Figure 6As shown, in the front-rear direction, the plastic wall thickness D1 between every two adjacent power terminal grooves 11 in a row is greater than the plastic wall thickness D2 between every two adjacent signal terminal grooves 12 in a row, which can not only ensure that the wall thickness between the two adjacent power terminal grooves 11 is large enough to isolate the two adjacent power terminals 2 and prevent the plastic between the two adjacent power terminal grooves 11 from being broken due to the transmission of large current by the power terminals 2, but also can accommodate a sufficient number of signal terminals 3 to facilitate signal transmission. In the left-right direction, the wall thickness between the signal receiving area P2 and each power receiving area P1 is greater than the wall thickness between every two adjacent power terminal grooves 11 in a row, which can avoid the wall thickness between the signal receiving area P2 and the power receiving area P1 being too different from the wall thickness between the two adjacent power terminal grooves 11 in the left-right direction, so that the molten plastic is more likely to flow to the periphery of the insulating body 1 first during injection molding, and ensure that the molten plastic can flow uniformly to fill the area between the signal receiving area P2 and the power receiving area P1. In other embodiments, the wall thickness between the signal receiving area P2 and each power receiving area P1 can also be equal to the wall thickness between every two adjacent power terminal grooves 11 in a row in the left-right direction. Each power receiving area P1 is integrally connected to a mounting end 18 away from the mating end 17 through a reinforcing flange 13, which can strengthen the strength of the mounting end 18 to prevent the mounting end 18 from being deformed when it is mounted to the circuit board, and ensure that each power terminal 2 and each signal terminal 3 can be stably welded. Each reinforcing flange 13 is formed in the left-right direction and the front-rear direction and only surrounds the outer periphery of the corresponding power receiving area P1 to strengthen the strength of the power receiving area P1, prevent the plastic of the power receiving area P1 from being abraded and deformed due to collision when the insulating body 1 is plugged into the mating connector, and avoid the power terminals 2 from being exposed. Each reinforcing flange 13 is provided with a narrowing edge 131 on the side close to the signal receiving area P2, which extends obliquely towards the signal receiving area P2 so that its width in the front-rear direction gradually decreases towards the signal receiving area P2, which can make the end of the reinforcing flange 13 transition smoothly, avoid the molten plastic from foaming at the right-angle transition due to the sudden change in flow direction when flowing in the left-right direction, and avoid the problem of uneven wall thickness caused by the reinforcing flange 13 surrounding the signal receiving area P2.In the front-rear direction, the distance D3 between the outer edge of each reinforcing flange 13 and its adjacent outermost power terminal slot 11 is greater than the distance D4 between the outer wall surface of the signal housing area P2 and its adjacent outermost signal terminal slot 12, so as to avoid the distance between the outer wall surface of the signal housing area P2 and its adjacent outermost signal terminal slot 12 in the front-rear direction being too large, causing the molten plastic to flow more towards the periphery of the signal housing area P2 during injection molding, resulting in uneven wall thickness between adjacent signal terminal slots 12, ensuring that the molten plastic can flow uniformly during the injection molding of the signal housing area P2 to fully fill the plurality of signal terminal slots 12, ensuring that the signal terminal slots 12 are fully formed and have uniform wall thickness, improving the flatness and structural strength of the insulation body 1, and reducing product failure rate. Further, the two outer wall surfaces of the front and rear of the signal housing area P2 for connecting the mating end 17 and the mounting end 18 are both vertical planes, to ensure that the distance between the outer wall surface of the front and rear of the signal housing area P2 and its adjacent outermost signal terminal slot 12 is close to the wall thickness between the two adjacent signal terminal slots 12 in the row at all places, to ensure that each signal terminal slot 12 can be fully filled and formed. Further, in the left-right direction, the extension length of one reinforcing flange 13 is greater than the length of the other reinforcing flange 13, to prevent mistakes. The side of each reinforcing flange 13 away from the mating end 17 is formed with a positioning column 132 to be fixed to the circuit board, and the diameter of the positioning column 132 of the reinforcing flange 13 with longer length is greater than the diameter of the other positioning column 132, to prevent mistakes when the electrical connector is mounted to the circuit board. Figure 1 and Figure 4The first and second protrusions 14 and 15 are arranged on the side of each power accommodation area P1 facing away from the signal accommodation area P2 in the left-right direction. The width of each first protrusion 14 is greater than the width of the corresponding second protrusion 15 in the front-rear direction. The side of each first and second protrusion 14 away from the docking connector is connected to the corresponding reinforcing flange 13 to enhance the strength of the first and second protrusions 14 and 15. The front and rear sides of each power accommodation area P1 are respectively concavely formed with a limiting groove 16. In other embodiments, one side of each power accommodation area P1 in the front-rear direction can also be concavely formed with a limiting groove 16. In the present embodiment, the width of each limiting groove 16 in the left-right direction is less than the distance between the two adjacent power terminal grooves 11 in the left-right direction, so as to prevent the wall thickness between the outer side wall of the power accommodation area P1 and the outermost power terminal groove 11 in the front-rear direction from being too thin, thereby ensuring the strength of the power accommodation area P1. In other embodiments, the width of each limiting groove 16 in the left-right direction can also be equal to the distance between the two adjacent power terminal grooves 11 in the left-right direction. In the front-rear direction, one end of each limiting groove 16 facing the docking connector penetrates the end face of the corresponding power accommodation area P1, and the other end of each limiting groove 16 away from the docking connector is blocked by the corresponding reinforcing flange 13, so as to enhance the strength of the area of the power accommodation area P1 concavely formed with the limiting groove 16.

[0031] As shown in Figure 1 , the plurality of signal terminals 3 are respectively and one-to-one accommodated in the plurality of signal terminal grooves 12. Each signal terminal 3 includes a signal fixed segment 31 fixed to the corresponding signal terminal groove 12 and a signal welding segment 33 connected to the side of the signal fixed segment 31 away from the docking connector. Each signal welding segment 33 extends out of the corresponding signal terminal groove 12 to be welded and fixed to the circuit board. The side of each signal fixed segment 31 facing the docking connector extends a plurality of signal contact segments 32 to collectively contact the corresponding signal contact piece 6.

[0032] Please refer to Figure 1 , Figure 3 and Figure 6The plurality of power terminals 2 are respectively and one-to-one accommodated in the plurality of power terminal grooves 11. Each power terminal 2 has a U-shaped bending section 21 fixed to the corresponding power terminal groove 11 and an opening 211 formed on one side of the U-shaped bending section 21. A power soldering section 23 extends from the side of the U-shaped bending section 21 opposite the opening 211. Each power soldering section 23 extends out of the corresponding power terminal groove 11 to be soldered and fixed to the circuit board. A plurality of power contact sections 22 extend from each U-shaped bending section 21 in the up-down direction to collectively contact the corresponding power contact piece 5. In other embodiments, only one power contact section 22 can extend from each U-shaped bending section 21. In the front-rear direction, the openings 211 of every two adjacent power terminals 2 in a row are oppositely arranged. In the front-rear direction, the distance between every two adjacent power soldering sections 23 in a row is greater than the distance between every two adjacent signal soldering sections 33 in a row, so as to increase the creepage distance between the two adjacent power soldering sections 23 in the front-rear direction.

[0033] As Figure 1 and Figure 7 、 Figure 8As shown, the docking body 4 is made of insulating plastic material, and the docking body 4 is recessed in a receiving cavity 41 towards the direction away from the electrical connector to accommodate the plurality of signal contacts 6 and the plurality of power contacts 5. In the present embodiment, the plurality of signal contacts 6 are located in the middle of the receiving cavity 41 in the left-right direction, and the plurality of power contacts 5 are respectively arranged on the left and right sides of the receiving cavity 41, and in the front-rear direction and in the left-right direction, the distance between each adjacent two power contacts 5 is greater than the distance between each adjacent two signal contacts 6, so as to reduce the temperature rise effect of the power contacts 5 and improve the heat dissipation effect of the power contacts 5. The inner walls of the left and right sides of the receiving cavity 41 are respectively recessed with a first groove 43 and a second groove 44, and in the front-rear direction, the width of each first groove 43 is greater than the width of the corresponding second groove 44, and each first groove 43 and the corresponding second groove 44 has a partition 45, and the width of each partition 45 in the front-rear direction is greater than the distance between each adjacent two power contacts 5 in a row, so as to facilitate the molding of the first groove 43 and the second groove 44, prevent the width of the partition 45 in the front-rear direction from being too small and easily broken, avoid affecting the concave-convex cooperation between each first protrusion 14 and the corresponding first groove 43, and the cooperation between each second protrusion 15 and the corresponding second groove 44, and ensure the cooperation positioning effect of the electrical connector and the docking connector.

[0036] (1) In the left-right direction, the wall thickness between the signal receiving area P2 and each power supply receiving area P1 is greater than or equal to the wall thickness between each adjacent two power terminal grooves 11 in a row, avoiding the wall thickness between the signal receiving area P2 and the power supply receiving area P1 being too different from the wall thickness between the adjacent two power terminal grooves 11, causing the molten plastic to flow more towards the periphery of the signal receiving area P2 during injection molding, ensuring that the molten plastic can flow uniformly to fill the area between the signal receiving area P2 and the power supply receiving area P1 during injection molding; the power supply receiving area P1 is integrally connected with a reinforcing flange 13 on the side away from the docking end 17, and the reinforcing flange 13 only surrounds the power supply receiving area P1, to strengthen the strength of the power supply receiving area P1, prevent the plastic of the power supply receiving area P1 from being abraded and deformed due to collision when the insulation body 1 is inserted into the docking connector, and avoid the power terminal 2 from being exposed; in the front-back direction, the distance D3 between the outer edge of each reinforcing flange 13 and the outermost adjacent power terminal groove 11 is greater than the distance D4 between the outer wall surface of the signal receiving area P2 and the outermost adjacent signal terminal groove 12, avoiding the distance between the outer wall surface of the signal receiving area P2 and the outermost adjacent signal terminal groove 12 being too different in the front-back direction, causing the molten plastic to flow more towards the periphery of the signal receiving area P2 during injection molding, resulting in uneven wall thickness between the adjacent signal terminal grooves 12, ensuring that the molten plastic can flow uniformly to fully fill the multiple signal terminal grooves 12 during the injection molding of the signal receiving area P2, ensuring that the signal terminal grooves 12 are molded completely and uniformly in thickness, improving the appearance flatness and structural strength of the insulation body 1, and reducing the product failure rate; the side of each reinforcing flange 13 close to the signal receiving area P2 is provided with a narrowed edge 131, so that the end of the reinforcing flange 13 transitions smoothly, avoiding the molten plastic from foaming at the right angle transition due to the sudden change in flow direction when flowing in the first direction, and avoiding the problem of uneven wall thickness caused by the reinforcing flange 13 surrounding the signal receiving area P2.

[0037] (2) The insulation body 1 includes one signal receiving area P2 and two power supply receiving areas P1 located on the left and right sides of the signal receiving area P2, by dispersing multiple power terminals 2 on the left and right sides of the insulation body 1, reducing the temperature rise thermal field effect of the power terminal 2, and improving the heat dissipation effect of the power terminal 2; the multiple signal contacts 6 of the docking connector are located in the middle of the receiving cavity 41, and the multiple power contacts 5 are located on the left and right sides of the receiving cavity 41, and in the front-back direction and in the left-right direction, the distance between each adjacent two power contacts 5 is greater than the distance between each adjacent two signal contacts 6, reducing the temperature rise thermal field effect of the power contacts 5, and improving the heat dissipation effect of the power contacts 5.

[0038] (3) In the front-rear direction, the width of each first protrusion 14 is greater than the width of the corresponding second protrusion 15, and the width of each first groove 43 is greater than the width of the corresponding second groove 44, so that each first protrusion 14 and the corresponding first groove 43 are in a concave-convex fit, and each second protrusion 15 and the corresponding second groove 44 are in a concave-convex fit, to facilitate foolproofing; each first protrusion 14 and each second protrusion 15 are connected to the corresponding reinforcing flange 13 away from the side of the mating connector, to enhance the strength of the first protrusion 14 and the second protrusion 15; each first groove 43 and the corresponding second groove 44 have a partition 45 therebetween, and the width of each partition 45 in the front-rear direction is greater than the distance between each adjacent two power contact pieces 5 in a row, to facilitate the molding of the first groove 43 and the second groove 44, prevent the width of the partition 45 in the front-rear direction from being too small and easily broken, avoid affecting the concave-convex fit of each first protrusion 14 and the corresponding first groove 43, and the concave-convex fit of each second protrusion 15 and the corresponding second groove 44, and ensure the mating positioning effect of the electrical connector and the mating connector.

[0039] (4) Each limiting groove 16 and the corresponding protruding rib 42 are in a concave-convex fit to limit the insertion of the insulating body 1 in the left-right direction, and the end of each limiting groove 16 away from the mating connector is blocked by the corresponding reinforcing flange 13 to enhance the strength of the area of the power supply accommodation area P1 in which the limiting groove 16 is recessed; the width of each limiting groove 16 in the left-right direction is less than or equal to the distance between the adjacent two power terminal grooves 11 in the left-right direction, to avoid the power contact piece 5 adjacent to the protruding rib 42, and prevent the wall thickness between the outermost power terminal groove 11 in the front-rear direction and the outer side wall surface of the power supply accommodation area P1 from being too thin, to ensure the strength of the power supply accommodation area P1.

[0040] (5) Each power terminal 2 has a power welding section 23 extending from the side of the U-shaped bending section 21 opposite the opening 211, and in the front-rear direction, the openings 211 of each adjacent two power terminals 2 in a row are arranged opposite each other. In the front-rear direction, the distance between each adjacent two power welding sections 23 in a row is greater than the distance between each adjacent two signal welding sections 33 in a row, to increase the creepage distance between the front-rear adjacent two power welding sections 23.

[0041] (6) The front and back inner wall surfaces of the area where the receiving cavity 41 receives the power contact 5 are respectively provided with a protruding rib 42 to enhance the strength of the front and back side walls of the area where the docking body 4 is provided with the power contact 5. The projection of the protruding rib 42 of the front and back sides of the receiving cavity 41 along the up-down direction overlaps the projection of the corresponding reinforcing flange 13 along the up-down direction, preventing the reinforcing flange 13 from colliding with the front and back side walls of the area where the docking body 4 is provided with the power contact 5 when the power receiving area P1 is inserted into the receiving cavity 41, and preventing the front and back side walls of the area where the docking body 4 is provided with the power contact 5 from being worn out by the impact.

[0042] (7) The front and back outer wall surfaces of the signal receiving area P2, which are used to connect the docking end 17 and the mounting end 18, are vertical planes, to ensure that the distance between the outer wall surfaces of the front and back sides of the signal receiving area P2 and the outermost signal terminal slot 12 adjacent thereto is close to the wall thickness between the two adjacent signal terminal slots 12 in the row at all places, to ensure that each signal terminal slot 12 can be fully filled and formed.

Therefore, any equivalent technical changes made according to the content of the present application and drawings are included in the patent scope of the present application.
