[0045] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0046] The present invention is an electrical connector capable of transmitting large current. Figure 1-3In the first embodiment shown, the rear end of the electrical connector 100 is connected to a cable (not shown) for connecting with the docking connector 300 mounted on the circuit board, and the electrical connector 100 can also transmit signals. Due to the transmission of large currents, the temperature rise requirement is high, and the present invention aims to achieve the purpose by improving the heat dissipation air circulation channel of the electrical connector.

[0047] The electrical connector 100 includes an insulating body 10 and a terminal 20. The insulating body includes a base 17 and a rectangular mating portion 16 extending forward from the base. Figure 4-5 The docking portion 16 includes an upper side wall 11 and a lower side wall 12, and a plurality of vertical walls 13. The two ends of each vertical wall are integrally connected to the upper and lower side walls 11 and 12, respectively. A terminal slot 14 is formed between two adjacent vertical walls 13. In this embodiment, each terminal slot 14 is vertical and passes through the front end surface 160 of the docking portion 16 forward and the rear end surface of the base 17 backward. All terminal slots 14 are arranged horizontally in the left and right directions. Fig.16 The terminal 20 includes a contact portion 21 extending into the terminal slot 14 and a connection portion 22 extending out of the insulating body. Each vertical wall 13 is provided with an upper through hole 131 adjacent to the upper side wall 11. The upper through hole 131 penetrates the vertical wall 13 horizontally and communicates with the adjacent terminal slot 14. The upper side wall 11 is provided with an upper hole 111. The upper hole 111 penetrates the upper side wall 11 vertically and communicates with the upper through hole 131. At the same time, the vertical wall 13 is also provided with a lower through hole 132 adjacent to the lower side wall 12. The lower through hole penetrates the vertical wall 13 horizontally and communicates with the adjacent terminal slot 14. The lower side wall 12 is provided with a lower hole 121. The lower hole 121 penetrates the lower side wall 12 vertically and communicates with the lower through hole 132. In this way, the upper and lower through holes 131, 132, the upper and lower holes 111, 121 and the corresponding terminal slot 14 form a heat dissipation air channel B1 that is connected vertically.

[0048] The docking connector 300 includes a rectangular insulating frame 30 and a sheet terminal 40. The insulating frame is formed of four side walls to form a receiving cavity 31. Each sheet terminal 40 is vertical and protrudes into the receiving cavity 31. All sheet terminals are arranged horizontally in the receiving cavity 31. The upper and lower side walls 32 of the insulating frame are respectively provided with a plurality of through holes 321. Each through hole penetrates from top to bottom and is aligned with the sheet terminal in the up and down direction ( Fig.17 After the two connectors are docked, the electrical connector 100 is inserted into the receiving cavity 31, and the upper and lower holes 111 and 121 of the electrical connector are aligned with the upper and lower through holes 321 of the docking connector, respectively, so as to form a heat dissipation air channel B1. Figure 6 shown.

[0049] In this embodiment, the heat dissipation air channel B2 first passes through the perforation of the vertical wall and then passes through the hole above the perforation. The perforations 131, 132 and the holes 111, 121 are offset from the terminal slot 14. Under the premise of ensuring air circulation, the chance of the terminal 20 in the terminal slot 14 being contaminated can be reduced, especially when the electrical connector 100 is in an exposed state, that is, when the docking connector 300 is not inserted. After the two connectors are docked, the through hole 321 and the holes 111, 121 are also offset in the lateral direction, so that under the premise of ensuring air circulation, the terminals of the two connectors can also reduce the chance of contamination.

[0050] In a specific embodiment, the docking portion 16 is provided with shallow depressions 161 on its upper and lower surfaces, and the upper and lower holes 111 and 121 are both located in the corresponding shallow depressions 161. The shallow depressions 161 are a distance away from the front end surface 160 of the docking portion 16 and a distance away from the junction of the docking portion 16 and the base 17. Figure 5 The upper hole 111 is located directly above the corresponding upper through hole 131, and the lower hole 121 is located directly below the corresponding lower through hole 132. The vertical wall 13 includes at least a first vertical wall 13a and a second vertical wall 13b adjacent to each other. The first vertical wall 13a has the same lateral width, and the lateral widths of the upper and lower holes 111 and 121 are greater than the width of the vertical wall 13a. The lateral width of the second vertical wall 13b is widened near the upper and lower side walls. Figure 6 The inner wall surfaces of the upper and lower side walls of the docking connector 300 are also provided with a groove 322 extending forward. After the two connectors are docked, the groove 322 and the shallow depression 161 further increase the air circulation channel to accelerate the heat dissipation effect.

[0051] In this embodiment, the docking portion 16 is further provided with a plurality of terminal holes 162 that penetrate the front end surface 160 of the docking portion 16 forward on one side of the terminal slot 14. The terminal holes are arranged in a matrix, and the terminal holes are correspondingly accommodated with elastic terminals (not shown). The two lateral ends of the docking portion 16 are respectively provided with guide posts 163, and the guide posts 163 pass forward through the front end surface 160 of the docking portion. The upper and lower side walls of the base 17 are provided with through holes 171 that correspond to the terminal slots 14 one by one, and the through holes penetrate the upper and lower side walls of the base respectively, forming a heat dissipation air circulation channel of this part.

[0052] Figure 7-8The second embodiment of the present invention is shown, and the structure of the docking connector is the same as that of the first embodiment, mainly in that the air circulation channel of the electrical connector is slightly different. The two ends of each vertical wall 13 of the electrical connector 100B are integrally connected to the upper side wall 11 and the lower side wall 12 respectively. The upper side wall 11 is provided with an upper hole 113, which penetrates the upper side wall 11 up and down and connects to the terminal slot 14. The lower side wall 12 is provided with a lower hole 123, which penetrates the lower side wall 12 up and down and connects to the terminal slot 14. The upper and lower holes and the corresponding terminal slots form a heat dissipation air channel connected up and down. After the two connectors are docked, the upper and lower holes are connected with the through hole 321 to form a heat dissipation air channel B2. As can be seen from the figure, these holes are aligned and connected with each other up and down. The lateral width of the upper and lower holes 113, 123 is smaller than the width of the terminal slot 14.

[0053] Figure 9-11 The third embodiment of the present invention is shown, and the structure of the docking connector is the same as that of the first embodiment, mainly in that the air circulation channel of the electrical connector is slightly different. The two ends of each vertical wall 13 of the electrical connector 100C are integrally connected to the upper and lower side walls 11 and 12 respectively. The upper side wall 11 is provided with two upper holes 114, which penetrate the upper side wall up and down and connect to the terminal slot 14, and the two upper holes are arranged front to back. The lower side wall 12 is provided with two lower holes 124 arranged front to back, which penetrate the lower side wall up and down and connect to the terminal slot 14. The upper and lower holes and the corresponding terminal slots 14 form a heat dissipation air channel B3 that is connected up and down. As can be seen from the figure, the lateral width of the upper and lower holes is smaller than the width of the terminal slot.

[0054] Figure 12-13 The fourth embodiment of the present invention is shown, and the structure of its docking connector is the same as that of the first embodiment, mainly in that the air circulation channel of the electrical connector is slightly different. The upper side wall 11 of the electrical connector 100D is provided with an upper hole 115 that penetrates upward, and the upper hole 115 extends backward until it is connected to the terminal slot 14. The lower side wall 12 is provided with a lower hole 125 that penetrates downward, and the lower hole extends backward until it is connected to the terminal slot 14. The upper and lower holes 115, 125 form a heat dissipation air channel B4 that is connected from top to bottom with the corresponding terminal slot 14. The lateral width of the upper and lower holes 114, 124 is approximately the same as the width of the terminal slot. By Fig.13 It can be seen that the portion of the terminal slot 14 close to the rear end of the docking portion is opened at a greater height, so that it is exactly orthogonal to the upper and lower holes, thereby forming an opening 1151 .

[0055] Figure 14-15The fifth embodiment of the present invention is shown, and the structure of its docking connector is the same as that of the first embodiment, mainly in that the air circulation channel of the electrical connector is slightly different. The upper side wall of the electrical connector 100E is provided with an upper hole 116 that penetrates upward, and the upper hole penetrates downward near the front end surface and communicates with the terminal slot 14. The lower side wall is provided with a lower hole 126 that penetrates downward, and the lower hole penetrates downward near the front end surface and communicates with the terminal slot 14. The upper and lower holes and the corresponding terminal slots form a heat dissipation air channel B5 that is connected from top to bottom. The lateral width of the upper and lower holes is approximately the same as the width of the terminal slot. By Fig.15 It can be seen that the terminal slot 14 penetrates forward through the front end surface, and the upper and lower side walls are provided with notches 1161 at the front end surface of the docking portion, so that after the two connectors are docked, the notches and the upper and lower holes and the terminal slot can form an air passage.

[0056] Fig.16 The terminal 20 structure of the electrical connector of the present invention is shown. The terminal includes a plate-shaped fixing portion 23, a contact portion 21 extending forward from the fixing portion 23, and a connecting portion 22 extending backward from the fixing portion. The connecting portion 22 is an embracing structure for connecting cables. The contact portion 21 includes a first elastic portion 211 and a second elastic portion 212. The two elastic portions are opposite to each other and are used to clamp the sheet-shaped terminal 40 of the inserted docking connector 300. Figure 2 The connecting parts 22 of adjacent terminals are arranged vertically, and the contact parts 21 are arranged horizontally, thus saving space at the rear end of the insulating body.

[0057] Figure 17-18 The specific structure of the docking connector 300 is shown, the blade terminal 40 and the through hole 321 are aligned in the vertical direction, and the blade terminal is provided with a needle terminal 50 on the side, and the needle terminals are arranged in a matrix. The inner wall surface of the left and right side walls is provided with a semi-cylindrical guide hole 311.
