A conventional electrical connector includes a base and a conductive terminal assembled into the base. The conductive terminal includes a base, an upper spring arm and a lower spring arm. The base has a plate structure. The upper spring arm is connected to the upper end of the base. The upper spring arm is provided with an upper contact portion for abutting a first mating element. The lower spring arm is connected to the lower end of the base. The lower spring arm is provided with a lower contact portion for abutting a second mating element.

[0003] However, the conductive terminal composed of only a base, an upper spring arm and a lower spring arm in the prior art has only one signal transmission channel when used as a signal terminal. The impedance of the signal terminal is high, which is not conducive to high-speed signal transmission and is difficult to meet the performance requirements of transmitting high-frequency signals. When used as a power terminal, the conductive terminal has only one current transmission channel, which cannot meet the current transmission requirements of large current.

[0004] Therefore, it is necessary to design an electrical connector with a plurality of channels of a conductive terminal to solve the above technical problems. SUMMARY

The interference protrusion 257 is protruded forward from the front edge 2511 of the flat plate portion 251, so as to interfere with the slot wall of the terminal slot 11 for fixation, on the same side of the base portion 21, the interference protrusion 257 is arranged corresponding to the spacing portion 256 and the connecting portion 252 in the front-rear direction, so as to increase the strength of the interference protrusion 257, thereby increasing the stability of the connection between the conductive terminal 2 and the terminal slot 11.

[0048] As FIG. 3 , FIG. 5 and FIG. 7As shown, the two protrusions 26 are connected to the upper and lower ends of the spacing portion 256, and the protrusions 26 have a front side edge 261 and a rear side edge 262 in the front-rear direction, the front side edge 261 does not exceed the front edge 2511 of the extension portion 25 in the front direction, and the rear side edge 262 does not exceed the rear edge 2512 of the extension portion 25 in the rear direction, so that when the conductive terminal 2 is assembled into the terminal groove 11, the protrusions 26 can avoid friction with the groove wall of the terminal groove 11 to affect the assembly of the conductive terminal 2. The upper protrusion 26 is used for abutting with the upper abutting arm 24 on the same side of the base 21, and the lower protrusion 26 is used for abutting with the lower abutting arm 29 on the same side of the base 21.

[0049] In summary, the electric connector of the present application has the following beneficial effects:

[0050] (1) The conductive terminal 2 in the present application is provided with the upper abutting arm 24, which is bent and extended forward and downward from the upper elastic arm 22 to form an upper abutting arm 24, which is used for abutting with the protrusions 26 upward and downward, thereby increasing the transmission channel of the conductive terminal 2. When the conductive terminal 2 is used as a signal terminal, increasing the transmission channel can reduce the overall impedance of the signal terminal to meet the performance requirements of transmitting high-frequency signals. At the same time, the upper abutting arm 24 is lower than the upper contact portion 23 in the upward-downward direction, which reduces the mutual capacity effect of the upper abutting arm 24 and the first mating element 200. When the conductive terminal 2 is used as a power terminal, increasing the transmission channel can improve the current-carrying capacity of the power terminal, thereby facilitating the transmission of large current. At the same time, the upper abutting arm 24 is lower than the upper contact portion 23 in the upward-downward direction, which can increase the spacing between the upper abutting arm 24 and the upper contact portion 23, thereby increasing the heat dissipation efficiency of the conductive terminal 2 and facilitating the transmission of large current.

[0051] (2) The upper elastic arm 22 includes a first arm 2a and a second arm 2b, and a bending portion 2c is formed between the first arm 2a and the second arm 2b. When the conductive terminal 2 is mated with the first mating element 200, the first arm 2a and the second arm 2b are deformed respectively, and the two deformations can increase the elasticity of the conductive terminal 2 while meeting the requirement of the positive force. The upper abutting arm 24 includes a first connecting segment 2d, a second connecting segment 2e, and an abutting segment 2f. The first connecting segment 2d is connected to one side of the second arm 2b in the left-right direction, which facilitates the direct punching of the first connecting segment 2d and the second arm 2b from a metal plate, is conducive to the manufacture of the conductive terminal 2, and can save metal plate materials. The second connecting segment 2e extends forward from the front end of the first connecting segment 2d, and the abutting segment 2f extends downward and rearward from the front end of the second connecting segment 2e. The forward extension and then the downward and rearward bending extension can increase the length of the entire upper abutting arm 24 to increase the elasticity of the upper abutting arm 24. When the conductive terminal 2 is used as a power terminal, increasing the length of the upper abutting arm 24 can also increase the heat dissipation area of the conductive terminal 2, which is conducive to the transmission of larger current.

[0052] (3) The upper abutting arms 24 are connected to the left and right sides of the second arm 2b, and the upper abutting arm 24 on one side of the upper elastic arm 22 abuts against the protruding part 26 on the same side of the upper elastic arm 22, which can further increase the transmission channel of the conductive terminal 2. When the conductive terminal 2 is used as a signal terminal, increasing the transmission channel can reduce the impedance of the signal terminal to meet the performance requirements of transmitting high-frequency signals. When the conductive terminal 2 is used as a power terminal, increasing the transmission channel can improve the current-carrying capacity of the power terminal, thereby facilitating the transmission of large current. At the same time, the extension parts 25 connected to the left and right sides of the base 21 can increase the area of the power terminal as a whole, increase the heat dissipation efficiency of the power terminal, and be more conducive to the transmission of large current.

[0053] (4) The sum of the widths of the two first connecting sections 2d and the parts corresponding to the two first connecting sections 2d on the second arm 2b in the left-right direction is greater than the width of the first arm 2a in the left-right direction, thereby increasing the width of the conductive terminal 2 in the left-right direction. When the conductive terminal 2 is used as a signal terminal, widening the width of the signal terminal in the left-right direction can reduce the impedance of the signal terminal. When the conductive terminal 2 is used as a power terminal, widening the width of the power terminal in the left-right direction can increase the current-carrying capacity, thereby facilitating the transmission of large current.

[0054] (5) The width of the first arm 2a in the left-right direction gradually narrows from the base 21 to the second arm 2b, thereby making room for the extension parts 25 on both sides, facilitating the manufacture of the extension parts 25, and also reducing the rigidity of the first arm 2a, thereby increasing the elasticity of the conductive terminal 2. The width of the second arm 2b in the left-right direction is greater than the width of the upper contact part 23 in the left-right direction. When used as a power terminal, the wider width of the second arm 2b can increase the current-carrying capacity of the power terminal, thereby facilitating the transmission of large current. The narrower width of the upper contact part 23 can make it more stable to butt against the first butt element 200.

[0055] (6) The protruding part 26 is connected to the middle part of the extension part 25 in the up-down direction. The extension part 25 is provided with a connecting part 253 at one end in the up-down direction for connecting the material belt, facilitating the stamping and assembly of multiple conductive terminals 2. The other end is provided with a guide part 254 for guiding the assembly of the conductive terminal 2 to the corresponding terminal slot 11.

[0056] (7) At least one side of the extension part 25 in the front-back direction interferes with the slot wall of the corresponding terminal slot 11, fixing the conductive terminal 2 to the base 1. The front side edge 261 of the protruding part 26 does not exceed the front edge 2511 of the extension part 25, and the rear side edge 262 of the protruding part 26 does not exceed the rear edge 2512 of the extension part 25, thereby avoiding the friction between the protruding part 26 and the slot wall of the terminal slot 11 affecting the assembly of the conductive terminal 2 when the conductive terminal 2 is assembled into the terminal slot 11. The protruding part 26 that does not contact the slot wall of the terminal slot 11 has better elasticity.

[0057] (8) On the same side of the upper arm 22 in the left-right direction, the upper abutting arm 24 and the corresponding extension 25 have a gap, so that when the upper contact 23 is pressed by the first mating element 200, the upper abutting arm 24 and the corresponding extension 25 are not in contact, thereby avoiding the friction between the upper abutting arm 24 and the extension 25, affecting the compression and rebound of the upper abutting arm 24; the upper abutting arm 24 extends forward no more than the front edge 2511 of the extension 25, and the upper abutting arm 24 extends backward no more than the base 21, thereby avoiding the friction between the upper abutting arm 24 and the groove wall of the terminal groove 11, affecting the compression and rebound of the upper abutting arm 24, so that the upper abutting arm 24 is more smooth in compression and rebound.

[0058] (9) The conductive terminal 2 is also provided with a lower spring arm 27 and a lower abutting arm 29 connected to the left and right sides of the lower spring arm 27, the lower abutting arm 29 abuts the protruding part 26, which can further increase the transmission path of the conductive terminal 2 and increase the current carrying capacity of the conductive terminal 2. Each extension 25 is correspondingly provided with two protruding parts 26 arranged in upper and lower positions, the upper protruding part 26 corresponds to the abutting of the upper abutting arm 24, and the lower protruding part 26 corresponds to the abutting of the lower abutting arm 29, so that the upper abutting arm 24 and the lower abutting arm 29 do not interfere with each other and abut to the respective protruding part 26. When the conductive terminal 2 is used as a power terminal, abutting to different protruding parts 26 can increase the heat dissipation area, which is beneficial to the transmission of large current by the conductive terminal 2.

[0059] (10) The metal plate where the extension 25 is located is formed into two protruding parts 26, thereby forming two grooves 255 and a spacing part 256, which can make more full use of the metal plate. The two grooves 255 are spaced apart by the spacing part 256, and the two protruding parts 26 are connected to the upper and lower ends of the spacing part 256. When the conductive terminal 2 is used as a power terminal, compared with the scheme of providing one protruding part 26, the two protruding parts 26 are spaced apart to facilitate heat dissipation of the power terminal. Compared with the scheme of providing the protruding part 26 above the groove 255, the protruding part 26 of the present scheme is relatively close, which can reduce the current transmission path.

[0060] (11) The interference protrusion 257 protruding from the front side of the extension 25 is correspondingly arranged in the front-rear direction with the spacing part 256 and the connecting part 252, which can increase the strength of the interference protrusion 257 in the front-rear direction, so that the interference protrusion 257 and the groove wall of the terminal groove 11 are more stably fixed together, thereby increasing the stability of the conductive terminal 2 in the terminal groove 11.

[0061] (12) The conductive terminal 2 is arranged symmetrically left and right, and the upper and lower parts of the conductive terminal 2 on the base 21 are symmetrically arranged, so as to ensure that the normal forces on the upper and lower sides of the conductive terminal 2 are consistent, and the forces on the upper and lower ends of the conductive terminal 2 are more uniform.

[0062] (13) The base 1 is provided with at least one limiting portion 12 on the inner wall of the terminal groove 11. Each extension portion 25 comprises a flat plate portion 251 extending in the front-rear direction and a connecting portion 252 connected between the extension portion 25 and the base portion 21. The conductive terminal 2 is assembled in the terminal groove 11 in the up-down direction. The connecting portion 252 is limited on one side of the limiting portion 12 in the up-down direction and is blocked by the limiting portion 12, so that the conductive terminal 2 is kept stable in the up-down direction.

[0063] The above detailed description is only a description of the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Therefore, any equivalent technical changes made according to the content of the present application description and drawings are included in the patent scope of the present application.
