The plug-in slot 21 passes through the first support portion 22 and the second support portion 24. The first support portion 22 is closer to the entrance of the plug-in slot 21 than the second support portion 24. Specifically, the first support portion 22 is a first rectangular tube, and the second support portion 24 is a second rectangular tube. The inner cavity of the first rectangular tube is opposite to the inner cavity of the second rectangular tube, and the inner cavity of the first rectangular tube is the entrance of the plug-in slot 21.

Secondly, the first cantilever structure 42 and the second cantilever structure 44 are respectively more easily deformed to form a better contact with the mating terminal to achieve transmission of a larger current. Therefore, the connector terminal 100 is not only simple in structure and low in manufacturing cost, but also can meet the requirements of large current transmission.

[0043] The first support portion 22 includes two opposite first side plates 221 and two opposite first end plates 223, wherein a pair of cantilever structures are respectively connected to the sides of the two first side plates 221 facing the second support portion 24, and one of the pair of cantilever structures is located in the avoidance space 23.

In this embodiment, the contact portion 40 includes at least one pair of elastic first cantilever structures 42 and at least one pair of elastic second cantilever structures 44, the same ends of the pair of first cantilever structures 42 are respectively connected to the first support portion 22, one end of the pair of first cantilever structures 42 away from the first support portion 22 is located in the avoidance space 23, and a first clamping gap 427 is provided between the pair of first cantilever structures 42; the same ends of the pair of second cantilever structures 44 are respectively connected to the second support portion 24, one end of the pair of second cantilever structures 44 away from the second support portion 24 is located in the avoidance space 23, and a second clamping gap 447 is provided between the pair of second cantilever structures 44. Specifically, at least one pair of first cantilever structures 42 are respectively connected to the two first side plates 221 of the first support portion 22 facing the side of the second support portion 24, and one end of the pair of first cantilever structures 42 away from the first support portion 22 is accommodated in the plug-in slot 21; at least one pair of second cantilever structures 44 are respectively connected to the two second side plates 241 of the second support portion 24 facing the side of the first support portion 22, and one end of the pair of second cantilever structures 44 away from the second support portion 24 is accommodated in the plug-in slot 21.

[0044] In this embodiment, the contact portion 40 includes two pairs of first cantilever structures 42, the two pairs of first cantilever structures 42 are respectively connected to the two first side plates 221 of the first support portion 22, the two pairs of first cantilever structures 42 are arranged at intervals from each other along the length direction of the first side plate 221, and each pair of first cantilever structures 42 are symmetrically arranged up and down; the second cantilever structure includes two pairs of second cantilever structures 44, the two pairs of second cantilever structures 44 are respectively connected to the two second side plates 241 of the second support portion 24, the two second cantilever structures 44 are arranged at intervals from each other along the length direction of the second side plate 241, and each pair of second cantilever structures 44 are symmetrically arranged up and down.

[0045] Optionally, the contact portion 40 may include more than two pairs of first cantilever structures 42, which are arranged at intervals along the width direction of the plug-in slot 21, so that a single first cantilever structure 42 is more easily deformed and forms a better contact with the mating terminal, thereby achieving transmission of a larger current; the contact portion 40 may include more than two pairs of second cantilever structures 44, which are arranged at intervals along the width direction of the plug-in slot 21, so that a single second cantilever structure 44 is more easily deformed and forms a better contact with the mating terminal, thereby achieving transmission of a larger current. In this embodiment, the contact portion 40 includes two pairs of first cantilever structures 42 and two pairs of second cantilever structures 44. The two pairs of first cantilever structures 42 are respectively connected to the two first side plates 221 of the first support portion 22, and the two pairs of first cantilever structures 42 are arranged at intervals from each other along the width direction of the plug-in slot 21. The two pairs of second cantilever structures 44 are respectively connected to the two second side plates 241 of the second support portion 24, and the two second cantilever structures 44 are arranged at intervals from each other along the width direction of the plug-in slot 21.

[0046] Optionally, the number of logarithms of the first cantilever structures 42 of the contact portion 40 is greater than or equal to the number of logarithms of the second cantilever structures 44, so that multiple pairs of first cantilever structures 42 with shorter cantilevers can also obtain elastic forces equal to or similar to multiple pairs of first cantilever structures 42 with longer cantilevers. Preferably, the number of logarithms of the first cantilever structures 42 of the contact portion 40 is greater than the number of logarithms of the second cantilever structures 44; for example, the contact portion 40 includes three pairs of first cantilever structures 42 and two pairs of second cantilever structures 44, the contact portion 40 includes four pairs of first cantilever structures 42 and three pairs of second cantilever structures 44, or the contact portion 40 includes four pairs of first cantilever structures 42 and two pairs of second cantilever structures 44, etc.

[0047] In other embodiments, the contact portion 40 includes more than three pairs of first cantilever structures 42, which are respectively connected to the two first side plates 221 of the first support portion 22, and the three or more pairs of first cantilever structures 42 are arranged at intervals from each other along the length direction of the first side plate 221; the contact portion 40 includes more than three pairs of second cantilever structures 44, which are respectively connected to the two second side plates 241 of the second support portion 24, and the three or more pairs of second cantilever structures 44 are arranged at intervals from each other along the length direction of the second side plate 241.

[0048] like Figure 3 and Figure 4As shown, the first cantilever structure 42 includes a first cantilever 422, a first contact 424 and a first end 426. One end of the first cantilever 422 is connected to a side of the first support portion 22 close to the second support portion 24, and the other end of the first cantilever 422 is inclined toward the side of the second support portion 24 and extends to the plug slot 21. The first contact 424 is located at an end of the first cantilever 422 away from the first support portion 22, and the first end 426 is connected to the first contact 424. The first end 426 is inclined toward a side away from the first cantilever 422 and the plug slot 21. A first clamping gap 424 is formed between the first contacts 424 of the pair of first cantilever structures 42. 7; The second cantilever structure 44 includes a second cantilever 442, a second contact 444 and a second end 446, one end of the second cantilever 442 is connected to the side of the second support portion 24 close to the first support portion 22, and the other end of the second cantilever 442 is inclined toward the side of the first support portion 22 and extends to the plug-in slot 21, the second contact 444 is located at the end of the second cantilever 442 away from the second support portion 24, the second end 446 is connected to the second contact 444, and the second end 446 is inclined toward the side away from the second cantilever 442 and the plug-in slot 21, and a second clamping gap 447 is provided between the second contacts 444 of a pair of second cantilever structures 44. Specifically, the first cantilever 422 is an elastic inclined sheet, and the ends of the first cantilevers 422 of a pair of first cantilever structures 42 away from the first contact 424 are respectively connected to the two first side plates 221 of the first support portion 22 facing the side of the second support portion 24, and the first cantilever 422 is inclined toward the plug-in slot 21, so that the first contact 424 and the first end 426 are accommodated in the plug-in slot 21; the second cantilever 442 is an elastic inclined sheet, and the ends of the second cantilevers 442 of a pair of second cantilever structures 44 away from the second contact 444 are respectively connected to the two second side plates 241 of the second support portion 24 facing the side of the first support portion 22, and the second cantilever 442 is inclined toward the plug-in slot 21, so that the second contact 444 and the second end 446 are accommodated in the plug-in slot 21.

[0049] In other embodiments, the first cantilever 422 may be, but is not limited to, an elastic arc-shaped piece, etc., and the second cantilever structure 44 may be, but is not limited to, an elastic arc-shaped piece, etc.

[0050] Optionally, the length of the first cantilever structure 42 extending along the length direction of the plug slot 21 is less than the length of the second cantilever structure 44 extending along the length direction of the plug slot 21, so that the contact portion 40 can be close to the entrance of the plug slot 21, so that the connector terminal 100 obtains a shorter coupling height when coupled with the mating terminal, thereby reducing the height of the connector provided with the connector terminal 100, which is convenient for miniaturization of the connector. Specifically, the length of the first cantilever 422 extending along the length direction of the plug slot 21 is less than the length of the second cantilever 442 extending along the length direction of the plug slot 21. In other embodiments, the length of the first cantilever structure 42 extending along the length direction of the plug slot 21 is equal to or greater than the length of the second cantilever structure 44 extending along the length direction of the plug slot 21.

[0051] Optionally, the first clamping gap 427 is directly opposite to the second clamping gap 447, and the spacing L1 of the first clamping gap 427 is equal to or not equal to the spacing L2 of the second clamping gap 447; in this embodiment, the spacing L1 of the first clamping gap 427 is greater than or equal to the spacing L2 of the second clamping gap 447. The spacing L1 of the first clamping gap 427 is at the mouth of the connector terminal 100. When the spacing L1 is greater than the spacing L2, the spacing L1 will not block the spacing L2, which is convenient for measuring the size of the spacing L2; in addition, the first cantilever structure 42 is set smaller than the second cantilever structure 44, that is, the length of the first cantilever 422 is smaller than the length of the second cantilever 442, so as to reduce the coupling height. Since the first cantilever 422 is shorter, the spacing L1 is set slightly larger than the spacing L2, so that the positive pressure of the first contact 424 of the first cantilever structure 42 is close to the positive pressure of the second contact 444 of the second cantilever structure 44, so that the contact points are in reliable contact and can facilitate the plugging and unplugging of the mating terminals.

[0052] Optionally, the angle a between the first ends 426 of the pair of first cantilever structures 42 is smaller than the angle b between the second ends 446 of the pair of second cantilever structures 44, and the radial dimension formed by the angle b between the second ends 446 of the second cantilever structures 44 is larger than the radial dimension of the terminal to be matched, so that the matching terminal can be smoothly matched and coupled with the connector terminal 100. In other embodiments, the angle a between the first ends 426 of the pair of first cantilever structures 42 is equal to the angle b between the second ends 446 of the pair of second cantilever structures 44; or the angle a between the first ends 426 of the pair of first cantilever structures 42 is larger than the angle b between the second ends 446 of the pair of second cantilever structures 44.

[0053] like Figure 2-Figure 4As shown, the second support portion 24 is provided with a barb 240 for fixing the connector terminal 100 to the connector core. In this embodiment, the outer surface of one of the second end plates 243 of the second support portion 24 is provided with a barb 240. In other embodiments, the outer surfaces of the two second end plates 243 of the second support portion 24 are respectively provided with a barb 240. The second support portion is provided with a convex point 245, which is slightly higher than the outer surface of the second support portion 24. The convex point 245 is used to cooperate with the connector core to form an interference fit, so that the connector terminal 100 can be placed in the center of the connector core; the outer surface of at least one second side plate 241 of the second support portion 24 is provided with a convex point 245. In this embodiment, the middle of the outer surface of the two second side plates 241 of the second support portion 24 is respectively provided with a convex point 245, so that the connector terminal 100 is placed in the center of the connector core. The main body 20 also includes a cover plate 27, which is connected to one end of the second support portion 24 away from the first support portion 22, and the cover plate 27 covers the plug-in slot 21. Since the cover plate 27 is tightly fitted with the tail plane of the second support portion 24 to cover the plug-in slot 21, the cover plate 27 can prevent the connector terminal 100 from leaking glue when the tail is glued or coated, thereby preventing glue from flowing into the plug-in slot 21.

[0054] The connector terminal 100 is formed into an integral structure by stamping a plate of the same thickness, so the thickness of the first support portion 22, the thickness of the second support portion 24, the thickness of the connecting strip 26, the thickness of the first cantilever structure 42, the thickness of the second cantilever structure 44 and the thickness of the connecting portion 60 are consistent. In other embodiments, the thickness of the connector terminal 100 gradually becomes thinner from the connecting portion 60 to the first support portion 22 to increase the elastic force of the first cantilever structure 42 and the second cantilever structure 44, so that the connector terminal 100 can be stably plugged with the mating terminal.

[0055] The connecting portion 60 is used to achieve electrical connection between the connector terminal 100 and the wire. In this embodiment, the connecting portion 60 is a connecting plate connected to the second support portion 24. The wire is placed on the connecting plate and fixedly connected to the connecting portion 60 by processes such as ultrasonic welding.

[0056] like Figure 5 As shown, in one embodiment of the connection portion 60 of the connector terminal 100 and the wire, a screw hole 62 is provided on the connection portion 60 , and the wire is screwed into the screw hole 62 by a screw, so that the wire is fixedly connected to the connection portion 60 .

[0057] like Figure 6 As shown, the connection portion 60 of the connector terminal 100 is configured as a wire barrel 64, and the wire is fixedly connected to the wire barrel 64 by a crimping process, so that the wire is fixedly connected to the connection portion 60. In other embodiments, the connection portion 60 can be configured as a wire pin, and the wire is fixedly connected to the wire pin by a crimping process.

[0058] like Figure 7 As shown, the connector terminal 100 is integrally formed. The initial contours of the first cantilever structure 42, the second cantilever structure 44, the cover plate 27, the connecting portion 60 and other parts are first formed on the plate by stamping and / or cutting. Cantilever bending is performed at C1, C2, C3, and C4 on the plate to form the first cantilever structure 42 and the second cantilever structure 44. The plate is bent along the portions marked as B1, B2, B3, and B4 to form the four corner bends of the rectangular cross-section of the connector terminal 100; the portion D on the plate is bent to form the cover plate 27.

[0059] Please also read Figure 8-Figure 11 The structure of the connector terminal 100a provided in the second embodiment of the present invention is similar to the structure of the connector terminal 100 provided in the first embodiment, except that the arrangement of the two pairs of cantilever structures of the connector terminal 100a in the second embodiment on the main body is different from the arrangement of the two pairs of cantilever structures of the connector terminal 100 in the first embodiment on the main body.
