The first terminal 100 is limited and fixed in the insulating base 300, and the first terminal 100 extends from the outer end of the first channel 330 into the first channel 330.

[0057] The first terminal 100 may include a bent section 110. One end of the first terminal 100 passing through the first channel 330 is bent toward the second channel 340 to form the bent section 110.

[0060] The electronic connector may further include a second terminal 200, which is detachably inserted into the second channel 340; the free end of the bent section 110 abuts against the second terminal 200, so that the first terminal 100 and the second terminal 200 are electrically connected.

[0063] It should be noted that, in this embodiment, the first terminal 100 and the second terminal 200 are both wiring structures. In one embodiment, the first terminal 100 and the second terminal 200 are both single wires.

[0064] In one embodiment, the first terminal 100 is a plurality of pin headers, which are arranged at intervals. The second terminal 200 is an FFC cable, which is arranged at intervals.

[0066] The angle between the free section of the bending section 110 and the second terminal 200 is an acute angle.

[0067] In a specific embodiment, the angle between the free end of the bent section and the second terminal 200 is 3-8 degrees.

[0073] The first channel 330 is formed with a recessed groove 331 near its inner end, and the recessed groove 331 is located on the side of the first terminal 100 facing away from the second channel. When the second terminal 200 is inserted into the second channel 340 and presses the bent section 110, the second terminal 200 can be deformed toward the recessed groove 331 to facilitate the insertion of the second terminal 200 on the insulating base 300.

[0074] In this embodiment, the insulating base 300 includes a first fixing block 310 and a second fixing block 320 which are arranged opposite to each other. The portion of the first fixing block 310 facing the first protruding portion 311 is concave to form a groove 331 .

[0075] In this embodiment, one end of the second terminal 200 extending into the second channel 340 abuts against the inner end side wall of the second channel 340, and the free end of the bent section 110 abuts against the end of one end of the second terminal 200 extending into the second channel 340, so that after the second terminal 200 and the bent section 110 abut against each other, no excess part (residual stump 10) will extend out, and no excess part exists on the first terminal 100 and the second terminal 200, thereby ensuring the stability and consistency of the impedance between the first terminal 100 and the second terminal 200.

[0076] The second channel 340 extends in a straight line, and one end of the second terminal 200 extending into the first channel 330 extends in a straight line to facilitate the insertion and separation of the second terminal 200 in the second channel 340 .

The clamping plate 360 ​​is rotatably connected to the second fixed block 320 and can be detachably engaged with the first fixed block 310 or the second fixed block 320 to press and limit the second terminal 200 on the first fixed block 310.

[0084] The side of the clamping plate 360 ​​facing the first fixing block protrudes to form a step portion 361. When the clamping plate is clamped on the first fixing block 310 or the second fixing block 320, the step portion 361 abuts against the second terminal to keep the second terminal 200 pressed tightly.

[0085] The second fixing block 320 is provided with a connecting member 370, and the connecting member 370 is used to connect the clamping plate 360 ​​and the second fixing block 320. The clamping plate 360 ​​is rotatably connected to the connecting member 370.

[0086] In one embodiment, the insulating base 300 is not provided with a clamping plate 360 ​​, and an elastic structure is provided in the second channel 340 . After the second terminal 200 extends into the second channel 340 , the elastic structure is pressed on the second terminal 200 to keep the second terminal 200 limited on the insulating base 300 .

[0087] Based on the above technology, the first terminal 100 is embedded in the insulating base 300. When the second terminal 200 is inserted into the insulating base 300, the card plate 360 ​​is opened, and the second terminal 200 faces one end of the insulating base 300 and extends into the second channel 340 from the outer end opening of the second channel 340. The second terminal 200 is moved so that the end of the second terminal 200 extending into the second channel 340 moves to a preset position in the second channel 340, so that the end of the second terminal 200 abuts against the side wall of the second channel 340. The second terminal 200 squeezes the bending section to deform, so that the end of the second terminal 200 and the end of the bending section 110 abut against each other. The card plate 360 ​​is pressed to move the card plate 360 ​​toward the first fixed block 310, and the card plate 360 ​​is pressed on the second terminal 200, and is clamped on the first fixed block 310 and the fixed block.

The second terminal 200 is detachably arranged in the second channel 340; the free end of the bending section 110 abuts against the second terminal 200, so that the first terminal 100 and the second terminal 200 are conductive.
