[0027] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0028] See attached Figure 2-4 As shown, a knife 200 of this embodiment includes a knife base 210, and a plurality of knife columns 220 are arranged on the top of the knife base 210. The top of each knife column 220 is provided with a spike-shaped vertex 221 for piercing the outer wall of the cable 500. The plurality of spike-shaped vertices 221 are located in the middle, left and right sides of the bottom of the cable 500 to be pierced. The cable 500 is pierced through the spike-shaped vertices 221 and contacts with the conductor inside the cable 500. Even if the cable has a large diameter, there is always a part of the spike-shaped vertices 221 that can pierce the cable and contact with the conductor inside it to achieve transmission.

[0029] There are many ways to implement the spike-shaped vertices 221 located in the middle, left, and right sides of the bottom of the cable 500:

[0030] In a first implementation method, multiple knife columns 220 can be arranged side by side, and the central axis of each spike-shaped vertex 221 is tilted in different directions, including a direction S1 perpendicular to the horizontal plane, a direction S2 tilted to the upper left, and a direction S3 tilted to the upper right.

[0031] The second implementation method is Figure 3 、 4 As shown, multiple knife columns 220 are arranged in multiple rows, and the central axes of the spike-shaped apexes 221 are perpendicular to the horizontal plane or inclined in different directions, including the direction S1 perpendicular to the horizontal plane, the direction S2 inclined to the upper left, and the direction S3 inclined to the upper right.

[0032] The blade 200 is used to connect to the PCB. A fisheye-shaped connection mechanism 211 is located below the blade base 210. This fisheye connection mechanism 211, located at the PCB connection point, effectively ensures connection stability and eliminates the problem of unstable connections with traditional connectors, requiring soldering and thus indirectly polluting the environment.

[0033] During use, the cable can be pulled by external forces, easily causing the blade to be pulled out, resulting in the base of the blade 200 losing its stable connection with the PCB. Therefore, limit points 212 are provided on both sides of the blade base 210, located above the fisheye-shaped connection mechanism 211. Correspondingly, corresponding clearance slots are installed on the terminal block. During actual use, these limit points ensure that the blade does not experience an abnormal phenomenon of unstable connection due to external forces pulling on the cable, thereby ensuring stable and effective data transmission.

The card knives 200 are provided with a plurality of card knives. The terminal block 320 is provided with a card knife through hole 321 for the card knife 200 to pass through. The lower end of the card knife through hole 321 is provided with a clearance groove 322 corresponding to the limit card point 212. The card knife 200 passes through the card knife through hole 321, and the limit card point 212 is clamped in the clearance groove 322. Figure 8 As shown, multiple fisheye hole-shaped connection mechanisms 211 are connected to the PCB board 330 to achieve signal connection. Figure 6 As shown, the wire cover 310 is provided with a wire hole 311 and a wire pressing groove 312. Figure 6 、 8 As shown, the spike-shaped apex 221 of one part of the clamping knife 200 is aligned with the bottom of the cable 500 pressed through the wire pressing groove 312, and the spike-shaped apex 221 of another part of the clamping knife 200 is aligned with the bottom of the cable 500 passed through the wire hole 311.

[0035] Since the knife in the electrical plug connector 300 adopts the aforementioned knife 200, the knife 200 of the electrical plug connector 300 can pierce the cable 500 from multiple directions, and the multiple spike-like vertices 221 can form a wavy line, ensuring that when cables 500 of different wire diameters are used in different models of electrical plug connectors 300, the knife 200 can still pierce normally, thereby ensuring stable and effective transmission of data signals, and indirectly extending the service life of the electrical plug connector 300.

[0036] like Figure 10-13As shown, an electrical plug connector female socket 400 includes the card knife 200 of claim 5 and a wire cover 410, a terminal seat 420, and a PCB board 430 arranged in sequence from top to bottom. The card knife 200 is provided with multiple, and a card knife through hole 421 is provided on the terminal seat 420 for the card knife 200 to pass through. The lower end of the card knife through hole 421 is provided with a clearance groove 422 corresponding to the limit card point 212. The card knife 200 passes through the card knife through hole 421, and the limit card point 212 is clamped in the clearance groove 422. Multiple fisheye hole-shaped connecting mechanisms 211 are connected to the PCB board 430. The wire cover 410 is provided with a wire passing hole 411 and a wire pressing groove 412, wherein the spike-shaped apex 221 of a part of the card knife 200 is aligned with the bottom of the cable 500 pressed through the wire pressing groove 412, and the spike-shaped apex 221 of the other part of the card knife 200 is aligned with the bottom of the cable 500 passing through the wire passing hole 411. Similarly, since the knife in the electrical plug connector socket 400 adopts the above-mentioned knife 200, the knife 200 of the electrical plug connector socket 400 can pierce the cable 500 from multiple directions, and multiple spike-like vertices 221 can form a wavy line, ensuring that when cables 500 of different wire diameters are used in different models of electrical plug connector sockets 400, the knife 200 can pierce normally, ensuring stable and effective transmission of data signals, and indirectly enhancing the service life of the electrical plug connector socket 400.
