[0053] The following will elaborate on the preferred embodiments of the present invention in conjunction with 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 the protection scope of the present invention more clearly defined.

[0054] Refer to the attached Figure 1 、 Figure 2 As shown, a female socket of an electrical plug connector in this embodiment includes a female socket body 1 of the electrical plug connector and a socket cover 8 provided on the upper part of the female socket body 1 of the electrical plug connector. A universal pre-buried wire device 6 is installed at one end of the female socket body 1 of the electrical plug connector, and a 90° wire connection assembly or a 180° wire connection assembly is provided in the female socket body 1 of the electrical plug connector. Engineers can select to install a 90° wire connection assembly or a 180° wire connection assembly according to the usage habits of the users, which is convenient for the users' future use.

[0055] Among them, the 90° wire connection assembly includes a 90° universal insert core 21, a first PCB circuit board 31, a puncture-type cutter 71, a first terminal seat 41, and a first wire clamping device 51 that are sequentially arranged in the female socket body 1 of the electrical plug connector. The 90° universal insert core 21 and the puncture-type cutter 71 are connected through the first PCB circuit board 31. At the same time, the puncture-type cutter 71 passes through the first terminal seat 41 and inserts into the cable in the first wire clamping device 51;

[0056] The 180° wire connection assembly includes a 180° universal insert core 22, a second PCB circuit board 32, a cutting-type cutter 72, a second terminal seat 42, and a second wire clamping device 52 that are sequentially arranged in the female socket body 1 of the electrical plug connector. The 180° universal insert core 22 and the cutting-type cutter 72 are connected through the second PCB circuit board 32. At the same time, the cutting-type cutter 72 passes through the second terminal seat 42 and inserts into the cable in the second wire clamping device 52.

[0057] Among them, as Figure 3As shown in Fig. -5, a window 12 is provided on the female socket body 1 of the electrical plug connector, and a dust-proof door mechanism 13 is arranged in the window 12. The window 12 can adopt a closed dust-proof window. The dust-proof door mechanism 3 includes a dust-proof door 131 and a spring mounting hole position 132. The dust-proof door 131 is rotatably arranged on the window 12 through a spring. The top of the dust-proof door 131 and the upper side edge of the closed dust-proof window are both straight edges 133. When the dust-proof door 131 rebounds, the two straight edges 133 are abutted against each other to ensure that the dust-proof door 131 will not pop out of the window 12. The female socket of the electrical plug connector combined with the mechanical structures of the closed dust-proof window and the dust-proof door mechanism 13 can effectively protect the core of the female socket of the electrical plug connector and extend the service life of the core. When the electrical plug connector joint is inserted into the female socket, there is no need to manually open or close the dust-proof door surface. And because the female socket has a closed dust-proof window, it can effectively fix the electrical plug connector joint to ensure the contact between the electrical plug connector joint and the core, and it can also have good connection performance under some extreme usage conditions to ensure the effective transmission of data. When the electrical plug connector plug is pulled out of the female socket, the dust-proof door automatically rebounds, and due to the structural relationship between the closed dust-proof window and the dust-proof door, it will not pop out due to excessive rebound force, so as to ensure continuous and effective protection of the core.

[0058] As Figure 6 shown, the socket cover 8 is provided with a rotating column 81 which is engaged with the rotating slot 14 on the female socket body 1 of the electrical plug connector, so that the socket cover 8 is rotatably arranged on the female socket body 1 of the electrical plug connector. The two sides of the socket cover 8 are provided with upper cover fastening blocks 82 which are fastened with the upper cover fastening slots 15 on both sides of the female socket body 1 of the electrical plug connector. The socket cover 8 is also provided with a semi-circular arc threaded plate 83. On both sides of the female socket body 1 of the electrical plug connector, there are semi-threaded fastener limiting grooves 16, and a terminal seat limiting block 17 is provided on its upper part to limit the position of the terminal seat. In addition, a semi-threaded fastener limiting and guiding groove 18 is also provided on its inner side.

[0059] As Figure 28a 、 28b shown, the semi-threaded fastener 9 includes a clamping part 91 and a semi-circular threaded plate 92 connected to the clamping part 91. The semi-circular threaded plate 92 is matched with the semi-circular arc threaded plate 83 of the socket cover 8 and can be tightened by a fastening nut 64. On both sides of the clamping part 91, there are semi-threaded fastener blocks 93 so that the semi-threaded fastener 9 can be clamped into the semi-threaded fastener limiting groove 16. On both sides of the clamping part 91, there are semi-threaded fastener guiding blocks 94 which can be inserted into the semi-threaded fastener limiting and guiding groove 18 so that the semi-threaded fastener 9 is connected to the female socket body 1 of the electrical plug connector.

[0060] As Figures 7 - 9 、29a-c shown, the universal pre-buried wire device 6 includes a tubular part 61 whose wire routing direction can be changed. The tubular part 61 has a single fold angle, and the fold angle is generally greater than or equal to 90 degrees and less than or equal to 180 degrees (AsFigure 7 It is a tubular member 61 with a 135-degree fold angle. Figure 8 It is a tubular member 61 with a 90-degree fold angle, such as Figure 29a , 29b, 29c are installation diagrams of a 180-degree pre-wire management device, a 45-degree pre-wire management device, and a 90-degree pre-wire management device, respectively), so that the outlet direction of the cables can be changed when passing through, and a channel for the cable routing is provided in the tubular member 61. Wherein, the tubular member 61 is composed of a first shell 611 and a second shell 612 that can be detachably connected. One end of the first shell 611 and the second shell 612 are connected by a pivot, and the other end is buckled to form a channel for the cable routing. In this embodiment, a buckling hinge is used for buckling. The buckling hinge is a snap-fitting portion 613 and a connecting portion that connects the snap-fitting portion to the first shell 611. The snap-fitting portion can be snapped into the inside of the buckling groove 614 on the second shell 612. As shown in the figure, the snap-fitting portion 613 is cylindrical. In order to obtain a better buckling effect, the snap-fitting portion 613 is preferably an irregular ellipse, which can be less likely to fall off after installation. At the same time, the buckle groove 614 is preferably provided with a buckle step 615 to cooperate with the snap-fitting portion 613 to more effectively ensure that the snap-fitting portion 613 does not fall off. The tail end of the tubular member 61 is provided with a connection port 62 for threading, and the first shell 611 and the second shell 612 are both provided with buckles 621 corresponding to the buckle grooves on the wire inlet of the electrical plug connector female socket, which are used to lock the universal pre-wire management device 6 on the wire inlet of the electrical plug connector female socket, so as to realize the function of ensuring the wire management mechanism in four directions of 360 degrees. A threaded fastening device 63 is provided at the head end of the tubular member 61, and the threaded fastening device 63 is a semi-circular upper threaded fastener 631 and a semi-circular lower threaded fastener 632 respectively arranged on the first shell 611 and the second shell 612. By being arranged on a semi-threaded fastener block and a semi-threaded fastener guide block, they are respectively matched with the semi-threaded fastener limiting groove 16 and the semi-threaded fastener limiting guide groove 18 on the electrical plug connector female body 1, so that the universal pre-wire management device 6 can be installed on the electrical plug connector female body 1. The lower threaded fastener 632 and the upper threaded fastener 631 fit each other, and the thread composition located on the mutual fit of the lower threaded fastener 632 and the upper threaded fastener 631 can be used for tightening the external thread of the fastening nut 64, wherein one end of the fastening nut 64 is provided with a contraction slope 641 for positioning. When in use, the semi-threaded fastener 9 and the tubular member 61 are locked on the wire inlet of the female socket of the electrical plug connector, and the position of the tubular member 61 is adjusted, and then the wire clamping mechanism 65 is installed on the tubular member 61, and the lower threaded fastener 632 and the upper threaded fastener 631 are tightened and fixed with the tightening nut 64. The wire clamping mechanism 65 includes an annular base 651, and two wire clamping support columns 652 are arranged on one side of the annular base 651. The outer side of the head of the wire clamping support column 652 is provided with a wire clamping buckle 653. The wire clamping support column 652 and the wire clamping buckle 653 will move toward the middle during the tightening process of the tightening nut 64, thereby clamping the cable and fixing it.

[0061] like Figures 10 - 13As shown, the 90° universal socket core 21 includes a first pin support 211, a first pin support buckle 213, two rows of pins 212a and 212b. Eight first arc-shaped movable support points 214 are provided on the upper part of the first pin support 211 to hold the arc-shaped part between the two ends of the two rows of pins 212a and 212b. And an activity support frame 215 is provided on the upper part of the first pin support 211. One end of the first pin support 211 is provided with a number of first pin slots 2111 for placing pins, into which the ends of the two rows of pins 212a and 212b are snapped. The first pin support buckle 213 is slid into the first pin support 211 through the chutes on both sides of the first pin slot 2111, and the three-way fastening blocks 218 at both ends of the first pin support buckle 213 are snapped into the corresponding three-way fastening slots 219 of the first pin slot 2211 to lock the ends of the two rows of pins 212a and 212b. And the other end is provided with a first slot for the other ends of the two rows of pins 212a and 212b to be snapped into and locked by the activity support frame 215. The first slot and the blocks at both ends of the first pin support buckle 213 are snapped together (in order to enhance the snapping effect, the block can be trapezoidal). Force-relieving edges 217 are provided on both sides of the first pin support 211, which can effectively solve the abnormal phenomena such as the socket core being damaged easily and the contact being unstable due to the socket core being stressed alone when the plug is inserted into the socket core. Four first row pin pressing blocks 2131 and four second row pin pressing blocks 2132 are provided on one side of the first pin support buckle 213, and the four first row pin pressing blocks 2131 and the four second row pin pressing blocks 2132 are arranged at intervals.

[0062] See the appendix Figure 14 As shown, 8 socket core through holes 311 are respectively provided on the first PCB circuit board 31 for the first row and the second row of pins 212a and 212b to be inserted, and 8 cutter through holes 312 are provided for the puncturing cutter 71 to be inserted.

[0063] See the appendix Figure 15 、 16As shown in the figure, the piercing type cutter 71 includes a second cutter body 711, and the upper part of the second cutter body 711 is provided with first, second, and third spiky vertices 712, 713, and 714. The central axes of the first, second, and third spiky vertices 712, 713, and 714 are inclined in different directions. The number of spiky vertices may not be limited to three, at least two are sufficient, and their central axes are inclined in different directions. The tail of the second cutter body 711 adopts a fisheye-shaped through hole 715, which solves the problem that traditional cutters may not be able to cut through cables with different wire diameters during construction, resulting in poor contact and unstable data transmission. Experiments have proved that this universal piercing cutter is suitable for use in various types of electrical plug connectors or female sockets of electrical plug connectors, such as Category 5, Category 6, Super Category 6, Category 7, and Category 8, and can ensure that cables with various wire diameters are normally pierced, data transmission is stable, and the service life of the equipment is enhanced. The two sides of the second cutter body 711 are provided with limit clamping points 716, which are used to provide a hard limit when the piercing type cutter 71 is inserted and connected.

[0064] See the appendix Figure 17 As shown in the figure, eight cutter placement slots 411 are provided on the first terminal block 41, and each cutter placement slot 411 is in the shape of a division sign, so as to be adapted to be universal for a variety of cutters. In order to guide and limit the wire pressing of the universal wire clamping device and reduce the use difficulty, two wire cover limit posts 412 are provided at one end of the first terminal block 41. The upper part of the first terminal block 41 is provided with a terminal block limit block 413, which is used in cooperation with the female seat cover 8 to prevent the terminal block 5 from shifting. Four cable avoidance grooves 414 are provided on the terminal block limit block 413 to avoid cables that are not cut properly during normal construction, thereby improving the practicability of the electrical plug connector.

[0065] See the appendix Figure 18 、 19 As shown in the figure, the first wire clamping device 51 includes a wire cover body 511 (as shown in the figure, for the convenience of threading and managing cables, the wire cover body is preferably L-shaped, but may not be limited to L-shaped). Four cable through holes 512 and four cable pressing grooves 513 are arranged horizontally on the wire cover body 511. First cutter breaking grooves 514 and second cutter breaking grooves 515 for accommodating cutters are respectively arranged in the cable through holes 512 and cable pressing grooves 513. The first cutter breaking groove 514 is in an X shape, and the second cutter breaking groove 515 is in an inclined straight shape, which can be applicable to both the cutting type cutter 71 and / or the piercing type cutter 72 at the same time. A pair of wire pressing blocks 516 are respectively arranged on both sides of the cable pressing groove 513. The number of wire pressing blocks 516 may not be limited to two pairs, at least one pair is sufficient, and two pairs are the best.

[0066] See the appendix Figures 20 - 23As shown, the 180° universal socket core 22 includes a second pin support 221, second and third pin support buckles 223 and 224, and two rows of pins 222a and 222b. The second pin support 221, second and third pin support buckles 223 and 224 are clamped to each other through their own mechanical structures, making the installation of the first row of pins 22a and the second row of pins 22b more stable.

[0067] Specifically, a positioning groove 221a for placing the first row of pins 222a is provided on the second pin support 221. Support columns 2212 are provided on both sides of the positioning groove 221a. Vertical card slots are provided on the opposite side surfaces of the two support columns 2212, and the second pin support buckle 223 is first inserted into the vertical card slots. A positioning groove for placing the second row of pins 222b is provided on the upper end surface of the second pin support buckle 223, and the third pin support buckle 224 is inserted into the vertical card slots to fix the second row of pins 222b. The above-mentioned positioning grooves 221a and 222a are staggered to prevent the two rows of pins 222a and 222b from overlapping each other. The arc-shaped parts between the two ends of the two rows of pins 222a and 222b are abutted against the arc-shaped movable support points 225, so that the two rows of pins 222a and 222b will not be deformed after being stressed; thus enhancing the elasticity and performance of the pins 222a and 222b. Even if one of the pins is stressed and pressed down, it will not affect the normal contact of the other seven pins with the plug of the electrical plug connector, avoiding poor contact caused by the insertion of the plug connector. The tails of the two rows of pins 222a and 222b both adopt fisheye-shaped through holes. Therefore, when connecting to the second PCB circuit board 32, there is no need for a welding process, which not only reduces the production difficulty and cost, but also fundamentally solves the poor contact caused by problems such as missed soldering and false soldering. The service life is improved. Through the joint action of the pin slots, arc-shaped movable support points, and movable mesh support frames, the pins of this socket core are more stable, with good transmission performance and practicability, and avoid poor contact.

[0068] Release edges 2213 are provided on both sides of the second pin support 221, which can effectively solve the abnormal phenomena such as the socket core being easily damaged and the contact being unstable when the plug is inserted into the socket core alone.

[0069] A pressing block 2231 for separating the cables of the first row of pins 222a, an irregular geometric shape limiting card slot 2232, and an avoidance bevel 2233 for avoiding the arc-shaped part of the second row of pins 222b are provided at the lower part of the second pin support buckle 223. A pressing block 2241 for separating the cables of the second row of pins 222b, a second row of pin blocking blocks 2242 for blocking the second row of pins 222b, a crystal head avoidance groove 2244, and a cutter avoidance groove 2245 are provided on the third pin support buckle 224. Third pin support buckle blocks 2243 that are snapped into the vertical card slots are provided on both sides of the third pin support buckle 224.

[0070] See the appendix Figure 24 As shown, 16 RJ45 crystal chip perforations are respectively provided on the second PCB board 32 for inserting RJ45 connectors to connect with two rows of pins 222a and 222b, and 8 cutter perforations are provided for inserting the cutting-type cutter 72.

[0071] See the appendix Figure 25 As shown, the cutting-type cutter 72 includes a first cutter body 721. A card slot 722 extending to the middle is provided on the upper part of the first cutter body. The inner side wall of the card slot 722 is pressed into a knife-edge shape for cutting the cable to contact the inner conductor of the cable to achieve data transmission. The tail of the first cutter body 721 adopts a fisheye-shaped through hole 723. Therefore, when connecting with the second PCB circuit board 32, no soldering process is required, which not only reduces the production difficulty and cost, but also fundamentally solves the poor contact caused by problems such as solder leakage and false soldering, and improves the service life. Limiting points 724 are provided on both sides of the first cutter body 721 for providing a hard limit to the cutting-type cutter 72 when it is inserted.

[0072] See the appendix Figure 26 As shown, a card slot 421 corresponding to the second wire clamping device 52 is provided on the second terminal block 42. In this embodiment, the number of two rows of pins 222a and 222b is eight, and the number of card slots 421 is also eight, and every two are distributed at the four corners of the terminal block 42.

[0073] See the appendix Figure 27a 、 27b As shown, the second wire clamping device 52 includes a second wire-striking cover body 521. The second wire-striking cover body 521 has a hole 522 extending from the back to the front for passing through the cable. A crimping surface 524 is provided on the front of the wire-striking cover body 521. A plurality of wire clamping components communicating with the hole 522 are provided on the back of the wire-striking cover body 521, and the plurality of wire clamping components are evenly distributed on the wire-striking cover body 521 along the circumferential direction of the hole 522.

[0074] Specifically, each of the wire clamping components includes a first side wall 5231 and a second side wall 5232.

At the top of the second side wall 5232, there are two open grooves 5234 (the number is not limited to two, but two is the best). The semi-closed grooves 5233 and the open grooves 5234 are arranged corresponding to each other. The first side wall 5231, the second side wall 5232 and the wire punching cover body 521 form a tangent groove 5235. Between two adjacent first side walls 5231 and between two adjacent second side walls 5232, they are connected by a separation part 5236 at the same time. As shown in the figure, there are four wire clamping components, which are evenly distributed at the four corners on the back of the wire punching cover body 521. Each of the wire clamping components includes a first side wall 5231 and a second side wall 5232. At the top of each first side wall 5231, there are two semi-closed grooves 5233. At the top of each second side wall 5232, there are two open grooves 5234. The corresponding semi-closed grooves 5233 and open grooves 5234 can clamp the cable more firmly. Every two semi-closed grooves 5233 are inserted into the corresponding cable group. By clamping the cable with the above semi-closed grooves 5233, the signal crosstalk between the cable groups can be effectively blocked, and the signal transmission efficiency is enhanced. The separation part 5236 is in a trapezoid shape surrounded by four connecting plates, which can separate the cable groups on two adjacent wire clamping components while strengthening the strength between the side walls, reducing signal crosstalk. There is a limit card slot 5237 on the separation part 5236. The crimping inclined surface 525 provided on the front of the wire punching cover body 521 can increase the connection tightness between the cable group and the electrical plug connector, reduce signal attenuation, and ensure the signal transmission quality.
