In this utility model, the directional terms "front" refer to the head direction of the insulating socket shell and the insulating plug shell, and "rear" refers to the tail direction of the insulating socket shell and the insulating plug shell. These two directions are consistent with the actual orientation of the product. Furthermore, directions such as "top," "bottom," "left," and "right" are for reference only in the accompanying drawings and do not represent the actual orientation of the product.

[0019] like Figure 1-3 The protective-free self-locking mating connector shown includes a socket 10 and a plug 20. The socket 10 includes an insulating socket shell 11, and the plug includes an insulating plug shell 21. Both the insulating socket shell 11 and the insulating plug shell 21 are square shells that extend from head to tail. The insulating plug shell 21 is inserted into the mating slots on the front of the insulating socket shell 11 on the corresponding sides of its head through mating tabs. The insulating plug shell 21 is locked to the insulating socket shell 11 on the other two sides of its head through first locking buckles and first locking holes on the other two sides of its head, so as to lock the insulating plug shell 21 and the insulating socket shell 11 together.

[0020] like Figure 2As shown, a first longitudinal partition 11.1 is provided in the rear inner part of the insulating socket housing 11, which divides the rear inner part of the insulating socket housing 11 into two insertion chambers, left and right; as Figure 2-6 As shown, a first insulating plate 12 is erected on the inner front part of the insulating socket housing 11. The first insulating plate 12 is a rectangular plate and its four sides respectively contact the four inner walls of the insulating socket housing 11. The first plate 12 is attached to the first longitudinal plate 11.1 and is locked to the second locking holes on the corresponding two sides of the insulating socket housing 11 by the second latches on the rear plate side, thereby fixing it inside the insulating socket housing 11.

[0021] like Figure 2-6 As shown, three first horizontal slots 12.1 are provided on the first insulating plate 12, centered on the left and right and vertically spaced apart. Each first horizontal slot 12.1 contains a conductive female component 13. The conductive female component 13 is a flat block and includes a first conductive clip 13.1 located at its front and opening forward and a second conductive clip 13.2 located at its rear and opening backward. The three conductive female components 13 are respectively inserted and fixed into the three first horizontal slots 12.1 from the rear through their respective first conductive clips 13.1, with their respective first conductive clips 13.1 protruding from the front of the first insulating plate 12.

[0022] like Figure 3-6 As shown, two first horizontal partitions 12.2 are provided on the front plate surface of the first insulating plate 12. The two first horizontal partitions 12.2 are arranged alternately with the three first horizontal slots 12.1 to separate the three first conductive clips 13.1 from each other. This can prevent the three first conductive clips 13.1 from touching each other.

[0023] like Figure 4 and 6 As shown, each conductive mother component 13 has two second conductive clips 13.2 spaced laterally at its rear. The second conductive clips 13.2 on the left side of the three conductive mother components 13 are located on the same vertical line to form a group, and the second conductive clips 13.2 on the right side of the three conductive mother components 13 are located on another vertical line to form another group. Each group of second conductive clips 13.2 is equipped with a wiring mechanism 30.

[0024] like Figure 2-6As shown in Figure 8, the wiring mechanism 30 includes a first insulating base 31, a V-shaped conductive plate 32, and a second insulating base 33. The first insulating base 31 is inserted from the rear opening into the insertion cavity behind each set of second conductive clips 13.2. The first insulating base 31 includes a rear-opening base body 31.1 and locking plates 31.2 symmetrically arranged on the left and right sides of the base body 31.1. The base body 31.1 has three rear-opening partitions 31.11 spaced vertically inside. Each partition 31.11 has clamping holes 31.12 on its left and right sides that connect to the outside. The V-shaped conductive plate 32 includes three... The first insulating base 32 is located in one of three compartments 31.11, with each V-shaped conductive sheet 32 ​​having its opening facing rearward within its respective compartment 31.11. The second insulating base 33 is located between two locking plates 31.2, with its front end inserted into the rear opening of the first insulating base 31, and its rear end locked to the first insulating base 31 by the two locking plates 31.2. Inside, there are three straight wire guide holes 33.1 that are spaced vertically and are connected front to back. The three wire guide holes 33.1 are respectively connected to the three compartments 31.11 and are respectively aligned with the opening ends of the three V-shaped conductive sheets 32.

[0025] like Figure 2-6 As shown in Figure 8, the connection method between each group of second conductive clips 13.2 and the corresponding wiring mechanism 30 is as follows: the two arms of the three second conductive clips 13.2 are inserted into the three cavities 31.11 along the clamping holes 31.12 on both sides of the first insulating seat 31, so as to clamp and connect the three V-shaped conductive plates 32 respectively, and clamp and close the openings of the three V-shaped conductive plates 32.

[0026] like Figure 2-5 As shown in Figure 8, the wiring mechanism 30 also includes two insulating push-pull tabs 34, which are respectively disposed on the top and bottom sides of the second insulating base 33. The insulating push-pull tabs 34 are U-shaped, and their two U-arms serve as connecting arms 34.1 and push-pull arms 34.2, respectively. Their U-ports are movably sleeved onto the rear end of the insulating socket housing 11 from the rear. The connecting arm 34.1 is located inside the insulating socket housing 11 and slides back and forth on the outer wall of the second insulating base 33 through the groove 34.11 provided on its outer surface. The connecting arm 34.1 is also movably connected to the second insulating base 33 through the rotating shafts 34.12 correspondingly provided on both sides of the groove 34.11. The push-pull arm 34.2 of the flange 33 is slidably disposed in the front-to-back sliding groove provided on the outer wall of the insulating socket housing 11 and is locked to the third locking hole provided at the bottom of the sliding groove by the third latch provided on its inner surface, thereby fixing the insulating push-pull tab 34 to the insulating socket housing 11, and then locking the first insulating seat 31 in the plug cavity. After the push-pull arm 34.2 is unlocked, the first insulating seat 31 can be driven to move back and forth in the insulating socket housing 11 through the second insulating seat 33, so as to drive the opening of the three V-shaped conductive plates 32 inside the first insulating seat 31 to open or clamp and close.

[0027] like Figure 2As shown, a second longitudinal partition 21.1 is provided in the rear inner part of the insulating plug housing 21, which divides the rear inner part of the insulating plug housing 21 into two insertion cavities, left and right; as Figure 2-6 As shown, a second insulating plate 22 is erected on the inner front part of the insulating plug housing 21. The second insulating plate 22 is a rectangular plate and its four sides respectively contact the four inner walls of the insulating plug housing 21. The second insulating plate 22 is attached to the second longitudinal partition 21.1 and is locked to the fourth locking holes on the corresponding two sides of the insulating plug housing 21 through the fourth locking buckles on its rear plate, thereby fixing it inside the insulating plug housing 21 and being arranged opposite to the plate surface of the first insulating plate 12.

[0028] like Figure 2-5 As shown in Figure 7, three second horizontal slots 22.1 are provided on the second insulating plate 22, centered horizontally and vertically spaced. The three second horizontal slots 22.1 correspond one-to-one with the three first horizontal slots 12.1. Each second horizontal slot 22.1 contains a conductive male component 23. The conductive male component 23 is a flat block and includes a male plug 23.1 at its front and a third conductive clip 23.2 at its rear with its opening facing backward. The three conductive male components 23 are respectively inserted and fixed into the three second horizontal slots 22.1 from the rear through their respective male plugs 23.1, with their respective male plugs 23.1 protruding from the front of the second insulating plate 22.

[0029] like Figure 2-5 As shown in Figure 7, the front surface of the second insulating plate 22 is provided with two second transverse partitions 22.2 corresponding to the first transverse partition 12.2. The two second transverse partitions 22.2 are arranged alternately with the three second transverse slots 22.1 to separate the three male plugs 23.1. The front ends of each pair of first transverse partitions 12.2 and second transverse partitions 22.2 are interlocked with each other through reverse stepped surfaces, thereby jointly separating the three pairs of first conductive clips 13.1 and male plugs 23.1 from each other.

[0030] like Figure 2-5 As shown in Figures 7-8, each conductive male component 23 has two third conductive clips 23.2 spaced laterally at its rear. The third conductive clips 23.2 on the left side of the three conductive male components 23 are all located on the same vertical line to form a group, and the third conductive clips 23.2 on the right side of the three conductive male components 23 are located on another vertical line to form another group. Each group of third conductive clips 23.2 is equipped with a wiring mechanism 30. The connection method between the third conductive clip 23.2 and the wiring mechanism 30 is the same as the connection method between the second conductive clip 13.2 and the wiring mechanism 30.

[0031] The wiring operation method is taken as an example with plug 20, such as... Figure 9 and 10As shown, the two insulating push-pull tabs 34 of the same wiring mechanism 30 are unlocked from the insulating plug housing 21. The two insulating push-pull tabs 34 are pushed backward by the push-pull arm 34.2. The two insulating push-pull tabs 34 drive the first insulating seat 31 to move backward through the second insulating seat 33. The first insulating seat 31 drives the three V-shaped conductive plates 32 inside it to disengage from the corresponding third conductive clips 23.2. The open ends of the three V-shaped conductive plates 32 are opened. The bare wire ends of the live wire, neutral wire and ground wire of the three-pole wire 40 are inserted into the clips of the three V-shaped conductive plates 32 through the three wire guide holes 33.1 on the second insulating seat 33, respectively. Then, the first insulating seat 31 is pushed back to reset. The three third conductive clips 23.2 re-clamp and connect the three V-shaped conductive plates 32. The open ends of the three V-shaped conductive plates 32 clamp the bare wire ends of the wire 40, thereby electrically connecting the wire 40 to the three conductive parts 23. The wiring operation method of socket 10 is the same as that of plug 20.
