[0062] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0063] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined or explained in subsequent figures. For clarity of the structure, the proportions of the components in the figures are not actual proportions.

[0064] In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Similarly, "first" and "second" are only for ease of understanding and have no other directional meaning, and cannot be considered as limitations on this utility model.

[0065] like Figure 1-3As shown, this embodiment provides an anti-dislodgement plug-in wiring assembly, including two mating terminals: a first terminal 100 and a second terminal 200. Each terminal includes a housing 1, a conductive piece 2, a pressure handle 3, and a disc-shaped metal spring 4. Each housing 1 includes a body 11 and a mating body 12, protecting the internal conductive piece and providing mechanical positioning for mating. Specifically, the first terminal 100 includes a first housing 1001, which includes a first body 111 and a first mating body 121. The second terminal 200 includes a second housing 2001, which includes a second body 112 and a second mating body 122. Each conductive piece 2 includes a flat plate portion 21 placed within the body and a insertion portion 22 extending into the mating body. Specifically, the first terminal 100 includes a first conductive piece 1002, which includes a first flat plate portion 211 placed within the first body 111 and a first insertion portion 221 extending into the first mating body 121. The second terminal 200 includes a second conductive sheet 2002, which includes a second flat plate portion 212 disposed on the second body 112 and a second insertion portion 222 extending into the second docking body 122.

[0066] like Figure 3 As shown, the first connector 221 of the first terminal 100 includes a horizontal plate 221a with a protrusion 221b at its end. The second connector 222 of the second terminal 200 consists of two bent clamping plates: a first clamping plate 222a and a second clamping plate 222b. The clamping plates are positioned opposite each other, with their bends abutting to form an elastic clamping opening 5. When the two terminals are joined, the horizontal plate 221a is inserted between the clamping plates, aiming to make contact with each other to achieve continuous current. The protrusion is engaged in the clamping opening and "bitten" by the elastic clamping opening 5, forming an anti-retrieval lock to ensure that the first terminal 100 and the second terminal 200 will not loosen or separate under vibration or pulling. At the same time, the insertion and extraction force is moderate, allowing for repeated insertion and extraction. The overall structure is compact, supporting both rapid field wiring and ensuring high reliability after connection.

[0067] like Figure 12-17 As shown, the inner diameter of the first mating body 121 is larger than the outer diameter of the second mating body 122. The second mating body 122 is inserted into the first mating body 121, thereby forming an opposite insertion constraint relationship with the first insertion portion 221 and the second insertion portion 222, thus improving the physical stability of the insertion. The second mating body 122 and the first mating body 121 are locked in position by a snap-fit ​​connection on the side, further improving the stability of the physical connection.

[0068] like Figure 2-3 As shown, in each terminal, the disc-shaped metal spring 4 is located inside the body 11, and the pressure handle 3 is hinged to the body 11 to achieve tool-free wiring.

[0069] Specifically, such as Figure 6-7As shown in Figures 10-11, the disc-type metal spring 4 includes an upper arm 4a and a lower arm 4b. The lower arm 4b is fixed to the bottom of the body 11. The free end of the upper arm 4a is finger-shaped and includes a contact portion 41 on both sides and a wire clamping portion 42 in the middle. The contact portion 41 is bent downwards, and the wire clamping portion 42 is curved upwards. The pressure handle 3 includes two pressure feet 31 that cooperate with the contact portion 41. A channel for guiding insertion and removal is formed between the two pressure feet 31. The width of the first flat plate portion 211 or the second flat plate portion 212 is smaller than the distance between the two pressure feet 31, thereby avoiding interference of the pressure handle 3 operation with the guide. The disc-type metal spring 4, the pressure handle 3, and the first conductive plate 1002 or the second conductive plate 2002 cooperate to realize the opening and closing of the wiring channel, as well as the clamping and loosening of the wire.

[0070] It can be understood that, through the finger-separated design, the two contact parts 41 and the clamping part 42 become independent elastic bodies, significantly reducing stiffness; less force is required for the same amount of deformation, making the operation of the handle 3 easier. The downward bending of the contact part 41 places the force point forward, increasing the leverage ratio. The clamping part 42 curves upward, forming an angle with the flat plate, and the direction of this angle is opposite to the guide direction.

[0071] like Figure 12-13 As shown, when the pressure handle 3 is in the first state, the end of the clamping part 42 abuts against the corresponding first flat plate part 211 or second flat plate part 212, and the wiring channel is closed.

[0072] like Figure 16-17 As shown, when the wire is inserted into the wiring channel, the end of the clamping part 42 presses tightly against the wire, and the wire can be clamped by the clamping part 42 and the corresponding first plate part 211 or second plate part 212 to prevent loosening and overheating.

[0073] like Figure 14-15 As shown, when the pressure handle 3 is in the second state, the pressure foot 31 presses against the contact part 41, the upper arm 4a deforms downward, and the end of the wire clamping part 42 moves away from the corresponding first flat plate part 211 or second flat plate part 212, opening the wiring channel. The wire can be quickly inserted or pulled out from the area between the two pressure feet 31, improving construction efficiency.

[0074] It should be noted that, such as Figure 3 , 6 As shown, the downward-curved free end of the contact portion 41 of the upper arm 4a slopes downwards from the end near the insertion hole 101 toward the end of the mating body. The rear section of the contact portion 41 and the rear section of the upper arm 4a are located on the same inclined plane, which slopes upwards from the end near the insertion hole 101 toward the end of the mating body. The width of the presser foot 31 gradually increases and then decreases from the free end toward the rear.

[0075] like Figure 3 , 7As shown, the lower surface of the presser foot 31 includes a front inclined surface 311 that slopes upward from the end near the insertion hole 101 toward the end of the mating body, and a rear inclined surface 312 that slopes downward from the end near the insertion hole 101 toward the end of the mating body. The front inclined surface 311 and the rear inclined surface 312 are connected by an arc segment 313. The "inclined surface" design causes the presser foot 31 to generate gradually increasing downward pressure during sliding, achieving a "self-amplifying force" effect, and the press handle 3 will not get stuck in the middle.

[0076] like Figure 2 , 3 As shown in Figure 8, within the first terminal 100, the first flat plate portion 211 and the horizontal plate 221a are offset in height by a distance and connected by a connecting portion 213. Both the first flat plate portion 211 and the horizontal plate 221a have rounded transitions with the connecting portion 213. This offset design ensures that the wire inlet and the connector are not on the same plane, reducing wire bending stress and buffering the impact of the mating force between the two terminals on the wires inside the terminal. Furthermore, the offset design increases the strength of the conductive sheet, preventing breakage. The rounded transition eliminates sharp angles, avoiding stress concentration and sharp-angle discharge, thus improving lifespan and safety.

[0077] like Figure 2 , 3 As shown in Figure 8, the first housing 1001 is provided with a longitudinal partition 7 to isolate the first body 111 and the first docking body 121. The longitudinal partition 7 is provided with a through hole for the horizontal plate 221a to pass through. The connecting part 213 is blocked by the longitudinal partition 7 within the first body 111 to form a limit.

[0078] like Figure 3 , 8 As shown, within the first terminal 100, the first flat plate portion 211 is tightly fitted against the upper wall of the inner cavity of the first body 111. The first flat plate portion 211 is provided with a positioning protrusion 8, and the upper wall is provided with a positioning hole 9. The positioning protrusion 8 and the positioning hole 9 engage to restrict the movement of the conductive sheet. This snap-fit ​​structure restricts the forward, backward, left, and right movement of the conductive sheet, eliminating the need for additional screws during assembly, simplifying the process, and preventing poor contact caused by the conductive sheet shifting due to vibration. Similarly, within the second terminal, the second conductive sheet 2002 also uses the same positioning protrusion 8 and positioning hole 9 to fix it to the second housing 2001.

[0079] like Figure 2 , 3As shown in Figure 9, within the second terminal 200, the front portions of the first clamping plate 222a and the second clamping plate 222b gradually move forward from their elastic clamping openings 5 ​​to form a fish-mouth-shaped flare f, serving as a guide, allowing the horizontal plate 221a to be blindly inserted and aligned. The rear portions of the two clamping plates gradually slope outward and connect with the parallel horizontal plates 223, which are connected by a vertical plate 224. The upper horizontal plate is integrally connected to the second flat plate portion 212 in the same direction. The horizontal plates and vertical plates form a "U"-shaped reinforcing frame, improving the elasticity and strength of the clamping plates and preventing the clamping force from weakening after repeated insertion and removal.

[0080] like Figure 8 , 9 As shown in Figures 1 and 12, the ends of the first flat plate portion 211 and the second flat plate portion 212 curve upward to form a first limiting portion m. The pressure handle 3 has a downward protruding second limiting portion n between the two pressure feet 31. The first limiting portion and the second limiting portion are close to each other to further improve the assembly stability of the conductive sheet and the housing.

[0081] like Figure 6-7 As shown in Figures 14-15, the upper arm 4a of the disc-type metal spring 4 is provided with positioning grooves 10 on the rear side of the contact portion 41. The pressure handle 3 rotates to cause the pressure foot 31 to press against the contact portion 41 until the front end of the pressure foot 31 enters the positioning groove 10 and is thus limited. When the pressure handle 3 is pressed down, the front end of the pressure foot 31 falls into the groove to form a "click" limit, preventing the pressure handle 3 from springing back and keeping the wiring channel continuously open, which is convenient for two-handed operation or batch wiring. Preferably, the front end of the pressure foot 31 is arc-shaped.

[0082] like Figure 3-5 As shown, the housing includes a first half-shell 1a and a second half-shell 1b joined together. The first half-shell 1a has a wire insertion hole 101, a pressure handle mounting position 102, a connection port 103, and a plug-in ear 104, with a latch 40 on the plug-in ear 104. The second half-shell 1b has a connector 105 inserted into the connection port 103, a docking body 12, and a base 107 located between the connector 105 and the docking body. The base 107 has a locking hole 70. The connector 105 is inserted into the connection port 103, the plug-in ear 104 is inserted into the base 107, and the latch 40 engages with the locking hole 70. This design facilitates the installation of the conductive sheet 2 and the disc-shaped metal spring 4 inside the housing 1, enabling screwless rapid assembly, reducing production costs, and ensuring the housing's airtightness. Furthermore, the first half-shell can be made of a transparent material, making it easier to observe the wire connection status.
