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

[0063] It should be noted that similar reference numerals denote similar items in the following figures. Therefore, once an item is defined in one figure, it will not be further defined or explained in the subsequent figures. In order to more clearly illustrate the structure, the proportions of the components in the figures are not true to scale.

These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on the present invention. The terms "first" and "second" are used solely to facilitate understanding and have no other directional meanings, and should not be construed as limitations on the present invention.

[0065] like Figures 1-3 As shown, this embodiment provides an anti-dropout plug-in wiring assembly, including two terminals that dock with each other: a first terminal 100 and a second terminal 200. Both terminals include a housing 1, a conductive sheet 2, a pressure handle 3, and a disc-shaped metal spring 4. Each housing 1 includes a body 11 and a docking body 12, which both protect the internal conductive sheet and provide mechanical positioning for docking. In other words, the first terminal 100 includes a first housing 1001, which includes a first body 111 and a first docking body 121. The second terminal 200 includes a second housing 2001, which includes a second body 112 and a second docking body 122. Each conductive sheet 2 includes a flat plate portion 21 disposed on the body and a plug-in portion 22 extending into the docking body. In other words, the first terminal 100 includes a first conductive sheet 1002, which includes a first flat plate portion 211 disposed on the first body 111 and a first plug-in portion 221 extending into the first docking body 121. The second terminal 200 includes a second conductive sheet 2002 . The second conductive sheet 2002 includes a second flat portion 212 disposed on the second body 112 and a second plug portion 222 extending into the second mating body 122 .

[0066] As shown in Figure 3 , the first terminal 100 includes a horizontal plate 221a with a protrusion 221b at the end. The second terminal 200 includes two bent clamping plates: a first clamping plate 222a and a second clamping plate 222b. The clamping plates are opposite and the bent part is close to form a resilient clamping opening 5. When the two pairs of connectors are connected, the horizontal plate 221a is inserted between the clamping plates and comes into contact with each other to achieve current continuity. The protrusion is clamped into the clamping opening and is "caught" by the resilient clamping opening 5 to form a anti-back lock to ensure that the first terminal 100 and the second terminal 200 will not be separated under vibration and pulling, and the plug-in force is moderate and can be repeatedly plugged in. The overall structure is compact, which supports on-site quick wiring and ensures high reliability after connection.

[0067] As shown in Figures 12-17 , the inner hole size of the first connector 121 is larger than the outer contour size of the second connector 122, and the second connector 122 is inserted into the first connector 121, thereby forming an opposite plug-in constraint relationship with the first plug-in part 221 and the second plug-in part 222, and further improving the physical stability of the plug-in. The second connector 122 and the first connector 121 are locked in position through the side buckle connection relationship, further improving the stability of the physical connection.

[0068] As shown in Figures 2-3 , in each terminal, the disc-shaped metal spring 4 is located in the body 11, and the pressing handle 3 is hinged to the body 11 to realize tool-free wiring.

[0069] Specifically, as shown in Figures 6-7 , 10-11, the disc-shaped 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 separated in the form of a finger, including a contact portion 41 on both sides and a wire clamping portion 42 in the middle. The contact portion 41 is bent downward, and the wire clamping portion 42 is raised upward. The pressing handle 3 includes two pressing feet 31 that cooperate with the contact portion 41. A channel is formed between the two pressing feet 31 for guiding the plug-in, and the width of the first flat plate part 211 or the second flat plate part 212 is less than the distance between the two pressing feet 31, thereby avoiding the interference of the pressing handle 3 operation with the guide. The disc-shaped metal spring 4, the pressing handle 3, the first conductive sheet 1002 or the second conductive sheet 2002 cooperate to realize the opening and closing of the wiring channel and also realize the compression and relaxation of the wire.

[0070] It can be understood that through the split-finger design, both the contact portion 41 and the wire clamping portion 42 become independent elastic bodies, and the stiffness is significantly reduced; the force required under the same deformation is smaller, and the operation of the pressing handle 3 is more labor-saving. The contact portion 41 bends downward to preposition the force point and enlarge the lever ratio. The wire clamping portion 42 is upwardly raised to form an angle with the flat plate part, and the angle direction is away from the direction of the guide channel.

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

[0072] As shown in Figures 16-17 , when the wire channel is inserted with the wire, the end of the wire clamping part 42 abuts against the wire, and the wire can be clamped by the wire clamping part 42 and the corresponding first flat plate part 211 or second flat plate part 212, preventing loosening and heating.

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

[0074] It should be noted that, as shown in Figure 3 , 6 , the free end of the downwardly curved abutting part 41 of the upper arm 4a is inclined from the end close to the wire insertion hole 101 to the end of the docking body from top to bottom, and the rear section of the abutting part 41 and the rear section of the upper arm 4a are located on the same inclined surface, which is inclined from the end close to the wire insertion hole 101 to the end of the docking body from bottom to top. The width of the pressing foot 31 gradually increases from the free end to the rear and then decreases.

[0075] As shown in Figure 3 , 7 , the lower surface of the pressing foot 31 includes a front inclined surface 311 inclined from the end close to the wire insertion hole 101 to the end of the docking body from bottom to top and a rear inclined surface 312 inclined from the end close to the wire insertion hole 101 to the end of the docking body from top to bottom, and the front inclined surface 311 and the rear inclined surface 312 are connected by a circular arc segment 313. The design of the inclined surface makes the pressing foot 31 generate an increasing downward pressure during sliding, achieving a "self-increasing force" effect, and the pressing handle 3 will not be stuck in the middle.

[0076] As shown in Figure 2 , 3 , 8, in the first terminal 100, the first flat plate part 211 and the horizontal plate 221a are offset by a distance in height and are connected by a connecting part 213. The first flat plate part 211, the horizontal plate 221a, and the connecting part 213 are all circularly arcuate. The offset design makes the wire inlet and the plug-in port not in the same plane, reducing the wire bending stress, and at the same time, it can buffer the influence of the docking force of the two terminals on the wire in the terminal. In addition, the offset design also improves the strength of the conductive sheet, avoiding its breakage. The circular arc transition eliminates sharp corners, avoiding stress concentration and sharp corner discharge, improving the service life and safety.

[0077] As Figure 2 , 3 , 8 shown, the first shell 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, and the connecting part 213 is blocked in the first body 111 by the longitudinal partition 7 to form a limit.

[0078] As Figure 3 , 8 shown, in the first terminal 100, the first flat plate part 211 is tightly attached to the upper wall of the inner cavity of the first body 111, the first flat plate part 211 is provided with a positioning clamping protrusion 8, the upper wall is provided with a positioning clamping hole 9, and the positioning clamping protrusion 8 and the positioning clamping hole 9 are clamped to limit the movement of the conductive sheet. The clamping structure limits the movement of the conductive sheet in front and back and left and right directions, and no additional screws are required during assembly, which simplifies the process and prevents poor contact caused by displacement of the conductive sheet due to vibration. Similarly, in the second terminal, the second conductive sheet 2002 also adopts the same positioning clamping protrusion 8 and positioning clamping hole 9 to realize the fixation with the second shell 2001.

[0079] As Figure 2 , 3 , 9 shown, in the second terminal 200, the front parts of the first clamping plate 222a and the second clamping plate 222b gradually move away from the elastic clamping opening 5 to form a fish mouth-shaped flared f, which plays a guiding role, and the horizontal plate 221a can be blindly inserted and aligned. The rear parts of the two clamping plates gradually expand outward and are connected with the mutually parallel transverse plates 223, and the two transverse plates are connected through the vertical plates 224. The transverse plate on the upper side is integrally connected in the same direction as the second flat plate part 212. The transverse plate + vertical plate forms a "U"-shaped reinforcing frame, which improves the elasticity and strength of the clamping plate and prevents the clamping force from decaying after repeated plugging and unplugging.

[0080] As Figure 8 , 9 , 12 shown, the ends of the first flat plate part 211 and the second flat plate part 212 are raised upward to form a first limiting part m, and the pressing handle 3 is provided with a second limiting part n protruding downward between the two pressing feet 31, and the first limiting part and the second limiting part are close to each other on the left and right sides to further improve the assembly stability of the conductive sheet and the shell.

[0081] As Figures 6-7 , 14-15 shown, the upper arm 4a of the disc-shaped metal elastic sheet 4 is provided with a positioning groove 10 on the rear side of the abutting part 41, the pressing handle 3 is rotated to press and hold the abutting part 41 by the pressing foot 31, and the front end of the pressing foot 31 enters the positioning groove 10 after the pressing handle 3 is pressed to realize the limiting. When the pressing handle 3 is pressed down, the front end of the pressing foot 31 falls into the groove to form a "click" limiting, which prevents the pressing handle 3 from rebounding, keeps the wiring channel continuously open, and facilitates two-handed operation or batch wiring. Preferably, the front end of the pressing foot 31 is in a circular arc shape.

[0082] AsFigures 3-5 As shown, the shell comprises a left and right butt joint first half shell 1a and second half shell 1b. The first half shell 1a is provided with a wire insertion hole 101, a pressing handle mounting position 102, a connection interface 103, and an insertion ear 104 provided with a clamping tongue 40. The second half shell 1b is provided with a connection body 105 inserted into the connection interface 103, a butt body 12, and a base body 107 located between the connection body 105 and the butt body, the base body 107 is provided with a clamping hole 70, the connection body 105 is inserted into the connection interface 103, the insertion ear 104 is inserted into the base body 107, and the clamping tongue 40 is clamped with the clamping hole 70. In this way, the conductive sheet 2 and the disc-shaped metal spring 4 inside the shell 1 are facilitated to be installed, the screwless quick assembly is realized, the production cost is reduced, and the shell sealing property is ensured. In addition, the first half shell can be made of transparent material, so that the wire insertion condition is more convenient to observe.

[0083] The anti-falling plug-in type wiring assembly is introduced, the principle and implementation mode of the present application are described by using specific examples, and the above examples are only used to help understand the present application and the core idea. It should be pointed out that for ordinary skilled in the art, without departing from the principle of the present application, the present application can be improved and modified, and these improvements and modifications also fall within the protection scope of the present application.
