[0062] The main body of the rectangular busbar 2 is coated with an insulating layer 7. A sleeve 8 is arranged between the female end plastic shell 1 and the insulating layer 7.

[0063] A specific embodiment is described below:

[0064] The utility model provides a self-locking quick-plug structure including a rectangular busbar, which includes a female end plastic shell 1, a rectangular busbar 2, a copper gasket 3, a female end buckle 4, a core rod 5, a female end cover plate 6, an insulating layer 7, a sleeve 8, and a copper sleeve 9.

[0065] like Figure 7and Figure 8 As shown, the female end plastic shell 1 is made of insulating engineering plastic with excellent strength and toughness, including a vertical wall 1.1, a slide rail 1.2, a side notch 1.3, a slide rail notch 1.4, a hollow cylinder 1.5, a bottom chamfer 1.6 and a bottom plate 1.7. Among them, the vertical wall 1.1, the bottom plate 1.7 and the female end cover plate 6 cooperate to form a cavity, isolating the conductive parts from the outside to form electrical insulation. The slide rail 1.2 is used to assemble with the corresponding features of the female end cover plate 6, so that the female end cover plate 6 can slide in the female end plastic shell 1 without falling off. The side notch 1.3 is used to insert and remove the female end buckle 4. The slide rail notch 1.4 is used for limiting and locking. When the female end cover plate 6 is pushed into place along the slide rail 1.2, the slide rail notch 1.4 locks the female end cover plate 6. The hollow cylinder 1.5 is used to install and fix the copper sleeve 9. The bottom chamfer 1.6 is used to correct the misaligned core rod 5.

[0066] like Fig.15 and Fig.16 The figure shows the structure of the female end cover plate 6. The female end cover plate 6 is made of insulating engineering plastic with excellent strength and toughness, and includes a side convex strip 6.1, a side oblique protrusion 6.2, and an internal circular groove 6.3. When in use, the side convex strip 6.1 is pushed into the slide rail 1.2 of the female end plastic shell 1. The side convex strip 6.1 can slide along the slide rail 1.2. When pushed into place, the side oblique protrusion 6.2 is matched with the slide rail notch 1.4 of the female end plastic shell 1, so that the side oblique protrusion 6.2 is stuck in the slide rail notch 1.4, thereby locking the female end cover plate 6. The internal circular groove 6.3 is used to place the top end of the core rod 5 to limit the position of the core rod 5 pushed upward.

[0067] like Fig. 9 The figure shows the structure of the rectangular busbar 2. The rectangular busbar 2 is composed of multiple layers of copper sheets with good conductivity, including a busbar body 2.1, a first circular hole 2.2, and a second circular hole 2.3. The first circular hole 2.2 is provided at one end of the busbar body 2.1, and the second circular hole 2.3 is provided at the other end. When in use, the first circular hole 2.2 is used to be coaxial with the through hole 1.8 in the female plastic shell 1, and is fixed with the copper sleeve 9, so that the quick plug is connected with both ends to form a closed loop, and the second circular hole 2.3 is used to be fixed with the external connector.

[0068] like Fig.10 As shown, it is a structural diagram of the copper gasket 3. The copper gasket 3 is made of a copper busbar with good conductive performance. When in use, the copper gasket 3 is first placed on the bottom plate 1.7 of the female plastic shell 1, so that the copper gasket 3 is concentric with the hollow cylinder 1.5, and then the rectangular busbar 2 is placed on the copper gasket 3, and the first circular hole 2.2 of the rectangular busbar 2 is aligned with the circular hole of the copper gasket 3, and then the copper sleeve 9 is inserted into the first circular hole 2.2 of the rectangular busbar 2. Among them, the copper gasket 3 has the rectangular busbar 2 above, the bottom plate 1.7 of the female plastic shell 1 below, and the copper sleeve 9 inside, which ensures that the copper sleeve 9 and the rectangular busbar 2 are tightly matched.

[0069] like Fig.19 and Fig. 20 As shown, the copper sleeve 9 is made of a copper rod with good conductivity, and includes a top boss 9.1 and a middle knurling 9.2, wherein the top boss 9.1 is used to press the rectangular busbar 2 and the copper gasket 3 through which the copper sleeve 9 passes during installation to prevent them from falling off, and the middle knurling 9.2 can facilitate the copper sleeve 9 to pass into the round holes of the rectangular busbar 2 and the copper gasket 3. The copper sleeve 9 as a whole serves to connect the core rod 5 and the rectangular busbar 2 to form a loop.

[0070] like Fig.13 and Fig.14 As shown, the core rod 5 is made of a copper rod with good conductivity, including a bottom boss 5.1 and a top groove 5.2. When the core rod 5 is inserted into the hollow cylinder 1.5 of the female plastic shell 1 from bottom to top, the bottom boss 5.1 will contact the bottom of the hollow cylinder 1.5 to prevent over-insertion, and the top groove 5.2 cooperates with the corresponding features of the female buckle 4 to lock the insertion position of the core rod 5.

[0071] like Fig.11 and Fig.12 As shown, it is a structural diagram of the female end buckle 4, combined with Fig. 22 The female end buckle 4 is made of insulating engineering plastic with excellent strength and toughness, and includes a push handle 4.1, a smooth round hole 4.2, a depression in the hole 4.3, and a side round groove 4.4. Fig. 22 As shown, the female end buckle 4 can be pushed in the left and right directions. When in use, the self-locking quick-insert structure is assembled as follows: a copper gasket 3 is placed above the through hole 1.8 of the bottom plate 1.7 of the female end plastic shell 1, a rectangular busbar 2 is placed above the copper gasket 3, a copper sleeve 9 is inserted from top to bottom into the first circular hole 2.2 of the rectangular busbar 2 and the copper gasket 3, the female end buckle 4 is assembled above the first circular hole 2.2 of the rectangular busbar 2 and the copper sleeve 9, and then the female end cover plate 6 is assembled;

[0072] Finally, assemble the mandrel 5. The assembly method of the mandrel 5 is as follows: Fig.21 , Fig.21To lock the connector, first push the push handle 4.1 to the right to move the female end buckle 4 to the right in the female end plastic shell 1. When pushed into place, the smooth round hole 4.2 of the female end buckle 4 is aligned with the first round hole 2.2 of the rectangular busbar 2. At this time, the mandrel 5 is inserted from bottom to top, and the top of the mandrel 5 can pass through the smooth round hole 4.2. At this time, release the push handle 4.1, and the compressed spring in the side circular groove 4.4 stretches to push the female end buckle 4 to the left. At this time, the depression 4.3 in the hole will move to the left and cooperate with the top groove 5.2 of the mandrel 5, so that the two are stuck, and the mandrel 5 cannot be pulled out. At the same time, the female end buckle 4 cannot be pushed out by the spring, which plays a role in positioning and locking the mandrel 5. When the mandrel 5 needs to be pulled out freely, it is only necessary to push the female end buckle 4 to move the female end buckle 4 to the right, so that the depression 4.3 in the hole is separated from the top groove 5.2 of the mandrel 5, and the mandrel 5 can be pulled out freely downward. Therefore, when the self-locking quick-insertion structure needs to be inspected, there is no need to disassemble the entire quick-insertion structure. The core rod 5 can be inspected by simply and quickly pulling it out.

[0073] like Fig.17 As shown, it is a structural diagram of the insulating layer 7. The insulating layer 7 is formed by extrusion of PVC particles, wrapping the main body of the rectangular busbar 2 to play a role in electrical insulation.

[0074] like Fig.18 , which is a structural diagram of a sleeve 8 , the sleeve 8 is made of plastic and is used to wrap the interface between the insulating layer 7 and the female end plastic shell 1 .

[0075] Practical use of this application structure:

[0076] First, place the copper gasket 3 on the bottom plate 1.7 of the female plastic shell 1, then place the first circular hole 2.2 of the rectangular busbar 2 on the copper gasket 3, pass the copper sleeve 9 from top to bottom through the first circular hole 2.2 and the copper gasket 3 and place it in the hollow cylinder 1.5 at the bottom of the female plastic shell 1, and insert the female buckle 4; combine the side convex strip 6.1 of the female cover plate 6 with the slide rail 1.2 of the female plastic shell 1 and push it in, and after the side oblique protrusion 6.2 is inserted into the slide rail notch 1.4, the female plastic shell 1 and the female cover plate 6 are fixed; then, push the female buckle 4, and push the core rod 5 from the bottom into the female plastic shell 1 after pushing it to the bottom, and release the female buckle 4 after pushing it to the bottom. The female buckle 4 is pushed outward under the action of the spring. At this time, the depression 4.3 in the hole on the female buckle 4 cooperates with the top groove 5.2 of the core rod 5 to fix the core rod 5, and the locking process is completed. When unlocking is required, the female end buckle 4 is pushed inward again, and the inner depression 4.3 of the hole on the female end buckle 4 is separated from the top groove 5.2 of the core rod 5, so that the core rod 5 can be pulled out.

[0077] Therefore, the self-locking quick-plug structure including a rectangular busbar provided by the utility model includes a female end plastic shell 1, a rectangular busbar 2, a copper gasket 3, a female end buckle 4, a core rod 5, a female end cover plate 6, an insulating layer 7, a sleeve 8, and a copper sleeve 9.

[0079] The rectangular busbar 2 is made of a copper strip with good conductivity. The surface of the copper strip is electroplated to reduce the contact resistance, and serves to connect the conductive parts such as the copper sleeve 9 in the plastic shell with the external conductive parts.

[0080] The copper gasket 3 is made of a copper busbar with good conductive properties. It is riveted together with the copper sleeve 9 when in use. After assembly, it contacts the bottom plate 1.7 of the female plastic shell 1, which can prevent the rectangular busbar 2 from shaking up and down, and at the same time increase the conductive contact area between the rectangular busbar 2 and the copper sleeve 9.

[0081] The female end buckle 4 is made of insulating engineering plastics with excellent strength and toughness, and cooperates with the female end cover plate 6 to form a self-locking design when in use. When the core rod 5 is inserted into place, the female end buckle 4 can lock it.

[0082] The core rod 5 is made of a copper rod with good conductivity and plays a role of conductive connection.

[0083] The female end cover plate 6 is made of insulating engineering plastics with excellent strength and toughness, and is assembled with the female end plastic shell 1 to form a cavity when in use, thereby playing a role of electrical insulation.

[0084] The insulating layer 7 is formed by extrusion of PVC particles and wraps the rectangular busbar 2 to provide electrical insulation.

[0085] The sleeve 8 is made of plastic and is used to wrap the interface between the insulating layer 7 and the female end plastic shell 1 .

[0086] The copper sleeve 9 is made of a copper rod with good electrical conductivity, and serves to connect the core rod 5 and the rectangular busbar 2 to form a loop.

[0087] The quick-insert structure is light, firm and reliable, and allows a certain installation error.

[0091] (3) It has a large fault tolerance. After the mandrel that is not fully aligned is inserted from the bottom, the bevel at the bottom of the plastic shell can be automatically corrected, allowing for a larger insertion error;

[0092] (4) This structure can make the conduction of large currents miniaturized, integrated, and modular, with good reliability while saving installation space.
