[0002] A patent document with publication number CN207021625U discloses a junction box and a jumper junction box assembly. The junction box includes a box body with a cavity inside. A wiring hole is provided on the cavity wall surrounding the cavity. A connecting post is provided inside the cavity and closely attached to the inner wall of the cavity. It also includes a cover plate detachably connected to the box body. The edge of the cover plate has a notch corresponding to the position of the connecting post. At least one set of opposite sides of the box body are provided with jumper connectors. The jumper connectors are coaxially distributed with the wiring holes. The above-described junction box, based on the traditional junction box, adds a cover plate and jumper connectors, which not only prevents impurities from entering the junction box during construction, but also enables quick connection between multiple junction boxes when needed.

[0003] Currently, most junction boxes still have limitations in practical use. In existing technologies, the connection between the junction box and the terminal block mostly relies on screw tightening or simple plugging and unplugging, lacking components for quick snap-fit ​​fixing of the terminal block. Under environments such as vibration, the terminal block may easily loosen, resulting in problems such as poor contact and safety hazards, making it difficult to meet the requirements for efficient and reliable electrical connections.

[0004] Therefore, this utility model proposes a quick connector for lines to solve the above problems. Utility Model Content

The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0021] Example 1: Please refer to Figures 1 to 2 A quick-connect connector and an easy-to-assemble junction box are provided, including a terminal 1, a connector 2, and a fixing rod 3. The terminal 1 is fixedly mounted on the junction box 4, and the fixing rod 3 is provided at the end of the terminal 1. The connector 2 is connected to the terminal 1. The junction box 4 is provided with a positioning component 5, a fixing component 6, and an elastic component 7. The positioning component 5 is fixedly mounted on both sides of the junction box 4, the fixing component 6 is fixedly mounted on the positioning component 5, and the elastic component 7 is mounted on the fixing component 6.

[0022] The snap-fit ​​protrusion 501 in the positioning component 5 is fixedly installed inside the fixing rod 3, and snap-fit ​​holes 502 are evenly arranged on the snap-fit ​​protrusion 501.

[0023] In use, the terminal 1 is fixed on the junction box 4, and the snap-fit ​​protrusion 501 is located inside the fixing rod 3. When connecting the line, hold the connector 2 close to the terminal 1. The positioning protrusion 503 at the end of the connector 2 will automatically align with the snap-fit ​​hole 502 on the snap-fit ​​protrusion 501. Push the connector 2 forward and the positioning protrusion 503 snaps into the snap-fit ​​hole 502 to complete the initial positioning.

[0024] Example 2: Based on Example 1, please refer to... Figures 2 to 3 The positioning component 5 has a positioning protrusion 503 fitted into the snap-fit ​​hole 502, and the positioning protrusion 503 is evenly distributed at the end of the connector 2.

[0025] The first fixing cover 601 in the fixing component 6 has a first fixing groove 602 inside, a handle 603 is provided at the top of the first fixing cover 601, and a first fixing piece 604 is provided at the end of the first fixing cover 601.

[0026] In use, after the positioning protrusion 503 is inserted into the snap-fit ​​hole 502, pull open the first fixing cover 601 and cover the connection part with the handle 603, so that the first fixing groove 602 is aligned with the connection point of the connector 2 and the terminal 1. At this time, the first fixing piece 604 is on one side. Snap the second fixing cover 605 from bottom to top and splice it with the first fixing cover 601. The snap-fit ​​fixing groove 606 covers the connection part. The first fixing piece 604 and the second fixing piece 607 correspond to each other, preparing for subsequent fixing.

[0027] Example 3: Based on Example 2, please refer to... Figures 3 to 4 The first fixing cover 601 in the fixing component 6 is provided with a second fixing cover 605 at its bottom end. The first fixing cover 601 and the second fixing cover 604 are provided with snap-fit ​​fixing grooves 606. The second fixing cover 605 is provided with a second fixing piece 607 at its end. The second fixing piece 607 is provided with fixing holes 608.

[0028] One end of the spring 701 in the elastic component 7 is fixedly disposed at the bottom end of the first fixing plate 604, and the other end of the spring 701 is fixedly disposed inside the fixing hole 608. A positioning pin 702 is sleeved inside the spring 701, and the positioning pin 702 is fixedly disposed at the bottom end of the first fixing cover 601.

[0029] In use, when the first fixing cover 601 and the second fixing cover 605 are pulled open, the spring 701 is in a stretched state and is fitted onto the snap-fit ​​protrusion 501 and the connector 2. Then, the handle 603 is released, at which point the spring 701 retracts, and the positioning pin 702 passes through the spring 701 and is fixed at the bottom of the first fixing cover 601. The positioning pin 702 is firmly inserted into the fixing hole 608. The elastic force of the spring 701 makes the first fixing cover 601 and the second fixing cover 605 fit tightly together, firmly fixing the connector 2 and the terminal 1. Even in a vibrating environment, the connection can be kept stable by the elastic force of the spring 701. When disassembling, it is only necessary to overcome the elastic force of the spring 701 to separate the fixing cover.
