Description

Technical Field

[0001] This utility model relates to the field of electronic equipment, and more specifically, to a junction box for electronic engineering. Background Technology

[0002] In the field of electronic engineering, junction boxes, as key components for circuit connection and distribution, directly affect the stability and safety of the entire electronic system. With the rapid development of electronic technology, junction boxes must not only meet basic electrical connection functions but also possess good protection, ease of use, and flexibility to adapt to increasingly complex and varied electronic devices and application scenarios. However, traditional junction box designs often have many shortcomings, such as chaotic cable management, insufficient protection at connection points, and difficulties in installation and maintenance. These problems not only affect the overall performance of the electronic system but also increase operation and maintenance costs and potential safety hazards.

[0003] In terms of cable management, traditional junction boxes have limited internal space and lack effective cable fixing and guiding mechanisms, resulting in cables becoming tangled and messy inside the box. This not only affects aesthetics but also increases the risk of cable damage and electrical faults. In addition, the connection between the cable and the junction box body often lacks sufficient protection and is susceptible to environmental factors such as external pressure, wear, or moisture, leading to loose connections or failures, which in turn affect the normal operation of the circuit.

[0004] Therefore, a junction box for electronic engineering is proposed to address the above problems. Utility Model Content

[0030] Example:

[0031] Please see Figure 1-5An electronic engineering junction box includes a junction box body 1, a connecting rod 11 slidably connected inside the junction box body 1, a protection mechanism 2 and a rotation limiting mechanism 3 at the end of the connecting rod 11. The protection mechanism 2 is used to protect the connection between the cable and the junction box body 1; the rotation limiting mechanism 3 is used to allow the cable to be inserted into the junction box body 1. In this design, the protection mechanism 2 is slidably connected to the junction box body 1 through the connecting rod 11, and the friction between the outer wall of the connecting rod 11 and the junction box body 1 is relatively large.

[0032] The protection mechanism 2 includes a fixing plate 21, which is fixedly connected to the end of the connecting rod 11 away from the junction box body 1. A sliding block 23 is slidably connected to the top surface of the fixing plate 21. A mounting groove 26 is provided in the middle of the bottom end of the sliding block 23. A first spring 24 is fixedly connected inside the mounting groove 26. In this solution, the top end of the fixing plate 21 is provided with a sliding groove corresponding to the bottom end of the sliding block 23, so the sliding block 23 can slide above the fixing plate 21. The first spring 24 is fixedly connected inside the mounting groove 26.

[0033] A limiting block 25 is fixedly connected to the end of spring 24. A limiting groove 22 is formed on the top surface of the fixing plate 21. The limiting block 25 is engaged inside the limiting groove 22. The diameter of the limiting block 25 is smaller than the diameter of the limiting groove 22. A wiring groove 27 is formed on the outer wall of the sliding block 23. In this design, rounded corners are formed at the end of the limiting block 25 away from the sliding block 23 and at the opening of the limiting groove 22. The radius of the rounded corner at the end of the limiting block 25 away from the sliding block 23 is larger than the radius of the rounded corner at the opening of the limiting groove 22. When the sliding block 23 slides above the fixing plate 21, the limiting block 25 engages with the limiting plate 24. Inside the limiting groove 22, when the sliding block 23 slides, the edge of the limiting groove 22 will squeeze the limiting block 25. After the limiting block 25 is squeezed, the first spring 24 will undergo elastic deformation and compress and store a certain amount of elastic potential energy. When the limiting block 25 is completely separated from the inside of the limiting groove 22, the surface of the limiting block 25 will be in contact with the surface of the fixing plate 21. When the limiting block 25 slides to the top of the next limiting groove 22, the first spring 24, which is in an elastic contraction state, rebounds and pushes the limiting block 25 into the inside of the limiting groove 22. At this time, the movement of the sliding block 23 is limited.

[0034] The rotation limiting mechanism 3 includes a cover plate 31 and a second spring 35. The cover plate 31 and the fixed plate 21 are rotatably connected. A ratchet 32 ​​is fixedly connected to the lower part of the cover plate 31. The second spring 35 is rotatably connected to the lower part of the fixed plate 21. In this scheme, when the cover plate 31 rotates counterclockwise, it will drive the ratchet 32 ​​to rotate synchronously.

[0035] A latching block 33 is engaged with the outer wall of the ratchet 32. The lower part of the latching block 33 is rotatably connected to the upper part of the fixing plate 21. A handle 34 is fixedly connected to the outside of the latching block 33. In this design, when the cover plate 31 rotates counterclockwise, the outer wall of the ratchet 32 ​​will continuously press the latching block 33, and the end of the latching block 33 will be engaged with the ratchet 32. When the cover plate 31 is rotated to the required angle, the user can insert the cable through the wiring slot 27 and the junction box body 1. After the cable and the junction box body 1 are inserted, the user can push the handle 34 down to cause the second spring 35 to elastically deform and contract, and release the engagement between the latching block 33 and the ratchet 32. Then, the user can rotate the cover plate 31 clockwise, and after the bottom end of the cover plate 31 is attached to the top of the sliding block 23, the user can release the handle 34, so that the end of the latching block 33 is re-engaged on the outer wall of the ratchet 32.

[0036] The top of the second spring 35 is rotatably connected to the outside of the snap-fit ​​block 33. In this scheme, the snap-fit ​​block 33 can be supported by the second spring 35 through the rotatable connection between the second spring 35 and the snap-fit ​​block 33, so that the end of the snap-fit ​​block 33 is snapped into the outer wall of the ratchet 32.

[0037] Working principle: Before use, the user should check the device for damage. If the device is undamaged, and the user needs to connect the cable to the junction box body 1, the user can first rotate the cover plate 31 counterclockwise. As the cover plate 31 rotates counterclockwise, the outer wall of the ratchet 32 ​​will continuously press against the locking block 33, causing the end of the locking block 33 to engage with the ratchet 32. Once the cover plate 31 is rotated to the desired angle, the user can insert the cable through the wiring slot 27 into the junction box body 1. After the cable and junction box body 1 are connected, the user should pull the handle 34 downwards to allow the two... Spring 35 undergoes elastic deformation and contraction, releasing the engagement between latching block 33 and ratchet 32. The user then rotates cover plate 31 clockwise, bringing its bottom end to the top of sliding block 23, and releases handle 34, causing the end of latching block 33 to re-engage with the outer wall of ratchet 32. The user then slides fixing plate 21, causing connecting rod 11 to slide inside junction box body 1. After the end of fixing plate 21 closest to junction box body 1 is aligned with one side of junction box body 1, sliding block 23 and cover plate 31 can protect the connection between cable and junction box body 1.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
