All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0025] The electrical terminal assembly with a dustproof protective cover disclosed in this utility model is mainly used in electrical terminal assembly scenarios.
[0026] Reference Figures 1 to 6 An electrical terminal assembly with a dustproof protective cover includes: a protective shell 1; a fixing plate 2 is fixedly connected at equal intervals inside the protective shell 1; a main terminal connector 3 is provided on one side of the fixing plate 2; a secondary terminal connector 4 is provided on one side of the main terminal connector 3; an internal slot 7 is provided inside the main terminal connector 3; an insert plate 8 is provided inside the secondary terminal connector 4; the outer side of the insert plate 8 is slidably connected to the inside of the slot 7; a main connecting wire 5 is fixedly connected to one side of the main terminal connector 3; a secondary connecting wire 6 is fixedly connected to one side of the secondary terminal connector 4; a cover plate 9 is fixedly connected to the top of the protective shell 1; a connecting component is provided between the tops of the main terminal connector 3 and the secondary terminal connector 4; the connecting component is used to fix the main terminal connector 3 and the secondary terminal connector 4; and a limit component is provided inside the protective shell 1.
[0027] The connecting assembly includes a first housing 11, which is disposed on the top of the terminal secondary connector 4. A first mounting block 12 is fixedly connected to one side of the first housing 11. The first mounting block 12 and the terminal secondary connector 4 are installed by screws. A receiving groove is provided on one side of the first housing 11. A vertical plate 14 is fixedly connected inside the receiving groove. A first mounting rod 15 is fixedly connected inside the vertical plate 14. Two locking plates 13 are slidably connected to the outside of the first mounting rod 15. A first spring 16 is provided on one side of each of the two locking plates 13.
[0028] The top of the terminal main connector 3 is provided with a second housing 17, and a second mounting block 18 is fixedly connected to one side of the second housing 17. The second mounting block 18 is installed with the terminal main connector 3 by screws. The interior of the second housing 17 has two through slots 19. The outer side of the retaining plate 13 is slidably connected to the interior of the through slots 19, and one side of the retaining plate 13 is in contact with one side of the second housing 17.
[0029] The second housing 17 has an installation groove 20 inside, and a second installation rod 22 is fixedly connected inside the installation groove 20. Two abutment plates 21 are slidably connected to the outside of the second installation rod 22. A second spring 23 is provided between one side of the two abutment plates 21. One side of the abutment plate 21 abuts against one side of the clamping plate 13.
[0030] In the above technical solution, considering that each set of terminals in the terminal connector for the electrical automation equipment requires screwing for fixing and disassembly, which increases the time cost of equipment assembly and maintenance, the specific operation is as follows: The first housing 11 is installed on the top of the secondary terminal connector 4 using screws, and the second housing 17 is installed on the top of the main terminal connector 3. When the secondary terminal connector 4 and the main terminal connector 3 are connected using the connecting assembly, the insert plate 8 corresponds to and connects with the slot 7. When the inclined surface of the retaining plate 13 contacts the corner of the through groove 19, continued force is applied, thereby pushing the retaining plate 13 open, compressing the first spring 16 until the retaining plate 13 passes through the through groove 19, and simultaneously the corner of the retaining plate 13 contacts the abutment plate 21. When the inclined plate contacts the main connector 3, it directly pushes open the clamping plate 21, compressing the second spring 23. Once the secondary connector 4 and the main connector 3 are fully engaged, one end of the retaining plate 13 passes through the second housing 17. The retaining plate 13 is no longer under pressure and, under the rebound of the first spring 16, returns to its original position. One end of the retaining plate 13 contacts one side of the second housing 17. Simultaneously, under the rebound of the second spring 23, the clamping plate 21 presses against one side of the retaining plate 13, thus securing it. This allows the secondary connector 4 and the main connector 3 to be installed together. When separation is required, simply press one end of the retaining plate 13 by hand to push it out of the through slot 19, separating the secondary connector 4 from the main connector 3. By using a quick-locking mechanism with springs and fasteners, the assembly and maintenance efficiency of the terminal connectors is greatly improved, eliminating the need for bolt tightening. This significantly shortens assembly and disassembly time and makes operation simpler and easier to master.
[0031] Reference Figures 1 to 6In a preferred embodiment, the limiting component includes a first rubber plate 24, which is fixedly connected inside the protective shell 1. A third spring 25 is fixedly connected at equal intervals to the bottom of the cover plate 9. A second rubber plate 26 is fixedly connected to the bottom of the third spring 25. The bottom of the second rubber plate 26 and the top of the first rubber plate 24 both abut against the outer side of the secondary connecting line 6. Two positioning rods 27 are fixedly connected to the top of the first rubber plate 24, and two positioning holes are opened at the bottom of the second rubber plate 26. After the terminal secondary connector 4 is connected to the terminal main connector 3, the secondary connecting line 6 is placed in the first rubber plate 24, and then the cover plate 9 is closed. The positioning rods 27 are aligned with the positioning holes, so that the second rubber plate 26 can be completely fitted with the first rubber plate 24. Then, the third spring 25 is used to make the second rubber plate 26 cover the secondary connecting line 6, protecting the connecting line and the interface and reducing loosening caused by vibration.
[0032] Reference Figures 1 to 6 In a preferred embodiment, baffles 10 are fixedly connected at equal intervals to the bottom of the cover plate 9; by setting baffles 10, the gap between the secondary connection line 6 and the protective shell 1 can be effectively blocked, thereby preventing dust from entering the interior of the protective shell 1 and protecting the connector.
[0033] Working principle: In use, the first housing 11 is installed on top of the terminal secondary connector 4 using screws, and the second housing 17 is installed on top of the terminal main connector 3. When the terminal secondary connector 4 and the terminal main connector 3 are connected using the connecting assembly, the insert plate 8 corresponds to and connects with the slot 7. When the inclined surface of the retaining plate 13 contacts the corner of the through groove 19, continued force is applied, thereby pushing the retaining plate 13 open, and the first spring 16 is compressed until the retaining plate 13 passes through the through groove 19. At the same time, the corner of the retaining plate 13 contacts the inclined plate part of the abutment plate 21, which directly pushes the abutment plate 21 open, and the second spring 23 is also compressed. When the terminal secondary connector 4 and the terminal main connector 3 are fully fitted, one end of the retaining plate 13 passes through the second housing 17, and the retaining plate 13 is no longer under pressure. Under the rebound of the first spring 16, the retaining plate 13 returns to its original position. One end of the terminal connector 26 will contact one side of the second housing 17. At the same time, the clamping plate 21, under the rebound of the second spring 23, will press against one side of the clamping plate 13, thereby abutting the clamping plate 13. In this way, the terminal secondary connector 4 and the terminal main connector 3 can be installed together. The secondary connecting wire 6 is placed in the first rubber plate 24, and then the cover plate 9 is closed. The positioning rod 27 is aligned with the positioning hole, so that the second rubber plate 26 can be completely attached to the first rubber plate 24. Then, the third spring 25 is used to make the second rubber plate 26 cover the secondary connecting wire 6. When it is necessary to separate them, just press one end of the clamping plate 13 by hand, so that the clamping plate 13 can be pushed out from the through slot 19, and the terminal secondary connector 4 and the terminal main connector 3 can be separated. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
