Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically a splicing terminal block with anti-loosening function. Background Technology

[0002] After wiring is completed, existing terminal blocks are prone to detachment between the wiring holes and the wires. If the wiring of electrical equipment becomes loose and causes poor contact, it is very likely to increase the resistance at this point, leading to a rise in temperature and potentially causing an accident.

[0003] A patent (CN217642003U) discloses an anti-loosening terminal block, comprising a terminal block assembly including a terminal body, a terminal post disposed on the top of the terminal body, a terminal hole and a bolt hole disposed inside the terminal post, and a fixing bolt disposed inside the bolt hole; and a fixing component including a socket disposed inside the terminal post, a locking rod disposed inside the socket, and a cap disposed at one end of the locking rod. This technical solution solves the problem of loosening of existing terminal blocks due to vibration during operation. However, in this technical solution, the wire is horizontally inserted into the socket, and the wire is fixed only by the fixing bolt, which makes it easy for the wire to separate from the fixing bolt when the wire is pulled horizontally.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-5 A splicing terminal block with anti-loosening function includes a fixing part 1, with notches 2 on both sides of the fixing part 1. Bent metal terminals 3 are arranged inside the notches 2, and the metal terminals 3 on both sides are connected to each other. The fixing part 1 is covered by a cover plate 4 of the notches 2. The cover plate 4 is ultrasonically welded. The cover plate 4 has a through hole 5 at the notch 2. A threaded shaft 6 is threadedly connected to the middle of the cover plate 4. The metal terminals 3 are located in the notch 2 and are inclined upward to form a bendable bearing cavity 7. One side of the bearing cavity 7 is in contact with the fixing part 1, and the threaded shaft 6 is perpendicular to the other side of the bearing cavity 7. By adjusting the originally horizontally set bearing cavity 7 to be inclined upward, the wires in the bearing cavity 7 can also be inclined, thereby providing greater horizontal resistance when the wires are stretched horizontally, thus preventing the wires from loosening.

[0024] A metal pressure plate 8 is slidably connected to the middle of the cover plate 4. The metal pressure plate 8 is located between the threaded shaft 6 and the bearing cavity 7. This arrangement makes the compression of the bearing cavity 7 more uniform and the deformation of the bearing cavity 7 more uniform.

[0025] The metal terminals 3 on both sides are formed by bending a metal strip. In this technical solution, the width of the metal terminal 3 is limited, and the bending needs to be done after passing through the fixing part 1, which can reduce the structure of the device.

[0026] The metal terminals 3 on both sides are formed by bending two metal strips. The two metal terminals 3 overlap each other. This arrangement allows the metal terminals 3 to be bent before being inserted into the fixing part 1, thereby improving production efficiency.

[0027] The two notches 2 are connected and pass through each other by a through groove 9. The metal terminal 3 is placed inside the through groove 9. A groove 10 is provided in the middle of the bottom end of the fixing part 1. A positioning hole 11 that passes through the through groove 9 is provided inside the groove 10. When the metal terminal 3 is inserted into the through groove 9, the punch inserted into the positioning hole 11 is used to punch and deform the metal terminal 3 to form a protrusion that is stuck in the positioning hole 11, thereby positioning the metal terminal 3.

[0028] One end of the fixing part 1 is provided with a Chinese character-shaped insert 12, and the other end of the fixing part 1 is provided with a slot 13 for accommodating the Chinese character-shaped insert 12. The bottom end of the insert 12 is provided with an elastic protrusion 14, and the inside of the slot 13 is provided with a bearing groove 15 for accommodating the elastic protrusion 14. This arrangement can restrict the adjacent fixing parts 1 from being connected together to prevent shaking, and at the same time, the pressing of the elastic protrusion 14 and the bearing groove 15 can be used to position the fixing part 1.

[0029] The bottom end of the insert 12 is not on the same horizontal plane as the bottom end of the slot 13. The bottom end of the insert 12 is located below the bottom end of the slot 13. This arrangement allows the bottom part of the insert 12 to accommodate the part that compresses the insert 12, thereby facilitating the separation of the device.

[0030] In use, by adjusting the originally horizontally set bearing cavity 7 to be tilted upward, the wire inside the bearing cavity 7 can also be tilted, thereby providing greater horizontal resistance when the wire is stretched horizontally, thus preventing the wire from loosening.

[0031] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
