Description

Technical Field

[0001] This utility model relates to the technical field of terminal triggering devices, and in particular to a terminal triggering device. Background Technology

[0002] In existing technologies, terminal blocks are key components in electrical connections, used to safely and reliably connect wires, ensure circuit continuity, and facilitate installation, maintenance, and expansion. Their core functions include conducting electricity, insulating, and fixing wires, but they do not have fault indication functions. When a fault occurs in the wires connected to them, on-site troubleshooting is often required. The more terminal blocks there are on-site, the longer the troubleshooting time becomes, greatly increasing the time required for emergency repairs of electrical equipment and secondary circuit faults.

[0003] To address the problem caused by a cable fault on one side of the terminal block, a triggering device needs to be installed inside the terminal block to activate the fault light circuit and illuminate it upon the occurrence of a fault in the cable on that side. To overcome these drawbacks, this invention provides a terminal block triggering device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a terminal triggering device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a terminal triggering device, comprising a first housing, a support frame fixedly connected to the rear side inside the first housing, a magnetic suction assembly fixedly connected to the front end of the support frame, limit rods fixedly connected to both sides inside the first housing, a second housing inserted and connected to the front side of the first housing, connecting seats fixedly connected to both ends of the inner side of the second housing, the connecting seats being slidably connected to the corresponding limit rods, an iron block fixedly connected to the front side inside the second housing, and a sliding energizing assembly provided between the magnetic suction assembly and the second housing.

[0006] Furthermore, a second fixing seat is fixedly connected to both ends of the rear side of the first housing.

[0007] Furthermore, a first fixing seat is fixedly connected to the front side of the upper end of the second housing.

[0008] Furthermore, the magnetic suction assembly includes a connecting cover fixedly connected to the support frame, and an iron core is fixedly connected inside the connecting cover.

[0009] Furthermore, a coil is wound around the outside of the iron core, one end of the coil is fixedly connected to a third connecting wire, the other end of the coil is fixedly connected to a fourth connecting wire, and one end of the third connecting wire passes through the first housing and is fixedly connected to a second connecting wire.

[0010] Furthermore, the sliding energized assembly includes a brush and a conductive rail. The brush is fixedly connected to one end of the fourth connecting line, and the conductive rail is fixedly connected to the bottom end inside the second housing. The brush and the conductive rail are slidably connected.

[0011] Furthermore, a first connecting line is fixedly connected to one end of the conductive rail, and a card holder is fixedly connected to one end of the first connecting line.

[0012] The beneficial effects of this utility model are:

[0013] In use, the terminal triggering device of this utility model has a card holder in contact with the grounding terminal. A conductive sheet is fixedly connected to the first fixed seat. When the terminal is not faulty, no current flows between the second connecting wire, the third connecting wire, the coil, the fourth connecting wire, the brush, the first connecting wire, the card holder, and the grounding terminal, and the terminal works normally. When a fault occurs in the circuit on one side of the terminal, the current forms a circuit through the resistor, the second connecting wire, the third connecting wire, the coil, the fourth connecting wire, the brush, the first connecting wire, the card holder, and the grounding terminal. At this time, the coil is energized, the iron core generates a magnetic field, attracts the iron block, and thus drives the second housing to slide along the limit rod through the connecting seat. This causes the card holder to disengage from the grounding terminal and moves the conductive sheet, making the circuit of the fault light conduct, and thus causing the fault light to light up.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-6 As shown, a terminal triggering device is disclosed, comprising a first housing 1, a support frame 8 fixedly connected to the rear side inside the first housing 1, a magnetic suction assembly 9 fixedly connected to the front end of the support frame 8, limit rods 13 fixedly connected to both sides inside the first housing 1, a second housing 2 inserted and connected to the front side of the first housing 1, a connecting seat 15 fixedly connected to both ends inside the second housing 2, the connecting seat 15 being slidably connected to the corresponding limit rod 13, an iron block 14 fixedly connected to the front side inside the second housing 2, and a sliding energizing assembly provided between the magnetic suction assembly 9 and the second housing 2.

[0025] As shown in the figure, the first housing 1 is fixedly connected to the second fixing seat 6 at both ends of the rear side, and the second housing 2 is fixedly connected to the first fixing seat 3 at the front of the upper end. The first housing 1 can be fixed by the second fixing seat 6, and a conductive sheet is fixedly connected to the first fixing seat 3.

[0026] As shown in the figure, the magnetic attraction component 9 includes a connecting cover 19 fixedly connected to the support frame 8. An iron core 17 is fixedly connected inside the connecting cover 19. A coil 18 is wound around the outside of the iron core 17. One end of the coil 18 is fixedly connected to a third connecting wire 10, and the other end of the coil 18 is fixedly connected to a fourth connecting wire 11. One end of the third connecting wire 10 passes through the first housing 1 and is fixedly connected to a second connecting wire 7. The sliding energizing component includes a brush 12 and a conductive rail 16. The brush 12 is fixedly connected to one end of the fourth connecting wire 11. The conductive rail 16 is fixedly connected to the bottom of the second housing 2. The brush 12 and the conductive rail 16 are slidably connected. One end is fixedly connected to the first connecting line 4, and the other end of the first connecting line 4 is fixedly connected to the card holder 5. When a fault occurs in the circuit on one side of the terminal block, the current passes through the resistor, the second connecting line 7, the third connecting line 10, the coil 18, the fourth connecting line 11, the brush 12, the first connecting line 4, the card holder 5 and the grounding terminal to form a circuit. At this time, the coil 18 is energized, the iron core 17 generates a magnetic field, attracts the iron block 14, and thus can drive the second housing 2 to slide along the limit rod 13 through the connecting seat 15. The brush 12 slides with the conductive rail 16. The first connecting line 4 and the fourth connecting line 11 are both hard wires that are not easily deformed.

[0027] Working principle: During use, the card holder 5 is in contact with the grounding terminal. A conductive sheet is fixedly connected to the first fixed seat 3. When there is no fault in the wiring terminal, no current flows between the second connecting line 7, the third connecting line 10, the coil 18, the fourth connecting line 11, the brush 12, the first connecting line 4, the card holder 5, and the grounding terminal. The wiring terminal works normally. When a fault occurs in the circuit on one side of the wiring terminal, the current forms a circuit through the resistor, the second connecting line 7, the third connecting line 10, the coil 18, the fourth connecting line 11, the brush 12, the first connecting line 4, the card holder 5, and the grounding terminal. At this time, the coil 18 is energized, and the iron core 17 generates a magnetic field, attracting the iron block 14. This allows the second housing 2 to slide along the limit rod 13 through the connecting seat 15. The brush 12 slides with the conductive rail 16, which allows the card holder 5 to disengage from the grounding terminal and moves the conductive sheet, thus making the circuit of the fault light conduct and causing the fault light to light up.
