Embodiment 1

[0021] Such as figure 1 As shown, the special junction box for flexible heating appliances of the present invention includes three parts: an upper cover 1 , a junction board 4 and a bottom board 4 , which are fixedly connected together by screws 6 . There are five parallel wiring slots on the terminal board 4 in the middle, among which the outermost wiring slots on both sides are the thermostat wiring slots 3, which are used to connect the wiring heads of the thermostat; the middle wiring slot is the zero line connection Slot 7, on both sides of the zero line junction slot are two live wire junction slots 8, and a communication slot 10 is respectively arranged between the zero line junction slot 7 and the two live wire junction slots 8. The front and rear ends of the live wire junction slot 8 and the thermostat junction slot 3 are respectively provided with inlets for power supply hot wire connectors and power cord connectors. A bead 2 that can be embedded in the notch is buc...

Embodiment 2

[0026] This embodiment is a single-channel single-control junction box, and its overall structure is basically the same as that of Embodiment 1, except that the structure of the junction board 4 is different.

[0027] Such as figure 2 As shown, the wiring board 4 is provided with three juxtaposed wiring slots, of which the right one is the thermostat wiring slot 3 for connecting the thermostat wire connector, the middle one is the neutral wire wiring slot 7, and the left one is the live wire wiring Slot 8. A communication slot 10 is provided between the neutral line junction slot 7 and the live line junction slot 8 . The front and rear ends of the live wire junction slot 8 and the thermostat junction slot 3 are respectively provided with inlets for power supply hot wire connectors and power cord connectors. Two threading openings 9 are arranged on the wiring board 4 , and the threading openings 9 are also diamond-shaped openings, which are respectively arranged at the rear ...

Abstract

The invention relates to a special junction box for a flexible heater. The special junction box comprises an upper cover, a wiring board and a base board, wherein a power line wiring groove, a zero line wiring groove and a temperature controller wiring groove are arranged on the wiring board; the power line wiring groove, the zero line wiring groove and the temperature controller wiring groove are arranged in parallel; and a communication groove is arranged between the power line wiring groove and the zero line wiring groove. According to the invention, the application of a zero radiation electric heating wire becomes possible, and the mechanical production of a flexible heater becomes possible. The flexible heater using the junction box provided by the invention can realize multi-gear control, variable heating temperature and one-group or multi-group control, can be used by a common electric heating wire or zero radiation wire, and can also be used in a range of safety voltages from an alternating current 220V to an alternating current 50V.

Description

technical field [0001] The invention relates to a power junction box, in particular to a special junction box for flexible heating appliances. Background technique [0002] Generally, a receiving box is arranged on the flexible heating appliance to connect the built-in heating wire and the external power wire. The common electric heating wire is a single-wire structure, which is coiled in a flexible heating appliance in a serpentine shape. The problem that this heating wire exists is that strong electromagnetic radiation will be produced after electrification, which will have adverse effects on the human body. [0003] At present, a zero-radiation heating wire has been invented, which is used in flexible heating appliances to overcome the adverse effects of using ordinary heating wires on the human body. The structure of this zero-radiation heating wire is that an inner and outer double-layer helix is ​​arranged in a heating wire—one layer is a heating wire, and the other ...
