Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent switches, and in particular relates to a programmable digital intelligent switch. Background Art

[0002] When the switch is in use, the live wire needs to be inserted into the internal connection port and then fixed with a locking screw. However, after the live wire is fixed in the connection port, the connection between the live wire and the switch is exposed to the outside air. Dust and moisture in the outside air may adhere to the surface of the connection between the live wire and the switch, causing the switch to short-circuit during use. When the locking screw is loose, the live wire may fall off from the connection port. Therefore, a programmable digital intelligent switch is needed to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a programmable digital intelligent switch to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a programmable digital intelligent switch, comprising a switch body, both sides of the switch body are provided with connection ports, the switch body is internally threaded with two locking screws, two protective components are arranged in the switch body, the protective components include a protective pad, an anti-slip sleeve and a conical hole, the two conical holes are respectively provided on the sides of the two protective pads away from each other, the two anti-slip sleeves are both clamped in the protective pads, and the two protective pads are both clamped in the connection ports.

[0005] As a preferred implementation, a copper wire bus port and a phase line sampling port are provided on the front side of the switch body.

[0006] As a preferred implementation, a neutral line connection port is provided on one side of the switch body, and an RS485 communication interface is provided on the other side of the switch body.

[0007] As a preferred implementation, the neutral line connection port is provided with two sockets, and the RS485 communication interface is provided with three sockets.

[0008] As a preferred implementation, a manual operation button is provided on the upper surface of the switch body.

[0009] As a preferred implementation, a relay status indicator light and an RS485 signal indicator light are provided on the upper surface of the switch body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model is provided with a protective pad, an anti-slip sleeve, a tapered hole, a connecting port and a locking screw. When the live wire is inserted into the connecting port, the live wire will move into the tapered hole and squeeze the protective pad, causing the protective pad to deform. Then, the moving live wire moves into the anti-slip sleeve and passes through the anti-slip sleeve to move below the locking screw. When the locking screw fixes the live wire in the connecting port, the protective pad and the anti-slip sleeve cooperate with each other to seal the gap between the live wire and the connecting port, so that it is not easy for external moisture and dust to enter the connecting port from the gap between the live wire and the connecting port and then adhere to the surface of the connecting part between the switch and the live wire, so that the switch is not easy to short-circuit during use. In addition, the anti-slip sleeve and the protective pad cooperate with each other to increase the friction between the live wire and the connecting port, so that the live wire is not easy to fall off from the connecting port due to the loosening of the locking screw, so that the live wire can be stably connected to the switch.

[0012] The utility model is provided with a copper wire bus port and a phase line sampling port, which add two splicable interfaces to the switch, and multiple switches can be combined into an integral multi-way switch for use, so that the switch can be used individually or in combination as a whole, thereby improving the applicability of the switch.
