Abstract

The invention relates to an electric switch and a copper bar, in particular to a temporary electric quick connector for a switch copper bar, which aims to solve the problems that when a copper wiring terminal and a crimping pliers corresponding to the switch and the copper bar are not prepared in advance, the temporary electric wiring is not more than 100A, screws are required to be frequently disassembled and assembled, the screw hole of the switch is easy to slip, and an accident is caused by poor contact due to direct wiring of an electrician because materials and tools cannot be prepared in advance.

Description

Temporary electricity utilization quick connector for switch copper bar

Technical Field

The invention relates to an electric switch and a copper bar

Background

A lot of current three-phase switches and copper bar wire are directly with the screw-on the switch, and the wire inserts the switch and need use copper binding post to use the wire crimper line ball, perhaps directly twine on the screw and do the ring, fasten again.

Disclosure of Invention

1. The invention needs to solve the problems that when a copper wiring terminal and a crimping pliers corresponding to a switch and a copper bar are not prepared in advance, the temporary power utilization wiring of not more than 100A is not required, the wiring of the copper wiring terminal is stable and convenient to fasten, the passing of heavy current is facilitated, but the temporary power utilization switching and the crimping pliers are time-consuming, the temporary power utilization switching and the crimping pliers cannot be prepared in advance due to the uncertainty of temporary power utilization, an electrician often directly winds a lead on a screw to form a ring and then fastens the lead, the lead is easy to be broken and deformed by directly winding a lead to form the ring and fastening the lead, the contact is poor and the heating is caused, and accidents are caused

2. The temporary wiring corresponding to the switch and the copper bar has two shapes, the corresponding switch is a flat copper bar, one end of the copper bar is provided with a hole, a screw wiring terminal is used at one end of the copper bar, the hole of the copper bar is connected with the switch and the copper bar with reserved screw hole positions, the screw wiring terminal is connected with a lead in a pressing mode, the copper bar corresponding to the copper bar without the reserved screw hole positions is welded on a copper metal plate, an iron metal plate with the same length and width as the copper metal plate is additionally arranged, and the copper metal plate and the iron metal plate are clamped and fixed by screws to the copper

3. When the temporary wiring terminal is used for temporary wiring of a switch and a copper bar, the temporary wiring terminal not only has stable connection of a copper wiring terminal and is convenient to fasten, but also can be fixed on the switch copper bar to be directly connected with a lead, and can also be used as a fixed semi-permanent wiring port, so that the condition that the screw is frequently removed and tightened when temporary electricity is used, the screw thread in the switch is easy to slip, the switch is unstable in wiring and needs to be replaced is considered, the switch replacement rate is reduced, and the service life of the switch is prolonged.

Drawings

FIG. 1 is a diagram of a copper bar with a corresponding switch and a hole having a reserved screw; FIG. 2 is a copper bar diagram of a hole without reserved screws.

Detailed Description

The corresponding switch is a flat copper bar, one end of the copper bar is provided with a hole, a screw connecting terminal is used at one end of the hole, the thickness of the copper bar is 2mm, the width of the copper bar is determined according to the current-carrying capacity and the aperture size of the copper bar, the mechanical strength is determined, the shape of the copper bar is determined by insulation, the aperture of the hole is opened according to the aperture of a switch screw below 100A, the copper bar and the connecting terminal are integrally installed in a formed insulating shell, the copper bar corresponding to the copper bar is welded on a copper metal plate, a ferrous metal plate with the same length and width as the copper metal plate is additionally arranged, the screw connecting terminal is used at one end of the copper bar, the thickness of the copper bar is 2mm, the width of the copper bar is determined according to the current-carrying capacity and the aperture size of the copper bar, the copper metal plate is concave, the depth of the concave is 2mm, the concave width is 3cm, copper bar and copper metal plate, iron metal plate remove laminating copper bar department and all install in fashioned insulating casing.

Claims

1. The switch is corresponding to a flat copper bar, one end of the flat copper bar is provided with a hole, the screw wiring terminal is used at one end of the opened hole, the thickness of the copper bar is 2mm, the width of the copper bar is determined according to the current-carrying capacity and the aperture size of the copper bar, the mechanical strength is determined, the shape is determined by insulation, the aperture of the opened hole is opened according to the aperture of the switch screw below 100A, and the copper bar and the wiring terminal are integrally installed in a formed insulating shell.

2. What correspond the copper bar is that a copper bar welds on copper metal plate, plus one and the same iron metal plate of copper metal plate length and width size constitute, screw binding post is used to copper bar one end, the thickness of copper bar is 2mm, the width is according to copper bar current-carrying capacity and aperture size, mechanical strength is confirmed, copper metal plate indent, the indent degree of depth is 2mm, the indent width is 3cm, the rectangle can laminate with the copper bar easily, both sides respectively have a screw hole about outside the copper metal plate indent part, iron metal plate corresponds 2 screw hole site departments trompil of copper metal plate, it is fixed with copper bar clamp with copper metal plate and iron metal plate to make copper metal plate and iron metal plate press from both sides, accomplish effective connection, copper bar and copper metal plate, iron metal plate is except that laminating copper bar department all install in fashioned insulating casing.

3. The size and the shape of the copper sheet of the temporary electricity utilization quick connector of the switch copper bar are determined according to the current-carrying capacity and the mechanical strength of the copper sheet, and other conductive metals can be used for replacing the copper sheet.

4. The opening size of the temporary electricity utilization quick connector of the switch copper bar is determined according to the size of a common switch screw.

5. The size of the copper metal plate and the iron metal plate of the temporary electric quick connector for the switch copper bar is determined by mechanical strength, and other conductive metals can be used for replacing the copper metal plate and the iron metal plate.

6. The appearance insulation of the temporary electricity utilization quick connector of the switch copper bar is necessary to use in view of safety.

7. The invention relates to a material for a temporary electric quick connector for a switch copper bar, which is a common material in the market.
