Technical Field

[0001] The utility model relates to the technical field of electric wire connection structures, in particular to a connection structure between furnace wire leads and power transmission wires used in a glass tempering heating furnace. Background Art

[0002] In the prior art, the connection method of the furnace wire lead and the power transmission line of the glass tempering heating furnace is mostly to form a clamping body with two separate conductive connecting clamps, and then clamp the lead wire through four bolt groups. One of the two separate conductive connecting clamps can be connected to the connecting nose of the crimped power transmission line through the bolt group, and then a connection structure of the furnace wire lead and the power transmission line is formed. The main problems of this structure during use are:

[0003] 1. Because it is composed of two separate conductive wiring clamps to form a clamping body, the power transmission wire clamp wastes conductive materials and is relatively complicated to manufacture;

[0004] 2. Two separate conductive terminal clamps form a clamping body, which requires four bolt groups to clamp and tighten the furnace wire lead, which is cumbersome to assemble and has low production efficiency;

[0005] 3. Two separate conductive wiring clamps form a clamping body. To ensure that the wire clamp and the furnace wire lead are firmly clamped, a certain assembly gap must be retained on both sides, which leads to a small contact area between the conductive wire clamp and the lead. This connection method has poor conductivity and can easily cause excessive heat at the contact point, which has a great impact on the heating efficiency and electrical safety of the heating furnace.

[0008] Furthermore, the fixing plate, the circular ring sleeve and the conductive wiring clamp are an integrated structure.

[0009] Furthermore, the conductive connecting clips and the fixing plate on the left and right sides of the compression gap are arranged parallel to each other.

[0010] Furthermore, the inner diameter of the circular ring sleeve is 1-1.5 times the outer diameter of the furnace wire lead.

[0011] Furthermore, the number of the through-holes on the conductive wiring clamp and the fixed plate is multiple, and the multiple through-holes are evenly arranged on the conductive wiring clamp and the fixed plate.

[0012] Furthermore, the conductive connecting clip is in an L-shaped structure, and the L-shaped conductive connecting clip includes a first flat section and a second flat section that are perpendicularly arranged to each other, and a circular ring sleeve is connected to the end of the first flat section.
