Detailed Description

The utility model discloses a terminal for an electric heater of a continuous annealing furnace, which can stably conduct electricity and is simple to maintain.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In an embodiment of the present invention, the terminal for the electric heater of the continuous annealing furnace includes a terminal body 1 and a terminal plate 2. The material of the binding post body 1 is heat-resistant steel. The material of the wire connection plate 2 is also heat-resistant steel. The heat-resistant steel has higher strength and good chemical stability at high temperature. Compare in the wire connection disc 2 of copper material among the prior art, the difficult emergence of the wire connection disc 2 of heat-resisting steel material is out of shape in this embodiment. Therefore, the land 2 in the present embodiment is not easily deformed, and the land 2 and the post body 1 can be stably contacted, thereby ensuring the stability of the electrical conduction. In addition, the wiring disc 2 in the embodiment is sleeved on the wiring terminal, and the wiring disc 2 and the wiring terminal body 1 are welded. Therefore, the small parts such as the gasket are omitted, adhesion of the small parts such as the gasket is avoided, and maintenance difficulty is reduced.

Furthermore, the double-sided full-welding is adopted between the wiring plate 2 and the wiring terminal body 1. Two-sided full-length welding can improve the joint strength between wire connection plate 2 and the terminal body 1, can resist the external force that the in-process that receives at the dismouting, ensures wire connection plate 2 and the electrically conductive stability of terminal body 1.

Further, a patch panel 2 is connected with a patch pole 8. The terminal rod 8 is used for mounting a terminal lug. The wire lug is directly sleeved on the wiring rod 8. The terminal rod 8 may be plural. A plurality of terminal rods 8 are evenly arranged around the center of the terminal block 2.

Furthermore, the wire connecting rod 8 and the wire connecting plate 2 adopt single-side full welding. And the welding part of the single-side full welding is positioned on one side of the wire connecting disc 2, which is back to the wire connecting rod 8. I.e. there is no weld on the side where the wire-receiving nose is located. This ensures a sufficient contact area between the terminal lug and the land 2, thereby ensuring stability of the electrical conduction.

Further, along the axial direction of the terminal body 1, the terminal body 1 sequentially passes through the furnace shell 5, the fixing block 4 and the insulating block 3. The fixed block 4 is fixed on the furnace shell 5. The insulating block 3 is fixed on the fixing block 4. The terminal body 1 is tightly matched with the insulating block 3, and the terminal body 1 is supported by the insulating block 3. Gaps are reserved between the terminal body 1 and the fixed block 4 and between the terminal body 1 and the furnace shell 5, so that electric conduction between the terminal body 1 and the fixed block 4 or between the terminal body and the furnace shell 5 is prevented.

Further, the insulating block 3 is fixedly connected with the fixing block 4 through a connecting bolt 6. The connecting bolt 6 is provided along the axial direction of the terminal body 1. The connecting bolt 6 may be provided in plural numbers around the terminal body 1, thereby ensuring the firmness of the connection of the insulating block 3 and the fixing block 4.

Furthermore, a jacking bolt 7 penetrates through the insulating block 3. The jack bolts 7 are arranged along the radial direction of the terminal body 1. The puller bolt 7 is used for tightly pushing the terminal body 1 to prevent the puller bolt 7 from deflecting when being subjected to external force, so that the stability of the terminal body 1 is improved.

Further, the insulating block 3 is preferably a polyurethane insulating block 3. The polyurethane insulating block 3 has the advantages of good wear resistance, high mechanical strength, biological aging resistance and the like. The polyurethane insulating block 3 can provide a stable supporting force for the terminal body 1.

Further, an insulating sleeve 9 is sleeved outside the terminal body 1. The insulating sleeve 9 is positioned in the inner cavities of the furnace shell 5 and the fixed block 4. The insulating sleeve 9 further prevents the terminal body 1 from being in electrical contact with the furnace shell 5 and the fixing block 4, so that the stability of electric conduction is further improved.

Furthermore, a groove is formed on the end surface of the insulating block 3 close to the insulating sleeve 9. The opening of the groove faces the insulating sleeve 9, and the end part of the insulating sleeve 9 extends into the groove. The arrangement can further ensure that the terminal body 1 does not electrically contact with the furnace shell 5 and the fixing block 4. If there is no groove, there may be a gap between the insulating sleeve 9 and the insulating block 3, and the terminal body 1 in the gap is exposed, so that there may be an electrical contact with the furnace shell 5, the fixing block 4 or other electrical conductors, which may result in instability of electrical conduction.

Further, the material of the insulating sleeve 9 is preferably a ceramic insulating sleeve 9. The ceramic insulating sleeve 9 is convenient to use and high in cost performance.
