Abstract
The utility model relates to an electric connection structure of a heating device, which comprises a connecting terminal connected to an electric input end of a heating device, and a rivet fixedly connecting the connecting terminal together with the electric input end, wherein an elastic metal washer slightly forming a chrysanthemum shape is arranged between the connecting terminal and the electric input end of the heating device, and the elastic metal washer can connect the connecting terminal and the electric input end of the heating device into a whole. Because the utility model adopts a structure that the elastic metal washer is arranged between the connecting terminal and the electric input end of the heating device, the connecting terminal of the utility model and the electric input end always keep close contact by the elastic metal washer. Moreover, the elasticity formed by the structure of a slight chrysanthemum shape can be used effectively for achieving the goal of preventing the occurrence of loosening of the connection structure between the connecting terminal and the electric input end. Consequently, the utility model eliminates the influence of heat expansion and cold contraction effectively, ensures the reliability of the connection structure, and extends the service life.
Description
Technical field
The utility model relates to a kind of electric connection structure of electro-heat equipment.
Background technology
The electric connection structure of existing electro-heat equipment generally is will realize with the fixing riveted joint of the electrical input of the heating sheet of electro-heat equipment with the binding post that power supply connects by rivet.Though the electric connection mode process structure of this structure is simple, realization is easy, but also there is such problem in actual use in it: after element inserts heavy current, owing to be subjected to self long-term, frequent influence of expanding with heat and contract with cold, make the syndeton between the element take place easily to become flexible, cause poor electric conductivity, resistance value between its contact-making surface to increase; At last, cause whole syndeton to be blown, the electro-heat equipment cisco unity malfunction.Therefore, existing this electric connection structure exists and connects problem unreliable, that useful life is short.
Summary of the invention
The purpose of this utility model is to provide a kind of connection reliable, long service life, and electric connection structure simple in structure, that production cost is low.
The technical solution of the utility model is achieved in that a kind of electric connection structure of electro-heat equipment, comprise on the electrical input that is connected in electro-heat equipment binding post and with binding post with the fixedly connected rivet of electrical input, its characteristics are to be provided with between the electrical input of described binding post and electro-heat equipment and both can be connected the elastic metallic packing ring that one slightly is chrysanthemum type.
For guaranteeing that further this contact resistance of elastic metallic packing ring and electro-heat equipment can not produce phenomenon overheated and fusing in a small range, above-mentioned elastic metallic washer face is provided with a silver coating.
More reliable in order further to guarantee syndeton of the present utility model, the bottom of above-mentioned electrical input is provided with between the bottom of rivet can effectively guarantee between it copper washer of riveted joint reliably.
The utility model is owing to adopt to be provided with between the electrical input of binding post and electro-heat equipment and both can be connected the structure that one slightly is the elastic metallic packing ring of chrysanthemum type, make binding post of the present utility model remain tight contact by this elastic metallic packing ring with electrical input, and effectively utilize it and slightly be chrysanthemum type elasticity that structure forms to reach the generation that prevents syndeton between it loosening, thereby eliminated the influence of expanding with heat and contract with cold effectively, guarantee the reliability of its syndeton, prolonged useful life.Simultaneously by guaranteeing further that in the structure that silver coating is set on the elastic metallic packing ring contact resistance between elastic metallic packing ring and the electro-heat equipment remains on small range, thereby can not become big heating, overheated and blow total because of contact resistance value, even because this moment when long-time high temperature uses, the oxide that elastic metallic gas ket surface produces also is the good conductor of electricity.
Below in conjunction with accompanying drawing the utility model is further described:

Fig. 2 is the local structure for amplifying schematic diagram of the A-A of Fig. 1;
Fig. 3 is the B-B sectional structure schematic diagram of Fig. 2.
Embodiment
As Fig. 1～shown in Figure 3, the electric connection structure of a kind of electro-heat equipment described in the utility model, it comprise on the electrical input 2 that is connected in electro-heat equipment 1 binding post 3 and with binding post 3 with the fixedly connected rivet 4 of electrical input 2.Be the problem that effectively solves that the existing existing connection of electric connection structure is unreliable, useful life is short etc., be provided with the elastic metallic packing ring 5 that slightly is chrysanthemum type that both can be connected one between the electrical input 2 of binding post 3 described in the utility model and electro-heat equipment 1.Make binding post of the present utility model remain tight contact by this elastic metallic packing ring with electrical input, and effectively utilize it and slightly be chrysanthemum type elasticity that structure forms to reach the generation that prevents syndeton between it loosening, thereby eliminated the influence of expanding with heat and contract with cold effectively, guarantee the reliability of its syndeton, prolonged useful life.This moment is for further to guarantee that the contact resistance between elastic metallic gas ket and the electro-heat equipment has a small range, above-mentioned elastic metallic packing ring (5) surface is provided with a silver coating, even like this when long-time high temperature uses, elastic force metal gas ket 5 surfaces produce the good conductor that oxide also is an electricity, thereby make the contact resistance between elastic metallic packing ring 5 and the electro-heat equipment 1 remain on small range, thereby can not become big heating, overheated and blow total because of contact resistance value.More reliable in order further to guarantee syndeton of the present utility model, the bottom of described electrical input 2 is provided with between the bottom of rivet 4 can effectively guarantee between it copper washer 6 of riveted joint reliably, and making the utility model strengthen rivet 4 effectively by this copper washer 6 can connect as one both more stable and reliably.For binding post 3 can be riveted on the electrical input 2 easily, described binding post 3 is for being connected with the ring-like terminal that has perforation of electric wire, and wherein said rivet 4 is a tubular rivet.
