Abstract
The invention relates to a connection mode of an electric heater. A metal casing is arranged between a post head of the electric heater and a conducting wire as a connecting piece. The inner wall at one end of the metal casing is provided with screw threads and the middle part is provided with a slot hole. The end of the inner wall of the metal casing provided with the screw threads is connected with the post head of the electric heater. The post head end of the electric heater extends into the slot hole in the middle part of the metal casing. The conducting wire is perforated and covered to the slot hole from the other end of the metal casting. The post head and the conducting wire are weldedly connected at the slot hole and weldedly connected together with the edge of the slot hole. One end of the metal casing is weldedly fixed with the post head and the other end of the metal casing is pressure weldedly fixed with the conducting wire. At least a fibre glass braided tube and a Silastic heat-resistant contraction pipe are arranged on a bare conductor of the connection section between the post head and the conducting wire for insulation. The invention has the advantages of scientific and convenient method and easy use. The invention can be broadly applied to the connection jointing of various electric heaters as well as be broadly applied to the installation jointing of various electric appliance connections.
Description
Technical field
The present invention relates to the electrical bar connection bolt and the lead ways of connecting of a kind of mode of connection of electric heater, particularly electric heater, belong to the electric heater technical field.
Background technology
It is fastening that traditional electric heater mode of connection mostly adopts binding post (double-screw bolt) to connect, and is about to lead and is wound on the binding post, is nested with pad then and screws nut on binding post.Though this mode of connection is convenient, the shortcoming of following several respects is arranged: 1, energising back bolt, nut, the lead oxidation, loosening of easily generating heat, of long duration also easily produce spark, be directed at outage or breaking out of fire; 2, Luo Lu lead, bolt, nut easily cause electric shock accidents; 3, the easily sliding tooth of nut overtorquing is twisted easy generation lead slippage outage phenomenon too loose.
Summary of the invention
The objective of the invention is to provide a kind of easy-to-connect, safe in utilization, can prevent that wiring is loosening, the mode of connection of the electric heater of oxidation.
The object of the present invention is achieved like this: the mode of connection of electric heater, it is characterized in that adopting metal sleeve between electric heater binding post and the lead is connector, metal sleeve one end inwall is provided with screw thread, the middle part is provided with slotted eye, the end that the metal sleeve inwall is provided with screw thread is screwed on the electric heater binding post, electric heater wiring styletable extends the slotted eye place at metal sleeve middle part, lead wears to slotted eye from the other end of metal sleeve, binding post and lead are welded to connect at the slotted eye place of metal sleeve and are connected together in succession with the slotted eye side weld of metal sleeve, the end and the binding post welding that are screwed in the metal sleeve on the electric heater binding post are fixing, the end and the conductor compression jointing that are set on the lead are fixed, and are provided with the insulation of fiberglass braided tube and silicon rubber heat-resisting collapsible tube at least on the bare exposed conductor of binding post and lead linkage section.
Described slotted eye is oval.Described metal sleeve is the stainless steel sleeve pipe.
The present invention is rational in infrastructure, and method is easy.Owing to be nested with metal sleeve at lead and bolt junction, metal sleeve and lead, binding post weld at the slotted eye place, the two ends of metal sleeve are fixed with binding post, wire bonds and crimping respectively, and lead and binding post are connected firmly, and avoid getting loose, oxidation and influence electric conductivity.On the bare exposed conductor of binding post and lead linkage section, be nested with the insulation of fiberglass braided tube and silicon rubber heat-resisting collapsible tube.Avoided lead exposed, prevented to get an electric shock, also do not produced spark, safe and convenient to use, the wiring that can be widely used in various electric heaters connects.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: lead 1, metal sleeve 2, binding post 3, slotted eye 4, nut 5, pad 6, fiberglass braided tube 7, silicon rubber heat-resisting collapsible tube 8,9, insulation porcelain seat 10.
Embodiment
On the binding post 3 of the electrical bar of electric heater, be nested with insulation porcelain seat 10 and pad 6 earlier, be tightened, guarantee that conductor does not touch with the electric heating tube shell joint with nut 5.Metal sleeve 2 adopts stainless steel tubes, at an end of metal sleeve 2 internal thread is set, and the middle part is provided with axial oval slotted eye 4.The end that metal sleeve 2 inwalls are provided with screw thread is screwed on the binding post 3 of electric heating tube, electric heating tube wiring styletable extends slotted eye 4 places at metal sleeve middle part, lead 1 wears to slotted eye 4 from the other end of metal sleeve, distance between wiring styletable and the conductor wire end (head) is about 2 millimeter, and binding post and lead are welded to connect at the slotted eye place of metal sleeve and are connected together in succession with the slotted eye side weld of metal sleeve.The end and the binding post welding that are screwed in the metal sleeve on the binding post of electric heating tube is fixing, and the end and the conductor compression jointing that are set on the lead are fixed.On the bare exposed conductor of binding post and lead linkage section, fiberglass braided tube 7 is set earlier, silicon rubber heat-resisting collapsible tube 8,9 is set on fiberglass braided tube again, and extends to the two ends of fiberglass braided tube 7 and silicon rubber heat-resisting collapsible tube 8,9 on the electric heating shell respectively and on the insulating case of lead.
Claims (3)
