Abstract
The utility model discloses a sealed connecting piece of an end socket of an electrothermal element. One end of the utility model is connected with a guide rod, and the other end of the utility model is connected with the copper core of a conducting wire, and a connecting piece of the utility model is a tubular tail-shaped nut of which the tail part is provided with a groove. The outermost layer of the connecting piece is an acrylonitrile butadiene rubber sealing insulating layer used for sticking with a stainless steel pipe on the outermost layer, and an adhesive layer is arranged between the stainless steel pipe and an outer sleeve of the conducting wire. The utility model has the advantages firm connection, good electrical conductivity, low damage ratio, etc. The utility model is particularly suitable for the defrosting environment with large cold and heat variations, and large humidity.
Description
The utility model relates to a kind of termination seal connector of tubular metal electric heating element, is particluarly suitable for using in the environment of defrosting.
The tubular metal electric heating element is commonly called as electrothermal tube, and its primary structure is outside stainless steel tube, and spirality heating wire and insulating heat-conductive inserts in the pipe: the eduction rod of termination (line) links to each other with lead through connector.The defrosting electrothermal tube termination seal that first electric heater factory, Shengxian County, Zhejiang puts on market, connector between its eduction rod and the lead adopts the copper pipe first jaw member to realize, one section copper pipe, two ends lead to into eduction rod and lead respectively, firmly one press from both sides with pliers, one end of eduction rod and lead all is fixed in this copper pipe that presss from both sides into flat, this clamp is fixedly coupled part, easily get loose with the connecting portion of lead, easily loosening with being connected of eduction rod, cause loose contact, the heating oxidation, make the electric heating element conduction poor, the spoilage height.For making electric heating element adapt to the big requirement of the cold and hot temperature difference in the environment of defrosting and reach the purpose of waterproof insulation, the termination portion of this connector and whole heater element all uses rubber seal, and adhesive layer is arranged therebetween.
The purpose of this utility model be to overcome the deficiencies in the prior art and design a kind ofly be connected firmly, conductivity is good, spoilage is low connector, and the stronger termination seal connector of the waterproof insulating layer adhesion strength that makes termination portion, thereby further improve electric heating element in defrosting environmental applications performance.
The purpose of this utility model can realize by following measure: an end of connector is connected with eduction rod, the other end is connected with the copper core of lead, whole termination is the rubber seal insulating barrier with the outermost layer of connector, connector is a kind of nut, the rubber seal insulating barrier with in order to the stainless steel tube of set this layer, lead outward inner room adhesive layer is arranged.
The purpose of this utility model also can be come perfect by following measure: the preferably a kind of afterbody of nut that connects part has the tail shape nut of groove, and it and eduction rod one end are fixed with screw, and is welding between the copper core of lead; Adhesive layer is the Kai Muluoke adhesive layer.
Accompanying drawing is the utility model structural representation.
The utility model is described in detail below in conjunction with embodiment: the tubular metal electric heating element is in response to using the environment difference, can divide numerous species, shape and model are different, but its core texture is that alloy resistance wire 1 is arranged in the metal tube 2, the modified oxidized magnesium of good insulation properties is closely being filled in its gap, the two ends of heating wire have eduction rod 3 (line) and lead to join, and pass through wire connected power.The utility model is considered from the defrosting environment that is applied in icebox etc., then connector must firmly connect, good conductivity, spoilage is low, the tail shape nut 5 of this available one copper afterbody trough of belt connects part, fix with screw between one end of this nut 5 and the eduction rod 3, the stern notch of the other end can be in the centre of nut 5 transversal half, the rear portion is vertical cuts half, the whole nut of reject 1/4 and usefulness, the then fastening eduction rod 3 of the internal thread of front end, the copper core 6 back welding of the groove insertion wire 7 of rear end get final product, certainly not the tubular nut in garden that does not also have afterbody of trough of belt also can, the method that need not weld, the perforation of copper core is fixing also can.Make the rubber of rubber seal insulating barrier 4 and select acrylonitrile-butadiene rubber for use, before the use, on the outer wall of the end of stainless steel tube 2, coat commercially available Kai Muluoke 205 adhesive 9 earlier, on the overcoat of the connection end of lead 7, coat commercially available Kai Muluoke 238 adhesive 8.Again with the acrylonitrile-butadiene rubber band with stainless steel tube 2 connect the lead copper core 6 of ends, the part eduction rod 3 that exposes, connector 5, exposed parts, the overcoat that lead 7 connects ends was wrapped with, and places mould, 130-160 ℃ of temperature conditions dip molds 2-3 minutes.As for the whole manufacture craft of metal electric heating element, as the wrapping wire that cuts material, cleaning straightening, heating wire, the string pipe of stainless steel tube, to add modified magnesium powder, test, the draw, oven dry, silicone oil sealing or the like all be routine techniques, be that the one's own profession those of ordinary skill is known, do not give unnecessary details for this reason.The used raw material of the utility model all are commercially available.
The utility model have compared to existing technology be connected firmly, electric conductivity is good The advantages such as good, spoilage is low, are led at acrylonitrile-butadiene rubber sealed insulation layer and stainless steel Increase the Kai Muluoke adhesive layer between the line overcoat, strengthened pull-out capacity, waterproof Insulating properties is especially good, adapts to low temperature and high temperature variation requirement greatly under the defrosting environment.
