Abstract
The utility model provides a copper or aluminum wire structure with sealed protective adapter. The structure is composed of an aluminum wire, an aluminum wire or a copper wire, an adhesive heat-shrinkable sleeve and a pressed terminal or a solder connection. The aluminum wire or the copper wire is arranged below the aluminum wire. The pressed terminal or the solder connection is adopted in the positions of the adapters on the ends of the aluminum wire and the aluminum wire or copper wire, and the positions of the adapters are sealed by packaging adhesive, epoxy resin or other fillers, and are sleeved by the adhesive heat-shrinkable sleeve with one end being sealed. The copper or aluminum wire structure ensures good contact of the adapter, isolates air and water, prevents the adapter oxidization caused by the primary cell reaction between copper and aluminum, and prolongs the service life of electrical appliances.
Description
Technical field:
The utility model relates to the structure of a kind of copper, aluminum steel band sealing protection joint.
Background technology:
Because the copper valency sharp rises, the copper enamelled wire has accounted for about 50% of medium and small motor material total cost, and motor manufacturing enterprise adopts enamel insulated aluminium wire as the motor windings material for reducing cost.But aluminum steel is connected with aluminum steel or the deficiency of aluminum steel and copper cash interconnection technique and process aspect, and the easily oxidation of aluminium surface directly has influence on quality, reliability and the useful life of joint; When copper, aluminium conductor directly connect, the contact-making surface of these two kinds of metals very easily forms electrolyte under the effect of water in air branch, carbon dioxide and other impurity, thereby what form is that negative pole, copper are anodal primary cell with aluminium, make aluminium produce couple corrosion, cause the contact resistance of copper, aluminium junction to increase, the increase of contact resistance, the temperature that will cause in service raises, corrosion oxidation will aggravate under the high temperature, produce vicious circle, quality of connection is further worsened, cause the contact point temperature too high even accident such as can smolder, burn at last.
Summary of the invention:
The purpose of this utility model is exactly the structure that a kind of copper, aluminum steel band sealing protection joint will be provided, and it can overcome well, and above aluminum steel is connected with aluminum steel or aluminum steel is connected existing problem with copper cash.The purpose of this utility model is to realize like this, the structure of a kind of copper, aluminum steel band sealing protection joint, by aluminium matter line, aluminium matter line or copper line, band glue heat-shrinkable T bush, press-fit terminal or scolding tin and connect institute and form, it is characterized in that: an aluminium matter line or copper line are set below aluminium matter line, at an end connector place of aluminium matter line and aluminium matter line or copper line with press-fiting terminal or scolding tin is connected, encapsulating compound, epoxy resin or other packing seal are set in its joint, and put the band glue heat-shrinkable T bush of end sealing.The utility model can guarantee that the joint contact is good, and secluding air and water stop copper aluminium to form the joint oxidation that the primary cell reaction is brought, the useful life of having improved motor.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. aluminium matter line 2. press-fits terminal or scolding tin and connects, 3. encapsulating compound, epoxy resin or other filler, 4. band glue heat-shrinkable T bush, 5. aluminium matter line or copper line.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, the structure of a kind of copper of the utility model, aluminum steel band sealing protection joint, by aluminium matter line 1, aluminium matter line or copper line 5, band glue heat-shrinkable T bush 4, press-fit terminal or scolding tin and connect 2 and form, it is characterized in that: an aluminium matter line or copper line 5 are set below aluminium matter line 1, at an end connector place of aluminium matter line 1 and aluminium matter line or copper line 5 with press-fiting terminal or scolding tin is connected 2, encapsulating compound, epoxy resin or 3 sealings of other filler are set in its joint, and put the band glue heat-shrinkable T bush 4 of end sealing.During concrete enforcement, after the end connector welding or crimping of copper cash, aluminum steel or aluminium, aluminum steel, seal with encapsulating compound in the joint, and put the band glue heat-shrinkable T bush of end sealing, the heating back forms seal protection in the joint.Another kind of embodiment is that copper cash, aluminum steel or aluminium, aluminum steel one end connector place are carried out the injection moulding sealing or carry out frit seal with easy welded joint, and good to guarantee the joint contact, secluding air and water stop copper aluminium to form the joint oxidation that the primary cell reaction is brought.Therefore prolonged the useful life of motor greatly.
