Abstract

The utility model relates to a waterproof joint of an electric hot plate. The technical problems to be solved in the utility model are that the waterproof joint provided by the utility model should have the characteristics of excellent joint strength, no heat generation, excellent waterproof property, and safe usage on the premise of realizing the basic function of electrical connection. The technical scheme is that the waterproof joint of the electric hot plate includes a power supply line, and a connecting line led out from a carbon crystallite heating membrane which is electrically connected with the power supply line; a joint terminal of the connecting line forms a tightly wrapped spiral coil after winding a plurality of loops around a bare conducting part of the power supply line. The waterproof joint is characterized in that the periphery of the spiral coil is coated by a metal sleeve which is clamped into deformation, and the metal sleeve exerts the clamping pressure on the spiral coil; and a plastic sleeve which becomes deformed after the thermal shrinkage is tightly coated on the joint part of the connecting line and the power supply line, and entirely covers the metal sleeve. The gap between an inner wall of the plastic sleeve and the joint part is filled with a waterproof hot melt adhesive, and the metal sleeve is an aluminium sleeve.

Description

A kind of water joint of electric hot plate
Technical field
The utility model relates to a kind of electrical connector, especially the water joint of electric hot plate.
Background technology
As the heater element of a new generation, carbon trichite hotting mask is used widely in recent years.The electric conversion rate of carbon trichite hotting mask can be converted to by carbon trichite hotting mask up to the input of 98%, 100% electric energy and surpass 60% conduction heat energy and surpass 30% infrared energy.With the carbon trichite hot plate that carbon trichite hotting mask is made, be widely used as heating floor, heating skirt wallboard, heating platen etc.
Disposing a plurality of carbon trichite hotting masks in the common carbon trichite hot plate, these carbon trichite hotting masks need adopt parallel connection method energized line.The mode of conventional energized line is: earlier the bare exposed conductor part coiling some circles of the wiring of drawing on the carbon trichite hotting mask around power line, coat with adhesive plaster then.The defective of this connection is: 1, along with the increase of service time, blank area is loosening easily to cause the heating phenomenon after causing loose contact and then causing resistance to increase, when serious even fused wire.2, joint area does not have water-proof function; Cause electric leakage easily in moist occasion use, become unsafe factor.
The utility model content
The purpose of this utility model is the deficiency that will overcome the above-mentioned background technology, a kind of water joint of electric hot plate is provided, this water joint should guarantee under the basic function prerequisite that realizes being electrically connected, have bonding strength good, can not generate heat, characteristics that water resistance is good and safe in utilization.
The technical solution adopted in the utility model is: a kind of water joint of electric hot plate, the wiring of drawing in the carbon trichite hotting mask that comprises power line and be electrically connected with power line, the tip side of this wiring forms the spiral coil that closely holds around the some circles of the bare exposed conductor part coiling of power line back; The periphery that it is characterized in that described spiral coil coats and is subjected to the pincers pressure that this metal sleeve applies by a metal sleeve that clamps compressive strain, and other has the plastic bushing after the pyrocondensation distortion closely to be coated on the connecting portion of described wiring and power line and is covered with described metal tube fully.
Be filled with the waterproof PUR in the inwall of described plastic bushing and the slit of described connecting portion.
Described metal tube is an aluminium matter sleeve pipe.
The beneficial effects of the utility model are: because aluminium matter sleeve pipe tightly coats the spiral coil that the wiring tip side in interlock after adopting the compressive strain of Crimping Pliers pincers, guaranteed that tip side can not unclamp, not only improved bonding strength, also solved the heating phenomenon of existing tip side.And the inwall that is adopted has the plastic bushing of waterproof PUR, closely is coated on the connecting portion of wiring and power line after the pyrocondensation distortion; All block all slits again after the waterproof PUR cooling of melted by heat, guaranteed that extraneous aqueous vapor can not enter in the plastic bushing, and then guaranteed safe in utilization.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Fig. 2 is the A portion structure for amplifying schematic diagram among Fig. 1.
Embodiment
As shown in the figure, the water joint of this electric hot plate, comprise power line 1 and from carbon trichite hotting mask, draw after be connected wiring 2 on the power line; The tip side 2-1 of described wiring (removing metallic conductor exposed behind the sheath) is the some circles of circumferential coiling of (after removing sheath exposed metallic conductor) at the bare exposed conductor 1-1 position of power line, form closely around spiral coil; The metal sleeve 3 of one pincers compressive strain (adopt the Crimping Pliers pincers to press usually and make its distortion) is coated on the peripheral of described spiral coil and described spiral coil is applied pincers pressure, other has the plastic bushing 5 (inwall of plastic bushing scribbles the waterproof PUR in advance) after the pyrocondensation distortion closely to be coated on the connecting portion of described wiring and power line and is covered with described metal tube fully, stopping up all slits of connecting portion after the waterproof PUR cooling after the melted by heat, and then guaranteeing that steam can't enter plastic bushing inside.
Described plastic bushing and metal tube are all outsourcings of aluminium matter sleeve pipe.
Manufacturing process of the present utility model is: respectively the joint area of wiring and power line is removed sheath earlier, then the tip side helical form of wiring is looped around on the power line; Then after wearing an aluminium matter sleeve pipe, the junction makes it to be out of shape the tip side that wiring in interlock with Crimping Pliers pincers pressure; Wear at last a plastic bushing 5 that has a waterproof PUR at the peripheral place of aluminium matter sleeve pipe, heat then (can adopt hair dryer to heat) can make plastic bushing produce pyrocondensation and make the fusing of waterproof PUR to stop up all slits.
