Description
Technical field
It the utility model is related to technical field of electricity, and in particular to a kind of waterproof leakproof electrical connecting wire.
Background technology
Wire connection is a basic working procedure of Electrician Operation, an and highly important process.The matter of wire connection
Can amount is directly connected to whole circuit safely and reliably longtime running.To wire connection basic demand be：Being connected firmly can
Lean on, connection resistance is small, high mechanical strength, corrosion-resistant resistance to oxidation, electrical insulation properties are good.In order to be attached, connecting position of wires
Insulating barrier be removed.After the completion of wire connection, it is necessary to the position being removed to all insulating barriers carries out insulation processing, with
Recover the insulating properties of wire, the dielectric strength after recovery should be not less than the original dielectric strength of wire.
At present, the insulation processing of connecting position of wires is typically to use insulating tape or heat-shrink tube in the joint of connecting wire
Wrapped up or worn plastic insulation cap (set).However, parcel and heat-shrink tube progress pyrocondensation parcel are wound using insulating tape
Or when wearing plastic insulation cap (set), insulating tape, heat-shrink tube or the wire for wearing plastic insulation cap (set) and joint both ends be present
Insulating barrier is bonded the problem of defective tightness, and the steam in use environment inevitably enters at the slight gap of joint both sides
Enter to exposed joint, the oxidation so that joint makes moist, cause connecting wire connection resistance to become big, caloric value increase, sternly
Even trigger security incident during weight；Furthermore insulating tape, heat-shrink tube or plastic insulation cap (set) are also deposited and after a long time use can
There is the problem of aging comes off and released.In addition, when insulating tape and heat-shrink tube or plastic insulation cap (set) are combined with joint, only
It can be completed using winding by hand and manual heating, difficulty establishes performance assessment criteria, such insulating tape and heat-shrink tube or plastic insulation
The bond strength of cap (set) and joint and its joint both ends insulating barrier is difficult to strictly control, and the difference of bond strength can cause again to be connect
Head resistance sizes are distinct, make the process standard of whole connecting wire uncontrollable, can not be adapted to normalizing operation, from
And product quality is caused to bring uncertainty.
Utility model content
To be solved in the utility model is that the insulation processing generally use insulating tape of connecting position of wires carries out swathing bag
Bundle or heat-shrink tube are wrapped up or worn the deficiency present in plastic insulation cap (set), there is provided a kind of waterproof leakproof electrical connecting wire.
To solve the above problems, the utility model is achieved through the following technical solutions：
A kind of waterproof leakproof electrical connecting wire, the wire are provided with exhausted with the exposed joint of a core, the joint
Edge colloid, the insulation colloid coat the outside of whole joint completely, and the colloid wire insulation with joint both ends respectively that insulate
Layer combines together；The gap location of core is penetrated on the inside of insulation colloid.
In such scheme, the length of the insulation colloid is longer than the length of joint.
In such scheme, the section shape of the insulation colloid is identical with the section shape of wire.
In such scheme, the insulation colloid is the implastic resin of normal temperature or PUR.
In such scheme, the fusing point or softening point of the insulation colloid are more than 80 DEG C.
In such scheme, the joint is the pressure joint of metal sleeve parcel.
Compared with prior art, the utility model has following features：
1. insulating cement body can be close with the joint core exposed section of connecting wire and the wire insulation at joint both ends
With reference to so as to effectively avoid water in use environment or steam from entering exposed joint, preventing connecting wire joint
The caused terminal resistance of oxidation becomes the problem of big, and joint is immersed in water and drawn because water enters exposed joint
The problem of playing electric leakage；
2nd, insulation colloid can be integrally formed using pressing mold mode, by controlling sizing material amount, the temperature of pressing mold, pressure etc. to join
Number realizes normalizing operation, so not only enables the adhesion of insulation colloid and joint strict controllable, and then the company of ensure that
The unification of the connection resistance size of wire is connect, and more conducively mass standardized production is processed；
3rd, connecting wire is obtained using crimping mode, and this connected mode is due to conducting wire end docking length, metal sleeve
Type selecting, the pressure of line ball can accomplish to completely unify, standardization level is higher, thus is more suitable for normalizing operation and production.

Fig. 2 is the front view of another waterproof leakproof electrical connecting wire.
Label in figure：1st, insulating barrier；2nd, core；3rd, joint；3-1, metal sleeve；4th, insulate colloid.
Embodiment：
A kind of waterproof leakproof electrical connecting wire, the wire is mainly by core 2 and 1 group of insulating barrier being wrapped on the outside of core 2
Into.Because the wire is connecting wire, therefore the stage casing of the wire is with the exposed joint 3 of a core 2.Connecting wire connects
First 3 can with as shown in figure 1, for 2 wires core 2 directly by by hand winding 2 wires link together, thus obtain
Obtain connecting wire.This connected mode is simple and easy, but the problem of fastness of joint 3 and unmanageable resistance sizes be present.Therefore,
Standardization control is difficult in view of the joint 3 of artificial winding core 2, the joint 3 of connecting wire can also be as shown in Fig. 2 first
Allow the both ends of core 2 of 2 wires to be directly through in metal sleeve 3-1, after metal sleeve 3-1 2 compressed by Crimping Pliers
Wire links together, and is derived from connecting wire.This connected mode is due to conducting wire end docking length, metal sleeve 3-1
Type selecting, the pressure of line ball can accomplish to completely unify, standardization level is higher, thus is more suitable for normalizing operation and production.
Selected metal sleeve 3-1 material is consistent with the material of core 2, and when such as core 2 being copper, metal sleeve 3-1 selects copper
Sleeve pipe processed；When such as core 2 being aluminum, metal sleeve 3-1 selects aluminium casings.
In order to which butt joint 3 carries out insulation processing, to recover the insulating properties of wire, insulation colloid is provided with the joint 3
4.The insulation colloid 4 coats the outside of whole joint 3 completely, and the wire insulation with the both ends of joint 3 respectively of colloid 4 that insulate
1 combines together；The gap location that the inner side of insulation colloid 4 is penetrated between core 2.
Insulation colloid 4 is made of the implastic resin of normal temperature or PUR.In the utility model, insulation colloid 4
Fusing point or softening point are more than 80 DEG C.Also just say, insulation colloid 4 is in liquid on the fusing point or softening point, to insulate
Colloid 4 preferably can be processed and shape in processing；And the colloid 4 that insulate is solid-state under the fusing point or softening point, make
The colloid 4 that must insulate is under stable form when in use.
The length of insulation colloid 4 can be exactly equal to the length of joint 3, and the both ends for the colloid 4 that now insulate are just and wire
The side edge of insulating barrier 1.In order to ensure the dielectric strength and water proofing property of insulation colloid 4, the length of insulation colloid 4, which is slightly longer than, to be connect
First 3 length, the both ends for the colloid 4 that now insulate can be coated on outside the insulating barrier 1 of wire.The section shape of insulation colloid 4 is with leading
The section shape of line is identical.When such as wire being round conductor, the section shape for the colloid 4 that insulate also is circle；If wire is flat bar
During shape wire, the section shape of insulation colloid 4 is also flat bar.
