Description

A kind of waterproof cable connector

Technical field

The invention of this reality is related to a kind of water-proof function cable connector for preventing moisture, if more particularly to it is a kind of cancel it is separable Even after component, it may have the separable connector of water-proof function.

Background technique

Such as electric system power generation is transmitted electricity, the network system in distribution, is required through overhead line or cable connection ability It realizes, the terminal of intermediate connection, cable and power equipment between overhead line or cable connects, and is required to pass through cable connector To realize.

If, in the junction of existing cable connector, moisture can be along line under the specific condition of burst big flood immersion The clearance channel of core enters cable connector, and penetrates further into inside separable connector, causes short circuit or leaky, thus Occurrence of large-area grid power blackout accident not only influences high-intensitive region economic activities, or even can induce political, military sensitive living It a possibility that dynamic, must be examined in electric power project engineering.

Currently, in cable accessory installation, either cable core or cable connector dampness or water inlet connects in cable Its mode handled is to vacuumize under the premise of the also not charged operation of head, this method can only reduce the moisture inside cable core, Vacuum method can thermodynamically be determined except not clean moisture, moisture is in the presence of the security risk for being still power grid；If cable connects The operational process water inlet of head after mounting, equally exists the high probability for causing short circuit or leaky, cable connector water inlet pair It is huge technological challenge for cable accessory industry.Therefore, the technological approaches of power grid security is promoted, one of key, Key factor is how to prevent the problem of intaking with quantitative judge cable connector.

Although China Patent Publication No. CN 206541640U (a kind of separable cable of water proof type prefabricated) recognizes cable The seriousness of connector water inlet, the patent have done reinforcing water-proofing treatment to the cable branch structure of separable connector body exterior, Its technical solution is the setting PVC, waterproof roll, water-absorbing resin, interior anti-corrosion layer material between insulating layer and oversheath, attempts to mention The function of high waterproof, but the program, which can only prevent outside water, enters cable branch interface, without having in separable connector Portion's water stopping function.

Therefore, it is necessary to a kind of cable connector new construction for ending moisture and entering inside separable connector be designed, to mention The security reliability of high operation of power networks reduces or even prevents to cause great power grid accident because of burst immersion or rainy season environment.

Summary of the invention

The purpose of this utility model is to provide a kind of cable connector new construction with water-proof function is being happened suddenly with improving The system reliability that high-voltage fence is run under immersion or rainy season installation environment.

In order to achieve the above object, a kind of waterproof cable connector of the utility model, comprising: separable connector, is prevented terminal Water assembly and cable；Be provided with mounting hole and spliced eye on the separable connector, and mounting hole and spliced eye it is orthogonal and Connection；On the terminal be furnished with aluminium hydraulic pressed connecting pipe, and aluminium hydraulic pressed connecting pipe be accommodated in in mounting hole and spliced eye；Core in the cable Or conductor is connected in a manner of crimping with aluminium hydraulic pressed connecting pipe；Flexible seal layer and prestressing force clad are provided on the water repellent component, it should Flexible seal layer also overlaps environmental sealing, prestressing force packet by the core environmental sealing of cable socket, by aluminium hydraulic pressed connecting pipe, insulating layer respectively Coating is wrapped in the appearance of flexible seal layer.

Further, spliced eye positioned inside cable adaptor, cable adaptor respectively with mounting hole inner boundary And insulating layer outer boundary interference fit.

Further, the terminal has connection sheet and aluminium hydraulic pressed connecting pipe, and the connection sheet connects conducting with aluminium hydraulic pressed connecting pipe, and crimps Pipe is accommodated in the spliced eye vertical with mounting hole.

Further, the flexible seal layer is the elastomer that secant modulus is less than or equal to 173MPa；The prestressing force Clad is semi-rigid crosslinking rubber-plastics material of the secant modulus within the scope of 173~960MPa, and it is lasting to apply for flexible seal layer Pretightning force.Moisture is prevented to enter inside connector from the core gap of cable by water repellent component, prevents moisture on-line core and pressure Adapter tube junction and the external world are connected and cause cable connector and environment short circuit or electric leakage accident.

Further, the cable is commercial standard cable, and structure includes core and insulating layer from inside to outside.

Further, and an entirety can be made using identical material in flexible seal layer and prestressing force clad.

Preferably, the separable connector and cable adaptor, the connection sheet of terminal and aluminium hydraulic pressed connecting pipe select commercial standard Part.

Preferably, the flexible seal layer is cold-shrinkage silicone rubber tube, elastic emulsion pipe, the sealing of one-component curable polyurethane Any one of cream, two-component curable polyurethane sealing compound, liquid silicone rubber.

Preferably, the prestressing force clad includes organic silicon rubber cold shrink tube, polyurethane cold shrink tube, chemical crosslinking are poly- Any one of alkene heat-shrink tube, irradiated crosslinked polyalkene heat-shrink tube.

A kind of this waterproof cable connector invented in fact, advantageous effects are:

1. having completely cut off moisture, moisture cannot penetrate into core gap and separable connector cavity；

2. improving electric network reliability, a possibility that such power grid node causes power outage because of water inlet is prevented；

3. it is versatile, still there is water-proof function when separable connector is default.
