Abstract

The utility model relates to a cable sealing head cap capable of one-way exhausting, which comprises a sealing head cap, wherein a one-way valve is arranged in the middle of the sealing cap; the one-way valve is ventilated from inside to outside; and the gap between the one-way valve and the sealing head is sealed by sealant. The cable sealing head cap is convenient in material obtaining, easy in operation and low in cost, and when pressure in the cable is over high, the air is exhausted, while water outside the cable is prevented from entering the cable from the passage in virtue of the one-way valve, thereby ensuring the quality safety of the cable in storage.

Description

A kind of cable end socket cap with unidirectional exhaust

Technical field

The utility model relates to cable end socket field, particularly relates to a kind of cable end socket cap with unidirectional exhaust.

Background technology

Because medium and high voltage cable is behind the finished product end socket, a certain amount of gas also can be overflowed in cable insulation inside, and gas produces bigger pressure in the inner meeting of the cable of sealing, thereby can make cable cover(ing) lax, even produces the sheath bulge.After cable is installed, may cause between electric cable accessories and cable insulation to have the gap, produce partial discharge, have a strong impact on product quality.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of cable end socket cap with unidirectional exhaust, and " degassing " time that reduces in the cable production process shortens the production cycle.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of cable end socket cap with unidirectional exhaust is provided, comprises the end socket cap, be provided with unidirectional valve in the middle of the described end socket cap; The ventilation direction of described unidirectional valve is for from inside to outside.

Gap between described unidirectional valve and the end socket cap is sealed by fluid sealant.

Beneficial effect

Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model is drawn materials conveniently, processing ease, cost is low, gas can be discharged when the cable internal pressure was higher, and outside moisture has guaranteed the quality safety when cable is stored because the effect of unidirectional valve can not enter into cable inside from this channel.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Execution mode of the present utility model relates to a kind of cable end socket cap with unidirectional exhaust, as shown in Figure 1, comprises end socket cap 1, is provided with unidirectional valve 2 in the middle of the described end socket cap 1; The ventilation direction of described unidirectional valve 2 is for from inside to outside.Gap between described unidirectional valve 2 and the end socket cap 1 is by fluid sealant 3 sealings.

Using method of the present utility model is as follows: with the end of cable 4 inner termination cut flat after, the cable end socket cap 1(that puts band unidirectional valve 2 is the utility model), wherein, the ventilation direction of unidirectional valve 2 is for from inside to outside, adding heat-sealing head cap 1 with blowtorch makes its contraction seal cable 4, use the gap of fluid sealant 3 leakproof one-way valves 2 and end socket cap 1 centre again, finish end socket.Gas can be discharged when cable 4 internal pressures are higher, and outside moisture has guaranteed the safety of cable 4 because the effect of unidirectional valve 2 can not enter into cable 4 inside from this channel." degassing " time that suitably reduces in the cable production process by the utility model has shortened the production cycle.

Claims

1. the cable end socket cap with unidirectional exhaust comprises end socket cap (1), it is characterized in that, is provided with unidirectional valve (2) in the middle of the described end socket cap (1); The ventilation direction of described unidirectional valve (2) is for from inside to outside.

2. the cable end socket cap with unidirectional exhaust according to claim 1 is characterized in that the gap between described unidirectional valve (2) and the end socket cap (1) is sealed by fluid sealant (3).
