Abstract
The utility model discloses an inner gas circuit disconnecting structure for a wire or a cable. The inner gas circuit disconnecting structure includes a conducting core with an insulating protective sleeve, and an insulator for disconnecting the gas circuit in the wire or the cable is arranged at an end part of the insulating protective sleeve. The insulator is tightly adhered with the conducting core at the end of the insulating protective sleeve and covers and seals the end part of the insulating protective sleeve. The utility model aims to provide the inner gas circuit disconnecting structure for the wire or the cable, which can prevent gas or liquid transmission in the wire or the cable and further prolong the service lives of contacts connected the wire or the cable and electrical equipment.
Description
[technical field]
The utility model relates to a kind of electric wire, cable, furtherly be gas circuit disrupted configuration in a kind of electric wire or the cable.
[background technology]
At present, the electric wire of domestic production, cable are generally metal and lead core outsourcing one deck insulating sleeve, this lead is in the outdoor application process, when there is pressure reduction in the electric wire two ends, airborne gas or liquid can both gas circuit be delivered to the lead other end from lead one end between core and the insulating sleeve contact-making surface by leading, thus the decompression of causing; Multi cord also has the pressure reduction transmission between multi cord insulating sleeve and the outermost layer protective layer in this way, thus the decompression of causing.During decompression, moist gas and rainwater will be by input, output connector junctions, through leading core and leading that path enters electrical equipment or contact head between the core insulation sheath, cause electrical equipment or contact head to damage, and influence the useful life of electrical equipment or contact head.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, provides to prevent that gas or liquid from transmitting in electric wire, cable the gas circuit disrupted configuration in a kind of electric wire in contact or electrical equipment useful life or the cable thereby prolongation is connected with electric wire, cable.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
Gas circuit disrupted configuration in a kind of electric wire or the cable includes the core of leading of tape insulation sheath, it is characterized in that described insulating sleeve end is provided with the insulation that gas circuit blocking-up in the line can be opened.
Gas circuit disrupted configuration in aforesaid a kind of electric wire or the cable is characterized in that described insulation and described insulating sleeve end place lead that core closely bonds and described insulating sleeve end is covered, seals.
Gas circuit disrupted configuration in aforesaid a kind of electric wire or the cable is characterized in that the described core of leading has many, and described insulating sleeve has a plurality of, and each insulating sleeve correspondence is sleeved on respectively to be led outside the core, and the insulation at each insulating sleeve end place is connected as a single entity.
Gas circuit disrupted configuration in aforesaid a kind of electric wire or the cable is characterized in that described insulation is sealing viscose glue or garment bag.
The beneficial effects of the utility model are: the insulating sleeve end is provided with insulation, this insulation and insulating sleeve end lead that core closely bonds and with the insulating sleeve end cover, sealing, make insulating sleeve and lead and be sealing state between the core, leading core and leading between the core outer insulation jacket no longer is a communication passage, in the time of can preventing like this that negative pressure from producing gas or liquid transmit in electric wire, cable, thereby have solved contact that the waterproof problem prolongation is connected with electric wire, cable or electrical equipment useful life.

[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in the figure, the utility model is a gas circuit disrupted configuration in a kind of electric wire or the cable, and what include tape insulation sheath 2 leads core 1, and this leads core 1 can be one or more.Described insulating sleeve 2 ends are provided with the insulation 3 that gas circuit blocking-up in the line can be opened, insulation 3 can be sealing viscose glue or garment bag, in the utility model, described insulation 3 and described insulating sleeve 2 end places lead that core 1 closely bonds and with described insulating sleeve 2 ends cover, sealing, gas or liquid transmit in electric wire, cable in the time of can preventing like this that negative pressure from producing, thus the contact that prolongation is connected with electric wire, cable or electrical equipment useful life.
See Fig. 4, this is that the utility model is applied on the LED charactron exterior decoration lamp, and LED charactron exterior decoration lamp is when work, because the lamp pearl is luminous, heating, causes the airtight interior gas of PC pipe to expand, and air pressure increases; When running into weather and rain, PC tube-surface greenhouse cooling, at this moment contraction of gas in the PC pipe produces negative pressure.Because the effect of negative pressure, moist gas and rainwater will be by input, output connector junctions, lead core 1 and lead that path enters in the PC pipe between core 1 outer insulation jacket 2, cause the damage of LED charactron.And the utility model carries out encapsulation process at insulating sleeve 2 end places by insulation 3 exactly, make insulating sleeve 2 and lead between the core 1 and be sealing state, when the PC pipe has negative pressure, air-flow can't pass down along leading core 1 and leading between core 1 outer insulation jacket 2, promptly cut off path between the input of PC pipe and power supply and signal, the output connector joint, avoided the negative pressure in the PC pipe to be transmitted on the connector, thereby preferably resolve LED charactron exterior decoration lamp waterproof problem, improved the LED number in pipe exterior decoration lamp useful life.
As Fig. 1, Fig. 2, shown in Figure 3, when leading core 1 when having many, insulating sleeve 2 also has a plurality of, and each insulating sleeve 2 correspondence is sleeved on respectively to be led outside the core 1, and the insulation 3 at each insulating sleeve 2 end place is connected as a single entity.During actual the use, generally, its objective is multi cord is become a strand, between tining place and insulating sleeve 2 end places, carry out viscose glue more then, treat to use after glue solidifies fully at insulating sleeve 2 end place tinings.
Fig. 1 is embodiment 1 of the present utility model, and leading core 1 is two, and insulating sleeve 2 is two.
Fig. 2, Fig. 3, Fig. 4 are embodiment 2 of the present utility model, and leading core 1 is five, and insulating sleeve 2 is five.
