Abstract
The utility model discloses a point type responser data transmission cable, which comprises a plurality of conducting bodies covered with insulating layers, wherein the conducting bodies covered with insulating layers are mutually twisted to form a cable core by using a pressure resistant core as the center, the center of the pressure resistant core is provided with air holes, the pressure resistant core is pasted with the outer wall of the insulating layer, two twisted current discharge wires are arranged outside the cable core, and a shielding layer, an inner lining layer, an armoring layer and a sheath layer are sequentially arranged outside the cable core and the current discharge wires. The point type responser data transmission cable has the advantages that the structure is simple, the design is reasonable, the pressure resistant core is arranged in the center of the cable core of the cable, the air holes are arranged in the center of the pressure resistant core, the conducting body damage caused by the external pressure can be effectively reduced, the buffer effect is obvious, and simultaneously, the structure compactness and the tensile strength of the cable are improved.
Description
Technical field:
The utility model relates to the dot-mode transponder technical field, relates in particular to a kind of dot-mode transponder data transmission cable.
Background technology:
The utility model is mainly used in being connected between dot-mode transponder and the LEU electronic power supply, plays the transmission of transfer encoding, message data information and electric energy, can use in railway electrification and non-electrified different sections.The general environment for use temperature-40 of cable ℃ ~+60 ℃, the long-term use working temperature of cable conductor is no more than 70 ℃.
There is certain deficiency in original design, and the structural compactness of cable is relatively poor, and cable can receive extraneous extruding in actual working environment, and for causing breaking of cable insulation in the extrusion process, the damage conductor influences the normal information transmission of cable work.
The utility model content:
In order to remedy the deficiency of prior art, the purpose of the utility model provides a kind of dot-mode transponder data transmission cable, and the structural design advantages of simple has been alleviated the damage of outer bound pair cable.
The technical scheme of the utility model is following:
Dot-mode transponder data transmission cable; The conductor that comprises several wrap insulate layers; It is characterized in that: the conductor of wrap insulate layer is the mutual stranded formation cable core in center with the resistance to compression core, and resistance to compression core center is provided with pore, and resistance to compression core and insulating barrier outer wall fit; Cable core is provided with the earial drainage line of two pair twists outward, and cable core and earial drainage line are provided with screen, inner covering, armour, restrictive coating outward successively.
Described dot-mode transponder data transmission cable is characterized in that: it is polyolefin that described insulating barrier and protective layer adopt material.
Described dot-mode transponder data transmission cable is characterized in that: described screen adopts the wrapped formation of steel band, and the wrapped rate of putting up is not less than 55%.
The utility model has the advantages that:
The utility model is simple in structure, and is reasonable in design, is provided with the resistance to compression core at the cable core center of cable; Resistance to compression core center is provided with pore; Can effectively reduce the damage of ambient pressure to conductor, cushioning effect is obvious, has improved the structural compactness and the tensile strength of cable simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
