Abstract
The invention relates to the technology of cable shield formation, in particular to a die sleeve applicable to a die for the formation of a self-supporting coaxial cable sheath. The die sleeve provided by the invention is realized through the following technical scheme: the die sleeve applicable to the die for the formation of the self-supporting coaxial cable sheath is characterized in that a steel suspension wire sheath outlet, a cable semi-finished product sheath outlet and a connecting clearance for enabling the steel suspension wire sheath outlet to be communicated with the cable semi-finished product sheath outlet are formed in one end wall of the die sleeve; the connecting clearance closes up in the direction from the steel suspension wire sheath outlet to the cable semi-finished product sheath outlet. The cable sheath uses the die sleeve provided by the invention, when a steel suspension wire is separated from the cable, the cable sheath is less susceptible to damage. Therefore, the die sleeve facilitates the guarantee of the electrical performance, the corrosion resistance and waterproofness of a cable.
Description
Technical field
The present invention relates to cable cover(ing) forming technique, particularly a kind of die sleeve being applicable to self-bearing type coaxial cable cover(ing) molding die.
Background technology
Self-bearing type coaxial cable cover(ing) molding die of the prior art, if publication number is a kind of mold used for producing self-supporting type moisture-resistant cable sheath disclosed in the patent application of CN101630547A, comprise core rod, die sleeve, described core rod and described die sleeve matched in clearance, be provided with cable messenger through hole, cable semi-finished product through hole in described core rod, described cable messenger through hole and described cable semi-finished product through hole are spaced from each other; The die sleeve of this kind of mould is generally rectangle for being communicated with the joint gap that cable messenger sheath exports and cable semi-finished product sheath exports; After making product shaping, when cable messenger is separated with cable, the sheath of fragile cable, thus affect the electric property of cable and anticorrosion, waterproof ability.
Summary of the invention
The object of this invention is to provide a kind of die sleeve being applicable to self-bearing type coaxial cable cover(ing) molding die, use this die sleeve cable cover(ing), at separation of steel messenger wire and cable, the sheath of cable is not easily damaged, thus is conducive to ensureing the electric property of cable and anticorrosion, waterproof ability.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of die sleeve being applicable to self-bearing type coaxial cable cover(ing) molding die, and this die sleeve one end wall has the outlet of cable messenger sheath, the outlet of cable semi-finished product sheath, makes the outlet of described cable messenger sheath export with described cable semi-finished product sheath the joint gap be connected; Described joint gap is exported to described cable semi-finished product sheath Way out in drawing shape in along described cable messenger sheath.
As preferably of the present invention, the junction between described joint gap and described cable messenger sheath export is fillet or chamfering.
As preferably of the present invention, the junction between described joint gap and cable semi-finished product sheath export is fillet or chamfering.
As preferably of the present invention, the junction between described joint gap and described cable messenger sheath export is fillet, and this radius of corner is 0.45-0.8mm.
As preferably of the present invention, the junction between described joint gap and cable semi-finished product sheath export is fillet, and this radius of corner is 0.2-0.3mm.
As preferably of the present invention, this die sleeve other end caves inward formation running-on.
As preferably of the present invention, described running-on is taper.
In sum, the present invention has following beneficial effect: structure of the present invention is simple, easy to implement, and be draw shape in because joint gap is exported to cable semi-finished product sheath Way out along cable messenger sheath, make at separation of steel messenger wire and cable, the sheath of cable is not easily damaged, thus is conducive to ensureing the electric property of cable and anticorrosion, waterproof ability; More due to the setting of above-mentioned fillet or chamfering, after cable messenger is separated with cable, sheaths separate place can not become thin due to tearing action, thus avoided the impact on sheath physical property, was conducive to the electric property ensureing cable.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram;
Fig. 2 is cable messenger sheath outlet in embodiment, cable semi-finished product sheath exports and the structural representation of joint gap;
Fig. 3 is embodiment cutaway view.
In figure, 11, the outlet of cable messenger sheath, 12, the outlet of cable semi-finished product sheath, 13, joint gap, 14, running-on.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present invention.
Embodiment: a kind of die sleeve being applicable to self-bearing type coaxial cable cover(ing) molding die, as Figure 1-3, die sleeve one end wall has cable messenger sheath outlet 11, cable semi-finished product sheath outlet 12, makes cable messenger sheath outlet 11 export 12 joint gaps be connected 13 with cable semi-finished product sheath; Joint gap 13 exports 12 directions in drawing shape in along cable messenger sheath outlet 11 to cable semi-finished product sheath.
Joint gap 13 and the cable messenger sheath junction exported between 11 are fillet, and this radius of corner is 0.45-0.8mm, is generally 0.65mm; Joint gap 13 and the cable semi-finished product sheath junction exported between 12 are fillet; This radius of corner is 0.2-0.3mm, is generally 0.25mm.
The die sleeve other end caves inward and forms running-on 14; Running-on 14 is in taper.
