The jumper wire comprises a jumper wire body, the jumper wire body comprises a fiber core, a steel armored layer, a fibrous layer and an oversheath layer are successively sleeved outside the fiber core, an inserting core is arranged on the end part of the jumper wire body, the fiber core and the steel armored layer of the end part of the jumper wire body are inserted into a tail handle of the inserting core, and the fibrous layer of the end part of the jumper wire body is sleeved on the surface of the oversheath layer in a reversal way through a spring. The whole armored optical fiber jumper wire is protected by steel armor, the anti strong pressure and stretch-proof function of the armored optical fiber jumper wire can be realized, the jumper wire can be prevented from being damaged by rats and worms, using stability can be guaranteed, and practicality can be realized.

Description

The Novel armored optical patchcord

Technical field

The utility model relates to a kind of wire jumper, relates in particular to a kind of Novel armored optical patchcord.

Background technology

So-called armored fiber optic (optical cable) wraps " armor " of protective exactly again in the outside of optical fiber, be mainly used in satisfying the requirements such as client's mouse bite preventing, moisture proof.Armored fiber optic has important application in telecommunication optical fiber intercity line, a secondary primary transmission.But the armored fiber optic that general webmaster touches usually is mostly for connect all two optical network units of usefulness in machine room building inside.Such armored fiber optic length is relatively short.Be commonly referred to armored jumper.General armored jumper outside flesh side face has the layer of metal armour, and the inside fibre core is protected, and the anti-stretch-proof function of suppressing is arranged, the effect such as can mouse bite preventing damage by worms.Armored jumper consumption in Fiber to the home engineering is very large, because armored jumper goes for the installment inside and outside room wiring, for performance parameters, the mechanical properties of armored jumper higher requirement is arranged.Because added one deck armored protective layer in the structure of the relative ordinary optical cable of armored optical cable, this curing process to armored jumper has just had new problem.When existing armouring light wire jumper solidifies; that external sheath layer and the steel armour layer of end are all peeled off; optical fiber and tight sleeve layer are inserted in the plug core tail handle; its joint portion does not have steel armour layer covering protection; mechanical property is difficult to reach the 50N tensile property, can not reach that armored jumper anti-is suppressed the stretch-proof function, the effect such as can mouse bite preventing damage by worms.And because steel armour layer can cause in use at the unconnectedness of lock pin afterbody, steel armour layer shrinks toward middle, causes the pulling force that connects head end excessive and affect parameter.

Summary of the invention

Problem for above-mentioned prior art existence; the utility model provides a kind of Novel armored optical patchcord; guaranteed that whole piece armored fiber optic wire jumper is all under the protection of steel armour; realized the anti-stretch-proof function of suppressing of armored fiber optic wire jumper; the effect such as can mouse bite preventing damage by worms; guaranteed the stability of using, very practical.

The technical solution of the utility model is: a kind of Novel armored optical patchcord, comprise the wire jumper body, described wire jumper body comprises fibre core, fibre core is socketed with steel armour layer, fibrage and external sheath layer outward successively, the wire jumper body end is provided with lock pin, the fibre core of wire jumper body end and steel armour layer penetrate in the caudal peduncle of lock pin together, and the fibrage of wire jumper body end is by the anti-external sheath layer surface that is placed in of spring.

As preferably, described fibre core is 0.9 tight tube fiber.

The beneficial effects of the utility model are: the fibre core of the utility model wire jumper body end and steel armour layer penetrate in the caudal peduncle of lock pin together; guaranteed that whole piece armored fiber optic wire jumper is all under the protection of steel armour; realized the anti-stretch-proof function of suppressing of armored fiber optic wire jumper; the effect such as can mouse bite preventing damage by worms; and because steel armour and plug core tail handle limit are in one; how long product optics energy parameter is no matter can not change; the connector pulling force can reach 100N especially; thereby guaranteed the stability of using, very practical.

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

Embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of Novel armored optical patchcord comprises the wire jumper body, and described wire jumper body comprises fibre core 1, and in the present embodiment, as preferably, described fibre core 1 is 0.9 tight tube fiber.Fibre core 1 outer steel armour layer 2, fibrage 3 and the external sheath layer 4 of being socketed with successively, the wire jumper body end is provided with lock pin 6, the fibre core 1 of wire jumper body end and steel armour layer 2 penetrate in the caudal peduncle of lock pin 6 together, and the fibrage 3 of wire jumper body end is by spring 5 anti-external sheath layer 4 surfaces that are placed in.

The concrete solidification process of the utility model is as follows: need stay the long fibrage 3 of about 5mm and the long steel armour layer 2 of 8mm after at first the wire jumper body end being peeled off.After with spring 5 the anti-cover of the fibrage 3 of end being blocked, stay the long steel armour layer 2 of 8mm and 0.9 tight tube fiber.Through 6 li of lock pins, in the present embodiment, the caudal peduncle of lock pin 6 is larger than existing plug core tail handle together with 0.9 tight tube fiber for the steel armour layer 2 that remaining in advance 8mm is long.The length that steel armour layer 2 pierces into lock pin 6 caudal peduncles has 3mm.

More than a kind of Novel armored optical patchcord provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To change of the present utility model with to improve will be possible, and can not exceed design and the scope that accessory claim can be stipulated.

Claims (2)
