Abstract

The utility model discloses a rubber-insulated optical cable fixing structure for a rubber-insulated optical cable connector. The rubber-insulated optical cable fixing structure for the rubber-insulated optical cable connector comprises a rubber-insulated cable connecting head a rubber-insulated optical cable which is inserted into a rubber-insulated cable hole of the rubber-insulated cable connecting head, and a rubber-insulated cable clamping component which is arranged between the rear end of the rubber-insulated cable connecting head and the rubber-insulated optical cable and is used for tightly clamping the rubber-insulated optical cable, wherein the rubber-insulated cable clamping component at least comprises two pins; the distance between the two adjacent pins is smaller than the length of the short side of the rubber-insulated optical cable; insertion holes allowing the pins to be inserted in are formed in a pipe wall at the rear end of the rubber-insulated cable connecting head, and the pins of the rubber-insulated cable clamping component penetrate through the insertion holes and are inserted into a protective sheath of the rubber-insulated optical cable and the rubber-insulated cable connecting head, so that the reliable fixing between the connecting head of the connector and the optical fiber can be realized. The rubber-insulated optical cable fixing structure for the rubber-insulated optical cable connector has simple and reasonable structure, small volume and light weight, is low in manufacturing cost and easy to assemble, has few components, and is easy to assemble.

Description

The covered wire cable fixed sturcture that is used for the covered wire cable connector

Technical field

the utility model relates to a kind of optical connector, relates in particular to a kind of covered wire cable fixed sturcture that is used for the covered wire cable connector.

Background technology

covered wire cable is selected as main leading in cable structure by each big operator, and its market consumption increases substantially just year by year, and is corresponding, and the use of the joints of optical fibre made from covered wire cable is also increasing substantially.

normally used joints of optical fibre; The optical cable that uses is conventional single fiber cable, and the tensile elements in the optical cable is high-intensity aramid fiber silk, being connected of the aramid fiber silk in the joints of optical fibre and the optical cable; What adopt is compression bonding method; Mode through flow of metal realizes the purpose that aramid fiber silk and adapter connector are fixed together, and like this, can be delivered at pulling force suffered on the adapter connector on the tensile elements of optical cable.

are then different when making the joints of optical fibre with covered wire cable; Because the tensile elements in the covered wire cable can be steel wire, FRP (glass fiber fortifying fibre) and KFRP (aramid fiber silk fortifying fibre); And the connector loose mail that provides on the market all is to being the structure of reinforcement with the aramid fiber silk; Be used for doing when being the rubber-insulated wire cable joint of reinforcement with steel wire, FRP and KFRP, however can't crimping firm, otherwise be crimped onto one with regard to harmless at all.

Summary of the invention

the utility model purpose is: a kind of covered wire cable fixed sturcture that is used for the covered wire cable connector is provided, and it adopts the pin of rubber-insulated wire holding firmware to block covered wire cable and rubber-insulated wire cable connector simultaneously, thereby realizes the secure fixation between adapter connector and the optical cable; It is simple and reasonable; Volume is little, and is in light weight, low cost of manufacture; And building block quantity is few, and assembling easily.

The technical scheme of the utility model is: a kind of covered wire cable fixed sturcture that is used for the covered wire cable connector; Comprise rubber-insulated wire cable connector, be located in the covered wire cable in the rubber-insulated wire hole of rubber-insulated wire cable connector; And be arranged between rubber-insulated wire cable connector rear end and the covered wire cable, be used to tighten the rubber-insulated wire holding firmware of covered wire cable; Said rubber-insulated wire holding firmware has two pins at least; And the distance between adjacent two pins is less than the bond length of covered wire cable; The rear end tube wall of said rubber-insulated wire cable connector is provided with the jack that supplies pin to insert, and the pin of said rubber-insulated wire holding firmware passes in the sheath and rubber-insulated wire cable connector that jack is plugged in covered wire cable.

are further, two groups of pins before and after said rubber-insulated wire holding firmware has, and every group of pin be two, and the distance between two pins in every group is all less than the bond length of covered wire cable.

for better fixing covered wire cable, and the rubber-insulated wire hole of said rubber-insulated wire cable connector rear end is the dish-shaped hole that cooperatively interacts of the profile with covered wire cable.

the utility model has the advantages that: the utility model adopts four pins of rubber-insulated wire holding firmware to block covered wire cable and rubber-insulated wire cable connector simultaneously; Thereby realize the secure fixation between adapter connector and the optical cable, it is simple and reasonable, and volume is little; In light weight; Low cost of manufacture, and building block quantity is few, and assembling is easily.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the cut-open view of the covered wire cable connector of use the utility model;

Sectional view when the rubber-insulated wire holding firmware tightens covered wire cable in Fig. 2 the utility model.
