A LC-typed duplex connector includes a connecting head assembly, a boot assembly and a handle. The handle includes a first elastic structure portion, a second elastic structure portion and a hand shank portion. When the second elastic structure portion is detached from the boot assembly, the first elastic structure portion is detached from the connecting head assembly under the action of the hand shank portion, achieving the detachment and alternate side operation of the LC-typed duplex connector. The detachable handle can efficiently fasten the connecting head assembly with the boot assembly together. The first and second elastic structure portions are easier to detach from the connecting head assembly and the boot assembly respectively under the action of the hand shank portion. Moreover, the hand shank portion is matched with the tail end of the boot assembly, thereby improving efficiently the space utilization of the panel.

The optical cable is provided with an optical cable securing device, an optical cable strengthening component being secured to the optical cable securing device, and the optical fiber within the optical cable passes through the optical cable securing device. The optical fiber connector assembly also comprises a first port end cap; the optical cable securing device is separate from the optical fiber connector, and fits within the accommodating cavity therein; the outer end of the end cap possesses an arrestor wall, which prevents the optical cable securing device from being pulled out of the accommodating cavity within the end cap; additionally there is a compressed spring provided between the end cap and the optical fiber adapter, the compressed spring being squeezed between the end surface of the end cap and the end surface of the optical fiber adapter. In this invention, since there is only a compressed spring provided on one side of the optical fiber adapter, the compressed spring being squeezed between the end cap and the end surface of the optical fiber adapter, the overall axial and radial size of the optical fiber connector assembly is reduced.

The invention discloses a jumper-connection-free copper cable distributing frame for a 19-inch machine cabinet. The jumper-connection-free copper cable distributing frame comprises an upper cover assembly, a tray suite, a parking space assembly and a routing slot, wherein a liner plate in the parking space assembly is assembled in an adjustable slot position of an upper cover of the upper cover assembly through a liner plate hole via screws; a sliding edge of a tray in the tray suite is put in a guide slot in a guide rail of the upper cover assembly; the routing slot is fitted with a positioning surface on the guide rail of the upper cover assembly through a positioning surface in the routing slot; and the routing slot is mounted in the guide rail of the upper cover assembly by a hook in the routing slot and a limiting surface of the upper cover assembly. The jumper-connection-free copper cable distributing frame has the advantages that 1) the space in an optical fiber junction box is fully used, and a copper cable jumper with a certain length can be stored for being directly connected to equipment; 2) the distributing frame has the routing slot, so that an additional wire-arranging frame is not required; 3) a copper cable module is pre-terminated in factories and then assembled on site for use, so that the terminating quality is ensured, and the copper cables are good in consistency; and 4) the copper cables are independently coiled in the tray, so that the interference among the copper cables is avoided.

The invention relates to a rapid hot melt type optical fiber connector which is characterized by comprising a core inserting component, a connector shell, a prefabricated optical fiber, a connecting lining, a cable end optical fiber, a thermal shrinkage protecting tube, a tail part shell and a tightening screw cap. The connector has the following advantages: 1), as the problem of thrusting needle return is solved by utilizing a surplus optical fiber section, and an optical fiber cable is tightly clamped with a connector shell, a front end inserting core is not driven to move together when the tail optical fiber cable of the connector is stressed, so that the problem that the communication is interrupted as the tail part optical fiber cable of a conventional connector is stressed when being used is solved; 2), the problem that too many components are assembled in the construction process is solved; 3), the problem that most conventional hot melt type optical fiber connectors are low in success rate and cannot be used repeatedly is solved; and 4), the rapid hot melt type optical fiber connector is applicable to various rapid hot melt type optical fiber connectors such as an SC (straight connector), an LC (lucent connector) and an FC (fixed connector) with coating layer optical fibers, 0.9 optical fiber cables, 2.0 circular optical fiber cables, 3.0 circular optical fiber cables and butterfly optical fiber cables.

The invention relates to a hot-melt field-assembled optical fiber connector. The connector comprises a front bracket, a connecting bracket, a ferrule, an optical fiber protector, a prefabricated optical fiber, a user side optical fiber, a heat-shrinkable protective tube, a rear bracket assembly, a screwing rear seat, an inserted core assembly and a spring. The connector has the following advantages: 1) the connector can be reused twice, thus increasing the assembly success rate, saving the field assembly time and lowering the cost; 2) the defect that the properties of the optical fiber quick connector are poorer because the bending radius of the optical fiber is insufficient, which is caused by insufficient length of the additional section, is overcome, and as the additional section of the optical fiber is the prefabricated optical fiber, the anti-bending optical fiber can be used, the bending radius is smaller, the additional section of the optical fiber can be shorter and the whole length of the optical fiber connector is reduced; 3) the optical fiber additional section welded twice is preposed, so the front end of the connector is a whole; and 4) the internal structure is suitable for various types of hot-melt field-assembled optical fiber connectors such as SC and LC and 0.25mm and 2.0mm optical cables.
