DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The disclosure will be further described below by way of embodiments in combination with the accompanying drawings.
As shown in FIGS. 1 and 2, a LC-typed duplex connector includes a connecting head assembly 1; a boot assembly 2 matching with the connecting head assembly 1; and a handle 3 for rapidly detaching the connecting head assembly 1 from the boot assembly 2. The handle 3 includes a first elastic structure portion 31 which is disposed at the front end of the handle 3 for matching with the connecting head assembly 1; a second elastic structure portion 32, which is disposed at the middle of the handle 3 for matching with the front end of the boot assembly 2; and a hand shank portion 33, which is disposed at the tail end of the handle 3 for matching with the tail end of the boot assembly 2. When the second elastic structure portion 32 is detached from the boot assembly 2, the first elastic structure portion 31 is detached from the connecting head assembly 1 under the action of the hand shank portion 33, achieving the detachment and alternate side operation of the LC-typed duplex connector.
As a preferable embodiment, the first elastic structure portion 31 includes two structurally identical elastic arms 311 disposed at the front end of the handle 3. First elongated slots 3111 are disposed at the end portions of two elastic arms 311, respectively, for improving the elasticity of the end portions. Positioning embosses 3112 are disposed outwardly on both sidewalls at the end portions of the elastic arms 311. The connecting head assembly 1 includes connecting head casings 10. Through holes 101 run vertically through the front end of the connecting head casings 10 for matching with positioning blocks 3113 at the end portion of the elastic arms 311. Positioning holes 102 run transversely through the sidewalls at upper and lower ends of the through holes 101 for matching with the positioning embosses 3112. In this configuration, the first elongated slots 3111 are configured to divide positioning blocks 3113 at the end portion of the elastic arms 311 into two, improving efficiently the elasticity of the end portion of the elastic arms when the positioning blocks 3113 are matched with the through holes 101, and facilitating the positioning blocks to be matched with the through holes 101. The positioning embosses 3112 are disposed on both sidewalls of the elastic arms for matching with the positioning holes 102 on the sidewalls of the through holes, which prevent the positioning blocks 3113 at the end portion of the elastic arms 311 from popping off the through holes 101 on the connecting head casing 10 after assembled with the through holes 101. As a preferable embodiment, the positioning embosses 3112 are disposed at sidewalls of the positioning blocks in contact with the through holes 101.
Moreover, for facilitating to turn the LC-typed duplex connector over 180° for the alternate side operation thereof and avoiding directly contacting thinner cable core with the hands and further preventing the cable core from being broken, the positioning holes 102 are disposed on the sidewalls at the upper and lower ends of the through holes 101 for matching with the positioning embosses 3112 such that the handle 3 is capable of matching with the upper and lower faces of the LC-typed duplex connector, further ensuring efficiently the alternate side operation after turning the LC-typed duplex connector over 180°.
As shown FIG. 3, the second elastic structure portion 32 includes a first supporting wall 321 disposed vertically on the undersurface at the middle of the handle 3; a base 322 disposed horizontally on a bottom end of the first supporting wall 321; and a clamping arm 323 disposed vertically on the base 322. A second elongated slot 3231 passes through the middle portion of the clamping arm 323 for improving the elasticity of the clamping arm 323, and clamping hooks 3232 are disposed on both sidewalls at the bottom end of the clamping arms 323. The boot assembly 2 includes a boot 24 and a branching clamp 21 matching with a port at the front end of the boot 24. A clamping hole 241 pass vertically through an upper wall and a lower wall at the front end of the boot assembly 2 for matching with the clamping arm 323, and clamping grooves 242 are disposed on an upper wall and a lower wall of the boot 24 at the upper and lower ends of the clamping hole 241, respectively, for matching with the clamping hook 3232. When it is required to implement the alternate side operation and the disassembly of the connector, two sidewalls at the bottom end of the clamping arm are pushed inwardly, and then the hand shank is lift up and the positioning blocks at the end portion of the elastic arm 311 in the first elastic structure portion slip off the through holes 101, the handle 3 is detached from the connecting head assembly 1 and the boot assembly 2 by this time. For ensuring the handle efficient connection with the connecting head assembly 1 and the boot assembly 2 after alternate side operation, the clamping grooves 242 are disposed on the upper and lower walls of the boot 24 at the upper and lower ends of the clamping hole 241, respectively, for matching with the clamping hook 3232, thereby ensuring that the clamping arms 323 are capable of being snapped in the upper and lower walls of the boot.
Moreover, the lever principle is adopted among the first and second elastic structure portions 31 and 32 and the hand shank portion 33. When a force is applied on the hand shank portion 33, the second elastic structure portion 32 corresponds to a fulcrum such that the ends portion of the elastic arms in the first elastic structure portion are easy to slip off the through holes 101, thereby implementing conveniently and rapidly the assembly and the alternate side operation of the LC-typed duplex connector.
As a further preferable embodiment, as shown in FIGS. 3 to 5, the hand shank portion 33 includes a recess 331 matching with an outer surface of the tail end of the boot assembly 2; and a tail shank 332 disposed at the tail end of the hand shank portion 33 for pressing down and lifting up the handle 3. Skidproof stripes are disposed at the upper and lower surfaces of the tail shank 332, and a third elongated slot 3311 pass through the bottom face of the recess 331. In this configuration, the recess 331 is configured to be fit tightly with the boot such that the handle is integrated with the boot assembly, further reducing efficiently the size of the LC-typed duplex connector. Moreover, the tail shank 332 is disposed at the hand shank portion 33 to avoid the fingers entering between two connectors for disassembly, thereby implementing conveniently and rapidly the assembly and the alternate side operation.
As a further preferable embodiment, the connecting head assemble 1 further includes ceramic ferrules 12 which are inserted within the connecting head casing 10; springs 13 through which the ceramic ferrules 12 run; and connector casing lengthened caps 14 which are matched with the tail ends of the ceramic ferrules 12. The boot assembly 2 further includes a supporting ring 22 which is disposed at the tail end of the branching clamp 21 and a compression ring 23 through which the branching clamp 21 runs. Skidproof stripes are disposed at the outer surface of the tail end of the branching clamp 21 and at the outer surface of the supporting ring 22 such that the tail end of the branching clamp 21, the supporting ring 22 and the compression ring 23 which run through each other fit tightly for preventing the various parts from slipping off each other.
As shown in FIG. 6, tail ends of a connector casing lengthened caps 14 are inserted into the branching clamping 21 and are matched with the front end of the branching clamping 21. A cylinder 141 and a square 142 are successively disposed at the tail end of each of the connector casing lengthened cap 14 from inside to outside. First and second cambered flanges 143 and 144 are disposed symmetrically on upper and lower surfaces of the square. The tail end of the connector casing lengthened cap 14 is capable of matching with the front end of the branching clamp 21 stably and reliably by this configuration. Further preferably, two fixed positions are disposed at left and right sides of the branching clamp 21 symmetrically, respectively, for matching with the tail end of each of the connector casing lengthened cap 14. The first and second cambered flanges 143 and 144 can constrain the movement between the connector casing lengthened cap 14 and the branching clamp 21. The square 142 can prevent the connector casing lengthened cap 14 from rotating within the front end of the branching clamp 21.
The technical principle of the disclosure has been described in combination with the specific embodiments above. These descriptions are only intended to explain the principle of the disclosure, but not to limit the protection scope of the disclosure in any way. Base on this explanation, other specific embodiments can be conceived by those skilled in the art without any creative labor, and fall within the protection scope of the disclosure.
