Gun-type optical connector grinding device

Abstract

A gun-type optical connector grinding device can include a gun-type housing including a gripping part to be gripped with one hand, and a head coupling part disposed above the gripping part. The connector can include a detachable head unit which is detachably coupled to the head coupling part of the gun-type housing and on one side of which can include a connector insertion terminal block into which an optical connector to be ground is inserted. The connector can include a grinding-type gear module which is provided in the detachable head unit and on one side of which can include a connector grinding part for grinding the optical connector inserted into the connector insertion terminal block.

1 . A gun-type optical connector grinding device comprising:
 a gun-type housing including a gripping part to be gripped with one hand, and a head coupling part disposed above the gripping part;   a detachable head unit which is detachably coupled to the head coupling part of the gun-type housing and on one side of which includes a connector insertion terminal block into which an optical connector to be ground is inserted;   a grinding-type gear module which is provided in the detachable head unit and on one side of which includes a connector grinding part for grinding the optical connector inserted into the connector insertion terminal block;   a gear assembly which is coupled to the grinding-type gear module to be gear-engaged on one side thereof and rotates the grinding-type gear module;   an electric motor which is provided in the gripping part of the gun-type housing and connected to the gear assembly, and electrically drives the gear assembly in order to rotate the grinding-type gear module; and   an on/off switch which is provided on one side of the gun-type housing and connected to the electric motor, and inputs a signal for an on/off operation of the electric motor.   
     
     
         2 . The gun-type optical connector grinding device of  claim 1 , wherein the detachable head unit includes:
 a bottom head which is detachably coupled to the head coupling part of the gun-type housing and on one side of which the gear assembly is disposed;   a top head which is coupled to an upper portion of the bottom head and in which an opening through which the grinding-type gear module is partially exposed is formed; and   a rotating cover which rotatably opens or closes the opening of the top head and is coupled to the top head with a hinge on one side thereof,   wherein the connector insertion terminal block is provided on the rotating cover and communicates with the connector grinding part of the grinding-type gear module through the opening of the top head.   
     
     
         3 . The gun-type optical connector grinding device of  claim 2 , wherein the connector insertion terminal block is disposed on the rotating cover in a dual structure. 
     
     
         4 . The gun-type optical connector grinding device of  claim 1 , wherein a separating plate for separating a space from the detachable head unit is provided in the head coupling part of the gun-type housing, and
 water leakage toward the electric motor is prevented when the optical connector is ground due to the separating plate and the bottom head.   
     
     
         5 . The gun-type optical connector grinding device of  claim 1 , wherein a rechargeable battery which is connected to the electric motor and provides power to the electric motor is provided in the gripping part of the gun-type housing,
 a charging terminal for charging the rechargeable battery is provided on one side of the gun-type housing, and   the charging terminal is allowed to be opened or closed by a terminal cap.   
     
     
         6 . The gun-type optical connector grinding device of  claim 1 , wherein the grinding-type gear module includes:
 a planetary gear which is in contact with the connector grinding part and integrally formed with the connector grinding part; and   a module connection part which is connected to the connector grinding part on an inner side of the planetary gear.   
     
     
         7 . The gun-type optical connector grinding device of  claim 6 , wherein the gear assembly includes:
 a motor connection shaft connected to a motor shaft of the electric motor;   a first gear to which one side of the motor connection shaft is coupled and which co-rotates with the motor connection shaft;   a module eccentric connection unit which is disposed in a central region of the first gear, connected to the motor connection shaft, and supports the grinding-type gear module eccentrically to one side from a central shaft of the first gear;   a second gear having fewer teeth than the first gear of which one side externally touches the first gear;   a third gear externally touching another side of the second gear;   a fourth gear which has more teeth than the second gear and the third gear, is connected coaxially with the third gear, and co-rotates with the third gear; and   a fifth gear including an outer gear part that externally touches the fourth gear, and an inner gear part that internally touches the planetary gear of the grinding-type gear module, wherein the fifth gear has more teeth than the first gear, and is disposed above the first gear to surround the module eccentric connection unit.   
     
     
         8 . The gun-type optical connector grinding device of  claim 7 , wherein an eccentric connection block which is disposed eccentrically from a center of the module eccentric connection unit and coupled to the module connection part of the grinding-type gear module is provided in the module eccentric connection unit,
 the second gear is a gear having a stepped structure in which one side and another side thereof are gear-engaged with the first and third gears, and   the grinding-type gear module performs a grinding process on the optical connector while rotating and revolving.
