a body into which the signal pin is inserted and which is electrically isolated from the signal pin; a first housing having a hollow portion into which one end of the body is inserted, a thread groove and at least one protruding portion or a plurality of fixing grooves formed at an inner circumferential surface of the other end thereof; and a second housing having a hollow portion into which the other body end is inserted and through which the second housing is moved along an outer circumferential surface of the body in an axial direction. ## Claims ### Claim 1 A connector for preventing unlocking, comprising: a signal pin transferring a signal; a body into which the signal pin is inserted and which is electrically isolated from the signal pin by an insulator and transfers a ground voltage; a first housing having a hollow portion defined therein, into which one end of the body is inserted, a thread groove for screw-coupling, which is defined in an inner circumferential surface of one end thereof, and at least one protruding portion or a plurality of fixing grooves formed on or in an inner circumferential surface of the other end thereof; and a second housing having a hollow portion defined therein, into which the other end of the body is inserted and through which the second housing is moved along an outer circumferential surface of the body in an axial direction, and one of the at least one protruding portion and the plurality of fixing grooves, which is not formed at the first housing but is formed on or in an outer circumferential surface of one end thereof, wherein, when the one end of the second housing is inserted and fixed between the inner circumferential surface of the other end of the first housing and the outer circumferential surface of the body, the at least one protruding portion is coupled in the plurality of fixing grooves so as to prevent rotation of the first housing. ### Claim 2 (depends on 1) The connector of claim 1, wherein, when the at least one protruding portion is formed on the inner circumferential surface of the other end of the first housing, the fixing grooves are formed in the outer circumferential surface of the one end of the second housing, and when the fixing grooves are formed on the inner circumferential surface of the other end of the first housing, the at least one protruding portion is formed in the outer circumferential surface of the one end of the second housing. ### Claim 3 (depends on 1) The connector of claim 1, wherein, when the thread groove of the first housing is screw-coupled, the second housing is fixed in a state in which the fixing grooves and the at least one protruding portion are separated from each other and thus prevented from being moved in an axial direction, and when the at least one protruding portion is coupled in the fixing grooves, the second housing is fixed and prevented from being moved in the axial direction and rotated. ### Claim 4 (depends on 3) The connector of claim 3, further comprising an elastic body which is supported by the body and provides elasticity to the second housing moving in the axial direction. ### Claim 5 (depends on 4) The connector of claim 4, wherein, when the at least one protruding portion is coupled in the fixing grooves, the elastic body provides the elasticity to the second housing so as to prevent the second housing from being moved in the axial direction. ### Claim 6 (depends on 4) The connector of claim 4, wherein the body has at least one protrusion formed on the other end thereof, and the second housing has at least one through-hole defined in the other end thereof, in which the at least one protrusion is coupled to prevent the second housing from being moved in the axial direction and rotated. ### Claim 7 (depends on 5) The connector of claim 5, wherein the through-hole comprises an axial movement preventing through-hole defined in a direction that is not parallel with the axial direction so that the protrusion is coupled therein and thus the second housing is fixed to the body and prevented from being moved in the axial direction; and a rotation preventing through-hole which is integrally defined with the axial movement preventing through-hole and defined in the axial direction so that the protrusion is coupled therein and thus the second housing is fixed to the body and prevented from being rotated. ### Claim 8 (depends on 6) The connector of claim 6, wherein the second housing comprises a first coupling portion which has the fixing grooves defined in an outer circumferential surface thereof, and is moved along the outer circumferential surface of the body in the axial direction, when receiving the elasticity from the elastic body, such that the at least one protruding portion formed on the first housing is inserted into the fixing grooves; and a second coupling portion which is integrally formed with the first coupling portion, and has larger inner and outer diameters than the first coupling portion, and of which one end is in close contact with the other end of the first housing when a portion thereof coupled with the first coupling portion receives the elasticity from the elastic body, and the other end has the at least one through-hole. ### Claim 9 (depends on 6) The connector of claim 6, wherein the second housing comprises a first coupling portion which has the at least one protruding portion defined in an outer circumferential surface thereof, and is moved along the outer circumferential surface of the body in the axial direction, when receiving the elasticity from the elastic body, is configured such that the at least one protruding portion is inserted into the fixing grooves defined in the first housing; and a second coupling portion which is integrally defined with the first coupling portion, and has larger inner and outer diameters than the first coupling portion, and of which one end is in contact with the other end of the first housing when a portion thereof coupled with the first coupling portion receives the elasticity from the elastic body, and the other end has the at least one through-hole. ### Claim 10 (depends on 1) The connector of claim 1, wherein an end of the protruding portion has a rounded shape, and a boundary portion between the fixing grooves has a smaller width than the protruding portion so that the protruding portion and the fixing grooves are easily coupled with each other, and an end of the boundary portion on a side of the protruding portion has an inclined portion. ### Claim 11 (depends on 1) The connector of claim 1, wherein the first housing has an axial movement preventing portion which protrudes along an inner circumferential surface thereof between the thread groove and the portion on which the at least one protruding portion or the fixing grooves are formed so as to be inserted into a groove defined in the outer circumferential surface of the body and thus prevent the first housing from being moved in the axial direction. ### Claim 12 (depends on 1) The connector of claim 1, wherein the connector for preventing unlocking is a radio frequency (RF) connector transferring a high frequency signal.
