a moving cover provided with a moving cover lock, and assembled at a predetermined position of a male housing to support male terminals disposed in a receiving space of the male housing;
a male housing lock provided in the male housing, and for preventing the moving cover from being moved in the insertion direction of a female housing at the predetermined position of the male housing by supporting the moving cover lock when the female housing is not inserted into the receiving space; and
a female housing lock provided in the female housing, and the moving cover is moved by the male housing lock by separating the moving cover lock from the male housing lock;
wherein the moving cover lock is locked to the female housing lock to be moved with the female housing lock when the female housing is separated from the receiving space, such that the moving cover returns to the predetermined position;
wherein the moving cover comprises:
a moving plate provided with a plurality of through holes that the male terminals penetrate; and
a moving cover lock provided in the moving plate, and contacting a top horizontal surface of the male housing lock when the moving plate is disposed at a predetermined position;
wherein the moving cover lock comprises:
a first lock member formed integrally on the moving plate; and
a second lock member formed integrally on the moving plate, and in line with the first lock member; and
wherein the female housing is pushed by the female housing lock entering between the first lock member and the second lock member when being inserted into the receiving space, such that the first lock member and the second lock member are separated from the top horizontal surface of the male housing lock.
2. The terminal protection device of the connector of claim 1 ,
wherein the first lock member is provided with a first inclined surface pushed while contacting the bottom portion of the female housing lock when the female housing is inserted into the receiving space; and
wherein the second lock member is provided with a second inclined surface pushed while contacting the bottom portion of the female housing lock when the female housing is inserted into the receiving space.
3. The terminal protection device of the connector of claim 2 ,
wherein the first lock member is provided with a first latching part to which the top horizontal surface of the female housing lock is latched when the female housing is separated from the receiving space, and the first latching part is disposed below the first inclined surface with respect to the insertion direction of the female housing; and
wherein the second lock member is provided with a second latching part to which the top horizontal surface of the female housing lock is latched when the female housing is separated from the receiving space, and the second latching part is disposed below the second inclined surface with respect to the insertion direction of the female housing.
4. The terminal protection device of the connector of claim 3 ,
wherein the first lock member is provided with a first lower inclined surface pushed by contacting the top horizontal surface of the female housing lock when the female housing is separated from the receiving space, and the first lower inclined surface is disposed below the first latching part; and
wherein the second lock member is provided with a second lower inclined surface pushed by contacting the top horizontal surface of the female housing lock when the female housing is separated from the receiving space, the second lower inclined surface is disposed below the second latching part, and the second lower inclined surface is pushed in the direction opposite to the first lower inclined surface.
5. The terminal protection device of the connector of claim 4 ,
wherein the first inclined surface, the first latching part, and the first lower inclined surface are disposed close to the outside surface of the female housing of the inside surface of the male housing and the outside surface of the female housing to contact the female housing lock protruded to the outside surface of the female housing and not to contact the male housing lock protruded to the inside surface of the male housing.
6. The terminal protection device of the connector of claim 4 ,
wherein the second inclined surface, the second latching part, and the second lower inclined surface are disposed close to the outside surface of the female housing of the inside surface of the male housing and the outside surface of the female housing to contact the female housing lock protruded to the outside surface of the female housing and not to contact the male housing lock protruded to the inside surface of the male housing.
7. The terminal protection device of the connector of claim 2 ,
wherein the top portion of the female housing lock is provided with an extension having the width larger than that of the bottom portion of the female housing lock, and
wherein the extension is locked between the first lock member and the second lock member by an elastic restoring force of the first lock member and the second lock member bent by being pushed by the bottom portion of the female housing lock when the female housing is inserted into the receiving space.
8. The terminal protection device of the connector of claim 1 ,
wherein the first lock member is provided with a first bottom horizontal surface locked to the top horizontal surface of the male housing lock when the female housing is not inserted into the receiving space; and
wherein the second lock member is provided with a second bottom horizontal surface locked to the top horizontal surface of the male housing lock when the female housing is not inserted into the receiving space.
9. The terminal protection device of the connector of claim 8 ,
wherein the first bottom horizontal surface is disposed close to the inside surface of the male housing of the inside surface of the male housing and the outside surface of the female housing to contact the male housing lock protruded to the inside surface of the male housing and not to contact the female housing lock protruded to the outside surface of the female housing.
10. The terminal protection device of the connector of claim 8 ,
wherein the second bottom horizontal surface is disposed close to the inside surface of the male housing of the inside surface of the male housing and the outside surface of the female housing to contact the male housing lock protruded to the inside surface of the male housing and not to contact the female housing lock protruded to the outside surface of the female housing.
11. The terminal protection device of the connector of claim 1 ,
wherein the inside surface of the male housing is provided with a separation preventing projection, and a separation preventing bar locked to the separation preventing projection when the moving cover returns to a predetermined position is provided at the edge of the moving plate.
