[ The separation preventing protrusion 11 may be formed on the inner wall of the cap housing 10. For example, the lower portion of the release preventing projection 11 may include a flat shape, and the upper portion may include an inclined shape. According to this configuration, when the shield plate 20 is inserted into the cap housing 10, it can be easily mounted through the inclined shape of the upper portion of the detent protrusion 11. It is also possible to prevent the cap 20 from being separated from the cap housing 10 by the flat shape of the lower portion of the detachment protrusion 11 when the protection plate 20 is pulled out of the cap housing 10. [ The side wall of the protection plate 20 may not have a portion protruding inward or outward when viewed from above. The thickness of the side wall of the protection plate 20 may have a thickness of, for example, 0.8 to 1.0 mm.

The shield plate support lever 12 includes a lever body portion 121 extending from an inner wall of the cap housing 10, for example, an inner bottom wall, a receiving portion 122 protruding from the lever body portion 121, And a working part 123 connected to the body part 121 or the receiving part 122. For example, the lever body portion 121, the receiving portion 122, and the operating portion 123 may be integrally formed. The lever body part 121 is provided in a variable shape and can be deformed or moved in a lever retreat space 13 formed between the inner side surface of the cap housing 10 and the lever body part 121. [ The upper portion of the abutment portion 122 may include a flat shape, and the lower portion may include an inclined shape. The acting portion 123 may be formed higher than the receiving portion 122. For example, each of the upper and lower portions of the working portion 123 may include an inclined shape.

The shield plate 20 can move up and down within the cap housing 10 within the predetermined distance L depending on whether the plug housing 30 is engaged or not.

The protection plate 20 has a receiving groove 21 capable of receiving the operating portion 123, a cap engaging portion 22 capable of being supported by the receiving portion 122, a plug- A lever sliding space 25 for providing a space in which the lever body part 121 can be moved, a deformation receiving space 26 for providing a deformable space for the plug engaging part 23, And a protrusion engaging portion 27 that can be engaged with the detachment preventing protrusion 11.

The receiving groove 21 may be a recess recessed inward from the rim of the bottom wall of the shield plate 20. [ In other words, the receiving groove 21 can be formed by cutting a part of the bottom wall of the shield plate 20. [ A portion of the protective plate 20 where the receiving groove 21 is not formed can be supported by the receiving portion 122. A portion of the bottom wall of the protection plate 20 supported by the support portion 122 may be referred to as a cap engagement portion 22. [ The cap engaging portion 22 can be understood to refer to a portion of the bottom wall of the protecting plate 20 which overlaps with the receiving portion 122 along the inserting direction of the protecting plate 20 have. According to such a structure of the cap engaging portion 22, it is not necessary to separately form an interference structure for supporting the shield plate 20 in a spaced state from the bottom of the cap housing 10, outside the shield plate 20 By reducing the distance between the side wall of the protection plate 20 and the inner wall of the cap housing 10, space efficiency can be improved and the entire connector assembly 1 can be downsized. More specifically, when the cap engagement portion 22 is formed on the outer side of the protection plate 20, the protection plate support lever 12 for supporting the cap engagement portion 22 should be located outside the protection plate 20 It is necessary to provide a certain clearance space between the side wall of the protection plate 20 and the inner wall of the cap housing 10 by the space occupied by the protection plate supporting lever 12, but according to the embodiment, .

The lever sliding space 25 may be a hole or a groove formed in the side wall of the protection plate 20. [ For example, the lever sliding space 25 may be formed by cutting a part of the side wall of the shield plate 20. The lever sliding space 25 prevents the shield plate supporting lever 12 from interfering with the rest of the shield plate 20 excluding the cap engaging portion 22 when the shield plate 20 is inserted into the cap housing 10 . With this structure, even if the side wall of the protection plate 20 has a thin plate shape, the interference structure between the protection plate 20 and the protection plate supporting lever 12 can be formed.

The plug engagement portion 23 can be engaged with or separated from the fixing protrusion 33 (see Fig. 4) protruding from the side wall of the plug housing 30. The plug engagement portion 23 can be formed in a variable shape in the side wall of the protection plate 20. The plug engagement portion 23 may be formed on another edge of the protection plate 20 on which the receiving groove 21 is not formed. The shape of the plug engagement portion 23 can be changed on the plane including the side wall of the protection plate 20 in accordance with the interference with the fixing projection 33. [ This structure reduces the distance between the side wall of the protection plate 20 and the inner wall of the cap housing 10 as compared with the case where the plug engagement portion 23 is deformed in the direction perpendicular to the side wall of the protection plate 20. [ The space efficiency can be improved and the entire connector assembly 1 can be miniaturized. More specifically, when the plug engagement portion 23 is deformed in a direction perpendicular to the side wall of the protection plate 20, the side wall of the protection plate 20 and the cap It is necessary to provide a predetermined clearance space located between the inner walls of the housing 10, but according to the embodiment, the clearance is not necessary, so that the above effect can be achieved. A concrete embodiment of the plug engagement portion 23 will be described later with reference to Fig.

The deformation receiving space 26 may be provided on both sides of the plug engagement portion 23, for example. The deformation accommodating space 26 may be formed by cutting the periphery of a portion of the side wall of the protection plate 20 where the plug engaging portion 23 is formed. According to this structure, even if the side wall of the protection plate 20 has a thin plate shape, the interference structure between the protection plate 20 and the plug housing 30 can be formed.

The projection locking portion 27 can be engaged with or detached from the separation preventing projection 11. [ The protrusion latching portion 27 can be formed in a variable shape in the side wall of the protection plate 20. [ The protruding latching portion 27 can be bent toward the inside of the protection plate 20 in accordance with the interference with the release preventing projection 11. [ The projection 27 has a horizontal portion 271 which can be caught by the lower end of the separation preventing projection 11 and a bending portion 271 which can be bent when the horizontal portion 271 interferes with the separation preventing projection 11 272). The horizontal portion 271 and the bending portion 272 may be formed by cutting a part of the side wall of the protection plate 20, for example. For example, the projection locking portion 27 may have a U-shape as shown in Fig.

The plug housing 30 includes a separating protrusion 32 for separating the cap engaging portion 22 and the shield plate supporting lever 12 by respectively moving the shield plate supporting lever 12, And may include a droplet projection 33. For example, the lower part of each of the separating projection 32 and the fixing projection 33 may be a sloped surface, and the upper part may be a flat surface.

The lever housing 40 may include an operating portion for allowing an operator to rotate the plug housing 30 when the plug housing 30 is engaged or disengaged.

The cap housing 10, the protection plate 20, the plug housing 30, and the lever housing 40 may be made of a material having insulation and rigidity such as plastic, ceramic resin or the like.

A method of joining a connector assembly 1 for coupling a cap housing 10 and a plug housing 30 according to an embodiment of the present invention will be described. First, as shown in FIG. 3, The protective plate 20 protecting the tab terminal is mounted in a state (initial state).

This mounting is carried out by the operator pushing the protection plate 20 into the cap housing 10 when manufacturing the connector according to the present invention.

That is, the protection plate 20 is inserted in the open upper portion of the cap housing 10 shown in Fig. By this simple insertion, the protection plate 20 is blocked by the separation preventing protrusion 11 of the cap housing 10, but since the separation preventing projection 11 has the inclined surface from the top to the bottom, The protective plate 20 easily passes through the separation preventing protrusion 11. 3, after the protection plate 20 passes through the separation preventing protrusion 11, a cap engaging portion (not shown) formed on the bottom wall of the protecting plate 20 is attached to the protecting plate supporting lever 12 of the cap housing 10 22 are caught and held at a distance of a certain distance L from the inner bottom wall of the cap housing 10. This state may be a state (initial state) in which a part (tip end) of a plurality of tab terminals built in the cap housing 10 is inserted into a plurality of grooves formed in the protection plate 20, respectively.

More specifically, when the protector 20 is inserted into the cap housing 10, in the process of protruding the protrusion 27 of the protector 20 beyond the protrusion 11 of the cap housing 10, 20, the upper end of the horizontal portion 271 of the projection locking portion 27 can be caught by the lower end of the detachment prevention projection 11. As a result, Due to such an operation, the shield plate 20 may not be detached from the cap housing 10.

The cap engaging portion 22 of the shield plate 20 can be supported by the receiving portion 122 of the shield plate supporting lever 12 at a position where the projection engaging portion 27 completely passes over the separation preventing protrusion 11. [ The protection plate 20 can not enter the cap housing 10 any more and thus the protection plate 20 is separated from the bottom wall of the cap housing 10 by a predetermined distance L (Initial state), it is possible to protect the tab terminals of the cap housing 10.
