The lever 20 may include a fastening groove 21, a fastening protrusion 22, a first fastening portion 25, and a fitting hole 24h. The housing 30 may include a fastening protrusion 31, a fastening base 32, a second fastening portion 36, a release preventing jaw 33, a cable fixing portion 35, and a coupling protrusion 34. In addition, the flexible cable 10 inserted into the connector 1 for a flexible cable may include the escape preventing groove 13h.

The housing 30 may include a front portion and a rear portion facing the front portion. The rear portion of the housing 30 may include a receiving space for insertion of the female connector. Also, the female connector can be inserted through the accommodating space, and the lever 20 and the terminal 40 can be coupled through the front portion of the housing 30. [ In addition, in the housing 30, the flexible cable 10 can be connected to the terminal 40 by using the lever 20. The present invention relates to the connection between the flexible cable 10 and the terminal 40 using the lever 20, and details thereof will be described later.

The housing 30 includes a cable fixing portion 35 protruded in a direction in which the terminal 40 is inserted into the housing 30 (hereinafter referred to as a first direction d1). As shown, unlike other parts of the housing 30, the top of the cable securing portion 35 may be open. The protruding length and position of the cable fixing portion 35 can be variously modified as required. The cable fixing part 35 is fixed to the cable fixing part 35 at a suitable position where the flexible cable 10 can be connected to the terminal 40 by using the lever 20, .

The cable fixing portion 35 may include a flat surface on which the flexible cable 10 can be disposed, and the area of the flat surface varies depending on the extent to which the cable fixing portion 35 is projected. Further, the cable fixing portion 35 may include a protrusion (not shown) capable of separating and fixing the respective terminals included in the terminal 40.

The cable fixing portion 35 may include side walls extending in the direction perpendicular to the first direction d1 and disposed on the left and right sides of the cable fixing portion 35. [ The sidewall may include an inner side wall facing each other and an outer side wall facing each of the inner side walls.

In the present invention, since the cable fixing portion 35 may have an open top shape as shown, a portion of the terminal 40 disposed on the flat surface of the cable fixing portion 35 may be exposed . In the present invention, the open upper portion of the cable fixing portion 35 can be covered by the lever 20, which will be described later.

The fastening protrusions 31 may be disposed on the left and right inner side surfaces of the cable fixing portion 35. Although one fastening projection 31 is shown in this embodiment, another fastening protrusion 31 may be disposed on the other inner side of the cable fixing portion 35 facing the fastening protrusion 31. [ Although the fastening protrusion 31 is shown as being disposed on the inner surface of the cable fixing portion 35 exposed to the outside in the present embodiment, the technical idea of the present invention is not limited thereto. The fastening protrusion 31 can be disposed on the inner side of the housing 30 and connected to the inner side of the cable fixing portion 35. [ The fastening protrusion 31 can be coupled to the fastening groove 21 of the lever 20 to form a rotating shaft and the lever 20 can be separated from and coupled to the housing 30 through the fastening protrusion 31 . Details will be described later.

In the present embodiment, the fastening protrusion 31 has a protruding shape and is fastened to the fastening groove 21 of the lever 20, but is not limited thereto. Therefore, the fastening protrusion 31 can have a groove shape or the like irrespective of its name. That is, if the fastening protrusion 31 is a shape that can be coupled with the lever 20 to form a rotation shaft, the fastening protrusion 31 can be applied without any limitation in shape.

The housing 30 may include a release restricting jaw 33 on the bottom surface of the cable securing portion 35. The release preventing jaw 33 may include a protruding shape, but the technical idea of the present invention is not limited thereto. Therefore, the release preventing jaw 33 can be deformed according to the shape of the release preventing groove 13h engaged with the release preventing jaw 33. [ Also, in this embodiment, although the release preventing tab 33 is shown on the bottom surface of the cable fixing portion 35 as being located in the region adjacent to the left and right inner side walls of the cable fixing portion 35, the present invention is not limited thereto. Therefore, the release preventing jaw 33 can be disposed in the housing 30 without limitation as long as it is at a position corresponding to the release preventing groove 13h included in the flexible cable 10. [

The release preventing jaws 33 can be inserted into the release preventing grooves 13h included in the flexible cable 10 and fastened to each other. Therefore, the separation preventing groove 13h and the separation preventing jig 33 can prevent the flexible cable 10 from being pushed and improve the holding force of the connection structure with the terminal 40. [

The housing 30 may include a pawl 32. The lug 32 may be disposed at the boundary of the open upper portion of the cable fixing portion 35 and the upper closed housing 30. The pawl 32 can be engaged with the latching jaw 22 of the lever 20, thereby fixing and supporting the lever 20. Details thereof will be described later.

The housing 30 may include an engaging projection 34. The engaging projections 34 can be disposed on the outer wall of the left and right side walls of the cable fixing portion 35 and can be inserted into the engaging holes 24h of the lever 20. [ As a result, the engagement strength of the lever 20 with respect to the housing 30 can be enhanced, and the structural stability of the connector 1 can be improved.

The housing 30 may include a second fastening portion 36. The second fastening portion 36 may be disposed at the distal end of the front portion of the housing 30 into which the terminal 40 is inserted. Therefore, when the front portion of the housing 30 is viewed from the front as shown in FIG. 2, the shape of the second fastening portion 36 appears.

The second fastening portion 36 may be a part of the side wall of the cable fixing portion 35 or the side wall of the cable fixing portion 35. The second fastening portion 36 can be engaged with the first fastening portion 25 of the lever 20. Details thereof will be described later.

The technical features of the present invention will now be described with reference to the lever 20. The lever 20 may include a coupling groove 21, a coupling protrusion 22, a first coupling portion 25, and a coupling hole 24h.

The lever 20 may include a front surface corresponding to the front portion of the housing 30 and a rear surface opposed to the front surface. The lever 20 may include left and right side surfaces corresponding to the left and right side walls of the housing 30, connecting the front surface and the rear surface.

Each of the left and right sides of the lever 20 may include a fastening groove 21. The engaging groove 21 may be disposed adjacent to the rear surface of the lever 20.

If the engaging groove 21 can have a concave groove shape, a part of the side wall of the groove can be opened. The open partial sidewall of the coupling groove 21 may form an insertion port and the opening direction may be directed to the upper surface of the lever 20. However, the present invention is not limited thereto.

The fastening groove 21 can be fastened to the fastening protrusion 31 of the housing 30 by using a part of the opened side wall of the fastening groove 21. [ Specifically, the opening projection of the fastening protrusion 31 can be inserted into the fastening groove 21 by using a part of the opened side wall of the fastening groove 21 as an insertion opening of the fastening protrusion 31. In the present invention, the lever 20 includes the engagement groove 21 including the insertion port, so that the lever 20 can be quickly separated or combined with the housing 30. Therefore, the connector for a flexible cable according to the present invention secures structural stability, and the connector for a flexible cable can be easily assembled or disassembled through the above-described structural features.

Further, the fastening protrusion 31 is inserted into the fastening groove 21, so that the rotation axis of the lever 20 can be formed. That is, as shown in FIG. 2, the lever 20 can perform rotational motion including up-and-down motion using the fastening grooves 21 disposed on the left and right sides as rotation axes. In the present embodiment, the engaging grooves 21 are formed in the shape of a groove and the engaging projections 31 are formed in the shape of protrusions, but the present invention is not limited thereto. Therefore, each of the engaging groove 21 and the engaging projection 31 can be a protrusion or a groove irrespective of the name, and can be applied without limitation as long as the shape can be quickly separated or combined.

The lever 20 may include a latching jaw 22 at a rear surface opposed to the front surface corresponding to the direction in which the terminal 40 is inserted. The engaging jaw 22 may have a protruding shape with a step. The latching jaw 22 may have a shape extending leftward and rightward. The length of the latching jaw 22 may be limited depending on the length and shape of the latching bar 32 engaged with the latching jaw 22.

The lever 20 can be engaged with the latching base 32 by using the latching jaws 22 so that the coupling force between the lever 20 and the housing 30 can be enhanced. Thus, the structural stability of the connector 1 can be improved.

In this embodiment, the latching jaw 22 has a shape extending continuously from side to side, but is not limited thereto. Therefore, it can be applied to the shape of the latching jaw 22 without limitation as long as it can be engaged with the latching bar 32 of the housing 30. Therefore, the latching jaw 22 can have a shape extending discontinuously from side to side, and the length extending toward the rear surface can also be non-uniform.

In this embodiment, since the lever 20 can rotate at a predetermined angle as described above, the latching jaw 22 can limit the rotational motion of the lever 20 to a certain angle. That is, when the engaging protrusion 22 and the engaging base 32 engage with each other, the lever 20 is further restricted from rotating in the downward direction. Consequently, the rotational movement of the lever 20 is limited to a certain angle.

The lever 20 may include a first fastening portion 25 on the front surface corresponding to the direction in which the terminal 40 is inserted. The first fastening part 25 may include an insertion groove, and the second fastening part 36 may be inserted into the insertion hose. That is, the first fastening part 25 can be fastened to the second fastening part 36 in such a manner as to cover the upper surface and the left and right sides of the second fastening part. By doing so, the lever 20 and the housing 30 can be structurally and strongly coupled, and thus the structural stability of the connector 1 can be improved.

The lever 20 and the housing 30 are coupled through the insertion of the second fastening portion 36 into the insertion groove included in the first fastening portion 25. However, It is not. Therefore, the configuration to be inserted and the configuration to be inserted may be opposite to those described above.

The lever 20 may include a coupling hole 24h on the right and left sides. The engaging hole 24h may be disposed adjacent to the front surface of the lever 20 in front of the rear surface thereof. The lever 20 can be fastened to the engaging projection 34 of the housing 30 through the engaging hole 24h. The engaging hole 24h can contact the outer wall of the left and right side walls of the housing 30. The engaging hole 24h may be annular and may be fastened to the engaging projection 34 by a method in which the engaging hole 24h is inserted into the engaging projection 34. [

In the present embodiment, the coupling manner through the annular coupling hole 24h and the projection-like coupling projection 34 has been described, but the present invention is not limited thereto. Therefore, the present invention can be applied without limitation as long as a part of the lever 20 can be structurally coupled to the outer surface of the housing 30.

The terminal 40 can be disposed inside the housing 30, and a part thereof can be disposed in the cable fixing portion 35. The terminal 40 may be a conductive metal capable of transmitting an electrical signal. The terminal 40 may include a plurality of connection terminals, each of which has a length extending in the first direction d1, and may be arranged in parallel with each other. One side of the terminal 40 may be electrically connected to a terminal included in the female connector inserted into the rear portion of the housing 30. For example, one side of the terminal 40 may be electrically connected in a manner that it is partially inserted into the terminal of the female connector. However, the present invention is not limited thereto.

Further, in the present embodiment, the terminal 40 is shown as including four connection terminals, but is not limited thereto. Thus, the terminal 40 may include a varying number of connection terminals depending on the requirements of the connector.

The flexible cable 10 can be inserted between the terminal 40 and the housing 30. [ At this time, the lever 20 can press the terminal 40 to connect the flexible cable 10 and the terminal 40. [ This will be described in detail with reference to Figs. 4A to 4E.

4A to 4E are cross-sectional views for explaining connection between a flexible cable and a terminal through a lever in a connector for a flexible cable according to an embodiment of the present invention. For the sake of explanation, the lever 20, the flexible cable 10 and the terminal 40 have been schematically represented. Therefore, the connector for a flexible cable according to an embodiment of the present invention is not limited to the illustrated form.

Referring to FIG. 4A, first, the lever 20 rotates with reference to the above-mentioned rotation axis, and the front surface of the lever 20 is arranged to face upward and the rear surface to face downward.

4B, the flexible cable 10 may be disposed on the housing 30. [0054] FIG. The flexible cable 10 includes a release preventing groove 13h on the side surface, as shown in the figure.

Referring to FIGS. 4C and 4D, the release preventing grooves 13h included in the flexible cable 10 and the release preventing jaws 33 of the housing 30 are engaged. That is, the release preventing tuck 33 is disposed in the release preventing groove 13h, so that the movement of the flexible cable 10 can be restricted and the connection holding force with the terminal 40 can be improved.

4E, the lever 20 rotates so as to directly press the terminal 40 to fix the connection between the terminal 40 and the flexible cable 10.

In the present invention, the connection between the terminal 40 and the flexible cable 10 can be performed quickly and easily by pressing the lever 20. Therefore, the connector for a flexible cable according to the present invention can easily realize a firm binding structure between the terminal 40 and the flexible cable 10 by pressing the lever 20.
