[0067] Referring to FIG. 11, the terminal 120 may include a first part 121 and a second part 122 spaced apart from each other in a second direction perpendicular to a first direction in which the cable 2 is inserted, a third part 123 connecting the rear of the first part 121 and the rear of the second part 122, and a fourth part 124 (see FIG. 9) protruding downwardly from the rear of the third part 123. A space may be formed between the first part 121 and the second part 122. The space between the first part 121 and the second part 122 may be opened in a forward direction. The cable 2 may be inserted into the space between the first part 121 and the second part 122. A pivot shaft 125 may be coupled to the third part 123. The fourth part 124 may be a portion that comes into contact with the board 70 (see FIGS. 6 and 9). The fourth part 124 may be mounted on the board 70. The terminal 120 may be electrically connected to the board 70 through the fourth part 124.

[0068] The cam 130 may be positioned between the first part 121 and the second part 122. The cam 130 may be positioned closer to the first part 121 than to the second part 122. The cable 2 may be inserted between the cam 130 and the second part 122. The cam 130 may be rotated by coming into contact with the cable 2. The cam 130 may be rotated so that its outer surface may come into contact with the first part 121 of the terminal 120. When the cam 130 comes into contact, the terminal 120 may pivot upward, and a protrusion 1221 of the terminal 120 may come into contact with a conductor exposure portion 213 (see FIG. 15) of the cable 2.

[0069] The cam 130 may include a cam body 131 and a protrusion 132 protruding from the rotating body 131. The cam body 131 may be coupled to the rotational shaft 133. The rotational shaft 133 may extend in a third direction perpendicular to the first and second directions. The rotational shaft 133 may be parallel to the pivot shaft 125 (see FIGS. 7 and 9). The pivot shaft 125 may extend in the third direction. The cam body 131 may have a circular cross-section. The protrusion 132 may protrude from a portion of the cam body 131 in a radial direction of the cam body 131. The protrusion 132 may protrude in a tangential direction of the cam body 131. The protrusion 132 may protrude in a direction that is bent along the outer surface of the cam body 131. The protrusion 132 may include a first surface 1321 connected to the outer surface of the cam body 131, and a second surface 1322 connected to the outer surface of the cam body 131 and the first surface 1321. The first surface 1321 and the second surface 1322 of the protrusion 132 may be formed as a plane. Alternatively, the first surface 1321 and the second surface 1322 of the protrusion 132 may be formed as a curved surface. The first surface 1321 of the protrusion 132 may be referred to as a first curved surface 1321, and the second surface 1322 of the protrusion 132 may be referred to as a second curved surface 1322. The diameter of the protrusion 132 may become smaller as it gets farther away from the cam body 131. The protrusion 132 may have an edge shape including the first surface 1321 and the second surface 1322. The connection portion of the first surface 1321 and the second surface 1322 may be formed as an edge shape. The connection portion of the first surface 1321 and the second surface 1322 may form an edge.

[0070] A groove 1211 may be formed in the first part 121 of the terminal 120. The groove 1211 may be formed on a lower surface where the first part 121 faces the second part 122. The groove 1211 may have a reverse edge shape with respect to the edge shape of the protrusion 132. The groove 1211 may have a diameter that becomes smaller from the lower surface of the first part 121 to the upper surface of the first part 121. The groove 1211 may include a first surface 1212 and a second surface 1213. A connecting portion of the first surface 1212 and the second surface 1213 of the groove 1211 may form an edge. The first surface 1212 of the groove 1211 may be connected to the lower surface of the first part 121. The first surface 1212 of the groove 1211 may be formed to be inclined with respect to the lower surface of the first part 121. The second surface 1213 of the groove 1211 may be connected to the lower surface of the first part 121. The second surface 1213 of the groove 1211 may be formed to be inclined with respect to the lower surface of the first part 121. The first surface 1212 of the groove 1211 may be provided as an inclined surface having a gentler slope than the second surface 1213 of the groove 1211. The lower surface of the first part 121 and the first surface 1212 of the groove 1211 may form a first angle. The lower surface of the first part 121 and the second surface 1213 of the groove 1211 may form a second angle. The first angle may be greater than the second angle. For example, the first angle may be an obtuse angle, and the second angle may be an acute angle.

[0071] In the initial state where the cam 130 is not rotated, the cam body 131 may face the groove 1211 of the first part 121, and the protrusion 132 may face the third part 123. In the initial state where the cam 130 is not rotated, the second curved surface 1322 of the protrusion 132 may face the first part 121, and the first curved surface 1321 of the protrusion 132 may face the second part 122. In the initial state where the cam 130 is not rotated, the cam 130 may be positioned apart from the first part 121. The cam 130 may be rotated to be positioned at a position where the protrusion 132 comes into contact with the first part 121 (see FIG. 12).

[0072] A protrusion 1221 may be formed on the second part 122 of the terminal 120. The protrusion 1221 may protrude in a direction from the second part 122 toward the first part 121. The protrusion 1221 may be in contact with the cable 2 (see FIG. 13). The protrusion 1221 may be in contact with the conductor exposure portion 213 of the cable 2 (see FIGS. 13 and 15). In this case, the terminal 120 and the cable 2 may be electrically connected. The protrusion 1221 may include a plurality of protrusions 1221. For example, the protrusion 1221 may include two protrusions 1221.

[0073] Referring to FIGS. 12 and 13, the cam 130 may be rotated by the cable 2. The cam 130 may be rotated by coming into contact with the cable 2. The cam 130 may be rotated around the rotation shaft 133 by coming into contact with the cable 2 inserted in the first direction. At this time, the rotation direction of the cam 130 may be referred to as a first rotation direction. When the cam 130 is rotated, the edge of the protrusion 132 may come into contact with the first part 121. When the cam 130 is rotated, the edge of the protrusion 132 may come into contact with the first part 121 to lift the first part 121. When the protrusion 132 comes into contact with the first part 121, the terminal 120 may be rotated around the pivot shaft 125. When the first part 121 is lifted by the protrusion 132, the terminal 120 may be rotated around the pivot shaft 125. The rotation direction of the terminal 120 may be referred to as a second rotation direction. The first rotation direction and the second rotation direction may be an opposite direction. For example, the first rotation direction may be clockwise, and the second rotation direction may be counterclockwise.

[0074] The cable 2 may rotate the cam 130 while being inserted in the first direction. The cam 130 may be rotated to pressurize the cable 2 in the second direction perpendicular to the first direction. The cam 130 may be rotated to pressurize the cable 2 in the direction toward the second part 122. In this case, the cable 2 and the protrusion 1221 of the second part 122 may come into contact. As the first part 121 is lifted by the protrusion 132, the terminal 120 rotates around the pivot shaft 125, so that the second part 122 of the terminal 120 may rise, and the protrusion 1221 of the second part 122 may come into contact with the cable 2. The conductor exposure portion 213 (see FIG. 15) of the cable 2 may come into contact with the protrusion 1221 of the second part 122.

[0075] The protrusion 132 may be rotated to be caught in the groove 1211 of the first part 121. The groove 1211 of the first part 121 may restrict the rotation of the cam 130. The first surface 1212 of the groove 1211 may guide the protrusion 132 to the groove 1211. The second surface 1213 of the groove 1211 may be in contact with the protrusion 132 to restrict the rotation of the protrusion 132. When the protrusion 132 is caught in the groove 1211 of the first part 121, the fastening of the cable 2 and the connector 100 may be completed. Accordingly, the cable 2 may be fastened to the connector 100 with one motion of inserting the cable 2 into the connector 100. Since the cable 2 is simply fastened with one motion, the work speed may be increased. In addition, an actuator that flips the housing 110 in a forward or rearward direction may not be required to fasten the cable 2 to the connector 100. Accordingly, it may not be necessary to secure a space for the operation of the actuator. Accordingly, the usable area of the board 70 may be increased.

[0076] Referring to FIG. 14, the cable 2 may be separated from the connector 100 through a pulling motion in a direction opposite to the first direction. At this time, the cam 130 may be rotated in a second rotation direction opposite to the first rotation direction, and the terminal 120 may be rotated in the first rotation direction. The cable 2 may be released from the connector 100 in one motion.

[0077] Referring to FIG. 15, the cable 2 may be a Flexible Flat Cable (FFC). The cable 2 may include a conductor layer 21 including a first surface 211 and a second surface 212, a first film 22 formed on the first surface 211 of the conductor layer 21, a second film 23 formed on the second surface 212 of the conductor layer 21, and a reinforcing plate 24 formed on the first film 22. The first and second films 22, 23 may be an insulating film. The second film 23 may be formed on at least a portion of the second surface 212 of the conductor layer 21, and may form a conductor exposure portion 213 on the second surface 212 of the conductor layer 21. The conductor exposure portion 213 may be inserted into the connector 100 and may come into contact with the protrusion 1221 of the terminal 120.

[0078] The cable 2 may include a conductor detachment prevention film 231 attached across the conductor exposure portion 213. The protrusion 1221 that comes into contact with the conductor exposure portion 213 of the cable 2 does not protrude into the inside of the terminal 120 until the cable 2 is inserted and the cam 130 is rotated, so that upon insertion of the cable 2, the damage and/or detachment of the conductor detachment prevention film 231 due to the protrusion 1221 may be prevented. Accordingly, it is possible to prevent a contact failure between the cable 2 and the connector 100 due to foreign matter.

[0079] The cable 2 may not include the conductor detachment prevention film attached across the conductor exposure portion 213. Since the protrusion 1221 that comes into contact with the conductor exposure portion 213 of the cable 2 does not protrude into the inside of the terminal 120 until the cable 2 is inserted and the cam 130 is rotated, the conductor of the cable 2 may not be scratched by the protrusion 1221 when the cable 2 is inserted. Accordingly, the conductor detachment prevention film may be omitted. Accordingly, the conductor detachment prevention film may not be damaged and/or detached, and the contact failure between the cable 2 and the connector 100 due to foreign matter can be prevented.

[0080] Referring to FIGS. 1 to 15, a connector 100 according to an aspect of the present disclosure may include: a housing 110; a terminal 120 pivotably installed inside the housing 110, the terminal 120 including a first part 121 extending long; a second part 122 facing the first part 121 and spaced apart from the first part 121; and a third part 123 connecting the first part 121 with the second part 122 and in which a pivot shaft 125 of the terminal 120 is positioned; and a cam 130 rotatably installed in the housing 110 and having an outer surface in contact with the first part 121 of the terminal 120 while rotating.

[0088] The cam 130 may have an outer surface that comes in contact with the first part 121 of the terminal 120 while rotating.

[0089] The second part 122 of the terminal 120 may include a protrusion 132 that protrudes toward the first part 121, wherein when the cam 130 comes in contact with the first part 121 of the terminal 120, the terminal 120 pivots upward around the pivot shaft 125, so that the protrusion 132 comes in contact with the cable 2.

[0090] The cam 130 may include: a cam body 131; and a protrusion 132 protruding in a radial direction of the cam body 131 from at least a portion of the cam body 131, wherein the protrusion 132 may come in contact with the first part 121 of the terminal 120 while rotating.

[0091] The first part 121 of the terminal 120 may include a groove 1211 formed at an inner surface of the first part 121, wherein the protrusion 132 of the cam 130 may be rotated and may be caught in the groove 1211.
