[0046] The advantages and features of this invention, as well as the methods for achieving these advantages and features, will become apparent from the accompanying drawings and the embodiments described in detail below.

[0047] However, the present invention is not limited to the embodiments disclosed below, but is implemented in various forms that differ from each other, and the embodiments are provided only to make the disclosure of the present invention complete and to fully convey the scope of the invention to those skilled in the art to which the present invention pertains, and the present invention is defined only by the scope of the claims.

[0048] Furthermore, in describing this utility model, detailed descriptions of related prior art or other technologies will be omitted if it is determined that they may obscure the essence of this utility model.

[0049] The connector for the flexible cable according to the present invention will now be described with reference to the accompanying drawings.

[0050] Reference Figures 1 to 14 In the connector (10) for flexible cables according to the present invention, a flexible cable (not shown) can be inserted or pulled out.

[0051] exist Figure 1 The image shows the state in which the actuator (110) is closed to secure the flexible cable, and the actuator (110) can rotate during the insertion or removal of the flexible cable.

[0052] like Figures 1 to 14 As shown, the connector for flexible cables according to the present invention may include:

[0053] Housing (100), actuator (110), power supply terminal (130), detection terminal (140), signal terminal (150).

[0054] The housing (100) is for the flexible cable to be inserted in a first direction (X) and extends in a second direction (Y) that intersects the first direction (X).

[0055] The actuator (110) may be arranged on the housing (100) and may be coupled to the housing (100).

[0056] Additionally, the actuator (110) may include: a rotating shaft (111) extending in a second direction (Y); and a pressure-applying part (112) rotating about the rotating shaft (111) and applying pressure to the flexible cable.

[0057] The power terminal (130) may include: a first contact portion (131) disposed within the housing (100) and in contact with a flexible cable; a first extension portion (132) supporting the rotation shaft (111) of the actuator (110); and a first mounting portion (133) extending further from the first contact portion (131) in a first direction (X).

[0058] The detection terminal (140) may include: a second contact portion (141) disposed within the housing (100) and in contact with a flexible cable; a second extension portion (142) supporting the rotation shaft (111) of the actuator (110); and a second mounting portion (143) extending further from the second contact portion (141) in a first direction (X).

[0059] The signal terminal (150) can be formed in two forms and can be formed as follows: a first signal terminal (151) supporting the actuator (110) which rotates around the rotation axis (111) of the actuator (110); and a second signal terminal (155) supporting the rotation axis (111) of the actuator (110).

[0060] The first signal terminal (151) may include: a third contact portion (152) disposed within the housing (100) and in contact with a flexible cable; a third extension portion (153) supporting the actuator (110) which rotates about the rotation axis (111) of the actuator (110); and a third mounting portion (154) extending further from the third contact portion (152) in a first direction (X).

[0061] Additionally, the second signal terminal (155) may include: a third contact portion (156) disposed within the housing (100) and in contact with the flexible cable; a third extension portion (157) supporting the rotation shaft (111) of the actuator (110); and a third mounting portion (158) extending further from the third contact portion (156) in the first direction (X).

[0062] Therefore, multiple signal terminals can be arranged along the second direction (Y), and the first signal terminal (151) and the second signal terminal (155) can be arranged alternately to prevent the actuator (110) from falling off and accidentally opening the actuator (110).

[0063] That is, when the flexible cable is inserted, the actuator (110) is prevented from falling off due to the generation of reaction force, and when pressure is applied, the pressure position of the actuator (110) can be limited to prevent damage to the flexible cable.

[0064] In addition, such as Figures 7 to 11 As shown in (a) and (b), a ring-shaped support (132a) can be formed at the front end of the first extension (132) of the power terminal (130) to support the rotation shaft (111) of the actuator (110), and when a flexible cable is inserted, the actuator (110) can be fixed in the event of a reaction force, thereby strengthening the fastening.

[0065] In addition, a ring-shaped support (142a) can be formed at the front end of the second extension (142) of the detection terminal (140) to support the rotation shaft (111) of the actuator (110), and when a flexible cable is inserted, the actuator (110) can be fixed in the event of a reaction force, thereby strengthening the fastening.

[0066] In addition, a ring-shaped support (157a) can be formed at the front end of the third extension (157) of the second signal terminal (155) to support the rotation shaft (111) of the actuator (110), and when a flexible cable is inserted, the actuator (110) can be fixed in the event of a reaction force, thereby strengthening the fastening.

[0067] In addition, the detection terminal (140) is characterized in that it is located between the power terminal (130) and the signal terminal (150), thereby enabling the insertion of the flexible cable to be sensed.

[0068] Therefore, it can confirm whether the flexible cable is properly secured, thereby preventing damage caused by overcurrent.

[0069] Furthermore, the connector for flexible cables according to this utility model is characterized in that, as Figure 12 As shown, in the first direction (X), the length of the second contact portion (141) of the connector detection terminal (140) is shorter than the length of the first contact portion (131) of the connector power terminal (130) and the length of the third contact portion (152, 156) of the connector signal terminal (150).

[0070] Furthermore, the connector for flexible cables according to this utility model is characterized in that, when the flexible cable is inserted, it contacts the pattern of the flexible cable in the following order: the first contact portion (131) of the connector power terminal (130), the third contact portions (152, 156) of the first and second signal terminals (151, 155) of the connector signal terminal, and the second contact portion (141) of the connector detection terminal (140).

[0071] At this time, the first signal terminal (151) and the third contact portion (152, 156) of the second signal terminal (155) of the connector signal terminal (150) make contact simultaneously.

[0072] In addition, the raw material of the connector signal terminal (150) and the raw material of the connector detection terminal (140) can be formed from the same raw material.

[0073] That is, the first signal terminal (151), the second signal terminal (155), and the detection terminal (140) can be formed from the same raw materials.

[0074] Furthermore, in the connector for flexible cables according to the present invention, the contact points (131a) of the contact portion (131) of the connector power terminal (130) are formed as two, and the contact reliability can be improved by utilizing two-point contact.

[0075] In addition, the contact points of the connector signal terminal (150) can be formed in two.

[0076] That is, the contact portion (152) of the first signal terminal (151) has two contacts (152a, 152b), thereby improving contact reliability by utilizing two-point contact.

[0077] In addition, the contact portion (156) of the second signal terminal (155) has two contacts (156a, 156b), thereby improving contact reliability by utilizing two-point contact.

[0078] At this time, since the two contacts are arranged one in front of the other along the length of the contact portion, the flexible cable inserted into the flexible cable connector first contacts the contacts (152a, 156a) arranged in front of the two contacts, so foreign objects in the flexible cable can obviously be effectively removed.

[0079] In addition, the contact point (141a) of the contact portion (141) of the connector detection terminal (140) is formed in a manner that can confirm whether the flexible cable is properly secured.

[0080] When the contact portion (141) of the detection terminal (140) is formed into two contacts, such as a signal terminal or a power terminal, it can be judged as normal fastening even if only one of the two contacts is in contact. Therefore, it is preferable to form a single contact for accurate judgment.

[0081] like Figure 13 (a) to (d) and Figure 14 As shown, the feature is that the length of the second contact portion (141) of the connector detection terminal (140) is shorter than the length of the third contact portion (152, 156) of the first and second signal terminals (151, 155) of the connector signal terminal by G1.

[0082] Therefore, the connector for flexible cables according to the present invention is characterized in that, when the flexible cable is inserted, the connector contacts the pattern of the flexible cable in the following order: the third contact portion (152, 156) of the first and second signal terminals (151, 155) of the connector signal terminals, the first contact portion (131) of the connector power terminal (130), and the second contact portion (141) of the connector detection terminal (140).

[0083] This allows confirmation of whether the contact portion (141) of the detection terminal is in contact, thereby confirming whether the flexible cable is properly secured.

[0084] Furthermore, the connector for flexible cables according to this utility model is characterized in that, when the flexible cable is inserted, after the pattern of the flexible cable simultaneously contacts the third contact portion (152, 156) of the first and second signal terminals (151, 155) of the connector signal terminals and the first contact portion (131) of the connector power terminal (130), it contacts the second contact portion (141) of the connector detection terminal (140).

[0085] That is, after making contact with the signal terminals and power terminals, it is finally confirmed whether the contact part (141) of the detection terminal (140) is in contact, thereby confirming whether the flexible cable is properly secured.

[0086] According to the present invention, the connector for flexible cables is positioned so that the uppermost end of the contact point (141a) of the connector detection terminal (140) is located inside the center of the rotation axis (111) of the actuator (110) by D1, so that the flexible cable can finally contact the contact portion (141) of the detection terminal (140), thereby confirming whether the contact portion (141) of the detection terminal is in contact, and thus confirming whether the flexible cable is properly secured.

[0087] Therefore, according to this invention, it has the effect of saving space and preventing the actuator from falling off and accidentally opening compared to products with the same permissible current.

[0088] In addition, according to this utility model, the following effects are achieved: it can confirm whether the flexible cable is properly secured, thereby preventing damage caused by overcurrent, and the two-point contact design of the power terminal and the signal terminal can be used to improve the contact reliability.

[0089] Specific embodiments of the connector for flexible cables according to the present invention have been described to date, but it will be apparent that various modifications and implementations can be made without departing from the scope of the present invention.

[0090] Therefore, the scope of this utility model should not be limited to the described embodiments, but should be determined by the scope of the above claims and equivalent content.

[0091] That is, the above embodiments should be understood as illustrative and not limiting in all respects, and the scope of the present invention is shown by the scope of the above claims rather than by the detailed description, and should be interpreted as including the meaning and scope of the scope of the claims and all changes or modifications derived from their equivalent concepts within the scope of the present invention.
