[0075] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] The connector for flexible cables according to the present invention will now be described with reference to the accompanying drawings.
[0080] Reference Figures 1 to 11 (a) to Figure 11 (d) In the connector (10) for flexible cables according to the present invention, a flexible cable (not shown) can be inserted or pulled out.
[0081] like Figures 1 to 11 (a) to Figure 11 As shown in (d), the connector for flexible cables according to the present invention may include a housing 100, an actuator 110, a power terminal 130, a detection terminal 140, and a signal terminal 150.
[0082] exist Figure 1 The image shows the state where 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.
[0083] The housing 100 is for the insertion of a flexible cable in a first direction X, and extends in a second direction Y, which intersects the first direction X.
[0084] The actuator 110 may be disposed on the housing 100 and may be coupled to the housing 100.
[0085] Additionally, the actuator 110 may include: a rotating shaft 111 extending in a second direction Y; and a pressurizing portion 112 that rotates about the rotating shaft 111 and applies pressure to the flexible cable.
[0086] The power terminal 130 may be disposed within the housing 100 and includes: a first contact portion 131 for contacting a flexible cable; a first extension portion 137 for supporting the rotation shaft 111 of the actuator 110; and a first mounting portion 138 for further extending from the first contact portion 131 in a first direction X.
[0087] The detection terminal 140 may be arranged within the housing 100 and includes: a second contact portion 141 for contacting a flexible cable; a second extension portion 147 for supporting the rotation shaft 111 of the actuator 110; and a second mounting portion 148 for further extending from the second contact portion 141 in a first direction X.
[0088] At this point, the detection terminal 140 is positioned spaced apart from the power terminal 130 along the outer side of the connector and can sense the insertion of the flexible cable.
[0089] In addition, the fixing part 120 is arranged in the housing and can be used to mount the housing to the substrate and fix it in place.
[0090] Furthermore, the connector for flexible cables according to this utility model is characterized in that the contact portion of the detection terminal 140, i.e., the second contact portion 141, is shorter in the first direction X than the contact portion of the power terminal 130, i.e., the first contact portion 131.
[0091] That is, such as Figure 8 As shown, the length L1 of the second contact portion 141 of the detection terminal 140 is shorter than the length L2 of the first contact portion 131 of the power terminal 130.
[0092] Furthermore, the connector for flexible cables according to this utility model is characterized in that, when the flexible cable is inserted, the pattern of the flexible cable contacts the second contact portion 141 of the detection terminal 140 after contacting the first contact portion 131 of the power terminal 130.
[0093] Additionally, the detection terminal 140 is located on the outermost sides of the housing 100 among the terminals arranged in the housing 100.
[0094] That is, 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 portions 152 and 156 of the connector signal terminals 151 and 155, the first contact portion 131 of the connector power terminal 130, and the second contact portion 141 of the connector detection terminal 140.
[0095] 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 portions 152 and 156 of the connector signal terminals 151 and 155 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.
[0096] That is, after making contact with the signal terminals and power terminals, it is finally confirmed whether the contact portion 141 of the detection terminal 140 is in contact, thereby confirming whether the flexible cable is properly secured.
[0097] Therefore, the flexible cable can finally come into contact with the contact portion 141 of the detection terminal 140, thereby confirming whether the contact portion 141 of the detection terminal has been contacted, and thus confirming whether the flexible cable is properly secured.
[0098] Therefore, it can confirm whether the flexible cable is properly secured, thereby preventing damage caused by overcurrent.
[0099] In addition, such as Figure 12 As shown, the connector for flexible cables according to the present invention is characterized in that the first extension 137 of the power terminal 130 is connected by the first contact portion 131 and the first connecting portion 132. The first extension 137 of the power terminal 130 has a first sub-bend portion 135 and a second sub-bend portion 136 extending upward from the first connecting portion 132 in a third direction intersecting the first direction and the second direction. The first extension 137 includes a first sub-extension portion 133 extending from the first sub-bend portion 135 in the first direction X and a second sub-extension portion 134 extending from the second sub-bend portion 136 in the first direction X.
[0100] In addition, the first contact portion 131 of the power terminal 130 has two contact points 131a.
[0101] In addition, such as Figure 13 As shown, the connector for flexible cables according to the present invention is characterized in that the second extension 147 of the detection terminal 140 is connected by the second contact portion 141 and the second connecting portion 142. The second extension 147 of the detection terminal 140 has a third sub-bend portion 145 and a fourth sub-bend portion 146 extending upward from the second connecting portion 122 in a third direction intersecting the first direction and the second direction. The second extension 147 includes a third sub-extension portion 143 extending from the third sub-bend portion 145 in the first direction X and a fourth sub-extension portion 144 extending from the fourth sub-bend portion 146 in the first direction X.
[0102] Therefore, the detection terminal 140 has the following shape: it is located on the outermost sides of the housing so as to sense whether it is abnormally tightened, and can prevent damage or deformation caused by external force due to abnormal tightening.
[0103] In addition, the second contact portion 141 of the detection terminal 140 has only one contact point 141a.
[0104] 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 determined that the connection is normal even if only one of the two contacts is in contact. Therefore, it is preferable to form a single contact for accurate determination.
[0105] In addition, such as Figure 14 (a) and Figure 14 As shown in (b), the signal terminal 150 can be formed in two forms and can be formed by: a first signal terminal 151, which supports the actuator 110 rotating around the rotation axis 111 of the actuator 110; and a second signal terminal 155, which supports the rotation axis 111 of the actuator 110.
[0106] The first signal terminal 151 may be arranged within the housing 100 and includes: a third contact portion 152 for contacting a flexible cable; a third extension portion 153 for supporting the actuator 110, which rotates around the rotation axis 111 of the actuator 110; and a third mounting portion 154 for further extending from the third contact portion 152 in a first direction X.
[0107] Additionally, the second signal terminal 155 may be arranged within the housing 100 and includes: a third contact portion 156 for contacting a flexible cable; a third extension portion 157 for supporting the rotation shaft 111 of the actuator 110; and a third mounting portion 158 for further extending from the third contact portion 156 in the first direction X.
[0108] In addition, the contact portion 152 of the first signal terminal 151 has two contacts 152a and 152b, thereby improving contact reliability by utilizing two-point contact, and the contact portion 156 of the second signal terminal 155 has two contacts 156a and 156b, thereby improving contact reliability by utilizing two-point contact.
[0109] In addition, 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 front contact 152a, 152b or 156a, 156b, so foreign objects in the flexible cable can obviously be effectively removed.
[0110] 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.
[0111] That is, when the flexible cable is inserted, the actuator 110 is prevented from falling off due to the reaction force generated, and when pressure is applied, the pressure position of the actuator 110 can be limited to prevent damage to the flexible cable.
[0112] In addition, ring-shaped support portions 133a and 134a can be formed at the front ends of the first sub-extension 133 and the second sub-extension 134 of the power terminal 130 to support the rotation shaft 111 of the actuator 110. When a flexible cable is inserted, the actuator 110 can be fixed in the event of a reaction force, thereby strengthening the fastening.
[0113] In addition, ring-shaped support portions 143a and 144a can be formed at the front ends of the third sub-extension 143 and the fourth sub-extension 144 of the detection terminal 140 to support the rotation shaft 111 of the actuator 110. When a flexible cable is inserted, the actuator 110 can be fixed in the event of a reaction force, thereby strengthening the fastening.
[0114] Additionally, a ring-shaped support portion 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.
[0115] in addition, Figure 15 This is a plan view of the connector for flexible cables according to the present invention in the state where the actuator is removed, and Figure 16 yes Figure 15 A magnified view of part C.
[0116] Reference Figure 15 and Figure 16 The connector for flexible cables according to the present invention is characterized in that the width W2 of the first contact portion 131 of the power terminal 130 in the second direction Y is larger than the width W1 of the second contact portion 141 of the detection terminal 140.
[0117] As a result, the following effects are achieved: the first contact portion 131 of the power terminal 130 is formed to be wide on both sides, thereby minimizing the effects of rotation, and two contact points are arranged in the width direction, thereby preventing poor contact due to foreign objects during repeated operation.
[0118] 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.
[0119] In addition, according to this utility model, the following effects can be achieved: the proper fastening of the flexible cable can be confirmed by the detection terminal, 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.
[0120] 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.
[0121] 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-described patent claims and the equivalent content of the scope of these patent claims.
[0122] That is, the above embodiments should be understood as illustrative and not limiting in all respects, and the scope of this utility model is shown by the scope of the above patent claims rather than by the detailed description, and should be interpreted as including the meaning and scope of the scope of the patent claims and all changes or modifications derived from their equivalent concepts within the scope of this utility model.
