Description

Technical Field

[0001] The present invention relates to connection device technology, and particularly to a flexible cable connector and an electronic device. Background Art

[0002] A flexible cable connector is a commonly used component in electronic devices. Through the flexible cable connector, the flexible cable can be conveniently connected to a circuit board.

[0003] The existing flexible cable connector includes a base. The base is provided with a receiving portion and connection terminals. There are multiple connection terminals, and the multiple connection terminals are arranged at intervals along a straight line direction on the base. The receiving portion is used to receive the connection end of the flexible cable, so that the contacts of the connection end of the flexible cable are in contact with the connection terminals, realizing the electrical connection between the flexible cable connector and the flexible cable.

[0004] Since the base is usually a plastic part, it is necessary to keep a certain distance between adjacent two connection terminals, so that the part of the base located between adjacent two connection terminals has sufficient width, thereby ensuring the structural strength of the base. This results in that the connection terminals cannot be arranged closely, which is not conducive to the miniaturization of the flexible cable connector. Summary of the Invention

[0005] The present invention provides a flexible cable connector and an electronic device to facilitate the miniaturization of the product.

[0006] On the one hand, the present invention provides a flexible cable connector, including a base and connection terminals. A first connection portion, a second connection portion and a receiving portion are formed on the base. The first connection portion and the second connection portion are arranged at intervals along the length direction of the base. The receiving portion is used to receive the connection end of the flexible cable. The connection terminals include a first connection terminal and a second connection terminal. The first connection terminal is connected to the first connection portion, and the second connection terminal is connected to the second connection portion. There are multiple first connection terminals and multiple second connection terminals. The first connection terminals and the second connection terminals are arranged alternately in sequence along the width direction of the base. The connection terminals can be in contact with the contacts of the connection end of the flexible cable when the connection end of the flexible cable enters the receiving portion. A third connection portion is used to connect to a circuit board, so that the base and the circuit board are relatively positioned.

[0007] The flexible cable connector in an implementable embodiment further includes a cover plate. A buckle is provided on the cover plate, and the buckle is formed with a guiding surface and a clamping surface. The first end of the cover plate is connected to the base and cooperates with the base to form a socket. The axis of the socket extends along the length direction of the base. The socket is for the connection end of the flexible cable to be inserted and enter the accommodating portion. The connection terminal can be in contact with the contacts of the connection end of the flexible cable when the connection end of the flexible cable enters the accommodating portion. The second end of the cover plate can move relative to the base to reach an open state and a buckled state. The guiding surface can be in contact with and slide relative to the end of the connection end of the flexible cable inserted from the socket when the second end of the cover plate is in the buckled state, so that the buckle can cross over the end of the connection end of the flexible cable and snap into the bayonet of the connection end of the flexible cable. The clamping surface can be clamped with the bayonet when the buckle snaps into the bayonet to at least restrict the movement of the connection end of the flexible cable relative to the base along the axial direction of the socket. The buckle can release the state of being clamped with the bayonet of the connection end of the flexible cable when the second end of the cover plate is in the open state.

[0008] In the flexible cable connector in an implementable embodiment, the first connection terminal includes a first contact, and the second connection terminal includes a second contact. The first contact and the second contact can be in contact with the contacts of the connection end of the flexible cable when the connection end of the flexible cable enters the accommodating portion. A plurality of the first contacts are arranged in a first straight line in the width direction of the base, and a plurality of the second contacts are arranged in a second straight line in the width direction of the base. The first straight line and the second straight line are parallel and are spaced apart in the axial direction of the socket. The width direction of the cover plate is consistent with the width direction of the base. A first relief hole and a second relief hole are formed on the cover plate. The first relief hole can correspond to the position of the first contact when the second end of the cover plate is in the buckled state, and the first contact can extend into the first relief hole when in contact with the connection end of the flexible cable. The second relief hole can correspond to the position of the second contact when the second end of the cover plate is in the buckled state, and the second contact can extend into the second relief hole when in contact with the connection end of the flexible cable. A plurality of the first relief holes are arranged in a third straight line in the width direction of the cover plate, and a plurality of the second relief holes are arranged in a fourth straight line in the width direction of the base. The third straight line and the fourth straight line are parallel and are spaced apart in the length direction of the cover plate.

[0009] In the flexible cable connector in an implementable embodiment, rotating shafts are provided on both sides of the first end of the cover plate. The width direction of the cover plate is perpendicular to the axial direction of the socket. The rotating shafts are arranged along the width direction of the cover plate. The cover plate is rotatably connected to the base through the rotating shafts. The cover plate can rotate relative to the base with the rotating shafts as the center, so that the second end of the cover plate reaches the open state and the buckled state.

[0010] In the flexible cable connector in an implementable embodiment, it further includes a metal part. The metal part is connected to the base. The metal part and the base cooperate to form a bearing part. The rotating shaft is arranged in the bearing part so that the cover plate is rotatably connected to the base.

[0011] In the flexible cable connector in an implementable embodiment, the metal part includes a limiting side plate and a limiting top plate. The limiting side plate and the limiting top plate cooperate with the base to form the bearing part. The limiting side plate can be in contact with the rotating shaft to limit the rotating shaft from moving away from the base along the axial direction of the socket. The limiting top plate can be in contact with the rotating shaft to limit the rotating shaft from moving away from the base along the height direction of the base.

[0012] In the flexible cable connector in an implementable embodiment, the metal part further includes a plug-in board and a clamping board. The first end of the plug-in board is connected to the limiting top plate. The second end of the plug-in board is connected to the clamping board. The limiting top plate is connected to the limiting side plate. The plug-in board and the limiting top plate form a first set angle. The plug-in board and the clamping board form a second set angle. The limiting top plate and the limiting side plate form a third set angle. A first limiting part is formed on the top surface of the base. A second limiting part is formed on the bottom surface of the base. A slot is provided on the end surface of the base. The plug-in board is inserted into the slot. The limiting top plate is in contact with the first limiting part and the clamping board is in contact with the second limiting part to limit the metal part from moving relative to the base along the height direction of the base.

[0013] In the flexible cable connector in an implementable embodiment, the first set angle, the second set angle, and the third set angle are all 90 degrees.

[0014] In the flexible cable connector in an implementable embodiment, the cover plate is a metal cover plate, the rotating shaft is a metal rotating shaft, the metal rotating shaft and the metal cover plate are of an integrally formed structure, the metal part is an integrally formed metal part, the limiting side plate and the limiting top plate are in contact with the metal rotating shaft, and the clamping board is used for welding with a circuit board to ground the metal cover plate.

[0015] In the flexible cable connector according to an implementable embodiment, the connection terminal includes a first elastic arm and a second elastic arm. The first elastic arm and the second elastic arm can cooperate to clamp the connection end of the flexible cable when the connection end of the flexible cable enters the accommodation part, and the first elastic arm can contact the contact of the connection end of the flexible cable, so that the connection terminal is electrically connected to the flexible cable.

[0016] In the flexible cable connector according to an implementable embodiment, the buckle includes an elastic rod and a chuck. The elastic rod is connected between the chuck and the cover plate. The elastic rod extends along the length direction of the cover plate. The width direction of the cover plate is perpendicular to the axial direction of the socket. The guiding surface is formed at the first end of the chuck, and the clamping surface is formed at the second end of the chuck.

[0017] In the flexible cable connector according to an implementable embodiment, the cover plate is provided with a detection window, and the detection window is used to expose the edge of the bayonet when the buckle is snapped into the bayonet.

[0018] In the flexible cable connector according to an implementable embodiment, the cover plate is a metal cover plate, the buckle is a metal buckle, and the metal buckle and the metal cover plate are of an integrally formed structure.

[0019] In the flexible cable connector according to an implementable embodiment, the base is a plastic base, and both the first connection terminal and the base and the second connection terminal and the base are connected by an insert molding technique.

[0020] On the other hand, the present invention provides an electronic device, including a circuit board and the flexible cable connector provided by the present invention. The third connection part is connected to the circuit board, and the connection terminal is electrically connected to the circuit board.

[0021] Based on the above, in the flexible cable connector provided by the present invention, since the base is usually a plastic part, the too small width of the base part between two adjacent first connection terminals and between two adjacent second connection terminals will affect the structural strength. Since the first connection terminals and the second connection terminals are arranged alternately in the width direction of the base in sequence, and the first connection terminal is connected to the first connection part and the second connection terminal is connected to the second connection part, thus, even when the distance between the first connection terminal and the second connection terminal is reduced, it is still possible to ensure that the base parts between two adjacent first connection terminals and between two adjacent second connection terminals have sufficient width, so that the distance between the first connection terminal and the second connection terminal can be reduced on the premise of ensuring the strength, which is beneficial to the miniaturization of the flexible cable connector.

[0042] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] Please refer to Figure 1 and Figure 2 The cable connector provided by the embodiment of the present invention includes a base 101 and a connecting terminal 103. The base 101 is formed with a first connecting portion 124, a second connecting portion 125 and a receiving portion 104. The first connecting portion 124 and the second connecting portion 125 are arranged at intervals along the length direction of the base 101. The receiving portion 104 is used to receive the connecting end 201 of the cable; the connecting terminal 103 includes a first connecting terminal 126 and a second connecting terminal 127. The first connecting terminal 126 is connected to the first connecting portion 124, and the second connecting terminal 127 is connected to the second connecting portion 125. There are multiple first connecting terminals 126 and second connecting terminals 127. The first connecting terminals 126 and the second connecting terminals 127 are arranged alternately in sequence along the width direction of the base 101. The connecting terminal 103 can contact the contact point of the connecting end 201 of the cable when the connecting end 201 of the cable enters the receiving portion 104. The third connecting portion is used to connect to the circuit board 301 so that the base 101 and the circuit board 301 are relatively positioned.

[0044] In the flat cable connector of this embodiment, since the base 101 is usually a plastic part, the width of the base 101 between two adjacent first connection terminals 126 and between two adjacent second connection terminals 127 is too small, which will affect the structural strength. Since the first connection terminals 126 and the second connection terminals 127 are arranged alternately in sequence along the width direction of the base 101, and the first connection terminals 126 are connected to the first connection part 124, and the second connection terminals 127 are connected to the second connection part 125, the base 101 between two adjacent first connection terminals 126 and between two adjacent second connection terminals 127 can still have a sufficient width when the spacing between the first connection terminals 126 and the second connection terminals 127 is reduced, so that the spacing between the first connection terminals 126 and the second connection terminals 127 can be reduced under the premise of ensuring strength, which is conducive to the miniaturization of the flat cable connector.

[0045] Please refer to Figure 3 and Figure 4 In this embodiment, the flexible cable connector further includes a cover plate 102. A buckle 105 is provided on the cover plate 102. The buckle 105 is formed with a guiding surface 106 and a holding surface 107. The first end of the cover plate 102 is connected to the base 101 and cooperates with the base 101 to form a socket 108. The axis of the socket 108 extends along the length direction of the base 101. The socket 108 is used for the connection end 201 of the flexible cable to be inserted and enter the accommodating portion 104. The connection terminal 103 can be in contact with the contact of the connection end 201 of the flexible cable when the connection end 201 of the flexible cable enters the accommodating portion 104. The second end of the cover plate 102 can move relative to the base 101 to reach an open state and a latched state. The guiding surface 106 can be in contact with and slide relative to the end of the connection end 201 of the flexible cable inserted from the socket 108 when the second end of the cover plate 102 is in the latched state, so that the buckle 105 can cross over the end of the connection end 201 of the flexible cable and be snapped into the bayonet 202 of the connection end 201 of the flexible cable. The holding surface 107 can be latched with the bayonet 202 when the buckle 105 is snapped into the bayonet 202, so as to at least restrict the movement of the connection end 201 of the flexible cable along the axial direction of the socket 108 relative to the base 101. The buckle 105 can release the state of being latched with the bayonet 202 of the connection end 201 of the flexible cable when the second end of the cover plate 102 is in the open state.

[0046] In the flexible cable connector of this embodiment, during use, the base 101 can be connected to the circuit board 301 through the third connection part, and the connection terminal 103 is electrically connected to the circuit board 301. When it is necessary to connect the flexible cable, with the second end of the cover plate 102 in the buckled state, the connection end 201 of the flexible cable can be directly inserted into the accommodating part 104 from the socket 108. During the process of inserting the connection end 201 of the flexible cable into the socket 108, the guiding surface 106 of the buckle 105 will contact and slide relative to the end of the connection end 201 of the flexible cable. Through the guiding action of the guiding surface 106, the buckle 105 can cross over the end of the connection end 201 of the flexible cable and snap into the bayonet 202 of the connection end 201 of the flexible cable, so that the clamping surface 107 can be clamped with the bayonet 202 to at least restrict the movement of the connection end 201 of the flexible cable along the axial direction of the socket 108 relative to the base 101, preventing the connection end 201 of the flexible cable from withdrawing from the socket 108. At the same time, the connection terminal 103 contacts and is electrically connected to the contact of the connection end 201 of the flexible cable, thereby realizing the electrical connection between the flexible cable and the circuit board 301. When it is necessary to remove the flexible cable, the second end of the cover plate 102 can be moved relative to the base 101 to reach the open state. At this time, the state in which the buckle 105 is clamped with the bayonet 202 of the connection end 201 of the flexible cable can be released, so that the connection end 201 of the flexible cable can be conveniently withdrawn from the socket 108, and the electrical connection between the flexible cable and the circuit board 301 is released. Thus, when the flexible cable connector connects the flexible cable, it is not necessary to open the second end of the cover plate 102, which simplifies the operation process, improves the convenience of using the flexible cable connector, and is more conducive to realizing the automatic disassembly and assembly operation of the flexible cable connector and the flexible cable through automated equipment. And in the state where the connection end 201 of the flexible cable is inserted into the accommodating part 104 from the socket 108 and the bayonet 202 is clamped with the buckle 105, when the flexible cable is subjected to an upward pulling force, the flexible cable will contact the edge of the socket 108 and apply a force to the edge of the socket 108. Since the first end of the cover plate 102 cannot be opened, the cover plate 102 will not be lifted, thereby improving the reliability of using the flexible cable connector. In addition, the structure of the buckle 105 is simple, which is conducive to reducing the height of the flexible cable connector, thereby facilitating the miniaturization of the flexible cable connector.

[0047] In this embodiment, the first connection terminal 126 includes a first contact 128, and the second connection terminal 127 includes a second contact 129. The first contact 128 and the second contact 129 can be in contact with the contacts of the connection end 201 of the flexible cable when the connection end 201 of the flexible cable enters the receiving portion 104. The plurality of first contacts 128 are arranged along a first straight line in the width direction of the base 101, and the plurality of second contacts 129 are arranged along a second straight line in the width direction of the base 101. The first straight line and the second straight line are parallel and are spaced apart in the axial direction of the socket 108. The width direction of the cover plate 102 is consistent with the width direction of the base 101. The cover plate 102 is formed with a first relief hole 130 and a second relief hole 131. The first relief hole 130 can correspond to the position of the first contact 128 when the second end of the cover plate 102 is in the buckled state. The first contact 128 can extend into the first relief hole 130 when in contact with the connection end 201 of the flexible cable. The second relief hole 131 can correspond to the position of the second contact 129 when the second end of the cover plate 102 is in the buckled state. The second contact 129 can extend into the second relief hole 131 when in contact with the connection end 201 of the flexible cable. The plurality of first relief holes 130 are arranged along a third straight line in the width direction of the cover plate 102, and the plurality of second relief holes 131 are arranged along a fourth straight line in the width direction of the base 101. The third straight line and the fourth straight line are parallel and are spaced apart in the length direction of the cover plate 102.

[0048] Thus, when the connection end 201 of the flexible cable enters the receiving portion 104 and contacts the first contact 128 and the second contact 129, a force will be applied to the first contact 128 and the second contact 129, causing the first contact 128 and the second contact 129 to move toward the cover plate 102 and extend into the first relief hole 130 and the second relief hole 131 respectively. By providing the relief holes, in the state where the cover plate 102 is buckled with the base 101, even if the distance between the cover plate 102 and the first contact 128 and the second contact 129 is reduced, the cover plate 102 will not interfere with the movement of the first contact 128 and the second contact 129, which is beneficial to reducing the height of the flexible cable connector and thus beneficial to realizing the miniaturization of the flexible cable connector.

[0049] In this embodiment, rotating shafts 109 are provided on both sides of the first end of the cover plate 102. The width direction of the cover plate 102 is perpendicular to the axial direction of the socket 108. The rotating shafts 109 are arranged along the width direction of the cover plate 102. The cover plate 102 is rotatably connected to the base 101 through the rotating shafts 109. The cover plate 102 can rotate relative to the base 101 with the rotating shafts 109 as the center, so that the second end of the cover plate 102 reaches the open state and the buckled state. By rotating the cover plate 102 relative to the base 101 with the rotating shafts 109 as the center, the second end of the cover plate 102 can reach the open state and the buckled state. The operation is simple and convenient. In addition, both sides of the first end of the cover plate 102 are rotatably connected to the base 101 through the rotating shafts 109, and the structural stability is good. Of course, the cover plate 102 can also be made of elastic, flexible and other materials, so that the second end of the cover plate 102 can move relative to the base 101 when the first end of the cover plate 102 is fixedly connected to the base 101.

[0050] Please refer to Figure 5 and Figure 6 , in this embodiment, the flexible cable connector further includes a metal part 110. The metal part 110 is connected to the base 101. The metal part 110 and the base 101 cooperate to form a bearing part 111. The rotating shaft 109 is arranged in the bearing part 111 so that the cover plate 102 is rotatably connected to the base 101. Since the metal part 110 is adopted, the strength of the bearing part 111 can be improved, and further the stability of the connection between the cover plate 102 and the base 101 is improved.

[0051] In this embodiment, the metal part 110 includes a limiting side plate 112 and a limiting top plate 113. The limiting side plate 112 and the limiting top plate 113 cooperate with the base 101 to form a bearing part 111. The limiting side plate 112 can contact the rotating shaft 109 to limit the rotating shaft 109 from moving away from the base 101 along the axial direction of the socket 108. The limiting top plate 113 can contact the rotating shaft 109 to limit the rotating shaft 109 from moving away from the base 101 along the height direction of the base 101. Thus, the metal part 110 can limit the movement of the rotating shaft 109 in two directions, thereby further improving the stability of the connection between the cover plate 102 and the base 101.

[0052] In this embodiment, the metal part 110 further includes a plug-in board 114 and a clamping board 115. The first end of the plug-in board 114 is connected to the limit top plate 113, the second end of the plug-in board 114 is connected to the clamping board 115, the limit top plate 113 is connected to the limit side plate 112, the plug-in board 114 forms a first set angle with the limit top plate 113, the plug-in board 114 forms a second set angle with the clamping board 115, and the limit top plate 113 forms a third set angle with the limit side plate 112. A first limit portion 116 is formed on the top surface of the base 101, a second limit portion 117 is formed on the bottom surface of the base 101, and a slot 118 is provided on the end surface of the base 101. The plug-in board 114 is inserted into the slot 118, and the limit top plate 113 is in contact with the first limit portion 116 and the clamping board 115 is in contact with the second limit portion 117 to limit the movement of the metal part 110 relative to the base 101 in the height direction of the base 101. Thus, during the assembly process of the flexible cable connector, the cover plate 102 can be pre-assembled on the base 101 first, and the rotating shaft 109 is located at the position corresponding to the bearing portion 111. Then, the plug-in board 114 is inserted into the slot 118. At this time, the limit top plate 113 is in contact with the first limit portion 116 and the clamping board 115 is in contact with the second limit portion 117, thereby realizing the installation of the metal part 110, and the rotating shaft 109 is restricted within the bearing portion 111 formed by the cooperation of the limit top plate 113, the limit side plate 112 and the base 101. Thus, the assembly of the flexible cable connector is simple and convenient, and the structural strength is relatively high.

[0053] In this embodiment, the first set angle, the second set angle and the third set angle are all 90 degrees. Thus, it is beneficial to improve the structural strength of the metal part 110 and reduce the space occupied by the metal part 110.

[0054] In this embodiment, the cover plate 102 is a metal cover plate 102, the rotating shaft 109 is a metal rotating shaft 109, the metal rotating shaft 109 and the metal cover plate 102 are of an integrally formed structure, the metal part 110 is an integrally formed metal part 110, the limit side plate 112 and the limit top plate 113 are in contact with the metal rotating shaft 109, and the clamping board 115 is used for welding with the circuit board 301 to ground the metal cover plate 102. Since the cover plate 102 is a metal cover plate 102, it can shield electromagnetic interference and has relatively high strength, which is beneficial to reducing the thickness of the cover plate 102 and miniaturizing the flexible cable connector. Since the rotating shaft 109 is a metal rotating shaft 109 and the metal rotating shaft 109 is in contact with the metal part 110, after the clamping board 115 is welded to the circuit board 301, the metal cover plate 102 can be grounded, thereby improving the shielding effect.

[0055] Please refer to Figure 7, in this embodiment, the connection terminal 103 includes a first elastic arm 119 and a second elastic arm 120. The first elastic arm 119 and the second elastic arm 120 can cooperate to clamp the connection end 201 of the flexible cable when the connection end 201 of the flexible cable enters the accommodating portion 104, and the first elastic arm 119 can contact the contact of the connection end 201 of the flexible cable, so that the connection terminal 103 is electrically connected to the flexible cable. Since the first elastic arm 119 and the second elastic arm 120 can cooperate to clamp the connection end 201 of the flexible cable, the connection stability between the flexible cable connector and the connection end 201 of the flexible cable can be improved.

[0056] In this embodiment, the buckle 105 includes an elastic rod 121 and a clamping head 122. The elastic rod 121 is connected between the clamping head 122 and the cover plate 102. The elastic rod 121 extends along the length direction of the cover plate 102. The width direction of the cover plate 102 is perpendicular to the axial direction of the socket 108. The guiding surface 106 is formed at the first end of the clamping head 122, and the clamping surface 107 is formed at the second end of the clamping head 122. Thus, by providing the elastic rod 121, it is beneficial to improve the elastic deformation performance of the buckle 105, so that the buckle 105 can more easily cross the end of the connection end 201 of the flexible cable and enter the bayonet 202 of the connection end 201 of the flexible cable, making the operation more labor-saving.

[0057] In this embodiment, the cover plate 102 is provided with a detection window 123. The detection window 123 is used to expose the edge of the bayonet 202 when the buckle 105 is snapped into the bayonet 202. Thus, the detection device can obtain the image of the edge of the bayonet 202 through the detection window 123, and by measuring the distance between the edge of the bayonet 202 and the first end or the second end of the cover plate 102, it can be judged whether the connection end 201 of the flexible cable is connected in place, thereby improving the connection reliability between the flexible cable connector and the connection end 201 of the flexible cable.

[0058] In this embodiment, the cover plate 102 is a metal cover plate 102, and the buckle 105 is a metal buckle 105. The metal buckle 105 and the metal cover plate 102 are of an integrally formed structure. Thus, the metal cover plate 102 can shield electromagnetic interference and has a relatively high strength, which is beneficial to reducing the thickness of the cover plate 102 and miniaturizing the flexible cable connector. And the metal buckle 105 has a relatively high strength and good reliability. In addition, the metal buckle 105 and the metal cover plate 102 are of an integrally formed structure, which can be formed by cutting and bending a metal plate, with convenient processing and relatively high overall strength.

[0059] In this embodiment, the base 101 is a plastic base 101. The first connection terminal 126 and the base 101, as well as the second connection terminal 127 and the base 101, are both connected by an insert molding technology. Thus, the flexible cable connector is convenient to assemble, and it is beneficial to improve the connection strength between the first connection terminal 126, the second connection terminal 127 and the base 101.

[0060] An embodiment of the present invention provides an electronic device, including a circuit board 301 and the flexible cable connector described in any embodiment of the present invention. The third connection portion is connected to the circuit board 301, and the connection terminal 103 is electrically connected to the circuit board 301.

[0061] In the electronic device of this embodiment, since the base 101 is usually a plastic part, if the width of the base 101 between two adjacent first connection terminals 126 and between two adjacent second connection terminals 127 is too small, it will affect the structural strength. Since the first connection terminals 126 and the second connection terminals 127 are arranged alternately in sequence along the width direction of the base 101, and the first connection terminal 126 is connected to the first connection portion 124, and the second connection terminal 127 is connected to the second connection portion 125, thus, when the distance between the first connection terminal 126 and the second connection terminal 127 is reduced, it is still possible to ensure that the base 101 between two adjacent first connection terminals 126 and between two adjacent second connection terminals 127 has a sufficient width. Therefore, on the premise of ensuring the strength, the distance between the first connection terminal 126 and the second connection terminal 127 can be reduced, which is beneficial to the miniaturization of the flexible cable connector.
