Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to an FPC connector. Background Technology

[0002] Flexible Printed Circuit (FPC) connectors are commonly used in various portable electronic products, measuring instruments, and automotive electronics. They are primarily used in conjunction with FPC flexible printed circuit boards to transmit signals. Currently, FPC connectors generally consist of a plastic insulating body, an upper row of terminals, and a lower row of terminals. The upper row of terminals is located above the lower row and spaced apart to form electrical isolation. The FPC is inserted between the upper and lower rows of terminals. Because the FPC has flexible mating ends, misalignment can easily occur, which is detrimental to improving insertion efficiency and can lead to loosening during actual use. Utility Model Content

[0016] Optionally, the first clamping arm and the second clamping arm each include a free end and a connecting end connected to the main body, and the conductive terminal further includes two first contact arms respectively connected to the free ends of the first clamping arm and the second clamping arm.

Detailed Implementation

[0039] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0040] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0042] like Figures 1 to 16 As shown, it is an FPC connector 100 according to an embodiment of this application.

[0043] like Figures 1 to 5 As shown, the FPC connector 100 includes a first insulator 11, a second insulator 12, and a conductive terminal module, the conductive terminal module including a plurality of conductive terminals 13.

[0044] The conductive terminal module is fixed to the first insulator 11, and each conductive terminal 13 is fixed to the first insulator 11. The conductive terminal 13 includes a first clamping arm 131 and a second clamping arm 132 arranged opposite to each other in the clamping direction, a main body portion 133 connecting the first clamping arm 131 and the second clamping arm 132, a welding portion 134 connected to the main body portion 133, and a plurality of contact portions 135. The welding portion 134 can extend out of the first insulator 11 and is used to connect to the PCB (Printed Circuit Board) 30.

[0045] The first clamping arm 131 and the second clamping arm 132 are both elastic arms. Along the clamping direction, a receiving gap 130 for accommodating the FPC 20 is formed between the first clamping arm 131 and the second clamping arm 132. At least one contact portion 135 is disposed on the side of the first clamping arm 131 facing the second clamping arm 132 and at least one contact portion 135 is disposed on the side of the second clamping arm 132 facing the first clamping arm 131. When the FPC 20 is clamped between the first clamping arm 131 and the second clamping arm 132, the contact portion 135 abuts against the FPC 20.

[0046] The FPC 20 is held in place by the second insulator 12, which can be inserted into or removed from the first insulator 11. When the second insulator 12 is inserted into the first insulator 11, the FPC 20 is inserted into the receiving gap 130 and clamped between the first clamping arm 131 and the second clamping arm 132. The contact portion 135 abuts against the FPC 20 to achieve electrical connection between the conductive terminal 13 and the FPC 20. The solder portion 134 can extend out of the first insulator 11 and is used to connect to the PCB board 30. Thus, the FPC 20 and the PCB board 30 are electrically connected through the conductive terminal 13.

[0047] For example, the FPC 20 is provided with a plurality of first conductive portions 21 arranged in sequence. The plurality of first conductive portions 21 can be provided one-to-one with a plurality of conductive terminals 13. The plurality of first conductive portions 21 can be provided only on one side of the FPC 20, for example, Figure 6As shown, a plurality of first conductive portions 21 are disposed on the side opposite to the second clamping arm 132. The first conductive portions 21 abut against at least one contact portion 135 on the second clamping arm 132 to achieve electrical connection. The side of the FPC 20 without the first conductive portions 21 abuts against at least one contact portion 135 on the first clamping arm 131. Those skilled in the art should understand that the plurality of first conductive portions 21 may also be disposed only on the side of the FPC 20 opposite to the first clamping arm 131, or the plurality of first conductive portions 21 may be disposed simultaneously on both sides of the FPC 20 in the clamping direction.

[0048] On the other hand, the contact portion 135 abuts against the FPC 20 to achieve stable clamping of the FPC 20. When the entire FPC connector 100 vibrates during use, the FPC 20 can be stably clamped by the elastic support provided by the first clamping arm 131 and the second clamping arm 132 respectively.

[0049] For example, the first clamping arm 131 is provided with two spaced-apart contact portions 135, and the second clamping arm 132 is provided with two spaced-apart contact portions 135.

[0050] In this embodiment, a first insulator 11 is used to hold a conductive terminal module containing a plurality of conductive terminals 13, and a second insulator 12 is used to hold an FPC 20. The second insulator 12 is inserted into the first insulator 11. The conductive terminals 13 include a first clamping arm 131 and a second clamping arm 132 arranged opposite to each other in the clamping direction, a contact portion 135 provided on the first clamping arm 131 and the second clamping arm 132, a main body portion 133 connecting the first clamping arm 131 and the second clamping arm 132, and a welding portion 134 connected to the main body portion 133. When the second insulator 12 is inserted into the first insulator 11, the FPC 20 is clamped between the first clamping arm 131 and the second clamping arm 132 and abuts against the contact portion 135. In this way, the second insulator 12 serves as a carrier for the FPC 20, and the FPC is completed by inserting the second insulator 12 into the first insulator 11. The insertion of FPC 20 improves insertion efficiency. Furthermore, the structure of the conductive terminals is improved. The first clamping arm 131 and the second clamping arm 132 are arranged opposite each other in the clamping direction, and the contact part 135 abuts against the FPC 20 to achieve balanced and stable contact. A set of conductive terminals is used to clamp the FPC 20. During use, since the first clamping arm 131 and the second clamping arm 132 provide the same elastic support to the two sides of the FPC 20 in the clamping direction, it is beneficial to improve the clamping stability of the FPC 20 and reduce the occurrence of loosening.

[0051] As one implementation method, such as Figure 4 and Figure 5As shown, the first clamping arm 131 includes a free end 1311 and a connecting end 1312 connected to the main body 133. The second clamping arm 132 includes a free end 1321 and a connecting end 1322 connected to the main body 133. The conductive terminal 13 further includes two first contact arms 136, one of which is connected to the free end 1311 of the first clamping arm 131, and the other is connected to the free end 1321 of the second clamping arm 132. Exemplarily, the first clamping arm 131 and the second clamping arm 132 can extend approximately along the insertion direction, and the two first contact arms 136 can extend approximately along the insertion direction.

[0052] like Figure 5 As shown, when the conductive terminal 13 is fixed to the first insulator 11, the main body 133 and the two first contact arms 136 can contact the first insulator 11 respectively, so as to further improve the clamping stability of the first clamping arm 131 and the second clamping arm 132 on the FPC20.

[0053] In some implementations, such as Figure 4 and Figure 5 As shown, the conductive terminal 13 also includes two second contact arms 137, one of which is connected to the connection end 1312 of the first clamping arm 131, and the other is connected to the connection end 1322 of the second clamping arm 132. Exemplarily, the two second contact arms 137 may extend generally along the insertion direction.

[0054] like Figure 5 As shown, when the conductive terminal 13 is fixed to the first insulator 11, the main body 133, the two first contact arms 136 and the two second contact arms 137 can respectively contact the first insulator 11. The first clamping arm 131 and the second clamping arm 132 are respectively suspended in the first insulator 11. When the entire FPC connector 100 vibrates during use, the first clamping arm 131 and the second clamping arm 132 can better undergo elastic deformation to provide elastic support, so as to further improve the clamping stability of the first clamping arm 131 and the second clamping arm 132 on the FPC 20.

[0055] As one implementation method, such as Figure 7 As shown, the FPC connector 100 also includes a Terminal Position Assurance (TPA) 14 installed on the second insulator 12 to ensure that the FPC 20 is correctly positioned in the second insulator 12, and also to provide secondary locking and protection for the FPC 20.

[0056] Specifically, please refer to Figure 8As shown, the position guarantee member 14 includes a fixing part 141 and two first snap-fit ​​parts 142, which are respectively formed at both ends of the fixing part 141 along a first direction. Exemplarily, in this embodiment, the insertion direction represents the direction in which the second insulator 12 is inserted into the first insulator 11, and also represents the direction in which the FPC 20 is inserted into the second insulator 12; the clamping direction is perpendicular to the insertion direction, and the first direction is perpendicular to both the clamping direction and the insertion direction. If the clamping direction extends along the Z-axis, the insertion direction can extend along the X-axis, and the first direction can extend along the Y-axis.

[0057] Please see Figure 3 and Figure 9 As shown, the second insulator 12 includes a first receiving cavity 121 extending through the second insulator 12 along the insertion direction, a second receiving cavity 122 for receiving the position guarantee member 14, and a through groove 123 formed in the bottom wall of the second receiving cavity 122. The FPC 20 is inserted through the first receiving cavity 121 along the insertion direction. The second receiving cavity 122 can be an open cavity. The through groove 123 communicates with the first receiving cavity 121. There can be two through grooves 123. The two through grooves 123 are respectively located at both ends of the bottom wall of the second receiving cavity 122 along the first direction. When the position guarantee member 14 is installed in the second receiving cavity 122, the two first snap-fit ​​parts 142 extend into the first receiving cavity 121 through the two through grooves 123 respectively. The first snap-fit ​​parts 142 pass through the through grooves 123 and abut against the FPC 20 to lock the two ends of the FPC 20 along the first direction.

[0058] Specifically, the FPC 20 has notches 22 at both ends along the first direction, and the two notches 22 are respectively provided with two first snap-fit ​​portions 142. Please refer to the following. Figure 8 As shown, the first snap-fit ​​portion 142 includes a first extension portion 1421 connected to the fixing portion 141 and a second extension portion 1422 connected to the first extension portion 1421. The first extension portion 1421 extends from the fixing portion 141 in a clamping direction (e.g., the Y-axis) away from the fixing portion 141, and the second extension portion 1422 extends from the end of the first extension portion 1421 away from the fixing portion 141 in a plugging direction.

[0059] like Figure 10 and Figure 11 As shown, after the FPC 20 is inserted through the first receiving cavity 121 along the insertion direction, the position guarantee 14 is placed in the initial position of the second receiving cavity 122. The first snap-fit ​​portion 142 extends into the first receiving cavity 121 through the through groove 123, and the second extension portion 1422 is located in the notch 22 of the FPC 20; as Figure 10 and Figure 11As shown, the position retainer 14 is slid from the initial position to the locked position along the insertion direction, and the second extension 1422 abuts against the FPC 20 to lock the FPC 20.

[0060] In this embodiment, the FPC 20 is locked by the first latching portion 142 of the position guarantee member 14, which provides a strong and balanced locking force. The FPC 20 is less likely to skew in the insertion direction and clamping direction, further improving the clamping stability of the FPC 20 and reducing the occurrence of loosening.

[0061] In some implementations, please refer to Figure 8 As shown, the position guarantee member 14 also includes two second latching portions 143, which are respectively formed at both ends of the fixing portion 141 along the first direction.

[0062] Accordingly, please refer to Figure 9 As shown, the second insulator 12 also includes an elastic snap-fit ​​arm 124 disposed on the side wall of the second receiving cavity 122; the number of elastic snap-fit ​​arms 124 can be two, and the two elastic snap-fit ​​arms 124 are respectively located at both ends of the second receiving cavity 122 along the first direction. When the position guarantee member 14 is installed in the second receiving cavity 122, the two second snap-fit ​​portions 143 are respectively snapped with the two elastic snap-fit ​​arms 124 to lock the two ends of the position guarantee member 14 along the first direction to the second insulator 12.

[0063] For details, please continue reading Figure 9 As shown, the resilient snap-fit ​​arm 124 includes a resilient main body arm 1241 disposed on the side wall of the second receiving cavity 122 and a snap-fit ​​protrusion 1242 disposed on the side of the resilient main body arm 1241 facing the position guarantee member 14. Figure 12 As shown, after the FPC 20 is inserted through the first receiving cavity 121 along the insertion direction, the position guarantee member 14 is placed in the initial position of the second receiving cavity 122, and the snap-fit ​​protrusion 1242 contacts the second snap-fit ​​part 143; as Figure 12 and Figure 13 As shown, during the process of sliding the position retainer 14 from the initial position to the locked position along the insertion direction, the elastic main body arm 1241 is pressed by the position retainer 14 in the first direction toward the side wall of the second receiving cavity 122. When the position retainer 14 is in the locked position, the elastic main body arm 1241 rebounds in the first direction away from the side wall of the second receiving cavity 122, and the snap-fit ​​protrusion 1242 snaps and fixes with the second snap-fit ​​part 143 to lock the position retainer 14 in the locked position, and the position retainer 14 cannot move in the insertion direction.

[0064] For example, when the position guarantor 14 is in the initial position, the outer contour of the snap protrusion 1242 facing the position guarantor 14 is adapted to the outer contour of the second snap portion 143 facing the elastic snap arm 124.

[0065] In this embodiment, the position guarantor 14 is locked in the locked position by the engagement of the second snap-fit ​​portion 143 of the position guarantor 14 with the elastic snap-fit ​​arm 124. The position guarantor 14 cannot move in the insertion direction, which further improves the clamping stability of the FPC 20 and reduces the occurrence of loosening.

[0066] In some implementations, such as Figure 8 and Figure 9 As shown, the position guarantee member 14 also includes at least one protrusion 144 provided on the fixing part 141, and the second insulator 12 also includes at least one notch 125 opened on the side wall of the second receiving cavity 122, the notch 125 being used to receive the protrusion 144.

[0067] like Figure 10 and Figure 11 As shown, during the process of sliding the position retainer 14 from the initial position to the locked position along the insertion direction, the protrusion 144 is inserted into the corresponding notch 125.

[0068] In this embodiment, the position guarantee 14 is locked in the locked position by the cooperation between the protrusion 144 of the position guarantee 14 and the notch 125 in the second insulator 12, which reduces the probability of the position guarantee 14 moving in the first direction, further improves the clamping stability of the FPC 20, and reduces the occurrence of loosening.

[0069] In some implementations, such as Figure 7 and Figure 8 As shown, the position guarantee 14 also includes two fixing blocks 145. The two fixing blocks 145 are respectively disposed at both ends of the fixing part 141 along the first direction. The fixing blocks 145 are respectively disposed on the side of the end of the fixing part 141 facing away from the bottom wall of the second receiving cavity 122 and on the side of the second snap-fit ​​part 143 facing away from the bottom wall of the second receiving cavity 122. When the position guarantee 14 slides from the initial position to the locked position along the insertion direction, the fixing blocks 145 abut against the side wall of the second receiving cavity 122 to better fix the position guarantee 14 in the second receiving cavity 122.

[0070] In some implementations, such as Figure 7 and Figure 9As shown, the second insulator 12 includes an insulating body 12a and clamping and fixing arms 12b disposed at both ends of the insulating body 12a along a first direction; a first receiving cavity 121 and a second receiving cavity 122 are respectively disposed on the insulating body 12a, and a position guarantee member 14 is installed on the insulating body 12a; the clamping and fixing arms 12b extend along the insertion direction, and the FPC 20 is clamped by the two clamping and fixing arms 12b along the first direction after passing through the first receiving cavity 121. A receiving groove 12c is provided on the side of the two clamping and fixing arms 12b that are close to each other along the first direction. The two edges of the FPC 20 in the first direction are respectively accommodated in the two receiving grooves 12c. After the second insulator 12 is inserted into the first insulator 11, the part of the FPC 20 located between the two clamping and fixing arms 12b is clamped by a plurality of conductive terminals 13.

[0071] In this embodiment, the two clamping and fixing arms 12b can better hold the FPC 20 on the second insulator 12, thereby further improving the clamping stability of the FPC 20.

[0072] As one implementation method, such as Figure 3 and Figure 14 As shown, the first insulator 11 includes a first end face 11a and a second end face 11b disposed opposite to each other in the insertion direction. The first insulator 11 includes a plurality of insertion slots 111 extending through the first end face 11a in the insertion direction and an insertion cavity 112 extending through the second end face 11b in the insertion direction. The insertion slots 111 are used to accommodate conductive terminals 13. The plurality of insertion slots 111 are arranged one-to-one with the plurality of conductive terminals 13. The plurality of insertion slots 111 are arranged sequentially at intervals in the first direction. The insertion cavity 112 is used to accommodate the second insulator 12. The conductive terminals 13 are inserted into the insertion slots 111 from the first end face 11a in the insertion direction, and the second insulator 12 is inserted into the first insulator 11 from the second end face 11b in the insertion direction.
