Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an FPC connector with CPA. Background Technology

[0002] Flexible printed circuit boards (FPCs) are increasingly used in automotive wiring harnesses. To ensure the stable application of FPC boards in automobiles, automotive-grade FPC connectors need to be fixed using CPA (connector secondary locking structure).

[0003] In existing automotive-grade FPC connectors, after the FPC board is inserted into the connector housing, the two ends of the FPC board are fixed by the FPC retainer. After the connector and the female component are mated, the CPA retainer is pushed into the locking position of the connector to complete the mating and locking of the male and female ends of the connector.

[0004] However, existing connectors have complex structures and cumbersome assembly processes, resulting in high production and assembly costs for FPC products.

[0005] Therefore, providing a connector with a simple structure and quick and reliable assembly has become an urgent problem to be solved in this field. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an FPC connector with CPA that is simple in structure, quick and reliable to assemble.

[0007] To achieve the above objectives, the present invention provides an FPC connector with CPA (Chip-Actuator), which mates with an FPC board and a mounting bracket, including a main plastic shell and an FPC fixing component, and also including a CPA fixing component.

[0009] The CPA fastener moves along the side end of the FPC fastener to form a first position and cooperates with the CPA pre-locking limiting structure to form a pre-locked state of the CPA fastener. The FPC fastener moves along the main plastic shell to form a first height and a second height. Through the cooperation of the FPC assembly structure and the FPC limiting structure, the FPC fastener forms a pre-locked state at the first height and is inserted into the FPC board. At the second height, the FPC fastener forms a final locked state and simultaneously limits the FPC board.

[0010] Furthermore, the central area of ​​the main plastic shell is provided with an FPC assembly groove for interlocking with the FPC board, and the two sides are respectively provided with an FPC board primary lock for interlocking with the FPC board. The two sides of the main plastic shell are also respectively provided with vertically distributed FPC fastener positioning grooves, horizontally distributed FPC fastener pre-locking steps and FPC fastener final locking steps arranged in parallel along the height direction.

[0011] Furthermore, the inner walls on both sides of the FPC fastener are respectively provided with limiting walls that are adapted to the positioning groove of the FPC fastener. The limiting walls are provided with openings. The bottom areas on both sides of the FPC fastener are provided with FPC fastener positioning steps that cooperate with the FPC fastener pre-locking step and the FPC fastener final locking step.

[0012] Furthermore, the FPC fastener positioning step and the FPC fastener pre-locking step cooperate to form the pre-locked state of the FPC fastener, and the opening is simultaneously horizontally aligned with the groove opening of the FPC assembly slot. The FPC fastener positioning step and the FPC fastener final locking step cooperate to form the final locking state of the FPC fastener, and the opening is simultaneously abutting against the groove wall of the FPC assembly slot.

[0013] Furthermore, the FPC board can be inserted into the FPC assembly slot through the opening. The FPC board has a pre-positioning slot and a fixing slot on both sides.

[0014] Furthermore, the outer wall of the side end of the FPC fastener is provided with a CPA mounting groove that mates with the CPA fastener. The side of the CPA mounting groove that mates with the FPC fastener forms a CPA sliding groove, and the other side is provided with a spring wall step. The two ends of the CPA mounting groove are respectively provided with positioning grooves.

[0015] Furthermore, the CPA fastener is adapted to the CPA mounting groove. One side of the CPA fastener that mates with the FPC fastener is provided with an assembly limiting block adapted to the CPA slide groove, and the other side is provided with a cantilever hook that is elastically connected.

[0042] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0043] Example 1

[0044] See Figure 1 The image shows an example of an FPC connector with CPA provided by this utility model.

[0045] As shown in the figure, the FPC connector with CPA in this example mates with the FPC board 4 and the counter 5, and mainly includes the main plastic shell 1, the FPC fastener 2 and the CPA fastener 3.

[0046] The side ends of the FPC fastener 2 are respectively provided with a CPA pre-locking limit structure and an FPC assembly structure. The main plastic shell 1 is provided with an FPC limit structure corresponding to the FPC assembly structure, and the hand part 5 is provided with a CPA final lock limit structure corresponding to the CPA pre-locking limit structure.

[0047] Furthermore, the CPA fastener 3 moves along the side end of the FPC fastener 2 to form a first position and cooperates with the CPA pre-locking limiting structure to form a pre-locked state of the CPA fastener 3. The FPC fastener 2 moves along the main plastic shell 1 to form a first height and a second height. Through the cooperation of the FPC assembly structure and the FPC limiting structure, the FPC fastener 2 is in a pre-locked state at the first height and is inserted into the FPC plate 4. At the second height, the FPC fastener 2 is in a final locked state and the FPC plate 4 is simultaneously limited. The CPA fastener 3 continues to move along the side end of the FPC fastener 2 to form a second position and cooperates with the CPA final locking limiting structure to form a final locked state of the CPA fastener 3. The structure is simple and the assembly is fast and reliable.

[0048] Combination Figure 2 The main plastic shell 1 has an FPC assembly slot 11 in the middle area that is inserted into the FPC board 4, and FPC board primary locks 12 in the two side areas respectively, which are used to elastically abut against the FPC board 4, so that the FPC board 4 can be inserted into the FPC assembly slot 11 and elastically snapped into the FPC board primary locks 12 to realize the assembly of the FPC board 4.

[0049] Preferably, the main plastic shell 1 has two layers of FPC assembly slots 11. Correspondingly, two sets of FPC board primary locks 12 are distributed on the top and bottom of the main plastic shell 1 and respectively cooperate with the two layers of FPC assembly slots 11, so that the main plastic shell 1 can place two layers of FPC boards 4 through the FPC assembly slots 11 and realize the assembly of the two layers of FPC boards 4 through the corresponding FPC board primary locks 12.

[0050] Furthermore, the two sides of the main plastic shell 1 are respectively provided with FPC fastener positioning groove 13, FPC fastener pre-locking step 14 and FPC fastener final locking step 15, so that the FPC fastener positioning groove 13, FPC fastener pre-locking step 14 and FPC fastener final locking step 15 cooperate with the FPC fastener 2 to form the pre-locking state and final locking state of the FPC fastener 2, and simultaneously realize the insertion and limiting of the FPC board 4.

[0051] Specifically, the FPC fastener positioning groove 13 is provided on both sides of the main plastic shell 1 and is vertically distributed. The FPC fastener pre-locking step 14 and the FPC fastener final locking step 15 are provided in the bottom area of ​​the main plastic shell 1, are horizontally distributed and arranged side by side along the height direction. The FPC fastener pre-locking step 14 and the FPC fastener final locking step 15 are respectively provided at the first height and the second height of the main plastic shell 1.

[0052] Combination Figure 3 and Figure 4 In conjunction with this, the inner walls on both sides of the FPC fastener 2 are respectively provided with limiting walls 21 that are adapted to the positioning groove 13 of the FPC fastener. The limiting walls 21 are provided with openings 22. The bottom area of ​​the inner walls on both sides of the FPC fastener 2 is also provided with FPC fastener positioning steps 23 that cooperate with the FPC fastener pre-locking step 14 and the FPC fastener final locking step 15.

[0053] In this way, the limiting wall 21 can be inserted into the FPC fastener positioning groove 13 from above the main plastic shell 1 along the height direction, move vertically along the FPC fastener positioning groove 13, and drive the FPC fastener positioning step 23 to move vertically along the side wall of the main plastic shell 1 simultaneously, forming a first height and a second height. Through the cooperation of the FPC fastener positioning step 23 and the FPC fastener pre-locking step 14, the FPC fastener 2 is pre-locked at the first height. At the same time, the opening 22 on the limiting wall 21 is horizontally aligned with the groove of the FPC assembly groove 11, reserving space for the insertion of the FPC board 4, so that the FPC fastener 2 can be inserted and cooperate with the FPC board 4. Correspondingly, through the cooperation of the FPC fastener positioning step 23 and the FPC fastener final locking step 15, the FPC fastener 2 is finally locked at the second height. At the same time, the opening 22 on the limiting wall 21 simultaneously abuts against the groove wall of the FPC assembly groove 11 to simultaneously limit the FPC board 4.

[0054] Combination Figure 3 and Figure 4Furthermore, the outer wall of the side end of the FPC fastener 2 is provided with a CPA mounting groove 24 that mates with the CPA fastener 3. A CPA sliding groove 25 is formed on the side of the CPA mounting groove 24 that mates with the FPC fastener 2, and the CPA mounting groove 24 and the CPA sliding groove 25 are connected so that the CPA fastener 3 can move along the side end of the FPC fastener 2 through the CPA sliding groove 25 and be accommodated in the CPA mounting groove 24.

[0055] Meanwhile, the other side of the CPA mounting groove 24 is provided with a spring wall step 26, and the two ends of the CPA mounting groove 24 are respectively provided with positioning grooves 27, so that the CPA fixing member 3 can move along the side end of the FPC fixing member 2 towards the CPA mounting groove 24 to form the first position. When it is in the first position, the spring wall step 26 and the positioning groove 27 cooperate with the CPA fixing member 3 to form the pre-locked state of the CPA fixing member 3.

[0056] Combination Figure 5 In conjunction with this, the CPA fastener 3 is adapted to the CPA mounting groove 24. The side of the CPA fastener 3 that mates with the FPC fastener 2 is provided with an assembly limiting block 31 adapted to the CPA slide groove 25, and the other side is provided with a cantilever hook 32 that is elastically connected. Furthermore, both ends of the CPA fastener 3 are provided with CPA fastener positioning steps 33 that mate with the positioning groove 27.

[0057] Combination Figure 6 and Figure 7 In this way, the CPA fastener 3 is pushed to move along the side end of the FPC fastener 2, the assembly limiting block 31 is inserted into the CPA slide groove 25, moves along the CPA slide groove 25 towards the CPA mounting groove 24, and drives the cantilever hook 32 and the CPA fastener positioning step 33 to move towards the CPA mounting groove 24 simultaneously.

[0058] When the cantilever hook 32 moves to the spring wall step 26, the CPA fixing member positioning step 33 moves synchronously to the positioning groove 27 to form the first position. Through the cooperation of the cantilever hook 32 and the spring wall step 26, the positioning groove 27 cooperates with the CPA fixing member positioning step 33 to initially limit the CPA fixing member 3 and form the pre-locked state of the CPA fixing member 3.

[0059] To ensure the pre-locking stability of the CPA fastener 3, the spring wall step 26 includes a first spring wall step 261 and a second spring wall step 262. The first spring wall step 261 and the second spring wall step 262 are vertically distributed and arranged side by side on the CPA mounting groove 24. The first spring wall step 261 is located close to the CPA fastener 3, and the second spring wall step 262 is located away from the CPA fastener 3. The first spring wall step 261 cooperates with the hook end 321 of the cantilever hook 32, and the second spring wall step 262 cooperates with the tail end 322 of the cantilever hook 32.

[0060] Correspondingly, the hook end 321 of the cantilever hook 32 forms an inclined hook that is adapted to the assembly and movement direction of the CPA fastener 3, so that the CPA fastener 3 moves along the side end of the FPC fastener 2. When the cantilever hook 32 moves to the spring wall step 26 and forms the first position, the cantilever hook 32 first engages with the first spring wall step 261, and the hook end 321 abuts against the first spring wall step 261. Since the cantilever hook 32 and the CPA fastener 3 are elastically connected, under the action of the elastic force of the cantilever hook 32 itself and the external pushing force on the CPA fastener 3, the hook end 321 moves along the first spring wall step 261 towards the CPA mounting groove 24, passes through the cavity at the side end of the first spring wall step 261, and locks the first spring wall step 261, and is placed between the first spring wall step 261 and the second spring wall step 262.

[0061] At this time, the second spring wall step 262 abuts against the tail end 322 of the cantilever hook 32, limiting the cantilever hook 32. Thus, with the cooperation of the first spring wall step 261 and the second spring wall step 262 with the cantilever hook 32, the CPA fastener 3 cannot continue to move towards the CPA mounting slot 24, thus limiting the CPA fastener 3.

[0062] Combination Figure 6 and Figure 7 Furthermore, the positioning grooves 27 are respectively disposed at the top and bottom of the CPA mounting groove 24, including a first positioning groove 271, a second positioning groove 272 and a third positioning groove 273. The first positioning groove 271, the second positioning groove 272 and the third positioning groove 273 are arranged side by side and have similar structures. The first positioning groove 271 is disposed close to the CPA fixing member 3, and the second positioning groove 272 and the third positioning groove 273 are disposed away from the CPA fixing member 3 in sequence. The first positioning groove 271 is configured in a right trapezoidal distribution, with the right angle side disposed close to the CPA fixing member 3 and the inclined side disposed away from the CPA fixing member. The second positioning groove 272 and the third positioning groove 273 are configured in an isosceles trapezoidal distribution with inclined sides on both sides.

[0063] Correspondingly, the CPA fixing member positioning steps 33 are respectively disposed at the top and bottom of the CAP fixing member 3, including a first positioning step 331 and a second positioning step 332 adapted to the positioning groove 27. The first positioning step 331 and the second positioning step 332 are distributed side by side and have similar structures. The first positioning step 331 is distributed close to the FPC fixing member 2 and is configured as an isosceles trapezoid with two inclined sides. The second positioning step 332 is distributed away from the FPC fixing member 2 and is configured as a right-angled trapezoid with the right-angled side away from the FPC fixing member 2 and the inclined side close to the FPC fixing member 2.

[0064] In this way, when the CPA fixing member 3 moves to the first position, the spring wall step 26 engages with the cantilever hook 32 to limit the CPA fixing member 3. At the same time, the first positioning step 331 and the second positioning step 332 move synchronously along the positioning groove 27. The first positioning step 331 is placed in the first positioning groove 271, and the first positioning groove 271 can limit the first positioning step 331. Meanwhile, the second positioning step 332 is placed in the second positioning groove 272, and the second positioning groove 272 can limit the second positioning step 332.

[0065] At this time, the first positioning groove 271 and the second positioning groove 272 form a pre-locking groove. The right-angled sides of the second positioning groove 272 and the second positioning step 332 cooperate to form a right-angle limit, so that the second positioning step 332 cannot move backward from the second positioning groove 272 to the CPA mounting groove 24, and cannot be pulled out. It can only move towards the CPA mounting groove 24 through the relative inclined surfaces, so that the CPA fastener 3 will not fall off from the FPC fastener 2.

[0066] Therefore, when the CPA fastener 3 is in the first position, the cantilever hook 32 and the spring wall step 26 cooperate, and the positioning groove 27 cooperates simultaneously with the CPA fastener positioning step 33 to limit the CPA fastener 3, forming a pre-locked state of the CPA fastener 3. This prevents the CPA fastener 3 from retracting and falling out of the FPC fastener 2, ensuring the pre-locking stability of the CPA fastener 3 and positioning the CPA fastener 3 in the FPC fastener 2.

[0067] To improve assembly efficiency, before the FPC fastener 2 is inserted into the main plastic shell 1, the FPC fastener 2 and the CPA fastener 3 are pre-assembled. This ensures that the CPA fastener 3 is positioned on the FPC fastener 2 and forms a pre-locked state before the FPC fastener 2 is inserted into the main plastic shell 1, so that the FPC fastener 2 and the CPA fastener 3 can be inserted into the main plastic shell 1 synchronously, which facilitates the insertion and limiting cooperation with the FPC board 4.

[0068] At this time, FPC fastener 2 and CPA fastener 3 are simultaneously inserted into the main plastic shell 1, so that FPC fastener 2 cooperates with the main plastic shell 1, forming a pre-locked state of FPC fastener 2 at the first height, and FPC board 4 can be inserted into the main plastic shell 1 and FPC fastener 2, and forming a final locked state of FPC fastener 2 at the second height, limiting and fixing FPC board 4, and ensuring that FPC board 4 is stably positioned.

[0069] Combination Figure 8In order to cooperate with the main plastic shell 1 and the FPC fastener 2, the FPC board 4 has parallel FPC board pre-positioning slots 41 and FPC board fixing slots 42 on both sides. The FPC board pre-positioning slots 41 are located on the side of the FPC board 4, close to the main plastic shell 1 and the FPC fastener 2. The FPC board fixing slots 42 are farther away from the main plastic shell 1 and the FPC fastener 2 than the FPC board pre-positioning slots 41, so that the FPC board 4 can simultaneously form an insertion fit and limit with the main plastic shell 1 and the FPC fastener 2 through the FPC board pre-positioning slots 41 and the FPC board fixing slots 42 during the process of inserting the FPC fastener 2 and the CPA fastener 3 into the main plastic shell 1.

[0070] Combination Figures 9 to 11 As an example, the FPC fastener 2 and the CPA fastener 3 are inserted into the main plastic shell 1 from above along the height direction. The limiting wall 21 of the FPC fastener 2 is inserted into the FPC fastener positioning groove 13 of the main plastic shell 1 and moves vertically along the FPC fastener positioning groove 13 to guide the movement direction of the FPC fastener 2 and prevent the movement of the FPC fastener 2 from causing deviation. At the same time, it drives the FPC fastener positioning step 23 to move vertically along the side wall of the main plastic shell 1.

[0071] Furthermore, the end of the FPC fastener positioning step 23 is provided with an inclined hook adapted to the assembly and movement direction of the FPC fastener 2. When the limiting barrier 21 moves vertically along the FPC fastener positioning groove 13, causing the FPC fastener positioning step 23 to move to the FPC fastener pre-locking step 14, a first height is formed, and the FPC fastener positioning step 23 will engage with the FPC fastener pre-locking step 14, initially limiting the FPC fastener 2 and forming the pre-locking state of the FPC fastener 2. Figure 10 As shown.

[0072] At this time, the opening 22 on the limiting barrier 21 is horizontally aligned with the slot of the FPC assembly slot 11, reserving space for the insertion of the FPC board 4. This allows the FPC board 4 to be inserted into the FPC assembly slot 11 through the opening 22 on both sides without interfering with the FPC fastener 2. Figure 11 As shown.

[0073] Combination Figure 12 and Figure 13To ensure the FPC board 4 is stably placed in the FPC assembly slot 11, the FPC board primary lock 12 is correspondingly provided with the FPC board pre-positioning slots 41 and FPC board fixing slots 42 on both sides of the FPC board 4, and forms a cantilever elastic connection with the main plastic shell 1. A board lock hook 121 is formed at the end of the FPC board primary lock 12, and the end face of the board lock hook 121 that mates with the FPC board 4 is configured as an inclined surface adapted to the insertion direction of the FPC board 4, so that when the FPC board 4 is inserted into the FPC assembly slot 11, the FPC board 4... The surface of the FPC board 4 abuts against the inclined surface of the board lock hook 121. As the FPC board 4 is continuously pushed, under the action of the pushing force of the FPC board 4 and the elastic force of the FPC board primary lock 12 itself, the FPC board 4 will pass over the bottom end of the board lock hook 121, so that the board lock hook 121 falls into the FPC board pre-positioning slot 41, limiting the FPC board 4. The FPC board 4 cannot move continuously, so that the FPC board 4 is inserted into the FPC assembly slot 11 and cooperates with the FPC board primary lock 12 to form the pre-positioning state of the FPC board 4.

[0074] Therefore, when the FPC fastener 2 forms the pre-locked state of the FPC fastener 2 at the first height, the FPC board 4 is inserted into the FPC assembly slot 11 through the opening 22, and the FPC board lock 12 is engaged in the FPC board pre-positioning slot 41, thus simultaneously forming the pre-positioning state of the FPC board 4.

[0075] At this time, the FPC board fixing slot 42 of the FPC board 4 is vertically aligned with the limiting barrier 21 and the FPC fastener positioning slot 13, such as Figure 12 As shown, when the limiting barrier 21 moves vertically along the FPC fixing positioning groove 13, the opening 22 will simultaneously abut against the groove wall of the FPC assembly groove 11. The limiting barrier 21 will fall into the FPC board fixing slot 42, preventing the FPC board 4 from retracting and falling out of the FPC assembly groove 11. This ensures that the FPC board 4 is completely fixed in the FPC assembly groove 11, forming a fixed state for the FPC board 4. Figure 14 and Figure 15 As shown.

[0076] Here, the opening 22 simultaneously abuts against the wall of the FPC assembly slot 11 and will not fall into the next layer of FPC assembly slot 11, so as to ensure that the limiting wall 21 can simultaneously fall into the FPC board fixing slot 42 of the two layers of FPC boards 4, and ensure the synchronous limiting and fixing of the two layers of FPC boards 4.

[0077] Combination Figure 14 and Figure 15Simultaneously, as the limiting barrier 21 moves vertically along the FPC fastener positioning groove 13, it will drive the FPC fastener positioning step 23 to move vertically in sync. This causes the inclined hook at the end of the FPC fastener positioning step 23 to disengage from the FPC fastener pre-locking step 14 and move vertically to the FPC fastener final locking step 15, forming a second height. The FPC fastener positioning step 23 then engages in the FPC fastener final locking step 15, limiting the FPC fastener 2 and forming the final locking state of the FPC fastener 2.

[0078] Therefore, when the FPC fastener 2 is in its final locked state at the second height, the limiting wall 21 is engaged in the FPC board fixing slot 42, and the FPC board 4 is simultaneously fixed.

[0079] The FPC fastener 2 thus formed can cooperate with the CPA fastener 3 and the main plastic shell 1 to ensure that the CPA fastener 3 moves along the side of the FPC fastener 2, forming a pre-locked state of the CPA fastener 3 in the first position, fixing the CPA fastener 3 to the FPC fastener 2. The FPC fastener 2 drives the CPA fastener 3 to be inserted into the main plastic shell 1 at the same time, forming a pre-locked state of the FPC fastener 2 at the first height, and simultaneously engaging with the FPC board 4 to ensure the stable placement of the FPC board 4. At the second height, the FPC fastener 2 forms a final locked state, simultaneously limiting and fixing the FPC board 4, thereby improving assembly efficiency and ensuring assembly reliability.

[0080] Combination Figure 16 In order to ensure that the FPC connector can be stably assembled with the counterpart 5, a main cavity 51 is formed in the counterpart 5 to accommodate the main plastic shell 1, the FPC fixing part 2 and the CPA fixing part 3, so that the main plastic shell 1, the FPC fixing part 2, the CPA fixing part 3 and the FPC board 4 can be inserted into the main cavity 51 synchronously after being fixed.

[0081] Furthermore, the side end of the gripper 5 is provided with a limiting groove 52 and a mating rib 53 for cooperating with the CPA fixing member 3. The limiting groove 52 is provided at the side end of the gripper 5, and the mating rib 53 is provided at the end of the limiting groove 52 near the CPA fixing member 2, so that when the main plastic shell 1, FPC fixing member 2 and CPA fixing member 3 are inserted into the main cavity 51 at the same time, the CPA fixing member 3 can cooperate with the mating rib 53 and be stably fixed in the limiting groove 52, so as to realize the stable assembly of the CPA fixing member 2 and fix it with the main plastic shell 1, FPC fixing member 2 and gripper 5.

[0082] Combination Figure 17Specifically, when the main plastic shell 1, FPC fastener 2 and CPA fastener 3 are pushed into the main cavity 51 simultaneously, the second elastic wall step 262 on the FPC fastener 2 is abutted by the mating rib 53 under the action of external thrust and its own elastic force, passes through the cavity of the inner wall of the mating rib 53 and enters the limiting groove 52, and springs back and is stuck on the inner side of the mating rib 53, while the first elastic wall step 261 abuts against the outer side of the mating rib 5, thereby fixing the side end of the FPC fastener 2 on the mating rib 53.

[0083] Simultaneously, when the CPA fastener 3 is in the pre-locked state in the first position, the cantilever hook 32 is placed between the first spring wall step 261 and the second spring wall step 262. At this time, the hook end 321 is placed on the inner wall of the mating rib 53 and is abutted by the mating rib 53, so that the mating rib 53 exerts pressure on the hook end 321, moving the hook end 321 toward the FPC fastener 2 and no longer engaging with the first spring wall step 261.

[0084] Combination Figure 18 and Figure 19 Furthermore, the CPA fastener 3 is pushed to move along the side end of the FPC fastener 2 towards the inside of the main cavity 1. Since the FPC fastener 2 is stuck on the mating rib 53, the hook end 321, under the action of external thrust and its own elastic force, passes over the inside of the second spring wall step 262 and moves into the limiting groove 52 to form the second position. The hook end 321 rebounds and locks the second spring wall step 262, thereby limiting the CPA fastener 3 and forming the final locking state of the CPA fastener 2.

[0085] Combination Figure 19 Simultaneously, the CPA fastener 3 moves to the second position, and the spring wall step 26 engages with the cantilever hook 32 to limit the CPA fastener 3. At the same time, the first positioning step 331 and the second positioning step 332 move synchronously along the positioning groove 27 of the FPC fastener 2. Since the first positioning step 331 and the second positioning step 332 are distributed in the first positioning groove 271 and the second positioning groove 272 when the CPA fastener 3 is in the pre-locked state of the first position, and along the moving direction of the CPA fastener 3, the first positioning step 331 and the second positioning step 332 form relative inclined surfaces with the first positioning groove 271 and the second positioning groove 272 respectively, to ensure that the first positioning step 331 and the second positioning step 332 move synchronously along the positioning groove 27 of the FPC fastener 2 to the second position.

[0086] In this way, the first positioning step 331 moves from the second positioning groove 272 to the third positioning groove 273, and the second positioning step 332 moves from the first positioning groove 271 to the second positioning groove 272, so that the third positioning groove 273 and the second positioning groove 272 form a fixed positioning groove, which respectively forms an inclined surface limit with the first positioning step 331 and the second positioning step 332 to limit the CPA fixing member 3. At the same time, it can also be moved back to the first position by the relative inclined surface, which facilitates the disassembly and maintenance of this connector.

[0087] The resulting counter 5 can cooperate with the FPC fastener 2 and the CPA fastener 3 to ensure that both sides of the FPC fastener 2 are fixed, and simultaneously move the CPA fastener 3 from the pre-locked state in the first position to the second position to form the final lock state, thereby improving assembly efficiency and reliability.

[0088] Example 2

[0089] Combination Figures 20 to 22 Based on Embodiment 1, since the FPC fastener 2 is relatively long, in order to ensure reliable cooperation between the FPC fastener 2 and the main plastic part 1, several stepped steps 16 are distributed at intervals in the middle area of ​​the main plastic part 1, and each stepped step 16 has a first step 161 and a second step 162 distributed along the height direction.

[0090] Correspondingly, the central area of ​​the FPC fastener 2 is provided with a step mating groove 28 corresponding to the step 16, so that when the FPC fastener 2 is inserted into the main plastic part 1 from above, at the first height, the step mating groove 28 of the FPC fastener 2 engages in the first step 161, ensuring the reliability of the pre-locked state of the FPC fastener 2. Figure 20 As shown.

[0091] Correspondingly, the FPC fastener 2 continues to move vertically. At the second height, the step mating groove 28 slides down from the first step 161 and engages in the second step 162, ensuring the reliability of the final locked state of the FPC fastener 2. Figure 21 As shown.

[0092] Furthermore, to prevent the opposing component 5 from interfering with the stepped step 16, a clearance groove 54 is provided in the middle region of the opposing component 5 corresponding to the stepped step 16. This ensures that when the FPC fastener 2 and the main plastic shell 1 are simultaneously inserted into the main cavity 51, the stepped step 16 can be simultaneously embedded in the clearance groove 54, thus ensuring assembly reliability. Figure 22 As shown.

[0093] The following example illustrates the working process of this utility model in a specific application. It should be noted that the content described here is only a specific application example of this solution and does not constitute a limitation on this solution.

[0094] The CPA fastener 3 is pushed to move along the side end of the FPC fastener 2 to form a first position. The cantilever hook 32 is engaged in the first spring wall step 261 of the spring wall step 26. The first positioning step 331 and the second positioning step 332 are simultaneously engaged in the first positioning groove 271 and the second positioning groove 272 of the FPC fastener 2 to form a pre-locked state of the CPA fastener 3.

[0095] Furthermore, the FPC fastener 2 and CPA fastener 3 are simultaneously inserted into the main plastic shell 1 from above. The limiting barrier 21 moves vertically along the FPC fastener positioning groove 13, and the opening 22 is horizontally aligned with the groove of the FPC assembly groove 11. The FPC fastener positioning step 23 is simultaneously engaged in the FPC fastener pre-locking step 14 to initially limit the FPC fastener 2 and form the pre-locking state of the FPC fastener 2.

[0096] The FPC board 4 is inserted into the FPC assembly slot 11 through the openings 22 on both sides. The FPC board lock 12 falls into the FPC board pre-positioning slot 41, limiting the FPC board 4 and forming the pre-positioning state of the FPC board 4.

[0097] Furthermore, the limiting barrier 21 is pushed to move vertically along the FPC fastener positioning groove 13, the FPC fastener positioning step 23 disengages from the FPC fastener pre-locking step 14, and moves vertically to the FPC fastener final locking step 15 at the same time, forming a second height. The FPC fastener positioning step 23 is engaged in the FPC fastener final locking step 15, limiting the FPC fastener 2 and forming the final locking state of the FPC fastener 2.

[0098] Simultaneously, the limiting wall 21 moves vertically along the FPC fixing positioning groove 13, and the opening 22 simultaneously abuts against the groove wall of the FPC assembly groove 11. The limiting wall 21 falls into the FPC board fixing position slot 42, and the FPC board 4 cannot be moved backward and fall out of the FPC assembly groove 11, so as to ensure that the FPC board 4 is completely fixed in the FPC assembly groove 11, forming the fixed state of the FPC board 4.

[0099] Further, the main plastic shell 1, FPC fastener 2, CPA fastener 3 and FPC plate 4 are simultaneously pushed into the main cavity 51. The spring wall step 26 of the FPC fastener 2 is fixed on both sides of the mating rib 5. The CPA fastener 3 is pushed, and the cantilever hook 32 passes over the inside of the second spring wall step 262 and moves into the limiting groove 52 to form the second position. The cantilever hook 32 rebounds and locks the second spring wall step 262. Simultaneously, the first positioning step 331 moves from the second positioning groove 272 to the third positioning groove 273 to limit the CPA fastener 3 and form the final locking state of the CPA fastener 2.

[0100] The FPC connector with CPA provided by this utility model, through the cooperation of the main plastic shell 1, FPC fixing part 2, CPA fixing part 3, FPC board 4 and the counter 5, the CPA fixing part 3 moves along the FPC fixing part 2 to form the pre-locked state and the final locked state of the CPA fixing part 2 respectively, and the FPC fixing part 2 moves along the main plastic shell 1 to form the pre-locked state and the final locked state of the FPC fixing part 2 respectively, and simultaneously realizes the insertion and limiting of the FPC board 4. The structure is simple and can effectively improve assembly efficiency and reliability.
