[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0024] Reference Figures 1-6 As shown: A nested positioning structure for terminal crimping includes a nested positioning carrier 1 and a flexible circuit board 2. The nested positioning carrier 1 has a first placement groove 11 and a second placement groove 12. The flexible circuit board 2 is divided into a bent portion 22 and a vertical portion 21, with the vertical portion 21 placed in the second placement groove 12. A lower insert 3 and an upper insert 4 are disposed in the first placement groove 11, with the lower insert 3 abutting against the first placement groove 11 and the upper insert 4 engaging with the lower insert 3. The bent portion 22 of the flexible circuit board 2 is located between the lower insert 3 and the upper insert 4.
[0025] Due to limitations in product shape, some products require bending before terminal crimping in existing technologies, and there is a lack of devices that can position both the bent and vertical ends. To address this issue, the vertical portion 21 of the flexible circuit board 2 is first placed in the second placement slot 12 of the nested positioning carrier 1 to achieve vertical positioning. The bent portion 22 of the flexible circuit board 2 is placed between the lower insert 3 and the upper insert 4. The lower insert 3 is pressed against the first placement slot 11 to ensure its stable position, and the upper insert 4 engages with the lower insert 3. This tight cooperation securely fixes the bent portion 22, ensuring accurate positioning of both the bent portion 22 and the vertical portion 21 during terminal crimping. This solves the problem of the lack of a positioning device for both the bent and vertical ends in existing technologies, allowing for smooth and precise terminal crimping even after bending.
[0026] Reference Figure 4 As shown: A first limiting rod 111 is provided in the first placement groove 11; a first limiting groove 31 is provided on the lower insert 3; the first limiting rod 111 is inserted into the first limiting groove 31.
[0027] When the lower insert 3 is placed in the first placement groove 11, the first limiting groove 31 on the lower insert 3 corresponds to the first limiting rod 111 in the first placement groove 11. The first limiting rod 111 is inserted into the first limiting groove 31, which restricts the displacement of the lower insert 3 from the side, further ensuring the stability of the lower insert 3 in the tight state with the first placement groove 11, preventing the lower insert 3 from shifting or shaking during the crimping operation, and making it fit more tightly with the upper insert 4, thereby providing more reliable positioning for the bending part 22 of the circuit board 2, and ensuring that the entire terminal crimping operation is carried out accurately and stably.
[0028] Reference Figure 3 and Figure 4 As shown: The lower insert 3 is provided with a second limiting rod 32; the upper insert 4 is provided with a second limiting groove 41; the second limiting rod 32 is inserted into the second limiting groove 41.
[0029] When the upper insert 4 and the lower insert 3 are engaged to fix the bent portion 22 of the flexible circuit board 2, the second limiting rod 32 of the lower insert 3 is inserted into the second limiting groove 41 of the upper insert 4, which restricts the relative movement of the upper insert 4 and the lower insert 3, making the connection between the two more stable. This effectively avoids misalignment of the upper insert 4 and the lower insert 3 due to external forces or other factors during the crimping process, thereby reliably clamping the bent portion 22 of the flexible circuit board 2 and ensuring that the terminal crimping work is carried out smoothly and accurately.
[0030] Reference Figure 2 and Figure 4 As shown: The side wall of the second placement groove 12 is provided with a positioning groove 121; the vertical part 21 of the circuit board 2 is provided with a positioning block 211; the positioning block 211 is disposed in the positioning groove 121.
[0031] The vertical part 21 of the flexible circuit board 2 is placed in the second placement groove 12. The positioning block 211 of the vertical part 21 of the flexible circuit board 2 cooperates with the positioning groove 121 on the side wall of the second placement groove 12. The positioning block 211 is set in the positioning groove 121, which restricts the displacement of the vertical part 21 of the flexible circuit board 2, making its position in the second placement groove 12 more accurate and stable. This avoids the vertical part 21 from shaking or shifting during the terminal crimping process, ensuring that the entire nested positioning structure can complete the terminal crimping task efficiently and accurately.
[0032] Reference Figures 4-6 As shown: The flexible circuit board 2 has a positioning hole 221 on the bent part 22; the lower insert 3 is provided with a positioning rod 33; when the lower insert 3 and the upper insert 4 are engaged and connected, the positioning rod 33 is inserted into the positioning hole 221.
[0033] When the bent portion 22 of the flexible circuit board 2 is placed between the lower insert 3 and the upper insert 4, the positioning rod 33 on the lower insert 3 aligns with the positioning hole 221 of the bent portion 22 of the flexible circuit board 2. As the lower insert 3 and the upper insert 4 engage, the positioning rod 33 is inserted into the positioning hole 221 to restrict the movement of the bent portion 22 of the flexible circuit board 2, thus fixing it firmly and preventing positional deviation of the bent portion 22 during terminal crimping. This ensures that the entire nested positioning structure can complete the terminal crimping operation with extremely high precision, guaranteeing product quality.
[0034] Reference Figures 3-5 As shown: The nested positioning carrier 1 is provided with an anti-detachment component 5; the anti-detachment component 5 includes an anti-detachment groove 51 and a small iron piece 52; the anti-detachment groove 51 is opened in the nested positioning carrier 1 and is located on the side of the first placement groove 11; the small iron piece 52 is disposed in the anti-detachment groove 51 and abuts against the side wall of the lower insert 3.
[0035] When the lower insert 3 is placed in the first placement slot 11, the small iron piece 52 abuts against the side wall of the lower insert 3, applying a stable force from the side. This effectively limits the possible displacement of the lower insert 3 in the horizontal direction, preventing it from coming out due to vibration, external impact, or other factors during the terminal crimping process. This allows the entire nested positioning structure for terminal crimping to operate continuously and accurately, ensuring the smooth completion of the terminal crimping operation and meeting product quality standards.
[0036] Reference Figures 1-6 As shown: The small iron sheet 52 is available in various specifications to accommodate different product models.
[0037] When preparing for terminal crimping for a specific product model, select a small iron piece 52 of appropriate specification according to the actual product situation and place it into the anti-detachment groove 51. After installing the lower insert 3, the small iron piece 52 of this specification can be pressed against the side wall of the lower insert 3 just right to stabilize the lower insert 3 and avoid the problem of being too loose or too tight due to different product models.
[0038] Reference Figures 1-6 As shown: The anti-detachment groove 51 and the small iron piece 52 are provided with a fixing slot 53, and a fixing rod is inserted into the fixing slot 53 to tightly connect the anti-detachment groove 51 and the small iron piece 52.
[0039] Insert the fixing rod into the fixing slot 53, so that the small iron piece 52 is tightly connected to the anti-dislodgement groove 51. In this way, during the subsequent terminal crimping process, even if subjected to equipment vibration or accidental impact from external forces, the small iron piece 52 will not easily shift or dislodge within the anti-dislodgement groove 51, and will always remain in a stable state against the side wall of the lower insert 3, reliably limiting the horizontal displacement of the lower insert 3.
[0040] In the terminal crimping process, when bending is required due to product shape limitations, this nested positioning structure is used. First, the vertical part 21 of the flexible circuit board 2 is precisely placed into the second placement groove 12 of the nested positioning carrier 1. The side wall positioning groove 121 cooperates with the positioning block 211 of the vertical part 21 of the flexible circuit board 2, restricting the displacement of the vertical part 21 and achieving precise vertical positioning. For the bent part 22, it is placed between the lower insert 3 and the upper insert 4. The lower insert 3 abuts against the first placement groove 11, and the first limiting rod 111 in the first placement groove 11 is inserted into the first limiting groove 31 of the lower insert 3, stabilizing the lower insert 3 from the side. The second limiting rod 32 of the lower insert 3 is inserted into the second limiting groove 41 of the upper insert 4, stabilizing the connection between the two and reliably clamping the bent part 22. At the same time, the positioning rod 33 of the lower insert 3 is inserted into the positioning hole 221 of the bent part 22 of the flexible circuit board 2, further fixing the bent part 22. The nested positioning carrier 1 has an anti-dislodgement groove 51 and a small iron piece 52 that is adapted to different products. During installation, the small iron piece 52 abuts against the side wall of the lower insert 3. The fixing rod between the anti-dislodgement groove 51 and the small iron piece 52 is inserted into the fixing slot 53, so that the small iron piece 52 and the anti-dislodgement groove 51 are integrated. Even if there is vibration or external impact, the small iron piece 52 will remain stable in the anti-dislodgement groove 51, continuously restricting the displacement of the lower insert 3 from the side, ensuring the stability of the entire positioning structure, so that the product can be bent smoothly and with high precision to complete the terminal crimping, ensuring that the product quality meets the standards.
[0041] The lower insert 3 and the lower insert 4 can simultaneously solve the problem of precise setting in the dispensing process. The dispensing carrier is equipped with an insert base plate, which can be used to position the lower insert 31. After the insert is placed on the insert base plate, the dispensing cover is then placed on top, and the dispensing process begins.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
