Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a bendable connector with anti-floating height. Background Technology

[0002] Right-angle connectors are widely used for connecting PCBs (printed circuit boards) to external electrical components. However, during the actual soldering process, due to the surface tension of the solder, the soldering leads of the connector are subjected to a downward force, causing the connector to rotate relative to the PCB and lift up at the soldering end away from the conductive terminal, resulting in a floating phenomenon. This not only affects the stability of the connection but may also lead to a decrease in soldering quality, affecting the performance of the entire circuit.

[0003] The shortcomings of existing technology: 1. The floating height problem has not been fully resolved: During the welding process of existing bend connectors, the surface tension of the solder causes the connector to rotate unstablely, resulting in floating height, which affects the welding quality and electrical performance of the product.

[0004] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a bendable connector with anti-floating height.

[0006] To achieve the above objectives, the specific solution of this utility model is as follows: This utility model provides a bendable connector with anti-floating height, comprising: Insulating body; Several conductive terminals are led out horizontally through the insulating body and bent downwards to make an electrical connection with the PCB in a bent form. Soldering foot, the connection point between the end of the conductive terminal and the PCB, used for soldering and fixing the conductive terminal to the PCB; The support component is located at the end where the conductive terminal is soldered to the PCB, and is situated between the insulating body and the PCB. The support component has a support surface that can abut against the PCB during the welding process; The surface tension of the solder exerts a downward force on the soldering leads, causing the connector to rotate relative to the PCB, thereby causing the soldering end away from the conductive terminal to lift up and form a floating height. The support is used to prevent the insulation body from lifting up due to the welding feet being pulled down, thus creating a floating effect.

[0007] Furthermore, the support member is provided with a plurality of first insertion holes that mate with conductive terminals; Both ends of the first insertion hole along the insertion direction are chamfered so that the support can be inserted in both directions.

[0008] Furthermore, the plurality of conductive terminals include: a first terminal group and a second terminal group; The first terminal group and the second terminal group are arranged parallel to each other; The first terminal group includes a plurality of first conductive terminals arranged at equal intervals; The second terminal group includes a plurality of second conductive terminals arranged at equal intervals.

[0009] Furthermore, the conductive terminal is a bent-ended terminal, which is bent relative to the PCB surface and electrically connected to the PCB through hole or pad. The support surface of the support member is located outside the soldering area of ​​the conductive terminal to avoid hindering solder wetting and tin climbing.

[0010] Furthermore, the conductive terminal is L-shaped, with one end being a conductive end and the other end being a soldering end. The soldering end is provided with soldering feet for soldering the conductive terminal onto the PCB, and the conductive end is a contact end for electrical connection with external connectors.

[0011] Furthermore, the support member is fixed to the welding end of the conductive terminal by means of snap-fit, interference fit, or hot riveting.

[0012] Furthermore, the insulating body has a chamfer on one side of the welding end to adapt to the fixture and assembly direction, thereby improving assembly efficiency.

[0013] Furthermore, the support member has a lateral dimension that is not less than the preset minimum support width, so as to maintain stable support under welding heat and external force disturbance, and avoid warping or floating again due to local pressure.

[0014] Furthermore, a pressure block is also fitted onto the top of the insulating body.

[0015] The technical solution of this utility model has the following beneficial effects: 1. Preventing floating phenomenon: By adding a support component to the connector, the solder feet can be effectively prevented from pulling up due to the surface tension of the solder during the soldering process, thus preventing the connector from tilting away from the conductive terminals at the soldering end, thereby eliminating the floating phenomenon and ensuring a stable connection between the connector and the PCB.

[0016] 2. Improved welding quality: The design of the support effectively supports the welding feet, ensuring stability during the welding process, which helps to improve welding quality and ensure the reliability and longevity of electrical connections.

[0017] 3. Optimized support structure: The socket design and chamfering of the support enable bidirectional insertion, improving the ease of assembly. At the same time, the support is strengthened by locking, interference fit or hot riveting, avoiding instability problems that may occur during the soldering process of the connector.

[0023] Combination Figures 2-8 As shown, this utility model provides a bendable connector with anti-floating height, comprising: Insulating body 1; Several conductive terminals are led out horizontally through the insulating body 1 and bent downwards to be electrically connected to the PCB8 in a bent form. Soldering foot 2, the connection point between the end of the conductive terminal and PCB8, is used for soldering and fixing the conductive terminal to PCB8; Support 3 is disposed at the end where the conductive terminal is soldered to PCB8, and is located between the insulating body 1 and PCB8; The support member 3 has a support surface that can abut against the PCB8 during the welding process; The surface tension of the solder exerts a downward force on the soldering pin 2, causing the connector to rotate relative to the PCB8, thereby causing the soldering end away from the conductive terminal to lift up and form a floating height. The support 3 is used to prevent the welding foot 2 from pulling down and causing the insulating body 1 to lift up, thus creating a floating effect.

[0024] The support member 3 is provided with several first insertion holes that are connected to the conductive terminals. Both ends of the first insertion hole along the insertion direction are provided with chamfers 4 so that the support member 3 can be inserted in both directions.

[0025] The plurality of conductive terminals include: a first terminal group 5 and a second terminal group 6; The first terminal group 5 and the second terminal group 6 are arranged parallel to each other; The first terminal group 5 includes a plurality of first conductive terminals arranged at equal intervals; The second terminal group 6 includes a plurality of second conductive terminals arranged at equal intervals.

[0026] The conductive terminal is a bent-in terminal, which is bent relative to the PCB8 surface and electrically connected to the PCB8 through hole or solder pad. The support surface of the support member 3 is located outside the soldering area of ​​the conductive terminal to avoid hindering solder wetting and tin climbing.

[0027] The conductive terminal is L-shaped, with one end being a conductive end and the other end being a soldering end. The soldering foot 2 on the soldering end is used to solder the conductive terminal onto the PCB8. The conductive end is a contact end used for electrical connection with external connectors.

[0028] The support member 3 is fixed to the welding end of the conductive terminal by means of snap-fit, interference fit or hot riveting.

[0029] The insulating body 1 has a chamfer 4 on one side of the welding end to adapt to the fixture and assembly direction and improve assembly efficiency.

[0030] The support member 3 has a lateral dimension that is not less than the preset minimum support width, so as to maintain stable support under welding heat and external force disturbance, and avoid warping or floating again due to local pressure.

[0031] A pressure block 7 is also clamped on the top of the insulating body 1.

[0032] The principle of this utility model is as follows: This utility model of an anti-floating bend-fit connector solves the problem of connector floating caused by solder surface tension during welding by adding a support member 3 to the traditional bend-fit connector design. Its working principle is as follows: 1. Bending Design of Conductive Terminals: This connector uses bent conductive terminals. These terminals pass horizontally through the insulating body 1 and bend downwards to form an L-shaped structure. The soldered ends are electrically connected to the PCB8 pads or through-holes. This design allows the connector to be securely electrically connected to the PCB8, ensuring the stability of electrical transmission.

[0033] 2. Fixing function of soldering pin 2: Soldering pin 2 is provided at the end of the conductive terminal. This soldering pin 2 is used to fix the conductive terminal to the PCB8. During the soldering process, the surface tension of the solder exerts a downward force on the soldering pin 2, which causes the connector to rotate relative to the PCB8 and may lift up on the side of the soldering end away from the conductive terminal, forming a floating position.

[0034] 3. Anti-floating function of support member 3: To prevent the aforementioned floating phenomenon, support member 3 is provided in the connector. Support member 3 is located at the end where the conductive terminal is soldered to PCB8, and is located between the insulating body 1 and PCB8. Support member 3 has a support surface that can contact PCB8, effectively preventing the soldering pin 2 from being pulled down during soldering, and avoiding the insulating body 1 from tilting up due to being pulled down, thereby preventing the floating phenomenon from occurring.

[0035] 4. Structure and Fit of Support Component 3: Support component 3 has multiple insertion holes for mating with conductive terminals, and both ends of the insertion holes are chamfered (4), allowing support component 3 to be inserted in both directions, thus improving assembly convenience. Support component 3 is fixed to the welding end of the conductive terminal by snap-fit, interference fit, or hot riveting, ensuring its stability during the welding process.

[0036] 5. Dimensions and stability of support component 3: The lateral dimension of support component 3 is not less than the preset minimum support width. This ensures that support component 3 can maintain sufficient stable support during the welding process, avoiding floating or lifting caused by local pressure. At the same time, the support surface of support component 3 is located outside the welding area of ​​the conductive terminal, avoiding interference with solder wetting and solder creep.

[0037] 6. Improved assembly efficiency: The insulating body 1 of the connector has a chamfer 4 on one side of the welding end to adapt to the fixture and assembly direction, thereby improving assembly efficiency and reducing the difficulty and time of operation in the production process.

[0038] Through the above design, the anti-floating bend connector can effectively solve the floating problem caused by the surface tension of the solder during the welding process, ensuring the stability and reliability of the connector and improving the welding quality.
