Description

Technical Field

[0001] This utility model relates to a connecting device for soldering bent pin headers on PCB boards, and is applicable to the field of PCB board soldering technology. Background Technology

[0002] A bendable pin header is an L-shaped metal conductor widely used in PCB board connections as a universal connector. It consists primarily of two perpendicular pins. In use, the second pin is inserted vertically into the connector hole on the PCB board, while the first pin remains parallel to the PCB surface. The second pin is then soldered to the PCB board to secure it and establish electrical connection, thus enabling electrical connection between the PCB board and other components. In actual PCB manufacturing, bendable pin headers are typically arranged in rows and neatly soldered onto the PCB board. To ensure neatness, the first pin is pre-inserted into the connector before soldering, with the second pins facing the same direction. The connector is then placed against the PCB board, and the second pins are inserted into their corresponding holes. This connector provides support, ensuring that the soldering height and angle of each pin remain consistent.

[0003] However, some specifications of bent pin headers have a longer second pin length, and the distance between its end and the connector is larger. This causes the connector and the pin header itself to tilt under the gravity of the second pin end when the connector is placed on the PCB board, resulting in skewed pin soldering and affecting the soldering quality of the PCB board. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model proposes a connection device for soldering bent pin headers on PCB boards.

[0005] The technical solution adopted by this utility model is: a connecting device for soldering bent pin headers on a PCB board, including a connecting part for connecting bent pin headers, an auxiliary cover plate detachably connected to the bent pin headers, a plurality of connecting holes through the connecting part for inserting the first pins of the bent pin headers, at least two first support feet abutting the surface of the PCB board on the bottom surface of the connecting part, the auxiliary cover plate including a plate body covering the connecting part and the bottom surface abutting the top surface of the connecting part, at least one second support foot disposed on the bottom surface of the plate body away from the connecting part, and at least one clamping part disposed on the bottom surface of the plate body, the first support feet... The sum of the heights of the connecting parts and the second support foot is the same as the height of the second support foot, and the second support foot is parallel to the second pin of the bent pin header. Each clamping part has at least one pair of fixing posts extending downward from the bottom surface of the board body. The spacing between each pair of fixing posts is less than or equal to the width of the pin of the bent pin header. The auxiliary cover plate has at least two working states. When it is in the first working state, the auxiliary cover plate is disengaged from the bent pin header and from the connecting part and the PCB board. When the auxiliary cover plate is in the second working state, the clamping part clamps the bent pin header between each pair of fixing posts, the board body is placed on the connecting part and abuts against the connecting part, and the second support foot abuts against the PCB board. During soldering, the first pin of the header is pre-inserted into the connecting hole on the connector. Then, the auxiliary cover is placed on the connector, putting the auxiliary cover into its second working state. After both the connector and the auxiliary cover are connected to the header, the entire assembly is placed on the PCB board. The header is clamped by the clamping part, and supported by the first and second support feet against the PCB board, thus forming a stable support structure. This prevents the header from tipping over due to excessively long header pins, ensuring that the header can be kept in a neat state for soldering and guaranteeing the soldering quality of the PCB board. The connection structure between the auxiliary cover, the connector, and the bent header also facilitates the quick removal of the auxiliary cover after soldering, avoiding any impact on subsequent processing of the PCB board.

[0006] Furthermore, the number of first support feet is the same as the number of connecting holes and they correspond one-to-one. Each first support foot is located directly below its corresponding connecting hole. When there are many pins in a row and the connecting part is long, it can prevent the part of the connecting part that is far from the first support foot from deforming and sinking, ensuring the consistency between multiple rows of pins and guaranteeing the welding quality.

[0007] Furthermore, at least two second support legs are provided, and the at least two second support legs are located at the corners of the plate, thereby further improving the stability of the support.

[0008] Furthermore, at least two clamping parts are provided, and the at least two clamping parts are located on the front and rear sides of the connecting part, respectively, to improve the connection stability between the auxiliary cover plate and the bent pin header and to facilitate maintaining the regular posture of the bent pin header.

[0009] Furthermore, each clamping part has at least two pairs of fixing posts, and the at least two pairs of fixing posts are arranged in the left-right direction, which further improves the connection stability between the auxiliary cover plate and the bent pin header.

[0010] Furthermore, each fixed post has a chamfer at its lower end to facilitate the insertion of the pins of the bent-leg pin header between the fixed posts.

[0011] Furthermore, the top surface of the board is set as a plane perpendicular to the second pin of the bent pin header. Setting the top surface of the board as a plane facilitates cooperation with the suction mechanism in automated processing equipment, making it easy for the equipment to automatically pick up materials and place them on the PCB board for soldering, thus achieving automated processing. Setting the plane perpendicular to the second pin ensures that the bent pin header maintains a neat posture when the suction mechanism performs the suction and placement operation.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] The connecting device for soldering bent pin headers on PCB boards in this utility model has a simple structure and is easy to operate. The bent pin header is clamped and fixed by the clamping part on the auxiliary cover plate, and the second support foot cooperates with the first support foot to keep the bent pin header in a neat posture when it is inserted into the PCB board and waiting to be soldered. This avoids tilting or skewing caused by the excessive length of the pin header leads. It not only ensures the soldering quality of the PCB board, but also makes it easy to adapt to automated production equipment without manual assistance or interference, thus improving production efficiency.

[0023] Reference Appendix Figure 1-4 The connection device for soldering bent pin headers on a PCB board in this embodiment includes a connection part 1 for connecting bent pin headers and an auxiliary cover plate 2 that can be detachably connected to the bent pin headers. The connection part 1 has multiple through-holes for supplying first pins of the bent pin headers (as shown in the attached diagram). Figure 1 , 2 The connecting hole 11 (as shown in reference numeral a) is inserted therein. The bottom surface of the connecting part 1 is provided with at least two first support feet 12 that abut against the surface of the PCB board. The auxiliary cover plate 2 includes a plate body 21 that covers the connecting part 1 and whose bottom surface abuts against the top surface of the connecting part 1, at least one second support foot 22 provided on the bottom surface of the plate body 21 away from the connecting part 1, and at least one clamping part 23 provided on the bottom surface of the plate body 21. The sum of the heights of the first support foot 12 and the connecting part 1 is the same as the height of the second support foot 22, and the second support foot 22 is connected to the second pin of the bent pin header (as shown in the attached figure). Figure 1 , 2Parallel to (as shown in reference numeral b), each clamping part 23 has at least one pair of fixing posts 231 extending downward from the bottom surface of the board body 21. The spacing between each pair of fixing posts 231 is less than or equal to the width of the pin of the bent pin header. The auxiliary cover plate 2 has at least two working states. When it is in the first working state, the auxiliary cover plate 2 is disengaged from the bent pin header and from the connecting part 1 and the PCB board. When the auxiliary cover plate 2 is in the second working state, the clamping part 23 clamps the bent pin header between each pair of fixing posts 231, the board body 21 covers the connecting part 1 and abuts against the connecting part 1, and the second support leg 22 abuts against the PCB board. During soldering, the first pin of the bent-pin header is inserted into the connection hole 11 on the connecting part 1 beforehand. Then, the auxiliary cover plate 2 is placed on the connecting part 1, so that the auxiliary cover plate 2 enters the second working state. After the connecting part 1 and the auxiliary cover plate 2 are connected to the header, the whole assembly is placed on the PCB board. On the one hand, the header is clamped by the clamping part 23, and on the other hand, the first support foot 12 and the second support foot 22 abut against the PCB board to form a support, thus forming a stable support structure to prevent tipping caused by the excessive length of the header pin, ensuring that the header can be kept in a regular state to complete the soldering and ensuring the soldering quality of the PCB board. The connection structure between the auxiliary cover plate 2 and the connecting part 1 and the bent-pin header also makes it easy to quickly remove the auxiliary cover plate 2 after soldering, avoiding affecting the subsequent processing of the PCB board.

[0024] In a more preferred embodiment, the number of first support feet 12 is the same as the number of connecting holes 11 and they correspond one-to-one.

[0028] In a more preferred embodiment, each fixing post 231 has a chamfer at its lower end to facilitate the insertion of the pins of the bent pin header into the fixing posts.

[0029] In a more preferred embodiment, the top surface of the board body 21 is set as a plane perpendicular to the second pin of the bent pin header. Setting the top surface of the board body as a plane facilitates cooperation with the suction mechanism in the automated processing equipment, making it convenient for the equipment to automatically pick up materials and place them on the PCB board for soldering, thereby realizing automated processing. Setting the plane perpendicular to the second pin ensures that the bent pin header is always kept in a regular posture when the suction mechanism performs the suction and placement operation.
