Description

Technical Field

[0001] The utility model relates to the technical field of circuit board pin headers, and more specifically, to a pin header assembly for connecting wires on a PCB circuit board. Background Art

[0002] A pin header assembly for connecting wires to a PCB circuit board is an electronic component designed to achieve reliable electrical connections between circuit boards or between a circuit board and other electronic components. It mainly transmits signals or power through pin headers (a series of side-by-side metal pins). This assembly is widely used in many fields such as electronic manufacturing, prototype design and testing due to its high versatility and flexibility.

[0003] However, some existing pin header assemblies for connecting wires to PCB circuit boards still have many deficiencies. First, some devices cannot ensure the precise connection between the wire row and the circuit board, which may lead to unstable connection, increase the risk of errors, and reduce the accuracy and reliability of assembly. Secondly, some devices cannot effectively fix the wire ends, making the wire ends easy to loosen during use, affecting the stability of the electrical connection, which may cause circuit failure or unstable performance. Finally, the locking process of some devices relies entirely on manual operation, which not only increases the labor intensity of the operator, but also may lead to inconsistency in locking force and effect, affecting the reliability and performance of the entire assembly.

[0030] In this embodiment, when the needle and thread clamping mechanism needs to be operated, the thread row 2 is connected to the collecting plate 5, the upper clamping plate 3 is installed on the upper end surface of the collecting plate 5, and the lower clamping plate 4 is installed on the bottom end surface of the collecting plate 5. When the wire in the collecting plate 5 is placed, the upper clamping plate 3 and the lower clamping plate 4 work together to firmly clamp the wire and ensure the stability of the position of the wire during operation.

[0031] More specifically, the thread end is introduced into the clamping sleeve 6, and several groups of slope blocks 7 are installed on the inner wall of the clamping sleeve 6. Each group of slope blocks 7 is equipped with a push block 8. One end of the threaded tube 9 is sleeved in the clamping sleeve 6 and is threadedly connected to one end of the clamping sleeve 6. When the push plate 10 moves under the action of the threaded tube 9, it pushes the push block 8 to slide along the slope block 7. This sliding action causes the push block 8 to clamp the thread end, thereby completing the locking process of the thread end.

[0032] See also Figure 1-5, as an implementation method of the auxiliary thread locking mechanism: the locking auxiliary mechanism includes a driving motor 11, a rotating shaft 12, a main gear 13, an internal gear 14 and a turntable 15, the driving motor 11 is installed on the back end surface of the circuit board body 1, the rotating shaft 12 is connected to the output end of the driving motor 11, the main gear 13 is installed at one end of the rotating shaft 12, the main gear 13 and the internal gear 14 are meshed and connected, the internal gear 14 is fixedly installed on the turntable 15, and the turntable 15 fixing sleeve 19 is installed on the threaded tube 9.

The internal gear 14 is fixedly mounted on the rotating disk 15, and the rotating disk 15 fixing sleeve 19 is mounted on the threaded tube 9. When the driving motor 11 is started, the rotating disk 15 and the threaded tube 9 are driven to rotate through the meshing of the main gear 13 and the internal gear 14. The rotation of the rotating disk 15 drives the threaded tube 9 to rotate, so that the push plate 10 moves along the threaded tube 9, which assists in completing the locking process of the thread head.

[0034] Please refer to Figure 1-5 As a further implementation of the needle and thread clamping mechanism, the thread end locking mechanism and the locking auxiliary mechanism: a round wire 16 is provided at one end of the thread row 2, and the round wire 16 extends into and passes through the circuit board body 1, and the other end of the round wire 16 is locked and fixed by the thread end locking mechanism, a limiting plate 17 is provided on the inner side wall of the clamping sleeve 6, and a spring 18 is provided on the push plate 10, and the other end of the spring 18 is connected to the limiting plate 17, a fixing sleeve 19 is provided on the back of the circuit board body 1, and the turntable 1 The bottom of 5 is in contact with the fixing sleeve 19, a limit block 20 is provided at the bottom of the pushing block 8, a limit groove 21 is provided on the slope block 7, and the limit block 20 can be embedded in the limit groove 21 to cooperate with the limit sliding, side rods 22 are provided on the sides of the fixing sleeve 19 and the clamping sleeve 6, and connecting rods 23 are provided between the side rods 22, a support plate 24 is provided on the side of the fixing sleeve 19, and a support rod 25 is provided at the bottom of the support plate 24, and the other end of the support rod 25 is connected to the back of the circuit board body 1.

[0035] Specifically, by setting the limit plate 17 on the inner wall of the clamping sleeve 6 and installing the spring 18 on the push plate 10, and the use of the limit block 20 and the limit groove 21, the stability and reliability of the mechanism are increased. These design details make the locking mechanism more stable during operation and reduce misoperation caused by vibration or unexpected thrust. The design of the fixing sleeve 19, the side rod 22 and the support plate 24 not only provides additional structural stability, but also makes the entire assembly easier to install on the circuit board. In particular, the connection design between the fixing sleeve 19 and the back of the circuit board body 1 provides convenience for the fixing and maintenance of the device. The setting of the side rod 22 and the connecting rod 23 enhances the mechanical structure of the entire device, ensuring stability and durability under various operating conditions. The design of the support plate 24 and the support rod 25 further ensures the structural integrity and stable support of the circuit board during use.

One end of the threaded tube 9 is sleeved in the clamping sleeve 6 and is threadedly connected to one end of the clamping sleeve 6. When the push plate 10 moves under the action of the threaded tube 9, it pushes the pushing block 8 to slide along the slope block 7. This sliding action enables the pushing block 8 to clamp the thread end, thereby completing the locking process of the thread end.

[0038] When the locking auxiliary mechanism is required to be operated, the driving motor 11 is installed on the back end surface of the circuit board body 1, and the output end of the motor is connected to the rotating shaft 12. The main gear 13 is installed on the rotating shaft 12, and the main gear 13 is meshed and connected with the internal gear 14. The internal gear 14 is fixedly installed on the rotating disk 15, and the rotating disk 15 fixing sleeve 19 is installed on the threaded tube 9. When the driving motor 11 is started, the rotating disk 15 and the threaded tube 9 are driven to rotate through the meshing of the main gear 13 and the internal gear 14. The rotation of the rotating disk 15 drives the threaded tube 9 to rotate, so that the push plate 10 moves along the threaded tube 9 to assist in completing the locking process of the thread head.
