[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] Embodiment 1:

[0028] Figure 1 It shows a schematic structural diagram of the bent pin header in the embodiment of the present utility model, Figure 2 It shows the front view of the structure of the bent pin header in the embodiment of the present utility model; Figure 3 It shows the side view of the structure of the bent pin header in Embodiment 1 of the present utility model. The bent pin header includes a plurality of pin header bodies 1 arranged side by side. The pin header body 1 is provided with a bending position 13, and the bending position 13 is provided with more than two bending parts. Based on the plurality of pin header bodies 1 arranged side by side, the pins of the plurality of pin header bodies 1 can be neatly arranged. Combining with the queue distribution structure of the electrode pads of the plurality of main PCB boards on the LED lamp board, the convenience of the insertion connection between the bent pin header and the LED lamp board can be improved.

[0029] Further, a plurality of the bending parts are formed on the pin header body 1 based on the bending position 13 to reduce the structural rigidity of the pin header body 1 and improve the structural elasticity of the pin header body 1, so as to improve the reliability when the pin header body 1 realizes the electrical connection between the LED lamp board and the main PCB board.

[0030] The pin header body 1 is provided with an LED lamp board connection end 11 and a main PCB board connection end 12. Both the LED lamp board connection end 11 and the main PCB board connection end 12 are provided with rubber sleeves 2. Any two adjacent pin header bodies 1 are connected based on the rubber sleeve 2. The plurality of pin header bodies 1 in the bent pin header are connected based on the rubber sleeve 2 to ensure that a preset interval is maintained between the respective pin header bodies 1 and improve the stability of the structural connection of the pin header bodies 1 in the bent pin header.

[0031] Furthermore, by providing the rubber sleeve 2 at the LED lamp board connection end 11 and the main PCB board connection end 12 of the pin header body 1, the connection stability between several pin header bodies 1 within the bent pin header is improved, and the risk of damage to the pin header body 1 during the insertion connection between the LED lamp board and the main PCB board is reduced.

[0032] Specifically, the pin header body 1 forms a first segment and a second segment based on the bending position 13. The length of the first segment is a, and the length of the second segment is b. The constraint relationship between a and b is: a < b. The LED lamp board connection end 11 is provided on the first segment, and the main PCB board connection end 12 is provided on the second segment. The length a of the first segment is approximately 1 / 4 of the total length of the pin header body 1, and sufficient length is reserved on the second segment to meet the insertion installation requirements of the main PCB board.

[0033] Specifically, a straight segment can be formed between two adjacent bending portions within the bending position 13. By performing synchronous bending operations on several pin header bodies 1 through a bending device, one bending portion is formed corresponding to each bending operation, and a straight segment is formed between two adjacent bending portions, thereby improving the convenience of the bending operation by the bending device.

[0034] An arc segment is also formed between two adjacent bending portions within the bending position 13. By adjusting the bending angle parameter of the bending device, an arc segment is formed between two adjacent bending portions, which can further improve the structural elasticity of the pin header body 1, enabling the pin header body 1 to bear the extrusion force between the LED lamp board and the main PCB board.

[0035] Specifically, a groove is provided at the connection position of the rubber sleeve 2 of any two adjacent pin header bodies 1. Based on the groove, the convenience of separating two adjacent pin header bodies 1 of the bent pin header is improved, so as to adjust the number of pin header bodies 1 of the bent pin header according to the electrical connection requirements between the LED lamp board and the main PCB board, thereby meeting the electrical connection requirements between the LED lamp board and the main PCB board.

[0036] Specifically, the rubber sleeve 2 is sleeved on the pin header body 1. One end of the pin header body 1 extending outside the rubber sleeve 2 has a length of h1, and the value range of h1 is: 2 mm ≤ h1 ≤ 6 mm. Preferably, the distance between the LED lamp board connection end 11 of the pin header body 1 and the adjacent rubber sleeve 2 is between 2 mm and 3 mm, so that the pin header body 1 can be inserted into the pad position of the LED lamp board to meet the electrical connection requirements between the pin header body 1 and the LED lamp board. The distance between the main PCB board connection end 12 of the pin header body 1 and the adjacent rubber sleeve 2 is between 3 mm and 6 mm, so that the main PCB connection end 12 of the pin header body 1 has enough distance to meet the electrical connection requirements between the bent pin header and the main PCB board.

[0037] Specifically, a heat dissipation gap is provided between the main PCB board connection end 12 of the pin header body 1 and the adjacent rubber sleeve 2. That is, after the main PCB board connection end 12 of the pin header body 1 is electrically connected to the circuit board structure of the main PCB board, a heat dissipation gap is formed between the rubber sleeve 2 at the main PCB board connection end 12 of the pin header body 1 and the circuit board structure of the main PCB board, avoiding contact between the rubber sleeve 2 and the circuit board of the main PCB board, thereby ensuring the heat dissipation effect between the rubber sleeve 2 of the pin header body 1 and the main PCB board.

[0038] Specifically, an exhaust groove 21 is provided on the rubber sleeve 2 at the LED lamp board connection end 11. The opening direction of the exhaust groove 21 faces the LED lamp board connection end 11. When the pin header body 1 is electrically connected to the LED lamp board based on the LED lamp board connection end 11, the rubber sleeve 2 at the LED lamp board connection end 11 is in contact with the LED lamp board, which can limit and support the pin header body 1 and improve the connection reliability between the pin header body 1 and the LED lamp board.

[0039] Furthermore, the groove depth of the exhaust groove 21 is h2, and the value range of h2 is: 0.2 mm ≤ h2 ≤ 1 mm. When the LED lamp board connection end 11 of the pin header body 1 is welded to the pad on the LED lamp board by wave soldering, the welding holes corresponding to the LED lamp board connection end 11 on the LED lamp board are prone to thermal expansion, resulting in the rise of gas. Based on the exhaust groove 21, the rising gas at the connection position between the pin header body 1 and the LED lamp board can be guided, avoiding the situation of pin ejection and high void ratio in the welding holes, thereby improving the connection stability and electrical performance between the pin header body 1 and the LED lamp board.

[0040] Specifically, please refer to Figure 3, in this embodiment, the bending position 13 includes a first bending portion 131 and a second bending portion 132. The bending angle of the first bending portion 131 is α, and the bending angle of the second bending portion 132 is β. The constraint relationship between α and β is: α + β = 180°. The bending directions of the first bending portion 131 and the second bending portion 132 are opposite. The LED lamp board connection end 11 and the main PCB board connection end 12 of the pin header body 1 are misaligned based on the bending position 13, so that the main PCB board connection end 12 of the bent pin header can meet the electrical connection requirements of the main PCB board. At the same time, the LED lamp board connection end 11 of the bent pin header can be staggered from the positions of the electronic components on the LED lamp board, reducing the impact on the performance of the electronic components on the LED lamp board during the soldering of the bent pin header.

[0041] Further, based on the bending position 13, the insertion position of the bent pin header is adjusted so that the LED lamp board connection end 11 and the main PCB board connection end 12 of the bent pin header can be misaligned to meet the electrical connection requirements of the LED lamp board and the main PCB board.

[0042] The embodiment of the present utility model provides a bent pin header. Based on the first bending portion 131 and the second bending portion 132 of the bending position 13, the structural rigidity of the bent pin header is reduced, and the stability of the electrical connection between the bent pin header and the LED lamp board and the main PCB board is improved. Based on the bending position 13, the LED lamp board connection end 11 and the main PCB board connection end 12 are misaligned, which can meet the electrical connection between different LED lamp boards and the main PCB board.

[0043] Embodiment Two:

[0044] Figure 4 shows a schematic structural diagram of the bent pin header in the embodiment of the present utility model, Figure 5 shows the main view of the structure of the bent pin header in the embodiment of the present utility model; Figure 6 shows the side view of the structure of the bent pin header in Embodiment One of the present utility model. The bent pin header includes a plurality of pin header bodies 1 arranged side by side. The pin header body 1 is provided with a bending position 13. The bending position 13 is provided with more than two bending portions. Based on the plurality of pin header bodies 1 arranged side by side, the pins of the plurality of pin header bodies 1 can be neatly arranged. Combining with the queue distribution structure of the electrode pads of a plurality of electronic components on the LED lamp board, the convenience of the insertion connection between the bent pin header and the LED lamp board can be improved.

[0045] Further, based on the bending position 13, a plurality of the bending portions are formed on the pin header body 1 to reduce the structural rigidity of the pin header body 1, improve the structural elasticity of the pin header body 1, and improve the reliability when the pin header body 1 realizes the electrical connection between the LED lamp board and the main PCB board.

[0046] The pin header body 1 is provided with an LED lamp board connection end 11 and a main PCB board connection end 12. Rubber sleeves 2 are provided at both the LED lamp board connection end 11 and the main PCB board connection end 12. Any two adjacent pin header bodies 1 are connected based on the rubber sleeves 2, and several pin header bodies 1 within the bent pin header are connected based on the rubber sleeves 2, ensuring a preset interval is maintained between each pin header body 1 and improving the structural connection stability of the pin header bodies 1 within the bent pin header.

[0047] Furthermore, by providing the rubber sleeves 2 at the LED lamp board connection end 11 and the main PCB board connection end 12 of the pin header body 1, the connection stability between several pin header bodies 1 within the bent pin header is improved, and the risk of damage to the pin header body 1 when the bent pin header is inserted and connected between the LED lamp board and the main PCB board is reduced.

[0048] Specifically, the pin header body 1 forms a first section and a second section based on the bent position 13. The length of the first section is a, and the length of the second section is b. The constraint relationship between a and b is: a < b. The LED lamp board connection end 11 is provided on the first section, and the main PCB board connection end 12 is provided on the second section. The length a of the first section is approximately 1 / 4 of the total length of the pin header body 1, and sufficient length is reserved on the second section to meet the insertion installation requirements of the main PCB board.

[0049] Specifically, a straight section can be formed between two adjacent bent portions within the bent position 13. By performing synchronous bending operations on several pin header bodies 1 through a bending device, one bent portion is formed corresponding to each bending operation, and a straight section is formed between two adjacent bent portions, improving the convenience of the bending operation by the bending device.

[0050] An arc section is also formed between two adjacent bent portions within the bent position 13. By adjusting the bending angle parameter of the bending device, an arc section is formed between two adjacent bent portions, which can further improve the structural elasticity of the pin header body 1, enabling the pin header body 1 to bear the extrusion force between the LED lamp board and the main PCB board.

[0051] Specifically, a groove is provided at the connection position of the rubber sleeves 2 of any two adjacent pin header bodies 1. Based on the groove, the convenience of separating two adjacent pin header bodies 1 of the bent pin header is improved, so as to adjust the number of pin header bodies 1 of the bent pin header according to the electrical connection requirements of the LED lamp board, thereby meeting the electrical connection requirements between the LED lamp board and the main PCB board.

[0052] Specifically, the rubber sleeve 2 is sleeved on the pin header body 1. One end of the pin header body 1 extending outside the rubber sleeve 2 has a length of h1, and the value range of h1 is: 2 mm ≤ h1 ≤ 6 mm. Preferably, the distance between the LED lamp board connection end 11 of the pin header body 1 and the adjacent rubber sleeve 2 is between 2 mm and 3 mm, so that the pin header body 1 can be inserted into the pad position of the LED lamp board to meet the electrical connection requirements between the pin header body 1 and the LED lamp board. The distance between the main PCB board connection end 12 of the pin header body 1 and the adjacent rubber sleeve 2 is between 3 mm and 6 mm, so that the main PCB board connection end 12 of the pin header body 1 has enough distance to meet the electrical connection requirements between the bent pin header and the main PCB board.

[0053] Specifically, a heat dissipation gap is provided between the main PCB board connection end 12 of the pin header body 1 and the adjacent rubber sleeve 2, that is, after the main PCB board connection end 12 of the pin header body 1 is electrically connected to the circuit board structure of the main PCB board, a heat dissipation gap is formed between the rubber sleeve 2 at the main PCB board connection end 12 of the pin header body 1 and the circuit board structure of the main PCB board, avoiding contact between the rubber sleeve 2 and the circuit board of the main PCB board, thereby ensuring the heat dissipation effect between the rubber sleeve 2 of the pin header body 1 and the main PCB board.

[0054] Specifically, an exhaust groove 21 is provided on the rubber sleeve 2 at the LED lamp board connection end 11. The opening direction of the exhaust groove 21 faces the LED lamp board connection end 11. When the pin header body 1 is electrically connected to the LED lamp board based on the LED lamp board connection end 11, the rubber sleeve 2 at the LED lamp board connection end 11 is in contact with the LED lamp board, which can limit and support the pin header body 1 and improve the connection reliability between the pin header body 1 and the LED lamp board.

[0055] Further, the groove depth of the exhaust groove 21 is h2, and the value range of h2 is: 0.2 mm ≤ h2 ≤ 1 mm. When the LED lamp board connection end 11 of the pin header body 1 is welded to the LED lamp board, the welding hole on the LED lamp board corresponding to the LED lamp board connection end 11 is prone to heat expansion, resulting in the rise of gas. Based on the exhaust groove 21, the rising gas at the connection position between the pin header body 1 and the LED lamp board can be guided, avoiding the situation of the pin header being ejected and reducing the void ratio inside the hole, thereby improving the connection stability and electrical performance between the pin header body 1 and the LED lamp board.

[0056] Specifically, please refer to Figure 6, the bending position 13 includes four bending parts, and the pin header body 1 forms an arcuate structure based on the four bending parts. Based on the arcuate structure, the LED lamp board connection end 11 and the main PCB board connection end 12 of the pin header body 1 can be kept on the same axis to meet the electrical connection requirements of the LED lamp board and the main PCB board. At the same time, the structural rigidity of the pin header body 1 is reduced, the risk of breakage or detachment of the pads of the bent pin header on the LED lamp board and the main PCB board is reduced, and the electrical performance stability between the bent pin header and the LED lamp board and the main PCB board is improved.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope.
