Description

Technical Field

[0001] The utility model relates to the technical field of pin row connectors, in particular to a pin row connector with bent pin welding ends. Background Art

[0002] The pin header connector with bent pin welding ends is a special electronic connector, which is mainly used for signal transmission and power connection of electronic equipment. The pin header connector is usually composed of two parts: an insulator and a pin. The insulator is used to fix the pin and isolate different circuits, and the pin is responsible for transmitting signals or power. After the pin welding ends are bent, they can better adapt to the layout on the circuit board, which is convenient for welding and connection. The pin header connector with bent pin welding ends is an important electronic connector with a unique structure and a wide range of applications. When the existing pin header connector with bent pin welding ends is connected to the external connecting wire head, it mainly relies on the friction of the pin header needle body itself. Due to the limitation of this friction, when the connecting wire head is slightly shaken by external force, it is easy to be damaged with the pin, and the connection is not tight enough, which can easily lead to circuit breaking.

[0003] After searching, the publication number CN220628257U disclosed a pin header connector with a bent soldering end of the pin, including a fixed seat and a row of pins arranged on the fixed seat, the pins including a connecting portion and a soldering portion formed by bending the connecting portion by 90°, one end of the connecting portion passing through the top surface of the fixed seat upward, and one end of the soldering portion passing through the first side surface of the fixed seat; the lower end surface of the soldering portion of each pin is located on the same horizontal plane as the bottom surface of the fixed seat, and at least two positioning columns extending vertically downward are provided on the bottom surface of the fixed seat. In the utility model, by bending the soldering portion by 90° so that its lower end surface is located on the same horizontal plane as the bottom surface of the fixed seat, the area of ​​the support region when the pin header connector is connected to the PCB circuit board can be increased, and by providing the positioning columns, the accurate positioning of the pin header connector when connected to the PCB circuit board can be ensured, and the structure is simple and practical.

[0026] Specifically, the first guide plate 8 and the second guide plate 10 have a guiding function. One side of the first guide plate 8 is in contact with the second mounting plate 4, and one side of the second guide plate 10 is in contact with the first mounting plate 3. The first guide plate 8 and the second guide plate 10 are rotatably connected to the first extrusion plate 7 and the second extrusion plate 9. When the first extrusion plate 7 and the second extrusion plate 9 are squeezed, the first guide plate 8 and the second guide plate 10 will move upward along one side of the first mounting plate 3 and the second mounting plate 4. The arrangement of the first clamping block 5 and the first clamping groove 6 facilitates the disassembly and maintenance of the second mounting plate 4.

[0027] Reference Figure 1 The supporting mechanism includes positioning columns 14, the top ends of the two positioning columns 14 are respectively fixedly connected to the middle of the lower surfaces of the two first mounting plates 3, and the bottom ends of the positioning columns 14 are installed inside the circuit board 1. Both sides of the lower surfaces of the two first mounting plates 3 are fixedly connected with bosses 13, and the lower surface of the bosses 13 is in contact with the upper surface of the circuit board 1.

[0028] Specifically, the provision of the positioning column 14 helps to ensure the accuracy of the soldering of the pin 2. The contact with the circuit board 1 through the boss 13 helps to maintain the stability of the pin 2 when installed on the circuit board 1. At the same time, it supports the left mounting block 16, the right mounting block 17 and the mounting block 18 to avoid squeezing the pin 2 and affecting the operation of the pin header connector.

One side of the left mounting block 16 and one side of the multiple mounting blocks 18 are both provided with a right card slot 20, one side of the right mounting block 17 and the other side of the multiple mounting blocks 18 are fixedly connected with a left card block 19 matching the right card slot 20, and multiple right card slots 20 and multiple left card blocks 19 are installed on both sides of the corresponding pins 2.

[0032] Specifically, when the left clamping block 19 and the right clamping slot 20 are docked, a socket is formed to facilitate the installation of the pin 2. By placing the pin 2 between the two mounting blocks 18 so that the matching left clamping block 19 and the right clamping slot 20 are docked, a single pin 2 can be fixed. By docking the left clamping blocks 19 and the right clamping slots 20 on multiple mounting blocks 18 with each other, the pin 2 is between the two mounting blocks 18. Finally, by installing the left mounting block 16 and the right mounting block 17 so that they are docked with the matching left clamping block 19 and the right clamping slot 20, multiple pins 2 can be fixed and installed.

[0033] Reference Figure 1 The lower surfaces of the two second mounting plates 4 are fixedly connected with fixing plates 21 , and the adjacent sides of the two fixing plates 21 are in contact with the two sides of the mounting block 18 .

[0034] Specifically, the provision of the fixing plate 21 helps to improve the stability of the second mounting plate 4 .

[0035] A plurality of through slots 15 are formed between the plurality of pins 2 and the mounting block 18 .

[0036] Specifically, the boss 13 supports the left mounting block 16 , the right mounting block 17 and the mounting block 18 to form the through slot 15 , which is beneficial for providing a better heat dissipation space between the bottom of the pin 2 and the circuit board 1 during welding.

[0037] Working principle: By placing the pin 2 between the two mounting blocks 18 so that the matching left card block 19 and the right card slot 20 are docked, the single pin 2 is fixed, and by docking multiple mounting blocks 18 with each other, the pin 2 is between the two mounting blocks 18, and finally by installing the left mounting block 16 and the right mounting block 17 so that they are docked with the matching left card block 19 and the right card slot 20, multiple pins 2 can be fixed and installed, which is convenient for the integrity of subsequent welding. By inserting and fixing the positioning column 14 into the positioning hole of the circuit board 1, the accuracy of welding the pin 2 is facilitated, and the contact with the circuit board 1 through the boss 13 helps to maintain the stability of the pin 2 when it is installed on the circuit board 1, and at the same time supports the left mounting block 16, the right mounting block 17 and the mounting block 18 to avoid squeezing the pin 2 and affecting the pin header connector. The boss 13 supports the left mounting block 16, the right mounting block 17 and the mounting block 18 to form a through groove 15, which is beneficial for the bottom of the pin 2 and the circuit board 1 to have a better heat dissipation space during welding. Through the installation of the second mounting plate 4, when the pin 2 is connected to the external connecting wire head, the external connecting wire head contacts the first extrusion plate 7 and the second extrusion plate 9 from the first guide plate 8 and the second guide plate 10. In this process, the connecting wire head squeezes the first extrusion plate 7 and the second extrusion plate 9 to shrink the spring 12 and the telescopic rod 11. The spring 12 has a certain tension to push the first extrusion plate 7 and the second extrusion plate 9 to limit and fix the connecting wire head, thereby effectively preventing the connecting wire head from being damaged by excessive shaking when subjected to external force, and effectively improving the tightness of the connection between the pin 2 and the connecting wire head.
