[0002] Connectors are a common component in electrical engineering. Their function is to connect circuits on different devices or different modules in a circuit, so that current or signals can flow or be transmitted, and the circuit can perform its intended function.

[0003] To achieve the transmission of multiple signals, terminal connectors are commonly used for multi-signal communication. These connectors contain conductive terminals such as 8-pin, 16-pin, 24-pin, or 32-pin pins. Not only does the number of terminals need to be adjusted according to actual application requirements, but the terminal arrangement also varies. Therefore, it is necessary to design corresponding automated production and assembly equipment to accommodate the manufacturing of various types of terminal connectors, thereby improving production efficiency.

The punching device 24 includes a punching drive device 243, multiple positioning posts 242, and at least two punching blades 241. The punching drive device 243 adopts a cam drive device, that is, a motor drives the cam to rotate, and the cam is hinged to the drive rod, thereby driving the drive rod to reciprocate in the vertical direction. The positioning posts 242 and the punching blades 241 are located below the drive rod, thus also driving the positioning posts 242 and the punching blades 241 to reciprocate in the vertical direction. The punching drive device 243 drives the punching blades 241 to move toward the terminal conveying groove 222, and the fixed base 221 is located on the side of the terminal conveying groove 222 near the feeding base 211. A cutting groove is provided, which extends vertically. The end of the cutting blade 241 can be moved into the cutting groove. When a row of conductive terminals 14 are input into the terminal conveying groove 222, at least two cutting blades 241 cut off the two connecting parts 141 respectively, so that a single conductive terminal 13 falls into the terminal conveying groove 222. Furthermore, the fixed base 221 is provided with multiple positioning holes 223 on the side of the cutting groove near the feeding base 211. The cutting drive device 243 is also connected to the positioning column 242 through the drive rod and drives the positioning column 242 to move toward the positioning hole 223. At the same time, the positioning column 242 will also be in clearance fit with the positioning hole 142 to realize the positioning of the row of conductive terminals 14.

[0034] The terminal feeding device 21 is located on the horizontal side of the insertion device 22. The terminal feeding device 21 includes a feeding base 211, a feeding drive device 215, and a terminal conveying roller 213. The feeding base 211 is provided with a terminal feeding groove 212 along the horizontal feeding direction Y. The horizontal feeding direction Y is perpendicular to the horizontal insertion direction X. The terminal feeding groove 212 is connected to the terminal conveying groove 222. The terminal feeding groove 212 is used to convey rows of conductive terminals 14. The feeding drive device 215 is a rotary motor. The feeding drive device 215 is connected to the terminal conveying roller 213 and drives the terminal conveying roller 213 to rotate. The terminal conveying roller 213 is rotatably mounted on the terminal feeding groove 212. A drive gear 214 is provided on the outer periphery of the terminal conveying roller 213. The drive gear 214 rotates on the terminal feeding groove 212. The drive gear 214 is used to cooperate with the positioning holes 142 of the rows of conductive terminals 14, thereby driving the rows of conductive terminals 14 to move along the horizontal feeding direction Y.

[0035] The housing loading device 3 includes a vertical moving device 33, a horizontal moving device 32, and a housing clamp 31. The horizontal moving device 32 is connected to the housing clamp 31 and drives the housing clamp 31 to move along the horizontal translation direction. The horizontal loading direction Y is parallel to the horizontal translation direction. The housing clamp 31 is located at the outer end of the terminal insertion slot 229. The vertical moving device 33 and the horizontal moving device 32 can each be a linear movement drive device. The horizontal moving device 32 is mounted on the vertical moving device 33. The vertical moving device 33 drives the horizontal moving device 32 and the housing clamp 31 to move along the vertical translation direction. The housing clamp 31 is used to clamp the housing 11.

[0036] During the production of the assembly terminal connector 1, rows of conductive terminals 14 are conveyed by terminal conveying rollers 213 on the terminal loading groove 212. When the rows of conductive terminals 14 are fed into the terminal conveying groove 222, the cutting blade 241 cuts off the connecting part 141, causing individual conductive terminals 13 to fall into the terminal conveying groove 222. At the same time, the housing 11 is clamped by the housing clamp 31, and driven by the vertical moving device 33 and the horizontal moving device 32, the terminal hole 12 of the housing 11 is aligned with the terminal insertion groove 22. 9. Then, the ejector pin drive device 227 drives the ejector pin 224 through the terminal delivery groove 222, and then pushes the conductive terminal 13 into the terminal insertion groove 229. Then, as the moving base 228 moves along the horizontal insertion direction X, the insertion post 230 is inserted into the terminal hole 12. Finally, the ejector pin 224 passes through the terminal insertion groove 229, and then the conductive terminal 13 passes out of the terminal insertion groove 229 and is inserted into the terminal hole 12. Repeating the above steps can complete the insertion of the conductive terminals 13 into the multiple terminal holes 12 in the housing 11.

[0037] As can be seen above, the terminal feeding groove is used to place rows of conductive terminals, while the terminal conveying roller and the gear on it are used to accurately convey the rows of conductive terminals. It works in conjunction with the cutting blade to move towards the cutting groove, and then the cutting blade cuts off individual conductive terminals in the row of conductive terminals. With the precise positioning of the positioning pin and positioning hole, the cutting accuracy is improved. After the individual conductive terminal falls into the terminal conveying groove, the conductive terminal is conveyed to the terminal insertion groove by the push of the top pin. With the movement of the moving base and the insertion pin, not only is the insertion pin aligned with the hole of the connector housing, but the conductive terminal can also be accurately pressed into the hole of the connector housing.
