Description

Technical Field

[0001] The utility model relates to the technical field of PIN needles, in particular to an integrated crimped PIN needle. Background Art

[0002] Integrated press-fit PIN technology is a connection technology for printed circuit boards. By pressing a PIN into a plated through-hole on the PCB, the PIN's unique structure elastically deforms during the press-fit process, generating a persistent normal force on the PCB's plated through-hole. This creates a stable electrical and mechanical connection without soldering. Due to its high connection reliability, lead-free environmental requirements, and convenient replacement and maintenance, this technology is widely used in key equipment such as automotive sensors, electronic control units, and anti-lock braking systems / electronic stability programs.

[0003] Press-fit PIN pins are prone to irreversible damage when repeatedly plugged and unplugged or when operating in high, low, and vibration environments.

[0024] See also Figure 1-4 , the utility model provides a technical solution:

[0025] An integrated crimped PIN needle comprises a foot base 1 and an inner core assembly 2, the top of the foot base 1 is fixedly connected to the inner core assembly 2, the outer side of the inner core assembly 2 is fitted with the inner side of the pin assembly 3, the inner core assembly 2 comprises a stabilizing column 21, the outer side of the stabilizing column 21 is fixedly connected to a first limiting plate 22, the bottom end of the first limiting plate 22 is fixedly connected to a spring 23, the top of the stabilizing column 21 is fixedly connected to a power-on cone 24, the outer side of the power-on cone 24 is fixedly connected to a spring plate 25, the pin assembly 3 comprises an insert tube 31, an inner side of the insert tube 31 is provided with a movable groove 32, an inner side of the lower end of the insert tube 31 is provided with a column groove 34, the inner side of the column groove 34 provided in the insert tube 31 is fixedly connected to a second limiting plate 33, a reserved screw hole 35 is penetrated through the lower end of the insert tube 31, a bolt 36 is spirally fitted inside the reserved screw hole 35 provided in the insert tube 31, a sleeve column 37 is spirally fitted on the outer side of the bolt 36, and a buffer channel 38 is provided on the inner side of the sleeve column 37.

[0026] As a further implementation of this solution, the outer side of the foot 1 is provided with corrugations, and the top end of the foot 1 is fixedly connected to the bottom end of the stabilizing column 21. The stabilizing column 21 is cylindrical in shape, which increases the friction with the external equipment, thereby enhancing the stability of the connection. At the same time, the corrugated structure also helps to disperse stress and reduce deformation caused by external forces.

[0027] As a further implementation of this solution, the first limiting plate 22 is shaped like a hollow cylinder. The diameter of the first limiting plate 22 is smaller than the diameter of the column groove 34. The diameter of the stabilizing column 21 is smaller than the diameter of the buffer channel 38. The sleeve 37 is sleeved on the outside of the stabilizing column 21. The cylindrical shape helps to evenly distribute pressure and reduce local stress concentration, thereby protecting the root of the PIN needle from damage and extending the service life of the device. The sleeve 37 is sleeved on the outside of the stabilizing column 21 to prevent the sleeve 37 from detaching from the inner core assembly 2.

[0028] As a further implementation of this solution, the bottom end of the spring 23 is fixed to the top end of the sleeve 37, and the energizing cone 24 is in the shape of a quadrangular pyramid. The energizing cone 24 moves inside the movable groove 32 provided in the insert 31. The energizing cone 24 provides good structural stability, and its sharp apex helps to accurately position itself inside the insert 31, ensuring accurate assembly of the device.

[0029] As a further implementation of this solution, the spring plates 25 are arc-shaped, and there are four of them. The outer sides of the spring plates 25 fit into the inner sides of the movable grooves 32 defined in the insert 31. The arc-shaped spring plates 25 help disperse pressure and reduce local stress concentration. Furthermore, the arc-shaped structure provides good elastic recovery when compressed, helping to maintain the stability of the electrical connection.

[0030] As a further implementation of this solution, the foot 1, the stabilizing column 21, the energizing cone 24, and the spring plate 25 are electrically connected. The spring plate 25 is electrically connected to the insert 31. The movable groove 32 is formed in a conical shape, and the column groove 34 is formed in a cylindrical shape. The movable groove 32 and the column groove 34 are connected. This electrical connection design ensures the integrity of the electrical connection within the device and helps to achieve efficient signal transmission.

[0031] As a further implementation of this solution, the second limit plate 33 is shaped like a hollow cylinder. The diameter of the inner through hole of the second limit plate 33 is smaller than the diameter of the outer side of the first limit plate 22. There is a distance between the second limit plate 33 and the first limit plate 22. The sleeve 37 is fixed to the insert 31 by bolts 36. A threaded hole is provided on the inner side of the sleeve 37. The number of bolts 36 corresponds one-to-one to the number of reserved screw holes 35. The cone-shaped movable groove 32 helps to guide and position the insertion of the device. At the same time, the cone structure can provide good elastic recovery when subjected to pressure, which helps to maintain the stability of the device. It also has a detachable function, which is convenient for later external or upper end device replacement of the sleeve 37.

[0032] Working process: When installing the device, the sleeve 37 is sleeved on the outside of the stabilizing column 21. The sleeve 37 cannot be separated from the inner core component 2. Under the action of the spring 23, the first limit plate 22 maintains a certain distance from the sleeve 37. The energizing cone 24 is placed inside the movable groove 32 opened in the insert 31, so that the threaded hole opened in the sleeve 37 is aligned with the reserved screw hole 35 opened in the insert 31. When the sleeve 37 fits with the bottom end of the insert 31, the sleeve 37 and the insert 31 are fixed by the bolt 36. At this time, the outer side of the spring plate 25 is in contact with the insert The inner side of the movable groove 32 opened by the tube 31 is tightly attached, and the spring plate 25 undergoes a certain deformation under the action of the pressure of the insert tube 31. At this time, the foot 1, the energized cone 24, the spring plate 25 and the insert tube 31 are electrically connected, the stabilizing column 21 and the sleeve 37 are separated, the first limit plate 22 and the insert tube 31 are separated, and a gap is set between the first limit plate 22 and the second limit plate 33. When the foot 1 is welded and fixed to the external circuit board, when the device is repeatedly plugged in and out of the external device, or is subjected to external vibration, the insert tube 31 is plugged in and out of the external device. At this time, the foot 1 The inner core assembly 2 and the pin assembly 3 act as a conductive medium to realize signal transmission. When external activity occurs, the plug 31 will move with the external device. Under the elastic action of the spring plate 25, it can buffer the force applied to the plug 31 in the horizontal direction. The spring plate 25 is deformed, and the spring plate 25 also plays a role in conducting the circuit. When the plug 31 moves up and down with the external device, the spring 23 moves up and down with the sleeve 37 and the plug 31. The spring 23 elastically stretches or contracts, and the first limit plate 22 moves on the plug. Inside the column groove 34 opened in the cylinder 31, there is a certain distance between the stabilizing column 21 and the sleeve column 37, which plays a role in providing a certain movable spacing between the inner core component 2 and the pin component 3. The second limit plate 33 and the first limit plate 22 play a role in limiting the moving distance between the inner core component 2 and the pin component 3, thereby reducing the effect of deformation of the foot 1, inner core component 2 and pin component 3 caused by external forces due to the effect of external buffering. At the same time, the device has a detachable function, which is convenient for later external replacement or replacement of the upper end device of the sleeve column 37.
