Technical Field
[0001] This utility model relates to circuit boards, and more particularly to circuit boards with displays. Background Technology
[0002] The primary purpose of circuit boards is to provide connections and support for electrical components and to enable circuit functionality. Circuit boards are widely used in various electronic devices, including computers, communication equipment, consumer electronics, industrial control systems, and medical devices. Different types of circuit boards are suitable for different application scenarios, and the selection should be based on specific requirements.
[0003] Circuit boards are often used in conjunction with displays. Currently, displays and circuit boards are often connected using metal pins, which involves inserting the pins into the circuit board and then soldering them to connect the circuit.
[0004] This method requires soldering on the circuit board, so the soldering process must be carried out without affecting the circuit board circuit. The soldering process is quite strict. In addition, the pins need to be perfectly aligned with the position of the insertion hole. If there is a positional deviation due to manufacturing precision, it will result in the inability to insert. Even if it is inserted after bending, the bent parts of the pins at both ends will be exposed, affecting the stability of the installation. Utility Model Content
[0005] In view of the shortcomings of existing technologies, such as the high requirements for welding process when pins are directly inserted and soldered, and the inability to connect when manufacturing precision problems occur, this utility model provides a circuit board with a display screen.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

The display screen assembly includes a mounting frame, a display screen disposed on the top surface of the mounting frame, and a base disposed on the bottom surface of the mounting frame. The mounting frame is detachably connected to the circuit board and presses the base together when connected. The display screen has two pins. The base has two lead through holes and four cross-shaped grooves. The four grooves converge at the bottom of the lead through holes. The pins pass through the lead through holes and are bent into one of the grooves for soldering. After being bent again, they are inserted into the insertion holes.
[0008] Preferably, the mounting frame is provided with a plug pin, and the bottom of the plug pin is provided with a bend. After the plug pin passes through the mounting hole, the bend is bent so that the bend is offset from the mounting hole and abuts against the bottom surface of the circuit board.
[0009] Preferably, the mounting holes are provided in two rows, all of which are strip-shaped holes, and the plug pins correspond one-to-one with the mounting holes.
[0010] Preferably, the mounting frame is a metal frame with extendable pins.
[0011] Preferably, the bottom of the mounting frame is provided with a groove, the middle of the groove is provided with a display hole, the display screen is embedded in the groove and its display area is located below the display hole.
[0012] Preferably, the top of the base is embedded in the groove, and the bottom of the base abuts against the top surface of the circuit board.
[0013] Preferably, the base includes a strip plate and front and rear pads disposed on the front and rear sides of the strip plate, the tops of the front and rear pads abutting against the front and rear edges of the display screen, and there is a gap between the strip plate and the bottom surface of the display screen.
[0014] Preferably, the diameter of the lead wire through hole gradually decreases from top to bottom.
[0015] Preferably, the minimum diameter of the lead-through hole is the same as the diameter of the pin.
[0016] Preferably, the groove depth is greater than or equal to the pin diameter, and the groove width is greater than the pin diameter.
[0017] Compared with the prior art, the advantages of this utility model are as follows: This application sets a base to pass the pin through the lead wire through hole and then bend it into the groove. When there is a size deviation, it is only necessary to change the length of the pin bent into the groove, so as to ensure that the deviation is compensated before being inserted into the plug hole without the pin being exposed. In addition, after the pin is plugged in, it is only necessary to fix the mounting frame in the mounting hole, without the need for soldering. Attached Figure Description

[0026] Example
[0027] This embodiment mainly describes the title of the circuit board with a display screen, as follows:
[0028] Main scheme :
[0029] Circuit boards with displays, such as Figure 1-4 As shown, the assembly includes a circuit board 10 and a display screen 40. The circuit board 10 has insertion holes and mounting holes 101. The display screen 40 assembly includes a mounting frame 30, a display screen 40 disposed on the top surface of the mounting frame 30, and a base 20 disposed on the bottom of the mounting frame 30. The mounting frame 30 is detachably connected to the circuit board 10, and when connected, it presses the base 20 tightly. The display screen 40 has two pins, the pin structure of which is not shown in the figure. The base 20 has two lead wire through holes 204 and four cross-shaped grooves 205. The four grooves 205 converge at the bottom of the lead wire through holes 204. The pins pass through the lead wire through holes 204 and are bent into one of the grooves 205 for soldering. After being bent again, they are inserted into the insertion holes. This solution uses a base 20 to pass the pin through the lead wire through hole 204 and then bend it into the groove 205. When there is a dimensional deviation, the length of the pin bent into the groove 205 can be changed to ensure that the deviation is compensated before being inserted into the socket without the pin being exposed.
[0030] Mounting frame fixing part :
[0031] like Figure 2As shown, the mounting frame 30 is provided with a connector 301. The bottom of the connector 301 has a bent portion. After the connector 301 passes through the mounting hole 101, it bends the bent portion so that the bent portion deviates from the mounting hole 101 and abuts against the bottom surface of the circuit board 10. The connector 301 is used to fix the mounting frame 30 to the circuit board 10. This structure does not require soldering.
[0032] like Figure 2 and 4 As shown, the mounting holes 101 have two rows of strip-shaped holes, and the plug pins 301 correspond one-to-one with the mounting holes 101. Preferably, the width of the strip-shaped hole is slightly larger than the width of the plug pin 301, and the length of the strip-shaped hole is approximately the same as the length of the plug pin 301.
[0033] Preferably, the mounting frame 30 is a metal frame 30, and its plug pins 301 are flexible. When flexible, they can be bent directly after insertion to hook onto the bottom of the circuit board 10 for fixation.
[0034] Display screen installation section :
[0035] like Figure 3 and 4 As shown, the bottom of the mounting frame 30 is provided with a groove, and the middle of the groove is provided with a display hole 302. The display screen 40 is embedded in the groove and its display area is located below the display hole 302.
[0036] Base part :
[0037] like Figure 3 and 4 As shown, the top of the base 20 is embedded in the groove, and the bottom of the base 20 abuts against the top surface of the circuit board 10.
[0038] Preferably, the base 20 includes a strip plate 201 and front pads 202 and rear pads 203 disposed on the front and rear sides of the strip plate 201. The top ends of the front pads 202 and rear pads 203 abut against the front and rear edges of the display screen 40, and there is a gap between the strip plate 201 and the bottom surface of the display screen 40. This gap is used to improve the heat dissipation performance of the structure and increase its service life.
[0039] Preferably, the diameter of the lead hole 204 gradually decreases from top to bottom. This structure facilitates pin penetration through the hole 204.
[0040] Preferably, the minimum diameter of the lead-through hole 204 is the same as the diameter of the lead. This structure provides a limiting effect at the bend after the lead is inserted and bent, preventing the lead from being pulled out directly.
[0041] Preferably, the depth of the groove 205 is greater than or equal to the diameter of the pin, and the width of the groove 205 is greater than the diameter of the pin. The groove 205 hides the pin inside in the depth direction to avoid exposure, while the space left in the width direction is used for soldering.
[0042] The title provided above provides a detailed description of the present utility model. Specific examples have been used to illustrate the principles and implementation methods of the present utility model. The description of the above embodiments is only for the purpose of helping to understand the present utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present utility model without departing from the principles of the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
