Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB bare board technology, specifically a circuit connection module based on PCB bare board. Background Technology
[0002] The circuit connection module of a bare PCB refers to the structure and area on a printed circuit board used to realize the electrical connection between different electronic components. It is usually composed of conductive copper foil lines, pads, vias, etc. These elements are formed on an insulating substrate through processes such as etching to build the circuit path and ensure that the current can flow between the various components according to the designed path, thereby realizing the control function of electronic equipment.
[0003] When installing circuit components on a bare PCB, improper operation can easily cause the component leads to bend or break. Taking small integrated circuit chips as an example, the leads of these chips are usually small and fragile. In order to easily insert the component leads into the holes of the bare PCB, tweezers are needed. If the tweezers or other tools are used improperly during the installation process, such as using too much force, inaccurate gripping position, or having burrs on the tweezers tip, the leads may be damaged, causing them to bend or even break, ultimately rendering the component unusable and damaged. Therefore, a circuit connection module based on a bare PCB is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0026] Please see Figure 1-6 This utility model provides a technical solution:
[0027] A circuit connection module based on a bare PCB board includes a bare PCB board assembly 1, the inner side of which is attached to the outer side of a frame assembly 2. A welding auxiliary assembly 3 is fixedly connected to one side of the frame assembly 2. The frame assembly 2 includes a base plate 21, a guide post 22 is fixedly connected to the top of the base plate 21, an operation groove 23 is opened on the inner side of the base plate 21, and a support crossbeam 24 is fixedly connected to the inner side of the operation groove 23. The welding auxiliary assembly 3 includes a metal sleeve 31, a crack 32 and a welding hole 33 are opened on the inner side of the metal sleeve 31, an anti-detachment ring 34 is fixedly connected to the top of the metal sleeve 31, a vent hole 35 and a vent groove 36 are opened on the inner side of the anti-detachment ring 34, a metal stripe 37 is fixedly connected to the inner side of the metal sleeve 31, and the bottom end of the metal sleeve 31 is fixedly connected to the top end of the support crossbeam 24.
[0028] As a further implementation of this solution, the bare PCB assembly 1 includes a bare PCB body 11. The bare PCB body 11 has pin insertion holes 12 on its inner side and fixed reserved holes 13 near the four corners. Guide posts 22 slide inside the fixed reserved holes 13. The number of guide posts 22 is the same as the number of fixed reserved holes 13. Through the above arrangement, the design of installing guide posts 22 inside the fixed reserved holes 13 improves the stability of the connection between the frame assembly 2 and the bare PCB assembly 1, and at the same time provides guidance when the base plate 21 moves downward.
[0029] As a further implementation of this solution, there are multiple support crossbeams 24, the operating groove 23 extends vertically through the inner side of the base plate 21, and there is a gap between the support crossbeams 24. Through the above settings, the design of the operating groove 23 and the gap between the multiple support crossbeams 24 provides operating space for welding.
[0030] As a further implementation of this solution, the number of welding auxiliary components 3 is the same as the number of pin sockets 12. The welding auxiliary components 3 are embedded inside the pin sockets 12, with the upper end of the welding auxiliary components 3 protruding from the upper end of the pin sockets 12. The cracks 32 penetrate the inner side of the metal sleeve 31 vertically. Multiple cracks 32 are opened inside the metal sleeve 31, which is shaped as a hollow cone. The welding holes 33 penetrate the interior of the metal sleeve 31. Through the above-mentioned design, the auxiliary design of the welding auxiliary components 3 provides convenience for inserting the pins of components into the pin sockets 12, while not affecting the electrical connection between the pins of components and the internal circuit of the PCB bare board body 11. At the same time, the welding holes 33 penetrate the interior of the metal sleeve 31, providing a channel for the flow of solder during welding, ensuring the strength and reliability of the welding, and effectively improving the welding quality.
[0031] As a further implementation of this solution, the vent groove 36 penetrates the outer side of the anti-detachment ring 34. The diameter of the anti-detachment ring 34 is 1.2 times the diameter of the pin socket 12. The vent hole 35 is connected to the vent groove 36. Both the vent hole 35 and the vent groove 36 penetrate the interior of the anti-detachment ring 34 vertically. Through the above arrangement, the vent groove 36 penetrates the anti-detachment ring 34 and is connected to the vent hole 35. The design of the vent hole 35 and the vent groove 36 penetrating the interior of the anti-detachment ring 34 forms a good heat dissipation channel, which can dissipate the heat generated by the components during the soldering process in a timely manner and prevent the components from being damaged due to overheating. The diameter design of the anti-detachment ring 34 prevents the metal sleeve 31 from detaching from the inside of the pin socket 12.
[0032] Workflow: When soldering circuit components onto the bare PCB board, first insert the pins of the circuit components into the corresponding metal sleeves 31, placing the circuit components on top of the anti-detachment rings 34. The anti-detachment rings 34 support the circuit components. After all the circuit components are inserted into the metal sleeves 31, press down on the guide posts 22. The base plate 21 moves the guide posts 22 and the operating grooves 23 downwards, and the support crossbar 24 moves the metal sleeves 31 downwards. Because the upper diameter of the metal sleeve 31 is larger than the lower diameter... With a smaller diameter, as the metal sleeve 31 moves downwards, its outer side will be in close contact with the pin socket 12. Due to the pressure from the pin socket 12, the upper end of the metal sleeve 31 gradually moves inwards, causing the metal stripe 37 to come into close contact with the component's pins. The metal stripe 37 increases the friction between the metal sleeve 31 and the component's pins. Simultaneously, the metal stripe 37 serves as the medium for electrical connection between the metal sleeve 31 and the component's pins. When the bottom end of the anti-detachment ring 34 is in contact with the top end of the PCB bare board body 11, the vent hole 35 and the vent groove 36... The device serves to dissipate heat generated by the components. At this time, the outer side of the metal sleeve 31 is tightly attached to the inside of the pin socket 12, while the pins of the components are tightly attached to the inside of the metal strip 37. The friction force fixes the pins of the components. Then, the entire device is flipped so that the base plate 21 faces upward. The components are soldered through the operating slot 23. During soldering, the metal sleeve 31 is electrically connected to the circuit inside the bare PCB board 11. Solder enters the inside of the metal sleeve 31 through the soldering hole 33, thereby fixing the pins of the components, the metal sleeve 31, and the bare PCB board 11, thus completing the soldering work. After soldering, the metal sleeve 31 and the pins of the components are cut with scissors, and the guide post 22 is removed from the fixed reserved hole 13. Based on the above principles, the device provides convenience for the insertion of component pins through the flared design of the metal sleeve 31, without the need for tools. This significantly reduces the probability of damage when components are installed inside the pin socket 12. This soldering method provides convenience for operators.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
