Description

Technical Field

[0001] This utility model relates to the field of electronic component connection technology, specifically a quick connection structure between a PCBA board and a copper busbar. Background Technology

[0002] In electronic devices, the effective connection between PCBA boards and copper busbars is crucial. Currently, traditional connection methods mainly include soldering and screw fixing. However, both of these methods have obvious drawbacks.

[0003] In terms of welding methods, the process is relatively complex and inefficient. In actual operation, welding quality is affected by a variety of factors, such as welding technology and operator skill level, which can easily lead to quality problems such as incomplete welding and false welding. These quality problems may cause electrical faults during equipment operation, seriously affecting the stability and reliability of the equipment.

[0004] While screw fastening provides a certain degree of connection strength, the process is extremely cumbersome. Each connection or disassembly requires tools such as screwdrivers, which is not only time-consuming and labor-intensive but also inefficient. More importantly, neither of these traditional connection methods allows for quick disassembly during equipment maintenance or repair, causing significant inconvenience and increasing maintenance and time costs. Therefore, developing a quick-connect structure for PCBA boards and copper busbars that overcomes these problems is of significant practical importance. Utility Model Content

[0007] The connection terminal is provided on the PCBA board, and the connection terminal includes at least two conductive pins;

[0008] The connection slot is provided on the copper busbar, and the connection slot is inserted into the connection terminal. The lower end of the connection slot is provided with a groove, which is sleeved with the connection terminal. A conductive spring corresponding to the conductive pin is provided in the groove.

[0009] The locking mechanism is installed on both sides of the connecting terminal and is used to lock and fix the connected terminal to the connecting slot after it is plugged in.

[0010] As a preferred embodiment of this utility model, the locking mechanism includes a support and a vertical plate. The support is fixedly installed on the side of the connecting terminal. The middle position of the vertical plate is rotatably connected to the support through a rotating shaft. The rotating shaft is also equipped with a torsion spring to provide locking force for the locking mechanism. A hook is fixedly installed at the upper end of the vertical plate. The two sides of the groove are provided with slots corresponding to the hook. The hook and the slot engage with each other.

[0011] As a preferred embodiment of this utility model, the upper surface of the hook is set as an inclined surface.

[0012] As a preferred embodiment of this utility model, the locking mechanism is symmetrically arranged in two parts.

[0013] As a preferred embodiment of this utility model, the outer edge of the groove opening is provided with a beveled mounting surface, which is used to reduce friction and facilitate assembly.

[0014] As a preferred embodiment of this utility model, the surfaces of the connecting terminal and the connecting slot are both provided with an anti-oxidation coating.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. By connecting the terminals and slots, and by quickly locking and unlocking the locking mechanism, PCBA boards and copper busbars can be easily connected and disconnected, greatly improving production efficiency and saving a lot of time during equipment maintenance and repair.

[0017] 2. The combination of plug-in and locking mechanisms not only ensures the stability of the electrical connection with conductive springs, but also prevents the connection from loosening, ensuring the reliability and stability of the connection during equipment operation.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, a specific embodiment of the quick connection structure between a PCBA board and a copper busbar according to this utility model includes:

[0027] The connection terminal 2 is provided on the PCBA board and includes at least two conductive pins 8; these conductive pins 8 are used to realize the electrical connection between the PCBA board and the copper busbar to ensure that the current can be transmitted stably.

[0028] The connection slot 1 is provided on the copper busbar and is inserted into the connection terminal 2. The lower end of the connection slot 1 is provided with a groove 7, which is sleeved with the connection terminal 2. The groove 7 is provided with a conductive spring 9 corresponding to the conductive pin 8. When the connection terminal 2 is inserted into the connection slot 1 and sleeved with the groove 7, the conductive spring 9 contacts the conductive pin 8 to achieve electrical connection. At the same time, the conductive spring 9 can also provide a certain elastic pressure to ensure the stability of the connection.

[0029] Two locking mechanisms 4 are symmetrically arranged and installed on both sides of the connecting terminal 2, respectively, to lock and fix the connected terminal 2 to the connecting slot 1 after insertion. The locking mechanism 4 includes a support 3 and a vertical plate. The support 3 is fixedly installed on the side of the connecting terminal 2. The middle position of the vertical plate is rotatably connected to the support 3 through a rotating shaft. The rotating shaft is also equipped with a torsion spring to provide locking force for the locking mechanism 4. A hook 5 is fixedly installed at the upper end of the vertical plate. The two sides of the groove 7 are provided with slots 6 corresponding to the hook 5. The hook 5 and the slot 6 engage and cooperate. When the connecting terminal 2 is inserted into the connecting slot 1, the hook 5 automatically engages into the slot 6 under the action of the torsion spring, realizing the connection locking. When disassembly is required, the force of the torsion spring is overcome, and the vertical plate is rotated to make the hook 5 disengage from the slot 6.

[0030] The upper surface of the hook 5 is set as a bevel; this design makes it easier for the hook 5 to slide into the slot 6 when the connecting terminal 2 is inserted into the connecting slot 1, without the need to manually adjust the position of the hook 5, thus improving the convenience of the connection operation.

[0031] The groove 7 has a beveled mounting surface 10 on its outer edge. The beveled mounting surface 10 is used to reduce friction and facilitate fitting.

[0032] Both the connecting terminal 2 and the connecting slot 1 are provided with an anti-oxidation coating. Due to the complex environment in which electronic equipment is used, the connection parts are easily affected by oxidation. The anti-oxidation coating can effectively protect the connecting terminal 2 and the connecting slot 1, improve the durability of the connection, and extend the service life of the equipment.

[0033] The working principle of this utility model is as follows: This utility model connects the connection terminal 2 on the PCBA board to the connection slot 1 on the copper busbar. During the insertion process, due to the inclined surface of the upper end of the hook 5 and the inclined mounting surface 10 of the groove 7, the hook 5 will automatically rotate around the pivot under the push of the connection terminal 2, compressing the torsion spring. When the connection terminal 2 is fully inserted into the groove 7 and the conductive pin 8 is in good contact with the conductive spring 9, the hook 5 will quickly lock into the corresponding slots 6 on both sides of the groove 7 under the action of the torsion spring, completing the connection locking and realizing the fast and reliable connection between the PCBA board and the copper busbar.

[0034] When disassembly is required, the operator only needs to pinch the lower end of the vertical plate with their fingers, overcome the force of the torsion spring, and rotate the vertical plate away from the connection slot 1, so that the hook 5 disengages from the slot 6, and then the connection terminal 2 can be easily pulled out from the connection slot 1 to complete the disassembly operation of the PCBA board and the copper busbar.

[0035] All components mentioned in this article are general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0036] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
