[0028] First embodiment
[0029] Figures 1A to 1H Schematic diagram of a cantilever beam connector according to a first embodiment of the present disclosure. According to a first embodiment of the present disclosure, a cantilever beam connector is provided, which is configured to achieve electrical connection between an electrical component and a pad of a PCB board. As shown in the figure, the cantilever beam connector of this embodiment mainly includes a base 1 and a cantilever beam terminal 2. The base 1 is made of an insulating material. Preferably, the base 1 can be made of plastic. The cantilever beam terminal 2 is made of metal and has good electrical conductivity.
[0030] like Figure 1C to Figure 1F as well as Figure 1H As shown, the cantilever beam terminal 2 includes a first section 21, a second section 22 and a third section 23. The first section 21 is provided in the base 1 in an integrally formed manner and is configured to be electrically connected to the electrical component. Preferably, the first section 21 can be provided in the base 1 made of plastic in an injection molding manner. The second section 22 is provided between the first section 21 and the third section 23 and can be elastically deformed to be in a free state (see Figure 1C , Figure 1D ) and compressed state (see Figure 1E , Figure 1F The third section 23 is configured to abut against the pad 3 of the PCB board when the second section 22 is in a compressed state.
[0031] Because the first section 21 of the cantilever beam terminal 2 is integrally formed in the base 1, the electrical connection between the electrical component and the pad 3 of the PCB can be conveniently and reliably achieved by using only the cantilever beam connector, without using any additional parts, assembly process and assembly equipment. Therefore, not only a higher integration level can be achieved, but also the cost can be effectively reduced.
[0032] like Figures 1A to 1F As shown, the base 1 may be provided with shoulders 11 on both sides of the cantilever beam terminal 2 to limit the displacement of the cantilever beam terminal 2 when the second section 22 of the cantilever beam terminal 2 is elastically deformed.
[0033] Those skilled in the art should understand that the shape, thickness, material, and displacement stroke of the cantilever beam terminal 2 can be selected according to the required elastic force of the elastic deformation to ensure the reliability of the electrical connection.
[0034] Those skilled in the art should understand that the structure of the first section 21 of the cantilever beam terminal 2 integrally formed in the base 1 is not restricted, and the position of the connecting end of the first section 21 and the connecting end of the third section 23 can be flexibly set to provide sufficient freedom for the layout of the PCB board and internal electrical components.
[0035] Specifically, in this embodiment, Figure 1C to Figure 1E as well as Figure 1H As shown, the connection end of the first section 21 of the cantilever beam terminal 2 can be a disc-shaped end. Alternatively, the connection end of the first section 21 of the cantilever beam terminal 2 can be a block-shaped end, or it can also be set to other suitable shapes according to the internal electrical components. The second section 22 of the cantilever beam terminal 2 can include one or more bending sections. The connection end of the third section 23 of the cantilever beam terminal 2 can be a needle-shaped end. Alternatively, the connection end of the third section 23 of the cantilever beam terminal 2 can be a disc-shaped end, or it can also be set to other suitable shapes according to the docking PCB pad.
[0036] In addition, if Figure 1F and Figure 1G as well as Figure 3A As shown, the cantilever beam connector may further include a protective cap 4. The protective cap 4 can be detachably connected to the base 1 and is configured to cover and protect the cantilever beam terminal 2 of the connector. Thus, during the production, transportation, and testing of the connector, the protective cap 4 can protect the cantilever beam terminal 2. Before installing and using the connector, the protective cap 4 can be disassembled and removed from the base 1.
[0037] Second embodiment

According to the second embodiment of the present disclosure, a cantilever beam connector is provided, which is configured to achieve electrical connection between an electrical component and a pad of a PCB board. As shown in the figure, the cantilever beam connector of this embodiment mainly includes a base 100 and a cantilever beam terminal 200. The base 100 is made of an insulating material. Preferably, the base 100 can be made of plastic. The cantilever beam terminal 200 is made of metal and has good electrical conductivity.
[0039] like Figure 2C to Figure 2F as well as Figure 2H As shown, the cantilever beam terminal 200 includes a first section 201, a second section 202 and a third section 203. The first section 201 is provided in the base 100 in an integrally formed manner and is configured to be electrically connected to the electrical component. Preferably, the first section 201 can be provided in the base 100 made of plastic in an injection molding manner. The second section 202 is provided between the first section 201 and the third section 203 and can be elastically deformed to be in a free state (see Figure 2C , Figure 2D ) and compressed state (see Figure 2E , Figure 2F The third section 203 is configured to abut against the pad 300 of the PCB board when the second section 202 is in a compressed state.
[0040] Because the first section 201 of the cantilever beam terminal 200 is integrally formed in the base 100, the electrical connection between the electrical component and the pad 300 of the PCB can be conveniently and reliably achieved by using only the cantilever beam connector, without using any additional parts, assembly process and assembly equipment. Therefore, not only a higher integration level can be achieved, but also the cost can be effectively reduced.
[0041] like FIG. 2A to FIG. 2F As shown, the base 100 may be provided with shoulders 101 on both sides of the cantilever beam terminal 200 to limit the displacement of the cantilever beam terminal 200 when the second section 202 of the cantilever beam terminal 200 is elastically deformed.
[0042] Those skilled in the art should understand that the shape, thickness, material, and displacement stroke of the cantilever beam terminal 200 can be selected according to the required elastic force of the elastic deformation to ensure the reliability of the electrical connection.
[0043] Those skilled in the art should understand that the structure of the first section 201 of the cantilever beam terminal 200 integrally formed in the base 100 is not restricted, and the position of the connecting end of the first section 201 and the connecting end of the third section 203 can be flexibly set to provide sufficient freedom for the layout of the PCB board and internal electrical components.
[0044] Specifically, in this embodiment, FIG. 2C to FIG. 2E as well as Figure 2H As shown, the connection end of the first section 201 of the cantilever beam terminal 200 can be a needle-shaped end. Alternatively, the connection end of the first section 201 of the cantilever beam terminal 200 can be a block-shaped end, or it can also be set to other suitable shapes according to the internal electrical components. The second section 202 of the cantilever beam terminal 200 can include one or more bending sections. The connection end of the third section 203 of the cantilever beam terminal 200 can be a bent end. Alternatively, the connection end of the third section 203 of the cantilever beam terminal 200 can be a disc-shaped end, or it can also be set to other suitable shapes according to the docking PCB pad.
[0045] In addition, if Figure 2F and Figure 2G as well as Figure 3B As shown, the cantilever beam type connector may further include a protective cap 400. The protective cap 400 can be detachably coupled to the base 100 and is configured to cover and protect the cantilever beam terminal 200 of the connector. Thus, during the production, transportation, and testing of the connector, the protective cap 400 can protect the cantilever beam terminal 200. Before installing and using the connector, the protective cap 400 can be disassembled and removed from the base 100.
[0046] Compared with existing connectors, the cantilever beam connector disclosed in the present invention can provide a safe and reliable electrical connection between an electrical component and a pad of a PCB without requiring additional parts, assembly processes, and assembly equipment, thereby achieving not only a higher level of integration but also effectively reducing costs.
