Detailed Description
The present invention will be described in further detail with reference to the following examples, which are illustrative of the present invention and are not intended to limit the present invention.
Embodiment 1, a PCB for installing a connection terminal, as shown in fig. 1, the connection terminal (a 90 ° bent-seat fence type connection terminal) includes a terminal body 20 and a pin 21, the PCB includes a PCB body 10 and a terminal mounting hole 11 disposed on the PCB body 10, the pin 21 is connected to the PCB body 10 through the terminal mounting hole 11, that is, after the pin 21 passes through the mounting hole, the pin 21 is soldered in the mounting hole, and at this time, the terminal body 20 is installed on the PCB body 10 through the pin 21, and is further connected to a circuit on the PCB body 10 through the pin 21.
As shown in fig. 2, in the present embodiment, a support member 12 is disposed on the PCB body 10, and the support member 12 is located between the terminal mounting hole 11 and the terminal body 20 and is used for supporting the pin 21.
In this embodiment, the supporting member 12 is a supporting block 120, the supporting block 120 is fixed (e.g., welded) on the PCB body 10, located between the terminal mounting hole 11 and the terminal body 20, and is used for supporting the bent pin 21, and the supporting block 120 can assist the bent pin 21 to resist external impact and prevent deformation or fracture.
The supporting member 12 includes a supporting block 120 and a plurality of limiting protrusions 121 disposed on the supporting block 120, as shown in fig. 4, the limiting protrusions 121 are inserted between two adjacent pins 21 to limit the pins 21 from contacting each other.
Through the comb-shaped design of the supporting member 12, the pins 21 are separated by the limiting protrusions 121, so that when the pins 21 are deformed, the circuit on the PCB cannot work normally due to the contact of the two pins 21.
As shown in fig. 3, in this embodiment, when the pin 21 is a bent pin 21, a notch 13 may be further disposed at an edge of the PCB body 10, the terminal body 20 is disposed at the notch 13, and a side wall of the terminal body 20 is attached to a surface of the notch 13, so as to improve the external force resistance of the connection terminal.
As shown in fig. 4, in this embodiment, the notch 13 is a concave notch adapted to the terminal body 20, and can effectively limit the terminal body 20 from moving left and right in the notch 13.
Because the shape of the welding section (i.e., the vertical section pin 21 inserted into the terminal mounting hole 11) between the bent pin 21 and the PCB body 10 is wide at the top and narrow at the bottom, when the terminal body 20 is located at the notch 13 and the side wall of the terminal body 20 is attached to the surface of the notch 13, the distance that the bent pin 21 is higher than the top surface of the PCB body 10 is reduced, and at this time, the wider part of the welding section is inserted into the terminal mounting hole 11 and connected to the PCB body 10. Therefore, in this embodiment, the diameter of the terminal mounting hole 11 is 2mm to 3mm, specifically 2.5mm, so that the wider portion of the soldering section is inserted into the terminal mounting hole 11 and is firmly soldered to the PCB body 10.
The PCB body 10 is further provided with a limiting frame, the limiting frame is located above or below the terminal body 20 and is abutted against the terminal body 20, and therefore the auxiliary wiring terminal resists upward or downward external force.
In this embodiment, the PCB body 10 at both sides of the concave notch is symmetrically provided with the limiting frame mounting holes 14;
as shown in fig. 6, the limiting frame includes a blocking plate 151 and a connecting portion 152 disposed on the blocking plate 151, as shown in fig. 7, the connecting portion 152 corresponds to the limiting frame mounting hole 14 one by one, the connecting portion 152 is connected to the PCB body 10 through the limiting frame mounting hole 14, at this time, the blocking plate 151 is directly opposite to the concave notch, and the blocking plate 151 abuts against the terminal body 20.
In summary, in the present embodiment, through the design of the supporting member 12, on one hand, the bent pins 21 can be supported to avoid deformation thereof, and on the other hand, each adjacent pin 21 is separated by the limiting protrusion 121 to avoid the pins 21 contacting with other pins 21 when deforming; through the design of the shape of the PCB body 10, one side of the terminal body 20 extending out of the pin 21 can be abutted against the PCB body 10, so that the external force resistance of the terminal body is improved; through the design of the limiting frame, the terminal body 20 in the notch 13 can be limited to move upwards or downwards, and the capacity of resisting external force is further improved.
In addition, it should be noted that the specific embodiments described in the present specification may differ in the shape of the components, the names of the components, and the like. All equivalent or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model.
