[0020] The present patent can be further clearly understood through the following specific embodiments given, but they do not limit the present patent.

[0021] Embodiment 1: An interface conversion circuit board, comprising: a plate shell 1, a plate body 4 disposed inside the plate shell 1, and a plate cover 2 for closing the plate shell 1.

One end of the conversion interface 3 having a jack 301 is located outside the plate shell 1, and the other end can be embedded inside the plate shell 1 and is located below the plate body 4;

[0022] Fix the conversion interface in the installation holes on both sides of the plate shell through a flange, and then install the plate body inside the plate shell, so that the elastic arc electrode in the first card slot at the bottom of the plate body contacts the bonding electrode at the top of the conversion interface, thereby making the conversion interface conduct electricity with the plate body;

[0023] A plurality of bonding electrodes 10 are provided on one side of the conversion interface 3 relative to the plate body 4. A plurality of first card slots 9 are provided at the bottom of the plate body 4, and an elastic arc electrode 5 for electrically connecting with the bonding electrodes 10 is arranged inside the first card slot 9;

During this process, the elastic arc electrode and the bonding electrode are automatically disconnected. Subsequently, insert a new conversion interface into the installation hole. During this process, the elastic arc electrode contacts the bonding electrode, and then fix the flange and the plate shell through screws.

[0025] One end of the above-mentioned elastic arc electrode 5 is fixedly connected to the inner wall of the first card slot 9, and the other end is movably connected to the first card slot 9.

The connecting portion 6 is fixedly connected to the inner wall of the first card slot 9. The movable portion 8 can slide along the first card slot 9. By contacting the bonding electrode through the arc portion, under the extrusion of the bonding electrode, the movable portion can move along the first card slot, so that the elastic arc-shaped electrode elongates to buffer the extrusion force. When the conversion interface is pulled out, under the action of the elastic restoring force, the elastic arc-shaped electrode can contract, which is beneficial to buffering the extrusion between the elastic arc-shaped electrode and the bonding electrode, and can also maintain the stability of the electrical connection between the elastic arc-shaped electrode and the bonding electrode during long-term use.

[0032] One end of the above-mentioned elastic arc-shaped electrode 5 is fixedly connected to the inner wall of the first card slot 9, and the other end is movably connected to the first card slot 9.

[0033] The above-mentioned elastic arc-shaped electrode 5 includes: a connecting portion 6, an arc portion 7, and a movable portion 8. The arc portion 7 located between the connecting portion 6 and the movable portion 8 can contact the bonding electrode 10. The connecting portion 6 is fixedly connected to the inner wall of the first card slot 9. The movable portion 8 can slide along the first card slot 9.

[0034] A flange 11 is fixedly installed on the outer side of the above-mentioned plate housing 1 and on the circumferential outer wall of the above-mentioned conversion interface 3.

[0038] When the conversion interface needs to be replaced, only need to remove the screws connecting the flange, then the conversion interface can be pulled out. During this process, the elastic arc electrodes and the bonding electrodes are automatically disconnected. Subsequently, insert the new conversion interface into the installation hole. During this process, the elastic arc electrodes and the bonding electrodes are in contact, and then fix the flange and the plate housing with screws.

[0039] When adopting the above interface conversion circuit board, by inserting the conversion interface into the installation hole, the bonding electrodes of the conversion interface are electrically connected to the elastic arc electrodes on the plate body, so that the rapid connection between the conversion interface and the plate body can be realized, and the conversion interface can also be pulled out of the installation hole, which can realize the rapid disassembly and installation of the conversion interface, facilitate the replacement of the conversion interface, and improve the overall use efficiency.
