The function of the supporting legs 2 is to cooperate with the burning test bench to set and support the burning carrier on the burning test bench.

[0042] The top of the box is open, that is, the top plate is designed to be a detachable structure. The part of the bottom plate outside the box 1 is provided with a plurality of spring probes 3, which penetrate the bottom plate of the box and extend to the inside of the bottom plate; the spring probes 3 are used to be electrically connected to the burning test bench, access the test bench electrical signal, serve as the input of the external power supply of the entire burning carrier, and access the burning signal. The support foot 2 can be designed to be sleeve-shaped and also has a positioning function. A corresponding positioning foot can be designed on the test bench, and the support foot is sleeved on the positioning foot of the test bench to ensure that each time the carrier is automatically grasped by the clamp to the workstation, the position of the carrier is the same each time, thereby ensuring that the carrier spring probe 3 is in good contact with the mother pin on the workstation, and the signal transmission and power supply are stable; the soldering position is consistent, and the soldering effect is stable. At the same time, the size of the opening on the bottom plate 101 matches the outer diameter of the spring probe 3 to prevent the spring probe 3 from being subjected to radial force, which can extend the service life of the spring probe 3.

[0043] The interior of the box 1 is used as a storage space for the PCBA board connection wires and the internal PCBA board card to prevent the wires from being damaged during use. An internal PCBA board slot connector 4 is provided inside the box, and an internal PCBA board is installed in the internal PCBA board slot connector 4; the spring probe 3 is electrically connected to the internal PCBA board slot connector 4 to achieve electrical signal transmission between the internal PCBA board and the burning test bench. The side panel of the box is provided with a plurality of adapters 5, and the adapters 5 are electrically connected to the internal PCBA board slot connector 4 to achieve signal transmission between the external signal and the internal PCBA board. The adapter 5 can be selected to be arranged on one side or multiple sides of the box. The burner adapter uses a standard adapter on the market to reduce the types of materials.
