[0031] A control panel connected with an external power supply is arranged in the containing cavity, the control panel is connected with a detection assembly 6 for detecting whether the solar panel has electricity, and the detection assembly 6 has a metal terminal 606 connected with the solar panel; the inner side wall of the light-transmitting hole is inwardly convexly provided with a bottom airbag layer 202, the bottom airbag layer 202 is annular and arranged along the inner side wall of the light-transmitting hole;

[0032] When the solar panel is placed in the light-transmitting hole of the placing plate 2, the light-absorbing surface of the solar panel is arranged opposite to the light-transmitting hole, and the bottom of the outer periphery of the solar panel abuts on the bottom air bag layer 202 from top to bottom.

[0033] The low-leakage high-precision solar panel testing jig provided above covers the light-transmitting opening on the jig table 1 with the placing plate 2 to avoid light leakage of the lamp plate 4, and different sizes of light-transmitting holes of the placing plate 2 can be replaced at any time, increasing the practicability of the placing plate 2. When the solar panel is placed in the light-transmitting hole of the placing plate, the accuracy of solar panel irradiation can be improved. The bottom air bag layer 202 arranged on the light-transmitting hole is used to close the placed solar panel, avoiding light leakage from the gap, so that the operator will not cause eye redness, blurred vision and other discomfort symptoms, and will not cause damage to the retina and permanent vision loss. The detection assembly 6 can effectively improve the work efficiency.

[0034] The bottom of the inner side wall of the light-transmitting opening extends inward to form an abutting section, and the abutting section is arranged along the circumference of the inner side wall of the light-transmitting opening.

When the placing plate 2 is embedded in the light-transmitting opening, the protruding strip 201 is inserted into the groove, and the placing plate 2 is closed and abuts with the abutting section.

[0035] In this embodiment, the abutting section of the light-transmitting opening is used to place the placing plate 2, and the placing plate 2 is inserted into the groove by the protruding strip 201, so that the light emitted by the lamp plate 4 cannot irradiate the operator.

[0036] The top end of the placing plate 2 is upwardly protruding and provided with a lifting ring for lifting the placing plate 2 out of the light-transmitting opening by pulling. In this way, the placing plate 2 can be quickly extracted.

[0037] The outer periphery of the bottom air bag layer 202 extends to the inner side wall of the light-transmitting hole to form an outer periphery air bag layer 203 covering the inner side wall of the light-transmitting hole. When the solar panel is placed in the light-transmitting hole of the placing plate 2, the outer periphery of the solar panel abuts on the outer periphery air bag layer 203.

[0038] In this embodiment, the outer periphery air bag layer 203 can form a protection for the outer periphery of the solar panel, and can also close the gap between the solar panel and the outer periphery air bag layer 203, reducing light leakage of the light emitted by the lamp plate 4.

[0040] When the bottom air bag layer 202 is not pressed, the bottom air bag layer is in a full arrangement, and the outer peripheral air bag layer 203 and the balloon 204 are in a partially relaxed arrangement; when the bottom of the solar panel is pressed on the bottom air bag layer 202, the flowing liquid in the bottom air bag layer 202 is extruded to enter the outer peripheral air bag layer 203 through the plurality of through holes, the outer peripheral air bag layer 203 is extruded and expanded, the outer peripheral air bag layer 203 seals the gap between the solar panel and the outer peripheral air bag layer 203, and the flowing liquid in the outer peripheral air bag layer 203 is reversely flowed into the bottom air bag layer by extruding the balloon 204.

[0041] In the embodiment, when the outer periphery of the solar panel is also pressed on the outer peripheral air bag layer 203, the liquid is extruded to enter the balloon 204 through the plurality of through holes, so that the balloon 204 is expanded to form a spherical shape, and the liquid is reversely flowed into the bottom air bag layer 202 by extruding the liquid in the balloon 204 to pop the solar panel out of the light transmission hole.

[0042] The lamp plate 4 is located directly below the placing plate 2, and the lamp plate 4 is provided with a light guide cover 5 surrounding a cover cavity in a frustum shape. The lamp plate 4 is arranged at the bottom of the cover cavity, and the volume of the cover cavity gradually decreases in a top-down direction. The bottom of the light guide cover 5 surrounds the outer periphery of the lamp plate 4, the top of the light guide cover 5 has a top opening communicating with the cover cavity, the top of the light guide cover 5 abuts against the bottom of the placing plate 2, and the light transmission hole is arranged in alignment with the top opening of the cover cavity in an up-down direction.

[0043] In the embodiment, the light guide cover 5 can limit the light emitted by the lamp plate 4 from leaking through the gap between the jig table 1 and the base 3.

[0044] The inner wall surface of the light guide cover 5 is in a spherical shape, forming a smooth spherical surface, and the spherical surface is covered with a reflective film, so that the light emitted by the lamp plate 4 can be reflected, increasing the light emitted by the lamp plate 4 to the solar panel and improving the speed of the solar panel absorbing light energy, which also shortens the waiting time of the operator.

[0045] The detection assembly 6 includes a wire, one end of the wire is connected with a control board, and the other end of the wire is connected with a probe head 601. The probe head 601 is internally provided with an externally open mounting cavity, and the mounting cavity is internally provided with a soft push strip 603 sliding up and down. The externally open mounting cavity is protrudingly provided with a push-pull switch 602 sliding up and down, the bottom end of the push-pull switch 602 abuts against the push strip 603, the upper end of the mounting cavity is in open communication with the lower end of an over cavity, and the over cavity has two clamping wire strips 604 sliding transversely, along the direction of communication from the mounting cavity to the over cavity.

[0046] The push strip 603 extends into two extension sections which are separated by the fixing column and connected to one end of the two clamping strips 604 and arranged in a bent shape with the clamping strips 604. The top end of the probe head 601 is provided with a sealing strip 605, and the inside of the probe head 601 is provided with a plurality of metal terminals 606. The upper end of the metal terminal 606 extends outwardly through the clamping strip 604 and the sealing strip 605, and the lower end of the metal terminal 606 is connected to the wire through the probe head 601.

[0047] In the embodiment, the push strip 603 is controlled by the push-pull switch 602 to push upward, so that the two extension sections push the two clamping strips 604 to move to the two sides of the excess cavity, thereby driving the metal terminals 606 to connect the terminals on the solar panel. Since the distance between the terminals on each solar panel is different, this design structure can improve the work efficiency of the operator and does not need to replace different sizes of metal terminals 606 for detection.

[0048] The guide column is arranged in the excess cavity and located at the bent position, so that the push strip 603 can move the extension section without deviation or jamming.

[0049] The sealing strip 605 has a limiting opening arranged towards the metal terminal 606, so that the upper end of the metal terminal 606 can be limited to displace in the same horizontal plane.

[0050] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
