The battery interface of the device to be tested includes pins, which are usually an SCL pin and an SDA pin.
In this embodiment, the connection tool 100 may be fixed in a battery compartment of the device under test. Under the condition that the connection tool 100 is fixed in the battery compartment of the device to be tested, the fourth pad group 160 is connected to the second testing end of the device to be tested, and the pads in the third pad group 150 are in one-to-one correspondence communication with the pads in the fourth pad group 160. Thus, the third pad group 150, the fourth pad group 160, and the second test terminal of the device under test form a path. Under the condition that the test tool is connected with the third pad group 150 of the device to be tested, the test tool can read the test result of the device to be tested through the second test end of the device to be tested.

In an embodiment, as shown in fig. 3, the connection tool 100 provided in the embodiment of the present application further includes an electric quantity detection device 170 and/or an external power detection device 180, where:
the power detection device 170 is used for detecting the power of the battery.
The external power detection device 180 is used to detect whether the test fixture is powered on the connection fixture 100.
In the present embodiment, the power detection device 170 is connected to the positive electrode of the battery 110 to detect the power of the battery.
In this embodiment, since the communication interface generally includes a power supply pin, when the first pad group 120 includes a pad corresponding to the pin included in the communication interface of the device under test, the first pad group 120 generally includes a pad corresponding to the power supply pin.
In this embodiment, when the test tool is connected to the first pad group 120, the test tool may supply power to a pad corresponding to a power supply pin in the first pad group 120, and the pad corresponding to the power supply pin in the first pad group 120 is connected to the charging terminal of the battery 110. On this basis, the external power detection device 180 is connected to the charging terminal of the battery 110 to detect whether the test tool is energized to the connection tool 100.
Further, when the test fixture is connected to the first pad 120, the external power detection device 180 detects whether the test fixture is powered on the connection fixture 100, so that whether the test fixture fails can be laterally reflected. Specifically, when the test tool is connected to the first pad group 120, if the external power detection device 180 detects that the test tool is not powered on the connection tool 100, it indicates that the test tool has a fault.
On the basis of the above embodiment, as shown in fig. 3, the electric quantity detection device 170 includes an electric quantity meter 171, a first detection unit 172, and a first indicator light 173, wherein:
an input terminal of the fuel gauge 171 is connected to the positive electrode of the battery 110, and an output terminal of the fuel gauge 171 is connected to an input terminal of the first detection unit 172.
The output end of the first detection unit 172 is connected to the first indicator lamp 173, and the first detection unit 172 controls the brightness of the first indicator lamp 173 according to the output result of the fuel gauge 171.
In the present embodiment, the electricity meter 171 detects the amount of electricity of the battery 110, and sends the output result to the first detection unit 172. The first detection unit 172 controls the brightness of the first indicator lamp 173 according to the output result. Specifically, when the output result indicates that the amount of charge of the battery 110 is sufficient, the first indicator 173 is controlled to be bright. In the case where the output result indicates that the amount of charge of the battery 110 is insufficient, the first indicator 173 is controlled to be dimmed.
In this embodiment, the power of the battery 110 can be visually checked according to the brightness of the first indicator 173. Therefore, when the battery 110 is short of power, the tester is prompted to replace the battery in time.
In the above embodiment, the power detection device 170 further includes a first switch 174. The first switch 174 is connected between the first detection unit 172 and the first indicator lamp 173.

In this embodiment, since the first indicator 173 may affect the test result of the device under test in the lit state, the first switch 174 may be arranged to cut off the path between the first indicator 173 and the first detection unit 172, so as to avoid the effect on the test result of the device under test.
In one embodiment, the external power detection device 180 includes a second detection unit 181 and a second indication lamp 182, wherein:
an input terminal of the second sensing unit 181 is connected to a charging terminal of the battery 110, and an output terminal of the second sensing unit 181 is connected to the second indicator lamp 182.
The second test unit 181 is used to detect whether an electrical signal is present at the charging terminal of the battery 110, and in the case where an electrical signal is present, to control the second indicator lamp 182 to be turned on, and in the case where an electrical signal is not present, to control the second indicator lamp 182 to be turned off.
In the present embodiment, when the test tool is connected to the first pad 120, the second detection unit 181 detects whether an electrical signal is present at the charging terminal of the battery 110, that is, whether the test tool supplies power to the connection tool 100. The second detection unit 181 controls the second indicator lamp 182 to be turned on or off according to the detection result. Specifically, when the detection result indicates that no electric signal exists at the charging end, it is determined that the test tool does not energize the connection tool 100, and at this time, the second indicator lamp 182 is controlled to be turned off. Correspondingly, when the detection result shows that the electric signal exists at the charging end, the test tool is determined to be powered on the connection tool 100, and at the moment, the second indicator lamp 182 is controlled to be turned on.
In this embodiment, when the test fixture is connected to the first pad 120, whether the test fixture supplies power to the connection fixture 100 can be visually checked according to the on/off of the second indicator lamp 182.
On the basis of the above embodiment, the external power detection device 180 further includes the second switch 183.
Wherein:
the second switch 183 is connected between the second detection unit 181 and the second indicator lamp 182.
In this embodiment, the second switch 183 is usually a physical switch, and the second switch 183 is disposed on an outer surface of the connection tool 100, so that the tester can control the second switch 183 to be in an on state or an off state.
In this embodiment, since the second indicator light 182 may affect the test result of the device under test in a lighting state, the second switch 182 may be arranged to interrupt the path between the second indicator light 182 and the second detection unit to avoid affecting the test result of the device under test.
In one embodiment of the present application, the connection tool 100 further includes a logo structure. When the connection tool 100 is fixed in the battery compartment of the device under test, the identification structure is exposed to the outside.

In one embodiment of the present application, the connection tool 100 further includes a handle. The handle is exposed to the outside when the connection tool 100 is fixed in the battery compartment of the device under test.
In this embodiment, by arranging the handle on the connection tool 100, the tester can fix the connection tool 100 in the device to be tested conveniently, and the risk that the connection tool 100 slides down is reduced.

Thus, it is not necessary to set a corresponding set of needles or pads on the test fixture to communicate with the first pad set 120. This increases the compatibility of the connection tool 100 with the test tool.
