As shown in fig. 1 and 2, the preferred embodiment discloses a connection wire 100 for inspecting products for inspecting product performance and controlling quality of inspected products before shipment. The connecting wire 100 comprises a wire main body 110, a first connecting end 120 and a second connecting end 130, wherein the first connecting end 120 and the second connecting end 130 are separately positioned at two ends of the wire main body 110, electric contact pins are arranged in the first connecting end 120 and the second connecting end 130, one end of the first connecting end 120 and one end of the second connecting end 130 are suitable for being connected with an external product to be detected, and the other end of the first connecting end 120 and the other end of the second connecting end 130 are suitable for being connected with external detection equipment. In this embodiment, the statistical circuit 150 and the third connection end 160 are led out from the first connection end 120 (or the wire main body 110 or the second connection end 130) through the conducting wire 140, and a protective shell 170 is disposed outside the statistical circuit 150, wherein the third connection end 160 is disposed at one end of the conducting wire 140, and the statistical circuit 150 is connected in the conducting wire 140. The electric contact pin adopts a gold-plated contact to reduce contact resistance and ensure the electrified stability after contact. In this embodiment, the detected product is a display card or a motherboard, and the connection line 100 is an HDMI interface connection line. The first connection end 120 is used for plugging and connecting the tested product to realize electrical connection with the tested product, and the second connection end 130 is used for plugging and connecting the testing equipment.

As shown in fig. 3 and 4, the counting circuit 150 includes a microprocessor 151, a memory 152, and a counting unit 153, where the counting unit 153 is used for counting the number of times of power-on of the first connection terminal 120 and the second connection terminal 130. Specifically, one end of each electrical contact pin is electrically connected to a wire, and after the electrical contact pins in the first connection end 120 or/and the second connection end 130 are electrically connected to the corresponding components, a current loop is formed between the electrical contact pins and the third connection end 160, and at this time, the counting unit 153 only needs to count the number of times of completing the current loop with the first connection end 120 and the second connection end 130 after each plugging connection, so as to obtain the number of times of power on. The memory 152 is used for storing the power-on times, and the third connection terminal 160 is adapted to be electrically connected to an external controller so that the external controller can acquire the data in the memory 152.

For example: after the third connection end 160 is electrically connected to the external controller, each time the first connection end 120 is connected to the product to be tested, a current loop is formed between the third connection end 160 and the first connection end 120; until the first connection terminal 120 is separated from the product to be detected, the current loop is cut off, and the on-off of the current loop is completed once, at this time, the counting unit 153 increases the one-time energization count at the first connection terminal 120. Similarly, after the third connection end 160 is electrically connected to the external controller, the second connection end 130 is plugged with the detection device, so that a current loop is formed between the third connection end 160 and the second connection end 130; until the second connection 130 is separated from the detecting device, the current loop is cut off, and the on-off of the current loop is completed once, at which time the counting unit 153 increases the one-time energization count at the second connection 130.

In this embodiment, the statistics circuit 150 further includes a display unit 156 and an identity unit 157, where the display unit 156 is configured to display the counted number of times of power-on of the first connection terminal 120 and the second connection terminal 130. The identity unit 157 is used to identify the unique identity of the connection line 100 to facilitate the tracing and tracking of the connection line 100. The identity unit 157 may be identification data stored in the memory 152, and after the third connection terminal 160 is connected to an external controller, the external controller can obtain the identification data to determine whether the number of times of power-on of the first connection terminal 120 and the second connection terminal 130 in the connection line 100 reaches the set number of times of power-on.

Because the control circuit 150 is disposed in the connection wire 100, the control circuit 150 includes the counting unit 153, the alarm unit 154, the display unit 156 and the power-off unit 155, the counting unit 153 can count the power-on times of the first connection end 120 and the second connection end 130, so that the connection wire is safer, when the first connection end 120 and the second connection end 130 are the same universal interface, the subsequent problem caused by the exchange of the connection ends in the connection wire is not worry, and the user can know the service life of the connection wire by connecting the third connection end 160 with an external controller. In addition, after the counted number of times reaches the set number of times, the alarm unit 154 can give an alarm, and the power-off unit 155 cuts off the power output of the connecting wire 100, so that the connecting wire 100 is more suitable for product monitoring.

It should be noted that the functions of the counting unit 153, the alarm unit 154, the display unit 156 and the power-off unit 155 in this embodiment may be implemented by conventional circuits and general electronic components in the prior art.
