[0021] In one embodiment, such as Figures 1-5As shown, a circuit testing device includes: a cable connector holder 1; a first connecting wire 2 is provided on one end face of the cable connector holder 1; a rear pin 3 is provided on the other end face of the first connecting wire 2; a second connecting wire 4 is provided on the other end face of the cable connector holder 1; a front pin 5 is provided on the other end face of the second connecting wire 4; a third connecting wire 6 is provided on the left end face of the cable connector holder 1; a manual probe 7 is provided on the other end face of the third connecting wire 6; a power cord 8 is provided on the right end face of the cable connector holder 1; a power plug 9 is provided on the other end face of the power cord 8; and multiple sets of interfaces 10 are provided on the upper end face of the cable connector holder 1.
[0022] Specifically, during testing, align the connectors of the rear terminals with the interfaces 10 on the cable connector holder 1, and align the connectors of the front terminals with the interfaces 10 on the cable connector holder 1. Connect the power plug 9 to the external power source. Insert the rear pins 3 into the corresponding wiring holes of the rear terminals and observe whether all indicator lights are fully lit. Similarly, insert the front pins 5 into the corresponding wiring holes of the front terminals and observe whether all indicator lights are fully lit. If all indicator lights are lit, the circuit is powered on and the wiring is correct. This method can solve the problems of slow testing efficiency and easy omissions, thus enabling convenient and quick testing of whether the circuit is connected and improving the efficiency of circuit testing.
[0023] like Figures 2-4 As shown, a protective cover 11 is provided on the upper surface of the cable connector fixing bracket 1. Two sets of fixing blocks 12 are provided on each of the two side walls of the protective cover 11. Each of the fixing blocks 12 has a set of connecting blocks 13. Each of the connecting blocks 13 has a set of threaded screws 14. One end of each screw 14 has a rotating block 15. The other end of each screw 14 has a clamping block 16, which is respectively provided on the two side walls of the cable connector fixing bracket 1. One side surface of each clamping block 16 has a set of anti-slip pads 17. The protective cover... A protective pad is provided on the inner wall of the cable connector holder 11. When the cable connector holder 1 is not in use, the protective cover 11 can be placed on the end face of the cable connector holder 1. Then, the multiple sets of rotating blocks 15 are rotated. The multiple sets of rotating blocks 15 drive the multiple sets of clamping blocks 16 to move through the screw 14, so that the multiple sets of clamping blocks 16 press against the two side walls of the cable connector holder 1. This allows the protective cover 11 to protect the multiple sets of interfaces 10 on the upper end face of the cable connector holder 1, preventing dust from entering the interior of the multiple sets of interfaces 10. This is quite practical.
[0024] The above embodiment discloses a circuit testing device. During testing, the connectors of the rear terminals are connected to the interfaces 10 on the cable connector holder 1, and the connectors of the front terminals are connected to the interfaces 10 on the cable connector holder 1. The power plug 9 is connected to an external power source for power supply. The rear pins 3 are inserted into the corresponding wiring holes of the rear terminals, and the indicator lights are observed to be fully lit. The front pins 5 are inserted into the corresponding wiring holes of the front terminals, and the indicator lights are observed to be fully lit. If the indicator lights are fully lit, the circuit is powered on and the wiring is correct. When the cable connector holder 1 is not in use, the protective cover 11 can be placed on the end face of the cable connector holder 1. Then, multiple sets of rotating blocks 15 are rotated. The multiple sets of rotating blocks 15 drive multiple sets of clamping blocks 16 to move through the screw 14, so that the multiple sets of clamping blocks 16 press against the two side walls of the cable connector holder 1. This allows the protective cover 11 to protect the multiple interfaces 10 on the upper end face of the cable connector holder 1, preventing dust from entering the interior of the multiple interfaces 10. This is quite practical.
