Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-3 , an automatic wire alignment device for an overload connector, comprising a trolley connector plug, a breaker connector socket, a network cable, a signal transmitting device and a signal receiving device;

[0026] There are two groups of network cables. One end of one group of network cables is crimped on the trolley connector plug, and one end of the other group of network cables is crimped on the breaker connector socket;

[0027] The other ends of the two network cables are crimped with RJ45 connectors in the same color sequence;

[0028] The signal transmitting device is connected to the trolley connector plug through an RJ45 connector;

[0029] The signal receiving device is connected to the breaker connector socket of the corresponding trolley connector plug through an RJ45 connector;

[0030] The signal transmitting device sends a signal through the network cable. The signal receiving device receives the signal sent by the signal transmitting device and feeds back the received information from the signal receiving device.

[0031] Through the above technical solution, two groups of network cables are used to connect the trolley connector plug and the breaker connector socket at the corresponding position respectively, and RJ45 connectors are crimped on the other ends of the network cables. Then, the RJ45 connectors are respectively plugged into the signal transmitting device and the signal receiving device. The signal receiving device receives the signal transmitted by the signal transmitting device. According to the signal indication of the signal transmitting device and the signal receiving device, it is judged whether there is misconnection or omission in the control circuit of the cable, achieving the effect of improving the accuracy and convenience of detection.

[0032] Specifically, the network cable is an 8-core network cable, and the number of each group of network cables is multiple. The cores of the multiple network cables are adapted to the number of cores of the trolley connector plug.

[0033] Through the above technical solution, the network cable is set as a conventional 8-core network cable, which is convenient for procurement and can be matched with the cores of the trolley connector plug or the breaker connector socket in large quantities, reducing the usage amount of the network cable. When connecting the network cable, corresponding serial numbers are pasted in pairs on the outer surface of the network cable for convenient detection and to avoid taking the wrong network cable.

[0034] Specifically, the network cable is a Cat6 or Cat6A network cable, and the length of the network cable does not exceed 50 meters.

[0035] Through the above technical solution, the purpose of using a Cat6 or Cat6A network cable is to improve the quality of detection signal transmission. The purpose of setting the length of the network cable is to avoid attenuation of the detection signal due to long-distance transmission, thus affecting the detection accuracy.

[0036] Specifically, the network cable is pressed into the RJ45 connector in the wire sequence of 258A or 258B.

[0037] Through the above technical solution, connecting the RJ45 connector using the standard communication network cable wiring method can achieve the effect of easy memorization, eliminating the need to re-memorize the wire sequence corresponding to all RJ45 connectors, and improving work efficiency.

[0038] Specifically, the signal transmitting device and the signal receiving device are used in pairs, and their signal segments are the same.

[0039] Through the above technical solution, using the signal transmitting device and the signal receiving device in pairs can increase the accuracy of detecting signal transmission and reception, avoiding errors in detection results caused by equipment mismatch. The working principles of the signal transmitting device and the signal receiving device are the same as those of the existing network cable tester, and detection is achieved by comparing continuity and wire sequence.

[0040] Specifically, a signal indicator light is provided on the signal transmitting device, and a signal receiving indicator light is provided on the signal receiving device.

[0041] Through the above technical solution, corresponding indicator lights are provided on both the signal transmitting device and the signal receiving device, enabling the detection of misconnection or missed connection problems by comparing the flashing of the indicator lights on the signal transmitting device and the signal receiving device.

[0042] Specifically, a wiring terminal is provided on the side of the network cable away from the RJ45 connector, and the wiring terminal is adapted to the wiring points of the trolley connector plug and the circuit breaker connector socket.

[0043] Through the above technical solution, by using the wiring terminal to connect to the end of the network cable away from the RJ45 connector, it can be more quickly connected to the trolley connector plug and the circuit breaker connector socket, eliminating the need to split and connect the network cable cores each time.

[0044] The specific operation is as follows:

[0045] 1. Prepare one trolley connector plug and one circuit breaker connector socket each.

[0046] 2. Press one end of the 8-core network cable in sequence onto the prepared trolley connector plug. When one network cable core is used up, a new network cable can be added until all the sockets for which the secondary wires need to be verified are wired, and then press a RJ45 connector onto each network cable.

[0047] 3. Press the network cable onto the circuit breaker socket in the same wire color as the wiring of the corresponding trolley connector plug and press a RJ45 connector onto it.

[0048] 4. The network cable connected to the plug of the trolley connector through the signal transmitting device, and the receiving device accesses the corresponding socket-end network cable. The signal transmitting device sends the signal to the receiving device one by one for each cable. After receiving the signal, the receiving device will display the received signal status. After one network cable is detected, switch to the next group of corresponding network cable interfaces. During this process, if there are any wrong connections or missed connections in the control circuit of the cable, they can be detected through the receiving device.

[0049] 5. After one device is detected, the plug and socket of the detection device can be removed and inserted into the connector of the next circuit breaker trolley to detect the next device.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
