[0024] The specific implementation of the utility model is further described below through specific embodiments and in conjunction with the accompanying drawings.

[0025] Embodiment one:

[0026] A split cable connector device capable of achieving electrical load balancing, such as Figure 1 As shown, the cable connector device mainly consists of a male connector 1, a female connector 2 and a connecting ring 3. When in use, one side of the male connector 1 is connected to the first group of cables, the female connector 2 is connected to the second group of cables, and then the male connector 1 is connected to the female connector 2 to achieve the connection between the two groups of cables.

[0027] like Figure 2 As shown, the male head 1 and the female head 2 are both tubular in shape as a whole, and a partition wall is used in the middle to separate the space inside the tube into two left and right chambers. The size of the chamber opposite to the male head 1 and the female head 2 is smaller than the size of the other chamber, and the sizes of the chambers separated by the male head 1 and the female head 2 are the same.

[0028] like Figure 3 As shown, the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral-line cable connector 104 are arranged on the partition wall on the side of the larger chamber of the male connector 1. When arranged, the first A-line cable connector 101, the first B-line cable connector 102, and the first C-line cable connector 103 are located on the same circumference, and each cable connector is spaced 120 degrees apart from the adjacent cable connectors to achieve maximum electrical isolation and avoid mutual interference between cable connectors. The neutral-line cable connector is arranged at the center of the circle. The shapes of the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral-line cable connector 104 are all arranged to be conical, and a screw is arranged on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. After the A cable, B cable, and C cable are inserted into the first A cable connector 101, the first B cable connector 102, and the first C cable connector 103, respectively, they are tightened with screws to achieve electrical connection between the cable connectors and the cables. The first A cable connector 101, the first B cable connector 102, the first C cable connector 103, and the first neutral cable connector 104 are of equal length, and their lengths are shorter than the height of the side wall of the chamber, that is, the first A cable connector 101, the first B cable connector 102, the first C cable connector 103, and the first neutral cable connector 104 are completely within the chamber. Therefore, when the male connector 1 is connected to the cable group, part of the side wall will fit the cable group to improve the sealing.

[0029] like Figure 4As shown, the smaller chamber of the male head 1 is provided with an A-line connector 108, a B-line connector 109, a C-line connector 110, and a neutral line connector 111, which are used for electrical connection with the female head 2. The shapes of the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are all set to be conical, and a screw is configured on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. When the A electrical pin, the B electrical pin, and the C electrical pin are respectively inserted into the A cable, the B cable, and the C cable, they are tightened with screws respectively, thereby achieving electrical connection between the male head 1 and the female head 2. It should be particularly noted that the materials such as the outer shells of the male head 1 and the female head 2 need to be insulating materials, and the cable connectors and connectors in the male head 1 and the female head 2 are metal materials (such as copper). In addition, the connecting ring 3 is also made of insulating materials. The A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are of equal length, and their length is longer than the height of the side wall of the chamber, that is, the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are partially located outside the chamber. Therefore, there is a gap at the connection between the male connector 1 and the female connector 2, and the connecting ring 3 is required to be sealed to achieve electrical isolation from the outside. Four openings are provided on the isolation wall of the male connector 1, through which the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104 are respectively connected to the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111.

[0030] like Figure 5 As shown, the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 are arranged in the larger chamber of the female connector 2. Like the male connector 1, the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 are conical in shape, and a screw is arranged on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. At the same time, the lengths of the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 are the same as those of the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104.

[0031] like Figure 6 As shown, the smaller chamber of the female connector 2 is provided with an A-line pin 205, a B-line pin 206, a C-line pin 207, and a neutral line pin 208, and the pins are in a standard cylindrical shape. The length of the pins matches the depth of the holes in the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111.

[0032] like Figure 7 As shown, the present invention can be used for the relay connection of two cables, and can also be used for the connection of electrical loads and power supply cables. When the cable connection needs to be replaced, the male head 1 and the female head 2 are disconnected, and then rotated 120 degrees or 240 degrees to switch the cable that has been circulating a small current for a long time to a load that circulates a large current. Since the disconnection of the male head 1 and the female head 2 of the present invention is realized manually, it is necessary to check whether the current of the three cables is zero before disconnection. If the current of any cable line is not zero, the male head 1 and the female head 2 cannot be disconnected at this time, and an arc will be generated during disconnection, causing personal injury. When the current of all cable lines is zero, the male head 1 and the female head 2 can be safely disconnected at this time, and the electrical connection relationship between the front and rear cables can be converted to achieve load balancing.

[0033] This embodiment arranges multiple cable connectors on the same circumference, adjusts the connection angle between the male head 1 and the female head 2, adjusts the connection relationship between the cables, and adjusts the loads of different cables, so that the aging degree of all cables is roughly the same, thereby improving the overall service life of the cable group and reducing safety hazards.

[0034] Embodiment 2:

[0035] The device structure of this embodiment is as follows Figure 1 As shown, the cable connector device mainly consists of a male connector 1, a female connector 2 and a connecting ring 3. When in use, one side of the male connector 1 is connected to the first group of cables, the female connector 2 is connected to the second group of cables, and then the male connector 1 is connected to the female connector 2 to achieve the connection between the two groups of cables.

[0036] like Figure 2 As shown, the male head 1 and the female head 2 are both tubular in shape as a whole, and a partition wall is used in the middle to separate the space inside the tube into two left and right chambers. The size of the chamber opposite to the male head 1 and the female head 2 is smaller than the size of the other chamber, and the sizes of the chambers separated by the male head 1 and the female head 2 are the same.

[0037] like Figure 3As shown, the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral-line cable connector 104 are arranged on the partition wall on the side of the larger chamber of the male connector 1. When arranged, the first A-line cable connector 101, the first B-line cable connector 102, and the first C-line cable connector 103 are located on the same circumference, and each cable connector is spaced 120 degrees apart from the adjacent cable connectors to achieve maximum electrical isolation and avoid mutual interference between cable connectors. The neutral-line cable connector is arranged at the center of the circle. The shapes of the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral-line cable connector 104 are all arranged to be conical, and a screw is arranged on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. A transformer outlet hole 112 is provided on the side of the male connector 1, and the secondary signal line of the current transformer extends to the outside of the male connector 1 through the transformer outlet hole 112 for measurement. After the A cable, B cable, and C cable are respectively inserted into the first A-line cable connector 101, the first B-line cable connector 102, and the first C-line cable connector 103, they are tightened with screws, which not only tightens the electrical connection between the cable connector and the cable, but also fixes the current transformer. The first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104 are of equal length, and the length is shorter than the height of the side wall of the chamber, that is, the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104 are completely located within the chamber. Therefore, when the male connector 1 is connected to the cable group, part of the side wall will fit the cable group to improve the sealing performance. An A-line current transformer 105 , a B-line current transformer 106 , and a C-line current transformer 107 are respectively disposed on the bottom of the outer surfaces of the first A-line cable connector 101 , the first B-line cable connector 102 , and the first C-line cable connector 103 .

[0038] like Figure 4As shown, the smaller chamber of the male head 1 is provided with an A-line connector 108, a B-line connector 109, a C-line connector 110, and a neutral line connector 111, which are used for electrical connection with the female head 2. The shapes of the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are all set to be conical, and a screw is configured on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. When the A electrical pin, the B electrical pin, and the C electrical pin are respectively inserted into the A cable, the B cable, and the C cable, they are tightened with screws respectively, thereby achieving electrical connection between the male head 1 and the female head 2. It should be particularly noted that the materials such as the outer shells of the male head 1 and the female head 2 need to be insulating materials, and the cable connectors and connectors in the male head 1 and the female head 2 are metal materials (such as copper). In addition, the connecting ring 3 is also made of insulating materials. The A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are of equal length, and their length is longer than the height of the side wall of the chamber, that is, the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111 are partially located outside the chamber. Therefore, there is a gap at the connection between the male connector 1 and the female connector 2, and the connecting ring 3 is required to be sealed to achieve electrical isolation from the outside. Four openings are provided on the isolation wall of the male connector 1, through which the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104 are respectively connected to the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111.

[0039] like Figure 5 As shown, the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 are arranged in the larger chamber of the female connector 2. Like the male connector 1, the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 are conical in shape, and a screw is arranged on the outer surface of each cable connector, and the inner hole of the screw is also designed in a conical shape to facilitate better tightening of the screw. At the same time, the length of the second A-line cable connector 201, the second B-line cable connector 202, the second C-line cable connector 203, and the second neutral line cable connector 204 is the same as that of the first A-line cable connector 101, the first B-line cable connector 102, the first C-line cable connector 103, and the first neutral line cable connector 104. The bottom of the cable connector of the female connector 2 does not need to be equipped with a current transformer.

[0040] like Figure 6As shown, the smaller chamber of the female connector 2 is provided with an A-line pin 205, a B-line pin 206, a C-line pin 207, and a neutral line pin 208, and the pins are in a standard cylindrical shape. The length of the pins matches the depth of the holes in the A-line connector 108, the B-line connector 109, the C-line connector 110, and the neutral line connector 111.

[0041] like Figure 7 As shown, the present invention can be used for the relay connection of two cables, and can also be used for the connection between an electrical load and a power supply cable. The three current transformers in the male connector 1 can monitor the working current of the A line, the B line, and the C line. When the current values ​​in the three lines ABC are not equal for a long time, the current transformers can be used to monitor the working current of the A line, the B line, and the C line. Figure 4 As shown, the male connector 1 and the female connector 2 are disconnected, and then rotated 120 degrees or 240 degrees to switch the cable line that has been circulating a small current for a long time to a load that circulates a large current. It should be noted that since the disconnection of the male connector 1 and the female connector 2 of the present invention is achieved manually, it is necessary to check whether the output signals of the three current transformers are zero before disconnection. If the output of any current transformer is not zero, the male connector 1 and the female connector 2 cannot be disconnected at this time, and an arc will be generated during disconnection, causing personal injury. When all current transformers output zero, the male connector 1 and the female connector 2 can be safely disconnected at this time, and the electrical connection relationship between the front and rear cables can be converted to achieve load balancing.

[0042] This embodiment sets a current transformer on each male cable connector to detect the current of each cable line in real time and understand the load of the cable line, thereby providing data support for dynamically adjusting the connection relationship between the cables.

[0043] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
