In fig. 1, the number of through holes 11 is 4, and specifically, the number of through holes 11 can be adjusted according to actual requirements.
As shown in fig. 2, one end of the connecting terminal 2 is provided with a blind hole 21 for inserting the cable 3, and the axial direction of the blind hole 21 is the same as the axial direction of the through hole 11; the connecting terminal 2 perpendicular to the surface provided with the blind hole 21 is also provided with a plurality of second mounting holes 20 communicated with the blind hole 21, and the axial direction of the first mounting hole 10 is in the same direction as the axial direction of the second mounting hole 20; the number of the second mounting holes 20 in fig. 2 is 2, the dispersible cable 3 is pressed by the abutting portion 41, so that the force applied to the cable 3 by the abutting portion 41 is prevented from being concentrated at one place, and the damage degree of the cable is quickened. The number of the second mounting holes 20 can also be adjusted according to actual requirements.
As shown in fig. 6, the abutting portion 41 of the abutting structure 4 disposed at the first mounting hole 10 is used for sequentially penetrating through the first mounting hole 10 and the second mounting hole 20 to fasten (abutting or fasten or compress) the cable 3 in the blind hole 21, the abutting portion 41 is mounted on the mounting portion 40, and the mounting portion 40 is provided with a clamping groove 42 for adapting and clamping with the protrusion 12.
As shown in fig. 1, 7 and 8, 4 through holes 11 are formed in the connector body 1,4 cables 3 and 4 connecting terminals 2 can be respectively arranged at the 4 through holes 11, 2 second mounting holes are formed in each connecting terminal 2, and two first mounting holes communicated with the through holes 11 are formed at each through hole 11.
As shown in fig. 4 and 5, the abutting structure 4 includes 8 abutting portions 41 provided on the mounting portion 40, and at least two adjacent abutting portions 41 are connected by the mounting portion 40 to form an abutting structure 4 having at least two paths for abutting against the cable 3 inserted into the terminal 2.
The connector of the metering box is designed for matching with a second installation-level wiring of a single-phase electric energy meter, and comprises a connector body 1, a wiring terminal 2, a cable 3 for incoming or outgoing wires and a crimping cover plate formed by an installation part 40 and a butting part 41, wherein the wiring terminal 2 is shown in fig. 8. After the incoming and outgoing cables 3 are connected to the wiring terminal 2, the crimping cover plate is buckled, so that the clamping of the internal clamping groove 42 is ensured, the 8 metal posts (as the rod parts of the abutting parts 41) of the crimping cover plate can buckle the cables entering the wiring terminal, and the complex steps of disassembling 8 screws and fixing 8 screws are omitted.
