[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only two parts of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 , is a schematic diagram of the structure of the electric energy meter connection socket provided by the present invention.

[0034] This embodiment provides an electric energy meter terminal socket, comprising a housing 1, a test probe assembly 2, a connection line (not shown in the figure) for electrically connecting to a test device, and a clamping mechanism 4;

[0035] The test probe assembly 2 is arranged at the bottom of the housing 1, and the outer wall of the housing 1 is provided with a connection port 3 for allowing a connection line to pass through, and the connection line is electrically connected to the test probe assembly 2;

[0036] The clamping mechanism 4 includes two clamping assemblies 41 of the same structure, which are respectively arranged on opposite sides of the shell 1. The clamping assembly 41 includes a clamping part 411 and a rotating part 412 for clamping on the back of the electric energy meter. The rotating part 412 can drive the clamping part 411 to rotate horizontally.

[0037] It should be noted that when testing the electric energy meter, the rotating part 412 of the electric energy meter socket is rotated to drive the clamping part 411 to rotate horizontally, so that the clamping part 411 is in a non-clamping position, that is, a position offset from the electric energy meter, and then the test probe assembly of the electric energy meter socket is aligned with the corresponding wiring screw on the electric energy meter and pressed. After pressing to a certain position, the rotating part 412 of the electric energy meter socket is rotated to drive the clamping part 411 to rotate horizontally, so that the clamping part 411 is clamped to the back of the electric energy meter, and the electric energy meter socket is clamped to the electric energy meter by the rebound force of the test probe assembly 2 and the two clamping assemblies 41. At this time, the connecting wire of the electric energy meter socket is connected to the test equipment for testing. When replacing and testing different electric energy meter faults, there is no need to frequently disassemble the wiring. You only need to separate the electric energy meter terminal block from the original electric energy meter and snap it into the new electric energy meter. It is easy to operate. The connection between the test equipment, the electric energy meter terminal block and the electric energy meter is firm, thereby improving the detection efficiency and safety and reliability of the electric energy meter.

[0038] Among them, a gap of 2mm deep according to the national standard is provided at the bottom of the one-way smart energy meter, and the clamping component 411 can be inserted into the gap of 2mm deep according to the national standard at the bottom of the energy meter, so that the connection between the energy meter terminal block and the energy meter is more secure.

[0039] Furthermore, the electric energy meter terminal socket further comprises a clamping mechanism 5, the clamping mechanism 5 comprises a crimping shaft 51 and a crimping handle 52, and the crimping handle 52 is provided with a shaft hole 521 and an elliptical rotating protrusion 522;

[0040] The crimping shaft 51 passes through the shaft hole 521 and is connected to two opposite sides of the top of the housing 1 . The top of the housing 1 is provided with an elliptical rotating track 111 that matches the elliptical rotating protrusion 522 .

[0041] During specific implementation, the crimping handle 52 is rotated upward along the crimping shaft 51, and the elliptical rotating protrusion 522 of the crimping handle 52 rotates against the elliptical rotating track 111 on the top of the shell 1, thereby pressing the shell 1 downward again, making the connection between the electric energy meter terminal socket and the electric energy meter more stable.

[0042] It should be noted that the clamping mechanism 4 and the pressing mechanism 5 are used to realize the double crimping of the electric energy meter terminal socket, and only a small force is needed to easily clamp the electric energy meter terminal socket and the electric energy meter firmly, which is more labor-saving, convenient and quick.

[0043] Furthermore, a closing limit hook 112 is provided on the top of the shell 1 , and a closing limit groove 523 cooperating with the closing limit hook 112 is provided on the crimping handle 52 .

[0044] It should be noted that when the electric energy meter test is not needed, the crimping handle 52 is placed close to the top of the shell 1, and the closing limit hook 112 on the top of the shell 1 is buckled into the closing limit groove 523 on the crimping handle 52 to fix the crimping handle 52.

[0045] See also Figure 3 , is a schematic diagram of the structure of the test probe assembly of the electric energy meter connection socket provided by the present invention. Figure 1 and Figure 3 As shown, the test probe assembly 2 includes an incoming live line probe seat 21, an outgoing live line probe seat 22, a neutral line probe 23 and a signal probe 24, and the incoming live line probe seat 21, the outgoing live line probe seat 22, the neutral line probe 23 and the signal probe 24 are distributed and installed at the bottom of the housing 1;

[0046] The inlet probe seat 21 is provided with a plurality of inlet probes 211 , and the outlet probe seat 22 is provided with a plurality of outlet probes 221 .

[0047] It should be noted that the live wire probe seat 21 and the outgoing wire probe seat 22 need to pass a large current, and the terminals of the electric energy meter connected to them are two screws. By respectively arranging a number of live wire probes 211 and a number of outgoing wire probes 221 on the live wire probe seat 21 and the outgoing wire probe seat 22, the small probes can contact multiple surfaces of the screws, increasing the contact surface, thereby allowing a large current to pass. When the electric energy meter fails and needs to be repaired with a large current, it is not necessary to disassemble the electric energy meter and return it to the power supply department for repair, thereby improving the detection efficiency and reducing the detection cost. In addition, the live wire probe 211, the outgoing wire probe 221, the neutral line probe 23 and the signal probe 24 have a rebound force, so that together with the clamping mechanism 4, the electric energy meter terminal seat is clamped to the electric energy meter.

[0048] Among them, the numerous test probes of the power meter terminal socket are crimped with the power meter terminals to form an electrical connection, and the contact surface between the top of the test probe and the power meter terminal is used as the wire cross-sectional area to provide a path for current, thereby realizing a connection path that can allow large current to flow.

[0049] See also Figure 4 ,yes Figure 1 A schematic diagram of the structure from another angle. Figure 4 As shown, a positioning assembly 13 is further provided at the bottom of the housing 1, and the positioning assembly 13 includes a first positioning boss 131, a positioning pin 132 and a second positioning boss 133;

[0050] The first positioning boss 131 and the second positioning boss 133 are respectively located at the edges of the test probe assembly 2 , and the positioning pin 132 is located inside the test probe assembly 2 .

[0053] It should be noted that the positioning assembly 13 composed of the first positioning boss 131, the positioning pin 132 and the second positioning boss 133 forces the electric energy meter terminal socket to quickly and smoothly align with each terminal of the electric energy meter for electrical connection. The live wire probe 211 is connected to the live wire terminal of the electric energy meter, the live wire probe 221 is connected to the live wire terminal of the electric energy meter, the neutral wire probe 23 is connected to the neutral wire terminal of the electric energy meter, and the signal probe 24 is connected to the signal terminal of the electric energy meter. The live wire, live wire, signal wire terminal 33 and neutral wire are respectively connected to the live wire probe socket 21, the live wire probe socket 22, the signal probe 24 and the neutral wire probe 23 in a one-to-one correspondence, thereby realizing the electrical connection between the test equipment and the electric energy meter.

[0054] In an embodiment of the present invention, the wiring port 3 may further include a live wire wiring port 31 for allowing the live wire to pass through, a live wire wiring port 32 for allowing the live wire to pass through, a signal wire wiring port 33 for allowing the signal wire to pass through, and a neutral wire wiring port 34 for allowing the neutral wire to pass through, so as to distinguish different connecting wires; connecting terminals for plugging into the test equipment may also be respectively provided at the tail ends of the live wire, the live wire, the signal wire and the neutral wire, so that wiring is more convenient and quick; wire buckle protective covers may also be respectively provided at the live wire wiring port 31, the live wire wiring port 32, the signal wire wiring port 33 and the neutral wire wiring port 34 to protect the connecting wires from being broken.

[0055] See also Figure 5 , is a structural schematic diagram of the clamping mechanism of the electric energy meter terminal socket provided by the present invention; see Figure 6 , is a schematic structural diagram of the upper cover of the electric energy meter connection socket provided by the present invention.

[0056] like Figure 4 and 5 As shown, the housing 1 is provided with rotation holes 14 on two opposite sides;

[0057] The clamping member 411 of the clamping assembly is an L-shaped fixed card, and the rotating member 412 of the clamping assembly includes a fixed clamping column 4121 and a knob 4122. The fixed clamping column 4121 is sleeved in the rotating hole 14, and the knob 4122 is installed on the housing 1 and can rotate horizontally relative to the housing 1.

[0058] The fixed card column 4121 includes a compression part 4121a and a fixed part 4121b. The compression part 4121a is provided with a knob compression spring 4123. The radial dimension of the knob compression spring 4123 is smaller than the diameter of the fixed part 4121b. The fixed card column 4121 is located at one end of the compression part 4121a and is fixedly connected to the knob 4122. One side of the L-shaped fixed card is fixed to the fixed part 4121b.

[0059] Furthermore, the housing 1 includes an upper cover 11 and a bottom cover 12. The upper cover 11 is provided with a cylindrical structure 141 on two opposite sides, and the bottom cover 12 is provided with a plug hole 142 on two opposite sides. When the upper cover 11 is covered with the bottom cover 12, the cylindrical structure 141 and the plug hole 142 together form a rotating hole 14.

[0060] The knob 4122 includes a knob cap 4122a and a rotating handle 4122b. The inner wall of the knob cap 4122a is provided with a rotation limiting groove 4122c. The outer wall of the cylindrical structure 141 is provided with a rotation limiting boss 1411 that cooperates with the rotation limiting groove 4122c. The knob cap 4122a is sleeved on the outer wall of the cylindrical structure 141.

[0061] It should be noted that when the knob cap 4122a is sleeved on the outer wall of the cylindrical structure 141, the rotation limit boss 1411 is inserted into the rotation limit groove 4122c. When the knob 4122 is rotated, the rotation limit boss 1411 can only move in the rotation limit groove 4122c, thereby limiting the rotation angle of the knob 4122. The preferred rotation angle in this embodiment is 90°.

[0062] Furthermore, if Figure 2 As shown, the crimping shaft 51 includes a crimping rod 511 and an annular crimping tray 512 disposed at both ends of the crimping rod 511;

[0065] It should be noted that when the crimping rod 511 is inserted into the rotating shaft hole 521, the crimping limit boss 513 is inserted into the crimping limit groove 5211. When the crimping handle 52 is rotated, the crimping limit boss 513 can only move in the crimping limit groove 5211, thereby limiting the rotation angle of the crimping handle 52. The preferred rotation angle in this embodiment is 90°.

[0066] The electric energy meter terminal socket provided by the present invention, when testing the electric energy meter, drives the clamping part to rotate horizontally by rotating the rotating part of the electric energy meter terminal socket, so that the clamping part is in a non-clamping position, and then presses the test probe assembly of the electric energy meter terminal socket to the corresponding wiring screw on the electric energy meter, and after pressing to a certain position, drives the clamping part to rotate horizontally by rotating the rotating part of the electric energy meter terminal socket, so that the clamping parts are respectively clamped on the back of the electric energy meter, and the electric energy meter connection socket is clamped on the electric energy meter by using the rebound force of the test probe assembly and two clamping assemblies. At this time, the connection line of the electric energy meter terminal socket is connected to the test equipment to carry out the test. When replacing and testing different electric energy meter faults, there is no need to frequently disconnect the wires. It is only necessary to separate the electric energy meter terminal socket from the original electric energy meter and clamp it to the new electric energy meter, which is easy to operate; the connection between the test equipment, the electric energy meter terminal socket and the electric energy meter is stable, thereby improving the detection efficiency and safety and reliability of the electric energy meter.
