And the unlocking member 320 enables the locking member 233 to be rapidly changed in position to accomplish smooth installation of the single-phase electric meter.

As shown in fig. 1, the cable interfaces 120 in this embodiment are respectively distributed in the epitope mounting slots 231a, and the anti-misoperation handle 310 is disposed at one side of the epitope mounting slot 231a. The epitope base 210 in this embodiment is provided with 6 epitope mounting grooves 231a.

As shown in fig. 2, the engaging structure 230 in this embodiment includes a connecting sleeve 231 and a connecting head 232, wherein the connecting sleeve 231 is disposed in the epitope mounting groove 231a and has an inlet and a plugging cavity facing outward, and two connecting sleeves 231 are disposed in each epitope mounting groove 231a. The connector 232 is disposed on a side of the single-phase electric meter facing the epitope mounting groove 231a, and when the single-phase electric meter is mounted in the epitope mounting groove 231a, the connector 232 enters the plugging cavity and is locked by the locking member 233.

Specifically, as shown in fig. 2, a limiting plate 232a is disposed on the connecting head 232 in this embodiment, after the connecting head 232 enters the connecting sleeve 231, the limiting plate 232a contacts the locking member 233 and is limited by the locking member 233, so as to limit the limiting plate 232a in the inserting cavity 231b, and temporarily place the connecting head 232 and the connecting sleeve 231 apart.

Preferably, the position-limiting plate 232a is a boss formed protruding on the sidewall of the connecting head 232, and has a first position-limiting surface 232a-1 thereon; the locking member 233 comprises a latch member 233a movably disposed along a direction perpendicular to the inlet and outlet direction of the connector 232, and the latch member 233a has a second limiting surface 233a-1; when the connector 232 enters the insertion cavity 231b, the second limiting surface 233a-1 contacts the first limiting surface 232a-1, and the second limiting surface 233a-1 is located outside the first limiting surface 232 a-1.

The limiting plate 232a is a boss which is formed on the side wall of the connecting head 232 in a protruding mode, a first limiting surface 232a-1 is arranged on the boss, the boss is annular and is uniformly perpendicular to the axial plane of the connecting shaft, and the first limiting surface 232a-1 is one surface, facing the outer side of the inserting cavity 231b, of the boss. The buckle 233a is movably disposed in the mounting groove 231a inside the connecting sleeve 231 along a direction perpendicular to the moving direction of the connecting head 232, the buckle 233a is provided with a second limiting surface 233a-1, the mounting groove 231a is a slot formed in the inner side wall of the connecting sleeve 231, and the extending direction of the slot allows the buckle 233a to move along the direction perpendicular to the moving direction of the connecting head 232. As shown in fig. 2 and fig. 3, after the connecting head 232 enters the plugging cavity 231b, as the connecting head 232 moves further into the plugging cavity 231b, when the first position-limiting surface 232a-1 on the position-limiting plate 232a moves closer to the inside of the plugging cavity 231b than the second position-limiting surface 233a-1, the latch 233a moves towards the connecting head 232 to contact the second position-limiting surface 233a-1 with the first position-limiting surface 232a-1, so as to block the movement of the position-limiting plate 232a towards the outside, and thus the connecting head 232 can be temporarily retained in the plugging cavity 231b.

In order to keep the latch 233a in a state of protruding out of the mounting groove 231a, a return spring 323 is further provided between the latch 233a and the mounting groove 231a, and the return spring 323 applies a pushing force to the latch 233a to move to the outside of the mounting groove 231a. Simultaneously still be equipped with the unblock button on adapter sleeve 231, the activity of unblock button inlays and locates on adapter sleeve 231 outer wall, its direction of motion is the same with buckle spare 233a, be connected through traction band 322 between unblock button and buckle spare 233a, the activity groove and the mounting groove 231a intercommunication of unblock button, the middle part of traction band 322 and the spacer butt between activity groove and the mounting groove 231a, when unblock button is pressed, traction band 322 will drive buckle spare 233a to the inside removal of mounting groove 231a, thereby with buckle spare 233a withdrawal mounting groove 231a, reserve the position for limiting plate 232a gets into grafting chamber 231b.

A guide portion 232b, which is a protrusion having an inclined first guide surface 232b-1 formed on the position limiting plate 232a, is further provided on the position limiting plate 232 a; the first guide surface 232b-1 faces the outlet side of the plug-in cavity 231b, and the buckling piece 233a is provided with a second guide surface 233a-2 parallel to the first guide surface 232 b-1; the second guiding surface 233a-2 faces the inside of the inserting cavity 231b, and as shown in fig. 3, when the connecting head 232 moves out of the inserting cavity 231b, the first guiding surface 232b-1 and the second guiding surface 233a-2 contact each other, and when the connecting head 232 continues to move outward, the first guiding surface 232b-1 drives the latch 233a to move away from the limiting plate 232a, so that the latch 233a retracts into the mounting groove 231a, and the connecting head 232 can move out of the inserting cavity 231b.

In order to make the limiting plate 232a move out of the plugging cavity 231b only at a specific position, as shown in fig. 3, the snapping member 233a in this embodiment is disposed in the mounting groove 231a on the inner wall of the connecting sleeve 231, the guiding parts 232b are symmetrically disposed on two symmetrical sides of the limiting plate 232a, and the first guiding surface 232b-1 and the second guiding surface 233a-2 are both sloped. When the connecting head 232 rotates to a specific position, the guiding portion 232b faces the latch 233a, the first guiding surface 232b-1 and the second guiding surface 233a-2 can be opposite to each other, and at this time, the connecting head 232 is pulled out to be interlocked with the latch 233a, so that the latch 233a is forced to move back.

As shown in fig. 3, the unlocking member 320 in this embodiment is an unlocking rod 321 disposed parallel to the axial direction of the connection sleeve 231, one end of the unlocking rod 321 is connected to the fastener 233a through a pulling belt 322, and the other end protrudes out of the table base 210, so that when the unlocking rod 321 moves in the opposite direction toward the inside of the connection sleeve 231, the fastener 233a is driven to retract into the installation groove 231a.

When the unlocking rod 321 is pressed inwards, the traction belt 322 drives the fastener 233a to move towards the inside of the mounting groove 231a, so that the fastener 233a retracts into the mounting groove 231a, a position is reserved for the limiting plate 232a to enter the inserting cavity 231b, and the connector 232 can conveniently enter the connecting sleeve 231.

In order to control the angular position of the connection head 232, the interlocking structure 330 is provided between the anti-misoperation handle 310 and the connection head 232, and as shown in fig. 2 and 4, the end of the connection head 232 is provided with an abutting part 232c.
