The folded plate 322 is in a shape of a zigzag plate, one end of the folded plate 322 is fixedly connected with the side wall of the connecting plate 321, the folded plate 322 is arranged on the same side as the side of the connecting plate 321 with the cut angle, and the folded plate 322 is arranged on the side wall of the connecting plate 321 without the cut angle. The bottom of the flap 322 is flush with the bottom of the web 321. Thereby, the structure of the mover 300 is further optimized. And the folded plate 322 is arranged to be in a Z-shaped structure and can be matched with the cover body at the bottom of the electric meter, so that the anti-theft function is achieved.

Here, it should also be noted that in one possible implementation, the abutment 310 is trapezoidal in cross section in the vertical direction.

In one possible implementation, the elastic member 400 is a spring.

In one possible implementation, the ratio of the length of the moving insert rod 200 to the length of the fixed insert rod 100 is between 1/2 and 4/5, and the length of the fixed block in the fixed insert rod 100 in the axial direction of the second expansion link 120 is smaller than the length of the moving insert rod 200. Further, when the ratio of the length of the moving insert rod 200 to the length of the fixed insert rod 100 is 3/5, that is, the length of the moving insert rod 200 is 37mm, the fixed insert rod 100 may be 60mm, and the length of the fixed block in the axial direction of the second expansion rod 120 may be 36 mm.

As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 7, fig. 8, fig. 9 or fig. 10, the present disclosure also provides an electric meter plug connector based on any one of the push-pull structures described above. The electric meter plug connector of the embodiment of the present disclosure includes the push-pull structure and the base 500 as described above, wherein the base 500 is provided with the installation cavity 510, one side of the installation cavity 510 is provided with an opening, the fixed plug rod 100 is detachably installed inside the installation cavity 510, and part of the fixed plug rod 100 extends out of the installation cavity 510. The base 500 is provided with a slide 520, the slide 520 is communicated with the mounting cavity 510, the slide 520 is arranged along the axial direction of the fixed inserted rod 100, and the moving member 300 is slidably connected with the slide 520. Therefore, in the embodiment of the present application, the movable rod 200 can be driven by pushing the moving element 300 on the sliding way 520 to move in the fixed rod 100, and when the movable rod 200 moves to a certain position, the elastic element 400 is pressed by the abutting part 310, and the elastic element 400 drives the movable rod 200 to move. From this, get this application embodiment and the inseparabler of the contact of the socket of ammeter, solved the untight problem of fixed inserted bar 100's head and ammeter connection that leads to because of the machining error of fixed inserted bar 100 and ammeter, avoided contact failure's the condition.

Here, it should be noted that in one possible implementation, the first expansion rod 230 of the fixing insert rod 100 is disposed to extend out of the mounting cavity 510 from the opening of the mounting cavity 510.

Furthermore, in a possible implementation manner, the fixing device further includes a fixing member, the fixing insert rod 100 is provided with a mounting hole 140, the mounting hole 140 is disposed beside the sliding groove 110, the mounting cavity 510 is provided with a surrounding hole 530, the surrounding hole 530 is disposed opposite to the mounting hole 140, and the mounting hole 140 is disposed inside the surrounding hole 530. The fixing member is detachably mounted on the mounting hole 140, and the fixing member is abutted to the hole wall of the surrounding and blocking hole 530. Thus, the fixing insert rod 100 can be detachably mounted on the mounting cavity 510 by the above-described structure.

Here, it should be noted that, in one possible implementation manner, the fixing member may be implemented by using a bolt, which is not described herein.

Here, it should also be noted that in another possible implementation, a hole may be opened at the mounting cavity 510, such that a bolt penetrates the hole on the mounting cavity 510 and the mounting hole 140, thereby detachably connecting the fixing insert rod 100 and the mounting cavity 510.

In one possible implementation, there are more than two mounting cavities 510, and the more than two mounting cavities 510 are arranged side by side. The number of the slide ways 520 is matched with the number of the mounting cavities 510, and the slide ways 520 are arranged in one-to-one correspondence with the mounting cavities 510. Each mounting cavity 510 is detachably mounted with a fixed insert rod 100.

Further, in a possible implementation, there are four mounting cavities 510, so that the structure of the embodiment of the present application and the structure of the electric meter are more matched.

In one possible implementation, the slide 520 penetrates through the side wall of the mounting cavity 520 along the axial direction of the second expansion rod 230, so that a T-shaped opening is formed in the side wall of the mounting cavity 520 opposite to the opening of the mounting cavity, and the T-shaped opening is matched with the sliding block 330. Thereby, the moving amplitude of the moving member 300 is increased, and the structure of the embodiment of the present application is optimized.
