Preferably, the through-hole quantity of terminal box bottom is more than one, and is sharp equidistance distribution, and correspondingly, the spacing post and the through-hole one-to-one of drain pan bottom.

Preferably, the through-hole shape is square, and spacing post is cuboid or prismatic, and square through-hole and cuboid or prismatic cooperation back, the contact surface is great, has strengthened spacing post bearing capacity, if for circular through-hole and the cooperation of cylindrical spacing post, the contact point is very little, and spacing post atress area is little, easy rupture.

Preferably, the limiting column extends out from the bottom of the bottom shell, and the strength of the limiting column is enhanced.

Preferably, terminal button box bottom is equipped with round arc seal groove, and the seal groove is located between through-hole and the drain pan center, is equipped with soft sealing strip in the seal groove, prevents that the water of outside from passing through inside the through-hole gets into the electric energy meter.

The utility model relates to an electric energy meter anti-theft structure, its terminal box is installed on the drain pan, the bottom is equipped with spacing post in the drain pan, terminal box bottom is equipped with the through-hole, the terminal box is installed behind the drain pan, spacing post just in time extends to in the through-hole and extends to the binding post circular through-hole terminal surface department of terminal box, just in time kept off on binding post base and terminal box circular through-hole, make the terminal block base unable to move outwards along the circular through-hole, thereby avoid the terminal block to break away from the terminal box by the drag effort, prevent the terminal block from being stolen; in addition, a circle of sealing groove is formed in the periphery of the through hole, a sealing strip is arranged in the sealing ring, water is prevented from entering the through hole from the outside, and water enters the electric energy meter along the through hole.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figure 1, the utility model provides an electric energy meter anti-theft structure, which comprises a bottom shell 1, an end button box 2, a pulse row and a cover cap 3, wherein the cover cap 3 comprises a monitoring window 4 and a flip cap 5, the cover cap 3 is arranged on the bottom shell 1, the end button box 2 comprises a fixed seat 6 and a connecting terminal 7, the fixed seat 6 is detachably embedded at the inner lower end of the bottom shell 1, the pulse row is connected above the fixed seat 6, the front and the back of the fixed seat 6 are provided with circular through holes 8, the circular through holes 8 transversely penetrate through the front and the back of the fixed seat 6, the connecting terminal 7 is arranged in the circular through holes 8, the base 10 of the connecting terminal 7 is columnar, the connecting terminal 7 is transversely arranged in the circular through hole 8 of the fixed seat 6 towards the center direction of the bottom shell 1, so that the upper end surface of the base 10 is flush with the end surface of the circular through hole 8 of the fixed, as shown in fig. 2, the bottom of the bottom shell 1 under the through hole 9 extends out of a vertical limiting post 11, as shown in fig. 3, the terminal box 2 is installed behind the bottom shell 1, the limiting post 11 is inserted into the through hole 9, and the end portion of the limiting post extends to the end face of the base 10 of the wiring terminal 7 to serve as a barrier at the circular through hole 8 and the base 10, so that the base 10 of the wiring terminal 7 cannot move outwards along the circular through hole 8, and the wiring terminal 7 is prevented from being separated from the terminal box 2 due to the dragging force.
