Preferably, the metal terminal is equipped with notch, and the terminal box is equipped with the block of insertion notch.

Preferably, the notch is equipped with contraposition buckle, and contraposition buckle and gear close to metal terminal head side Block cooperation.

Preferably, the terminal box is equipped with retention bead, the pcb board, which is equipped with, protrudes into limit for retention bead Limit hole.

Preferably, the limit hole is arranged in pcb board bottom side.

Preferably, the registration holes are identical as locking hole size.

Preferably, the terminal box interior shape and current transformer shape match.

Using the above structure compared with prior art, the utility model has the advantage that structure electric current this first is mutual Sensor is fixed than stronger, it is not easy to joyous to move or touch other devices, better user experience.

And this structure can first assemble current transformer and terminal box, later again by limit hole and limit convex It rises and is matched, realize the contraposition of terminal box and pcb board, such current transformer can directly block after being installed on terminal box Enter onto pcb board, production process can be reduced in this way, reduce working hour, improves production efficiency.

Specific embodiment

The utility model is described further below in conjunction with attached drawing and specific embodiment, but the utility model is not only It is limited to following specific embodiments.

As shown in Figure 1, a kind of intelligent electric energy meter, including current transformer 1, pcb board 2 and terminal box 3, wherein

As shown in Fig. 2, being pcb board 2, it is equipped with locking hole 7 and limit hole 12 above, and limit hole 12 is that setting exists 2 bottom side of pcb board；

As shown in figure 3, being terminal box 3, it has a protruding portion above, and protruding portion is equipped with registration holes 6, and is aligning A block is additionally provided with before hole 6, and block side is equipped with the slot passed through for metal terminal, and on terminal box 3 also There are two retention beads 11 for setting, are separately positioned at left and right sides of terminal box；

As shown in figure 4, being current transformer, he includes copper post 4 and the metal terminal being arranged in copper post 45, the application Metal terminal 5 can be fixed in copper post 4 using welding form, such one-pass molding reduces impedance, so that metering is reliable Property is got higher；Or metal terminal 5 is riveted in copper post 4, and riveting point is two；And metal terminal 5 is close to front end It is equipped with a notch 8 at portion, and also sets up a contraposition buckle 10 at notch 8, and 5 front end of metal terminal is smaller；

When assembling three, first current transformer 1 is installed on terminal box 3 first, 5 front end of metal terminal is worn at this time The slot on 3 protruding portion of terminal box is crossed, the registration holes 6 being then then passed through on protruding portion, the block 9 on protruding portion can be embedded at this time Contraposition buckle 10 in notch 8, and on notch 8 can block main block 9, be equivalent to pacify current transformer 1 and terminal box 3 in this way Dress is together；Later by terminal box retention bead 11 be aligned pcb board 2 on limit hole 12, then by terminal box 3 with Pcb board 2 carries out contraposition installation, then can snap onto the locking hole 7 on pcb board 2 across 5 front end of metal terminal of registration holes 6 at this time Locking.
