In the above solution, the insertion direction of the copper sheet is perpendicular to the sliding direction of the ring interface.

In the above solution, the housing is provided with bolt adjustment holes, and the positions of the bolt adjustment holes correspond to the nuts of the bolts.

In the above solution, the housing is provided with a rear cover adapted to it, and the rear cover is connected to the housing through a buckle. After the housing is fastened with the rear cover, the joint is covered and inside the housing.

In the above solution, there are multiple groups of the ring interface and the bolts, each group has one ring interface and two bolts matching it, and the ring interfaces are arranged side by side along the inside of the housing.

In the above solution, the shape of the copper sheet is U-shaped, and each of the copper sheets is respectively pierced with two annular interfaces.

In the above solution, the socket is arranged on the bottom surface of the housing, and the position of the socket corresponds to the position of the annular interface.

In the above solution, the material of the ring interface is conductive metal.

In the utility model, the wire has a socket inserted into the shell and then enters the ring interface, and the side wall of the ring interface is clamped with the bolt by screwing the bolt, so that the wire and the copper sheet are firmly attached together, greatly enhancing the contact. The stability and contact area improve the working efficiency of the meter, the structure is simple and practical, and the replacement and disassembly are convenient.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Fig. 1 to Fig. 6, a kind of electric meter of new-type connection terminal provided by the utility model comprises electric meter body 9 and the connection terminal that is arranged in the electric meter body 9, and connection terminal comprises the casing 1 of rectangular parallelepiped shape and is arranged on casing 1 The connector in the housing 1 is provided with a socket 2 for the insertion of wires. The meter body 9 is detachably connected to the terminal by buckles or bolts and nuts. The socket 2 is located on the bottom surface of the housing 1. The ring interface 3 and the copper sheet 5 in 1, the copper sheet 5 is fixedly arranged in the shell 1, one end of the copper sheet 5 is installed in the ring interface 3, the other end of the copper sheet 5 is connected with the external electrical components, the socket 2 The position corresponds to the position of the ring interface 3. The housing 1 is provided with a card slot 6 adapted to the ring interface 3. The ring interface 3 can slide back and forth in the card slot 6. The insertion direction of the copper sheet 5 is the same as the sliding direction of the ring interface 3. Vertical, but the sliding range is limited by the copper sheet 5 worn, so that a screw hole is provided on the side wall of the annular interface 3, through which the bolt 4 is pierced on the annular interface 3, and the shell 1 is provided with Bolt adjustment hole 8, the position of bolt adjustment hole 8 is corresponding to the nut of bolt 4, just can easily adjust the tightness of bolt 4 by screwdriver like this. When the screw bolt 4 is inserted into or removed from the ring interface 3, the slidable ring interface 3 can then gradually clamp or loosen the wire, so as to realize a firm connection between the wire and the terminal.

In addition, after the wire is inserted into the ring interface 3 of the utility model, since the copper sheet 5 and the side wall of the ring interface 3 are in surface-to-face contact, compared with the traditional method of directly clamping the wire between the bolt head and the copper sheet 5 This method will be more firm and stable, and the wire will not run off and cut off the power, and after the side wall of the ring interface 3 is bonded to the copper sheet 5, the contact area with the wire is also smaller than that of a simple bolt fixing pressure The combination methods are greatly increased, so the work efficiency is also greatly improved.

Further preferably, the shell 1 is provided with a back cover 7 adapted thereto, and the back cover 7 is connected to the shell 1 through a buckle. The housing 1 is provided with a plurality of cooling grooves, which not only saves raw materials and prolongs the service life, but also prevents dust from entering the housing 1 .

As shown in Fig. 7 and Fig. 8, further preferably, in order to improve work efficiency, there may be multiple sets of ring joints 3 and bolts 4, and each set includes a ring joint 3 and two bolts 4 matching it, the ring joint 3 distributed side by side along the inside of the housing 1. The shape of the copper sheet 5 is preferably a U-shaped thin sheet, and each copper sheet 5 is respectively pierced with two annular interfaces 3, and the number of each component can also be set according to the specific actual usage.

The ring interface 3 is made of non-copper cheap conductive metal, which greatly saves the production cost and does not affect the smooth conduction.

In the utility model, the wire has a socket inserted into the shell and then enters the ring interface, and the side wall of the ring interface is clamped with the bolt by screwing the bolt, so that the wire and the copper sheet are firmly attached together, greatly enhancing the contact. The stability and contact area improve the working efficiency of the meter, the structure is simple and practical, and the replacement and disassembly are convenient.
