Description

Technical Field

[0001] This utility model relates to the field of power metering equipment technology, specifically to intelligent terminal wiring terminals. Background Technology

[0002] In the field of electricity metering, traditional smart terminals generally use a direct bolt connection method to achieve electrical connection between external wires and the internal terminals of the electricity meter. Specifically, the smart terminal terminal block has a threaded wiring hole. During installation, the operator inserts the exposed end of the wire into the wiring hole and then screws a bolt into it. The axial force generated by tightening the bolt directly presses and clamps the wire placed in the wiring hole, thereby achieving mechanical fixation and electrical continuity of the wire.

[0003] Although this method is simple in structure and widely used, in actual use, especially in long-term operation and complex working conditions, the pressure generated by tightening the bolt is directly applied to a small local area of ​​the wire (usually the end of the bolt or a small washer). If there is an external force pulling, the wire can easily be pulled out of the connector. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a smart terminal wiring terminal to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The intelligent terminal wiring terminal includes a terminal and a terminal block located at its bottom. The terminal block has an axial cavity with an open operating side. A pressure plate is rotatably connected to the open side. A crimping member is provided at the bottom of the pressure plate facing the cavity to hold the wire. A wiring hole is opened at the wiring end of the terminal block. A platform is provided near the wiring hole at the edge of the open side. The platform has a platform screw hole that communicates with the wiring hole. A pressure plate screw hole is opened at the position of the platform. Bolts pass through the pressure plate screw hole and the platform screw hole in sequence to press the wire against the inner wall of the wiring hole.

[0007] Preferably, the crimping member has a concave structure, and the radius of the concave surface is smaller than the radius of the wiring hole.

[0008] Preferably, the crimping member has a convex structure, and the vertex of the convex surface does not exceed the axis of the wiring hole when the pressure plate is closed.

[0009] Preferably, the crimping component has a block structure, and the bottom surface of the block does not exceed the axis of the wiring hole when the pressure plate is closed.

[0010] Preferably, the bottom of the crimping component is provided with several anti-slip strips.

[0011] Preferably, the platform protrudes towards the operating side, and the axis of the platform screw hole intersects with the axis of the wiring hole.

[0012] Preferably, the two ends of the pressure plate are rotatably connected to the shaft holes on both sides of the terminal block via pins.

[0013] Preferably, when the pressure plate is closed, the crimping member extends into the cavity and corresponds to the wire pressing area. When the bolt is tightened, the pressure plate rotates downward around the pin shaft, so that the crimping member presses the wire tightly to the bottom of the cavity.

[0014] This utility model provides a smart terminal wiring terminal. It has the following beneficial effects:

[0015] 1. Through the combined action of the pressure plate and bolts, the wire is double-fixed in both the pressure area and the connection area, which greatly improves the tensile strength and prevents the wire from loosening.

[0016] 2. The crimping parts adopt a variety of structural designs, combined with anti-slip strips, to increase the contact area and friction with the wires and prevent displacement caused by long-term vibration. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See attached document Figure 1-6 The intelligent terminal wiring terminal includes a terminal 1 and multiple terminal blocks 2 disposed at the bottom of the terminal 1;

[0026] Terminal block 2 has a chamber extending along its axial direction, the chamber having an opening facing the operating side, and a pressure plate 3 is rotatably provided at the opening of terminal block 2, and the pressure plate 3 can cover the opening of terminal block 2.

[0027] A wiring hole 21 communicating with the terminal block 2 is provided at the wiring end of the terminal block 2. The wiring hole 21 is the wiring area and the cavity is the wire pressing area. A platform 22 is also provided near the wiring area at the opening of the terminal block 2. A platform 22 protruding towards the operating side is provided at the edge of the opening of the terminal block 2 near the entrance of the wiring hole 21. A platform screw hole 23 is provided on the platform 22. The axis of the platform screw hole 23 intersects the axis of the wiring hole 21, and the platform screw hole 23 is in communication with the wiring hole 21.

[0028] Opposite shaft holes 24 are provided on the two side walls of the open edge of the terminal block 2 near the wire pressing area. Pins 31 are fixedly provided at both ends of the pressure plate 3. The pins 31 are rotatably inserted into the shaft holes 24, thereby rotatably connecting the pressure plate 3 to the terminal block 2.

[0029] A pressing member 33 is provided on the bottom of the pressure plate 3. The pressing member 33 is located on the inner side of the pressure plate 3 facing the cavity. When the pressure plate 3 is closed, the pressing member 33 extends into the cavity and corresponds to the pressing line area.

[0030] The crimping member 33 has a concave structure, and the radius of the concave surface is smaller than the radius of the wiring hole 21 to ensure that the wire is crimped tightly.

[0031] The crimping member 33 has a convex structure, and the vertex of the convex surface does not exceed the axis of the wiring hole 21 when the pressure plate is closed, so as to avoid obstructing the insertion of the wire;

[0032] The crimping member 33 has a block structure, and the bottom surface of the block structure does not exceed the axis of the wiring hole 21 when the pressure plate is closed, so as to avoid obstructing the insertion of the wire;

[0033] The bottom of the crimping component 33 is provided with several anti-slip strips to increase the friction with the wire.

[0034] A pressure plate screw hole 32, which is consistent with the platform screw hole 23, is provided on the pressure plate 3 at the position corresponding to the platform 22. The bolt first passes through the pressure plate screw hole 32 and then through the platform screw hole 23, pressing the wire against the inner wall of the wiring area of ​​the terminal block 2. The wire is fixed together by the action of the bolt and the crimping member 33.

[0035] Working principle: During wiring, first rotate and open the pressure plate 3, inserting the exposed end of the wire to be connected into the cavity of the terminal block 2 through the wiring hole 21. Then, rotate the pressure plate 3 to close it over the opening of the terminal block 2. At this time, the crimping member 33 on the pressure plate 3 is located above the wire in the cavity. Pass the bolt through the screw hole 32 of the pressure plate and screw it into the platform screw hole 23 on the platform 22. Tighten the bolt; the tension generated by the bolt pulls the pressure plate 3 towards the platform 22, forcing the pressure plate 3 to rotate downward around the pin 31, thereby causing the crimping member 33 to move downward, firmly pressing the wire into the crimping area of ​​the cavity. The anti-slip strip at the bottom of the crimping member 33 enhances friction and prevents the wire from loosening. The locking action of the bolt maintains the closed state of the pressure plate 3 and the continuous pressure of the crimping member 33 on the wire, achieving reliable electrical connection and mechanical fixation of the wire.
