Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to an alloy moment terminal. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections. They are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the use of terminal blocks has become more and more diverse. Alloy torque universal terminal blocks are suitable for the connection between various round, semi-circular, and fan-shaped wires and power cables in power distribution devices.

[0003] After searching, the utility model with announcement number CN217114856U discloses an alloy torque universal terminal, including a terminal body and an aluminum pad. One end of the terminal body has a connecting plate, and the connecting plate is provided with a connecting hole. The other end of the terminal body has a wiring tube. The aluminum pad is arranged in the wiring hole of the wiring tube. The terminal body is provided with a torque bolt matched with the aluminum pad. One end of the aluminum pad has a positioning block, and a positioning groove is arranged at the corresponding positioning block in the wiring hole. The positioning block is engaged in the positioning groove, and forms a limit fit between the aluminum pad and the wiring tube. The utility model has the advantages of simple structure, stable and reliable performance, convenient assembly, and reliable connection.

[0004] The terminal block also has the following disadvantages during use: the wire is clamped and fixed by torque bolts and spacers during use, but the wire body is usually set to be multi-stranded, and the torque bolts and spacers will separate the multi-stranded wire body when clamping the wire, causing it to deform and affect the contact between the wire body and the wiring hole, and the torque is not easy to control. When the torque is large, it is easy to cause the wire body to break, and when the torque is small, the installation is not firm. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art that the wire body is usually set as multiple strands, and the torque bolt cooperates with the spacer to separate the multiple strands of the wire body when clamping the wire, causing deformation, affecting the contact between the wire body and the wiring hole, and the torque is not easy to control. When the torque is large, it is easy to cause the wire body to break, and when the torque is small, the installation is not firm. The alloy torque terminal is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The alloy moment terminal comprises a terminal body, wherein the terminal body is composed of a connecting plate and a connecting cylinder, wherein the connecting plate and the connecting cylinder are connected via a transition portion, which is used to convert the arc surface on the connecting cylinder into a flat surface, thereby increasing the contact area between the connecting cylinder and the terminal block;

[0008] An inner cylinder, the inner cylinder is inserted into the connecting cylinder, a plurality of bolts are provided through the top of the connecting cylinder through threads, the bottoms of the bolts are in conflict with the inner cylinder, and the inner cylinder is deformed to clamp the wire in the connecting cylinder;

[0009] The positioning mechanism is arranged in the connecting tube and is used to limit the position of the inner tube in the connecting tube.

[0010] In a possible design, the positioning mechanism includes two positioning grooves opened on the inner wall of the connecting tube, and the limiting strips are inserted into the positioning grooves. The two limiting strips are fixed on the outer wall of the inner tube and are used to limit the angle of the inner tube. A positioning hole corresponding to the bolt is opened on the top of the upper limiting strip.

[0011] In a possible design, one end of the inner cylinder is sealed, and the other end is fixedly sleeved with a retaining ring, which abuts against the connecting cylinder to limit the position of the inner cylinder. Rectangular openings are provided on the outer sides of the inner cylinder and the retaining ring, which can make the inner cylinder open and be used to change the diameter of the inner cylinder.

[0012] In a possible design, a conductive ring is embedded on the top of the connecting plate to increase the conductivity of the connecting plate and the terminal block, and a limiting portion is provided on the bottom of the connecting plate to increase the friction between the connecting plate and the terminal block.

[0013] In a possible design, a serrated groove is provided on the inner side of the positioning groove and the outer side of the limiting strip to increase the friction between the connecting tube and the inner tube.

[0014] In a possible design, a transition portion is provided at one end of the limit strip for cooperating with the positioning groove to guide the inner tube.

[0015] In the present application, when in use, the insulating layer outside the wire is peeled off, and then the inner tube is put on the wire. When the wire diameter is larger than the inner tube, the inner tube can be opened by both hands, and then the connecting tube is plugged into the inner tube, and the limiting strip is plugged into the positioning groove. During the plugging process, the positioning groove and the serrated groove inside the limiting strip can be used for limiting contact until one side of the retaining ring contacts the connecting tube. Then the bolt is rotated to move the bolt downward on the connecting tube. During the movement, the bolt can be inserted into the positioning hole to further limit the inner tube. Continuing to rotate the bolt can drive the inner tube to deform and fix the wire.

[0016] Finally, by inserting the fastening bolt into the conductive ring and screwing the connecting plate onto the terminal block, the limiting part will come into conflict with the terminal block during the screwing process, thereby increasing the friction between the terminal block and the connecting plate.

[0017] In the utility model, the alloy moment terminal is provided with an inner cylinder in the connecting cylinder, and the diameter of the inner cylinder can be changed, so that wires of different thicknesses can be inserted into the inner cylinder, and when the inner cylinder is compressed, the wires can be protected so that they will not break or loosen.

[0018] In the utility model, the alloy moment terminal can limit the inner tube through the coordinated use of the positioning groove and the limiting strip, which can effectively prevent the bolt from contacting the rectangular opening and affecting the connection strength, and can also increase the friction between the connecting tube and the inner tube through the sawtooth groove inside the positioning groove and the sawtooth groove at the bottom of the limiting strip, so that the plug-in is more secure;

[0019] In the utility model, by arranging an inner cylinder in the connecting cylinder, not only the wires can be bound, but also the wires can be protected during installation to avoid damage to the wires. At the same time, the wires can be easily installed in the connecting cylinder, which can improve the wiring efficiency and is more convenient and quick to use. BRIEF DESCRIPTION OF THE DRAWINGS
