Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, specifically to a temperature measurement terminal block for a power intelligent fusion terminal. Background Technology

[0002] In power systems, terminals are key components for connecting power equipment, undertaking the important tasks of current transmission and electrical connection. During power transmission, due to factors such as poor contact and overload, local overheating can easily occur at the terminals. Overheating can accelerate terminal aging, damage insulation, and even cause serious accidents such as fires, seriously affecting the safety and reliability of the power system. Therefore, temperature-sensing terminals have emerged. They monitor the terminal temperature in real time through built-in temperature sensors and transmit the data to an intelligent fusion terminal for analysis and processing, realizing intelligent monitoring and early warning of the terminal's operating status.

[0003] However, existing temperature measurement terminals also have certain limitations. They mainly insert wires through holes at both ends and use screws to tighten or loosen the wires. The structure is fixed, the wiring channel direction is singular, and it cannot flexibly adapt to the wire connection requirements of different layouts, resulting in inconvenient installation. To address this, we propose a power intelligent fusion terminal temperature measurement terminal. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See attached document Figure 1-7 A power intelligent fusion terminal temperature measurement terminal includes a first terminal 1 and a second terminal 2. A temperature sensor is embedded in the first terminal 1 (not shown in the figure) to collect the temperature inside the terminal. The temperature sensor is prior art and will not be described in detail in this application. The second terminal 2 can rotate around the outer wall of the first terminal 1 so that the angle between the wiring channels of the two terminals changes. This allows for flexible adjustment of the wiring direction according to the actual installation environment, greatly improving the convenience of installation and meeting the wire connection requirements of different layouts.

[0032] Both the first terminal 1 and the second terminal 2 are made of flame-retardant insulating plastic material, such as polycarbonate (PC).

[0033] In this embodiment, the first terminal 1 has a spherical structure with symmetrical circular cut surfaces 11 in the X, Y, and Z axes. These circular cut surfaces 11 provide support and positioning for the installation and rotation of the second terminal 2. The first wiring holes 12 are respectively opened in the X and Z axes, so that two mutually perpendicular wiring channels are formed on the first terminal 1. The second terminal 2 has a square structure with second wiring holes 21 passing through both sides. The second terminal 2 rotates around the outer wall of the first terminal 1, so that the end of the second wiring hole 21 is connected to the first wiring hole 12 in the X or Z axis direction of the first terminal 1. This increases the diversity of wire connection, meets the needs of wire connection in different directions, and improves installation flexibility.

[0034] In this embodiment, the second terminal 2 is provided with a circular groove 22 at one end of the second wiring hole 21, which matches the outer wall of the first terminal 1, so that one side of the second terminal 2 fits against the first terminal 1 and completely covers the end of the corresponding first wiring hole 12. By setting the circular groove 22, the connection between the second terminal 2 and the first terminal 1 is made tighter, which can better protect the end of the first wiring hole 12 from impurities and improve the safety of use.

[0035] In this embodiment, a pair of circular cross-sections 11 of the first terminal 1 along the Y-axis and the two sides of the second terminal 2 are connected by a pair of hinge components. The hinge components enable the second terminal 2 to rotate around the outer wall of the first terminal 1, thereby enabling the switching of the wire connection direction.

[0036] In this embodiment, the hinge assembly includes a hinge plate 3, a limiting block 4, and a fixing screw 5. A pair of circular cross-sections 11 in the Y-axis direction of the first terminal 1 and threaded holes 6 for screwing in the fixing screw 5 are provided on both sides of the second terminal 2. Insertion holes for inserting the thin end of the limiting block 4 are provided at both ends of the hinge plate 3. The limiting block 4 is in the shape of a stepped shaft and has insertion holes for inserting the fixing screw 5. By turning the fixing screw 5 screwed into the threaded hole 6, the thick sidewall of the limiting block 4 is made to fit against the outside of the hinge plate 3, so that both sides of the hinge plate 3 are locked onto the first terminal 1 and the second terminal 2 respectively. Turning the fixing screw 5 on both sides of the first terminal 1 makes the limiting block 4 no longer press against the hinge plate 3. At this time, the second terminal 2 can be rotated to realize the connection between the second wiring hole 21 and the first wiring hole 12 in different directions. After adjustment, tighten the fixing screw 5. The adjustment is convenient and efficient.

[0037] The axis of the threaded hole 6 on the first terminal 1 is collinear with the axis of the first terminal 1 in the Y-axis direction, so as to ensure that the second terminal 2 can rotate stably around the outer wall of the first terminal 1.

[0038] In this embodiment, a pair of fixing blocks 13 are provided in the first wiring hole 12 on the Z-axis of the first terminal 1. The pair of fixing blocks 13 are respectively located above and below the first wiring hole 12 in the X-axis direction. The lower fixing block 13 is internally threaded with a first wire pressing screw 14. The first wire pressing screw 14 is made of flame-retardant insulating plastic material, such as polycarbonate (PC).

[0039] The end of the first wire clamping screw 14 extends into the interior of the first wiring hole 12 to lock the wire inserted into the wiring channel of the first terminal 1. When the wire is inserted into the interior of the first wiring hole 12 in the X-axis direction, the first wire clamping screw 14 is tightened. At this time, the first wire clamping screw 14 can fix the wire and prevent the wire connection from becoming loose, which would lead to poor contact.

[0040] In this embodiment, a second wire clamping screw 23 is threadedly connected to one side of the second terminal 2. The second wire clamping screw 23 is made of flame-retardant insulating plastic material, such as polycarbonate (PC).

[0041] The end of the second wire clamping screw 23 extends into the interior of the second wiring hole 21. After the wire is inserted into the second wiring hole 21, the second wire clamping screw 23 is tightened. At this time, the second wire clamping screw 23 can fix the wire inserted in the wiring channel of the second terminal 2, so as to prevent the wire connection from becoming loose and causing poor contact.

[0042] In this embodiment, a sealing cover 15 is provided on the end of the first wiring hole 12 in the Z-axis direction. When the first wiring hole 12 in the Z-axis direction is not in use, it is sealed by the sealing cover 15 to prevent external dust from entering.

[0043] In this embodiment, in order to improve the sealing effect, annular grooves 16 are provided on three circular cross-sections 11 in the Z-axis direction and the X-axis direction near the second terminal 2. The annular grooves 16 are sleeved on the outside of the end of the first wiring hole 12. The sealing cover 15 is provided with an outer annular protrusion 151 that matches the annular groove 16 and an inner circular protrusion 152 that matches the inner cavity of the end of the first wiring hole 12. When it is necessary to change the wiring direction, the sealing cover 15 on the upper side in the Z-axis direction needs to be removed first, and then the second terminal 2 is rotated so that the second wiring hole 21 is perpendicular to the first wiring hole 12 in the X-axis direction. Then the removed sealing cover 15 is placed on the end of the first wiring hole 12 in the X-axis direction that matches it.

[0044] See attached document Figure 8 In this embodiment, a sealing sleeve 7 is provided on the side of the first wiring hole 12 away from the second terminal 2 and the side of the second wiring hole 21 away from the first terminal 1 on the X-axis. The narrow side of the sealing sleeve 7 is adapted to the inner diameter of the first wiring hole 12 and the second wiring hole 21. The sealing sleeve 7 is provided with a hole for the wire to pass through. When wiring, the wire will first pass through the corresponding sealing sleeve 7 respectively, and then connect together. After that, pull the connection to the middle position, tighten the first wire pressing screw 14 and the second wire pressing screw 23, and then insert the sealing sleeve 7 into the first wiring hole 12 and the second wiring hole 21 respectively to achieve a full seal.

[0045] Working principle: During installation, two wires are passed through the corresponding sealing sleeves 7, and then one of the wires is passed through the second wiring hole 21 and out through the front end of the first wiring hole 12 in the X-axis direction. At this time, the two wires are connected and tightened, and then electrical tape is wrapped around them. Next, the connection position of the wires is pulled into the middle position of the terminal block. The first wire clamping screw 14 and the second wire clamping screw 23 are tightened and fixed to the wires. Then, the sealing sleeves 7 are inserted into the first wiring hole 12 and the second wiring hole 21 respectively. At this time, the connection of the two wires is completed.

[0046] If the wiring direction needs to be adjusted, first remove the sealing cover 15 on the upper side of the Z-axis direction, then loosen the fixing screw 5 on the first terminal 1, and then rotate the second terminal 2. At this time, the second wiring hole 21 corresponds to the first wiring hole 12 in the Z-axis direction. Then tighten the fixing screw 5 on the first terminal 1 so that the first terminal 1 and the second terminal 2 are relatively fixed.

[0047] Pass the two wires through the corresponding sealing sleeves 7, insert one of the wires through the second wiring hole 21 and out through the front end of the first wiring hole 12 in the X-axis direction, then connect and tighten the two wires and wrap them with electrical tape. Next, pull the connection position of the connected wires into the middle position of the terminal block, and tighten the first wire clamping screw 14 and the second wire clamping screw 23 respectively to clamp and fix the wires. Then insert the sealing sleeves 7 into the first wiring hole 12 and the second wiring hole 21 respectively. Finally, install the removed sealing cap 15 at the rear end position of the first wiring hole 12 in the X-axis direction to seal it. At this time, the connection of the two wires is completed.
