[0027] Example 1

[0028] like Figure 1 As shown, an embodiment of the present invention provides an over-temperature feedback transformer clamp, comprising: a connection body 100 and a temperature detector 200; the connection body 100 includes: a wire connection portion 110 and a transformer connection portion 120; the temperature detector 200 is connected between the wire connection portion 110 and the transformer connection portion 120, and the temperature detector 200 generates electrical changes based on the temperature of the wire connection portion 110, the transformer connection portion 120, and the temperature between the wire connection portion 110 and the transformer connection portion 120. The wire connection portion 110 is connected to the power transmission line, and the transformer connection portion 120 is connected to the transformer terminal. The temperature detector 200 is located between the wire connection portion 110 and the transformer connection portion 120. Increases in the temperature of the transformer terminal or the power transmission line can be transmitted to the temperature detector 200, thereby ensuring more accurate temperature detection. The temperature detector 200 can use a temperature sensor. When the temperature changes, the resistance value of the temperature-sensitive components within the temperature detector 200 changes, thereby changing the electrical properties of the temperature detector 200.

[0029] Specifically, the wiring body 100 is integrally formed and made of metal. The temperature detector 200 is located between the wire connection portion 110 and the transformer connection portion 120, and the wire connection portion 110 and the transformer connection portion 120 respectively abut the temperature detector 200. Whether the temperature of the wire connection portion 110 or the transformer connection portion 120 increases, the temperature detector 200 can detect the temperature increase.

[0030] In this embodiment of the present invention, a mounting portion 111 is provided between the wire connection portion 110 and the transformer connection portion 120. The mounting portion 111 is adapted to fit the temperature detection device 200. The mounting portion 111 includes a mounting hole or a groove, into which the temperature detection device 200 is inserted. This not only ensures full contact between the wiring body 100 and the temperature detection device 200, thereby improving heat transfer efficiency, but also prevents the temperature detection device 200 from protruding outward from the surface of the wire connection portion 110, thereby allowing the wiring body 100 and the temperature detection device 200 to be installed compactly.

[0031] like Figure 1 、 Figure 2and Figure 3 As shown, the temperature detection device 200 has a terminal, and the terminal is located below the temperature detection device 200. The terminal is located below the temperature detection device 200, and the wire connected to the temperature detection device 200 extends downward from the terminal. When rainwater hits the wire and flows along the wire, the rainwater will not flow to the terminal of the temperature detection device 200 due to gravity.

[0032] Furthermore, the wire connecting portion 110 is provided with a wire installation hole 101 and a wire pressing hole connected to the wire installation hole 101 , and a wire pressing piece 300 for pressing the wire is provided in the wire pressing hole.

[0033] Specifically, the wire pressing member 300 includes: a first wire pressing bolt 310 and a second wire pressing bolt 320. The first wire pressing bolt 310 and the second wire pressing bolt 320 respectively cooperate with the connecting wire connecting part 110. The transmission line is inserted into the wire mounting hole 101. The first wire pressing bolt 310 and the second wire pressing bolt 320 respectively abut the transmission line. By tightening the first wire pressing bolt 310 and the second wire pressing bolt 320 respectively, the transmission line inserted into the wire mounting hole 101 can be fixed.

[0034] Furthermore, the transformer connecting portion 120 is provided with a transformer mounting hole 102 and an opening groove 103 connected to the transformer mounting hole 102; a locking member 400 is provided on the transformer connecting portion 120, and the locking member 400 is used to reduce the opening of the opening groove 103, thereby reducing the radial size of the transformer mounting hole 102.

[0035] In some embodiments, the locking member 400 is a spring clip that clamps the transformer connection portion 120 , thereby causing the opening of the opening slot 103 to have a tendency to shrink, thereby reducing the radial size of the transformer mounting hole 102 , and further clamping the transformer terminal in the transformer mounting hole 102 .

[0036] In this embodiment, the open slot 103 divides the transformer connection portion 120 into two clamping blocks. The locking member 400 is a locking bolt. The locking bolt passes through one of the clamping blocks, and the end cap of the locking bolt abuts against the clamping block. The other end of the locking bolt is matingly connected to the other clamping block. Tightening the locking bolt can bring the two clamping blocks closer together, and loosening the locking bolt in the opposite direction causes the two clamping blocks to move away from each other due to elastic action. The transformer terminal is inserted into the transformer mounting hole 102. Tightening the locking bolt can reduce the opening of the open slot 103, thereby clamping the terminal in the transformer mounting hole 102.

[0037] Furthermore, the locking member 400 includes: a first locking bolt 410 and a second locking bolt 420. The first locking bolt 410 and the second locking bolt 420 are arranged at intervals along the axial direction of the transformer mounting hole 102, and the axis of the first locking bolt 410 and the axis of the second locking bolt 420 are respectively perpendicular to the axis of the transformer mounting hole 102. By tightening the first locking bolt 410 and the second locking bolt 420 respectively, the opening of the opening groove 103 is reduced, thereby ensuring that the terminal is firmly clamped in the transformer mounting hole 102.

[0038] Furthermore, the wire mounting hole 101 extends along a first direction, and the transformer mounting hole 102 extends along a second direction. The angle between the first and second directions is 80 to 100 degrees. The transformer's terminal is inserted into the transformer mounting hole 102 along the second direction. When the over-temperature feedback transformer clamp is in use, the terminal body 100 is positioned above the transformer, and the power line is inserted into the wire mounting hole 101 along the first direction. The axis of the wire mounting hole 101 is nearly horizontal, thereby preventing rainwater from entering the wire mounting hole 101 along the power line. To facilitate processing and positioning, the axis of the wire mounting hole 101 is perpendicular to the axis of the transformer mounting hole 102.

[0039] like Figure 3 、 Figure 4 and Figure 5 As shown, the over-temperature feedback transformer clamp further includes a clamp housing 500, which defines an inner cavity for accommodating the wiring body 100 and the temperature detection device 200. The clamp housing 500 is made of an insulating material. By encasing the wiring body 100 and the temperature detection device 200, the clamp housing 500 protects the wiring body 100 and the temperature detection device 200 from rain, thereby ensuring circuit safety.

[0040] Furthermore, the top of the clamp housing 500 is connected to a communication device 600, which is connected to the temperature detector 200 via a signal line. The communication device 600 is configured to change its output signal based on the signal from the temperature detector 200. When the temperature of the wiring body 100 exceeds a preset temperature, the communication device 600 generates an alarm based on the signal from the temperature detector 200, thereby remotely alerting maintenance personnel to inspect the circuit.

[0041] Furthermore, the clamp housing 500 includes a clamp bottom cover 510 and a clamp cover 520. The wiring body 100 is connected to the clamp bottom cover 510, and the clamp cover 520 is fitted over the wiring body 100. The clamp bottom cover 510 and clamp cover 520 are detachably connected. The connection between the wiring body 100 and the clamp bottom cover 510 prevents the wiring body 100 from moving within the clamp housing 500. The clamp bottom cover 510 and clamp cover 520 are connected via snaps or bolts. By separating the clamp bottom cover 510 and clamp cover 520, the temperature detector 200 can be inspected and replaced.

[0042] like Figure 1 、 Figure 2 and Figure 4 As shown, the wiring body 100 is provided with a first latching position 104 and a second latching position 105. The cable clamp bottom cover 510 includes a base portion 511 and a skirt portion 512 connected to the base portion 511. The skirt portion 512 is sleeved over the wiring body 100 to prevent it from shaking. Furthermore, the skirt portion 512 is connected to a first latching block 513 and a second latching block 514. The first latching block 513 engages with the first latching position 104, and the second latching block 514 engages with the second latching position 105. The first latching block 513 engages with the first latching position 104, and the second latching block 514 engages with the second latching position 105, thereby securing the wiring body 100 to the cable clamp bottom cover 510.

[0043] like Figure 4 and Figure 5 As shown, the outer side of the skirt 512 is connected to a third clamping block 515, a fourth clamping block 516, a fifth clamping block 517, and a sixth clamping block 518. The bottom of the wire clamp cover 520 is open and has a first clamping port 524, a second clamping port 525, a third clamping port 526, and a fourth clamping port 527. The third clamping block 515, the fourth clamping block 516, the fifth clamping block 517, and the sixth clamping block 518 are correspondingly engaged with the first clamping port 524, the second clamping port 525, the third clamping port 526, and the fourth clamping port 527. In addition, the wire clamp cover 520 is also provided with a fifth clamping port 523, and the second clamping block 514 is engaged with the fifth clamping port 523. The wire clamp bottom cover 510 is located below the wire clamp cover 520 , and the opening of the wire clamp cover 520 is covered with a skirt 512 , thereby preventing rainwater from seeping into the wire clamp cover 520 along the gap between the wire clamp bottom cover 510 and the wire clamp cover 520 .

[0044] like Figure 3 and Figure 6 As shown, the temperature detection device 200 includes a temperature control switch, and the communication device 600 uses a signal transmitter. The signal transmitter is controlled by the temperature control switch. When the temperature of the wiring body 100 is higher than the preset temperature, the signal transmitter sends a wireless signal to the server, and the server controls the warning light or sound generator to prompt the staff to inspect the circuit.

[0045] Furthermore, the communication device 600 includes: a signal transmission circuit board 630, a first connector 640 and a second connector 650, wherein the first connector 640 and the second connector 650 are respectively connected to the signal transmission circuit board 630, and the temperature detection device 200 is connected to the signal transmission circuit board 630 via a signal line. Among them, the first connector 640 and the second connector 650 are both waterproof connectors, and the first connector 640 and the second connector 650 are connected to the positive and negative terminals of the power supply in a one-to-one correspondence. The communication device 600 also includes: a junction box 610 and a top cover 620, wherein the junction box 610 has a receiving cavity for accommodating the signal transmission circuit board 630, and the side wall of the junction box 610 is provided with two through holes, and the first connector 640 and the second connector 650 are inserted into the two through holes in a one-to-one correspondence. The top cover 620 covers the top of the junction box 610, and the top cover 620 and the junction box 610 are connected by screws.

[0046] Furthermore, the top of the clamp cover 520 is provided with a third latching position 521 and a fourth latching position 522. The junction box 610 is provided with a first latching portion 611 and a second latching portion 612. The first latching portion 611 is adapted to fit within the third latching position 521, while the second latching portion 612 is adapted to fit within the fourth latching position 522. With the first latching portion 611 engaged with the third latching position 521 and the second latching portion 612 engaged with the fourth latching position 522, the junction box 610 can be connected to the top of the clamp cover 520. The top cover 620 and the junction box 610 form a sealed box, protecting the signal transmission circuit board 630 from damage due to rain. Removing the top cover 620 facilitates inspection and maintenance of the signal transmission circuit board 630.

[0047] Example 2

[0048] like Figure 3 As shown, the transformer clamp assembly method provided by an embodiment of the present invention includes: connecting a temperature detection device 200 between a wire connection portion 110 and a transformer connection portion 120; wherein the wire connection portion 110 is used to connect a power transmission line, and the transformer connection portion 120 is used to connect a transformer. Specifically, the temperature detection device 200 located between the wire connection portion 110 and the transformer connection portion 120 can detect the temperature of the transformer and the power transmission line, thereby making temperature detection more accurate. In addition, the connection terminal of the temperature detection device 200 is located at the bottom of the temperature detection device 200, one end of the signal line is connected to the connection terminal of the temperature detection device 200, and the other end of the signal line extends and is connected to the communication device 600. The communication device 600 is arranged above the connection body 100. Even if rainwater flows along the signal line, the rainwater will not flow to the connection terminal of the temperature detection device 200, thereby preventing the temperature detection device 200 from being damaged by rain.
