Description

Technical Field

[0001] This utility model relates to the field of wind turbine accessories technology, specifically a motor junction box structure. Background Technology

[0002] A fan is a type of driven fluid machinery that relies on input mechanical energy to increase gas pressure and discharge gas. Its working principle is to drive the impeller to rotate through power equipment such as motors, so that the gas can gain energy, thereby increasing the gas pressure and realizing the gas transportation. The junction box is an accessory that connects and fixes the motor's junction box to the motor housing, keeping the junction box in a proper position and ensuring a stable and reliable connection between the motor and the external circuit.

[0003] Currently, most junction box sockets are installed separately from the junction box, usually in the form of a plate. During installation, they are installed in the order of fan housing, junction box socket, and junction box, which makes the installation cumbersome. In addition, the wires need to pass through the through holes on the junction box socket and housing to connect to the motor. During the operation of the motor, the wires are prone to displacement in the through holes. In this case, the wires are prone to wear, cracking, or even breakage, which reduces the service life of the wires. Utility Model Content

[0004] The purpose of this utility model is to provide a motor junction box structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor junction box structure, comprising: a box body; a connecting seat, fixedly disposed on the box body, wherein the interior of the connecting seat is connected to the interior of the box body, the cross-section of the connecting seat is trapezoidal, the contact surface of the connecting seat is arc-shaped, and the contact surface of the connecting seat is smaller than the cross-section of the box body; and a wire outlet sleeve, fixedly disposed on the contact surface of the connecting seat, wherein the interior of the wire outlet sleeve is connected to the interior of the connecting seat.

[0006] Preferably, it further includes: an inlet, extending through the housing; a lead sleeve, fixedly disposed within the inlet, the lead sleeve being used to protect the circuit; an adjusting sleeve, disposed on the lead sleeve, the adjusting sleeve being threadedly engaged with the lead sleeve; a shrinkage groove, disposed on the lead sleeve, the shrinkage groove being located inside the adjusting sleeve when the adjusting sleeve is engaged with the lead sleeve; and a pressing bevel, disposed inside the adjusting sleeve; wherein when the adjusting sleeve is rotated, the lead sleeve penetrates into the adjusting sleeve, and under the action of the pressing bevel, the lead sleeve deforms towards the shrinkage groove position, thereby fixing the circuit.

[0007] Preferably, it also includes: anti-slip texture, formed on the adjusting sleeve.

[0008] Preferably, it further includes: a slot formed on the connecting seat, the slot being located at the edge of the mating surface; and a sealing rubber ring disposed on the slot, the sealing rubber ring deforming when the connecting seat is fixed to the fan housing.

[0009] Preferably, it further includes: a thickened base, fixedly disposed on the connecting base; and a mounting through hole, which is formed through the thickened base and penetrates the mating surface of the connecting base.

[0010] Preferably, it further includes: a reinforcing rib, fixedly disposed on the box body, the reinforcing rib being connected to the connecting seat.

[0011] Preferably, it further includes: a protective rubber ring, fixedly installed inside the cable outlet sleeve; and a sealing ring, fixedly installed at the top of the housing.

[0012] This utility model provides a motor junction box structure, which has the following advantages:

[0013] (1) By setting up the connector and the cable outlet sleeve, this utility model can make the connector and the box into a whole, which is convenient for installation. It can also prevent the line from directly contacting the through hole on the fan housing when it enters the fan. This effectively avoids the line from being damaged or broken due to friction with the edge of the through hole during long-term use, thus effectively improving the service life of the line. Furthermore, by designing the connector to have an arc-shaped contact surface and a contact surface size smaller than the box, the junction box can fit with the surface of the fan housing of different sizes, enhancing its practicality.

[0014] (2) By setting up a lead wire sleeve, an adjusting sleeve, a shrinkage box, and a pressing slope, this utility model can move the adjusting sleeve on the lead wire sleeve by rotating it. During the movement, the pressing slope presses the lead wire sleeve. After the lead wire sleeve deforms, its cross-sectional area is deformed, which fixes the line and effectively avoids the external pulling on the line from directly acting on the connection between the line and the fan, which may cause short circuits or breakages, thus effectively reducing the failure rate of the line.
