Description

Technical Field

[0001] The utility model relates to a quick disconnect device, in particular to a fixing frame for the quick disconnect device. Background Art

[0002] To facilitate wiring, multiple terminal blocks are provided on the side walls of the base of the rapid disconnect housing. Since the terminal blocks are much thicker than the wires of the switching switch and are arranged in multiple rows, the base height of the housing will be much higher than the height of the internal switching switch and other components. Therefore, a fixing column is required in the base of the housing, and the switching switch and other components are fixed on the fixing column.

[0003] For example, Chinese patent application number 202311373392.1 discloses a rapid disconnect device, including an upper cover and a base. The base is provided with an inner cavity, in which a circuit board is provided. The inner cavity is integrally formed with a fixing column facing the upper cover, and a connector is assembled on the fixing column. The connector includes a protective end and an installation end. A motor is assembled at the installation end, and a switch is assembled at the protective end. The output end of the motor is inserted into and assembled on the switch. A wiring terminal is provided on one side of the base, and the wiring terminal has multiple slots and is equipped with a wiring terminal.

[0004] The above scheme has the following defects: the installation direction of the switching switch and the connector is different from the installation direction of the switching switch and the motor output terminal on the connector. The switching switch is installed on the connector in the vertical direction, but the switching switch must be coordinated with the output terminal of the motor on the connector in the horizontal direction, which will lead to poor coordination and stability between the switching switch and the motor output terminal, and more troublesome assembly; small fast disconnectors usually only have one or two switching switches, and there are fewer internal wires and terminal blocks installed on the base of the shell, but large-scale string-level fast disconnectors will be equipped with multiple switching switches, resulting in a large number of wires, which not only affects wiring but also makes subsequent maintenance more troublesome. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing bracket for a quick disconnector which is more convenient to install, does not affect the reliability of use, and is convenient for wire arrangement and maintenance.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a fixing bracket for a quick disconnect device, comprising a fixing plate for supporting a transfer switch, wherein the fixing plate is supported on a plurality of fixing legs, and the two ends of the fixing legs are detachably fixed to the fixing plate and the shell by fasteners respectively, and the edge of the fixing plate is provided with a plurality of positioning grooves arranged at intervals along the extension direction of the outer edge of the fixing plate, the positioning grooves deviate from the fixing legs, the positioning grooves are laterally open and pass through the fixing plate up and down, the positioning grooves include an inner section of the positioning groove located deep in the positioning groove and an outer section of the positioning groove located at the opening, the width of the outer section of the positioning groove is smaller than the width of the inner section of the positioning groove, and the positioning groove is L-shaped.

[0007] The utility model is provided with a fixing plate, which can first coordinate the switching switch with the motor output end, and then fix the switching switch and the motor on the fixing plate, thereby ensuring the stability of the fixation between the switching switch, the motor and the fixing plate, making installation more convenient and ensuring reliability in use.

[0008] The fixing plate is used to support the transfer switch, while the fixing legs support the fixing plate. This design allows the fixing frame to adapt to different models of quick disconnects. The fixing plate and fixing legs can be detachably fixed to the housing by fasteners, providing flexibility and adaptability. By replacing fixing legs of different heights, it can adapt to quick disconnects of different heights.

[0009] The fixing plate of this utility model is provided with an L-shaped positioning slot on the edge. The width of the outer section of the positioning slot is slightly smaller than the diameter of the wire, so that the outer sheath of the wire can be elastically deformed and snapped into the inner section of the positioning slot. The positioning slot positions the wires extending from the upper and lower sides of the diverter switch, ensuring the regularity of the wires. Each diverter switch module can be equipped with a fixing plate, avoiding the messy wires caused by a large number of diverter switches. It also facilitates the alignment of the wires with the terminal blocks and facilitates subsequent maintenance.

[0010] Preferably, the end surface of the fixing plate is provided with several U-shaped protrusions arranged side by side. The U-shaped protrusions and the fixing legs are located on the same side of the fixing plate, and the U-shaped protrusions form a through slot that runs through the front and back. The U-shaped protrusions form a through slot that runs through the front and back, which is used to position the power cord of the motor, improving the flexibility of wire arrangement and the convenience of maintenance.

[0011] Preferably, a window extending vertically through one of the front and rear ends of the fixing plate is provided, the window being located between two adjacent left and right fixing legs, and the window being located in front of or behind the U-shaped protrusion. Providing a window on the fixing plate facilitates the downward extension of the motor power cord to the underside of the fixing plate.

[0012] Preferably, a plurality of positioning grooves are provided on both the left and right opposite sides of the fixing plate. The above arrangement increases the flexibility of the wire arrangement and facilitates the introduction and fixation of the wires.

[0013] Preferably, the fixing plate has a boss extending in the middle away from the fixing leg, with a receiving slot defined within the boss, the opening of the slot being oriented opposite to the extension of the boss. The boss can be used to elevate the position of a switch or other component, ensuring coaxiality between the switch and the matching slot at the motor output terminal.

[0014] Preferably, the fixing leg comprises a first leg section for connection to the fixing plate and a second leg section for fixed connection to the housing. The first leg section is provided with a laterally opening clearance slot extending along the extension direction of the fixing leg. The second leg section is provided with a mating hole for mating with a fastener, the clearance slot communicating with the mating hole. The first leg section is provided with a lateral opening to facilitate installation of a screw fastener through the clearance slot, thus facilitating securement of the fixing leg to the housing even when the space within the housing is limited.

[0015] Preferably, the width of the first section of the support leg gradually decreases from the fixed plate side to the second section of the support leg side.

[0016] The utility model has the advantages of being more convenient to install, not affecting the reliability of use, and being convenient for wire arrangement and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
