[0040] This invention provides a sensor bracket 100 that can be quickly plugged into and connected to a controller 70 without the need for additional adapters or cables. It features a simple structure and is easy to assemble.

[0041] Please see Figures 1-3The sensor bracket 100, used to connect the sensor 60 and the controller 70, includes a bracket body 10, a circuit board 20, a connecting terminal 30, and wires 40. The circuit board 20 is disposed on the bracket body 10 and is used to connect the sensor 60. The connecting terminal 30 is disposed on the bracket body 10 and is used to connect the controller 70. The wires 40 connect the circuit board 20 and the connecting terminal 30 respectively. Since the connecting terminal 30 is used to connect with the controller 70, the unique plug-in mating method of the connecting terminal 30 allows the connecting terminal 30 and the controller 70 to be connected through a simple plug-in mating. Therefore, the sensor bracket 100 enables quick assembly of the sensor 60 and the controller 70 and simplifies the connection structure between the two.

[0042] In some embodiments, the bracket body 10 includes a connecting portion 18 and a mounting portion 19, which are integrally disposed. The inner wall of the mounting portion 19 and the inner wall of the connecting portion 18 define a cavity. A wire 40 is installed in the cavity, with one end for connecting to the circuit board 20 and the other end for connecting to the connection terminal 30.

[0043] The bracket body 10 has a protrusion 11 on the side facing the circuit board 20. The circuit board 20 has a connection hole 21. The protrusion 11 is inserted into the connection hole 21, so that the bracket body 10 and the circuit board 20 are fixedly connected and easy to disassemble.

[0044] In some embodiments, the protrusion 11 is hollow and has a mating hole 111. The sensor bracket 100 also includes a connector. The connector, protrusion 11, mating hole 111 and connection hole 21 are all coaxially arranged. The connector passes through the connection hole 21 on the circuit board 20 and extends into the mating hole 111 of the protrusion 11, thereby realizing the connection between the protrusion 11 and the circuit board 20.

[0045] In some embodiments, the connector is provided as a screw or bolt, etc.

[0046] In some embodiments, two protrusions 11 are provided and are spaced apart at both ends of the sensor bracket 100.

[0047] In some embodiments, the bracket body 10 has a mounting groove 12 on the side facing the circuit board 20, and the circuit board 20 is disposed in the mounting groove 12.

[0048] In addition, after the bracket body 10 and the circuit board 20 are connected by the cooperation of the protrusion 11 and the connection hole 21, the structural strength of the connection can be further improved by bonding or welding between the groove wall of the mounting groove 12 and the circuit board 20.

[0049] The bracket body 10 is provided with a wiring groove 13, which is opened at the bottom of the mounting groove 12 facing the circuit board 20. The wire 40 is connected to the circuit board 20 through the wiring groove 13. In this way, the wire 40 can pass out from multiple positions in the wiring groove 13 and connect to the circuit board 20, and the wiring groove 13 facilitates the routing of the wire 40.

[0050] In some embodiments, the wiring channel 13 extends from the connecting portion 18 to the mounting portion 19 and extends along the length direction of the mounting portion 19. In this embodiment, the wire 40 passes through the end of the wiring channel 13 away from the connecting portion 18 and is electrically connected to the circuit board 20.

[0054] In some embodiments, the first limiting block 15 extends from one end of the support body 10 to the other end to improve structural strength and increase the contact area between the support body 10 and the motor pump to which it is applied.

[0055] The bracket body 10 has at least one second limiting block 16 on the side facing away from the circuit board 20. The second limiting block 16 is connected to the first limiting block 15, and protrudes from the first limiting block 15 along the direction away from the circuit board 20. The second limiting block 16 further improves the structural strength of the first limiting block 15, and the protrusion of the second limiting block 16 from the first limiting block 15 allows for circumferential limiting.

[0056] In some embodiments, the bracket body 10 has two second limiting blocks 16 on the side facing away from the circuit board 20. The two second limiting blocks 16 are respectively connected to the two ends of the first limiting block 15 to provide stronger limiting performance.
