Referring to fig. 1 to 3, a sensor fixing bracket 100 is provided according to an embodiment of the present disclosure. The sensor fixing bracket 100 is used to mate with a mounting hole of an electric device (not shown). The sensor fixing bracket 100 includes a centering head 110, a connecting portion 120, and a fixing member 130.

In the present embodiment, the electric device is, for example, a circuit breaker, and the sensor is, for example, a rotation angle sensor for measuring an angular velocity. The circuit breaker has a mounting hole on a mounting surface. The sensor fixing bracket 100 is adapted to be fitted with the mounting hole to fix the sensor to the circuit breaker so that the sensor performs angular velocity measurement of the circuit breaker when the circuit breaker is operated.

The centering head 110 is adapted to be inserted into the mounting hole. The cross-sectional shape of the centering head 110 is a regular polygon or a circle, and the centering head 110 can be adapted to the mounting hole with different outer diameters. One end of the connecting portion 120 is used for being abutted with the sensor, and the other end is fixedly connected with the centering head 110. The fixing assembly 130 is used for fixedly connecting the connection portion 120 with the power equipment.

Specifically, one end of the connection part 120 is used to be inserted into the sensor, so that the connection part 120 is docked with the sensor. The other end of connecting portion 120 and centering head 110 fixed connection to after the mounting hole cooperation of centering head 110 and circuit breaker, rethread fixed subassembly 130 is with connecting portion 120 and circuit breaker fixed connection, then can make sensor and circuit breaker fixed, so that the sensor tests the circuit breaker.

Because the external diameter size of centering head 110 and the mounting hole looks adaptation of circuit breaker, and the shape of the cross section of centering head 110 is regular polygon or circular to when the mounting hole cooperation of centering head 110 and circuit breaker, centering head 110 can with the mounting hole in, and then the sensor can with the mounting hole in, so that realize the sensor and aim at the center of the in-process that tests the speed, guarantee the test data degree of accuracy.

The diameters of the mounting holes are different for different types of circuit breakers. Because the centering head 110 can be matched with the mounting holes with different outer diameters, the centering head 110 can be matched with the mounting holes for the mounting holes with different diameters, and the centering head 110 can be matched with the mounting holes for the mounting holes with different diameters, so that the centering of the sensor and circuit breakers of different models is realized.

In the sensor fixing bracket 100, one end of the connecting portion 120 is in butt joint with the sensor, and the other end of the connecting portion 120 is fixedly connected with the centering head 110, so that after the centering head 110 is matched with the mounting hole of the power equipment, the connecting portion 120 is fixedly connected with the power equipment through the fixing component 130, and the sensor can be fixed with the power equipment. Because the centering head 110 can be matched with the mounting holes of the power equipment by different outer diameters, the centering head 110 can be matched with the mounting holes of the power equipment for the mounting holes with different diameters, so that the centering of the sensor and the power equipment with different models can be realized, the universality of the sensor fixing support 100 is improved, and the sensor fixing support 100 can be suitable for the power equipment with different models when the power equipment is tested, and the testing efficiency is improved.

Referring to fig. 1 to 3 and 5, the outer diameter of the centering head 110 is gradually decreased along the direction in which the centering head 110 is inserted into the mounting hole.

Specifically, since the outer diameter of the centering head 110 is gradually reduced along the direction in which the centering head 110 is inserted into the mounting hole, the opening of the mounting hole is smaller for the mounting hole with a smaller diameter, and the smaller outer diameter of the centering head 110 can be adapted to the opening of the mounting hole by inserting the centering head 110 into the mounting hole at a shallower position. For the mounting hole with a larger diameter, the opening of the mounting hole is larger, and the centering head 110 is inserted into the deeper part of the mounting hole, so that the larger outer diameter part of the centering head 110 can be matched with the opening of the mounting hole. Therefore, the centering head 110 can be matched with mounting holes with different diameters by adjusting the depth of the centering head 110 inserted into the mounting holes, and the centering head is convenient and quick.

As shown in fig. 1 to 3 and 5, in the present embodiment, the centering head 110 is conical. It is understood that the centering head 110 may also be shaped as a truncated cone, a right pyramid, or a right frustum.
