In some implementations, the securing member 4 is a resilient structure.

The elastic structure may be a structure capable of elastic deformation, and by setting the fixing piece 4 to be an elastic structure, the fixing piece 4 excessively matched in the first groove 1111 can absorb the vibration and the impact suffered by the detecting element 3 through the elastic deformation of the fixing piece under the state of abutting against the detecting element 3, thereby being beneficial to reducing the influence of the external impact on the detecting element 3, reducing the possibility of damage to the detecting element 3 and improving the reliability of the detecting element 3.

Illustratively, the fixing member 4 may be made of rubber, so that the fixing member 4 has a good elastic deformability, and is capable of buffering vibrations and shocks received by the detecting element 3. The fixing piece 4 can also be made of foam, so that the fixing piece 4 can buffer vibration and impact received by the detecting element 3, and the fixing piece 4 can firmly support the detecting element 3 on the wall of the first groove 1111.

In some embodiments, the detecting element 3 comprises a temperature measuring element, and a portion of the fixing member 4 protrudes out of the first recess 1111 and contacts the electrical element 2.

The temperature measuring element may be a thermistor, which can detect the temperature at the electrical element 2, so that a user can grasp the temperature state of the distribution box 30 in time. By making the part of the fixing member 4 connected with the detecting element 3 extend out of the first groove 1111 and contact with the electrical element 2, the temperature of the electrical element 2 can be conducted to the detecting element 3 through the fixing member 4, so that the temperature measured by the detecting element 3 is closer to the temperature of the electrical element 2, and the accuracy of detecting the temperature by the detecting element 3 is improved.

In some embodiments, the fixture 4 comprises a thermal pad, at least part of which is clamped between the detection element 3 and the electrical element 2.
