DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figures 1 to 4 As shown, a wiring assembly for a bus duct temperature sensor includes a sub-wiring assembly 3 for transmitting electrical signals of a bus duct temperature sensor 1 and a mother wiring assembly 4 for electrically connecting to an external device, wherein the sub-wiring assembly 3 includes:

[0036] The sub-binding post 31 is fixed to the output end of the bus duct temperature sensor 1.

[0037] A plug pin 34 is fixedly connected to the plug interface 33 provided on the sub-binding post 31 , and one end of the plug pin 34 is electrically connected to the circuit board in the bus duct temperature sensor 1 .

[0038] The threaded strip 32 is fixedly arranged on the outside of the sub-connecting post 31 .

[0039] The female wiring assembly 4 includes:

[0040] The connecting piece 42 is detachably fixed to the outside of the sub-connecting post 31 .

[0041] The power connection piece 41 is fixed in the wiring piece 42 and is used to electrically connect the bus duct temperature sensor 1 and an external device.

[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the power connection member 41 includes:

[0043] An electrical connection plug 411 is plugged into the plug port 33 , and one end surface of the electrical connection plug 411 is provided with an electrical connection socket 412 matching the plug pin 34 .

[0044] The external wire 413 is fixed to the other end of the power plug 411 , and one end of the external wire 413 passes through one end of the connecting member 42 , and one end of the external wire 413 is electrically connected to an external device.

[0045] like Figure 3 and Figure 4 As shown, in this embodiment, the connecting member 42 includes:

[0046] An outer retaining ring 421 is fixed to the outside of the power plug 411 .

[0047] The inner retaining ring 422 is fixed to the outside of the power plug 411 . The outer retaining ring 421 and the inner retaining ring 422 are both located at the same end of the power plug 411 , and the opposing surfaces of the two and a part of the surface of the power plug 411 enclose a limiting ring groove 423 .

[0048] The center ring 424 disposed in the limiting ring groove 423 is rotated.

[0049] The outer sleeve 425 is fixed to the outside of the center ring 424 . The inner wall of the outer sleeve 425 is provided with a thread groove 426 matching the thread strip 32 . The axial length of the thread groove 426 is greater than the axial length of the thread strip 32 and less than the inner axial length of the outer sleeve 425 .

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the connecting piece 42 includes a hollow sealing ring 427 fixedly sleeved in an external sleeve 425 , and one side of the hollow sealing ring 427 is bonded to one side of the inner retaining ring 422 .

[0051] Before the external sleeve 425 is threadedly connected to the sub-terminal 31, the power socket 412 is first aligned with the plug pin 34 in the sub-terminal 31. The alignment operation of the two can be observed by naked eyes and the circumferential position of the power connection part 41 is manually adjusted circumferentially so that the power socket 412 is aligned with the plug pin 34. The alignment efficiency of the two can also be improved by pre-setting alignment marks on the surfaces of the sub-terminal 31 and the external sleeve 425. Then, the threaded strip 32 on the outside of the sub-terminal 31 is threadedly connected to the thread groove 426 on the inner wall of the external sleeve 425 to achieve a fixed connection between the two until the external sleeve 425 cannot be twisted. At this time, the end face of the sub-terminal 31 abuts against one side of the hollow sealing ring 427 and squeezes it to produce elastic deformation, which can not only improve the connection firmness between the two through the elastic force accumulated by its elastic deformation, but also expand along the radial direction of the sub-terminal 31 to improve the sealing inside the external sleeve 425, achieving two goals at one stroke. In addition, during the above operation process, the circumferential rotation of the external sleeve 425 will not affect the power plug 411, and the power plug 411 still remains stationary in the circumferential direction, avoiding the threaded connection operation between the external sleeve 425 and the sub-terminal 31 affecting the docking accuracy between the power socket 412 and the plug pin 34.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the wiring assembly for the bus duct temperature sensor also includes two protection assemblies 2 for buffering the impact force when the bus duct temperature sensor 1 falls accidentally.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, the protection component 2 includes:

[0054] A vertical buffer ring 22 is fixedly sleeved on the side wall of the bus duct temperature sensor 1 , and a first buffer cavity 23 is provided in the vertical buffer ring 22 .

[0055] A horizontal buffer ring 21 is fixed on the bus duct temperature sensor 1, and its boundary is fixedly connected to the boundary of the vertical buffer ring 22. A second buffer cavity 24 is provided in the horizontal buffer ring 21, and the second buffer cavity 24 is connected to the first buffer cavity 23. A plurality of exhaust grooves 25 are provided on the upper surface of the horizontal buffer ring 21.

[0056] By threading the terminal block 42 and the sub-terminal block 3, the connection firmness between the external wire and the bus duct temperature sensor 1 is improved. When the bus duct temperature sensor 1 falls accidentally during installation, it can be pulled by the external wire to avoid the problem of separation at the connection between the terminal block 42 and the sub-terminal block 3. If the external wire is fixed firmly, the bus duct temperature sensor 1 can be prevented from falling to the ground. If the external wire is fixed firmly, the impact force of the bus duct temperature sensor 1 falling can be buffered, the probability of its crashing can be reduced, and a certain protective effect can be played. When it contacts the ground, the horizontal buffer ring 21 or the vertical buffer ring 22 contacts the ground and buffers the remaining impact force of the bus duct temperature sensor 1 falling through elastic deformation. No matter which side of the bus duct temperature sensor 1 contacts the ground, the protection component 2 can buffer and protect the bus duct temperature sensor 1, thereby improving the comprehensiveness of the protection of the bus duct temperature sensor 1.

[0057] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
