Referring to fig. 1 and 2, a fixing structure 100 for fixing a lead wire 101 of a transformer according to an embodiment of the present invention includes two fixing members 10 and two connecting units 20.

The two fixing members 10 are arranged at intervals along the first direction, the two connecting units 20 are arranged at intervals along the second direction, and the two connecting units 20 and the two fixing members 10 enclose each other to form a fixing space 102. The lead 101 is inserted into the fixing space 102, and the lead 101 can be initially limited by the two fixing members 10 and the two connecting units 20.

Wherein at least one of the two fixing members 10 can be controlled to approach each other, since the lead 101 is already confined in the fixing space 102, the approach of the two fixing members 10 can finally clamp the lead 101 in the fixing space 102 between the two fixing members 10 to further fix the lead 101, and thus the fixing of the lead 101 by the fixing structure 100 is completed. In this way, regardless of the specification of the lead wire 101, the lead wire 101 of the specification can be clamped by adjusting the distance between the two fixing members 10.

The fixing structure 100 primarily limits the lead 101 by the two fixing members 10 and the two connecting units 20 enclosing each other to form a fixing space 102. And then the two fixing pieces 10 are controlled to approach each other until the lead 101 in the fixing space 102 is clamped between the two fixing pieces 10, so that the lead 101 is fixed. Compared with the traditional fixing structure 100 of the lead 101, the fixing structure 100 can be suitable for the lead 101 with different specifications, so that the fixing structure 100 with various specifications is not required to be arranged, the production and processing time of the fixing structure 100 is saved, and the cost of the transformer is reduced.

Specifically to the embodiment of fig. 2, the first direction is a left-right direction and the second direction is an up-down direction.

In the embodiment of the present invention, two ends of each connecting unit 20 in the first direction are respectively connected to two fixing members 10, and the connecting position between at least one of the two fixing members 10 and each connecting unit 20 is adjustable in the first direction. Thus, by adjusting the connection position of the fixing member 10 with respect to the connection unit 20, the two fixing members 10 can be controlled to approach each other until the two fixing members 10 clamp the lead 101.

In some embodiments, each connecting unit 20 includes a connecting body 21 and a locking member 22, two ends of the connecting body 21 in the first direction are respectively connected to two fixing members 10, a connecting position of at least one of the two fixing members 10 and each connecting body 21 is adjustable in the first direction, and the locking member 22 is used for fixing the connecting position of the fixing member 10 and the connecting body 21 to ensure a fixing effect on a wire.

Wherein, when the connection position of only one fixing member 10 with each connecting body 21 is adjustable in the first direction, each connecting unit 20 includes one locking member 22. Specifically, one of the fixing members 10 is provided with two connecting holes 11, and two connecting bodies 21 of the two connecting units 20 are respectively inserted into the two connecting holes 11 and fixedly connected to the other fixing member 10. In this way, one of the fixing pieces 10 can be moved on the two connecting bodies 21 through the connecting hole 11 so as to be close to and away from the other fixing piece 10.

Further, the locking member 22 of each connecting unit 20 is threadedly connected to the connecting body 21, and the locking member 22 of each connecting unit 20 is located on the side of the fixing member 10 having the connecting hole 11, which is away from the other fixing member 10, so that when the two locking members 22 are rotated, the locking members 22 move on the connecting body 21 and gradually get close to or get away from the fixing member 10. When the lead 101 needs to be clamped, the two locking members 22 can be rotated to gradually approach the fixing member 10 having the connecting hole 11 until the two locking members 22 abut against the fixing member 10, and then the two locking members 22 are rotated continuously, so that the fixing member 10 can be driven to continuously move along the first direction and gradually approach another fixing member 10, because the other fixing member 10 is stationary, the distance between the two fixing members 10 can be gradually reduced until the lead 101 is clamped, and the fixing of the lead 101 is completed.

In other embodiments, it is also possible to make the connection position of each fixing member 10 with each connecting body 21 adjustable in the first direction to increase the adjustment range of the size of the fixing space 102. In this embodiment, each connecting unit 20 includes two locking members 22, and the two locking members 22 are respectively mounted on two ends of the connecting body 21 in the first direction. Furthermore, each fixing member 10 is provided with two connecting holes 11, and two ends of each connecting body 21 in the first direction respectively penetrate through one of the connecting holes 11 of each fixing member 10. Each locking element 22 is screwed to the currently present connecting body 21 and is located at an end of one of the fastening elements 10 facing away from the other fastening element 10.

When the lead 101 needs to be clamped, the two locking members 22 of the two connecting units 20 on one side of one of the fixing members 10 can be rotated to drive the fixing member 10 to approach the other fixing member 10 through the two locking members 22, and after the fixing member 10 is adjusted in position, the two locking members 22 of the two connecting units on one side of the other fixing member 10 can be rotated until the other fixing member 10 is adjusted in position, and the lead 101 is clamped between the two fixing members 10.

Optionally, the locking member 22 is a double nut, the connecting body 21 is an insulating screw, one of the nuts is a thick insulating nut 23, and the other nut is a thin insulating nut 24. Locking piece 22 and connecting body 21 all adopt insulating material to make to avoid the electric leakage risk.

In the embodiment of the present invention, in order to further reduce the risk of the leakage of the lead 101, the two fixing members 10 are also made of insulating material, which can be wood.

In the embodiment of the present invention, the fixing structure 100 further includes an insulating member 30, and the insulating member 30 is installed between the lead wire 101 and each of the connection units 20. In actual use, after the lead 101 is clamped by the two fixing members 10, there is a certain gap between the lead 101 and the two connecting units 20, and the gap can affect the clamping effect of the lead 101. For this reason, the gap between the connection unit 20 and the lead 101 may be filled with the insulating member 30, the fixing effect of the fixing structure 100 to the lead 101 may be improved, and the insulating effect between the connection unit 20 and the lead 101 may also be improved by the insulating member 30.

In some embodiments, to facilitate the installation of the insulating member 30, the insulating member 30 is constructed in a hollow structure so that the insulating member 30 can be fitted over the connection unit 20. Specifically, the portion of each connection unit 20 located in the fixing space 102 is sleeved with the insulating member 30, so that the gap between the connection unit 20 and the lead 101 is filled with the insulating member 30, and the insulating effect between the connection unit 20 and the lead 101 is improved.

The embodiment of the present invention provides that the fixing structure 100 further includes an insulating tube 31, the insulating tube 31 is disposed in the fixing space 102, and the lead 101 is sleeved with the insulating tube 31. In this way, the lead 101 is fixed by the insulating tube 31, and then the insulating tube 31 is clamped by the two fixing members 10, so that the length of the lead 101 can be increased, and the lead 101 is more concise and beautiful after being fixed.
