In the middle position of one end of the wiring board, a fastening sleeve is fixedly arranged. The fastening sleeve is tightly sleeved on the conductive rod to connect the conductive rod and the wiring board together. On the outer wall of the fastening sleeve, baffles are vertically and symmetrically fixedly arranged. An insertion port is formed between the baffles, and the insertion port is communicated with the inside of the fastening sleeve. A first clamping groove is horizontally opened at the middle position of the fastening sleeve and close to one side of the baffle. A second clamping groove is horizontally opened on the conductive rod. The positions of the first clamping groove and the second clamping groove correspond to each other, facilitating the quick insertion of a snap spring. A "U"-shaped snap spring is arranged in the first clamping groove and the second clamping groove. The shapes of the first clamping groove, the second clamping groove and the snap spring fit each other, ensuring that the snap spring is firmly and reliably inserted into the first clamping groove and the second clamping groove. The width a of the snap spring is the same as the distance b between the inner diameter of the first clamping groove and the outer diameter of the second clamping groove, which not only ensures the reliable connection between the snap spring and the conductive rod, but also ensures the limiting effect of the snap spring on the fastening sleeve, preventing the fastening sleeve from loosening and moving.

[0005] Preferably, a locking nut is arranged on the conductive rod close to the fastening sleeve.

[0006] Preferably, the first clamping groove, the second clamping groove and the snap spring have the same thickness, ensuring the tight and reliable connection between the conductive rod, the fastening sleeve and the snap spring, and preventing the fastening sleeve from loosening and moving.

[0007] Preferably, the central angles of the first clamping groove and the second clamping groove are the same and are both 230° - 250°, which not only ensures the stability of the connection structure of the fastening sleeve, but also ensures the stable and reliable connection between the conductive rod, the fastening sleeve and the snap spring.

[0008] The beneficial effects of the present utility model are as follows: The structure design of the present utility model is relatively novel. A first card slot is horizontally provided on the fastening sleeve, and a second card slot corresponding to the position of the first card slot is horizontally provided on the conductive rod, which is convenient for the snap ring to be quickly inserted. A snap ring is arranged in the first card slot and the second card slot, which not only ensures the reliable connection between the snap ring and the conductive rod, but also ensures the limiting effect of the snap ring on the fastening sleeve, preventing the fastening sleeve from loosening and moving, thus ensuring the stable and reliable contact and the normal use of the conductive rod, and being convenient for replacement at the same time.

[0015] In order to more clearly understand the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0016] Such as Figures 1-5A conveniently replaceable low-voltage conducting rod of a transformer, comprising a conducting rod 1. One end of the conducting rod 1 is provided with a wiring board 2 for connection to an external wire. At the middle position of one end of the wiring board 2, a fastening sleeve 3 is fixedly arranged. The fastening sleeve 3 is tightly sleeved on the conducting rod 1 to connect the conducting rod 1 and the wiring board 2 together. On the outer wall of the fastening sleeve 3, baffles 4 are fixedly arranged vertically and symmetrically. An insertion slot 5 is formed between the baffles 4, and the insertion slot 5 communicates with the inside of the fastening sleeve 3. A locking nut 9 is arranged on the conducting rod 1 near the fastening sleeve 3. At the middle position of the fastening sleeve 3 and on the side close to the baffle 4, a first clamping groove 6 is horizontally opened. A second clamping groove 7 is horizontally opened on the conducting rod 1. The positions of the first clamping groove 6 and the second clamping groove 7 correspond to each other, facilitating the quick insertion of a snap spring 8. The central angles of the arcs of the first clamping groove 6 and the second clamping groove 7 are the same and both are 240°, which not only ensures the stability of the connection structure of the fastening sleeve 3 but also ensures the stable and reliable connection of the conducting rod 1, the fastening sleeve 3, and the snap spring 8. A "U"-shaped snap spring 8 is arranged in the first clamping groove 6 and the second clamping groove 7. The shapes of the first clamping groove 6, the second clamping groove 7, and the snap spring 8 match each other to ensure that the snap spring 8 is firmly and reliably inserted into the first clamping groove 6 and the second clamping groove 7. The width a of the snap spring 8 is the same as the distance b between the inner diameter of the first clamping groove 6 and the outer diameter of the second clamping groove 7, which not only ensures the reliable connection between the snap spring 8 and the conducting rod 1 but also ensures the limiting effect of the snap spring 8 on the fastening sleeve 3 to prevent the fastening sleeve 3 from loosening and moving. The thicknesses of the first clamping groove 6, the second clamping groove 7, and the snap spring 8 are the same, ensuring the tight and reliable connection of the conducting rod 1, the fastening sleeve 3, and the snap spring 8 and preventing the fastening sleeve 3 from loosening and moving.
