The hook is in contact with the corner of the armature for a long time, which will cause damage to the corner of the armature. As the time the wall structure wraps the armature increases, the surface of the wall structure may be dented and damaged. However, it cannot be disassembled and replaced, so innovation is made in this technology. Utility Model Content

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4As shown, the abutment plate 10 is fixedly sleeved with one end of the screw rod 9, and the limiting top plate 11 is sleeved on one end of the screw rod 9, one side of one protective sleeve 14 is fixedly installed with an L-shaped plate 13, one side of the L-shaped plate 13 is fixedly connected to one side of the limiting top plate 11, and a plurality of extension strips 15 are fixedly installed between the inner walls of the two protective sleeves 14, and one side of the two protective sleeves 14 are respectively in contact with one side of the armature 4. The utility model provides a relay structure for preventing the armature from falling off, by providing a side abutment plate 6, a positioning strip 7, a nut 12 and an L-shaped plate 13, and the positioning strip 7 and the positioning hole 8 can be separated by rotating the two positioning strips 7 in the opposite direction, so that it is convenient to disassemble the protrusion 5 and the base 1 from each other, and a new side abutment plate 6 and protective sleeve 14 can be replaced.

[0027] Working principle: As one of the components on the circuit board, the relay has a wide range of applications, and many application scenarios are dynamic environments. The relay is mainly composed of a driving mechanism and a load mechanism, which are respectively fixed on the base 1, connected and pushed by the armature 4, so that the load end can realize the on-off function. The armature 4 is an important part connecting the driving mechanism and the load mechanism. It transmits the driving force through reciprocating motion and acts on the load end. In order to avoid the armature 4 from being separated from the base 1 and affecting the normal operation of the subsequent relay, the staff can embed the two protrusions 5 into the top of the base 1, and embed one end of the two positioning strips 7 into the inside of the two positioning holes 8 respectively. The two are threadedly connected, and then the protrusions 5 and the base 1 can be limited and fixed, which ensures the firmness of the side abutment plate 6. The material of the outer surface of the side abutment plate 6 is silicone, which is relatively soft. The silicone part contacts the side of the armature 4, and one side of the side abutment plate 6 abuts against one side of the armature 4. Subsequently, the limiting top plate 11 is sleeved on one end of the screw 9. The limiting top plate The bottom of 11 is abutted by the abutment plate 10, so that the limit top plate 11 is kept in a specific position and will not move downward at will. The nut 12 is threadedly sleeved on one end of the screw rod 9. After the limit top plate 11 is limited, the two protective sleeves 14 are also limited. The limit top plate 11 and the top of the armature 4 abut against each other. The two protective sleeves 14 can abut against the corners of the armature 4. The three cooperate with each other and can wrap the periphery of the armature 4 at the same time. The protective sleeve 14 can protect the corners of the armature 4 and prevent the armature 4 from falling off. At the same time, it can also cover the corners of the armature 4, thereby extending the service life of the armature 4. By rotating the two positioning bars 7 in the opposite direction, the positioning bar 7 and the positioning hole 8 can be separated, so it is convenient to separate the protrusion 5 and the base 1 from each other, and a new side abutment plate 6 and a protective sleeve 14 can be replaced. The two protective sleeves 14 are connected by a plurality of extension bars 15. The protective sleeve 14 and the limiting top plate 11 that are in contact with the surface of the armature 4 are partially made of rubber, which is relatively soft, thereby reducing the extrusion force between the two and the surface of the armature 4.
