Embodiment
A kind of stepping motor end cap with safeguard function that the utility model embodiment provides, hermetically-sealed construction that can safeguard function in the stepping motor end cover designs, make motor when work, anti-sealing or other liquids and gases infiltrate motor internal from motor down-lead, thereby improve the degree of protection of motor, can make stepping motor work under rugged environment or the environment in high humility.Compare with the end cap of existing similar stepping motor, the utlity model has: advanced design, exclusion seal is simple and reasonable, reliable, the advantages such as good manufacturability.
The stepping motor end cap with safeguard function the utility model embodiment offered below in conjunction with accompanying drawing is described in detail.
As Fig. 1, 2, 3, shown in 4, a kind of stepping motor end cap with safeguard function that the utility model embodiment provides, it is characterized in that, comprise end cap 1, waterproof inner chamber 2, boss 3, power supply lead wire 4, anti-folding body 5, the side of described end cap 1 arranges boss 3, described waterproof inner chamber 2 is arranged at the centre of described end cap 1, be provided with sealing ring 6 in described waterproof inner chamber 2, described waterproof inner chamber 2 forms faying face 7 with described sealing ring 6, be provided with gap between described faying face 7 and described sealing ring 6, described power supply lead wire 4 is connected with described anti-folding body 5, be fixed in end cap 1 one sides.
Particularly, described waterproof inner chamber 2 is set to the bowl-like depression structure.
Particularly, marine glue can be placed in the gap between described faying face 7 and described sealing ring 6.
