The following detailed description is made with reference to the accompanying drawings and specific embodiments.
Please refer to fig. 1, fig. 2, fig. 3 and fig. 4 together, in which fig. 1 is a side view of an ultra-thin large current control relay provided in an embodiment of the present invention, fig. 2 is a side sectional view of the ultra-thin large current control relay provided in an embodiment of the present invention, fig. 3 is a top view of the ultra-thin large current control relay provided in an embodiment of the present invention, and fig. 4 is a top sectional view of the ultra-thin large current control relay provided in an embodiment of the present invention.
As shown in fig. 2 and 4, the ultra-thin large current control relay includes a housing 1, a base plate 2 and a relay body 3, wherein the relay body 3 is fixedly mounted on the base plate 2, and a ring of a surrounding plate 4 is provided on the base plate 2 around the relay body 3, and the surrounding plate 4 is fixedly provided on the base plate 2 and is integrally connected with the base plate 2. The housing 1 is buckled on the bottom plate 2, the coaming 4 plays a role of limiting the housing 1, the outer side wall of the coaming 4 is contacted with the inner side wall of the bottom of the housing 1, and the coaming 4 is limited in the housing 1.
Referring to fig. 1 and 3, the bottom plate 2 is symmetrically provided with locking shells 5 at two sides of the housing 1, the locking shells 5 are of a shell structure having a cavity, and the locking shells 5 are fixedly provided on the bottom plate 2 and are also integrally connected with the bottom plate 2.
With continued reference to fig. 2 and 4, a horizontally rotatable gear 6 is rotatably connected in the locking housing 5, and the gear 6 is rotatably connected with the top of the locking housing 5 and the upper part of the bottom plate 2 through a rotating shaft 13. Specifically, bearings 16 are fixedly embedded on the inner side of the top of the locking shell 5 and the upper part of the bottom plate 2 respectively, the rotating shaft 13 is coaxially and fixedly inserted on the gear 6, the upper end of the rotating shaft 13 is fixedly inserted in an inner ring of the bearing 16 on the inner side of the top of the locking shell 5, and the lower end of the rotating shaft 13 is fixedly inserted in an inner ring of the bearing 16 on the upper part of the bottom plate 2, so that the gear 6 can horizontally rotate.
In addition, a horizontally extending locking rod 8 and an unlocking rod 9 are respectively connected in each locking shell 5 through a spring 7, namely, a limiting through hole 14 for the locking rod 8 and the unlocking rod 9 to correspondingly extend is arranged on the locking shell 5, the locking rod 8 and the unlocking rod 9 extend from the corresponding limiting through hole 14, and one ends of the locking rod 8 and the unlocking rod 9, which do not extend out of the locking shell 5, are fixedly connected with the inside of the locking shell 5 through the spring 7. Meanwhile, racks 10 meshed with the gear 6 are respectively arranged on the locking rod 8 and the unlocking rod 9, and the racks 10 are correspondingly and fixedly embedded on the locking rod 8 and the unlocking rod 9.
