Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: a magnetic latching relay comprises a bottom shell 1, wherein a partition plate 11 is arranged in the bottom shell 1, and the interior of the bottom shell 1 is divided into a first installation cavity and a second installation cavity through the partition plate 11; an electromagnetic coil 3 is arranged in the first mounting cavity, and a movable contact piece 4, a first connecting piece 5 and a second connecting piece 6 are arranged in the second mounting cavity; a support plate 12 is further arranged in the second mounting area, the support plate 12 is attached to one side plate of the bottom shell 1, and one ends of the first connecting plate 5 and the second connecting plate 6 are fixed in the bottom shell 1 through a notch 13 formed in the support plate 12; and is connected with the upper end surface of the bottom shell 1 through the arranged cover plate 2 so as to cover the electromagnetic coil 3 and the other ends of the first connecting sheet 5 and the second connecting sheet 6 in the bottom shell 1.

In summary, the movable contact piece 4 and the two connecting pieces can be separated from each other due to the arrangement of the partition plate 11, so that the mutual influence of heat sources is reduced, and meanwhile, the two connecting pieces are connected with an external power line, so that the equipment does not need to be connected with the power line by using a braided copper wire; and the heat dissipation capacity of the two connecting pieces is improved so as to ensure the safety of the equipment during use. In summary, the utility model optimizes the structure of the existing relay to prolong the service life of the relay;

meanwhile, two connecting sheets are contacted with the movable contact spring, so that a large amount of copper braided wires can be saved, and the resistance of a current loop can be reduced; and thirdly, the space required by the installation of the connecting sheets is small, so that the overall structure of the relay is compact.

Furthermore, as the first connecting piece 5 is provided with the bolt 9, and the bolt 9 is in adaptive connection with the slot arranged on the movable contact piece 4, one end of the first connecting piece 5 can be stably connected with the movable contact piece 4, so as to ensure the stability of the two connected pieces.

Furthermore, since the first connecting piece 5 and the second connecting piece 6 are both provided with the connecting holes 7, the external power line is fixed on the two connecting pieces by connecting the connecting holes 7 with bolts; meanwhile, one surface, far away from the second connecting sheet 6, of the first connecting sheet 5 is also provided with a bending part 8, so that the structural strength of the first connecting sheet 5 can be enhanced by the bending part 8, and the installation deflection of an output end caused by the torsion progressive force of an installation screw is avoided.

On the basis of the above scheme, the movable contact piece 4 is provided with the interference part 18 and is connected with the electromagnetic coil 3 through the connecting groove 10 arranged on the interference part 18. The contact part 18 is a semicircular arc-shaped structure directly integrated with the movable contact piece 4, so that the movable contact piece 4 has elasticity and cannot be easily deformed, and particularly, the distance between the movable contact piece 4 and the partition plate 11 can be limited, so that the phenomenon of poor contact caused by large distance between the movable contact piece 4 and the second connecting piece 6 is avoided. In addition, the arc-shaped interference part 8 is convenient for airflow to flow so as to realize the cooling of the movable contact piece 4.

Specifically, the movable contact spring 4 comprises a first plate body 15, a second plate body 16 and a third plate body 17; wherein the first plate body 15 faces the partition plate 11 and the third plate body 17 faces the support plate 12, thereby making the movable contact 4 structurally strong.

Furthermore, bending plates 14 are arranged at the ends, facing the bottom shell 1, of the first connecting sheet 5 and the second connecting sheet 6, and a bolt 9 is also arranged on the bending plates 14. Therefore, two connecting pieces can be inserted into the bottom shell 1 so as to facilitate the contact area of the two connecting pieces and the bottom shell 1, and particularly, the first connecting piece 5 and the movable contact piece 4 are reliably connected by utilizing the pins 9 arranged on the two connecting pieces; and secondly, the second connecting piece 6 is reliably connected with the bottom shell 1, so that the phenomenon that the two connecting pieces are loosened when the movable contact piece 4 works is avoided.
