Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein identical from beginning to end
Or similar label represents same or similar element or the element with same or like function.Retouched below with reference to accompanying drawing
The embodiment stated is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
In the relay of correlation technique, due to no overload protection arrangement, in relay adhesive, once load current is excessive
Or circuit occurs short circuit and easily causes to sinter, and makes product loss of function, causes danger.In addition, there is no arc extinguishing in above-mentioned technology
Device, arc time length, product service life are short.In order at least solve the technical problem in correlation technique to a certain extent
One of, present applicant proposes a kind of relay, safety and stability are higher.
With reference to Fig. 1 to Fig. 5, relay 100 according to an embodiment of the invention, including：Casing 1, bottom plate 2 and drive
Dynamic device 4.
Specifically, stationary contact group 11 is provided with casing 1, stationary contact group 11 includes two stationary contacts 111 of mutually insulated.
Bottom plate 2 includes plate body 22, movable contact group 21 and arc extinguishing side plate 23, and movable contact group 21 is located on plate body 22, and dynamic tactile
Point group is 21 corresponding with stationary contact group 11, wherein, movable contact group 21 includes two movable contacts 211, and movable contact group 21
Mutually insulated between two movable contacts 211.
Arc extinguishing side plate 23 upwardly extends from plate body 22, and two movable contacts 211 of at least one movable contact group 21 are located at and gone out
The inner side of arc side plate 23 is simultaneously conducted by fuse 3.That is, two movable contacts of at least one movable contact group 21
211 are not only provided at the inner side of arc extinguishing side plate 23, but also are conducted by fuse 3.Preferably fuse 3 is located at bottom
On plate 2.
Bottom plate 2 is movably arranged between conduction position and open position in casing 1.As shown in Fig. 2 bottom plate 2 is being led
Movable contact group 21 contacts with stationary contact group 11 during logical position so that is conducted between two stationary contacts 111 of stationary contact group 11；
As shown in figure 1, bottom plate 2, in open position, movable contact group 21 separates with stationary contact group 11, make the two of stationary contact group 11
Individual stationary contact 111, which mutually disconnects, to be conducted.
Drive device 4 is connected with bottom plate 2 to drive bottom plate 2 to be moved between conduction position and open position.
Because plate body 22 is provided with arc extinguishing side plate 23, and two movable contacts 211 of at least one movable contact group 21 are located at arc extinguishing
The inner side of side plate 23 is simultaneously electrically connected by fuse 3, when bottom plate 2 is located at conduction position, due to the two of movable contact group 21
Individual movable contact 211 and two stationary contacts 111 of stationary contact group 11 are correspondingly connected, can be by fuse 3 by stationary contact
Two stationary contacts 111 of point group 11 electrically connect.
During the use of relay 100, if there is current overload or it is short-circuit the problems such as when, fuse 3 disconnects, from
And the electrical connection between two stationary contacts 111 of stationary contact group 11 is disconnected, relay 100 is off, from
And disconnecting circuit.
Relay 100 according to embodiments of the present invention, adds arc extinguishing side plate 23, relay is in conducting state and off-state
Between when changing, caused electric arc is divided into section, makes product excessive or electric arc caused by short circuit occurs for circuit in load current
Buffering is played a part of by arc-control device, can faster arc extinguishing.Due to being provided with fuse 3 in stationary contact 111,
The effect of overload protection and short-circuit protection is realized by fuse 3, to improve the circuit with the relay 100
The security of system, avoid fire etc. caused by excessively stream or short circuit.
