In the prior art, the relay needs to be powered by the coil, and the armature generates attraction to make the moving contact of the relay swing to control the on and off of the isolation circuit. Sometimes, in the absence of electricity, it is necessary to detect whether the circuit is reasonable and whether the circuit is connected or disconnected. However, the relays in the prior art cannot achieve this and cannot detect whether the circuit is connected incorrectly and cause losses. Utility Model Content

[0006] As a preferred technical solution of the utility model: the first connecting part includes a pin installed on the moving contact and the static contact, and the second connecting part includes a socket matched with the pin.

[0007] As a preferred technical solution of the utility model: the bottom of the movable contact and the bottom of the static contact are both provided with conductive columns, and the conductive columns are adaptively connected to the conductive holes provided on the second connecting part.

[0008] As a preferred technical solution of the utility model: a through hole is further provided on the second connecting portion, and the through hole is used to facilitate the separation of the plug from the socket.

[0009] As a preferred technical solution of the utility model: the number of the plugs is two, and the two plugs are symmetrically arranged on both sides of the conductive column.

[0010] By adopting the above technical solution, the utility model has the following beneficial effects: since the window is arranged on the protective cover, it is convenient for the user to inspect and test the moving contact piece assembly and the static contact piece assembly, especially, in the absence of electricity, the moving contact piece assembly and the static contact piece assembly are manually controlled to contact or separate, so as to first detect whether the circuit is connected or disconnected, so as to avoid losses caused by wrong connection of the circuit. Based on this, although the solution has a simple structure, it does not affect the main structure and volume of the relay, and does not cause excessive increase in the use and production costs of the relay.

[0017] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0018] See also Figure 1-5The utility model provides an embodiment: a relay that is easy to detect, including a relay core 1; a protective cover 2 is sleeved on the outside of the relay core 1; a window 4 is provided on the protective cover 2, and a moving contact piece assembly 5 and a stationary contact piece assembly 6 installed on the relay core 1 are provided directly below the window 4; the window 4 is movably connected to a cover plate 3, and the cover plate 3 is covered on the window 4 to cover the moving contact piece assembly 5 and the stationary contact piece assembly 6 in the protective cover 2.

[0019] In summary, since the window 4 is provided on the protective cover 2, it is convenient for the user to inspect and test the moving contact assembly 5 and the stationary contact assembly 6. In particular, when there is no electricity, the moving contact assembly 5 and the stationary contact assembly 6 are manually controlled to contact or separate, so as to first detect whether the circuit is connected or disconnected, so as to avoid losses caused by wrong connection of the circuit. Based on this, although the structure of the scheme is simple, the simple structure does not affect the main structure and volume of the relay, and does not cause excessive increase in the use and production costs of the relay.

[0020] Furthermore, since the movable contact assembly 5 includes a movable contact plate 50 and a movable contact 51; the stationary contact assembly 6 includes a stationary contact plate 60 and a stationary contact 61; the movable contact 51 and the stationary contact 61 are both provided with a first connection portion 55, and the movable contact plate 50 and the stationary contact plate 60 are both provided with a second connection portion 59. Therefore, the stationary contact plate 60 and the stationary contact 61 are convenient to disassemble and assemble, and it is convenient to remove the stationary contact 61. Similarly, the movable contact plate 50 and the movable contact 51 are also simple and convenient to disassemble and assemble. After the contact 52 is ablated, the stationary contact 61 and the movable contact 51 can be replaced as a whole, so as to solve the problem that the existing relay needs to be replaced as a whole once the ring is damaged.

[0021] Specifically, since the first connecting portion 55 includes the pin 53 installed on the moving contact 51 and the stationary contact 61, and the second connecting portion 59 includes the socket 56 compatible with the pin 53, the assembly of the moving contact piece assembly 5 and the stationary contact piece assembly 6 is simple and convenient, and after assembly, with the cooperation of the socket 56 and the pin 53, the stability of the connection between the stationary contact 61 and the stationary contact plate 60 can be guaranteed, and similarly, the stability of the moving contact plate 50 and the moving contact 51 after connection can also be guaranteed.

[0022] Furthermore, since the bottoms of the movable contact 51 and the stationary contact 61 are both provided with conductive posts 54, and the conductive posts 54 are matched and connected with the conductive holes 58 provided on the second connecting portion 59, the movable contact 51 and the movable contact plate 50 can be connected with reliable conductivity by using the cooperation of the conductive posts 54 and the conductive holes 58, and the plug 53 can also be made of a thinner metal sheet or plastic sheet. Similarly, the stationary contact 61 and the stationary contact plate 60 also have reliable conductivity.

[0023] In addition, since a through hole 57 is provided on the second connecting portion 59, and the plug 53 is separated from the socket 56 through the through hole 57, a screwdriver can be inserted into the through hole 57 to deform the plug 53 so as to separate the plug 53 from the socket 56, thereby allowing the plug 53 to be smoothly pulled out of the socket 56.

[0024] At the same time, since there are two pins 53 and the two pins 53 are symmetrically arranged on both sides of the conductive column 54, the connection between the moving contact 51 and the moving contact plate 50 is more stable and reliable, so as to ensure the conductivity and stability of the moving contact piece assembly 5 and the stationary contact piece assembly 6.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
