[0022] Schematic diagram of the plate structure used for relays

[0023] refer to Figures 1 to 3 According to a preferred embodiment of the present invention, a plate structure for a relay, it should be noted that the structure of the plate structure for the relay is as follows Figure 2 As shown, it should be noted that this product is used to match the housing 10 of an external relay. Those skilled in the art should understand that the housing 10 has an opening and a cavity, the opening is connected to the cavity, and the product is set at the opening to seal the cavity. Figure 3 The internal components of the relay shown have a frame 20, which is arranged horizontally and installed on a side of the product close to the cavity.

[0024] Specifically, the plate structure for the relay further includes a connecting plate body 30, and the external skeleton 20 is arranged on the connecting plate body 30. The connecting plate body 30 has a positioning protrusion 31 on one side close to the cavity, and its arrangement is as follows Figure 1 As shown, the positioning protrusion 31 is used to define the position of the frame 20. Figure 3The front end 21 and rear end 22 of the skeleton 20 are shown, and the side of the rear end 22 close to the front end can abut against the side wall of the positioning protrusion 31, thereby limiting the installation position of the skeleton 20 to facilitate the subsequent installation of other components of the relay.

[0025] It should be noted that the connecting plate body 30 has a ventilation cavity 303 on one side close to the cavity. Specifically, Figure 3 The position shown, that is, those skilled in the art should understand that this is the structure of the moving reed and the static reed. When the moving contact and the static contact are disconnected, a high-temperature arc will be generated, and then high-temperature metal vapor will be generated. Therefore, this part of the airflow needs to be drained to reduce the degree of corrosion of the components near this place, thereby increasing the service life of the product. In addition, the design of the structure here can effectively reduce the materials used in the manufacture of the connecting plate body 30, thereby reducing the manufacturing cost of the connecting plate body 30.

[0026] In addition, the connecting plate body 30 is provided with a stop column 32 on one side of the positioning protrusion 31. The stop column 32 is arranged opposite to the positioning protrusion 31 and is spaced a predetermined distance apart. The stop column 32 is also staggered with the positioning protrusion 31, and the function of the stop column 32 is consistent with that of the positioning protrusion 31, that is, it is used to limit the position of the above-mentioned skeleton 20 to facilitate the subsequent installation of other accessories.

[0027] Specifically, the connecting plate body 30 further has a stopper 33 on a side close to the cavity. The stopper 33 is M-shaped and is located on a side of the stop post 32 away from the positioning protrusion 31 .

[0028] Specifically, the block 33 and the connecting plate body 30 together form a first positioning notch 100 and a second positioning notch 200. In addition, the connecting plate body 30 also has a first pin slot 301 and a second pin slot 302. The first pin slot 301 and the second pin slot 302 are arranged opposite to each other and are separated by a predetermined distance. In addition, the first pin slot 301 is opposite to the first positioning notch 100, and the second pin slot 302 is opposite to the second positioning notch 200. Figure 3 The two pins shown pass through the skeleton 20 and respectively cooperate with the first positioning notch 100 and the second positioning notch 200. In addition, the bottom of the skeleton 20 and the side facing the stop block 33 have a matching groove that cooperates with the stop block 33, that is, the position of the skeleton 20 is further limited by the connection between the stop block 33 and the matching groove.

[0029] It should be noted that the connecting plate body 30 also has a third pin slot 304, which is located on the side of the baffle 33 away from the first pin slot 301, and the third pin slot 304, the first pin slot 301 and the second pin slot 302 are arranged in a triangle. Specifically, Figure 3 As shown, the third pin slot is configured to cooperate with the yoke leg of the external relay, and the provision of the baffle 33 can increase the creepage distance between the yoke leg and the coil leg, thereby improving the insulation withstand voltage. It should also be noted that the height of the baffle 33 is less than the height of the baffle post 32.

[0030] In summary, the board structure for the relay according to the embodiment of the present application is explained, which provides the board structure for the relay with advantages such as good insulation and voltage resistance, simple structure, and reasonable layout.

[0031] It is worth mentioning that in the embodiments of the present application, the plate structure for the relay is simple, does not involve complex manufacturing processes and expensive materials, and is highly economical.
