The edge of the casing 100 is provided with a connecting hole 110, the reinforcing ring 200 is inserted into the connecting hole 110, the reinforcing part 210 abuts against the edge of the casing 100 at the connecting hole 110, and the casing 100 is connected with the reinforcing ring 200 in an interference fit manner. The thickness at the edge of the case 100 is less than the height of the reinforcing ring 200.

According to the housing installation structure 10 of the relay, the structural strength of the housing 100 is improved through the reinforcing ring 200, and the relay is fixed on an installed object by inserting the screws into the reinforcing ring 200, so that the housing 100 of the relay is prevented from being crushed and cracked when the screws are installed. The installation stability of the reinforcing ring 200 in the connection hole 110 is improved by the reinforcing part 210, and after the external screw is installed, the reinforcing part 210 cooperates with the external screw to generate clamping force on the housing 100, thereby improving the installation strength. In addition, the reinforcing ring 200 also improves the assembly efficiency, the assembly of the reinforcing ring 200 and the shell 100 is simple, auxiliary equipment is not required, the assembly work can be completed manually, and meanwhile, the automatic production is convenient to realize. When the reinforcing portion 210 abuts against the end face of the housing 100, the assembling work is completed. The judgment standard of the assembly work completion degree is provided, and the quality inspection personnel can conveniently judge the assembly yield of the product.

The case 100 is a housing of the relay, and the relay is fixed to a mounting object through the case 100. The edge of the housing 100 is opened with a connection hole 110, and the connection hole 110 is used for installing the reinforcing ring 200. In an embodiment, referring to fig. 3, the edge of the housing 100 is integrally provided with a connecting block 120, and the middle region of the connecting block 120 is provided with the connecting hole 110. Preferably, the edge inside the connecting block 120 is further provided with a reinforcing rib 121, and the reinforcing rib 121 is further connected with the housing 100, that is, the housing 100 is integrally provided with the connecting block 120 and the reinforcing rib 121. Thus, the technical effect of improving the structural strength of the housing 100 can be achieved through the connecting blocks 120 and the reinforcing ribs 121.

The reinforcing ring 200 is used to reinforce the structural strength of the housing 100 and prevent the housing 100 from being crushed and cracked by screws during installation. The reinforcing part 210 is used to improve the installation stability of the reinforcing ring 200 in the connection hole 110, and after the external screw is installed, the reinforcing part 210 will form a clamping force on the housing 100, thereby improving the installation strength. The reinforcing ring 200 is interference-fitted to the housing 100 in the coupling hole 110, thereby improving coupling stability and assembling convenience. The thickness at the edge of the case 100 is less than the height of the reinforcing ring 200. Thus, in the installation process, the screw directly acts on the reinforcing ring 200, the shell 100 cannot be crushed, and the protection effect on the shell 100 is improved.

In order to further improve the connection stability between the casing 100 and the reinforcing ring 200, in one embodiment, the casing 100 is provided with a reinforcing groove 111 at the opening of the connection hole 110, the reinforcing groove 111 is matched with the reinforcing portion 210, the reinforcing portion 210 abuts against the casing 100 at the bottom of the reinforcing groove 111, and the outer side wall of the reinforcing portion 210 abuts against the groove wall of the casing 100 at the reinforcing groove 111. In this way, the reinforcing groove 111 serves to fasten the reinforcing part 210, thereby making the connection of the reinforcing ring 200 to the case 100 more stable. Thus, the connection stability of the housing 100 and the reinforcing ring 200 is improved, and the structural strength of the housing installation structure of the relay is improved.

To further avoid the housing 100 from being crushed and cracked by external screws during installation, in one embodiment, the depth of the reinforcement groove 111 is less than the thickness of the reinforcement portion 210. That is, the reinforcing part 210 is partially exposed and protrudes from the edge end surface of the connection hole 110 of the case 100. Thus, during the installation process of the external screw, the shell 100 and the object to be installed are prevented from being squeezed, and the structure of the shell 100 is further protected. Further, in an embodiment, an end portion of the reinforcing ring 200 away from the reinforcing portion 210 is exposed to the connecting hole 110. Thus, the external screw is only in contact with the reinforcing ring 200 and does not directly act on the shell 100, thereby enhancing the protection effect on the structure of the shell 100 and ensuring the structural integrity of the shell 100. It should be noted that, in another embodiment, the depth of the reinforcing groove 111 may be equal to the thickness of the reinforcing portion 210 to ensure the flatness requirement of the casing 100. So, promoted the reliability of this relay's casing mounting structure. In one embodiment, the reinforcement portion 210 is located at the bottom of the housing 100 at the edge. That is, the bottom of the housing 100 is seated on the surface of the mounted object. Screws or bolts are inserted into the reinforcing ring 200 from the top at the edge of the housing 100, thereby fixing the housing 100 to the surface of the object to be mounted. The reinforcing ring 200 reinforces the structural strength of the housing 100, and the reinforcing part 210 and the screw clamp the housing 100 together, thereby further improving the connection stability between the housing 100 and the reinforcing ring 200. In addition, the reinforcing part 210 also plays a role of dispersing pressure, reducing the pressure of the screw on the reinforcing ring 200, and improving the durability of the reinforcing ring 200. To increase the applicability, in one embodiment, the reinforcement 210 is located at the top of the edge of the housing 100. Thus, the housing 100 is reversely installed, and the top of the housing 100 may be seated on the surface of the installed object. It should be noted that the screw or the screw may be inserted from an end of the reinforcing ring 200 adjacent to the reinforcing portion 210, or may be inserted from an end of the reinforcing ring 200 away from the reinforcing portion 210. The reinforcing part 210 functions to disperse the pressure when a screw or a screw is inserted from the reinforcing ring 200 at an end adjacent to the reinforcing part 210. When a screw or a bolt is inserted from the end of the reinforcing ring 200 away from the reinforcing portion 210, the reinforcing portion 210 not only serves to disperse the pressure, but also serves to clamp the housing 100 together with the screw.

In one embodiment, the reinforcement portion 210 is circular. I.e. the stiffening channel 111 is a cylindrical channel, the stiffening channel 111 is adapted to the stiffening portion 210. The reinforcing part 210 is in a ring shape, so that the reinforcing ring 200 is easy to manufacture, the forming process is simple, and the production cost is reduced. In order to further improve the connection stability of the reinforcing ring 200 and the housing 100 and prevent the reinforcing ring 200 from rotating in the connection hole 110, in one embodiment, the reinforcing part 210 is polygonal. Specifically, in one embodiment, the reinforcing portion 210 is hexagonal. In another embodiment, the reinforcement portion 210 is a quadrangular prism. That is to say, the reinforcing groove 111 is matched with the reinforcing part 210, so that the edge of the reinforcing part 210 is in effective contact with the casing 100, the reinforcing groove 111 can limit the rotation of the reinforcing part 210, and the reinforcing groove 111 plays a limiting role. Thus, the reinforcing ring 200 is difficult to rotate in the connecting hole 110, so that the connecting stability of the housing 100 and the reinforcing ring 200 is further enhanced, and the mounting stability of the housing mounting structure of the relay is further improved.

In order to improve the structural strength of the reinforcing ring 200, in one embodiment, the material of the reinforcing ring 200 is carbon steel. Specifically, in one embodiment, the reinforcing ring 200 is carbon steel Q235. In another embodiment, the reinforcing ring 200 is carbon steel 10B 21. Thus, the reinforcing ring 200 has high structural strength, and the reinforcing ring 200 is not easily crushed and cracked. Further, in one embodiment, the material of the reinforcing ring 200 is a copper alloy. So, promoted the structural strength who adds ring 200, improved the casing mounting structure's of this relay job stabilization nature, promoted the durability, prolonged life, further strengthened installation stability.
