Description

Technical Field

[0001] The utility model relates to the technical field of circuit control, in particular to a relay upper cover which can prevent deformation. Background Art

[0002] A relay is an electrical control device, usually used in automated control circuits. It is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] Publication (Announcement) No.: CN219575509U discloses a network relay housing with a protective structure, including a bottom shell, a top cover on the top of the bottom shell, four prompt components inside the bottom shell, two buffer components 1 are embedded on both sides of the bottom shell, and two buffer components 2 are embedded on the front and back of the bottom shell. The bottom shell and the top cover of this relay housing are connected through mounting holes and bolts and other hole mounting components. Although this connection method can ensure the connection stability of the two, it will affect the sealing and cause pollutants such as water vapor and dust to enter the interior of the relay. In order to solve this problem, the method of glue filling is used instead. However, when filling the glue, the entire housing, that is, the bottom shell and the top cover, need to be heated. However, the top cover in this document lacks any structural protection to prevent deformation, which will cause it to deform due to heat, thereby affecting the product qualification rate and product service life of the entire relay.

[0006] Further improvement: The first reinforcing rib assembly includes an integrally formed connecting reinforcing rib, two long-axis reinforcing ribs, and two short-axis reinforcing ribs.

The long-axis reinforcing rib acts on the long-axis side of the upper cover body and is connected to the corresponding connecting side of the vertical section, and the short-axis reinforcing rib acts on the short-axis side of the upper cover body and is connected to the corresponding connecting side of the horizontal section.

[0007] Further improvement: The vertical section and the horizontal section utilize their own widths to form several display areas on the upper end surface of the upper cover body.

[0014] Figure 2 is a schematic structural diagram of the lower part of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present utility model will be further described below with reference to the accompanying drawings:

[0016] Referring to the attached drawings: This deformation-preventable relay upper cover includes an upper cover body 1. On the upper end surface of the upper cover body 1, a first reinforcing rib assembly 2 is provided. The first reinforcing rib assembly 2 acts on both the long-axis sides and the short-axis sides of the upper cover body 1 simultaneously to prevent the outer sides of the long-axis sides and the outer sides of the short-axis sides of the upper cover body 1 from deforming inwardly and tilting to one side when the upper cover body 1 is affected by heating. On the lower end surface of the upper cover body 1, an inwardly recessed inner cavity 11 is provided, and a second reinforcing rib assembly 3 is arranged inside the inner cavity 11. The second reinforcing rib assembly 3 acts on the four corner positions of the inner cavity 11 simultaneously to prevent the corners of the upper cover body 1 from deforming inwardly and tilting to one side when the upper cover body 1 is affected by heating. The principle of the present utility model is that by providing the first reinforcing rib assembly 2 and the second reinforcing rib assembly 3 on the upper cover body 1, the overall structural strength of the upper cover body 1 is increased, and it also has the ability to resist deformation. The first reinforcing rib assembly 2 acts on the upper end surface of the upper cover body 1, and the main acting positions are on the long-axis sides and the short-axis sides of the upper cover body 1, which can prevent the outer sides of the long-axis sides and the outer sides of the short-axis sides from deforming inwardly and tilting to one side. The second reinforcing rib assembly 3 acts on the inside of the upper cover body 1 by means of the inner cavity 11, so that its main acting positions can be at the four corner positions of the inner cavity 11, that is, also aiming at the four corner positions of the upper cover body 1, which can prevent the corners from deforming inwardly and tilting to one side, thereby achieving full anti-deformation protection for the upper cover body 1 and effectively preventing the upper cover body 1 from deforming due to heat.

[0017] The first reinforcing rib assembly 2 includes integrally formed connecting reinforcing ribs 21, two long-axis reinforcing ribs 22, and two short-axis reinforcing ribs 23. The connecting reinforcing rib 21 is arranged at the central position of the upper cover body 1 and has a vertical section 21-a and a horizontal section 21-b. The long-axis reinforcing rib 22 acts on the long-axis side of the upper cover body 1 and is connected to the corresponding connecting side of the vertical section 21-a. The short-axis reinforcing rib 23 acts on the short-axis side of the upper cover body 1 and is connected to the corresponding connecting side of the horizontal section 21-b. The first reinforcing rib assembly 2 is arranged in such a way that its acting positions are on the long-axis side and the short-axis side of the upper cover body 1, that is, realized by the long-axis reinforcing rib 22 and the short-axis reinforcing rib 23. And the connecting reinforcing rib 21 is in a cross-shaped configuration, so that the structure of the middle position of the upper end surface of the upper cover body 1 can be strengthened and protected by the connecting reinforcing rib 21, and it can also be connected to the long-axis reinforcing rib 22 and the short-axis reinforcing rib 23. Thus, when the outer sides of the long-axis side and the short-axis side are deformed, an acting force to resist the deformation force can be generated by the configuration of the connecting reinforcing rib 21, thereby effectively preventing the upper cover body 1 from deforming due to heat.

[0018] The vertical section 21-a and the horizontal section 21-b utilize their own widths to form several display areas 4 on the upper end surface of the upper cover body 1. Such a setting allows components for display, such as product codes, to be arranged within the area 4.

[0019] The outer side surface of the long-axis reinforcing rib 22 is on the same level as the outer side surface of the long-axis side of the upper cover body 1, and the outer side surface of the short-axis reinforcing rib 23 is on the same level as the outer side surface of the short-axis side of the upper cover body 1. A buckle 5 that serves as a connecting component and is snap-fitted with the relay bottom shell is provided between the corresponding two side surfaces. Such a setting can reduce the influence of the buckle 5 on the outer side surfaces of the long-axis side and the short-axis side of the upper cover body 1. That is, after potting, since the upper cover body 1 is in the heat-receiving stage, but the bottom cover needs to be covered in time because the potting adhesive will harden immediately as it cools, the adhesion strength it exhibits will gradually decrease. The buckle 5 is snap-fitted with the slot on the bottom shell, but a pressing force will be exerted on the buckle 5 during the snap-fitting process. To reduce the influence of the pressing force on the outer side surfaces of the long-axis side and the short-axis side of the upper cover body 1, part of the buckle 5 is connected to the long-axis reinforcing rib 22 and the short-axis reinforcing rib 23.

[0020] The second reinforcing rib assembly 3 includes a first inclined reinforcing rib 31 and a second inclined reinforcing rib 32 that are cross-arranged. The first inclined reinforcing rib 31 and the second inclined reinforcing rib 32 act on the corners of the inner cavity 11. Such a setting of the second reinforcing rib assembly 3 satisfies the simultaneous action on the four corner positions of the inner cavity 11, and the cross-arrangement of the first inclined reinforcing rib 31 and the second inclined reinforcing rib 32 presents an X-shaped configuration, so that the acting range of the second reinforcing rib assembly 3 is expanded, thereby improving the anti-deformation ability and effectively preventing the upper cover body 1 from deforming due to heat.

[0021] A protrusion 12 that extends downward and has a configuration matching that of the inner cavity 11 is provided on the lower end surface of the upper cover body 1. A potting filling area 6 with a stepped configuration is formed between the protrusion 12 and the lower end surface of the upper cover body 1. After the upper cover and the bottom shell are assembled, only the outer side surface of the upper cover body 1 is in contact with the inner side surface of the bottom shell, while the outer side surface of the protrusion 12 cannot be in contact with the inner side surface of the bottom shell due to size reasons, thus creating a gap (i.e., the potting filling area 6). In this way, after potting, the area where the potting adhesive is located is not only between the outer side surface of the upper cover body 1 and the inner side surface of the bottom shell, but also in the gap between the outer side surface of the protrusion 12 and the inner side surface of the bottom shell, thereby increasing the filling amount and making the connection between the upper cover body 1 and the bottom shell firm.

[0022] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
