Description

Technical Field

[0001] This utility model relates to a high-stability relay base gasket, and more specifically, it relates to a high-stability relay base gasket that reliably connects internal parts of the relay base by screw locking. Background Technology

[0002] A relay is an electronic device used in automatic control circuits. The function of a relay is determined by its special internal structure. When a relay performs automatic control, the internal control components will repeatedly come into contact and collide. A gasket is a buffer component placed between the control components, which plays an important role in improving the stability of the internal structure and protecting the components.

[0003] Currently, relay bases on the market generally do not have specially designed washers or use washers with poor performance. With the development of related equipment, the requirements for the torque of relay base screws are getting higher and higher. Traditional washer structures may cause the nut to rotate due to insufficient screw torque, making it easy to slip during installation and use. Common washers cannot be fixed to the bottom parts. Considering that the frequency of collisions between parts of the relay base is high during normal operation, misalignment is likely to occur after a period of use, and considerable wear will also occur. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a relay base gasket with high stability, which can reliably connect the internal parts of the relay base by screw locking.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gasket for a high-stability relay base, comprising a gasket body, characterized in that the gasket body is provided with a threaded hole penetrating the gasket body, and the gasket body further comprises concave members symmetrically arranged on both sides of the gasket, each of the two concave members being provided with a pair of fixing feet.

[0006] By adopting the above technical solution, the threaded hole is used for bolt connection between the gasket and the upper contact parts of the high-stability relay base, which restricts the movement space of the upper contact parts and prevents large displacement between the parts when the relay is operating. At the same time, two fixing feet are provided at each end of the gasket body, which strengthens the friction between the gasket body and the lower contact parts, reduces the impact force between the gasket body and the parts, and improves the overall internal stability and durability.

[0007] The present invention is further configured such that: the ratio of the distance between the fixing feet on the same side to the width of the gasket body is between 1 / 3 and 1 / 2; the width of the fixing feet is configured such that: the width of the upper half is a fixed value, and the ratio of the width of the upper half to the width of the gasket body is between 1 / 4 and 1 / 3; the width of the lower half gradually decreases from top to bottom, and the minimum width of the lower half is 5 / 6 of the width of the upper half, and the maximum width of the lower half is equal to the width of the upper half.

[0008] By adopting the above technical solution, the width of the fixing foot is within a certain range, and the bottom adopts a chamfer structure with gradually decreasing width to ensure the strength of the fixing foot to a certain extent, while making it easy to connect the fixing foot to the parts below it.

[0009] The present invention is further configured such that the fixing foot is made of a rigid material.

[0010] By adopting the above technical solution, the fixing foot is more reliable and durable in terms of material, and the fixing foot is less likely to be misaligned with nearby components when a collision occurs.

[0011] The present invention is further configured such that: the top of the gasket for the high-stability relay base is provided with a circular groove for accommodating the bolt head, and the radius of the circular groove is larger than the radius of the threaded hole.

[0012] By adopting the above technical solution, the circular groove facilitates the screw to enter the threaded hole, and the circular groove can also guide the nut when using threads for connection.

[0013] The present invention is further configured such that the upper part of the concave member away from the gasket body is rounded.

[0014] By adopting the above technical solution, the rounded corner treatment on the concave part can make it less likely to hurt hands when assembling the locking washer, and the rounded corner treatment also makes the installation more time-saving and labor-saving. Attached Figure Description

[0018] Reference Figures 1 to 2The embodiment of the high-stability relay base gasket of this utility model is further described below.

[0019] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0020] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0021] A high-stability relay base gasket includes a gasket body 1. The gasket body 1 has a threaded hole 2 penetrating through it. The gasket body 1 also includes concave parts 3 symmetrically arranged on both sides of the gasket, each concave part 3 having a pair of fixing feet 4. By adopting the above technical solution, the threaded hole 2 is used for bolting the high-stability relay base gasket to the components in contact with the upper part of the gasket, limiting the movement space of the upper contact components and preventing large displacements between components during relay base operation. Simultaneously, the two fixing feet 4 at each end of the gasket body 1 enhance the friction between the gasket body 1 and the lower contact components, reducing the overall impact force between the gasket body 1 and the components, and improving the overall internal stability and durability.

[0022] Furthermore, the ratio of the distance between the fixing feet 4 on the same side to the width of the gasket body 1 is between 1 / 3 and 1 / 2. The width of the fixing feet 4 is set as follows: the width of the upper half is a fixed value, and the ratio of its width to the width of the gasket body 1 is between 1 / 4 and 1 / 3; the width of the lower half gradually decreases from top to bottom, and the minimum width of the lower half is 5 / 6 of the width of the upper half, while the maximum width of the lower half is equal to the width of the upper half. By adopting the above technical solution, the width of the fixing feet 4 adopts a certain range of values, and the bottom adopts a chamfered structure with a gradually decreasing width to a certain extent, which ensures the strength of the fixing feet 4. At the same time, it allows the fixing feet 4 to be easily connected to the parts below them. The distance between the fixing feet on the same side is greater than or equal to 1.2mm; otherwise, it would be impossible to fold the fixing feet and the gasket into a 90-degree structure.

[0023] Furthermore, the fixing foot 4 is made of a rigid material. By adopting the above technical solution, the fixing foot 4 is more reliable and durable in terms of material, and it is not easy for the fixing foot 4 to become misaligned with nearby components in the event of a collision.

[0024] Furthermore, the top of the gasket for the high-stability relay base is provided with a circular groove 5 for accommodating the bolt head, the radius of which is larger than the radius of the threaded hole 2. By adopting the above technical solution, the circular groove 5 facilitates the screw entering the threaded hole 2. When using threads for connection, the circular groove 5 can also guide the nut. When the downward extension depth of the circular groove 5 is less than 2mm, the thread engagement length is too low, and the connection strength will be poor. When the downward extension depth of the circular groove 5 is greater than 3mm, the space inside the mounting assembly will be smaller, which is not conducive to heat dissipation during equipment operation. Therefore, the downward extension depth of the circular groove 5 is greater than or equal to 2mm and less than or equal to 3mm, which makes the gasket more firmly fixed in the corresponding position inside the relay base, preventing it from loosening due to vibration and other factors during equipment operation, and also has a certain heat dissipation effect, which can improve the working reliability and service life of the relay base.

[0025] Furthermore, the portion of the upper end of the concave member 3 away from the gasket body 1 is rounded. By adopting the above technical solution, the rounded corners on the concave member 3 make it less likely to injure hands when assembling the locking gasket, and the rounded corners also make installation more time-saving and labor-saving.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
