Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal gaskets, and more particularly to a gasket used for fixing screws of a relay base. Background Art
[0002] Early relay bases may not have specially designed gaskets, or the gaskets used may be of poor quality, or they may use hexagonal or square nuts. With the development of electrical equipment, the torque requirements for relay base screws are becoming increasingly stringent. In traditional structures, insufficient torque can cause the nut to rotate, and the gasket may not be firmly fixed to the base, making it easy for the screw to slip during installation.
[0003] Specialized washers can effectively improve screw torque performance. Typically made of highly conductive metals such as copper and silver, or alloys, they reduce contact resistance and ensure stable current flow. Furthermore, mechanically, washers provide precise spacing control and stable support for the relay base's moving parts, preventing displacement due to vibration and other factors, thereby ensuring stable and reliable operation of the relay base. Utility Model Content
[0004] In view of the deficiencies in the prior art, the present invention aims to provide a firmly installed washer for fixing screws on a relay base.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a gasket for fixing screws on a relay base, comprising a gasket body, wherein a first folded angle and a second folded angle are symmetrically provided on both sides of the gasket body, the first folded angle is located in the middle of one side of the gasket body, a groove is provided at the bottom end of the second folded angle, the groove divides the bottom end of the second folded angle into symmetrically arranged pins, and a threaded hole is provided on the gasket body.
[0006] The present invention is further configured as follows: hook structures are provided on both sides of the first folded angle, and the width of the first folded angle is between 1 / 2 and 2 / 3 of the width of the gasket body.
[0007] The present invention is further configured such that: the width of the first folded angle is greater than the width of the groove.
[0008] The utility model is further configured such that: the depth of the threaded hole is greater than the thickness of the gasket body and less than the length of the first folded angle.
[0009] The utility model is further configured as follows: the gasket body is provided with a circular hole integrally connected with the threaded hole, and the diameter of the circular hole is larger than the inner diameter of the threaded hole and smaller than the outer diameter of the threaded hole.
[0010] The present invention is further configured as follows: the bottom end of the pin is provided with a chamfered structure for guiding insertion, and the width of the pin is between 1 / 4 and 1 / 3 of the width of the gasket body.
[0011] The beneficial effects of the utility model are:
[0012] 1. The gasket body is symmetrically provided with a first corner and a second corner on both sides. The first corner is located in the middle of one side of the gasket body. A groove is provided at the bottom end of the second corner. The groove divides the bottom end of the second corner into symmetrically arranged pins. The first corner and the second corner are triangular in structure when installed on the base, making the connection structure more firm and stable. A groove is formed between the two pins, which are placed on a suitable base to prevent movement and make installation more convenient. A threaded hole is provided on the gasket body for easy connection with a nut to tighten the wires.
[0013] 2. The first angle has hooks on both sides. When the first angle is installed on the base, it hooks into the inner wall of the mounting hole on the base, preventing the gasket from easily falling off. If the width of the first angle is less than 1 / 2 of the width of the gasket body, the structural strength of the first angle is reduced, making it susceptible to damage. If the width of the first angle is greater than 2 / 3 of the width of the gasket body, the thickness of the mounting groove on the base is reduced, reducing the strength of the connection between the two. Therefore, the width of the first angle is set between 1 / 2 and 2 / 3 of the width of the gasket body to ensure good structural strength between the first angle and the gasket body.
[0014] 3. The width of the first bend is greater than the width of the groove, ensuring structural strength on both sides of the gasket. The depth of the threaded hole is greater than the thickness of the gasket body and less than the length of the first bend. This prevents slippage due to insufficient connection strength when tightening the nut, which could affect the product's electrical connection and operating efficiency. The gasket body is equipped with a circular hole that is integrally connected to the threaded hole. The diameter of the circular hole is larger than the inner diameter of the threaded hole and smaller than the outer diameter of the threaded hole, allowing the nut to quickly locate the threaded hole for an efficient threaded connection.
[0015] 4. The bottom of the pin is equipped with a chamfered structure to guide insertion. When the gasket and base are installed, they can be quickly inserted into the mounting hole and tightly connected. When the width of the pin is less than 1 / 4 of the width of the gasket body, it is easily damaged by external pressure during installation. When the width of the pin is greater than 1 / 3 of the width of the body, the limiting gap between the two becomes smaller and cannot effectively serve the limiting function. Therefore, the width of the pin is set between 1 / 4 and 1 / 3 of the width of the gasket body, which does not affect the structural strength while saving production costs.

[0019] Reference Figures 1 to 2 The embodiments of the present invention are further described.
[0020] For ease of explanation, spatial relative terms such as "upper", "lower", "left", and "right" are used in the embodiments to illustrate the relationship between one element or feature shown in the figures and another element or feature. It should be understood that, in addition to the orientation 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 figure is inverted, the element described as being "under" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.
[0021] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.
[0022] like Figures 1 to 2 The gasket shown is used for fixing screws of a relay base, including a gasket body 1, wherein a first folded corner 3 and a second folded corner 9 are symmetrically provided on both sides of the gasket body 1, the first folded corner 3 is located in the middle of one side of the gasket body 1, and a groove 7 is provided at the bottom end of the second folded corner 9. The groove 7 divides the bottom end of the second folded corner 9 into symmetrically arranged pins 4. When the first folded corner 3 and the second folded corner 9 are installed on the base, they form a triangular structure, making the connection structure more firm and stable. A groove 7 is formed between the two pins 4, which are placed on a suitable base to prevent movement and make installation more convenient. A threaded hole 6 is provided on the gasket body 1 for convenient connection with a nut to tighten the wires.
[0023] The first folded corner 3 is provided with a hook structure 2 on both sides. When the first folded corner 3 is installed on the base, it hooks with the inner wall of the mounting hole on the base, preventing the gasket from falling off easily. When the width of the first folded corner 3 is less than 1 / 2 of the width of the gasket body 1, the structural strength of the first folded corner 3 is reduced and it is easy to damage. When the width of the first folded corner 3 is greater than 2 / 3 of the width of the gasket body 1, the thickness of the mounting groove on the base is reduced, which reduces the connection strength between the two. Therefore, the width of the first folded corner 3 is set to between 1 / 2 and 2 / 3 of the width of the gasket body 1, so that the first folded corner 3 and the gasket body 1 maintain good structural strength.
[0024] The depth of threaded hole 6 is greater than the thickness of gasket body 1 and less than the length of first bend 3, preventing slippage due to insufficient connection strength when tightening with the nut, which could affect the product's electrical connection and operating efficiency. Gasket body 1 is provided with a circular hole 8 integrally connected to threaded hole 6. The diameter of circular hole 8 is greater than the inner diameter of threaded hole 6 and smaller than the outer diameter of threaded hole 6, allowing the nut to be quickly positioned in threaded hole 6 for an efficient threaded connection.
[0025] The bottom end of the pin 4 is provided with a chamfered structure 5 to guide insertion. When the gasket and base are installed, they can be quickly inserted into the mounting hole and tightly connected. If the width of the pin 4 is less than 1 / 4 of the width of the gasket body 1, it is easily damaged by external pressure during installation. If the width of the pin 4 is greater than 1 / 3 of the width of the body, the limiting gap between the two becomes smaller, and the limiting function cannot be effectively performed. Therefore, the width of the pin 4 is set between 1 / 4 and 1 / 3 of the width of the gasket body 1, which does not affect the structural strength while saving production costs.
[0026] The folded angle forms a 90-degree structure with the gasket body 1, and the width from the groove to the gasket body on the same side is greater than or equal to 1.2 mm. Otherwise, it cannot be folded into a 90-degree structure, making the product easier to process during the manufacturing process, thereby improving the molding quality and production efficiency of the product. When the depth of the threaded hole 6 stretched downward is less than 2 mm, the engagement length of the thread is too low, and the connection strength deteriorates; when the depth of the threaded hole 6 stretched downward is greater than 3 mm, the space inside the installation component becomes smaller, which is not conducive to heat dissipation. Therefore, the depth of the threaded hole 6 stretched downward is greater than or equal to 2 mm and less than or equal to 3 mm, so that the gasket is more firmly fixed in the corresponding position inside the relay base, preventing loosening due to factors such as vibration during equipment operation, and having a certain heat dissipation effect, thereby improving the working reliability and service life of the relay base.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
