Description

Technical Field

[0001] This disclosure relates to a cage nut. Background Technology

[0002] Insert nuts have a wide range of applications, such as installation on cabinets, chassis, and controllers. An insert nut is typically a fastener consisting of a flexible outer shell and an inner nut. The outer shell positions the inner nut within it, while the inner nut provides the internal threads for assembly. Currently, insert nuts are usually inserted into pre-drilled holes using specialized tools and then secured to metal or other sheet metal using further simplification of installation and removal.

[0003] In addition, in order to compensate for the positional deviation between the mounting hole and the insert nut, a gap is usually left between the combination of the outer shell and the inner nut. However, this may cause unfavorable relative rotation between the inner nut and the outer shell, thus affecting the fastening effect. Summary of the Invention

[0004] The purpose of this disclosure is to provide an insert nut that is easy to install and remove and has a reliable connection.

[0005] According to one embodiment, an insertable nut is provided, the insertable nut comprising:

[0006] The nut body has a mounting hole with internal threads;

[0008] The housing has a connecting body, and a first arm and a second arm extending from opposite sides of the connecting body, the first arm and the second arm being opposite to each other and together with the connecting body forming a first space for accommodating the nut body.

[0009] According to one embodiment, the engaging body is provided with an engaging port, and the first end of the nut body has a non-circular shape that matches the engaging port so that it can be inserted into and fixed in the engaging port in a form fit. The second end of the nut body opposite to the first end is exposed to the outside for fasteners to be screwed into the mounting hole.

[0010] According to one embodiment, the first arm and the second arm extend substantially perpendicular to the engagement body and are capable of clamping and securing the nut body in the first space.

[0011] According to one embodiment, the free end of the first arm is provided with a first wing extending away from the first space, and the free end of the second arm is provided with a second wing extending away from the first space.

[0012] Both the first arm and the second arm are provided with a latching part, which protrudes outward from the surface of the first arm and the second arm opposite to the first space.

[0013] A second space is formed between the latching portion and the corresponding first wing, and between the latching portion and the corresponding second wing, respectively, for confining at least a portion of the carrier member within the second space.

[0014] According to one embodiment, the latching portions on the first arm and the latching portions on the second arm are arranged symmetrically with respect to the engaging body.

[0015] According to one embodiment, the housing is a one-piece component made from a single sheet metal.

[0016] The first arm and the second arm are respectively bent from opposite sides of the joining body in the same direction, substantially perpendicular to the joining body.

[0017] The first wing and the second wing are formed by bending from the free ends of the first arm and the second arm away from the connecting body, respectively, and substantially perpendicular to the first arm and the second arm.

[0018] According to one embodiment, the joining body of the housing is formed by stacking one portion of the plate onto another portion.

[0019] According to one embodiment, a through hole is provided at the bend between the first wing and the first arm, and / or at the bend between the second wing and the second arm.

[0020] According to one embodiment, the latching portion is obliquely conical and includes: a pressing surface extending outward from the outer surface of the wing at an acute angle toward the free end, and latching side surfaces located on both sides of the pressing surface.

[0021] According to one embodiment, the nut body includes a cylindrical portion located at its center and two side supports connected to opposite sides of the cylindrical portion.

[0022] The mounting hole is located at the longitudinal center of the cylindrical part.

[0023] The first end extends from the cylindrical portion toward the engagement port of the engagement body and has a smaller radial dimension than the cylindrical portion, thereby forming a stepped portion with the cylindrical portion so that when the nut body is fastened in the housing, the stepped portion presses against the periphery of the engagement port.

[0024] According to one embodiment, the nut body has a first side and a second side opposite to each other. The first side and the second side are respectively the surfaces of the two side supports that are away from the cylindrical portion, and are respectively sandwiched between the same side edges of the first arm and the second arm, so as to restrict the rotation of the nut body within the first space.

[0074] It should also be noted that many specific details are set forth in the following description to provide a full understanding of this disclosure. However, this disclosure may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this disclosure is not limited to the specific embodiments disclosed below. In the description of this disclosure, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the parts or components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0075] Furthermore, in this disclosure, the rightward direction in the left-right direction is defined as the positive X-direction, the forward direction in the front-back direction is defined as the positive Y-direction, the upward direction in the up-down direction is defined as the positive Z-direction, and the plane formed by the X and Y directions is defined as a horizontal plane. The directions described above are merely for the convenience of referring to the accompanying drawings and are not intended to limit the scope of this disclosure. In other words, based on variations in the placement orientation of the product of this disclosure, its left-right, front-back, and up-down directions may differ from the specific descriptions herein.

[0076] Please see Figures 1-2 The insert nut 100 according to this disclosure may include a nut body 110 and a housing 120. The housing 120 may accommodate the nut body 110 therein. The central portion of the nut body 110 may have a mounting hole 117 with internal threads, into which fasteners with external threads may be screwed.

[0077] Between the nut body 110 and the housing 120 Figure 1 A gap may be left in the X direction as shown to compensate for positional deviations of the insert nut 100 during installation, which will be described in detail below.

[0078] The nut body 110 can be made of materials such as carbon steel, alloy steel, stainless steel, copper, and aluminum to meet certain hardness and strength requirements. The shell 120 can be made of materials such as plastic, alloy steel, stainless steel, copper, and aluminum, and in addition to meeting certain hardness and strength requirements, it can also have a certain degree of elasticity and toughness.

[0079] The surfaces of the nut body 110 and the housing 120 can be treated for rust prevention and corrosion prevention, such as nickel plating or zinc plating.

[0080] See Figure 3The nut body 110 can be assembled with the housing 120 along the Z direction shown in the figure. The first end 111 of the nut body 110 can be fastened to the engaging body 121 of the housing 120. The engaging body 121 may be provided with an engaging port 125 for the first end 111 to be inserted therein to achieve a form-fit fastening connection. The first end 111 can also be connected and fastened to the engaging port 125 by riveting, welding, or other methods.

[0081] In one embodiment, the outer contour of the first end portion 111 and the contour of the joint 125 are non-circular shapes that match each other, preventing relative rotation. For example, the outer contour of the first end portion 111 may be a rounded rectangle (i.e., formed by two opposite rounded edges and two opposite straight edges). The outer contour dimension of the first end portion 111 may be slightly larger than the dimension of the joint 125 to facilitate riveting and fastening. Of course, the outer contour dimension of the first end portion 111 may also be equal to or slightly smaller than the dimension of the joint 125, and the two may be connected and fastened by other auxiliary fastening methods such as welding.

[0082] See Figure 4 and Figure 5 It shows the structure of the individual nut body 110.

[0083] The nut body 110 may include a cylindrical portion 118 located at its longitudinal center and side supports 119 connected to opposite sides of the cylindrical portion 118. The two side supports 119 are symmetrically arranged with respect to the longitudinal center of the nut body 110. A mounting hole 117 is provided at the longitudinal center of the cylindrical portion 118.

[0084] The nut body 110 may include a first end 111, a second end 112, a first side 113, a second side 114, a third side 115, and a fourth side 116.

[0085] The first end portion 111 may extend from one end of the cylindrical portion 118 toward the engagement port 125 of the engaging body 121, and has a smaller radial dimension, or outer contour shape, than the cylindrical portion 118, thereby forming a stepped portion 1191 at this end with the cylindrical portion 118. When the nut body 110 is fastened in the housing 120, the stepped portion 1191 can be firmly pressed against the periphery of the engagement port 125 to facilitate the positioning of the nut body 110.

[0086] Optionally, the outer contour of the columnar portion 118 can be a combined columnar configuration with one end larger and the other end smaller. That is, the columnar portion 118 has a larger end 1181 with a larger circumferential dimension and a smaller end 1182 with a smaller circumferential dimension. The larger end 1181 of the columnar portion 118 is connected to the first end portion 111 to facilitate the formation of a stepped portion 1191. The larger end 1181 can also transition to the smaller end 1182 in a conical shape, but this disclosure is not limited thereto.

[0087] On the arcuate circumferential surface of the larger end 1181 of the cylindrical portion 118, at positions corresponding to the third side surface 115 and the fourth side surface 116, a longitudinal cutting plane 1183 can be symmetrically provided to reduce the radial dimension of the larger end 1181 along the X-axis direction shown in the figure, thereby facilitating installation into the housing 120.

[0088] like Figure 4 As shown, a mounting hole 117 with internal threads can be provided on the second end 112 of the nut body 110 for connection with a fastener. The fastener can be, for example, a screw, bolt, or other component, as long as it has external threads corresponding to the internal threads of the nut body 110; this disclosure does not impose any limitations. The second end 112 can form an exposed plane perpendicular to the longitudinal centerline of the nut body 110, i.e., the longitudinal centerline of the mounting hole 117 (e.g., ...). Figure 8 , Figure 11-13 (As shown). This plane may protrude slightly from the housing 120.

[0089] The first side 113 and the second side 114 of the nut body 110 can be the surfaces of the two side supports 119 that are away from the columnar portion 118.

[0090] The side bracket 119 may extend along the entire longitudinal direction of the cylindrical portion 118. Optionally, the side bracket 119 may have a configuration that tapers radially toward the cylindrical portion 118 (i.e., has a tapered cross-sectional profile), and / or a configuration that tapers in the direction from the second end 112 toward the first end 111 (and has a tapered longitudinal cross-sectional profile). The side bracket 119 may have an end face flush with the end face of the cylindrical portion 118 away from the first end 111 (i.e., the end face of the smaller end 1182).

[0091] Optionally, the first side surface 113 of the nut body 110 may form a plane with a groove. A groove recessed toward the cylindrical portion 118 may be formed on the first side surface 113, and the two sides of the first side surface 113 adjacent to the groove in the X direction are inclined downwards (along the negative Z-axis direction) and inwards (along the negative Y-axis direction) (e.g.) Figure 11-12 (As shown). The rectangular plane of the first side 113 above the groove can be formed to be substantially perpendicular to the horizontal plane.

[0092] The third side 115 of the nut body 110 can be formed as an arc surface on its upper part (along the positive direction of the Z-axis) and as a plane formed by three adjacent rectangular surfaces on its lower part (along the negative direction of the Z-axis). The arc surface on the upper part and the rectangular surface on the lower part can be smoothly connected.

[0093] In one embodiment, the first side 113 and the third side 115 of the nut body 110 may be formed as a rectangular plane, a circular arc surface and a plane composed of two rectangular surfaces, or other planes or irregular surfaces or combinations thereof, and this disclosure is not limited thereto.

[0094] See also Figure 5 The first end 111 of the nut body 110 can be configured as a rounded rectangular cube with a hollow hole. The hollow hole of the first end 111 can communicate with the internal threaded hole of the second end 112 to form a space for accommodating the fastener.

[0095] See Figure 6 and Figure 7 The diagram illustrates the structure of a separate housing 120. The housing 120 may include a coupling body 121, a first arm 122, and a second arm 122.

[0096] like Figure 6 As shown, the housing 120 can be a one-piece component made from a single sheet metal. Optionally, the joining body 121 of the housing 120 can be formed by stacking one part of the sheet metal onto another part. A joining port 125 can be provided on the joining body 121. As mentioned above, the joining port 125 can be used to connect and fasten to the first end 111 of the nut body 110, thereby fixing the nut body 110 to the housing 120. The first arm 122 and the second arm 123 of the housing 120 can be connected to the two sides extending in the Y direction of the joining body 121. The first arm 122 and the second arm 123 can be integrally formed with the joining body 121, or they can be connected by welding, sheet metal, or other methods. The first arm 122 and the second arm 123 can be arranged approximately perpendicular to the joining body 121. The first arm 122, the second arm 123, and the joining body 121 can form a first space to accommodate the nut body 110.

[0097] In one embodiment, if necessary, the housing 120 may also be provided with a third arm and a fourth arm on two opposite sides where the first arm 122 and the second arm 123 are not provided. The first arm 122, the second arm 123, the third arm, the fourth arm and the engaging body 121 together can restrict the first space 129 for accommodating the nut body 110.

[0098] In one embodiment, the first arm 122 and the second arm 123 may extend outward from the engagement body 121 at a small obtuse angle, thereby increasing the size of the first space 129 that accommodates the nut body 110.

[0099] The housing 120 may further include a first wing 126 and a second wing 127. The first arm 122 and the second arm 123 may each have the first wing 126 and the second wing 127 connected to their respective ends along the positive Z-direction. The first wing 126 and the second wing 127 may be configured to be parallel to the connecting body 121. The first wing 126 and the second wing 127 may be integrally formed with the first arm 122 and the second arm 123, or they may be connected by welding, sheet metal work, or other methods.

[0100] In one embodiment, the first wing 126 and the second wing 127 may be configured such that the angle between them and the corresponding first arm 122 and second arm 123 is equal to or less than 90 degrees.

[0101] In one embodiment, the housing 120 may be a one-piece component made from a single sheet metal. Alternatively, the housing 120 may be a one-piece piece formed by stamping a single sheet metal. To enhance the supporting strength of the housing 120, its connecting body 121 may be formed by stacking one portion of the sheet metal onto another. The first arm 122 and the second arm 123 may be bent substantially perpendicular to the connecting body 121 from opposite sides of the connecting body 121 in the same direction. The first wing 126 and the second wing 127 may be bent substantially perpendicular to the first arm 122 and the second arm 123 from their free ends away from the connecting body 121.

[0102] The housing 120 may further include a latching portion 124. The latching portion 124 may protrude from the outer surfaces of the first arm 122 and the second arm 123. Specifically, the latching portion 124 on the first arm 122 may protrude along the negative X direction, and the latching portion 124 on the second arm 123 may protrude along the positive X direction. The latching portion 124 on the first arm 122 may be disposed opposite to the latching portion 124 on the second arm 123.

[0103] Optionally, the latching portion 124 can be symmetrically arranged at the same position on the first arm 122 and the second arm 123. The latching portion 124 can be integrally formed with the first arm 122 and the second arm 123 respectively, or it can be connected by welding, sheet metal or other methods. The latching portion 124 can define a second space 130 on one side of the housing 120 with the corresponding first arm 122 and the first wing 126, and the latching portion 124 can define a second space 130 on the other side of the housing 120 with the corresponding second arm 123 and the second wing 127. The latching portion 124 can have a pressing surface 1241 and two latching sides 1242, wherein the two latching sides 1242 are located on both sides of the pressing surface 1241 along the Y direction. The latching space 1243 formed by the pressing surface 1241 and the two latching sides 1242 can provide a certain elasticity to the latching portion 124, which facilitates the installation or removal of the insert nut 100 and the carrier, as will be described in detail below.

[0104] In one embodiment, the latching portion 124 may be in the shape of an oblique cone. The pressing surface 1241 of the latching portion 124 extends outward from the outer surface of the first wing 126 and the second wing 127 at an acute angle toward their free ends. The two sides of the pressing surface 1241 are the latching side surfaces 1242, and the latching side surfaces 1242 on both sides may be arranged substantially parallel to each other.

[0105] The housing 120 may also include a through hole 128. The through hole 128 may be located above the snap-fit ​​space 1243 along the positive Z-direction. Optionally, the through hole 128 may be located at the bend between the first wing 126 and the first arm 122. The through hole 128 may also be located at the bend between the second wing 127 and the second arm 123. The through hole 128 can save material costs while ensuring the strength of the housing 120.

[0106] In one embodiment, the opposing first arm 122 and second arm 123 may have the same shape and size (e.g., Figure 8 , Figure 13 As shown). The opposing first wing 126 and second wing 127 can have the same shape and size (e.g. Figure 8-10 , Figure 13 As shown). Each snap-fit ​​part 124 can have the same shape and size (e.g. Figure 8-13 As shown). Each through hole 128 can have the same shape and size (e.g. Figure 9-10 (As shown). That is, the first arm 122 and the second arm 123 can be arranged symmetrically with respect to the longitudinal center of the nut 100; the first wing 126 and the second wing 127 can be arranged symmetrically with respect to the longitudinal center of the nut 100; the snap-fit ​​part 124 can be arranged symmetrically with respect to the longitudinal center of the nut 100; and the through hole 128 can also be arranged symmetrically with respect to the longitudinal center of the nut 100.

[0107] Back Figure 1 and Figure 2 The first side 113 of the nut body 110 can be arranged adjacent to the first arm 122 and the second arm 123 in the X direction. There is a gap between the two sides of the first side 113 along the Z direction and the first arm 122 and the second arm 123, that is, the two vertical sides of the first side 113 are a certain distance away from the first arm 122 and the second arm 123. If the nut body 110 rotates within the housing 120, the gap between the first side 113 and the first arm 122 and the second arm 123 will disappear, that is, the first side 113 will interfere with the first arm 122 or the second arm 123, thereby preventing the nut body 110 from rotating further within the housing 120, achieving the effect of limiting and preventing rotation. The positional relationship of the second side 114 of the nut body 110 is similar to that of the first side 113, and it can also achieve the effect of limiting and preventing rotation, which will not be described in detail here.

[0108] See Figure 14 The diagram illustrates the assembly of the insert nut 100 and the carrier 200. The carrier 200 may have one or more mounting holes 210. The mounting holes 210 may have a stepped portion 211. The mounting holes 210 and the stepped portion 211 may be rectangular, matching the shape of the insert nut 100. The insert nut 100 can be installed with its bottom facing the mounting hole 210 of the carrier 200. Specifically, during the installation of the insert nut 100 and the carrier 200, the engaging body 121 of the housing 120 faces the mounting hole 210, and the first wing 126 and the second wing 127 of the housing 120 face the stepped portion 211. During installation, the snap-fit ​​portion 124 of the housing 120 first abuts against the step portion 211. Under the action of external force, the snap-fit ​​portion 124 is subjected to the force applied by the step portion 211 toward the nut body 110, causing the first arm 122 and the second arm 123 to move inward relative to the engaging body 121 through elastic deformation, thereby allowing the snap-fit ​​portion 124 to pass through the mounting hole 210. Subsequently, the force exerted by the stepped portion 211 on the latching portion 124 toward the nut body 110 disappears, and the first arm 122 and the second arm 123 reset, causing the stepped portion 211 to engage between the latching portion 124 of the first arm 122 and the first wing 126, and between the latching portion 124 of the second arm 123 and the second wing 127, thereby confining the carrier 200 within the second space 130 formed by the latching portion 124 and the first arm 122, the first wing 126, the second arm 123, and the second wing 127, that is, the embedded nut 100 engages with the carrier 200 (as shown in the image). Figure 16(As shown). The thickness of the first wing 126 and the second wing 127 can be less than the depth of the step portion 211, so that the embedded nut 100 will not protrude from the outer surface of the support member 200, making the appearance more aesthetically pleasing and reducing the risk of the embedded nut 100 being bumped or knocked. If it is necessary to remove the embedded nut 100 from the support member 200, simply apply a force toward the nut body 110 to the snap-fit ​​portion 124, causing the snap-fit ​​portion 124 to disengage from the step portion 211, which will not be described in detail here.

[0109] See also Figure 15 The diagram shows a top view of an insert nut 100 mounted on a carrier 200. The second end 112 of the nut body 110 can abut against the side corresponding to the mounting hole 210, thereby helping to restrict the rotation of the nut body 110. Of course, in other embodiments, the side of the second end 112 can be configured in other positional relationships, as long as it can abut against the side corresponding to the mounting hole 210 and restrict the rotation of the nut body 110; this disclosure is not limited thereto.

[0110] It is understood that, in one embodiment, the inlaid nut 100 can be directly installed on the mounting hole 210 of the carrier 200, and there is no need to provide a stepped portion 211 around the mounting hole 210.

[0111] Although this disclosure has been described with reference to exemplary embodiments, the terminology used is descriptive and exemplary, and not restrictive.
