Description

Technical Field

[0001] This disclosure relates to electrical component enclosures, and more particularly to latches for securing covers to electrical component enclosures. Background Technology

[0002] Enclosures for housing electrical components such as printed circuit boards (PCBs), electronic modules, and the like are known. Enclosures are typically made of plastic or metal and are designed to house the electrical components within fixed recesses. These enclosures are suitable for installation in various indoor and outdoor environments to meet the needs of the end application.

[0003] Electrical component enclosures are known to have movable panels or covers. The covers can be secured in place to the enclosure using various types of retaining latches.

[0004] It is known to actuate latching components by using a long, thin tool with a blade (such as a screwdriver) to allow the cap to be removed.

[0005] The process of using a tool to actuate a latching component is problematic. To actuate a latching component, the tool blade must be properly positioned to engage a specific latching element and force must be applied to that element. Properly positioning the tool blade to actuate small latching components can be difficult and time-consuming.

[0006] Because the latching element may be located within a housing recess or other protective structure to prevent accidental latching actuation, it is difficult or impossible to visually confirm the engagement of the components and actuation via the tool blade in the field. This may result in incorrect tool blade positioning.

[0007] When a release force is applied to the tool, improper positioning of the tool blade can lead to actuation failure of the latching element, unwanted placement of the tool blade away from the latching element, and potential damage to the housing or components contained therein.

[0008] Once the latching element is actuated, the user must use one free hand to remove the cap from the housing body while continuing to apply a release force to the latching element with the tool blade. The need to use both hands simultaneously to remove the cap complicates the process and further increases the risk of blade displacement.

[0009] Therefore, it is desirable to provide an electrical component enclosure that allows for improved latch actuation. This enclosure should allow actuation by a user using a tool blade, thereby overcoming the aforementioned challenges. Summary of the Invention

[0010] An electrical component enclosure assembly is disclosed that provides improved latch actuation and cover removal by using a hand tool (such as a screwdriver blade) with a flat blade.

[0011] The disclosed cover includes elements that properly position a tool blade near the latching element and facilitate the application of force by the tool blade to actuate the latching element and disengage the cover in a single action. The cover allows for simplified disengagement of the cover from the cover. The disclosed cover also provides physical feedback to the user to notify the user of proper latch actuation during cover removal.

[0012] As the description proceeds, other objects and features will become apparent, especially when taken in conjunction with the accompanying drawings. Attached Figure Description

[0031] Figure 1 An electrical component enclosure assembly 10 is shown, having an enclosure body 12 and an enclosure cover or enclosure panel 14. The enclosure body 12 and the enclosure panel 14 may each be molded from plastic, other insulating materials, or formed of metal.

[0032] As shown in the figure, the main body 12 of the enclosure is generally rectangular in shape and consists of five main walls: a top wall 18, a bottom wall 20, side walls 22 and 24, and a rear wall 26. An opening 28 of the enclosure leads into an internal cavity 30. The surrounding main walls define a generally rectangular cavity 30, having a major axis 32 extending from the enclosure opening 28 to the rear wall 26 and a minor axis 34 extending between the side walls 22 and 24. The minor axis 34 extends generally parallel to the enclosure opening 28.

[0033] Two cover assembly feet 36 extend from the bottom of the body 12 near the side walls 22, 24 and bottom wall 20 of the cover body. Each foot 36 is generally rectangular in shape and may have a foot hole 38 extending through it. Figure 5 As shown, the foot hole 38 can be surrounded by the foot 36 or open to the outside of the foot 36. The foot hole 38 can be used to secure the cover assembly 10 to the support surface by extending a fastener through the hole 38.

[0034] The internal cavity 30 of the enclosure may include mounting elements for securely mounting printed circuit boards, electronic modules, and similar electrical components therein. The enclosure body sidewalls 22, 24, having internal sidewall surfaces 40, 42, may each have a PCB retainer slot 44. Each retainer slot 44 faces a retainer slot 44 on the opposing internal sidewall surface. The slots 44 are sized to accommodate printed circuit boards or similar generally flat electrical component elements.

[0035] In other embodiments, the internal cavity 30 of the enclosure may have other mounting elements to facilitate the installation of electrical components therein. Electrical components can be mounted to the inner wall surface of the enclosure body using conventional fasteners, adhesives, or the like.

[0036] The cover or cover panel 14 has a generally flat rectangular body 50. The body 50 has a front portion 52 and a rear portion 54. The body 50 includes a top portion 56, a bottom portion 58, and side portions 60 and 62.

[0037] The rear portion 54 of the cover or panel 14 may include a circumferential mounting flange 64 extending away from the portion 54. The mounting flange 64 is formed of a flange wall 66 having a generally uniform thickness and a generally rectangular shape, extending circumferentially near portions 56, 58, 60, and 62 of the body 50. When the cover or panel 14 engages the housing body 12 at the closure of the assembly 10, the mounting flange 64 is adapted to fit within the interior of the housing opening 28.

[0038] Mounting flange 64 may include a circumferential washer 68 located on the outside of mounting flange 64. The washer 68 may be made of silicone, rubber or similar elastomer to provide an improved fit between mounting flange 64 and the interior of housing opening 28, and to provide protection against moisture ingress, environmental contamination and the like into cavity 30 at the closure of assembly 10.

[0039] The rear facet 54 of the cover or panel 14 may also include a pair of PCB retainer slots 70, such as Figure 7 As shown, PCB retainer slots are located between opposing cover-side portions 60, 62 and extend inwardly from flange wall 66. PCB retainer slots 70 face each other and are sized to accommodate printed circuit boards or similar generally flat electrical component elements, similar to slot 44 described above. Slot 70 may include a lower PCB mounting flange 72 that extends away from face 54 and has flange mounting holes 74.

[0040] In an embodiment, a printed circuit board 80 or similar electrical component comprising generally flat elements may be mounted to assembly 10. This can be achieved by inserting a board 80 having opposing side edges 82 into cavity 30 such that edges 82 engage PCB retainer slots 40 and / or PCB retainer slots 70. In an embodiment, printed circuit board 80 may include one or more mounting holes 84 located near edges 82 and aligned with flange mounting holes 74 during board mounting. Quicker positioning via aligned holes 74 and 84 can be used to secure printed circuit board 80 to panel 14.

[0041] Electrical components

[0042] The enclosure assembly 10 includes a pair of enclosure panel actuation assemblies 100, each located on the upper sidewalls 22 and 24 near the enclosure opening 28.

[0043] Each actuation assembly 100 is formed by a retaining latch assembly 102 located on the housing body 12 and a latch engagement assembly 104 located on the panel 14.

[0044] Each retaining latch assembly 102 is located on the sidewalls 22, 24 of the housing body and near the opening 28 of the housing.

[0045] Each retaining latch assembly 102 includes a latch arm 105 extending from a latch base 106 to a latch hook 108. The latch base 106 is coupled to the sidewalls 22, 24 of the housing body and may include a latch safety aperture 107 extending from the top of the base near the top wall 18 to the bottom of the base near the bottom wall 20.

[0046] The latch arm 105 is flexible and allows deflection during assembly and use as described below.

[0047] The latch hook 108 includes a latch head 110 having a cam surface 112 and a hook retaining surface 114.

[0048] Each latch engagement assembly 104 is located on the panel portions 60, 62 and extends away from the front portion 52, close to the mounting flange 64. See also Figure 11 .

[0049] Each latch engagement assembly 104 includes a generally C-shaped latch engagement assembly wall 120, such as Figure 7 As shown, the latch engagement assembly wall has a top wall 122, a side wall 124, and a bottom wall 126. A tool positioning hole 128 extends through the top wall 122 and is located near the panel body 50.

[0050] The tool positioning hole 128 includes a peripheral opening having a chamfered surface 130 positioned adjacent to the outer surface of the top wall 122.

[0051] The outer surface of the top wall 122 may include a locating mark 131 near the tool locating hole 128. In the figures, the locating mark 131 is shown as an arrow pointing to the hole 128, but other locating symbols may also be used. The use of the arrow symbol can indicate the direction of rotation of the tool inserted into the tool locating hole 128 to actuate the component latch during use of the component as described below.

[0052] When the tool blade 202 is fully inserted into the tool positioning cavity 142, the tool 200 moves along the direction of arrow 204 from... Figure 17 The vertical position shown is rotated to, as Figure 18 The tool is positioned at an angle as shown. At this point, the tool blade 202 is primarily in contact with the ramp surface 146 of the tool positioning hole. As the tool 200 rotates further in the direction of arrow 204, the tool 200 engages and pivots against the cam surface 130, thereby disengaging the tool blade 202 from the ramp surface 146 and engaging the cam surface 112, as shown... Figure 19 The actuation latch hook 108 shown in the figure leaves the retaining element 136.

[0053] The top wall 122 and the bottom wall 126 include aligned engagement component safety apertures 132.

[0054] Latch engagement assembly wall 120 defines a latch engagement assembly cavity 134 within each latch engagement assembly 104. The cavity 134 is generally defined by walls 122, 124, 126 and a panel mounting flange 64. See also Figure 7 and 11 .

[0055] Within the cavity 134, the component sidewall 124 includes a retaining element 136 having a cam surface 138 and a retaining surface 140.

[0056] The cavity 134 also includes a tool positioning cavity 142, which is generally defined by the retaining surface 140, the sidewall 124 and the rear portion 54 of the panel 14.

[0057] The tool positioning cavity 142 is located below the tool positioning aperture 128 and is usually continuous with the tool positioning aperture 128.

[0058] The tool positioning cavity 142 includes a ramp element 144 having a ramp surface 146. The ramp surface 146 is generally opposed to the wall 124 and faces the flange 64. The ramp surface 146 gradually tapers outward as it extends from the tool positioning aperture 128 to the base 148 of the ramp element. See also Figure 16 .

[0059] like Figure 8As shown, the tool positioning hole 128 has a generally rectangular cross-section 150, which has a major axis 152 and a minor axis 154. In alternative component embodiments, the tool positioning hole 128 may have a non-rectangular cross-section 150, including a square cross-section, a circular cross-section, and cross-sections with other shapes.

[0060] When the cover panel 14 is installed onto the cover body 12 in the assembly 10, the minor axis 154 of the small hole 128 is offset by an angle A from the minor axis 34 of the cavity 30. Angle A can be approximately 25 degrees. In an embodiment, angle A can be in the range of 20 degrees and 30 degrees.

[0061] In the component embodiment, the spindle 152 of the aperture 128 is biased from the spindle 32 of the cavity 30 to the same extent as the cam surface 112 of the latch hook 108 is biased from the spindle 32 of the cavity 30. As disclosed below, this configuration allows reliable contact between the tool insert inserted into the tool positioning aperture 128 and the cam surface 112.

[0062] The rectangular cross-section 150 of the tool positioning hole 128 is designed to allow the insertion of tools with flat blades (such as flat screwdriver blades) in the assembly embodiment. The length of the spindle 32 may be approximately 3.6 mm, and the length of the short shaft 34 may be approximately 2.6 mm to allow the insertion of flat screwdriver blades of the corresponding size.

[0063] The use of the electrical component enclosure assembly 10 will now be described.

[0064] Figure 1 An electrical component enclosure assembly 10 is shown, which has an enclosure panel 14 fixed to an enclosure body 12. In the assembly 10, an enclosure actuation assembly 100 secures the panel 14 to the body 12 and allows the panel 14 to be removed therefrom using a screwdriver or similar tool with a flat blade.

[0065] Figure 13 This is a cross-sectional view of the actuation assembly 100 in a fixed position, having a housing panel 14 fixed to the housing body 12. In the fixed position, the latch assembly 102 engages the latch engagement assembly 104 to secure the panel 14 to the housing body 12. The latch hook 108 engages the retaining element 136 such that the hook retaining surface 114 approaches the retaining surface 140.

[0066] In the fixed position, the latch assembly latch safety hole 107 and the latch engagement assembly safety hole 132 are aligned to allow for the placement of a safety retaining strap, similar to a zip-tie of a safety retaining element, to secure the assembly 10 in the fixed position, prevent interference with the assembly 10 and / or provide indication in the event of unauthorized use of the assembly.

[0067] Figure 14and Figure 15 The tool 200 is positioned with its blade 202 close to the actuation assembly 100 and the tool positioning aperture 128 as the first step in the process of separating the panel 14 from the body 12 using the actuation assembly 100.

[0068] Hand tool 200 is shown in the figure as a flathead screwdriver with a tool blade or tool tip 202. Other types of hand tools can also be considered for use with component 10, such tools having an elongated shaft terminating at an end that generally conforms to the shaft, including Phillips head screwdrivers, awls, and similar tools, provided that the shaft end fits properly within the tool positioning hole 128.

[0069] The component positioning mark 131 guides the user to insert the tool blade 202 into the tool positioning hole 128.

[0070] Figure 16 and 17 A tool blade 202 is shown inserted through the tool positioning hole 128 and partially into the tool positioning cavity 142. At this time, the tool blade 202 is in partial contact with the ramp surface 146 of the ramp element 144.

[0071] Figure 18 and 21 The tool blade 202 is shown fully inserted into the tool positioning cavity 142. At this point, the tool blade 202 is in full contact with the ramp element 144 and the chamfered tool surface 130. The end of the tool blade 202 is located near the latch head 110.

[0072] Additionally, when the tool blade 202 is fully inserted into the tool positioning cavity 142, the tool 200 moves along the direction of arrow 204 from... Figure 17 The vertical position shown is rotated to, as Figure 18 The position shown is at an angle.

[0073] Figure 19 and 22 A tool blade 202 is shown that pivots against a latch head 110 to apply a displacement force. The tool 200 pivots against a chamfered tool surface 130 to bring the tool blade into contact with a latch having a cam surface 112.

[0074] Figure 24 The tool blade 202 is shown to disengage the latch head 110 from the retaining element 136, causing the hook retaining surface 114 to shift from the retaining surface 140.

[0075] During the latch disengagement process, the tool blade 202 applies a displacement force 210, such as Figure 24As shown, the displacement force has force component vectors 212 and 213. Component vector 214 deflects the latch arm 105 away from the retaining surface 140. Component vector 212 provides displacement of the panel 14 away from the body 12. This simultaneous action in one step effectively disengages the panel 14 from the base 12.

[0076] The rectangular cross-section 150 of the tool positioning orifice 128 can be positioned such that the major axis 152 is substantially parallel to the cam surface 112 of the latch hook portion 108. This allows the blade 202, inserted into the orifice 128 and the tool positioning cavity 142, to establish reliable contact with the latch head and the cam surface 112. Furthermore, the rectangular cross-section 150 is sized to prevent mispositioning of the blade 202, ensuring that the blade correctly actuates the latch arm 105. This positioning of the tool positioning orifice 128 also ensures that the tool blade 202 provides a displacement force 210 with force component vectors 212 and 213 as described herein.

[0077] The process is repeated for both actuation components 100 to allow panel 14 to be removed from body 12.

[0078] When a displacement force 210 is applied appropriately, the panel 14 is partially pushed away from the body 12 as the latch head cam surface 112 travels along the cam surface 138. This movement provides the user with physical feedback confirming the correct latch actuation for panel removal.

[0079] Although this disclosure shows an electrical component housing 10 having a pair of actuation assemblies 100 located on opposing side housings 12 to secure a panel thereto, alternative embodiments are conceivable. Alternative embodiments may include housings having a single cover retaining assembly 100 and housings having more than two actuation assemblies 100.

[0080] Similarly, although this disclosure discloses an actuation assembly 100 having a retaining latch assembly 102 located on the housing body 12 and a latch engagement assembly 104 located on the panel 14, alternative embodiments are conceivable. Alternative embodiments may include an assembly having an actuation assembly 100 having a retaining latch assembly 102 located on the panel 14 and a latch engagement assembly 104 located on the body 12.

[0081] Although this disclosure discloses and describes various embodiments, it should be understood that modifications are possible with respect to this disclosure, and that this disclosure is not limited to the precise details described above, but includes such variations and changes that fall within the scope of the appended claims.
