Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of electrical connectors, and covers for protecting them, for example, from being touched by users to avoid accidents. Background Art
[0002] As is known, in order to prevent the user from touching any conductive part, it is necessary to cover the electrical connector. Such a cover is usually made of at least two different plastic parts, which are intended to be assembled to cover the electrical connector.
[0003] Such solutions are often difficult to assemble and / or offer too little protection to meet the IP20 requirement, ie protection against intrusion of any object 12.5 mm wide, such as a user's finger.
[0004] Furthermore, the electrical connectors can have different sizes, depending on the number of cables to be assembled. Different sized connections therefore mean different sized and sometimes differently shaped cover boxes, which implies non-negligible costs.
[0005] The present disclosure aims to alleviate at least some of the above disadvantages. Summary of the invention
[0006] The present disclosure relates to a cover box for protecting an electrical connector, the cover box comprising a first half shell and a second half shell, the first half shell and the second half shell defining an internal volume configured to accommodate at least part of the electrical connector, each half shell comprising:
[0007] - a recess opening into said internal volume;
[0008] - latching device;
[0009] The half shells can be assembled together by the cooperation of the latching device of the first half shell and the latching device of the second half shell. When the half shells are assembled together, the recess of the first half shell faces the recess of the second half shell. The electrical connector includes a screw and a nut that cooperates with the screw. The nut can be engaged in the recess of the first half shell, and the head of the screw can be engaged in the recess of the second half shell.
[0010] This solution provides a safe cover box which requires a simple design and minimum costs. Furthermore, the box is held in place by the cooperation between the recess and the screws and nuts, the dimensions of which vary little. Thus, the same cover box can be used for electrical connectors of different thicknesses. The cover box according to the invention can therefore be used for a variety of electrical connectors, as long as they include screws and nuts.
[0011] The size of the cover box can allow application to a variety of electrical connectors. The cover box can be designed, for example, in 2, 3 or more sizes, which can cover most electrical connectors. Therefore, the size change from one electrical connector to another at most means using different available sizes, rather than having to design a new cover specifically for each different connector.
[0012] This solution does not require any additional fixing parts to cover the electrical connections and is therefore easy to install, manufacture and maintain.
[0013] Both half shells can be obtained from molded plastic, for example by injection molding. The plastic material can be polyethylene or polycarbonate.
[0014] In an embodiment, once the two half shells are latched together, the cover box does not include any opening larger than 12.5 mm. This allows meeting IP20 safety requirements, which prevents smaller objects or users (such as the user's fingers) from accessing the electrical components inside the cover box.
[0015] In an embodiment, each half shell is generally parallelepiped-shaped, comprising four outer walls and a base wall, the base wall defining an open volume on one side that remains open. The open side of the first half shell may include a profile designed to accommodate the open side of the second half shell. In an embodiment, the profile of the first half shell may be complementary to the profile of the second half shell to continuously close the gap between the two half shells.
[0016] Generally, each half shell may include an elongated direction from one smaller side to the other smaller side, a transverse direction from one larger side to the other larger side, and a vertical direction from the base through the opposite open sides.
[0017] In an embodiment, each half shell may comprise an outer wall which is open to allow one or more connection parts of the electrical connector to pass through the cover box. In an embodiment, the outline of the open volume defined by each half shell may be interrupted by a shorter outer wall to provide an open space in which one or more conductive parts may be accommodated. This allows the cover box to be closed around the electrical connector, including, for example, one or more rods. In an embodiment, on the opposite side, each half shell may comprise another opening, the outline being interrupted again to allow another conductive part to pass, such as one or more cables.
[0018] According to an embodiment, the recess can be any shape, as long as it can accommodate a nut and / or a screw head to prevent the half shells latched together from being pulled away or moved away from the electrical connector. The recess does not mean to prevent the cover box from rotating around the screw of the electrical connector, but at least means to include a surface that prevents any movement away from the screw along one or more cables. In an embodiment, the recess can be a cylindrical shaft protruding from the surface, and the cylindrical shaft defines the internal volume inside the cover box so that the recesses of each half shell can face each other when latched together. In an embodiment, it can be a well without any protruding walls. In an embodiment, the recess can include an opening with a circular cross-section, and a hexagonal nut can be fixed in the opening. In an embodiment, the recess can include any polygonal cross-section, as long as it can accommodate a nut or a screw head.
[0019] In an embodiment, the recess features a cross-section, such as a circular cross-section, which allows a small rotational travel of the connector, which may prevent premature breakage of the cover box when pushed by manipulation on the cable of the electrical connector or surrounding equipment.
[0020] In an embodiment, the recess may include a depth determined to allow for accommodation of at least a portion of the nut in addition to an excess length of the screw extending through the nut.
[0021] In an embodiment, the first and second half shells are identical. This means that they comprise the same shape and the same dimensions. In embodiments where the half shells are obtained by moulding a plastic material, the two half shells can generally be manufactured in similar moulds, or in the same mould.
[0022] In an embodiment where both half shells are identical, the latch means of each half shell may include male and female portions, each portion being located on opposite sides of the half shells, the male and female portions of the first half shell being configured to interface with the female and male portions of the second half shell, respectively.
[0023] In an embodiment, the latching means comprises a tab and a notch, the tab and the notch of the first half-shell being capable of cooperating with the notch and the tab of the second half-shell, respectively.
[0024] In an embodiment, the latching means are configured to cooperate with each other by elastic deformation of at least one component. The latching means are then configured to be detached by elastic deformation of it or another deformable component.
[0025] In an embodiment, the tab may be elastically deformable and protrude vertically from the half shell (e.g., from the outer wall) and include a free end. The free end may include a tooth or any protrusion with a stop surface. The elastic deformation of the tab allows the protrusion to move at least laterally along the cover box. The recess of each half shell may include a hollow sleeve extending vertically and including two openings at its ends, which are configured to pass through the elongated tab of the other half shell, the tooth includes a biasing surface to force the tab out of the static state when the tab passes through the sleeve to reach a bent state, and then the sleeve includes a stop edge, which is configured to block the stop surface of the tooth when the tab returns to its static state, and the cooperation between the stop surface and the stop edge prevents the two half shells from being disassembled.
[0026] In an embodiment, the latch device may include two safety walls extending vertically on both sides of the latch device, the safety walls being at a certain distance from each other, thereby preventing objects greater than the distance from passing between the safety walls and reaching the latch device. The distance may be determined according to the object to be prevented from intrusion.
[0027] In an embodiment, the latch device is configured to be disassembled by deformation of at least one component, and this safety wall is particularly useful for preventing a user from disassembling the latch device. In this case, the distance between the two safety walls may be less than the size of a finger, for example 12.5 mm.
[0028] In an embodiment, the safety wall may be located at a distance that prevents intrusion of fingers but allows intrusion of smaller tools (e.g. a screwdriver) that an authorized user may have, for example to bend back the latch means and allow opening of the cover box for a determined purpose (e.g. emergency reasons or maintainability).
[0029] Each safety wall comprises a first and a second part, the first half shell comprising the first part and the second half shell comprising the second part, the two parts of each safety wall defining an extension of each other when the first half shell and the second half shell are assembled. Such an embodiment helps to prevent the manufacture of protruding parts that are too long, which may break during transportation for installation. Designing a second part for each safety wall allows the length of this part to be increased without increasing the risk of breakage. Furthermore, when combined with an embodiment in which the half shells are molded of plastic, the shorter protrusions allow for an easier demoulding operation, thereby minimizing the risk of forming undercuts.
[0030] In an embodiment, the two safety walls may comprise two inclined offset guide surfaces defining two slopes leading to the space between the two safety walls, the guide surface of the first half-shell being able to guide the latching means of the second half-shell between the two safety walls.
[0031] In an embodiment, the guide surface may be in the shape of a chamfer, or may include a radius, or any shape that may induce a centering function to guide the mating latching device towards the space between the two safety walls.
[0032] In an embodiment, each half-shell comprises an air inlet defining at least one hole to link the inner volume to the outside of the cover box. In fact, the electrical connector may heat up during use, and the lack of air circulation around the connector may cause overheating, thereby damaging the assembled conductive parts and / or the cover box, or even causing a fire.
[0033] In an embodiment, the air inlet may have an elongated shape, such as being elongated laterally, and the width may be determined to prevent intrusion of larger objects, such as being inaccessible to a user with a finger. The width of each air inlet may be, for example, less than 12.5 mm to meet IP20 requirements.
[0034] In an embodiment, each half shell may include a cable passage defining a hole, the hole including a first and / or second portion of the hole, the first half shell including the first portion of the hole, and / or the second half shell including the second portion of the hole, each of the first and / or second portions of the hole enabling passage of a cable of the electrical connector. This allows the two half shells to be fully assembled together without any obstruction preventing the latching device from mating.
[0035] In an embodiment, the first and second portions of the hole can be obscured by at least one removable cover. This feature can allow the portion of the hole to be adjusted according to the number and size of cables of the electrical assembly. Each removable component can be configured to obscure a surface corresponding to a possible reference cross-section of the cable to cover at least most of the possible configurations of the electrical connector.
[0036] In an embodiment, a first larger detachable part may include a hole that is blocked by a smaller detachable part, which in turn may include a smaller hole that is blocked by an even smaller detachable part, etc. In this case, during the installation operation, depending on the size and number of cables, one can remove one or more of the corresponding parts to form an opening of suitable size to perfectly fit the cables. In this way, even if the size and number of cables change, the gap can be kept as small as possible. For example, the detachable parts can be designed to always keep the gap between the cable and the cover box less than 12.5 mm to meet IP20 requirements.
[0037] In an embodiment, when the first half shell and the second half shell are assembled together and each part of the hole allows the cable of the electrical connector to pass through, the cover box may include a shielding tab, the first half shell includes a first part of the shielding tab and / or the second half shell includes a second part of the shielding tab, and the shielding tab is configured to shield at least a part of the space between the cables. The shielding tab or each part of the shielding tab may have a curved edge to match the shape of the cable. This allows the gap between the cables to be filled or at least partially filled to prevent the intrusion of objects, such as the user's fingers.
[0038] In an embodiment, the first and / or second portion of the shield tab is a rigid portion protruding from their respective half-shell, each portion of the shield tab protruding in a manner that is not perpendicular to the cable.
[0039] In an embodiment, one or more portions of the shield tab may include a hinge, such as a deformable hinge, so that the shield tab can be folded into position, such as perpendicular to the cables, to fill the gap between the cables. When combined with an embodiment where both half shells are identical, each half of the shield tab including a hinge can be designed to have a specific shape that allows the two halves to fold without interfering with each other and / or the cables.
[0040] In an embodiment, the shielding tab may be formed by one of the two half shells, the other not including any part of the shielding tab.
[0041] In an embodiment, each half shell may include a centering hole and a pin, and when the half shells are assembled together, the pin and the centering hole of the first half shell can respectively cooperate with the centering hole and the pin of the second half shell, and the centering hole and the pin can make the latching device of the first half shell face the latching device of the second half shell. This helps to assemble the two half shells together. In addition, the cooperation between the pin and the hole can help to strengthen the cover box to minimize possible deformation near the junction between the two half shells.
[0042] In an embodiment, the pin may have a cross-shaped cross-section.
[0043] In an embodiment, the pin may include an offset top guide surface, the guide surface forming a bevel configured to guide the pin into the centering hole.
[0044] In an embodiment, the top guide surface may be chamfered in shape, or may include a radius, or any shape that may create a centering function to guide the fit between the pin and the hole.
[0045] The present invention relates to an assembly comprising the above-mentioned cover box and an electrical connector, comprising:
[0046] - rod;
[0047] - at least one annular tongue, each annular tongue being located at one end of the cable;
[0048] - a screw, inserted through the rod and the annular tongue, the screw comprising a screw head and extending in a first direction;
[0049] - and a nut cooperating with the screw head to fasten the annular tongue to the rod;
[0050] - one or more optional sheets,
[0051] The electrical connector is at least partially received by the cover box.
[0052] Generally, a rod is a general term referring to any conductive component configured to be connected to another conductive component by at least one screw and a nut. In an embodiment, the rod is a copper rod. In an embodiment, the rod includes a hole or opening configured to allow the screw to pass through.
[0053] Generally, a ring tongue is a generic term referring to any conductive component that is fixed to the end of a cable and is configured to be connected to another conductive component by at least one screw and nut. The ring tongue usually includes a hole and / or an opening for the screw to pass through.
[0054] The present invention relates to a method for protecting an electrical connector of the above-mentioned assembly, wherein the annular tongue is connected to the rod by a fastening nut cooperating with the screw head, and the electrical connector is protected by a cover box of the assembly, the method comprising:
[0055] - a nut for engaging the first half-shell of the cover box with the electrical connector in the recess of the first half-shell;
[0056] - screw heads for the electrical connectors joining the second half-shell of the cover box to the recess of the second half-shell;
[0057] - Assembling the two half-shells by bringing them together in the direction of rotation, coupling the latching means of the first half-shell with the corresponding latching means of the second half-shell.
[0058] In the above method, the cover box can be installed around the already fastened electrical components without any installation or removal operation on the electrical components. This can further improve the safety of the cover box installation operation because there is no need to touch the electrical connectors. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] refer to Figure 1 , shows an electrical connector 1, comprising:
[0069] - Rod 2;
[0070] - at least one annular tongue 3, each annular tongue 4 being located at one end of a cable 4;
[0071] a screw 5 inserted through the rod 2 and the annular tongue 3 , the screw 5 comprising a screw head 52 and extending in a first direction Z;
[0072] - a nut 51 which cooperates with a screw head 52 to fasten the annular tongue 3 to the rod 2;
[0073] - and two tabs: one between the nut and the annular tongue, the other between the screw head 52 and the rod 2 .
[0074] Still refer to Figure 1 The electrical connector is protected by a cover box 10 comprising a first and a second half-shell 11 , 12 delimiting an internal volume V configured to accommodate at least part of the electrical connector 1 , each half-shell 11 , 12 comprising a recess 15 opening into said internal volume V.
[0075] In order to improve the clarity of the description of the drawings, the following three-axis reference system is considered: an elongation direction X, a lateral direction Y and a vertical direction Z.
[0076] like Figure 1As shown, the nut 51 of the electrical connector can engage in the recess of the first half-shell 11, the head 52 of the screw 5 can engage in the recess 15 of the second half-shell 12, and the latching means 16, 17 (not shown in the figure) maintain the two half-shells together, so that both the screw head 52 and the nut 51 are accommodated in the recess, thereby preventing the cover box from being pulled open or moved, in this case, away from the electrical connector along the cable. Here, the depth of the recess of the top half shell is sufficient to accommodate the nut and the part of the screw that passes through the nut and further passes through the other side of the nut. The top of the recess even acts as a stop surface and allows the cover box to rest on this part of the screw.
[0077] exist Figure 1 In the embodiment shown, a rod opening 13 is shown which is configured to allow the two half-shells to be assembled around the rod of the electrical connector without interfering with it.
[0078] Figure 2 and Figure 3 More details of an embodiment of the cover box are shown, in which the half shells are two identical parts. The half shells 11, 12 can be assembled together by the cooperation of the latching means 16, 17 of the first half shell 11 with the latching means 16, 17 of the second half shell 12, when the half shells 11, 12 are assembled together around the electrical connection, the recess 15 of the first half shell 11 faces the recess 15 of the second half shell 12 along the first direction Z, so as to accommodate the screw head and the nut.
[0079] The latching means 16 , 17 here comprise a tab 16 and a notch 17 , the tab 16 and notch 17 of the first half-shell 11 being able to cooperate with the notch 17 and tab 16 of the second half-shell 12 , respectively.
[0080] exist Figure 2 and Figure 3 In the embodiment shown, and Figure 5 and Figure 6 In the embodiment shown, the tab is an elastically deformable elongated tab 161, extending vertically from each half shell (e.g., from the outer wall) along a first direction Z and including a free end. The free end may include a tooth 162 with a stop surface 163. The elastic deformation of the tab allows the tooth 162 to move at least along the transverse direction Y of the cover box 10. The recess 17 of the first half shell 11 includes a vertically extending hollow sleeve 171 and includes two openings at its ends, which are configured to pass the elongated tab 161 of the other half shell all the way through. The tooth 162 includes a biasing surface 164 to force the elongated tab 161 out of the rest state when it enters the bent state through the sleeve 171, and then the sleeve includes a stop edge 172, which is configured to block the stop surface 163 of the tooth 162 when the tab returns to its rest state, and the cooperation between the stop surface 163 and the stop edge 172 prevents the two half shells 11, 12 from being disassembled.
[0081] In addition, if Figure 2 As shown, the free end of the tab 16 includes a slot 165 configured to receive the end of a tool that can be used to bend the tab back to its bent state to disassemble the two half-shells.
[0082] Still refer to Figure 2 and Figure 3 , shows an embodiment of an air inlet 20. Here, the air inlet 20 defines a plurality of holes to provide an air flow within the internal volume V, for example to cool the electrical connections. In this embodiment, the air inlets 20 are laterally elongated and their width is less than 12.5 mm.
[0083] according to Figure 2 In the embodiment shown, the cover box 10 comprises a cable channel 14, which defines a hole including a first hole portion 141 and a second hole portion 142, the first half shell 11 comprises the first hole portion 141, and the second half shell 12 comprises the second hole portion 142. Each of the first hole portion 141 and the second hole portion 142 enables the cable of the electrical connector 1 to pass through so as to avoid any interference when the two half shells 11, 12 are assembled together. In this embodiment, the first hole portion and the second hole portion 141, 142 are covered by a removable cover 143.
[0084] Still refer to Figure 2 and 3 , each half shell 11, 12 includes half of a shielding tab 19, which is configured to shield at least a portion of the space between the cables passed by the partial holes 141, 142. Here, each half of the shielding tab is a rigid part, protruding from the cover box in a manner not perpendicular to the cables, and each has two curved edges that match or approximately match the shape of the cables in order to perform their shielding function. When the space between the cables does not need to be shielded, the tab can, for example, be simply kept in place such as Figure 2 The position shown, or it can be cut away.
[0085] Still refer to Figure 2 , each half-shell 11, 12 comprises a centering hole 113 and a pin 114, and when the half-shells 11, 12 are assembled together, the pin 114 and the centering hole 113 of the first half-shell 11 can respectively cooperate with the centering hole 113 and the pin 114 of the second half-shell, and the centering hole 113 and the pin 114 can make the latching means 16, 17 of the first half-shell 11 face the latching means 16, 17 of the second half-shell 12. Here, the pin is designed to have a cross-shaped cross-section and comprises an offset top guide surface 115, which defines an inclined surface, which is configured to guide the pin into the centering hole when the two half-shells 11, 12 are approached together.
[0086] Reference Figure 4 , the recess is designed to have a circular cross section. This preferred design does not allow interference with the small angular travel of the cover box when assembled around the electrical connector, because the circular inner wall simply rotates around the hexagon of the nut or screw head. The travel amplitude is as Figure 5 As shown, in the present embodiment +5 / -5° is achieved.
[0087] Still refer to Figure 4 In order to work on most electrical connector sizes, the cover box, especially the recess, is designed in 3 different sizes. In the preferred embodiment, a first size is suitable for M6x20 nuts and screws, while the other two sizes have different widths and cable channel 14 configurations and are suitable for M12x35 nuts and screws.
[0088] exist Figure 6 and 7 In the embodiment shown, the cover box 10 comprises two safety walls 18 extending vertically on both sides of its latching devices 16, 17. Each safety wall 18 comprises a first and a second portion 181, 182, the first half shell 11 comprises the first portion 181, the second half shell 12 comprises the second portion 182, and when the first and second half shells 11, 12 are assembled, the two portions of each safety wall 18 define an extension of each other.
[0089] Figure 8 A possible embodiment is shown in which the two annular tongues 3 at the ends of the two cables 4 are accommodated by the cover box 10. Here, the electrical connector 1 also comprises two thin sheets: one between the nut 51 and the first annular tongue 3, and the other between the screw head 52 and the second annular tongue 3. The rod 2 is sandwiched between the two annular tongues 3. This embodiment shows that the dimensions of the recesses 15 are designed to perform their blocking function with different electrical connector 1 configurations. Figure 1 In the embodiment, when an annular tongue 3 is used, a gap is left between the edge of the recess 15 and the sheet, but the nut 51 is still partially accommodated in the recess and the blocking function is achieved, while in Figure 7 In the embodiment, two annular tongues 3 are used, the nut 51 is completely accommodated without any gap, and the blocking function is also achieved.
