Description

Technical Field

[0001] This utility model relates to the field of connector technology for electrical installation, and in particular to a convenient installation device. Background Technology

[0002] The installation of wall-mounted electrical appliances (such as fans and light fixtures) has always been a headache. Installing appliances requires both supporting their weight and simultaneously wiring them, increasing both the difficulty and the potential danger.

[0003] Therefore, how to develop a practical lighting connector with a reasonable structural design, quick and safe connection, and convenient disassembly and maintenance is a technical problem that the industry urgently needs to solve. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a convenient installation device that can quickly install electrical appliances such as lamps, and has a locking function to effectively prevent the lamps and other electrical appliances from loosening and falling.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a convenient installation device, comprising a plug for connecting an external electrical appliance and a socket for connecting an external power line, wherein the plug and the socket are detachably connected and the plug is used for electrical connection with the socket to fix the external electrical appliance and conduct electricity to the external power line; the socket is provided with an elongated hole, the elongated hole having a first region and a second region along its length; in the orthographic projection of the horizontal plane of the elongated hole, the first region is wider than the second region; a locking groove is provided on one side wall of the second region; the plug is provided with a locking member, the locking member being able to extend and retract from the side of the plug; in its natural state, the locking member extends from the side of the plug; when subjected to a force toward the plug, the locking member retracts toward the plug; after the force disappears, the locking member extends from the side of the plug; the first region allows at least part of the locking member to extend into; when the locking member moves from the first region into the second region, it retracts due to the width of the second region until it moves to align with the locking groove and extends into the locking groove.

[0006] By connecting the plug to the appliance and the socket to the power line, the appliance can be installed and powered on simply by plugging the plug into the socket. This is convenient and quick. The design also includes a locking mechanism and a locking groove. The locking mechanism and locking groove work together to prevent the plug from loosening after being plugged into the socket, effectively preventing the plug from detaching from the socket and the appliance from falling off. Assembly is simple; just move the locking mechanism into the locking groove without any additional installation steps. Disassembly is quick and easy; simply press the locking mechanism to disengage it from the locking groove before disassembling.

[0007] Preferably, the plug is provided with a lug, the first region allows the lug to pass through, and when the locking member extends into the locking groove, the edge of the second region restricts the lug from passing through the elongated hole.

[0008] The hook-on design, which overlaps the upper edge of the second area, prevents the plug from sliding downwards, effectively enhancing the stability of the plug connection to the socket.

[0009] Preferably, the locking member has a limiting groove on the side wall facing the locking groove. The limiting groove is L-shaped and located on the top surface of the locking member. The hook is located above the locking member. When the locking member extends into the locking groove, the bottom surface of the limiting groove and the hook clamp the edge of the locking groove.

[0010] The design of the interlocking locking groove edge formed by the engagement of the hook and the limiting groove restricts the up-and-down movement of the plug, further ensuring the stability of the plug after it is connected to the socket. It should be noted that "interlocking" does not mean that the locking groove edge is completely locked; a certain amount of up-and-down movement is allowed to facilitate installation and alignment.

[0011] Preferably, the plug includes a bracket and a male connector. The bracket includes a base and a vertical portion connected to the base. The lug is disposed on the vertical portion and extends in the direction of the extension of the locking member. The vertical portion is provided with a telescopic hole located below the lug. The locking member is disposed on the male connector, and the telescopic hole is used for the locking member to pass through.

[0012] The vertical design of the bracket places the hanging ears and the locking mechanism on the same vertical line. The hanging ears provide some protection for the locking mechanism, preventing accidental impact during plug-socket connection. Damage to the locking mechanism could prevent it from extending and retracting properly, thus causing the locking function to fail.

[0013] Preferably, the male connector is provided with a first cavity and a first elastic member located in the first cavity. The first cavity has a first opening communicating with the outside. The locking member extends out from the first opening. One end of the first elastic member abuts against the locking member, and the other end of the first elastic member abuts against the bottom wall of the first cavity. The first cavity is provided with travel grooves on both sides. The portion of the locking member located in the first cavity is provided with a protrusion corresponding to the travel groove.

[0014] The engagement of the travel groove and the protrusion of the locking element restricts the forward and backward movement of the locking element, preventing it from completely disengaging from the male connector. The first elastic element is preferably a spring, which enables the extension and retraction of the locking element.

[0015] Preferably, the elongated hole is arc-shaped, and when the plug is connected to the socket, the locking member slides from the first area into the second area and extends into the locking groove by rotating the plug.

[0016] The elongated hole is designed to be arc-shaped. After the plug is connected to the socket, rotating the plug will allow the locking part to extend into the locking groove. The operation steps are simple and the installation difficulty is low.

[0017] Preferably, the socket includes a mounting plate and a female connector. The mounting plate is provided with a mating hole. The female connector is mounted on the mounting plate and the position of the female connector for electrical connection with the plug is aligned with the mating hole. The elongated hole is provided on the mounting plate.

[0018] The mounting plate and the female terminal block are combined to form a socket. The mounting plate structure is easy to use with other mounting parts and to install the female terminal block to the wall or ceiling.

[0019] Preferably, the female terminal block is provided with a second cavity and a conductive sheet partially located in the second cavity. The second cavity has a second opening and a third opening communicating with the outside of the female terminal block. The second cavity is provided with a wrench, a pressing spring, and a first shaft. The pressing spring is U-shaped and sleeved on the first shaft. The wrench is L-shaped and has a second shaft in the middle. One end of the wrench extends out from the second opening. When the wrench rotates along the second shaft, the inner end of the wrench pushes the pressing spring to rotate along the first shaft, causing one end of the pressing spring to move closer to the conductive sheet and press the wire inserted from the third opening onto the conductive sheet.

[0020] The design, including the wrench, allows operators to easily connect the wires to the female terminal block, making the operation convenient and quick.

[0021] Preferably, the female connector is provided with a third cavity and a second elastic member located in the third cavity. The third cavity has a fourth opening communicating with the outside. A portion of the conductive sheet is located in the third cavity. One end of the second elastic member abuts against the conductive sheet, and the other end abuts against the inner wall of the third cavity, so that the conductive sheet abuts against the plug inserted into the fourth opening.

[0022] The second elastic element is preferably a spring. When the plug is connected to the socket, the spring abuts against the conductive plate, and the conductive plate is pressed against the conductive plate of the male terminal block by the spring, thereby enhancing the conductivity stability.

[0023] Preferably, the socket has a circular socket, the plug has a circular insertion portion corresponding to the circular socket, and the plug can rotate relative to the socket after being connected to it.

[0024] It adopts a round socket and round plug design, and the two can be locked and installed by inserting and rotating when they are connected.

[0025] Preferably, the second region has a slope at one end near the first region, and the slope is used to abut against the locking member;

[0026] The locking groove has a flat surface at one end near the first region, and the flat surface is used to engage with the locking member.

[0027] Preferably, the plug further includes a housing, a grounding conductive post, and a compression spring. The housing has a fourth cavity for accommodating the grounding conductive post. One end of the compression spring is connected to the grounding conductive post, and the other end is connected to the housing to drive the grounding conductive post out of the cavity.

[0028] After the plug is connected to the socket, the grounding conductive post abuts against the socket, and the compression spring is compressed. Attached Figure Description

[0039] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0040] like Figure 1 As shown, a convenient installation device includes a plug 1 for connecting an external electrical appliance and a socket 2 for connecting an external power line. The plug 1 is detachably connected to the socket 2 and is used for electrical connection with the socket 2 to fix the external electrical appliance and conduct electricity through the external power line.

[0041] The socket 2 includes a mounting plate 3 and a female connector 4 fixed to the mounting plate 3 with screws. The mounting plate 3 has an arc-shaped elongated hole 31 and other fixing holes 34, through which the socket 2 is fixed to the wall or ceiling. The plug 1 includes a bracket 5 and a male connector 6 fixed to the bracket 5 with screws. The bracket 5 is designed to match the connection position of the appliance, thereby fixing the plug 1 to the appliance. During installation, the plug 1 on the appliance is aligned with the socket 2 on the wall or ceiling and inserted. The appliance is then rotated at a certain angle, causing the plug 1 to rotate relative to the socket 2 at a certain angle to complete the installation.

[0042] like Figures 2 to 4 As shown, the female connector 4 is fixed to the mounting plate 3 by screws. The mounting plate 3 is a circular plate with a certain thickness and has a mating hole 32. After the female connector 4 is fixed to the mounting plate 3, the circular socket 41 of the female connector 4 is aligned with the mating hole 32. When the plug 1 is connected to the socket 2, the circular plug part 61 of the plug 1 passes through the mating hole 32 and is inserted into the circular socket 41, thereby allowing the conductive piece 11 of the plug 1 to contact and conduct electricity with the conductive piece 21 of the socket 2. The mounting plate 3 is also provided with two arc-shaped elongated holes 31, which are located on both sides of the mating hole 32 and are arranged opposite each other. The arc-shaped elongated holes 31 have a first region 311 and a second region 312. In the orthographic projection of the elongated hole 31 on the horizontal plane, the first region 311 is wider than the second region 312. The width is the width between the two long sides of the arc-shaped elongated hole 31. The hole wall of the second region 312 is provided with a locking groove 33. Specifically, the locking groove 33 is located on the side of the second region 312.

[0043] like Figure 3As shown, the female terminal block 4 includes a housing 42, which has a cavity 44 for accommodating two conductive wire lockers 43. A conductive piece 21 is fixed on the conductive wire locker 43. The housing 42 has three openings communicating with the cavity 44, two of which, 45 and 46, correspond to the conductive wire lockers 43. The remaining opening is located on the bottom surface of the housing 42 and is designed as a circular socket 41. One end of the conductive piece 21 is fixed by the conductive wire locker 43 for contacting and conducting electricity with the inserted wire. The other end of the conductive piece 21 extends to the circular socket 41 and protrudes. The housing 42 is also connected to a sealing cover 47 for covering the cavity 44.

[0044] like Figures 9 to 10 As shown, in some other embodiments, the female terminal block 4 does not use the conductive wire lock 43 design. Instead, it uses a structure such as a wrench 7 to press the inserted wire to ensure stable conductivity between the conductive piece 75 and the wire. Specifically, the outer shell 74 of the female terminal block 4 is provided with a cavity 76 for installing the conductive piece 75. The outer shell 74 is provided with two openings 77 for inserting power supply lines, two openings 78 for partially exposing the wrench 7, and a circular socket 41 located on the bottom surface of the outer shell. One end of the conductive piece 75 is exposed in the circular socket 41, and the other end of the conductive piece 75 is exposed in the power supply line socket. The cavity 76 contains an opening 77, a wrench 7, a pressing spring 71, and a first shaft 72. The pressing spring 71 is U-shaped and sleeved on the first shaft 72. The wrench 7 is L-shaped and has a second shaft 73 in the middle. One end of the wrench 7 extends out from the corresponding opening 78. By pressing the end 79 of the wrench 7 exposed from the opening 78, the wrench 7 rotates along the second shaft 73. The inner end 70 of the wrench 7 pushes the pressing spring 71 to rotate along the first shaft 72, causing one end of the pressing spring 71 to move closer to the conductive plate 75 and press the wire inserted from the opening 77 onto the conductive plate 75, thereby effectively ensuring stable conductivity.

[0045] like Figures 9 to 10 As shown, in some other embodiments, a spring 711 can be added between the conductive sheet 75 and the inner wall of the cavity 76 in the female terminal block 4. The spring 711 provides a force to the conductive sheet 75 toward the circular socket 41 so that the conductive sheet 75 can better contact and conduct with the conductive sheet 11 on the plug 1.

[0046] like Figures 5 to 6As shown, the male connector 6 is fixed to the bracket 5 by screws. The bracket 5 consists of a base 51 and a vertical part 52 extending from the base 51. The vertical part 52 has two parts located on both sides of the base 51 and facing each other. The free end of the vertical part 52 has a lug 53, which extends in the direction of the extension of the locking member 62. The vertical part 52 also has a telescopic hole 54 located below the lug 53. The locking member 62 is installed on the male connector 6. The male connector 6 is installed on the base 51 and the locking member 62 is aligned with the telescopic hole 54 of the vertical part 52. The locking member 62 extends and retracts by passing through the telescopic hole 54.

[0047] like Figure 6 As shown, the male terminal block 6 includes a housing 63. The housing 63 has two cavities 65 for accommodating two conductive locking devices 64, two cavities 66 for accommodating two locking elements 62, and a cavity 68 for accommodating a grounding conductive post 67. The male terminal block also includes a compression spring 617, which can be located inside the cavity 68. One end of the compression spring 617 is connected to the grounding conductive post 67, and the other end is connected to the housing 63, to drive the grounding conductive post 67 out of the cavity 68. After the male terminal block 6 is connected to the female terminal block 4, the conductive post 67 abuts against the mounting plate 3. The mounting plate 3 forces the conductive post 67 back into the cavity 68, and the compression spring 617 is compressed. The compression spring 617 applies force to the conductive post 67 to increase the pressure between the grounding conductive post 67 and the mounting plate 3, thereby reducing the contact resistance between the grounding conductive post 67 and the mounting plate 3. The outer casing 63 is also provided with three openings in the cavity 65 of the conductive wire lock device 64. Two of the openings 69 and 60 are respectively used to accommodate the two cavities 65 of the conductive wire lock device 64 for inserting and connecting the wire to the conductive piece 11 on the conductive wire lock device 65. The remaining opening is located at the circular plug-in portion 61 on the top surface of the outer casing. The conductive piece 11 fixed by the conductive wire lock device 65 extends to the circular plug-in portion 61 and is exposed through the opening so that when the circular plug-in portion 61 is connected to the circular socket 41, the conductive piece 11 of the circular plug-in portion 61 and the conductive piece 21 of the circular socket 41 make contact and conduction.

[0048] like Figure 6 As shown, the outer shell 63 is also provided with two cavities 66 corresponding to the two locking members 62 respectively. The cavity 66 has an opening 611. A spring 612 is provided inside the cavity 66. One end of the spring 612 abuts against the locking member 62, and the other end of the spring 612 abuts against the bottom wall of the cavity 66, so that the locking member 62 can extend and retract along the direction of the opening 611. The two sides of the cavity 66 are provided with stroke grooves 613. The part of the locking member 62 located in the cavity 66 is provided with a protrusion 614 corresponding to the stroke groove 613. When the locking member 62 moves back and forth along the direction of the opening 611 of the cavity 66, the cooperation between the protrusion 614 and the stroke groove 613 prevents the locking member 62 from completely disengaging from the opening 611.

[0049] like Figures 5 to 7 As shown, the locking member 62 has a limiting groove 616 on its side wall 615 facing the locking groove 33. The limiting groove 616 is located at the top of the locking member 62 and is L-shaped, extending to the top surface of the locking member 62. When the locking member 62 extends into the locking groove 33, the bottom surface of the limiting groove 616 can abut against the lower edge of the locking groove 33. At the same time, the hook 53 overlaps the upper edge of the locking groove 33. That is, the bottom wall of the limiting groove 616 and the hook 53 together clamp the edge of the locking groove 33. The hook 53 and the limiting groove 616 of the locking member 62 engage with the edge of the locking groove 33, effectively restricting the up and down movement of the plug 1. The simple structure enhances the stability of the plug 1 after it is connected to the socket 2. It should be noted that the engagement with the edge of the locking groove 33 is not completely tight, and a certain amount of vertical floating space is allowed to facilitate installation and alignment.

[0050] like Figure 1 and 8 As shown, the installation process of plug 1 and socket 2 involves the female connector 4 being fixed to the mounting plate 3 with screws. The mounting plate 3 is then fixed to the wall or ceiling via its other fixing holes 34 and screws. The male connector 6 is fixed to the bracket 5 with screws. The bracket 5 is then fixed to the appliance with screws. The male connector 6 on the appliance is aligned with the female connector 4 on the wall or ceiling and inserted. At this point, the round plug portion 61 of the male connector 6 is inserted into the round socket 41 of the female connector 4, and the vertical portion 52 of the bracket 5 extends into the first area 311 of the arc-shaped elongated hole 31 of the mounting plate 3. 1. The lug 53 located at the free end of the vertical part 52 passes through the first area 311 and is positioned above the hanging plate 3. The telescopic hole 54 of the vertical part 52 is at least partially aligned with the hole wall of the first area 311, thereby aligning the limiting groove 616 of the locking member 62 with the hole wall of the first area 311. After the insertion is completed, the electrical appliance is rotated to make the male terminal 6 rotate relative to the female terminal 4. The rotation of the male terminal 6 causes the locking member 62 and the lug 53 to move into the second area 312. The locking member 62 aligns with the locking groove 33 and extends in. The lug 53 overlaps the upper edge of the second area 312, i.e., the locking groove 33, to complete the locking and fixing installation. During disassembly, the two locking parts 62 need to be manually pressed to disengage them from the locking groove 33. Then, rotate them in the opposite direction to allow the locking parts 62 and the lugs 53 to enter the first area 311 from the second area 312. Pull the locking parts 62 and the lugs 53 in a direction perpendicular to the direction of rotation to disengage them from the first area 311 and disengage the plug 1 from the socket 2.

[0051] In the first region 311 and the second region 312 of the mounting plate 3, the wider first region 311 allows the locking member 62 and the hanging ear 53 on the plug 1 to pass through, while the narrower second region 312 causes the locking member 62 to retract until it aligns with the locking groove 33 before extending again to achieve a locking effect. Simultaneously, the narrower second region 312 can, to a certain extent, clamp the vertical part 52 on the bracket 5, and also allows the hanging ear 53 to have an overlapping position, greatly enhancing the connection stability after the plug 1 is connected to the socket 2. Specifically, as... Figure 2 and Figure 4 As shown, the second region 312 has a ramp 3111 at one end 311 near the first region 311. The ramp 3111 is used to abut against the locking member 62 so that the locking member 62 automatically retracts during the process of moving from the first region 311 to the second region 312. The locking groove 33 has a flat surface 331 at one end near the first region 311. The flat surface 331 is used to engage with the locking member 62 to restrict the retraction of the locking member 62, so that the locking member 62 cannot automatically retract after entering the locking groove 33, thereby restricting the locking member 62 from automatically entering the first region 311 from the second region 312.
