Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a circuit installation structure, a wire-locking heat dissipation cover plate, and an electrical component. Background Technology

[0002] In existing technologies, the installation of power cords for common electrical appliances such as lamps typically relies on a relatively complex structure and the coordination of multiple components. Specifically, to ensure the power cord is securely fixed to the lamp housing, additional parts are often required, such as wire clips or wire clamps, which are then fastened to the lamp housing with screws to secure the power cord. While this design can meet basic usage requirements to some extent, it also complicates the overall wiring structure of the appliance, increasing the manufacturing process and raising production costs due to the various components. Furthermore, the complex installation process extends the product assembly time.

[0003] On the other hand, existing wiring installation methods cannot simultaneously achieve the functions of easy wire insertion and wire clamping. Using wire clamps or wire clamps and fastening these parts to the lamp housing with screws provides good wire clamping, but wire insertion is not easy and involves many installation steps. On the other hand, directly setting up wire channels for wire entry and exit makes wire insertion easy, but wire clamping is not secure and can easily lead to problems such as poor contact due to insufficient fixation.

[0004] Therefore, how to simplify the wiring installation structure of electrical appliances, especially lighting fixtures, reduce costs, and at the same time effectively improve the convenience of wiring installation and the reliability of wiring has become an urgent technical problem to be solved. Utility Model Content

[0005] The main purpose of this utility model is to propose a line installation structure that combines easy line installation and wire clamping functions through a simple and compact structure. This aims to solve the technical problem that existing technologies use complex line installation structures to fix lines without simultaneously achieving easy line installation and wire clamping functions.

[0006] The secondary objective of this utility model is to propose a wire-locking heat dissipation cover plate that integrates the circuit installation structure with the existing heat dissipation structure, thereby greatly improving the stability of the wire-locking.

[0007] The third objective of this utility model is to provide an electrical appliance that utilizes the aforementioned wiring mounting structure or wire-blocking heat dissipation cover.

[0008] To achieve the above objectives, this utility model proposes a circuit mounting structure, including a substrate and a wire groove disposed on the substrate. The wire groove has an inner cavity with an inlet end and an outlet end. An elastic wire pressing member is integrally formed on the inner wall of the wire groove. The elastic wire pressing member has a connecting part and a wire pressing structure protruding into the inner cavity. The connecting part is connected to the inner wall of the wire groove and the wire pressing structure.

[0009] The inner wall of the groove is provided with a movable slot that provides deformation space for the elastic pressure member. The movable slot has an opening facing the inner cavity, and the elastic pressure member is located in the movable slot or in front of the movable slot.

[0010] This invention features a wire-pressing structure that, during wire insertion, deforms the wire into the cable tray, facilitating insertion. Simultaneously, the protruding pressure structure of the elastic pressure member has a clamping tendency towards the inner cavity, ensuring the wire is securely held in place and difficult to move. This invention boasts a compact and simple structure, saves on steps, and is easy to install. It eliminates the need for existing pressure plates and screws, while simultaneously providing convenient wire insertion and clamping functions. It can be widely applied to the installation of common electrical wiring, such as power cords, enabling the clamping and installation of different types and specifications of wiring, and has promising market prospects.

[0011] Preferably, the elastic pressure line is made of a known elastic plastic material.

[0012] Preferably, an integrally formed fixing pressure member is provided on the inner wall of the wire groove, opposite to the elastic pressure member. The fixing pressure member has a pressure structure protruding into the inner cavity. The opposing fixing pressure member and the elastic pressure member form a surrounding fixation of the wire, resulting in better fixation performance.

[0013] Preferably, the wire clamping structure has a toothed design. This toothed design facilitates the engagement of the power cord, further improving stability.

[0014] Preferably, the wire clamping structure has a beveled guide or curved guide near the wire entry end to guide the wire in. This preferred embodiment facilitates the wire passing through the wire cavity along the beveled guide or curved guide, thus facilitating wire entry.

[0015] This utility model also provides a wire-locking heat dissipation cover plate, including the line mounting structure of any of the aforementioned solutions, and a heat dissipation module located on the substrate, wherein the heat dissipation module is snapped onto the substrate.

[0016] The wire groove protrudes from the substrate, the movable slot is disposed through the inner wall of the wire groove, the elastic wire pressing member is located in the movable slot, and the outer side of the elastic wire pressing member away from the inner cavity is flush with the outer wall of the wire groove, with the outer side of the elastic wire pressing member away from the inner cavity as the abutting side.

[0017] The bottom height of the elastic pressure wire component is higher than the horizontal height of the substrate. The substrate has a boss near the abutting side. The side of the boss facing the wire groove, the abutting side and the top surface of the substrate in the middle are connected to form a first snap-fit ​​groove. The heat dissipation module has a snap-fit ​​part that fits into the first snap-fit ​​groove.

[0018] When the snap-fit ​​part and the first snap-fit ​​groove are engaged, the snap-fit ​​part abuts against the abutting side.

[0019] This solution improves the structure of existing heat dissipation covers to create a cable-locking heat dissipation cover, combining heat dissipation and cable-locking functions after installation. Taking power cord installation as an example, during installation, the power cord is first inserted into the cable groove. At this time, the elastic wire-pressing component is squeezed and deforms outward through the movable slot. Then, the heat dissipation module is aligned and fitted into the first locking slot, completing the installation of the power cord and the heat dissipation module. In this utility model, the cable-locking heat dissipation cover, due to the abutment of the locking part on the contact side, causes the elastic wire-pressing component to be squeezed into the inner cavity. Under the squeezing action, the power cord is further tightened, forming a double fixation for the power cord. While facilitating wire insertion, it greatly improves the reliability of the wire fixation. Even when subjected to external force, the power cord is difficult to loosen.

[0020] Preferably, the substrate forming the first snap-fit ​​groove has a pre-reserved clearance groove that communicates with the movable slot. This allows for more deformation space to be provided for the elastic pressure wire component.

[0021] In another preferred embodiment, the boss includes a first boss and a second boss that are relatively separated. Adjacent sides of the first and second bosses connect to the top surface of the substrate located in the middle to form a second snap-fit ​​groove. The first and second snap-fit ​​grooves communicate to form a T-shaped through groove, and the shape of the snap-fit ​​portion matches the T-shaped through groove. This improves the stability of the heat dissipation module installation.

[0022] This utility model also provides an electrical appliance with a wiring installation structure as described in any of the aforementioned schemes, or with a wire-blocking heat dissipation cover as described in any of the aforementioned schemes. It possesses all the beneficial effects of the aforementioned technical solutions, which will not be elaborated upon here.

[0023] A specific electrical implementation is provided, wherein the electrical appliance is a lamp, the lamp is provided with a heat dissipation cover for wire clamping of any of the aforementioned schemes, and the lamp also includes a light source, a power cord, a power driver, a reflector and a housing component;

[0024] The rear cover and the housing components are connected to form the inner cavity of the lamp. The power driver is connected to the light source. The reflector is installed in the inner cavity of the lamp. The light source is fixed above the light source hole on the top of the reflector. The power cord enters the inner cavity of the lamp through the wire groove and is connected to the power driver so that the power driver can provide the required power to the light source.

[0036] This application proposes a line installation structure 11, such as Figures 1-2 As shown, the device includes a substrate 111 and a wire groove 112 disposed on the substrate 111. The wire groove 112 has an inner cavity 1121, an inlet end 1122 and an outlet end 1123. An elastic wire pressing member 11242 is integrally formed on the inner wall 1124 of the wire groove. The elastic wire pressing member 11242 has a connecting part and a wire pressing structure 11244 protruding into the inner cavity 1121. The connecting part is connected to the inner wall 1124 of the wire groove and the wire pressing structure 11244.

[0037] The inner wall 1124 of the wire groove is provided with a movable slot 11241 that provides deformation space for the elastic pressure member 11242. The movable slot 11241 has an opening facing the inner cavity 1121. The elastic pressure member 11242 is located in the movable slot 11241 or in front of the movable slot 11241.

[0038] In this invention, when the line is installed, the line entering the trough 112 is squeezed and pressed by the wire pressing structure 11244 and deformed in the direction away from the inner cavity 1121 to facilitate the insertion of the line. At the same time, the protruding pressing structure 11244 of the elastic pressing member 11242 has a fastening tendency towards the inner cavity 1121, so that the line is clamped and not easy to move.

[0039] The wire pressing structure 11244 protruding into the inner cavity 1121 of the elastic wire pressing member 11242 should be designed to allow the wire entering the wire groove 112 to pass through, and to cause the elastic wire pressing member 11242 to undergo appropriate compression deformation towards the movable slot 11241. It is necessary to avoid two situations: the protrusion is too large, making it difficult for the wire to pass through the wire groove 112, and the protrusion is too small, resulting in insufficient compression deformation of the elastic wire pressing member 11242, which would prevent the wire from being fixed.

[0040] The movable slot 11241 provides space for the elastic pressure member 11242 to deform. Structurally, it can be a through slot on the wire groove 112, a semi-through slot with the outer wall of the wire groove 112 closed and the inner wall 1124 open, or other structural forms that can also achieve the provision of space for the elastic pressure member 11242 to deform in existing disclosed slot designs, all of which fall within the scope of this movable slot 11241.

[0041] In a preferred embodiment, such as Figures 1-2 As shown, an integrally formed fixing wire clamping member 11243 is disposed on the inner wall 1124 of the wire groove opposite to the elastic wire clamping member 11242. The fixing wire clamping member 11243 has a wire clamping structure 11244 protruding into the inner cavity 1121. The opposing fixing wire clamping member 11243 and the elastic wire clamping member 11242 surround and fix the wire. In a further preferred embodiment, the wire clamping structure 11244 has a toothed design. This toothed design facilitates the engagement of the power wire 3.

[0042] In another preferred embodiment, such as Figures 1-2 As shown, the wire clamping structure 11244 is provided with a sloping guide portion 11245a or a curved guide portion 11245b (not shown in the figure) near the wire entry end 1122 for guiding the wire entry. This preferred embodiment facilitates the wire to pass through the wire cavity along the sloping guide portion 11245a or the curved guide portion 11245b, thus facilitating wire entry.

[0043] This application also provides a heat dissipation cover 1 for a cable, such as Figures 1-4 As shown, it includes the circuit mounting structure 11 in any of the aforementioned schemes, and the heat dissipation module 15 located on the substrate 111, the heat dissipation module 15 being snapped onto the substrate 111.

[0044] A wire groove 112 protrudes from the substrate 111, and a movable slot 11241 penetrates the inner wall 1124 of the wire groove. An elastic wire pressing member 11242 is located within the movable slot 11241, and the outer surface of the elastic wire pressing member 11242 facing away from the inner cavity 1121 is flush with the outer wall of the wire groove 112. Figure 2As shown, the outer side of the elastic pressure wire member 11242 that is opposite to the inner cavity 1121 is the abutting side 113;

[0045] like Figure 2 As shown, the bottom height of the elastic pressure wire member 11242 is higher than the horizontal height of the substrate 111. The substrate 111 has a boss 12 near the abutment side 113. The side of the boss 12 facing the wire groove 112, the abutment side 113 and the top surface of the substrate 111 located in the middle are connected to form a first snap-fit ​​groove 13. The heat dissipation module 15 has a snap-fit ​​part 151 that is engaged and snap-fitted with the first snap-fit ​​groove 13.

[0046] When the snap-fit ​​portion 151 engages with the first snap-fit ​​groove 13, the snap-fit ​​portion 151 presses against the abutment side 113, such as Figures 1-4 As shown.

[0047] Taking the installation of power cord 3 as an example, during installation, power cord 3 is first inserted into the wire groove 112. At this time, the elastic wire pressing member 11242 is squeezed and deforms outward through the movable slot 11241. Then, the heat dissipation module 15 is aligned and fitted into the first snap-fit ​​slot 13, completing the installation of power cord 3 and heat dissipation module 15. In the wire-clamping heat dissipation cover 1 of this utility model, during installation, the abutting side 113 is abutted by the snap-fit ​​part 151, causing the elastic wire pressing member 11242 to be squeezed into the inner cavity 1121. Under the squeezing action, the power cord 3 is further compressed, forming a double fixation for the power cord 3.

[0048] In a preferred embodiment, such as Figures 1-2 As shown, the substrate 111 forming the first snap-fit ​​groove 13 has a clearance groove 1111 that communicates with the movable slot 11241. This is beneficial for reserving more deformation space for the elastic pressure wire member 11242.

[0049] In a preferred embodiment, such as Figures 1-2 As shown, a chamfer 1201 is provided on the boss 12 to facilitate the entry of the snap-fit ​​part 151.

[0050] In another preferred method, such as Figures 1-4 As shown, the boss 12 includes a first boss 121 and a second boss 122 that are relatively separated. The adjacent side surfaces between the first boss 121 and the second boss 122 are connected to the top surface of the substrate 111 located in the middle to form a second snap-fit ​​groove 14. The first snap-fit ​​groove 13 and the second snap-fit ​​groove 14 communicate to form a T-shaped through groove. The shape of the snap-fit ​​part 151 matches the T-shaped through groove. This improves the stability of the heat dissipation module 15 during installation.

[0051] In a preferred embodiment, such as Figures 3-4As shown, the heat dissipation module 15 is arranged in a plurality of radial structures and is snapped into a T-shaped through slot. The wire groove 112 is located at the end of one of the radial structures of the heat dissipation module 15 at the position of the substrate 111. The overall shape of the wire-slotted heat dissipation cover 1 is more aesthetically pleasing. In one specific embodiment, the radial structure is snowflake-shaped.

[0052] This application also provides an electrical appliance equipped with a wiring installation structure 11 as described in any of the foregoing schemes, or equipped with a wire-blocking heat dissipation cover 1 as described in any of the foregoing schemes. It possesses all the beneficial effects of the foregoing technical solutions, which will not be elaborated upon here.

[0053] Provide a specific embodiment, such as Figures 4-5 As shown, the electrical appliance is a lamp, which is equipped with a heat dissipation cover 1 for wire clamping of any of the aforementioned schemes. The lamp also includes a light source 2, a power cord 3, a power driver 4 (not shown in the figure), a reflector 5, and a housing component 6.

[0054] The rear cover 8 is connected to the housing component 6 to form the lamp cavity 7. The power drive 4 is connected to the light source 2. The reflector cup 5 is installed in the lamp cavity 7. The light source 2 is fixed on the upper part of the light source 2 hole at the top of the reflector cup 5. The power cord 3 enters the lamp cavity 7 through the wire groove 112 and is connected to the power drive 4 so that the power drive 4 provides the required power to the light source 2.

[0055] In some specific embodiments, the power cord is a sheathed cord.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
