Description

Technical Field

[0001] This utility model relates to the field of lamp wire clamping technology, and in particular to a lamp wire clamping structure and a lamp. Background Technology

[0002] Currently, most recessed lighting fixtures on the market use a top-and-bottom clamping method for their power cords. However, this method provides limited clamping space and allows for very little room for bending the wires, making it prone to loosening and failing to meet the safety requirements for push-pull protection of power cords, thus posing a safety hazard. Therefore, this application aims to provide a clamping structure for recessed lighting fixtures to address the shortcomings of existing top-and-bottom clamping methods. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a lighting fixture wire pressing structure and a lighting fixture, aiming to solve at least one or more technical problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides a wire clamping structure for a lighting fixture, wherein the lighting fixture includes a lamp body and an insulating shell installed inside the lamp body. The insulating shell has a latch for guiding a power cord. The wire clamping structure is installed into the latch to attach the power cord to the insulating shell. The wire clamping structure includes: a wire clamping clip, including a wire clamping portion removably attached to the latch, the wire clamping portion having a first wire clamping groove on one side facing the power cord and a first protrusion on the other side; and a wire clamping clip, detachably engaged with the wire clamping clip, having a second wire clamping groove facing the first wire clamping groove and a second protrusion on the other side facing away from the second wire clamping groove. When the wire clamping clip and the wire clamping clip remain engaged, the first wire clamping groove and the second wire clamping groove surround the power cord relative to each other, such that the first protrusion and the second protrusion at least partially abut against and jointly clamp the power cord.

[0005] Preferably, the side of the first protrusion facing the power cord has a first locking block that can abut against the power cord, and the side of the second protrusion opposite the first protrusion facing the power cord has a second locking block that can abut against the power cord. In this application, based on the first and second protrusions that can cooperate with each other to radially surround the power cord and define the movement space of the power cord, this application restricts the movement of the power cord by using the first and second locking blocks that can abut against the power cord relative to each other. Specifically, by abutting the first and second locking blocks radially against the circumferential side of the power cord, radial pressure is applied to the outer periphery of the power cord in at least two opposing directions, thereby increasing the contact friction between the protrusions and the power cord, thus achieving the purpose of restricting the vertical and horizontal movement of the power cord.

[0006] Preferably, the end faces of the first and second locking blocks facing the power cord are respectively provided with locking portions that can engage with the power cord based on the engagement of the wire clamp and the wire pressure clip to restrict its movement. In addition to applying radial pressure to the power cord by the first and second locking blocks radially abutting against it, this application further provides locking portions at the end faces of the two opposing locking blocks that contact the power cord, allowing them to adapt to the outer contour of the power cord and engage with it. These locking portions have a bayonet structure whose shape is adapted to the power cord to at least partially surround the power cord from the radial outside. This bayonet structure restricts the lateral movement of the power cord, and the contact friction between the two further prevents the power cord from twisting or sliding vertically.

[0007] Preferably, the wire clip further includes fixing portions arranged on both sides of the wire clamping portion, at least a portion of which is configured as an inclined surface capable of partially or completely engaging with the wire clamp. In this application, an inclined surface structure capable of partially or completely engaging the fixing portion with the wire clamp is constructed on the side of the fixing portion that contacts the wire clamp. Similar to a foolproof design, this inclined surface structure allows installers to easily and quickly align the wire clamp and the wire clip together, thereby quickly assembling them; at the same time, this inclined surface structure also increases the tightness of the connection between the wire clamp and the wire clamp.

[0008] Preferably, the second cable clamping groove has sliding ribs on both sides that point towards the inclined surface and adapt to the inclined surface. By providing sliding ribs on the cable clamp that adapt to the inclined surface of the cable clamp, when the cable clamp and the cable clamp are pressed together along the extension direction of the power cord, the sliding ribs can adapt to the inclined surface of the cable clamp to slide, allowing the cable clamp to move synchronously in the direction closer to the power cord. This further presses the cable clamp surface against the clamping block and the locking portion of the power cord end face, thereby increasing the clamping force applied to the power cord.

[0009] Preferably, the fixing part has a first fixing hole for locking in the first fastener, and the wire clip has a second fixing hole corresponding to the first fixing hole to allow the first fastener to pass through.

[0010] Preferably, when the wire clip and the wire clamp are secured by the first fastener, the first boss and the second boss together form a receiving hole for restricting the power cord.

[0011] Preferably, the projection of the first locking block along the axial direction of the lighting fixture is partially or entirely located within the first wire-locking groove, and the projection of the second locking block along the axial direction of the lighting fixture is partially or entirely located within the second wire-locking groove. Based on the fact that the first and second wire-locking grooves surround the power cord relative to each other to define the radial movement space of the power cord, when the projections of the first and second locking blocks along the axial direction of the lighting fixture are partially or entirely located within their respective corresponding wire-locking grooves, the radial movement space of the power cord between the first and second wire-locking grooves is further restricted by the first and second locking blocks, thereby making the power cord more securely fixed.

[0012] Preferably, with the wire clip and the wire clamp engaged, the first wire clip groove and the second wire clip groove partially or completely overlap along the axial direction of the lighting fixture.

[0013] Preferably, the second aspect of this utility model also relates to a lighting fixture, which includes the lighting fixture wire pressing structure described in this utility model.

[0014] The beneficial technical effects of this utility model include:

[0015] This utility model provides a lighting fixture wire clamping structure, including a wire-locking clip and a wire-pressing clip combined with each other. The wire-locking clip has a first wire-locking groove and a first protrusion, and the wire-pressing clip has a second wire-locking groove and a second protrusion. When the wire-pressing clip is assembled onto the surface of the wire-locking clip, the first wire-locking groove and the second wire-locking groove circumferentially surround the power cord, while the first and second protrusions at least partially abut against and jointly clamp the power cord. According to the lighting fixture wire clamping structure provided by this utility model, this wire clamping structure increases the power cord clamping method for cylindrical lighting fixtures, making the power cord clamping more secure and meeting the safety requirements for push-pull resistant power cords.

[0024] To make the objectives, technical solutions, and advantages of this embodiment clearer, the technical solutions of this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, not all embodiments. Based on the embodiments in this embodiment, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0026] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] For ease of understanding and explanation, the term "lateral" in this application may refer to the radial / circumferential direction of the lighting fixture (or lamp body 3). The term "vertical" in this application may refer to the axial direction of the lighting fixture (or lamp body 3).

[0028] The lighting fixture wire pressing structure and the lighting fixture provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] like Figures 1 to 5 As shown in the figure, this application discloses a lighting fixture wire clamping structure and the lighting fixture thereon. The lighting fixture wire clamping structure is used to clamp and fix the power cord 1 to attach the power cord 1 to the lamp body 3 and / or the insulating shell 4 inside the lamp body 3, thereby preventing the power cord 1 from detaching from the lamp body 3.

[0030] See Figure 1 The lighting fixture wire clamping structure provided by this utility model can be applied to, for example... Figure 1 Among the cylindrical light fixtures shown. Specifically, Figure 1 The luminaire shown may include a power cord 1, a second fastener 2, a lamp body 3, an insulating shell 4, a wire clamping structure, a first fastener 6, a heat-conducting layer 7, a DOB lamp plate 8, a reflector 9, and a face ring 10. Among them, as shown... Figure 2 and Figure 3 As shown, the wire clamping structure may include a wire clamping clip 5 and a wire locking clip 41 installed inside the insulating shell 4 and capable of being combined with each other. Further, in this embodiment, the wire clamping structure may also include a first fastener 6 for connecting and securing the wire clamping clip 5 and the wire locking clip 41. When the wire clamping clip 5 and the wire locking clip 41 are engaged and fixed by the first fastener 6, the power cord 1 is clamped and fixed by both the wire clamping clip 5 and the wire locking clip 41.

[0031] According to a preferred embodiment, Figure 1 The lamp components and wiring structures shown are arranged as follows: Figure 1 After assembly as shown, the resulting lamp structure is as follows: Figure 5 As shown. Figure 5 As shown, a portion of the power cord 1 of the lamp is housed inside the lamp body 3 and is attached and secured to the inside of the lamp body 3 by a wire clamping structure (not shown in the figure). Specifically, the power cord 1 is passed through the power hole (not shown in the figure) of the lamp body 3, and then through the wire clamping groove inside the insulating shell 4. After being inserted to an appropriate length, the power cord 1 is clamped and fixed inside the insulating shell 4 using the wire clamping structure provided in this application.

[0032] Furthermore, a heat-conducting layer 7 and a DOB lamp plate 8 are sequentially laid inside the insulating shell 4. Then, the reflector 9 and the face ring 10 are sequentially installed into the lamp body 3, and the lamp components are connected and fixed by the second fasteners 2 (such as screws or bolts) to complete the assembly.

[0033] According to a preferred embodiment, see Figure 1 The heat-conducting layer 7 has multiple arc-shaped edges in its circumferential structure. When the heat-conducting layer 7 is laid inside the insulating shell 4, the shape of these arc-shaped edges adapts to the multiple arc-shaped protrusions constructed at corresponding positions on the inner wall of the insulating shell 4. Further, see... Figure 1 The thermally conductive layer 7 has a generally rectangular slot formed between two adjacent arcuate edges, which is used to allow the wire clip 41 and the wire clamp 5 to pass through. As a non-limiting example, a preferred example of the thermally conductive layer 7 is thermally conductive tape.

[0034] See Figure 2 The lamp provided in this application embodiment includes a lamp body 3 and a generally cylindrical insulating shell 4 installed inside the lamp body 3. A base plate may be formed inside the insulating shell 4. An annular hole 40 is formed on the base plate. Further, a portion of the base plate, excluding the annular hole 40, is constructed as a generally U-shaped bayonet 400, which guides the power cord 1 to pass through or out of the lamp body 3 in a direction that is generally perpendicular to and intersects the base plate. Preferably, the bayonet 400 communicates with the annular hole 40. Alternatively, the U-shaped bayonet 400 is integrally recessed from a portion of the annular hole 40 along the radially outward side of the lamp body 3.

[0035] According to a preferred embodiment, a wire clip 41 is removably mounted on the bayonet 400 of the inner bottom plate of the insulating shell 4. See also Figure 2 The cable clip 41 may include a cable clipping portion 410 and a fixing portion 420. Two fixing portions 420 are symmetrically arranged on both sides of the cable clipping portion 410, mirror images of each other. Specifically, the cable clipping portion 410 is constructed as a clip block structure. The side of the cable clipping portion 410 facing the annular hole 40 (or power cord 1) is constructed as a generally U-shaped first cable clip groove 411. Alternatively, the cable clipping portion 410 has a first cable clip groove 411, which is disposed facing the annular hole 40 (or power cord 1). When the power cord 1 passes through the first cable clip groove 411 along the axial direction of the lamp body 3, the first cable clip groove 411 is configured to adapt to the outer contour of the power cord 1.

[0036] According to a preferred embodiment, the wire-holding portion 410 has a first protrusion 412 on the side opposite to the first wire-holding groove 411 (or power cord 1). The first protrusion 412 extends vertically (i.e., along the axis of the lamp body 3) from the surface of the wire-holding portion 410. Alternatively, the first protrusion 412 is formed on the side of the wire-holding portion 410 facing the wire clamp 5, and this first protrusion 412 is formed on the side of the first wire-holding groove 411 opposite to the power cord 1. Further, the side of the first protrusion 412 facing the first wire-holding groove 411 (or power cord 1) has an arc-shaped sidewall. This arc-shaped sidewall is configured to conform to the outer contour of the power cord 1.

[0037] According to a preferred embodiment, a first locking block 413 is constructed on the arc-shaped sidewall of the first protrusion 412 facing the power cord 1. The first locking block 413 may be integrally formed by a portion of the first protrusion 412 protruding toward the first wire-locking groove 411 (or the power cord 1). Optionally, when viewed along the axial direction of the lamp body 3 or in a direction substantially vertical and perpendicular to the first wire-locking groove 411, the projection of the first locking block 413 is partially or completely contained within the first wire-locking groove 411.

[0038] Furthermore, the first locking block 413 has a locking portion on the side facing the power cord 1. As an example, the locking portion can be constructed as a bayonet structure with a recessed interface. For example, the locking portion can be constructed as any of the bayonet structures of V-shape, U-shape, and arc shape. Specifically, when the power cord 1 is passed through the first locking groove 411 and contacts the first locking block 413, the locking portion can be used to restrict the lateral (i.e., radial) and / or vertical (i.e. axial) displacement of the power cord 1.

[0039] Specifically, to increase the contact friction between the first latch 413, particularly the latching portion of the first latch 413, and the power cord 1, and to more significantly restrict the vertical and horizontal movement of the power cord 1, in other alternative embodiments of this application, a coating structure with frictional resistance can be constructed on the surface of the latching portion of the first latch 413. For example, the surface of the latching portion can be sanded to increase its surface roughness; or, a rubber layer can be added to the surface of the latching portion. Alternatively, protrusions, corrugations, or other structures can be formed on the surface of the latching portion to increase surface contact friction.

[0040] According to a preferred embodiment, see Figure 2 The wire clip 41 also includes fixing portions 420 arranged on both sides of the wire clip portion 410. As an example, the fixing portion 420 is constructed as a cylindrical structure with a first fixing hole 421. The first fixing hole 421 of the fixing portion 420 is used to guide a first fastener 6 through, so as to connect and fix the wire clip 41 and the wire clamping clip 5 by means of the first fastener 6. Further, a portion of the fixing portion 420 is constructed as a bevel 422. The bevel 422 is formed on the side of the fixing portion 420 opposite to the annular hole 40 and extends obliquely along the side away from the annular hole 40.

[0041] As a non-limiting example, the wire-locking portion 410 and the fixing portion 420 may be integrally formed. Specifically, when the wire-locking buckle 41 is installed or attached to the insulating shell 4, the wire-locking portion 410 of the wire-locking buckle 41 is inserted along the slot 400 of the bottom plate of the insulating shell 4, and the fixing portions 420 on both sides of the wire-locking portion 410 are removably attached to the remaining bottom plate on both sides of the slot 400. Optionally, a connecting hole (not shown in the figure) may be provided on the bottom plate of the insulating shell 4, i.e., on the bottom plate located on both sides of the slot 400, which allows the first fastener 6 to pass through, so as to fix the wire-locking buckle 41 to the bottom plate by means of the first fastener 6. In other embodiments, the wire-locking buckle 41, consisting of the wire-locking portion 410 and the fixing portion 420, may be directly formed on the bottom plate of the insulating shell 4.

[0042] In some alternative embodiments, the wire-locking portion 410 and the fixing portion 420 can be independent of each other. For example, the fixing portion 420 can be formed or mounted on the base plate on both sides of the bayonet 400, and the first fixing hole 421 of the fixing portion 420 is aligned and communicates with the connecting hole on the base plate. Further, the wire-locking portion 410 is inserted along the bayonet 400 of the base plate and abuts against the fixing portion 420 on both sides of the bayonet 400, or is partially embedded in the fixing portion 420, so that the wire-locking portion 410 and the fixing portion 420 are substantially connected as one unit.

[0043] According to a preferred embodiment, the lamp wire clamping structure provided in this application further includes a wire clamping clip 5 that can be combined with the wire clamping clip 41. See also Figure 3 The wire clamp 5 is constructed with a locking block structure that is the same as or similar to that of the wire clip 41. The wire clamp 5 has a locking platform. The locking platform is configured to be stacked on the top surface of the wire clamping portion 410 of the wire clip 41 in the vertical direction (or the axial direction of the lamp body 3). Specifically, the locking platform is provided on one side of the wire clamping portion 410 that has a first protrusion 412 and / or a first locking block 143.

[0044] According to a preferred embodiment, see Figure 3 The wire clamp 5 has a generally U-shaped second wire-holding groove 510 on the side opposite to the annular hole 40. Alternatively, the wire clamp 5 has a second wire-holding groove 510 facing the first wire-holding groove 411 (or power cord 1) of the wire clamp 41. Preferably, the second wire-holding groove 510 is configured to conform to the shape of the first wire-holding groove 411. For example, the first wire-holding groove 411 and the second wire-holding groove 510 are U-shaped slots with substantially the same width.

[0045] According to a preferred embodiment, see Figure 3The side of the wire clamp 5 that engages with the wire clip 41 has a second protrusion 511. Alternatively, the second protrusion 511 is integrally formed on the side of the wire clamp 5 facing away from the second wire slot 510, and this second protrusion 511 extends substantially vertically toward the wire clip 41. Further, the side of the second protrusion 511 facing the second wire slot 510 (or power cord 1) has an arc-shaped sidewall. This arc-shaped sidewall is configured to conform to the outer contour of the power cord 1. In particular, when the wire clamp 5 is engaged on the surface of the wire clamp 41, the projection of the second protrusion 511 along the axial direction of the lamp body 3 is partially or entirely within the first wire slot 411 of the wire clip 41.

[0046] According to a preferred embodiment, a second locking block 512 is constructed on the arcuate sidewall of the second boss 511. The second locking block 512 may be integrally formed by a portion of the second boss 511 protruding toward the second wire-locking groove 510 (or power cord 1). Optionally, when viewed along the axial direction of the lamp body 3 or in a direction substantially vertical and perpendicular to the second wire-locking groove 510, the projection of the second locking block 512 is partially or completely contained within the second wire-locking groove 510.

[0047] Furthermore, the second locking block 512 has a locking portion on the side facing the power cord 1. Similar to or similar to the first locking block 413, this anti-pull portion can be constructed as a bayonet structure with a recessed interface. For example, the bayonet can be constructed as any of the bayonet structures of V-shape, U-shape, and arc shape. Specifically, when the power cord 1 is passed through the second cable slot 510 and contacts the second locking block 512, the locking portion can be used to limit the lateral (i.e., radial) and / or vertical (i.e. axial) displacement of the power cord 1.

[0048] According to a preferred embodiment, see Figure 3 The second wire-locking groove 510 of the wire clamp 5 is symmetrically provided with second fixing holes 513 on both sides, mirror images of each other. The shape of the second fixing holes 513 corresponds to the shape of the first fixing holes 421 on the wire clamp 41. It can be understood that the number of second fixing holes 513 can be one or more pairs. Preferably, the number of second fixing holes 513 corresponds to the number of first fixing holes 421 on the fixing part 420 of the wire clamp 41.

[0049] Furthermore, it is understood that, in addition to using fixing holes (421; 513) and fasteners (such as fixing bolts) to connect and fix the wire clip 41 and the wire clamp 5, those skilled in the art may also choose other possible methods to combine and fix the wire clip 41 and the wire clamp 5. For example, the wire clip 41 and the wire clamp 5 can be glued together; or the wire clip 41 and the wire clamp 5 can be connected and fixed by mutual cooperation of slots and blocks. For example, locking slots can be constructed on both sides of the wire clip 41, and corresponding locking blocks can be constructed on both sides of the wire clamp 5.

[0050] According to a preferred embodiment, see Figure 3 The second wire-locking groove 510 of the wire clamp 5 has sliding ribs 514 arranged symmetrically on both sides, mirror images of each other. A pair of sliding ribs 514 extend substantially vertically toward the wire clamp 41. Alternatively, a pair of sliding ribs 514 are integrally formed on both sides of the bottom of the wire clamp 5 facing the wire clamp 41.

[0051] According to a preferred embodiment, the sliding rib 514 has a mating surface that is at least partially adapted to the shape of the inclined surface 422 of the wire clip 41. For example, the end face of the sliding rib 514 that engages with the wire clip 41 has the same or similar structure as the inclined surface 422. When the wire clip 5 is assembled vertically (or along the axial direction of the lamp body 3) onto the surface of the wire clip portion 410 of the wire clip 41, and the second fixing hole 513 of the wire clip 5 and the first fixing hole 421 of the wire clip 41, the second wire clip groove 510 of the wire clip 5 and the first wire clip groove 411 of the wire clip 41 are kept vertically aligned, the sliding ribs 514 on both sides of the bottom of the wire clip 5 engage with the inclined surfaces 422 on both sides of the wire clip 41 in a shape-adaptive manner.

[0052] The working principle of this utility model is as follows: The power cord 1 is passed through the power hole on the lamp body 3, and then through the first wire-clamping groove 411 of the wire clamping buckle 41 inside the insulating shell 4. After the power cord 1 is inserted to the desired length, the wire clamping buckle 5 is adjusted as follows. Figure 4 The cable is assembled onto the cable clip 41 as shown. The second cable slot 510 of the cable clip 5 receives and surrounds the power cord 1 from the opposite side of the first cable slot 411. Then, the first fastener 6 (such as a cable screw) is sequentially locked into the aligned second fixing hole 513 and first fixing hole 421. During the locking of the first fastener 6, the cable clip 5 is pressed down, causing the sliding rib 514 at the bottom of the cable clip 5 to slide along the inclined surface 422 of the cable clip 41. Simultaneously, the cable clip 5 slides towards the power cord 1 and circumferentially clamps the power cord 1. During the sliding of the cable clip 5, the first locking block 413 of the cable clip 41 and the second locking block 513 of the cable clip 5 are engaged with the power cord 1. The first locking block 413 of the cable clip 41 and the second locking block 513 of the cable clip 5 cooperate to clamp the power cord 1, thereby achieving the effect of preventing the cable harness from being pushed or pulled. After assembly, the first protrusion 412 of the wire clip 41 and the second protrusion 511 of the wire clamp 5 will form an annular hole wall, and the power cord 1 will be stored in the annular receiving hole, thereby better securing the power cord 1.

[0053] This utility model relates to the structural design of a power cord clamping mechanism for lighting fixtures, employing a sliding screw-on bevel method to secure the power cord. Two screw posts are designed on the insulating shell used to fix the power cord. These two screw posts engage with a boss formed by a wire clamp. Sliding bevels are designed on the sides of the two screw posts. An anti-pull / push V-shaped protrusion is constructed at the wire passage hole of the wire clamp. Two oblong screw holes are provided on the wire clamp. A boss for securing the power cord to the insulating shell is constructed in the middle of each oblong screw hole. Sliding ribs are designed on both sides of each oblong screw hole. An anti-pull / push V-shaped protrusion that engages with the insulating shell is provided on the boss between the oblong screw holes.
