Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a wire locking assembly and a lamp. Background Art

[0002] In the current lighting market, wire crimping is often done through direct compression or screw fastening. These methods often present challenges such as heavy loads and complex operation. Due to the heavy loads, excessive pressure can be applied to the wires during tightening, leading to damage to the insulation. Damage to the insulation not only reduces the insulation rating of the wires but can also lead to safety hazards such as short circuits and electrical leakage, posing a serious threat to the safety and service life of the lighting fixtures.

[0003] Furthermore, traditional crimping methods require manual adjustment of the insulation during tightening to prevent leakage of the inner core. This step not only complicates the operation but also easily leads to inaccurate adjustments due to human error, which in turn affects the electrical performance and safety of the lamp.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0037] See also Figures 1 to 11 As shown, an embodiment of the present invention provides a lamp 200, comprising a cable 110, a housing 120, a face ring 1202 disposed on the housing 120, and a light source module (not shown) disposed within the housing 120. The cable 110 includes an insulating portion 1101 and an inner core 1102 at least partially exposed from the insulating portion 1101. The inner core 1102 of the cable 110 is connected to the electronic components within the housing 120. The side of the housing 120 proximal to the face ring 1202 is a light emitting end 1203. Light emitted by the light source module is emitted from the face ring 1202 toward the light emitting end 1203.

[0038] See also Figures 2 to 4 As shown, the top of the housing 120 is further provided with a mounting groove 1201, and the bottom surface of the mounting groove 1201 is provided with a mounting hole 1204. After the cable 110 passes through the mounting hole 1204, it is connected to the electronic components within the housing 120. The mounting hole 1204 extends downward from the bottom surface to form an extension portion 1205. The extension portion 1205 has a first engaging surface, which is an inclined surface. The first engaging surface includes a first end proximal to the bottom surface and a second end facing away from the bottom surface. From the first end to the second end, the distance between the first guide surface and the outer side wall of the extension portion 1205 gradually increases.

[0039] See also Figures 2 to 5As shown, to secure the cable 110 to the housing 120, the lamp 200 is further provided with a wire locking assembly 100. The wire locking assembly 100 includes a pressing member 2 and a wire locking member 1. After the wire locking member 1 pre-tightens the cable 110, the pressing member 2 presses against the wire locking member 1 until the wire locking member 1 partially enters the mounting hole 1204, causing the wire locking member 1 to engage with the mounting hole 1204. The cable 110 then passes through the mounting hole 1204, completing the fixed connection between the cable 110 and the housing 120. Preferably, the installation process of the cable 110 can be completed by mechanically manipulating the pressing member 2 to press against the wire locking member 1, which is suitable for mass production and automated production, greatly improving production efficiency.

[0040] See also Figure 7 As shown, in this embodiment, the pressing member 2 is a jig. In other embodiments, the pressing member 2 may also be other pressing tools, which is not limited here. The pressing member 2 includes a pressing end 21, and the pressing end 21 includes a mating surface 22 and a cavity 23 extending from the mating surface 22 in a direction away from the pressing end 21. The mating surface 22 is used to abut against the wire locking member 1. The cavity 23 is used to place the cable 110, and the top of the cavity 23 is provided with an inclined bending surface 24, which helps to straighten the direction of the cable 110. During the pressing process, the cable 110 can be smoothly placed in the cavity 23, avoiding the difficulty of pressing or damage to the cable 110 due to the disorder of the cables 110, which in turn leads to a reduction in the insulation level.

[0041] See also Figure 8 As shown, the thread lock 1 includes a body 11, an elastic wall 12 and a thread groove 13. The body 11 is provided with a thread opening 111. The elastic wall 12 is connected to the body 11 and extends in a direction away from the body 11. In addition, the elastic wall 12 is arranged around the thread opening 111. The first direction is defined as the height extension direction of the housing 120, as shown in FIG. Figure 5 The second direction is defined as the length extension direction of the housing 120, as shown in FIG. Figure 5 The x-axis direction is shown. The width direction of the housing 120 is defined as Figure 5 The first and second directions are perpendicular to the width direction. A cable groove 13 extending along the first direction is formed in the middle of the elastic wall 12 and communicates with the cable opening 111. The cable groove 13 provides accommodation space for the cable 110. As the cable 110 passes through the cable opening 111 and the cable groove 13 in sequence, the elastic wall 12 exhibits a certain degree of elastic adaptability, and through its elastic deformation, it tightly wraps the cable 110, achieving a secure fixation.

[0042] See also Figures 8 to 11As shown, the body 11 includes a first portion 112 and a second portion 113. The first portion 112 includes a head portion 1121 and a tail portion 1122 disposed opposite each other. The second portion 113 is connected to the tail portion 1122 and extends from the tail portion 1122 away from the first portion 112. The first portion 112 includes an abutment surface 1123 disposed away from the second portion 113. The abutment surface 1123 and the mating surface 22 are disposed in a corresponding manner. Furthermore, when the pressing member 2 presses against the thread locking member 1, the abutment surface 1123 abuts the mating surface 22. The second portion 113 includes a snap-fit ​​surface 1131 disposed away from the first portion 112.

[0043] See also Figures 8 to 11 As shown, the elastic wall 12 includes an inner side surface 121 facing the wire groove 13, and an abutment portion 1211 is provided on the inner side surface 121. In some embodiments, the inner side surface 121 is provided with an abutment portion 1211. In other embodiments, the inner side surface 121 is provided with multiple abutment portions 1211, which can apply more abutment and friction to the insulating portion 1101 to improve the clamping degree of the insulating portion 1101. When the cable 110 passes through the wire groove 13, the abutment portion 1211 abuts against the insulating portion 1101, and the two are in close contact. The elastic wall 12 stretches outward to tightly wrap the insulating portion 1101, thereby effectively fixing the insulating portion 1101 in the wire groove 13. At this time, the pre-clamping of the cable 110 by the wire locking member 1 is completed.

[0044] The abutment portion 1211 includes an abutment end 1212 away from the inner side surface 121, and the inner side surface 121 includes an opposite surface 122 opposite to the abutment end 1212. In the second direction, there is a first distance between the abutment end 1212 and the opposite surface 122. It ensures that only the insulating portion 1101 can enter the abutment portion 1211 and be fixed by snapping. This design not only achieves the precise positioning of the cable 110, but also avoids the exposure of the inner core portion 1102, thereby effectively preventing safety hazards such as leakage. The first distance is less than or equal to the outer diameter of the insulating portion 1101. In addition, the first distance is greater than the diameter of the inner core portion 1102. The inner core portion 1102 can pass through the wire groove 13 and enter the interior of the shell 120, ensuring that the inner core portion 1102 is below the abutment portion 1211 of the wire groove 13, avoiding the inner core portion 1102 from leaking out and causing the risk of leakage, which is conducive to improving the insulation level.

[0045] When the insulating portion 1101 enters the wire groove 13, the abutment portion 1211 will abut and fix therewith, and partially open the elastic wall 12. This ensures that the clamping and fixing can only be achieved when the insulating portion 1101 enters the abutment portion 1211. This achieves the precise positioning of the cable 110, avoids the exposure of the inner core portion 1102, and effectively prevents safety hazards such as leakage. With this arrangement, only when the insulating portion 1101 enters the abutment portion 1211 will the insulating portion 1101 and the abutment portion 1211 be clamped and fixed, achieving the positioning and installation of the cable 110. Preventing the inner core portion 1102 from being exposed is conducive to improving the insulation level.

[0046] See also Figures 8 to 11 As shown, the inner side surface 121 is provided with at least two oppositely arranged abutting portions 1211, and the abutting portions 1211 abut against the cable 110, so that the cable 110 is doubly fixed and supported in the wire groove 13. Each abutting portion 1211 includes an abutting end 1212 away from the elastic wall 12. In the second direction, there is a first distance between the two abutting ends 1212. The first distance is less than or equal to the diameter of the insulating portion 1101, and the first distance is greater than the diameter of the inner core portion 1102. It is ensured that the clamping fixation can be achieved only when the insulating portion 1101 enters the abutting portion 1211, thereby achieving the precise positioning and installation of the cable 110.

[0047] In the first direction, the two abutting ends 1212 are staggered and can abut against different parts of the insulating portion 1101 , further clamping the insulating portion 1101 and firmly fixing the insulating portion 1101 in the wire locking member 1 .

[0048] The abutting portion 1211 includes a connecting portion 1213 connected to the inner side surface 121 and an abutting end 1212 disposed away from the inner side surface 121. The connecting portion 1213 includes an end proximal to the body 11, with an inclined guide surface 1214 disposed between the end and the abutting end 1212. The inclined guide surface 1214 includes an end proximal to the cable inlet and an end distal to the cable inlet. The distance between the inclined guide surface 1214 and the inner side surface 121 gradually increases from the end proximal to the cable inlet to the end distal to the cable inlet. The inclined guide surface 1214 can guide the cable 110 through the cable trough 13, reducing friction caused by inaccurate or obstructed cable 110 direction, and improving the smoothness of the cable 110 passing through the cable trough 13.

[0049] See also Figures 8 to 11 As shown, in some embodiments, the elastic wall 12 further includes a first elastic wall 123 and a second elastic wall 124. A strip groove 125 extending along a first direction is defined between the first elastic wall 123 and the second elastic wall 124. When the cable 110 is deformed by an external force, the strip groove 125 provides space for deformation, relieves stress, and prevents the cable 110 from being squeezed and damaged.

[0050] The first elastic wall 123 is connected to the first portion 112 and extends downward from the first portion 112. The second elastic wall 124 is connected to the second portion 113. A free wall 1231 is provided on the first elastic wall 123. The free wall 1231 is positioned near the head portion 1121. A certain height difference exists between the free wall 1231 and the head portion 1121, providing a greater elastic deformation space for the free wall 1231. At least one abutting portion 1211 is provided on the inner side surface 121 of the free wall 1231. When subjected to pressure from the cable 110, the free wall 1231 can move and deform more freely, allowing the abutting portion 1211 to abut more tightly against the insulating portion 1101, thereby more effectively abutting and securing the cable 110.

[0051] The outer surfaces of both the first and second elastic walls 123 and 124 are provided with protrusions 126, forming an annular groove 127 between the protrusions 126 and the locking surface 1131. A locking portion 1232 is provided at the top of the free wall 1231. The lowest surface of the locking portion 1232 is aligned with the locking surface. The lowest surface of the locking portion 1232 and the locking surface abut against the bottom surface of the mounting groove 1201, preventing the thread locking member 1 from moving downward excessively and acting as a position limiter. A locking groove is formed between the bottom surface of the locking portion 1232 and the protrusions 126. The locking groove overlaps with the annular groove 127.

[0052] The outer side surface of the protrusion 126 is an inclined surface, and the protrusion 126 has a bottom surface away from the locking portion 1232. The protrusion 126 is inclined outward from the bottom surface of the locking portion 1232, which facilitates the protrusion 126 to gradually enter the installation groove 1201.

[0053] The top of the protrusion 126 has a second engaging surface connected to the outer side surface, and the second engaging surface is arranged corresponding to the first engaging surface. The first engaging surface can be tightly fitted with the second engaging surface, which plays an anti-pull effect on the wire locking assembly 100.

[0054] The installation process for cable 110 is as follows: Cable 110 is passed through cable trough 13. As cable 110 moves, abutment portion 1211 abuts against insulation portion 1101. The two come into close contact, causing elastic wall 12 to expand outward, tightly enveloping insulation portion 1101. This effectively secures insulation portion 1101 within cable trough 13. At this point, cable 110 no longer moves, completing the pre-tightening of cable 110 by wire lock 1.

[0055] The wire locking member 1 is installed in the mounting groove 1201, and the portion of the wire locking member 1 with the cable 110 secured thereto enters the mounting hole 1204. The wire locking member 1 is pressed downward by the pressing member 2, that is, the mating surface 22 of the pressing member 2 abuts the abutting surface 1123. The pressing member 2 presses the wire locking member 1 downward, causing it to continue moving downward until the snap surface 1131 abuts the bottom surface of the mounting groove 1201, and the inner core 1102 extends into the housing 120. During this process, the elastic wall 12 passes through the mounting hole 1204 and enters the housing 120. The elastic wall 12, which is held open by the insulating portion 1101, is squeezed inward by the housing 120, and the abutting portion 1211 presses the insulating portion 1101 inward, further securing the cable 110. At this point, the first and second snapping surfaces are tightly fitted, and the extension portion 1205 is snapped and secured to the annular snap groove 127, completing the installation of the cable 110.

[0056] In summary, the wire locking assembly 100 of the present invention provides an abutment portion 1211 on the wire trough 13, which abuts the insulating portion 1101 to secure the insulating portion of the cable 110 within the wire trough 13, thereby achieving positioning and fixation of the cable 110. Compared to the prior art, the wire locking assembly 100 of the present invention employs an ingenious structural design. As the cable 110 passes through the wire opening 111 and is pushed into the wire trough 13, the natural elastic force of the elastic wall 12 causes the abutment portion 1211 to tightly fit the insulating portion 1101 of the cable, thereby completing the pre-tightening installation of the cable 110. No additional fasteners or tools are required, greatly simplifying the installation process and making it easy to operate.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
