[0033] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0034] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0035] The following will, in conjunction with the accompanying drawings, describe in detail the wire pressing member and the electrical device provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0036] Referring to Figures 1 - 12 , a wire pressing member provided by an embodiment of the present application is used to be disposed on the housing 400 of an electrical device. The wire pressing member 200 may include a main body 210 and a wire pressing portion 220. The wire pressing portion 220 may be used to press the wire 100.

[0037] Among them, the main body 210 may be provided with a wire passing hole 250 and a notch 260. The wire passing hole 250 may penetrate the main body 210 and be used for the wire 100 to pass through. The notch 260 may be located on one side of the wire passing hole 250, and the notch 260 may communicate with the wire passing hole 250. The wire pressing portion 220 is movably disposed in the notch 260 so as to be able to move in a direction close to the wire passing hole 250 to press the wire 100, so that the wire 100 is pressed on the housing 400 of the electrical device.

[0038] In this way, when the wire 100 is subjected to a strong pull, part of the external force received can be conducted to the housing 400 of the electrical device. The welding points connected to the wire 100 on the circuit board are not easily detached, the electrical conductivity between the wire 100 and the circuit board can be ensured, the wire 100 is not easily pulled out and can supply power to the circuit board normally, so that the normal use of the electrical device can be ensured.

[0039] Here, the electrical device may be a device such as a lamp, a computer, a television, etc. Exemplarily, the electrical device in this embodiment may be a lamp, and the circuit board described above may be the lamp board of the light source assembly 500.

[0040] It should be noted that the size of the wire pressing member 200 may be adapted to the size of the electrical device, so that the wire pressing member 200 can be applicable to electrical devices of different sizes, and the wire pressing member 200 will not be unable to press the wire 100 due to the small size of the electrical device.

[0041] In an alternative embodiment of the present application, the wire pressing portion 220 may be located in the notch 260, and the wire pressing portion 220 may be connected to the groove wall of the notch 260 through at least two elastic arms 230. In this way, compared with the way that the wire pressing portion 220 described below is not connected to the groove wall of the notch 260, it is more convenient for the wire pressing portion 220 to move in the notch 260 and for the wire pressing portion 220 to press the wire 100, and the structure is simple. In other embodiments, the wire pressing portion 220 may not be connected to the groove wall of the notch 260. Specifically, the wire pressing portion 220 may be movably connected to the housing 400.

[0042] Optionally, each elastic arm 230 can be circumferentially distributed along the notch 260. In this way, the force balance of the wire pressing part 220 can be ensured, and it is not easy to deviate during the movement of the wire pressing part 220.

[0043] In an alternative embodiment, a groove 221 can be provided on the wire pressing part 220, and the pressing member 300 of the electrical device can be embedded in the groove 221 to push the wire pressing part 220 to move towards the direction close to the wire passing hole 250, so as to press the wire pressing part 220 against the wire 100.

[0044] Moreover, along the direction from the wire passing hole 250 to the notch 260, the cross-sectional area of the groove 221 gradually increases. In this way, it is convenient for the pressing member 300 to push the wire pressing part 220, and the groove 221 can play a role in positioning the pressing member 300. During the pressing process, it can be ensured that the wire pressing part 220 will not shift or deviate.

[0045] Certainly, the groove 221 may not be provided on the wire pressing part 220, and the pressing member 300 can directly press against the surface of the wire pressing part 220 facing away from the wire passing hole 250.

[0046] In an alternative embodiment, the wire pressing member 200 may further include a positioning part 240. The positioning part 240 can protrude from the outer wall of the main body 210, and the positioning part 240 can be in limit fit with the light source assembly 500 of the electrical device in the direction from the wire pressing part 220 to the positioning part 240. In this way, when the wire pressing member 200 is installed on the electrical device, the wire pressing member 200 can be positioned, so as to facilitate the alignment of the wire pressing part 220 with the connection hole 412 described below. The installation is simple and conducive to saving installation time.

[0047] In other embodiments, the wire pressing member 200 may not include the positioning part 240.

[0048] In this embodiment, the main body 210 can be in a cylindrical structure, the wire passing hole 250 is coaxially arranged with the main body 210, and the wire pressing member 200 can be made of a flexible material, such as plastic.

[0049] Based on the wire pressing member provided by the embodiments of the present application, the embodiments of the present application further provide an electrical device. The electrical device may include a housing 400, a wire 100 and a wire pressing member. The wire pressing member 200 can be arranged on the housing 400. The wire 100 can pass through the wire passing hole of the wire pressing member 200, and a pressing member 300 can be arranged on the housing 400. The pressing member 300 can push the wire pressing part 220 of the wire pressing member 200 to press the wire 100.

[0050] Here, the housing 400 can be made of a heat-conducting material. Specifically, the housing 400 can be made of a metal material. In this way, the housing 400 can dissipate the heat of the electrical device. The wire 100 can be electrically connected to the circuit board inside the housing 400. Specifically, when the electrical device is a lamp, the wire 100 can be electrically connected to the light source assembly 500 inside the housing 400.

[0051] The beneficial effects achieved by the electrical device provided in the embodiments of the present application are consistent with the beneficial effects achieved by the wire pressing member 200 provided in the embodiments of the present application, so they will not be elaborated here.

[0052] In an alternative embodiment of the present application, through holes 420 and connection holes 412 can be provided on the housing 400. The connection hole 412 can be located on one side of the through hole 420 and communicate with the through hole 420. The wire pressing member 200 is located in the through hole 420, and the wire pressing portion 220 faces the connection hole 412. The pressing member 300 is detachably connected to the connection hole 412 and can pass through the connection hole 412 to press against the wire pressing portion 220, so that the wire pressing portion 220 presses the wire 100. In this way, by providing the through holes 420 on the housing 400 and placing the wire pressing member 200 in the through holes 420, the contact between the wire 100 and the housing 400 can be reduced, and the risk of short circuit or electric leakage can be lowered.

[0053] In this embodiment, the connection hole 412 can be a threaded hole, and the pressing member 300 can be a screw threadedly connected to the threaded hole. Of course, the pressing member 300 can be a protrusion provided on the housing 400, and the protrusion can press against the wire pressing portion 220 to make the wire pressing portion 220 press the wire 100. Here, the protrusion can be embedded in the groove 221 of the wire pressing portion 220.

[0054] In other embodiments, the housing 400 may not be provided with through holes 420, and the wire pressing member 200 is connected to the end face or outer wall of the housing 400.

[0055] In an alternative embodiment, a wire fixing portion 410 can be provided inside the housing 400. The wire fixing portion 410 can be connected to the first part of the housing 400 and enclose a through hole 420. A convex portion 411 is provided on the side of the wire fixing portion 410 facing away from the first part. The convex portion 411 protrudes away from the first part, and a first connection hole can be provided on the convex portion 411. A second connection hole can be provided on the wire fixing portion 410. The first connection hole and the second connection hole are coaxially connected. The connection hole 412 can include the first connection hole and the second connection hole. In this way, compared with the connection hole 412 being provided on the first part of the housing 400, the axial length of the connection hole 412 can be longer, that is, the depth of the connection hole 412 is deeper, and more threads can be provided on the connection hole 412 to increase the torque between the pressing member 300 and the connection hole 412.

[0056] Of course, the connection hole 412 may be provided on the first portion of the housing 400 .

[0057] Optionally, a through hole 430 may be provided on the second portion of the housing 400, and the through hole 430 may be coaxially connected with the second connecting hole, and the abutting member 300 may extend into the second connecting hole through the through hole 430. In this way, the abutting member 300 is convenient to extend into the connecting hole 412, which is convenient for the operator to operate.

[0058] Of course, the through hole 430 may not be provided on the second portion of the housing 400 , and the abutting member 300 may enter the housing 400 from the side of the housing 400 away from the light source assembly 500 and extend into the second connecting hole.

[0059] In an optional embodiment, the housing 400 may be provided with an anti-rotation groove 460, which may be provided on the hole wall of the through hole 420, and the wire pressing portion 220 may be embedded in the anti-rotation groove 460 and cooperate with the anti-rotation groove 460 in the circumferential upper limit of the through hole 420. In this way, when the wire pressing portion 220 is pushed, the anti-rotation groove 460 may prevent the wire pressing member 200 from rotating and causing the wire pressing portion 220 to deviate from the abutting member 300.

[0060] In other embodiments, the anti-rotation groove 460 may not be provided on the housing 400 .

[0061] Optionally, the pressing member 300 may be provided with a pressing portion 310, which may be embedded in the groove 221 on the wire pressing portion 220, and the cross-sectional area of ​​the pressing portion 310 gradually increases along the direction from the connecting hole 412 to the through hole 420. In this way, the pressing member 300 is convenient for pushing the wire pressing portion 220, and the groove 221 can play a role in positioning the pressing portion 310, and during the pressing process, it can be ensured that the wire pressing portion 220 will not shift or deviate.

[0062] In an alternative embodiment, the electrical device can be a lighting fixture, which can include a light source assembly 500. The light source assembly 500 can be disposed within a housing 400 and electrically connected to a wire 100. Here, one end of the wire 100 can be soldered to the lamp board of the light source assembly 500. A through groove 520 can be provided on the light source assembly 500, and the through groove 520 can communicate with a through hole 420. Specifically, the through groove 520 can be disposed below the through hole 420. A wire pressing member 200 can pass through the through groove 520, and the positioning portion 240 of the wire pressing member 200 is in limit fit with the light source assembly 500 in the direction from the through hole 420 to the through groove 520. Among them, since the wire pressing member 200 passes through the through groove 520, this can further ensure that the wire 100 does not contact the side wall of the housing 400 and ensure that the wire 100 does not contact the light source assembly 500 except at the welding point. This can not only reduce the risk of short circuit or electric leakage, but also avoid abrasion of the wire 100 with the housing 400 or the light source assembly 500, which is beneficial to improving the service life of the wire 100.

[0063] Of course, the wire pressing member 200 may not pass through the through groove 520.

[0064] In an alternative embodiment of the present application, the electrical device can further include a lens 600 and a fixing cover 700. The lens 600 can be disposed on the light-emitting side of the light source assembly 500. The lens 600 is used to collect the light emitted by the light source assembly 500 and reflect the light, so as to improve the utilization rate of the light. The fixing cover 700 is sleeved outside the lens 600, and the fixing cover 700 is connected to the housing 400. One end of the lens 600 close to the light source assembly 500 contacts the lamp board of the light source assembly 500, and the end of the lens 600 far from the light source assembly 500 contacts the fixing cover 700.

[0065] In this embodiment, the lens 600 can be a TIR lens (Total Internal Reflection lens). The TIR lens is a lens designed based on the principle of total internal reflection. Total internal reflection is an optical phenomenon. When light travels from a medium with a high refractive index to a medium with a low refractive index, if the incident angle is greater than a certain critical angle, the light will no longer refract but be completely reflected back into the medium with a high refractive index. The TIR lens utilizes this principle. By carefully designing and processing the light, it uses transmissive light collection on the front, and at the same time collects and reflects all the side light through a conical surface. The TIR lens has the advantages of high efficiency, low loss, small light collection area and good uniformity, and can achieve the collection and shaping of the light source.

[0066] Specifically, the lens 600 is provided with a light incident cavity 610 and a light exiting cavity 620. The light exiting cavity 620 is arranged away from the light source assembly 500, and a partition 630 is arranged between the light incident cavity 610 and the light exiting cavity 620. The partition 630 protrudes towards the light exiting cavity 620. The side of the partition 630 facing away from the light source assembly 500 is spherical. The side of the partition 630 facing away from the light source assembly 500 and the cavity wall of the light exiting cavity 620 together form the light exiting surface of the lens 600. The light incident cavity 610 is arranged close to the light source assembly 500, and the light emitting element 510 of the light source assembly 500 is located in the light incident cavity 610. In this way, more light emitted by the light source assembly 500 can be incident into the lens 600 from the light incident cavity 610.

[0067] Here, along the direction from the light source assembly 500 to the lens 600, the cross-sectional area of the light incident cavity 610 gradually decreases. In this way, more light emitted by the light source assembly 500 can be irradiated onto the partition 630.

[0068] Along the direction from the light source assembly 500 to the lens 600, the cross-sectional area of the lens 600 gradually increases. In this way, the light exit angle of the electrical equipment can be increased.

[0069] Optionally, the fixing cover 700 is provided with an annular fixing portion 710. The annular fixing portion 710 is arranged inside the fixing cover 700 and is arranged away from the light source assembly 500. One end of the lens 600 facing away from the light source assembly 500 abuts against the annular fixing portion 710. Here, an elastic protrusion 640 is arranged at one end of the lens 600 facing away from the light source assembly 500. The elastic protrusion 640 can abut against the annular fixing portion 710. In this way, the elastic protrusion 640 can absorb the tolerance between the lens 600 and the annular fixing portion 710, which is beneficial to improving the service life of the lens 600 and the fixing cover 700.

[0070] In this embodiment, the fixing cover 700 can be snap-connected to the housing 400. Specifically, one of the fixing cover 700 and the housing 400 is provided with a snap, and the other is provided with a slot, and the snap can be inserted into the slot.

[0071] Here, a fixing plate 440 and an installation space 450 can be arranged inside the housing 400. The installation space 450 can be located on the side of the fixing plate 440 close to the front frame assembly 800. The light source assembly 500 can be located in the installation space 450 and connected to the fixing plate 440. The through hole 420 can penetrate through the fixing plate 440, and a part of the fixing cover 700 can be located in the installation space 450.

[0072] In an alternative embodiment, the electrical device may further include a front frame assembly 800. The front frame assembly 800 may be disposed on the light-emitting side of the light source assembly 500. The front frame assembly 800 may be connected to the housing 400 and may be used to connect to the basic mounting mechanism 1100 so that the electrical device is mounted on the basic mounting mechanism 1100. Here, the electrical device may be a lamp. Specifically, the electrical device may be an LED spot lamp.

[0073] The front frame assembly 800 is rotatably connected to the housing 400, and a rotation space 900 may be left between the front frame assembly 800 and the housing 400. In this way, the front frame assembly 800 and the housing 400 can be rotated relative to each other to adjust the light-emitting angle of the electrical device.

[0074] In addition, the front frame assembly 800 may include a reflector cup 830, a fixing cover, and a connecting ring 840. The reflector cup 830 is used to reflect and diffuse the light emitted by the light source assembly 500 to enhance the lighting range and intensity of the electrical device so that the electrical device can illuminate a farther distance. The fixing cover is sleeved outside the reflector cup 830. The first part of the connecting ring 840 can be attached to the housing 400, and the second part of the connecting ring 840 extends into the fixing cover and is snap-connected to the fixing cover. Moreover, the connecting ring 840 and the fixing cover 700 are rotatably connected. Specifically, a rotation groove 721 is provided on one of the connecting ring 840 and the fixing cover 700, and a rotating shaft 841 is provided on the other. The rotating shaft 841 is embedded in the rotation groove 721 and can rotate within the rotation groove 721. Of course, the rotation groove 721 can be a ball groove, and the rotating shaft 841 can be a ball shaft.

[0075] Here, a connecting portion 720 is provided on the fixing cover 700. The connecting portion 720 is disposed at one end of the fixing cover 700 facing away from the light source assembly 500, and the rotation groove 721 may be provided on the connecting portion 720.

[0076] The rotation space 900 is provided between the connecting ring 840 and the housing 400.

[0077] A part of the connecting ring 840 may be sleeved outside the reflector cup 830. A convex block 831 may be provided on the outer wall of the reflector cup 830, and the convex block 831 may be in contact with the fixing cover to realize the connection between the reflector cup 830 and the fixing cover.

[0078] The electrical device may further include at least two cantilever hooks 1000, part of which is connected to the fixed cover, and the other part of which is connected to the base mounting mechanism 1100.
