[0003] Existing cables are usually fixed by screw crimping or gluing, which requires ensuring that the cables and screws are accurately aligned or adding a gluing step during installation, which undoubtedly makes the installation process more complicated and cannot guarantee the stability of cable fixation.

[0004] In view of this, it is necessary to improve the existing wire pressing method to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a wire crimping assembly, which can simplify the installation process of the wire crimping piece and ensure the stability of the wire crimping assembly.

[0007] The bearing member has a receiving cavity and a wire passing cavity that are communicated with each other;

[0008] A wire pressing member is used to fix the cable on the bearing member. The wire pressing member includes a base assembled in the receiving cavity and a limiting portion provided on the base and accommodated in the wire passing cavity. The limiting portion includes an elastic arm connected to the base, and the limiting portion is provided with a reserved space passing through the base and the limiting portion;

[0009] Among them, the reserved space is configured for the cable to pass through, and allows the cable to elastically abut against the elastic arm, so that the elastic arm is elastically deformed away from the cable; when the limiting part is accommodated in the wire passing cavity, the elastic arm abuts against the inner wall surface of the wire passing cavity to squeeze the cable.

[0010] As a further improvement of the present invention, the elastic arm includes a first elastic arm and a second elastic arm arranged opposite to each other, and a reserved space is formed between the first elastic arm and the second elastic arm. One end of the first elastic arm is connected to the base, and the other end is elastically pressed against one side of the cable. One end of the second elastic arm is connected to the base, and the other end is elastically pressed against the other side of the cable.

[0011] As a further improvement of the present invention, in the extension direction of the limiting portion, the extension lengths of the first elastic arm and the second elastic arm are different.

[0012] As a further improvement of the present invention, a guide surface is provided on the inner wall surface of the wire passing cavity. In the extension direction of the cable, the guide surface divides the wire passing cavity into a first cavity and a second cavity with different cross-sectional areas, and the first cavity is close to the receiving cavity. The cross-sectional area of ​​the first cavity is larger than the cross-sectional area of ​​the second cavity. When the limiting portion is located in the second cavity, the elastic arm elastically deforms toward the reserved space and presses the cable.

[0013] As a further improvement of the present invention, the elastic arm includes a free end away from the base body, and the free end is provided with a pressing surface with a shape adapted to the cable.

[0014] As a further improvement of the present invention, a side of the free end facing away from the pressing surface is provided with an engaging surface capable of cooperating with the guide surface and sliding along the guide surface.

[0016] As a further improvement of the present invention, a positioning hole communicating with the receiving cavity is further provided in the carrier, and a positioning groove corresponding to the positioning hole is provided on the base.

[0017] As a further improvement of the present invention, the wire crimping assembly also includes a positioning member, which passes through the positioning hole and the positioning groove at the same time to fix the wire crimping member on the supporting member. At the same time, the end of the limiting part enters the second cavity from the first cavity.

[0018] Another object of the present invention is to provide a lamp that can simplify the installation process of the wire pressing piece and ensure the stability of the wire pressing assembly.

[0019] To achieve the above-mentioned purpose, the utility model provides a lamp, including the aforementioned wire pressing assembly and cable, the supporting part is a heat sink, the wire pressing part is a light source bracket, and the base of the light source bracket is provided with an assembly space for installing a light source board. The cable is mechanically and electrically connected to the light source board after passing through the wire cavity and the reserved space.

[0020] The beneficial effects of the present invention are as follows: the wire crimping assembly of the present invention is configured with a receiving cavity and a wire passing cavity that are interconnected within a carrier, so that the base of the wire crimping member is assembled within the receiving cavity and the limiting portion of the wire crimping member is accommodated within the wire passing cavity; in addition, an elastic arm connected to the base is provided on the limiting portion of the wire crimping member, so that when the cable passes through the reserved space of the limiting portion, it elastically abuts against the elastic arm and can be elastically deformed away from the cable; and when the limiting portion is accommodated in the wire passing cavity, the elastic arm abuts against the inner wall surface of the wire passing cavity to squeeze the cable. In this way, the wire crimping and fixing of the cable is achieved, and the installation method is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] 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.

[0034] See also Figure 1 and Figure 2As shown, the present invention discloses a wire crimping assembly 100 suitable for use in a lighting fixture to compress and secure a cable 3. The wire crimping assembly 100 includes a carrier 1 and a wire crimping member 2. The carrier 1 provides a mounting base for the wire crimping member 2 and the cable 3. When the wire crimping member 2 is mounted on the carrier 1, it simultaneously secures the cable 3 to the carrier 1.

[0035] Please combine Figure 3 As shown, in this embodiment, a receiving cavity 11 and a base 10 are provided within the carrier 1. A wire hole 13 is provided on the side of the base 10 facing away from the receiving cavity 11. The receiving cavity 11 and the wire hole 13 are interconnected, and a wire cavity 12 is formed between the receiving cavity 11 and the wire hole 13, such that the wire cavity 12 passes through the base 10. The receiving cavity 11 and the wire cavity 12 are interconnected, and the cable 3 passes through the wire hole 13 and the wire cavity 12 and then enters the receiving cavity 11 of the carrier 1.

[0036] The receiving chamber 11 and the wire passing chamber 12 are used to receive the wire pressing member 2. One end of the wire pressing member 2 is received in the wire passing chamber 12 and fixes the cable 3.

[0037] Please combine Figure 4 As shown, a guide surface 120 is provided on the inner wall surface of the wire passing cavity 12 to separate the wire passing cavity 12 into a first cavity 121 and a second cavity 122 with different cross-sectional areas in the extension direction of the cable 3. In the axial direction of the wire passing cavity 12, the first cavity 121 is close to the receiving cavity 11. The second cavity 122 is close to the wire passing hole 13. The cross-sectional area of ​​the first cavity 121 is larger than the cross-sectional area of ​​the second cavity 122. When one end of the wire pressing member 2 accommodated in the wire passing cavity 12 enters the second cavity 122 from the first cavity 121, the wire pressing member 2 presses and fixes the cable 3. Preferably, the guide surface 120 is an inclined surface inclined toward the axial direction of the wire passing cavity 12.

[0038] Of course, the guide surface 120 may not be provided. It is only necessary to ensure that the wire passing cavity 12 can apply pressure to the wire pressing member 2, and then ensure that the wire pressing member 2 can press and fix the cable 3 in the wire passing cavity 12.

[0039] A positioning hole 14 communicating with the receiving cavity 11 is further provided in the carrier 1. The positioning hole 14 is also provided on the base 10. The opening direction of the positioning hole 14 is the same as the opening direction of the wire passage cavity 12. The carrier 1 is fixedly connected to the wire pressing member 2 via the positioning hole 14. Of course, in other embodiments, other fixing methods, such as snap fasteners, etc., may also be adopted, as long as it is ensured that the wire pressing member 2 can be fixed to the carrier 1, and no limitation is imposed on this.

[0040] Please combine Figure 5As shown, in this embodiment, the wire pressing member 2 includes a base 21 and a limiting portion 22 provided on the base 21. The base 21 is assembled in the receiving cavity 11 and is fixedly connected to the base 10 of the carrier 1. The limiting portion 22 passes through and is accommodated in the wire passing cavity 12. An elastic arm 221 is provided on the limiting portion 22. One end of the elastic arm 221 is connected to the base 21. The other end of the elastic arm 221 is a free end 2213. The extension direction of the elastic arm 221 is the same as the extension direction of the limiting portion 22.

[0041] Optionally, in this embodiment, the limiting portion 22 extends along the extension direction of the cable 3 , that is, extends from the base 21 along the axial direction of the carrier 1 . However, this should not be limiting.

[0042] The limiting portion 22 further defines a reserved space 220 extending through the base 21 and the limiting portion 22. An elastic arm 221 is positioned on the periphery of the reserved space 220 to allow the cable 3 to pass through and be accommodated within the reserved space 220. When the cable 3 passes through the reserved space 220, the outer side of the cable 3 abuts against the free end 2213 of the elastic arm 221, causing the elastic arm 221 to elastically deform away from the cable 3.

[0043] That is, when the cable 3 is installed on the limiting portion 22 of the wire pressing member 2, the cable 3 will fully contact the inner wall surface of the limiting portion 22 and expand the elastic arm 221 on the limiting portion 22 to expand the cross-sectional area of ​​the limiting portion 22.

[0044] Preferably, Figure 6 As shown, a pressing surface 22131 is provided on the free end 2213 of the elastic arm 221. This pressing surface 22131 is disposed toward the reserved space 220 and is preferably configured as a concave surface adapted to the outer contour of the cable 3. Of course, in other embodiments, a protrusion facing the reserved space 220 may be provided on the free end 2213 to compress and secure the cable 3, without limitation as long as the cable 3 can be compressed.

[0045] Optionally, the pressing surface 22131 of the elastic arm 221 is provided with a coating or a protrusion structure, so that during the contact process with the cable 3, the coating or protrusion structure can increase the friction force on the pressing surface 22131, further enhancing the positioning effect of the cable 3.

[0046] At this time, the cross-sectional area of ​​the limiting portion 22 is equivalent to or smaller than the cross-sectional area of ​​the first cavity 121 of the wire-passing cavity 12. At the same time, the cross-sectional area of ​​the limiting portion 22 is larger than the cross-sectional area of ​​the second cavity 122 of the wire-passing cavity 12.

[0047] Therefore, when the limiting portion 22 is installed in the cable passage cavity 12 and is passed from the first cavity 121 into the second cavity 122, the limiting portion 22 is squeezed by the inner wall of the second cavity 122, causing the elastic arm 221 of the limiting portion 22 to elastically deform toward the reserved space 220 and compress the cable 3. In this way, the cable 3 is fixed.

[0048] Preferably, a side of the free end 2213 facing away from the pressing surface 22131 is provided with a contact surface 22132, and the contact surface 22132 is configured to cooperate with the guide surface 120 and slide along the guide surface 120. In this embodiment, the contact surface 22132 can completely fit with the guide surface 120, so that the limiting portion 22 can easily slide along the guide surface 120 from the first cavity 121 into the second cavity 122. In other embodiments, the guide surface 120 can also be configured as a guide member removably arranged on the inner wall surface of the wire passing cavity 12, through which the wire passing cavity 12 can be divided into a first cavity 121 and a second cavity 122 with different cross-sectional areas. Preferably, at least a portion of the shape of the guide member is adapted to the contact surface 22132, so as to allow the limiting portion 22 to slide along the guide member from the first cavity 121 into the second cavity 122.

[0049] Please combine Figure 6 As shown, in this embodiment, the elastic arm 221 includes a first elastic arm 2211 and a second elastic arm 2212 that are arranged opposite to each other. A reserved space 220 is formed between the first elastic arm 2211 and the second elastic arm 2212. One end of the first elastic arm 2211 is connected to the base 21, and the other end is elastically pressed against one side of the cable 3. One end of the second elastic arm 2212 is connected to the base, and the other end is elastically pressed against the other side of the cable 3. In other words, when the limiting portion 22 is located in the second cavity 122, the two elastic arms 221 will squeeze the cable 3 in different directions (for example, two directions opposite to each other), which can position the cable 3 while making the cable 3 more securely fixed.

[0050] Preferably, the first elastic arm 2211 and the second elastic arm 2212 extend to different lengths in the extension direction of the limiting portion 22. This allows the cable 3 to be twisted when secured, further improving the cable 3's pull-out resistance. Of course, in other embodiments, the first elastic arm 2211 and the second elastic arm 2212 can also extend to the same length, which facilitates manufacturing.

[0051] The base 21 of the wire pressing member 2 is provided with a positioning groove 211. The positioning groove 211 is aligned with the positioning hole 14 on the carrier 1, so that the positioning member 4 can be simultaneously passed through the positioning hole 14 and the positioning groove 211 to secure the wire pressing member 2 to the carrier 1. The positioning member 4 is preferably a screw, and the positioning groove 211 and the positioning hole 14 are threaded holes.

[0052] In this embodiment, after the cable 3 is installed on the wire pressing member 2 , the cross-sectional area of ​​the limiting portion 22 of the wire pressing member 2 is larger than the cross-sectional area of ​​the second cavity 122 and smaller than the cross-sectional area of ​​the first cavity 121 .

[0053] Therefore, when no external force is applied to the wire pressing member 2, a gap is left between the base 21 of the wire pressing member 2 and the base 10 of the carrier 1, and the limiting portion 22 of the wire pressing member 2 will be in the first cavity 121. When the positioning member 4 passes through the positioning hole 14 and the positioning groove 211 at the same time, and applies a force toward the base 10 of the carrier 1 so that the base 21 of the wire pressing member 2 is fixed on the base 10 of the carrier 1, the limiting portion 22 of the wire pressing member 2 will be pushed and moved from the first cavity 121 toward the second cavity 122. In this way, the cable 3 can be fixed while the carrier 1 and the wire pressing member 2 are fixed, which further simplifies the operation steps and makes the operation easier.

[0054] Of course, during installation, the limiting portion 22 of the wire pressing member 2 can be directly pushed into the second cavity 122 and then fixed with the positioning member 4. These can be freely selected according to the installer's preferences and are not limited to this.

[0055] Based on the wire pressing assembly 100 , the present invention further provides a lamp having the wire pressing assembly 100 . The lamp may be a linear lamp, a downlight, a candle lamp, etc. This embodiment does not limit the specific type of the lamp.

[0056] See also Figures 5 to 7 As shown, in this embodiment, the carrier 1 is a radiator, the wire pressing member 2 is a light source bracket, and the base 21 of the light source bracket is provided with an assembly space 210 for installing the light source board 5. Since the reserved space 220 on the limiting portion 22 passes through the base 21, the base 21 is correspondingly provided with a wire outlet 212 connecting the wire cavity 12 and the receiving cavity 11. The cable 3 is mechanically and electrically connected to the light source board 5 after passing through the wire hole 13, the wire cavity 12, the reserved space 220 and the wire outlet 212. Generally, the radiator is an aluminum structural member, which can improve the heat dissipation efficiency of the radiator.

[0057] In summary, the wire pressing assembly 100 and the lamp of the present invention are provided with a receiving cavity 11 and a wire passing cavity 12 that are interconnected in the carrier 1, so that the base 21 of the wire pressing member 2 is assembled in the receiving cavity 11 and the limiting portion 22 of the wire pressing member 2 is accommodated in the wire passing cavity 12; in addition, an elastic arm 221 connected to the base 21 is provided on the limiting portion 22 of the wire pressing member 2, so that the cable 3 will abut against the elastic arm 221 after passing through the reserved space 220 of the limiting portion 22, and the elastic arm 221 can be elastically deformed away from the cable 3; and when the limiting portion 22 is accommodated in the wire passing cavity 12, the elastic arm 221 abuts against the inner wall surface of the wire passing cavity 12 and squeezes the cable 3. In this way, the wire pressing and fixing of the cable 3 is achieved, the installation method is simple, and it is practical.

[0058] 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, those skilled in the art should understand 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.
