Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an electric connection device and a lighting lamp. Background Art

[0002] The existing ceiling lamp wiring method on the market is mainly to pass the mains wire through the wire hole reserved in the mounting plate to the inside of the lamp body, and then connect the wires to the terminal inside the lamp body. Since the mains wire on the ceiling needs to pass through the mounting plate, the diameter of the wire hole on the mounting plate is generally much larger than the wire diameter to ensure that the user can pass the wire through the wire hole.

[0003] However, the gap between the threading hole and the mains wire can easily allow mosquitoes to enter, affecting the lighting effect. Moreover, before fixing the installation plate on the ceiling, the user needs to stand on a ladder, hold the installation plate with one hand, and hold the mains wire in the other hand to pass the wire through the threading hole. The large-sized installation plate is very heavy, and the threading hole is generally located in the middle of the installation plate. The installation plate is too large, and the position of the threading hole is difficult to find. In addition, the mains wire extension length reserved for some ceilings is very short. It is also very difficult for professional installers to pass the wire through the installation plate, resulting in complicated connection operations between the mains wire and the ceiling lamp.

[0038] In order to make the purpose, technical solution and advantages of this embodiment clearer, the technical solution in this embodiment will be clearly and completely described below in conjunction with the drawings in this embodiment. Obviously, the described embodiment is a part of the embodiment, not all of the embodiments. Based on the embodiments in this embodiment, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this embodiment.

[0039] like Figures 1 to 6 As shown, the electrical connection device of the embodiment of the utility model includes: a housing 1 and a conductive component 2.

[0040] Among them, the shell 1 is provided with a storage space 13, and adjacent first side wall 14 and second side wall 15. The first side wall 14 is provided with a wire opening 112 connected to the storage space 13, and the second side wall 15 is provided with a pressing opening 113 connected to the storage space 13. The outer wall of the shell 1 is also provided with a pressing portion 122, and at least a part of the pressing portion 122 is movably arranged in the pressing opening 113. In other words, the pressing portion 122 can pass through the pressing opening 113 and extend into the interior of the storage space 13.

[0041] In addition, the conductive component 2 is arranged inside the storage space 13, and the conductive component 2 includes a clamping spring 22 and a contact spring 21 connected to each other. The clamping spring 22 encloses a wire clamping space 221. The clamping spring 22 is also provided with a threading port 222 connected to the wire clamping space 221, and the threading port 222 corresponds to the wire passing port 112. The shell 1 is also provided with an electrical connection port 111 on the side facing the contact spring 21, and at least part of the contact spring 21 is exposed at the electrical connection port 111.

[0042] The shell 1 may be a symmetrical structure. For example, the shell 1 includes a first arcuate side wall, a first side wall 14, a second side wall 15, a third side wall, a second arcuate side wall, a fourth side wall, a fifth side wall and a sixth side wall connected end to end in sequence.

[0043] Among them, the pressing portion 122 has a first position and a second position relative to the clamping spring piece 22. When the pressing portion 122 is in the first position, the pressing portion 122 abuts against the clamping spring piece 22, and the clamping line space 221 is in an extrusion posture. When the pressing portion 122 is in the second position, the pressing portion 122 is separated from the clamping spring piece 22, and the clamping line space 221 is in an original posture.

[0044] It should be noted that the external wire is sequentially passed through the wire passing opening 112 and the wire threading opening 222 and then extends into the wire clamping space 221, the pressing portion 122 abuts against the clamping spring piece 22, and the wire clamping space 221 is in an extruded posture. At this time, the external wire is clamped between the first inner side wall and the second inner side wall of the wire clamping space 221, wherein the side of the clamping spring piece 22 where the wire threading opening 222 is provided is defined as the third inner side wall, the first inner side wall and the second inner side wall are adjacent to the third inner side wall, and the first inner side wall and the second inner side wall are arranged opposite to each other.

[0045] In the embodiment of the utility model, since the outer wall of the housing 1 is provided with a pressing portion 122 movably arranged at the pressing opening 113, the pressing portion 122 has a first position and a second position relative to the clamping spring piece 22. Therefore, when the pressing portion 122 is located at the second position, the pressing portion 122 is separated from the clamping spring piece 22, and the clamping space 221 is in the original posture. The external wire is sequentially passed through the wire passing opening 112 and the threading opening 222 and then extends into the clamping space 221. Then, when an external force acts on the pressing portion 122, the pressing portion 122 is pressed. 122 switches from the second position to the first position. At this time, the pressing portion 122 abuts against the clamping spring piece 22, and the wire clamping space 221 is in an extruded posture. The internal and external wires inserted into the wire clamping space 221 are fixed in the wire clamping space 221. At the same time, the external wires, the clamping spring piece 22 and the contact spring piece 21 are electrically connected. The light source module 5 can be electrically connected to the contact spring piece 21 through the electrical connection port 111 to complete the power supply. The operation is simple, safe and reliable, and can solve the problem that the current connection operation between the mains wires and the ceiling lamps is relatively complicated.

[0046] In an optional embodiment, if Figures 1 to 6 As shown, the pressing portion 122 includes a cantilever 1221 and a hook 1222 connected to each other. The hook 1222 is arranged on a side of the cantilever 1221 facing the pressing opening 113 . A slot 1131 matching the hook 1222 is arranged on an edge of the pressing opening 113 facing the clamping spring sheet 22 .

[0047] When the hook 1222 and the slot 1131 are connected, the hook 1222 abuts against the clamping spring sheet 22, and the clamping space 221 is in an extruded posture. When the hook 1222 and the slot 1131 are separated, the hook 1222 is away from the clamping spring sheet 22, and the clamping space 221 is in an original posture.

[0048] It should be noted that when the hook 1222 and the slot 1131 are separated, the hook 1222 is away from the clamping spring piece 22 and the wire clamping space 221 is in its original posture. At this time, the external wire can pass through the wire threading port 222. The external wire is successively passed through the wire passing port 112 and the wire threading port 222 and then extends into the wire clamping space 221, pushing the cantilever 1221 to connect the hook 1222 with the slot 1131. At this time, the hook 1222 abuts against the clamping spring piece 22, and the wire clamping space 221 is in an extruded posture. The external wires extending into the wire clamping space 221 are fixed in the wire clamping space 221.

[0049] In an optional embodiment, if Figures 2 to 6 As shown, the housing 1 includes a bottom plate 12 and a mounting seat 11 that are snap-fitted together, a wire-passing opening 112 and a pressing opening 113 are provided on the mounting seat 11, the central axis of the wire-passing opening 112 is arranged at an angle to the central axis of the pressing opening 113, and the pressing portion 122 is provided on the outer side wall of the bottom plate 12. Among them, the cantilever 1221 can be provided on the outer side wall of the bottom plate 12, the cantilever 1221 includes a bent portion and a horizontal portion, and the hook 1222 is provided on the side of the horizontal portion facing the pressing opening 113.

[0050] Among them, the base plate 12 and the mounting seat 11 can also be connected by fasteners. For example, a connecting column is provided at the center position of the mounting seat 11, the connecting column is provided with a first threaded hole, and the base plate 12 is provided with a second threaded hole. The fasteners are sequentially passed through the second threaded hole and the first threaded hole to connect the base plate 12 and the mounting seat 11.

[0051] It is understandable that the central axis of the wire passing opening 112 and the central axis of the pressing opening 113 can be arranged perpendicularly, and the pressing opening 113 is arranged close to the wire passing opening 112, so as to ensure the reliability of the connection of the external wire in the wire clamping space 221.

[0052] In an optional embodiment, if Figure 3 and Figure 4 As shown, a mounting groove 116 is provided on one side of the mounting seat 11 facing the bottom plate 12 , the wire passing opening 112 and the pressing opening 113 are both connected to the mounting groove 116 , and the clamping spring piece 22 is limitedly disposed inside the mounting groove 116 .

[0053] It should be noted that a mounting groove 116 is recessed on one side of the mounting seat 11 facing the base plate 12 , and the mounting groove 116 is adapted to the clamping spring piece 22 , and the clamping spring piece 22 is limited and fixed in the mounting groove 116 . In addition, the wire passing opening 112 and the pressing opening 113 correspond to two adjacent side walls of the clamping spring piece 22 , respectively.

[0054] In an optional embodiment, if Figure 3 and Figure 4As shown, the electrical connection port 111 is provided on the mounting base 11 , and a guide groove 114 is further provided on the side of the mounting base 11 facing the bottom plate 12 . The guide groove 114 is connected to the electrical connection port 111 , and the contact spring 21 is attached to the guide groove 114 so that part of the contact spring 21 is exposed at the electrical connection port 111 .

[0055] It should be noted that part of the contact spring piece 21 can be attached to the guide groove 114, and another part of the contact spring piece 21 is exposed at the electrical connection port 111. That is to say, by setting the guide groove 114, the stability of the contact spring piece 21 can be improved to prevent the contact spring piece 21 from shaking relative to the mounting seat 11, thereby affecting the electrical connection effect and causing poor contact.

[0056] In an optional embodiment, if Figure 3 and Figure 4 As shown, the guide groove 114 extends obliquely from the side of the mounting seat 11 facing the bottom plate 12 to the side of the mounting seat 11 facing away from the bottom plate 12 .

[0057] It can be understood that the depth of the guide groove 114 gradually increases from the side of the mounting base 11 toward the base plate 12 to the side of the mounting base 11 away from the base plate 12. That is to say, when the contact spring 21 is attached to the guide groove 114, the contact spring 21 gradually moves away from the base plate 12, thereby facilitating electrical connection with the light source module 5.

[0058] In an optional embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a limiting column 115 is provided on one side of the mounting base 11 facing the bottom plate 12 , and a corresponding limiting hole is provided on the contact spring 21 , and the limiting column 115 is passed through the limiting hole.

[0059] In actual applications, a limiting column 115 is also provided on the side of the base plate 12 facing the mounting seat 11, and the contact spring 21 is provided with a corresponding limiting hole, so as to ensure that the contact spring 21 can be stably fixed between the mounting seat 11 and the base plate 12, so as to prevent the contact spring 21 from shaking in the horizontal direction relative to the shell 1, thereby affecting the electrical connection effect and causing poor contact.

[0060] In an optional embodiment, if Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the contact spring 21 includes a spring body 211, a first contact portion 212 and a second contact portion 213. The spring body 211 is connected to the clamping spring 22. The first contact portion 212 and the second contact portion 213 are respectively arranged on opposite sides of the spring body 211. The shell 1 is provided with two electrical connection ports 111 corresponding to the first contact portion 212 and the second contact portion 213 respectively on one side facing the contact spring 21.

[0061] Exemplarily, two electrical connection ports 111 are provided on the side of the mounting base 11 facing the base plate 12, each electrical connection port 111 is connected to a corresponding guide groove 114, the first contact portion 212 is exposed at the corresponding electrical connection port 111, and the second contact portion 213 is exposed at the corresponding electrical connection port 111, wherein the first contact portion 212 and the second contact portion 213 are both electrically connected to the clamping spring clip 22 through the spring clip body 211.

[0062] It is understandable that the electrical connection component includes two conductive components 2, one of which corresponds to the positive electrode and the other corresponds to the negative electrode. In other words, when both the positive electrode and the negative electrode have two contact parts, multiple conduction states with the light source module 5 are added.

[0063] In addition, if Figures 1 to 10 As shown, the embodiment of the utility model further provides a lighting fixture, comprising: a bracket 3, a lampshade 4, a light source module 5 and the above-mentioned electrical connection device.

[0064] The lampshade 4 is provided with an installation space 41, the light source module 5 is provided in the installation space 41, the bracket 3 is detachably connected to the inner wall of the installation space 41, the electrical connection device is provided on the side of the bracket 3 facing the light source module 5, and the electrical contact 51 of the light source module 5 is penetrated through the electrical connection port 111 to abut against the contact spring 21. The electrical contact 51 can be a copper needle.

[0065] Specifically, the mounting seat 11 faces the side where the light source module 5 is located, and the bottom plate 12 is connected to the bracket 3 . In other words, the electrical connection port 111 faces the side where the light source module 5 is located.

[0066] It should be noted that the lampshade 4 includes a first part and a second part that are connected, the light source module 5 is arranged in the first part, the second part can be circular, and the inner wall of the second part is provided with multiple overlapping parts 42. For example, the inner wall of the second part is provided with four overlapping parts 42, and the four overlapping parts 42 are arranged at equal intervals along the circumferential direction of the second part, and the four overlapping parts 42 are located on the same horizontal plane.

[0067] In this way, the bracket 3 includes a fixed part 31 and a connecting part 32 connected to each other. The connecting part 32 is arranged on the peripheral side of the fixed part 31. The fixed part 31 is suitable for connecting to the top surface of the wall. The peripheral side of the connecting part 32 is provided with a locking part 321 adapted to the overlapping part 42. The locking part 321 is provided with a guide surface and a locking surface. The overlapping part 42 can be moved to the locking surface via the guide surface, thereby realizing the connection between the lampshade 4 and the bracket 3.

[0068] Exemplarily, when the number of the overlapping portions 42 is four, the number of the locking portions 321 is four, and the four locking portions 321 are arranged at equal intervals along the circumferential direction of the connecting portion 32 .

[0069] In an optional embodiment, if Figures 7 to 10 As shown, the outer wall of the shell 1 is provided with a clamping portion 1211, and the bracket 3 is provided with a clamping portion 311 adapted to the clamping portion 1211, and the bracket 3 and the shell 1 are detachably connected via the clamping portion 1211 and the clamping portion 311.

[0070] Specifically, the outer periphery of the bottom plate 12 is provided with a side plate 121, and the clamping portion 1211 is provided on the side plate 121. Correspondingly, the fixing portion 31 is provided with a clamping portion 311 on the side facing the bottom plate 12. For example, the clamping portion 1211 may be triangular, and the clamping portion 311 may be formed with an inverted V-shaped notch, so as to achieve the clamping engagement between the clamping portion 1211 and the clamping portion 311.

[0071] In the embodiment of the utility model, the bracket 3 is first installed on the top of the wall. After the bracket 3 is installed, the shell 1 of the electrical connection device is installed on the bracket 3. After the electrical connection device and the bracket 3 are installed, the external wires are connected to the clamping spring 22. Finally, the lampshade 4 is mechanically connected to the bracket 3. At the same time, the light source module 5 is electrically connected to the contact spring 21.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this embodiment, rather than to limit it. Although this embodiment has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
