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] Ceiling lamps are a type of lamps. As the name suggests, they are called ceiling lamps because the bottom of the lamp is completely attached to the ceiling when it is installed. Of course, if there is no ceiling, some ceiling lamps can also be installed directly on the top of the wall. Ceiling lamps are often used in various places such as homes, offices, and entertainment venues.

[0003] The existing wiring method of ceiling lamps on the market is mainly to pass the mains wire through the wire hole reserved in the installation 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 installation plate, the hole diameter of the wire hole on the installation plate is generally much larger than the wire diameter to ensure that the user can pass the wire through the wire hole. However, before fixing the installation plate on the ceiling, the user needs to stand on a ladder, holding the installation plate with one hand and holding the mains wire with the other hand to pass the wire through the wire hole. The large-sized installation plate is very heavy, and the wire hole is generally located in the middle of the installation plate. The size of the installation plate is too large, and the position of the wire hole is difficult to find. In addition, the mains power reserved on some ceilings is very short, and 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.

[0035] 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.

[0036] like Figures 1 to 7 As shown, the electrical connection device of the embodiment of the utility model includes: a housing 1 and a conductive component 2.

[0037] Among them, the shell 1 is provided with a storage space, and the side wall of the shell 1 is provided with a threading port 112 connected to the storage space, and the outer wall of the shell 1 is provided with a pressing portion 122 near the threading port 112, and at least part of the pressing portion 122 is movably provided in the threading port 112. In other words, the pressing portion 122 can pass through the threading port 112 and extend into the storage space.

[0038] In addition, the conductive component 2 includes a conductive sheet 22 and a clamping spring 21. The conductive sheet 22 is arranged in the storage space. The clamping spring 21 is arranged on the conductive sheet 22 and is close to the threading port 112. The clamping spring 21 is provided with a clamping space. The side of the clamping spring 21 facing the threading port 112 is provided with an openable and closable wire pressing port 215. The wire pressing port 215 is connected to the clamping space, and at least a portion of the wire pressing port 215 is arranged opposite to the threading port 112.

[0039] In actual application, the pressing portion 122 has a first position and a second position relative to the clamping spring sheet 21, and can switch between the first position and the second position. In the first position, the pressing portion 122 abuts against the clamping spring sheet 21, and the wire pressing opening 215 is in an open state. In the second position, the pressing portion 122 is separated from the clamping spring sheet 21, and the wire pressing opening 215 is in a closed state. In addition, the housing 1 is further provided with an electrical connection opening 111 on one side facing the conductive sheet 22, and at least a portion of the conductive sheet 22 is exposed at the electrical connection opening 111.

[0040] 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 threading port 112, when an external force acts on the pressing portion 122, the pressing portion 122 can abut against the clamping spring piece 21 located in the storage space and close to the threading port 112, and the pressing port 215 can be in an open state, and then the external wire can be successively passed through the threading port 112 and the pressing port 215 and then extend into the clamping space, and then when the external force is removed, the pressing portion 122 is closed. In this case, the pressing portion 122 is separated from the clamping spring piece 21, and the wire pressing port 215 is in a closed state. The external wire can be fixed in the clamping space, and the external wire is electrically connected to the clamping spring piece 21. At the same time, the external wire is electrically connected to the clamping spring piece 21 and the conductive sheet 22. The light source module can be electrically connected to the conductive sheet 22 through the electrical connection port 111 to complete 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 lamp is relatively complicated.

[0041] In an optional embodiment, if Figure 7 As shown, the clamping spring 21 includes a horizontal portion 211, an arc portion 212 extending from the horizontal portion 211, an inclined portion 213 extending from the arc portion 212, and a wire pressing portion 214 extending from the inclined portion 213, a wire pressing opening 215 is formed between the wire pressing portion 214 and the horizontal portion 211, and the wire pressing portion 214 can move relative to the horizontal portion 211.

[0042] Specifically, the horizontal portion 211, the arc-shaped portion 212, the inclined portion 213 and the wire pressing portion 214 enclose a wire clamping space, and a wire pressing opening 215 connected to the wire clamping space is formed between the wire pressing portion 214 and the horizontal portion 211. When the wire pressing portion 214 is in contact with the horizontal portion 211, the wire pressing opening 215 is in a closed state, and the external wire cannot pass through. When the wire pressing portion 214 is away from the horizontal portion 211, the wire pressing opening 215 is in an open state, and the external wire enters the wire clamping space through the wire pressing opening 215, and is clamped between the wire pressing portion 214 and the horizontal portion 211, thereby realizing mechanical and electrical connection between the external wire and the clamping spring 21.

[0043] The horizontal portion 211 , the arc-shaped portion 212 , the inclined portion 213 and the line pressing portion 214 may be integrally formed, for example, by sheet metal or injection molding.

[0044] In this way, when an external force acts on the pressing portion 122, the pressing portion 122 abuts against the wire pressing portion 214, the wire pressing portion 214 is away from the horizontal portion 211, and the wire pressing opening 215 can be in an open state. Then, the external wire can be successively passed through the wire threading opening 112 and the wire pressing opening 215 and then extended into the wire clamping space. When the external force is removed, the pressing portion 122 can be reset, the pressing portion 122 is separated from the wire pressing portion 214, the wire pressing portion 214 abuts against the horizontal portion 211, and the wire pressing opening 215 is in a closed state. At this time, the external wire is fixed in the clamping space, and the external wire is electrically connected to the clamping spring 21.

[0045] In an optional embodiment, if Figures 1 to 7 As shown, the housing 1 includes a bottom plate 12 and a mounting seat 11 that are snap-fitted together, a clamping spring 21 is disposed on the mounting seat 11, and a pressing portion 122 includes a cantilever portion 1221 and an abutting portion 1222 that are connected to each other, the cantilever portion 1221 is disposed at the edge of the bottom plate 12, and the abutting portion 1222 is disposed on the side of the cantilever portion 1221 that faces the threading port 112. In addition, in order to facilitate the insertion of external wires into the threading port 112, the cantilever portion 1221 is provided with a wire passing port 123 corresponding to the threading port 112. Among them, the mounting seat 11 is provided with a receiving groove 114, the clamping spring 21 is disposed inside the receiving groove 114, and the threading port 112 is communicated with the receiving groove 114.

[0046] Specifically, 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.

[0047] In actual application, when external force acts on the cantilever portion 1221, the cantilever portion 1221 can drive the abutting portion 1222 to move, the abutting portion 1222 abuts against the wire pressing portion 214, the wire pressing portion 214 is away from the horizontal portion 211, and the wire pressing opening 215 can be in an open state. Then, the external wire can be successively passed through the wire passing opening 123, the wire threading opening 112, and the wire pressing opening 215 and then extended into the wire clamping space. When the external force is removed, the cantilever portion 1221 can drive the abutting portion 1222 to reset, the abutting portion 1222 separates from the wire pressing portion 214, the wire pressing portion 214 abuts against the horizontal portion 211, and the wire pressing opening 215 is in a closed state. At this time, the external wire is fixed in the clamping space, and the external wire is electrically connected to the clamping spring 21.

[0048] In practical applications, the bottom plate 12, the cantilever portion 1221 and the abutting portion 1222 are integrally formed, for example, by sheet metal or injection molding.

[0050] Specifically, a wire groove 113 connected to the wire threading port 112 is provided on the outer periphery of the mounting seat 11, which can improve the threading efficiency of the external wires. The wire groove 113 provides a routing path for the external wires to prevent the external wires from being pulled when the user acts on the cantilever portion 1221, thereby affecting the connection reliability between the external wires and the clamping spring 21. The wire groove 113 can be open, for example, the wire groove 113 is a U-shaped groove.

[0055] In addition, a limiting column 116 is provided on the side of the mounting seat 11 facing the base plate 12, and a corresponding limiting hole is provided on the annular elastic sheet. The limiting column 116 is passed through the limiting hole to achieve the limitation of the annular elastic sheet and the mounting seat 11, which can improve the stability of the annular elastic sheet to prevent the annular elastic sheet from shaking relative to the mounting seat 11, thereby affecting the electrical connection effect and causing poor contact.

[0056] Exemplarily, two limiting columns 116 are provided on the side of the mounting seat 11 facing the base plate 12. The two limiting columns 116 can be arranged along the radial direction of the annular elastic sheet. Correspondingly, the annular elastic sheet is provided with two limiting holes.

[0057] In addition, a guide groove 115 communicating with the electrical connection port 111 is disposed on one side of the mounting base 11 facing the bottom plate 12 . A portion of the elastic sheet 222 is attached to the guide groove 115 , and the contact sheet 223 is exposed at the electrical connection port 111 .

[0058] It should be noted that, when the electrical connection port 111 includes a first arc-shaped electrical connection port and a second arc-shaped electrical connection port, the guide groove 115 includes a first guide groove and a second guide groove, the first guide groove is arranged at the first arc-shaped electrical connection port, and the second guide groove is arranged at the second arc-shaped electrical connection port.

[0064] It should be noted that the lampshade includes a first part and a second part that are connected, the light source module 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.
