Description

Technical Field

[0001] This invention relates to the field of lighting assembly technology, specifically to positioning devices and lighting fixtures. Background Technology

[0002] In the manufacturing and assembly process of lighting fixtures, the electrical connection between the motherboard and the power supply is a crucial step in ensuring the normal power supply and stable operation of the lighting fixtures. Currently, there are two main connection methods commonly used in the industry: wire soldering and direct insertion of solid wires into the motherboard terminals.

[0003] One method involves directly inserting the power supply wire into a pre-designed terminal on the motherboard. This establishes electrical contact between the wire and the terminal. However, this method requires the wire to be perfectly aligned with the terminal during insertion, making manual assembly difficult and inefficient. Furthermore, if the wire is misaligned during insertion, it may fail to make proper contact, leading to poor contact, excessive contact resistance, unstable power supply, or even wire detachment and malfunction of the lighting fixture. Summary of the Invention

[0004] On the one hand, the present invention provides a positioning device to solve the problems of high operational difficulty, low installation efficiency and poor connection reliability when the existing connection between the motherboard and the power supply is made by directly inserting a hard wire.

[0005] This invention provides a positioning device suitable for assembly onto a lamp body, comprising:

[0006] The positioning plate has an insertion hole suitable for wires to pass through; The positioning structure, located on the positioning plate, includes a first guide slope along a first direction and a second guide slope along a second direction, wherein the first direction and the second direction are different; When the positioning device is assembled onto the lamp body, the first guide slope is adapted to guide the lamp body to move relative to the positioning plate in a first direction, and the second guide slope is adapted to guide the lamp body to move relative to the positioning plate in a second direction, until the insertion hole corresponds to the terminal on the lamp body.

[0007] Beneficial Effects: The positioning device provided by this invention, when assembled onto the lamp body, allows the lamp body to move simultaneously relative to the positioning plate along the first and second directions under the guidance of the first and second guide inclined surfaces of the positioning structure, due to the positioning structure on the positioning plate. This automatically corrects the relative position of the terminals on the lamp body and the insertion holes on the positioning plate, enabling the wire to smoothly connect to the terminals on the lamp body in a certain direction, ensuring insertion accuracy and efficiency, and facilitating operation. Furthermore, because the end of the wire achieves precise docking with the terminal on the lamp body, it ensures that the wire remains firmly fixed in the terminal when the product is subjected to external forces, such as accidental drops, preventing misalignment or stress and ensuring product reliability. It also prevents other components on the lamp body from falling off, providing a certain degree of protection, extending the product's service life, preventing accidents, and ensuring personal safety.

[0008] In one optional embodiment, a hole seat is formed on the positioning plate, and an insertion hole is provided in the hole seat. The insertion hole includes a first guide hole and a second guide hole that are interconnected. Both the first guide hole and the second guide hole are tapered holes. The second guide hole is located away from the positioning plate, and the first guide angle of the first guide hole is greater than the second guide angle of the second guide hole. The lamp body is provided with mounting holes suitable for assembly with the mounting base.

[0009] The socket design also guides the insertion of the wire. Two guide holes of different diameters are provided along the insertion direction to further guide the wire. Since the wire initially deviates significantly from the lamp body terminal, the larger diameter first guide hole provides some adjustment margin. As the wire gradually approaches the lamp body terminal, precise alignment is required, hence the smaller diameter second guide hole. The combination of these two design improves insertion accuracy while maintaining efficiency. The guide angle of the first guide hole is greater than that of the second guide hole, facilitating gradual positioning and reducing the precision requirements for wire insertion, thus aiding in automated production.

[0010] In one optional embodiment, the guide angle of the first guide hole is no more than 45° and greater than 30°; the guide angle of the second guide hole is no more than 30° and greater than 10°.

[0011] The guiding angles of both the first and second guide holes are acute angles, meaning the angles are relatively small, which is sufficient to provide the corresponding guiding function.

[0012] In one optional embodiment, the insertion holes include at least two arranged side by side, a hole seat is provided between two adjacent insertion holes with a first guide plate, a first guide slope is provided on the first guide plate, a second guide plate is provided around the hole seat, the second guide plate is arranged perpendicularly to the first guide plate, and a second guide slope is provided on the second guide plate; the mounting hole includes a first mounting part that is assembled with the first guide plate and a second mounting part that is assembled with the second guide plate.

[0013] Two insertion holes correspond to the positive and negative wires, respectively. Both wires can pass through these holes simultaneously to connect to the corresponding terminals on the lamp body, further improving installation efficiency. A first guide slope is located on the first guide plate, which simultaneously guides both the positive and negative wires in the first direction, simplifying the device structure. Furthermore, the first and second guide slopes are distributed around the insertion holes, providing guidance while making the entire device more compact and reducing space requirements. Because the areas of the first and second guide plates are small, the connection area with the positioning plate is also small. To ensure reliable connection, a hole seat is added to increase the contact area between the first and second guide plates and the positioning plate, while avoiding the increased cost associated with directly machining the first and second guide slopes on the positioning plate, which would require increasing the thickness of the positioning plate.

[0014] In one optional embodiment, the inclination angle of the first guide ramp is no more than 45° and greater than 10°; the inclination angle of the second guide ramp is no more than 45° and greater than 10°.

[0015] The inclination angles of both the first and second guide ramps are acute angles. As the positioning structure is inserted into the mounting hole on the lamp body, the relative displacement between the lamp body and the positioning plate becomes smaller and smaller, thereby accurately aligning the insertion hole with the terminal on the lamp body and improving installation efficiency.

[0016] In one alternative embodiment, the positioning plate is provided with a second fixing structure for connecting and fixing to the lamp body.

[0017] The second fixing structure ensures a reliable connection between the positioning plate and the lamp body, preventing them from easily separating and being damaged when subjected to external forces.

[0018] In one alternative embodiment, the positioning plate has a positioning surface that abuts against the surface of the lamp body after the positioning structure is connected to the lamp body.

[0019] The positioning surface of the positioning plate abuts against the surface of the lamp body, making the connection between the positioning plate and the lamp body more stable.

[0020] On the other hand, the present invention also provides a lamp, including a lamp body and a positioning device, wherein the positioning device is assembled to the lamp body.

[0021] In one optional embodiment, the lamp body includes: a lamp holder having a first fixing structure; a main board disposed on the lamp holder, the main board having mounting holes adapted to the positioning structure, and terminals disposed on a surface of the mounting holes facing away from the positioning device; when the second fixing structure of the positioning device is connected to the first fixing structure, the positioning structure is inserted into the mounting hole, the first guide slope is adapted to guide the main board to move relative to the positioning plate in a first direction, and the second guide slope is adapted to guide the main board to move relative to the positioning plate in a second direction, until the insertion hole corresponds to the terminals on the main board.

[0022] The positioning device and the main board are effectively connected through the cooperation of the positioning structure and mounting holes. The connection method is simple and easy to operate, ensuring that the positions of the two remain unchanged when the lamp is dropped or vibrated. This ensures that the wires will not come loose due to external force after being inserted into the terminal, thus improving the reliability of the electrical connection.

[0023] In one optional embodiment, the motherboard and the lamp holder have a first assembly gap in a first direction, and the motherboard and the lamp holder have a second assembly gap in a second direction; correspondingly, the guiding distance of the first guide ramp is at least half of the first assembly gap, and the guiding distance of the second guide ramp is at least half of the second assembly gap.

[0024] Because the motherboard and the lamp holder have assembly gaps, i.e. installation allowances, in both the first and second directions, and the first and second guide ramps guide the motherboard toward the positioning plate, this ensures that the motherboard can be centered relative to the lamp holder under the adjustment of the positioning device.

[0025] In one alternative embodiment, the terminal has a third guide bevel adapted to guide wire insertion.

[0026] The third guide bevel on the terminal further serves to guide the wire to connect quickly and accurately. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The following is combined Figures 1 to 7 Embodiments of the present invention are described.

[0032] According to an embodiment of the present invention, a positioning device is provided, suitable for assembly onto a lamp body 2, comprising: Positioning plate 1 has an insertion hole 102 suitable for wires to pass through; The positioning structure 3 is disposed on the positioning plate 1 and includes a first guide slope 301 along a first direction and a second guide slope 302 along a second direction, wherein the first direction and the second direction are different; When the positioning device is assembled onto the lamp body 2, the first guide slope 301 is adapted to guide the lamp body 2 to move relative to the positioning plate 1 in a first direction, and the second guide slope 302 is adapted to guide the lamp body 2 to move relative to the positioning plate 1 in a second direction, until the insertion hole 102 corresponds to the terminal 4 on the lamp body 2.

[0033] like Figure 1 and Figure 2As shown, the positioning plate 1 and the positioning structure 3 are integrally injection molded and can be made of plastic, which is convenient to process and has a low cost. The positioning plate 1 is a cuboid, so in this embodiment, the first direction can be the length direction of the positioning plate 1, and the second direction can be the width direction of the positioning plate 1. In this case, the first direction and the second direction are perpendicular to each other. Of course, the positioning plate 1 can also be a cube or other shapes, and the included angle between the first direction and the second direction can also be an acute angle or an obtuse angle, without specific limitations. Multiple insertion holes 102 can be set as needed. For example, in this example, two sets are set, for a total of four insertion holes 102. The two sets of insertion holes 102 are spaced apart along the length direction of the positioning plate 1 to ensure the uniformity of force during connection. The first guide slope 301 and the second guide slope 302 are both inclined downward from the outer edge of the positioning plate 1 towards the center, so as to guide the lamp body 2 to make fine adjustments relative to the positioning plate 1 in the first direction and the second direction by means of tangential component force. At least one first guide slope 301 and the second guide slope 302 are provided, so as to guide the center of the terminal 4 of the lamp body 2 to align with the center of the insertion hole 102 of the positioning plate 1 from two mutually perpendicular directions when the positioning plate 1 moves toward the lamp body 2, thereby ensuring the accuracy of wire insertion.

[0034] like Figure 1 As shown, the positioning structure 3 is distributed close to the insertion hole 102. Of course, the positioning structure 3 can also be set between the two sets of insertion holes 102, or at the edge of the positioning plate 1. No specific restrictions are made here.

[0035] The positioning structure 3 is positioned as close as possible to the insertion hole 102. This way, when the wire passes through the insertion hole 102, it can be guided and positioned by the positioning structure 3 immediately, which further improves the timeliness and effectiveness of positioning. At the same time, the positioning structure 3 is set around the outer periphery of the insertion hole 102. Since the wire is usually made of flexible metal, it also plays a certain limiting role for the wire, preventing the wire from deforming too much under its own action and affecting the insertion efficiency.

[0036] In one embodiment, a hole seat 103 is formed on the positioning plate 1, and an insertion hole 102 is provided on the hole seat 103. The insertion hole 102 includes a first guide hole and a second guide hole that are interconnected. Both the first guide hole and the second guide hole are tapered holes. The second guide hole is located away from the positioning plate 1, and the first guide angle of the first guide hole is greater than the second guide angle of the second guide hole. The lamp body 2 is provided with a mounting hole 202 suitable for assembly with the hole seat 103.

[0037] The insertion hole 102 and the hole seat 103 are integrally formed by injection molding. Because the hole seat 103 extends a certain length away from the positioning plate 1, a mounting hole 202 is provided on the lamp body 2 to assemble with the hole seat 103. This ensures that after the positioning plate 1 and the lamp body 2 are installed, the hole seat 103 is precisely located in the mounting hole 202, reducing the overall height of the device while ensuring assembly reliability. Figure 1 and Figure 4 As shown, the mounting base 103 includes a column and a boss connected together, which are integrally formed. A channel allowing wires to pass through is provided in the center. A first guide hole is located on the column, and a second guide hole is located at the smaller end of the boss, i.e., opposite to it. Both the first and second guide holes are tapered holes, and their diameter decreases as they approach the lamp body 2. In this embodiment, the first guide hole, the channel, and the second guide hole together constitute the wire insertion hole 102. Figure 5 The guide angle is the angle formed by the inclined surface of the guide hole and the vertical direction, where α is the first guide angle.

[0038] In one embodiment, the guide angle of the first guide hole is no more than 45° and greater than 30°; the guide angle of the second guide hole is no more than 30° and greater than 10°.

[0039] When both the first and second guide holes have small acute angles, the wire can be guided quickly and accurately to the predetermined position. The guide angles of the first and second guide holes can be flexibly adjusted according to the diameter of the wire, without specific limitations.

[0040] In one embodiment, the insertion hole 102 includes at least two arranged side by side, and the hole seat 103 is provided with a first guide plate 303 between two adjacent insertion holes 102. A first guide slope 301 is provided on the first guide plate 303, and a second guide plate 304 is provided around the hole seat 103. The second guide plate 304 is arranged perpendicularly to the first guide plate 303, and the second guide slope 302 is provided on the second guide plate 304. The mounting hole 202 includes a first mounting part 2021 that is assembled with the first guide plate 303 and a second mounting part 2022 that is assembled with the second guide plate 304.

[0041] Because terminal 4 needs to connect both the positive and negative wires simultaneously, the two insertion holes 102 are placed close together to make the entire device more compact. To prevent short circuits, a first guide plate 303 is added between the two adjacent insertion holes 102. Since the first and second directions are perpendicular, and the space on the positioning plate 1 is limited, the first guide slope 301 is placed at the first guide plate 303, maximizing space utilization. To ensure accurate guidance, the second guide slope 302 is placed as far away from the first guide slope 301 as possible, and is therefore perpendicular to the first guide plate 303. This ensures that the intersection of the extension lines of the first guide slope 301 and the second guide slope 302 lies on the center line of the two insertion holes 102, resulting in more precise positioning. Figure 3 and Figure 7 As shown, the mounting hole 202 is provided with a first mounting part 2021 and a second mounting part 2022. Specifically, the first mounting part 2021 and the second mounting part 2022 can be two mounting holes with mutually perpendicular extension directions.

[0042] Specifically, there are two first guide slopes 301 symmetrically arranged along the first direction, and the second guide slopes 302 are arranged away from the first guide plate 303. The second guide slopes 302 of a pair of second guide plates 304 are symmetrically arranged relative to the first guide plate 303.

[0043] like Figure 1 As shown, two insertion holes 102 are arranged side by side along the width direction of the positioning plate 1. The extension length of the hole seat 103 towards the lamp body 2 is less than the extension length of the first guide plate 303 and the second guide plate 304 towards the lamp body 2, so that the first guide slope 301 and the second guide slope 302 are exposed. At the same time, the insertion space for two wires is formed between the first guide plate 303 and the two second guide plates 304, which plays a certain limiting role. Specifically, the first guide plate 303 is an isosceles trapezoidal plate, with the two sides forming the first guide slope 301. The second guide plate 304 is a right-angled trapezoidal plate, with the right-angled side connected and fixed to the positioning plate 1, the inclined side forming the second guide slope, and the lower base connected and fixed to the outer wall of the hole seat 103. In addition, in order to further improve the connection strength, a reinforcing rib plate 305 is also provided on the upper base of the right-angled trapezoidal plate, and the reinforcing rib plate 305 is set perpendicular to the right-angled trapezoidal plate.

[0044] As an alternative implementation, the two insertion holes 102 can also be arranged side by side along the length of the positioning plate 1, in which case the positions of the first guide plate 303 and the second guide plate 304 are adjusted accordingly. Alternatively, the first guide slope 301 and the second guide slope 302 can be directly machined onto the outer wall of the hole seat 103; however, this would be more difficult to machine due to the complex shape of the hole seat 103. Furthermore, a pair of first guide plates 303 can also be arranged opposite each other and connected to the outer wall of the hole seat 103.

[0045] The arrangement of the two first guide slopes 301 on the first guide plate 303 satisfies the positioning requirements without increasing the space occupied by the device; the two second guide plates 304 are arranged opposite each other, which further improves the positioning accuracy without affecting the simultaneous insertion of the positive and negative wires.

[0046] As an alternative implementation, the insertion hole 102 includes two arranged side by side, and a first guide plate 303 is provided between two adjacent insertion holes 102. A first guide slope 301 is provided on the first guide plate 303. A pair of second guide plates 304 are provided opposite to each other around the insertion hole 102. The pair of second guide plates 304 are arranged perpendicular to the first guide plate 303. The second guide slope 302 is provided on the second guide plate 304. The mounting hole 202 includes a first mounting hole adapted to the first guide plate 303 and a second mounting hole adapted to the second guide plate 304.

[0047] The first guide plate 303 and the second guide plate 304 are directly set around the insertion hole 102, which makes processing more convenient and occupies less space. The setting of the first assembly hole and the second assembly hole on the lamp body 2 facilitates the precise assembly and positioning with the first guide plate 303 and the second guide plate 304.

[0048] In one embodiment, the tilt angle of the first guide slope 301 is no more than 45° and greater than 10°; the tilt angle of the second guide slope 302 is no more than 45° and greater than 10°.

[0049] The inclination angles of the first guide slope 301 and the second guide slope 302 can be flexibly set according to actual needs, and no specific restrictions are imposed here. Preferably, the inclination angles of the first guide slope 301 and the second guide slope 302 are equal and both are small acute angles. This way, when the positioning plate 1 moves toward the lamp body 2, the movement range of the lamp body 2 will not be too large, and the adjustment will be more efficient.

[0050] In one embodiment, the positioning plate 1 is provided with a second fixing structure 104, which is used to connect and fix with the lamp body 2.

[0051] like Figure 1 , Figure 3 and Figure 4 As shown, a second fixing structure 104 is provided on each of the two long edges of the positioning plate 1, and correspondingly, a first fixing structure 201 is provided on each of the two long edges of the lamp body 2. Specifically, the first fixing structure 201 is a slot, and the second fixing structure 104 is an elastic buckle. The elastic buckle is engaged in the slot under the action of external force, thereby fixing the position of the positioning plate 1 and the lamp body 2. Of course, the positions of the elastic buckle and the slot can be interchanged, and there can be multiple of them; no specific limitation is made here.

[0052] In one embodiment, the positioning plate 1 has a positioning surface 101, which is abutted against the surface of the lamp body 2 after the positioning structure 3 is connected to the lamp body 2.

[0053] The present invention also provides a lamp, including a lamp body 2 and a positioning device, wherein the positioning device is assembled to the lamp body 2.

[0054] In one embodiment, the lamp body 2 includes: a lamp holder 204 having a first fixing structure 201; a main board 203 disposed on the lamp holder 204, the main board 203 having a mounting hole 202 adapted to the positioning structure 3, and a terminal 4 disposed on a surface of the mounting hole 202 facing away from the positioning device; when the second fixing structure 104 of the positioning device is connected to the first fixing structure 201, the positioning structure 3 is inserted into the mounting hole 202, the first guide slope 301 is adapted to guide the main board 203 to move relative to the positioning plate 1 in a first direction, and the second guide slope 302 is adapted to guide the main board 203 to move relative to the positioning plate 1 in a second direction, until the insertion hole 102 corresponds to the terminal 4 on the main board 203.

[0055] like Figure 4 and Figure 6 As shown, the main board 203 is a long strip with multiple mounting holes 202 spaced along its length. Each mounting hole 202 corresponds to a positioning structure 3 of a positioning device. When a wire is inserted into the insertion hole 102, the positioning device moves synchronously toward the main board 203, meaning the positioning structure 3 inserts into the mounting hole 202 of the main board 203. A terminal 4 is fixed to the surface of the mounting hole 202 facing away from the positioning device. The terminal 4 is in the shape of an inverted "V". After the positioning device is installed in place, the end of the wire is smoothly electrically connected to the terminal 4. Then, the lamp housing is snapped onto the main board 203 to complete the installation. Of course, the number of positioning devices can be flexibly adjusted according to the length of the main board 203 and the number of wires to be connected; no specific limitation is made here. The main board 203 is equipped with an LED light. By adjusting the positioning of the positioning device, the LED light can be ensured to be located in the center of the main board 203, which is more aesthetically pleasing.

[0056] The positioning device and the main board 203 are effectively connected through the positioning structure 3 and the mounting hole 202. The connection method is simple and easy to operate. Furthermore, due to the precise alignment of the wires and terminals, the lamp housing, positioning device, and main board 203 form a relatively stable integrated structure. This ensures that the positions of the three components remain unchanged even if the lamp is dropped or vibrated. This also ensures that the wires, once inserted into the terminal 4, will not shift or even come out due to external force, guaranteeing the reliability of the electrical connection. Simultaneously, it avoids damage to the fixing structure between the main board 203 and the lamp holder 204 caused by severe impacts, as well as the detachment or damage to electronic components on the main board 203, reducing the degree of damage to the lamp, extending the product's lifespan, and preventing safety accidents such as short circuits and leakage caused by electrical connection failures, thus reducing threats to the personal and property safety of users.

[0057] In one embodiment, the motherboard 203 and the lamp holder 204 have a first assembly gap in a first direction, and the motherboard 203 and the lamp holder 204 have a second assembly gap in a second direction; correspondingly, the guiding distance of the first guide slope 301 is at least half of the first assembly gap, and the guiding distance of the second guide slope 302 is at least half of the second assembly gap.

[0058] In one embodiment, terminal 4 has a third guide bevel adapted to guide wire insertion.

[0059] like Figure 6 As shown, a third guide slope is provided at the bottom center of terminal 4, and the inclination angle of the third guide slope can be flexibly set according to the diameter of the wire.

[0060] In a specific assembly and implementation scenario of a lighting fixture First, connect the motherboard 203 to the lamp holder 204; Then, the positioning device is engaged with the slot of the lamp holder 204, so that the hole seat 103 is inserted into the corresponding mounting hole 202 of the main board 203. The first guide slope 301 cooperates with the corresponding first assembly part 2021, and the second guide slope 302 cooperates with the corresponding second assembly part 2022, so that the main board 203 is centered relative to the lamp holder 204, and the insertion hole 102 corresponds to the terminal 4. Next, connect the cover plate to the lamp holder 204. The cover plate is located on the upper part of the main board 203, and the holes in the cover plate correspond to the insertion holes 102. Then, the wire passes through the cover hole and the insertion hole 102 in sequence and is connected to the terminal 4.

[0061] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
