Description

Technical Field

[0001] This utility model relates to the field of LED lighting equipment technology, and in particular to an adapter for LED lamps. Background Technology

[0002] In the field of LED lighting, adapters serve as key connecting components between LED luminaires and external electronic control components. Their core function is to enable a detachable electrical connection between the two, thereby meeting the flexible adaptation requirements of LED luminaires to external control components in different application scenarios.

[0003] However, existing technologies, such as Chinese patent application CN222085952U, describe a waterproof adapter for LED lighting fixtures, which includes a main body and a base body. The main body and the base body are detachably connected, and the base body is electrically connected to the LED lighting fixture. The main body has a boss with a conductive ring on it. The base body has a cavity connected to the boss. A contact terminal is provided inside the cavity, and the boss is placed inside the cavity. The conductive ring is electrically connected to the contact terminal. By providing the conductive ring and contact terminal, the problem of deformation and poor contact caused by the exposed pin design can be solved.

[0004] However, during use, it was found that this device relies solely on the friction of the threaded pair to achieve a detachable connection between the boss and the cavity. On one hand, its anti-loosening capability is weak, making it difficult to adapt to the complex operating environment of LED lights. Since LED lights are often used in outdoor lighting, industrial site lighting, and other scenarios where vibration interference is prevalent, the friction between the threaded pairs gradually weakens under long-term vibration, leading to loosening of the threaded connection and subsequent relative displacement between the boss and the cavity. This displacement not only disrupts the stable contact between the conductive ring and the contact terminal, causing poor electrical contact and affecting the normal power supply and control signal transmission of the LED lights, but may also increase the sealing gap between the boss and the cavity, compromising the integrity of the original waterproof and dustproof structure. This allows external moisture, dust, and other impurities to enter the adapter, further increasing the risk of damage to electrical components. On the other hand, this connection method has poor assembly consistency, heavily relying on the operator's experience and skill level. Different operators, or even the same operator at different assembly stages, may have varying degrees of control over the thread engagement torque. Utility Model Content

[0005] The purpose of this invention is to solve the problems of weak anti-loosening ability and poor assembly consistency in existing threaded connections.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adapter for LED lamps, comprising a male adapter terminal and a female adapter terminal; pins, welded to the interior of the male adapter terminal; sockets, evenly distributed at the end of the female adapter terminal; a connector, riveted between the male adapter terminal and the female adapter terminal, which can restrict the relative movement between the male adapter terminal and the female adapter terminal; and a limiting member, movably disposed on the connector, which can restrict the relative movement between the connectors; wherein the LED lamp and the female adapter terminal are linearly connected, and the pins and sockets are in contact connection.

[0007] The technical effect of adopting the above-mentioned further solution is that the LED lamp adapter is electrically connected to the plug at the end of the adapter female terminal through the contact of the pin welded inside the adapter male terminal. The connector is riveted between the two to restrict relative movement, and the limiting member is movably set on the connector to restrict its relative movement. Moreover, the adapter female terminal is linearly connected to the LED lamp, which can stably realize the lamp power supply and ensure the connection stability.

[0008] In a preferred embodiment, the connector includes: an external thread evenly distributed on the outer surface of the male adapter; a positioning block movably disposed outside the female adapter, and having an internal thread inside; wherein the external thread and the internal thread engage with each other.

[0009] The technical advantages of adopting the above-mentioned further solution are as follows: the outer surface of the male adapter end is uniformly threaded with external threads, and the female adapter end is movably fitted with a positioning block with internal threads. The external threads and internal threads can cooperate with each other. When the positioning block is rotated, the engagement of the two threads can bring the male adapter end and the female adapter end closer together, achieving stable docking between the two, while limiting their lateral displacement, providing a solid structural foundation for subsequent conductive connection.

[0010] In a preferred embodiment, the connector further includes: a limiting block, welded to the outer surface of the adapter female end; and a positioning ring, welded to the lower end face of the internal thread; wherein the inner diameter of the positioning ring is the same as the diameter of the adapter female end.

[0011] The technical effect of adopting the above-mentioned further solution is that the positioning block is located outside the adapter female end, and the male and female ends are firmly connected by the threaded engagement. The limiting circle block and the positioning ring cooperate to accurately limit the movement range of the positioning block and the internal thread on the adapter female end, thereby enhancing the connection stability.

[0012] In a preferred embodiment, the limiting member includes: a first connecting block rotatably connected to the outside of the adapter male end; and a second connecting block welded to the outer surface of the positioning block.

[0013] The technical effect of adopting the above-mentioned further solution is that rotating the first connecting block can adjust its position so that it can cooperate with the second connecting block. Subsequently, through the synergistic effect of the two, the relative movement of the positioning block and the male adapter can be further restricted, which helps to enhance the stability of the connection between the male adapter and the female adapter and prevents the connection from becoming loose.

[0014] In a preferred embodiment, the limiting component further includes: a first limiting block, which is provided in multiple sets and welded to the lower end face of the first connecting block in a circular array; and a second limiting block, which is provided in multiple sets corresponding to the first limiting block and welded to the upper end face of the second connecting block; wherein the first limiting block and the second limiting block are engaged with each other.

[0015] The technical effect of adopting the above-mentioned further solution is that multiple sets of first limiting blocks of the limiting component are welded in a ring array to the lower end face of the first connecting block, and multiple sets of second limiting blocks are welded to the upper end face of the second connecting block corresponding to the first limiting blocks, and the two can engage with each other. After engagement, the relative rotation of the first connecting block and the second connecting block can be restricted, thereby constraining the movement of the positioning block and the male end of the adapter, avoiding loosening of the threaded fit, and enhancing the overall connection stability of the adapter.

[0016] In a preferred embodiment, the limiting member further includes: positioning holes, which are provided in multiple sets and are disposed through multiple sets of the first connecting block, the first limiting block, the second limiting block and the second connecting block; wherein the positions of the positioning holes on the first connecting block, the first limiting block, the second limiting block and the second connecting block correspond one-to-one.

[0017] The technical effect of adopting the above-mentioned further solution is that multiple sets of positioning holes penetrate the first connecting block, the first limiting block, the second limiting block, and the second connecting block, and the positions of the positioning holes on each component correspond one-to-one. This provides a precise channel for the subsequent insertion of locking components, allowing each limiting component to quickly align and form a stable connection, avoiding misalignment of the limiting structure, further ensuring the limiting effect, and strengthening the overall stability of the adapter connection.

[0018] In a preferred embodiment, the limiting member further includes a pin, which is movably mounted in the positioning hole; wherein the positioning hole and the pin are interference-fitted.

[0019] The technical effect of adopting the above-mentioned further solution is as follows: First, rotate the first connecting block so that the first limiting block and the second limiting block coincide. Then, insert the pin into the corresponding positioning hole. With the help of interference fit, the first and second connecting blocks are firmly locked, which effectively restricts the relative movement of the two, avoids loosening of the connection, and enhances the overall connection stability of the adapter.

[0020] In a preferred embodiment, the connector further includes an anti-slip pad, which is movably disposed between the male adapter and the female adapter; wherein the anti-slip pad is connected to the lower end face of the male adapter by adhesive bonding.

[0021] The technical effect of adopting the above-mentioned further solution is that the anti-slip pad is movably disposed between the male and female adapter terminals and is attached to the lower end face of the male adapter terminal by adhesive. It can fill the gap between the two terminals, increase the friction of the contact surface, avoid relative sliding caused by vibration, etc., and also improve the sealing performance of the connection, helping to maintain stable contact between the pin and the socket.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention provides comprehensive anti-loosening protection through multiple anti-loosening structures. First, the external thread on the outer surface of the male adapter precisely engages with the internal thread inside the positioning block, achieving initial thread fixation between the male and female adapters. Simultaneously, the limiting block on the outer surface of the female adapter and the positioning ring on the lower end face of the internal thread form an axial barrier, preventing excessive movement of the positioning block and thus increasing the thread clearance. Second, the first limiting block at the lower end of the first connecting block and the second limiting block at the upper end of the second connecting block engage accordingly, directly restricting the circumferential rotation of the positioning block and preventing the threads from loosening due to rotation. Finally, the interference fit between the pin and the positioning hole firmly locks the first connecting block, the first limiting block, the second limiting block, and the second connecting block into a single unit, further strengthening the dual constraints of circumferential and axial directions.

[0023] This multi-layered anti-loosening structure can effectively resist the effects of environmental factors such as long-term vibration and temperature changes. Even in scenarios where LED lights are frequently started and stopped or exposed to outdoor vibrations, it can still maintain the stability of the threaded connection, avoid poor contact between the pins and sockets due to loosening, and ensure the continuity of power supply to the LED lights.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please see Figures 1-5 This embodiment provides an adapter for LED lighting fixtures with high connection stability, and its specific concept is as follows: An adapter for LED lighting fixtures includes a male adapter terminal 1 and a female adapter terminal 2. The adapter for LED lighting fixtures also includes a pin 3, a socket 4, and a connector.

[0028] The male connector 1 has a pin 3 fixed inside by welding.

[0029] It should be noted that pin 3, as a key component for current conduction, lays the foundation for the subsequent conductive connection with adapter terminal 2.

[0030] In addition, the end of the adapter female terminal 2 is uniformly machined with insertion holes 4.

[0031] It should be noted that the position of the socket 4 corresponds precisely to the pin 3. When the male terminal 1 and the female terminal 2 of the adapter are assembled, the pin 3 can form a tight contact connection with the socket 4 to ensure stable current transmission.

[0032] Meanwhile, the LED lamps are connected to the adapter terminal 2 via a linear connection, enabling the lamps to obtain power through the adapter.

[0033] As examples, in this embodiment, the connector includes: an external thread 5, a positioning block 6, an internal thread 7, an anti-slip pad 10, a limiting block 16, and a positioning ring 15.

[0034] The outer surface of the male adapter 1 is uniformly provided with external threads 5.

[0035] In addition, a positioning block 6 is provided on the external movable sleeve of the adapter female end 2.

[0036] Meanwhile, the positioning block 6 has internal threads 7 machined inside.

[0037] It should be noted that the internal thread 7 and the external thread 5 have a perfect match in terms of tooth profile and pitch, which can achieve a threaded connection.

[0038] In addition, to limit the movement range of the positioning block 6 on the adapter female end 2, the outer surface of the adapter female end 2 is fixed with a limiting circular block 16 by welding.

[0039] Meanwhile, a positioning ring 15 is also welded to the lower end face of the internal thread 7 inside the positioning block 6.

[0040] In addition, the inner diameter of the positioning ring 15 is exactly the same as the diameter of the adapter female end 2.

[0041] It should be noted that when the positioning block 6 moves along the adapter end 2, the positioning ring 15 will form a blocking engagement with the limiting block 16 to prevent the positioning block 6 from falling off the adapter end 2.

[0042] In addition, an anti-slip pad 10 is movably provided between the mating surfaces of the male adapter 1 and the female adapter 2.

[0043] It should be noted that the anti-slip pad 10 is fixed to the lower end face of the male adapter 1 by adhesive.

[0044] It should be noted that when the male adapter 1 and the female adapter 2 are connected, the anti-slip pad 10 can fill the tiny gap between them and increase the friction of the contact surface.

[0045] In this embodiment, the male adapter 1 and the female adapter 2 are stably connected by the threaded connection of the external thread 5 and the internal thread 7, which avoids lateral displacement between the two during use. The cooperation between the limiting block 16 and the positioning ring 15 precisely limits the movement stroke of the positioning block 6, ensuring that the positioning block 6 is always in an effective position when the threaded connection is made. In addition, the anti-slip pad 10 not only enhances the sealing of the connection between the male adapter 1 and the female adapter 2, but also prevents the two from sliding relative to each other due to vibration and other factors, further improving the overall connection stability of the adapter. It also ensures stable contact between the pin 3 and the socket 4, avoiding poor conductivity due to loose connection.

[0046] Example 2: like Figures 1-5 As shown in Example 1, this example provides an adapter for LED lighting fixtures that achieves a more stable connection. The specific concept is as follows: The adapter for LED lighting also includes a limiting element.

[0047] As examples, in this embodiment, the limiting components include: a first connecting block 8, a second connecting block 9, a first limiting block 11, a second limiting block 12, a positioning hole 13, and a pin 14.

[0048] The adapter male end 1 is externally mounted with a first connecting block 8 via a rotatable connection.

[0049] It should be noted that the first connecting block 8 can rotate flexibly around the axis of the adapter male end 1.

[0050] In addition, the outer surface of the positioning block 6 is fixed with the second connecting block 9 by welding.

[0051] It should be noted that the second connecting block 9 moves synchronously with the positioning block 6, and its position corresponds vertically to that of the first connecting block 8.

[0052] Among them, multiple sets of first limiting blocks 11 are welded in a ring array on the lower end face of the first connecting block 8.

[0053] Correspondingly, multiple sets of second limiting blocks 12 are welded to the upper end face of the second connecting block 9.

[0054] It should be noted that the number and shape of the second limiting block 12 are completely matched with the first limiting block 11. When the first connecting block 8 is rotated to a specific angle, the first limiting block 11 can precisely engage with the second limiting block 12 to form a circumferential limit.

[0055] To further enhance the locking effect, multiple sets of positioning holes 13 are also provided through the first connecting block 8, the first limiting block 11, the second limiting block 12, and the second connecting block 9.

[0056] It should be noted that the diameter of each group of positioning holes 13 is consistent and their positions correspond one by one. When the first limiting block 11 and the second limiting block 12 are engaged, each group of positioning holes 13 can form a continuous channel.

[0057] In addition, the limiting component also includes a pin 14, the outer diameter of which is in an interference fit with the diameter of the positioning hole 13, and can be movably installed in the channel formed by the positioning hole 13 to achieve axial locking.

[0058] In this embodiment, the engagement of the first limiting block 11 and the second limiting block 12 effectively restricts the relative rotation between the first connecting block 8 and the second connecting block 9, thereby preventing the positioning block 6 from rotating due to vibration or other factors, and avoiding loosening of the external thread 5 and the internal thread 7. Furthermore, the interference fit between the positioning hole 13 and the pin 14 securely locks the first connecting block 8, the first limiting block 11, the second limiting block 12, and the second connecting block 9 into a single unit, further restricting the relative movement of each component in the axial direction, and completely eliminating the possibility of loosening between the male adapter end 1 and the female adapter end 2. The entire limiting structure is easy to operate; simply rotate the first connecting block 8 to engage the limiting block, and then insert the pin 14 to complete the locking. This ensures the reliability of the locking effect, facilitates subsequent disassembly and maintenance, and also maintains stable contact between the pin 3 and the socket 4 for a long time, ensuring the normal power supply of the LED lamp.

[0059] Working Principle: This device is an adapter for LED lighting fixtures. In use, first align the male adapter 1 with the female adapter 2, ensuring the pins 3 of the male adapter 1 are aligned with the sockets 4 of the female adapter 2. Slowly push the male adapter 1 to insert the pins 3 into the sockets 4, forming a contact connection. At this time, the anti-slip pad 10 is in contact with the male adapter 1 and the female adapter 2. Then, rotate the positioning block 6. The internal thread 7 of the positioning block 6 engages with the external thread 5 on the outer surface of the male adapter 1, causing the positioning block 6 to move upwards along the female adapter 2 until the positioning ring 15 contacts the limiting block 16, completing the initial fixation. At this point, the LED lighting fixture can obtain power through a linear connection with the female adapter 2.

[0060] Next, rotate the first connecting block 8 on the outside of the male adapter 1 so that the first limiting block 11 on its lower end face aligns and engages with the second limiting block 12 on the upper end face of the second connecting block 9 on the outer surface of the positioning block 6. Then check whether the positioning holes 13 on the first connecting block 8, the first limiting block 11, the second limiting block 12, and the second connecting block 9 are aligned. After confirming alignment, insert the pin 14 into the positioning hole 13. Because the positioning hole 13 and the pin 14 are interference-fitted, the pin 14 will be firmly fixed in the positioning hole 13, completing the assembly of the entire adapter. To disassemble, first pull out the pin 14, then rotate the first connecting block 8 in the opposite direction to separate the first limiting block 11 from the second limiting block 12. Then rotate the positioning block 6 in the opposite direction to disengage the internal thread 7 from the external thread 5. Finally, pull the male adapter 1 to separate it from the female adapter 2.
