Description

Technical Field

[0001] The utility model relates to the technical field of lighting lamps, and in particular to a bridge-free LED light strip plug. Background Art

[0002] The connection between the existing wireless light strip and the light strip plug (or connector) is generally achieved by plugging the positive and negative conductive terminals on the light strip into the positive and negative conductive terminals in the plug, thereby achieving electrical connection between the light strip and the light strip plug.

[0003] For example, the authorization announcement date is CN 212783942 U, and the patent name is a power connector for a light strip. The utility model integrates the original power supply housing (i.e., the first insulating housing) and the light strip fixing groove. By arranging a circuit board in the first insulating housing and a patch bridge stack on the circuit board, AC power is converted into DC power to adapt to the light strip power supply. Moreover, since the patch bridge stack is relatively small in size, the first insulating housing and the light strip fixing groove can be designed as an integrated structure. Only a section of power cord is needed to connect the light strip, which has the advantages of small consumables, simple structure, simple production process, low manufacturing cost and high production efficiency. At the same time, by designing a groove, a socket, a light strip fixing groove and a clamping cover on the first insulating housing, the second insulating housing of the light strip connector is connected to the groove, and the positive and negative conductors of the light strip connector are connected to the positive and negative conductive terminals in the socket. The clamping cover presses the light strip body onto the light strip fixing groove.

[0004] The connection method disclosed in the above patent is not stable enough between the light strip and the light strip plug, and is easily affected by external factors, such as the shaking of the light strip or the shaking of the light strip plug and the light strip when the light strip plug is plugged in. In this way, during the specific installation and use process, the positive and negative conductors of the light strip connector and the positive and negative conductive terminals in the socket are easily twisted and deformed, and the contact is easy to be poor, thereby affecting the electrical connection between the two and affecting the use of the entire power connector and the light strip.

[0005] Therefore, how to overcome the above-mentioned defects has become an important issue to be solved urgently by those skilled in the art. Utility Model Content

[0006] The utility model overcomes the shortcomings of the above-mentioned technology and provides a bridge-free LED light strip plug.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A bridge rectifier-free LED strip plug, comprising a strip connector, a power cord with one end extending into the strip connector, and a strip connected to the strip connector. A circuit board connected to the power cord is installed inside the strip connector. The strip connector includes a connection base for connecting the strip. A slot for inserting the strip is formed on the connection base. A cover body that can cover the upper end of the slot is snap-connected to the connection base through a snap connection structure. A plurality of first pressing members and second pressing members for pressing the strip in the slot are provided on the cover body. A third pressing member for pressing the strip in the slot is provided at the bottom of the slot.

[0009] Further, the snap connection structure includes snap blocks provided on the left and right side walls of the connection base, and card slots formed on the left and right side walls of the cover body for the snap blocks to be inserted into.

[0010] Further, the first pressing member includes protrusions provided on the inner wall of the upper end of the cover body. The protrusions extend downward to form a conical shape, and a plurality of the protrusions are arranged in a uniform manner.

[0011] Further, the second pressing member includes rectangular ribs provided on the inner wall of the upper end of the cover body. A plurality of the rectangular ribs are arranged in a uniform manner.

[0012] Further, the third pressing member includes arc-shaped portions provided on both sides of the slot.

[0013] Further, a limiting plate is provided on the inner wall of the upper end of the cover body. A limiting rib is provided at the front end of the limiting plate. A groove is formed between the limiting plate and the side wall of the cover body. There are two grooves, which are respectively located on the left and right sides of the limiting plate.

[0014] Further, a first positive and negative conductive terminal is provided at the other end of the circuit board, and a fuse tube is electrically connected to the circuit board.

[0015] Further, second positive and negative conductive terminals convenient for plugging with the first positive and negative conductive terminals are provided on the strip. A through hole is formed on the connection base. The first positive and negative conductive terminals are installed in the through hole. When the strip is inserted into the slot to be connected to the connection base, the second positive and negative conductive terminals are plugged onto the first positive and negative conductive terminals.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The lamp strip connector in this case includes a connecting base for connecting the lamp strip. A slot for inserting the lamp strip is provided on the connecting base, and a cover body that can cover the upper end of the slot is snap-connected to the connecting base through a snap connection structure.

The snap connection structure makes the installation process simple and fast, without the need for additional tools, improving the installation efficiency. A number of first pressing parts and second pressing parts for pressing the lamp strip in the slot are provided on the cover body, and a third pressing part for pressing the lamp strip in the slot is provided at the bottom of the slot.

[0021] The features of the present utility model and other related features are further described in detail through the following embodiments for the understanding of those skilled in the same industry:

[0022] Such as Figures 1 to 3As shown in the figure, this case discloses a bridge rectifier-free LED strip plug, which includes a strip connector 100, a power cord 1 with one end extending into the strip connector 100, and a strip 2 connected to the strip connector 100. In specific implementation, a power plug (not shown in the figure) is electrically connected to the other end of the power cord 1 for connecting to an external power source to supply power to the strip connector 100 and the strip 2. A circuit board 3 connected to the power cord 1 is installed inside the strip connector 100. In specific implementation, the power cord 1 is electrically connected to the circuit board 3 by welding to achieve electrical connection with the external power source. The strip connector 100 includes a connection base 4 for connecting the strip 2, and a slot 5 for the strip 2 to be inserted is provided on the connection base 4. In specific implementation, the upper end of the slot 5 is open to facilitate accommodating the strip 2 in the slot 5. The width and depth of the slot 5 should match the size of the strip 2 to ensure that the strip 2 can be inserted smoothly and remain stable. A cover 6 that can cover the upper end of the slot 5 is snap-fitted on the connection base 4. While the cover 6 realizes snap-fitting with the connection base 4 through the snap-fitting structure, it can cover the slot 5 to protect the connection between the strip 2 and the connection base 4, and at the same time press the strip 2 tightly in the slot. The snap-fitting structure makes the installation process simple and fast, without the need for additional tools, improving the installation efficiency. A number of first pressing members and second pressing members for pressing the strip 2 in the slot 5 are provided on the cover 6, and a third pressing member for pressing the strip 2 in the slot 5 is provided at the bottom of the slot 5. Through the combined design of the first pressing member, the second pressing member and the third pressing member, the strip 2 is pressed tightly in the slot 5 by the cover 6, effectively ensuring the close contact between the strip 2 and the connection base 4, improving the stability of their connection, reducing the maintenance and replacement times due to poor contact, and reducing the maintenance cost.

[0023] Specifically, as Figures 1 - 3 shown in the figure, the snap-fitting structure of this case includes snap blocks 41 provided on the left and right side walls of the connection base 4, and slots 61 provided on the left and right side walls of the cover 6 for the snap blocks 41 to be snapped into. In specific implementation, one, two or more than two snap blocks 41 can be provided, and the number of slots 61 can be set according to the number of snap blocks 41. To make the snap-fitting between the cover 6 and the connection base 4 more stable and convenient for disassembly, preferably, two snap blocks 41 and two slots 61 are respectively provided in this case. The cover 6 is usually made of an insulating and flexible material, such as polycarbonate, etc., to ensure electrical safety and at the same time facilitate the snap-fitting between the cover 6 and the connection base 4 through the flexibility of the cover 6.

[0024] Specifically, Figure 3As shown, the first pressing member of this case includes a protrusion 62 provided on the inner wall of the upper end of the cover 6, and the protrusion 62 extends downward to form a cone. That is to say, the protrusion 61 is provided inside the cover 6 and has a conical or similar conical structure, with a relatively pointed top and a relatively wide bottom. After the light strip 2 is installed, the protrusion 62 is usually perpendicular to the contact surface of the light strip 2. When the cover 6 is pressed downward and snapped onto the connecting seat 4, the light strip 2 can be pressed into the slot 5, making the connection between the light strip 2 and the connecting seat 4 more stable, effectively avoiding the problem of poor contact between the two due to vibration or movement of the light strip 2 or the light strip connector 100. A number of protrusions 62 are arranged evenly. Specifically, the number of protrusions 62 can be set according to the size of the light strip 2 to ensure that the cover 6 can apply sufficient contact pressure to the light strip 2 and increase the friction between the two.

[0025] Specifically, Figure 3 As shown, the second pressing member includes rectangular ribs 63 provided on the inner wall of the upper end of the cover 6, and a number of rectangular ribs 63 are arranged evenly. The rectangular ribs 63 are used to further strengthen the contact pressure between the light strip 2 and the connecting seat 4 and ensure the stability of their connection. Its function is similar to that of the above-mentioned protrusion 62. Different from the effect of the protrusion 62 described above, when the rectangular rib 63 presses the light strip 2, it is not easy to damage the light strip 2. However, if only the rectangular rib 63 is provided, the friction between the light strip 2 and the cover 6 may not be enough. Therefore, in specific implementation, the protrusion 62 and the rectangular rib 63 are arranged in cooperation. And to make the connection between the front end of the light strip 2 and the connecting seat 4 stable and not affect the electrical connection between the light strip 2 and the internal circuit board 3 of the light strip connector 100, the protrusion 62 is provided at the front end of the rectangular rib 63.

[0026] Specifically, as Figures 1 - 2 As shown, the third pressing member includes arc-shaped portions 51 provided on both sides of the slot 5. Specifically, the arc-shaped portions 51 are located on both sides of the bottom of the slot 5. The arc-shaped portions 51 play a guiding role and help guide the light strip 2 into the slot 5. When the light strip 2 is inserted into the slot 5, it can ensure that the light strip 2 is correctly placed in the slot 5, avoiding misalignment or distortion of the light strip 2. At the same time, the stability of the connection between the light strip 2 and the connecting seat 4 is enhanced. The radian of the arc-shaped portion 51 can be appropriately adjusted according to the thickness of the light strip 2 to ensure a good contact effect.

[0027] Furthermore, as Figure 3As shown in the figure, a limiting plate 64 is further provided on the inner wall at the upper end of the cover body 6. A limiting rib 641 is provided at the front end of the limiting plate 64. A groove 65 is formed between the limiting plate 64 and the side wall of the cover body 6. There are two grooves 65, which are respectively located on the left side and the right side of the limiting plate 64. The limiting plate 64 and the cover body 6 are integrally formed for convenient production. It should be noted that when the limiting plate 64 is provided, the protrusion 62 and the rectangular rib 63 are both provided on the limiting plate 64. When the cover body 6 is clamped on the connecting seat 4, the left and right side walls of the connecting seat 4 are respectively clamped into the corresponding grooves 65 on the corresponding side, and the limiting rib 641 falls into the slot 5 between the left and right side walls of the connecting seat 4. In this way, the setting of the limiting plate 64 further strengthens the stability of the connection between the cover body 6 and the connecting seat 4.

[0028] Further, as Figure 3 shown, the other end of the circuit board 3 is provided with a first positive and negative conductive terminal 31 for facilitating electrical connection with the LED strip 2. A fuse tube 32 is electrically connected to the circuit board 3, which can effectively perform over-current protection.

[0029] Further, as Figure 3 shown, the LED strip 2 is provided with a second positive and negative conductive terminal 21 for facilitating insertion into the first positive and negative conductive terminal 31. A through hole 42 is formed in the connecting seat 4, and the first positive and negative conductive terminal 31 is installed in the through hole 42. The setting of the through hole 42 is beneficial to installing the first positive and negative conductive terminal 31 in the through hole 42, ensuring that the first positive and negative conductive terminal 31 will not be easily displaced, so as to improve the stability of the connection. When the LED strip 2 is inserted into the slot 5 to be connected to the connecting seat 4, the second positive and negative conductive terminal 21 is inserted onto the first positive and negative conductive terminal 31. Through this structure, the electrical connection between the two is convenient and fast. In specific implementation, the first positive and negative conductive terminal 31 and the second positive and negative conductive terminal 21 are usually made of materials with good electrical conductivity, such as copper or silver-plated copper. The shapes of the first positive and negative conductive terminal 31 and the second positive and negative conductive terminal 21 are designed as structures that are easy to be inserted and matched, such as pin type, blade type, etc.

[0030] As described above, the present case protects a bridge-less LED strip plug. All technical solutions identical or similar to the present case should be regarded as falling within the protection scope of the present case.
