Description

Technical Field

[0001] This invention relates to the field of lighting fixtures and appliances, and in particular to a waterproof device for LED strip lights. Background Technology

[0002] Currently, with the development of urban economies and the improvement of people's living standards, urban cultural construction is receiving increasing attention. Neon lights and other light strips are an important component of urban nightscape design. Generally, these light strips are installed outdoors, and multiple strips are typically strung together to form a longer strip to meet the design requirements of the urban nightscape. This necessitates that the light strips have a certain degree of waterproofing, especially at the connection points between adjacent strips, to prevent water from entering and affecting the normal operation of the light strip or even causing a short circuit. Existing waterproofing devices for connecting light strips vary in structure. Some use bolts to tighten two adjacent light strips and press them against a sealing element to achieve a seal, but the installation and disassembly of existing waterproofing devices are inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a waterproof LED strip device that is easy to install and remove.

[0004] To achieve the above objectives, the present invention provides a waterproof device for LED strips, used to seal two adjacent LED strips, comprising: a first connector, a second connector, a sealing plate, and a cover;

[0005] The first connector is used for fixed connection with one of the light strips; the first connector has a first limiting pin;

[0006] The second connector is used for fixed connection with another of the light strips; the second connector has a second limiting pin;

[0007] A sealing plate, wherein the opposite two end faces of the sealing plate are respectively used to be fitted one-to-one with the connecting surfaces of two adjacent light strips;

[0008] The cover has a first slot and a second slot spaced apart along a predetermined direction; the first limiting pin and the second limiting pin are respectively pluggable and snapped into the first slot and the second slot;

[0009] The opening edge of the first bayonet has an inclined section; when the first limiting pin passes through the inclined section, the first limiting pin moves along the predetermined direction, the first connecting member and the second connecting member approach each other, and the sealing plate abuts against the connecting surface to form a seal.

[0010] Compared with the prior art, the waterproof LED strip device of this invention has the following advantages: By fixing the first and second connecting members to two adjacent LED strips respectively, the first connecting member and the second connecting member are connected together through the first and second latches of the cover, and the sealing plate is clamped and adhered to the connecting surface of the two adjacent LED strips. Because the opening edge of the first latch has an inclined section, during the process of the cover closing onto the first and second connecting members, and during the process of the first limiting pin engaging the first latch, the first limiting pin moves along a predetermined direction when passing the inclined section, thereby causing the first and second connecting members to move closer to each other, and thus causing the two adjacent LED strips to move towards each other and press against the sealing plate, achieving a seal between the two adjacent LED strips.

[0011] When separating two adjacent light strips as needed, simply move the cover in the opposite direction. The first limiting pin and the first limiting pin slide out from the first bayonet and the second bayonet respectively, which will separate the first connector from the second connector, release the seal of the first connector on the light strip, and realize the separation of the two light strips. This waterproof device has a simple structure and is easy to disassemble and install.

[0012] Furthermore, it also includes a connecting piece for electrical connection with the LED strip; the sealing plate has a through hole for the connecting piece to pass through, and the sealing surfaces of the sealing plate are distributed around the through hole. This design effectively prevents the connecting piece from coming into contact with water, thus preventing a short circuit, and also avoids the possibility of water entering the LED strip through the through hole. This improves the waterproof performance of the device. The sealing surface is the contact surface between the LED strip and the sealing plate.

[0013] Specifically, the terminal is located on the connecting surface of the light strip. The terminal of the light strip is a notch. After the connecting piece is inserted into the notch, the connecting piece is connected to the light strip circuit. At this time, the sealing plate fits perfectly against the connecting surface.

[0014] Furthermore, it also includes a fixing plate for fixedly connecting to the light strip; the fixing plate is detachably connected to the second connector. The second connector is fixedly connected to the light strip via the fixing plate, and the detachable connection between the fixing plate and the second connector facilitates the replacement and removal of the second connector.

[0015] Specifically, the fixing plate is fixed with multiple protrusions, each with a pointed tip. These protrusions are used to insert into the rubber shell of the light strip, thereby achieving a fixed connection between the fixing plate and the light strip. This connection method is simple and the connection is firm and reliable.

[0016] Specifically, the fixing plate is provided with a snap-fit ​​piece, and the second connector has a snap-fit ​​groove. The snap-fit ​​piece can be inserted and snapped into the snap-fit ​​groove. The extension direction of the snap-fit ​​groove is perpendicular to the predetermined direction, which can prevent the snap-fit ​​piece from moving along the predetermined direction with the fixing plate, thus ensuring the contact pressure between the first connector and the sealing plate and improving the waterproof capability of the light strip.

[0017] Furthermore, the first connector and the second connector have the same structure; there are two fixing plates, and each fixing plate is detachably connected to the first connector and the second connector respectively; the two fixing plates are used to fix two adjacent light strips respectively. The fact that the first connector and the second connector have the same structure facilitates the connection of two adjacent light strips, and also makes the parts simpler, which is convenient for production and processing.

[0018] Furthermore, it also includes a connecting plate located between the first connecting member and the second connecting member, and the connecting plate has an assembly hole for the connecting piece to pass through; both ends of the connecting plate are sealed with sealing plates, and the two sealing plates are respectively used to seal and fit with two adjacent light strips (specifically, the two adjacent connecting surfaces are respectively sealed and connected with the two sealing plates). By setting the connecting plate, the sealing plates can fit better against the connecting plate, and when the first connecting member and the second connecting member move towards each other and squeeze the sealing plate, the sealing plate can be guaranteed to have a certain resistance to deformation, reducing the impact of the deformation of the sealing plate on the connecting piece.

[0019] Specifically, the connecting plate is equipped with a pressure plate, which is located above the connecting piece. When the connecting piece is inserted into the recess, the pressure plate is also inserted into the recess. The pressure plate presses the connecting piece onto the wiring port inside the recess, ensuring that the connecting piece and the wiring port maintain good contact at all times.

[0020] Furthermore, the first limiting pin has an inclined surface that mates with the inclined section. The inclined surface facilitates better engagement between the first limiting pin and the inclined section, promoting the movement of the first limiting pin and reducing wear on the inclined surface from the inclined section.

[0021] Furthermore, the shape of the second latch is symmetrical to the shape of the first latch; the shape of the first limiting pin is symmetrical to the shape of the second limiting pin. This design allows the first and second limiting pins to move towards each other when the cover is closed, compressing the sealing plate and improving the sealing effect.

[0022] Specifically, the axes of symmetry of the first and second bayonets are perpendicular to a predetermined direction, and the axes of symmetry of the first and second limiting pins are perpendicular to a predetermined direction.

[0023] Furthermore, there are two of each of the first latch, the second latch, the first limiting pin, and the second limiting pin; the two first latches, the two second latches, the two first limiting pins, and the two second limiting pins are respectively distributed on both sides of the predetermined direction. This arrangement can reasonably distribute the pressure of the first connecting member on the second connecting member, so that the force on the sealing plate is also reasonably even.

[0024] Furthermore, it also includes a bottom shell, which has a groove for accommodating the first connector and the second connector; the groove is slidably connected to the first connector and the second connector; the groove provides a snap-fit ​​connection between the bottom shell and the cover. When the light strip is subjected to other external forces intersecting the predetermined direction, relative rotation occurs between the light strip and the first connector, leading to a reduction or even failure of the sealing capability; the bottom shell is used to restrict the first connector and the second connector to move only in the predetermined direction, thereby ensuring normal sealing between the light strip and the sealing plate.

[0025] Furthermore, the chute is provided with a slot for the connecting plate to be inserted; the connecting plate is perpendicular to the predetermined direction. The connecting plate, when inserted into the slot, remains stationary and does not rotate relative to the predetermined direction even under the compressive force of two adjacent light strips, thus ensuring stable compressive force between the sealing plate and the light strips and guaranteeing a sealing effect.

[0026] Specifically, the bottom shell is fixedly provided with a locking pin that cooperates with the locking hole. The locking pin and the locking hole realize the snap connection between the cover and the bottom shell, restrict the movement of the bottom shell relative to the first connector and the second connector, and improve the firmness of the connection between the two light strips.

Detailed Implementation

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0034] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides a waterproof device for LED strips, used to seal two adjacent LED strips 5, comprising: a first connector 1, a second connector 2, a sealing plate 3, and a cover 4.

[0035] The first connector 1 is used to fix a light strip 5 to a light strip; the first connector 1 has a first limiting pin 11;

[0036] The second connector 2 is used for fixed connection with another light strip 5; the second connector 2 has a second limiting pin 21;

[0037] The sealing plate 3 has two opposite end faces that are respectively used to be attached to the connecting surfaces 51 of two adjacent light strips 5.

[0038] The cover 4 has a first slot 41 and a second slot 42 that are spaced apart along a predetermined direction; the first limiting pin 11 and the second limiting pin 21 are respectively pluggable and snapped into the first slot 41 and the second slot 42.

[0039] The opening 93 of the first bayonet 41 has an inclined section 43 at its edge; when the first limiting pin 11 passes through the inclined section 43, the first limiting pin 11 moves in a predetermined direction, the first connecting member 1 and the second connecting member 2 approach each other, and the sealing plate 3 abuts against the connecting surface 51 to form a seal.

[0040] Compared with the prior art, the waterproof LED strip device of this invention has the following advantages: by fixing the first connector 1 and the second connector 2 to two adjacent LED strips 5 respectively, the first connector 1 and the second connector 2 are connected together by the first latch 41 and the second latch 42 of the cover body 4, and the sealing plate 3 is clamped and attached to the connecting surface 51 of the two adjacent LED strips 5. Since the opening 93 of the first latch 41 is provided with an inclined section 43, during the process of the cover body 4 covering the first connector 1 and the second connector 2, and during the process of the first limiting pin 11 being inserted into the first latch 41, when the first limiting pin 11 passes through the inclined section 43, the first limiting pin 11 will move in a predetermined direction, thereby causing the first connector 1 and the second connector 2 to move closer to each other, thereby causing the two adjacent LED strips 5 to move towards each other and squeeze the sealing plate 3, thus achieving the sealing of the two adjacent LED strips 5.

[0041] When two adjacent light strips 5 need to be separated, the cover 4 can be moved in the opposite direction. The first limiting pin 11 and the first limiting pin 2 slide out from the first bayonet 41 and the second bayonet 42 respectively, which can separate the first connecting piece 1 from the second connecting piece 2, release the seal of the first connecting piece 1 on the light strip 5, and realize the separation of the two light strips 5. The waterproof device has a simple structure and is easy to disassemble and install.

[0042] In one embodiment, a connecting piece 6 for electrical connection with the light strip 5 is also included; a through hole 31 is provided on the sealing plate 3 for the connecting piece 6 to pass through, and sealing surfaces on the sealing plate 3 are distributed around the through hole 31. This arrangement effectively prevents the connecting piece 6 from contacting water, thus preventing a short circuit, and also avoids the possibility of water entering the light strip 5 through the through hole 31. This improves the waterproof performance of the device. The sealing surface is the contact surface between the light strip 5 and the sealing plate 3.

[0043] Specifically, terminal 52 is located on the connecting surface 51 of the light strip 5. Terminal 52 of the light strip 5 is a notch. After the connecting piece 6 is inserted into the notch, the connecting piece 6 is connected to the circuit of the light strip 5. At this time, the sealing plate 3 fits perfectly on the connecting surface 51.

[0044] In one embodiment, a fixing plate 7 is further included for fixedly connecting to the light strip 5; the fixing plate 7 is detachably connected to the second connector 2. The second connector 2 is fixedly connected to the light strip 5 via the fixing plate 7, and the detachable connection between the fixing plate 7 and the second connector 2 facilitates the replacement and removal of the second connector 2.

[0045] Specifically, such as Figure 4 As shown, a plurality of protrusions 71 are fixedly provided on the fixing plate 7, and the protrusions 71 have pointed ends. The protrusions 71 are used to insert into the rubber shell of the light strip 5 to achieve a fixed connection between the fixing plate 7 and the light strip 5. This connection method is simple and the connection is firm and reliable.

[0046] Specifically, such as Figure 4 As shown, the fixing plate 7 is provided with a snap-fit ​​piece 72, and the second connector 2 is provided with a snap-fit ​​groove 22. The snap-fit ​​piece 72 can be inserted and snapped into the snap-fit ​​groove 22. The extension direction of the snap-fit ​​groove 22 is perpendicular to the predetermined direction, which can prevent the snap-fit ​​piece 72 from moving along the predetermined direction with the fixing plate 7, thus ensuring the contact pressure between the first connector 1 and the sealing plate 3 and improving the waterproof capability of the light strip 5.

[0047] In one embodiment, the first connector 1 and the second connector 2 have the same structure; there are two fixing plates 7, and the two fixing plates 7 are detachably connected to the first connector 1 and the second connector 2 respectively; the two fixing plates 7 are respectively used to fix two adjacent light strips 5 one-to-one. The fact that the first connector 1 and the second connector 2 have the same structure facilitates the connection of two adjacent light strips 5, and also makes the parts simpler, which is convenient for production and processing.

[0048] In one embodiment, such as Figure 2 and Figure 3 As shown, it also includes a connecting plate 8 located between the first connecting member 1 and the second connecting member 2, and the connecting plate 8 has an assembly hole 81 for the connecting piece 6 to pass through; sealing plates 3 are sealed and attached to both ends of the connecting plate 8, and the two sealing plates 3 are respectively used to seal and attach to two adjacent light strips 5 in a one-to-one correspondence (specifically, the two adjacent connecting surfaces 51 are respectively sealed and connected to the two sealing plates 3 in a one-to-one correspondence). By setting the connecting plate 8, the sealing plates 3 can fit better against the connecting plate 8, and when the first connecting member 1 and the second connecting member 2 move towards each other and squeeze the sealing plates 3, it can ensure that the sealing plates 3 have a certain resistance to deformation and reduce the impact of the deformation of the sealing plates 3 on the connecting piece 6.

[0049] Specifically, the connecting plate 8 is provided with a pressure plate 82, and the pressure plate 82 is located above the connecting piece 6. When the connecting piece 6 is inserted into the recess, the pressure plate 82 is also inserted into the recess. The pressure plate 82 presses the connecting piece 6 onto the wiring port in the recess, ensuring that the connecting piece 6 and the wiring port always maintain good contact.

[0050] like Figure 2 and 3 As shown, the second connector 2 has a groove for accommodating the first connector 1 and the fixing plate 7, and the first connector 1 is slidably connected to the groove. The groove extends in a predetermined direction, effectively restricting the first connector 1 to move only in the predetermined direction and pressing against the connecting surface 51 of the light strip 5. This ensures a normal seal between the light strip 5 and the sealing plate 3. In one embodiment, the first limiting pin 11 has a slope 12 that cooperates with the inclined section 43. The slope 12 facilitates better cooperation between the first limiting pin 11 and the inclined section 43, promotes the movement of the first limiting pin 11, and also reduces wear on the slope 12 caused by the inclined section 43.

[0051] In one embodiment, the shape of the second latch 42 is symmetrical to the shape of the first latch 41; the shape of the first limiting pin 11 is symmetrical to the shape of the second limiting pin 21. This design allows the first limiting pin 11 and the second limiting pin 21 to move towards each other when the cover 4 is closed, and to press the sealing plate 3, thereby improving the sealing effect.

[0052] Specifically, the axis of symmetry of the first bayonet 41 and the second bayonet 42 is perpendicular to the predetermined direction, and the axis of symmetry of the first limiting pin 11 and the second limiting pin 21 is perpendicular to the predetermined direction.

[0053] In one embodiment, such as Figure 2 and 3 As shown, there are two of each of the following: the first latch 41, the second latch 42, the first limiting pin 11, and the second limiting pin 21. The two first latches 41, the two second latches 42, the two first limiting pins 11, and the two second limiting pins 21 are distributed one-to-one on both sides of a predetermined direction. This arrangement can reasonably distribute the pressure of the first connecting member 1 on the second connecting member 2, resulting in a reasonable and even force distribution on the sealing plate 3.

[0054] In one embodiment, the cover 4 and the second connector 2 are snap-fitted together. This snap-fit ​​connection allows the cover 4 and the second connector 2 to be connected, facilitating subsequent installation and disassembly.

[0055] In one embodiment, such as Figure 2 and 3 As shown, it also includes a bottom shell 9, which has a groove 91 for accommodating the first connector 1 and the second connector 2; the groove 91 is slidably connected to the first connector 1 and the second connector 2; the groove 91 has a snap-fit ​​connection between the bottom shell 9 and the cover 4. When the light strip 5 is subjected to other external forces intersecting the predetermined direction, the light strip 5 and the first connector 1 will rotate relative to each other, resulting in a reduction or even failure of the sealing ability; the bottom shell 9 is used to restrict the first connector 1 and the second connector 2 to move only in the predetermined direction, thereby ensuring the normal sealing between the light strip 5 and the sealing plate 3.

[0056] In one embodiment, such as Figure 2 and 3 As shown, the slide groove 91 is provided with a slot 94 for the connecting plate 8 to be inserted; the connecting plate 8 is perpendicular to the predetermined direction. The connecting plate 8 inserted into the slot 94 can still remain stationary or rotate relative to the predetermined direction under the squeezing force of two adjacent light strips 5, thereby ensuring the stability of the squeezing force between the sealing plate 3 and the light strip 5 and ensuring the sealing effect.

[0057] Specifically, a locking pin 92 that cooperates with the locking hole 44 is fixed on the bottom shell 9. The locking pin 92 and the locking hole 44 realize the snap connection between the cover 4 and the bottom shell 9, restrict the movement of the bottom shell 9 relative to the first connecting member 1 and the second connecting member 2, and improve the firmness of the connection between the two light strips 5.

[0058] like Figure 2 and 3 As shown, the bottom shell 9 has two openings 93 for the first limiting pin 11 and the second limiting pin 21 to be inserted. This is mainly to ensure that the first limiting pin 11 and the second limiting pin 21 can pass through the bottom shell 9 and protrude when the cover 4 and the bottom shell 9 are connected by a snap fastener, so that they can be inserted into the corresponding first snap slot 41 and second snap slot 42.

[0059] Specifically, sealing plate 3 is made of silicone sheet, which effectively improves sealing performance.

[0060] In summary, this invention provides a waterproof LED strip device, which fixes the first connector 1 and the second connector 2 to two adjacent LED strips 5 respectively. The first connector 1 and the second connector 2 are connected together by the first latch 41 and the second latch 42 of the cover body 4, and the sealing plate 3 is clamped and attached to the connecting surface 51 of the two adjacent LED strips 5. Since the opening 93 of the first latch 41 has an inclined section 43 at its edge, during the process of the cover body 4 closing onto the first connector 1 and the second connector 2, and during the process of the first limiting pin 11 being engaged with the first latch 41, when the first limiting pin 11 passes through the inclined section 43, the first limiting pin 11 will move in a predetermined direction, thereby causing the first connector 1 and the second connector 2 to move closer to each other, thereby causing the two adjacent LED strips 5 to move towards each other and squeeze the sealing plate 3, thus achieving a seal between the two adjacent LED strips 5.

[0061] When two adjacent light strips 5 need to be separated, the cover 4 can be moved in the opposite direction. The first limiting pin 11 and the first limiting pin 2 slide out from the first bayonet 41 and the second bayonet 42 respectively, which can separate the first connecting piece 1 from the second connecting piece 2, release the seal of the first connecting piece 1 on the light strip 5, and realize the separation of the two light strips 5. The waterproof device has a simple structure and is easy to disassemble and install.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
