Description

Technical Field

[0001] This invention relates to the field of lamp holder clamp technology, specifically to a lamp holder clamp. Background Technology

[0002] LED lights are common lighting devices. Common LED lights and other lighting devices consist of a light-emitting device, a circuit board, and a housing, which are assembled into finished lighting devices.

[0003] During the assembly process, the assembly order is extremely important. Since most light-emitting devices are tube-shaped and their circuit connection wires are wrapped in conduits, it is necessary to insert the wires through the outer casing before connecting the circuit.

[0004] In actual assembly, because the outer shell and inner lining fasteners have through holes to accommodate the wires, it is necessary to ensure that the dimensions of the through holes and wires meet the requirements. One end of the light-emitting device is connected to the circuit board, so the size of this end must be larger than the inner diameter of the through hole. Therefore, the other end must be smaller than the inner diameter of the through hole when it is inserted, which limits the size of the light-emitting device. Moreover, the existing common connection method is mostly a threaded rotation connection. Therefore, when the circuit board is fixedly connected to the inner lining block, the screw at the connection position between the circuit board and the cable will rotate during the threaded rotation installation, which will affect the connection stability of the circuit and easily cause the connection to fall off. Summary of the Invention

A perforation component is provided through the middle of the inner liner block and the fixing block to facilitate the installation of the electrical conduit. An opening slot communicating laterally with the perforation component is provided on one side of both the inner liner block and the fixing block. A first locking block is provided at one end of the circuit board near the fixing block, and a locking groove is provided on the fixing block for insertion and fixing with the first locking block. The circuit board and the contact connector are electrically connected by a folded cable. A spring is elastically pressed between the circuit board and the inner wall of the connector cover.

[0008] Preferably, the lampshade is threadedly rotatably mounted on one end of the connector cover, the light-emitting tube extends into the inner cavity of the lampshade, and a connecting post is fixed to the other end of the connector cover. One end of the connecting post is connected to a contactor, and the other end of the connecting post is connected to a cable.

[0009] Preferably, the pore assembly includes a first through hole penetrating the inner liner block and a second through hole penetrating the fixing block, and the opening groove includes a first opening provided on the inner liner block and a second opening provided on the fixing block.

The first card block is inserted and installed along the card slot, and the front and rear side walls of the first card block are provided with pressing grooves that are inserted into the protrusions, and the pressing grooves correspond one-to-one with the protrusions.

[0012] Preferably, a second locking block is symmetrically arranged on the side of the circuit board away from the first locking block. The circuit board is provided with multiple sets of through holes. The first locking block and the second locking block are provided with mounting holes corresponding to the through holes. A pin made of insulating material is inserted through the mounting holes and the through holes.

[0013] Preferably, the end of the cable is provided with a connector plate, the connector plate is provided with a plug, and the circuit board is provided with a terminal block that is fixedly connected to the plug on the side near the cable.

[0014] Preferably, multiple sets of telescopic columns are provided on the inner wall of the end of the connector cover, and the other end of the telescopic column is fixed to the connector plate, with a spring pressing between the connector plate and the outer wall of the middle section of the telescopic column.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention removes the limitation on the size of the stacked light-emitting tube by opening an opening on one side that communicates with the through hole. As long as the size of the tube in the connecting section is compatible with the size of the opening and the through hole, the lateral installation of the light-emitting device can be achieved. The position of the pluggable inner liner block and the fixing block is limited, and then the opening is misaligned by the screw rotation, so that it will not fall off laterally after installation.

[0019] By setting an elastic connection between the circuit board and the contact connector, the circuit board is prevented from rotating with the threaded assembly during the assembly process. After assembly, the spring's return force and the traction on the light-emitting device are used to ensure that it is snapped and fixed, thus achieving the stability of the connection after assembly.

[0028] 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, and 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.

[0029] Please see Figures 1 to 7 The present invention provides a technical solution:

[0030] Example 1: A lamp holder clamp, comprising a lampshade 1, a light-emitting component and a connector cover 3. The light-emitting component includes a light-emitting tube 6 for emitting light and illumination, a circuit board 2 for controlling the light-emitting tube 6 and an electrical conduit 5 for connecting wires. An external power contact 4 is provided on the outside of the connector cover 3.

[0031] The circuit board 2 is powered by an external power source connected to the contact connector 4, which in turn causes the light-emitting tube 6 to emit light, thus achieving the purpose of illumination. The circuit board 2 and the light-emitting tube 6 are electrically connected by the tube 5.

[0032] The connector cover 3 has an inner liner block 7 inside, and a detachable fixing block 8 is provided in the inner liner block 7. A hole component is provided through the middle of the inner liner block 7 and the fixing block 8 to facilitate the installation of the electric conduit 5. An opening slot that communicates laterally with the hole component is provided on one side of both the inner liner block 7 and the fixing block 8. A first locking block 14 is provided at one end of the circuit board 2 near the fixing block 8. A locking groove 22 is provided on the fixing block 8 to be inserted and fixed with the first locking block 14. The circuit board 2 and the contact connector 4 are electrically connected by a folded cable 11. A spring 10 is elastically pressed between the circuit board 2 and the inner wall of the connector cover 3.

[0033] By setting an opening slot, the electrical conduit 5 is laterally installed on the inner liner block 7 and the fixing block 8, thereby allowing the electrical conduit 5 to be installed on the perforated assembly. The electrical conduit 5 passes through the inner liner block 7 and the fixing block 8. The spring 10 is used to elastically compress the circuit board 2 during the installation process of the inner liner block 7 and the fixing block 8, so that its position will not affect the installation of the inner liner block 7 and the fixing block 8. The return force of the spring 10 and the traction on the electrical conduit 5 are used to make the first locking block 14 lock into the locking slot 22, achieving the purpose of fixed assembly and installation, and ensuring the stability of the circuit connection.

[0034] Working principle: First, the conduit 5 is laterally installed on the inner liner block 7 and the fixing block 8 through the opening slot. Then, the circuit board 2 is connected to the cable 11, and the spring 10 is squeezed to move the circuit board 2 into the inner cavity of the connector cover 3. This ensures that the installation position of the circuit board 2 does not affect the installation of the inner liner block 7 and the fixing block 8. At this time, the circuit board 2 is not fixed to the inner liner block 7 and the fixing block 8. Therefore, the threaded rotation of the inner liner block 7 and the fixing block 8 affects the rotation of the circuit board 2 and the conduit 5, ensuring the stability of the connection. After the inner liner block 7 and the fixing block 8 are installed, the return force of the spring 10 and the traction on the conduit 5 are used to make the first locking block 14 engage in the locking slot 22, achieving the purpose of fixed assembly and installation, and ensuring the stability of the circuit connection.

[0035] Example 2: Based on Example 1, the lampshade 1 is screwed and rotated on one end of the connector cover 3, the light-emitting tube 6 extends into the inner cavity of the lampshade 1, and the other end of the connector cover 3 is fixed with a connecting post 13. One end of the connecting post 13 is connected to the contact connector 4, and the other end of the connecting post 13 is connected to the cable 11.

[0036] By setting the connecting post 13, the cable 11 is connected to the contact connector 4, so that power can be supplied to the circuit board 2 after the external power supply is connected.

[0037] The porous component includes a first through hole 21 penetrating the inner liner block 7 and a second through hole 26 penetrating the fixing block 8. The opening groove includes a first opening 20 provided on the inner liner block 7 and a second opening 29 provided on the fixing block 8. The width of the first opening 20 and the second opening 29 is equal to the inner diameter of the first through hole 21 and the second through hole 26. The outer diameter of the electric conduit 5 is smaller than the inner diameter of the first through hole 21 and the second through hole 26.

[0038] Lateral installation of the electrical conduit 5 is achieved by setting an opening slot and a perforation assembly.

[0039] The inner cavity port of the connector cover 3 is provided with a second internal thread 31, the outer wall of the inner liner block 7 is provided with a first external thread 24 that mates with the second internal thread 31, one side of the inner liner block 7 is provided with a first internal thread 19, and the outer side of the fixing block 8 is provided with a second external thread 25 that mates with the first internal thread 19.

[0040] By setting internal and external threads, the fixing block 8 is fixedly installed on the inner liner block 7, and the inner liner block 7 is fixedly installed in the inner cavity of the connector cover 3. At the same time, by using the thread rotation fit, after the inner liner block 7 and the fixing block 8 are fixedly installed, the first opening 20 and the second opening 29 are mutually misaligned, thereby achieving the purpose of sealing the second opening 29 and preventing the electrical conduit 5 from falling off laterally.

[0041] Example 3: Based on Example 2, the card slot 22 is configured as multiple sets distributed in a circumferential array, and the inner wall of the card slot 22 is provided with multiple sets of protrusions 23 distributed at intervals. The first card block 14 is inserted and installed along the card slot 22, and the front and rear side walls of the first card block 14 are provided with pressing grooves 16 that are inserted into the protrusions 23 respectively. The pressing grooves 16 correspond one-to-one with the protrusions 23.

[0042] By setting the groove 16 and the protrusion 23 to cooperate, the contact area is increased, the contact area after insertion and compression is improved, the friction is increased, and the installation and fixing strength of the circuit board 2 in the slot 22 is improved.

[0043] A second locking block 15 is symmetrically arranged on the side of the circuit board 2 away from the first locking block 14. The circuit board 2 is provided with multiple sets of through holes. The first locking block 14 and the second locking block 15 are provided with mounting holes corresponding to the through holes. A pin 18 made of insulating material is inserted through the mounting hole and the through hole.

[0044] The first locking block 14 and the second locking block 15 are fixedly installed on the circuit board 2 by setting the pin 18.

[0045] When installing the inner liner block 7 and the fixing block 8, the circuit board 2 needs to compress the spring 10 to avoid affecting the installation. Therefore, it is necessary to limit the position of the circuit board 2 during the installation process to prevent the circuit board 2 from resetting due to the reset force of the spring 10.

[0046] A connector plate 28 is provided at the end of the cable 11, and a plug 30 is provided on the connector plate 28. A terminal 17 is provided on the side of the circuit board 2 near the cable 11, which is fixedly connected to the plug 30. Multiple sets of telescopic columns 27 are provided on the inner wall of the end of the connector cover 3. The other end of the telescopic column 27 is fixed on the connector plate 28. The spring 10 is pressed between the outer wall of the middle section of the connector plate 28 and the telescopic column 27. A wing ring 9 is provided on the inner wall of the connector cover 3. The inner diameter of the wing ring 9 is larger than the outer diameter of the connector plate 28. A pair of side grooves 12 are arranged in a circumferential array on the side wall of the wing ring 9. One side of the outer end of the second locking block 15 extends to the top of the side groove 12, and the width of the second locking block 15 is smaller than the width between the side grooves 12. The gap between the inner liner block 7 and the wing ring 9 is larger than the height of the circuit board 2. The width of the first locking block 14 is equal to the width of the slot 22. The outer wall of the first locking block 14 is rounded. The length of the first locking block 14 is smaller than the depth of the slot 22.

[0047] The telescopic column 27 is used to achieve the telescopic and elastic installation of the connector plate 28. The upper groove 12 of the wing ring 9 and the second locking block 15 are used to temporarily limit the position of the circuit board 2.

[0048] The installation process is as follows: First, the cable 11 is pulled to the outside of the connector cover 3 for easy connection. Then, the fixing block 8 is screwed and rotated on the inner liner block 7, leaving a gap for the screw rotation so that the first opening 20 corresponds to the second opening 29. The electrical conduit 5 is installed laterally on the inner liner block 7 and the fixing block 8. Then, the fixing block 8 is rotated to achieve the misalignment of the first opening 20 and the second opening 29 to prevent the electrical conduit 5 from falling off. The cooperation between the plug 30 and the connector 17 is used to achieve the fixed connection between the circuit board 2 and the cable 11. Then, the circuit board 2 is squeezed inward so that the second locking block 15 extends along the side groove 12 to the inside of the wing ring 9. The circuit board 2 is rotated so that the second locking block 15 is misaligned with the side groove 12, forming a temporary limit on the circuit board 2.

[0049] Then, the inner liner 7 is installed on the connector cover 3. After installation, the electric tube 5 and the circuit board 2 are reset and rotated so that the second locking block 15 corresponds to the side groove 12. Under the reset force of the spring 10 and the traction of the electric tube 5, the first locking block 14 is inserted and pressed into the slot 22, forming the circuit board 2 fixed on the fixing block 8. Finally, the lamp cover 1 is installed, and the lamp cover 1 is used to wrap the light-emitting tube 6 to achieve uniform lighting.
