Description

Technical Field

[0001] The present invention relates to the technical field of lamp holder clamps, in particular to a lamp holder clamp. Background Art

[0002] LED lamps are common lighting devices currently available. Common LED lamps and other lighting devices are composed of light-emitting devices, electric boards and shells, which are assembled into finished lighting devices through assembly.

[0003] During the assembly process, the order of assembly is extremely important. Since most light-emitting devices are tube-mounted and the wires connected to their circuits are wrapped in wire tubes, during the assembly process, the parts need to be inserted into the outer casing before the circuit is connected.

[0004] In the actual assembly process, since the outer shell and the lining fixing parts are provided with through holes for accommodating the insertion of the electric wire tube, the size requirements of the through hole and the electric wire tube need to be met. 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 for assembly. As a result, the other end needs to be smaller than the inner diameter of the through hole when plugged in, thereby limiting the size of the light-emitting device. In addition, the common existing connection method is mostly threaded rotation connection. Therefore, after the circuit board and the lining block are fixedly connected, the threaded rotation installation will drive the rotating spiral of the connection position between the circuit board and the cable, thereby affecting the connection stability of the circuit and easily causing the connection to fall off.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 to 7 , the present invention provides a technical solution: Example 1: A lamp holder fixture includes a lampshade 1, a light-emitting component and a connector cover 3. The light-emitting component includes a light-emitting tube 6 for illuminating, a circuit board 2 for controlling the light-emitting tube 6 and an electric tube 5 for connecting wires. An electric contact connector 4 for an external power supply is provided on the outside of the connector cover 3.

[0021] The circuit board 2 is powered by an external power source through the electric contact connector 4, so that the light-emitting tube 6 emits light to achieve the purpose of lighting. The electric tube 5 is used to realize the electrical connection between the circuit board 2 and the light-emitting tube 6.

[0022] An inner lining block 7 is provided inside the connector cover 3, and a detachable fixing block 8 is provided in the inner lining block 7. A gap component is provided in the middle of the inner lining block 7 and the fixing block 8 to facilitate the installation of the electrical pipe 5. An open groove is provided on one side of the inner lining block 7 and the fixing block 8 to communicate with the gap component in a side direction. A first card block 14 is provided at one end of the circuit board 2 close to the fixing block 8, and a card slot 22 is provided on the fixing block 8 to be plugged and fixed with the first card block 14. The circuit board 2 and the electric shock connector 4 are electrically connected through a folded cable 11, and a spring 10 is elastically pressed between the circuit board 2 and the inner wall of the connector cover 3.

[0023] By setting an open groove, the lateral installation of the electric pipe 5 on the lining block 7 and the fixing block 8 is achieved, and then the electric pipe 5 is installed on the pore assembly, so that the electric pipe 5 passes through the lining block 7 and the fixing block 8. The spring 10 is used to realize the elastic extrusion of the circuit board 2 during the installation of the lining block 7 and the fixing block 8, so that its position will not affect the installation of the lining block 7 and the fixing block 8. The reset elastic force of the spring 10 and the traction on the electric pipe 5 are used to make the first clamping block 14 clamped in the clamping slot 22, thereby achieving the purpose of fixed assembly and installation, and ensuring the stability of the circuit connection.

[0024] Working principle: First, the lateral installation of the electric tube 5 on the lining block 7 and the fixed block 8 is realized through the open groove, and then the circuit board 2 is connected to the cable 11, and the spring 10 is squeezed to make the circuit board 2 move into the inner cavity of the connector outer cover 3 to ensure that the installation position of the circuit board 2 will not affect the installation of the lining block 7 and the fixed block 8. At this time, the circuit board 2 and the lining block 7 and the fixed block 8 are not fixed, so the threaded rotation installation of the lining block 7 and the fixed block 8 drives the rotation of the circuit board 2 and the electric tube 5, ensuring the stability of the connection. After the installation of the lining block 7 and the fixed block 8 is completed, the reset elastic force of the spring 10 and the traction on the electric tube 5 are used to make the first clamping block 14 clamped in the clamping slot 22, thereby achieving the purpose of fixed assembly installation and ensuring the stability of the circuit connection.

[0025] Example 2: Based on Example 1, the lampshade 1 is threadedly installed on one end port of the connector outer cover 3, the light-emitting tube 6 extends into the inner cavity of the lampshade 1, and a connecting column 13 is fixed to the other end of the connector outer cover 3. One end of the connecting column 13 is connected to the electrical connector 4, and the other end of the connecting column 13 is connected to the cable 11.

[0026] The connection between the cable 11 and the electric contact connector 4 is achieved by providing a connecting post 13 , so that power can be supplied to the circuit board 2 after the external power source is connected.

[0027] The pore assembly includes a first through hole 21 passing through the inner lining block 7 and a second through hole 26 passing through the fixed block 8. The opening groove includes a first opening 20 set on the inner lining block 7 and a second opening 29 set on the fixed 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 electrical pipe 5 is smaller than the inner diameter of the first through hole 21 and the second through hole 26.

[0028] The lateral installation of the electrical pipe 5 is achieved by providing an open slot and a hole assembly.

[0029] The inner cavity port of the joint outer cover 3 is provided with a second internal thread 31, the outer wall of the inner lining block 7 is provided with a first external thread 24 which is installed in cooperation with the second internal thread 31, one side of the inner lining 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 which is installed in cooperation with the first internal thread 19.

[0030] By setting internal and external threads, the fixing block 8 is fixedly installed on the inner lining block 7, and the inner lining block 7 is fixedly installed in the inner cavity of the joint outer cover 3. At the same time, by utilizing the rotational fit of the threads, after the inner lining 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 closing the second opening 29 and preventing the electric tube 5 from falling off laterally.

[0031] Example 3: Based on Example 2, the card slots 22 are arranged as multiple groups distributed in a circular array, and the inner wall of the card slots 22 is provided with multiple groups of protrusions 23 distributed at intervals. The first card block 14 is plugged and installed along the card slots 22, and the front and rear side walls of the first card block 14 are provided with pressing grooves 16 corresponding to the protrusions 23, and the pressing grooves 16 correspond one-to-one to the protrusions 23.

[0032] By providing the cooperation between the pressing groove 16 and the protrusion 23 , the contact area is increased, the contact area after plugging and extrusion is increased, the friction force is increased, and the installation and fixing strength of the circuit board 2 in the card slot 22 is improved.

[0033] A second clamping block 15 is symmetrically arranged on one side of the circuit board 2 away from the first clamping block 14. A plurality of through holes are provided on the circuit board 2. Mounting holes corresponding to the through holes are provided on the first clamping block 14 and the second clamping block 15. Pin rods 18 made of insulating material are inserted through the mounting holes and the through holes.

[0034] The first clamping block 14 and the second clamping block 15 are fixedly mounted on the circuit board 2 by providing the pin rod 18 .

[0035] When installing the lining block 7 and the fixing block 8, the circuit board 2 needs to squeeze 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 being reset due to the reset force of the spring 10.

[0036] 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 that is fixedly connected to the plug 30 is provided on the side of the circuit board 2 near the cable 11. Multiple groups of telescopic columns 27 are provided on the inner wall of the end of the connector cover 3, and the other ends of the telescopic columns 27 are fixed to the connector plate 28. The spring 10 is pressed between the connector plate 28 and the outer wall of the middle section of the telescopic columns 27. A wing ring 9 is provided on the inner wall of the connector cover 3. The middle inner diameter of the wing ring 9 is larger than the outer diameter of the connector plate 28. A pair of side grooves 12 distributed in a circumferential array are provided on the side wall of the wing ring 9. One side of the outer end of the second clamping block 15 extends to directly above the side groove 12, and the width of the second clamping block 15 is smaller than the inter-groove width of the side grooves 12. The gap between the inner lining block 7 and the wing ring 9 is greater than the height of the circuit board 2. The width of the first clamping block 14 is equal to the width of the clamping slot 22. The outer wall of the first clamping block 14 is rounded, and the length of the first clamping block 14 is less than the depth of the clamping slot 22.

[0037] The telescopic column 27 is provided to realize the telescopic elastic installation of the connector plate 28 , and the position of the circuit board 2 is temporarily limited by the cooperation between the upper groove 12 of the wing ring 9 and the second clamping block 15 .

[0038] The installation process is as follows: first, pull the cable 11 to extend to the outside of the connector cover 3 for easy connection, then thread the fixing block 8 and install it on the inner lining block 7, and retain a gap for thread rotation so that the first opening 20 corresponds to the second opening 29, and the electrical pipe 5 is installed laterally on the inner lining block 7 and the fixing block 8, and then continue to rotate the fixing block 8 to achieve the misalignment of the first opening 20 and the second opening 29 to prevent the electrical pipe 5 from falling, and use the plug 30 and the terminal head 17 to achieve fixed connection between the circuit board 2 and the cable 11, and then squeeze the circuit board 2 inward so that the second block 15 extends along the side groove 12 to the inner side of the wing ring 9, and rotate the circuit board 2 so that the second block 15 is misaligned with the side groove 12, forming a temporary limit for the circuit board 2.

[0039] Then install the lining block 7 on the connector cover 3. After the installation is completed, reset and rotate the electric tube 5 and the circuit board 2 so that the second clamping block 15 corresponds to the side groove 12. Under the reset elastic force of the spring 10 and the traction of the electric tube 5, the first clamping block 14 is inserted and pressed into the clamping groove 22, thereby fixing the circuit board 2 on the fixing block 8. Finally, install the lampshade 1 and use the lampshade 1 to wrap the light-emitting tube 6 to achieve uniform lighting.
