[0003] During the production process of the inner core of the lamp holder with this structure, the contact piece is directly inserted into the wire for conduction, so there are relatively high requirements on the cross-sectional size of the wire and the centering degree of the copper wire. As a result, there are problems of excessively high wire costs and low production yields. In addition, the matching finished light bulbs require filaments, filament brackets, and lamp holders. There are many accessories and many assembly steps, so there are problems of high costs and low production efficiency.

[0004] Another structure of the lamp holder is to weld two pins on the wick module, and install two corresponding sockets on the wire end, and power is turned on by inserting the pins into the sockets;

[0005] During the production process of the lamp holder core of this structure, since it is necessary to weld the pins, install the sockets, and manually insert the pins into the sockets, there is a problem of low production efficiency and it cannot meet the needs of large-scale production.

[0051] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0052] like Figure 1-5 As shown, the utility model provides a plug-in type lamp holder inner core structure that is convenient for automatic assembly, including:

[0053] The connecting housing 100 is arranged to be through-connected from front to back;

[0054] The wick module 200 and the conductive spring 300 are respectively inserted from the front and rear ends of the connecting shell 100.

[0055] The circuit board portion of the insertion end of the wick module 200 is provided with conductive copper foil (not shown in the figure);

[0056] When the conductive spring clip 300 is inserted into the connection shell 100, the insertion end of the conductive spring clip 300 is pressed against the conductive copper foil, and the other end of the conductive spring clip 300 is located outside the connection shell 100 and is used to contact the wire for electricity. The conductive spring clip 300 can be contacted with the wire for electricity by stamping, puncture or welding. To ensure the reliability of the connection, stamping and welding are preferably used.

[0057] The inner core structure of the lamp holder of the above structure omits the filament bracket and the lamp holder, which not only reduces the cost, but also eliminates the bulb assembly process to improve production efficiency. At the same time, the copper wire and the contact piece are connected by stamping or welding, which does not have too many requirements on the cross-section of the copper wire while ensuring the connection reliability.

[0058] In addition, the lamp cap inner core structure in this embodiment has at least the following advantages:

[0059] 1. Simplify the assembly process: This design eliminates the steps of soldering pins and manually matching pins and sockets through direct contact between the conductive copper foil on the wick module 200 and the conductive spring 300, greatly simplifying the assembly process and making the entire assembly process more convenient and faster;

[0060] 2. Improve production efficiency: Since welding and delicate manual docking operations are eliminated, the production line can be more easily automated or semi-automated, significantly increasing the output of products per unit time, meeting the requirements of large-scale production;

[0061] 3. Reduce costs: The increase in automation reduces the reliance on manual labor, which can effectively reduce labor costs in the long run. At the same time, eliminating the welding step can also reduce material loss and energy consumption, further reducing costs;

[0062] 4. Enhanced reliability: Compared with the crimping method of the conductive copper foil, the conductive spring 300 can provide a more stable electrical connection by welding, especially in a vibrating environment, which reduces the risk of connection failure caused by poor welding and improves the durability and safety of the product;

[0063] 5. Easy to maintain and replace: This modular design is not only easy to produce, but also makes the subsequent maintenance or replacement of the wick module 200 easier and faster, which is conducive to extending the product life and improving the user experience.

[0064] In summary, this innovative plug-in lamp holder core structure provides important technological innovation for the lighting industry through its convenient assembly method, efficient production model, and enhanced product reliability, helping companies to improve their competitiveness and adapt to rapidly changing market demands.

[0065] Preferably, the insertion end of the wick module 200 has two contact ends 210, and the conductive copper foil is attached to the two contact ends 210;

[0066] Furthermore, a positioning groove 220 is provided between the two contact ends 210 of the wick module 200, and a positioning block 110 is correspondingly provided at one end of the connecting housing 100. The positioning block 110 is adapted to the shape and size of the positioning groove 220. When the wick module 200 is inserted into the connecting housing 100, the positioning block 110 is embedded in the positioning groove 220.

[0067] The cooperation between the positioning block 110 and the positioning groove 220 ensures the accurate positioning of the wick module 200 during the insertion process, avoids position deviation during insertion, and ensures that the subsequent conductive spring 300 can automatically press against the conductive copper foil of the wick module 200 after being inserted into the connecting shell 100.

[0068] Preferably, the wick module 200 is provided with two positioning holes 230, and the connecting housing 100 is provided with a positioning protrusion 120 adapted to the positioning holes 230. When the wick module 200 is inserted into the connecting housing 100, the positioning protrusion 120 is inserted into the positioning hole 230;

[0069] The positioning stopper 110 and the positioning protrusion 120 are located at the same end of the connecting shell 100 . When the wick module 200 is inserted until the positioning stopper 110 is completely embedded in the positioning groove 220 , the positioning protrusion 120 can be inserted into the positioning hole 230 .

[0070] That is to say, combined with the original positioning groove 220 and the positioning block 110 design, the newly added positioning hole 230 and the positioning protrusion 120 form a set of precise positioning system in the vertical direction, ensuring that the wick module 200 can be firmly and accurately fixed not only in the axial direction but also in the radial direction. This dual positioning mechanism greatly improves the accuracy and efficiency of assembly.

[0071] Preferably, a plurality of guide plates 130 are provided at intervals in the connection shell 100, and a guide channel is formed between two guide plates 130. The conductive plug is inserted inwardly along the guide channel. The guide channel provides a precise path for the insertion of the conductive spring clip 300, ensuring that the conductive spring clip 300 can reach the predetermined position smoothly and unimpeded, while reducing the risk of damage during the insertion process, and protecting the structural integrity and electrical performance of the conductive spring clip 300.

[0072] Furthermore, the two guide plates 130 for forming the guide channel are connected to each other and form a positioning convex surface 140 and an accommodating space 150 for inserting the conductive spring sheet 300 .

[0073] Specifically, the conductive spring clip 300 is bent to form an elastic contact end surface 310. When the conductive spring clip 300 is inserted along the guide channel, the insertion end of the conductive spring clip 300 is inserted into the accommodating space 150. At the same time, the conductive spring clip 300 is abutted against the positioning convex surface 140. At this time, the elastic contact end surface 310 can automatically press against the conductive copper foil of the wick module 200.

[0074] Such a design makes the installation of the conductive spring 300 easier and faster. Workers or automated equipment only need to insert it according to the guide path, which reduces assembly complexity and time and improves the overall assembly efficiency and production speed.

[0075] Preferably, the portion of the conductive spring 300 located outside the connection shell 100 is bent to form a wiring portion 320, and the wire passes between the wiring portions 320 of the two conductive springs 300. The wiring portion 320 and the wire can be fixed and energized by stamping, puncture or welding.

[0076] When the conductive spring 300 is fully inserted into the connection housing 100 , the bent end surface of the wiring portion 320 connected to the conductive spring 300 presses against the outer end surface of the guide plate 130 , further ensuring the automatic positioning of the conductive spring 300 after insertion.

[0079] It is worth mentioning that the connection housing 100 is connected to the mounting plate 410, and the connection method thereof can be set to an integral connection or a detachable connection. For example, in order to improve production efficiency, in the present embodiment, the connection housing 100 and the entire lamp holder 400 are produced by integral injection molding, that is, the connection housing 100 and the mounting plate 410 are an integral connection structure, but replacing the connection housing 100 and the mounting plate 410 with a detachable connection structure is also a common technical means for those skilled in the art;

[0080] Among them, one end of the connecting shell 100 for inserting the wick module 200 is located in the wick installation cavity 420, and one end of the connecting shell 100 for inserting the conductive spring 300 is located in the wire accommodating cavity 430.

[0081] Preferably, the connecting housing 100 is used to insert one end of the conductive spring sheet 300, and a wire fixing groove 160 is provided on its end surface, and a wire sheath fixing groove 440 is provided on the circumferential outer wall of the wire accommodating cavity 430;

[0082] During the actual installation process, the wire after the sheath is stripped is embedded in the wire fixing groove 160, and the wire wrapped with the sheath is embedded in the wire sheath fixing groove 440. Then, the wiring part 320 of the conductive spring 300 is bent and contacted with the wire after the sheath is stripped, so as to complete the preliminary fixation of the wire and ensure smooth power supply.

[0083] Furthermore, it also includes a back cover 600, which is connected to the lamp holder 400 and closes the wire receiving cavity 430;

[0084] Specifically, after the wires are fixed in the wire accommodating cavity 430, the wire accommodating cavity 430 is filled by injecting glue, which, on the one hand, ensures the stability of the wires after installation and the stability of power supply, and on the other hand, also plays a role in sealing and waterproofing the entire wire accommodating cavity 430. Subsequently, the back cover 600 is used to seal the wire accommodating cavity 430 to complete the assembly of the waterproof lamp holder.

[0085] The back cover 600 and the lamp holder 400 in this embodiment are connected by snap-fitting, or they may be replaced by threaded connection or other common connection methods known to those skilled in the art.
