[0015] By adopting the above technical solution, the setting of the positioning block and the connecting hole facilitates the fitting of the lamp head body and the skeleton, and also facilitates the integration of the lamp head and the skeleton in the injection molding stage, effectively improving the work efficiency.

[0016] The present utility model is further configured such that grooves are provided on the outer wall of the through hole, and the number of the grooves is multiple groups, and the convex grooves are symmetrically distributed on the outer wall of the through hole.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0027] The following will describe the embodiments according to the overall structure of the present utility model.

[0028] An embedded skeleton and positive and negative electrode integrated injection molded lamp cap, as Figure 1 - Figure 4As shown in the figure, an internal thread 2 is provided on the inner wall of the lamp cap body 1, and a skeleton 3 is provided between the internal thread 2 and the lamp cap body 1. There are positive and negative connectors inside the lamp cap body 1. The positive and negative connectors pass through the skeleton 3 and extend to the inner wall of the lamp cap body 1. A through hole 32 is provided at the bottom of the skeleton 3, and multiple groups of connection holes 31 are provided on the side wall of the skeleton 3. Multiple positioning blocks 30 are installed on the top of the skeleton 3. Through the setting of the skeleton 3, installing the skeleton 3 in the lamp cap makes it convenient to integrally wrap the positive and negative poles of the lamp cap after embedding a layer of the skeleton 3 in the lamp cap, so that the positive and negative poles of the lamp cap body 1 and the skeleton 3 are wrapped and connected as a whole. The one-time injection molding and wrapping of the positive and negative poles have strong stability. Embedding the skeleton 3 in the lamp cap body 1 greatly improves the shortcoming of the low temperature resistance of the PVC material. Secondly, the lamp cap body 1 is not only small and delicate in appearance, but also improves the safety of the lamp cap. Through the setting of the positioning blocks 30 and the connection holes 31, the stability of the lamp cap and the skeleton 3 during the injection molding stage is effectively improved. The material makes the skeleton 3 more firmly embedded in the lamp cap body 1 through the connection holes 31, improving the stability of the product.

[0029] Please refer to Figure 1 - Figure 3 , the bottom of the skeleton 3 is flush with the bottom of the internal thread 2, and the top of the skeleton 3 is flush with the top of the internal thread 2. And the positioning blocks 30 are located at the top of the internal thread 2. The skeleton 3 is located between the internal thread 2 and the lamp cap body 1. The setting of the position of the skeleton 3 effectively improves the safety in the lamp cap and improves the heat resistance of the product.

[0030] Please refer to Figure 1 - Figure 4 , the materials of the skeleton 3 and the positioning blocks 30 are both metal materials, and the positioning blocks 30 and the connection holes 31 are on the same horizontal line, increasing the durability and stability of the lamp cap and effectively improving the safety of the lamp cap. Secondly, the skeleton 3 is embedded and wrapped in the lamp cap body 1, which is not only strong and high-temperature resistant, but also reduces the rusting phenomenon of the threaded lamp cap.

[0031] Please refer to Figure 2 、 Figure 4 , the skeleton 3 is in a circular ring shape, and a through hole 32 is provided at the bottom of the skeleton 3. And the diameter of the through hole 32 is smaller than the diameter of the skeleton 3. The skeleton 3 is integrally formed, making the skeleton 3 and the lamp cap body 1 connected as a whole, effectively reducing the manufacturing cost and having better fit. It is customized according to the size of the inner wall of the internal thread 2, effectively improving the quality of the product and at the same time improving the stability of the product.

[0032] Please refer to Figure 4 , the number of the positioning blocks 30 and the connection holes 31 is multiple groups, and the positioning blocks 30 and the connection holes 31 are symmetrically distributed on the skeleton 3. The setting of the positioning blocks 30 and the connection holes 31 facilitates the fitting of the lamp cap body 1 and the skeleton 3, and also facilitates the integration of the lamp cap and the skeleton 3 during the injection molding stage, effectively improving the work efficiency.

[0033] Please refer to Figure 1 - Figure 4 On the outer wall of the through hole 32, there are grooves, and the number of grooves is multiple groups, and the convex grooves are symmetrically distributed on the outer wall of the through hole 32. The setting of the through hole 32 is not only for facilitating injection molding, but also for conveniently wrapping the positive and negative electrodes of the lamp holder integrally, so that the positive and negative electrodes of the lamp holder body 1 are connected to the skeleton 3 as a whole, increasing the durability and stability of the lamp holder.

[0034] The working principle of the present utility model is as follows:

[0035] During the injection molding process of the lamp holder, the skeleton 3 is placed inside the lamp holder body 1, and the skeleton 3 is located between the internal thread 2 and the lamp holder body 1, and the bottom of the skeleton 3 is flush with the bottom of the internal thread 2. The height of the positioning block 30 is at the top of the internal thread 2, so that the skeleton 3 and the lamp holder body 1 are connected as a whole, effectively reducing the manufacturing cost, and having better fit, improving the safety of the lamp holder. Among them, by embedding the skeleton 3 into the PVC, not only makes the integrated lamp holder firm and high-temperature resistant, but also effectively reduces the rusting phenomenon of the threaded lamp holder. The settings of the positioning block 30 and the connecting hole 31 facilitate the fitting of the lamp holder body 1 and the skeleton 3, and also facilitate the connection of the lamp holder and the skeleton 3 into one body during the injection molding stage, effectively improving the work efficiency. Secondly, through the settings of the positioning block 30 and the connecting hole 31, the stability of the lamp holder and the skeleton 3 during the injection molding stage is effectively improved. The injected PVC material makes the skeleton 3 more firmly embedded in the lamp holder body 1 through the connecting hole 31, improving the stability and quality of the product. At the same time, the setting of the through hole 32 is not only convenient for feeding, but also convenient for integrally wrapping the positive and negative electrodes of the lamp holder, so that the positive and negative electrodes of the lamp holder body 1 are connected to the skeleton 3 as a whole, increasing the durability and stability of the lamp holder.
