When the lamp tube holder is specifically assembled, firstly, the two inner conductive pins 400 are electrically connected to the PCB board 300, and the two outer conductive pins 200 are inserted into one pin hole 102, respectively, secondly, the two inner conductive pins 400 and the PCB board 300 are placed together in the accommodating cavity 101, and the two inner conductive pins 400 are inserted into one outer conductive pin 200 through one pin hole 102, respectively, and finally, the two outer conductive pins 200 are riveted, so that the outer conductive pins 200 and the inner conductive pins 400 realize fixed connection in mechanical structure.
Based on this structural design, when a plurality of lamp tubes of different specifications are produced, only the inner conductive pin 400 of the same type needs to be customized. In a specific assembling process, the inner conductive pins 400 are assembled to the corresponding PCB board 300. Compared with the prior art, there is no need to prepare a plurality of connectors to realize electrical connection with the outer conductive pins 200, thus reducing the material types that need to be prepared, and thereby reducing the material cost and the material management cost.
In an implementation of the present disclosure, the outer conductive pins 200 are made of copper material. Firstly, the copper material has high electrical conductivity, thus when being electrically connected to an external power supply device, the power receiving efficiency of lamp holder can be well ensured, and secondly, the copper material also has better processability, and is convenient for producing, processing and manufacturing.
In an implementation of the present disclosure, the inner conductive pins 400 are made of steel material. The steel material has better mechanical strength, thus, firstly, in the process of inserting the inner conductive pins 400 into the outer conductive pins 200, the inner conductive pins 400 are less likely to be deformed and bent, and secondly, when the outer conductive pins 200 are electrically connected to the external power supply device, the outer conductive pins 200 cannot be easily bent.
Referring to FIG. 2 and FIG. 3, in an implementation of the present disclosure, the two pin holes 102 are provided in a direction parallel to an opening direction of the accommodating cavity 101. In the process of placing the two inner conductive pins 400 and the PCB board 300 together in the accommodating cavity 101, the two inner conductive pins 400 and the PCB board 300 may be placed in the accommodating cavity 101 in an opposite direction following the opening direction of the accommodating cavity 101, and in the placing process, the two inner conductive pins 400 may be inserted into one outer conductive pin 200 via one pin hole 102, respectively, therefore, based on this structural design, the assembling efficiency of the lamp tube holder is improved.

Based on this structural design, in the process of inserting the two outer conductive pins 200 into one pin hole 102, respectively, the positioning of the positioning ring 220 can quickly insert and fit the outer conductive pins 200 into the pin hole 102, thus improving the assembling efficiency of assembling the outer conductive pins 200 to the housing 100, and thus improving the assembling efficiency of the lamp tube holder.
Specifically, the outer cylinder diameter of the outer pin cylinder 210 is equal to the aperture of the first pin hole, and an outer ring diameter of the positioning ring 220 is equal to the aperture of the second pin hole.
In an implementation of the present disclosure, the PCB board 300 is integrated with a driving circuit, and the driving circuit is configured to drive a light source board in the lamp tube.

When the lamp tube holder is specifically assembled, firstly, the two inner conductive pins 400 are electrically connected to the PCB board 300, and the two outer conductive pins 200 are inserted into one pin hole 102, respectively, secondly, the two inner conductive pins 400 and the PCB board 300 are placed together in the accommodating cavity 101, and the two inner conductive pins 400 are inserted into one outer conductive pin 200 through one pin hole 102, respectively, and finally, the two outer conductive pins 200 are riveted, so that the outer conductive pins 200 and the inner conductive pins 400 realize fixed connection in mechanical structure.
Based on this structural design, when a plurality of lamp tubes of different specifications are produced, only the inner conductive pin 400 of the same type needs to be customized. In a specific assembling process, the inner conductive pins 400 are assembled to the corresponding PCB board 300.
