Cap improvement

This creation relates to a cap improvement, and in particular to a cap that can be used in a bipolar power supply mode to the lamp.

According to the lamp of the early fluorescent lamp, the material of the fluorescent tube is mostly glass, and the inside of the fluorescent tube contains a small amount of mercury. Therefore, it is necessary to be very careful in taking or installing. If the fluorescent tube is accidentally broken, the internal mercury will flow out. If the environment causes injury, and the human body accidentally touches or adsorbs it, it will also cause poisoning; and the traditional fluorescent lamp is cheap, but its waste has the disadvantages of mercury pollution or fragility.

However, the current new generation of fluorescent lamps has been improved by using light-emitting diodes (LEDs), and its structure is the same as that of the early fluorescent lamps, so that it can be applied to the early lamp holders.

Referring to the first figure, it is pointed out that the structure of the conventional LED tube mainly includes a hollow tube body 11, a light-emitting module 12 and two external modules 13. The hollow tube body 11 includes a body 110 and a lamp cover 111 attached to the base body. The illuminating module 12 includes a circuit board 120 and a plurality of LEDs 121 coupled to the circuit board 120, and the circuit board 120 has electrical circuits electrically connected to the LEDs 121. The circuit has a side near the two sides of the circuit board 120. Two lead blocks 123. The two external modules 13 are coupled to the two ends of the hollow tube body 11. Each of the external modules includes a cap 130, a fixing block 131 and two terminals. The cap 130 is coupled to the base 110 by a bolt 133 which is screwed onto the base 110 by a bolt 133. The two terminals include an insert 136 and a guide post 137. The insert 136 is embedded in the fixing block 131 and one side is exposed under the fixing block 131 and is in soldering contact with the guiding block 123 on the outer side of the outer circuit board 120. The guide post 137 extends from an end surface of the insert 136 and protrudes from the cap 130 to the outside.

However, the shortcomings of the prior art are as follows:

1. The external module assembly operation is complicated and the assembly cost is high.

2. The welding quality is difficult to judge with the naked eye, so it is possible to produce small cracks, and if the level of the welding personnel is uneven, it is easy to affect the welding quality.

In order to conduct electricity, it is easy to assemble, and most people can replace the repair kit.

According to the above structural feature, the conductive terminal is provided with a contact portion and a fixing portion vertically connected to the contact portion.

The fixing portion has a through hole for fixing the columnar conductive portion.

According to the above structural feature, the cap is further provided with an insulating support body. One end of the insulating support body is fixed to the body, and the other end is located in the inner ring wall and is relatively fixed between the two conductive terminals.

According to the above structural feature, at least one circuit board is disposed on the inner side of the lamp tube, and a connecting seat is disposed at two ends of the circuit board, and the conductive terminal is inserted to form a conduction.

According to the above structural feature, the plurality of conductive terminals and the columnar conductive portion are integrally formed with the body in a buried molding manner.
