[Prior Art] Please refer to the first and second figures to indicate the structure of the conventional LED tube. • Mainly include a hollow tube body 1, a light-emitting module 2 and two external modules 3. The hollow body 1 includes a body 10 and a lamp cover 11 attached to the body. The lighting module 2 includes a plurality of circuit boards 20 and a plurality of LEDs 21 coupled to the circuit boards 20. The plurality of circuit boards 2 are screwed onto the base body by bolts 22, and each circuit board 20 has a circuit electrically connected to the LEDs 21, and the circuit has two at the side edges of the circuit board 20 respectively. Lead block 23. The opposite guiding block 23 of the phase circuit board 20 is provided with a wire 24 for electrical connection. The two external modules 3 are coupled to the two ends of the hollow tube 1. Each of the external modules includes an end cover 30, a fixing block 31 and two terminals 32. The end cover 30 is coupled to the base body 1 . The fixing block 31 is screwed onto the base body 10 by bolts 33 and has two recesses 34 . The two recessed slots 34 have a gap toward the side of the circuit board 20 . 35. The two terminals 32 include an insert 36 and a guide post 37. The insert 36 is embedded in the pocket 34 and is partially exposed by the recess 35 and is in contact with the leading block 23 on the outer side of the outer circuit board 20. The guide post 37 extends from an end surface of the insert 36 and protrudes from the end cover 3 to the outside tn 3 201142184. However, the conventional LED tube generates, shouts and uses the same in the following. There are a number of problems: - the two terminals 32 are protruded by the insert block 36 from the portion of the fixed block 31 and the upper portion of the plate 20 is electrically connected. Therefore, it is easy to use the fixed block 31 or the terminal. The manufacturing tolerance of 32 is either an error in the grouping, and the block 36 cannot be in contact with the guiding block 23, or the contact between the two is not tight, thereby causing inconsistency or contact. The problem of poor sexual connection. 2. The plurality of circuit boards 20 are screwed onto the body ίο by bolts 22, respectively, and the fixing block 31 is screwed onto the body ^ by a thread check 33. This type of screw lock requires a _contact lock tool, and it takes a lot of time, so it will affect its assembly efficiency. 3. The phase connection block 23 of the adjacent circuit board 20 is formed by soldering a wire 24 to form an electrical connection, so that assembly is troublesome and inconvenient. • In particular, the manner in which the wire 24 is soldered is more likely to occur if the wire 24 is detached or the contact is poor. Moreover, the wire 24 cannot be pre-welded during assembly, but the welding process can be performed after the plurality of circuit boards 20 are locked to the seat body 1 , and this causes troubles in welding processing and assembly. .
