Lamp connector improvement

The present invention relates to a lamp connector improvement, in particular to a lamp connector that allows a user to form a contact conduction by a simple plug-in action, and is suitable for a fluorescent tube, a power-saving lamp or the like. Improvement.

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 external module includes an end cover 130, a fixing block 131 and two terminals. The end cap 130 is coupled to the seat body by a bolt 133 At 110, the fixing block 131 is screwed onto the base 110 by bolts 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 end cover 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 welding personnel is uneven, it is easy to affect the welding quality.

3. Generally, the LED tube is still extended to the conventional lamp holder structure. When the LED tube is inserted into the socket of the conventional lamp holder structure, the power supply can be turned on because the rotation of the LED lamp is required to be rotated by 90 degrees, so that the illumination surface of the LED tube is also deviated. At 90 degrees, the side below the LED tube cannot be illuminated.

In view of this, the present invention is to provide a lamp connector connector for a fluorescent tube, a power saving lamp or the like, which can be used for the user to form a contact conduction by a simple plugging action, for the main purpose thereof. By.

In order to achieve the above, the lamp tube of the present invention is provided with a light source module and a two-end cover, and the connector is used for connecting the two end covers to the two end sides of the light source module respectively. The connector comprises at least: The insulating body, the conductive sheet and the connecting terminal, the insulating body is provided with a slot, and the connecting terminal is disposed in the slot and connected to the conductive sheet.

Wherein the connection terminal is provided with at least two elastic terminal portions, through each end The conductive terminal of the cover is directly inserted into the connector, and is in contact with each of the elastic terminal portions to conduct electric power, so that the assembly is easy, and the repair kit can be replaced by a general person.

According to the above main technical features, the bottom of the insulating body is provided with at least one protruding positioning post.

According to the above main technical features, the two sides of the insulating body respectively form two openings, and the two soldering portions of the conductive sheet can be pierced.

According to the above main technical feature, an annular connecting portion is formed between the second guiding portion and each of the elastic terminal portions.

According to the above main technical features, the connection terminal is provided with three elastic terminal portions, and each of the elastic terminal portions is disposed at an angle of 120 degrees.

According to the above main technical features, the first guiding portion may be provided with a through hole for the second guiding portion of the connecting terminal to be sleeved.

The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples.
