[0005] The utility model provides a small laser radar detector, including diode assembly, diode tube body, tail fiber tube body, collimator and tail fiber, the diode assembly front end prefabricated has the lens, the diode assembly is fixed in the diode tube body through 353 glue, the tail fiber is coupled and is fixed at the collimator front end part, the collimator is fixed in the tail fiber tube body through 353 glue, the diode tube body tail part and tail fiber tube body head part are fixed through laser welding at the lap joint, and the diode tube body outer diameter is 1.9 mm.

[0006] The utility model has the advantages that the tube bodies are fixed through laser welding, have no influence on components, are stable in product performance, good in use effect, simple and compact in prefabricated lens structure, small in size, convenient to use, low in use cost, and effectively meet the use requirements. DRAWING EXPLANATION

[0007] Figure 1 It is a structural schematic view of one embodiment of the utility model. CONCRETE IMPLEMENTING METHOD

[0008] The preferred embodiments of the utility model will be described in detail below with reference to the drawings.

[0009] Please refer to Figure 1 A small laser radar detector, including diode assembly 1, diode tube body 2, tail fiber tube body 3, collimator 4 and tail fiber 5, the front end of diode assembly 1 is prefabricated with lens, diode assembly 1 is fixed in diode tube body 2 through 353 glue, tail fiber 5 is coupled and fixed at the front end of collimator 4, collimator 4 is fixed in tail fiber tube body 3 through 353 glue, the tail of diode tube body 2 and the head of tail fiber tube body 3 are fixed by laser welding at the lap joint, and the laser welding mode does not produce bubbles and has no influence on components, so that the product performance is more stable, the outer diameter of diode tube body 2 is 1.9mm, and the lens is prefabricated on the diode in advance, so that the diode tube body can be smaller.

[0010] The utility model discloses the beneficial effect lies in: the laser welding is fixed between the pipe body, does not produce bubble and has no influence on components, and the product performance is stable, and the use effect is good, and the lens structure of prefabrication in advance is more simple and compact, and the volume is small, and the use is convenient, and the use cost is low, and effectively satisfy the use requirement.
