Description

Single-fiber bidirectional component pin switching resistance welding tool

Technical Field

The utility model belongs to the field of optical devices, and relates to a resistance welding tool capable of switching the BOSA pin direction of a single-fiber bidirectional assembly.

Background

Conventional fiber optic transmission is single fiber, unidirectional, such that two fibers are required to achieve bidirectional communication. The BOSA is a single-fiber bidirectional technology which can simultaneously transmit forward and reverse directions in two directions in one optical fiber, and does not interfere optical signals in the transmitting and receiving directions, and is a structure which combines transmitting and receiving. The work that two optical fibers can finish two wavelengths of bidirectional transmission originally can be finished by only using one optical fiber, and the transmission quantity of the existing optical fiber is doubled, so that the optical fiber resource is greatly saved. The single-fiber bidirectional component is a device comprising a laser, a 45-degree optical filter, a 0-degree optical filter, a ferrule, a receiver and a metal square base. The parts of the 0 degree optical filter, the 45 degree optical filter, the inserting core and the like are connected together through the metal base piece. The laser LD emits downlink optical signals, transmits light through the 45-degree optical filter and finally emits the light into an optical fiber connected with the ferrule; the upward optical signal from the optical fiber is reflected by the 45-degree optical filter, the vertical horizontal line is reflected upwards to the 0-degree optical filter, the 0-degree optical filter filters out light with other wavelengths and only transmits the downward optical signal to the avalanche photodiode APD, and the APD converts the upward optical signal into photocurrent for a subsequent system to use. The optical filter is a key element, and the function of the 45-degree optical filter is very important. The reflective film mainly aims at the receiving end, the assembly precision of the 45-degree optical filter directly influences the direction of reflected light, and the influence on the production coupling of the optical receiving end is very large. A single-fiber bidirectional assembly bosa (bidirectional Optical subassembly) is a core device of modern Optical communication. The single-fiber bidirectional component is a photoelectric conversion device integrating transmitting and receiving, and adopts an optical fiber to realize the function of bidirectional data transmission. A common single-fiber bidirectional module generally uses two wavelengths for transmitting and receiving optical signals. In the network installation process, optical modules with different wavelengths need to be adopted, the situations of misuse and mixed use of the optical modules are easy to occur, and the network construction and operation cost is increased. Meanwhile, in a wavelength division multiplexing system, a single-fiber dual-wavelength optical module requires that all users use a specific wavelength for uplink transmission and another wavelength for downlink transmission, so that the bandwidth utilization rate is low. The ROSA and the optical transceiving shared structure are packaged in the shell, and the optical transceiving shared structure is provided with three ports which are respectively connected with the wavelength division multiplexer of the TOSA, the wavelength division demultiplexer of the ROSA and the optical interface of the shell. In the current BOSA system, the laser and detector are arranged at a vertical angle, and the isolator and the wavelength division multiplexing system are used independently. The design in the prior art has the defects of complex structure, difficult installation, high manufacturing cost and the like. Because the proportion of the BOSA in the total cost of the optical transmission equipment shows a gradually increasing trend, the cost of the BOSA is controlled and mastered, the demands of optical module manufacturers on the BOSA are different, the BOSA is matched with the difference of the wiring of a PCB (printed circuit board), when the BOSA is packaged, the pin definition directions of the BOSA are more and more diversified, and the tool meets the advantages of various BOSA pin definitions and is very favorable for use and management.

SUMMERY OF THE UTILITY MODEL

The present invention has the following advantageous effects.

According to different pin directions of a single-fiber bidirectional component BOSA, 2 pillars can be distributed on a circumferential chassis of a welding base 1 at intervals of 180 degrees and used for supporting an upper cover, a resistance welding space of the welding base 1 and a welding upper cover 3 is reserved, 4 pin switching slotted holes 6 are distributed on the insulation upper cover 3 at intervals of 90 degrees, the direction of the covered pins is more, and multidirectional random switching is met when a laser is in resistance welding with a three-way metal square part. In practical application, no matter the single-fiber bidirectional component BOSA pin direction of batch production or the BOSA pin direction of customized production, especially the single-fiber bidirectional component BOSA pin direction of customized production, time and cost for independently developing a tool can be saved, the tool can be shared with the tool for batch production of the single-fiber bidirectional component BOSA pin direction, and the use efficiency of a resistance welding tool is improved. The problem that the direction is accurate when BASE and TO56 lasers are subjected TO resistance welding is effectively solved, and various pin directions can be met.

The welding direction is accurate. The utility model utilizes the pin switching slot hole 6 for switching the pin direction of the single-fiber bidirectional component BOSA in multiple directions, high-temperature molten metal can be solidified in a short time through voltage difference to form integrated welding, and the fixture is fixed, so that the problem that the fixture can meet various pin directions when a BOSA laser is in resistance welding with a three-way metal square part is effectively solved, and the welding direction is accurate and reliable.

The utility model is suitable for light source laser assemblies, single-fiber bidirectional assemblies, single-fiber three-way assemblies and optical transceiver assemblies which cover more pins.
