Problems solved by technology
[0004] The above solution can theoretically solve the problems of traditional assembly technology, but this solution has requirements for assembly space. If the PCB board is not very dense with components, there is not much interference around the pin positioning sleeve, and it is easy to assemble. On the PCB board, this solution is a very good choice; if there are too many components or relatively dense components on the PCB, there will be a problem of poor assembly when using this solution, and the pin positioning sleeve 3 will interfere with the surrounding components. In severe cases, components will be squeezed out, which requires additional and complicated correction work, and the assembly efficiency of PCBs with dense components will be extremely low, which will inevitably lead to an increase in labor costs for assembly

Embodiment Construction
[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.
[0034] Instructions attached figure 1 A structural schematic diagram of the positioning bracket 1 is given, on which there are terminal limiting grooves 2 and fool-proof bosses 3, the main function of which is to assemble on the support frame 6 for terminal positioning and prevent reverse installation.
[0035] Instructions attached figure 2 A schematic diagram of the structure of the fixed bracket 4 is given. Two small magnets 5 with a diameter of about 3.0 mm are embedded at both ends of the fixed bracket 4, and the main function is to make the fixed bracket adsorb on the support frame. Move the position of the fixing bracket so that the fixing bracket fixes the terminal together with the positioning bracket and t...

The invention provides a separated combination type clamp and a production technology using the same. The technical problem that a cross-shaped cylindrical terminal needs to be arranged on a PCB where elements are intensive is solved. Device placing and mounting can be accelerated, it is guaranteed that the terminal can be vertically subjected to wave soldering, the terminal does not need to be maintained after soldering is completed, the assembling efficiency is improved, and the labor cost is lowered.
Description
technical field [0001] The invention relates to a split and combined tool fixture and a production process using the fixture. Background technique [0002] In the electronics industry, especially the module power supply, it is often necessary to insert the cross cylindrical terminal into the through hole on the carrier PCB board, and then perform wave soldering to provide mechanical and electrical connections for different parts of the electronic component. The traditional assembly technology is to put the carrier PCB into the carrier fixture, then insert various components, and insert the cylindrical cross terminal into the through-hole terminal pad of the PCB cylinder, and finally the carrier fixture enters the wave crest through the transmission track The welding machine performs welding, so that the terminal is fixed on the PCB by welding. Since the hole diameter of the terminal pad hole on the PCB is larger than the diameter of the terminal, and the tolerance of the pad...
