Put and made using heat-protecting glass fiberboard, and be designed with multiple holes, once to load the contact of multiple electric connectors.
Preferably, the hole is Ф 2.6mm depth 20mm.
Preferably, the hole is 44.
Present invention also offers a kind of realize the technique that electric connector contact body is welded using described device, including it is following
Step：
S1, assembling contact assembly：The wire that tin is warded off through the end of a thread is carried out into pruning arrangement, wire is inserted into electric connector
Contact, white signal line insert contact interior insulation set, blue signal line insertion contact inside and outside insulation sleeve it
Between；Then it is loaded in the hole in the contact of wire insertion electric connector contact body welder, is fastened in hole by jump ring；
S2, in reflow ovens weld contact assembly：The temperature of six warm areas of reflow ovens of setting be respectively 190 DEG C, 180
DEG C, 185 DEG C, 210 DEG C, 255 DEG C, 260 DEG C, and set the transmission speed of conveyer belt in reflow ovens as 0.29 m/min or pass through
Time is 6 minutes, the electric connector contact body welder for assembling contact assembly is placed in reflow soldering, with biography
The transmission of band is sent, the welding of contact assembly is realized；After the completion of welding, electric connector contact body welder is put in normal temperature
Put and cooled down for a period of time, finally take out contact assembly from electric connector contact body welder.
(3) beneficial effect
The present invention devises a kind of electric connector contact body heat protector, solves thermal protection area when contact is welded
Heated protective problem, and using the technique that the arrangement achieves by the multiple electric connector contact bodies of reflow ovens automatic welding, it is real
The technique that the multiple contacts of small lot are once fixed, batch is once welded in reflow ovens is showed, instead of in prior art and adopt
Once the technique of weldering is manually blown to the contact of single electric connector with heat gun, production efficiency, product greatly improved
Uniformity and welding quality also obtained large increase.
