Abstract
The invention discloses a heat treatment process for a jack of an electric connector, which comprises the following steps that: a special opening-shrinking tool is adopted to carry out hole-shrinking on the jack; after the furnace temperature for heat treating reaches 290+/-10 DEG C, the opening-shrinking tool and the embedded jack are fed into a furnace to be subjected to heat treatment; after the furnace temperature rises to 290+/-10 DEG C again, timing is started; and heat preservation is carried out at the furnace temperature of 290+/-10 DEG C for 3 hours, and then discharging and air cooling are carried out. According to the invention, the opening-shrinking effect of the opening part of the jack is favorable without a clearance, the jack is stressed evenly, the insertion and extraction force of the jack is no less than 2.45N, the connecting requirement of the electric connector is met, the connection is firm, the time is saved, the efficiency is high, and the signal is stable.
Description
Technical field
The present invention relates to a kind of heat treatment process for jack of electric connector, belong to electric connector heat treatment process technical field.
Background technology
Jack is one of crucial link of Radio Control System, opening has four open slots, after requiring machine work to complete, carry out heat treatment shaping by closing up after colliding, the internal stress that produces to eliminate groove mechanical processing, stable dimensions obtains good elasticity and elastic stability, satisfies the specification requirement that contact engaging and separating force is not less than 2.45N.existing jack heat-treatment processing process is: first the jack openings groove location is closed up, usually adopting the mild steel wire of Φ 0.2mm to tie up the open slot position makes four opening sheets of opening part collide, when closing up with wire binding, the closing in effect is bad, there is certain interval all the time in opening, close up inhomogeneous, different operator in addition, the tightness of tying up is different, the closing in gap is inhomogeneous, after causing the jack heat treatment shaping, contact engaging and separating force hangs down the requirement that even do not meet the specification, jack relaxes because thermal expansion causes steel wire when heat treatment shaping simultaneously, cause jack closing in position discontinuity or stressed reduce even not stressed, thereby cause the heat treatment shaping contact engaging and separating force low even unqualified.On the other hand, the stove mode that enters that jack heat treatment is at present adopted is to enter stove to temperature, owing to having larger heat loss when entering furnace operating, furnace temperature reduces rapidly, because general heat treatment temperature retention time is to begin timing when entering stove, temperature retention time is not enough again, and heat is inadequate, cause eliminating internal stress not thorough, poor dimensional stability, elastic stability is poor, and contact engaging and separating force is low, thereby affect the heat treatment shaping final mass, contact engaging and separating force does not reach the specification requirement of 2.45N.
Summary of the invention
The objective of the invention is provides a kind of electric connector jack heat-treatment processing process in order to overcome the deficiencies in the prior art, improves jack heat treatment shaping quality, satisfies electric connector and the jack contact engaging and separating force is not less than the specification requirement of 2.45N.
Technical scheme of the present invention is to adopt following steps:
1, the design specialized seaming tool closes up to the jack openings position, guarantees to close up good, stressed evenly.Seaming tool is sheet material, adopts the 45# steel making, opens 91 closing in holes, after machining and through processings of turning blue, places the preservation of 20# machine oil stand-by.One secondary frock can satisfy the heat treatment of 91 workpiece simultaneously, seaming tool should guarantee the respond well gapless of jack openings position closing in, make again each jack stressed evenly, after guaranteeing heat treatment shaping, contact engaging and separating force is not less than 2.45N, the while handled easily, save time, efficient is high, and does not damage socket surfaces.
2, Technology for Heating Processing step:
(1) first clean jack with gasoline, then clean to clean with absolute ethyl alcohol, naturally dry;
(2) jack is packed into seaming tool inserts seaming tool with the jack oral area and closes up, and must guarantee that four opening sheets of jack collide, and forms the annular of a sealing, gapless;
(3) after furnace temperature to be heated reaches 250-320 ℃, seaming tool is put into equipment for Heating Processing in the lump together with the jack of packing into heat-treats, because entering stove, jack cause temperature to reduce, treat that furnace temperature rises to again 250-320 ℃ of beginning timing, insulation is 3-4 hour under furnace temperature 250-320 ℃ condition, then take out, air cooling is to room temperature.
Heat-treatment processing process of the present invention can effectively be eliminated the jack internal stress, improves product size stability, improve elasticity and elastic stability, fully guarantee thermal treatment quality and effect, satisfy the specification requirement that contact engaging and separating force is not less than 2.45N, product is qualified to be reached more than 99%.
Beneficial effect of the present invention:
1. utilize the special closing-in frock that jack openings is partly closed up, close up good, stressed even, easy to operate, to save time, efficient is high, good springiness, contact engaging and separating force is high, is far longer than 2.45N, surpasses the technical conditions requirement;
2. improved the heat treatment holding temperature, the thermal loss when compensation enters furnace operating compensates each jack each several part temperature and reaches the even needed time, guarantees effectively to eliminate internal stress, improves product size stability, improves elasticity and elastic stability;
3. the present technique qualification rate is high, can reach 100%, reduces the human and material resources waste that causes reduction larger because doing over again, reprocessing, and greatly enhances productivity simultaneously.
