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 electric connector jack Technology for Heating Processing, 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, require machine work to accomplish after, after colliding, heat-treat typing through closing up; To eliminate the internal stress that groove mechanical processing produces; Stable dimensions obtains better elastic 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: earlier the jack openings groove location is closed up, adopt the mild steel wire of Φ 0.2mm to tie up the open slot position usually and make 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, and it is inhomogeneous to close up, in addition different operation person; The tightness of tying up is different; The closing in gap is inhomogeneous, causes the low requirement that even do not meet the specification of jack heat treatment typing back contact engaging and separating force, and jack relaxes owing to thermal expansion causes steel wire when heat treatment is finalized the design simultaneously; It is even not stressed to cause that jack closing in position discontinuity or stressed reduces, thereby causes heat treatment typing contact engaging and separating force low even unqualified.On the other hand, the stove mode of going into that jack heat treatment is at present adopted is to go into stove to temperature, owing to when going into furnace operating, have bigger heat dissipation, furnace temperature reduces rapidly; Because general heat treatment temperature retention time is to pick up counting when going into stove, and temperature retention time is not enough, heat is not enough again; It is not thorough to cause eliminating internal stress, poor dimensional stability, and elastic stability is poor; Contact engaging and separating force is low, thereby influences heat treatment typing final mass, and 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 deficiency of prior art, improves jack heat treatment typing quality, satisfies electric connector is not less than 2.45N to the jack contact engaging and separating force specification requirement.
Technical scheme of the present invention is to adopt following steps:
1, design special closing in frock closes up to the jack openings position, and it is good to guarantee to close up, and is stressed even.The closing in frock is a sheet material, adopts the 45# steel to make, and opens 91 closing in holes, after machining and through the processing of turning blue, places 20# machine oil and preserves for use.One secondary frock can satisfy the heat treatment of 91 workpiece simultaneously; The closing in frock should guarantee the respond well no gap of closing up, jack openings position, makes each jack stressed evenly again, guarantees that heat treatment typing back 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) cleans jack with gasoline earlier, clean to clean with absolute ethyl alcohol then, dry naturally;
(2) with the jack closing in frock of packing into, the jack oral area is inserted the closing in frock close up, must guarantee that four opening sheets of jack collide, form the annular of a sealing, no gap;
(3) after furnace temperature to be heated reaches 250-320 ℃; The closing in frock is put into Equipment for Heating Processing in the lump together with the jack of packing into heat-treats; Go into stove because of jack and cause temperature to reduce, treat that furnace temperature rises to 250-320 ℃ again and picks up counting, insulation is 3-4 hour under furnace temperature 250-320 ℃ condition; Take out then, 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, qualified products reaches more than 99%.
Beneficial effect of the present invention:
1. utilize the special closing-in frock that jack openings is partly closed up, it is good to close up, stressed even, easy to operate, saves time, and efficient is high, good springiness, and 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 furnace operating is gone in compensation 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 because of doing over again, reprocessing and causes the bigger human and material resources waste of reduction, enhances productivity greatly simultaneously.
