Description

一种电连接器插孔热处理工艺 An electrical connector jack Heat Treatment Process

技术领域 FIELD

[0001] 本发明涉及一种电连接器插孔热处理工艺,属于电连接器热处理加工技术领域。 [0001] The present invention relates to an electrical connector socket heat treatment process, the processing belonging to the technical field electrical connector heat treatment. 背景技术 Background technique

[0002] 插孔是无线电控制系统的关键连接部件之一,开口部位开有四个开口槽,要求机加工完成后,通过收口至相碰后进行热处理定型,以消除插孔机械加工产生的内应力,稳定尺寸,获得良好的弹性及弹性稳定性,满足插拔力不小于2. 45N的技术要求。 [0002] The connecting member insertion hole is one of the key radio control system, the openings of four openings open groove, required machining is completed, the heat treatment is performed to the cuff by touching shaped, machined to remove the inner hole generated stress, dimensional stability, good elasticity and elastic stability, meet the technical requirements insertion force of not less than 2. 45N. 现有插孔热处理加工工艺是:先对插孔开口槽部位进行收口,通常采用Φ0. 2mm的低碳钢丝捆扎开口槽部位使得开口处四个开口片相碰,用钢丝捆扎收口时,收口效果不良,开口部位始终存在一定间隙,收口不均勻,另外不同的操作者,捆扎的松紧程度不一样,收口间隙不均勻,造成插孔热处理定型后插拔力低甚至不满足技术条件要求,同时插孔在热处理定型时由于热膨胀而造成钢丝松弛,引起插孔收口部位受力不均勻或者受力减小甚至不受力,从而导致热处理定型插拔力低甚至不合格。 Jack conventional heat treatment process are: first groove portion opening to be shut jack, usually low carbon steel wire tying Φ0 2mm opening groove opening portion such that four openings collide sheet, when the wire tying shut, shut effect. bad, there is always a gap opening portion, shut unevenness, additional different operators, the tightness of the binding is not the same, shut uneven gaps, resulting in low insertion force after the heat treatment finish receptacle does not satisfy the technical requirements even while interposing setting hole during heat treatment due to thermal expansion caused by the slack wire, causing shut receptacle portion or discontinuity unstressed even reduced forces, resulting in a low heat setting even unacceptable insertion force. 另一方面,目前插孔热处理采用的入炉方式是到温入炉,由于在入炉操作时会有较大的热量散失,炉温迅速降低,又由于一般热处理保温时间是从入炉时开始计时,保温时间不足,热量不够,导致消除内应力不彻底,尺寸稳定性差,弹性稳定性差,插拔力低,从而影响热处理定型最终质量,插拔力达不到2. 45N的技术要求。 On the other hand, the present embodiment the furnace is used to heat the jack into the furnace temperature, since there will be greater heat loss during operation of the furnace, the furnace temperature decreases rapidly, and because the heat treatment holding time is generally into the furnace from the start of time, insufficient holding time, the heat is not enough, resulting in not completely eliminate the stress, poor dimensional stability, poor stability elasticity, low insertion force, thus affecting the quality of the final heat setting, the insertion force of less than 2. 45N of the technical requirements.
