【摘要】：笼式弹簧连接器作为一种新型的电源连接器,连接方式有很多优点。首先,使用过程中它不需要重新检查或拧紧,可以有效的避免因扰动温度循环、绞线断裂等造成的接触点松动。其次,笼式弹簧的固有可靠性可以减少停机时间和用户请求维修的次数。再次,它的夹持系统接线方式非常简单、有效,大大节省了原料消耗。鉴于弹簧式连接器的优点及好材料的昂贵价格,如何选取合适的结构尺寸使弹簧在满足锁线力要求的同时不发生塑性变形,以结构调整代替材料更换后,降低产品生产成本并使连接器能够正常工作,即可以发挥其优良性能是弹簧设计的关键。本文以新一代冲制接触件电源连接器,SJ0l8两芯快锁插头的弹簧片为研究对象。通过应用应力、应变的力学知识进行计算,对弹簧结构进行力学理论分析；利用ABAQUS有限元分析软件仿真,建立仿真模型,通过对仿真结果分析,共同找出设计的薄弱环节。最后,使用插拔力试验机对计算和仿真的结果进行验证,总结出结构、材料参数等对弹簧性能的影响。文章总结出影响弹簧性能的关键参数为材料的杨氏模量、弹簧端子的宽度、长度、厚度、弯曲处的曲率半径等。得出即使在材料参数不佳的情况下,也可以通过调整结构参数使弹簧获得同样的工作性能,满足使用要求,给出设计指导。
[Abstract]:As a new type of power connector, cage spring connector has many advantages. First of all, it does not need to re-check or tighten in the process of use, which can effectively avoid the contact point loosening caused by disturbance temperature cycle, strand fracture and so on. Secondly, the inherent reliability of the cage spring can reduce the downtime and the number of user requests for maintenance. Again, its gripping system wiring mode is very simple, effective, and greatly saves the consumption of raw materials. In view of the advantages of spring connectors and the high price of good materials, how to select the appropriate structural dimensions so that the spring can meet the requirements of the locking force without plastic deformation, and replace the material with structural adjustment after replacement, The key of spring design is to reduce the production cost and make the connector work properly. In this paper, the spring plate of the new generation power connector SJ0l8 with two cores and fast locking plug is taken as the research object. By applying the mechanical knowledge of stress and strain, the mechanical theory of spring structure is analyzed, and the simulation model is established by using Abaqus finite element analysis software, and the weak link of the design is found through the analysis of simulation results. Finally, the effect of structure and material parameters on spring performance is summarized by using the test machine to verify the results of calculation and simulation. The key parameters affecting the spring performance are the Young's modulus, the width, length, thickness and curvature radius of the spring terminal. It is concluded that even if the material parameters are not good, the spring can obtain the same working performance by adjusting the structural parameters, which can meet the requirements of application, and give the design guidance.
