【摘要】：籠式彈簧連接器作為一種新型的電源連接器,連接方式有很多優(yōu)點。首先,使用過程中它不需要重新檢查或擰緊,可以有效的避免因擾動溫度循環(huán)、絞線斷裂等造成的接觸點松動。其次,籠式彈簧的固有可靠性可以減少停機時間和用戶請求維修的次數(shù)。再次,它的夾持系統(tǒng)接線方式非常簡單、有效,大大節(jié)省了原料消耗。 鑒于彈簧式連接器的優(yōu)點及好材料的昂貴價格,如何選取合適的結(jié)構(gòu)尺寸使彈簧在滿足鎖線力要求的同時不發(fā)生塑性變形,以結(jié)構(gòu)調(diào)整代替材料更換后,降低產(chǎn)品生產(chǎn)成本并使連接器能夠正常工作,即可以發(fā)揮其優(yōu)良性能是彈簧設(shè)計的關(guān)鍵。本文以新一代沖制接觸件電源連接器,SJ0l8兩芯快鎖插頭的彈簧片為研究對象。通過應(yīng)用應(yīng)力、應(yīng)變的力學(xué)知識進行計算,對彈簧結(jié)構(gòu)進行力學(xué)理論分析；利用ABAQUS有限元分析軟件仿真,建立仿真模型,通過對仿真結(jié)果分析,共同找出設(shè)計的薄弱環(huán)節(jié)。最后,使用插拔力試驗機對計算和仿真的結(jié)果進行驗證,總結(jié)出結(jié)構(gòu)、材料參數(shù)等對彈簧性能的影響。 文章總結(jié)出影響彈簧性能的關(guān)鍵參數(shù)為材料的楊氏模量、彈簧端子的寬度、長度、厚度、彎曲處的曲率半徑等。得出即使在材料參數(shù)不佳的情況下,也可以通過調(diào)整結(jié)構(gòu)參數(shù)使彈簧獲得同樣的工作性能,滿足使用要求,給出設(shè)計指導(dǎo)。
[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.
