斜圈彈簧是圓形饒線的彈簧,其饒線線圈是橢圓的,傾斜的,當遭到緊縮時,每個線圈將產生單獨變形,無論線圈的哪壹局部產生變形,整個彈簧都將停止反響,從而完成在每個接觸點上的負載分歧.
The inclined coil spring is a circular spring with an elliptical and inclined coil. When it is tightened, each coil will deform independently. Whatever part of the coil deforms, the whole spring will stop responding, thus completing the load divergence at each contact point.
關於銜接件來說,彈簧的末端將焊接起來從而組成壹個完好的環,關於每種規範線圈尺寸上的詳細的插入或是拔出的應力請求,在插座和插頭的設計中,彈簧可放入凹槽內.當凸槽插入凹槽內,彈簧的斜圈彈簧在持續的彈簧應力作用下變形,並將形成抵禦力直到線圈停止配對的槽.此時,彈簧線圈的負載和槽的設計將產生出持續的彈簧應力,這樣壹來,則需求壹個相應的拔出力來斷開這2個部件,在微型銜接件的卡扣上,徑向的斜圈彈簧具有2個關鍵的作用,並可以減少系統中元件的數量.
For the connector, the end of the spring will be welded together to form a complete ring. For the detailed insertion or pull-out stress requirements of each specification coil size, in the design of sockets and plugs, the spring can be placed in the groove. When the groove is inserted into the groove, the inclined coil spring of the spring will deform under the continuous spring stress and will form resistance force until the coil stops. At this time, the load of the spring coil and the design of the groove will produce a continuous spring stress. Thus, a corresponding pull-out force is required to disconnect the two components. On the clamp of the micro-connector, the radial inclined coil spring has two key roles and can reduce the number of components in the system.
斜圈彈簧提供雙重功用,可作為機械接頭運用,也可堅持外螺紋接頭和內螺紋接頭之間的電路,從而使RF幹擾減少到小,用於電子的互連設計較為復雜.裝置簡單的緊湊型設計為軍事,工業,商業應用的互連設計提供了新的考驗.電路的速度在增加,而電子元件的尺寸在減少.因而,銜接件需求以更高的速度在更小的空間內處置更多的信號,或是,在更緊湊空間的接點數量更多,銜接件的尺寸也越小,它共同的彈力–變形曲線,寬余的工作範圍–彈簧答應緊縮達35%,相對穩定的彈力減少溫差,公差和其他偏向形成的磨損,每壹個彈簧圈可單獨發揮作用。

Inclined coil springs provide dual functions, can be used as mechanical joints, can also adhere to the circuit between external and internal threaded joints, so that RF interference can be minimized, and the interconnection design for electronics is more complex. The compact design of simple devices provides a new test for interconnection design for military, industrial and commercial applications. The speed of circuits is increasing, while the size of electronic components is decreasing. Therefore, the connector needs to process more signals at a higher speed in a smaller space, or the number of connectors in a more compact space is more, and the size of the connector is smaller. Its common elastic-deformation curve and wide working range are that the spring promises to be compacted up to 35%. The relatively stable elastic force reduces the temperature difference, tolerance and wear caused by other biases. Each spring coil can be separated. Play a role.

應力與應變曲線
Stress and strain curves
由於彈簧觸指構造的特殊性,普通彈簧的剛度考核轉化為對彈簧觸指的拔插力(或應力應變)的考核,該項指標的測試是在模仿工作狀態下停止的:首先對彈簧觸指施加壹個力,然後察看它的變形量,以考核彈簧的“軟”、“硬”水平,該項指標直接關乎到高壓開關在開斷、閉合過程能否順利。測試該項指標需求壹臺測力計和壹套用來模仿彈簧觸指工作狀態的胎具,出於技術失密,消費廠家目前不提供更詳細的檢驗計劃。經過對觸頭系統研討,提出如下三種檢測計劃:
Because of the particularity of spring finger structure, the stiffness test of ordinary spring is transformed into the test of pull-out force (or stress-strain) of spring finger. The test of this index stops under simulated working condition: first, a force is applied to spring finger, and then the deformation is inspected to check the "soft" and "hard" level of spring, which is directly related to high-pressure opening. Whether the switching and closing process can be smooth or not. Testing this indicator requires a dynamometer and a set of moulding tools to imitate the working state of spring finger contact. Due to the lack of technical secrets, consumer manufacturers do not provide more detailed inspection plans at present. After discussing the contact system, three testing plans are proposed as follows:
1.將彈簧觸指從焊接點斷開,壹端固定,另壹端與測力計相連,對測力計施加不同的力,記載每種力狀況下彈簧伸長量,作出應力-應變曲線,進而選定契合我們產品的彈簧觸指;
1. Disconnect the spring finger from the welding point, fix one end and connect the other end with the dynamometer, exert different forces on the dynamometer, record the spring elongation under each force condition, make the stress-strain curve, and then select the most suitable spring finger for our products;
2.模仿彈簧觸指的工作狀態,設計壹套胎具,如下圖,在模仿導體的軸上施加力F,使軸降落同樣高度H,不同剛度的觸頭,需求的力是不同的,從當選出合適我們公司的產品;
2. Imitate the working state of spring finger, design a set of moulds, as follows, apply force F on the axis of imitated conductor, make the axis descend to the same height H, different stiffness contacts, demand force is different, from the selected products of our company;
3.在2匝或3匝上加力,同時記載尺寸H的變化,能夠得到壹系列的力及對應的H,依據丈量結果選出合適我們公司的產品。
3. By adding force on 2 or 3 turns and recording the change of size H, a series of forces and corresponding H can be obtained, and the products most suitable for our company can be selected according to the measurement results.
