Description

背景技术
目前，一般采用两针脚的FPC连接器与FPC薄膜的两条平行线尾端的扁铜线连接。FPC连接器的两针脚的中心距与FPC薄膜平行线尾端的两扁铜线的中心距一致。但是，每一种FPC连接器两针脚之间的中心距是固定的。这样每一种FPC连接器只能与两扁铜线中心距相同的FPC薄膜平行线连接。当需要连接的FPC薄膜平行线的两扁铜线之间的距离变化时，就必须使用其他规格的FPC连接器，造成FPC连接器无法通用。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。
图1是本公开实施例提供的刺破式端子与FPC薄膜平行线尾端冲压结合前的示意图。图2是图1中刺破式端子与FPC薄膜平行线尾端冲压结合后的示意图。图3是图2中FPC薄膜平行线尾端与刺破式端子冲压结合后与孔座和针座插接的示意图。如图1～图3所示，本公开实施例提供的一种刺破式端子，包括一带刺的金属带1和一后端端子2。金属带1的宽度不大于FPC薄膜平行线尾端的扁铜线3的宽度。金属带1沿其长度方向的一侧垂直向外延伸设有一第一尖刺11和一第二尖刺12。金属带1沿其长度方向的另一侧垂直向外延伸有一第三尖刺13和一第四尖刺14。第一尖刺11、第三尖刺13、第二尖刺 12和第四尖刺14在垂直于金属带1且沿金属带1长度方向设置的投影面上的投影依次等间距设置。虽然在上述实施例中描述的是金属带1沿其长度方向的一侧垂直向外延伸设有两个尖刺，但是本领域的技术人员可以想到形成更多的尖刺，以适应不同的应用场景。
根据本公开的实施例，在将刺破式端子与FPC薄膜平行线尾端冲压连接时，金属带1上的第一尖刺11、第二尖刺12、第三尖刺13、第四尖刺14分别刺破带有加强板4的FPC薄膜平行线尾端的扁铜线3并分别向扁铜线3的相对一侧弯折，并使第一尖刺11、第二尖刺12、第三尖刺13和第四尖刺14的尖点压紧固定到FPC薄膜平行线尾端的加强板4上。这样，实现了刺破式端子与FPC薄膜平行线尾端的连接。由于第一尖刺11、第二尖刺12、第三尖刺13和第四尖刺14刺破了FPC薄膜平行线尾端的扁铜线3，因此第一尖刺11、第二尖刺12、第三尖刺13和第四尖刺14分别在刺破扁铜线3的位置与扁铜线3电连接。
在本公开的实施例中，金属带1的后端与后端端子2的前端固定连接，FPC薄膜平行线与刺破式端子冲压连接后通过后端端子2与外部电路电连接。本实施例中后端端子2与一孔座5插接，孔座5与一针座6插接。在其它实施例中，此冲压带上的两刺破式端子与FPC薄膜平行线尾端的两条扁铜线3冲压连接后，两刺破式端子另一端的后端端子2也可以与导线连接。
图4是本公开实施例提供的冲压带上的刺破式端子的后端端子偏向金属带中心线左侧的立体示意图。图5是本公开实施例提供的冲压带上的刺破式端子的后端端子偏向金属带中心线右侧的立体示意图。图6是图4中冲压带和图5中冲压带叠合后进行冲压前的立体示意图。如图2、图4～图6所示，本公开还提供了一种冲压带，包括一金属材料的定位带7以及若干刺破式端子，若干刺破式端子等间距平行排列且与定位带7垂直固定连接。
如图4～图6所示，定位带7沿其长度方向的两侧对称设有若干等间距且依次交替设置的凸出部71以及定位槽72。凸出部71和定位槽72的宽度相同，且定位带7上与两相邻刺破式端子所对应的位置之间设有至少一个凸出部71和至少一个定位槽72。凸出部71垂直于定位带7表面，且凸出部71与定位槽72的中心距与FPC薄膜平行线尾端的两条扁铜线3的中心距一致。定位带7中间位置沿其长度方向还设有若干等间距的定位孔73，且定位带7上 与两相邻刺破式端子所对应的位置之间至少有两定位孔73的中心距与FPC薄膜平行线尾端的两条扁铜线3的中心距一致。
根据本公开的实施例，当将冲压带叠合起来与FPC薄膜平行线尾端连接时，首先将一条冲压带的凸出部71与另一条冲压带的定位槽72扣合，并使得叠合后的冲压带上的两相邻刺破式端子的金属带1的中心距与FPC薄膜平行线尾端的两条扁铜线3的中心距一致。这样就可以防止在冲压时叠合后的冲压带发生相对移动。而且，由于定位带7上两相邻刺破式端子所对应的位置之间至少有两定位孔73的中心距与FPC薄膜平行线尾端的两条扁铜线3的中心距一致，这样就使得冲压带叠合后的两定位带7上的定位孔73重合，这样叠合后的冲压带就可以直接通过冲床与FPC薄膜平行线尾端刺破式连接，显著提高了刺破式端子的生产效率。
具体地，所述定位带7和刺破式端子为一体冲压成型。
具体地，所述定位带7和刺破式端子的材料为磷青铜、磷铜或黄铜。
具体地，所述定位带7和刺破式端子的厚度均不大于1mm。
图7本公开实施例提供的冲压带上刺破式端子的后端端子中心线与金属带中心线重合的示意图。图8是公开实施例提供的冲压带上刺破式端子的后端端子偏向金属带中心线左侧的示意图。图9是公开实施例提供的冲压带上刺破式端子的后端端子偏向金属带中心线右侧的示意图。另外，图10是图7中的冲压带和图8中的冲压带叠合后进行冲压前的示意图。图11是图7中的冲压带和图9中的冲压带叠合后进行冲压前的示意图。图12是图8中的冲压带和图9中的冲压带叠合后进行冲压前的示意图。
如图2、图4～图12所示，本公开还提供了一种如前所述的冲压带与FPC薄膜平行线尾端连接的方法，当冲压带上的两相邻的金属带1的中心距大于FPC薄膜平行线尾端的两条扁铜线3的中心距时，将至少两条冲压带叠合，并使叠合在一起的冲压带上两相邻的金属带1的中心距等于FPC薄膜平行线尾端的两条扁铜线3的中心距，最后将叠合在一起的两相邻的刺破式端子与FPC薄膜平行线尾端的两条扁铜线3通过冲压工艺刺破式连接。
具体地，当冲压带上两相邻后端端子2的中心距大于FPC薄膜平行线尾端的两条扁铜线3的中心距时，两相邻后端端子2中至少有一后端端子2偏向两相邻金属带1的中心线外侧。
本公开提供的刺破式端子、冲压带及冲压带与FPC薄膜平行线连接的方法，通过金属带1上的第一尖刺11、第二尖刺12、第三尖刺13和第四尖刺14将FPC薄膜平行线尾端的扁铜线3刺穿并压紧固定，第一尖刺11、第二尖刺12、第三尖刺13和第四尖刺14分别在刺破扁铜线3的位置与扁铜线3电连接，从而实现了两个刺破式端子与FPC薄膜平行线尾端的两条扁铜线3的电连接，有效地保证了刺破式端子与FPC薄膜平行线尾端的两条扁铜线3的电连接的可靠性，而且该刺破式端子可以与具有不同中心距的两条扁铜线3的FPC薄膜平行线的尾端连接，适用于不同规格的FPC薄膜平行线。同时将本公开的刺破式端子等间隔设于冲压带上，利用冲床使冲压带上的两相邻的刺破式端子与FPC薄膜平行线尾端的两条扁铜线3刺破式连接，实现了高效和大规模生产的目的。
此外，热敏电阻温度传感器是利用导体或半导体的电阻值随温度变化而变化的原理进行测温的一种温度传感器，其包括有薄膜型热敏电阻和NTC温度传感器等。在一些情况下，薄膜型热敏电阻主要是将裸片型热敏电阻通过金属支架封装在薄膜中，然后将金属支架与热敏电阻的引脚通过锡焊焊接，由于焊锡溶解温度为180℃左右。而温度超过180℃时，热敏电阻的引脚与支架之间的连接就会因为焊锡溶解而脱离，导致温度无法测量，而且这种薄膜型热敏电阻的长度最长一般只有50mm，需要通过导线连接，还要对连接处进行绝缘处理，因此其使用环境及应用范围有较大限制。
针对上述问题，本公开的实施例还提供可一种温度一体式薄膜温度传感器，如图13所示，一体型薄膜温度传感器，包括上层薄膜111和下层薄膜106，上层薄膜111和下层薄膜106之间覆盖有至少两条导线108，导线108之间焊接有NTC热敏电阻107。
本公开第一实施例，如图14和图15所示，一体型薄膜温度传感器的生产设备，包括第一导向轮101，位于第一导向轮101下游的导向槽，位于导向槽前端正上方的用于冲断导线的模具102，位于导向槽下游用于拉取导线的机械手103，分别位于第一导向轮101上下两侧的用于对上层薄膜111和下层薄膜106进行导向的第二导向轮104，位于机械手103下游的热压滚轮105以及位于热压滚轮105下游的分切机；上层薄膜111和下层薄膜106内侧涂有胶水，若干NTC电阻107间隔地焊接于两平行的导线108之间形成一组导线组109，若干组导线组109平行间隔的经第一导向轮101进入导向槽前端，模具 102对导线108冲断，机械手103拉取冲断的导线108沿导向槽至涂有胶水的上层薄膜111和下层薄膜106之间，冲断的导线108夹于涂有胶水的上层薄膜111和下层薄膜106之间，并进入热压滚轮105热压，分切机对热压后的上层薄膜111和下层薄膜106进行分切。
本公开中的一体型薄膜温度传感器至少包含有两层带胶水的上层薄膜111和下层薄膜106，至少两条导线108，导线108之间焊有NTC电阻107。导线108是由压延、打印、化学腐蚀方法而形成的。上层薄膜111和下层薄膜106的厚度小于1mm，上层薄膜111和下层薄膜106材料由聚酰亚胺、PET塑料、芳纶、芳族聚酰胺、聚醚醚酮、聚四氟乙烯、聚碳酸脂、聚乙烯、热塑性聚酯、聚苯乙烯等薄膜材料制成。NTC电阻包括裸片型(贴片型)、二极管型和单端玻封型热敏电阻。具体地，热压滚轮105热压温度为170-250摄氏度。
根据本公开的实施例，一体型薄膜温度传感器的生产方法，包括：步骤1，制作若干导线组，每一导线组由两条平行的导线及间隔焊接于两平行导线之间NTC电阻构成。然后，在步骤2，将薄膜进行冲孔。在步骤3，制作单元模块，将每一导线组于NTC电阻焊接处冲断导线形成若干单元模块。在步骤4，通过热压导轮，将步骤3中的单元模块夹于涂有胶水的两层薄膜之间并进行热压，在具体作业时，控制好冲孔尺寸使得上下两层薄膜合在一起时，将导线一端焊好的NTC热敏电阻完全覆盖，并完全覆盖导线，在导线的尾端露出一面有导线，而另一面薄膜覆盖导线。在步骤5，制作NTC温度传感器，将步骤4中热压后的薄膜温度传感器通过冲压分切，将薄膜温度传感器分离出来。
图16是本公开第二实施例的导线组俯视图。如图16所示，本实施例与第一实施例的区别是：将机械手换成了导向轮，将带有热敏电阻的导线、薄膜送入加热滚轮中，其他相同。
根据上述实施例的生产设备和方法，能够提高生产速度快并且产品的外形一致性好。此外，产品的反应速度一致性好。由于进行自动化生产，操作人员少。此外，对NTC热敏电阻的要求高，不便于小批量生产。上述的传感器体积极小，重量极轻，便于在弯曲或狭小空间使用；尤其是穿戴设备上。
以上所述是本公开的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本公开的保护范围。

  13. 如权利要求12所述的冲压带与FPC薄膜平行线尾端连接的方法，其中，当冲压带上两相邻后端端子的中心距大于FPC薄膜平行线的两条扁铜线中心距时，两相邻后端端子中至少有一后端端子偏向两相邻金属带的中心线外侧。
  14. 一体型薄膜温度传感器的生产设备，包括：
    第一导向轮，位于第一导向轮下游的导向槽；
    模具，位于导向槽前端正上方，用于冲断铜线；
    第二导向轮，位于第一导向轮上下两侧，用于对上层薄膜和下层薄膜进行导向；
    机械手或第三导向轮，位于导向槽下游用于拉取铜线；
    位于机械手或第三导向轮下游的热压滚轮；以及
    位于热压滚轮下游的分切机；
    其中，上层薄膜和下层薄膜的内侧分别涂有胶水，多个NTC电阻间隔地焊接于两平行的铜线之间形成一组铜线组，多组组铜线组平行间隔的经第一导向轮进入导向槽前端，模具对铜线冲断，机械手拉取冲断的铜线沿导向槽至涂有胶水的上层薄膜和下层薄膜之间，冲断的铜线夹于涂有胶水的两绝缘片状层之间并进入热压滚轮热压，分切机对热压后的上层薄膜和下层薄膜进行分切。
  15. 如权利要求14所述的生产设备，其中，所述上层薄膜和下层薄膜的厚度分别小于1mm。
