Abstract

本发明涉及一种具有基部壳体(3)、预模制壳体(5)、和重叠模制的壳体(7)的电连接器组件，其中该重叠模制的壳体具有应变消除延伸部。

Description

具有重叠模制壳体的电连接器
技术领域
本发明涉及电连接器壳体结构。
背景技术
现有技术的电连接器的缺陷在于，金属外连接器壳体制成后带有应变消除部分和电缆接线端，该接线端通过使用金属构件固定到刚性的金属壳体上。该金属构件通常包括带有螺纹的适配器和螺母、垫片、以及橡胶垫圈。紧固该螺母以便围绕电缆压缩该垫圈并提供应变消除部分。这需要许多部件并且导致较重的外壳。此外，螺母可能被旋松，这使得外界的致污物进入并使得电缆从壳体中拉出。
发明内容
为了克服上述现有技术的缺陷，本发明提供了一种包括基部壳体的电连接器，在该基部壳体上用塑料材料重叠模制以便形成重叠模制的壳体。优选的是，该基部壳体由金属制成，并且围绕该基部壳体使用弹性塑料材料铸塑从而进行重叠模制，该弹性塑料材料起到密封作用并提供应变消除部分。预模制壳体优选地在该重叠模制的壳体形成之前施加到该基部壳体的一部分上。
本发明的其它特征包括：电缆应变消除接头防止对插头线连接的损坏；使用特殊结构材料(例如压铸金属和塑料)，以便耐受化学环境和高/低温环境；以及以声音和/或触觉方式确认锁闩接合。
通过参照附图并结合以下对本发明的详细描述以及后附的权利要求，本发明的这些和其它的目的、优点、和特征将明显呈现出来，可更清晰地理解本发明的本质。
附图说明
图1是依据本发明的电连接器电缆组件的透视图；
图2是本发明的电连接器的基部壳体的透视图；
图3是基部壳体和形成在其上的预模制壳体的透视图；和
图4是沿图3所示的线IV-IV截取的局部截面图。
具体实施方式
图1示出了本发明的电连接器。该电连接器1包括三个主体部分、基部壳体3、模制在基部壳体的后部上的预模制壳体5(见图3)、以及重叠模制的壳体7，该重叠模制的壳体在该预模制壳体之上模制，以下将详细描述。
重叠模制的壳体7优选地由具有弹性或回弹性的塑料材料模制成，例如热塑性弹性体材料，但是也可使用例如为热固性材料的硬化材料。重叠模制的壳体7优选地包括围绕电缆11模制的应变消除延伸部9，电缆11装有导线13，该导线13进入基部壳体3的后部并装接到内连接器21的触点15上。
图2示出了基部壳体3，该基部壳体3包括设置在具有电触点15的通道17中的内连接器21，该电触点装接到导线13上，该导线经过基部壳体3的开放后部从电缆11中进入。基部壳体的后部23包括周边凹槽25和凸缘27，它们有助于预模制壳体按照以下方式进行装接。
图3示出了基部壳体3以及模制在其上的预模制壳体5。预模制壳体5可由用于重叠模制壳体的热塑性或热固性塑料材料中的任何一种材料模制成。为了将预模制壳体5装接到基部壳体3上，将带有装接电缆的基部壳体放置在模具中，并且该预模制壳体模制在其上，以便覆盖基部壳体的后部23、导线13、以及电缆11的一部分，如图3所示。
预模制壳体和重叠模制的壳体优选地通过将塑料材料注塑模制到模具中而制成，以便形成如图1和3所示的结构。
为了有助于预模制壳体装接到基部壳体的后部上，周边凹槽25和凸缘27优选地设置在基部壳体的后部上。如图4所示，形成预模制壳体的材料保持在凹槽25中，以便将该预模制壳体锁定到该基部壳体上。
重叠模制的壳体7随后在预模制壳体和基部壳体3的中心部29之上进行模制，以形成如图1所示的本发明的连接器。重叠模制的壳体7优选地如此模制，即，使得其外表面与基部壳体的暴露前部31的外表面平齐。该重叠模制的壳体的表面可包括有助于抓住该连接器的肋31。
在优选实施例中，基部壳体3的前部31设置有凸沿41。该凸沿41是可选的部件，其优选地铸塑在基部壳体3中。该凸沿包括两个修圆的端部43、加强件45、以及加强延伸部47。与其配合的连接器(未示出)包括两个在摇臂上的具有制动件的锁闩，该锁闩卡在该修圆的端部43上。该锁闩在共同未决的名称为“General Motion Connector”、序列号为No.09/805330、于2001年3月14日提交的申请中进行了描述，该申请的内容在此引入作为参考。修圆的端部43代替了圆柱体形的凸沿销，当锁闩施加较高的力时这种凸沿销容易断裂。
加强件45和修圆的端部43具有相对于该壳体的表面的相同的高度，但是它们本身的高度可以不同。延伸部47的情况也是这样。
尽管在此参照当前确定的优选实施例来描述本发明，但是本领域的普通技术人员应当理解，可在不脱离本发明的精神和范围内进行各种变型和改变，因此本发明的范围仅由后附的权利要求来限定。
