Electric connector and its electric element

一种改进了的电连接器及其电器元件，用来在电部件的接触部与电路衬底的接触部之间形成电连，同时还提供了构造这种电连接器的方法。此电连接器包括：连接器体；一批电接点，设在此连接体上且布置成能与电部件的接触部分匹配；一批细长的电导线，或称之为终端尾端，设于连接体上并布置成与电路衬底形成电连。这些细长的导线与对应的电接点电连。衬底接点例如焊球则经对焊连接到各细长导线的端部，使得在细长导线与电路衬底的接触部之间能有选择地形成电连。本发明改进了电连接器设备以及伴随的电连接器构造技术。 An electrical connector (1) for use with a circuit substrate has a spacer member (10) and a plurality of elongated conductors (8). The conductors are fitted into passages (25) on the spacer member (10). A tail end of each conductor terminates in a well (11) on a surface of the spacer member that facilitates the attachment of the electrical connector to the substrate. The passages in the spacer member hold the conductor tail ends in alignment while providing a clearance around the conductors to accommodate the effects of thermal expansion and contraction. Solder paste (19) from the well (11) with or without a preformed solder ball (12) is coalesced into a spherical shaped conductive body at least partially extending outside said well for connection between the conductors and the circuit substrate. A spherical shaped conductor body is fused to the end of the conductors (8)
