    • The present invention relates to a new PTC device having a configuration with which protrusion of solder paste and/or an excess portion of epoxy resin do not adversely affect a jig. Such PTC device 30 includes a PTC member 32 and leads 34 and 36 electrically connected to both sides of the PTC member. The PTC member includes a PTC element 38 and metal electrodes 40 and 42 placed on both sides of the PTC element respectively, and each lead is electrically connected to the metal electrode via an electrically conductive connection portion 50. At least one of the leads 36 has a concave portion which is defined with a bottom portion 44 located adjacently to the metal electrode of the PTC member and a wall portion 46 surrounding the electrically conductive connection portion which connects the leads to the metal electrode.
    • 本发明涉及一种新的PTC器件,其具有焊膏的突起和/或环氧树脂的过量部分不会对夹具产生不利影响的构造。 这种PTC装置30包括PTC构件32和与PTC构件的两侧电连接的引线34和36。 PTC构件包括分别放置在PTC元件两侧的PTC元件38和金属电极40和42,并且每个引线经由导电连接部分50电连接到金属电极。引线36中的至少一个具有 限定有与PTC构件的金属电极相邻的底部44的凹部,以及围绕将导线连接到金属电极的导电连接部的壁部46。
