摘要： A patch module assembly consists of a two piece frame structure, which provides three parallel jack receptacles entering the frame through one end for receiving patch cord wand. The sides of the frame are closed by printed circuit boards which are electrically connected through plug connectors through the other end wall. The circuit boards support T-Bar.RTM. type switch wafers whose normally closed switches are in series in the various printed circuits between connectors. The printed circuitry also connects spring contacts at one of the wand support receptacles to one side of one of the switches. Another wand support receptacle has spring contacts connected to the opposite side of the switches. A third wand support receptacle has spring contacts connected to either one side or the other of the switches. The contacts of the respective receptacles mate with contacts on an insertable wand, which enable patch connection to other circuits. Placing the wand in the first or second receptacle causes an actuator to disconnect the series switches after which one side or the other of each series switch is connected to some remote circuit. The third receptacle does not disconnect the series switches but makes a connection to the line through each series switch to serve as a voltage monitoring device, or the like. In the first two receptacles, the nose of the wand engages a different cam surface of the same actuation lever, which moves against an actuation plunger of the series switch wafer opening the normally closed contacts. The wand is a split cylindrical structure of hollow form, internal portions of which provide two oppositely directed contact assemblies. The contact assemblies can be preassembled and prewired before assembling the wands. In the assembly of the two halves of the cylindrical wand, insulator bases opposed to each other urge the contacts outwardly through holes along diametrically opposite sides of the wand positioned to engage the respective spring fingers.
摘要翻译：贴片模块组件由两片框架结构组成，其提供通过一端进入框架的三个并联插座，用于接收接插线棒。框架的侧面由印刷电路板封闭，印刷电路板通过插头连接器通过另一端壁电连接。电路板支持T-Bar TM型开关晶片，其常闭开关串联在连接器之间的各种印刷电路中。印刷电路还将一个棒状支撑插座上的弹簧触点连接到一个开关的一侧。另一个支撑支座具有连接到开关相对侧的弹簧触点。第三棒支撑插座具有连接到开关的一侧或另一侧的弹簧触点。相应容座的触点与可插入的魔杖上的触点相配合，使得补片能够连接到其他电路。将魔杖放置在第一或第二插座中，导致致动器断开串联开关，其中每个串联开关的一侧或另一侧连接到一些远程电路。第三插座没有断开串联开关，而是通过每个串联开关连接到线路以用作电压监视装置等。在前两个容器中，魔杖的鼻部接合相同致动杆的不同的凸轮表面，该凸轮表面相对于串联开关晶片的致动柱塞移动，打开常闭触点。棒是中空形式的分裂圆柱形结构，其内部部分提供两个相对定向的接触组件。在组装魔杖之前，触点组件可以预先组装和预接线。在圆柱形棒的两个半部的组装中，彼此相对的绝缘体基座通过沿着棒的沿径向相对的侧面的孔向外推动，从而与相应的弹簧指接合。
