摘要： A telephone instrument is designed in the shape of an angle, whereby the upper side has a steeper inclination towards the user. The rear wall is at approximately a right angle to the upper side. The bottom side runs at a specific distance, parallel to the upper side and to the rear wall. Since the distance between the upper side and the bottom side is not very great, i.e. since a maximum of only two printed circuit boards can be accommodated one on top of the other in this space, the bottom side below the upper side has a trough which serves both to accommodate an additional printed circuit board and to provide cable entries. This trough does not extend over the total width of the telephone instrument but is narrower. In order to expand the keyboard, one part of the upper side can be moved in the longitudinal direction, away from the user, so that an additional keyboard or indicator device below it is made available.
摘要翻译：电话乐器被设计成角度的形状，由此上侧朝向使用者倾斜更陡峭。后壁与上侧大致成直角。底面平行于上侧和后壁延伸一定距离。由于上侧和下侧之间的距离不是非常大，即由于在该空间中最多只能容纳两个印刷电路板，所以上侧的下侧可以具有槽，用于容纳另外的印刷电路板并提供电缆入口。该槽不延伸超过电话乐器的总宽度，但较窄。为了扩展键盘，上侧的一部分可以在纵向方向上移动，远离用户，使得其下方的附加键盘或指示器装置可用。

摘要： A terminal of a telephone switchboard installation with one dialing and one service and/or input keyboard and one or more indicator device(s) and a cradle for the hand set. The terminal includes, on the upper side of the terminal a sliding part, which is formed by the upper side which accommodates the keyboards and sometimes includes an indicator device. In one position, the sliding part operationalizes an additional keyboard or indicator device which is located beneath it. This additional keyboard may be designed as a targeted dialing key set, an alpha-numerical input keyboard, etc., and in addition, the keyboard may be replaced with a bank of lamps indicating lines in use.

摘要： A handset for telephones and the like has electro-acoustical capsules for hearing and speaking, mounted between an upper housing shell and a lower housing shell of the handset. Each of the capsules is connected to the handset cord by a pair of leads received in cutting clamp connections arranged on the rear sides of the hearing and speaking capsules, the opposed housing shells having projections pushing the leads into the cutting clamps. Preferably, the leads are mounted on a foil having openings for the cutting clamps and the projections, and also openings for guide pins, whereby the leads are guided into the cutting clamps when the upper and lower housing shells are brought together on the leads.
摘要翻译：用于电话等的手机具有用于听觉和讲话的电声学胶囊，安装在手机的上壳体和下壳体之间。每个胶囊通过一对引线连接到听筒线，该对引线被接收在布置在听力和说话胶囊的后侧上的切割夹紧连接件中，相对的壳体具有将引线推入切割夹具中的突起。优选地，引线安装在具有用于切割夹具和突起的开口的箔片上，以及用于引导销的开口，由此当上壳体壳体和下壳体壳体一起放置在引线上时，引线被引导到切割夹具中。
