Slits (42) are formed to be at right angles to the longitudinal direction of the metal plate. The width of slits (42) expands or contracts in response to the housing's expansion or contraction due to temperature, and metal plate (40) adapts and prevents stress from accumulating in the through condenser solder section.

Abstract: The front section (2) of the waterproof plug (1) has an opening (10) of a small diameter, and its rear section (8) has an opening of a large diameter. When the waterproof plug (1) is placed over the wire with its conductor (94) exposed by stripping the insulation (92) from the end of the wire, the small diameter opening (10) and the large diameter opening (12) fit tightly over the conductor (94) and the insulation (92), respectively. A pin contact (40) is attached to the wire tip (96) by crimping, and the waterproof plug (1) is retained between the crimping section (46) of the pin contact (40) and the insulation (92) of the wire (90).

Abstract: An electrical terminal assembly comprising an electrical terminal has an insulation displacement contact having a base portion from which extend a pair of coplanar arms defining a slot for receiving an insulated lead. A restraining flange projecting from the top of each arm at right-angles to its plane terminates in a foot which is received in a well in a housing having a cavity receiving the terminal assembly. The well is dimensioned to allow the foot to move parallel to the plane of the arms but not at the right angles thereto. The arms cannot, therefor, twist about their longitudinal axes under the lead insertion force, but can move in their own planes to accommodate the metal cone of the lead as it is forced into the slot.

Abstract: An electrical connector (2) comprising rows of terminals (6) therein has capacitance filter elements (36,38) bonded to side walls (14,16) thereof. The filter elements are comprised of a thin dielectric film laminated on either side with conductive material, the one side serving as a ground electrode and the other side divided into a plurality of signal electrodes separated by gaps formed by conventional etching process. The filter elements also have connection tabs (48,49) extending from a lower end (50) thereof, each tab connected to a separate electrode (42,44) and electrically connected to corresponding terminals (6) of the connector (2). The invention therefore provides for a readily manufacturable and cost effective filtered connector for filtering unwanted frequency components of a signal to be carried, the filter being mountable to the connector housing in an unobtrusive and compact manner.

Abstract: An electrical connector having an improved seal for sealing a terminal area of the electrical connector. The seal has an engaging surface having a groove extending around the perimeter of the seal, thereby defining a first and second wall. The seal is slidably mounted on a cable, and the cable and seal are inserted in an end of the electrical connector so that a channel is formed by the groove and an inner wall of the electrical connector housing. A sealing material is introduced into the end of the electrical connector until it penetrates the seal between the first wall and the inner wall, thereby causing the channel to become filled with the sealing material. The seal provides a heat sink so that the sealing material solidifies in the channel without penetrating the seal between the second wall and the inner wall, thereby sealing the terminal area of the electrical connector from unwanted moisture.
