A contact assembly for a connector housing includes an adapter element and a contact element. The adapter element has a sleeve with a lead-through opening extending in an axial direction of the sleeve and with a threaded bore extending perpendicularly to the lead-through opening through the sleeve. The contact element is adapted to be inserted into the lead-through opening and latched to the sleeve. The contact element may exhibit varying types of a cable connection section and/or a contact section. The adapter element is receivable within the connector housing and may accept the contact element regardless of the type of cable connection section and/or contact section.

A connector includes a housing having a plurality of cavities, a seal member having a plurality of seal holes, a rear holder that holds the seal member between the housing and the rear holder, and a terminal fitting that is inserted into the cavity through the seal hole. The seal member includes a main body portion disposed on a side of the rear holder, and a plurality of protrusions protruding forward from the main body portion. Each of the seal holes has a shape penetrating in a front-rear direction from the main body portion to each of the protrusions. A space that allows displacement of the protrusions is provided between the housing and the seal member. The housing is provided with a restriction portion that is disposed between the plurality of the protrusions with a gap interposed therebetween.

Electrical term finals and electrical connector assemblies for electrically conductive structures are described. An example electrical terminal has a terminal head and an electrical contact. The electrical contact extends from the terminal head and has a lengthwise axis and a spring finger contact. The spring finger contact is movable relative to the terminal head and has a cantilever portion and a contact portion. The cantilever portion extends away from the terminal head and away from the lengthwise axis of the electrical contact. The contact portion extends from the cantilever portion.

An electrical connector suited for being assembled to a circuit board is provided. The electrical connector includes an insulating body, a plurality of terminals disposed in the insulating body, a first metallic shell sheathing the insulating body to form an insertion space, a second metallic shell superposed on the first metallic shell, and a metallic plate disposed in the insulating body. The second metallic shell has a rear plate opposite to the rear interface, and is not electrically connected to the circuit board. The metallic plate has at least one bending extending out of the insulating body to abut the rear plate, such that the metallic plate and the second metallic shell are electrically conducted.
