It is aimed to avoid the abrasion of a contact portion of a terminal fitting. When a harness-side housing (4) is connected to a board-side housing (1), a contact portion (12) of a terminal fitting (3) resiliently contacts a circuit board (2), whereas a body portion (5) of the terminal fitting (3) is pressed against a ceiling wall (19) of a cavity (14). The body portion (5) is formed with a projecting edge (13). When there is a thermal expansion difference in an arrangement direction of the cavities (14) between the circuit board (2) and the harness-side housing (4), the terminal fitting (3) pivots with a resilient abutting part of the contact portion (12) and the circuit board (2) serving as a supporting point.

An electrical connection system having a male terminal and female terminal configured to receive the male terminal. The female terminal has a resilient contact defining a ridge extending vertically from a top surface of the resilient contact and extends longitudinally along the resilient contact. The ridge is configured to provide a contact point between the female terminal and the male terminal. A leading edge of the ridge forms a ramp having an angle that is greater than 0 degrees and less than or equal to 30 degrees relative to the top surface of the resilient contact.

A plug includes a body having a longitudinal axis, a prong extending outward from the body parallel to the longitudinal axis, and a biasing element within the body applying lateral pressure to the prong. A second prong can be provided that extends outward from the body parallel to the first prong, and the biasing element can apply lateral pressure to the second prong. The first prong can be biased toward or away from the second prong, and both can be biased in opposite directions. The biasing element can include a spring, and the spring can be disposed between the first prong and the second prong. Also, the biasing element can cause the prong to angle toward or away from the longitudinal axis. A locking mechanism can be provided to move or inhibit movement of the first prong and the second prong.

An electrical connector comprise an insulating housing, a spring clip disposed in the insulating housing, and control pieces for opening the spring clip. The insulating housing comprises outer wall sections separately corresponding to wire inserting spaces defined inside the insulating housing. Each outer wall section at least partially extends into a gap formed by a corresponding control piece when the control pieces are switched to a closed state. Moving spaces are defined on an outside of two sides of each of the outer wall sections. The control pieces perform an opening operation and a closing operation in the moving spaces. When the control pieces are in an open state, the spring clip is observed along the moving spaces. Along a width direction of the spring clip, the spring clip is at least partially exposed in projections of the moving spaces along an up-down direction of the moving spaces.

The application relates to an electrical connection device (100) including a terminal block (10) adapted for connecting to a lug of an electrical cable. The terminal block (10) comprises a locking sleeve (3) adapted for securing the lug so as to enable translation between the terminal block (10) and the lug. The sleeve (3) comprises a first portion (1) and a second portion (2), as well as a pivot element (13, 14) configured such that the first and second portions (1, 2) pivot relative to one another. The pivot element comprises a pin (14) which is connected to the second portion (2) and engaged with the first portion (1) on the side of the first portion (1) substantially opposite the side of the first portion (1) facing the second portion (2). Advantageously, relative rotational is also allowed. A busbar is preferably connected to the terminal block.

Various embodiments provide a connector system including a plug body and a connector body each having one of studs and jacks with parallel misaligned axes. A deformation of one or more of a plug body, studs, jacks, and a connector body is created when plugging together the misaligned studs and jacks. The deformation creates resultant forces between the studs and jacks for electrical contact. The studs and jacks may be solid metal corrosive-resistant parts, such as titanium, Hastelloy, or Inconel.
