At least one of first partition wall and second partition wall has a height dimension in a direction perpendicular to both the insertion direction and the alignment direction, the height dimension being smaller at least at one end in the alignment direction than at a portion between opposite ends in the alignment direction.

Disclosed are an M-like elastic contact spring and a terminated adaptor connector. The M-like elastic contact spring comprises two contact portions at two ends and a connecting portion connected between the two contact portions, the contact portions are arc-shaped, the connecting portion is U-shaped, the contact portions are in arc transitional connection with the connecting portion, and the connecting portion and the contact portions form an M structure together. When the contact portions are in contact with the adaptor connector and stressed during usage, the M-like elastic contact spring at least has the following deformable parts: a bent part of the U-shaped connecting portion, transitional parts of the contact portions and the connecting portion, and the parts, close to the connecting portion, of the contact portions; thus, the bending stress of the contact spring under stress can be greatly dispersed, and the fatigue of the contact spring is relieved, and the problem that the contact spring is easily damaged by fatigue is solved.

An electrical connector that has a housing with a mating interface end section, an opposite cable termination end section, and an inner support member. A core is slidably coupled to the inner support member of the housing and includes a receiving end and a spring engagement end. A spring member is received inside of the housing and behind the core for abutment with the spring engagement end of the core. An interposer may be received in the receiving end of the core and remote from the spring member. The core is axially slidable with respect to the inner support member along a longitudinal axis of the housing between an unmated position, in which the spring member pushes the core outwardly away from the cable termination end of the housing, and a mated position, in which the core pushes inwardly against the spring member.

An electrical connector includes an insulating body having multiple receiving slots, and multiple first terminals and multiple second terminals respectively received in the receiving slots. Each first terminal has a first connecting portion, a first elastic arm bending and upward extending from the first connecting portion, and a first conducting arm bending and extending from the first connecting portion. Each second terminal has a second connecting portion, a second elastic arm bending and extending upward from the second connecting portion, and a second conducting arm bending and extending from the second connecting portion. A bent position between each of the first connecting portions and a corresponding one of the first elastic arms is higher than a bent position between each of the second connecting portions and a corresponding one of the second elastic arms.

The pressure contacting connection type contact has a base portion, a connecting terminal for a mating side contact, and a pressure contacting terminal. The pressure contacting terminal is provided with a base end section opposing an other end side of the base portion, where an extending piece extending from second both side portions of an other side of the base portion is folded such that mutual piece thickness faces are opposed, and a pair of pressure contacting pieces having spring characteristics where, from the base end section, the extending piece extends away from the base portion to the tip portion side such that the piece thickness faces are opposed, and in addition rises obliquely at an opposite side of the protrusion direction connecting terminal, and an open angle portion of the tip side of the pressure contacting pieces in which the central conductor can be inserted from an outer direction.

An electrical connector is used to electrically connect a chip module to a circuit board, and includes a body for upward supporting the chip module. The body is provided with multiple accommodating holes arranged in multiple rows. Each two adjacent rows of the accommodating holes are staggeredly arranged in a front-rear direction. Multiple terminals are respectively accommodated in the accommodating holes correspondingly. Each two adjacent rows of the terminals intersect to form at least one intersection area. Each terminal includes a base, an upper elastic arm formed by extending upward from the base for upward abutting the chip module, and a lower elastic arm formed by extending downward from the base for being downward conductively connected with the circuit board. When the chip module presses the upper elastic arm downward, the upper and lower elastic arms abut each other, the abutting position is located above or below the intersection area.

An electrical connector for electrically connecting a chip module to a circuit board includes: a body, configured to upward support the chip module, where the body is provided with a plurality of accommodating holes; and multiple terminals, respectively accommodated in the accommodating holes correspondingly. Each of the terminals includes a flat plate portion along a vertical direction and a connecting portion connected to the flat plate portion. An elastic arm is formed by bending and extending from at least one end of the connecting portion so as to abut the chip module or the circuit board. When the chip module presses the terminal downward, a side edge of the elastic arm abuts the flat plate portion. The structure of an elastic arm can be simplified to reduce the processing difficulty thereof.

A connector having an insertion part into which a connection target is inserted; a plurality of first grooves provided inside insertion part so as to align along an alignment direction being perpendicular to the insertion direction of the connection target, first contact parts being respectively disposed in first grooves; a plurality of second grooves provided inside insertion part so as to oppose to first grooves, second contact parts being respectively disposed in second grooves; first partition wall partitioning adjacent first contact parts; and second partition wall partitioning adjacent second contact parts.
