A connector includes an insulative housing having opposite upper and lower surfaces with a plurality of passageways extending therethrough, and a plurality of contacts retained in the corresponding passageways, respectively. Each contact includes a primary part and a secondary part discrete from each other. The primary part includes a first main body with a first spring arm extend upwardly through the upper surface for mating with the CPU, and a first soldering section around the lower surface. The secondary part includes a second main body with a second spring arm contacting the first main body, and a second soldering section around the lower surface. A solder ball is attached to the first soldering section and/or the second soldering section.

A CPU socket has an insulative housing equipped with two groups of contacts of different pitches from each other wherein either each group of contacts are arranged with the corresponding contacting arms extending in opposite directions to counterbalance the imposed/reaction forces itself or the two group of contacts are arranged with the corresponding contacting arms extending in opposite direction to somewhat counterbalance the imposed/reaction force during receiving a CPU therein, and or in a mixed manner, i.e., one group of contact with the corresponding contacting arms in the same direction while the other of contacts with the corresponding contacting arms extending in both opposite directions to achieve the total reaction forces in a substantial balanced manner.

An electrical connector includes an insulative housing with a plurality of passageways extending through opposite upper and lower surfaces of the housing. A plurality of electrical contacts are received within the corresponding passageways, respectively. Each contact includes a first main body and a second main body side by side arranged with each other with a bridge transversely linked therebetween. At least one of the first main body and the second main body includes a retaining barb for retaining contact in the passageway. Two soldering pads are formed on the corresponding bottom ends of the first main body and the second main body, respectively. The two soldering pads intimately confront each other either in a horizontal direction or in a vertical direction, and are joined together via a solder ball located under the two soldering pads.

A connector includes a flat-plate housing made of insulating resin and including a first positioning hole and a second positioning hole, a plurality of contacts held on the housing, and a first hold-down and a second hold-down made of metal and disposed to correspond to a first positioning hole and a second positioning hole, respectively. The housing includes a CPU board opposed surface to be opposed to a CPU board. The first hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding first positioning hole. The second hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding second positioning hole.

An electrical connector includes an insulative housing composed of a plurality of parallel partitions each extending in a longitudinal direction, and plural rows of contact modules each extending in the longitudinal direction and disposed in the housing. Each contact module includes a plurality of contacts integrally formed within an insulator/wafter which extends in a longitudinal direction. In each contact module, each contact includes a main body with opposite contacting arms on upper and lower sections. The contact modules are successively assembled downwardly in the housing by plural assembling poles each of which retainably extends through plural contact modules in the transverse direction and retained in the corresponding positioning grooves formed in the corresponding partitions, respectively.

A lens mounting apparatus includes a base including an opening, wherein a lens including a connection part is inserted and attached, an annular frame including a notch provided on a part of an outer periphery, a socket electrically connected to the connection part of the lens, and a first elastic member provided to urge the socket from the outer periphery toward a center of the annular frame. The annular frame is configured to fix the lens inserted and attached into the base by rotating the annular frame in one direction by a predetermined angle. When the annular frame does not fix the lens, the notch does not face the socket. When the annular frame fixes the lens, the notch faces the socket, and the socket is electrically connected to the connection part of the lens by an urging force of the first elastic member.

An electrical connector including: an insulative housing defining plural passageways and plural contacts disposed in corresponding passageways, the contact having a base extending in a first vertical plane and a resilient contacting arm upwardly and obliquely extending from an upper end of the base, the resilient contacting arm having a bulged contacting section at a free end thereof, a retaining section sidewardly linked to one side edge of the base to retain the contact within the passageway, and a supporting section sidewardly linked to another side edge of the base with an upwardly and obliquely curved abutting section at an upper end thereof, wherein the abutting section is adapted to be outwardly deflected when the contacting arm is downwardly deflected to sidewardly press the abutting section.

A connector includes: a contact including a contact portion connected to a connection terminal by pushing the connection terminal of an external device; a protector protecting the contact portion by covering the contact and including a first opening portion making the contact portion protrude; and a base body accommodating the contact and the protector, and including a second opening portion making the protector protrude; a first waterproof elastic member provided between the contact and the first opening portion and preventing liquid from intruding from a space between the contact and the first opening portion; a second waterproof elastic member provided between the protector and the second opening portion and preventing liquid from intruding from a space between the protector and the second opening portion. The contact portion is movable with respect to the first opening portion. The protector is movable with respect to the second opening portion.

A contact for mounting to a substrate includes: an intermediate portion; an upper contacting portion; a lower securing portion for being fitted into a hole of the substrate, the securing portion having a body and a pair of resilient arms; and a leg extending downward from the lower securing portion. Each resilient arm has a first section connected to the body and a second section angled relative to the first section. The pair of resilient arms form four abutting points, for contacting the hole, including a first abutting point defined at an intersection of the body and the first section of one resilient arm, a second abutting point defined at an intersection of the body and the first section of the other resilient arm, a third and a fourth abutting point defined at a free end of the second section of the two resilient arms respectively.

Examples described herein relate to a system that includes: a first signal pin and a first ground pin adjacent to the first signal pin. In some examples, the first signal pin comprises a first portion, a second portion, and a third portion. In some examples, the first ground pin comprises a first portion, a second portion, and a third portion, the second portion of the first signal pin comprises a vertical mount, the second portion of the first ground pin comprises a vertical mount, and the second portion of the first signal pin and the second portion of the first ground pin are arranged proximate one another.
