Abstract: A structural improvement of a liquid level sensor includes a pair of terminals, a body, and a reed switch. Each of the terminals has a clamping end, a guiding and connecting end, an extending portion, and a welding end. The body covers outer sides of extending portions. The pair of terminals are disposed at an interval inside the body. The body has a notch and a counterbore. The reed switch is clamped on the clamping ends and located at the notch. The clamping ends are respectively disposed on two sides of the notch and protrude from the body. The welding ends are exposed in the counterbore. The guiding and connecting ends extend outward from a side of the body. In this way, positioning of a reed switch is more accurate, production efficiency can be improved, and manufacturing and assembly costs can be lowered.

Abstract: A connector assembly has a hollow first connector and a hollow second connector. The first connector has an engaging block. The second connector has an opened connecting end, a guiding groove, a resilient tab cavity, an escaping segment and a resilient tab. The resilient tab cavity is defined in the second connector at a side of the guiding groove opposite to the connecting end and communicates with the guiding groove. The escaping segment is formed on and protrudes from an outer surface of the second connector at a position between the guiding groove and the connecting end of the second connector and is hollow to define an escaping space communicating with the guiding groove. The resilient tab is formed on and protrudes from an inner surface of the resilient tab space and has a free end extending into the guiding groove.

Abstract: An electrical connector assembly (1) includes a first connector (2) and a second connector (3). The first connector includes a first housing (21) and first electrical contacts (22). The second connector includes a second housing (31) and second electrical contacts (32). The first contacts include signal contacts (22A), ground contacts (22B), and shield-joint contacts (22C). The signal contacts are arranged in pairs, with each pair transmitting one set of differential signals. The signal contacts within each pair are separated by an empty passage (214). Adjacent pairs of signal contacts are separated by one ground contact or by one shield-joint contact. The second contacts are configured to correspond to the first contacts, so that the first and second contacts can electrically mate with each other to electrically interconnect the first and second connectors. The wide interval between adjacent signal contacts enables cross talk between adjacent signal contacts to be reduced.

Abstract: An electrical connector of the present invention comprises an insulative housing defining a plurality of contact receiving holes for receiving corresponding contacts. The housing forms a protrusion laterally extending into each contact receiving hole from a bottom of an inner wall thereof. Each contact includes an upper contacting section for engaging with a mating lead pin of a chip, a middle fixing section located below the upper contacting section for having an interferential fit with the housing, and a lower inserting section for being soldered to a printed circuit board. The fixing section has an embossment for engaging with the protrusion of the housing to sealingly separate the lower inserting section from the upper contacting section so that solder and flux is prevented from wicking upward to contaminate the upper contacting section when soldering the lower inserting section to the printed circuit board.
