A header connector includes a header housing having a mating end and a mounting end mounted to a circuit board. The header housing has a cavity at the mating end and a flange forming a seal pocket with a seal. A signal contact is received in a signal contact channel of the header housing having a mounting end having a compliant pin configured to be press-fit into a plated via of the circuit board. A ground shield is received in a ground shield channel of the header housing providing electrical shielding for the signal contact. The ground shield has a compliant pin configured to be press-fit into a plated via of the circuit board.

An electronic device includes a transmission medium and first and second duplex electrical connection plugs. The first duplex electrical connection plug includes: an insulated seat; two terminal sets disposed in the insulated seat; and a metal housing covering the insulated seat and provided with a four-sided primary housing, wherein heights of two contact interface substrates of the second duplex electrical connection plug can be fit with the two spaces of the two connection surfaces of a tongue, and a connection slot of the first duplex electrical connection plug is fit with the tongue. The second duplex electrical connection plug includes: an insulated seat; a metal housing covering the insulated seat; and a fitting portion provided on one end of the insulated seat, wherein heights of two contact interface substrates of the second duplex electrical connection plug can be fit with two spaces of two connection surfaces of another tongue.

In a low-height connector combination, a duplex electrical connection socket includes: an insulation base having a tongue, and a metal housing formed with a connection slot. Heights of spaces of the connection surfaces are smaller than a large space of a standard socket having a minimum height and greater than a small space of the standard socket. A duplex electrical connection plug includes an insulation base, a metal housing and a fitting portion having two contact interface substrates and a fitting space. Heights of the contact interface substrates are smaller than a contact interface substrate of a standard plug having a minimum height and greater than the small space. The fitting portion can be bidirectionally inserted into the connection slot. Each of two fitting gaps of the fitting portion between the contact interface substrates and the connection surfaces of the tongue is smaller than 0.15 mm to form tight fitting.

A circuit interconnecting device includes a circuit connection board and a circuit board which is detachable. The circuit connection board includes an input terminal, an output terminal and an onboard slot member. The input terminal is coupled to the onboard slot member through a first circuit, and the output terminal is coupled to the onboard slot member through a second circuit; and the circuit board is inserted into the onboard slot member to connect the first circuit and the second circuit.

Interconnectors, interconnector assemblies, and methods for supporting components are provided. An interconnector as disclosed connects a supported component to another component or assembly securely and accurately, even where the supported component and the other component have different expansion or contraction characteristics. The interconnector includes a plurality of support elements disposed in an array. Each support element includes a support surface at a free end of the support element. The areas of the support surfaces decrease with distance from a center of the array. In a completed assembly, the free ends of the support elements in the array are joined to the supported component.

A bidirectional electrical connector includes a floating or fixed tongue. One metal plate is deployed without overlap to manufacture upper and lower contact interfaces and a metal tongue. The tongue and the H-shaped limit structure can eliminate the short-circuited problem when the bidirectional electrical connector is docked with a complementary electrical connector. The metal tongue or the structure with the metal reinforcement sheets added into the insulation tongue can optimize the use of the bidirectional electrical connector. A snap structure on a metal housing facilitates smooth docking, and the docked state cannot easily get loose, thereby enhancing the docking stability.

Apparatus are disclosed for vehicle connectors for monitoring connection with trailer connectors. An example connector of a vehicle for coupling a trailer to the vehicle includes a wall defining a cavity to receive a trailer connector, a seal to engage the trailer connector when the cavity receives the trailer connector, and a first trailer-connection sensor disposed in the seal to monitor engagement of the trailer connector with the seal to identify a secure connection with the trailer connector.
