The presence of a plug connector with a port is detected through a detection circuit activated by a port shutter. Transitioning the port shutter between the closed (i.e., blocking the port) position and the open position actuates and deactuates the detection circuit.

An electrical connector includes: an insulative housing defining an upper face and a lower face and having a plurality of passageways running though the upper and lower face; and a plurality of contacts secured in the plurality of passageways of the insulative housing. Each of the plurality of contacts includes a base part, an upper arm extending from the base part, and a first part and a second part bent from opposite sides of the base part, a first limb bent from the first part and a second limb bent from the second part plate body. The first limb and the second limb are located staggered in an upper and lower direction, thereby the base part, the first and second part and the first and second limbs together form a tubular structure.

A gas sensor (1) including: a sensor element (21) having an electrode pad (24); a metal terminal (75) electrically connected to the electrode pad via a contact portion C1; and a separator (91) retaining the metal terminal, wherein the metal terminal includes a stopper portion (75p) extending in a direction crossing the axial-line 0 direction, and where, in a pair of one of an electrode pad (241) and one of a metal terminal (751) connected thereto, as seen along a widthwise direction of the sensor element, an end of the one electrode pad that is closest to one inner surface 91si of the separator is defined as a pad end, a distance between the pad end and the contact portion is defined as DA, and a distance between the one inner surface of the separator and a distal end of the stopper portion is defined as DB, DA>DB is satisfied.

A circuit apparatus includes: a stacked body; and a plurality of terminals. The stacked body includes a plurality of layers. A plurality of holes that extend through the plurality of layers are formed in the stacked body. Each of the plurality of layers includes a connection member that is formed of a conductor. The connection member includes: a plurality of connection portions that are provided at positions corresponding to the plurality of holes; and a joining portion that connects the plurality of connection portions to each other. The plurality of terminals include a plurality of types of terminals that correspond to the plurality of layers. Each of the plurality of types of terminals can be selectively connected to the connection portion of a corresponding one of the plurality of layers by being inserted into a predetermined one of the plurality of holes.

A PCIe SAS direct link connector includes a cable end and a back board; the cable end fixed on the back board and including a direct link female head, a high-speed line, and a 15pin plug terminal; the back board including a primary and a secondary cavity position; the direct link female head connected with the high-speed line; the 15pin plug terminal being an asymmetric bow shape and having a short and a long side, a first contact point disposed on the short side, and a second contact point disposed on the long side; the 15pin plug terminal connected with the high-speed line; when the 15pin plug terminal is combined with a server board end connector, the first contact point and the second contact point contact a terminal of the server board end connector, respectively, simplifying the connection structure and improving heat dissipation.

An electrical connector is used to be electrically connected to a chip module, and includes a body provided with at least one accommodating groove. The body has a supporting block protrudingly provided upward at one side of the accommodating groove, and the supporting block is configured to upward support the chip module. At least one terminal is correspondingly accommodated in the at least one accommodating groove. The terminal includes: a first base accommodated in the accommodating groove; an elastic arm formed by bending and extending forward from the first base and located at one side of the supporting block to be electrically connected to the chip module; and a through slot running vertically through the elastic arm. The supporting block has a rear end. The first base is located behind the rear end. The through slot extends forward and does not pass beyond the rear end.

A tactical rail for a firearm includes a rail body having a receiver end and a muzzle end and a non-contact optical connection arranged at an end of the rail body and configured to interface with a corresponding non-contact optical interface. A low speed data bus segment extends between the receiver end and the muzzle end of the rail body. A high speed data spoke is connected to the non-contact optical connection for high speed data communication with a high speed data accessory through the non-contact optical connection and the corresponding non-contact optical interface. Tactical rail systems and firearm assemblies having tactical rails are also described.

A plurality of laterally extending modules aligned longitudinally orthogonal to the lateral direction with terminals attached to each module housing, each terminal including a longitudinally extended main body held in the module housing, a contact arm extending upward or downward from the main body, the contact arm including a contact portion contacting a counter terminal, a first bent portion connected to the main body and bent upward or downward, and a second bent portion formed between the contact portion and the first bent portion and bent in a direction opposite to the first bent portion.

The present disclosure provides an electrical connector and a device for testing conduction which relate to the field of testing devices. By providing a first contact end having a planar structure, the contact area between the electrical connector and a testing substrate is increased, and a large current can be conducted and damage to the product and device is avoided. A second contact end is a point or linear structure, and when poor contact is caused due to the uneven testing substrate or oxidization of the testing substrate, effective contact and electrical connection with the testing substrate can be achieved, to improve the effectiveness of an electrical connection.
