A data transmission device includes a reversible pluggable connection port, a memory and a processor. The reversible pluggable connection port includes a plurality of upper pins and a plurality of lower pins arranged oppositely, wherein the plurality of upper pins include a first identification pin, and the plurality of lower pins include a second identification pin. The processor is connected to the reversible pluggable connection port and the memory, and is configured to output data stored in the memory through the reversible pluggable connection port when detecting a specified signal through the first identification pin, and output a data request signal through the reversible pluggable connection port when detecting the specified signal through the second identification pin.

An encoding device is provided that includes a first encoding part and a second encoding part which are attached to a connector insert assembly, wherein the first encoding part is detachably installed in the first connector insert of the connector insert assembly, and wherein the second encoding part is detachably installed in the second connector insert of the connector insert assembly, and wherein the first encoding part includes a first mating part which is located at the front end of the first encoding part in the insertion direction, and wherein the second encoding part includes a second mating part which is located at the front end of the second encoding part in the insertion direction, and wherein the first mating part and the second mating part are arranged such that, when the first connector insert is inserted into the second connector insert, the first mating part and the second mating part can only fit together in a single orientation in order to prevent mismatching between the first connector insert and the second connector insert. A connector insert assembly with such an encoding device is also provided. The encoding device prevents mismatching between the connector inserts and makes it possible for the installation of the connector insert assembly to be simplified.

The invention relates to an alignment module for a plug-in connector for plugging into a rectangular module frame of a modular plug-in connector, said alignment module comprising: a) a substantially rectangular module body, b) from which module body two pins protrude, c) in addition, at least one securing element which is arranged on the module body in order to secure the alignment module for the plug-in connector to the module frame of the modular plug-in connector.

An electrical connector with electromagnetic shielding includes a connector housing containing an insert configured to receive at least one electrical contact. The connector housing includes a connector body with a substantially cylindrical shape having a rear section, a central section and a front section. A ground ring is mounted around the front section of the connector body. A foolproofing section independent of the connector body is mounted at least partly around the front section of the connector body.

An improved poka-yoke device for an electrical connection assembly having a first part (3) and a second part (4) which can be removably coupled via a mechanical link along a main axis (X). The first part (3) having a first poka-yoke member (31) and the second part (4) having a second poka-yoke member (41). The first part (3) having interlocking securing devices for interlockingly securing the first connector (1) to the panel (P) that accommodates it. The second part (4) having first interlocking fixing device that are arranged so as to fix the second part (4) to the second connector (2), The first part (3) and the second part (4) each having second complementary mechanical fixing devices that are intended to interact with one another by interlocking when the first connector (1) and the second connector (2) are coupled.

A socket connector device for mating with a central processing unit having conductive portions is provided. The socket connector device includes a circuit module, a terminal module, and a cover plate. The terminal module is placed on the circuit module. The terminal module includes a terminal block. The terminal module includes a terminal block, multiple rows of terminals integrally formed with the terminal block, and a support housing protecting the terminal block. Each terminal includes a first contact end and a second contact end corresponding to each other. The second contact end protrudes from the support housing. Each first contact end electrically contacts one conductive portion, and each second contact end electrically contacts the circuit module. The cover plate is rotatably assembled on the terminal module, so that the conductive portions of the central processing unit electrically contact or do not contact the terminals of the terminal block.

A user configurable keyable guide module having a housing with one or more keying guide pin receiving openings which extend from a mating face of the housing toward a rear face of the housing. First programmable keying surfaces are provided proximate the one or more keying guide pin receiving openings. One or more keying guide pins are configured to be positioned in the one or more keying guide pin receiving openings. The one or more keying guide pins have second programmable keying surfaces. A user selects the position of the first programmable keying surfaces and the second programmable keying surfaces.
