A plug connector module is provided for a modular industrial plug connector, wherein the plug connector module is formed from at least two independent functional units. In order to fit a holding frame with a plug connector module, a first functional unit is first of all combined with at least one second functional unit so as to form a plug connector module, and the plug connector module is then inserted into the holding frame.

An electrical connector includes an insulative housing, a plurality of contacts assembled in the housing, a plurality of cylindrical mating ports located on and forwardly extending from a front face of the housing, and a plurality of LEDs (Light Emitting Diodes) disposed in the housing behind the front face thereof. The mating port includes a majority part and a minority part engaged with each other wherein the majority part has the material same with or similar to that of the housing and is spaced away from the LED while the minority part is essentially translucent or transparent for light transmission/guiding and intimately confronts the LED.

An electrical connector, comprising a connector main body, a cable, a connecting housing, a limiting member, and a housing. The connector main body comprises a plugging side and a connecting side. One end of the cable is electrically connected with the connector main body, while the other end protrudes from the connecting side of the connector main body. The connecting housing is disposed at one side of the connector main body. The cable protrudes from one side of the connecting housing close to the connecting side. The limiting member is disposed at one side of the connecting housing close to the plugging side. The housing is disposed at one side of the connecting housing close to the plugging side. The plugging side of the connector main body is disposed in the housing. The connecting housing is assembled to the housing through the cooperation of the limiting member and the housing.

The present disclosure provide an electrical connector module and a heat dissipation housing. The electrical connector module comprises a heat dissipation housing and a plurality of electrical connectors. The heat dissipation housing comprises a metal housing, a positioning component, a plurality of heat dissipating members, and a plurality of buckling members. The metal housing comprises a housing body, which comprises a disposing surface, an accommodating space, and a plurality of first openings. The plurality of first openings is disposed on the disposing surface and is in communicating with the accommodating space. The positioning component comprises a component body and a plurality of positioning members. The component body is disposed on the disposing surface and comprises a plurality of second openings corresponding to the plurality of first openings respectively. Two opposite side edges of each of the second openings are respectively connected with at least one of the positioning members.

A radio-frequency connector assembly includes a male connector and a female connector, which is plugged and matched with the male connector. The male connector includes a male substrate and a shielding case covering the male substrate. The female connector includes a female substrate and a shielding frame having the female substrate disposed therein. Multiple bumps which are distributed along an inner peripheral wall of the shielding case are disposed on at least one of the inner peripheral wall of the shielding case and an outer peripheral wall of the shielding frame, and a distance between every two adjacent bumps is less than or equal to one quarter wavelength of the operating frequency of the radio-frequency connector assembly. Signals in all directions can be shielded in the connector, effectively improving the shielding effect of the radio-frequency connector and the electrical properties of the radio frequency connector.

A communication system includes a receptacle connector assembly including a receptacle cage and a communication connector having an inner receptacle connector and an outer receptacle connector. The communication system includes a pluggable module received in the receptacle cage to mate with the communication connector. The pluggable module includes a pluggable body defining a module cavity. The pluggable module includes a module circuit board having mating pads at a mating edge of the module circuit board plugged into the inner receptacle connector and connector pads at a mounting location remote from the mating edge. The pluggable module includes a plug connector mounted to the mounting location. The plug connector includes plug contacts extending between a plug mating end and a plug mounting end. The plug mating end is plugged into the outer receptacle connector.
