A transmission module assembly comprises a cover and an electrical connector received in the cover. The cover includes a body defining a receiving cavity and a mating section extending forwardly from the body. The connector includes an insulating elongated housing and a number of terminals retained in the housing. Each terminal includes an engaging portion extending forwardly beyond the body into the mating section, a tail portion extending upwardly beyond the housing and a connecting portion retained in the housing. There is a gap between the body and the housing for pouring sealant thereinto. A tuber is defined between the housing and the body, and a pair of stoppers positioned at the body abut forwardly against two lateral sides of the housing in an elongated direction, which can prevent the housing from deforming when temperature changes.

Transmission module assembly

A signal transmission module includes a shell and a connector. The shell includes a box and a mating portion. The connector includes an insulative housing received in the box and a set of contacts. Each contact includes a middle portion, a contacting portion extending into the mating portion and a tail portion. A gap is formed between the insulative housing and the box for sealant being injected. The signal transmission module further includes a horizontal channel located between the insulative housing and the box for the sealant entering into and a vertical channel connecting the horizontal channel.

Signal transmission module with reliable sealing structure

A screw retaining mechanism includes a hollow stud and a nut is matched with the hollow stud. The hollow stud has a plurality of elastic plates extending from a free end thereof and along a peripheral wall thereof. An opening is located between two adjacent elastic plates. An inner wall of the nut has a plurality of tubers protruding in the axial direction to match into the opening. The elastic plate defines a first side face and a second side face opposite to the first side face. Said first side face is used to guide the tubers into the opening and the second side face prevent the tuber fall off from the stud.

Screw retaining mechanism and PV junction box assembled with the screw retaining mechanism

Junction box

A PV (photovoltaic) junction box comprises a case, a lid covering the case and a plurality of terminals received within the case. The case has a bottom wall and defines a positive input port and a negative output port, and each terminal having a planar main body retained to the main body. The terminals comprise a first terminal, a second terminal, a third terminal and a fourth terminal, and the main bodies of the terminals are different.

Background of the invention

An electrical connector () includes an insulative housing and a plurality of contacts () retained in the insulative housing. The insulative housing includes a number of receiving slots () and a number of retaining slots () communicating with each other along a front-to-back direction. Each contact () has a securing portion () engaging with the retaining slot (), a contact portion () extending forwardly into the receiving slot () from the securing portion (), and a tail portion () extending out of the insulative housing from the securing portion (). The retaining slot () defines a first inclined face () at an inner wall thereof. The securing portion () has a second inclined face () corresponding to the first inclined face () and abutting against the first inclined face ().

Electrical connector with improved contact position structure

An electrical connector () includes an insulative housing () having a receiving cavity () for receiving a mating plug and a plurality of passageways (); and a plurality of contacts () retained in the passageways respectively. The contacts define a first contact () which is stationary and having a first contacting portion (), a first soldering portion () and a first base portion () connecting with the first contacting portion and the first soldering portion; and a second contact () which is movable to mate with the first contact to form a switch and having a second base portion () and a second soldering portion () extending downwardly from the second base portion, a second contacting portion () extending upwardly from the second base portion. The first contacting portion extends in a first direction. The second contacting portion extends in a second direction which is not parallel to the first direction.

Electrical connector with improved contacts

An electrical connector includes an insulative housing () having a base portion () with a front face () and a rear face (), and a protection portion () extending backwardly from the rear face (). The protection portion () defines a receiving cavity () opening at a rear end thereof. The base portion () defines a plurality of passageways () extending therethrough and communicating with the receiving cavity (). A plurality of power contacts () are retained on the insulative housing (). Each power contact () has a securing portion () positioned in the passageway (), a columned contact portion () and a bending portion () extending from two ends of the securing portion () respectively. The bending portion () is received in the receiving cavity () for dissipating heat best. A metal shield () has a flat portion () affixed to the front face () and a mating portion () extending forwardly from the flat portion (). The mating portion () defines a D-shape mating hole () for receiving a mating connector.

Electrical connector with improved heat dissipation structure

An audio jack connector () with reliable grounding device includes a dielectric housing () defining an inner receiving space () and a grounding member () mounted on the housing (). The grounding member () includes a base portion () secured on the housing, a mating portion () extending into the inner receiving space (), a terminal portion () for inserting into a print circuit board () and a spring portion () extending beyond the housing for connecting to a metallic panel () of an electrical device. This grounding structure combines inner and outer grounding together by an integrated grounding piece, which enhance the grounding effect.

Audio jack connector with reliable grounding device

A miniature audio jack connector () for electrically connecting a mating plug () includes an arched insulative housing (), a number of conductive contacts () retained in the housing () and a pair of switch contacts () containing a movable contact () and an immovable contact (). The housing defines a top wall (), a plug-insertion hole () and an opening () through the top wall. The movable contact defines an elastic arm () with an emboss () extending into the plug-insertion hole and a mating portion for connecting with the immovable contact. The arm () is movable within the opening (), thereby minimizing the profile of the insulative housing ().
