The invention relates to a plug-in connector, substantially consisting of an insulating body and at least one contact element which is mounted directly in the insulating body, wherein the insulating body directly forms the plug-in connector housing of the plug-in connector. The plug-in connector is of particularly simple construction and can therefore be manufactured quickly. In addition, the plug-in connector is of very robust design and suitable for industrial use, in particular in harsh environments.

An assembly comprises a cable and a connector. The cable includes at least four direct current (DC) wires. Each of the DC wires has a first coupling portion at an end thereof. The connector is attached to the cable. The connector comprises a housing and two DC contacts. The housing has two accommodating portions. The two DC contacts are arranged in a horizontal direction. The DC contacts are accommodated in the accommodating portions, respectively. Each of the DC contacts has a contact portion and a second coupling portion. The second coupling portion of each of the DC contacts is connected with the first coupling portions of at least two of the DC wires in the corresponding accommodating portion. The first coupling portions, which are connected with the second coupling portion, are arranged in parallel in the horizontal direction.

The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities. The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within an outer housing and connector assembly. The seal spring compresses and provides adequate spring force against a tab or tabs within the outer housing. The seal spring also functions as an interface seal and an environmental seal during use. The seal spring is, substantially, in its entirety, of a contiguous and continuous single construction. No part or section of the seal spring is made up of welded, soldered, or brazen part or section.

An electrical power connector for an electrical submersible well pump motor has a housing having a bore. A pair of rigid insulators are within the bore of the housing, each of the insulators having a cylindrical outward-facing side that is in contact with an inward-facing side wall of the housing. A resilient elastomer seal is sandwiched between the insulators in sealing engagement with the inward-facing side wall. Passages extend through each of the insulators and the elastomer seal for receiving insulated conductors of a power cable. A spring in abutment with one of the insulators exerts an axial compressive force on the elastomer seal.

An object of the present disclosure is to provide a technique for easily suppressing the intrusion of a resin into a cavity. A wiring member includes: a connector housing provided with a cavity; an electric wire in which one end portion is housed in the cavity and the other end portion extends outward from an opening portion of the cavity; a sealing component that is attached to the connector housing or the electric wire to at least partially close off a gap between the connector housing and the electric wire in the opening portion of the cavity; a resin molded part that covers a portion extending from a rear end portion of the connector housing to a position of an intermediate portion of the electric wire on the other end portion side relative to a portion provided with the sealing component.

A connector housing comprises an inner housing including a rear housing, and a first sub housing and a second sub housing each formed integrally with the rear housing. The first sub housing is sized to accommodate a first cable assembly, and includes a rear end connected to a front side of the rear housing. The second sub housing is sized to accommodate a second cable assembly and a third cable assembly. A rear end of the second sub housing is connected to the front side of the rear housing. The first sub housing and the second sub housing are arranged side by side.

A protection end cover for a sealing ring includes a body having a first end insertable into an insertion hole of a housing of a connector and a second end positioned outside the housing, a first flange on a first outer peripheral surface of the first end of the body, and a second flange on a second outer peripheral surface of the second end of the body. The first flange engages with a blocking part of the housing to prevent the protection end cover from being pulled out of the insertion hole. The second flange abuts against an outer end surface of the housing to limit the protection end cover at a predetermined insertion position.

A connector sealing assembly includes an outer housing defining a plurality of seal mounting portions. A cable seal of the assembly is mounted on a cable seal mounting portion of the plurality of seal mounting portions. The cable seal is sized and located to form a seal between the outer housing and a cable extending into the outer housing. A housing seal of the assembly is mounted on a housing seal mounting portion of the plurality of seal mounting portions. The housing seal is sized and located to form a seal between the outer housing and a mating housing of a mating connector.

A connector housing assembly includes an inner housing, a cable seal and a housing seal. The inner housing defines a plurality of terminal mounting holes for fixedly mounting a plurality of terminals. The cable seal is installed in the inner housing and is adapted to form a seal between the inner housing and a cable extending into the inner housing. The housing seal is sleeved on an outer side of the inner housing and is adapted to form a seal between the inner housing and a mating housing of a mating connector.

A plug connector for providing an electrical connection, having a collective seal with at least one passage opening and at least one electrically conductive plug contact, which is guided through the at least one passage opening of the collective seal. Also disclosed is a template for the passage opening to support the plug contact when the plug contact is guided through the passage opening of the collective seal.
