To provide a waterproof cable that is easily manufactured and improves waterproofness. The waterproof cable includes: a first cable; a second cable, an end of which is connected with an end of the first cable; a first resin member that coats a connecting part and is formed by insert-molding; a second resin member that coats the first resin member and is formed by insert-molding; and a third resin member that coats the second resin member and is formed by insert-molding.

A connector manufacturing method includes: a first insertion process of inserting a conductor held by a housing through an annular seal member; a second insertion process of inserting the conductor through an annular portion of a support member; a pushing-in process of pushing the seal member into a gap between an inner circumferential surface of a recess in the housing and the conductor by pressing the seal member using the annular portion; and an engagement process of making the annular portion support the seal member at a predetermined position by engaging the support member and the housing, wherein the predetermined position is a position before a bottom portion of the recess.

An underwater connector half includes a base and at least two electrical connection terminals respectively connected to two electric wires received in at least one cable. The two electrical connection terminals are ring-shaped and coaxial about an axis located along a direction of assembly of a complementary connector half and the base has a side wall that is parallel to the axis and through which passes the cable. An underwater connector including such a connector half is also disclosed.

An electrical connector is provided that includes a first conductor for receiving electrical power. A first seal is coupled to the first conductor for protecting the first conductor. An insulating body is coupled to the first conductor, and includes an electrical terminal that establishes electrical connections between the first conductor and a plurality of electrical terminal pins. A downhole cable is coupled to a first electrical terminal pin of the plurality of electrical terminal pins. The first electrical terminal pin establishes an electrical connection between the electrical terminal and the downhole cable to provide the electric power to the downhole cable. A second seal is coupled to the downhole cable for protecting the electrical connection between the electrical terminal and the downhole cable.

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.

A rubber plug holding device 30 includes a plurality of first clamp members 31 located around a predetermined central line CL so as to form a space 51 inner thereto in which a cylindrical rubber plug 5 is allowed to be located; a first support member 32 supporting the first clamp members 31; and a first actuator 33 driving the first clamp members 31. The plurality of first clamp members 31 include three or more first rubber plug contact portions 31e1, which are on the space 51 inner thereto and are to be in contact with an outer circumferential surface of the rubber plug 5. The first support member 32 supports the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL. The first actuator 33 drives the first clamp members 31 such that the first rubber plug contact portions 31e1 get closer to, or farther from, the central line CL.

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 charging coupler has a grip, an electrical connector and a cable holder. The grip has a front opening and a rear opening on two ends thereof The grip has a first half-tube and a second half-tube connected with each other along a longitudinal direction thereof. The first half-tube has a first latch portion and a groove extending along edges thereof to connect the second half-tube. The second half-tube has a second latch portion and a rib extending along edges thereof to connect the first half-tube. The rib is substantially matched with the groove, and a sealant is filled in a gap between the rib and the groove. The first latch portion is latched with the second latch portion to tighten connection of the first half-tube and the second half-tube. The electrical connector is arranged on the front opening, and the cable holder is arranged on the rear opening.

A connector module, including: a housing, a connector, which is arranged in the housing, at least in part, and which has a longitudinal axis in a connecting direction to a mating connector, wherein an axial outer face of the connector with respect to the longitudinal axis is radially spaced from an opposing axial inner face of the housing, at least in part, and a sealing element, in which the sealing element is arranged in the radial clearance formed between the axial outer face of the connector and the opposing axial inner face of the housing and forms a sealing face with the axial outer face of the connector and the opposing axial inner face of the housing in each case. A related connector and method are also described.
