Electrical connectors for automatic swimming pool cleaners (APCs) are described. The connectors may be positioned on, at, in, or near bodies of the APCs and configured to be submerged in water of swimming pools. They additionally may be designed to withstand mechanical pulling stresses when their associated electrical cables are pulled by users to remove APCs from the pools. If such a connector is separable, essentially the entirety of the electrical cable may be separated from the APC for purposes of untangling or storing the cable, as examples. The separation additionally may allow for insertion of one or more extension cables as needed or desired.

A cable connector includes an outer housing, an inner housing including a first housing and a second housing assembled with each other, and a cable assembly retained between the first housing and the second housing. The cable assembly includes a pair of terminals, two wires, and a sleeve. The second housing defines a group of first holding portions for holding the wires. The first housing and the second housing each define a group of second holding portions for commonly holding the sleeve.

Various embodiments of the teachings herein include a signal cable connection device comprising: a cable with a sleeve and multiple loose wires extending out from an extremity of the sleeve; a conductive metal ring crimped at the extremity so the ring and the sleeve are fixed to each other, one end of the conductive metal ring having an outward-turned flange, and a shielding wire connected to the conductive metal ring; and a housing with a cable channel defining an outer opening located at an outer side of the housing and an inner opening located at an inner side of the housing, and a threaded hole at an edge of the inner opening. When a screw is screwed into the threaded hole, the outward-turned flange of the conductive metal ring is clamped between a head of the screw and a sidewall of the inner opening.

A receptacle connector with a cable-clamped structure of the invention includes a housing, an electrical module and a cable clamping module. The electrical module is disposed in the housing and includes a circuit board, a plurality of contacting terminals and a plurality of prick type terminals. The circuit board is disposed in the housing. The contacting terminals and the prick type terminals are disposed on the printed circuit board. The cable clamping module includes a first clamping member, a second clamping member and a cable clamper, wherein the first clamping member engages the second clamping member, and the cable clamper is pivoted to the first clamping member. A cable extends through the first clamping member and the second clamping member engaging the first clamping member, the cable clamper presses the cable with the first positioning portion positioned in the second positioning portion of the first clamping portion.

A plug arrangement for use with cables (K) having cable plugs (S) comprises a housing (1) for receiving the cable plug (S), a clamping element (5) encompassing the cable (K) and accommodated in the housing (1), which clamping element (5) clamps, in a compressed state, the cable (K), and a clamping sleeve (3) for establishing a threaded connection with the housing (1). When the threaded connection is tightened, the clamping element (5) is braced in the housing (1) and the cable (K) is clamped in the clamping element (5). The front end of the clamping element (5) facing the cable plug (S) is configured for receiving and positioning the cable plug (S) in a predetermined position at the front end of the clamping element (5) or is provided with at least one stop for the cable plug (S). Thus, when the threaded connection is tightened, the cable plug (S) is also positioned with respect to the housing (1) and the clamping element (5) so as not to rotate and fixed.

The cable assembly includes a first wire assembly. The first wire assembly is connected to a first connector and a second connector. The first connector includes a shell and the shell includes an extension. The extension extends away from the rear of the connector. In one embodiment, the extension is integral with the shell. The extension includes one or more openings. The first wire assembly is bent in a controlled manner at first bend. The first opening in the extension maintains the first wire assembly in the bent position to maintain control of the radius in first bend. The radius is controlled to allow the first wire assembly to fit in a small space.

A printed circuit board plug-in connection is provided for transmitting the highest possible currents between a printed circuit board and an electrical cable, the printed circuit board plug-in connection being manufactured as simply and economically as possible. For this purpose, a plug-in connection having a slotted pin contact is proposed. Said pin contact is arranged in an insulating body and can be inserted directly into a passage contact opening of a printed circuit board in order to establish electrical contact. The insulating body has detent arms, which releasably engage in detent openings of the printed circuit board in a locking manner at the same time. By means of dovetail connections, several insulating bodies can be fastened to each other, i.e., can be cascaded with each other. A strain relief element can also be fastened to an insulating body by means of the dovetail connection in order to provide strain relief for individual conductors of the cable.
