- the grip element 118 has the flexible jaws 119 that come from an annular portion 120 and that have a conical portion 119', which is intended to be joined with the conical grooves 117 in the collar of the body.
- the annular portion 120 of the grip element 118 is turned towards, and interacts with, an annular striking surface 121 inside the locking nut 116.
- the grip element 118 is also provided with one or, more preferably, two diametrically opposed tongues 122, 123, which are parallel to its jaws 119 and are intended to be inserted in corresponding indentations 124, 125 provided on the outside of the body 111.
- a first tongue 122 may be in the form of an attachment to the grip element 118, lying halfrvay between two contiguous jaws 119, projecting towards the outside of same.
- the second tongue 123 is in a position halfway between two contiguous jaws 119, but moved outwards in relation to same and extending from the annular portion 120.
- the first tongue 122 is longer than the second tongue 123, and correspondingly, the indentation 124 intended to accommodate it is longer than the indentation 125 provided for the other tongue 123, and the longer tongue protrudes from the opening of the nut 116.
- Two lateral locking teeth 122', 123' are provided on the sides of each tongue
- Two opposing teeth 124', 125' which are turned towards one another, are provided on the sides of each indentation 124, 125, close to the free end of the collar 111', respectively.
- the tongues 122, 123 of the grip element 118 are inserted by force into the respective indentations 124, 125 of the body 111, so that the said element may slide axially in relation to the said body.
- the lateral teeth 122', 123' of the tongues 122, 123 strike against the teeth 124', 125' on the sides of the indentations 124, 125 so as to stop the element proper, thus preventing its detachment from the body 111 of the outlet or plug.
- a toothed crown 127 is provided inside the nut 116, close to its opening, and a stop tooth 128 that is intended to interact with the toothing 127 is provided on the outer face of the longer tongue 122.
- the stop tooth 128 is so as to make possible the unidirectional rotation from left to right of the nut 116 for its screwing onto the threaded collar 111' of the body 111 and, on the other hand, to prevent the opposite rotation of the nut for its unscrewing.
- the nut 116 can be screwed to the bottom for the clamping of the cable through the grip element, but cannot be loosened and be unscrewed uncontrollably due to an unintentional release of the cable.
- a ring seal 129 through which the said cable passes and which guarantees the sealing around same below the grip element, may be mounted inside the body without being affected by the said clamping and unclamping means.
- the body 211 of an electrical outlet or plug is shown only partially in its end part, in which it has a collar 211' with an outer threaded section 215 onto which a locking nut 216 is screwed.
- a seat 217 which has conical grooves 217' in the longitudinal direction, which are narrowed towards the inside of the body, is provided in the body 211.
- a grip element 218 is mounted between the collar 211' and the nut 216 for clamping the electrical cable, which is passed through there centrally and which extends through a seal 229.
- the grip element 218 has flexible jaws 219, which come from an annular portion 220 and which have a conical portion 219' intended to be joined to the conical grooves 217' in the collar of the body.
- the annular portion 220 of the grip element 218 is also turned towards, and interacts with, an annular striking surface 221 inside the nut 216, so that the said element is pushed into the body when the nut is screwed onto the threaded section
- the grip element 218 is provided with two tongues 222 to limit
- the tongues 222 are identical, diametrically opposite, placed between two contiguous jaws, and moved outwards in relation to same. These [tongues] are intended to be inserted and to slide in corresponding indentations 224 provided on the outside of the collar 211' of the body 211, corresponding to two flattened sections 223. Each tongue 222 has two lateral locking teeth 222' while two opposing steps 224' are provided on the sides of each indentation 224, close to the free end of the collar 211'.
- the tongues 222 of the grip element 218 are inserted in the respective indentations 224 of the collar 211' so that the said element may slide axially in relation to the body.
- the lateral teeth 222' of the tongues 222 strike against the steps 224' on the sides of the indentations 224 so as to stop the element proper, thus preventing its detachment from the body 211 of the outlet or plug.
- the locking nut 216 remains joined in the axial direction to the grip element 218 and, through this [grip element], to the body 211 of the outlet or plug.
- the internal edge of the annular striking surface 221 of the nut 216 is provided for being inserted by force into a groove 226, which is present around a protuberance of the grip element lying above the annular portion of same, and this groove may be defined by a continuous collar or one with sections, as shown in the drawings.
- Hie connection then makes possible the rotation of the nut 216 in relation to the grip element 218 for screwing and unscrewing on the threaded section 215 of the collar of the body; however, the nut and grip element are kept joined to one another and, through the tongues 222, to the body of the outlet or plug.
- the outer surface of the nut 216 has a toothing or broaching 227, and the body 211, on one side of the collar 211', in the
- a stop tooth 228 ( Figures 7-9), which is intended to engage with the outer toothing or broaching 227 of the nut 216, is provided on the internal surface of the lug 228.
- the stop tooth 228' of the lug 228 is so as to make possible the unidirectional rotation (from left to right) of the nut for its screwing onto the threaded collar 211' of the body 211 and, on the other hand, to prevent the opposite rotation of the nut for its unscrewing. Therefore, the nut 216 can be screwed to the bottom for clamping the cable through the grip element, but it cannot be loosened and unscrewed in an uncontrolled manner due to an unintentional release of the cable.
