Description

ELECTRIC CONNECTOR
Technical Field
This invention relates to an electric connector.
Background Art
Several electric connectors are known and are generally used to connect two or more electric cables.
The connectors of known type generally comprise a tail member adapted to house the electric cable and a head member that can be coupled to the tail member and provided with at least one connector element to which the electric cable must be connected in order to connect the latter to a connecting element.
In particular, the connecting element is generally another electric connector of the type complementary to the first one, so as to achieve a coupling of the male- female type between the two connectors, for example of the plug and socket type.
The tail member generally comprises a cable gland assembly adapted to prevent the cable from being pulled out of the connector and the head member comprises blocking means adapted to electrically connect the cable to the connector element.
In particular, the electric connectors of this type comprise an elastically deformable element to open and close a cable blocking point defined between the connector element and the elastically deformable element itself.
More in detail, this type of connector provides for an opening/closing procedure of the blocking point which is carried out by a specialized operator, who acts on the elastically deformable element by means of a special tool, such as e.g. a screwdriver, or by means of the pressure of the elastically deformable element by means of the cable itself, which is forced inside the blocking point.
This procedure, however, is not particularly practical and requires the operator to apply a significant force to the elastically deformable element that can deteriorate both the elastically deformable element and the cable itself.
To overcome these drawbacks, the blocking means of the electric connectors are provided with an actuation lever mounted on the head member or on the tail member and adapted to act on the elastically deformable element to open and close the blocking point.
This way, the actuation lever allows electrically connecting the cable to a corresponding connector element in a simple and easy manner without the need for tools and without the need to force the cable inside the blocking point.
This type of electric connector, however, is not free of drawbacks related to the mounting of the blocking means.
In fact, the electric connectors of this type comprise a plurality of recesses and grooves which are separate from each other and made on different portions of the tail member and/or of the head member so as to allow the mounting of all the components of the blocking means.
The connector element is generally assembled inside a first recess and the actuation lever is housed inside a second recess made substantially orthogonal to the first one.
In addition, the actuation lever very frequently has to be moved inside the second recess along several different directions of movement in order to open and close the blocking point.
For these reasons, the connectors of this type are particularly complicated to mount and make the assembly operations of the blocking means long and complicated.
Description of the Invention
The main aim of the present invention is to devise an electric connector that allows assembling the blocking means in a simple and fast manner.
Another object of the present invention is to devise an electric connector that allows overcoming the aforementioned drawbacks of the prior art in a simple, rational, easy, effective to use and cost effective solution.
The aforementioned objects are achieved by the present electric connector having the characteristics of claim 1.

In particular, an actuation lever 6, a connector element 29, 30 and an elastically deformable element 5 are shown for simplicity in some illustrations in order to make it easier to understand the view of the illustrations themselves. Advantageously, the assembly means comprise:
at least one guiding groove 22 formed inside the housing 11 a, l lb substantially parallel to the direction of assembly B and provided with at least one bottom wall 23;

Furthermore, the connector element 29, 30 is fastened to the inside of the housing l la, l lb and abuts against the first and the second abutment element 27, 28 in the mounting configuration. In particular, the housing 11 a, l lb comprises at least a first housing stretch l la and at least a second housing stretch l lb communicating with each other, and the connector element 29, 30 comprises at least one connecting portion 29 having a shape substantially complementary with respect to the second housing stretch 1 lb and inserted inside the latter, and at least one coupling portion 30 to the elastically deformable element 5 having a shape substantially complementary with respect to the first housing stretch l la and arranged inside the latter, abutting against the first and the second abutment element 27, 28, the first housing stretch l la having a cross section substantially larger than that of the second housing stretch l lb.
According to the embodiments shown in the illustrations, the grooves 22 are formed inside the first housing stretch l la.
In addition, the first abutment element 27 is a wall substantially orthogonal to the direction of assembly B and defines the narrowing of width between the first and the second housing stretch l lb.
The second abutment element 28, on the other hand, is a protruding stretch made on the coupling face 41 of the covering body 12 and adapted to abut against the coupling portion 30.
According to the embodiments shown in the illustrations, the housing l la, l lb is open at the top at the opening 21.
In fact, the first housing stretch l la substantially has a transverse“U”-shaped section.
The second housing stretch 1 lb, on the other hand, has a substantially circular transverse section.
Advantageously, the coupling portion 30 comprises a substantially flat abutment wall 31, substantially rectangular in shape and positioned substantially orthogonal to the direction of assembly B.
In particular, the connecting portion 29 is substantially cylindrical in shape and is substantially associated with the center of the abutment wall 31 substantially orthogonal to the latter, as shown in Figure 6.
Advantageously, the elastically deformable element 5 comprises: at least one base stretch 32 having a substantially elongated shape;
at least one blocking stretch 44 having a substantially elongated shape and arranged substantially opposite to the base stretch 32;
at least one junction stretch 33 between the base stretch 32 and the blocking stretch 44 having a substantially curved shape and interposed between the base stretch 32 and the blocking stretch 44.
Advantageously, the elastically deformable element 5 is a sheet- shaped body made of an electrically conductive material, substantially rectangular in shape and shaped so as to define the base stretch 32, the blocking stretch 44 and the junction stretch 33.
In addition, the elastically deformable element 5 is coupled to the coupling portion 30 of the connector element 29, 30.
In particular, the coupling portion 30 comprises at least one pair of coupling stretches 34 arranged inside the first housing stretch l la substantially parallel and opposite to each other, and the elastically deformable element 5 is interposed between the coupling stretches 34.
Furthermore, the base stretch 32 is arranged in support with one of the coupling stretches 34 and the blocking stretch 44 is arranged stopped to abut against the other of the coupling stretches 34 to define the blocking point.
Advantageously, the coupling stretches 34 are straight stretches of a substantially flat shape, associated with the abutment wall 31 and defining with the latter a housing volume of the elastically deformable element 5.
According to the embodiments shown in the illustrations, the blocking stretch 44 is positioned substantially transverse with respect to the base stretch 32.
This way, when the elastically deformable element 5 is positioned inside the housing volume, the blocking stretch 44 is positioned substantially inclined starting from the junction stretch 33 as far as abutting against the coupling stretch 34.
In other words, contrary to what happens with the base stretch 32 which completely faces the other coupling stretch 34, only one portion of the blocking stretch 44 is in contact with the coupling stretch 34. In addition, the elastically deformable element 5 is positioned inside the coupling volume with the junction stretch 33 substantially opposite to the abutment wall 31, i.e., the blocking stretch 44 is folded on the base stretch 32 substantially towards the inside of the housing volume, as shown in Figure 5. The coupling portion 30 conveniently comprises at least one intermediate stretch 35 arranged substantially opposite and parallel to the coupling stretches 34 and defining with one of these a slot 36 adapted to receive the base stretch 32.

In addition, the elastically deformable element 5 comprises at least one pair of side stretches 40 arranged substantially parallel and opposite to each other and associated substantially orthogonal to the base stretch 32, abutting laterally the intermediate stretch 35.
Advantageously, the intermediate stretch 35 is associated with the abutment wall 31 and is arranged at a distance from one of the coupling stretches 34 to define the slot 36.
According to the embodiments shown in the illustrations, the blocking means 5, 6 comprise at least one shaped profile 37 made on the actuation lever 6 in the proximity of the pin 25 and arranged in contact with the blocking stretch 44, in the first work configuration the actuation lever 6 being rotated around the axis of rotation A in a direction of rotation for charging the elastically deformable element 5 and the shaped profile 37 pressing on the blocking stretch 44 and moving it away from the coupling stretch 34 to open the blocking point, and in the second work configuration the actuation lever 6 being rotated around the axis of rotation A in a direction of rotation for releasing the charge of the elastically deformable element 5 and the shaped profile 37 being moved away from the blocking stretch 44 which comes close to the coupling stretch 34 to block the cable 3 at the blocking point.
In particular, the blocking means 5, 6 comprise a pair of shaped profiles 37 acting on a lateral side of the blocking stretch 44 respectively. In addition, the actuation lever 6 is positioned substantially transverse to the direction of assembly when it is in the first work configuration and is positioned substantially parallel to the direction of assembly B to occupy the opening 21 when it is in the second work configuration.
A further embodiment of the connector 1 is shown in Figure 7, in which the blocking means 5, 6 comprise at least one protrusion 38 for anchoring the elastically deformable element 5 to the connector element 29, 30 formed on one of the base stretch 32 and the coupling stretch 34 and at least one hole 39 formed on the other of the base stretch 32 and the coupling stretch 34 and adapted to accommodate the protrusion 38 so as to fasten the elastically deformable element 5 to the coupling portion 30.
In particular, in this embodiment, the coupling portion 30 is without the intermediate stretch 35 and the elastically deformable element 5 is without the side stretches 40.
In fact, the coupling between the elastically deformable element 5 and the coupling portion 30 is made by means of the protrusion 38 inserted inside the hole 39.
In particular, the protrusion 38 is an inclined stretch formed on the base stretch 32 and folded towards the latter substantially towards the outside of the housing volume.
This way, the elastically deformable element 5 opposes the traction towards the outside of the housing volume by means of the protrusion 38, which abuts against the side walls of the hole 39.
Alternative embodiments of the connector 1 cannot however be ruled out, wherein the elastically deformable element 5 comprises both the protrusion 38 and the side stretches 40 and wherein the coupling portion 30 comprises both the intermediate stretch 35 and the hole 39.
It has in practice been found that the described invention achieves the intended objects.
In particular, it should be underlined that the use of the assembly means provided with a housing capable of accommodating the contact element, the elastically deformable element and the actuation lever longitudinally along the same axis of assembly significantly simplifies the assembly of the blocking means.
