Definitions
- the present application concerns the field of electrical connectors equipped with a male contact intended to fit into a female contact. It aims at an improved connector and applies in particular to connectors designed to withstand high currents.
- Preserving the quality of the electrical contact between the male and female parts of a connector is, due to losses and heating, all the more critical when a connector is intended to carry high currents.
- the female part which surrounds the male part is then made slightly deformable and the external spring structure ensures the tightening of the female part on the male part of the electrical connector. Since the spring here has no electrical conduction function, it can be optimized in terms of mechanical characteristics. However, tightening tends to generate friction between the contact surfaces during insertion and consequently to damage the latter if it is too great.
- the female contact being equipped with:
- a central element internally defining an axial internal housing to accommodate a male contact, said axial internal housing extending along a longitudinal axis and comprising a so-called “mouth” zone through which the male contact is intended to penetrate, and a so-called “bottom” zone opposite which the male contact is intended to be located in a first so-called “tight” position of the connector,
- a ring arranged around said central element and distinct from said central element, the ring being mounted movable relative to the central element and arranged so that an internal wall of the ring is able to slide against an external region of said element central, said internal wall of the ring delimiting an opening of constricted shape, in particular frustoconical or conical, complementary to a profile of said external region of the central element, said constricted shape having a cross section which gradually decreases that we move parallel to said longitudinal axis from the mouth zone towards the bottom zone.
- constricted shape in particular frustoconical or conical
- an elastic member is arranged between the ring and an external region of the central element.
- the elastic member is typically in the form of at least one spring tending to push the central element.
- the elastic member is typically connected to an end region of the ring.
- the male contact is in a housing part provided with a protruding area having a thread and the female contact in another housing part having an external thread.
- the base of the male contact can be surrounded by an envelope made of insulating material and which has the thread to allow the male contact to be screwed into said housing part.
- the central element of the female contact can be movably mounted in said part of said housing.
- an upper end of the central element of the female contact is located in the second volume and in a released position an upper end of the central element of the female contact extends into the first volume.
- Figures IA and IB illustrate an example of a connector as implemented according to an embodiment of the present invention and in a first so-called “tight” position.
- Figure 3 illustrates an example of implementation of the housing for the female contact of the connector.
- the connector can be dedicated to use in a voltage range, which is high in particular compared to the usual voltages 28VDC and 115VAC commonly used in aeronautics: 500 V and more.
- the conductive rod 33 is inserted into an axial internal housing 121 of a female contact 10 made up of several parts (also shown alone in a schematic and simplified manner in Figure 4).
- the axial housing 121 extends along a longitudinal axis A'A (axis which extends parallel to the axis x of an orthogonal reference [O;x;y;z] given in the figures).
- A'A axis which extends parallel to the axis x of an orthogonal reference [O;x;y;z] given in the figures.
- this central element 12 of the female contact 10 comprises a so-called “mouth” zone 121A through which the male contact 30 is intended to penetrate, and extends to a so-called “bottom” zone 121B delimiting the internal housing and located opposite the mouth zone 121A.
- the male contact 30 is introduced into the axial housing 121 by crossing the mouth zone 121A before arriving at the bottom zone 121B.
- the central element 12 of the female contact 10 may include a cutout on a portion of its sides.
- This cutout can be such that the portion of the central element 12 comprising the cutout is provided with a plurality of fingers 129.
- Each finger 129 also called “branch” having a free end. The free end of each of the fingers is distinct from the respective free ends of the other fingers 129.
- the fingers 129 can each have the shape of a portion of a cylinder of revolution.
- the free end of the fingers 129 is located at the level of the “mouth” zone 121A, while another end, opposite the free end, is attached to a base 128 of the central element 12, this base 128 forming the bottom zone 121B of the axial internal housing.
- the female contact 10 here has the particularity of being equipped with a part or an element separate from the central element 12 in the form of a ring 14 also called “sleeve" which is arranged around the central element 12 and movable relative to the central element 12.
- the ring 14 can move in translation relative to this central element 12, in particular during a phase of insertion of the male contact 30 to result in the so-called “tight” position or during a phase of disinsertion of the male contact 30.
- the ring 14 is here connected to the central element 12 by means of an elastic member 25 which can be in the form of at least one spring.
- the elastic organ can be in particular arranged between an end edge 142 of the ring 14 and an external region of the central element 12.
- the elastic member 25 can be a spring formed for example from type 316 stainless steel.
- the connector is also typically provided with at least one housing 60 for receiving the contacts.
- This housing 60 can be formed of two distinct and separable main parts, a part 40 secured to the female contact 10 and a part 50 secured to the male contact 30.
- the second elastic member Tl is attached to the abutment zone 461 of part 40 of the housing.
- the second elastic member Tl can also be attached to a second end region 144 of the ring 14 opposite that to which the elastic member 25 is attached.
- the housing part 40 has on its internal walls and in the first internal volume 410 a tapping 481 to accommodate a thread 51 made on a peripheral part of the male contact 30, in particular on the envelope 50 arranged around the base 31.
