The invention relates to a connector comprising a mechanism for connecting to and disconnecting from a complementary connector. The invention relates also to a connector assembly comprising such a connector.
Such a connector can be used, for example, for military, aeronautical or aerospace applications, or even medical applications.
Generally, a connector assembly comprising two complementary connectors, namely a male connector and a female connector, is commonly used for a removable electrical connection to an electrical circuit, such as a printed circuit.
Typically, the male connector comprises a plurality of connection spindles arranged in one or more rows. The female connector, for its part, comprises female electrical contacts capable of receiving the male connection spindles and connected to electrical conductors to establish an electrical contact.
Because of the friction forces that exist between the female contacts and the male connection spindles, in order to assist a user in separating the two female and male connectors, it is known practice to provide an ejection mechanism movably mounted on one of the connectors.
According to one known solution, the disconnection mechanism comprises two ejection levers that can be actuated manually, and mounted on the end lateral walls of one of the connectors, such as the male connector.
Such a lever is, for example, formed substantially in an “L” shape. The lever has a first extension protruding from the shell of the connector bearing the disconnection mechanism, such as the male connector, in the rest position, that is to say when the two complementary connectors are connected. The lever has a second extension forming a lever foot and extending into a cavity of the male connector comprising the connection spindles.
When a lever is actuated manually by a rotational movement, the lever foot pushes on the complementary connector, such as the female connector, this complementary connector then being displaced vertically by the foot of the ejector-forming lever in order to separate the female connector from the male connector.
According to this solution, the travel of the lever is limited by a stop on an internal wall of the connector, such as the male connector, bearing the ejection levers.
However, with such a solution, the movement of the lever foot pushing on the complementary connector is rotational, such that the force applied to the complementary connector tilts during the actuation of the lever. The disconnection with such a tilted force cannot be accurate in the plug-in zones of the electrical contacts.
Furthermore, such a disconnection mechanism is not designed to lock the connection between the two connectors in the connection position.
Furthermore, according to this known solution, when the two connectors are coupled, the actuation levers occupy a not-inconsiderable space behind the shell of the connector bearing the ejection mechanism. This bulk of the connector bearing the ejection mechanism does not therefore allow, if the latter is mounted on an electrical circuit board, for the arrangement of other electrical and/or electronic components, such as resistors for example, in this space occupied by the actuation levers.
The aim of the invention is therefore to at least partially mitigate the drawbacks of the prior art, by proposing an alternative connector bearing a mechanism which is ergonomic and allows for both:
To this end, the subject of the invention is a connector that can be connected with a complementary connector on a plugging-in axis to produce an electrical connection, characterized in that it comprises a mechanism for connecting to and disconnecting from the complementary connector comprising:
The mechanism borne by one of the connectors is thus able to be engaged in the complementary connector to lock the mechanical connection between the two connectors so as to secure the electrical connection between the two connectors. The mechanical engagement of the mechanism to the complementary connector works by a simple and natural movement while guaranteeing a reliable connection.
Furthermore, the ejection device makes it possible to push the complementary connector in the direction of plugging-in of the connection spindles borne by one of the connectors into the corresponding electrical contacts borne by the other connector. This makes it possible to avoid damaging the electrical contacts by forcing the connectors in order to separate them. It will therefore be understood that the disconnection works in the alignment of the electrical contacts, notably of the electrical connection spindles, thus avoiding damaging these spindles.
It is thus possible to use parts of simple form, such as pieces or plungers to produce the ejection function. Such pieces can further be easily mounted inside said connector so as to be driven translationally by an associated actuation device.
Thus, a mechanism is produced simply that applies a force always in the plugging-in axis to allow for an accurate disconnection in the plug-in zones of the two connectors.
Said connector can further comprise one or more of the following features, taken separately or in combination:
According to a preferred embodiment, the connection and disconnection mechanism comprises two actuation devices and two ejection devices respectively associated with an actuation device.
Said connector can extend longitudinally through a first and a second end lateral walls and the two actuation devices are for example arranged on the two longitudinally opposing end lateral walls of said connector.
The connector thus allows for an ergonomic control that is simple to use, and that makes it possible to connect and disconnect in a balanced manner, with no specific tool and in a blind manner.
Said connector can further comprise one or more of the following features, taken separately or in combination:
The invention also relates to a connector assembly comprising a female connector and a male connector complementing the female connector, characterized in that at least one of the connectors is as defined previously. According to a preferred embodiment, it is the female connector.
According to one aspect of the invention, the connector complementing the connector bearing the connection and disconnection mechanism has at least one housing configured to engage with and secure at least one element of the connection and disconnection mechanism.
According to an exemplary embodiment, the two connectors extend longitudinally and the housing is produced by a recess of the longitudinally opposing end walls of the connector complementing the connector bearing said mechanism.
As an alternative, the housing is produced inside the connector complementing the connector bearing said mechanism.
The complementary connector can comprise a first securing means having a slope and a bearing portion capable of cooperating with a complementary second securing means borne by the connection and disconnection mechanism.
Other features and advantages of the invention will emerge from the following description, given as a nonlimiting example, in light of the attached drawings in which:
In these figures, elements that are substantially identical bear the same references.
In
To this end, the connector assembly 1 further comprises a mechanism 7, 107, 207 for connecting and disconnecting the female connector 3 to and from the male connector 5.
The connection and disconnection mechanism 7, 107 or 207 is described in more detail hereinbelow, with reference to
The connection and disconnection mechanism 7, 107 or 207 is mounted on one or other of the connectors 3 or 5. According to the embodiments described herein, the connection and disconnection mechanism 7, 107 or 207 is mounted on the female connector 3.
Moreover, any appropriate means can be provided that makes it possible to prevent undesirable untimely actuation of the connection and disconnection mechanism 7, 107 or 207, such as a cap (not represented) arranged around the connector assembly 1. Obviously, in this case, the cap is advantageously provided with a passage formed to allow a user to easily access the connection and disconnection mechanism 7, 107, 207.
The female connector 3 is described hereinbelow in more detail.
According to the embodiment illustrated, the female connector 3 extends longitudinally substantially transversely to the plugging-in direction I.
Referring to
According to a preferred embodiment, the shell 9 is produced in a material comprising aluminum or an aluminum alloy, for example nickel-plated aluminum.
The shell 9 has, for example, a substantially parallelepipedal box form with two opposing longitudinal walls 11 and two opposing end lateral walls 13. The end lateral walls 13 are longitudinally opposite.
According to the embodiments described, the lateral walls 13 respectively form a support for the connection and disconnection mechanism 7 (
The female connector 3 can also comprise a means 15 for fixing the connection and disconnection mechanism 7 (
The fixing means 15 is for example produced using an axis 15 arranged so as to pass through at least one element of the connection and disconnection mechanism 7 (
According to an alternative, provision can be made for the female connector 3 to have an internal guiding means, for example, but in a nonlimiting manner, of dovetail type, and a fixing means such as a pin to secure at least one element of the connection and disconnection mechanism 207 in the female connector 3.
The female connector 3 further comprises a support 19 for electrical contacts. The support 19 for electrical contacts is for example arranged substantially centrally on the longitudinal axis of the female connector 3. The support 19 for electrical contacts extends for example to protrude on either side of the shell 9 of the female connector 3 in the plugging-in direction I as can better be seen in
The support 19 for electrical contacts can comprise at least one first orifice 21 or one or more rows of first orifices 21. The support 19 for electrical contacts has, for example, a general substantially parallelepipedal block form, in which the first orifices 21 are formed to receive first electrical contacts 22 that can be seen in
The number of first orifices 21 is chosen according to the number of contacts needed for the desired connection.
Moreover, according to the example illustrated, the first orifices 21 have for example a substantially cylindrical form. The first electrical contacts 22 can have a substantially cylindrical form complementing the cylindrical form of the first orifices 21.
The male connector 5, which can better be seen in
According to a preferred embodiment, the shell 23 is produced in a material comprising aluminum or an aluminum alloy. It can be the same material as the material of the female connector 3, for example nickel-plated aluminum.
The shell 23 forms a male case, of substantially parallelepipedal form, having two opposing longitudinal walls 25 and two opposing lateral walls 27. The end lateral walls 27 are longitudinally opposite.
A housing 29 (
The housing 29 (
The male connector 5 further has a first securing means 31 or 231 formed to cooperate with the connection and disconnection mechanism 7 (
The first securing means 31, 231 has, for this purpose, a slope 31a, 231a and a bearing portion 31b, 231b.
The bearing portion 31b is for example accessible from the outside of the male connector 5 according to the examples illustrated in
The cooperation between the slope 31a, respectively 231a, and the bearing portion 31b, respectively 231b, with at least one element of the connection and disconnection mechanism 7 (
As can better be seen in
Furthermore, the male connector 5 also comprises a support 35 for electrical contacts (
The support 35 for electrical contacts of the male connector 5 is arranged so as to be facing the corresponding support 19 for electrical contacts of the female connector 3 when the two connectors 3, 5 are connected. The support 35 for electrical contacts is, for example, arranged substantially centrally on the longitudinal axis of the male connector 5.
According to the embodiments illustrated, the longitudinal walls 25 and the end lateral walls 27 define between them a cavity 36 (
The support 35 for electrical contacts comprises at least one orifice 37 provided with a second electrical contact 39 configured to be connected to the complementary female connector 3 via a first orifice 21 and a first electrical contact 22 that are associated with the female connector 3.
The number and the arrangement of the orifices 37, and therefore of the second electrical contacts 39, are dependent on the number and the arrangement of the associated first orifices 21 of the female connector 3. In other words, the male connector 5 has the same number of orifices 37 as the female connector 3 and these orifices 37 are arranged so as to be facing the associated orifices 21 of the female connector 3 when the two connectors 3 and 5 are connected to one another. According to the example illustrated, the male connector 5 comprises several rows of orifices 37 provided with second electrical contacts 39.
According to the example illustrated in
The connection and disconnection mechanism 7 (
In this case, if the male connector 5 is for example arranged on an electrical circuit board, this male connector 5 which is on the electrical circuit board is not manipulated to actuate the connection and disconnection mechanism 7, 107, 207, but the complementary female connector 3 is so manipulated. The location on the electrical circuit board around the male connector 5 can therefore be left free to connect other electrical and/or electronic components.
The connection and disconnection mechanism 7 (
The connection and disconnection mechanism 7, 107, 207 comprises:
According to the embodiments illustrated, the connection and disconnection mechanism 7, 107, 207 comprises two actuation devices 41, 141, 241 and two ejection devices 45 respectively associated with an actuation device 41, 141, 241.
More specifically, the connection and disconnection mechanism 7 (
According to the first embodiment illustrated in
More specifically, referring to the orientation of the figures, a first actuation device 41 on the left in
The actuation devices 41 are for example produced in the form of two actuation levers 41 mounted on the shell 9 of one of the connectors, here the female connector 3, on the end lateral walls 13 thereof.
The actuation levers 41 can be produced, by way of nonlimiting example, in stainless material.
Referring to
The actuation devices 41 advantageously comprise at least one third gripping part 41c accessible from the outside of said connector 3.
The three parts 41a, 41b, 41c of an actuation lever 41 are, according to the example illustrated, produced in a single piece.
According to the example illustrated, the first part 41a extends longitudinally in a first direction and the second part 41b extends in a second direction different from the first direction.
The first part 41a extends for example substantially parallel to the lateral wall 13 on which the actuation lever 41 is mounted in the first connection position, the lateral wall 13 extending parallel to the plugging-in axis I in this example, that is to say substantially vertically referring to the orientation of
According to the example illustrated, it is the first part 41a of an actuation lever 41 which receives the pivoting axis 15.
The first part 41a is formed to be received in the complementary connector, such as the male connector 5 in this example. More specifically, the first part 41a is received in the recess 29 of an end lateral wall 27 of the complementary connector, here the male connector 5, when the two connectors 3 and 5 are connected to one another.
According to the first embodiment illustrated, the first part 41a and the second part 41b of the actuation lever 41 have a substantially “L” shaped form. The second part 41b extends from the first part 41a on the axis 15 to the interior of the shell 9 of the associated connector, of the female connector 3 in the example illustrated. To this end, a lateral wall 13 of the female connector 3 in this example, forming a support for the connection and disconnection mechanism 7, has an opening to receive the second part 41b of the actuation lever 41. This opening is for example formed in the lower part of the shell 9, that is to say the part opposite the part facing the complementary connector 5.
Furthermore, the second part 41b has a contact surface 47 with an associated ejection device 45. The contact surface 47 is, in the example illustrated, formed by a slope that is inclined relative to the plugging-in axis I. The angle of inclination of the contact surface 47 is chosen in such a way as to drive the ejection device in displacement when the second part 41b pivots about the axis 15, until the ejection device 45 protrudes from the plane of the connector 3, so as to push on the facing complementary connector 5 and make it possible to uncouple the two connectors 3 and 5.
The third gripping part 41c, for its part, allows for a manual actuation of the actuation lever 41 to uncouple the two connectors 3 and 5.
According to the first embodiment illustrated in
Furthermore, a second securing means 43 (
A second securing means 43 is capable of cooperating with a first complementary securing means 31 provided on the male connector 5 to which the female connector 3 is to be connected.
The securing of the connection between the female and male connectors 3, 5 is done for example by snap-fitting.
Thus, a second securing means is for example produced in the form of a hook 43 formed to cooperate with a first securing means 31 of the complementary connector 5.
To this end, the hook 43 has a form complementing the form of the slope 31a and of the bearing portion 31b. This allows for the placement and the securing of a part (here the first part 41a) of the actuation device 41 in the recess 29 of the male connector 5. In effect, when the female connector 3 is displaced along the plugging-in axis I to be connected to the male connector 5, the hook 43 is able to slide against the slope 31a until it goes beyond this slope 31a and comes to rest against the bearing portion 31b.
The hook 43 is for example formed on the side of the first part 41a of the actuation device oriented toward the interior of the female connector 3.
According to the second embodiment illustrated in
The actuation device 141 comprises a first part 141a comprising a second securing means 143, substantially similar to the first part 41a of an actuation lever 41 according to the first embodiment. This first part 141a is not therefore described again.
The actuation device 141 according to the second embodiment can further comprise a cam or thumbwheel 141b, 141c provided at the end of the first part 141a. The thumbwheel has:
As previously, an opening is formed in the lateral walls 13 of the connector bearing the connection and disconnection mechanism 107, here the female connector 3, to house the part 141b of the thumbwheel inside the female connector 3.
According to the second embodiment, the second 141b and third 141c parts of the actuation device 141 are therefore formed by the thumbwheel.
As for the first embodiment, the contact surface 147 provided on the thumbwheel forms a slope that is inclined relative to the plugging-in axis I. The angle of inclination of the contact surface 147 is chosen so as to drive the ejection device 45 in displacement when the thumbwheel, actuated manually, pivots about the axis 15, until the ejection device 45 protrudes from the plane of the female connector 3, so as to push on the facing complementary connector 5 and make it possible to uncouple the two connectors 3 and 5.
It is possible to also provide a means to facilitate the control of the gripping means, such as teeth 148 provided on the outer surface of the gripping means 141c for example produced in thumbwheel form as illustrated in
Contrary to the first or second embodiment, the actuation devices 241 according to the third embodiment illustrated in
More specifically, referring to the orientation of
The actuation devices 241 are produced at least partly in an elastically deformable material.
In a manner similar to the first embodiment and to the second embodiment, the actuation devices 241 respectively comprise:
As for the first and second embodiments, the actuation devices 241 advantageously comprise at least one third gripping part 241c accessible from the outside of said connector 3.
The three parts 241a, 241b, 241c of an actuation lever 241 are, according to the third embodiment illustrated in
Moreover, the first part 241a and the third part 241c have a substantially “L” shaped form, the first part 241a extending substantially parallel to the plugging-in axis I and the third part 421c extending substantially transversely to the plugging-in axis I toward the exterior of the shell 9 of the associated connector, of the female connector 3 in the example illustrated. The third part 241c thus protrudes from the shell 9 of the connector 3.
The second part 241b is similar to the second part 41b described with reference to the first embodiment and is not therefore described again.
The third embodiment differs also from the first or second embodiment in that the fixing axis 15 no longer serves as pivoting axis for the first part 241a.
Furthermore, the hook 243 borne by the first part 241a according to the third embodiment as illustrated in
According to an alternative illustrated in
According to this alternative, the first part 241a is advantageously mounted to move pivotably about a pivoting axis 244 on the third part 241c of the actuation lever 241. By way of example, the first part 241a is mounted on a spring 246 advantageously to allow the first part 241a to move between:
This makes it possible to facilitate the snap-fitting between the first and second securing means 231 and 243 borne by the two connectors 3 and 5, when the two connectors 3 and 5 are plugged in.
Moreover, the actuation device 241 that is translationally mobile according to the third embodiment and produced in a single piece according to the variant of
It is also possible to provide a stop making it possible to limit the travel of the actuation device 241. According to the example illustrated, the anti-rotation means 255 also ensures the stop function in the position of rest or in the position of maximum translation of the actuation device 241.
By way of illustrative and nonlimiting example, the anti-rotation means 255 is for example produced in a substantially oblong form.
It is also possible to provide for the anti-rotation means 255 to be capable of receiving a fixing means such as a pin (not visible in the figures) mounted on both sides of the shell 9.
The ejection device 45 is distinct from the associated actuation device 41 or 141 or 241. More specifically, the ejection device 45 and the associated actuation device 41, 141, 241 are produced by two separate pieces.
The ejection devices 45, for their part, are mounted to move translationally in the plugging-in direction I of the female and male connectors 3, 5, between a position of rest and an ejection position in which they are capable of exerting a force on the facing complementary connector 5 so as to uncouple the connector assembly.
According to the embodiment described, in the rest position, an ejection device 45 is retracted inside the connector, for example the female connector 3. The surface of the ejection device 45 is then situated below, or is flush with, the surface of the associated connector, of the female connector 3 in the example described.
In the ejection position, the ejection device 45 protrudes from the surface of the associated connector, of the female connector 3 in the example described.
In the example illustrated in
The ejection devices 45 are for example produced in the form of pieces or plungers 45.
The pieces 45 are, by way of example, produced in a material capable of absorbing the impact, by way of example in stainless material, which is for example passivated, or, as a variant, in plastic material to avoid damaging the shell 23 of the complementary connector 5 on which the pieces 45 are intended to apply a force. As a variant, or in addition, protection means can be provided, for example produced in the form of complementary pieces, provided on the complementary connector 5, at the level of the impact with the ejection devices 45.
The pieces 45 can have a head 49 capable of sliding over the corresponding contact surface 47, 147, 247 and a body 51 capable of pushing on the complementary connector, such as the male connector 5, when it is protruding in the ejection position. The body 51 extends along the plugging-in axis I of the two connectors 3 and 5, so as to allow a disconnection of the connectors 3 and 5, in the same direction as for the connection and the plugging-in of the two connectors 3, 5. The head 49 and the body 51 of a piece 45 can be produced in a single piece.
It is also possible to provide a means 53 for returning each ejection device 45 into the rest position. It is for example a return spring 53 such as a compression spring. Only one return spring 53 is illustrated in
The method for connecting the male and female connectors 5, 3 as described previously is performed as follows with reference to
Thus, in order to mechanically and electrically connect the two disassembled female and male connectors 3, 5 as illustrated in
The two connectors 3, 5 are plugged in the plugging-in direction I, such that the actuation devices 41 or 141 borne by one connector 3 are inserted at least partially into the corresponding housings on the other connector 5, and come to be fixed in the other connector 5.
More specifically, the first parts 41a (or 141a) of the actuation devices 41 (or 141) borne by one connector, such as the female connector 3, are inserted into the housings 29, for example produced by recesses 29, provided on the other connector, such as the male connector 5. This is schematically represented in
The plugging in of the two connectors 3, 5 along the axis I drives the securing hook 43 (or 143) provided at the end of each actuation device 41 (or 141) to slide over the slope 31a of the first securing means 31 of the complementary connector, here the male connector 5, such that each actuation device 41 (or 141) pivots slightly outward from the connector 3 as schematically represented in
By continuing to plug in the two connectors 3 and 5 along the axis I, the hooks 43 (or 143) go beyond the slope 31a and come to bear against the corresponding bearing portions 31b provided on the complementary connector, such as the male connector 5, as schematically represented by
The two connectors 3 and 5 are thus kept connected by virtue of the snap-fitting of the actuation devices 41 (or 141) borne by one connector, such as the female connector 3, on the other complementary connector, such as the male connector 5.
In this plugged-in position of the two connectors 3 and 5, the second electrical contacts 39 (see
It is possible to provide an additional step of capping of the connector assembly 1 making it possible to avoid an untimely actuation of the connection and disconnection mechanism 7 (or 107 or 207).
Referring to
Starting from the disassembled position of the two connectors 3 and 5 illustrated in
By continuing the plugging-in of the two connectors 3 and 5 along the axis I, the hooks 243 are located against the associated first securing means 231 of the complementary connector, here the male connector 5, as illustrated in
In addition or as an alternative, it is possible to produce the actuation device 241 at least partially in an elastically deformable material, in particular at the level of the second securing means 243.
According to another alternative of the actuation device 241 in two parts, represented schematically in
Regarding the first or the second embodiment, in order to disconnect the two plugged-in connectors 3 and 5 as represented in
According to the embodiments illustrated, the two actuation devices 41 (
Upon the pivoting of the actuation device 41 or 141 toward the disconnection position, the associated ejection device, such as a piece 45, is driven in translation along the plugging-in axis I by the actuation device 41 or 141. More specifically, the ejection device 45, for example the head 49 of the piece 45, slides over the contact surface 47 or 147 of the associated actuation device 41 or 141 and the ejection device 45, for example the body 51 of the piece 45, is displaced in translation along the plugging-in axis I toward the other complementary connector, such as the male connector 5 (upward with reference to the orientation of
The ejection devices 45, more specifically the bodies of the pieces 45 in this example, are located protruding from the plane defined by the connector 3 bearing the connection and disconnection mechanism 7 or 107, so as to push on the facing complementary connector 5 and thus provoke the separation of the electrical contacts 22, 39 of the male connector 5 and of the female connector 3.
The method for disconnecting the connectors 3 and 5, one of which bears a connection and disconnection mechanism 207 according to the third embodiment differs in that, to disconnect the two plugged-in connectors 3 and 5 as represented in
In a manner similar to the first or second embodiment, the associated ejection device 45, more specifically the head 49, then slides over the contact surface 247 of the associated actuation device 241 and the ejection device 45, for example the body 51 of the piece 45, is displaced in translation along the plugging-in axis I toward the other complementary connector, such as the male connector 5 (upward with reference to the orientation of
Thus, it will therefore be understood that with such a connection and disconnection mechanism 7, 107 or 207, for connecting (or coupling) the two connectors 3 and 5, the actuation devices 41, 141, 241 come to be fixed, for example by snap-fitting, in a simple manner to the complementary connector 5. No particular manipulation is required. Furthermore, return springs 53 can make it possible for the actuation devices 41, 141 to remain in the locked rest position.
Regarding the uncoupling or disconnection of the two connectors 3 and 5, it is sufficient to exert a pressure on the gripping parts 41c, 241c according to the first and third embodiments, or a rotational movement of the thumbwheels 141c according to the second embodiment, to drive the two pieces 45, so as to push on the facing connector and uncouple the connection.
In conclusion, the connection and disconnection mechanism 7, 107, 207 according to the invention makes it possible to couple and uncouple the two connectors 3 and 5 in total safety, with no tools and blind. In effect, the simplicity of the connection and disconnection mechanism 7, 107, 207 and the absence of the need for specific tools makes it possible to disconnect the two connectors 3 and 5 without even seeing them.
Furthermore, that makes it possible to uncouple the two connectors 3 and 5 in the plugging-in direction I, in the alignment of the connection spindles without damaging them, with no random movements and without pulling on the cables.
The connector assembly 1 is therefore ergonomic and easy to use, with intuitive connection or disconnection.
