Definitions

  • the invention relates to a connector part according to the preamble of claim 1.
  • Such a connector part comprises a housing part which has a plug section which can be plugged into an associated mating connector part in a plug direction.
  • a latching plate is attached to the housing part and has at least one latching element for latching with the mating connector part in a position of the connector part plugged into the mating connector part and at least one engagement element.
  • On the housing part there is also an actuating element which is displaceable in the opposite direction to the housing part and has an unlocking element which is designed to interact with the mating connector part with the mating connector part when the actuating element is displaced in the opposite direction to release the latching of the latching plate, wherein the actuating element is spring-biased in the insertion direction with respect to the housing part via at least one spring element.
  • a corresponding connector part is for example from the US 2015/0229075 A1 , of the EP 1 744 408 A1 , of the US 5,634,809 A and the EP 1 341 268 A2 known.
  • US 5,634,809 A and EP 1 341 268 A2 each disclose the preamble of claim 1.
  • a male part means e.g. a plug attached to the end of a cable or a built-in plug installed in a device housing.
  • a female part means e.g. a coupling attached to the end of a line or a socket installed in a device housing.
  • the male part can be inserted into the female part and has e.g. protruding contact pins, which are to be inserted into associated contact openings of the female part.
  • Known connector for optical fibers comprises a connector housing on which optical fibers are held with ferrules arranged thereon.
  • the connector housing with the optical fibers arranged thereon can be inserted into an assigned socket or a coupling in order to establish an optical contact in this way.
  • a sliding sleeve is arranged on the connector housing, which serves to engage loosen between the connector housing and an associated socket or coupling for pulling the plug housing from the socket or the coupling.
  • the connector of the DE 10 2009 011 388 B3 Realizes in this way a connector according to the so-called push-pull system, in which a latching connection can be established in a simple manner by inserting the connector into an assigned socket or coupling, which is released again in a simple, convenient manner by actuating the sliding sleeve can be.
  • Push-pull connectors are, for example, from the DE 10 2005 025 769 B3 , of the DE 20 2009 010 037 U1 , of the DE 10 2007 031 504 A1 , of the DE 10 2013 113 631 B3 and the EP 2 978 079 A1 known.
  • a housing part has a locking plate with locking elements arranged thereon.
  • a connector part in which a locking element is integrally formed with a housing part.
  • a locking plate which is made of spring steel, for example, and is thus at least in sections elastically resilient, can be used on the one hand for locking with the mating connector part and on the other hand for resetting the actuating element.
  • This can have the disadvantage that when the connector part moves, for example as a result of vibrations, the locking of the connector part with the mating connector part can be unintentionally released, because the locking element of the locking plate is lifted out of an associated mating locking element of the mating connector part.
  • the object of the present invention is to provide a connector part which is reliably locked in a position plugged into the associated mating connector part and in which unintentional loosening is at least made more difficult.
  • the actuating element is, for example, by one or more spring elements e.g. spring-biased in the direction of insertion in the form of compression springs in relation to the housing part.
  • a latching plate and a spring element can be provided on both sides of the housing part.
  • a first locking plate is thus arranged on a first side of the housing part and a second locking plate in a symmetrical manner on a second side of the housing part facing away from the first side.
  • the first side and the second side are each assigned a spring element, so that the actuating element on the sides of the housing part, on which a locking plate is arranged, is also spring-biased relative to the housing part.
  • the spring element can, for example, lie in an opening of the actuating element, for example in a web extending centrally above the slot between the fingers of the locking plate.
  • the spring element is thus supported on the actuating element and, on the other hand, on the housing part, for example on a projecting pin of the housing part or a component firmly connected to the housing part, for example a back part facing away from the plug-in section of the housing part, which is firmly connected to the housing part.
  • the actuating element In a non-actuated position, the actuating element is preferably not in contact with the at least one engagement element of the locking plate via the unlocking element. On In this way it is avoided that small movements on the actuating element, for example as a result of vibrations or the like, cannot lead to the latching plate being triggered, so that unintentional detachment of the connector part from its position plugged into the mating connector part is not readily possible.
  • the (at least one) spring element is preferably designed such that it holds the actuating element in the non-actuated position under pretension. If the actuating element is not actuated, it is thus held in the position it has just assumed under resilient prestress, preferably in such a way that the unlocking element of the actuating element is spaced apart from the engagement element of the locking plate along the plug-in direction and thus an interaction between the unlocking element of the actuation element and the engagement element of the Locking plate is prevented when the actuating element is not actuated.
  • the unlocking element on the side of the actuating element and the engagement element on the side of the locking plate are thus separated from one another when the actuating element is not actuated. Only when actuated did the unlocking element come into contact with the engagement element in order to move the locking plate in order to release the locking.
  • the actuating mechanism is insensitive to tolerances. Tolerances in the position of the actuating element and the locking plate relative to one another can be compensated (elastically), the distance between the unlocking element of the actuating element and the engagement element of the locking plate being preferably dimensioned when the actuating element is not actuated, so that there is no tolerance between the unlocking element, regardless of tolerance and the attack element comes when the actuating element is not actuated.
  • the at least one latching element can be moved in a vertical direction by displacing the actuating element to release the latching, the at least one engagement element along one transverse to the vertical direction and transverse to the Plug direction directed transverse direction and is also offset against the plug direction relative to the at least one locking element.
  • the latching element and the engagement element are thus spatially separated from one another. This enables the actuating element, when actuated to release the latching, not to act directly on the latching element, but at other locations, namely on the engagement element spatially separated from the latching element.
  • the at least one engagement element is set back relative to the at least one latching element, viewed along the direction of insertion, makes it possible to provide an increased stroke for releasing the latching due to an extended lever arm on the latching element.
  • a comparatively small stroke on the engagement element can lead to a comparatively large stroke on the latching element. Because a comparatively large stroke on the latching element is required to release the latching and thus the engagement with associated counter-latching elements on a mating connector part can be improved, releasing the latching e.g. in the case of vibrations on the connector part, which can also cause the locking plate to vibrate on the housing part, at least more difficult.
  • the height direction along which the locking element is moved to release the locking is directed perpendicular to the direction of insertion.
  • the latching element is lifted out of an associated counter latching element on the side of the mating connector part, so that a positive connection between the connector part and the mating connector part is released.
  • the latching element is preferably designed to be elastically resilient.
  • the locking plate can be made of a metal, in particular a spring steel.
  • the latching element on the latching plate can, for example, have a latching opening into which an associated latching pin engages on the part of the mating connector part when the connector part is plugged into the mating connector part.
  • the latching element is raised in relation to the latching pin in such a way that the engagement of the latching pin in the latching opening is canceled and the positive fit between the connector part and the mating connector part is thus released.
  • the at least one engagement element is preferably formed by a tab extending obliquely to the height direction.
  • The, for example, wedge-shaped unlocking element of the actuating element runs onto the attack element when the actuating element is displaced towards the housing part in the opposite direction to the plug-in direction. Due to the oblique orientation of the engagement element, the locking element of the locking plate is raised, so that the locking between the locking plate and the mating connector part is released.
  • the locking plate is, for example, positively attached to the housing part.
  • the locking plate is designed as a separate component and is attached to the housing part, for example, via one or more fastening tabs.
  • the fastening tabs can preferably be arranged on an end of the locking plate which is remote from the locking element.
  • One or more locking elements are thus formed at one end of the locking plate, while the locking plate is firmly connected to the housing part at the other end.
  • the locking plate at its end carrying the locking elements can be raised relative to the housing part, so that in this way a locking with an associated one Mating connector part can be solved.
  • the end of the latching plate carrying the latching elements is lifted with elastic deformation of the latching plate, so that after actuation of the actuating element and after resetting the actuating element, the latching plate is automatically returned to its undeformed starting position.
  • the latching plate has, for example, a surface section and two fingers which are extended from the surface section and are separated from one another by a slot. On each finger a locking element for locking with the mating connector part and an engagement element for interacting with the unlocking element, the actuating element is formed.
  • each finger has a latching element and, preferably on the inside, an engagement element for interacting with the unlocking element of the actuating element, each finger of the latching plate is actuated separately when the actuating element is actuated to release the latching.
  • the slot between the fingers is preferably extended along the direction of insertion. Accordingly, the fingers extend along the direction of insertion from the surface section of the locking plate.
  • the actuating element is formed by a (sliding) sleeve encompassing the housing part.
  • the actuating element thus takes up the housing part.
  • a user can engage the actuating element and move it towards the housing part against the plugging direction.
  • the locking of the connector part with the mating connector part is released, and the connector part can also be pulled off the mating connector part by the pulling movement.
  • a connector assembly has a connector part of the type described above and a mating connector part.
  • the connector part can, for example, implement a so-called male part in the form of a plug, which can be inserted into a so-called female part in the form of a socket or the like.
  • the connector part with the Mating connector part latched, the latching being released by actuating the actuating element counter to the plugging direction and the connector part being able to be removed from the mating connector part.
  • Fig. 1 shows a perspective view of a connector part 1 with a housing part 10, which forms a plug section 100 at a front end and in a plug direction E to an associated mating connector part 3 (see 7A to 7C ) can be infected.
  • An actuating element 11 in the form of a sliding sleeve is arranged on the housing part 10, displaceable along the plug-in direction E. The to release the connector part 1 from the mating connector part 3 in a pulling direction Z, which is opposite to the plugging direction E, can be actuated.
  • a rear part 12 is arranged, which is fixedly connected to the housing part 10 and forms a pin 13 via which an electrical line 2 (see Fig. 1 as well as the 7A to 7C ) inserted into the housing part 10 and can be fixed relative to the housing part 10 via a fixing element 14.
  • the connector part 1 realizes a connector according to the push-pull principle. As in 7A to 7C shown, the connector part 1 can be attached in the plug direction E to the assigned connector part 3 by plugging the plug section 100 of the plug connector part 1 into an assigned plug opening 300 on a plug section 30 of the mating plug connector part 3.
  • the connector part 1 realizes a so-called male connector, which can be inserted with its plug section 100 into the assigned plug opening 300 of the mating connector part 3 realizing a female plug connector.
  • the mating connector part 3 is arranged on a wall 4, for example of a control cabinet or a system or the like.
  • a contact insert is received, which forms a plug face with the mating connector part 3 facing contacts within an opening 101 of the plug section 100, which contacts the mating connector part 3 on the mating connector part 3 side when the plug connector part 1 is mated with the mating connector part 3 reach.
  • the contacts of the connector part 1 can, for example, implement electrical or optical contacts. An electrical or optical connection to the mating connector part 3 can thus be established via the connector part 1.
  • two locking plates 15 are arranged on opposite sides, which serve to produce a latching between the connector part 1 and the mating connector part 3 when the connector part 1 is plugged into the mating connector part 3.
  • the latching plates 15 each have a surface section 150, from which bent tabs 156 protrude, which grip around the housing part 10 and form a positive, fixed connection with the Manufacture housing part 10. The locking plates 15 are thus fixed to the housing part 10.
  • Two fingers 151 which are separated from one another by a slot 152, each extend from the surface section 150 of each locking plate 15 and each carry a locking element 153 with a locking opening and an engagement element 155 in the form of a bent, obliquely extended tab. If the connector part 1 is plugged into the assigned mating connector part 3 in the plugging direction E, the latching elements 153 with associated mating latching elements 301 in the form of latching pins reach the plug section 30 of the mating connector part 3 (see Figure 7C ) engaging in engagement, so that when the connector part 1 is plugged in, there is a positive connection between the counter-locking elements 301 and the locking elements 153. The connector part 1 is thus held in a latching manner on the mating connector part 3.
  • a user can grip the actuating element 11 in the form of the sliding sleeve with one hand and move the actuating element 11 in the pulling direction Z opposite the plug direction E with respect to the housing part 10.
  • the actuating element 11 has a sleeve-shaped body 110, within which the housing part 10 is received.
  • two unlocking elements 111 are arranged on a front circumferential edge 114 of the body 110 facing the plug-in section 100, each of which has a wedge shape and with its wedge-shaped tips each faces one of the engagement elements 155, as shown in FIG 3 and 4 can be seen.
  • the engagement elements 155 run in the form of the obliquely extended tabs on the unlocking elements 111, so that the fingers 151 of each locking plate 15 are raised in a height direction H and thus out of engagement with the counter-locking elements 301 on the part of the counter-connector part 3 are brought.
  • the latching between the connector part 1 and the mating connector part 3 is released, so that the connector part 1 can be removed from the mating connector part 3 by further pulling on the actuating element 11.
  • the actuating element 11 in the form of the sliding sleeve is biased in the plugging direction E relative to the housing part 10.
  • two spring elements 16 in the form of compression springs are arranged between the actuating element 11 and the rear part 12 which is fixedly connected to the housing part 10, a spring element 16 for prestressing the spring element 16 also being arranged on the sides of the housing part 10, on each of which a locking plate 15 is arranged Actuating element 11 is provided opposite the housing part 10.
  • each spring element 16 lies in an opening 113 on a web 112, which extends longitudinally along the plug-in direction E, on the inside of the body 110 of the actuating element 11 and is, as from Fig. 3 can be seen supported at one end on the actuating element 11. At the other end, the spring element 16 is plugged onto a pin 120 on the back part 12 and is supported above it on the back part 12 and thus against the housing part 10. When pulling the actuating element 11 in the pulling direction Z, the spring elements 16 are thus tensioned so that after actuation, the actuating element 11 is automatically reset in the insertion direction E relative to the housing part 10.
  • the spring elements 16 hold the actuating element 11 in its just occupied, non-actuated position. This is done under spring elastic prestress.
  • a sealing element 102 Arranged on the plug section 100 is a sealing element 102 in the form of a circumferential sealing ring which, when the plug connector part 1 is plugged into the mating plug connector part 3, produces a sealing transition between the plug section 100 on the plug part 1 side and the plug section 30 on the mating plug part 3 side.
  • each locking plate 15 has two fingers 151, which are separated from one another by a central slot 152, improves the elasticity of the locking plate 15, which is made of spring steel, for example. Because each finger 151 has a latching element 151 and an engagement element 155, each finger 151 is actuated by itself when the actuating element 11 is actuated, with the latching plate 15 being elastically deformed.
  • each latching element 153 has a bent edge 154, which can serve, for example, as an end stop for the actuating element 11.
  • the front edge 114 of the actuating element 11 can come into contact with the edges 154, so that the actuating element 11 can no longer be actuated in the pulling direction Z.
  • attack elements 155 as shown in particular from the enlarged view Fig. 6 can be seen in a transverse direction Q transversely to the plugging direction E and transversely to the height direction H with respect to the latching elements 153 and are also set back against the latching direction E, i.e. in the pulling direction Z, with respect to the latching elements 153 (in particular, the engagement elements 155 are opposite the front edge 154 set back in the pulling direction Z), a locking which is insensitive to movements (in particular as a result of vibrations) on the connector part 1 can result.
  • the latching elements 153 Compared to the engagement elements 155, the latching elements 153 have an enlarged lever arm (measured from the surface section 150 fixed on the housing part 10), which causes a comparatively small stroke on the engagement elements 155 to a larger stroke on the latching elements 153, in particular the latching openings the locking elements 153, leads.
  • the counter-latching elements 301 on the side of the mating connector part 3 can thus be designed with a greater height, so that an improved engagement between the latching elements 153 of the latching plate 15 and the associated counter-latching elements 301 of the mating connector part 3 can be created.
  • unlocking elements 111 of the actuating element 11 are not in contact with the engagement elements 155 in the non-actuated position of the actuating element 11, so that small movements on the actuating element 11, for example as a result of vibrations, do not lead to the latching being released.
  • each locking plate 15 can be positively engaged with the locking elements 301 on the respectively assigned one Surface of the plug section 30 of the mating connector part 3 rest without the actuating element 11 preventing this.
  • the fingers 151 of the locking plates 15 each rest on a web 103 on the associated side of the housing part 10, for example from 5 and 6 as well as from the cross-sectional view according to Fig. 3 can be seen.
  • the web 103 creates a defined support for the associated latching plate 15.
  • the web 103 constitutes an end stop for the plug section 30 of the mating connector part 3, so that the plug section 100 of the housing part 10, with the plug connector part 1 plugged in, has a defined position relative to the plug section 30 of the mating connector part 3 occupies.
  • a connector part of the type described here can be used to contact very different lines with one another and for this purpose, for example, provide electrical or optical or other contacts, for example hydraulic contacts or the like.
  • Such a connector part can be used, for example, in an industrial plant or the like.
  • lines can be connected to a control cabinet via such a connector part.
