Definitions

  • the invention refers to the field of connection systems with at least one first and one second connector element which are insertable one into the other.
  • the invention relates to such connection system with at least one first and one second connector element which are insertable one into the other, comprising an insertion obstruction device, and further comprising an abutting arrangement being connected to said first connector element via a resilient, preferably arm-like connecting member and abuttable against the second connector element in at least a portion of the insertion path according to the preamble of claim 1.
  • Connection systems are used especially e.g. for multipolar electrical connectors and are applied, amongst others, in automotive engineering, mechanical engineering and in electrical machines and devices, where they serve, e.g., as electrical connectors for detachably connecting junctions of cables and are known in a vast variety of embodiments.
  • the progression of force occurring along the insertion path during mounting of the connector can hardly be predefined and adapted to the mounting requirements in an optimal way.
  • an objectionable or unwanted connecting of the connector parts may occur if the insertion resistance is too small. For this reason, the working efficiency is significantly reduced and incorrect mounting cannot reliably be prevented without controlling efforts.
  • EP 0 923 167 A1 proposes a connector, comprising a first connector element and a second connector element which can be pushed one into the other and, upon complete insertion of the connector elements, said elements releasibly be locked together.
  • the first connector element comprises an arm-like abutting and locking member being resiliently connected to said first connector element and a spring element, providing an insertion obstruction force, which is directed against insertion direction of the connector elements and capable of pushing apart the connector elements, attached to the second connector element and abuttable in a portion of the insertion path against the arm-like abutting and locking member of the first connector element. Only in case of overriding the insertion obstruction force of the spring element, a complete mounting of the connector elements and engaging of the arm-like abutting and locking member of the first connector element with a locking counter-structure of the second connector element, can be achieved.
  • an object of the present invention to provide a connecting system with an insertion obstruction device according to the preamble of claim 1 providing for such insertion obstruction device a simple and single integral component arrangement which can be either retroactively fitted or simply integrated into line productions of existing connector designs with reasonable adaptation effort and can be exactly adjusted considering progression of mounting force over course of the insertion path and point of deactivation of insertion obstruction device in a wide range to the mounting prerequisites of the connectors and eliminates the above-mentioned disadvantages.
  • a connecting system with at least a first and a second connector element which are insertable, one into the other, comprising an insertion obstruction device, and further comprising an abutting arrangement being connected to said first connector element via a resilient, preferably arm-like connecting member and abuttable against the second connector element in at least a portion of the insertion path, wherein said abutting arrangement is part of the insertion obstruction device and movable in insertion direction in an abutted state in respect of the first connector element wherein the abutted state is deactivatable upon further insertion of the connector elements and said abutting arrangement is movable in the insertion direction in respect of the second connector element.
  • the insertion forces can be adjusted to the mounting requirements over a wide range of force and precisely preset. At the same time, the insertion forces can largely be maintained independently from mounting temperature, humidity, contamination of the contacting areas, unbalanced insertion force, canting, squeezing or compression of connector housings, mounting caused wear in case of multiple mounting procedures and other factors.
  • a construction according to the present invention permits the exertion of large insertion obstruction forces and insertion obstruction works without additional constructional expense or causing overstraining of material and construction of the connector elements. Additionally, the connector arrangement is set free of tension after releasing of the insertion obstruction device causing a relaxation of the loaded spring element.
  • the insertion obstruction device can be configured to be exchangeable or retrospectively mountable so that it becomes possible to provide connection systems with different mounting characteristics and so to organize a modular system of connectors and insertion obstruction devices at little production expenses.
  • the rising characteristics of the insertion obstruction force preferably to the mounting prerequisites and to the type and construction and the operating conditions of the connectors. It may often be favourable and can easily be achieved to produce by such insertion obstruction device an insertion obstruction force being substantially larger than the frictional forces during mounting of the connector wherein the insertion obstruction force can be provided over a substantial portion of the insertion path by which, in case of incorrect mounting of the connection, the connector parts, for example, can be pushed apart and largely be separated from one another so that, for example, the connector parts automatically become undone. Thus, any incorrect mounting can immediately be recognized.
  • the point of deactivation of the insertion obstruction device along the insertion path can be exactly set and preset in compliance with the technical requirements. It may often be beneficial to deactivate the insertion obstruction device prior to occurrence of a maximum of a sum of all other insertion resistances except the ejecting force. In such way, it is, for example, possible to reliably ensure the accurate mounting even in cases of tight connectors, which are difficult to be mounted, featuring several pronounced pressure points, which otherwise would deceive the assembler. Thus, the delusive pressure points can reliably be overridden by the exceeding moment of force, when abruptly deactivating the insertion obstruction device, so that accurate mounting can be secured.
  • the point of deactivation of the insertion obstruction device at a later point of the insertion path or possibly after locking of the connector elements so that the connector elements in any circumstance become undone unless insertion and locking of the connector elements is thoroughly completed.
  • the load peak generated by the insertion obstruction device versus the insertion stroke of the connector elements relative to one another and in relation to the meshing action of for example electrical contacts of contact pins and contacting counter-structures or for example sealing structures can be phased in accordance with the equipment and construction of the connector and with the customers' mating requirements.
  • the maximum insertion obstruction force is dimensioned so that this force is significantly larger, preferably substantially at least twice as large as the maximum of the sum of all other insertion resistances except the ejecting force which occurs during mounting of the connector parts along the insertion path.
  • this force is significantly larger, preferably substantially at least twice as large as the maximum of the sum of all other insertion resistances except the ejecting force which occurs during mounting of the connector parts along the insertion path.
  • a further advantage of the connecting system according to the present invention can be that, in case of a force controlled assembly, in which a force for mounting the connector parts is preset and applied, the insertion obstruction device is only deactivated upon exceeding of a predefined minimum mounting force so that only in such case the mounting of the connector part can subsequently be accomplished.
  • the insertion obstruction device may comprise a spring element made of a resilient, preferably metal-like material by which the abutting arrangement is guided and resiliently connected to the first connector element.
  • the abutting arrangement may comprise a shaped part of a preferably polymeric material being attached to one free end of the spring element.
  • Such abutting arrangement can be formed three-dimensionally in an especially functional, simple, and competitive way and be provided with freely shapable functional portions so that optimal operation of the insertion obstruction device can be achieved at little manufacturing expenses.
  • said shaped part of the abutting arrangement may comprise at least one, preferably two, specifically formed contacting faces being arranged for interacting with at least one of the connector elements.
  • the insertion obstruction device and abutting arrangement are producible in a single integral part.
  • the insertion obstruction device can easily be configured exchangeable or retrospectively mountable so that it becomes possible to provide connection systems with different mounting characteristics and so to organize a modular system of connectors and insertion obstruction devices with little production expenses. Additionally, it is conceivable to simply integrate such insertion obstruction device into line productions of existing connector designs with reasonable adaptations and to exactly adjust the characteristic curve of mounting force over course of the insertion path and point of deactivation of insertion obstruction device in a wide range to the mounting prerequisites of the connector design and equipment and the customers' requirements.
  • An insertion obstruction device may thus be of a single material exhibiting an abutting arrangement being composed of a specifically formed portion of for example a homogenous polymeric or metal-like spring element or a composite component part of two material components like a metal-like spring element to which a shaped part of for example a polymeric material is e.g. integrally moulded or materially bonded.
  • the abutting arrangement may - in a portion of the insertion path - simultaneously be abuttable in the insertion direction against functional sections of the housings of both connector elements in which the first connector element is abuttable against the second connector element via the abutting arrangement.
  • the abutting arrangement may, in a portion of the insertion path, be movable perpendicularly to the insertion direction and in its entirety be removable from the centre line connecting the centers of the connector elements in the insertion direction.
  • an ejecting force which is directed against the insertion direction may be producible by the spring element.
  • the insertion obstruction device may comprise a preferably substantially U-shaped leaf spring or structural spring which is preferably loadable with a force substantially in a direction of one arm of said leaf spring or structural spring.
  • the insertion obstruction device may abruptly be deactivatable upon insertion of the connector elements.
  • the abruptly suspended ejecting force by deactivation of the insertion obstruction device and simultaneous persistence of an insertion operation force being effective in the insertion direction and applied to the connector elements, an exceeding moment of force in the insertion direction compared to the entirety of all other insertion resistance forces except the ejecting force, consisting mainly of the frictional and meshing forces of connector housings, sealing components and electrically contacting structures, occurring during mounting is achievable.
  • the insertion obstruction device when inserting the connector elements in the insertion direction, may be deactivatable prior to occurrence of a maximum of a sum of all other insertion resistances except the ejecting force.
  • the load peak generated by the insertion obstruction device versus the insertion stroke of the connector elements relative to one another and in relation to the meshing action of, for example, electrical contacts of contact pins and contacting counter-structures or for example sealing means can be phased in accordance with the customers' mating requirements.
  • a minimum mounting force for inserting and mounting the connector elements may be definable by the insertion obstruction device, upon excess of said minimum mounting force, the insertion obstruction device may be deactivatable and mounting of the connector elements may be achievable.
  • Such construction may especially be preferred in case of force controlled mounting as it comes into effect, for example, in case of assembly by hands without support or with not-path-controlled or not-path-restricted auxiliary mounting devices to produce a well-defined exceeding moment of force for securing the correct mounting.
  • a well-defined force feedback is given to the assembler and thus, an accidental connecting of the connector elements can be prevented and simultaneously, in case of desired locking of connecting elements, an accurate mounting and securing can be ensured.
  • a maximum of the ejecting force over the course of the insertion path may preferably be substantially at least twice as large as the maximum of all other insertion resistances over the course of the insertion path except the ejecting force.
  • the spring element may be deformable upon insertion of the connector elements by direct action of an insertion force and tiltable in a linkage point of the abutting arrangement.
  • Such tilting of the spring element can be used in a preferable manner to incline the abutting arrangement from its initial position and thus, to support the deactivation of the insertion obstruction device.
  • a tilting of an abutting surface of the abutting arrangement in respect of a section of the housing of the second connector element being in contact with said abutting surface may be achievable by which the abutting arrangement may be tiltable off its abutting position and the insertion obstruction device may be deactivatable.
  • the spring element can actuate, induce or trigger the deactivation of insertion obstruction device without assistance or cooperation from further appliances.
  • said tilting of the abutting arrangement may be actuatable and/or supportable by a tilting supporting arrangement which is preferably operatable upon insertion of the connector elements.
  • said tilting supporting arrangement may be an integral functional portion, preferably a tapered portion or inclined portion of a section of the housing of one connector element.
  • the tilting supporting arrangement may be attached to a section of the housing of that connector element to which the abutting arrangement is resiliently connected and is approachable in an abutted state of the abutting arrangement towards the abutting arrangement and is interactable with said abutting arrangement.
  • the spring element and the abutting arrangement may be interactable with at least one section of the housing of one connector element or of two connector elements in a manner that the abutting arrangement, which is soundly abutting against at least one portion of one connector element in case of no or little deformation of the spring element, may be tiltable off the abutting position by further deformation of the spring element and/or by interaction with at least one section of the housing of one connector element or two connector elements and may be slidable off said abutting position.
  • said several components e.g. spring element, abutting element and portions of the housings of the connector elements
  • the connecting system may further comprise a locking mechanism which may preferably comprise a locking means, preferably a locking arm, being loaded by an elastic force, attached to one connector element and a locking counter means attached to the other connector element whereby the connector elements are lockable in a mounted state.
  • a locking mechanism which may preferably comprise a locking means, preferably a locking arm, being loaded by an elastic force, attached to one connector element and a locking counter means attached to the other connector element whereby the connector elements are lockable in a mounted state.
  • the locking mechanism ensures a durable long lasting connection without risk of accidental loosening or untightening.
  • the insertion obstruction device can reliably assure the accurate and completed mounting and locking of the connector elements which is, in this case, of particular importance.
  • an unwanted locking of a connector element can be prevented or rendered unlikely while the insertion obstruction force reaches a sufficiently large value which counteracts an undesirable moving together and engaging of the connector parts. In this way, incorrect locking and mounting of the connector elements can be prevented which, otherwise, would have to be laboriously separated.
  • the assembler obtains a high degree of mounting reliability. In doing so, it can also be prevented that tight connector combinations may be damaged by applying an overlarge mounting force, which also saves significantly costs and labour for replacing damaged connector elements. Simultaneously, the reject rates of incorrectly mounted connectors can significantly be lowered even without applying sumptuous retroactive control.
  • the insertion obstruction device may spatially and functionally be separated from the locking device, wherein the insertion obstruction device may preferably be located on a side opposite to the locking device in relation to the centre line of the housing of the first connector element.
  • the connecting system may be a connecting system for electrical connectors, preferably multipolar electrical connectors wherein the advantages according to the present invention come into effect in an especially favourable manner.
  • the inner sleeve (16) is provided with sealing elements (14) by which the clearances for the installation of the spring eye bushings (13) and the gap between the inner sleeve (16) of the first connector element (1) and the housing of the second connector element (2) can be sealed.
  • the portion of the inner sleeve (16) being located at the end of the spring eye bushing (13) is inserted into the housing of the second connector element (2) and is centred in relation to the insertion axis by guiding structures such as guide rips (17).
  • a contact pin (12) being provided for contacting with the spring eye bushing (13) of the first connector element (1) is located in the second connector element (2) and fixed aligned with the spring eye bushing (13). This contact pin (12) is - in the state depicted in this Figure - not yet in contact to the spring eye bushing (13) of the first connector element (1) but is spaced apart from it in insertion direction (E).
  • the components described so far are also present in a standard connector of the state of the art.
  • the connector according to the present invention exhibits, in the here-described embodiment, furthermore, an insertion obstruction device (3) with a structural spring element (8) bent in U-shape, the one arm of which is permanently or removably coupled to the inner sleeve (16) of the first connector element (1).
  • the other arm of the U-shaped structural spring element (8) comprises an abutting arrangement (4) made of a polymeric material and being integrally connected to the spring element (8), which can be achieved by for example integrally moulding or materially bonding said abutting arrangement (4) to said spring element (8).
  • the abutting arrangement (4) shows in its end portion being located in the insertion direction (E) an abutting surface (6) which, in this state of mounting depicted in Fig. 1, slightly abuts against the supporting counter surface (5) of the housing of the second connector element (2).
  • a tapered portion (19) is located which corresponds to - and is designated for interaction with - a respective tapered portion (7) of the inner sleeve of the first connector element (1) and is, due to its orientation, adapted and provided to travel the abutting arrangement (4) when pushing the tapered portion (7) of the first connector element (1) against the tapered portion (19) of the abutting arrangement (4) and to remove the abutting arrangement (4), at least at its end which is opposite to the insertion direction (E), in respect of the centre line (C).
  • a region of the inner sleeve (16) being adjacent in a direction opposite to the insertion direction (E) to the tapered portion (7) of the first connector element (1) is shaped to form a spring stop unit (18), for the spring element (8) which serves for adjusting the spring element in a radial direction in respect of the centre line (C) and thus to also hold the abutting arrangement (4) in the desired position.
  • a locking mechanism consisting of a locking hook (11) and a locking arm (9) which is loaded by a resiliency so that the locking hook (11) is forcedly moved towards the centre line (C) and placed against the housing of second connector element (2).
  • a locking counter means (10) is arranged at the housing of the second connector element (2) and is located - in the state of mounting depicted in Figure 1a - in insertion direction (E) behind the locking hook (11). Upon further insertion of the first and second connector elements (1, 2), the locking hook (11) of the locking arm (9) can engage with the locking counter means (10) and thus, lock the connector elements (1, 2).
  • the connector elements (1, 2) can be moved together without almost any interaction and expenditure of force until the zero of operation point of the insertion obstruction device (3) is reached (Stroke: 0 mm; Figure 1b) at which the abutting surface (6) of the abutting arrangement (4) contacts the supporting counter surface (5) of the second connector element (2) ( Figure 1a). In this state, no sealing components (14) or contact elements (12, 13) are in mesh and thus, no mating friction occurs.
  • the abutting arrangement (4) of the insertion obstruction device (3) is held in position by the spring element (8), which is abutting against the spring stop unit (18) of the inner sleeve (16) of the first connector element (1), in such way that the abutting surface (6) of the abutting arrangement (4) is aligned so as to abut against the supporting counter surface (5) of the housing of the second connector element (2) in a predetermined way.
  • the abutting surface (6) of the abutting arrangement (4) is pushed against the supporting counter surface (5), and the free arm of the U-shaped structural spring element (8) is loaded with a force in the direction of the free arm of the spring element (8) by which the spring element (8) is deformed and bent up in its curved region.
  • an ejecting force which is orientated opposite to the insertion direction (E) can be generated and the free arm of the spring element (8) is slightly tilted in relation to its original position.
  • the abutting arrangement (4) is - at its end opposite to the insertion direction (E) - slightly tilted away from the centre line (C).
  • Figure 2 shows the condition in which the abutting arrangement (4) contacts in insertion direction (E) both connector elements (1, 2) simultaneously.
  • the spring eye bushing (13) of the first connector element (1) starts contacting the contacting pin (12) of the second connector element (2) and the sealings (14) of the first connector element (1) start meshing with the second connector element (2).
  • the tapered portion (7) of the housing of the first connector element (1) and the tapered portion (19) of the abutting arrangement (4) lie one on top of the other wherein the abutting arrangement (4) is further travelled from its rest position and risen onto the spring stop unit (18) of the spring element (8) of the housing of the first connector element (1) ( Figure 3).
  • the free arm of the spring element (8) archs toward the outside and contacts the outer sleeve (15) of the first connector element (1).
  • the locking hook (11) of the locking arm (9) has risen relatively completely onto the locking counter means (10) in this state and the locking arm has travelled against resiliency from its rest position. In this state the maximum of the ejecting force is reached (Stroke: 3,5 mm, Figure 1b).
  • the tapered portion (7) of the inner sleeve (16), of the first connector element (1) presses against the tapered portion (19) of the abutting arrangement (4) and travels it toward the outside until the abutting surface (6) of the abutting arrangement (4) slides off the supporting counter surface (5) of the second connector element (2) and the spring element (8) is abruptly relieved and the abutting arrangement (4) rises onto the housing of the second connector element (2) ( Figure 4).
  • the maximum of the ejecting force along the insertion path is substantially at least twice as large as the maximum of the sum of all other insertion resistances along the insertion path - except the ejecting force - which are determined substantially by mating friction of sections of the housings of the connector elements (1, 2), friction between the sealings (14) and the contacted surfaces and the spring force and friction related meshing resistances in the contact region of the connector originating from the interaction of spring eye bushing (13) and contact pin (12).
  • the insertion obstruction device (3) is deactivated while inserting both connector elements (1, 2) in the insertion direction (E) prior to occurrence of the maxima of the other individual insertion resistances except the ejecting force and prior to occurrence of the maximum of the sum of the other insertion resistances, except the ejection force.
  • the mounting procedure is stopped by the assembler prior to reaching the final condition of mounting.
  • a damage of the connector elements (1, 2) can be prevented, which might occur in case of exerting an overlarge mounting force, which obviates that the damaged connector elements (1, 2) have to be laboriously replaced.
  • the maxima of frictional force occurring during the insertion path and generating deceptive pressure points are reliably overridden by the exceeding moment of force originating from the sudden deactivation of the insertion obstruction device (3) and thus, an accurate, completed mounting can reliably be achieved.
  • the spring element (8) can be moulded into the housing of the first connector element (1) and thus undetachably be connected with said housing.
  • This variant can prove favourable in respect of manufacturing process and provide an especially reliable and loss-proof connection between the housing of the first connector element (1) and the insertion obstruction device (3).
  • the spring element (8) is arranged to be lockable with the housing of the first connector element (1) and where appropriate, also be detachable from the housing.
  • the spring element (8) for example, can be produced separately and with different characteristics and find application for a whole product line of connectors if these spring elements (8) can retrospectively be connected to the first connector element (1) whereby also production and storage costs can significantly be reduced.
  • springs of different shapes such as plurally-bent leaf spring elements or structural spring elements, spring elements comprising reinforcing corrugations, crimpings or other structures or helical springs which can be attached in different positions of the connector.
  • a construction applying a leaf spring or structural spring or one of the above mentioned embodiments of the spring element provides further constructional opportunities to simultaneously improve a holding and guiding function for the abutting arrangement by said spring element and helps to better define the deactivation behaviour of the insertion obstruction device.
  • deactivation of the insertion obstruction device (3) is conceivable.
  • the deactivation of the insertion obstruction device (3) can also be actuated or supported via a tilting supporting arrangement (7).
  • several housing related structures are conceivable which, for example, can rigidly or movably be attached to the inner sleeves (16) or the outer sleeve (15) of the first connector element (1) and thus, induce or support tilting of the abutting arrangement (4).
  • a supporting counter surface (5) of the housing of the second connector element (2) for example, with an inclined- or rounded-shape or differently-shaped profile which supports the sliding off of the abutting arrangement (4).
  • tapered portions in the contact area of both connector elements (1, 2) so that the abutting arrangement (4) is approximately parallelly dislodged from the centre line (C) and ejected by a sort of " plum kernel effect ".
  • insertion obstruction device (3) On the basis of the aforementioned variations, a variety of possible configurations of insertion obstruction device (3) is conceivable which can be adapted in the best possible way to the mounting requirements.
  • the insertion obstruction device (3) is deactivated prior to the occurrence of the maximum of the sum of the other insertion resistances and prior to locking of the connector elements (1, 2)
  • it is also conceivable to deactivate the insertion obstruction device (3) at a later stage of mounting for example, after overriding the maximum of the sum of the other insertion resistances or after locking of the locking mechanism (9-11).
  • the locking sensation and the locking noise generated by deactivation of the insertion obstruction device (3) reliably signalizes to the assembler that the mounting has accurately been completed.
  • connection system which in case of inaccurate mounting and locking of the locking mechanism, pushes the connector elements apart so that the connection may come undone whereby a fault-proof mounting can be ensured.
  • the point of deactivation of the said device along the insertion path can exactly be set in compliance with the technical requirements.
  • the delusive pressure points can reliably be overridden by the exceeding moment of force, when abruptly deactivating the insertion obstruction device, so that in this way accurate mounting can be secured.
  • the point of deactivation of the insertion obstruction device at a later point of the insertion path or possibly after locking of the connector elements so that, in any circumstance, the connection becomes undone unless insertion and locking of the connector elements is thoroughly completed.
  • the load peak generated by the insertion obstruction device versus the insertion stroke of the connector elements relative to one another and in relation to the meshing action of for example electrical contacts of contact pins and contacting counter-structures or for example sealing structures can be phased in accordance with the customers' mating requirements.
  • the locking mechanism is likewise not restricted to the variant described in the previous embodiment.
