Definitions

• the present invention relates to a connector element for an electrical plug type connector, having at least one receiving member which is open at least at one side in an introduction direction for an electrical contact element, the receiving member forming a retention portion.
• the invention further relates to a contact element for an electrical connector element having a retention region for securing the contact element in a receiving member of the connector element.
• the invention further relates to a connector element having at least one receiving member which has a retention portion, in which an electrical contact element which is introduced into the at least one receiving member as far as the end position thereof is retained.
• the contact elements are, for example, inserted in the form of plug contacts into the receiving member or contact receiving member of the connector elements in order often to be retained independently at that location without the use of additional auxiliary means.
• the contact elements are inserted into the receiving member in an insertion direction and arrive with the retention region thereof in the end position generally in a positive-locking and/or non-positive-locking connection with the receiving member.
• Retention elements of the contact element which are formed in the retention region may penetrate, for example, into a wall of the receiving member or plastically and/or resiliency deform the receiving member so that a secure arrangement of the contact elements is ensured.
• the contact elements are generally formed from punched sheet metal material.
• connector elements or the inner space thereof are intended to be hermetically sealed to the greatest possible extent so that harmful substances, such as corrosive fluids and gases, cannot penetrate into the connector element.
• One manner of sealing the inner side of the connector element is, for example, to cast it with hypoxide resin or a thermoplastic plastics material.
• the cast mass can, for example, after the contact elements have been inserted in the receiving member and the contact elements have been connected to electrical conductors in the inner space of the connector element, be injected therein.
• the contact elements and in particular connection locations with respect to the electrical conductors are generally hermetically surrounded.
• the connector element and contact elements which are received therein form, owing to the cast mass, a solid, hermetically sealed component which is robust and resistant with respect to harmful environmental influences.
• a problem when sealing inner spaces of connector elements according to the prior art is that the cast mass can penetrate through gaps or capillaries formed between the walls of the receiving members and the contact elements as far as an insertion face of the connector elements, which face is constructed to be able to be connected to a mating connector element.
• the cast mass which has penetrated into the insertion face may remain in the insertion face after hardening and contaminate the insertion regions of the contact elements at that location and/or change a contour of the insertion face. The contamination may bring about occurrences of incorrect contacting of the contact elements with counter-contact elements which are arranged in a mating connector element or impair correct electrical contact.
• the contour change may lead to the connector element no longer being able to be correctly connected to a mating connector element since the insertion face can no longer engage with a complementarily formed mating insertion face of the mating connector element and consequently a plug type connector comprising the connector element and mating connector element may potentially no longer be able to be moved into a correct end insertion position.
• an object of the present invention is to provide a sealable or castable connector element in which a cast mass cannot reach the insertion face from the inner space via the receiving members for the contacts or the inner space can be protected against harmful environmental influences to the best possible extent.
• a connector element for an electrical plug connector may be provided with at least one receiving member for an electrical contact element which can be introduced into the receiving member as far as an end position, the receiving member having a retention portion which is constructed to retain the contact element in the end position thereof.
• the receiving member may have a resiliently deformable sealing portion which is constructed to surround the contact element in a sealing manner at least in the end position at the outer peripheral side.
• the object is solved by a sealing region which is constructed to be at least partially surrounded in a sealing manner by the receiving member.
• the object is achieved in that the at least one receiving member has a sealing portion in which the contact element at least partially widens the at least one receiving member and is surrounded in a sealing manner by the at least one receiving member.
• the solutions according to the invention have the advantage that the receiving member can resiliently engage around the contact element in the manner of a collar and gaps or capillaries between the walls of the receiving member and the contact element are closed, whereas the retention portion can be reliably retained in a non-displaceable manner by means of a positive-locking, non-positive-locking and/or frictional engagement owing to the increased rigidity thereof with respect to the sealing portion.
• the solutions according to the invention may allow the receiving member, when the contact element is inserted, or at the latest when the end position of the contact element is reached, to cooperate in a sealing manner with the contact element and consequently to prevent cast mass from the inner space of the connector element between the contact element and the walls of the receiving member from being able to reach the insertion face.
• the sealing portion may, for example, be offset from the retention portion so that the sealing portion can be configured to perform a sealing function and the retention portion may be configured to perform a retention function.
• a connector element when viewed in an insertion direction for connection of the connector element to a mating connector element, to be arranged upstream of the retention portion. That is to say, the sealing portion may be constructed as an adjacent portion of the receiving member. The sealing portion can thus engage round the contact element in the manner of a collar and cooperate with the contact element in a sealing manner in a state as close as possible to an opening leading to the receiving member facing the inner space. Consequently, a cast mass on the sealing portion may already be prevented from penetrating between the walls and receiving member of the contact elements.
• a flexibility of the sealing portion may be greater than a flexibility of the retention portion.
• the inner periphery of the sealing portion may thus be increased when the contact element is introduced into the receiving member and thereby fit closely against the outer periphery of the contact element in a sealing manner. That is to say, the sealing portion or the cross-section thereof may be constructed so as to be able to be expanded in the manner of a rubber band in order to allow a tight positive-locking connection between the contact element and sealing portion and consequently independent sealing of the contact receiving member with the contact element received therein.
• a material thickness of a wall of the at least one receiving member on the sealing portion may be smaller than on the retention portion.
• a smaller material thickness of the wall in the sealing region than in the retention portion may bring about increased resilience of the sealing portion with respect to the retention portion. Consequently, the sealing portion can perform the sealing function in an effective manner, whilst the retention portion owing to lower resilience than the retention portion can retain the contact element in the end position in the most rigid and secure manner possible.
• An outer edge of a contact receiving member of the connector element which forms the at least one receiving member may be at least partially provided with a chamfer at least in the region of the sealing portion.
• the contact receiving member may, for example, protrude as a type of nozzle or sleeve-like continuation from a base of the insertion face in the insertion direction.
• the chamfer at the outer edge of the contact receiving member may result, in particular in the region of the sealing portion, in the provision of a material thickness of the wall of the receiving member which promotes resilient expansion and close fitting of the receiving member against the contact element.
• the at least one receiving member may taper in a concave manner and/or expand in a convex manner at least partially in a projection along a longitudinal axis of the at least one receiving member. That is to say, the receiving member may be slightly narrowed or expanded in a plan view or in a view therethrough. With contact elements which have a size in the millimetre range, this narrowing or expansion may have a radius which is, for example, between 100 mm and 150 mm, that is to say, of relatively large dimensions. The radius may preferably be between 120 mm and 140 mm. A radius of a curvature of the wall of the receiving member formed by means of expansion or narrowing may be 130 mm according to one embodiment.
• the receiving member when viewed in the longitudinal direction thereof, may, for example, have a width which is substantially smaller than the length thereof, a depth of the receiving member being able to be dimensioned parallel with the longitudinal direction.
• the radius may, for example, be provided in a region of the wall thereof extending in the longitudinal direction of the receiving member.
• An inner periphery of the sealing portion may be at least partially larger than an inner periphery of the retention portion. Consequently, on the one hand, the thickness of the wall of the contact receiving element may be reduced in the region of the sealing portion in order to increase the flexibility of the sealing portion and its tendency to fit closely against the contact element. Furthermore, an increased inner periphery of the sealing portion with respect to the retention portion may bring about greater flexibility of the sealing portion with respect to the retention portion since the sealing portion may have a larger surface than the retention portion. Between the sealing portion and the retention portion, a shoulder may be formed in order to delimit the function of the sealing portion clearly from that of the retention portion.
• the solution according to the invention may be further improved in that the sealing region has at least one sealing projection, which protrudes substantially transversely relative to an introduction direction for introducing the contact element into the receiving member on the contact element.
• the sealing projection may help to expand the sealing portion of the receiving member and to ensure a tight abutment of the inner contour of the receiving member against the sealing region.

• the receiving member 15, 15' may be subdivided into a retention portion 16 and a sealing portion 17, 17' of any shape and length, the sealing portion being able to be constructed for sealing between the inner contour 14a, 14a' and the contact element 100 and the retention portion 16 being able to be constructed for securing the contact element 100 in the receiving member 15, 15', but with both portions also being able to perform a dual function.
• chamfers 19 and inclined entry members 19a on the contact receiving member 6, 6' in order to facilitate the introduction of the contact element 100 into the receiving member 15, 15', or the expansion and/or deformation thereof. It is advantageous to construct longitudinal walls 15d, 15d' to be longer than transverse walls 15c, 15c' of the receiving member 15, 15' so that, owing to an expansion in the lateral direction X, a close abutment of the longitudinal walls 15d, 15d' against the lateral faces 107 of the contact element 100 can be brought about. Owing to this operation, the gap 22 between the contact element 100 and the inner contour 14a, 14a' of the receiving member 15, 15' may be closed and consequently sealed between the contact element 100 and the receiving member 15, 15'.
• sealing portion 17, 17' may be divided into upper sealing portions 17a and lower sealing portions 17b, for example, by means of shoulders 21 .
• Tension zones 23 are not necessarily limited to the longitudinal walls 15d, 15d' of the contact receiving member 6, 6' but instead may be formed on the transverse walls 15c, 15c' of the contact receiving member 6, 6'.
• the contact element 100 may further be provided with insertion regions 101 , retention regions 102, sealing regions 103 and connection regions 104 which are constructed in accordance with the respective requirements and which may form upper retention projections 102a, lower retention projections 102b and sealing projections 103a, which extend away from a channel 105 in order to be brought into engagement with the inner contour 14a, 14a' of the receiving member 15, 15'.
• the upper and lower retention projections 102a, 102b and sealing projections 103a may be constructed, as shown here, as projections, or alternatively as hooks, teeth or other protrusions.
• the contact element 100 may be provided with shoulders 106 and corresponding stops 106a of any shape and arrangement in order to ensure that the end position E is reached.
• the lateral faces 107 may be constructed in accordance with the respective requirements in order to facilitate sealing between the receiving member 15, 15' and the contact element 100.
• the insertion direction P, counter-insertion direction P', introduction direction I, longitudinal axes L 6 , L 15 , L 100 , radii R, lateral direction X, transverse direction Y and vertical direction Z may be selected in accordance with the respective requirements in order to form a connector element 1 , 1 ' so as to be able to be connected to a mating connector element and in the most complementary manner possible, and to enable introduction of one of the contact elements 100 into the receiving member 15, 15'.
• the width bis, b 15 , length l 15 , l 15 may be selected in accordance with the respective requirements in order to form a connector element 1 , 1 ' so as to be able to be connected to a mating connector element and in the most complementary manner possible, and to enable introduction of one of the contact elements 100 into the receiving member 15, 15'.
