Description

The invention relates to a plastic sealing sleeve for a conductor connection according to the features of the preamble of claim 1.

Plastic sealing sleeves of the type in question are known. These are used in particular for moisture-tight coverage of an electrical connection, for example in the automotive sector. Thus, in this context, such a plastic sealing sheath is known in a connection of a first conductor to a starter battery of a motor vehicle.

The plastic sealing cover covers in the use state the connection area and should in particular prevent moisture from penetrating into the, for the purpose of electrical connection end stripped conductor.

From the WO 2008/006477 A1 is known for a ladder connection to a second conductor designed electrical conductor, which has a redesigned application of heat and force and with the aid of a previously applied copper sleeve flat part connection area. This flat part connection area is passed leaving an opening for a penetrating mandrel with an insulation, which also engages over the surrounding insulation of the electrical conductor as such. A comparable insulation of such an electrical conductor is also from the US 5,620,338 A known. From the US 4,126,367 A is an electrical conductor connection between a first and a second conductor known, wherein the conductor is covered by a shoe part on the upper side.

From the US 5,346,408A is a überstreifbare sealing sheath known which is relatively rigid. Your end facing away from the connection area is formed at a distance surrounding the first conductor.

Next it is from the US 2009 / 149,069 A1 known to provide a sealing sheath which is formed over the entire length of the second conductor to an outer surface fitting. The comparatively thick-walled sealing sheath requires that a cable lug of a conductor is previously introduced into the barrel-like region of the sheath.

Based on the stated prior art, the invention is concerned with the task of specifying an advantageous plastic sealing sheath for a conductor connection.

This object is achieved in the subject matter of claim 1, wherein it is based on the fact that the sealing sheath has at its end facing away from the connecting region a tapering section and that the free end of the tapering section is formed to circumferentially lip-like contact on the surface of a cable sheath of the first conductor ,

The end of the first conductor, which is generally stripped off for the purpose of electrical connection, can be completely surrounded by the proposed sealing envelope, with the exception of a region which has the passage opening for producing the electrical connection. The shell-side receiving region can in this case surround the region of the first conductor which has the passage opening of the first conductor, if appropriate, as well as preferably, for completely enclosing the same. In cooperation with the circumferential sealing lip, which surrounds the passage opening in particular the second opening edge, a secure seal against ingress of Moisture can be reached from the outside in the electrical conductor. The sealing lip is preferably only in the course of a conventional determination of the first conductor to the second conductor using the mandrel to effect.

In the area of the further (first) opening edge of the passage opening, a separate seal can be provided. For example, this opening edge may be overlapped like a lid. Such a cover, for example. Hinged lid, is preferably brought into a position sealing the conductor connection to the sealing casing.

The region of the further, in particular the first opening edge, can otherwise be sealed off separately, for example by spraying the opening with an electrically insulating compound, for example further with a grease or an adhesive, in particular hotmelt adhesive or 2-component adhesive.

In any case, as also preferred, a bilaterally encapsulated region may be present.

This can be achieved in a further possible embodiment by forming two, each associated with an opening edge, peripherally closed sealing lips.

The sealing sheath can be designed so that it can be mounted after the establishment of the electrical connection between the first and second conductor and can also be correspondingly preferably disassembled without destroying it.

Another sealing region is provided in the end region of the sealing casing facing away from the connecting region, which also cooperates with the first conductor. This sealing interaction is preferably independent from an electrical connection of the first conductor to the second conductor, for example according to a screw connection.

The elastically resilient material may in particular be a thermoplastic material or rubber, further for example also silicone rubber. More preferably, the sealing sheath or the material used for this purpose may have a modulus of elasticity which is less than 5 kN / mm ² , more preferably less than 3.3 kN / mm ² .

The tapered portion formed for sealing engagement with the first conductor at the end remote from the connection portion may start from or away from the connection portion. It may, for example, be conically tapered, with an end-side smallest diameter which is equal to or smaller than the diameter of the first conductor in the contact region of the tapering section.

In addition, the seal can be achieved in this area via a cable gland with PG thread (so-called PG threaded connection), alternatively by a clamping ring in the manner of a hose clamp, which is pulled over the end portion of the sealing sheath. Furthermore, it is possible in this regard to insert a sealing ring, for example an O-ring, or a stuffing box end between the sealing casing and the first conductor.

Also, in a longitudinal direction of the sealing sheath or of the first conductor when the sealing sheath is applied, the upper and / or lower sealing lip may be projected in a front view, in any case in its central region, from a contour of the region adjoining the sealing lips. This adjoining area can be adapted to the configuration of the same formed in the corresponding area of the first conductor. For example, the receiving area with the sealing lips may extend in a plane-offset manner to a plane running parallel to the first conductor and passing essentially centrally through it.

The region projecting beyond the sealing lip may in this case have a height which exceeds the sealing lip and is considered in the direction of penetration, which corresponds to a multiple, for example 5 to 50 times, for example 10 to 30 times the free sealing lip height. The free sealing lip height is in this case preferably measured from a plane in which the sealing lip in the receiving area circumferentially passes to - with respect to a vertical section through the sealing lip - to the free end of the sealing lip, for example, to the zenith of the same.

In the non-mounted state of the sealing sleeve, it may have an opening in the region of the tapering section, this opening having a diameter dimension which is smaller in each direction than a largest dimension of the first conductor in the push-through section. The largest dimension of the first conductor in the through-hole portion may correspond to a multiple, in particular a 1.2 to 2 times, for example, 1.5 times the opening diameter dimension in the taper portion of the sealing sheath.

Preferably, the sealing sheath is applied to the end of the first conductor to be sealed in such a way that initially the push-through section of the first conductor is guided through the opening in the region of the optionally provided narrowing section of the sealing sheath. As a result of the elastically resilient configuration of the entire sealing sheath, the tapering section can be formed in the course of putting the sealing sheath onto the first conductor in the course of the penetration of the push-through section through the tapering section according to which provision can be sealingly cooperated with the corresponding section of the first conductor. This results in an automatic system of the edge surrounding the opening to the associated region of the first conductor.

The sealing sheath can have a length which corresponds to 2 or more times, preferably up to 10 times the free diameter of an insertion opening of the first conductor. The insertion opening of the first conductor is exposed with plugged sealing sheath, surrounded by the receiving area, for electrical connection in the region of the shell-side through hole. About the insertion opening by means of the mandrel, the electrical connection with the second conductor can be brought.

The shell-side through-opening may have a diameter dimension which corresponds to a multiple of the diameter dimension of the conductor-side insertion opening. Thus, the dimension of the shell-side through-opening can correspond to 2 to 5 times the diameter dimension of the conductor-side through-opening.

In any case, associated with the receiving area, the sealing casing may have the outer contour of a cable lug. Preferably, the electrical conductor is provided on the end with a cable lug, in particular with a lug made of a pipe part. This cable lug establishes an electrical connection to the electrically conductive wires of the first conductor which are enveloped by an insulation. The connection between the cable lug and the wires of the electrical conductor is produced, for example, as a result of crimping or crimping.

In a preferred embodiment, the sealing envelope takes on the overall outer contour of the cable lug of the first conductor.

Preferably, the sealing sheath is designed so that this inner shell at least largely rests against the associated surface of the cable lug and / or the insulating sheath of the electrical conductor. Also, in the connection state, the sealing sheath can partially surround the first conductor at a distance transversely to its longitudinal extent, for example in the area of cable crimping or crimping. Here, with respect to a longitudinal axis of the first conductor, a Radialabstandsmaß between the sealing sheath and the cable lug of 1 to 10 mm result.

The first conductor has an insulating sheath. In the connection state, the taper portion of the sealing sheath and the lip-like edge surrounding the opening in question seal with an outer surface of the sheath. By shortening the tapering section, the resulting opening in the region of the narrowing section can be adjusted in diameter to the outer diameter of the casing, so that even with different cross-sectional dimension of the first conductor in the region of the casing, a sufficient seal can be achieved in the connection state. This can be achieved by a preferred conical design of the tapering section.

The sealing lip may have a free height of 0.5 to 3mm and a thickness across the piercing direction of 0.5 to 3mm.

The sealing lip can also pass radially inward directly into the passage opening of the sealing jacket-side receiving region.

In a further embodiment, the sealing lip can pass in a cross-section in a planar area. This planar area extends outside the outer wall of the sealing sleeve, facing away from the first conductor or the cable lug, and starting from the sealing lip, at least generally radially outward and / or in the longitudinal direction of the sealing sheath.

The planar area may extend beyond the sealing lip at least by the amount of the thickness of the sealing lip up to a ten-fold or more, up to a 50-times the thickness of the sealing lip elevation and / or recess.

The plastic sheath serves for electrical insulation of the connection area. An elastically resilient sealing lip can be used in particular for producing an electrical connection which is sealed against penetration of moisture from the outside.

It can be provided that, in a cross section in which the enforcement direction appears as a line, the conductor element has a first region at a first height level and a second region at a second height level, wherein the first region is farther away from the aperture than the second Area (viewed in the longitudinal direction of the conductor element and / or the connected conductor), the first region is the second region upstream in the through-hole and the sealing lip is formed surrounding the second region, wherein at the area at the higher height level at a distance to the opening can still connect at one or more height levels forming connecting portion and that the sealing lip in the enforcement direction in the undeformed state on the otherwise sealing lip side exposed second portion of the conductor element, but by deformation is zurückdrängbar to a plane wel che forms the bottom of the second area.

The first region of the conductor element is used in particular for electrically conductive connection with the associated conductor. This connection region between the first region of the conductor element and the conductor or its connection region is preferably enveloped by the plastic of the connection part.

The second region of the conductor element extends in the direction of enforcement offset from the first region, moreover preferably serves for the production an electrical connection with the other conductor, moreover, according to the mechanical connection with the other conductor, for example. According to a screw connection.

The offset in the direction of penetration from the second region to the first region of the conductor element preferably corresponds at least to the material thickness of the conductor element, preferably to a multiple of the conductor element thickness up to a tenfold.

The plastic sheath, can be achieved according to encapsulation of the conductor element and the connection portion of the associated electrical conductor with plastic, in particular elastically resilient plastic. Also, the enclosure may be present as a separately manufactured component, which, if necessary, even after production of the electrical connection, is mountable in the connection area. Also, such a sheath may preferably be dismantled non-destructively.

The circumferential sealing lip serves to seal outward against moisture in the connection position. Against the sealing lip acts in the connecting position, a portion of a screw or a bolt, eg. The flat side of a nut or a screw head, in addition, optionally, the flat side of a washer.

It can also be provided that the connecting part has in a cross-sectional view two circumferential sealing lips, which are formed opposite with respect to the direction of enforcement. Thus, in such an embodiment viewed in the direction of enforcement on both sides of the passage opening provided a circumferential sealing lip.

Moreover, a sealing lip may be present in the direction of penetration with respect to the area of the plastic covering surrounding the sealing lips. Thus, a circumferential sealing lip may be formed like a bead, which is elastically deformable due to stress on a screw head or a nut.

The transition between the first and the second height level of the conductor element may be formed stepwise in cross section. Thus, a lowering given thereby can be designed to be rotationally symmetrical with respect to an axis passing through the penetration opening of the conductor element in the second region. The lowering can have a total of a pot-like shape, with a particular for electrical connection exposed pot bottom and a preferably perpendicular to the pot bottom plane pot wall. The conductor element is preferably free in the region of the pot bottom on both sides for electrical contacting. In a further development, in addition, the pot inner wall can be exposed, d. H. not be covered with plastic.

The surrounding plastic may continue opposite to the lowering given by the ladder element at a second height level into a freestanding collar. In this case, the collar can be of annular design overall, with a preferred inner diameter which can correspond to the free inner diameter of the cup-like depression.

The collar may have a circumferential or circumferentially partially circumferential locking lip. This has in a preferred embodiment radially outward.

The locking lip can be used for latching connection with a closure cap A seated in the lowering screw head or the like can be so covered by the sealing cap sealing. Due to the elastically resilient design of the plastic latching the closure cap on the collar, as well as a removal of the cap from the collar preferably without tools by the user can be brought.

The cap can be present as a loose part. In a preferred embodiment, the closure cap is formed integrally with the plastic wrapper via a bendable extension. The bendable extension can be designed in the form of a strip of tape which, while retaining the connection of the closure cap to the plastic covering, allows it to be placed on or removed from the collar.

In a further embodiment, the conductor element may be part of a cable lug.

One possible embodiment provides that the sealing lip is part of a folding or plug-in housing which can be applied to the conductor element.

Shown and described, first with reference to FIG. 1 , a first electrical conductor 1, which essentially consists of a cable 4 and a cable lug 5.

The cable 4 has a sheath 2 for electrically conductive wires 3. The cross section of the cable 4 is preferably circular.

The freed from the sheath 2 free end of the cable 4 is connected to the cable lug 5. For this purpose, the wires 3 engage in a tubular crimping section 6 of the cable lug 5. In this section, to provide the electrical conductivity, as well as the definition of the cable lug 5, a compression provided. The corresponding pressing region 7 is in the sectional view in FIG. 10 to recognize.

Facing away from the cable 4, the cable lug 5 is formed into a flat push-through region 8. This has an at least approximately square ground plan. The push-through region 8 is formed as a result of deformation from the original tubular shape to form the cable lug 5.

The push-through region 8 extends in a plane which extends offset to a parallel plane, which passes through the cable 4 and the crimping section 6 in the middle. It may thus result in a step portion 9 rising obliquely at an angle of approximately 45 ° between the push-through region 8 and the crimping section 6.

The angle here refers to a perpendicular to the push-through area 8.

Furthermore, the push-through region 8 is provided with a preferably circular through-insertion opening 10 in the plan view. This passes through the push-through region 8 in the region of its broad side surfaces, with a diameter d which corresponds approximately to half of a largest dimension a of the push-through region 8.

The first conductor 1 can be assigned to a second electrical conductor 11. The conductive connection results via an electrically conductive mandrel 12, for example by a, as also shown, screw, which mandrel 12 engages through the through opening 10 of the first conductor 1.

In particular, for sealing the free end of the first conductor 1 against moisture penetrating from the outside in the use position, the first conductor 1, a plastic sealing sheath 13 can be assigned.

The sealing sheath 13 is designed to slip over the free, the cable lug 5 having the end of the first conductor 1, this is preferably made of an elastically resilient material, in particular plastic material.

The sealing sheath 13 is initially and substantially tubular-shaped, with a tubular cylinder portion 22, according to the in the FIGS. 2 to 12 shown first end in a tapered section 14, and a substantially flat receiving area 15th

Next, the sealing sheath 13 is formed substantially adapted to the external contour of the cable lug 5. For this purpose, the receiving region 15 preferably has an at least approximately square plan, adapted to the push-through region 8 of the cable lug 5. Also, a step-like transition (step section 16) is provided which connects the receiving region 15 with the cylinder section 22. The receiving area 15 extends in a plane which is offset from a parallel plane passing through the cylinder section 22 in the middle.

The receiving area 15 is designed to be in the connected state, i. when pushed onto the cable lug 5 state, the push-through area 8 almost completely surrounds, this in particular with respect to the free edges and the through-hole 10 surrounding surface areas of the broad side surfaces. The cable shoe-side step portion 9 and its crimping portion 6 are completely enclosed by the shell-side step portion 16 and the cylinder portion 22.

The broad side surfaces of the receiving area 15 are pierced by passage openings 17 whose free diameter d 'corresponds approximately to twice the diameter d of the through opening 10.

In the connection state, the passage openings 17 of the receiving area 15 are preferably aligned at least approximately concentrically to the insertion opening 10 of the cable lug 5.

The passage opening 17 is encompassed by a circumferential sealing lip 18 on each broad side surface. Radially inside, the sealing lip 18 preferably passes directly into the passage opening 17.

Each sealing lip 18 may have a free height h - starting from the facing surface of the receiving area 15 and in the through-direction r - of about 1.5 to 2 mm. The radial thickness c of each sealing lip 18 may be about 2 to 3 mm.

In addition, the sealing lip - with respect to a cross-section (for example in FIG. 10 shown) - go into a planar area. This planar area may be the adjoining connecting area, which extends at least over a length which corresponds at least to 5 or 10 times the sealing lip thickness c, without elevation and / or recessing.

The taper portion 14 tapers conically toward its free end and forms an opening 19 at the end. This is penetrated in the connection state of the cable. 4

The opening 19 has a diameter dimension b, which is chosen smaller than the largest dimension a in Durchsteckbereich 8 of the cable lug fifth

Furthermore, the opening 19 is adapted or adaptable to the outer diameter of the cable sheathing 2. When the tapering section 14 is shortened along a longitudinal axis x of the cylinder section 22, the opening 19 can be enlarged in diameter and thus adaptable to the sheath diameter.

The sealing casing 13 has a length e considered in the extension direction of the axis x, which length may correspond to approximately 8 to 10 times the diameter d of the through opening 10.

The sealing sheath 13 is pushed for shipment in the state of connection with the first conductor 1 with its opening 19 via the cable lug 15 - under appropriate elongation against the elastic restoring force of the taper portion 14 - to a position in which the cable lug-side push-through 8 in the receiving area 15 of the sealing sheath 13 preferably comes to rest.
