Definitions
- the invention is based on an electrical plug connection according to the preamble of claim 1.
- a plug connection is known from DE 35 40 831 C2.
- the connector described therein consists of a first one and a second housing part.
- a hollow cylindrical one Sealing body on a cylindrical part in one of the is arranged in both housing parts, has lips different diameters in alternating order on.
- the larger lips overlap the bush-shaped ones Insertion section of one of the housing parts.
- these sealing lips arc when coupling the connector deflected in the axial direction.
- the little lips limit that available space for the bent Sealing lips, and have no sealing function. After reaching The housing parts are locked in their end position.
- the sealing body also sealing lips has different diameters. Both the non-stop conical formation of the insertion area of the first Housing part as well as the corresponding arrangement of the Sealing lips cause when the plug connection is brought together a strong compression of all sealing lips between the Housing parts.
- the sealing principle used there Compression seal is very forceful, so that there is a correspondingly high force component in the insertion force reflected. In this aspect of optimizing the The type of sealing is unsatisfactory.
- DE-AS 25 55 147 describes a connector its sealing between the housing parts essentially also done according to the above principle.
- On is hollow cylindrical sealing body with three radial sealing lips on a cylindrical partial body of a housing part attached.
- the outside diameter of the three sealing lips is larger than the inside diameter of a bush-shaped housing part, so that the lips of the sealing body when pushing the Housing parts are deflected in an arc in the axial direction.
- the connector is coupled, the air is compressed and escapes along the inner walls of the socket-shaped Housing part and the outer ends of the sealing lips, so that through it and through the oversized lips of the The course of the arc is created.
- a locking of the housing parts does not occur because of the adhesive properties of the rubber and the bent sealing lips no unintentional decoupling allow.
- the separation forces increase with the number of Sealing lips.
- one Sealing body to create a gas-tight connection between to arrange a high-voltage cable and a housing part.
- the sealing body To the assembly of the cable end with the sealing body, it is in the Housing part inserted and rear with a metal sleeve secured.
- a cable intake opening runs in the housing part tapered to be easily interlocked with the beveled to enable trained sealing body.
- Three outside on the Sealing bodies arranged sealing lips are according to the bevel trained with decreasing diameter.
- the metal sleeve causes among other things, that the sealing lips in the insertion opening be compressed and thus ensure tightness.
- a cylindrical housing part is under Intermediate layer of a seal in a socket-shaped housing part arranged.
- the seal encloses the cylinder and is the same as the cylinder itself is slanted in the direction of insertion.
- the socket-shaped housing part has one for this purpose complementary form.
- the sealing body is inside and outside walls molded with compressible lips that are adequate Ensure sealing and at the same time centering problems reduce.
- the connectors mentioned show the basic ones Principles for sealing housing parts using a Lips formed sealing body. Depending on the degree the oversizing of the sealing lip diameter in relation to the inside diameter of the socket-shaped housing part becomes one Deflection of the sealing lip in the axial direction as Lamellar seal understood while squeezing the Sealing lip in the radial direction known as a compression seal is.
- the invention is therefore based on the object Plug connection according to the preamble of claim 1 design that it is liquid-tight and their Housing parts inserted into each other with little effort and can be pulled apart.
- the Housing parts are differentiated by two ring fins Diameter protected from liquid ingress.
- the minor Number of slats and the combination of a slat seal and a compression seal enable low-friction Sealing.
- the short path on which the Ring fins come into contact with the housing wall a good one Pressure equalization guaranteed, so that only slight in this regard Forces must be used. This measure also has an effect positive when disconnecting the connector.
- the Housing parts can be easily separated from each other because the Pressure difference is extremely small.
- the insertion force is significant according to the invention lowered that the design of the housing parts is chosen so that the force components do not add up but occur in succession and as a result almost constant effort over the entire displacement arises at a low level.
- the insertion of the contact parts and the start of the Housing locking is a constant for the further displacement of the contact parts but less contact force is required.
- the maximum of arises for the housing locking force to be used is a constant for the further displacement of the contact parts but less contact force is required.
- the End locking virtually automatically based on the preload, so that the then occurring frictional forces for the sealing that do not increase the entire power level.
- the relaxation of the Latching means and the one taking place at the same time Sealing process compensate for each other Expenditure of energy.
- the latching means relax, the first becomes Housing part in the final position in the second housing part postponed.
- the latching means always exist from a beveled projection on both sides, which with a z. B. arranged on an arm of the other housing part opening interacts.
- the relaxation takes place after the Deflection maximum of the arm, which is then fed by the first housing part in the second housing part along the sloping slope slides.
- the seal can only be found on this short part of the Displacement instead.
- the material for the sealing body especially for the Ring blades, must have good sealing properties and good Have lubricity. These conflicting demands fulfills silicone best.
- the difference between the lamella diameters is advantageously in the range around 1 mm and is dependent on the Angular position of the insertion section.
- This introductory section is kept as short as possible with regard to the assembly path, so the force components for the seal placement only over one short distance of insertion takes effect. As a result these components are optimally integrated into the force curve, to maintain an overall low level of strength. Under this Aspect, it is particularly advantageous the insertion section to graduate. Each slat has its own special area of effect and therefore only causes the absolutely necessary Effort.
- Figures 1, 2 and 4 represent a connector 1 in one Scale of 2.5: 1, while in Figures 3 and 5 a Scale of 5: 1 is realized.
- the electrical Plug connection 1 consists of a first housing part 2 and a second housing part 3.
- the tip 5 in one Socket area 6 protrudes.
- This socket area 6 is used for Inclusion of the second housing part 3 and is for this purpose a specially designed insertion section 7.
- the second housing part 3 consists of a cylinder part 8, in which a contact part 9 is arranged, and from a Cylinder part 8 surrounding housing jacket 10.
- a hollow cylindrical sealing body 11 is pushed on and attached, the outside with three ring blades 12, 13 and 14th is formed, the central ring lamella 13 a has a larger diameter D1 than the two outer ones of the same size Ring blades 12 and 14 with the diameter D2.
- the third ring lamella 14 is also used with a small diameter D2 exclusively creating a symmetrical Slat structure to enable side-neutral installation.
- An opening 15 in the housing jacket 10 and an opening 16 in a deflectable arm 17 work when plugging the two housing parts 2 and 3 with bevelled on both sides Projections 18 and 19 on a housing wall 20 of the first Housing part 2 together.
- the second housing part 3 is so far in the first Housing part 2 introduced that the cylinder part 8 in the Socket area 6 protrudes and the housing jacket 10 or Bump arm 17 against projections 18 and 19.
- the contact parts 4 and 9 don't touch yet.
- the previous one to be used Force is used only to overcome sliding friction between the housing jacket 10 or the arm 17 and the Housing wall 20.
- the second is in the position according to FIGS. 2 and 3 Housing part 3 pushed further into the first housing part 2.
- the tip 5 of the contact part 4 is already in the contact part 9 introduced and thus has the forceful insertion movement completed.
- the housing jacket 10 and the arm 17 were through the tapered projections 18 and 19 deflected to the maximum. If you consider this movement process under purely force Aspect, so two increasing force components add up, from which the contacting force of the contact parts 4 and 9 drops and remains at an even level while the Locking force has risen sharply.
- the sealing body 11 has at this point for the first time a point of contact with the first housing part 2, but does not go into the balance of forces on.
- Figures 4 and 5 show the two housing parts 2 and 3 in their final position, d. H. the connector is complete manufactured.
- the projections 18 and 19 lie in the openings 15 and 16 and lock the housing parts 2 and 3.
- the contact part 4 is fully inserted into the contact part 9.
- the Sealing body 11 lies between the cylinder part 8 and the Housing wall 20 and prevents the entry of liquid between the housing parts 2 and 3.
- the second housing part 3 completely into the first housing part 2 inserted, the arm 17 and the housing jacket 10 under With the help of the bevelled projections 18 and 19 by the restoring forces come to rest almost automatically.
- the ring blades 12 and 13 of the sealing body 11 for the first time with the rotating one Insertion section 7 in the socket area 6 of the first Housing part 2 in contact.
- the insertion section 7 is graduated. Between two stages 21 and 23 there is a slope 22.
- the first stage 21 enables easy advancement of the sealing body 11 and thus of the second housing part 3, since the diameter D3 of the first Step 21 is equal to the diameter D1 of the middle ring lamella 13 is while the front ring lamella 12 is in contact with the Sloping 22 advances and slightly deformed.
- the middle ring lamella 13 at the first stage 21 along the slope 22 and becomes arcuate deflected opposite to the direction of insertion.
- the front one Ring lamella 12 goes from the slopes 22 to the second stage 23 about.
- the diameter D4 of the step 23 is smaller than that Diameter D2 of the ring lamella 12.
- the ring lamella 12 is there consequently highly compressed.
- FIGS. 6 and 7 The difference between FIGS. 6 and 7 is shown in FIGS Power components of a conventional connector with Lamellar seal and a plug connection according to the invention 1 seen. Comparable power components are included the same letters, but they are Power components of the conventional connector additionally provided with an apostrophe.
- the course of the Contacting forces A and A 'between the contact parts is at two plug connections over the entire displacement path S equal. Rise while the contact parts are being brought together the contacting forces A and A 'strongly and then stand out a consistently low level.
- the sealing force B ' the conventional connector sets before Contacting force A 'and increases steadily. This adds up from half of the displacement path S the locking force C ', see above the result is a strongly increasing insertion force D ', that only immediately before the end position of the connector due to the relaxation of elastic locking means.
