Definitions
- the invention relates to an electrical connection of the type specified in the preamble of claim 1.
- cable sets are used whose plug-in parts and socket parts have multiple contact pins or contact sleeves lying next to one another.
- the longitudinal guide elements between the end plate and the housing consist of guide pins which protrude from the end plate and which were displaceable in axial guide chambers of the housing. These guide chambers were created by an elevation in the housing, above each tubular channel, which was used for the insertion of a contact sleeve. This resulted in a relatively high overall height of the plug-in part.
- the resilient tongue was integrally formed on the inside surface of the tubular channel and did not allow any visual control as to whether the contact sleeve had been properly inserted. Faults in the assembly of the components could result.
- the assembly of these components of the known plug-in part was cumbersome and above all not suitable for automation.
- the invention has for its object to develop a reliable electrical connection of the type mentioned in the preamble of claim 1, the components of which can be easily assembled and are accessible to automation of the process.
- This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special meaning.
- Special longitudinal guide elements between the end plate and the housing are avoided because the outer contour of the housing itself already takes over the guiding effects when the cap is displaced longitudinally.
- the assembly of the cap with the housing can be carried out conveniently without laborious alignment of individual longitudinal guide elements; the cap only needs to be put over the housing like a cover. This allows automatic assembly.
- the attached cap also covers the housing and provides additional protection.
- This covering of the housing by the cap allows the resilient tongue to be produced in a particularly simple manner, namely by wall parts of the tube wall of the housing itself.
- the tongue is therefore clearly visible from the outside in the housing, which also applies in the extended position of the cap.
- the cap can be moved into the final insertion position on the housing, where it covers the tongue and therefore prevents the tongue from unintentionally springing out. In this cover position, the cap locks the contact sleeve inserted into the housing in the correct mounting position; thus serves as a locking means for the assembled contact sleeve.
- the final electrical control of the finished plug-in part ensures that all components are in the correct mounting position if successful. Incorrect results are excluded.
- FIG. 1 in large enlargement and in longitudinal section the plug part of the connection according to the invention at the beginning of the assembly of a Contact sleeve, the cut II being illustrated in FIG. 5,
- FIG. 5 shows, in half section, a first and a second component of the plug-in part according to the invention, namely a housing with an annular seal,
- FIG. 6 shows a fragment of the housing from FIG. 5, on which a further component of the plug-in part, namely a cap, has been attached,
- Fig. 7 is an end view of the complete plug-in part according to the invention.
- Fig. 8 in a longitudinal section corresponding to Fig. 4, the coupled socket and plug-in parts according to the invention, if a proper visual control was not carried out in the construction phase of Fig. 2 and the contact sleeve wrong, namely in a turning position, in the plug-in part has been installed, but what can now still be determined by an electrical final check using the flow-conducting components.
- the electrical connection according to the invention consists, as can best be seen from FIG. 4, of a plug part 10 and a socket part 40, which can be coupled together in use.
- the uncoupling position of these parts 10, 40 is shown in solid lines in FIG. 4, while the coupling position is illustrated in dash-dot lines.
- the plug-in part 10 has a front section 11 which engages in a receptacle in a receptacle 41 which is complementary to the insertion profile of this section 11.
- the socket part 40 has a contact pin 42 in the receptacle 41, to which, in the plug-in part 10, a contact sleeve 12 is assigned.
- the plug-in part 10 and the socket part 40 can have any number of adjacent contact sleeves 12 or contact pins 42, which will be explained in more detail with reference to FIG. 5, but it is sufficient, based on FIGS. 1 to 4, for installation to describe only one such contact sleeve 12. This would correspond to the theoretically possible smallest construction type of such a plug-in part with only one contact sleeve. It is understood that the invention is directed to plug-in parts with any number of contact sleeves, to which complementary socket parts 40 with a corresponding number of contact pins 41 are then assigned.
- the plug-in part 10 Apart from the number of contact sleeves 12, the plug-in part 10 according to the invention consists of a structural unit with four components, namely the already mentioned contact sleeve 12, a housing 20, an annular seal 35 seated thereon and an end cap 30. These components interlock in their end position shown in FIG. 4, which will be explained in more detail.
- the contact sleeve 12 is formed as a stamped and bent product from sheet metal and, as can be seen from FIG. 1, comprises, in addition to its relevant, sleeve-shaped contact section 13, a connecting section 14 for an electrical conductor 15.
- the contact section 13 has an inclined to the longitudinal direction Shoulder 16, which serves to lock the contact sleeve 12 in the housing 20, to be described in more detail. Furthermore, the contact section 13 has a flag 17 projecting outward beyond the outline of the sleeve.
- the housing 20 consists of at least one, but preferably a plurality of tubular channels 21, each of which has a stepped bore and for an axial plug-in assembly of the associated contact sleeve 12 serve in the direction of arrow 22 of FIG. 1.
- the expanded area of the channel 21 has a circular profile and the narrowed outer area has a rectangular profile.
- Each channel is surrounded by walls, which can be interrelated in some areas. This creates a tube shape that can separate, especially in the narrowed bore area, as shown in FIG. 5. Therefore, the channel 21 will be referred to as "pipe” in the following.
- a lower tube wall 23, as can be seen from FIG. 5, is provided in its end region with longitudinal gaps 24, between which a tongue 25, which can also be seen in FIG.
- the housing 20 is also stepped on its outside, of which a housing shoulder 18 provided in the middle housing zone is to be emphasized, which forms a stop surface for one end of the ring seal 50 already mentioned.
- the ring seal 50 consists of elastomeric material with circumferential radial ribs on its outside and encompasses a circumferential housing zone 38 that can be seen in FIG. 5 and is stepped relative to the tube 21.
- the ring seal 50 is secured to the housing 20, as shown in FIG. 4 is seen, an end flange 35 of the cap 30 already mentioned.
- the cap 30 also has other essential functions.
- the cap 30 is profiled in a U-shape and has an essentially flat, plate-shaped apex wall 31 with at least one through hole 32.
- Each of these through holes 32 is assigned to a tube 21 of the housing 20 and serves in the coupling case, as shown in broken lines in FIG. 4 or FIG. 8, for the entry of the socket-side contact pin 42 into the interior of the housing.
- the cap 30 has a side wall that runs all around here, but which, because of its different design and function of individual wall parts, is identified in the drawings with three reference numerals 33 to 33 ".
- a cap interior 34 is formed, which the outer contour 44 from front section of the house 20 is adapted.
- This outer housing contour 44 also serves as a longitudinal guide element for the cap 50 in order to transfer it between two defined axial positions 30, 30 ', one of which 30 in FIGS. 1 to 3 and 6 and the other 30' in the 4 and 8 are shown.
- the cap 30 is guided on the outer contour 44 of the housing 20 in the sense of the double arrows 39 illustrated in FIGS. 1 and 4 in a longitudinally displaceable manner.
- These two axial positions 30, 30 ' are expediently secured by latching positions, which are advantageously designed in the following way.
- the tube wall which acts as a lateral boundary of the housing, to which the parallel cut for FIG. 1 takes place according to the section line I-I of FIG. 5, has a longitudinal cutout 45 which leads to the front end
- extension position 30 for short below.
- the cap in the other axial position 30 ', on the other hand, as shown in FIG. 4, the cap, as already described, holds the ring seal 50 with its end flange 34 in the pressing position on the housing shoulder 18, which is why this position 30' is hereinafter referred to as "insertion position" should.
- the plug-in part 10 according to the invention is assembled in several steps, as will be explained with reference to FIG. 1.
- the ring seal 50 already described is applied to the housing 20.
- the cap is pushed axially onto the free tube end of the housing 20.
- There is a longitudinal displacement 39 until the first latching projection 37 snaps behind the end web 47, while the second latching projections 36, which are provided here twice, come to rest in front of the front end 46 of the housing tube 21.
- the extended position 30 of the cap is thus determined.
- the cap 30 is captively connected to the housing 20 and can be delivered as a structural unit in this preassembled position.
- the cap can now be pushed further out of its extended position 30 from FIG. 3 in the sense of the displacement arrow 39, against the housing zone 38 provided with the ring seal 50.
- the front latching projections 36 move from the side wall region 33 'of the cap over the end web 47 of the cap side wall part 33' and come to rest inside the length cutout 45 shown in FIG. 1 on the inner web edge 53 shown there.
- the side wall parts 33 of the cap lying beyond the window 49 are located above the free end of the tongue 25.
- the tongue end is covered by the cap side wall part 33, which is why one Radial pivoting 48 of the cap 30 'in the direction of the arrow of FIG. 2 is excluded.
- the cap In the inserted position 30 ', the cap surrounds the outer contour 44 of the housing tube 21 or a plurality of tubes lying next to one another on all sides. Disassembly of the contact sleeve 12 in the sense of the arrow 22 'indicated in FIG. 4 is excluded; the contact sleeve 12 is locked with its shoulder 16 behind the step 27 of the ramp 26. The contact sleeve 12 is thus properly locked in its final assembly position in the housing 20 of the plug-in part 10.
- the plug-in part 10 can now be coupled to the socket part 40, which is illustrated in FIG. 4 by the dash-dotted representation 40 'of the socket part.
- the plug-in part 10 comes with its front section 11 mentioned in the introduction to lie in the receptacle 41 of the coupled socket part 40 '.
- the contact pin passes through the through hole 32 at the front end of the cap in the insertion position 30 'into the coupling position 42, likewise indicated by dash-dotted lines in FIG. 4, inside the contact sleeve 12 and ensures perfect electrical contact there.
- the bushing part 40 has a radially projecting cam 54, which can be seen in FIG. 4 and which, in its coupling position 54 ', also shown in dash-dotted lines in FIG. 4, has an inclined ramp
- Coding means are provided for the torsion-proof assembly of the plug part on the one hand and for the proper coupling of the plug and socket part 10, 40.
- the housing 20, according to FIG. 5, has coding grooves 58 at certain points, which cooperate with complementary coding ribs 59, indicated by dashed lines in FIG. 7, in the interior of the cap 30.
- the coding grooves 58 are, as is apparent from FIG. 5, between adjacent housing tubes 21.
- axial cutouts 60 can be provided, which ensure a proper, non-rotatable coupling of the Ensure plug-in part 10 with the socket part 40.
- Complementary axial webs or axial pins not shown in detail, of the receptacle 41 of the bushing are provided, which in the coupling case 40 ′ of the bushing enter these axial recesses 60.
- FIG. 8 illustrates the coupling case between a plug-in part 10 and a socket part 40 ', where, contrary to the preceding description, the contact sleeve 12' shown has been inadvertently inserted in the plug-in part 10 in a rotated position.
- the contact sleeve 12 ' is inserted rotated by 180 relative to the desired case, the radially projecting lug 17 points against the lower tube wall 23 and not, as in the correct position from FIGS. 1 to 4, against the upper tube wall 28.
- the flag 17 can also not enter the longitudinal slot 29 located in the upper tube wall 28, but instead abuts, at the transition point between the wide and narrow bore region of the housing tube 21 mentioned at the beginning, against a shoulder surface 61, which the further plug-in assembly 22 of the contact sleeve 12 'stops.
- the full installation depth of the contact sleeve 12 ' cannot be achieved in the case of FIG. 8 due to the stop action between the flag 17 and the shoulder surface 61 of the housing 20.
- This can be seen from the coupling position 40 'of the socket part in FIG. 8, where the engaged contact pin 42' comes to lie at an axial distance 51 in front of the front end of the incorrectly mounted contact sleeve 12 '. There is therefore no electrical contact.
- the contact gap 51 can be unambiguously concluded from a voltage applied via electrical devices between the incorrectly installed contact sleeve 12 ′ and the coupled contact pin 42 ′, which does not trigger a current flow. As far as one finds the wrong assembly of the plug part 10 and can eliminate this error.
- window in 33 ring seal on 20 axial spacing between 12 'and 42' window reveal of 49 inner web edge of 47 cams at 40 (decoupling position) coupling position of 54
- bracket opening of 57 (Fig. 4, 8) inclined ramp of 57 bracket on 40 coding groove of 20 coding ribs of 30 axial recess in 20 heel area in 23 (Fig. 8)
