Abstract
Description
Technical Field
[0001] This invention relates to a cable retainer insert for multi-strand cables, the cable retainer being configured to insert into the housing of a connector. The invention also relates to a connector. Background Technology
[0002] In existing technologies, multi-strand cables combine shielded and unshielded strands within a single cable. Such cables can be used for power transmission combined with data transmission. However, in existing solutions, the protective grounding connection and shielding implementation via a metal housing are cumbersome, making the connector housings for terminating multi-strand cables non-universal. Summary of the Invention
[0003] One aspect of the present invention is an improvement on existing technical solutions for cable retainer inserts and connectors receiving such cable retainer inserts, in view of the provided shielding transfer and its versatility.
[0004] The cable retainer plug of the present invention has a cable contact portion and a plurality of circumferentially spaced cable receptacles, each cable receptacle being configured to receive at least one strand of a multi-strand cable, each cable receptacle also including a cable strand insertion opening at a radially outer end and a bottom at an opposite radially inner end, wherein a circle inscribed in the cable receptacle and contacting the bottom of the cable receptacle extends radially outward beyond the cable strand insertion opening.
[0005] The connector according to the invention includes a connector housing configured to receive a cable retainer insert, as described above, a cable having an outer shield, and a plurality of cable strands having strand shields, wherein a cable contact portion is inserted into the outer shield, and at least one of the plurality of cable strands is inserted into a cable receiving portion, wherein the cable retainer insert is electrically contacted by the strand shields of the cable strands in the cable receiving portion, and wherein the outer shield is arranged between a cable strand insertion opening and a clamping mechanism extending circumferentially across the cable retainer insert.
[0006] The cable retainer insert and connector according to the invention have the following advantages: both the unshielded strands (e.g., protective grounding strands) and shielded strands of a multi-strand cable can be securely received and held within the corresponding cable receptacle. The strands or their shields can then be reliably electrically contacted. The circle inscribed within the cable receptacle represents the cable diameter of the cable fully inserted into the receptacle. When the circle protrudes from the cable receptacle, the cable also protrudes. This facilitates friction and clamping of the cable within the cable retainer insert.
[0007] Further advantageous embodiments of the invention will be described below. These embodiments include additional technical features that can be arbitrarily combined with each other or omitted—if the technical effect obtained by omitting the technical features is not essential to the invention. The embodiments described below are exemplary and do not limit the invention.
[0008] The connector of this invention can be a connector housing for terminating wires. It is particularly applicable to the agricultural sector, specifically connectors conforming to the Agricultural Industry Electronic Foundation (AEF) standard. It can be used to provide connections between tractors and implements such as tow trailers or tractors. An advantage of the connector of this invention is that the entire cable shield of a multi-strand cable, or the shield of each strand of a multi-strand cable, is reliably transferred to the connector, thereby providing a continuous 360° shield for each shielded cable.
[0009] The cable retainer plug and connector of this invention can be applied in various technical fields requiring reliable shielding transfer. This invention is particularly applicable to the agricultural sector, especially for interconnected electrical equipment.
[0010] A multi-strand cable may comprise different strands with different functions. For example, it may include power strands for transmitting current or electricity, data strands for transmitting data signals, and protective grounding strands. Each strand may have its own shield. Any number of these strands may be present. Furthermore, the multi-strand cable may include an external shield surrounding all the strands of the multi-strand cable. This continuous 360° shield will be transferred and held by the connector of this invention.
[0011] Each strand of a multi-strand cable may have a loop surrounding the corresponding strand. The loop may further include an outer contact loop comprising a spring wire or a sheet, wherein each spring wire or sheet can be deflected relative to the radial direction and provide an individual contact point. The outer contact loop can therefore include multiple circumferentially arranged contact points.
[0012] The strand shield can be electrically connected to the ferrule via electromagnetic pulse (EMP) technology. This refers to a method of joining dissimilar materials together using an electromagnetic pulse, which accelerates the different parts to be joined together via a strong electromagnetic field. The parts are accelerated in opposite directions, whereby the two parts bond material-to-material. However, the strand shield can be electrically connected to the ferrule, and the ferrule can be electrically connected to the cable retainer insert, in any suitable manner.
[0013] The cable contact portion of the cable retainer insert may have a circular outer contour, wherein the circle may be interrupted by an insertion opening (at least one insertion opening) of the cable receiving portion. The cable receiving portion may be formed as an axially extending groove and open at both axial ends of the cable retainer insert.
[0014] A cable retainer insert may include a plug end face and a cable end face, both facing axially, and an outer contour extending circumferentially between the two end faces. The end faces may be positioned parallel to each other and offset in the axial direction, wherein a cable receiving portion extends from the plug end face to the cable end face. The cable receiving portion may open to the outer contour of the cable retainer insert. They can therefore be open in a radial direction perpendicular to the axial orientation.
[0015] The cable strand insertion opening may be an opening through which the cable strands can be inserted into the cable receiver of the cable retainer plug. The bottom of the cable receiver may be arched, or semi-circular in cross-section perpendicular to the axial direction.
[0016] The inscribed circle or inner circle within the cable receptacle is the largest circle contained within the cable receptacle and contacting its bottom. Such an inscribed circle contacts the cable receptacle at at least three points. The inscribed circle extends radially outward beyond the cable strand insertion opening. The inscribed circle may also extend beyond the circumscribed circle or outer circle of the cable contact portion.
[0017] The cable retainer insert can be further improved because it is conductive. The advantage of this is that it allows each shield to make mechanical and thus electrical contact with the cable retainer insert, thereby ensuring that each shield reaches a common potential.
[0018] The cable retainer plug-in of the present invention may further comprise at least two cable retainer plug-in modules positioned adjacent to each other in the circumferential direction. An advantage of this embodiment is that the cable retainer plug-in can be flexible during assembly, and by means of a cable retainer plug-in comprising at least two cable retainer plug-in modules, virtually any number of possible combinations of strands with different numbers and / or sizes can be reliably retained and contacted. The cable retainer plug-in modules can thus form the cable retainer plug-in. If two cable retainer plug-in modules are included, their shape may resemble a semicircle. If three or more cable retainer plug-in modules are provided, their shape may resemble a sector. A preferred embodiment provides four cable retainer plug-in modules whose shape resembles a sector with a 90° angle. Any other number of cable retainer plug-in modules can be used.
[0019] In another embodiment of the cable retainer plug of the present invention, each cable retainer plug may include at least one cable receiving portion. A plurality of cable receiving portions may be provided in the cable retainer plug module.
[0020] In another embodiment of the cable retainer insert of the present invention, the cable retainer insert may include a housing contact portion for the housing of the electrical contact connector, the diameter of which is smaller than the diameter of the housing contact portion. The advantage of providing a housing contact portion is that contact with the different shields of the multi-strand cable can be functionally separated from the connection to the connector housing. Therefore, contact with the housing does not interfere with setting all shields to a common potential. Thus, continuous 360° shielding is ensured and is not disturbed by any possible erroneous contact between the housing contact portion and the connector housing.
[0021] Since the diameter of the housing contact portion is larger than the diameter of the cable contact portion, the housing contact achieved through the housing contact portion does not change or (adversely) affect the strands of the multi-strand cable that are received and contacted in or through the cable receptacle.
[0022] The at least one cable receptacle may extend through both the cable contact portion and the housing contact portion. The cable contact portion and / or the housing contact portion may have a cylindrical shape. In embodiments where the cable retainer insert includes at least two cable retainer insert modules, those modules may have a cylindrical segment shape. The cylindrical segment may include a cylindrical segment of the cable contact portion and a cylindrical segment of the housing contact portion. Preferably, the cylindrical segments of the cable contact portion and the housing contact portion have the same angle.
[0023] In another embodiment of the cable retainer plug of the present invention, the axial length of the cable contact portion may be greater than the axial length of the housing contact portion. The axial length is measured along the axial direction.
[0024] In the assembled state, the cable contact portion and / or the housing contact portion may correspond to a cylindrical shape, wherein the height of the cylinder may be defined along an axial direction perpendicular to the radial direction. The height of the cylinder describing the cable contact portion may be greater than the height of the cylinder describing the housing contact portion.
[0025] In a preferred embodiment, the cable retainer insert has at least one circumferential groove. The at least one circumferential groove may include a groove bottom facing in the radial direction.
[0026] The bottom of the groove can be located at a third radius, wherein the circle inscribed in the cable receiver can extend beyond this third radius. In this embodiment, edges can be provided on both sides of the groove, wherein these edges are arranged circumferentially and limit the groove in the axial direction and relative to the axial direction. In this embodiment, the inscribed circle extends radially outward beyond the cable strand insertion opening and beyond the third radius. The cable strand insertion opening is located at the radial height of the bottom of the groove. The groove is interrupted in the circumferential direction by the cable strand insertion opening. The cable strand insertion opening is radially recessed inward at the location where the bottom of the groove intersects with the cable receiver.
[0027] This embodiment can be further improved by providing a clamping mechanism configured to insert into a circumferential groove and configured to extend across the cable strand insertion opening in the circumferential direction. Preferably, the circumferential groove is provided at the cable contact portion, and the clamping mechanism is configured to insert into the circumferential groove at the cable contact portion.
[0028] The advantage of this is that the circumferential groove predetermines the position of the clamping mechanism, and once the clamping mechanism is installed on the cable retainer plug, its position is fixed by the circumferential groove.
[0029] This embodiment of the cable retainer insert, when applied in the connector housing, securely fixes the position of the outer shield relative to the cable retainer insert via a clamping mechanism. When the circle inscribed in the cable receptacle extends beyond the bottom of the circumferential groove, the strand or strand shield received in the cable receptacle also extends beyond the cable strand insertion opening at the point where the bottom of the groove intersects with the cable receptacle. The outer shield is moved into the circumferential groove by the clamping mechanism and moves toward the cable strand insertion opening, thereby ensuring reliable electrical contact between the strand and strand shield and the outer shield and the cable retainer insert. Simultaneously, the clamping mechanism presses the outer shield into the circumferential groove between adjacent cable strand insertion openings to abut against the bottom of the circumferential groove.
[0030] The cable strand insertion opening is located at the outer contour of the cable contact portion or at the bottom of the circumferential groove in the cable contact portion. In one embodiment of the cable retainer insert of the present invention, a clamping member may also be provided without the circumferential groove.
[0031] When the clamping mechanism extends across the cable strand insertion opening in the circumferential direction, the circular strand with a diameter corresponding to the inscribed circle is in electrical contact with the outer shield in any case due to the clamping mechanism.
[0032] In another advantageous embodiment of the cable retainer insert of the invention, a second groove, preferably circumferential, may be provided, which is configured to receive a radially resilient member. This second groove may be specifically located in the housing contact portion, and the radially resilient member is preferably conductive.
[0033] Furthermore, the cable contact portion and the housing contact portion are preferably integrally connected to each other. Therefore, the potential provided by the external shield and / or the shielding and / or protective grounding strands of the strands is leveled and provided at both the cable contact portion and the housing contact portion. Thus, a conductive radially elastic member can be configured to establish electrical contact between the cable retainer insert and the connector housing.
[0034] The conductive radially elastic member can be a continuous helical spring, such as a helical spring joined at its two ends by welding, or it can be a circular self-locking ring, i.e., a metal ring including an elastic contact latch (leaf spring) that can deflect in the radial direction or relative to the radial direction. A latter embodiment of the radially elastic member can be, for example, a circular V-shaped spring.
[0035] It is particularly advantageous if the first and / or second grooves are open in a radially outward direction. This has the advantage that, on the one hand, the clamping mechanism and / or radially elastic member can be used for electrical contact, and on the other hand, the clamping mechanism and / or radially elastic member can be used to hold the cable retainer plug module in a fixed position relative to each other.
[0036] Therefore, in the pre-assembled state, the strands of the multi-strand cable are housed in corresponding cable receptacles, and the outer shield is placed on the cable contact portion. A clamping mechanism can be mounted at or around the cable contact portion, and the clamping mechanism and / or radially resilient member can releasably secure the cable retainer insert module and the strands relative to each other.
[0037] The cable retainer insert of the present invention can be further improved by providing a central through-hole extending in the axial direction. The advantage of this central through-hole is that strands of multi-strand wires without shielding or requiring shielding can be easily fed through the cable retainer insert. However, strands without individual shielding may still be shielded by an external shield.
[0038] In another embodiment of the cable retainer plug of the present invention, a central plug module may be disposed in a central through-hole. The central plug module may comprise a polymer, preferably a non-conductive polymer, and more preferably an elastomer.
[0039] In embodiments including at least two cable retainer insert modules, these modules may be arranged on the outer peripheral surface of the central insert module. The central insert module may have a through-hole for receiving at least one strand of a multi-strand wire. The material of the central insert module may have a lower hardness than the material of the cable insert module. The central insert module may be vibration-damping or vibration-isolieving.
[0040] Any embodiment of the cable retainer insert can be applied to the connector of the present invention. The connector is preferably a connector back cover, more preferably a connector back cover for agricultural use.
[0041] The connector of this invention allows for the termination of multi-strand cables without compromising the shielding provided by the cables. Therefore, the connector achieves continuous 360° shielding without being interrupted by the connector itself.
[0042] With the help of modular cable retainer plugs, i.e. cable retainer plugs that include at least two cable retainer plug modules, the connectors of the present invention can be adapted to or applied to a variety of multi-strand cables, and are therefore very versatile.
[0043] If the technical features described above are introduced in singular or plural form, it does not preclude the provision of one or more of the aforementioned technical features.
[0044] In the following description, the invention will be described with reference to the accompanying drawings, which illustrate exemplary embodiments.

[0055] exist Figures 1 to 8 The image shows different views of the cable retainer plug 1 of the present invention. Figure 1 and Figure 2 The first embodiment is shown. Figures 3 to 7 A second embodiment is shown. Figure 8 A third embodiment is shown.
[0056] All embodiments of the cable retainer plug 1 include four cable retainer plug modules 3. The embodiments shown are merely exemplary embodiments; that is, different numbers of cable retainer plug modules 3 may be provided. In another embodiment of the cable retainer plug 1 of the present invention, the cable retainer plug 1 is a single piece, i.e., not modular.
[0057] In the illustrated embodiment, each cable retainer plug module 3 includes at least one cable receiving portion 5, wherein one of the cable retainer plug modules 3 includes three cable receiving portions 5. For clarity, only... Figure 1 All cable receptacles 5 are marked with reference numerals.
[0058] Each cable receiving portion 5 includes a cable strand insertion opening 7 located at its outer end 9 in the radial direction 15. For clarity, in Figure 1 The cable strand insertion opening 7 of the right cable retainer plug module 3 is shown in dashed line.
[0059] Opposite to the outer end 9, each cable receptacle 5 includes a bottom 11 at its radially inner end 13. Therefore, the cable receptacle 5 extends and opens in the radial direction 15, and further corresponds to a groove 17 in the axial direction 19, which is oriented to enter the drawing plane and is open in and relative to the axial direction 19. The cable receptacle 5 is arranged along a circumferential direction 23 perpendicular to the radial direction 15.
[0060] The four cable retainer plug-in modules 3 of the first embodiment constitute the cable contact portion 21 of the cable retainer plug-in 1. Note that the rotation direction of the circumferential direction 23 is not important, but merely a matter of definition.
[0061] In the second and third embodiments of the cable retainer plug 1 of the present invention, Figures 5 to 8 The cable contact portion 21 is best seen in the middle.
[0062] The second and third embodiments of the cable retainer plug 1 of the present invention also include a housing contact portion 25. This housing contact portion 25 is configured as a housing for an electrical contact connector (see...). Figure 13 ).
[0063] The diameter 27 of the cable contact portion 21 is smaller than the diameter 29 of the housing contact portion 25. For example... Figure 4 As shown.
[0064] from Figure 5 and Figure 6 As can be seen in the perspective view shown, both the cable contact portion 21 and the housing contact portion 25 are cylindrical, and the cable retainer plug module 3 in all the illustrated embodiments is a cylindrical segment 31 (only in...). Figure 6 The cylindrical section 31 is shown in the accompanying drawings.
[0065] from Figure 8 As can be seen most clearly, the axial length 33 of the cable contact portion 21 is greater than the axial length 35 of the housing contact portion 25.
[0066] exist Figure 2 As shown, the inscribed circle 37 (also called the inner circle 37) of the bottom 11 of the cable receiving portion 5 extends radially, i.e., in the radial direction 15, beyond the cable strand insertion opening 9. This is the case for all cable receiving portions 5, regardless of their size.
[0067] It should be noted that the bottom 11 of the cable receiver 5 shown is formed as a semicircle, and different shapes of the bottom 11 can be conceived in different embodiments. In this case (not shown), the circle 37 contacts the cable receiver 5 at at least three points. In any case, in the embodiment with the housing contact portion 25, the inscribed circle also extends in the radial direction 15 beyond the cable strand insertion opening 7, see Figure 4 .
[0068] like Figures 5 to 5 As shown, the cable contact portion 21 includes a first circumferential groove 39. In Figure 8 The first circumferential groove 39 is not present in the third embodiment shown.
[0069] also, Figures 5 to 8 The cable contact portion 21 is shown. Figure 8 A clamping mechanism 43 in the form of a band 45 is provided at the first circumferential groove 39 of the cable contact portion 21. Figures 5 to 7 ).
[0070] The clamping mechanism 43 extends across the cable harness insertion opening 7 in the circumferential direction 23.
[0071] Furthermore, a second circumferential groove 41 is provided in the housing contact portion 25. This second circumferential groove 41 is configured to receive a radial elastic member 47, which can be implemented as a continuous helical spring 49.
[0072] from Figures 5 to 8 As can be seen, both the first circumferential groove 39 and the second circumferential groove 41 extend and open in the radial direction 15.
[0073] In the following text, Figures 9 to 13 Different assembly steps of the connector 51 of the present invention are shown. The connector 51 of the present invention can be, in particular, a connector back cover 53, and is preferably an agricultural connector 55 (see...). Figure 13 and Figure 15 ).
[0074] exist Figure 9 The present invention provides a multi-strand cable 57 comprising a plurality of cable strands 59, some of which may include a shield 61 in the form of mesh 63 or braided wire 65. The multi-strand cable 57 may further include a protective grounding strand 67 and several data line strands 69. The multi-strand cable 57 may, in particular, be a round hybrid cable 57a.
[0075] In the illustrated embodiment, cable strands 59 are received in some cable receptacles 5. Due to the geometry of the cable receptacle 5 (see the description of circle 37 above), the cable strands 59, particularly the protective grounding strand 67 and the shield 61, extend radially beyond the cable strand insertion opening 7. Figures 9 to 13 The insertion opening 7 is not shown in the image, but it is referenced in the image. Figure 4 The inner circle 37 can represent three cable strands 59 having a shield 61 and a protective grounding strand 67.
[0076] Therefore, each shield 61 and protective grounding strand 69 extends in the radial direction 15 beyond the bottom 11 of the first circumferential groove 39.
[0077] exist Figure 10 In the middle, the radial elastic member 47 is disposed in the second circumferential groove 41 of the housing contact portion 25, thereby fixing the position of the four cable retainer plug modules 3.
[0078] exist Figure 11 The diagram shows that the multi-strand cable 57 also includes an outer shielding layer 71, which, for clarity, is shown in... Figure 9 and Figure 10 Not shown in the diagram. The cable contact portion 21 is inserted into the external shield 71.
[0079] exist Figure 12In the middle, the clamping mechanism 43 of the form 45 is inserted into the first circumferential groove 39. Thus, the outer shield 71 is pressed against the bottom 11 of the first circumferential groove 39 and against the shield 61 and the protective grounding strand 67 (e.g., in...). Figure 14 (See image). Since the cable retainer plug 1 is conductive, it is electrically contacted by the shield 61 of the cable strands 59 and the outer shield 71. In this pre-assembled state 73, the outer shield 71 is arranged between the cable strand insertion opening 7 (covered by the outer shield 71 and the band 45) and the clamping mechanism 43.
[0080] Finally, as Figure 13 and Figure 15 As shown, the cable retainer plug 1 is housed in the connector housing 75, thereby forming the connector 51 in an assembled state 77.
[0081] exist Figure 13 As can be seen, the outer shield 71, the (invisible) protective grounding strand 69, and other shields 61 are connected to the metal housing portion 79 of the housing 75 via the housing contact portion 25 and the radial elastic member 47. The rear portion 79a of the metal housing portion 79 overlaps with the outer shield 71, thereby providing uninterrupted shielding for all strands 59 of the multi-strand cable 57.
[0082] The metal housing portion 79 also includes a front portion 79b that further provides shielding in the axial direction 19.
[0083] Figure 15 The entire connector 51 is shown, which also includes a front cover member 81, which is attached to the metal housing portion 79 by a retaining mechanism 83.
[0084] exist Figure 14 The image shows another embodiment of the cable retainer plug 1 of the present invention. This embodiment provides a central plug module 85 located in a central through-hole 87. The central through-hole extends in the axial direction 19. The central plug module 85 may include a polymer 89 and may preferably be non-conductive or elastic to reduce vibration of the data strands 59 received in the through-hole 85a of the central plug module 85. The central plug module 85 may also include an elastomer.
[0085] Figures 15 to 19 Another embodiment of the cable retainer plug 1 of the present invention is shown, which differs from the previously shown embodiment of the cable retainer plug 1 in that only one cable retainer plug module 3 is provided. Therefore, this cable retainer plug 1 is not modular.
[0086] Figures 16 to 20This embodiment of the cable retainer plug 1 of the present invention further includes another embodiment of a radial elastic member 47, which is a circular leaf spring member 91 that includes a circumferential base spring 93 (see...). Figure 17 and 20 ) and multiple leaf springs 95. The circular leaf spring component 91 can also be represented as a circular self-locking ring. In Figure 17 and 18 In the figure, only some of the leaf springs 95 arranged circumferentially are marked with reference numerals. Such circular leaf spring members 91 provide electrical and mechanical connection between the cable retainer insert 1 and the metal housing portion 79 of the connector 51 (see figure). Figure 20 ).
[0087] Figures 16 to 20 The cable strand 59 shown is provided with a collar 97, which is electrically connected to the shield 61 of the corresponding cable strand 59 via electromagnetic pulse technology.
[0088] Figures 16 to 20 The embodiment of the cable retainer plug 1 of the present invention shown also includes cable receiving portions 5 of different shapes, in Figure 18 The most clearly visible feature is the retaining housing 99, which has a minimum insertion diameter 101 smaller than the ferrule insertion diameter 103. It should be noted that the ferrule 97 may include a guide collar 105 for positioning the ferrule 97 relative to the cable retainer insert 1 by interacting with the guide collar 105 having a stop shoulder 107. The ferrule 97 also includes a sheet sleeve 109, which provides a plurality of individually deflectable sheets (not specified in the figures) to provide electrical contact between the ferrule 97 and the cable retainer insert 1. Figure 19 The image shows the contact between the thin-film sleeve 109 and the cable retainer insert 1 in a cross-sectional view. Furthermore, Figure 20 This indicates the transfer of potential in the shield 61 via the transfer path 111 indicated by the arrow. Path 111 extends from the shield 61 through the ferrule 97 to the cable retainer insert 1, and then from the circular leaf spring member 91 to the metal housing portion 79 of the connector 51. It should be noted that in... Figure 20 In the middle, the circular leaf spring member 91 is compressed when it comes into contact with the metal housing part 79.
