Description

Technical Field

[0001] The present invention relates to a stranded wire protection plate for clamping the stranded wires of a cable in a stranded wire clamping body by a clamping screw acting on the stranded wire protection plate and screwed into the stranded wire clamping body, wherein the stranded wire protection plate has a stranded wire clamping tongue for pressing against the stranded wire, a bending area, and a contact area for pressing against the stranded wire clamping body, wherein the stranded wire clamping tongue is connected to the contact area through the bending area and a through opening is provided in the contact area for guiding the clamping screw through. Background Technology

[0002] This type of stranded wire protection plate is known in the prior art. They are used to ensure that the strands of a cable are securely clamped by clamping screws when fastened in the stranded wire clamping body, and are not excessively damaged. For this purpose, it is specified that when the respective strands are clamped in the stranded wire clamping body, the clamping screws do not act directly on the strands, but rather utilize the stranded wire clamping tongues acting between them.

[0003] This type of stranded wire protection plate is used in a wide variety of electrical plugs. When these connectors are delivered, the clamping screws are typically loosely screwed into the stranded wire clamping body. The stranded wire is then usually clamped into the stranded wire clamping body only later by the clamping screws and the stranded wire protection plate.

[0004] When electrical plugs are delivered and transported, the stranded wires of the cable are usually not yet attached to the stranded wire clamps. Therefore, vibration may cause the clamping screws to loosen from the stranded wire clamps and be lost during transportation, or the clamping screws may have to be screwed back into the corresponding stranded wire clamps at a considerable cost.

[0005] To prevent this from happening, it is known in the prior art to secure the clamping screws in the stranded wire clamping body for transport by using adhesives or thread deformation. However, this is time-consuming because the application of adhesives or thread deformation represents an additional working step in the manufacture of electrical plugs. Summary of the Invention

[0006] The purpose of this invention is to provide a different solution to this problem, which prevents the clamping screws on the electrical plug from accidentally detaching from the stranded wire clamping body during transportation due to vibration or other reasons.

[0007] To address this problem, the present invention proposes a stranded wire protection plate for clamping the stranded wires of a cable within a stranded wire clamping body using clamping screws. The clamping screws act on the stranded wire protection plate and are screwed into the stranded wire clamping body. The stranded wire protection plate has a stranded wire clamping tongue for pressing against the stranded wires, a bending region, and a contact region for pressing against the stranded wire clamping body. The stranded wire clamping tongue is connected to the contact region via the bending region, and a through opening is provided in the contact region for guiding the clamping screw through. At least one clamping claw is formed adjacent to the through opening in the contact region for securely clamping the clamping screw guided through the through opening.

[0008] Therefore, according to the present invention, at least one clamping claw is formed on the contact area adjacent to the conductive opening for fixing the clamping screw guided through the conductive opening.

[0009] Therefore, in this invention, the stranded wire protection plate has at least one clamping claw, which holds the clamping screw screwed into the stranded wire clamping body in a fixed clamping manner, so that the clamping screw will not be accidentally loosened and fall out of the stranded wire clamping body during transportation.

[0010] Although it is explicitly stated here that the stranded wire protection plate is suitable for clamping stranded wires (i.e., several wires twisted together), it should be noted that, of course, individual wires can also be clamped in the stranded wire clamping body using the stranded wire protection plate according to the invention.

[0011] Particularly preferably, clamping claws are formed on opposite sides of the conductive opening and adjacent to the conductive opening in the contact area, for fixing the clamping screw guided through the conductive opening between the clamping claws.

[0012] Regardless of whether the stranded wire protection plate has one, two, or more clamping claws, the clamping claws preferably have a resilient design. They may also be referred to as resilient lugs. The stranded wire protection plate is preferably made of a conductive material, particularly preferably of metal. A preferred variation specifies that the entire stranded wire protection plate is integrally formed. Particularly preferably, the stranded wire protection plate is a stamped and bent part. Stamped and bent parts are components produced from sheet metal through stamping and bending operations.

[0013] Therefore, this invention eliminates the need for the previously required adhesive or thread deformation. The stranded wire protection plate itself ensures that the clamping screws will no longer accidentally come loose from the stranded wire clamping body due to vibration.

[0014] Therefore, it is specified that one or more clamping jaws press against the clamping screw guided through the through opening, such that they hold the clamping screw in a clamping manner. A particularly preferred variation specifies that the clamping jaws, preferably each clamping jaw, have a free-protruding end edge for engaging in the threads of the clamping screw.

[0015] Particularly preferably, the end edge of one of the clamping claws extends further in the direction of the stranded wire clamping tongue than the end edge of the clamping claw on the opposite side of the conduction opening. In this case, the positions of the end edges can be adapted to the pitch of the thread of the clamping screw to be used. Then, particularly preferably, one of the end edges extends further in the direction of the stranded wire clamping tongue than the end edge of the clamping claw on the opposite side of the conduction opening by half the pitch of the clamping screw. This also prevents unintentional misalignment of the clamping screw as it passes between the clamping claws and their end edges.

[0016] With the two clamping jaws facing each other relative to the conductive opening, the distance between the end edges of the two clamping jaws is advantageously slightly smaller than the outer diameter of the clamping screw before the clamping screw is screwed in. This results in particularly good clamping of the clamping screw between the clamping jaws. Therefore, when the clamping screw is screwed into the stranded wire clamping body, one or more clamping jaws elastically deflect, meaning they then press against the clamping screw with a certain preload, thereby firmly clamping the clamping screw in the proper position.

[0017] To make the insertion of the clamping screw slightly easier, it can be specified that the clamping claw, preferably each clamping claw, has an insertion bevel for clamping the screw at its end opposite to the edge of the free-protruding end.

[0018] Particularly preferably, the clamping claws located on opposite sides of the conduction opening and adjacent to the conduction opening are configured to be inclined apart relative to each other, starting from their respective end edges. Alternatively, the clamping claws are preferably configured to taper towards each other towards their end edges. On the one hand, this simplifies the insertion of the clamping screw between the two clamping claws. On the other hand, this also improves the clamping retention force of the clamping screw located between the clamping claws. Particularly preferably, the angle formed by the clamping claws relative to each other is in the range of 10° to 60°, preferably in the range of 10° to 30°, and in a particularly preferred variant, 24°.

[0019] In any case, it is preferably specified that one or more clamping jaws, preferably each clamping jaw being at least substantially located on the side of the contact area opposite to the stranded wire clamping tongue.

[0020] The strand clamping tongue (i.e., the area of ​​the stranded wire protection plate that directly abuts against the stranded wire) can be bent to form a recess surrounding the stranded wire in certain areas. As seen in the side view, in the unassembled state, the strand clamping tongue and the contact area can be arranged parallel to each other. However, it is preferably specified that, as seen in the side view, the strand clamping tongue and the contact area are separated at an angle away from the opening of the bending area. This angle is advantageously in the range of 4° to 10°, and particularly preferably between 5° and 7°. In the unloaded state of the stranded wire protection plate, this slight angular position between the strand clamping tongue and the contact area simplifies the insertion of the strand clamping tongue into the strand receiving space of the strand clamping body.

[0021] To facilitate easy attachment of the stranded wire protection plate and the stranded wire clamping body to the plug housing of the electrical plug, a preferred embodiment of the invention provides a fixing lug angled relative to the contact area on the contact region of the stranded wire protection plate on the side opposite to the bending area. This fixing lug presses against the plug housing, allowing the stranded wire clamping body and the stranded wire protection plate to be easily and securely attached to the plug housing in the appropriate position.

[0022] In addition to the stranded wire protection plate itself, the present invention also relates to an electrical plug contact having a contact pin, a stranded wire clamping body, a clamping screw screwed into the stranded wire clamping body, and a stranded wire protection plate according to the invention. In the case of such an electrical plug contact, according to the invention, the clamping screw passes through a conductive opening in the contact area of ​​the stranded wire protection plate and is screwed into the stranded wire clamping body and clamped by at least one clamping claw. The stranded wire clamping body and the contact pin can, for example, be designed as an integral part. In this case, for example, it may be a machined part. However, the contact pin and the stranded wire clamping body can initially be designed as two separate parts. The contact pin can then be clamped together with the stranded wire in the stranded wire clamping body. In particular, in this case, the contact pin can be a stamped and bent part. In the electrical plug, both of the above-described variations or only one of the above-described variations can be implemented. If the contact pin and the stranded wire clamping body are integral parts, they can be arranged in a particularly space-saving manner within the insertion space of the electrical plug into which the electrical contacts of the adapter connector are inserted. If the contact pin is a stamped and bent part, it is preferably disposed on the outer periphery of the insertion space of the electrical plug. It should be understood that the two variations of the contact pin mentioned may also be used in different ways and / or in different locations.

[0023] In addition to the stranded wire protection plate and electrical plug contacts, the present invention also relates to an electrical plug for transmitting power and / or electrical signals, wherein the plug includes a plug housing and at least one electrical plug contact according to the invention. Such an electrical plug according to the invention can be used as a purely electrical plug, i.e., for transmitting only electrical signals or power. However, such an electrical plug according to the invention can also be a hybrid connector designed to transmit both power or electrical signals and optical signals. Attached Figure Description

[0024] In the following, preferred details and features of the stranded wire protection plate, electrical plug contacts, and electrical plug according to the present invention are explained by way of exemplary embodiments, wherein:

[0025] Figures 1 to 21 A schematic diagram of a first exemplary embodiment of an electrical plug with a corresponding stranded wire protection plate according to the present invention is shown. Figures 22 to 26 The variant modified as described is shown. Detailed Implementation

[0026] Figure 1 and Figure 2 A first electrical plug 17 according to the present invention is shown. The electrical plug 17 can be used to transmit power and / or electrical signals. In the exemplary embodiment shown herein, the electrical plug 17 is a purely electrical plug. However, as described above, the electrical plug 17 according to the present invention can also be designed as a hybrid plug and may have optical contacts for transmitting optical signals in addition to the electrical plug contacts 15 for transmitting power and / or electrical signals. Figure 1 and Figure 2 Only a portion of the housing 18 of the electrical plug is shown. For example, it may also have housing elements, etc., which are not shown here and are not relevant to the present invention.

[0027] Figure 1 A view is shown in which the twisted wire insertion opening 19 of the plug housing 18 can be seen, the twisted wire 2 is inserted into the twisted wire insertion opening 19, and then clamped in the corresponding twisted wire clamping body 4 by means of the twisted wire protection plate 1 and the clamping screw 5. Figure 2 This shows the view from the opposite direction. Figure 1 This is a view of the electrical plug 17, thus revealing the insertion space 21 of the plug housing 18. The pins 16 of the electrical plug contacts 15 are located within this insertion space 21. Corresponding adapter contacts of corresponding adapter plugs (not shown here) are inserted into the insertion space 21. Figure 2 The presence of a contact pin 16 located at the center of the insertion space 21 and at the outer edge of the plug housing 18 is also clearly shown.

[0028] Indicator lugs 20 are provided on the outer side of the plug housing 18. This is well known. They are used to prevent the plug 18 from mating with the corresponding adapter plug that is in the wrong position.

[0029] Figure 3 A front view of the plug housing 18 and the stranded wire insertion opening 19 disposed therein is shown. The stranded wire clamping tongue 6 of the corresponding stranded wire protection plate 1 can be seen here. The clamping screws 5 disposed at the edge are also visible. Figure 3 In the diagram, section line AA is drawn. Figure 4 A longitudinal section is shown along section line AA passing through electrical plug 17. According to... Figure 4 In the longitudinal section, it can be seen how the two electrical plug contacts 15 are arranged inside the housing 18. Their contact pins 16 are located at the center of the insertion space 21 of the plug housing 18. The contact pins 16 of these electrical plug contacts 15 are integrally formed with the corresponding stranded wire clamping body 4. In each case, a clamping screw 5 is screwed into the stranded wire clamping body 4. According to the invention, each electrical plug contact 15 includes a stranded wire protection plate 1 according to the invention. Figures 16 to 19 The stranded wire protection plate 1 according to the invention, used in the exemplary embodiment shown herein, is shown separately and is also described separately there. However, from Figure 4 As can be clearly seen, the stranded wire protection plate 1 has a stranded wire clamping tongue 6, which is configured to contact the stranded wire 2 when the stranded wire 2 (not shown) is securely clamped in the stranded wire receiving space 22 by the clamping screw 5 and the stranded wire clamping tongue 6 is inserted. Figure 8 As shown herein, and will be further explained below, the stranded wire protection plate 1, in addition to the stranded wire clamping tongue 6, also has a contact area 8 and a bending area 7 for pressing against the stranded wire clamping body 4. The stranded wire clamping tongue 6 is connected to the contact area 8 via the bending area 7. The contact area 8 includes a through opening 9 through which the clamping screw 5 passes. In the preferred embodiment shown here, a fixing lug 14 is provided at the end of the contact area 8 of the stranded wire protection plate 1 opposite to the bending area 7. Figure 4 As can be seen, the fixing lug is inclined toward the contact area 8 and is used to fix the electrical plug contact 15 in the housing 18.

[0030] Not in Figure 4 The stranded wire 2 shown can be inserted into the corresponding stranded wire receiving space 22 of the corresponding stranded wire clamping body 4 through the stranded wire insertion opening 19 in the plug housing 18, so that it can be clamped there by the clamping screw 5 when the stranded wire clamping tongue 6 is inserted.

[0031] Figure 5 and Figure 6 This shows the part removed from the plug housing 18 again. Figure 4 Electrical plug contact 15. Figure 5 It is an external 3D view. Figure 6 It's a longitudinal section. Figure 5 and Figure 6 As can be clearly seen here, in the electrical plug contact 15, the corresponding contact pin 16 is integrally connected to the stranded wire clamping body 4. Preferably, this integral part is a machined part. Figure 6 In the diagram, it can also be clearly seen how the stranded wire protection plate 1 abuts against the stranded wire clamping body 4 through its contact area 8 and extends into the stranded wire receiving space 22 of the stranded wire clamping body 4 through its stranded wire clamping tongue 6.

[0032] Figure 7 Now shown is the crossing according to Figures 4 to 6 A diagram of a longitudinal section of the electrical plug contact 15, wherein... Figure 7 In the middle, the stranded wire 2 of the cable 3 is now inserted into the stranded wire receiving space 22 of the stranded wire clamping body 4. Figure 7 This shows the state before the stranded wire 2 is clamped in the stranded wire clamping body 4. On the other hand, in Figure 8 The image shows the fixed clamping state. It can be clearly seen there how the clamping screw 5, screwed into the stranded wire clamping body 4 to a correspondingly large extent, acts on the stranded wire 2 via the stranded wire protection plate 1, or particularly its stranded wire clamping tongue 6, to securely clamp it within the stranded wire clamping body 4. Specifically, the clamping screw 5 presses the stranded wire clamping tongue 6 against the stranded wire 2, such that the latter is clamped between the stranded wire clamping tongue 6 and the opposing wall of the stranded wire clamping body 4 that defines the stranded wire receiving space 2.

[0033] Figure 9 The electrical plug 17 of the first exemplary embodiment is shown in relation to... Figure 3 Same view. However, here, section line BB is drawn. Figure 10 A corresponding longitudinal section is shown through the plug housing 18 and the electrical plug contact 15 disposed therein, with the contact pin 16 of the electrical plug contact 15 located in the outer region of the insertion space 21. As shown here by way of example, the electrical plug contact 15 does not necessarily have to be an integral design. Here, the contact pin 16 is a separate component clamped together with the stranded wire 2 in the stranded wire clamping body 4. This allows the contact pin 16 to be designed as a stamped and bent part that can be manufactured relatively inexpensively, as also achieved here. The stranded wire protection plate 1 used here is used in conjunction with the... Figures 4 to 8 The same applies to the electrical plug contacts 15. This also applies to the clamping screws 5 that pass through the conductive opening 9 of the stranded wire protection plate 1 and are screwed into the stranded wire clamping body 4.

[0034] Figure 11 This type of electrical plug contact 15 is shown removed from the plug housing 18. Figure 12 The stylus 16, which is separate from all other components, is shown here as a stamped and bent part. Figure 13 A longitudinal section passing through the contact 15 of this type of electrical plug is shown again. Specifically, from... Figure 10 As can be seen from this, the fixed lug 14 has the same characteristics as the one based on Figures 4 to 8 The variant shown has the same function. Figure 10 and Figure 13 In the diagram, it can be clearly seen how the corresponding end of the contact pin 16 and the stranded wire clamping tongue 6 of the stranded wire protection plate 1 are positioned in the stranded wire receiving space 22 of the stranded wire clamping body 4 so that the stranded wire 2 can be inserted between them. Figure 14 This can be seen from the text. Figure 15 The diagram again shows the state in which the stranded wire clamping tongue 6 is pressed onto the stranded wire 2 by the clamping screw 5, so that the stranded wire 2 and the contact pin 16 are clamped in the stranded wire receiving space 22 of the stranded wire clamping body 4.

[0035] For the sake of completeness, it should be noted that, as implemented in this exemplary embodiment, the plug housing 18 is advantageously designed such that even if the contact pin 16 has not yet been clamped by the stranded wire 2, the stranded wire protection plate 4, and the clamping screw 5, it will... Figures 10 to 15 The corresponding stylus 16 shown is held in the proper position.

[0036] Figure 16 and Figure 17 Now shown is a stranded wire protection plate 1, designed according to the invention and separate from all other components of the electrical plug contact 15 or electrical plug 17, used in the exemplary embodiment shown herein. First, the contact area 8 and the stranded wire clamping tongue 6 are clearly shown connected to each other via the bending area 7. The contact area 8 also includes a conductive opening 9, not in… Figure 16 and Figure 17 The clamping screw 5 shown can pass through the conductive opening. In the variation shown here, clamping claws 10 are formed on opposite sides of the conductive opening 9 and adjacent to the conductive opening 9 on the contact area 8, for clamping and holding the clamping screw 5 guided through the conductive opening 9 between the clamping claws 10. However, as explained at the beginning, even one clamping claw 10 provided adjacent to the conductive opening 9 is sufficient to securely clamp the clamping screw 5 guided through the conductive opening 9. Figure 16 and Figure 17 It can also be seen that each clamping claw 10 has a freely protruding end edge 11, as shown in the reference. Figure 20 and Figure 21 As shown, the corresponding clamping claw 10 can be engaged in the thread 12 of the clamping screw through the end edge.

[0037] exist Figure 16 and Figure 17 It can also be seen that the strand clamping tongue 6 is preferably curved so as to surround the strand 2 in at least some areas during clamping.

[0038] As seen in the side view, the stranded wire clamping tongue 6 and the contact area 8 can be arranged parallel to each other in the unloaded state. However, in order to simplify the assembly of the stranded wire protection plate 1 on the stranded wire clamping body 4, a preferred variation is specified, for example, as... Figure 17 As shown, in the unloaded state, as seen in the side view, the stranded wire clamping tongue 6 and the contact area 8 are separated at an angle 23 that opens away from the bending area 7. As explained at the beginning, this angle 23 is advantageously located between 4° and 10°, and particularly preferably between 5° and 7°. In the unloaded state of the stranded wire protection plate 1, this small angular position between the stranded wire clamping tongue 6 and the contact area 8 simplifies the insertion of the stranded wire clamping tongue 6 into the stranded wire receiving space 22 of the stranded wire clamping body 4.

[0039] Figure 18 It shows along Figure 17 The section line CC passes through the section of the stranded wire protection plate 1. Figure 18 As can be clearly seen in the preferred exemplary embodiment, the end edge 11 of one of the clamping claws 10 extends further in the direction toward the stranded wire clamping tongue 6 than the end edge 11 of the clamping claw 10 located on the side opposite to that clamping claw in the conduction opening 9. The function of this different length design of the clamping claws 10 will be referred to below. Figure 21 Further explanation.

[0040] Figure 18 It is also clearly shown that the clamping claws 10, located on opposite sides of and adjacent to the conduction opening 9, are preferably arranged to be obliquely separated from each other, starting from their respective end edges 11. Particularly preferably, the angle 24 formed by the clamping claws 10 relative to each other in the unloaded state is in the range of 10° to 60°, preferably in the range of 10° to 30°. In the exemplary embodiment shown here, the angle is 24°.

[0041] Figure 19 Enlarged display Figure 18 Region D is shown in the image. Here, the end edge 11 and the insertion bevel 13 at the end of the clamping claw 10 opposite to the free-protruding end edge 11 are clearly visible. The insertion bevel 13 facilitates the insertion or screwing of the clamping screw 5 between the clamping claws 10.

[0042] Figure 20 A perspective view illustrates how the clamping screw 5 is clamped between the clamping jaws 10. As per... Figure 21As shown in the cross-section, it is preferably specified that the end edge 11 engages in the thread 12 of the clamping screw 5.

[0043] like Figure 21 As shown, different arrangements of the end edges 11 in the direction of the wire clamping tongue 6 can be used to adapt the position of the end edges 11 to the pitch of the thread 12 of the clamping screw 5 to be used. Particularly preferably, as also... Figure 21 As shown, it is then specified that one of the end edges 11 extends further in the direction of the stranded clamping tongue 6 by half the amount of the pitch of the clamping screw 5 than the end edge 11 of the clamping claw 10 located on the opposite side of the conduction opening 9. In this way, as explained at the beginning, accidental deflection of the clamping screw 5 can also be prevented when the clamping screw 5 passes between the clamping claw 10 and their end edges 11.

[0044] According to Figure 21 The illustration shows one thread crest of the thread 12 located within the corresponding clamping jaw 10. This is purely a matter of drawing. In reality, the thread 12 may cut into the clamping jaw 10, or the clamping jaw 10 may be pushed slightly further away by the thread 12. This does not change the function shown.

[0045] at last, Figures 22 to 26 Other variations of the electrical plug 17 that can be equipped with the stranded wire protection plate 1 according to the invention are shown, as well as various variations of the electrical plug contacts 15 that have already been explained with reference to the first exemplary embodiment. Therefore, further explanation is unnecessary. Figures 22 to 26 The description will only discuss and be based on Figures 1 to 21 The difference from the first implementation method.

[0046] exist Figure 22 and Figure 23 In this design, the electrical plug 17 and its plug housing 18 contain only two electrical plug contacts 15. This can be easily seen from the fact that the plug housing 18 also contains only two twisted wire insertion openings 19. Figure 23 As can be seen from the insertion space 21, the contact pin 16 of one of the two electrical plug contacts 15 is again positioned at the center of the insertion space 21. The electrical plug contact 15 with this contact pin 16 can be positioned as follows: Figures 5 to 8 Design as shown. According to... Figure 22 and Figure 23 Another contact pin 16 in the insertion space 21 of the electrical plug 17 is located at the edge of the insertion space 21, which can be Figures 11 to 15 The electrical plug contact 15 is shown.

[0047] Figures 24 to 26A variation of the electrical plug 17 is now shown, which has three stranded wire insertion openings 19 in its plug housing 18 and correspondingly three electrical plug contacts 15. Figure 24 and Figure 25 The first exemplary embodiment is shown in two opposite views. The two electrical plug contacts 15 of this exemplary embodiment are as follows: Figures 10 to 15 It is formed as shown and disposed edge-to-edge in the plug housing 18. Furthermore, one of the electrical plug contacts 15 is as shown... Figures 4 to 8 It is formed as shown and is positioned at the center of the insertion space 21.

[0048] Figure 26 It shows the relationship with Figure 24 and Figure 25 The plugs are essentially the same, the only difference being the arrangement of the indicator lugs 20 on the plug housing 18. This is to illustrate that the indicator lugs 20 can be designed and arranged differently to ensure that the corresponding electrical plug 17 can only mate with the correct adapter plug used for it. In this way, as is known per se, it is possible to prevent the plug and adapter plug from being incorrectly inserted together or incorrect plug and adapter plug from being inserted together.
