Description

Technical area

The invention relates to a short-circuit pin, a plug connection with such a short-circuit pin and a method for producing such a short-circuit pin.

State of the art

Due to the ever increasing number of electrical devices, the desire to connect different electronic devices to one another is also increasing. This is done by making a corresponding plug connection using two plugs. Such a plug connection can be faulty, which then leads to the failure of a communication connection between the two electrical devices. On the one hand, a faulty plug connection can only arise over time if, for example, forces act on the plug connection. On the other hand, a plug connection cannot be established correctly from the start because the two plugs cannot be plugged into one another with the necessary force. The later effort for rectifying the faulty plug connection can sometimes be very high. It is therefore important to recognize a faulty plug connection.

From the DE 20 2019 104 312 U1 a test plug is known in order to be able to short-circuit a coaxial plug. This test plug is inserted into a coaxial plug. If a plug connection to another coaxial connector is established via this coaxial connector, then its inner conductor is short-circuited with its outer conductor. This can be recognized at an early stage via a corresponding control device and the plug connection, which has further connections, can be repaired accordingly. The test plug comprises a contact spring which contacts an inner conductor and an outer conductor at the same time and thus short-circuits them. The contact spring is held by a housing. The housing includes a receptacle for the inner conductor to be short-circuited. at When the inner conductor is inserted into the receptacle, contact with the contact spring takes place. Another part of the contact spring is used to contact the outer conductor and protrudes from the housing. The contact spring is pushed into the housing in the same direction as the inner conductor later. The contact spring increases in width from the contacting end and includes slotted locking wings. The test plug shown can only be manufactured with great difficulty or at all in an automated manner. This is all the more true, the smaller the coaxial connector. In the case of inner conductors with a diameter of less than 1 mm, the contact spring is inherently very unstable. In the case of micro-coaxial lines, the inner conductors of the coaxial cable to be picked up can have a diameter of approximately 0.4 mm. The dimensions that a necessary test plug must have are correspondingly small. The assembly of the test plug from the prior art is therefore extremely problematic for such dimensions and cannot be achieved in an automated manner.

Description of the invention

It is therefore the object of the present invention to create a short-circuit pin for short-circuiting an inner conductor with an outer conductor in a multiple coaxial connector of a plug connection, which comprises an improved structure and is suitable for accommodating even the smallest inner conductor diameter, with the production of this short-circuit pin being possible in an automated manner should be.

The object according to the invention is achieved by a short-circuit pin, a plug connection with a short-circuit pin and a method for producing such a short-circuit pin with the features of the independent claims. Further advantageous embodiments of the invention can be found in the subclaims, the description and the drawings.

The short-circuit pin according to the invention comprises a contact spring which consists of an electrically conductive material or comprises such a material. The inner conductor is electrically connected to the outer conductor via a low-resistance connection (galvanically) via the contact spring and thus short-circuited. In contrast to the prior art, the contact spring also includes a holding and stabilizing section in addition to a contacting section. Both sections extend along a longitudinal axis of the contact spring. The contacting section is bent and comprises an inner conductor contact section and an outer conductor contact section, which are spaced apart from one another perpendicularly or transversely to the longitudinal axis of the contact spring. The contacting section is preferably resilient with respect to the holding and Stabilization section formed. In addition, the inner conductor contact section can also be designed to be resilient with respect to the outer conductor contact section. A housing delimits a receiving space which extends along, in particular the entire length, the longitudinal direction of the housing.

On its first end face, the housing comprises an inner conductor insertion opening, via which the inner conductor to be short-circuited can be inserted into the receiving space over at least part of its length. In the inner conductor insertion opening, the inner conductor to be short-circuited can be brought into electrically conductive contact with the inner conductor contact section. The housing also has a lateral outer conductor contact opening, which is preferably arranged offset by 90 ° to the inner conductor insertion opening. The outer conductor contact section protrudes through the outer conductor contact opening and can thereby be brought into electrically conductive contact with the outer conductor to be received. It is also particularly advantageous that the contact spring is arranged within the receiving space of the housing and extends over the major part of the length of the housing.

Since the contact spring extends over the major part of the length of the housing, the dimensioning of the contact spring can be selected, even with only a very small contacting section, in such a way that a comparatively simple, preferably automated, handling is possible. In this way, the invention can also be used with very small plug connectors which, for example, have an outer conductor diameter of 2 to 3 mm.

In order to further increase the stability, a further development provides that the inner conductor insertion opening and the outer conductor contacting opening are two separate openings which are separated from one another on the outside by a part of the housing. This increases the stability of the housing, especially in the area of the first end face. In this case, the contact spring is preferably free of branches. The inner conductor contact section and the outer conductor contact section are arranged one after the other.

In order to further increase the stability, the inner conductor contact section is bent back with respect to the outer conductor contact section, in particular by 180 °, and thus forms a first end of the contact spring. In principle, the outer conductor contact section can also be bent back with respect to the inner conductor contact section. The contacting section can have a hook-shaped shape. It is particularly advantageous here that the predominant part of the contact spring is arranged within the housing and only that which is bent back Part of the outer conductor contact section emerges from the corresponding outer conductor contact opening. In the prior art, the majority of the contact spring is accessible from outside the housing, which brings stability problems with it and means that the contact spring can be damaged more easily.

The housing can have a separate contact spring insertion opening, via which the contact spring can be inserted into the receiving space. The contact spring insertion opening is arranged in particular in the area of a second end face of the housing. The inner conductor insertion opening and the contact spring insertion opening are therefore preferably formed at two opposite ends of the housing. The contact spring is inserted into the contact spring opening with its contacting section first and is advanced in the direction of the inner conductor insertion opening. In the prior art, this is done exactly the other way around. Here the widened section is introduced first and the filigree contacting section at the end. The problem from the prior art of how the contact spring is ultimately to be held during insertion does not arise in the present invention because the contact spring is easily held at the free end of the holding and stabilizing section and inserted into the contact spring insertion opening with the contacting section first can.

The holding and stabilizing section of the contact spring has a curved cross-sectional geometry. It is also possible to speak of a curvature of the holding and stabilizing section transversely to the longitudinal axis. As a result, not only can the receiving space be enlarged, the contact spring still being arranged without play in the receiving space, which simplifies the manufacture of the housing. At the same time, the arched shape also increases the stability of the entire contact spring. As a result, a greater length of the contact spring can also be realized, so that it extends in particular over the major part of the length of the housing. The at least one holding and stabilizing section can have a height of preferably less than 0.8 mm, more preferably less than 0.5 mm, most preferably less than 0.4 mm.

The connector according to the invention comprises a first and a second multiple coaxial connector, in particular in the form of a micro multiple coaxial connector, the second multiple coaxial connector being the mating connector of the first multiple coaxial connector. The first multiple coaxial connector comprises at least two connections. It could also include three, four, five, six, seven, eight, or more than eight ports. The same applies to the second multiple coaxial connector. In a first connection of the The short-circuit pin is arranged in the first multiple coaxial connector. An inner conductor and an outer conductor of a coaxial cable connected to the respective connection are arranged in the at least one second connection. The first and second multiple coaxial plugs are plugged into one another, so that an inner conductor in the first connection of the second multiple coaxial plug dips into the inner conductor insertion opening of the short-circuit pin and thereby contacts the inner conductor contact section of the contact spring. An outer conductor in the first connection of the second multiple coaxial connector makes contact with the outer conductor contact section of the contact spring when it is plugged together. As a result, the inner conductor and the outer conductor are connected in an electrically conductive manner via the contact spring and short-circuited.

The inner and outer conductors in the second connection of the second multiple coaxial connector make contact with the respective inner and outer conductors in the corresponding connection in the first multiple coaxial connector via conventional measures. The inner conductors in the connections of the second multiple coaxial connector can in turn be electrically conductively connected to an inner conductor of a connected coaxial cable. They can also be connected with a plug contact. This also includes a one-piece construction, according to which the plug contact in the first connection of the second multiple coaxial connector represents the inner conductor which is inserted into the inner conductor insertion opening. The plug contact can be soldered to a circuit board. Such a plug contact can emerge from the second multiple coaxial plug preferably at an angle of 90 °. The same applies to the outer conductors of the second multiple coaxial connector.

By connecting the second multiple coaxial plug to a control device, at least that connection on which the short-circuit pin according to the invention is mounted can be queried for a short circuit. If a short circuit is detected, this is a sign that the plug connection has been established correctly and that corresponding signals can also be transmitted via the other connections.

The method according to the invention for producing the short-circuit pin comprises several method steps. These process steps are aimed in particular at automated production of the short-circuit pin. In a first process step, a contact spring belt is produced. This contact spring belt comprises a large number of contact springs which are later inserted into corresponding housings. This first process step comprises several sub-process steps. In a first sub-process step, a metal sheet is punched out and / or lasered. the end Contact springs are punched out or lasered on this sheet metal. These are separated from one another, each contact spring comprising a holding and stabilizing section, a contacting section and a connecting section. The contact springs are held together via a common upper connecting strip and a common lower connecting strip. The connecting section of each contact spring is connected to the upper connecting strip and the holding and stabilizing section of each contact spring is connected to the lower connecting strip in the region of a respective end. The contact springs are therefore separated from one another and individually suspended from the upper and lower connecting strips. Subsequently, in a further sub-process step, the contacting section is bent over, in particular towards a hook-shaped shape.

In the next method step, the connecting section is severed from the upper connecting strip. Subsequently, in a further method step, the contact spring is introduced into a receiving space of a housing via a corresponding contact spring insertion opening. The contact spring is inserted into the contact spring insertion opening with its contacting section first. After the contacting section, the connecting section, which no longer hangs on the upper connecting strip, is introduced. The holding and stabilizing section is then inserted. The contact spring itself can be moved towards the housing. However, the housing is preferably moved in the direction of the contact spring. A joint movement of the contact spring and the housing would also be possible. Finally, the holding and stabilizing section is separated from the lower connecting strip.

The use of the contact spring belt is particularly advantageous because the respective contact springs are optimally aligned in this contact spring belt and can be introduced into the respective housing accordingly. Such a contact spring belt, which can be rolled up, can comprise a multiplicity of contact springs and can be fed to a corresponding automatic placement machine. This enables the short-circuit pin according to the invention to be produced automatically.

Some particularly advantageous configurations of the short-circuit pin are highlighted again below.

The short-circuit pin 1 according to the invention is described below. This comprises a contact spring 2 and a housing. the Figures 1A and 1B show different views of a first embodiment of this contact spring 2. The contact spring 2 comprises a holding and stabilizing section 3 and a contacting section 4. Between the two sections 3, 4 there is a connecting section 5. The contacting section 4 is bent over by 180 ° so that a hook-shaped Form is formed. It comprises an inner conductor contact section 7 and an outer conductor contact section 8, which are spaced apart from one another perpendicularly or transversely to the longitudinal axis 6. The contact spring 2 is formed in one piece. It represents a first end 2 a of the contact spring 2. A second end 2 b of the contact spring 2 is formed by the free end of the holding and stabilizing section 3.

In the present exemplary embodiment, the holding and stabilizing section 3 is wider than the connecting section 5 and, in particular, also wider than the contacting section 4. At the transition between the holding and stabilizing section 3 and in the connecting section 5, at least two stop surfaces 3a are formed on the holding and stabilizing section 3, so that the connecting section 5 continues approximately centrally on the holding and stabilizing section 3. The stop surfaces 3a can be brought into contact with a corresponding counter-stop surface within the housing, not shown.

the Figures 2A, 2B , 2C, 2D and 2E show various detailed views of an embodiment of the contact spring 2.

the Figures 3A and 3B show various views of an embodiment of the housing 20. The housing 20 delimits a receiving space 21 which extends along the longitudinal direction 22 of the housing 20. The housing comprises an inner conductor insertion opening 23 on its first end face 20a, via which an inner conductor 50 of a multiple coaxial plug 41 to be short-circuited can be introduced into the receiving space 21 over at least part of its length and brought into electrical contact with the inner conductor contact section 7. The housing 20 also has a laterally aligned outer conductor contact opening 24, the outer conductor contact section 8 of the contact spring 2 passing through the outer conductor contact opening 24 and being able to be brought into contact with an outer conductor 51. This is done on the Figures 5A and 5B referenced, the inserted into the housing 20 Show contact spring 2. Figure 5A shows that the contact spring 2 extends within the receiving space 21 over the major part of the length of the housing 20.

The inner conductor insertion opening 23 and the outer conductor contact opening 24 are separated from one another by a part 25 of the housing 20 and open into the common receiving space 21. In the exemplary embodiment shown, these bearing surfaces 26 are trough-shaped. The inner conductor insertion opening 23 is preferably funnel-shaped and serves as a centering aid for receiving the inner conductor 5150.

The housing 20 comprises an area 27a with a reduced diameter which is surrounded by areas 27b, 27c with an enlarged diameter. A latching wing of the first multiple coaxial plug 40 can engage in the area 27a with the reduced diameter. This prevents the short-circuit pin 1 from falling out of the first multiple coaxial plug 40. At the end of the short-circuit pin 1 there is a further area 27d with an enlarged diameter. The transition to this area 27d serves in particular as a stop which marks an end position of the short-circuit pin 1 when it is inserted into the multiple coaxial plug 40.

In Figure 3B it is shown that the housing 20 of the short-circuit pin 1 has at least one gripping surface 34 on its outside, the gripping surface 34 comprising a flat surface. The gripping surface 34 serves in particular to be able to hold the housing 20 securely in an automated assembly. Alignment in a specific rotational and / or angular position is also possible via the gripping surface 34.

It is also shown that the housing 20 comprises several pairs of openings 29. These pairs of openings 29 are made laterally and / or radially on the housing 20 and are arranged on two opposite sides. When looking at the housing 20 from above, it is therefore possible to see through the housing 20 via respective pairs of openings 29. The pairs of openings 29 are important in the manufacture of the housing 20 in an injection molding process. In this way, auxiliary tools can be introduced to support the tool on both sides which is responsible for the formation of the receiving space 21. In this way it can be avoided that the high pressures with which the liquid plastic is injected into the mold lead to a deformation or to a bending of the tool which creates the receiving space.

These pairs of openings 29 are arranged along the longitudinal direction 22 of the housing 20.

In Figure 2A the second end 2b of the contact spring 2 is shown. This is also the free end of the holding and stabilizing section 3. A corner area 9 of the free end of the holding and stabilizing section 3 at the second end 2b of the contact spring 2 is bent upwards without incisions, thereby forming a locking wing 9. In this context, “free of incisions” can be understood to mean that the latching wing 9 is not notched out on its own, but rather, in particular, is produced completely by embossing. Thus, even with a very small thickness of the holding and stabilizing section 3, a stable latching wing 9 can be produced. The corner area can be shortened compared to the other corner area.

In Figure 6 it is shown how this locking wing 9 is arranged in the housing 20. The housing 20 comprises in particular an additional contact spring insertion opening 28, via which the contact spring 2 can be inserted into the receiving space 21. For this purpose, the housing 20 has a mounting groove 35 at its second end 20b. This is part of the receiving space 21. Due to the curved course of the holding and stabilizing section 3, the mounting groove 35 can be wider and thus made easier. The mounting groove 35 runs horizontally in this case. Another groove 36 crosses the mounting groove 35, preferably forming a right angle. This further groove 36 can have a widened end 36a. Assembly tools for inserting the contact spring 2, for example, can be introduced into this.

The contact spring insertion opening 28 is arranged in the region of a second end face 20b of the housing 20. The contact spring 2 is inserted with its contacting section 4 first into the contact spring insertion opening 28, so that a stable holding of the contact spring 2 on the holding and stabilizing section 3 is possible for the duration of the insertion. The contact spring 2 ends with its second end 2b within the receiving space 21. Referring to FIG Figures 4B and 4C it is shown that a latching opening 30 is made in the housing 20. This is arranged in the region of the second end 20b of the housing 20. The locking opening 30 extends from an outside of the housing 20 into the receiving space 21. An inner wall 31 of the housing 20 within the receiving space 21 in the area of the locking opening 30 comprises a single or multiple angled and / or rounded course. This course corresponds to the slope of the latching wing 9. This ensures that the latching wing 9 can correspondingly "unfold" when it is pushed into the receiving space and securely into the latching opening 30 immersed. As a result, the locking wing 9 can be held in position in spite of the bias. The course of the inner wall 31 increases in the direction of the second end 2b of the housing 2 in the direction of the latching opening 30.

In Figure 2B it is shown that at least the holding and stabilizing section 3 has a curved cross-sectional geometry. As a result, the receiving space 21, which can include a mounting groove for the contact spring 2, can be enlarged in terms of its dimensions, which allows easier manufacture using injection molding technology.

In the Figures 2C and 2D enlarged representations of an embodiment of the contacting section 4 are shown. The outer conductor contact section 8 in Figure 2C comprises a spherical contacting point 8a, as a result of which punctual contacting with the outer conductor 51 is possible. Instead of a spherical contacting point 8a, one can also speak of a bulged contacting point or a bulge that is curved in all directions. As a result, selective and secure contacting of the inner wall of the outer conductor 51 is achieved. Damage to the inner wall of the outer conductor 51 is also avoided, as could happen if burrs or sharp edges are used at the corners. The spherical contacting point 8a slopes down in particular in all directions.

The inner conductor contact section 7, which is shown in Figure 2D can be seen, comprises a line-shaped contact point 7A. In the exemplary embodiment, this extends over the entire width of the inner conductor contact section 7. The linear contact-making point 7a is preferably formed by a bending edge. Line-shaped contacting of the inner conductor 50 is possible as a result.

In Figure 2E a further embodiment of the transition region 10 is shown, which is arranged between the inner conductor contact section 7 and the outer conductor contact section 8. This transition area 10 comprises an indentation 10a, 10b on both sides, which is why the transition area 10 has a width that is smaller than that of the inner conductor contact section 7 and the outer conductor contact section 8. Referring to the enlarged view from FIG Figure 4A which shows the first end 20a of the housing 20, it is shown that the housing 20 has ribs 32 in the area of the outer conductor contact opening 24 which protrude into the outer conductor contact opening 24 and into the indentations 10a, 10b of the transition area 10. As a result, the contacting section 4 of the contact spring 2 is fixed and positioned. The ribs 32 preferably have a increasing course from the second end 20b in the direction of the first end 20a of the housing 20, so that the contacting section 4 is centered accordingly when the contact spring 2 is pushed into the contact spring insertion opening 28.

the Figures 7 and 8th show a three-dimensional view of an embodiment of a plug connection 60 with a first multiple coaxial plug 40 and a second multiple coaxial plug 41.

The first multiple coaxial plug 40 comprises four connections 40a, 40b, 40c, 40d. The short-circuit pin 1 is inserted into the first connection 40a. The remaining connections 40b, 40c, 40d are in Figure 7 left blank for better viewing. In Figure 8 coaxial cables 43 are plugged in. The second multiple coaxial plug 41 likewise comprises at least two connections 41a, 41b, 41c, 41d, wherein according to FIG Figure 8 a coaxial cable 44 is arranged in each connection. Inner conductors 50 and outer conductors 51 are therefore arranged in the respective connections 40a, 40b, 40c, 40d and 41a, 41b, 41c, 41d. The inner conductor 50 in the first connection 40a of the second multiple coaxial plug 41 dips into the inner conductor insertion opening 23 of the short-circuit pin 1 and makes contact with the inner conductor contact section 7 of the contact spring 2.

This is in Figure 9 shown. The outer conductor 51 in the first connection 41a of the second multiple coaxial plug 41 makes contact with the outer conductor contact section 8 of the contact spring 2, as a result of which the inner conductor 50 is electrically conductively connected to the outer conductor 51 and short-circuited. In the embodiment shown, the inner conductors 50 in the respective connections 41a, 41b, 41c, 41d of the second multiple coaxial plug 40 are connected to inner conductors of connected coaxial cables 44. The same applies to the outer conductors 51 in the connections 41a, 41b, 41c, 41d of the second multiple coaxial plug 41. The inner conductors 50 or outer conductors 51 in the further connections 40b, 40c, 40d of the second multiple coaxial plug 41 are simultaneously electrically conductively connected to inner conductors or outer conductors of coaxial cables 43 in the first multiple coaxial plug 40.

Referring to the Figures 10 and 11 a method for producing the short-circuit pin 1 according to the invention is described. In Figure 10 an embodiment of a contact spring belt 70 is shown. This comprises a multiplicity of contact springs 2. Such a contact spring belt 70 is produced in method step S1. Method step S1 comprises sub-method step S1A. In this sub-process step S1A, a metal sheet is punched out. This will be separate contact springs 2 made. Each contact spring 2 comprises a holding and stabilizing section 3, a contacting section 4 and a connecting section 5. The connecting section 5 is arranged between the holding and stabilizing section 3 and the contacting section 4. The contact springs 2 are held together via a common upper connecting strip 71a and a common lower connecting strip 71b. The connecting section 5 of each contact spring 2 is connected to the upper connecting strip 71a and the holding and stabilizing section 3 of each contact spring 2 is connected to the lower connecting strip 71b in the region of its respective free end.

In a further sub-method step S1B, the contacting section 4 is bent into a hook-shaped shape. In this method step, the holding and stabilizing section 3 could also be given its curved shape. A locking wing 9 can also be introduced. The shortening of the locking wing 9 compared to the other corner area can take place in method step S1A.

In a further method step S2, the connecting section 5 is severed from the upper connecting strip 71a. This can take place by means of a punching, cutting and / or laser process.

In a further method step S3, the contact spring 2, which now no longer comprises an upper connecting strip 71a, is inserted into the receiving space 21 of the housing 20 via the contact spring insertion opening 28. The contact spring 2 can be moved towards the housing 20 or the housing 20 towards the contact spring 2.

In a further method step S4, the holding and stabilizing section 3 is separated from the lower connecting strip 71b. This can take place by means of a punching, cutting and / or laser process.

In principle, in the sub-method steps S1A, spacing surfaces could still be left on the upper and lower connecting strips 71a and 71b, which protrude upwards and / or downwards from the respective connecting strips 71a, 71b. In the sub-method step S1b, these spacer surfaces could then be bent over to form spacers 72. The height of these spacers 72 is preferably greater than the height of the contacting section 4 of the respective contact fields 2 which is bent into the shape of a hook.

Additionally or alternatively, in the sub-method step S1A, locking openings 73 could also be made in the upper connecting strip 71a and / or in the lower connecting strip 71b. This is preferably done at the position at which the respective contact spring 2 is arranged. When fitting the housing 2, a corresponding locking device (e.g. via gearwheels) of the pick-and-place machine can intervene in these locking openings in order to align the contact spring 2 safely and precisely so that it can be introduced into the housing 20 with great precision.

The invention is not restricted to the exemplary embodiments described. Within the scope of the invention, all of the features described and / or drawn can be combined with one another as desired.
