Description

  The present invention relates to a contact pin, the contact pin extending substantially parallel to the direction of contact, a contact portion for press-fitting into a contact pin receptacle, a bent portion of the contact pin, and a contact pin transition region And a mounting portion connected to the contact portion. The present invention further relates to a connector having at least one contact pin, the connector having a contact pin receptacle formed from a dielectric, the contact pin receptacle receiving at least one contact pin extending along a press-fit direction. Having at least one axis for. The present invention additionally relates to a method of forming a connector having at least one contact pin held in a contact pin receptacle.

  Contact pins are known in the prior art. The contact portion of the contact pin can serve to connect to a mating contact element such as a bushing or sheath. The mounting portion can serve to make electrical contact with and / or secure the contact pin. For example, the mounting portion can be connected to a circuit board. Using a contact pin having a bent mounting portion, the contact pin can be arranged to be substantially oriented in a direction extending parallel to the circuit board plane. The contact pin is often formed from a rod-shaped piece of material that is first inserted into the contact pin receptacle and then the piece of material is then re-appropriated so that the mounting portion is bent with respect to the contact portion. Formed by molding technique.

  However, a disadvantage of the known contact pins is that reshaping, for example by bending a bar-like piece of material, is an expensive and complicated method, and at the same time it can lead to misalignment between different contact pins. For example, even between two different contact pins formed from the same piece of material using the same method, the transition regions from the mounting portion to the contact portion are different from each other. As a result, the contact pin geometry, and especially the conductive properties of the contact pin in the high frequency region, cannot be accurately reproduced. A further drawback of known contact pins, where the mounting part is bent with respect to the contact part, is that in many cases high-frequency signals can only be transmitted with low signal quality.

  Therefore, the problem of the present invention is that the contact pin can be formed quickly and easily, a good connection between the contact pin and the contact pin receptacle is possible and can be manufactured reproducibly A method of using a connector, contact, and contact pin. In addition, the contact pins should have good transmission characteristics, especially for the high frequency region.

  A contact pin according to the invention of the type described above solves the problem according to the invention because the transition region has a recess that forms a substantially flat engagement surface for the press-fit tool.

  This engagement surface allows a press-fit tool to be used to press-fit a contact pin having an already bent mounting portion into the contact pin receptacle. The engagement surface may be accessible from the outside through the recess. This solution according to the invention eliminates the need to mold the contact pins after they are press-fit into the contact pin receptacles. This has the advantage that the inaccurate bending of the contact pins held in the contact pin receptacles can be avoided. As a result, several contact pins can be reproducibly formed identical to each other. Since the transition region need not be formed by a bending technique, a reproducible and clear transition region or contact pin having a well-defined geometry and conductive properties can be formed. It is advantageous if the contact pins can be pressed into the contact pin receptacles in the contact direction. In this case, the contact direction coincides with the press-fitting direction of the contact pin receptacle. Through this recess, a pressing shoulder having an engagement surface can be formed. The pressing shoulder preferably does not protrude outwardly onto the contact part or the mounting part. At the same time, because of the recesses extending from the outside into the transition region, the disturbance of the impedance trajectory in the transition region is reduced compared to at least a contact pin without a recess. As a result, the high frequency signal contact pins of the present invention can be transmitted with improved signal quality.

  In the case of a connector of the type described above, at least one contact pin is formed by a contact pin according to the invention of the type described above and is at least partially press-fitted into the at least one shaft and retained in this shaft. Thus, the problem according to the present invention is solved. In this case, the connector according to the invention benefits from the above-mentioned advantages of the contact pins according to the invention, in particular because it is not necessary to further mold at least one contact pin after press-fitting.

  In the case of the method according to the invention, at least one contact pin having a contact part extending parallel to the contact direction and a mounting part extending at an angle to the contact part is stamped from the contact material and the punch direction is Since the contact pin and the mounting portion extend perpendicular to the plane extending, the contact pin is press-fitted in the contact direction into the axis of the contact receptacle, and the press-fitting tool engages the engagement surface, thereby solving the problem according to the present invention. Is done. Thus, according to the method according to the invention, the contact pin can be formed first by stamping and its final shape can be obtained. As a result, it is possible to eliminate the molding step after press-fitting into the contact pin receptacle. The recess having the engagement surface allows the press-fit tool to engage the engagement surface and press-fit the contact pin into the contact pin receptacle.

  The solution according to the invention can be further improved by various configurations, each individually advantageous, and these configurations can also be combined with one another if desired. These configurations and their associated advantages will be discussed below.

  According to a first advantageous configuration, the engagement surface can face away from the contact direction. That is, the surface normal on the engagement surface is opposite to the contact direction. As a result, a particularly well transmitted force of the press-fit tool acts on the engagement surface in the contact direction and can consequently act on the contact pin.

  In order to form the engagement surface to be easily accessible by the press-fit tool, the recess frees the engagement surface relative to the rear side of the contact pin opposite to the contact direction.

  The recess can in particular be substantially rectangular. As a result, the contact pin transition region can be formed particularly easily. In addition, good accessibility of the engagement surface can be provided.

  The engagement surface can extend substantially perpendicular to the contact direction. As a result, the engaging press-fit tool can apply a force that extends parallel to the contact direction to the contact pin.

  If the engagement surface is arranged substantially perpendicular to the contact direction and the recess is substantially rectangular, in this case accessible from the rear side of the contact pin, the recess is from the outer end of the transition region It is formed like a rectangular cut that extends into the contact pin. Here, one side of the rectangular shape is formed by the engagement surface, and the surface adjacent to the engagement surface extends in parallel to the contact direction. This shape is particularly advantageous for good transmission of high-frequency signals, as it can at least minimize the interference points in the impedance trajectory that typically occur in the transition region of the part bent with respect to each other. This shape also facilitates press-fitting of the contact pin because the press-fit tool can rest on the adjacent surface.

  The recess can extend into the transition region from above the contact pin located on the opposite side of the mounting portion. As a result, the recess extends into the cross-section of the contact part, and the press-in tool can particularly advantageously apply a force directly on the contact part to press-fit the contact part into the contact pin receptacle.

  The engagement surface can extend from the upper side to at least the center of the cross section of the contact portion. As a result, the force of the press-fit tool acts on the center of the cross-section of the contact portion without applying any force on the contact portion that can cause deformation of the contact portion, so that the contact pin is moved into the contact pin receptacle together with the contact portion. It is possible to achieve press-fitting. The engagement surface preferably extends to 70 ± 5% of the height of the contact portion. This size range for the engagement surface also corresponds to the smooth impedance trajectory required to transmit high frequency signals with low loss and reflection levels. In addition, in order to further improve the press-in process and reduce the risk of the contact pin being skewed during press-fitting, the press-in tool may press on the mounting part, where a force directed in the press-in direction may be applied to the contact pin. it can.

  It is particularly advantageous if the portion of the engagement surface that extends flat perpendicular to the contact direction extends from the upper side to at least the center of the cross section of the contact portion. As a result, it is possible to ensure that a force is applied to the contact part by the pressing tool, and practically to the center of the cross section of the contact part.

  In order to obtain a particularly large engagement surface, the portion of the engagement surface that extends flat perpendicular to the contact direction can extend from the upper side to at least one half of the height of the recess. Is a dimension perpendicular to the contact direction and parallel to the mounting portion.

  It is particularly advantageous if the portion of the engagement surface that extends flat perpendicular to the press-fit direction extends from the upper side to at least two thirds of the height of the recess.

  The depth of the recess can extend from the rear side of the contact pin to the center of the cross section of the mounting portion in the contact direction. As a result, a particularly deep recess can be formed. The deep recess is advantageous for firmly applying the press-fit tool over the recess. In addition, the deep recess is advantageous for the conductive properties of the contact pin according to the invention. The depth of the recess is preferably 70 ± 5% of the depth of the mounting portion. In individual cases, the depth of placement can also be less than 65% of the depth of the mounting portion.

  In order to obtain a particularly small contact pin, the mounting part can extend at right angles to the contact part.

  A particularly simple design contact pin with good conductive properties can be obtained because the contact pin is integrally formed with its mounting part and its contact part.

  According to a further advantageous configuration, the contact pin can be formed as a punched part together with its mounting part and its contact part. As a result, it is possible to dispense with molding steps such as bending of contact pins, for example, and several contact pins with the same properties can be formed. The contact pins can have a rectangular cross section, not only in the transition region but also in the mounting part and / or in the contact part.

  The engagement surface can in particular be formed by a cut surface from punching. In order to form a contact pin according to the invention, it is particularly advantageous if the punching direction extends perpendicular to the mounting part and perpendicular to the contact part.

  The contact pin according to the present invention, which has particularly good conductive characteristics for the high frequency region, has a mounting portion that extends at a right angle to the contact portion, a concave portion that is rectangular, and is perpendicular to the contact direction of the engagement surface. A flat extending portion extends from the upper side to at least one half of the height of the concave portion, and the depth of the concave portion extends from the rear side of the contact pin to the center of the cross section of the mounting portion in the contact direction; This can be obtained because the engagement surface extends perpendicular to the contact direction.

  In order to hold the contact part securely in the contact pin receptacle, the contact part can have at least one mounting projection that projects transversely to the contact direction. The contact part particularly preferably has at least one pair of attachment projections located opposite to each other in a direction transverse to the contact direction. A preferred configuration has two pairs of mounting projections spaced from each other in the direction of contact. The at least one mounting projection can be formed as a barb.

  A connector according to the invention of the type described above can be further improved since the dielectric is formed from a liquid crystal polymer or polyamide. As a result, particularly good conductive properties of the connector according to the present invention can be realized. The dielectric is particularly preferably formed from polyamide PA4T-GF30.

  The contact pin receptacle can have at least one cross-sectional taper along the press-fit direction. In particular, the cross-section taper can be spaced from the end facing the press-fitting direction. Due to the cross-sectional taper, the conductive properties of the connector according to the invention can be improved. The cross-sectional taper can be disposed in a region of the contact pin receptacle where the contact portion of the contact pin is located in the mounted state. In this case, the cross-sectional taper is preferably shorter than the length of the contact portion extending in the press-fitting direction. The cross-sectional taper is particularly preferably shorter than one half of the contact portion.

  The press-fit direction described above preferably coincides with the contact direction of the contact pin according to the present invention.

  The method according to the invention for forming a connector can preferably be used to form a contact pin according to the invention and / or a connector according to the invention according to one of the configurations described above. A substantially rectangular recess can be punched out of the transition area between the contact part and the mounting part, thereby forming an engagement surface extending perpendicular to the contact direction, the engagement surface being the rear side of the contact pin It is accessible from.

  The method according to the invention can be improved in particular because it eliminates the contact pin forming step after the contact pin receptacle has been press-fit.

  The invention will now be described in more detail by way of example using advantageous embodiments with reference to the drawings. Accordingly, by the above, the combination of features shown in the embodiments as an example can be supplemented by additional features for a particular application. Also, according to the above, individual features may be omitted in the described embodiments if the influence of this feature is not important in a specific application.

  In the drawings, the same reference symbols are always used for elements having the same function and / or the same structure.

It is a schematic top view which shows the contact pin by this invention along a punching direction. It is a figure which shows the transfer area | region of the contact pin from FIG. It is a figure which shows the attachment part of the contact pin from FIG. It is a figure which shows the lower side of the contact pin from FIG. 1 is a view showing a contact pin receptacle according to the present invention. FIG. FIG. 6 is a diagram showing simulation results for time interval reflected light measurement on a contact pin according to the present invention compared to a contact pin without a recess.

  FIG. 1 shows a side view of a contact pin 1 according to the invention. In this case, the line of sight is looking at the punching direction S.

  The contact pin 1 has an elongate contact portion 3 extending parallel to the contact direction K, and the elongate contact portion 3 faces the contact direction K at its free end 15. In addition, the contact pin 1 has a mounting portion 5 that bends and extends away from the contact portion 3. The contact part 3 and the mounting part 5 are connected to each other within the transition region 7. The transition area 7 is shown enlarged in FIG. An attachment portion 47 can be disposed between the free end 15 and the transition region 7, which is further described below with reference to FIG.

  The contact pin 1 is preferably formed integrally with the contact part 3 and the mounting part 5. Therefore, the contact part 3 and the mounting part 5 are seamlessly integrated with each other in the transition region 7. In this case, the contact pin 1 is preferably manufactured as a punched part, and the punching direction S of a punching tool (not shown) extends perpendicular to the plane in which the contact part 3 and the mounting part 5 extend. The longitudinal direction M of the mounting part 5 preferably extends perpendicular to the contact direction K. As a result, the mounting portion 5 and the contact portion 3 are orthogonal to each other.

  Hereinafter, the transition region 7 will be described in more detail with reference to FIGS. 1 and 2. In FIG. 1, the transition area 7 is indicated by a circle denoted as A. The transition area 7 has a recess 9. The recess 9 forms an engagement surface 11. The engagement surface 11 serves to apply a press-fit tool to press-fit the contact pin 1 into the contact pin receptacle by its contact portion 3. The engaging surface 11 is accessible from the outside of the contact pin 1 through the recess 9. The engagement surface 11 faces away from the contact direction K. As a result, the press-fit tool can move the contact pin 1 into the contact direction K or apply a force in the contact direction K to the contact pin 1.

  The engaging surface 11 passes through the recess 9 and is free with respect to the rear side 13 of the contact pin 1. The rear side 13 is formed by an end portion 14 of the contact pin 1 that faces away from the contact direction K. Therefore, the free end 15 of the contact portion 3 facing the contact direction K forms the front side 17 of the contact pin 1.

  The recess 9 in the exemplary embodiment shown in the figure has a substantially rectangular shape. The recess 9 preferably extends from the rear side 13 and the upper side 19 of the contact pin 1 into the transition region 7. The recess 9 forms two surfaces in the transition region 7. One of these surfaces is the engagement surface 11 described above. In addition, a guide surface 21 arranged orthogonal to the engagement surface 11 is formed in the contact pin 1 by the recess 9. The guide surface 21 can serve to guide the press-fit tool to the engagement surface 11. Furthermore, the press-fit tool can rest on the guide surface when press-fitted, thereby preventing the tool from sliding off the engagement surface 11. The engagement surface 11 preferably extends perpendicular to the contact direction K. Accordingly, the guide surface 21 in the illustrated embodiment extends parallel to the contact direction K or parallel to the upper side 19.

  A round region 23 can exist between the engagement surface 11 and the guide surface 21. The round region 23 can facilitate the punching of the contact pin 1. In particular, it is possible to avoid having to create a strictly rectangular shape with a generally expensive and complex tapered surface in a punching tool.

  The engagement surface 11 preferably extends into the transition region 7 to the center 25 of the cross section of the contact portion 3. The center 25 of the cross section of the contact portion 3 extends along the contact direction K.

  The flatly extending portion 27 of the engagement surface 11, ie, the portion 27 located outside the round region 23, preferably extends at least to the center 25 of the cross section of the contact portion 3. As a result, a large engagement surface 11 can be formed. In addition, the press-fitting tool applies a force in the contact direction K to the contact pin 1 in this region of the center 25 of the cross section and causes the contact pin 1 to move straight along the contact direction K by its contact portion 3. It is advantageous if possible.

  The flatly extending portion 27 preferably extends from the upper side 19 to at least one half of the height 29 of the recess 9. In this case, the height 29 of the recess 9 starts from the upper side 19 and is perpendicular to the contact direction K. The flatly extending portion 27 particularly preferably extends at least up to two thirds of the height 29 of the recess 9.

  The depth 31 of the recess 9 is a dimension from the rear side 13 to the engagement surface 11 parallel to the contact direction K. The depth 31 of the recess 9 preferably extends to the center 33 of the cross section of the mounting portion 5. The guide surface 21 also has a portion 35 that extends flat. The flatly extending portion 35 is an area located outside the round area 23 in the guide surface. The flatly extending portion 35 of the guide surface 21 preferably extends into the transition region 7 to the center 33 of the cross section of the mounting portion.

  The engagement surface 11 and the guide surface 21 preferably extend the same depth into the transition region 7. That is, the depth 31 of the recess and the height 29 of the recess are the same. As a result, the recess 9 has a square shape.

  The height 37 of the contact portion 3 adjacent to the transition region 7 substantially corresponds to the depth 39 of the mounting portion in the vicinity of the transition region 7. The contact portion height 37 near the transition region 7 is greater than the height 41 at its free end 15 of the contact portion. As a result, the rigidity of the contact portion 3 can be increased in the transition region 7. Similarly, the depth 45 at the free end 43 of the mounting portion 5 is less than the depth 39 near the transition region 7. The depth 45 can be selected, for example, as needed for attachment to the circuit board. The increased depth 39 compared to the depth 45 can have a positive effect on the stability of the contact pin 1.

  The attachment portion 47 of the contact portion 3 will be described below with reference to FIGS. 1 and 3.

  In FIG. 1, the attachment portion 47 is highlighted by a circle indicated by B. The mounting portion 47 can serve to mount the contact pin 1 in the contact pin receptacle. Alternatively, the contact pin can also be formed without a mounting portion. The mounting part 47 has a guide part 49 in which the height of the contact part 3 increases opposite to the contact direction K. In the illustrated embodiment, the guide portion 49 that constitutes the lead-in slope can facilitate the insertion or press-fit of the contact pin into the contact pin receptacle. The guiding part 49 starts from the height 41 of the contact part 3 and extends the height of the contact part to the height 51 of the mounting part.

  Within the mounting part 47, at least one mounting projection 53 can project transversely with respect to the contact direction K. The mounting projections 53 are optional, so that the contact pin 1 can also be formed without these mounting projections 53. In the illustrated embodiment, two mounting protrusions 53 that face each other in the transverse direction with respect to the contact direction K protrude in the transverse direction with respect to the contact direction K. The attachment protrusion 53 can have a reverse shape. For this purpose, the mounting protrusion 53 can first extend opposite to the contact direction K and then extend perpendicular to the contact direction K at the rear end 55.

  The mounting protrusion 53 can serve to penetrate into the material of the contact pin receptacle to securely hold the contact pin 1 within the contact pin receptacle. In this case, for example, it is advantageous if the shaft of the contact pin receptacle has an inner diameter approximately corresponding to the height 51 of the mounting part, so that the mounting protrusion 53 can extend from the mounting part 47 into the material of the contact pin receptacle. It is.

  The contact part 3 shown by way of example can have further mounting protrusions 53 between the mounting part 47 and the free end 15, which are also connected to each other two in a direction transverse to the contact direction K. Located on the opposite side. These mounting protrusions 53 can additionally serve to fix the position of the contact portion 3 within the contact pin receptacle. Additional mounting protrusions 53 are also optional and the present invention is not limited to the presence of mounting protrusions 53.

  FIG. 4 shows the lower side 57 of the contact pin 1 according to the invention. In this case, the line of sight is located parallel to the longitudinal direction M of the mounting portion 5. It can be clearly seen that the contact pin 1 has a continuous uniform thickness 59. The width 59 can be determined by the thickness of the material from which the contact pin 1 is punched. The thickness 59 is preferably equal to the height 61 of the contact part 3 between the mounting part 47 and the mounting projection 53 of the free end 15. Within this region, the contact portion 3 can have a square cross section. The height 41 at the free end 15 of the contact portion 3 can be slightly smaller than the height 61. The contact part 3 is preferably round at its free end 15. In addition, the contact part 3 can have a round cross section at least at the free end 15. The shape of this cross section can be determined by the requirements for the interface.

  FIG. 5 shows a cross-sectional view of an exemplary embodiment of a contact pin receptacle 63 according to the present invention. The contact pin receptacle 63 can in particular be part of a connector. By way of example only, a contact pin receptacle 63 having two shafts 65 for receiving contact pins 1 is shown. FIG. 5 shows the contact pin receptacle 63 in a cross section parallel to the press-fit direction E coinciding with the contact direction K of the contact pin 1 when the contact pin 1 is received in the shaft 65. This sectional view passes through the centers of the two axes 65. By way of example only, schematically shown is a contact pin 1 received towards the top of two axes 65.

  The shaft 65 extends in the longitudinal direction parallel to the press-fitting direction E. In this case, the shaft height 67 can be reduced in the press-fitting direction E. The shafts 65 preferably have insertion openings 71 for inserting the contact pins 1 at their ends 69 facing away from the press-fitting direction E. The height 73 of the insertion opening 71 can correspond at least to the height 51 of the attachment portion of the contact pin 1 as long as the contact pin 1 has the attachment portion 53. The heights 77 at the ends 75 of the shaft 65 facing the press-fitting direction E can substantially correspond to the height 41 of the contact portion 3 at the free end 15. Height 77 is preferably less than height 73. This can result in the aforementioned shaft height 67 decreasing in the press-fitting direction E.

  The contact pin 1 received in the shaft 65 can be securely held in the contact pin receptacle 63 because its mounting projection 53 penetrates into the material 79 of the contact pin receptacle 63. Material 79 is preferably formed from a dielectric such as polyamide or liquid crystal polymer.

  Contact pin receptacle 63 has a maximum height 81. For example, the maximum height 81 exists in the central region 82 when viewed in the press-fitting direction E. In addition, the contact pin receptacle 63 can have a maximum height 81 at the front end 83 facing the press-fitting direction E. The contact pin receptacle 63 can extend from the front end 83 along the press-fitting direction E over the front portion 85 with a maximum height 81. Contact pin receptacle 63 has at least one reduced portion 87 having a low height 89 between central region 82 and forward portion 85. In this case, the low height 89 in the reduced portion 87 is smaller than the maximum height 81. The reduced portion 87 can be formed by a cross-sectional taper 92. The reduced portion 87 is preferably about 3 to 5 times, particularly preferably 4 times larger than the front portion 85 in the press-fitting direction E. Alternatively, the front portion 85 can also have a low height 89. In this case, the reduced portion 87 extends to the front end 83. In a further alternative configuration of the contact pin receptacle 63, it can be assumed that the reduced portion 87 is interrupted at at least one location by an area where the height can correspond to the maximum height 81. As a result, it is possible to form several reduction portions 87 that are vertically aligned with each other in the press-fitting direction E.

  The reduced portion 87 can be formed by the cross-sectional taper 92 as described above. This can be formed because material is removed from the contact pin receptacle 63 in the outer region 91 that surrounds the shaft 65. The depth 93 of material to be removed is preferably one quarter to one sixth of the length 95 of the front portion 85.

  As a result of the reduced portion 87, the line quality of the connector according to the invention can be improved and the impedance trajectory is homogenized. As a result of the recess 9, the contact pin 1 according to the present invention having good transmission quality can be formed quickly and inexpensively by punching the contact pin 1 and press-fitting the contact pin 1 into the contact pin receptacle 63. In particular, it is possible to obtain a connector having good transmission characteristics particularly in the high frequency region.

  FIG. 6 shows the result of the simulation calculation for the time interval reflected light measurement on the contact pin 1 according to the present invention described with reference to FIGS. In this case, the impedance is calculated in response to a pulse with a rise time of 50 picoseconds. For simulation purposes, the contact pin 1 when inserted into the contact pin receptacle 63 according to the invention described with reference to FIG. 5 is calculated and further free of the contact part 3 to generate the actual state. It was assumed that a continuous mating plug (180 ° plug) was connected to the end 15.

  In FIG. 6, curve a shows the simulation results for contact pin 1 described with reference to FIGS. 1-4 in the contact pin receptacle described with reference to FIG. 5, where contact pin 1 has a height of 37 Has a contact portion 3 with a depth of 0.8 ± 0.05 mm and a mounting portion 5 with a depth 39 of 0.8 ± 0.05 mm. In this case, the recess 9 extends into the transition region 7, whereby the height 29 of the recess 9 is 70 ± 5% of the height 37 of the contact portion 3 and the depth 31 of the recess 9 is 70 ± 5% of the depth 39 of 5. These values for depth 39 and height 37 correspond to the preferred embodiment. Other values can be selected according to requirements. In a second advantageous embodiment, the depth 39 and the height 37 are each 1 ± 0.05 mm. Other values are possible. Depth 39 and height 37 are not necessarily the same size.

  The curve b has substantially the same shape as the contact pin 1 according to the invention, but does not have a recess 9 in the transition region 7 and is formed so that the contact part 3 and the mounting part 5 abut against each other at right angles. The simulation result with respect to the made contact pin is shown. In addition, the simulated contact pin of curve b is received in a contact pin receptacle that does not have a reduced portion 87.

  Transition region 7 is located in a time region of about 75-100 picoseconds. It can be clearly seen that curve a has a substantially smaller interference point in the impedance trajectory in this region. Therefore, the contact pin 1 according to the present invention has particularly good conductive characteristics in the high frequency region. In addition, it can be seen in FIG. 6 that the interference points in the impedance trajectory in the region of 200 to 225 picoseconds are significantly reduced for curve b than for curve a. This can be attributed to the optimized contact pin receptacle 63 having a reduced portion 87.
