Technical Field
The invention relates to a contact unit and a method for manufacturing such a contact unit.
Background
Contact units having a plurality of contacts are known, wherein each contact row has contact elements which are identically configured to one another and are arranged in rows spaced apart from one another. In order to position the contact rows, they are injection-molded together with the base plate in a first injection-molding stage, so that the position of the individual contact elements relative to one another is fixed. The base plate together with the contact rows is introduced into an injection mould for the contact housing and finally injection moulded around with the substance for the contact housing. As a result, multiple injection molding processes are required, which are both expensive and time consuming.
The problem of the present invention is to provide an improved contact unit and an improved manufacturing method for manufacturing such a contact unit.

Detailed Description
In the following, reference is made to a coordinate system 5 in the figures, wherein the coordinate system 5 is configured, for example, as a right-handed system. The coordinate system includes an x-axis (longitudinal direction), a y-axis (lateral direction) and a z-axis (vertical direction). Of course, the coordinate system 5 may also be configured differently.
Fig. 1 shows a perspective view of a contact unit 10. The contact unit 10 has a contact housing 15 with a first connection side 20. The contact housing 15 delimits a housing interior 25 (arranged below the drawing plane in fig. 1), wherein the first connection side 20 is arranged, for example, on a side facing away from the housing interior 25.
The contact housing 15 has a contact receptacle 65. The contact receptacle 65 is delimited by a receiving rod 70, for example, in the lateral direction and in the vertical direction. In the longitudinal direction, the contact receptacle 65 is delimited by a housing wall 60, the housing wall 60 having a receiving base 75 on the side facing the first connection side 20.
Another contact unit (not shown) fastened transversely by means of the receiving rod 70 can be inserted into the contact receptacle 65. Furthermore, the contact unit 10 may have a fastening device 80, which fastening device 80 fastens a further contact unit to the contact housing 15.
As an example, the contact unit 10 comprises a first contact row 30. Furthermore, the contact unit 10 comprises, for example, a first contact row 35, a second contact row 35, a third contact row 40 and a fourth contact row 45. The contact rows 30, 35, 40, 45 are stacked one above the other in spaced relation to one another.
The first contact row 30 has a plurality of identically configured first contact elements 55, which are arranged at regular distances from one another in the first row 49, for example on the first straight line 50. The first contact element 55 passes through a housing wall 60 of the contact housing 15, wherein the housing wall 60 separates the first connection side 20 from the housing interior 25. Here, the first contact portions 85 of the contact elements 55 each have a first grid spacing a to the next first contact portion 851。
Each first contact element 55 has a first contact portion 85. Each of the first contact portions 85 of the first contact elements 55 protrudes beyond the receiving base 75 into the contact receptacle 65. In an embodiment, the first contact portions 85 are configured as pin contacts. The first contact section 85 may obviously also be configured as a bushing contact or may be configured differently. As an example, the first contact portion 85 extends in the x direction.
As an example, the first contact portion 85 is arranged running perpendicular to the receiving base 75 and extends in the longitudinal direction. The first contact portions 85 are arranged in parallel at regular intervals with respect to each other in the lateral direction. As an example, the first contact portion 85 is arranged in a first plane 162 (which is configured as an xy plane). The first straight line 50 is oriented perpendicularly to the first contact portion 85 and is likewise arranged in the xy-plane.
In the embodiment, by way of example, the second contact row 35 has a plurality of second contact elements 90 which are identically configured to one another, and the third contact row 40 has a plurality of third contact elements 95 which are identically configured to one another. The fourth contact row 45 has a plurality of fourth contact elements 100 which are identically configured to one another.
Second, third and fourth contact elements 90, 95, 100 are each configured substantially identical to first contact element 55, except for slight deviations.
First to fourth contact elements 55, 90, 95, 100 are each arranged in a second row 119, for example on a second straight line 120, which second straight line 120 runs in the xz-plane. As an example, the second line 120 is arranged perpendicular to the first line 50.
Furthermore, the second contact portions 105 are each arranged in a third row 124 at regular intervals with respect to one another, for example on a third straight line 125 in the xy-plane.
The second contact portions 105 are each arranged at a second grid spacing a from the next second contact portion 1052To (3). Second grid interval a2A distance a from the first grid1The same is true.
Furthermore, the third contact portions 110 are each arranged at regular intervals relative to one another in a fourth row 126, for example on a fourth straight line 127 in the xy-plane. Furthermore, the fourth contact portions 115 are each arranged in a fifth row 128 at regular intervals with respect to one another, for example on a fifth straight line 129 in the xy-plane.
In the embodiment, by way of example, the first recess row 130 is arranged in the housing wall 60 between the second contact row 35 and the third contact row 40 in the vertical direction.
The first recess row 130 is arranged in a second plane 161, which second plane 161 is configured, for example, as an xy-plane. The second plane 161 is arranged parallel to the first plane 162. The first recess row 130 has a plurality of first recesses 135, and each of the first recesses 135 is configured to be identical to each other. The first recesses 135 have a third grid spacing a relative to each other3. As an example, each first recess 135 has a rectangular cross section. Each first recess 135 extends in the longitudinal direction and is arranged to run parallel to the contact portions 85, 105, 110, 115. For example, the first recesses 135 of the first recess row 130 are respectively arranged in the lateral direction between two adjacently arranged contact portions 85, 105, 110, 115, but are arranged offset from the contact portions 85, 105, 110, 115 in the vertical direction, such that the first recesses 135 are arranged obliquely offset upwards from the second contact portions 105 in fig. 1. Each of the first recesses 135 is preferably arranged centrally between the two contact portions 85, 105, 110, 115 of the contact rows 30, 35, 40, 45. In the vertical direction, the first recess 135 is delimited by the housing wall 60.
As an example, the first recesses 135 are each delimited in the transverse direction by a delimiting bar 140 of the contact housing 15. The delimiting rod 140 is arranged above the contact portions 85, 105, 110, 115 on the second line 120. If the delimiting bar 140 and the contact portion 85, 105, 110, 115 are projected in the z-direction in the xy projection plane, the delimiting bar 140 and the contact portion 85, 105, 110, 115 overlap in the xy projection plane.
Above the first recess row 130, as an example, a guide bar 145 may be arranged between the third contact row 40 and the first recess row 130, which protrudes into the contact receptacle 65 and serves to guide the further contact unit when it is introduced into the contact receptacle 65 and to prevent the further contact unit from tilting.
Above the guide bar 145, the third contact portion 110 of the third contact row 40 protrudes beyond the receiving base 75. The fourth contact row 45 is arranged above the third contact row 40. Above the fourth contact row 45, for example, between the fourth contact row 45 and the receiving bar 70, a second recess row 150 is arranged, which has a plurality of second recesses 155, which are configured identically to one another. The second recesses 155 are arranged in a sixth row 156 on a sixth straight line 157. The sixth row 156 is preferably arranged parallel to the first through fifth rows 49, 119, 124, 126, 128. As an example, the second recess row 150 is arranged on a side of the fourth contact row 45 facing away from the first recess row 130.
The second recess 155 may be configured the same as the first recess 135. The second recess 155 may also be configured differently from the first recess 135.
The second recess 155 extends through the housing wall 60 in a longitudinal direction parallel to the x-axis and has, for example, a rectangular cross-section. For example, the extension of the second recess 155 in the vertical direction is greater than the extension of the first recess 135 in the vertical direction.
Both the first recess 135 and the second recess 155 are arranged in a common third plane 160. As an example, the third plane 160 is configured as an xz plane. As a result, the second recesses 155 (which are arranged offset upwards in the vertical direction towards the fourth contact portions 115, for example offset on the side facing away from the third contact row 40) are also arranged between two fourth contact portions 115 in the transverse direction, respectively.
In the embodiment, as an example, the first recess 135 and the second recess 155 are free and configured as through openings. Here, free is understood to mean that no further components are arranged in the first recess 135 or the second recess 155, which means that a channel fluidly connecting the surrounding area 170 to the housing interior 25 is formed via the first recess 135 and the second recess 155. The first recess 135 and/or the second recess 155 may also be at least partially filled with a substance 171.
By providing the recesses 135, 155, the weight of the contact unit 10 can be minimized. Furthermore, it is ensured that, in a production method, the number of method steps for producing the contact unit 10 is particularly small. Furthermore, by providing the recesses 135, 155, the contact housing 15 can be manufactured in a single injection molding process with a homogeneous substance 171, for example a plastic, in particular a thermoplastic.
In fig. 1, the contact portions 85, 105, 110, 115 and the recess rows 130, 150 are arranged on straight lines 50, 120, 125, 127, respectively. Of course, the recess rows 130, 150 may also be arranged on another contour, for example in a curved shape.
Fig. 2 shows a perspective view of the contact rows 30, 35, 40, 45 shown in fig. 1.
Hereinafter, as an example, the first contact element 55 of the first contact row 30 is explained. Second through fourth contact elements 90, 95, 100 are configured substantially identically to first contact element 55, wherein the extension of respective second through fourth contact elements 90, 95, 100 is configured differently from first contact element 55.
The second connection portion 180 is obliquely arranged with respect to the first connection portion 175. The second connection portion 180 is preferably arranged at right angles to the first connection portion 175. The first contact portion 85 and the first connection portion 175 are aligned, meaning that the first connection portion 175 is also disposed in the first plane 162. The fifth contact portion 185 is also aligned with the second connection portion 180. In the embodiment, as an example, the second connection portion 180 is configured to be longer than the first connection portion 175.
The first widened portion 190 is transversely arranged on the second connection portion 180. As an example, the first widened portion 190 is directly adjacent to the fifth contact portion 185.
The first widened portion 190 has a first bearing surface 195 on a side facing the first connection portion 175. The first support surface 195 is arranged parallel to the first connection portion 175. Furthermore, the first bearing surface 195 extends, for example, in the xy-plane. In addition, a first widened portion 190 is arranged on a side of said second connection portion 180 facing away from the first connection portion 175. The first connection portion 190 may also be disposed at both sides of the second connection portion 180. It is also possible to provide only one first widened portion 190 at the first connection portion 175.
Instead of the above-described planar configuration of the first support surface 195, the first support surface 195 may also be configured as a curve, such as a semi-circle.
The side surface 200 of the second connection portion 180 extends planarly above the second connection portion 180 and above the first connection portion 190.
A second widened portion 205 is additionally provided at the second connection portion 180 of the first contact member 55 and the second contact member 90. The second widened portion 205 is preferably configured substantially identical to the first widened portion 190. The second widened portion 205 has a second support surface 210 on the side facing the first connection portion 175. By way of example, the second support surface 210 is configured as an xy-plane and oriented parallel to the first support surface 195. The second connecting portion 180 is configured to be slimmer between the first widened portion 190 and the second widened portion 205 than at the widened portions 190, 205.
In the case of a longer configuration of the second connection portion 180 of the first contact element 55 and/or the second contact element 90 in the z-direction, further widened portions 190, 205 may be provided at the contact elements 55, 90. It is also contemplated that the widened portions 190, 205 are configured as lateral notches in the second connection portion 180.
FIG. 3 shows cuts from a plan view of the stabilization cores 215, 250;
the stabilizing cores 215, 250 have a first core portion 220 and a second core portion 225. The second core portion 225 is configured like a rake and has, for example, engaging elements 230, the engaging elements 230 being arranged at a regular third grid spacing a3And each of which is bounded by a gap 235. The engaging element 230 extends in a longitudinal direction. Each engagement element 230 has a rectangular configuration in cross-section corresponding to the recesses 135, 155. The first core section 220 is configured substantially like a plate, wherein the joining elements 230 are each connected to the first core section 220 by a fixed end 240 in a longitudinal direction adjacent to the first core section 220. It is also contemplated that the engagement elements 230 have different cross-sections, such as polygonal, circular, or elliptical cross-sections. The support surfaces 195, 210 are correspondingly configured to correspond to the upper configuration of the engagement element 230.
Fig. 4 shows a flow chart of a manufacturing method for manufacturing the contact unit 10. Fig. 5 shows a perspective view of the contact unit 10 after the third method step 310, and fig. 6 shows a sectional view through the contact unit 10 along the cutting plane a-a shown in fig. 1 after the fifth method step 315. Fig. 7 shows a cut from a sectional view through the contact unit 10 during a seventh method step 330.
In a first method step 300, an injection mold 245 (schematically illustrated in fig. 6 by a dashed and dotted line), a first stabilizing core 215 and advantageously a second stabilizing core 250 and at least one contact row 30, 35, 40, 45 are provided.
In a second method step 305, at least a first contact row 30, in this embodiment four contact rows 30, 35, 40, 45; as an example, they are positioned in a predetermined first position in the interior 265 of the injection mould 245 and are held by the holding device 260. The holding device 260 may partially grip and fix the respective contact element 55, 90, 95, 100 of the contact row 30, 35, 40, 45, for example at the fifth contact portion 185. For example, the holding device 260 may be configured as a clamp. For each fifth contact portion 185, the jig may have a recess in which the fifth contact portions 185 are respectively disposed. The holding device 260 holds all four contact rows 30, 35, 40, 45.
In a third method step 310 (see fig. 5), the catch core 255 is positioned in the interior 265 in a second predetermined position. Further, in a third method step 310, the first stabilizing core 215 and the second stabilizing core 250 are located at third and fourth predetermined positions, respectively.
In an embodiment, for example, both stabilizing cores 215, 250 are inserted deep into the interior 265 in the longitudinal direction such that the free ends 270 of the engagement elements 230 of the stabilizing cores 215, 250 strike the catch core side surfaces 280 of the catch core 255. The free end 270 may be disposed spaced from the catch core side surface 280, or only one of the two stabilizing cores 215, 250 may rest against the stabilizing core 215, 250 through the free end 270.
It is also conceivable that receiving holes arranged on the side facing the stabilizing cores 215, 250 are provided in the catch core 255. Preferably, one receiving hole is provided for each stabilizing core 215, 250. The receiving holes correspond to the stabilizing cores 215, 250 at the free end 270. The receiving openings can be configured in a groove-like manner extending in the y direction in their main direction of extension. One receiving hole may also be provided for each engagement element 230, respectively, which receiving holes are arranged in a row next to each other in the y-direction. The stabilizing core 215, 250 is additionally supported at the free end by dipping the stabilizing core 215, 250 into the receiving hole.
In this case, the stabilizing cores 215, 250 are inserted into the interior 26 such that the stabilizing cores 215, 250 engage the joining element 230 and carry the contact rows 30, 35, 40, 45 respectively between two adjacently arranged second connection portions 180 of the contact rows 30, 35, 40, 45 (see fig. 5). The first widened portion 190 is arranged above the upper side 275 of the engaging element 230 of the first stabilizer core 215. The second widened portion 205 is arranged between the engagement elements 230 of the first stabilizing core 215 and the engagement elements 230 of the second stabilizing core 250, and is therefore arranged above the second stabilizing core 250. Since the rows of contacts 30, 35, 40, 45 are held by the stabilizing cores 215, 250, the holding device 260 may be removed. In this case, the stabilizing core 215, 250 supports at least one force (e.g., gravity, but also acceleration forces) from the contact element 55, 90, 95, 100. As a result of the passage through the first contact row 30 and the second contact row 35 by engaging the portions 230 of the two stabilizing cores 215, 250, tilting of the first contact element 55 and the second contact element 90 of the first contact row 30 and the second contact row 35 can be reliably avoided.
If the widened portions 190, 205 are configured as transverse recesses in the second connecting portion 180, the engagement elements 230 can pass through the recesses in order to support the contact elements 55, 90, 95, 100.
Furthermore, a stabilizing device 290 (indicated by a dashed line in fig. 5) may be provided, for example, which is arranged above and/or below one of the first to fourth contact portions 85, 105, 110, 115. The stabilizing device 290 may be configured in the shape of a bar, and its main extension direction extends in a lateral direction. The stabilizing device 290 secures the contact rows 30, 35, 40, 45 against tilting about the y-axis when the engagement element 230 is inserted between the contact elements 55, 90, 95, 100. The stabilization device 290 may be removed if, for example, the contact element 230 is partially engaged between the contact rows 30, 35, 40, 45.
In a fourth method step 315 (see fig. 6), the injection-moldable substance 171 of the contact housing 15 is injected into the injection mold 245. Fluid substance 171 surrounds first connection portion 175 and second connection portion 180 of contact elements 55, 90, 95, 100 and forms a material-bonded connection with contact elements 55, 90, 95, 100. The injection mould 245 is configured such that the fifth contact portions 185 of the contact rows 30, 35, 40, 45 remain free and are not injection moulded around with the substance 171 in order to form the second connection side 281 of the contact unit 10 on the inside of the contact housing 20. For example, substance 171 may be a thermoplastic. Substance 171 is injected into injection mold 245 at a temperature above its melting temperature (within the process temperature range).
In a fifth method step 320, the first part 282 of the substance 171 is hardened, for example, in the first region 296. Hardening of first portion 282 may be performed by cooling substance 171 below its melting temperature (and glass transition temperature), such as in first region 296. First region 296 is bonded to side surface 297 of injection mold 245. First portion 282 may be, for example, 30 to 60 mass percent of substance 171. The first portion 282 stabilizes the position of the contact rows 30, 35, 40, 45. Furthermore, during the hardening of the first portion 282 of the substance 171, the first predetermined position of the contact rows 30, 35, 40, 45 and their contact elements 55, 90, 95, 100 is fixed by the stabilizing cores 215, 250. In particular, a possible sagging of the contact elements 55, 90, 95, 100 is ensured, for example, when the injection mold 245 is moved, by the bearing surfaces 195, 210, which bearing surfaces 195, 210 bear on the respective facing upper sides 275 of the stabilizing cores 215, 250. In this case, at least one force, for example a force resulting from acceleration or gravity, may be supported. Furthermore, the two stabilizing cores 215, 250 prevent tilting, in particular of the first contact row 30 and the second contact row 35. Since the second connection portion 180 stops on the engagement element 230, the contact elements 55, 90, 95, 100 are also prevented from twisting about the y-axis.
In a sixth method step 325, after the first part 282 of the substance 171 has hardened, the stabilizing cores 215, 250 are removed.
In a seventh method step 330 (see fig. 7), a second portion 283 of the substance 171 is not hardened, at least in a second region 298 arranged in the interior 265 spaced apart from the side surface 297 of the injection mould 245, which means that the substance 171 is fluid in the second region 283. In second region 283, the temperature of substance 171 remains locally above the glass transition temperature and/or the melting temperature.
By withdrawing the stabilizing wicks 215, 250, the fluid second portion 283 of the substance 171 flows into the recesses 135, 155 and partially (preferably completely) fills the recesses 135, 155. In particular, by hardening of first portion 282 of mass 171, skin 285 is formed during resting against joining element 230. Skin 285 may be interrupted at second portion 283 and may also be determined after second portion 283 of mass 171 flows into pockets 135, 155. The recesses 135, 155 are sealed by the flow of the second portion 283. Furthermore, a particularly light weight of the contact housing 15 is ensured.
Furthermore, to increase the volume of second portion 283 of substance 171, after first portion 282 hardens, additional fluid substance 171 may be fed into injection mold 245 in order to accelerate the flow of second portion 283 into recesses 135, 155 and/or in order to compensate for the shrinkage of the first portion during hardening/cooling.
In an eighth method step 335, second portion 283 of substance 171 is further hardened until substance 171 is completely hardened and always has a temperature below the glass transition temperature and/or the melting temperature.
In a ninth method step 340, the catch core 255 is removed and the contact unit 10 is removed from the injection mold 245.
As an alternative to the fifth through seventh method steps 320-330 described above, the stabilizing cores 215, 250 may remain in the injection mold 245 until the substance 171 is substantially completely hardened and the substance 171 does not flow into the recesses 135, 155 when the stabilizing cores 215, 250 are removed.
As an alternative to the assembly of the stabilizing cores 215, 250 described above in the second method step 305 and the third method step 310 (with the contact rows 30, 35, 40, 45 in the injection mold 245), the first position in the second method step 305 (in which the contact rows 30, 35, 40, 45 are positioned by the holding device 260) can also be outside the injection mold 245.
In an alternative third method step 310, the stabilizing core 215, 250 is positioned relative to the contact row 30, 35, 40, 45 such that the stabilizing core 215, 250 is introduced in a linear movement, wherein the joining element 230 is located between the two contact elements 55, 90, 95, 100.
The stabilizing cores 215, 250 are driven to opposite end positions compared to the contact rows 30, 35, 40, 45. In the opposite predetermined end position, the stabilizing cores 215, 250 and the contact rows 30, 35, 40, 45 are correctly positioned relative to one another for subsequent injection molding with the substance 171 therearound (see fourth method step 315). In this case, in the opposite end position, the gap base 295 of the gap 235 of the first stabilizing core 215 can bear frontally against the side surface 200 of the second connection portion 180 of the fourth contact element 105. Similarly, the gap base 295 of the gap 235 of the second stabilizing core 250 can bear frontally against the side surface 200 of the second connection portion 180 of the second contact element 90. Furthermore, in the opposite end position, the gap base 295 of the gap 235 of the first stabilizing core 215 can have a predetermined first spacing from the side surface 200 of the second connecting portion 180 of the third contact element 95 on the front side and the gap base 295 of the gap 235 of the second stabilizing core 250 can have a predetermined second spacing from the side surface 200 of the second connecting portion 180 of the first contact element 55.
In an additional method step 311 following the third method step 310, the retaining device 265 is removed and the contact rows 30, 35, 40, 45 are retained by the stabilizing cores 215, 250. Further, the rows of contacts 30, 35, 40, 45 are driven into the interior 265 of the injection mold 245 with the stabilizing cores 215, 250 until the first stabilizing core 215 is in the second predetermined position and the second stabilizing core 250 is in the third predetermined position, and preferably stopped on the catch core 255 or dipped as described above.
The subsequent method steps are the same as the method steps described above.
This configuration has the advantage that, on the one hand, a pressure equalization between the housing interior 25 and the surrounding region 170 can be ensured, and, on the other hand, it has a particularly high form stability.
