Description

[Technical field]

[0001] The present invention relates to a shielded connector, in particular an SMD connector (surface mounted device), having a connector housing and a shield plate. [Background technology]

[0002] The connector is used, for example, for contacting a circuit board. The connector comprises a housing and a number of contact elements arranged therein. The housing comprises a plug opening, which makes the contact elements accessible and contactable. A component to be connected to the circuit board comprises a mating connector, which is inserted into the plug opening of the connector. The connector comprises a shield plate for shielding the shielded connector from external electromagnetic influences and / or for preventing electromagnetic radiation from penetrating from the connector into the environment. Usually, two shield plates are provided, which are arranged on long sides of the connector housing arranged opposite each other. At least one of these shield plates is then arranged on the inside of the connector housing facing the contact elements.

[0003] EP 1 251 591 A2 describes a connector having a shield plate, which is connected to the connector housing via a latch connection, in particular the latch connection being configured as a latch hook which engages in a recess in the connector housing.

[0004] However, such recesses are not designed for the spring contact elements and would hinder their deflection. In addition, the latch hooks protrude beyond the connector housing. As a result, they are exposed to external mechanical influences. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a fastening of spring contact elements of a shield plate in a connector housing. [Means for solving the problem]

[0006] The connector includes a connector housing and contact elements disposed within the connector housing, the connector housing having a plug opening on one side through which a mating connector can be inserted to contact the contact elements.

[0007] In addition, the connector comprises one or more shield plates for shielding, at least one shield plate being arranged inside the connector housing, the shield plate comprising at least one spring contact element arranged on a side of the shield plate facing towards the plug opening, each spring contact element comprising at one end a fastening element facing towards the plug opening.

[0008] In addition, at least one spring contact element is pretensioned in the direction of the interior of the connector, so that the spring contact element is arranged as close as possible to the contact element and can be pushed outward by the mating connector when the mating connector is plugged in.

[0009] The connector housing comprises at least one recess in the housing wall on the side of the plug opening. The at least one recess is preferably arranged on the edge of the connector housing around the plug opening. In particular, the connector housing has as many recesses as the shield plate has spring contact elements with fastening elements. The recesses comprise at least one web on the side facing the inside of the connector, i.e. on the inside. The at least one fastening element of the at least one spring contact element engages in the at least one recess but is not fixed there and is outwardly movable in at least one, preferably exactly one, direction (in addition to the insertion direction), particularly preferably in a direction perpendicular to the housing wall. As a result, the spring contact element can be deflected without the fastening hindering deflection or without the fastening being released by deflection.

[0010] In the non-plugged state of the connector, i.e. when the counter connector is not plugged in, the at least one fastening element abuts against the outer side of the at least one web, i.e. the side facing away from the interior of the connector. The at least one web prevents the at least one spring contact element from moving or falling out into the interior of the connector, i.e. towards the center of the connector. Even during the plugging process, if the counter connector is simply in contact with the at least one spring contact element, the at least one web further prevents the at least one spring contact element from moving or tilting into the interior of the connector.

[0011] If the counter connector is then further plugged into the connector, this deflects the at least one spring contact element outward. Due to the deflection of the at least one spring contact element, the at least one fastening element in the corresponding recess moves away from the at least one web and separates from the at least one web in the plugged-in state of the connector, i.e. when the counter connector is fully plugged into the connector. The at least one fastening element is configured not to protrude from the at least one recess. The at least one fastening element and the at least one recess match each other in such a way that the fastening element does not protrude outward beyond the connector housing in the direction opposite to the plug-in direction, in particular not in the maximum deflection state of the spring contact element. As a result, the installation space for the connector is not increased by fastening.

[0012] The spring contact elements, which are spring-mounted and hooked into recesses in the connector housing that allow their movement, result in a stable retention of the spring contact elements, which are not likely to fall out inwards, but at the same time can only move outwards, i.e. to the extent that they do not protrude from the connector housing. As the spring contact elements do not protrude from the connector housing, the risk of bending due to external mechanical influences in any direction is significantly reduced.

[0013] At least one spring contact element may comprise an arch portion which extends from the inside around the web. In particular, the arch portion extends over the web in the opposite direction to the plug-in direction. The fastening element is arranged at the end of the arch portion. The fastening element may here be configured as a fastening hook which engages behind the at least one web in the recess. In this case, a single web may be used which extends over the entire length of the recess.

[0014] Alternatively, the spring contact element may comprise an angled fastening element, in particular with at least one angled portion bent at an angle of 90°. The angled fastening element extends into the recess and engages with at least one of its bent portions behind at least one web. In this case, the web does not extend over the entire length of the recess, so that the angled fastening element is guided into the recess through a gap between two webs or through a gap between a web and the housing wall.

[0015] According to an advantageous embodiment, the bent fastening element is configured as a T-shaped fastening element with two oppositely bent parts. Preferably, each of the bent parts engages behind the web. This ensures a stable hold, in particular against the fastening element being twisted off. In principle, only one of the bent parts may engage behind the web.

[0016] According to another advantageous embodiment, the bent fastening element may be configured as an L-shaped fastening element with a bent portion. The bent portion engages behind the web. Here, several L-shaped fastening elements, in particular of different spring elements, may be bent alternately in opposite directions. This ensures a stable hold, in particular against unscrewing. The L-shaped fastening elements may each be bent in the same direction. Fastening elements of the same configuration can be manufactured consecutively and easily and regardless of the number of spring elements.

[0017] When the connector is plugged in, i.e. when the at least one spring contact element is thus deflected, preferably at least a part of the at least one spring contact element abuts against the inside of the at least one web or against the inside of the connector housing. This limits the outward movement of the at least one spring contact element and the corresponding fastening element. The distance perpendicular to the housing wall between the outside of the fastening element and the point at which the at least one spring contact element abuts against the at least one web or against the connector housing preferably corresponds to the thickness of the connector housing. In this case, even at maximum deflection of the spring contact element, the fastening element remains in the recess of the connector housing. At the same time, the fastening element can move as far as possible in the recess and thus the spring contact element can be deflected as far as possible.

[0018] The second fastening of the shield plate is achieved in that the shield plate rests on a positioning element, which is preferably arranged on the side where the connector is connected to an electronic component, in particular a circuit board.

[0019] The positioning element is in particular a fastening shoulder, on which the connector housing has a projection extending parallel to the housing wall. The shield plate is curved at the fastening shoulder according to the shape of the fastening shoulder and rests on the fastening shoulder by at least a part of the curve. The fastening shoulder preferably extends over the entire width of the connector housing, and the shield plate rests on the fastening shoulder along its entire width.

[0020] Alternatively or additionally, the positioning element may be at least one support protruding from the connector housing wall in the direction towards the center of the connector, in particular perpendicular to the connector housing wall. The shield plate comprises at least one recess into which the at least one support can be inserted so that the shield plate rests on the at least one support. The support may optionally comprise an opening into which the elongated portion of the shield plate can engage.

[0021] The shield plate preferably includes at least one solder pad where the shield plate is soldered to the circuit board, which forms both a mechanical and electrical connection between the shield plate and the circuit board.

[0022] Embodiments of the invention are illustrated in the drawings and are explained in more detail in the following description. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] FIG. 1 shows an isometric view of a first embodiment of a connector 1 according to the invention, fastened to a circuit board 2 as an SMD (surface mounted device). The connector 1 comprises a number of contact elements 3, which are contacted via the circuit board 2. In addition, the connector 1 comprises a connector housing 10, which comprises on its upper side, arranged opposite the circuit board, a plug opening, which makes the contact elements 3 accessible from the outside. Two shield plates 4 and 5 are provided in the connector 1. The shield plates 4, 5 consist of a metal or a metal alloy, such as copper sheet, and have in the contact area a metal coating suitable for electrical contacts, such as palladium. In the soldering area, the shield plates 4, 5 preferably have a tin coating. The first shield plate 4 is arranged on the front outside of the connector housing 10 and will not be described in more detail here. The second shield plate 5 is located on the inside rear of the connector housing 10. It is retained in the connector housing 10 via a number of fastening hooks 53 in this first embodiment. The second shield plate 5 will be described below with reference to Figures 2 and 3. Identical elements are identified with the same reference numbers and will be described only once below.

[0025] Figures 2 and 3 show isometric cross-sectional views of the connector 1 along the section line XX in Figure 1. In Figure 2, the connector 1 is shown in an unplugged state, i.e. no mating connector is plugged in. In Figure 3, the connector is shown in a plugged-in state, i.e. a mating connector is plugged into the connector 1 through the plug opening and contacted by the contact elements 3, but for reasons of clarity the mating connector itself is not shown. In this embodiment, the mating connector may be configured similarly to the connector 1.

[0026] The second shield plate 5 comprises a base 50. A number of spring contact elements 51 are arranged at this base 50 towards the top, which in this embodiment have a triangular shape. The spring contact elements 51 are pretensioned inwards in the direction of the connector centre, i.e. towards the contact element 3, and protrude in this direction from the connector housing 10, forming a curved edge towards the base 50. At their upper end in the direction of the plug opening, each spring contact element 51 comprises an outwardly curved arch section 52. A fastening hook 53 is formed at the end of the arch section 52 and points downwards in the direction of the circuit board 2. The base 50 of the second shield plate 5 abuts against the rear connector housing wall 11 of the connector housing 10. In this embodiment, the housing wall 11 is formed straight and has two substantially parallel faces, on the inside and the outside, between which a thickness d of the housing wall 11 or the connector housing 10 is defined. At an upper outer edge 12 surrounding the plug opening, the connector housing wall 11 comprises a number of recesses 13. The number and positions of the recesses 13 correspond to the number and positions of the spring contact elements 51. Each recess 13 comprises an upwardly projecting web 14 on its inside. The web 14 is shorter than the connector housing wall 11 and does not reach the outer edge 12 of the connector housing 10.

[0027] The following description is based on an exemplary spring contact element 51 of the second shield plate 5 and a corresponding recess 13 in the connector housing 10. An arch portion 52 extends from an end of the spring contact element 51 from the interior of the connector 1 and extends beyond the web 14 into the recess 13 such that the fastening hook 53 protrudes beyond the web 14 to engage into the recess 13. The arch portion 52 does not protrude beyond the outer edge 12.

[0028] 2, the fastening hooks 53 are pressed against the web 14 due to the pretension of the spring contact elements 51, with their inner sides abutting against the outer sides of the web 14. This realises a first fastening of the shield plate 50, which prevents the spring contact elements 51 from tilting inwards.

[0029] Further, Figures 2 and 3 show a circuit board 2 with various soldering points 20, 21, 22. The contact element 3 is soldered to the first soldering point 20, thereby establishing an electrical and mechanical connection to the circuit board 1. The first soldering point 20 for data transmission is contacted at or inside the circuit board 2. The second soldering point 21 and the third soldering point 22 are contacted so that shielding can take place through them. The first shield plate 4 is soldered to the second soldering point 21 via a soldering pad 44 on the underside.

[0030] The connector housing 10 comprises a fastening shoulder 15 protruding from the rear connector housing wall 11 and extending parallel thereto over the entire width of the housing wall 11. The base 50 of the second shield plate 5 rests downwards on the fastening shoulder 15 of the connector housing 10 and curves according to the shape of the fastening shoulder 15. In addition, the second shield plate 5 comprises a number of soldering pads 54 arranged on the curved part of the base 50 and extending downwards through the first openings of the fastening shoulder 15. The soldering pads 54 are each soldered to a third soldering point 22 of the circuit board 2. This firstly realizes an electrical contact between the second shield plate 5 and the circuit board 2 and secondly realizes the fastening of the second shield plate 5 to the circuit board 2 and to the connector housing 10. In addition, the second shield plate 5 comprises elongated portions (not shown here) between the soldering pads 54 which engage in second openings of the fastening shoulders 15 - see the description of the second embodiment in this regard - this forms an additional fastening of the second shield plate 5 to the connector housing 10.

[0031] In the plugged-in state shown in FIG. 3, the spring contact element 51 of the second shield plate 5 is deflected by the mating connector (not shown) and abuts against the inside of the connector housing wall 11. In this embodiment, the arch portion 52 of the spring contact element 51 abuts against the inside of the web 14 at least at point P. The fastening hook 53 moves outward in the recess 13. The arch portion 52 is configured such that the distance perpendicular to the surface of the housing wall 11 between the outside of the fastening hook 53 and point P corresponds to the thickness d of the housing wall 11. Even when the spring contact element 51 abuts against the connector housing 10, the fastening hook 53 remains in the recess 13 and does not protrude from the connector housing 10. The distance a minus the thickness of the web 14 and the thickness of the fastening hook 53 corresponds to the maximum deflection of the spring contact element 51 in the direction of the center of the connector.

[0032] FIG. 4a shows an isometric view of a second embodiment of a connector 100 according to the invention, fastened to a circuit board 2 as an SMD (surface mounted device). FIG. 4b shows a detailed view of part IV of FIG. 4a. The connector 100 likewise comprises a number of contact elements 3, which are contacted via the circuit board 2. In addition, the connector 100 comprises a connector housing 110, which comprises on its upper side, arranged opposite the circuit board, a plug opening, which makes the contact elements 3 accessible from the outside. Two shield plates 4 and 105 are provided in the connector 1. The second embodiment differs from the first embodiment in the fastening of the second shield plate 105. The circuit board 2 with the soldering points 20, 21, 22, the contact elements 3 and the first shield plate 4 as well as their contacts correspond to the first embodiment, see the above description.

[0033] The second shield plate 105 is arranged on the rear inside of the connector housing 110. In this second embodiment, it is held in the connector housing 110 via a T-shaped fastening element 153. The connector housing wall 11 comprises a number of recesses 113. Each recess 113 on the inside comprises two upwardly projecting webs 114a and 114b, one of the two webs 114a being arranged on the right hand side of the recess 113 and the other web 114b being arranged on the left hand side of the recess 113. Between the webs 114a, 114b there is a gap through which the T-shaped fastening element 153 is guided into the recess 113. The T-shaped fastening element 153 comprises two bends. Each bend engages behind one of the webs 114a, 114b.

[0034] Figures 5 and 6 show isometric cross-sectional views of connector 100 along section line YY in Figure 4a. Connector 100 is shown in an unplugged state in Figure 5 and in a plugged state in Figure 6, with the mating connector not shown for reasons of clarity. In this embodiment, the mating connector may be configured similarly to connector 100.

[0035] The second shield plate 105 comprises a base 150. A number of spring contact elements 151 are arranged at this base 150 towards the top, which in this embodiment have a triangular shape. The spring contact elements 151 are pretensioned inwards in the direction of the center of the connector, i.e. towards the contact element 3, and protrude in this direction from the connector housing 110, forming a curved edge towards the base 150. At their upper end in the direction of the plug opening, each spring contact element 151 comprises a curved part 152 that curves outwards. A T-shaped fastening element 153 is formed at the end of the curved part 152. Due to the cross section, only the bent part of the T-shaped fastening element 153 is visible in the figure. The base 150 of the second shield plate 105 abuts against the rear connector housing wall 111 of the connector housing 110. In this embodiment, the housing wall 111 is formed straight and has two substantially parallel inner and outer faces defining therebetween a thickness d of the housing wall 111 or connector housing 110. A number of recesses 113 are disposed on an upper outer edge 112 of the connector housing wall 111 surrounding the plug opening. The number and positions of the recesses 113 correspond to the number and positions of the spring contact elements 151.

[0036] The following description is based on an exemplary spring contact element 151 of the second shield plate 105 and a corresponding recess 113 in the connector housing 110 .

[0037] As already explained above, each recess 113 comprises two webs 114a, 114b (only one of which is visible in the cross-section in Figs. 5 and 6) arranged laterally of the recess 113. Between the two webs 114a, 114b, a gap is formed. The main part of the T-shaped fastening element 153 connected to the bent part 152 is guided from the inside through this gap into the recess 113 and then branches from there into two parts bent at an angle of 90°. These bent parts are formed to be arranged opposite each other in opposite directions, are flush with the main part and extend into the recess 113. Here, the T-shaped fastening element 153 does not protrude beyond the outer edge 112 of the connector housing 110.

[0038] In the non-inserted state shown in Fig. 5, the T-shaped fastening element 153 is pressed against the webs 114a, 114b due to the pretension of the spring contact element 151. The right bend rests with its inner side against the outer side of the right web 114a, and the left bend rests with its inner side against the outer side of the left web 114b (the latter is only visible in Fig. 4 and not in Figs. 5 and 6). This realizes a first fastening of the shield plate 150, which prevents the spring contact element 151 from tilting inwards.

[0039] Since neither the curved portion 152 nor the fastening element 153 are guided above the webs 114a, 114b, the height of the webs 114a, 114b can be chosen virtually arbitrarily, with the constraint that the webs 114a, 114b are high enough to hold the fastening element 153 against the pretension of the spring element 151 in the recess 113, even if the fastening element 153 does not rest on the bottom of the recess 113, as shown in Figure 5. In the non-inserted state, the fastening element 153 is held at a height such that it can pivot downwards when flexed during the insertion process.

[0040] In the plugged-in state shown in FIG. 6, the spring contact element 151 of the second shield plate 105 is deflected by the mating connector (not shown) and abuts against the inner side of the connector housing wall 111. In this embodiment, the spring contact element 151 has a curved portion 152 that abuts against the inner side of the connector housing wall 111 at least at point P. The T-shaped fastening element 153 moves outward in the recess 113 and pivots downward in the process. The T-shaped fastening element 153 and the curved portion 152 are configured such that the distance perpendicular to the surface of the housing wall 111 between the outer side of the T-shaped fastening element 153 and point P corresponds to the thickness d of the housing wall 111. Even when the spring contact element 151 abuts against the connector housing 110, the fastening element 153 remains in the recess 113 and does not protrude from the connector housing 110. The distance a minus the thickness of the web 114a or 114b and the width of the bent portion of the T-shaped fastening hook 153 corresponds to the maximum deflection of the spring contact element 151 in the direction of the center of the connector.

[0041] To achieve further fastening, the connector housing 110 comprises a number of supports 116 protruding vertically from the connector housing wall 111. The base 150 of the second shield plate 105 presses downwards against the supports 116. In addition, the second shield plate 105 comprises a number of soldering pads 154 arranged on the lower surface of the base 150. The soldering pads 154 extend laterally beyond and surround the supports 116. The soldering pads 154 are each soldered to a third soldering point 22 of the circuit board 2. This firstly achieves an electrical contact between the second shield plate 105 and the circuit board 2, and secondly achieves fastening of the second shield plate 105 to the circuit board 2 and the connector housing 110. Additionally, the second shield plate 105 includes elongated portions 155 between the solder pads 54 that engage openings 117 in the support portion 116. The elongated portions 155 may include fastening elements (not shown) that engage complementary fastening elements in the openings 117. This forms an additional fastening of the second shield plate 105 to the connector housing 110.

[0042] The support 116 may be used in the first embodiment in addition to or instead of the fastening shoulder to achieve further fastening. In the second embodiment, as well as in the third and fourth embodiments described below, the fastening shoulder according to the first embodiment may be used as further fastening.

[0043] 7a and 7b show a third embodiment of a connector 101 according to the invention, with 7b showing a detailed view of section VII of 7a. 8a and 8b show a fourth embodiment of a connector 102 according to the invention, with 8b showing a detailed view of section VII of 8a. The third and fourth embodiments differ from the second embodiment in that the fastening elements are configured as L-shaped fastening elements 153a, 153b. Each of the L-shaped fastening elements 153a, 153b comprises a bent part at an angle of 90°. The bent part is flush with the main part and extends in one direction into the recess 113. Here, the L-shaped fastening elements 153a, 153b do not protrude beyond the outer edge 112.

[0044] The right-bent fastening element is designated here by 153a, the left-bent fastening element by 153b. The bending direction of the L-shaped fastening elements 153a, 153b can be virtually freely selected. A preferred configuration, in which the first fastening of the shield plate 105 is achieved and in which the spring contact elements 151 are prevented from tilting inwards, will be described below.

[0045] In the third embodiment in Fig. 7a and 7b, the L-shaped fastening elements 153a are bent in the same direction, i.e. to the right in this example, but it is also possible for the fastening elements to be bent only to the left. All L-shaped fastening elements 153a are therefore configured identically, which simplifies serial production. In this embodiment, the recesses 113 of the connector housing 110 also each comprise two webs 114a, 114b. In other embodiments, it may be provided to provide a web 114a only on the side where the L-shaped fastening elements 153a are bent. In the non-inserted state, the L-shaped fastening elements 153a are pressed against the right web 114a due to the pretension of the spring contact element 151, and the bent part abuts with its inner side against the outer side of the right web 114a.

[0046] In the fourth embodiment in Fig. 8a and Fig. 8b, adjacent L-shaped fastening elements 153a, 153b are alternately bent such that the L-shaped fastening element 153a bent to the right is arranged next to the L-shaped fastening element 153b bent to the left. In this embodiment, the recesses 113 of the connector housing 110 further comprise two webs 114a, 114b respectively. In other embodiments, it may be provided to provide a web 114a or 114b per recess 113 only on the side where the L-shaped fastening element 153a or 153b is bent. In the non-inserted state, the L-shaped fastening element 153a bent to the right is pressed against the right web 151 due to the pretension of the spring contact element 151, and the bent part abuts with its inner side against the outer side of the right web 114a.

[0047] Likewise, the L-shaped fastening element 153b bent to the left is pressed against the left web 114b due to the pretension of the spring contact element 151, with the bent part abutting with its inside against the outside of the left web 114b. This alternating arrangement ensures a stable hold, in particular against unscrewing.

[0048] In the above embodiments, straight connectors 1, 100, 101, 102 are shown. The above features may also be adopted in bent connectors.
