Description

  An electrical connector assembly generally includes circuits and components on one or more circuit boards that are connected together by an electrical connector.

Examples of electrical components in the electrical connector assembly can include a daughter board, a motherboard, a backplane board, a midplane board, or the like. The electrical connector provides an interface between electrical components and further provides electrical communication paths for telecommunications data signals and / or power.

  Referring to FIG. 1, for example, an example conventional electrical assembly 20 includes a card edge connector 22 that connects between a first circuit board 24 and a second circuit board 26. The card edge connector 22 is a sort mount style card edge connector having an electrical conduction path between the edge trace of the first printed wiring circuit board 24 and the edge trace of the second printed wiring circuit board 26. Illustrated and illustrated to be a coplanar with a first printed circuit board 24. Such a configuration can be suitable for an electrical assembly in an enclosure such as a 1U rack mount server. The card edge connector 22 has a connector housing 28 having a housing body 29 with a plurality of electrical contacts 30, which can have electrical signal contacts 32 and power contacts 34.

  The card edge connector 22 defines a mounting interface 38 that receives the edge of the first printed circuit board 24 and a coupling interface 36 that receives the second printed circuit board 26. The first printed circuit board 24 includes a plurality of electrical contact pads 40 connected to the electrical contacts 30 of the card edge connector 22 when the first printed circuit board 24 is coupled to the card edge connector 22. Have Thereafter, the electrical contacts 30 and electrical contact pads 40 are typically soldered to establish a permanent electrical connection between the electrical contacts 30 of the card edge connector 22 and the first printed circuit board 24. .

  The second printed wiring circuit board 26 is inserted into the interface 38 to which the edge card connector 22 is coupled so that the electrical contact pads 42 of the second printed wiring circuit board 26 are in contact with the electrical contacts 30. Thereby establishing an electrical connection between the traces of the first printed circuit board 24 and the electrical contacts 30 of the card edge connector. It should be understood that the card edge connector 22 can be electrically connected to the first and second circuit boards 24 and 26 such that the first and second circuit boards 26 are arranged in telecommunications. . The second printed circuit board 26 can be removed from the mating interface 38 of the card edge connector 22 and reinserted into the mating interface 38, or other circuit boards are preferably in the mating interface 38. Can be inserted into. In this respect, the first printed wiring circuit board 24 can be referred to as a host board, and the second printed wiring circuit board 26 can be used for detachable electrical communication with the host board.

  The card edge connector 22 extends outward from the opposite side of the housing body 29 and further aligns with a corresponding opening on the first printed circuit board 24 when the electrical contact 30 is placed against the electrical contact 40. And has a pair of mounting ears 44 that provide openings to be placed. The aligned openings receive hardware 46 such as screws, nuts, and the like to provide a secure physical connection between the card edge connector 22 and the first printed circuit board 24. Configured as follows. Therefore, the stress applied to the card edge connector 22 from the second printed wiring circuit board absorbed by the connection between the electrical contact 30 and the electrical contact pad 40 is caused by the second printed wiring circuit board 26. When coupled to the card edge connector 22, it is at least partially absorbed into a secure physical connection between the card edge connector 22 and the first printed circuit board 24.

  Unfortunately, the mounting ears 44 occupy a valuable area on the first printed circuit board 24.

  According to one embodiment, the card edge connector is configured to mount on a first printed circuit board along the direction of insertion. The card edge connector has a connector housing having a housing body. The housing body defines first and second side walls. The connector housing is associated with a plurality of electrical contacts arranged between the first and second side walls.

  With reference to FIGS. 2A-B, the electrical connector assembly 50 includes a first printed wiring circuit board 52 for telecommunications with a second printed wiring circuit board 54, respectively. A first substrate, such as a printed circuit board (PCB) 52, a second substrate, such as a second printed circuit board (PCB) 54, and first and second substrates 52 and 54. Electrical connector 56 configured to be electrically connected between the two. The electrical connector 56 is illustrated as a card edge connector and can be configured as a mount connector that straddles according to one embodiment as described in more detail below.

  The electrical connector 56 has a dielectric, which can be made of any suitable dielectric material having a plastic such as high temperature thermoplastic, or an electrically insulative connector housing 58. The connector housing 58 includes a housing body 59 with one or more electrical contacts 60 configured to engage complementary electrical traces on the first and second circuit boards 52 and 54. Each has. In particular, the connector housing 58 defines a mounting interface 62 and a mating interface 64 separated along the longitudinal direction L. The mounting interface 62 is configured to be electrically and physically connected to the first printed wiring circuit board 52, and the coupling interface 64 is electrically and physically connected to the second printed wiring circuit. It is configured to be connected to the circuit board 54. The electrical contact 60 is an interface 64 that couples with the mounting interface 62 to electrically connect to the first printed wiring circuit board 52 when the electrical connector 56 is mounted to the first printed wiring circuit board 52. And when the electrical connector 56 is coupled to the second printed circuit board 54, it is connected to the second printed circuit board 54. According to one embodiment, the mounting interface 62 allows the electrical contacts 60 to straddle the first printed wiring circuit board 52 when the electrical connector 56 is mounted on the first printed wiring circuit board 52. It can be configured as a mount interface. Accordingly, the connector housing 58 can be referred to as a mount card edge housing that straddles according to the illustrated embodiment. The electrical connector 56 can be called a card edge connector, and in particular, can be called a straddling mount connector.

  Referring now to FIGS. 3-4, the housing body 59 defines a front edge 66 and a rear edge 68 that are spaced from the front edge 66 along the longitudinal direction L. The front edge 66 is disposed proximate to the interface 64 to be coupled, and the rear edge 68 is disposed proximate to the mounting interface 62. The housing body 59 further includes a first side wall 70 separated from the first side wall 70 along the lateral direction extending in the lateral direction A substantially perpendicular to the longitudinal direction L, and an opposing second side wall 71. Is defined. First and second side walls 70 and 71 extend between mating interface 64 and mounting interface 62. The housing body 59 is elongated along the lateral direction A, and the individual electrical contacts 60 are spaced along the lateral direction A. The housing body 59 further defines an upper edge 72 and opposing lower edges 74 spaced from the upper edge 72 along a transverse direction T that is substantially perpendicular to both the longitudinal direction L and the transverse direction A. It should be appreciated that the longitudinal and lateral L and A respectively extend horizontally and that the orientation of the electrical connector 56 may change during operation, but the longitudinal T is illustrated. So as to extend vertically.

  As illustrated in FIGS. 2A-B, when mounted on the first printed wiring circuit board 52 of the electrical connector 55, the top surface 96 of the pair of opposing side surfaces 51 and 53 and the opposing bottom surface 98. One printed circuit board 52 defines a leading edge 90 with respect to the direction of insertion 87. When the electrical connector 56 is mounted on the first printed circuit board 52, the top surface 96 is spaced from the bottom top surface 98 along the transverse direction T. Further, the side sides 51 and 53 are arranged along the lateral direction A with a gap. The top and bottom surfaces 96 and 98 can be substantially, for example planar, along a plane defined by the longitudinal and lateral directions. Thus, when coupled to electrical connector 56, top and bottom surfaces 96 and 98 can extend along both lateral direction A and longitudinal direction L. The second printed circuit board 54 similarly defines a leading edge 91 with respect to the direction of insertion so as to couple with the electrical connector 56.

  As further illustrated in FIG. 5, the connector housing 58 has a chamber 76 defined by a housing body 59. Electrical contact 60 is accompanied by housing 58 such that electrical contact 60 is at least partially disposed within chamber 76. The chamber 76 can be open to the mating interface 64 and receives the second printed wiring circuit board 54 to couple the electrical connector 56 to the second printed wiring circuit board 54. It can be constituted as follows. Chamber 76 can be opened or closed with respect to mounting interface 62. For example, the housing body 59 can have a rear wall 78 that partially closes the chamber 76 at the mounting interface 62. The housing body 59 can define a plurality of apertures 80 that extend through the rear wall 78 such that the electrical contacts 60 extend through each of the apertures 80.

  The electrical contact 60 can desirably be made of any suitable electrically conductive material, such as a copper alloy. The electrical contact 60 is sized and configured to transmit electrical communication or data signals between the first and second substrates 52 and 54, and further includes first and second electrical signal contacts 61. Between the substrates 52 and 54, there can be a plurality of power contacts 63 dimensioned and configured for transmission power, such as DC and / or AC AC power supplies. Thus, the power contact 63 is larger than the electrical signal contact 61 and can be dimensioned to support a DC and / or AC power source. For example, the power contact 63 can have a greater thickness (eg, in one direction or both in the horizontal and vertical directions) than the electrical signal contact 61. In accordance with the illustrated embodiment, electrical contacts 60 can be arranged such that electrical signal contacts 61 are disposed laterally adjacent to power contacts 63. For example, the electrical signal contact 61 can be located proximate to one of the side walls of the housing body 59, such as the first side wall 70 as illustrated. The individual electrical signal contacts 61 are spaced laterally such that the electrical signal contacts 61 are arranged laterally inwardly from the first side wall 70 toward the second side wall 71. Can do. The power contact 63 can be disposed adjacent to the opposing one of the side walls with respect to the side wall adjacent to the electrical signal contact 61. In accordance with the illustrated embodiment, the power contact 63 is disposed adjacent to the second side wall 71. Individual ones of the power contacts 63 can be spaced laterally such that the power contacts 63 are arranged laterally inwardly from the second side wall 71 toward the first side wall 70. [0033] Alternatively, as illustrated in FIGS. 11A-D, electrical connector 56 is constructed such that electrical contacts 60 lack electrical signal contacts and thus have only power contacts 63. Can do. This power contact can be arranged between the first and second side walls 70 and 71. Thus, reference herein to this electrical contact 60 refers to both the electrical signal contact 61 and the power contact as illustrated in FIGS. 1-9, or just the power contact 63 as illustrated in FIGS. 11A-D. That you can have.

  2A-4 and 7-8, the connector housing 58 has first and second openings 65 and 67 extending laterally through the upper and lower ends 74 and 72 of the housing body 59. It can have at least one outer row of openings, such as a transverse row. The first row of apertures 65 can be located proximate to the interface 64 to be coupled, and the second row of apertures 67 can be located proximate to the mounting interface 62.

The first row of openings 65 can be aligned with the power contacts 63 to facilitate heat dissipation from the connector housing 58. Heat is generated as power is transmitted along the power contacts 63 during operation of the electrical connector assembly 50.

An electrical connector 58 extends into each of the second row of openings 67 to latch the power contacts 63 and to configure the tabs 69 to assist in securing the power contacts 63 within the connector housing 58. Have

  Each of the electrical contacts 60 having electrical signal contacts 61 and power contacts 63 can define a respective mounting end 82 and opposing mating ends 84 that are longitudinally spaced from the mounting end 82. The mounting end 82 is effective to electrically connect to the contact pads 86 of the first printed wiring circuit board 52 when the electrical connector 56 is mounted on the first printed wiring circuit board 52. In cooperation with the mounting interface 62. The connecting end portion 84 is electrically connected to the conductor pad 88 of the second printed wiring circuit board 54 when the electrical connector 56 is mounted on the second printed wiring circuit board 54. It cooperates with an interface 62 that effectively couples. Therefore, when the electrical connector 56 is attached to the first and second circuit boards 52 and 54, respectively, an electrically conductive path is formed from the electrical contact pad 86 on the first printed circuit board 52. It can be established via the respective electrical contacts 60 and further between the respective electrical contact pads 88 of the second printed circuit board 54. First and second circuit boards 52 and 54 are further accompanied by electrical traces that are electrically connected to respective electrical contact pads 86 and 88.

  Electrical contact pads 86 are disposed. The first printed wiring circuit board 52 is disposed close to the leading edge 90, and the electrical contact pad 88 is disposed close to the second printed wiring circuit board 54 leading edge 91. When the electrical connector 22 is mounted on the first printed wiring circuit board 52, the side wall 70 of the housing body 59 extends in a substantially vertical direction with respect to the leading edge 90 of the first printed wiring circuit board 52. As illustrated. Similarly, when the electrical connector 22 is coupled to the second printed wiring circuit board 54, the side wall 70 of the housing body 59 is in a direction substantially perpendicular to the leading edge 91 of the second printed wiring circuit board 54. Illustrated to extend.

  The connecting end 84 of the electrical contact 60 having its electrical signal contact 61 and electrical power contact 63 can be accompanied, for example, in the housing body 59 of the chamber 76, and the second printed circuit board 54 is When inserted into the chamber 76 of the interface 64 that couples the electrical connector 56 and the second printed wiring circuit board 54 together, it spans the leading edge of the second printed wiring board 54. Each configured can have laterally opposed prongs. The mounting end 82 of the electrical contact 60 having the electrical signal contact 61 and the power contact 63 can extend through the rear wall 78 of the housing body 59.

As illustrated in FIG. 4, each mounting end 82 can have opposing protrusions 94 that each define a gap 95 therebetween, and the electrical connector 56 is connected to the first printed circuit board 52. A pleated end that can provide guidance when mounted on can be represented.

The opposing protrusions 94 are configured to straddle the first printed wiring circuit board when the electrical connector 56 is mounted on the first printed wiring circuit board, such as the upper and lower rows, It can be arranged in first and second columns.

  As illustrated in FIG. 2B, when the electrical connector 56 is attached to the first printed circuit board 52, the opposing protrusion 94 straddles the leading edge 90 of the circuit board 52, which is within the gap 95. Inserted into.

The contact pads 86 are disposed on the top surface 96 and / or the lowermost surface 98 of the first printed circuit board 52 and can be dimensioned to electrically connect to individual ones of the electrical contacts 60. Can be dimensioned to connect electrically to two or more of the electrical contacts 60. For example, according to the illustrated embodiment, up to all of one or more conductor pads 86 can be dimensioned for electrical connection to individual ones of electrical signal contacts 61. Further, it should be appreciated that according to the illustrated embodiment, one or more of all conductor pads 86 can be dimensioned electrically to connect to individual ones of power contacts 63. However, one or more can be dimensioned to all of the conductor pads 86 for electrical connection to two or more of the power contacts 63. Therefore, when the electrical connector 56 is attached to the first printed wiring circuit board 52, the mount end 82 of the electrical contact 60 is connected to the top surface 96 of the first printed wiring circuit board 52. And the lowermost surface 98 can be sandwiched, and further, electrically conductive paths are established from the electrical contacts 60 to the respective electrical traces that are energized by the contact pads 86 and the first printed circuit board 52. be able to.

  The electrical connector 56 includes a connector 56 and a circuit board along a vertical insertion direction such that the mounting interface 62 of the electrical connector 56 receives the leading edge 90 of the circuit board 52 until the electrical contact 60 engages the conductor pad 86. By providing a relative vertical movement on at least one of 52, it can be attached to the first printed circuit board 52. Thereafter, the electrical contacts 60 can be soldered to the contact pads 86 as desired to permanently secure the first printed circuit board 52 to the electrical connector 56. In this respect, the first printed circuit board 52 can be called a host board.

  As illustrated in FIGS. 4 and 6, the connector housing 58 extends laterally between the upper edge 72 and the lower edge 74 at a mounting end 62 in a lateral position between the signal contact 61 and the power contact 63. The polarization member can be in the form of a polarization wall 101 extending in the direction. The polarization wall 101 is thus arranged with a position offset with respect to the central position in the lateral direction of the housing body 59. The first printed circuit board 52 may define a slot 109 (see FIG. 2B) that extends longitudinally inward from the leading edge 90 and is dimensioned to receive the polarizing wall 101, thereby Ensuring that the first printed circuit board 52 is properly oriented for connection to the electrical connector 56. In particular, when the electrical connector 56 is mounted on the first printed circuit board 52, the electrical pad 86 configured to engage the signal contact 61 engages the signal contact 61 and When the connector 56 is mounted on the first printed circuit board 52, the electrical pad 86 configured to actually engage the power contact 63 engages the power contact 63.

  Further, the polarization wall 101 can be illustrated as opposing upper and lower portions, and can have opposing outer portions 103 and an intermediate portion 105 disposed between the opposing outer portions 103.

The opposing outer portions 103 can have a greater lateral thickness than the intermediate portion 105. For example, the lateral thickness of the opposing outer portions 103 can extend into the leading edge 90 and be greater than that of the slot 109. The lateral thickness of the intermediate portion 105 is dimensioned to be approximately equal to or less than that of the slot 109 such that the intermediate portion 105 is configured to be received within the slot 109. The middle portion 105 is first so that the first printed circuit board 52 can be substantially supplemented between the upper and lower portions 103 to facilitate engagement of the contact pads 86 and the electrical contacts 60. A transverse dimension or height equal to that of the printed circuit board 52 can be defined.

  The intermediate portion 105 is aligned with the gap 95 between the protrusions 94 on the mounting end 82 of the electrical contact 60. Accordingly, the intermediate portion 105 of the polarization wall 101 is aligned to properly align the first printed wiring circuit board 52 with the electrical contacts 60 when the electrical connector 56 is mounted on the first printed wiring circuit board 52. Provide a guide. In this regard, it should be appreciated that the first printed wiring circuit board 52 has complementary polarizing members and alignment guides configured to engage the polarizing members and alignment guides of the electrical connector 56. is there. In accordance with the illustrated embodiment, the polarizing member and alignment guide of the first printed circuit board 52 are provided by a slot 109 that extends vertically into the leading edge 90. However, the polarization members and alignment guides of both the electrical connector 56 and the first printed circuit board 52 are alternatively, as two separate members that are spaced apart from each other if desired. Can be provided.

  Referring again to FIGS. 2B and 3, an edge card such as the second printed circuit board 54 can be removed before or after the electrical connector 56 is mounted on the first printed circuit board 52. The electrical connector 56 can be coupled. In particular, the electrical connector 56 has an interface 64 to which the electrical connector 56 is coupled until the electrical contact 60 engages the contact pad 88 so that the leading edge 91 of the second printed circuit board 54 along the vertical insertion direction. By receiving a relative vertical movement in at least one of the electrical connector 56 and the second circuit board 54, it can be attached to the second printed circuit board 54.

  The connector housing 58 is in the form of a polarizing wall 115 extending laterally between the upper edge 72 and the lower edge 74 at a lateral position between the signal contact 61 and the power contact 63 at the joining end 64. It can have two polarization members. The polarization wall 115 is thus arranged at a position offset with respect to the lateral center position of the housing main body 59. The second printed wiring circuit board 54 can define a slot 111 extending inwardly from the leading edge 91 and dimensioned to receive the polarization wall 115, thereby enabling the second printed wiring circuit. Ensure that the board 54 is properly oriented for connection to the electrical connector 56. In particular, when the electrical connector 56 is coupled to the second printed circuit board 54, the selected one of the electrical pads 88 can engage the signal contact 61, and further the selected one of the electrical pads 88. Can engage with the power contact 63.

  It should be recognized. When the second printed circuit board 54 is coupled to the electrical connector 56, the angle or directivity between the leading edge 91 of the second printed circuit board 54 and the chamber 76 of the housing body 59 is poor. When alignment may be applied to stress the electrical contact 60, it in turn stresses the solder connection between the electrical contact 60 and the electrical pad 86 of the first printed circuit board 52. It is something to add. For example, when the second printed wiring circuit board 54 is inserted into the chamber 76 and the second printed wiring circuit board 54 is misaligned with the connector housing 58, the insertion force is applied to the electrical contacts 60, Therefore, it can be converted into a solder connection for attaching the electrical contact 60 to the contact pad 86 of the first printed circuit board 52.

  Thus, as described above, the conventional straddling mount connector has a connector housing 58 (FIG. 1) that prevents the coupling force from biasing the electrical connector 22 in movement relative to the first printed circuit board 24. A pair of mounting ears 44 for securing the first printed wiring circuit board 24 to the first printed wiring circuit board 24, which is a solder between the electrical contacts 32 and the contact pads of the first printed wiring circuit board 52. May completely affect the connection.

However, the mounting ear 44 occupies a valuable area on the first printed circuit board 24.

  Still referring to FIGS. 2A-4 and 6, the connector housing 58 can lack a mounting ear of the type described above with respect to FIG. 1, and the electrical connector 56 can be a second printed wiring circuit. Can be configured to limit the stress experienced by the electrical contacts 60 when the second printed wiring circuit board 54 is accidentally adjusted in the housing body 59, for example. Is recognized. Accordingly, the first printed circuit board 52 may lack an opening configured to receive a fastener to secure the first printed circuit board 52 to the electrical connector 56. Should be recognized. According to one embodiment, since the electrical signal contact 61 is thinner than the power contact 63, the coupling stress of the conventional straddling mount connector is further increased between the electrical contact 63 of the first printed circuit board 52 and the electrical contact. Compared to the solder connection between contacts 86, it is likely to affect the integrity of the solder connection between electrical signal contacts 61. The electrical connector 56 may be missing the mounting ears and at the same time limit the poor alignment stress within the acceptable level, which is the electrical contact 60 of the first printed circuit board 52 that fails. And a level at which solder connection between the electrical contacts 86 is not caused.

  In accordance with the illustrated embodiment, the connector housing 58 of the electrical connector 56 lacks mounting ears, and instead, when the electrical connector 56 is mounted to the first printed circuit board 52, the first It has at least one mounting guide such as a pair of mounting guides 110 that slidably engage one printed circuit board 52. Mounting guide 110 may be accompanied by at least one side wall of connector body 59, such as first and second side walls 70 and 71, respectively. The first and second mounting guides 110 can be defined by opposing channels 112 and 113 that are accompanied by side walls 70 and 71 corresponding to the first and second lateral directions, respectively. For example, the first and second side walls 70 and 71 each define an inner surface 114 that faces each other laterally and an outer surface 116 that faces away from the respective inner surface 114 in the lateral direction. According to one embodiment, one or both first and second channels 112 and 113 are defined by respective side walls 70 and 71 and extend laterally out into inner surfaces 114 and 116. Can do.

  Thus, now referring to FIGS. 2A-B and 10A-D, each of the side walls 70 and 71 includes a first or upper inner surface 120 and a laterally opposed second or upper inner surface 120. A lower inner surface 122 can be defined that is laterally spaced from. The top and bottom inner surfaces 120 and 122 can define the lateral top and bottom boundaries of the respective first and second channels 112 and 113. Each of the side walls 70 and 71 can further define a third or lateral surface 124 connected between the upper and lower surfaces 120 and 122. The lateral surface 124 can define a first lateral end, such as a lateral outer end, of each first and first channel 112 and 113. The first and second channels 112 and 113 further have a second opposing lateral inner end 126 or mouth that is open to receive the first printed circuit board 52. It is configured. As illustrated, the upper and lower surfaces 120 and 122 can be substantially parallel to each other or can be offset at an angle with respect to each other. Further, the lateral sides 124 can be perpendicular to the upper and lower surfaces 120 and 122 or can define any angle with respect to the upper and lower inner surfaces 120 and 122 as desired.

The upper inner surface 120 is spaced from the upper end 72 of the housing body 59, and the lower inner surface 122 is spaced from the lower inner surface 72 of the housing body 59, for example, spaced from the upper inner surface 120. Arranged at a distance from the upper end 72 of the housing body 59 at a distance approximately equal to the distance at which it is disposed. Thus, each of the channels 112 and 113 can be substantially symmetrically spaced with respect to the upper and lower ends 72 and 74 of the housing body 59.

  Each of the first and second side walls 70 and 71 is thus a first lateral exterior, or upper portion 126, and a respective lateral interior surface that provides an upper interior surface 120. And a second lateral exterior, or lower portion 128, each lateral interior surface providing an upper interior surface 122 and further laterally A third laterally outer portion 130 that defines the outer surface 124 is shown. The first laterally outer portion 126, the second laterally outer portion 128, and the third laterally outer portion 130 can be integrated with each other so that the channels 112 and 113 are It can be separate or attached so as to penetrate into the respective first and second side walls or to define channels 112 and 113 with respect to each other.

Channels 112 and 113 are laterally aligned with each other and with a gap 95 between the protrusions 94 of the electrical contacts. Thus, a straight line extending through the gap 95, such as a laterally extending line, can further extend into the channels 112 and 113. In addition, straight lines extending into channels 112 and 113, such as laterally extending lines, may be connected to at least one of the electrical contacts 60, eg, all of the protrusions 94, in one or both of the first and second rows of electrical contacts. Can cross. For example, according to one embodiment, each of the upper and lower rows of electrical contacts 60 intersects a plane defined by respective upper and lower surfaces 120 and 122 that define at least the channels 112 and 113. It extends along the transverse direction. Otherwise, the straight line extending from the inner surface 120 on the top of one of the channels 112 and 113 to the inner surface 120 on the other top of the channels 112 and 113 is the first row of electrical contacts 60. The contacts 60 can intersect with at least one to all. Similarly, the straight line extending from the lower inner surface 122 of one of the channels 112 and 113 to the lower inner surface 122 of the other of the channels 112 and 113 is all of the electrical contacts 60 in the second row of electrical contacts 60. Until at least some intersection. Further, the first and second channels 112 and 113 can be aligned with the mid-section 105 or the alignment guide of the electrical connector 56, which means that the first printed circuit board 52 is connected to the channels 112 and 113. 113, so that it should be inserted into the gap 95 of the electrical contact 60 with the leading edge 90 of the first printed circuit board 52. Channels 112 and 113 each have a further outer end 132 in the longitudinal direction that provides a leading end with respect to the direction of insertion 87 when mounting the electrical connector 56 on the first printed circuit board 52 in the longitudinal direction. Can have. Channels 112 and 113 each further have a longitudinal inner end 134 opposite the longitudinal direction of outer end 132 and further provide a termination with respect to direction 87 of insertion. The outer end 132 can be open, and when the electrical connector 56 is mounted on the first printed circuit board 52 and the channels 112 and 113 receive the first printed circuit board 52. , Configured to receive the first printed wiring circuit board 52 at the leading edge 90, for example, such that the channels 112 and 113 capture the opposing side surfaces 51 and 53 of the first printed wiring circuit board 52. . The outer end 132 can be inclined so that the leading edge 90 is narrowed while being inserted into the channels 112 and 113. The inner end 134 may define a stop surface configured to abut its leading edge 90 so as to limit the insertion depth of the first printed circuit board 52 in the electrical connector 56.

Accordingly, each of the channels 112 and 113 define a longitudinal insertion depth parallel to the insertion direction 87 between the first or longitudinal outer end 132 and the longitudinal inner end 134, respectively. Can do. The rear end 68 of the housing body 59 further provides a stop that limits the insertion depth of the first printed wiring circuit board into the electrical connector 56 so that the leading edge 90 of the first printed wiring circuit board. Can abut. Further, each of the channels 112 and 113 has a laterally outer insertion depth D as measured laterally from the second or respective laterally inner end 126 to the respective laterally outer surface 124. Define. Each of the channels 112 and 113 further defines a lateral depth D1 as measured laterally between the third or upper inner surface 120 and the lower inner surface 122.

The lateral depth D1 can be greater than the first thickness T1 of the gap 95.

Further, the first and second rows of mounting ends 82 of the electrical contacts 60 that define the lateral thickness T1 can be offset inwardly with respect to the upper and lower inner surfaces 120 and 122.

  During operation, when the electrical connector 56 is mounted on the first printed circuit board 52, at least a first channel, such as the first and second channels 112 and 113, is the first and second channels. Each side receives at least one side of the printed circuit board 52, such as the side 51, and is longitudinally within the channels 112 and 113 at such a first printed circuit board 52, eg, the sides 51 and 53. Extends in the longitudinal direction by an amount approximately equal to the insertion depth in the direction. The first printed circuit board 52 is received, for example, completely in the channels 112 and 113 until the leading edge 90 abuts the inner end 134 and / or the rear end 68 of the housing body 59. Further, at least one channel such as channels 112 and 113 receives at least one side surface of the first printed circuit board 52, such as the first and second sides 51 and 53, for example, the first The printed circuit board 52 extends in the lateral direction by an amount substantially equal to the lateral insertion depth D in the laterally outer side in the channels 112 and 113 on the sides 51 and 53. For example, the electrical connectors 56 are mounted on the first printed circuit board at the respective mounting ends 82, and the protrusions 94 of the electrical contacts 60 straddle the first printed circuit board 52. Each row is in contact with an electrical contact pad 86 on the upper surface 96 of the first printed circuit board, and each second row of electrical contacts 60 is a lower portion of the first printed circuit board 52. It is intended to come into contact with the electrical pad 86 on the part surface 98. The first thickness T1 of the gap 95 is less than the second thickness T2 of the first printed circuit board 52 before the first printed circuit board 52 is inserted into the gap 95, or , Almost equal (but not bigger). Thus, the leading edge 90 is received in the gap 95 and the first printed circuit board 52 can cause the mounting ends 82 to move away from each other.

  It will therefore be appreciated that the housing body 59 defines a first laterally outer dimension, or width W1, as defined between the laterally outer surfaces 124 of the first and second side walls 70 and 71. Should be. Further, the first printed wiring circuit board 52 defines the next lateral dimension between the sides 51 and 53, or the width W2. It is such that the first width W1 is approximately equal (eg, equal to or slightly larger) than the second width W2. Further, the first printed circuit board 52 is illustrated as a second thickness T2 to define a thickness, which can be a lateral thickness between the upper and lower surfaces 96 and 98. The third lateral depth D3 is such that it is approximately equal to (eg, equal to or slightly larger than) the second thickness T2. Thus, the first and second side walls 70 and 71 are configured to capture the sides 51 and 53 of the first printed circuit board 52 of the channels 112 and 113, which are respectively the first and second The second side walls 70 and 71 are the first and second side walls 70 and 71 on the receiving side of the printed circuit board and the respective sides 51 and 53 of the first printed circuit board 52. At least a portion of the misalignment force that is in general coordination (eg, in direct contact) and that can be generated when the electrical connector 56 is coupled to the second circuit board 54 is transmitted from the connector housing 58. For example, at least a portion of the lateral misalignment force can be transmitted from the first lateral exterior or top surface 120 to the top surface 96 of the first printed circuit board 52 and And / or to the second lateral exterior, or to the lower surface 98 of the first printed circuit board 52 at a location spaced from the electrical contact pad 86 from the lower portion 122. be able to. At least the laterally-aligned defective alignment force can be transmitted from at least one or both of the third laterally outer surfaces 124 of the respective sides 51 or 53 of the first printed circuit board 52. It should be appreciated that the poor alignment force transmitted from the respective side walls 70 and 71 to the first printed circuit board 52 avoids a connection between the electrical contact 60 and the electrical contact pad 86. That is.

  The outer side 124 and inner end 134 and / or the rear end 68 of the housing body 59 are such that the electrical contact pads 86 are fully received in the channels 112 and 113 by the first printed circuit board 52. , And can be positioned to become physically and electrically connected to the electrical contact 60. Further, since the first width W1 of the housing main body 59 is substantially equal to the width W2 of the first printed wiring circuit board 52, the lateral depth D1 of the channels 112 and 113 is further set to the first printed wiring circuit board 52. Therefore, the first printed circuit board 52 is captured by at least one channel, such as the channels 112 and 113. It is because at least a part of the force applied to the connector 56 due to the bad alignment between the second printed circuit board 54 and the electrical connector 56 causes the electrical connector 56 to be applied to the second printed circuit board 54. When coupled, this time is applied to the received first printed circuit board 52, thereby a portion of the force from the connection between the electrical contact 60 and the first printed circuit board 52. So as to separate. The electrical connector 56 can be mounted on the first printed wiring circuit board 52 without the use of a mechanical fastener extending by the first printed wiring circuit board 52. Accordingly, the mechanical fasteners that are extended by the first printed circuit board 52 may be lacking so that the electrical connector assembly 50 mounts 56 to the electrical connector first printed circuit board 52. That may be said.

When the electrical connector 56 is mounted on the first printed circuit board 52, the top surface 96 is spaced from the bottom top surface 98 along the transverse direction T. Further, the side sides 51 and 53 are arranged along the lateral direction A with a gap. The top and bottom surfaces 96 and 98 can be substantially, for example planar, along a plane defined by the longitudinal and lateral directions. Thus, when coupled to electrical connector 56, top and bottom surfaces 96 and 98 can extend along both lateral direction A and longitudinal direction L.

For example, the housing body 59 can have a rear wall 78 that partially closes the chamber 76 at the mounting interface 62. The housing body 59 can define a plurality of apertures 80 that extend through the rear wall 78 such that the electrical contacts 60 extend through each of the apertures 80.

The electrical contact 60 can desirably be made of any suitable electrically conductive material, such as a copper alloy. The electrical contact 60 is sized and configured to transmit electrical communication or data signals between the first and second substrates 52 and 54, and further includes first and second electrical signal contacts 61. Between the substrates 52 and 54, there can be a plurality of power contacts 63 dimensioned and configured for transmission power, such as DC and / or AC AC power supplies.

For example, the power contact 63 can have a greater thickness (eg, in one direction or both in the horizontal and vertical directions) than the electrical signal contact 61. In accordance with the illustrated embodiment, electrical contacts 60 can be arranged such that electrical signal contacts 61 are disposed laterally adjacent to power contacts 63. For example, the electrical signal contact 61 can be located proximate to one of the side walls of the housing body 59, such as the first side wall 70 as illustrated. The individual electrical signal contacts 61 are spaced laterally such that the electrical signal contacts 61 are arranged laterally inwardly from the first side wall 70 toward the second side wall 71. Can do. The power contact 63 can be disposed adjacent to the opposing one of the side walls with respect to the side wall adjacent to the electrical signal contact 61.

Should be recognized. According to one embodiment, since the electrical signal contact 61 is thinner than the power contact 63, the coupling stress of the conventional straddling mount connector is further increased between the electrical contact 63 of the first printed circuit board 52 and the electrical contact. compared to solder connection between a contact pad 86, can affect the integrity of the solder connection between the electrical signal contacts 61 and electrical contact pads 86 of the first printed circuit board 52 That's right. Electrical connector 56 is obtained may mounting ear is missing, at the same time, an acceptable level, i.e. the solder connections between the electrical contacts 60 and electrical contact pads 86 of the first printed circuit board 52 The misalignment stress can be limited to a level that does not cause failure .

It extends along the transverse direction. Stated another way, the straight line extending from the upper inner surface 120 of one of the channels 112 and 113 to the upper inner surface 120 of the other of the channels 112 and 113 is the first row of electrical contacts of the electrical contacts 60. Up to 60, at least one can be crossed. Similarly, the straight line extending from the lower inner surface 122 of one of the channels 112 and 113 to the lower inner surface 122 of the other of the channels 112 and 113 is all of the electrical contacts 60 in the second row of electrical contacts 60.
