Description

Electric connector shell and base combination, electric connector and electronic device

Technical Field

The present invention relates to an electrical connector, and more particularly to an electrical connector with a heat dissipation structure.

Background

Electrical connectors have been widely used in the environment of power or signal connections, such as the connection of an electronic host device to an external device. As the electrical connector experiences a substantial increase in transmission speed, the heat generated also increases substantially. In this regard, the housing of the connector may be provided with heat dissipating fins to facilitate heat dissipation. In some applications, to indicate the operation status of the connector, the connector is provided with an indicator light implemented by a light guide guiding light emitted from a light source. The light guide is in principle placed against the connector housing, which causes structural interference between the light guide and the heat sink fins. In some structural configurations, the heat dissipation fins are disposed on the upper side of the connector housing, and the light guide member is also disposed on the upper side of the connector housing; the structure configuration has the advantage that the arrangement of the heat dissipation fins needs to be eliminated at the arrangement position of the light guide piece, so that the heat dissipation effect is inhibited. In some configurations, the heat dissipation fins are disposed on the upper side of the connector housing, and the light guide members are disposed on the left and right sides of the connector housing, so that the overall width of the connector is increased.

Detailed Description

Please refer to fig. 1 to 4. An electrical connector 1 according to an embodiment of the present invention includes a circuit board 12, two electrical connection sockets 14 and an electrical connector housing assembly 16. The electrical connector housing assembly 16 is secured to the circuit board 12. The two electrical connectors 14 are electrically connected to the circuit board 12 and located in the electrical connector housing assembly 16, which is represented by a solid block in the figure for simplicity. In practice, the two electrical connectors 14 can be structurally integrated into a single component for easy assembly. The electrical connector housing assembly 16 includes a connector housing 162, two heat dissipation structures 164, an elastic fastener 166 and two light guides 168. The heat dissipation structure 164 is disposed on the connector housing 162, and the elastic fastener 166 is connected to the connector housing 162 to elastically clamp the two heat dissipation structures 164 between the elastic fastener 166 and the connector housing 162. The two light-guiding members 168 are correspondingly disposed in the accommodating space formed by the two heat-dissipating structures 164 (as described later), and the light-guiding members 168 can guide light emitted from a light source (such as but not limited to a device housing and a plurality of light-emitting diodes disposed therein) on the circuit board 12, and can be used as an indication of the operation status of the electrical connector 1. The accommodating space is formed by a part of the heat dissipation structure 164 to accommodate the light guide member 168, so that the overall size of the electrical connector 1 is prevented from being too large, and the heat dissipation effect of the heat dissipation structure 164 is also prevented from being significantly affected by the arrangement of the light guide member 168.

In the present embodiment, the connector housing 162 has four outer sidewalls 162a-d and a partition 162e, and the outer sidewalls 162a-d are connected to form a receiving space 1620. The partition 162e is connected to the outer sidewalls 162a and 162c in the receiving space 1620 to divide the receiving space 1620 into two slots 1622, and the two electrical connectors 14 are respectively exposed to the two slots 1622. The socket 1622 has an entrance 1622a through which an external mating electrical connector may be inserted into the socket 1622 to engage the corresponding electrical connector socket 14. The heat dissipation structure 164 is disposed on the outer sidewall 162 a.

The heat dissipation structure 164 includes a base portion 1642 and a plurality of fins 1644 protruding from the base portion 1642, the plurality of fins 1644 being parallel to each other and extending parallel to the base portion 1642; on the other hand, the plurality of fins 1644 extend along a first direction D1 (shown in fig. 4 with an arrow) and a second direction D2 (shown in fig. 4 with a double arrow), respectively. The plurality of fins 1644 form a receiving space to receive the light guide 168 through the height difference. Please also refer to fig. 5. The plurality of fins 1644 include a first fin 1644a and at least one second fin 1644b, the first fin 1644a protrudes relative to the base 1642 than the second fin 1644b such that a first receiving space 1646 (indicated in fig. 5 by a dashed frame) is formed above the at least one second fin 1644b, and the first receiving space 1646 extends parallel to the first fin 1644a and the at least one second fin 1644 b. In the embodiment, the base portion 1642 is substantially in a flat plate shape, a protruding height H1 of the first fin 1644a from the upper surface 1642a of the base portion 1642 in the first direction D1 is greater than a protruding height H2 of the second fin 1644b from the upper surface 1642a of the base portion 1642 in the first direction D1, so that a first accommodating space 1646 is formed between a portion of the first fin 1644a protruding from the second fin 1644b and the at least one second fin 1644b, and the first accommodating space 1646 extends along the second direction D2. In addition, in practice, in cooperation with the structure of the upper surface 1642a of the base portion 1642, the protrusion height H1 of the first fin 1644a may be smaller than the protrusion height H2 of the second fin 1644b, so that the first fin 1644a may still protrude relative to the second fin 1644b, and the first accommodating space 1646 may also be formed, which is not described herein again.

In this embodiment, the fin 1644 may be a stamped metal part and may be secured to the upper surface 1642a of the base 1642 by soldering, thermally conductive glue, adhesive glue, or other means (e.g., the base 1642 forms a slot into which one side of the fin 1644 snaps). Also, the adjacent fins 1644 are connected to each other to increase the overall structural strength of the plurality of fins 1644. Taking the first fin 1644a and the adjacent second fin 1644b as an example, the first fin 1644a has a substantially L-shaped overall structure and extends along the second direction D2. The first fin 1644a includes a first plate 16444 and a first fixing portion 16442, and the first fin 1644a is fixed to the base portion 1642 via the first fixing portion 16442. The second fins 1644b have a generally ㄈ -shaped configuration throughout and extend in the second direction D2. The second fin 1644b includes a second plate 16448, a second fixing portion 16446 and a top portion 16449, the second fixing portion 16446 and the top portion 16449 are connected to two opposite sides of the second plate 16448, and the second fin 1644b is fixed to the base portion 1642 through the second fixing portion 16446. The first fin 1644a further includes a first coupling portion 16450 disposed on the first plate 16444, and the second fin 1644b correspondingly includes a second coupling portion 16452. The first coupling portion 16450 is coupled to the second coupling portion 16452, wherein the first coupling portion 16450 is a notch, the second coupling portion 16452 is a lug, and the first coupling portion 16450 and the second coupling portion 16452 are coupled by being inserted into the notch through the lug. In practice, the first connecting portion 16450 may be a protrusion, and the second connecting portion 16452 may be a notch. In addition, in the present embodiment, the first fin 1644a includes another connecting portion 16451 for connecting with another adjacent fin 1644 (located on the other side of the first fin 1644a relative to the second fin 1644 b). Similarly, the second fin 1644b includes another junction 16453 for connecting with another adjacent fin 1644 (located on the other side of the second fin 1644b relative to the first fin 1644 a). In the present embodiment, the connecting portion 16451 has the same structure as the second connecting portion 16452, and the connecting portion 16453 has the same structure as the first connecting portion 16450; however, the method is not limited thereto.

In addition, in the present embodiment, the plurality of fins 1644 further includes a third fin 1644c disposed adjacent to the at least one second fin 1644b and opposite to the first fin 1644 a. The third fin 1644c protrudes from the base 1642 than the second fin 1644b, and a protrusion height H3 of the third fin 1644c in the first direction D1 from the upper surface 1642a of the base 1642 is greater than a protrusion height H2 of the second fin 1644b in the first direction D1 from the upper surface 1642a of the base 1642, so that the first fin 1644a, the at least one second fin 1644b and the third fin 1644c together form a first accommodating space 1646. The plurality of fins 1644 further includes a fourth fin 1644d, at least one fifth fin 1644e and a sixth fin 1644f, and the fourth fin 1644d, the at least one fifth fin 1644e and the sixth fin 1644f together form a second accommodating space 1648 (indicated by a dashed frame in fig. 5). In structural logic, the fourth fin 1644d, the fifth fin 1644e and the sixth fin 1644f are the same as the first fin 1644a, the second fin 1644b and the third fin 1644c, so that other descriptions of the fourth fin 1644d, the fifth fin 1644e and the sixth fin 1644f are omitted for brevity.

In addition, in the embodiment, the base portion 1642 can be implemented by a metal plate (e.g., copper plate, aluminum plate, etc.), but the implementation is not limited thereto. For example, the base portion 1642 may be implemented by a combination structure of a metal plate and a heat pipe, or by a heat conductive plate (or a plate-shaped heat pipe), or by another object having a heat transfer function. In addition, the base 1642 and the fins 1644 may be implemented as a single structure, such as by aluminum extrusion, die casting, or other suitable manufacturing methods.

As shown in fig. 3 and 4, the light guide member 168 includes a first light guide cylinder 1682, a second light guide cylinder 1684, a connecting portion 1686 and a fixing structure 1688. The first light guide posts 1682 and the second light guide posts 1684 are parallel to each other and extend along the second direction D2. The connecting portion 1686 connects the first light guide cylinder 1682 and the second light guide cylinder 1684 in a direction perpendicular to the first direction D1 and the second direction D2. The light guide member 168 is disposed above the heat dissipation structure 164, wherein the first light guide cylinder 1682 and the second light guide cylinder 1684 are respectively accommodated in the first accommodating space 1646 and the second accommodating space 1648 (as shown by the dashed line frame in fig. 5), and the first light guide cylinder 1682 and the second light guide cylinder 1684 are parallel to the fins 1644. In practice, the protruding heights H1 and H2 of the fins 1644 can be set such that the first light guiding columns 1682 and the second light guiding columns 1684 are completely accommodated in the first accommodating space 1646 and the second accommodating space 1648. This configuration can increase space utilization and also benefit the heat dissipation efficiency of the fins 1644. In addition, since the first light guide posts 1682 and the second light guide posts 1684 are parallel to the fins 1644, the influence of the first light guide posts 1682 and the second light guide posts 1684 on the flow of the heat dissipation air flowing through the fins 1644 can be reduced.

In addition, in the embodiment, the third fin 1644c and the fourth fin 1644d are adjacently disposed and have a gap 1644g and a gap 1644h, respectively, and the first accommodating space 1646 and the second accommodating space 1648 are communicated through the gaps 1644g and 1644 h. The connecting portion 1686 passes through the notches 1644g and 1644h to connect the first light guiding cylinder 1682 and the second light guiding cylinder 1684. When the connecting portion 1686 does not overlap the fin 1644 in the first direction D1, the notches 1644g and 1644h are also omitted. In addition, in implementation, if more fins 1644 are disposed between the first accommodating space 1646 and the second accommodating space 1648, the fins 1644 form gaps, so that the first accommodating space 1646 and the second accommodating space 1648 can communicate with each other through the gaps (including the gaps 1644g and 1644 h). Similarly, if only a single fin is disposed between the first receiving space 1646 and the second receiving space 1648 (i.e. the third fin 1644c and the fourth fin 1644d are the same fin), for example, as shown in fig. 7, only the third fin 1644c is disposed between the first receiving space 1646 and the second receiving space 1648, the gap 1644g connects the first receiving space 1646 and the second receiving space 1648, and the connecting portion 1686 (not shown in fig. 7) passes through the gap 1644g to connect the first light guiding cylinder 1682 and the second light guiding cylinder 1684.

In addition, as shown in fig. 3 and fig. 5, in the present embodiment, the heat dissipation structure 164 includes a plurality of accommodating spaces (including a first accommodating space 1646 and a second accommodating space 1648), and the light guide member 168 correspondingly includes a plurality of light guide cylinders (including a first light guide cylinder 1682 and a second light guide cylinder 1684), which are respectively accommodated in the corresponding accommodating spaces. In practice, the number of the light guiding columns and the number of the accommodating spaces are not limited to the same. For example, the accommodating space can be enlarged to accommodate a plurality of light guide cylinders. In addition, in practice, the accommodating spaces are not limited to the same size, and the light guide cylinders are not limited to the same size. In addition, the thickness of the connecting portion 1686 (as viewed in fig. 5) can be further reduced to further reduce the influence of the connecting portion 1686 on the flow of the heat dissipating airflow passing through the fins 1644.

Referring to fig. 2 to 4, the light guide 168 is fixed to the connector housing 162 via the fixing structure 1688. The connector housing 162 includes a plurality of clips 1624, the fixing structure 1688 includes a plurality of protrusions 16882 and an abutting portion 16884, the protrusions 16882 are clipped into the clips 1624, and the abutting portion 16884 abuts against an outer sidewall 162f of the connector housing 162 at a rear side (opposite to the inlet 1622 a). However, the implementation is not limited thereto, for example, the light guide 168 may be directly fixed or placed on the fin 1644. For the first light guiding cylinder 1682, the light guiding member 168 further includes an incident portion 1690 and an emergent portion 1692 respectively connected to the two ends 1682b, 1682a of the first light guiding cylinder 1682. The light incident portion 1690 extends toward the connector housing 162 (or the circuit board 12) to connect with the light source 122, so as to receive light emitted by a corresponding light emitting element (such as but not limited to a light emitting diode) in the light source 122 (such as but not limited to a light emitting diode). The light is guided by the first light guiding cylinder 1682 and can exit the light guiding member 168 through the light exit portion 1692. Similarly, for the second light pillar 1684, the light guide member 168 also includes corresponding light incident portion and light emergent portion, which have the same structure as the light incident portion 1690 and the light emergent portion 1692, and therefore, the structure thereof is not described herein again. In addition, in the embodiment, the light source 122 includes a hook structure 1222 hooking (the abutting portion 16884 of) the fixing structure 1688, so as to fix the light source 122 on the abutting portion 16884 of the light guiding pillar, which is helpful for fixing the light guiding member 168 and also is helpful for the light incident portion 1690 to be stably connected with the light source 122.

Please refer to fig. 1 to 6, 8 and 9. The elastic fasteners 166 are n-shaped in the second direction D2 and are n-shaped in the first direction D1. The elastic clip 166 includes two engagement portions 1662 and two elastic portions 1664, and the two elastic portions 1664 are connected to the two engagement portions 1662. The elastic fasteners 166 cross the two heat dissipation structures 164 and are connected to the connector housing 162 through the two connecting portions 1662 to elastically sandwich (elastically clamp) the two heat dissipation structures 164 between the two elastic portions 1664 and the outer sidewall 162a of the connector housing 162. The engaging portion 1662 is engaged with the hooks on the two outer sidewalls 162b and 162d of the connector housing 162 through a hole, but the implementation is not limited thereto, for example, the elastic fastener 166 is also pivotally connected at one end and engaged with the other end to mount the two heat dissipation structures 164 on the connector housing 162. The first fin 1644a, the third fin 1644c, the fourth fin 1644d and the sixth fin 1644f respectively have two notches 1644i, 1644j, 1644k and 1644m for the two elastic parts 1664 to pass through, so that the two elastic parts 1664 elastically abut against the fins 1644 and are located between the first light guide cylinder 1682 and the second light cylinder 1684 and the heat dissipation structure 164. Since the second fin 1644b and the fifth fin 1644e are shorter than the first fin 1644a, the third fin 1644c, the fourth fin 1644d and the sixth fin 1644f, the elastic portion 1664 can directly pass through the upper portion thereof without forming a gap structure, but the implementation is not limited thereto. For example, all fins 1644 form indentations for the elastic portion 1664 to pass through; also for example, the base portion 1642 is not provided with the fins 1644 corresponding to the portion of the resilient portion 1664, such that the resilient portion 1664 directly abuts against the base portion 1642 of the heat dissipation structure 164 to mount the heat dissipation structure 164 to the connector housing 162.

In addition, in the embodiment, the outer side wall 162a of the connector housing 162 has two windows 1626 corresponding to the two slots 1622. The base portion 1642 of the heat dissipation structure 164 has a downward projection 1642b partially entering the corresponding slot 1622 via the corresponding window 1626. The elastic fastener 166 is elastic, so that the base portion 1642 (or the heat dissipation structure 164) can be allowed to move relative to the window 1626. In addition, the first light guiding cylinder 1682, the at least one second fin 1644b and the elastic fastener 166 are disposed at an interval in a direction perpendicular to the base portion 1642, that is, a gap exists between the first light guiding cylinder 1682, the at least one second fin 1644b and the elastic fastener 166 in the first direction D1; this also applies to the structural relationship between the other light guide columns of the light guide 168 and the fins 1644, which is not described herein. The gap allows the heat dissipation structure 164 and the elastic portion 1664 to move in the first direction D1 relative to the light guide 168 (and the connector housing 162). When an external connector (shown in fig. 9 by a dashed line) is inserted into the slot 1622, the external connector can contact and push the protrusion 1642b upward, so that heat generated during operation of the external connector can be dissipated through the heat dissipation structure 164.

Please refer to fig. 1 to 4. In the present embodiment, the electrical connector housing assembly 16 further includes two outer covers 170, which respectively correspond to the two heat dissipation structures 164. The cover 170 covers the fins 1644 (e.g., the first fins 1644a, the second fins 1644b, etc.), the accommodating spaces formed by the fins 1644 (e.g., the first accommodating space 1646, the second accommodating space 1648, etc.), and the light guide columns (e.g., the first light guide columns 1682, the second light guide columns 1684, etc.) of the light guide 168. In practice, the housing 170 also has the effect of protecting the structure (e.g., the light guide 168, the fins 1644, etc.), increasing the guiding effect of the heat dissipation airflow, shielding the light (e.g., the light leakage from the first light guide posts 1682), and so on. In the present embodiment, the outer cover 170 is connected to the outermost fins 1644 (e.g., the first fins 1644a) of the corresponding heat dissipation structure 164, but the implementation is not limited thereto. For example, the cover 170 may be connected to the second fins 1644b (e.g., a connecting portion extending downward inside the cover 170 to connect with the second fins 1644 b), the base 1642, or the connector housing 162.

Please refer to fig. 10 and 11. An electronic device 3 according to an embodiment of the present invention (such as but not limited to a computer host) includes a device housing 32, a circuit board 34 (such as but not limited to a system motherboard), and the electrical connector socket 14 and the electrical connector socket assembly 16 as described above.

For other descriptions of the electrical connector 14 and the electrical connector housing assembly 16, please refer to the related descriptions, which are not repeated herein. In the present embodiment, the device housing 32 includes a panel 322 (e.g., integrated with the rear side plate structure), and the panel 322 has an opening 3222 and a light-permeable structure 3224 (indicated by a dashed-line frame). The light-permeable structure 3224 is implemented by a plurality of through holes, but not limited thereto, for example, by a plurality of light-permeable members embedded in the panel 322, or by a single window or a single light-permeable member; wherein the light-transmitting member is not limited to being completely transparent. The electrical connector housing assembly 16 is disposed toward the opening 3222 and the light permeable structure 3224, such that the inlet 1622a of the slot 1622 of the connector housing 162 is aligned with the opening 3222, and the light emitting portion (including the light emitting portion 1692 and the like) of the light guiding cylinder of the light guiding member 168 is aligned with the light permeable structure 3224 (or the corresponding through hole). Thus, the light emitted from the light-guiding member 168 through the light-emitting portion 1692 can be observed from the outside of the device housing 32 through the light-transmitting structure 3224, thereby generating an optical indication effect (e.g., according to the operation status of the electrical connector 14).
