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 the application of the plug and socket connector combination, the heat dissipation fins are generally directly fixed on the housing of the socket for heat dissipation. However, when the plug is connected to the socket and is operated, the heat source is generally concentrated inside the plug, and if the heat accumulation inside the plug is too high, the plug will fail, and therefore, the heat generated inside the plug needs to be transferred to the housing of the socket and can be dissipated through the heat dissipation fins. Also, the housing of the socket is generally not in direct contact with the heat generating source, and the efficiency of transferring heat generated by the heat generating source to the housing of the socket may be poor. Therefore, the manner of fixing the heat dissipation fins only on the housing of the socket has a limited heat dissipation effect on the connector.

Disclosure of Invention

In view of the problems in the prior art, the present invention provides an electrical connector housing assembly having a heat dissipation structure, wherein a heat pipe of the heat dissipation structure can extend into a connector housing to improve the heat dissipation efficiency.

The shell and seat assembly of the electric connector comprises a connector shell, a heat dissipation structure and an elastic fastener. The connector housing forms a slot and has an outer side wall, the outer side wall has a window, and the window is communicated with the slot. The heat dissipation structure is arranged on the outer side wall and comprises a heat pipe, the heat pipe is arranged on the outer side of the outer side wall and is provided with a heat absorption section corresponding to the window, and the heat absorption section extends parallel to the outer side wall and partially enters the slot through the window. The elastic fastener is connected to the connector shell so as to elastically clamp the heat dissipation structure between the fastener and the outer side wall, and the heat absorption section can move relative to the window. Therefore, when a plug-in module is inserted into the slot, the heat absorption section can move relative to the outer side wall through the elasticity of the elastic fastener to be in pressed direct contact with the plug-in module, and further the heat dissipation efficiency is improved.

Another objective of the present invention is to provide an electrical connector having the aforementioned shell assembly with a heat dissipation structure, so that the heat dissipation efficiency is improved.

The electrical connector according to the present invention comprises a circuit board, an electrical connector socket and the electrical connector housing assembly. The electric connector shell seat assembly is fixed on the circuit board. The electrical connector is electrically connected to the circuit board and located in the connector housing and exposed out of the slot. Similarly, when a plug-in module is inserted into the slot and combined with the electrical connection seat, the heat absorption section can move relative to the outer side wall through the elasticity of the elastic fastener to be in pressed direct contact with the plug-in module, and therefore the heat dissipation efficiency is improved.

Another objective of the present invention is to provide an electronic device having the aforementioned electrical connector housing assembly with a heat dissipation structure, wherein the heat dissipation structure is thermally coupled to a structural side plate of the device housing, so as to improve heat dissipation efficiency.

The electronic device according to the present invention comprises a device housing, a circuit board, an electrical connector socket, and the electrical connector socket assembly. The device shell forms an accommodating space and comprises a structural side plate. The circuit board is arranged in the accommodating space. The electric connector shell base combination is fixed on the circuit board, and the heat pipe is thermally coupled with the structural side plate. The electrical connection seat is electrically connected to the circuit board, is positioned in the connector shell and is exposed out of the slot. Similarly, when a plug-in module is inserted into the slot and combined with the electrical connection seat, the heat absorption section can move relative to the outer side wall through the elasticity of the elastic fastener to directly contact the plug-in module under pressure. The heat pipe transfers the absorbed heat to the structural side plate to improve the heat dissipation efficiency.

The advantages and spirit of the present invention can be further understood by the following detailed description of the invention and the accompanying drawings.

Detailed Description

Please refer to fig. 1 to 3. An electrical connector 1 according to an embodiment of the present invention includes a circuit board 12, two

electrical connection sockets

14a, 14b and an electrical connector housing assembly 16. The electrical connector housing assembly 16 is secured to the circuit board 12. The

electrical connectors

14a, 14b are electrically connected to the circuit board 12 and are located within the electrical connector housing assembly 16, and are shown as solid squares for simplicity of illustration. In practice, the

electrical connectors

14a, 14b may be structurally integrated into a single component for ease of assembly. The electrical connector housing assembly 16 includes a connector housing 162, a heat sink 164 and two elastic fasteners 166. 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 accommodating space 1620 to divide the accommodating space 1620 into a first slot 1622 and a second slot 1624, and the

electrical connectors

14a and 14b are respectively exposed out of the first slot 1622 and the second slot 1624. The first slot 1622 has a first entrance 1622a and the second slot 1624 has a second entrance 1624 a. The outer sidewall 162a has a first window 1626 and a second window 1628, which are respectively connected to the first slot 1622 and the second slot 1624.

The heat dissipation structure 164 is disposed on the outer sidewall 162a, and the elastic fastener 166 is connected to the connector housing 162 to elastically clamp the heat dissipation structure 164 between the elastic fastener 166 and the outer sidewall 162 a. The heat dissipation structure 164 includes a heat pipe 1642, the heat pipe 1642 is disposed outside the outer sidewall 162a and has a first heat absorption section 1642a, a second heat absorption section 1642b and a connection section 1642c, the connection section 1642c connects the first heat absorption section 1642a and the second heat absorption section 1642b, the first heat absorption section 1642a is disposed corresponding to the first window 1626 and extends parallel to the outer sidewall 162a and partially enters the first slot 1622 through the first window 1626, and the second heat absorption section 1642b is disposed corresponding to the second window 1628 and extends parallel to the outer sidewall 162a and partially enters the second slot 1624 through the second window 1628. For simplicity of illustration, the heat pipe 1642 is shown in solid form. In practice, the heat pipe 1642 may be a heat pipe with a substantially flat and oval cross-section, and a protruding structure is formed at two end portions (for example, the heat pipe is shaped by a shaping process, such as extruding the heat pipe through a mold), the two end portions serve as the first heat absorbing section 1642a and the second heat absorbing section 1642b, the protruding structure can enter the first slot 1622 and the second slot 1624, and the middle portion serves as the connecting section 1642 c. Alternatively, three tubes are individually shaped to form the first heat absorbing section 1642a, the second heat absorbing section 1642b and the connecting section 1642c, and then joined to form the heat pipe 1642.

The heat dissipation structure 164 further comprises a heat dissipation member thermally coupled to the heat pipe 1642. In the present embodiment, the heat sink includes a base 1644 and a plurality of fins 1646 extending from the base 1644. The base 1644 is thermally coupled to the heat pipe 1642. The base 1644 has a first recess 1644a and a second recess 1644b, the first heat absorbing section 1642a is accommodated in the first recess 1644a, and the second heat absorbing section 1642b is accommodated in the second recess 1644 b. In practice, the first heat sink segment 1642a and the second heat sink segment 1642b are soldered in the first recess 1644a and the second recess 1644b, for example, the gap between the first recess 1644a and the first heat sink segment 1642a is filled with solder. In addition, the connecting section 1642c is also soldered to the base 1644. In practice, the fixing may be performed by using an adhesive or a thermal adhesive (not described in detail).

The elastic fasteners 166 cross the heat sink structure 164 and are connected to the

outer sidewalls

162b and 162 d. In the embodiment, the elastic fastener 166 is substantially of a n-shaped structure, and has two

engaging holes

166a and 166b at two ends thereof, and two

engaging hooks

162f and 162g on the

outer sidewalls

162b and 162d, respectively. The resilient latch 166 is releasably engaged with the

outer sidewalls

162b, 162d by the

hooks

162f, 162g engaging the

latch holes

166a, 166 b. In practice, the elastic fastener 166 is also used to install the heat dissipation structure 164 in the connector housing 162 in a manner of being pivoted at one end and being clamped at the other end. In addition, in the present embodiment, the elastic fastener 166 is elastically clamped between the elastic fastener 166 and the outer sidewall 162a through the plurality of fins 1646 of the heat dissipation structure 164. On the other hand, the base 1644 is not provided with the fins 1646 corresponding to the elastic fasteners 166, and the middle portion of the elastic fastener 166 connecting the two end portions can directly abut against the base 1644. By the elasticity of the elastic fastener 166, the clamped heat dissipating structure 164 can still be forced to move (or float) in design, in other words, the first heat absorbing section 1642a can move relative to the first window 1626, and the second heat absorbing section 1642b can move relative to the second window 1628.

For example, in the process of inserting the plug module (i.e. the connector matching with the electrical connector 1, shown in fig. 3 by the dashed box) matching with the electrical connector 14a into the first slot 1622 from the first inlet 1622a and engaging with the electrical connector 14a, since the first heat absorbing section 1642a partially enters the first slot 1622, the plug module contacts the first heat absorbing section 1642a and pushes the first heat absorbing section 1642a, so that the first heat absorbing section 1642a moves outward (i.e. moves upward in fig. 3, or moves perpendicular to the extending direction of the outer sidewall 162a) relative to the first window 1626. Due to the elasticity of the elastic fastener 166, a contact force can be kept between the first heat absorption section 1642a and the plug-in module, which is beneficial to the heat conduction between the plug-in module and the first heat absorption section 1642 a. In this embodiment, a portion of the first heat absorbing section 1642a entering the first slot 1622 has a contact plane 1642d matching with a contour of the plug module, which is beneficial to heat conduction between the plug module and the first heat absorbing section 1642 a. The above description also applies to the second heat sink section 1642b, which is not described in detail. In addition, the heat pipe 1642 utilizes the phase change of the working fluid to rapidly transfer heat from the plug module to the base 1644, and then dissipated through the fins 1646.

In the present embodiment, the heat dissipation structure 164 is disposed on the upper side (i.e., the outer sidewall 162a) of the connector housing 162 in cooperation with the arrangement (i.e., horizontal arrangement) of the first slot 1622 and the second slot 1624. In practice, if the first slot 1622 and the second slot 1624 are vertically aligned, the heat dissipation structure 164 can be disposed on the left side or the right side (i.e., the outer sidewall 162d or the outer sidewall 162b) of the connector housing 162. In addition, in the present embodiment, the electrical connector 1 is illustrated by using a dual slot, and the heat dissipation structure 164 provides a heat dissipation effect for both the first slot 1622 and the second slot 1624, but the implementation is not limited thereto. As in the previous embodiments and the related description, the heat pipe 1642 partially enters the first slot 1622 through the first window 1626, so that the heat pipe 1642 can directly contact the plug module to rapidly transfer heat from the plug module to the heat sink (which includes the base 1644 and the plurality of fins 1646 in this embodiment) and dissipate the heat. Therefore, in practice, the architecture can be applied to an electrical connector with a single slot or more slots, and is modified according to the requirements of the actual electrical connector structure based on the foregoing embodiments and the related descriptions, which will not be described in detail herein. For example, the heat sink structure 164 can omit the base 1644 and the fins 1646 thereon, and the connecting portion 1642c is sleeved with a plurality of fins (e.g., a copper sheet having a hole therein for being sleeved on the connecting portion 1642 c) to serve as a heat sink. For example, in an electrical connector with a single slot, one end of the heat pipe is used for absorbing heat from a plug module, and the other end of the heat pipe can be directly sleeved with a plurality of fins to serve as heat dissipation members, and a base is not needed.

outer sidewalls

362b and 362d in the accommodating space 3620 to divide the accommodating space 3620 into a first slot 3622 and a second slot 3624, the

The outer sidewall 362d has a first window 3626 and a second window 3628 respectively connected to the first slot 3622 and the second slot 3624. In the embodiment, the first slot 3622 and the second slot 3624 are vertically arranged, and the

electrical connectors

34a and 34b are structurally integrated into a single component, but the implementation is not limited thereto.

The heat dissipation structure 364 is disposed on the outer sidewall 362d, and the elastic fastener 366 is engaged with the connector housing 362 to elastically clamp the heat dissipation structure 364 between the elastic fastener 366 and the outer sidewall 362 d. In this embodiment, one end of the elastic fastener 366 is pivotally connected to the connector housing 362, and the other end is engaged with the connector housing 362; however, in practice, the elastic fastener 366 may also be engaged with the elastic fastener 166 and the connector housing 162, which is not described in detail herein. The heat dissipation structure 364 includes a heat pipe 3642, the heat pipe 3642 is disposed outside the outer sidewall 362d and has a first heat absorption section 3642a, a second heat absorption section 3642b, a connection section 3642c and an extension section 3642d, the connection section 3642c is connected to the first heat absorption section 3642a and the second heat absorption section 3642b, and the extension section 3642d extends from one end of the first heat absorption section 3642 a. The first heat sink segment 3642a extends parallel to the outer side wall 362d and partially into the first slot 3622 via the first window 3626, and the second heat sink segment 3642b extends parallel to the outer side wall 362d and partially into the second slot 3624 via the second window 3628. For the detailed description of the structures of the first heat absorption section 3642a and the second heat absorption section 3642b, reference may be made to the related description of the first heat absorption section 1642a and the second heat absorption section 1642b, which is not repeated herein.

Similarly, the elastic fasteners 366 can generate an elastic structure constraint effect on the heat pipe 3642, which is the same as the elastic structure constraint effect generated by the elastic fasteners 166 on the heat pipe 1642, and will not be described again. In addition, the portion of the heat pipe 3642 entering the first slot 3622 and the second slot 3624 has a contact plane, which is matched with the outline of the plug module (shown in fig. 6 by a dashed frame) for being inserted into the first slot 3622 and the second slot 3624, so as to facilitate the heat conduction between the plug module and the heat pipe 3642. In addition, in practice, the heat dissipation structure 364 may also include a base and a plurality of fins extending from the base, and the heat pipe 3642 is also thermally coupled to the base (e.g., the base 1644, the fins 1646 and the heat pipe 1642 are configured as described above), so as to enhance heat dissipation.

The extended section 3642d of the heat pipe 3642 is thermally coupled (e.g., fixed by soldering) to the structural side plate 302 a. The heat absorbed by the first heat absorbing section 3642a and the second heat absorbing section 3642b can be conducted to the structural side plate 302a via the extension 3642d for dissipation. In practice, the extension 3642d may be thermally coupled to other structural side plates (e.g., the structural side plate 302c) of the lower housing 302, so as to dissipate heat through the device housing 30.
