Description

Electrical connector housing assembly and electrical connector

The present invention relates to an electrical connector, in particular to an electrical connector with a detachable heat dissipation structure.

Electrical connectors have been widely used in environmental requirements for power or signal connections, such as connecting electronic host devices to external devices. As electrical connectors experience a dramatic increase in transmission speeds, so does the amount of heat generated. In this regard, a heat dissipation structure (such as a heat dissipation fin) can be arranged on the housing of the connector to facilitate heat dissipation. The heat dissipation structure of some connectors adopts a detachable design. For example, the heat dissipation structure includes a heat absorption plate and a plurality of fins extending upward from the heat absorption plate, and then the heat absorption plate and the fins are fixed to the casing by elastic fasteners. Wherein, in some connectors, the elastic fasteners span across and press against the fins, so that the upward extension of the fins is limited, and the elastic fasteners also affect the heat dissipation effect of heat convection on the fins to a certain extent. In some connectors, the elastic fasteners only straddle and press against the heat absorbing plate, and the portion of the heat absorbing plate pressed by the elastic fasteners is not provided with fins. This structure also limits the overall heat dissipation effect to a certain extent. When the disposition space of the heat dissipation structure is limited, any structural configuration that reduces the space for disposing the fins will have a significant adverse effect on the overall heat dissipation effect of the heat dissipation structure.

One object of the present invention is to provide an electrical connector housing assembly with a removable heat sink. One side of the heat sink is detachably fixed to the connector housing, so as to reduce the unfavorable influence of the fixing structure on the heat dissipation effect of the heat sink.

The electrical connector housing assembly according to the present invention includes a connector housing, a heat sink and a fixing member. The connector housing forms a slot space and has an outer side wall. The heat sink includes a base and a plurality of fins, the base has a top surface, and the plurality of fins extend from the top surface. The top surface has a side area in an extending direction, and the plurality of fins extend above the side area to form a slot with the side area. The slot has two end openings and one side opening, and the side opening extends to the two end openings. The fixing piece passes through the slot and protrudes from the two-end openings to be removably connected to the connector housing, so as to removably fix the base to the outer side wall.

Another object of the present invention is to provide an electrical connector with the aforementioned electrical connector housing assembly, so that the detachable fixing structure of the heat sink can be used to reduce adverse effects on the heat dissipation effect of the heat sink.

The electrical connector according to the present invention includes a circuit board, an electrical connector housing set and an electrical connection seat. The electrical connector housing is assembled and fixed on the circuit board and includes a connector housing, a heat sink and a fixing piece. The connector housing forms a slot space and has an outer side wall. The heat sink includes a base and a plurality of fins, the base has a top surface, and the plurality of fins extend from the top surface. The top surface has a side area in an extending direction, and the plurality of fins extend above the side area to form a slot with the side area. The slot has two end openings and one side opening, and the side opening extends to the two end openings. The fixing piece passes through the slot and protrudes from the two-end openings to be removably connected to the connector housing, so as to removably fix the base to the outer side wall. The electrical connection base is electrically connected to the circuit board, is located in the connector housing, and is self-exposed from the slot space.

Compared with the prior art, in the electrical connector housing assembly and the electrical connector according to the present invention, the heat sink is fixed to the connector housing through one side of the base, so the number of pairs of fixing parts can be reduced. The heat dissipation effect of the radiator is adversely affected. In addition, the radiator still has fins above the side of the base, so the space above the side of the base can be used to dissipate heat, which also helps to reduce the adverse effect of the fixing element on the heat dissipation effect of the radiator.

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

See Figures 1 to 6. An electrical connector 1 according to an embodiment of the present invention includes a circuit board 12 , two electrical connection sockets 14 a and 14 b and an electrical connector housing assembly 16 .

The connector housing 162 includes an outer side wall 1622 and an inner partition 1624 . The outer side wall 1622 includes a top wall 1622a, a first side wall 1622b, a bottom wall 1622c (opposite to the top wall 1622a) and a second side wall 1622d (opposite to the first side wall 1622b) connected in sequence to form a slot space 162a. The inner partition 1624 is disposed in the slot space 162a, and two sides thereof are connected to the top wall 1622a and the bottom wall 1622c to divide the slot space 162a into a first slot 162b and a second slot 162c. The electrical connection sockets 14a and 14b are located in the connector housing 162 and exposed to the first slot 162b and the second slot 162c, respectively. Therefore, the electrical connector housing assembly 16 can be used for the insertion of two matching connectors, that is, the first slot 162b and the second slot 162c are respectively inserted into the first slot 162b and the second slot 162c in an insertion direction D1 (indicated by an arrow in the figure) to connect with The corresponding electrical connection sockets 14a and 14b are connected.

The first heat sink 164 includes a first base 1642 and a plurality of first fins 1644 fixed on the first base 1642 . The first base 1642 has a first top surface 1642a, and the first top surface 1642a has a first side region 1642b in an extending direction D2 (indicated by a double arrow in the figure), opposite to the first side region 1642b. A second side area 1642c, and a fin connecting area 1642d between the first side area 1642b and the second side area 1642c (the three are separated by dotted lines), the plurality of first fins 1644 are fixedly disposed on The fin connection area 1642d extends upwardly from the fin connection area 1642d. The plurality of first fins 1644 also extend parallel to the first top surface 1642a, and extend above the first side region 1642b and the second side region 1642c to connect with the first side region 1642b and the second side region, respectively A first slot 1646 and a second slot 1648 are formed at 1642c. The first slot 1646 has two first end openings 1646a and a first side opening 1646b, and the first side opening 1646b extends to the two first end openings 1646a. The second slot 1648 has two second end openings 1648a and a second side opening 1648b, and the second side opening 1648b extends to the two second end openings 1648a.

The first fixing piece 168 passes through the first slot 1646 and protrudes from the two first end openings 1646a to be removably connected to the connector housing 162, and the second fixing piece 170 passes through the second slot 1648 and protrudes from the connector housing 162. The two second end openings 1648a are removably connected to the connector housing 162, so that the first fixing member 168 and the second fixing member 170 together removably fix the first base portion 1642 to the outer side wall 1622b (ie, The corresponding first slot 162b is disposed on the top wall 1622a). Therefore, the first fixing member 168 and the second fixing member 170 are substantially close to the first base portion 1642, which can avoid or greatly reduce the influence on the heat dissipation airflow, especially when there is a forced airflow (for example, a fan is provided on the front side of the electrical connector 1 to The airflow parallel to the first fins 1644 is generated), and the forced airflow can smoothly flow through the plurality of first fins 1644 . In addition, in this embodiment, the first fixing member 168 can be separated from the first heat sink 164 through the first side opening 1646b, and the second fixing member 170 can be separated from the first heat sink 164 through the second side opening 1648b. This structural configuration allows the first heat sink 164 to be designed separately from its fixing structure (ie, the first fixing member 168 and the second fixing member 170 ). The fixing structure can be designed for different connector housings, and the first heat sink 164 can be connected to the connection. The scope of application of the housing.

In addition, in this embodiment, the first fixing member 168 includes two engaging portions 168a, 168b and an elastic pressing portion 168c connecting the two engaging portions 168a, 168b. When the first fixing member 168 fixes the first base portion 1642 on the top wall 1622a, the elastic pressing portion 168c is located in the first slot 1646 and elastically presses against the first side (of the first top surface 1642a of the first base portion 1642). In the edge region 1642b, the engaging portions 168a, 168b protrude from the two first end openings 1646a and are removably engaged to the outer side wall 1622 (of the connector housing 162). In this embodiment, the first heat sink 164 and the second heat sink 166 are arranged side by side on the outer side wall 1622 perpendicular to the insertion direction D1. In the first fixing member 168, the engaging portion 168a (implemented with a hole) is detachably connected to a retaining structure (implemented with an outwardly protruding elastic piece) on the first side wall 1622b, and the engaging portion 168b (implemented with a A hook is implemented) detachably connected to a connecting portion 1622e (which is located between the first radiator 164 and the second radiator 166 and is also detachable from the third fixing member 172) fixed on the top wall 1622a In addition to the connection); but in practice it is not limited to this. In practice, the structures of the connecting portions 168a and 168b depend on the actual application product. For example, in the electrical connector of one embodiment, the electrical connector housing assembly only provides a single matching connector plug, and the fixing element The U-shaped structure design can be adopted, and the structures at both ends can be designed as the structure of the aforementioned connecting portion 168a. For another example, in the electrical connector of an embodiment, both ends of the fixing member are detachably connected to the top wall, and the structures of both ends can be designed as the structure of the aforementioned connecting portion 168b. In addition, in this embodiment, the structure of the second fixing member 170 is the same as that of the first fixing member 168 . Therefore, for other descriptions of the second fixing member 170 , you can directly refer to the related descriptions of the first fixing member 168 and its modifications herein. , without further elaboration.

In addition, in this embodiment, the first fixing member 168 and the second fixing member 170 span the first base portion 1642 on the front and rear sides of the first base portion 1642 (relative to the extending direction D2 ) to stably fix the first base portion 1642 on the first base portion 1642 . on the outer side wall 1622b, but not limited to this in practice. In practice, a single fixing member can be used to fix the first heat sink 164 to the connector housing 162. For example, a restraining structure is provided on the connector housing 162 (for example, a limiting groove is provided on the top wall 1622a). The rear side of a base portion 1642 is inserted into the limiting groove, and the front side of the first base portion 1642 is still fixed by the first fixing member 168 , which can also achieve the effect of stably fixing the first heat sink 164 to the connector housing 162 . In addition, in this embodiment, the structures of the first fixing member 168 and the second fixing member 170 are the same, but the practice is not limited thereto. For example, the second fixing member 170 is changed to a clamping structure (such as a C-shaped clip), which simultaneously clamps the rear side of the first base portion 1642 and the top wall 1622a. This structure configuration can also achieve the fixing effect of the second fixing member 170. . In addition, in the present embodiment, the first base portion 1642 is generally in the shape of a rectangular plate and has a longitudinal direction, which is the same as the extending direction D2 and parallel to the insertion direction D1, but is not limited in practice. For example, in practice, the extending direction D2 can also be defined as the width direction of the first base portion 1642 (ie, perpendicular to the longitudinal direction), or other directions. For another example, in practice, in accordance with the actual product design, the longitudinal direction of the first base portion 1642 may be non-parallel to the insertion direction D1 (eg, forming an acute angle), and the extension direction D2 is not parallel to the insertion direction D1. For another example, in practice, the first fixing member 168 and the second fixing member 170 are not limited to being disposed on opposite sides of the first base portion 1642 .

In this embodiment, the plurality of first fins 1644 are formed by stacking a plurality of metal stamping plates (for example, but not limited to, the adjacent first fins 1644 are engaged with each other in an engaging structure), and are connected to the first base. 1642 Thermal coupling (such as but not limited to soldering). However, it is not limited in practice. For example, the plurality of first fins 1644 and the first base 1642 are integrally formed (eg, fabricated through an aluminum extrusion process or processing a thermally conductive metal block). In addition, in this embodiment, the first base portion 1642 is substantially plate-shaped, and the first top surface 1642a is also flat, but not limited in practice. For example, when the first top surface is convex, the first fin can also be in contact with the corresponding arc surface, thereby realizing thermal coupling, which will not be described in detail. In addition, in this embodiment, the plurality of first fins 1644 extend parallel to the extending direction D2, but the practice is not limited to this. For example, the first fins 1644 extend obliquely with respect to the extending direction D2. In addition, in this embodiment, the plurality of first fins 1644 extend upward perpendicular to the first top surface 1642a, but it is not limited in practice. For example, the first fins 1644 extend obliquely upward from the first top surface 1642a and extend perpendicular to the extending direction D2. In addition, in this embodiment, the plurality of first fins 1644 protrude from the first base portion 1642 parallel to the extending direction D2, which helps to increase the heat dissipation area of the first fins 1644, thereby improving the heat dissipation efficiency. In addition, in this embodiment, the plurality of first fins 1644 cover the entire first top surface 1642a in a direction perpendicular to the first top surface 1642a as a whole. This configuration effectively utilizes the space above the first base portion 1642, and does not Since the first fixing member 168 and the second fixing member 170 are provided, the overall volume of the plurality of first fins 1644 needs to be reduced, so the arrangement of the first fixing member 168 and the second fixing member 170 can be reduced to dissipate heat to the first heat sink 164 effect on efficiency.

In addition, in this embodiment, the top wall 1622a of the outer side wall 1622 has a first window 1622f and a second window 1622g, which correspond to the first heat sink 164 and the second heat sink 166, respectively. As shown in FIG. 6 , the first base 1642 partially protrudes into the first slot 162b of the slot space 162a through the first window 1622f, so that a matching connector (shown in phantom in the figure) is inserted into the first slot 162b 6) can contact the first base 1642 (ie, touch the part protruding into the first slot 162b through the first window 1622f), so that the heat generated by the matching connector during operation is dissipated through the first base 1642. In addition, due to the elasticity of the elastic pressing portion 168c, the first heat sink 164 is allowed to move vertically, so that the matching connector and the (bottom) of the first base portion 1642 can maintain a considerable contact force, which is beneficial to the matching connector Thermal conduction with the first base 1642 .

In this embodiment, the structure of the second heat sink 166 is the same as that of the first heat sink 164 , and the structures of the third fixing member 172 and the fourth fixing member 174 are symmetrical with the first fixing member 168 and the second fixing member 170 . For other descriptions of the radiator 166 , the third fixing member 172 and the fourth fixing member 174 , please refer to the related descriptions of the first heat sink 164 , the first fixing member 168 , the second fixing member 170 and their modifications in this document, unless otherwise stated. Repeat. In short, the second heat sink 166 is disposed adjacent to the first heat sink 164, the second heat sink 166 includes a second base 1662 and a plurality of second fins 1664, the second base 1662 has a second top surface 1662a The plurality of second fins 1664 extend from the second top surface 1662a and form a third slot 1666 and a fourth slot 1668 with the second top surface 1662a on the front and rear sides of the second base 1662 . The third fixing piece 172 and the fourth fixing piece 174 pass through the third slot 1666 and the fourth slot 1668 respectively to span the second base 1662 , so as to jointly detach the second base 1662 corresponding to the second slot 162c Secured to top wall 1622a (of outer side wall 1622). Wherein, one end portion 172a of the third fixing member 172 and one end portion (ie, the connecting portion 168b ) of the first fixing member 168 are connected to the connecting portion 1622e relatively, and the other end portion 172b of the third fixing member 172 and the first fixing member 168 The other end portion (ie, the connecting portion 168a ) is connected to the second side wall 1622d and the first side wall 1622b respectively; the same is true for the fourth fixing member 174 , which will not be repeated. In addition, like the first base 1642, the second base 1662 partially protrudes into the second slot 162c of the slot space 162a through the second window 1622g, so that the mating connector inserted into the second slot 162c can contact the second slot 162c. The bottom of the base portion 1662 allows the heat generated by the matching connector to dissipate through the second base portion 1662 during operation. In addition, the third fixing member 172 and the fourth fixing member 174 also have elasticity, allowing the second heat sink 166 to move vertically, so that the matching connector and the bottom of the second base 1662 can maintain a considerable contact force, which is beneficial to the Thermal conduction between the mating connector and the second base 1662 .

In addition, in this embodiment, the electrical connector housing assembly 16 further includes two light guide structures 176a and 176b, which are respectively disposed on the outer sides of the first side wall 1622b and the second side wall 1622d corresponding to the first slot 162b and the second slot 162c. . A plurality of light sources 122 (such as but not limited to light-emitting diodes) are disposed on the circuit board 12 corresponding to the light guide structures 176a and 176b. The light guide structures 176a and 176b can guide the light emitted by the light sources 122 to the electrical connector housing assembly. 16 on the front side for optical indication. The light guide structures 176a and 176b are fixed in the same manner, and the light guide structure 176a is used as an example for description below. Corresponding to the light guide structure 176a, the outer side wall 1622 has two holding portions 1622h and 1622i protruding outward. The light guide structure 176a is disposed outside the first side wall 1622b through the holding portions 1622h and 1622i. One of the holding portions 1622h passes through a through hole 168d of the first fixing member 168 to hold the light guide structure 176a to avoid structural interference with the first fixing member 168; A fixing member 168 provides the positioning effect.
