[0001] This application relates to the technical field of connectors, and particularly to an electrical connector. Background Art

[0002] Currently, connectors are usually covered by a housing. In order to discharge the heat generated by the connector during operation from the inside of the housing to the outside of the housing, holes are usually opened in the housing. Although this can improve the heat dissipation effect of the connector, the heat dissipation effect of the connector still does not meet the standard. At the same time, another problem is generated, that is, during the signal transmission process of the connector, the electromagnetic waves generated by the connector are easily transmitted from the holes in the housing to the outside, and interfere with adjacent electronic devices, or the electromagnetic waves of adjacent electronic devices are easily introduced from the holes in the housing and interfere with the connector, thereby affecting the signal transmission performance of the connector.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0015] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , which are a perspective view, an exploded view, Figure 1 a cross-sectional view taken along line A-A' in Figure 1 and a cross-sectional view taken along line B-B' in of an electrical connector of an embodiment of the present application; as shown in the figure, the electrical connector 1 of this embodiment includes a housing 10, a circuit board 11, a cable 12, and a shielding member 13. The housing 10 has a receiving space 101 and a plurality of through grooves 102. The plurality of through grooves 102 are arranged at intervals along a first direction X on the inner surface of the housing 10, and the plurality of through grooves 102 communicate with the receiving space 101. Each through groove 102 extends along a second direction Y orthogonal to the first direction X. Both ends of each through groove 102 penetrate through two opposite outer surfaces of the housing 10 in the second direction Y, and the receiving space 101 can communicate with the outside of the electrical connector 1 through the plurality of through grooves 102.

[0016] The housing 10 of this embodiment has a first inner surface 10a and two second inner surfaces 10b. The first inner surface 10a is located between the two second inner surfaces 10b. The first inner surface 10a is in a direction parallel to the first direction X. A plurality of through slots 102 of this embodiment are arranged at intervals on the first inner surface 10a along the first direction X. The two second inner surfaces 10b are oppositely arranged in the first direction X. The housing 10 of this embodiment further has two first outer surfaces 10c, a first end face 10d, and a second end face 10e. The two first outer surfaces 10c are opposite and are in the first direction X. The two first outer surfaces 10c respectively correspond to the two second inner surfaces 10b. The first end face 10d and the second end face 10e are opposite and are in the second direction Y.

[0017] Specifically, please refer to Figure 5 simultaneously, which is a perspective view of the second housing of an embodiment of the present application. As shown in the figure, the housing 10 of this embodiment includes a first housing 100a and a second housing 100b. The first housing 100a has an accommodation space 101. The second housing 100b is disposed on the first housing 100a to form the accommodation space 101. A plurality of through slots 102 are located on the inner surface of the second housing 100b (i.e., the first inner surface 10a). The housing 10 further has a second outer surface 10f and a third outer surface 10g. The second outer surface 10f and the third outer surface 10g are opposite and are in the second direction Y. The second outer surface 10f is close to the first end face 10d of the housing 10, and the second outer surface 10f is close to the second end face 10e of the housing 10. In this embodiment, the second outer surface 10f and the third outer surface 10g are located on the surface of the second housing 100b away from the first housing 100a. Both ends of each through slot 102 penetrate through the second outer surface 10f and the third outer surface 10g respectively. Each through slot 102 forms a first opening 1021 on the first inner surface 10a, each through slot 102 forms a second opening 1022 on the second outer surface 10f, and each through slot 102 forms a third opening 1023 on the third outer surface 10g. The housing 10 of this embodiment is assembled by the first housing 100a and the second housing 100b. If the housing 10 is integrally formed, a plurality of through slots 102 are formed on the first inner surface 10a of the housing 10.

[0018] The circuit board 11 is disposed in the accommodating space 101 and protrudes from the first end face 10d of the housing 10. In an embodiment, the housing 10 has a plugging opening 103 which is formed on the first end face 10d of the housing 10. Specifically, the circuit board 11 has a connecting end 11a and a plugging end 11b. The connecting end 11a of the circuit board 11 is located in the accommodating space 101, and the plugging end 11b of the circuit board 11 is located outside the first end face 10d of the housing 10. The cable 12 penetrates into the accommodating space 101 from the second end face 10e of the housing 10, and the cable 12 located in the accommodating space 101 is connected to the connecting end 11a of the circuit board 11. In an embodiment, the second end face 10e of the housing 10 has a wiring hole 104 which is communicated with the accommodating space 101. One end of the cable 12 connected to the circuit board 11 enters the accommodating space 101 through the wiring hole 104. Specifically, the wiring hole 104 is formed on the first housing 100a and the second housing 100b, that is, the first housing 100a has a first wiring notch 104a, and the second housing 100b also has a second wiring notch 104b. The first wiring notch 104a of the first housing 100a is connected to the second wiring notch 104b of the second housing 100b to form the wiring hole 104.

[0019] The shielding member 13 is disposed in the accommodating space 101 and covers the plurality of through grooves 102 to separate the accommodating space 101 and the plurality of through grooves 102. In this way, the shielding member 13 blocks the communication between the plurality of through grooves 102 and the accommodating space 101, and also blocks the communication between the accommodating space 101 and the outside of the electrical connector 1. Specifically, the shielding member 13 of this embodiment is disposed on the first inner surface 10a of the housing 10, and the shielding member 13 closes the plurality of first openings 1021 formed by the plurality of through grooves 102 on the first inner surface 10a of the housing 10 to block the communication between the plurality of through grooves 102 and the accommodating space 101. The outside of the electrical connector 1 is communicated with the plurality of through grooves 102, but is blocked by the shielding member 13 and is not communicated with the accommodating space 101. In other words, the external air flow of the electrical connector 1 can enter the corresponding through groove 102 from the plurality of second openings 1022 (or the plurality of third openings 1023) and flow out from the plurality of third openings 1023 (or the plurality of second openings 1022). Both sides of the shielding member 13 of this embodiment respectively abut against the two second inner surfaces 10b to ensure that there is no gap between the shielding member 13 and the two second inner surfaces 10b, and block the communication between the accommodating space 101 and the outside of the electrical connector 1.

[0020] When the electrical connector 1 is plugged into the docking connector, the shielding member 13 can prevent electromagnetic interference generated during signal transmission by the circuit board 11 and the cable 12. In other words, the shielding member 13 closes the plurality of through slots 102, effectively preventing the electromagnetic generated during signal transmission by the circuit board 11 and the cable 12 from leaking out of the electrical connector 1 in large amounts through the plurality of through slots 102, and at the same time preventing external electromagnetic from entering the accommodating space 101 through the plurality of through slots 102 and affecting the operation of the circuit board 11 and the cable 12. Therefore, the shielding member 13 of this embodiment realizes the function of electromagnetic shielding, effectively reducing the problem of crosstalk occurring during signal transmission of the electrical connector 1, and enabling the electrical connector 1 to have good signal transmission performance.

[0021] In addition, if the shielding member 13 is made of a material with better heat conduction effect, such as metal, it can also have the effect of concentrating heat energy. When the electrical connector 1 is in use, the heat energy generated by the circuit board 11 and the cable 12 can be concentrated on the shielding member 13. A fan or other air extraction device can be provided outside the electrical connector 1. The fan or air extraction device can disturb the air flow outside the electrical connector 1, that is, make the air flow outside the electrical connector 1 in a flowing state. The air flow outside the electrical connector 1 can enter the corresponding through slot 102 from the second opening 1022 (or the third opening 1023). The air flow entering the through slot 102 takes away the heat energy on the shielding member 13 and flows out from the third opening 1023 (or the second opening 1022) to improve the heat dissipation effect of the electrical connector 1.

[0022] The shielding member 13 of this embodiment can be movably arranged on the housing 10. Therefore, the material of the shielding member 13 can be different from or the same as the material of the housing 10. The materials of the housing 10 and the shielding member 13 can be selected according to the required performance of the electrical connector 1. When the electrical connector 1 is required to have good electromagnetic shielding effect and good heat dissipation effect, the materials of the housing 10 and the shielding member 13 can use materials that can have both electromagnetic shielding effect and heat conduction effect; or the material of the housing 10 can use a material with good heat conduction effect, and the material of the shielding member 13 can use a material that can have good electromagnetic shielding effect. When the electrical connector 1 emphasizes the role of electromagnetic shielding, the material of the shielding member 13 can use a material with good electromagnetic shielding effect, such as conductive plastic or electroplated plastic, and the material of the housing 10 can use a material that has both electromagnetic shielding effect and heat conduction effect, especially a material with better electromagnetic shielding effect than heat conduction effect. When the electrical connector 1 emphasizes the heat dissipation function, the material of the shielding member 13 can use a material with good heat conduction effect, such as metal, and the material of the housing 10 can use a material that has both electromagnetic shielding effect and heat conduction effect, especially a material with better heat conduction effect than electromagnetic shielding effect.

[0023] As described above, since the shielding member 13 and the housing 10 are separately provided, the materials of the housing 10 and the shielding member 13 can be respectively selected as appropriate according to the required performance of the electrical connector 1, so as to ensure that the electrical connector 1 can achieve the preset performance and meet the user's requirements. At the same time, the separate manufacturing of the shielding member 13 and the housing 10 can simplify the manufacturing and save costs.

[0024] In an embodiment, the housing 10 further has a receiving notch 105. The receiving notch 105 is located on the first inner surface 10a having a plurality of through grooves 102. The receiving notch 105 communicates with the plurality of through grooves 102, and the receiving notch 105 is closer to the receiving space 101 than the plurality of through grooves 102. Specifically, the receiving notch 105 is provided on the first inner surface 10a of the second housing 100b. When the shielding member 13 is not yet disposed in the housing 10, the receiving space 101 communicates with the plurality of through grooves 102 through the receiving notch 105. When the shielding member 13 is disposed in the housing 10, the shielding member 13 is disposed in the receiving notch 105, and the shielding member 13 abuts against the spaced side walls between two adjacent through grooves 102, so that the plurality of through grooves 102 do not communicate with each other, that is, each through groove 102 forms an independent channel.

[0025] In this embodiment, the receiving notch 105 has engaging notches 1052 on two opposite side walls 1051 in the second direction Y. The shielding member 13 of this embodiment has a shielding plate body 131, and opposite ends of the shielding plate body 131 respectively have engaging protrusions 1311. When the shielding member 13 is disposed in the housing 10, the engaging protrusions 1311 of the shielding member 13 are respectively disposed in the corresponding engaging notches 1052 to fix the shielding member 13 in the housing 10. Specifically, the side wall 1051 of the receiving notch 105 corresponding to the second outer surface 10f has a plurality of engaging notches 1052 arranged at intervals, and the plurality of engaging notches 1052 respectively correspond to the plurality of second openings 1022. The side wall 1051 of the receiving notch 105 corresponding to the third outer surface 10g has a plurality of engaging notches 1052 arranged at intervals, and the plurality of engaging notches 1052 respectively correspond to the plurality of third openings 1023. One end of the shielding plate body 131 close to the first end face 10d has a plurality of engaging protrusions 1311 arranged at intervals, and one end of the shielding plate body 131 close to the second end face 10e has a plurality of engaging protrusions 1311 arranged at intervals. The plurality of engaging protrusions 1311 respectively cooperate with the corresponding engaging notches 1052 to fix the shielding member 13 in the housing 10. In an embodiment, the shielding plate body 131 has a positioning hole 1312, and the second housing 100b has a positioning post 106. The positioning post 106 is disposed on the spaced side wall between two adjacent through grooves 102. When the shielding member 13 is disposed in the housing 10, the positioning post 106 passes through the positioning hole 1312 to position the shielding member 13 in the housing 10.

[0026] In one embodiment, the electrical connector 1 further includes a heat-conducting member 14. The heat-conducting member 14 is disposed between the cable 12 and the shielding member 13, and the heat-conducting member 14 covers one end of the cable 12 connected to the circuit board 11. In this way, the heat-conducting member 14 can quickly guide the heat energy generated by the circuit board 11 and the cable 12 to the shielding member 13, accelerating the speed at which the shielding member 13 concentrates the heat energy, and further improving the heat dissipation effect of the electrical connector 1. The material of the heat-conducting member 14 in this embodiment is heat-conducting silicone. Of course, the material of the heat-conducting member 14 can also be other heat-conducting materials, and should not be limited thereto.

[0027] The shielding member 13 in this embodiment further has a plurality of limiting pieces 132, and the plurality of limiting pieces 132 are respectively disposed on opposite sides of the shielding plate body 131. When the shielding member 13 is disposed in the housing 10, the plurality of limiting pieces 132 extend into the accommodating space 101, that is, extend in a direction away from the first inner surface 10a. The plurality of limiting pieces 132 are located on both sides of the heat-conducting member 14, the cable 12, and the circuit board 11 to limit the heat-conducting member 14 between the shielding plate body 131 and the cable 12. The housing 10 in this embodiment has support protrusions 107 on the first direction X and two opposite second inner surfaces 10b respectively. When the shielding member 13 is disposed in the housing 10, one ends of the plurality of limiting pieces 132 away from the shielding plate body 131 respectively abut against the corresponding support protrusions 107, and the shielding member 13 is supported by the support protrusions 107, so that the shielding plate body 131 is adjacent to the plurality of spaced side walls between the plurality of through grooves 102 to fix the shielding member 13 in the housing 10.

[0028] The circuit board 11 in this embodiment has a plurality of conductive pads 111 and a plurality of contact pads 112. The plurality of conductive pads 111 are arranged at intervals at the connection end 11a of the circuit board 11, the plurality of contact pads 112 are arranged at intervals at the insertion end 11b of the circuit board 11, and the plurality of conductive pads 111 and the plurality of contact pads 112 are connected by a plurality of lines. The cable 12 has a plurality of wires 121, and the plurality of wires 121 are respectively connected to the corresponding conductive pads 111.

[0029] In one embodiment, the electrical connector 1 further includes a latch assembly 15. The latch assembly 15 is movably disposed on the housing 10. When the electrical connector 1 is plugged into the docking connector, the latch assembly 15 is latched with the docking connector, fixing the electrical connector 1 in the docking connector. When the electrical connector 1 is to be disengaged from the docking connector, the latching state between the latch assembly 15 and the docking connector is released by pulling the latch assembly 15, allowing the electrical connector 1 to be disengaged from the docking connector. The latch assembly 15 of this embodiment includes two latch spring pieces 151 and an unlocking handle 152. The two latch spring pieces 151 are symmetrically arranged, and the unlocking handle 152 is connected to the two latch spring pieces 151 respectively. Each end of the latch spring piece 151 away from the unlocking handle 152 has a latching recess 1511. Each of the two first outer surfaces 10c of the housing 10 orthogonal to the first direction X has a receiving groove 108. Each receiving groove 108 extends in the second direction Y, and one end of each receiving groove 108 penetrates the second end surface 10e of the housing 10. Specifically, the two latch spring pieces 151 are respectively movably disposed in the corresponding receiving grooves 108, and the latching recess 1511 is recessed toward the accommodation space 101 of the housing 10, and the unlocking handle 152 extends from the second end surface 10e of the housing 10 in a direction away from the housing 10. The receiving groove 108 of this embodiment has a recessed portion 1080 located between the first end surface 10d and the second end surface 10e. The latching recess 1511 of the latch spring piece 151 is located in the recessed portion 1080, enabling the latch spring piece 151 to be close to the surface of the receiving groove 108 in the first direction X. When the electrical connector 1 is plugged into the docking connector, the latching spring piece of the docking connector enters the latching recess 1511 of the latch spring piece 151.

[0030] When the electrical connector 1 is to be disengaged from the docking connector, by pulling the unlocking handle 152, the two latch spring pieces 151 are driven to move in a direction away from the first end surface 10d of the housing 10, causing the latching spring piece of the docking connector to disengage from the latching recess 1511 of the corresponding latch spring piece 151, so as to release the latching state between each latch spring piece 151 and the docking connector, and further enabling the electrical connector 1 to be disengaged from the docking connector. The receiving groove 108 of this embodiment is provided on the first housing 100a and the second housing 100b. Each side of the first housing 100a has a lower receiving groove 108a, and each side of the second housing 100b has an upper receiving groove 108b. When the second housing 100b is disposed on the first housing 100a, each upper receiving groove 108b is joined with the corresponding lower receiving groove 108a to form the receiving groove 108.

[0031] In one embodiment, please also refer to Figure 6, is a partial perspective view of an electrical connector according to an embodiment of the present application; as shown in the figure, each receiving groove 108 further has an unlocking groove 1081 on the surface in the first direction X, and each unlocking groove 1081 extends along the second direction Y. The unlocking groove 1081 of this embodiment is located on the first housing 100a. One side of each locking spring piece 151 has an unlocking protrusion 1512, and the unlocking protrusion 1512 is located between the buckling recess 1511 and the unlocking handle 152. When each locking spring piece 151 is movably disposed in the corresponding receiving groove 108, the unlocking protrusion 1512 extends into the unlocking groove 1081, and each locking spring piece 151 moves in the receiving groove 108, and the unlocking protrusion 1512 also moves in the unlocking groove 1081, which also means that the width of the unlocking protrusion 1512 in the second direction Y is smaller than the width of the unlocking groove 1081 in the second direction Y, so that the unlocking protrusion 1512 can move in the unlocking groove 1081. The electrical connector 1 of this embodiment further includes two elastic members 16, and the two elastic members 16 are respectively disposed in the corresponding unlocking grooves 1081. Each elastic member 16 extends along the second direction Y. One end of each elastic member 16 abuts against the unlocking protrusion 1512, and the other end of each elastic member 16 abuts against the second end surface 10e of the unlocking groove 1081 close to the housing 10 and on the surface in the second direction Y, that is, abuts against the surface of the unlocking groove 1081 away from the unlocking protrusion 1512. When the unlocking handle 152 pulls the locking spring piece 151 to move in a direction away from the first end surface 10d of the housing 10, the unlocking protrusion 1512 compresses the elastic member 16. When the unlocking handle 152 stops pulling the locking spring piece 151, the elastic force of the compressed elastic member 16 pushes the unlocking protrusion 1512 to move in a direction close to the first end surface 10d of the housing 10, thereby driving the locking spring piece 151 to move in a direction close to the first end surface 10d of the housing 10, so that the locking assembly 15 returns to the state where it is not pulled.

[0032] In one embodiment, each receiving groove 108 further has a limiting groove 1082 on two surfaces opposite to each other in a direction orthogonal to the first direction X. The limiting groove 1082 extends along the second direction Y. In this embodiment, each lower receiving groove 108a of the first housing 100a has two limiting grooves 1082, and each upper receiving groove 108b of the second housing 100b has two limiting grooves 1082. The multiple limiting grooves 1082 of the second housing 100b respectively correspond to the multiple limiting grooves 1082 of the first housing 100a. Both sides of each locking elastic piece 151 respectively have a limiting convex portion 1513, and the limiting convex portion 1513 is located between the buckling concave portion 1511 and the unlocking convex portion 1512, that is, the limiting convex portion 1513 is closer to the buckling concave portion 1511 than the unlocking convex portion 1512. When each locking elastic piece 151 is movably arranged in the corresponding receiving groove 108, each limiting convex portion 1513 extends into the corresponding limiting groove 1082. Each locking elastic piece 151 moves in the receiving groove 108, and the limiting convex portion 1513 also moves in the limiting groove 1082, which also means that the width of the limiting convex portion 1513 in the second direction Y is smaller than the width of the limiting groove 1082 in the second direction Y, so that the limiting convex portion 1513 can move in the limiting groove 1082.

[0033] In one embodiment, each receiving groove 108 further has a first stop notch 1083 on a surface in a direction orthogonal to the first direction X and away from the first inner surface 10a. The first stop notch 1083 penetrates the second end surface 10e of the outer shell 10. In this embodiment, the first stop notch 1083 is located on the first housing 100a. One side of each locking elastic piece 151 away from the unlocking convex portion 1512 has a first stop convex portion 1514. The first stop convex portion 1514 is located between the unlocking convex portion 1512 and the unlocking handle 152. The first stop convex portion 1514 of this embodiment is close to the connection part of the locking elastic piece 151 and the unlocking handle 152. When each locking elastic piece 151 is movably arranged in the corresponding receiving groove 108, the first stop convex portion 1514 extends into the corresponding first stop notch 1083. Each locking elastic piece 151 moves in the receiving groove 108, and the first stop convex portion 1514 also moves in the first stop notch 1083. The surface of the first stop notch 1083 in the second direction Y can block the first stop convex portion 1514 from moving towards the direction close to the first end surface 10d of the outer shell 10, so as to position the locking elastic piece 151 in the receiving groove 108. In one embodiment, the first stop notch 1083 of this embodiment further penetrates the lower surface of the outer shell 10. The locking component 15 further includes a strengthening connecting piece 153. Both ends of the strengthening connecting piece 153 are respectively connected to the first stop convex portions 1514 of each locking elastic piece 151. The strengthening connecting piece 153 is located on the lower surface of the outer shell 10. The two locking elastic pieces 151 are connected through the strengthening connecting piece 153 to increase the structural strength of the two locking elastic pieces 151.

[0034] In one embodiment, each receiving groove 108 further has a second stop notch 1084 on the surface in the first direction X. The second stop notch 1084 penetrates through the second end face 10e of the housing 10. In this embodiment, the second stop notch 1084 is located on the first housing 100a. On the side of each locking spring piece 151 having an unlocking convex portion 1512, there is also a second stop convex portion 1515. The second stop convex portion 1515 is opposite to the first stop convex portion 1514. The second stop convex portion 1515 is located between the unlocking convex portion 1512 and the unlocking handle 152. In this embodiment, the second stop convex portion 1515 is close to the connection portion of the locking spring piece 151 and the unlocking handle 152. When each locking spring piece 151 is movably disposed in the corresponding receiving groove 108, the second stop convex portion 1515 extends into the corresponding second stop notch 1084. Each locking spring piece 151 moves in the receiving groove 108, and the second stop convex portion 1515 also moves in the second stop notch 1084. The surface of the second stop notch 1084 in the second direction Y can block the second stop convex portion 1515 from moving towards the first end face 10d of the housing 10, so as to position the locking spring piece 151 in the receiving groove 108.

[0035] In summary, the present application provides an electrical connector. By separating the accommodating space and the plurality of through grooves with a shielding member, it effectively blocks the communication between the accommodating space and the outside of the electrical connector through the plurality of through grooves. The shielding member can achieve the function of electromagnetic shielding, enabling the electrical connector to have good signal transmission performance. If the material of the shielding member can use a material with better heat conduction effect, such as metal, the shielding member also has the function of concentrating heat energy. When the external air flow passes through the plurality of through grooves, it can take away the heat energy concentrated by the shielding member together, effectively improving the heat dissipation effect of the electrical connector, and at the same time enabling the electrical connector to have good signal transmission effect and heat dissipation effect. The shielding member and the housing are separately provided, and appropriate materials can be selected respectively according to the performance to be achieved by the electrical connector, avoiding the electrical connector being unable to achieve the expected performance due to the material selection, and at the same time simplifying the manufacturing of the housing and the shielding member, effectively reducing the overall cost.
