During the process of fixing the connector body to the housing, the connector body is prone to displacement relative to the housing, which means that the connector body is not fixed in the preset fixed position, resulting in poor assembly accuracy of the connector. Summary of the Invention

[0003] This application provides an electrical connector that solves the problem that in current connectors, the connector body is directly fixed in the housing, and the connector body is easily not fixed in the preset fixed position, resulting in poor assembly accuracy of the connector.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is a perspective view, a partially exploded view, and an assembled perspective view of the connector body, cable, and connecting housing according to the first embodiment of this application. Figure 1 Sectional view along line A-A' and Figure 2 A cross-sectional view along line B-B' is shown in the figure. In this embodiment, the electrical connector 1 is an I / O connector, which connects to a chip connector via a cable to achieve high-speed transmission. The electrical connector 1 of this embodiment includes a connector body 10, a cable 11, a connecting housing 12, a limiting member 13, and a shell 14. The connector body 10 has opposing insertion sides 10a and connecting sides 10b. The connector body 10 includes multiple terminals. One end of the cable 11 is connected to at least one of the multiple terminals and exits from the connecting side 10b of the connector body 10. The connecting housing 12 is disposed on the connecting side 10b of the connector body 10. The cable 11 exits from the side of the connecting housing 12 near the connecting side 10b; that is, the surface of the connecting housing 12 near the connecting side 10b has a wiring hole 120, through which the cable 11 passes to exit from the side of the connecting housing 12 near the connecting side 10b. A limiting member 13 is disposed on the side of the connecting housing 12 near the insertion side 10a, and a housing 14 is disposed on the side of the connecting housing 12 near the insertion side 10a. The connecting housing 12 is located on the side wall of the housing 14 in the first direction X and protrudes from the side wall of the housing 14 in the first direction X in a direction away from the housing 14. The insertion side 10a of the connector body 10 is located inside the housing 14. The limiting member 13 corresponds to the side wall of the housing 14 in the first direction X to prevent the connecting housing 12 from detaching from the housing 14 along the first direction X. Specifically, the housing 14 has a first side wall 14a, a second side wall 14b, and two third side walls 14c. The second side wall 14b is disposed on the side of the first side wall 14a in the first direction X, and the two third side walls 14c are respectively disposed on the two sides of the first side wall 14a in the second direction Y. The second side wall 14b and the two third side walls 14c all extend along the third direction Z. The second sidewall 14b is connected to two third sidewalls 14c, and the second sidewall 14b is located between the two third sidewalls 14c. The second sidewall 14b is the sidewall of the outer shell 14 in the first direction X, that is, the connecting shell 12 is disposed on the second sidewall 14b and protrudes from the second sidewall 14b in a direction away from the outer shell 14. The second sidewall 14b has an assembly notch 141, which extends from the side of the second sidewall 14b away from the first sidewall 14a to the side where the second sidewall 14b is connected to the first sidewall 14a. The connecting shell 12 is inserted into the assembly notch 141, and the limiting member 13 corresponds to the second sidewall 14b to limit the displacement of the connecting shell 12 in the first direction X.

[0024] The limiting member 13 is disposed on the side of the connecting housing 12 near the assembly notch 141, corresponding to the second sidewall 14b of the outer shell 14. Specifically, the limiting member 13 includes a first limiting piece 131, two second limiting pieces 132, and a limiting protrusion 133, for ease of subsequent explanation. The first limiting piece 131 is disposed on the side of the surface of the connecting housing 12 near the first sidewall 14a and extends towards the first sidewall 14a along a third direction Z. In this embodiment, the first limiting piece 131 is disposed on the side edge of the surface of the connecting housing 12 near the first sidewall 14a. The two second limiting pieces 132 are respectively disposed on the side of the surface of the connecting housing 12 near the corresponding third sidewall 14c and extend towards the corresponding third sidewall 14c along a second direction Y. In this embodiment, the two second limiting pieces 132 are respectively disposed on the side edge of the surface of the connecting housing 12 near the corresponding third sidewall 14c. Two limiting protrusions 133 are respectively disposed on the surface of the connecting housing 12 near the corresponding third sidewall 14c, and protrude towards the corresponding third sidewall 14c along the second direction Y. Each limiting protrusion 133 is opposite to the corresponding second limiting piece 132. When the connecting housing 12 is disposed in the assembly notch 141, the first limiting piece 131 and the two second limiting pieces 132 are located inside the outer shell 14, and the first limiting piece 131 and the two second limiting pieces 132 are respectively corresponding to the inner surface of the second sidewall 14b, thus restricting the movement of the connecting housing 12 along the first direction X towards the outer surface of the second sidewall 14b of the outer shell 14. The two limiting protrusions 133 are located outside the outer shell 14 and are respectively corresponding to the outer surface of the second sidewall 14b, thus restricting the movement of the connecting housing 12 along the first direction X towards the inner surface of the second sidewall 14b of the outer shell 14.

[0025] Please refer to the following: Figure 7 and Figure 8 ,yes Figure 2 Enlarged view of region A in the middle and Figure 3Enlarged view of region B in the figure; as shown, the limiting protrusion 133 of this embodiment has a limiting end 133a and a guiding end 133b. The limiting end 133a is parallel to the side of the surface of the connecting housing 12 near the corresponding third side wall 14c, that is, parallel to the third direction Z. The guiding end 133b is inclined relative to the side of the surface of the connecting housing 12 near the corresponding third side wall 14c, that is, inclined relative to the third direction Z. The minimum distance D1 from the end of the guiding end 133b away from the limiting end 133a to the corresponding second limiting piece 132 (the side of the connecting housing 12 near the third side wall 14c) is greater than the minimum distance D2 from the end of the guiding end 133b near the limiting end 133a to the corresponding second limiting piece 132 (the side of the connecting housing 12 near the third side wall 14c). When the connecting housing 12 is positioned at the assembly notch 141, the second sidewall 14b of the housing 14 first passes through the guide end 133b and then enters the limiting end 133a. The guide end 133b guides the second sidewall 14b of the housing 14 into the space between the second limiting piece 132 and the limiting end 133a. Therefore, the guide end 133b is closer to the first sidewall 14a than the limiting end 133a. Simultaneously, the minimum distance D2 from the limiting end 133a to the corresponding second limiting piece 132 (the side of the connecting housing 12 near the third sidewall 14c) is slightly greater than or equal to the thickness of the second sidewall 14b (e.g., ...). Figure 6 As shown), to restrict the connecting housing 12 on the outer shell 14. In this embodiment, the limiting member 13 is integrated with the connecting housing 12. The first limiting piece 131 and two second limiting pieces 132 are formed by stamping and bending, and the two limiting protrusions 133 are formed by stamping. In this embodiment, the limiting protrusions 133 are hollow.

[0026] See also Figure 2 , Figure 4 and Figure 5 In this embodiment, the first limiting piece 131 has a limiting portion 131a and a positioning portion 131b. The limiting portion 131a is closer to the connecting housing 12 than the positioning portion 131b. In this embodiment, the first sidewall 14a of the outer shell 14 has a positioning hole 142. When the connecting housing 12 is disposed in the assembly notch 141, the positioning portion 131b is disposed in the positioning hole 142 to position the connecting housing 12 in the outer shell 14. The limiting portion 131a corresponds to the inner surface of the second sidewall 14b to restrict the connecting housing 12 from moving along the first direction X and toward the outer surface of the second sidewall 14b. In this embodiment, the width of the positioning portion 131b in the second direction Y is smaller than the width of the limiting portion 131a in the second direction Y.

[0027] In other embodiments, a plurality of first limiting pieces 131 may be provided on the side of the connecting housing 12 near the first side wall 14a, and a plurality of second limiting pieces 132 may be provided on the side of the connecting housing 12 near the corresponding third side wall 14c, which can also achieve the function of limiting.

[0028] In other embodiments, the limiting member 13 may include only at least one of the first limiting piece 131, the second limiting piece 132, and the limiting protrusion 133. For example, the limiting member 13 may include the first limiting piece 131, two second limiting pieces 132, or two limiting protrusions 133. Alternatively, the limiting member 13 may include the first limiting piece 131 and two second limiting pieces 132, two second limiting pieces 132 and two limiting protrusions 133, or the first limiting piece 131 and two limiting protrusions 133.

In one embodiment, a plurality of positioning posts 1012 are provided on the surface of the insulating body 101 away from the outer shell 14, and the base plate 16 has a plurality of positioning holes 161. When the base plate 16 is disposed on the side of the insulating body 101 away from the outer shell 14, each positioning post 1012 passes through the corresponding positioning hole 161 to position the base plate 16 on the connector body 10.

After the fixing posts 1013 pass through the corresponding fixing holes 163, one end of the fixing posts 1013 located outside the base plate 16 is heated to melt one end of the fixing posts 1013 located outside the base plate 16. The molten fixing posts 1013 cover the inner grooves 162 around the fixing holes 163, so that the base plate 16 is fixed to the connector body 10.

[0033] See also Figure 2 , Figure 3 and Figure 6The electrical connector 1 in this embodiment further includes a heat dissipation assembly 17, which is disposed on the outer surface of the first sidewall 14a of the housing 14. The heat dissipation assembly 17 includes a plurality of heat sinks 171, which are spaced apart along the second direction Y on the outer surface of the first sidewall 14a of the housing 14 and correspond to a plurality of receiving spaces 143 respectively, so as to dissipate heat from the mating connectors inserted into the corresponding receiving spaces 143.

The fixing spring 18 simultaneously presses against the plurality of heat sinks 171 to fix the plurality of heat sinks 171 to the housing 14.

[0034] See also Figure 2 , Figure 4 and Figure 5The electrical connector 1 in this embodiment also includes a light guide tube 19. The light guide tube 19 has an input end 19a and an output end 19b. The input end 19a of the light guide tube 19 is located on the side of the connecting housing 12 away from the outer shell 14, and the output end 19b of the light guide tube 19 is located on one side of the outer shell 14. The light guide tube 19 can guide the light emitted by the light-emitting element of the circuit board. Specifically, the light guide tube 19 has a first light-guiding end 191 and a second light-guiding end 192 connected to each other. The first light-guiding end 191 extends along a third direction Z, and the second light-guiding end 192 extends along a first direction X, thus forming an L-shaped light guide tube 19. The input end 19a is located at the end of the first light-guiding end 191 away from the second light-guiding end 192, and the output end 19b is located at the end of the second light-guiding end 192 away from the first light-guiding end 191.

The outer surface of the first sidewall 14a of the outer shell 14 also has a second positioning tab 145 that extends along the third direction Z. When the connecting housing 12 is disposed on the outer shell 14, the first positioning protrusion 123 is located outside the outer shell 14 and has a gap between it and the second sidewall 14b of the outer shell 14. When the light guide tube 19 is disposed on the outer shell 14, the first positioning protrusion 193 is connected to the first positioning protrusion 123, and the second positioning protrusion 194 is connected to the second positioning protrusion 145 to fix the light guide tube 19 on the connecting housing 12 and the outer shell 14. In this embodiment, the end of the first positioning protrusion 193 away from the first light guide end 191 has a first latching portion 1931, and the first positioning protrusion 123 has a first positioning through hole 1231. When the first latching portion 1931 passes through the first positioning through hole 1231, the first latching portion 1931 abuts against the surface of the first positioning through hole 1231 near the second sidewall 14b to fix the light guide tube 19 on the connecting housing 12.

[0035] The structure of the connector body 10 in this embodiment is described in detail below. Please refer to the following text for further details. Figure 9 and Figure 10 ,yes Figure 4 Exploded diagram and Figure 9 An enlarged view of region C is shown in the figure. The connector body 10 includes a first terminal assembly 102a and a second terminal assembly 102b, with the first terminal assembly 102a disposed on one side of the second terminal assembly 102b. Both the first terminal assembly 102a and the second terminal assembly 102b include multiple terminals 1021. The connector body 10 of this embodiment also includes an adapter plate 103, disposed between the first terminal assembly 102a and the second terminal assembly 102b. The surface of the adapter plate 103 near the first terminal assembly 102a has multiple terminal conductive pads 1031 and multiple cable conductive pads 1032. The multiple terminal conductive pads 1031 are arranged in a row at intervals on one side of the adapter plate 103, and the multiple cable conductive pads 1032 are arranged in a row at intervals on the other side of the adapter plate 103. Each terminal conductive pad 1031 is connected to a corresponding terminal 1021 in the first terminal assembly 102a. There are multiple cables 11, each cable 11 having at least one signal line 11a and at least one ground line 11b. Each signal line 11a of each cable 11 is connected to a corresponding cable conductive pad 1032, and each ground line 11b of each cable 11 is connected to a corresponding cable conductive pad 1032. An insulating body 101 is disposed on the first terminal assembly 102a, the second terminal assembly 102b, the adapter plate 103, and the multiple cables 11.

[0036] In this embodiment, the multiple terminals 1021 of the first terminal assembly 102a include multiple ground terminals 1021a, multiple signal terminals 1021b, and multiple power terminals 1021c. In this embodiment, there are four ground terminals 1021a, four signal terminals 1021b, and two power terminals 1021c. Two signal terminals 1021b are disposed between two adjacent ground terminals 1021a, and two power terminals 1021c are disposed adjacent to each other. Two adjacent power terminals 1021c form a power terminal group. Ground terminals 1021a are located on both sides of each power terminal group; that is, two adjacent power terminals 1021c (power terminal groups) are disposed between two adjacent ground terminals 1021a. Figure 10As can be seen from the diagram, the arrangement of the multiple terminals 1021 of the first terminal assembly 102a from right to left is: ground terminal 1021a, two signal terminals 1021b, ground terminal 1021a, two power terminals 1021c, ground terminal 1021a, two signal terminals 1021b, and ground terminal 1021a again. The multiple ground terminals 1021a and multiple signal terminals 1021b are respectively connected to the corresponding terminal conductive pads 1031. Please refer to the attached diagram. Figure 11 ,yes Figure 5 An enlarged view of region D is shown; as illustrated, one end of each of the two power terminals 1021c and the plurality of terminals 1021 of the second terminal assembly 102b protrudes from one side of the insulating body 101 to connect to an external circuit board. In this embodiment, the plurality of signal terminals 1021b of the first terminal assembly 102a are high-speed terminals, connected to a plurality of cables 11 via an adapter plate 103, and connected to an external chip connector via the plurality of cables 11, thus achieving high-speed transmission while ensuring the robustness of the connections between the plurality of ground terminals 1021a and the plurality of signal terminals 1021b and the plurality of cables 11.

[0037] Each terminal 1021 in this embodiment has a contact end 10211 and a connection end 10212. The connection end 10212 of each ground terminal 1021a and the connection end 10212 of each signal terminal 1021b of the first terminal assembly 102a are respectively connected to the corresponding terminal conductive pad 1031. The width of the connection end 10212 of each ground terminal 1021a in this embodiment is smaller than the contact end 10211 of each ground terminal 1021a and smaller than the width of the terminal conductive pad 1031, ensuring that the connection end 10212 of each ground terminal 1021a can be located in the terminal conductive pad 1031, increasing the contact area between the connection end 10212 of each ground terminal 1021a and the terminal conductive pad 1031, so that the connection end 10212 of each ground terminal 1021a can be stably connected to the corresponding terminal conductive pad 1031. Similarly, in this embodiment, the width of the connection end 10212 of each signal terminal 1021b is smaller than the contact end 10211 of each signal terminal 1021b and smaller than the width of the terminal conductive pad 1031, ensuring that the connection end 10212 of each signal terminal 1021b can be located in the terminal conductive pad 1031, increasing the contact area between the connection end 10212 of each signal terminal 1021b and the terminal conductive pad 1031, so that the connection end 10212 of each signal terminal 1021b can be stably connected to the corresponding terminal conductive pad 1031. Of course, the wire diameter of each signal line 11a and each ground line 11b of each cable 11 is also smaller than the width of the cable conductive pad 1032, ensuring that each signal line 11a and each ground line 11b can be located in the cable conductive pad 1032, increasing the contact area between each signal line 11a and each ground line 11b and the corresponding cable conductive pad 1032, so that each signal line 11a and each ground line 11b are firmly connected to the corresponding cable conductive pad 1032. In addition, in this embodiment, the multiple signal lines 11a and multiple ground lines 11b of each cable 11 are not directly soldered to the multiple signal terminals 1021b and multiple ground terminals 1021a. In this way, the wire diameter of each signal line 11a and each ground line 11b of each cable 11 is not limited by the size of the terminal 1021, improving the selectivity of the wire diameter of each signal line 11a and each ground line 11b of each cable 11, reducing the complexity of the soldering process, and also reducing the overall soldering cost.

[0038] The connecting end 10212 of each power terminal 1021c of the first terminal assembly 102a is orthogonal to the contact end 10211. The adapter plate 103 has a clearance notch 1033 through which the connecting end 10212 of each power terminal 1021c passes to protrude from one side of the insulating body 101. The extending direction of the connecting end 10212 of each terminal 1021 of the second terminal assembly 102b is orthogonal to the extending direction of the contact end 10211, and the connecting end 10212 of each terminal 1021 protrudes from one side of the insulating body 101. In this embodiment, the connection end 10212 of each power terminal 1021c of the first terminal assembly 102a and the connection end 10212 of each terminal 1021 of the second terminal assembly 102b respectively have a fisheye structure for insertion into an external circuit board. Of course, the connection end 10212 of each power terminal 1021c of the first terminal assembly 102a and the connection end 10212 of each terminal 1021 of the second terminal assembly 102b can be directly soldered onto an external circuit board.

[0039] In this embodiment, the first terminal assembly 102a and the second terminal assembly 102b further include terminal insulating bodies 1022. The terminal insulating bodies 1022 of the first terminal assembly 102a are disposed on a plurality of terminals 1021 of the first terminal assembly 102a, and the terminal insulating bodies 1022 of the second terminal assembly 102b are disposed on a plurality of terminals 1021 of the second terminal assembly 102b. In this way, the multiple terminals 1021 are integrated by means of the terminal insulating bodies 1022 to facilitate assembly.

[0040] The insulating body 101 in this embodiment includes an insulating shell 1014 and an insulating cover 1015. The insulating shell 1014 has a plug-in groove 10141, and the contact end 10211 of each terminal 1021 is disposed in the plug-in groove 10141. The insulating cover 1015 is connected to the insulating shell 1014 and covers multiple terminal insulating bodies 1022, the connection end 10212 of each terminal 1021, the adapter plate 103, and part of the cable 11. The connecting shell 12 is disposed on the insulating cover 1015, and the base plate 16 is disposed on the insulating shell 1014.

As shown in the figure, when the electrical connector 1 of this embodiment is connected to the mating connector, the mating connector has a plate-shaped member 2, and the two opposing surfaces of the plate-shaped member 2 each have a plurality of contact pads 21 spaced apart. The plate-shaped member 2 is inserted into the insertion slot 10141 of the connector body 10, and the contact end 10211 of each terminal 1021 is connected to the corresponding contact pad 21.

[0042] Please see Figure 13 and Figure 14 Figure 1 is a perspective view and an exploded view of the electrical connector of the second embodiment of this application. As shown in the figure, the electrical connector 1 of this embodiment differs from the electrical connector of the first embodiment in that the connector body 10 of this embodiment does not have an adapter plate. Each signal line 11a of each cable 11 is soldered to the connection end 10212 of the corresponding signal terminal 1021b in the first terminal assembly 102a, and each ground line 11b of each cable 11 is soldered to the connection end 10212 of the corresponding ground terminal 1021a in the first terminal assembly 102a.

[0043] In summary, this application provides an electrical connector.
