[0051] In the process of medical diagnosis and treatment, it is necessary to electrically or signal interconnect multiple medical devices with different functions to achieve joint monitoring, such as electrocardiogram monitors, ultrasound probes, ventilators and infusion pumps. The traditional solution adopts a one-to-one connector design, that is, each device is equipped with a dedicated connector, which only provides one plug interface. When multiple devices need to be connected at the same time, multiple connectors must be arranged side by side on the circuit board, which significantly increases the PCB area occupied and also increases the overall size of the connectors.

[0052] This utility model proposes a socket connector, a plug connector, and a connector assembly.

[0053] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the socket connector 10 includes:

[0054] Housing 110, housing 110 is provided with a plug-in slot;

[0055] Multiple female terminal modules 120 are provided, and the multiple female terminal modules 120 are arranged side by side in the insertion slot. Each female terminal module 120 includes a female end shielding shell 121, a female end insulating body 123 disposed in the female end shielding shell 121, and a female terminal body 122 disposed in the female end insulating body 123. The female end shielding shell 121 is provided with an insertion interface 1210, and the female end insulating body 123 has a mating cavity 1230 exposed at the insertion interface 1210. One end of the female terminal body 122 is soldered to the circuit board, and the other end is exposed in the mating cavity 1230 for insertion with the male terminal body 232. The inner wall of the insertion slot and the female end shielding shell 121 are spaced apart to form an insertion space 111, which is used to insert the insertion part 220 of the plug connector 20.

[0056] In the technical solution of this utility model, the outer shell 110 has an open insertion slot, and multiple female terminal modules 120 are arranged side by side in the insertion slot. Each female terminal module 120 has the same structure, including a female end shielding shell 121, a female terminal body 122, and a female end insulating body 123. The female end shielding shell 121 is sleeved on the outside of the female end insulating body 123. Each female end shielding shell 121 has a plug interface 1210. An insertion space 111 is formed between the outer wall of the female end shielding shell 121 and the inner wall of the insertion slot. The insertion space 111 is used for the plug connector 20 to be inserted. When the plug connector 20 is inserted, the insertion part 220 of the plug connector 20 is inserted into the insertion space 111. The setting of the insertion space 111 makes the connection between the plug connector 20 and the socket connector 10 more stable. To prevent easy detachment, a mating cavity 1230 is formed at the end of the female insulating body 123 near the plug interface 1210. The female terminal body 122 is exposed in the mating cavity 1230. That is, the female insulating body 123 is used to fix the female terminal body 122. The male terminal body 232 of the plug connector 20 is inserted into the mating cavity 1230 so that the male terminal body 232 and the female terminal body 122 are electrically connected. With only one socket connector 10, multiple plug connectors 20 can be connected, and multiple devices can be connected at the same time, reducing the size occupied by the connector. In addition, the female shielding shell 121 is made of metal. Adjacent female terminal bodies 122 are separated by the female shielding shell 121, which can avoid electromagnetic interference between multiple sets of female terminal bodies 122 and ensure signal transmission quality.

[0057] Specifically, the outer casing 110 is made of metal, which is not limited here. The outer casing 110 has an open insertion slot, and one end of the outer casing 110 is fixed to the circuit board. Multiple female terminal modules 120 are arranged side by side in the insertion slot. The multiple female terminal modules 120 can be spaced apart horizontally or vertically from top to bottom, which is not limited here. In this embodiment, two female terminal modules 120 are arranged from top to bottom in the insertion slot. Each female terminal module 120 includes a female terminal shielding shell 121, a female terminal body 122, and a female terminal insulating body 123. The female terminal insulating body 123 is made of plastic and is produced using injection molding. Please refer to [reference needed]. Figure 5 and Figure 6The female end insulating body 123 is provided with a mating cavity 1230 communicating with the plug interface 1210. The female terminal body 122 includes a plurality of terminals. A plurality of terminal slots are provided on the upper and lower sides of the mating cavity 1230 of the female end insulating body 123. Each terminal slot is provided with a terminal. One end of the terminal extends away from the plug interface 1210 and is soldered to the pad of the circuit board. The other end is exposed in the mating cavity 1230. When the plug connector 20 and the socket connector 10 are plugged in, the terminals on the upper and lower sides of the mating cavity 1230 are used to contact and conduct with the male terminal body 232 of the plug connector 20. The female end insulating body 123 is disposed in the female end shielding shell 121 and fits against the female end shielding shell 121 to facilitate the bearing of the stress generated by the plug connector 20 being plugged in and unplugged. The end of the female shield 121 away from the plug interface 1210 is also soldered to the circuit board. In this embodiment, the two sets of female terminal bodies 122 are separated by the female shield 121 to reduce electromagnetic interference between the female terminal bodies 122. The socket connector 10 has two sets of female terminal modules 120, which means it has two plug interfaces 1210, which can be adapted to two sets of plug connectors 20, corresponding to two devices respectively. It can be understood that the socket connector 10 is installed on one device, and the socket connector 10 can be inserted into two devices corresponding to two different plug connectors 20, that is, to realize one device to connect two devices at the same time. Alternatively, the socket connector 10 can be paired with a plug connector 20 with two male terminal modules 230. The circuit boards connected to the two male terminal modules 230 of the plug connector 20 are two devices respectively, which also realizes one device to connect two devices at the same time, reducing the space occupied by the connector.

[0058] In an embodiment of this utility model, the socket connector 10 further includes a female end mounting body 130. The female end mounting body 130 has insertion cavities 131 arranged side by side and spaced apart. Each female terminal module 120 is correspondingly disposed in a insertion cavity 131. The female end mounting body 130 is disposed in the insertion groove, and an insertion space 111 is formed between the inner wall of the insertion groove and the outer wall of the female end mounting body 130.

[0059] Please refer to Figure 2 and Figure 7The female mounting body 130 is made of plastic injection molding. The female mounting body 130 is set in the insertion slot. The gap between the outer wall of the female mounting body 130 and the inner wall of the outer shell 110 forms the insertion space 111 for the insertion part 220 of the plug connector 20 to be inserted. Due to the restriction of the outer wall of the female mounting body 130 and the inner wall of the outer shell 110, the connection between the plug connector 20 and the socket connector 10 is more stable. On the side of the female mounting body 130 facing the opening of the insertion slot, there is an insertion cavity 131 extending in the insertion direction. Multiple insertion cavities 131 are provided and arranged side by side. In this embodiment, the insertion cavities 131 are arranged at intervals from top to bottom, and adjacent insertion cavities 131 are separated by partitions. Multiple female shielding shells 121 are correspondingly arranged in one insertion cavity 131. The setting of the female mounting body 130 not only makes the connection between the socket connector 10 and the plug connector 20 more stable, but also further isolates the female terminal body 122 and improves the electromagnetic shielding effect.

[0060] In one embodiment, a connecting plate is provided at the end of the insertion slot away from the insertion of the plug connector 20. The connecting plate connects the female end mounting body 130 and the outer shell 110. The female end mounting body 130 is disposed in the insertion slot and spaced apart from the outer shell 110 to form an insertion space 111. The female end mounting body 130, the connecting plate and the outer shell 110 are integrally formed, which improves the stability of the socket connector 10.

[0061] In one embodiment, such as Figure 5 As shown, a stop block 1233 is provided at the end of the outer wall of the female end insulating body 123 away from the opening of the docking cavity 1230. A limiting block 1234 is provided on the outer wall of the female end insulating body 123. The limiting block 1234 is inclined from the side near the docking cavity 1230 toward the side away from the docking cavity 1230, that is, the thickness of the limiting block 1234 on the side away from the opening of the docking cavity 1230 is greater than that on the side near the opening of the docking cavity 1230. The female end shielding shell 121 is provided with a limiting groove 1212. The female end shielding shell 121 is fitted onto the end of the female end insulating body 123 with the opening of the docking cavity 1230 and pushed toward the end away from the opening of the docking cavity 1230. 1. Until the female end shielding shell 121 is stopped by the stop block 1233 and can no longer be pushed, the limiting block 1234 is engaged in the limiting groove 1212. The setting of the stop block 1233 can prevent the female end shielding shell 121 from continuing to move away from the opening of the docking cavity 1230 and detach from the female end insulation body 123. The limiting block 1234 is engaged in the limiting groove 1212 to prevent the female end shielding shell 121 from moving away from the opening of the docking cavity 1230 and detaching from the female end insulation body 123. That is, the setting of the limiting block 1234 and the stop block 1233 makes the female end insulation body 123 and the female end shielding shell 121 stably assembled together, ensuring the electromagnetic shielding effect during operation.

[0062] In an embodiment of this utility model, guide blocks 1231 protrude from both sides of the outer wall of the female end insulating body 123. The guide blocks 1231 extend along the insertion direction of the mating cavity 1230. A locking block 1232 is provided at one end of the guide block 1231 away from the opening of the insertion cavity 131. Guide grooves 132 are provided on both sides of the inner wall of the insertion cavity 131. A locking groove 133 is provided in the guide groove 132. The guide block 1231 slides in the guide groove 132, and the locking block 1232 engages with the locking groove 133 to restrict the female end insulating body 123 from disengaging from the corresponding insertion cavity 131.

[0063] Please refer to Figures 3-5 and Figure 8 The female end shielding shell 121 has movable slots on both sides. When assembling the female end shielding shell 121, the guide block 1231 passes through the movable slots. The guide block 1231 extends from the end near the opening of the docking cavity 1230 to the end away from the opening of the docking cavity 1230. A locking block 1232 is provided at the end of the guide block 1231 away from the opening of the docking cavity 1230. The locking block 1232 is bent and connected to the guide block 1231 and bends and extends towards the direction of the insertion space 111. A locking block 1232 is provided on the inner wall of each insertion cavity 131. There is a guide groove 132 extending along the insertion direction. When assembling the female terminal module 120 and the female terminal mounting body 130, the female terminal module 120 is inserted and pushed inward at one end of the opening of the insertion cavity 131. As the female terminal module 120 moves toward the inside of the insertion cavity 131, the guide block 1231 slides in the guide groove 132 until the locking block 1232 at the end of the guide block 1231 engages with the locking groove 133 in the guide groove 132, so as to prevent the female terminal module 120 from detaching at one end of the opening of the insertion cavity 131.

[0064] Please refer to Figure 5 and Figure 6 In this embodiment of the present invention, clamping pieces 1211 are provided on both sides of the female end shielding shell 121. The clamping pieces 1211 are bent and connected to the female end shielding shell 121, and the clamping pieces 1211 extend from the opening of the mating cavity 1230 along the inner wall of the mating cavity 1230 toward the inside of the mating cavity 1230. The clamping pieces 1211 are used to abut against the plug connector 20 inserted into the mating cavity 1230. The clamping pieces 1211 are provided at the end of the female end shielding shell 121 near the opening of the insertion interface 1210, and are bent toward the inside of the insertion interface 1210. 211 extends toward the insertion direction of the insertion interface 1210. When assembling the female end shielding shell 121 and the female end insulating body 123, a clip 1211 is provided between the side wall of the female end insulating body 123 and the female end shielding shell 121. The clip 1211 fits against the inner wall of the mating cavity 1230 formed by the female end insulating body 123. When the male terminal module 230 of the plug connector 20 is inserted into the mating cavity 1230, the clip 1211 and the male terminal module 230 are adapted to abut against each other to avoid damage to the female end insulating body 123 during insertion.

[0065] Please refer to Figure 1 and Figure 7 In one embodiment, the outer wall of the female mounting body 130 is provided with at least one anti-misalignment groove 134. The anti-misalignment groove 134 extends along the insertion direction and is engaged with the insertion portion 220 of the plug connector 20. A corresponding anti-misalignment protrusion 221 is provided on the plug connector 20. When the plug connector 20 and the socket connector 10 are assembled, the insertion portion 220 is inserted into the insertion space 111. The anti-misalignment protrusion 221 is located in the anti-misalignment groove 134 to facilitate the insertion of the plug connector 20 and prevent displacement during the insertion process.

[0066] Please refer to Figure 1 and Figure 7 In one embodiment, mounting grooves 112 are respectively provided on opposite sides of the housing 110. The mounting grooves 112 are provided with slots 113 that penetrate the housing 110. When the plug connector 220 is inserted into the plug space 111, the positioning protrusion 222 on the plug connector 20 is inserted into the mounting groove 112 and engaged with the slot 113, preventing the plug connector 20 and the socket connector 10 from disengaging, thus ensuring a stable connection between the two. It also ensures more stable signal conduction between the male terminal module 230 and the female terminal module 120.

[0067] Please refer to Figure 9 and Figure 10 This utility model also proposes a plug connector 20, comprising:

[0068] Casing 210;

[0069] The plug portion 220 protrudes from one side of the housing 210 and has a mounting cavity with a mounting opening. The outer diameter of the plug portion 220 is smaller than the outer diameter of the housing 210. The plug portion 220 is used to plug into the plugging space 111 of the socket connector 10.

[0070] Multiple male terminal modules 230 are provided, each corresponding to a female terminal module 120. The male terminal modules 230 are arranged side by side in the mounting cavity. Each male terminal module 230 includes a male terminal shielding shell 231, a male terminal insulating body 233 disposed in the male terminal shielding shell, and a male terminal body 232 disposed in the male terminal insulating body 233. The male terminal insulating body 233 has a mating end that is inserted into the mating cavity 1230 of the socket connector. One end of the male terminal body 232 is connected to the circuit board, and the other end is exposed at the mating end. The male terminal insulating body 233 is exposed at the mounting port so that when the plug connector 20 and the socket connector 10 are plugged in, the male terminal body 232 is electrically connected to the female terminal body 122.

[0071] In the technical solution of this utility model, a plug-in portion 220 protrudes from one side of the housing 210. The plug-in portion 220 is used to plug into the plug-in space 111 of the female connector. The number and position of the male terminal modules 230 correspond to the number and position of the female terminal modules 120 on the socket connector 10. Each male terminal module 230 includes a male terminal shielding shell 231 and a male terminal body 232 inside the male terminal shielding shell 231. That is, the male terminal body 232 is isolated by the male terminal shielding shell 231. The male terminal shielding shell 231 is made of metal. The male terminal shield 231 can avoid electromagnetic interference between the male terminal bodies 232, making signal transmission more stable. When the plug connector 20 and the socket connector 10 are connected, the insertion part 220 is inserted into the insertion space 111 of the socket connector 10, and the male terminal body 232 is inserted into the insertion interface 1210 and connects with the female terminal body 122 to realize signal transmission. Since the plug connector 20 has multiple male terminal modules 230, it can correspond to multiple different devices, reducing the size of the connector and meeting the connection of multiple devices.

[0072] Specifically, the housing 210 and the plug portion 220 are integrally formed. The plug portion 220 is located on one side of the housing 210 and its outer diameter is smaller than that of the housing 210, so that the housing 210 and the outer shell 110 can abut against each other when inserted into the plug space 111. In addition, the male terminal modules 230 arranged side by side in the mounting cavity can be arranged horizontally side by side or spaced apart from top to bottom. In this embodiment, there are two male terminal modules 230, which are arranged from top to bottom. The end of the male terminal module 230 away from the mounting port is soldered to the circuit board. The end of the male terminal shield 231 away from the mounting port is also soldered to the circuit board. Each male terminal module 230 is connected to a different circuit board and connects to different devices. When the male terminal module 230 corresponds to two different devices, the socket connector 10 is installed on one device. When the socket connector 10 and the plug connector 20 are plugged in, the two devices of the plug connector 20 can be connected to the devices of the socket connector 10, reducing the volume occupied by the connector.

[0073] The male terminal module 230 includes a male terminal shielding shell 231, a male terminal body 232, and a male terminal insulating body 233. The male terminal insulating body 233 includes a base and a tongue plate. The tongue plate is configured as a mating end and extends toward the connection cavity. The base is disposed inside the male terminal shielding shell 231. The male terminal body 232 includes a plurality of male terminals. Multiple terminal slots are respectively provided on the upper and lower sides of the tongue plate for setting the male terminals. The male terminals are exposed on the tongue plate. The tongue plate is used to be inserted into the mating cavity 1230 of the socket connector 10. The male terminals above the tongue plate mate with the terminals at the upper part of the mating cavity 1230, and the male terminals below the tongue plate mate with the terminals at the lower part of the mating cavity 1230. Adjacent male terminal modules 230 are separated by the male terminal shielding shell 231 to reduce electromagnetic interference between male terminal bodies 232.

[0074] Please refer to Figure 9 and Figure 11 In an embodiment of this utility model, the plug connector 20 further includes a male end mounting body 240, which has connecting cavities arranged side by side and spaced apart. The connecting cavities are connected to the mounting cavities, and each male end module 230 is correspondingly disposed in a connecting cavity.

[0075] Please refer to Figure 9 and Figure 11 The male terminal mounting body 240 is disposed at the end of the mounting cavity away from the mounting opening and is connected to the inner wall of the mounting cavity. In one embodiment, the male terminal mounting body 240, the housing 210, and the plug-in portion 220 are integrally formed. A series of connecting cavities are provided on the male terminal mounting body 240, with each connecting cavity corresponding to a male terminal module 230. Different male terminal bodies 232 are separated by the male terminal shielding shell 231 and the male terminal mounting body 240, further improving the electromagnetic shielding effect and ensuring signal transmission quality. Furthermore, the male terminal mounting body 240 also makes the male terminal shielding shell 231 more stable within the connecting cavity, enabling it to withstand the stress generated by repeated insertions and removals of the plug connector 20 and the socket connector 10.

[0076] Please refer to Figure 11 In an embodiment of this utility model, the inner wall of the plug portion 220 is provided with a foolproof protrusion 221. The foolproof protrusion 221 is used to engage with the socket connector 10. When the plug connector 20 and the socket connector 10 are plugged in, the foolproof protrusion 221 is disposed in the foolproof groove 134 of the socket connector 10. As the plug connector 20 moves toward the socket connector 10, the foolproof protrusion 221 moves in the foolproof groove 134 to guide the plug connector 20 to avoid deviation affecting signal conduction.

[0077] In one embodiment, such as Figure 9 and 11 As shown, the outer wall of the plug portion 220 is provided with a positioning protrusion 222. The positioning protrusion 222 is used to engage with the socket connector 10. The positioning protrusion 222 is inclined from the end near the mounting opening to the end away from the mounting opening, that is, the thickness of the end of the positioning protrusion 222 away from the mounting opening is greater than the thickness of the end near the mounting opening. When the plug portion 220 is inserted into the plugging space 111, the positioning protrusion 222 moves along the mounting groove 112 and inserts into the bayonet 113, engaging with the bayonet 113. This can limit the pull-out of the plug connector 20 in the socket connector 10 and ensure the stability of the connection.

[0078] Please refer to Figure 10 and Figure 12In an embodiment of this utility model, clearance grooves 2331 are respectively provided on both sides of the mating end, and a spring piece 2311 is respectively provided on both sides of the male end shielding shell 231. The spring piece 2311 is located in the clearance groove 2331 and is used to abut against the inner wall of the socket connector 10.

[0079] Specifically, a clearance groove 2331 is provided on the side of the tongue plate, which extends along the insertion direction. A spring piece 2311 is provided on the side of the male end shielding shell 231. After the male end shielding shell 231 and the male end insulating body 233 are assembled, the spring piece 2311 abuts in the clearance groove 2331. When the tongue plate is inserted into the mating cavity 1230, the spring piece 2311 abuts against the clip 1211 in the mating cavity 1230, making the connection between the male terminal module 230 and the female terminal module 120 more stable.

[0080] This utility model also proposes a connector assembly, such as Figure 13 As shown, the connector assembly includes a plug connector 20 and a socket connector 10. The specific structures of the socket connector 10 and the plug connector 20 are as described in the above embodiments. Since this connector assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The insertion part 220 is inserted into the insertion space 111, and the male terminal module 230 is electrically connected to the female terminal module 120.

[0081] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
