The plug-in component is electrically connected to the optoelectronic module, and the optoelectronic module can be electrically connected to a cable inserted into the plug shell.

[0003] In order to seal and protect the optoelectronic module, it is generally necessary to provide an opening on the plug shell, inject insulating material into the plug shell through the opening, and fix the connector and the optoelectronic module while the insulating material is solidifying, while sealing and protecting the optoelectronic module. However, providing an opening on the plug shell will reduce the anti-electromagnetic interference performance of the plug shell. Summary of the invention

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a connector, including a housing, a potting sleeve, a plug-in component, and an optoelectronic module, wherein the potting sleeve is an insulating structural component.

[0007] The potting sleeve is detachably arranged in the shell body, the plug-in connector has an electrical connection end and a plug-in end for docking with the connecting socket, the plug-in connector is arranged at one end of the potting sleeve, and the electrical connection end faces the potting space in the potting sleeve, the photoelectric module is arranged in the potting space and electrically connected to the electrical connection end, and the potting sleeve is provided with a potting port and a threading port connected to the potting space.

[0008] In a second aspect, an embodiment of the present application further provides a cable assembly, comprising a cable and a connector as described in any of the above embodiments, wherein the cable is inserted into a housing through a threading port and is electrically connected to an optoelectronic module.

[0009] In the embodiment of the present application, a potting sleeve is provided in the shell, a connector is provided at one end of the potting sleeve, and the electrical connection end of the connector faces the potting space in the potting sleeve, the optoelectronic module is provided in the potting space and electrically connected to the electrical connection end, the potting port on the potting sleeve is used to inject insulating material into the potting space, and the threading port is used to thread the cable. During actual assembly, the cable can be electrically connected to the optoelectronic module in the potting sleeve through the threading port, and then the insulating material can be injected into the potting space through the potting port to seal and protect the optoelectronic module, and finally the potting sleeve after potting is assembled into the shell. It can be seen that in this embodiment, the optoelectronic module is sealed and protected by injecting insulating material into the potting port on the potting sleeve without providing an opening on the shell, which can solve the problem of reducing the anti-electromagnetic interference performance of the shell due to providing an opening on the shell.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0024] The connector and cable assembly provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 As shown, an embodiment of the present application discloses a connector, including a housing 100, a potting sleeve 200, a connector 300 and an optoelectronic module 400, wherein the potting sleeve 200 is an insulating structural member. Specifically, the housing 100 is the main part of the connector that resists electromagnetic interference, and it can be made of conductive materials such as metal; the optoelectronic module 400 includes a circuit board 410 and an optical module arranged on the circuit board 410, and the optical module can be connected to the optical fiber in the cable 900 described below to realize the conversion of optical and electrical signals, and the circuit board 410 can realize the electrical connection of the cable 900, the connector 300 and the optical module. Optionally, the connector also includes a mesh tail structure 840, which wraps the end of the housing 100 away from the connector 300, and the mesh tail structure 840 wraps a part of the cable 900.

[0026] The potting sleeve 200 is detachably arranged in the housing 100, that is, the potting sleeve 200 and the housing 100 are split structures, and the potting sleeve 200 can be taken out from the housing 100. The plug connector 300 has an electrical connection end and a plug end for docking with the connection seat. The plug connector 300 is arranged at one end of the potting sleeve 200, and the electrical connection end faces the potting space 210 in the potting sleeve 200. The optoelectronic module 400 is arranged in the potting space 210 and is electrically connected to the electrical connection end. The potting sleeve 200 is provided with a potting port 220 and a threading port 230 that are connected to the potting space 210. Optionally, the plug end can be located in the housing 100 or outside the housing 100. When the plug end is located in the housing 100, the housing 100 can protect the plug end to prevent the plug end from being damaged. The plug connector 300 includes an insulating rubber core 320 and a contact 330 . A portion of the contact 330 is located inside the insulating rubber core 320 . The contact 330 has the electrical connection end and the plug-in end as described above.

[0027] In the embodiment of the present application, a potting sleeve 200 is provided in the housing 100, a plug-in connector 300 is provided at one end of the potting sleeve 200, and the electrical connection end of the plug-in connector 300 faces the potting space 210 in the potting sleeve 200, a photoelectric module 400 is provided in the potting space 210 and electrically connected to the electrical connection end, a potting port 220 on the potting sleeve 200 is used to inject insulating material into the potting space 210, and a threading port 230 is used to thread the cable 900. During actual assembly, the cable 900 can be electrically connected to the photoelectric module 400 in the potting sleeve 200 through the threading port 230, and then the insulating material can be injected into the potting space 210 through the potting port 220 to seal and protect the photoelectric module 400, and finally the potting sleeve 200 after potting is assembled into the housing 100. It can be seen that in this embodiment, insulating material is injected into the filling port 220 on the potting sleeve 200 to seal and protect the optoelectronic module 400 without providing an opening on the housing 100. This can solve the problem of reducing the anti-electromagnetic interference performance of the housing 100 due to providing an opening on the housing 100.

[0028] In addition, since the potting sleeve 200 disposed in the housing 100 is not convenient to be grounded, the embodiment of the present application sets the potting sleeve 200 as an insulating structural member, so that the electromagnetic wave will not be conducted to the potting sleeve 200 when passing through the housing 100, thereby avoiding the problem of being unable to discharge the electromagnetic wave due to the electromagnetic wave being conducted to the potting sleeve 200. Furthermore, the potting sleeve 200 is detachably disposed in the housing 100, so that when the optoelectronic module 400 is damaged, the potting sleeve 200 injected with insulating material can be removed from the housing 100, and then the connector can be repaired, which is convenient for repairing the connector.

[0029] In order to increase the stability of the connection between the connector and the connection base, in an optional embodiment, refer to Figure 1 , 2 6. The connector further includes a locking member 500, which includes a first elastic deformation portion 510, one end of which is provided with a snap-fitting portion 520, the other end of which is connected to the outer peripheral surface of the housing 100, the snap-fitting portion 520 can be snap-fitted with the connection seat, and when the snap-fitting portion 520 is compressed, the first elastic deformation portion 510 is deformed, and the snap-fitting portion 520 can be released from the connection seat. Specifically, a snap-fitting portion that matches the snap-fitting portion 520 is provided on the connection seat, the snap-fitting portion 520 can be snap-fitted with the snap-fitting portion, the snap-fitting portion 520 can be a snap-fitting protrusion or a snap-fitting depression, and the snap-fitting portion can be a snap-fitting depression or a snap-fitting protrusion.

[0030] In this embodiment, during the process of inserting the connector into the connection seat, the connector can be engaged with the connection seat to fix the relative position between the connector and the connection seat, prevent the connector from falling off from the connection seat, and thus increase the stability of the connection between the connector and the connection seat; in addition, the connector can be removed from the connection seat by pressing the engaging portion 520. In order to reduce the resistance when the connector is inserted into the connection seat, a first guide surface can be provided on the connection seat, and / or a second guide surface can be provided on the engaging portion 520, and the first guide surface and / or the second guide surface are provided so that when the connector is inserted, the first elastic deformation portion 510 is deformed by the first guide surface and / or the second guide surface. The specific operation process is as follows: the connector is inserted in a direction close to the connection seat, and as the connector approaches the connection seat, under the action of the first guide surface and / or the second guide surface, the connection seat presses the engaging portion 520 to elastically deform the first elastic deformation portion 510, and as the connector is continuously inserted, the engaging portion 520 will eventually engage with the engaging portion under the action of the elastic restoring force of the first elastic deformation portion 510. Furthermore, the outer circumferential surface of the housing 100 is provided with an escape space 150, and when the first elastic deformation portion 510 is in a deformed state, at least part of the clamping portion 520 is located in the escape space 150; when the first elastic deformation portion 510 is in a natural state or a state with a small deformation amount, the clamping portion 520 is located outside the escape space 150. In this way, the clamping portion 520 can be arranged closer to the outer circumferential surface of the housing 100, thereby reducing the space outside the housing 100 occupied by the clamping portion 520.

[0031] Further, the first elastic deformation part 510 is a first elastic plate extending along the axial direction of the housing 100. The first elastic plate is a plate-shaped elastic member. Compared with a spring and a spring sheet, the first elastic plate has a higher tensile strength. Therefore, when the connector is subjected to a pulling force, the first elastic member is not easily deformed by pulling, thereby preventing the connector from being pulled out of the connection seat, thereby further improving the stability of the connection between the connector and the connection seat. Further, the locking member 500 also includes a connecting body part 540, which is connected to the outer peripheral surface of the housing 100. There are multiple first elastic plates, each of which is connected to the connecting body part 540 and is distributed at intervals along the circumference of the housing 100, and each of the first elastic plates is connected to a clamping part 520. In this embodiment, a clamping ring 530 can be set at the end of the connecting body part 540, and then the connecting body part 540 is set on the outer peripheral surface of the housing 100 through the clamping ring 530. The number of the clamping parts 520 is multiple, so that the connection points between the connector and the connection seat can be increased, thereby improving the stability of the connection between the connector and the connection seat. Further, a reinforcing plate 550 connected to the connecting body 540 is provided between two adjacent first elastic plates, and a deformation gap is provided between the reinforcing plate 550 and the first elastic plate. The provision of the reinforcing plate 550 can increase the structural strength of the first elastic deformation part 510.

[0032] In an alternative embodiment, see Figure 1 , 2 6. The connector also includes an unlocking member 600, which is sleeved on the outside of the shell 100. The unlocking member 600 is provided with an unlocking hole 610 that penetrates the unlocking member 600. One end of the clamping portion 520 passes through the unlocking hole 610 and protrudes from the unlocking hole 610. The unlocking member 600 can slide relative to the shell 100 to press the clamping portion 520 to cause the first elastic deformation portion 510 to deform. In this embodiment, the clamping portion 520 is a clamping protrusion, a part of the clamping portion 520 is located in the unlocking hole 610, and the part of the clamping portion 520 protruding from the unlocking hole 610 is used to be clamped and matched with the connecting seat, and the part of the clamping portion 520 located in the unlocking hole 610 can contact the hole wall of the unlocking hole 610. When the unlocking member 600 slides from the first position to the second position, the hole wall of the unlocking hole 610 presses the clamping portion 520 to deform the first elastic deformation portion 510, so that the clamping portion 520 is disengaged from the connecting seat, and the connector can be removed from the connecting seat. It can be seen that in this embodiment, the connector can be disengaged from the connecting seat by sliding the unlocking member 600, which is convenient for user operation. In addition, the unlocking member 600 is sleeved on the outside of the first elastic deformation portion 510, so that the unlocking member 600 can protect the first elastic deformation portion 510, thereby preventing the first elastic deformation portion 510 from being damaged.

[0033] In an optional embodiment, at least two anti-skid protrusions 620 are arranged at intervals on the outer circumferential surface of the unlocking member 600 along the axial direction of the housing 100, each anti-skid protrusion 620 extends along the circumferential direction of the unlocking member 600, and a gripping groove 630 is formed between two adjacent anti-skid protrusions 620. In this embodiment, a gripping groove 630 is formed between two adjacent anti-skid protrusions 620, and the gripping groove 630 is used to accommodate at least one finger of the operator. When the unlocking member 600 needs to be slid, the operator can place the finger in the gripping groove 630, and then apply a force to the unlocking member 600 to make the unlocking member 600 slide relative to the housing 100. In the process of the operator applying a force to the unlocking member 600, the anti-skid protrusion 620 can limit the finger to prevent the finger from slipping relative to the unlocking member 600, thereby making it easier for the operator to slide the unlocking member 600.

[0034] In an alternative embodiment, see Fig. 9The connector further includes an elastic clamping member 700, which includes a second elastic deformation portion 710, one end of which is provided with a clamping portion 720, and the other end of which is connected to the housing 100. When the second elastic deformation portion 710 is in a deformed state, the clamping portion 720 can clamp the cable 900 that is inserted into the housing 100. Optionally, the second elastic deformation portion 710 can be an elastic component such as a spring, a spring sheet, or an elastic plate. In this embodiment, the second elastic deformation portion 710 can be deformed so that the clamping portion 720 clamps the cable 900, thereby preventing the cable 900 from being disconnected from the optoelectronic module 400 under the pull of an external force.

[0035] In an optional embodiment, the shell 100 includes a front shell 110 and a rear shell 120 connected to each other, the rear shell 120 and the connector 300 are respectively located on opposite sides of the front shell 110, and the end of the second elastic deformation portion 710 away from the clamping portion 720 is connected to the front shell 110, the inner surface of the rear shell 120 has a pressing surface 121, and the clamping portion 720 has a force surface 721. When the rear shell 120 moves relative to the front shell 110, the pressing surface 121 presses the force surface 721 to put the second elastic deformation portion 710 in a deformed state.

[0036] In this embodiment, after the cable 900 is inserted into the housing 100, the rear housing 120 can be controlled to move relative to the front housing 110, so that the pressing surface 121 of the rear housing 120 presses the force-bearing surface 721 of the clamping portion 720. In this process, the second elastic deformation portion 710 is elastically deformed, so that the clamping portion 720 clamps the cable 900. It can be seen that in this embodiment, the clamping portion 720 is pressed by the housing 100 itself, without the need to add an additional driving component to press the clamping portion 720, thereby simplifying the structure of the connector; in addition, the displacement of the pressing portion can be controlled by controlling the stroke of the rear housing 120 relative to the front housing 110, which can not only control the clamping force of the elastic clamping member 700 on the cable 900, but also enable the elastic clamping member 700 to adapt to cables 900 of various specifications. It should be noted that in this embodiment, in order for the pressing surface 121 to press the force-bearing surface 721, the rear housing 120 can move in a direction close to the front housing 110 or in a direction away from the front housing 110. Optionally, the pressing surface 121 can be a pressing inclined surface or a frustum surface, and the force-bearing surface 721 can be a force-bearing inclined surface or a frustum surface.

[0037] Furthermore, the front shell 110 and the rear shell 120 are detachably connected so that the rear shell 120 can move relative to the front shell 110 , and the potting sleeve 200 is located in the front shell 110 . During the process of assembling the rear shell 120 to the front shell 110 , the pressing surface 121 presses the force-bearing surface 721 . In this embodiment, the front shell 110 and the rear shell 120 can be detachably connected by means of threaded connection, clamping, etc. Therefore, before inserting the cable 900 into the shell 100, the rear shell 120 can be removed from the front shell 110 first, so as to facilitate the electrical connection of the cable 900 with the optoelectronic module 400 located in the front shell 110, so as to simplify the wiring difficulty; after the wiring is completed, the rear shell 120 can be assembled to the front shell 110. At this time, the rear shell 120 moves relative to the front shell 110 in a direction close to the front shell 110, so that the pressing surface 121 of the rear shell 120 presses the force surface 721 of the clamping part 720, and then the clamping part 720 clamps the cable 900.

[0038] Optionally, the second elastic deformation portion 710 can also be configured as follows: when the cable 900 is inserted into the shell 100, the cable 900 can cause the second elastic deformation portion 710 to be in a deformed state. When this method is adopted, the cable 900 can be inserted into the shell 100 so that the clamping portion 720 can clamp the cable 900, and the clamping sensitivity is high.

[0039] In an optional embodiment, the elastic clamping member 700 is a conductive structural member, and the second elastic deformation portion 710 includes a base portion 711 and a deformation portion 712, the base portion 711 is connected to the shell 100, and the two ends of the deformation portion 712 are respectively connected to the base portion 711 and the clamping portion 720, the base portion 711 is in electrical contact with the inner wall of the shell 100, and the clamping portion 720 is used to clamp the shielding layer 940 of the cable 900. In this embodiment, the base portion 711 is in electrical contact with the inner wall of the shell 100. After the cable 900 is inserted into the shell 100, the clamping portion 720 clamps the shielding layer 940 of the cable 900, so that the shielding layer 940 of the cable 900 can be electrically connected to the shell 100 through the elastic clamping member 700. In this way, the electromagnetic waves conducted in the shielding layer 940 of the cable 900 can be conducted to the shell 100 through the elastic clamping member 700, and then conducted to the ground through the connecting seat connected to the connector, thereby preventing the electromagnetic waves conducted in the shielding layer 940 of the cable 900 from causing electromagnetic interference to the electrical components in the shell 100.

[0040] In the previous embodiment, there may be a gap between the base part 711 and the inner peripheral wall of the housing 100, and some electromagnetic waves may enter the housing 100 through the gap, thereby interfering with the electrical components in the housing 100. Therefore, in an optional embodiment, a conductive seal 810 is provided between the base part 711 and the inner peripheral wall of the housing 100, and the conductive seal 810 can block the gap between the base part 711 and the inner peripheral wall of the housing 100, thereby preventing the electromagnetic waves conducted in the shielding layer 940 of the cable 900 from entering the housing 100, thereby preventing the electromagnetic waves from electromagnetically interfering with the electrical components in the housing 100. Optionally, the conductive seal 810 can be a conductive member with a sealing function such as conductive glue or conductive plastic.

[0041] In the case where the front shell 110 and the rear shell 120 are detachably connected by threaded connection, in the process of rotating the rear shell 120 to fix the rear shell 120 to the front shell 110, the pressing surface 121 of the rear shell 120 will contact the force-bearing surface 721 of the pressing portion, so friction will be generated between the pressing surface 121 and the force-bearing surface 721. Under the action of the friction between the pressing surface 121 and the force-bearing surface 721, continuing to rotate the rear shell 120 may drive the elastic clamping member 700 to rotate together with the rear shell 120, and the elastic clamping member 700 clamps the cable 900, so the cable 900 will also rotate with the elastic clamping member 700, and the optoelectronic module 400 is relatively fixed, so the rotation of the cable 900 will cause the cable 900 to be disconnected from the optoelectronic module 400. Optionally, the deformation portion 712 can be an elastic component such as a spring, a spring sheet, an elastic plate, etc.

[0042] In an optional embodiment, the second elastic deformation portion 710 includes a base portion 711 and a deformation portion 712, the two ends of the deformation portion 712 are respectively connected to the base portion 711 and the clamping portion 720, the base portion 711 is sleeved in the housing 100, one of the base portion 711 and the housing 100 is provided with an insertion recess 111, and the other is provided with an insertion protrusion 713, at least part of the insertion protrusion 713 is inserted into the insertion recess 111 to limit the elastic clamping member 700 from rotating around its own axis. Optionally, in the case where the housing 100 includes a front shell 110 and a rear shell 120, one of the base portion 711 and the front shell 110 is provided with an insertion recess 111.

[0043] This embodiment can be combined with a technical solution in which the front shell 110 and the rear shell 120 are detachably connected by means of threaded connection. Since one of the base portion 711 and the shell body 100 is provided with a plug-in protrusion 713, and the other is provided with a plug-in recess 111 that cooperates with the plug-in protrusion 713, the plug-in protrusion 713 and the inner wall of the plug-in recess 111 cooperate with the circumferential upper limit of the shell body 100. Therefore, in the process of rotating the rear shell 120, the inner wall of the plug-in recess 111 can limit the plug-in protrusion 713, thereby inhibiting the elastic clamping member 700 from rotating around its own axis, thereby avoiding the cable 900 from being disconnected from the optoelectronic module 400 due to the rotation of the elastic clamping member 700.

[0044] The photoelectric module 400 is generally electrically connected to the connector 300 through the FPC soft board. When the insulating material is injected into the potting space 210, the insulating material will contact and squeeze the photoelectric module 400. If the photoelectric module 400 is not supported, the position of the photoelectric module 400 is easy to shift, which will not only reduce the distance between the photoelectric module 400 and the housing 100, but also excessively bend the FPC soft board, which may cause the electromagnetic waves passing through the housing 100 to interfere with the circuit board 410 and the FPC soft board of the photoelectric module 400. Therefore, in an optional embodiment, the photoelectric module 400 includes a circuit board 410, and the circuit board 410 has a first edge and a second edge. The potting sleeve 200 is provided with a first mounting portion 240 and a second mounting portion 250, and the first mounting portion 240 and the second mounting portion 250 are respectively located on opposite sides of the potting sleeve 200, and the first edge is supported on the first mounting portion 240, and the second edge is supported on the second mounting portion 250. In this embodiment, the first mounting portion 240 and the second mounting portion 250 jointly support the circuit board 410, so as to prevent the optoelectronic module 400 from moving downward during the process of injecting insulating material into the potting space 210, thereby preventing the position of the optoelectronic module 400 from being offset, thereby controlling the distance between the optoelectronic module 400 and the housing 100 within a suitable range, and preventing the FPC soft board from being excessively bent, thereby reducing the risk of electromagnetic waves passing through the housing 100 interfering with the circuit board 410 and the FPC soft board of the optoelectronic module 400. Optionally, the first mounting portion 240 and the second mounting portion 250 can both be mounting protrusions protruding from the inner wall of the potting sleeve 200, and the circuit board 410 is supported by the top wall of the mounting protrusions.

Optionally, both the first mounting opening and the second mounting opening may pass through or not pass through the potting sleeve 200. In this embodiment, the first edge is limitedly fitted with the inner wall of the first mounting opening, and the second edge is limitedly fitted with the inner wall of the second mounting opening. In this way, the first mounting portion 240 and the second mounting portion 250 can not only prevent the optoelectronic module 400 from moving downward, but also prevent the optoelectronic module 400 from moving upward, leftward, and rightward, thereby further preventing the distance between the optoelectronic module 400 and the housing 100 from becoming smaller, and further preventing the FPC soft board from being excessively bent; in addition, after the optoelectronic module 400 is prevented from moving leftward and rightward by the inner walls of the first mounting opening and the second mounting opening, the optoelectronic module 400 can be prevented from being disconnected from the connector 300 and the cable 900 respectively.

[0046] Furthermore, the potting sleeve 200 includes a first sleeve 260 and a second sleeve 270 which are separately arranged. The first sleeve 260 can be connected to the second sleeve 270. The first sleeve 260 is provided with a first notch and a second notch on the end surface facing the second sleeve 270, and the first notch and the second notch are respectively located on the opposite sides of the first sleeve 260. The second sleeve 270 is provided with a third notch and a fourth notch on the end surface facing the first sleeve 260, and the third notch and the fourth notch are respectively located on the opposite sides of the second sleeve 270. The first mounting port includes the first notch and the third notch, and the second mounting port includes the second notch and the fourth notch. The first sleeve 260 and the second sleeve 270 of this embodiment are separately arranged, so it is convenient to place the circuit board 410 in the first mounting port and the second mounting port.

[0047] When the connector is used in the medical field, it is necessary to disinfect the connector after it has been used for a period of time. The disinfectant can easily enter the housing 100 through the opening of the housing 100 near the plug-in end, which may not only damage the vital parts in the housing 100, but also cause pollution by the disinfectant remaining in the housing 100. In an optional embodiment, the connector also includes a waterproof cap 820, which is detachably connected to the housing 100, and the waterproof cap 820 can cover the opening of the housing 100 near the plug-in end. In this embodiment, when the waterproof cap 820 is connected to the housing 100, the waterproof cap 820 can block the opening of the housing 100 near the plug-in end, so the waterproof cap 820 can be assembled to the housing 100 before the connector is disinfected, so as to prevent the disinfectant from entering the housing 100 when the connector is disinfected, thereby preventing the disinfectant from damaging the vital parts in the housing 100 and the disinfectant from remaining in the housing 100. This embodiment can also be combined with a solution in which the shell 100 includes a front shell 110 and a rear shell 120, and the front shell 110 and the rear shell 120 are detachably connected. In this case, the waterproof cap 820 can cover the connection between the front shell 110 and the rear shell 120 to prevent the disinfectant from entering the shell 100 through the connection between the front shell 110 and the rear shell 120.

[0048] In an optional embodiment, the outer surface of the connector includes a mating surface 130 that is mated with the connection seat, and the portion of the outer surface other than the mating surface 130 is an insulating surface 140. Figure 7 , Figure 7 The outline of the medium thick solid line is the insulating surface 140. After the connector is inserted into the connection seat, the portion of the outer surface of the connector opposite to the connection seat is the mating surface 130, and the portion of the outer surface of the connector outside the connection seat is the insulating surface 140. The portion of the outer surface of the connector other than the mating surface 130 is the insulating surface 140, which can prevent static electricity from being generated on the portion of the outer surface other than the mating surface 130.

[0049] Optionally, the locking member 500 and the unlocking member 600 may be insulating structural members, and an insulating bushing 830 may be provided on the outer peripheral surface of the housing 100, and the insulating bushing 830 covers the portion of the outer surface of the housing 100 that is not covered by the unlocking member 600 and the insulating structural member except the mating surface 130, so that the portion of the outer surface of the connector except the mating surface 130 may be an insulating surface 140. Further, the waterproof cap 820 and the insulating bushing 830 may be detachably connected by threaded connection, snap connection, etc., so that the insulating bushing 830 may not only install the waterproof cap 820, but also insulate and separate the outer surface of the housing 100, so as to achieve a one-item-multiple-purposes effect. Further, the insulating bushing 830 is sleeved on the rear housing 120, and a sealing ring 860 may be provided at least one of between the insulating bushing 830 and the rear housing 120, between the rear housing 120 and the front housing 110, and between the rear housing 120 and the waterproof cap 820.

[0050] In addition, the locking member 500 and the unlocking member 600 may also be conductive structural members. In this case, an insulating layer may be provided on the outer surface of the connector except for the mating surface 130 , thereby making the outer surface of the connector except for the mating surface 130 an insulating surface 140 .

[0051] In an optional embodiment, the connector 300 is provided with a first positioning portion 310, and the potting sleeve 200 is provided with a second positioning portion 280, and the first positioning portion 310 is positioned and matched with the second positioning portion 280. In this embodiment, the potting sleeve 200 can be positioned and arranged on the connector 300 by the first positioning portion 310 and the second positioning portion 280, so that in the process of injecting insulating material into the filling space 210, the potting sleeve 200 can be prevented from moving relative to the connector 300, thereby preventing the potting sleeve 200 from detaching from the connector 300. Optionally, the first positioning portion 310 can be a positioning convex portion or a positioning concave portion, and the second positioning portion 280 can be a positioning concave portion or a positioning convex portion.

[0052] like Figures 8 to 11 As shown, the embodiment of the present application further discloses a cable assembly, including a cable 900 and a connector as described in any of the above embodiments, the cable 900 is inserted into the housing 100 through the threading port 230, and is electrically connected to the optoelectronic module 400. In the embodiment of the present application, a potting sleeve 200 is provided in the housing 100, a plug-in connector 300 is provided at one end of the potting sleeve 200, and the electrical connection end of the plug-in connector 300 faces the potting space 210 in the potting sleeve 200, the optoelectronic module 400 is provided in the potting space 210 and is electrically connected to the electrical connection end, the potting port 220 on the potting sleeve 200 is used to inject insulating material into the potting space 210, and the threading port 230 is used to thread the cable 900. During actual assembly, the cable 900 can be electrically connected to the optoelectronic module 400 in the potting sleeve 200 through the threading port 230, and then the insulating material can be injected into the potting space 210 through the potting port 220 to seal and protect the optoelectronic module 400, and finally the potting sleeve 200 after potting is assembled into the housing 100. It can be seen that in this embodiment, the optoelectronic module 400 is sealed and protected by injecting insulating material into the potting port 220 on the potting sleeve 200, without providing an opening on the housing 100, so that the problem of reducing the anti-electromagnetic interference performance of the housing 100 due to providing an opening on the housing 100 can be solved.

[0053] In addition, since the potting sleeve 200 disposed in the housing 100 is not convenient to be grounded, the embodiment of the present application sets the potting sleeve 200 as an insulating structural member, so that the electromagnetic wave will not be conducted to the potting sleeve 200 when passing through the housing 100, thereby avoiding the problem of being unable to discharge the electromagnetic wave due to the electromagnetic wave being conducted to the potting sleeve 200. Furthermore, the potting sleeve 200 is detachably disposed in the housing 100, so that when the optoelectronic module 400 is damaged, the potting sleeve 200 injected with insulating material can be removed from the housing 100, and then the connector can be repaired, which is convenient for repairing the connector.

[0054] In an optional embodiment, the connector further comprises an elastic clamping member 700, the elastic clamping member 700 comprises a second elastic deformation portion 710, one end of the second elastic deformation portion 710 is provided with a clamping portion 720, the other end of the second elastic deformation portion 710 is connected to the housing 100, and the outer peripheral surface of the cable 900 is provided with a limiting convex portion 910, when the second elastic deformation portion 710 is in a deformed state, the clamping portion 720 can clamp the cable 900 inserted into the housing 100, and the limiting convex portion 910 can cooperate with the clamping portion 720 to limit the position in the first direction, wherein the first direction is a direction extending from an end of the housing 100 close to the plug connector 300 to an end of the housing 100 away from the plug connector 300. If the outer peripheral surface of the cable 900 is not provided with a limiting convex portion 910, after the cable 900 is inserted into the housing 100, the cable 900 is only clamped by the clamping portion 720, and the cable 900 is easily disconnected from the optoelectronic module 400 when subjected to a large pulling force. In this embodiment, a limiting protrusion 910 is provided on the outer peripheral surface of the cable 900. When the clamping portion 720 clamps the cable 900 that passes through the shell 100, and the clamping portion 720 clamps the cable 900, the limiting protrusion 910 cooperates with the clamping portion 720 to limit the position in the first direction. Therefore, the cable 900 will be subjected to the clamping force applied to it by the clamping portion 720, and the clamping portion 720 can also stop the limiting protrusion 910 on the cable 900. Therefore, when the cable 900 is subjected to a pulling force in the first direction, it is not easy to be disconnected from the optoelectronic module 400.

[0055] The cable 900 includes an outer sheath 920 and a core wire structure within the outer sheath 920, the core wire structure including an anti-drawing layer 930. If the core wire structure is subjected to a pulling force but the outer sheath 920 is not subjected to a pulling force, if a limiting protrusion 910 is provided on the outer peripheral surface of the outer sheath 920, the internal core wire structure will also be pulled, thereby disconnecting the core wire structure from the optoelectronic module 400. In an optional embodiment, the cable 900 has an outer sheath 920 and an anti-drawing layer 930, the anti-drawing layer 930 includes a first anti-drawing portion and a second anti-drawing portion 931 connected to each other, the outer sheath 920 is sleeved on the outside of the first anti-drawing portion, the second anti-drawing portion 931 is bent relative to the first anti-drawing portion in a direction away from the connector 300, and the second anti-drawing portion 931 covers a portion of the outer surface of the outer sheath 920, and the limiting protrusion 910 includes a second anti-drawing portion 931 and a crimping ring 911, and the crimping ring 911 is sleeved and crimped on the outside of the second anti-drawing portion 931. In this embodiment, the outer sheath 920 is sleeved on the outside of the first tensile part, and the second tensile part 931 exceeds the left end of the outer sheath 920. The second tensile part 931 can be bent to the right to cover a part of the outer surface of the outer sheath 920. Then, the crimping ring 911 can be used to crimp the second tensile part 931, so as to fix the crimping ring 911 to the outer peripheral surface of the cable 900. It can be seen that in this embodiment, the outer sheath 920 and the core wire structure disposed therein are connected as a whole through the crimping ring 911 and the second tensile part 931. Whether the core wire structure in the outer sheath 920 is only subjected to the pulling force or the outer sheath 920 is only subjected to the pulling force, the cooperation between the limiting protrusion 910 and the clamping part 720 can prevent the core wire structure and the outer sheath 920 from being pulled, thereby preventing the core wire structure from being disconnected from the optoelectronic module 400. In addition, the second tensile-resistant portion 931 is located between the crimping ring 911 and the outer sheath 920, that is, there is a metal layer between the crimping ring 911 and the outer sheath 920, which can improve the connection strength between the crimping ring 911 and the cable 900 after crimping, and the second tensile-resistant portion 931 located between the crimping ring 911 and the outer sheath 920 can also protect the optical fiber and electronic wire in the cable 900 and prevent the optical fiber and electronic wire from being crushed.

Optionally, the cable 900 further has an optical fiber layer 950, a middle quilt 960 and an electronic wire layer 970, the middle quilt 960 wraps the optical fiber layer 950, the electronic wire layer 970 is arranged outside the middle quilt 960, the anti-drawing layer 930 is arranged outside the electronic wire layer 970, the shielding layer 940 is arranged outside the anti-drawing layer 930, and the outer sheath 920 is arranged outside the shielding layer 940.

[0057] In this embodiment, the outer sheath 920 is sleeved on the outside of the first shielding part, and the second shielding part 941 exceeds the left end of the outer sheath 920. The second shielding part 941 can be bent to the right to cover a part of the outer surface of the outer sheath 920. After the second shielding part 941 is folded out, the contact area between the shielding layer 940 and the electromagnetic shielding shell can be increased, thereby increasing the stability of the electrical connection between the shielding layer 940 and the electromagnetic shielding shell. In addition, the second deformation part is a conductive structure, which is electrically connected to the housing 100, and after the cable 900 is inserted into the housing 100, the clamping part 720 clamps the second shielding part 941 of the cable 900, so that the shielding layer 940 of the cable 900 can be electrically connected to the housing 100 through the elastic clamping member 700, so that the electromagnetic waves conducted in the shielding layer 940 of the cable 900 can be conducted to the housing 100 through the elastic clamping member 700, and then conducted to the ground through the connection seat connected to the connector, thereby preventing the electromagnetic waves conducted in the shielding layer 940 of the cable 900 from electromagnetically interfering with the electrical components in the housing 100. Further, a conductive gasket 850 is provided between the second shielding part 941 and the clamping part 720, so that the clamping part 720 can better electrically contact the second shielding part 941.

[0058] In an optional embodiment, the cable 900 has an outer sheath 920 and a shielding layer 940, and the shielding layer 940 is provided with an anti-pull wire 942 extending along the axial direction of the cable 900.
