SUMMARY

[0003] In order to overcome the deficiencies in the prior art, the utility model provides a kind of connector, its connector body is installed in the installation window of connector fixed frame, and active gap is formed between the two, so that the connector body can be moved relative to the connector fixed frame, to be able to compensate the error between equipment and equipment, after the plug-in of connector body and mating connector, equipment cooperation error will not cause adverse effect to the connection of shear force;Sealing portion is further provided on the connector body, and first sealing element is provided between the sealing portion and the connector fixed frame, so that the connector has good waterproof and sealing effect.The utility model further provides a kind of connector assembly.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions to realize:

[0005] A kind of connector, for being electrically connected with mating connector, comprising:

[0006] Connector fixed frame, the connector fixed frame has installation window;

[0007] And connector body, the connector body is arranged in the installation window, and the opposite part of the installation window inner wall in the outer wall of the connector body is formed as mating outer wall, and at least active gap is formed between the mating outer wall and the installation window inner wall in one direction perpendicular to the axis of the installation window, the sealing portion is formed on the side of the mating outer wall and is outwardly convex in the circumferential direction, and the sealing portion can completely cover the installation window, first sealing element is arranged between the sealing portion and the connector fixed frame, and the first sealing element is arranged around the installation window;Specifically, the first sealing element adopts sealing ring.

[0008] Using the above technical scheme, when used, the connector is installed on the equipment through the connector fixed frame, the mating connector is installed on another equipment, and the electrical connection between the connector and the mating connector is realized to connect the equipment.

[0009] Since the active gap is formed between the mating outer wall of the connector body and the inner wall of the mounting window in at least one direction perpendicular to the axis of the mounting window, i.e., the connector body can move relative to the connector fixed frame in the direction with the active gap, when the connector body is electrically connected with the mating connector, if there is an error between the mounting position of the connector on the device and the mounting position of the mating connector on another device, and the error direction is consistent with the direction in which the active gap is formed between the mating outer wall of the connector body and the inner wall of the mounting window, the connector body can move relative to the connector fixed frame to compensate for the mating error between the devices, so that the connector body and the mating connector can be more stably and reliably electrically connected, and can avoid bearing shear force when they are mated, for example, to avoid bending of the pins and other adverse conditions.

[0010] And due to the arrangement of the sealing part and the first sealing element, the outer periphery of the mounting window can be sealed, and external liquid entering the device through the gap between the mounting window and the connector body can be prevented.

[0011] The above technical solution can not only avoid the influence of shear force on the connector and the mating connector when they are mated, but also has good waterproof performance during long-term use.

[0012] In some embodiments, the cross section of the connector body is substantially rectangular, the mounting window is substantially rectangular, and the width of the cross section of the connector body matches the width of the mounting window, and the length of the cross section of the connector body is smaller than the length of the mounting window, i.e., the active gap exists between the mating outer wall of the connector body and the inner wall of the mounting window in the length direction of the cross section. The above structure can enable the movement of the connector body to compensate for the error in the length direction of the cross section of the connector body when the devices are mated.

[0013] In some embodiments, the cross section of the connector body is circular, the mounting window is substantially circular, i.e., the shape of a rectangle with semicircles on both sides, and the diameter of the cross section of the connector body matches the width of the mounting window, and the diameter of the cross section of the connector body is smaller than the length of the mounting window, i.e., the active gap exists between the mating outer wall of the connector body and the inner wall of the mounting window in the length direction of the cross section. The above structure can enable the movement of the connector body to compensate for the error in the length direction of the cross section of the connector body when the devices are mated.

[0014] The error direction between the installation position of the connector on the device and the installation position of the mating connector on another device is uncontrollable during the production and installation process;

[0015] Further, in some embodiments, the mating outer wall and the installation window inner wall form a movable gap in any direction perpendicular to the installation window axis.

[0016] With the above technical solution, the connector body can move in any direction perpendicular to the installation window axis relative to the connector fixed frame, so that the movement of the connector body can compensate for the error between the installation position of the connector on the device and the installation position of the mating connector on another device in any direction perpendicular to the installation window axis. The above technical solution makes the connector more practical and can cope with more use cases.

[0017] Specifically, in some embodiments, the cross section of the connector body is approximately rectangular, the installation window is approximately rectangular, and the width of the cross section of the connector body is less than the width of the installation window, and the length of the cross section of the connector body is less than the length of the installation window. The above structure realizes that the mating outer wall and the installation window inner wall form a movable gap in any direction perpendicular to the installation window axis.

[0018] In some embodiments, the cross section of the connector body is circular, the installation window is circular, and the diameter of the cross section of the connector body is less than the diameter of the installation window. The above structure realizes that the mating outer wall and the installation window inner wall form a movable gap in any direction perpendicular to the installation window axis.

[0019] Further, the connector fixed frame is recessed around the installation window on the outside of the installation window to form a first seal mounting groove matched with the first seal. The first seal is mounted in the first seal mounting groove, and the side of the first seal away from the bottom of the first seal mounting groove protrudes out of the first seal mounting groove.

[0020] With the above technical solution, the installation of the first seal is more stable and less likely to displace, greatly enhancing the sealing effect during use.

[0021] Further, the first seal mounting groove is recessed outward in its width direction to form a first seal positioning groove, and the first seal is protruded outward in its width direction to form a first seal positioning part matched with the first seal positioning groove.

[0022] Specifically, the first sealing member positioning grooves are provided in plurality, and the plurality of first sealing member positioning grooves are arranged at intervals along the circumferential direction of the first sealing member mounting groove; the first sealing member positioning portions are provided in plurality, and the distribution positions of the plurality of first sealing member positioning portions correspond to the distribution positions of the plurality of first sealing member positioning grooves one by one.

[0023] By the above technical solution, the first sealing member positioning grooves cooperate with the first sealing member positioning portions to position and mount the first sealing member, and the mounting of the first sealing member is more stable and less likely to displace, thereby greatly enhancing the sealing effect in use.

[0024] Further, the connector body is outwardly protruded at the other side of the matching outer wall to form a limiting protrusion, and the distance between the end of the limiting protrusion away from the connector body and the side of the limiting protrusion toward the connector body is greater than the maximum movable gap between the mounting window and the connector body at the position corresponding to the limiting protrusion; the distance between the side of the limiting protrusion toward the sealing portion and the side of the sealing portion toward the limiting protrusion is matched with the height of the mounting window to enable the sealing portion to press the first sealing member.

[0025] By the above technical solution, the limiting protrusion makes the connector more reasonable, and the cooperation between the limiting protrusion and the sealing portion can limit the movement of the connector body relative to the connector fixed frame in the axial direction, and enables the connector body and the connector fixed frame to be mounted together to avoid separation and facilitate actual use.

[0026] The cooperation between the limiting protrusion and the sealing portion also enables the sealing portion to stably and reliably press the first sealing member to ensure the sealing effect between the sealing portion and the first sealing member.

[0027] Of course, in some embodiments, the limiting protrusion can not be provided, but this requires that a corresponding structure be provided to act as the limiting protrusion when the connector is mounted on a device.

[0028] Further, the limiting protrusion is provided in plurality, and the plurality of limiting protrusions are distributed at intervals in the circumferential direction of the connector body.

[0029] By the above technical solution, the plurality of limiting protrusions can better cooperate with the sealing portion, and the sealing portion can better seal with the first sealing member; and the mounting between the connector body and the connector fixed frame can be more stable and reliable.

[0030] Further, two ends of the connector body are formed as a first electrical connection end and a second electrical connection end, respectively, the first electrical connection end is used for electrical connection with the mating connector, and the second electrical connection end is used for connection with a wire in the device.

[0031] The sealing part is arranged on one side of the matching outer wall towards the first electrical connection end, and the limiting protrusion is arranged on one side of the matching outer wall towards the second electrical connection end.

[0032] The above technical solution makes the connector body more reasonable, and the arrangement of the sealing part and the limiting protrusion is more reasonable.

[0033] Further, one side of the connector fixing frame towards the second electrical connection end is provided with a second sealing member, and the second sealing member is used for sealing the gap between the connector fixing frame and the device.

[0034] The above technical solution provides the second sealing member, so that the connector fixing frame and the device have a sealing effect, preventing liquid from entering through the gap between the connector fixing frame and the device; specifically, the second sealing member is a sealing pad capable of covering one side of the connector fixing frame towards the second electrical connection end.

[0035] Further, the connector body includes a connector main body and a connector cover body, two ends of the connector main body are formed as the first electrical connection end and the second electrical connection end, respectively, the matching outer wall is formed on the connector main body, the sealing part is arranged on the connector main body, the connector cover body is arranged on the second electrical connection end, and an outer wall of the connector cover body is outwardly protruded to form the limiting protrusion.

[0036] The above technical solution makes the connector body more reasonable, facilitating the installation between the connector body and the connector fixing frame; specifically, a user can first pass the second electrical connection end of the connector main body through the mounting window of the connector fixing frame, and then install the connector cover on the second electrical connection end, to realize the installation therebetween.

[0037] Further, the connector main body is provided with a first cover body mounting structure at the second electrical connection end, and the connector cover body is provided with a second cover body mounting structure fixedly connected and matched with the first cover body mounting structure.

[0038] The above technical solution realizes the installation between the connector cover body and the second electrical connection end through the cooperation of the first cover body mounting structure and the second cover body mounting structure.

[0039] Further, the first cover mounting structure is arranged on the outer side wall of the second electrical connection end, the connection cover side wall is located outside the outer side wall of the second electrical connection end, and the second cover mounting structure is arranged or formed at the position opposite to the first cover mounting structure in the connection cover side wall.

[0040] The above technical solution makes the arrangement of the first cover mounting structure and the second cover mounting structure more reasonable, and facilitates the cooperation and installation therebetween.

[0041] Further, one of the first cover mounting structure and the second cover mounting structure is configured as a buckle protrusion, the other of the first cover mounting structure and the second cover mounting structure is configured as an elastic buckle matched with the buckle protrusion, and the elastic buckle is provided with a buckle slot capable of allowing the buckle protrusion to be buckled.

[0042] The above technical solution makes the arrangement of the first cover mounting structure and the second cover mounting structure more reasonable, and the buckle protrusion and the elastic buckle can be more quickly assembled, and the installation is stable and reliable. Specifically, the first cover mounting structure is configured as the buckle protrusion, and the second cover mounting structure is configured as the elastic buckle.

[0043] Further, the buckle protrusion is provided with a buckle guide surface for guiding the elastic buckle to deform when the connector cover is mounted to the second electrical connection end, so that the buckle protrusion is buckled into the buckle slot.

[0044] The arrangement of the buckle guide surface can make the buckle protrusion contact the elastic buckle when the connector cover is mounted to the second electrical connection end. Under the action of the buckle guide surface, the elastic buckle deforms until the buckle protrusion is opposite to the buckle slot, the elastic buckle resets, and the elastic buckle is automatically buckled into the buckle slot. The above mounting operation is convenient and fast. Specifically, the buckle guide surface adopts an inclined surface or an arc surface.

[0045] Further, one end of the connector body is formed as a first electrical connection end for electrical connection with the mating connector, one end of the mating connector is formed as a third electrical connection end for electrical cooperation with the first electrical connection end, and the first electrical connection end and the third electrical connection end are in plug-in cooperation.

[0046] The above technical solution makes the arrangement of the connector body more reasonable, and the connection between the connector body and the mating connector is more convenient.

[0047] Further, the third electrical connection end comprises an electrical connection peripheral wall matched with the first electrical connection end, the first electrical connection end is inserted in the electrical connection peripheral wall, and a third sealing element is arranged between the first electrical connection end and the electrical connection peripheral wall, in particular, the third sealing element is a sealing ring.

[0048] By adopting the technical scheme, the third sealing element is arranged, so that the sealing effect is achieved between the first electrical connection end of the connector body and the third electrical connection end of the matched connector when they are plugged and matched.

[0049] Further, the outer side wall of the first electrical connection end is inwardly recessed to form a third sealing element mounting groove, the third sealing element mounting groove is arranged around the outer side wall of the first electrical connection end and matched with the third sealing element, the third sealing element is mounted in the third sealing element mounting groove, and the side of the third sealing element away from the groove bottom of the third sealing element mounting groove protrudes out of the third sealing element mounting groove.

[0050] By adopting the technical scheme, the third sealing element mounting groove is arranged, so that the third sealing element is more stable in mounting and is less likely to displace, and the sealing effect in use is greatly enhanced.

[0051] Further, the third sealing element mounting groove is outwardly recessed in the width direction to form a third sealing element positioning groove, and the third sealing element is outwardly protruded in the width direction to form a third sealing element positioning part matched with the third sealing element positioning groove.

[0052] In particular, the third sealing element positioning groove is provided with a plurality of third sealing element positioning grooves, and the plurality of third sealing element positioning grooves are arranged at intervals along the surrounding direction of the third sealing element mounting groove, the third sealing element positioning part is provided with a plurality of third sealing element positioning parts, and the distribution positions of the plurality of third sealing element positioning parts correspond to and match the distribution positions of the plurality of third sealing element positioning grooves.

[0053] By adopting the technical scheme, the third sealing element positioning groove and the third sealing element positioning part are matched to position and mount the third sealing element, so that the third sealing element is more stable in mounting and is less likely to displace, and the sealing effect in use is greatly enhanced.

[0054] Further, the matched connector is provided with a guide column.

[0055] The sealing part of the connector body is provided with a connector body guide hole matched with the guide column at the outer side in sealing contact with the first sealing element.

[0056] The connector has a more reasonable structure, and when the connector is inserted into the mating connector, the guide post enters the guide hole of the connector body, thereby guiding the connector body to face the mating connector to realize the normal insertion of the two, avoiding the influence of shear force between the two, and the structure can realize blind insertion during installation, thereby facilitating actual use.

[0057] Further, the connector fixing frame is provided with a frame guide groove outside the sealing contact position of the first sealing element, the diameter of the frame guide groove matches the diameter of the guide post, or the frame guide groove and the guide post have a matching gap, and the matching gap between the frame guide groove and the guide post matches the movable gap between the mating outer wall and the inner wall of the mounting window.

[0058] In the state that the frame guide groove and the guide post have a matching gap, the sealing part can cover the mounting window when the connector body moves relative to the connector fixing frame and always sealingly contacts the first sealing element.

[0059] The connector is fixedly installed on a device, and the mating connector is installed on another device, and errors may exist between the two, when the diameter of the frame guide groove matches the diameter of the guide post, the connector and the mating connector are inserted into each other, the guide post is matched with the guide hole of the connector body, at this time, the connector body moves relative to the connector fixing frame to realize the normal insertion between the connector body and the mating connector, and after the guide post passes through the guide hole of the connector body and is matched with the frame guide groove, at this time, the guide post acts on the frame guide groove, so that the connector fixing frame moves, that is, the device on which the connector is installed moves, to realize the position correction between the two devices, after correction, the connector body and the connector fixing frame are still coaxially arranged, so as not to affect the sealing effect of the first sealing element.

[0060] When the frame guide slot and the guide post have a matching gap, the connector and the mating connector are in the plug-in matching state, the guide post matches the connector body guide hole at this time, and the connector body moves relative to the connector fixed frame to realize the positive plug-in connection between the connector body and the mating connector. When the guide post passes through the connector body guide hole and matches the frame guide slot, since the matching gap between the frame guide slot and the guide post matches the movable gap between the matching outer wall and the mounting window inner wall, the guide post directly enters the frame guide slot and does not act on the frame guide slot to make the connector fixed frame move, that is, the device mounting the connector does not move, and the position between the two devices is not corrected. And since the coverage of the sealing part can ensure that the mounting window can be covered and the first sealing member can be in sealing contact when the connector body moves relative to the connector fixed frame, the sealing reliability between the two is ensured.

[0061] Specifically, in the state that the diameter of the frame guide slot matches the diameter of the guide post, the sealing part satisfies that the mounting window can be covered and the first sealing member can be in sealing contact when the connector body moves relative to the connector fixed frame; and the sealing effect of the first sealing member can be ensured in any case.

[0062] Further, a first guide surface for guiding the guide post into the connector body guide hole is formed on the side of the connector body guide hole away from the connector fixed frame.

[0063] The side of the frame guide slot away from the sealing part is formed with a second guide surface for guiding the guide post into the frame guide slot.

[0064] By adopting the above technical solution, the first guide surface and the second guide surface are arranged, which is beneficial to the insertion of the guide post into the connector body guide hole and the frame guide slot during the plug-in process of the connector and the mating connector.

[0065] Further, the insertion end of the guide post is conical.

[0066] By adopting the above technical solution, the insertion of the guide post is facilitated.

[0067] Further, along the radial inward direction of the connector body guide hole, the first guide surface gradually inclines to the side of the connector fixed frame;

[0068] Along the radial inward direction of the frame guide slot hole, the second guide surface gradually inclines to the side away from the sealing part.

[0069] The first guide surface and the second guide surface are more reasonable in structure.

[0070] The connector assembly comprises the connector and a mating connector electrically connected with the connector.

[0071] The connector body and the mating connector can be electrically connected more stably and reliably, and can avoid being subjected to shear force when being matched, for example, avoiding the bending of the pin and other adverse conditions.

[0072] Further, the mating connector comprises a mating connector body and a mating connector fixing frame surrounding the mating connector body, and the mating connector fixing frame is used for being fixed with the equipment.

[0073] The fourth seal is arranged on the side of the mating connector fixing frame away from the connector, and is used for sealing the gap between the mating connector fixing frame and the equipment.

[0074] Further, the connector is a socket, and the mating connector is a plug.

[0097] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0098] Referring to Figures 1 to 9 The present application provides a kind of connector 100, it is used to be electrically connected with mating connector 200, comprising:

[0099] The connector fixed frame 1, the connector fixed frame 1 has installation window 101;

[0100] And a connector body 2 is arranged in the mounting window 101, and the part of the outer wall of the connector body 2 opposite to the inner wall of the mounting window 101 is formed as a matching outer wall 201, and at least in one direction perpendicular to the axis of the mounting window 101, a movable gap 3 is formed between the matching outer wall 201 and the inner wall of the mounting window 101, and the connector body 2 is protruded outward in the circumferential direction on one side of the matching outer wall 201 to form a sealing part 202, and the sealing part 202 can completely cover the mounting window 101, and a first sealing element 4 is arranged between the sealing part 202 and the connector fixing frame 1, and the first sealing element 4 is arranged around the mounting window 101; specifically, the first sealing element 4 is a sealing ring.

[0101] By using the above technical scheme, when in use, the connector 100 is mounted on a device through the connector fixing frame, the matching connector 200 is mounted on another device, and the electrical connection between the connector 100 and the matching connector 200 is achieved to realize the connection between the devices.

[0102] Since the matching outer wall 201 of the connector body 2 and the inner wall of the mounting window 101 form a movable gap 3 at least in one direction perpendicular to the axis of the mounting window 101, that is, the connector body 2 can move relative to the connector fixing frame 1 in the direction with the movable gap 3, when the connector body 2 is electrically connected with the matching connector 200, if there is an error between the mounting position of the connector 100 on the device and the mounting position of the matching connector 200 on the other device, and the error direction is consistent with the direction in which the movable gap 3 is formed between the matching outer wall 201 of the connector body 2 and the inner wall of the mounting window 101, the connector body 2 can move relative to the connector fixing frame 1 to compensate for the matching error between the devices, so that the connector body 2 and the matching connector 200 can be more stably and reliably electrically connected and matched, and when they are matched, the shear force can be avoided, for example, the bending of the pin and other adverse conditions can be avoided.

[0103] And due to the arrangement of the sealing part 202 and the first sealing element 4, the outer periphery of the mounting window 101 can be sealed, and external liquid can enter the device through the gap between the mounting window 101 and the connector body 2.

[0104] The above technical scheme not only can avoid the influence of shear force on the connector 100 and the matching connector 200 in the plug-in state, but also has good waterproof performance in the long-term use process.

[0105] In some embodiments, the connector body 2 has a substantially rectangular cross section, the mounting window 101 has a substantially rectangular shape, and the width of the cross section of the connector body 2 matches the width of the mounting window 101, and the length of the cross section of the connector body 2 is smaller than the length of the mounting window 101, that is, there is the clearance 3 between the mating outer wall 201 of the connector body 2 and the inner wall of the mounting window 101 in the length direction of the cross section; the above structure can make the movement of the connector body 2 compensate for the error in the length direction of the cross section of the connector body 2 when the equipment is matched.

[0106] In some embodiments, the cross section of the connector body 2 is circular, the mounting window 101 has a substantially circular shape, that is, a shape with a rectangular middle and half-circular sides, and the diameter of the cross section of the connector body 2 matches the width of the mounting window 101, and the diameter of the cross section of the connector body 2 is smaller than the length of the mounting window 101, that is, there is the clearance 3 between the mating outer wall 201 of the connector body 2 and the inner wall of the mounting window 101 in the length direction of the cross section; the above structure can make the movement of the connector body 2 compensate for the error in the length direction of the cross section of the connector body 2 when the equipment is matched.

[0107] Since the error direction between the mounting position of the connector 100 on the equipment and the mounting position of the mating connector 200 on another equipment is uncontrollable during the production and installation process;

[0108] Further, in some embodiments, the clearance 3 is formed between the mating outer wall 201 and the inner wall of the mounting window 101 in any direction perpendicular to the axis of the mounting window 101.
