Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a housing and an electrical connector. Background Technology

[0002] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and power distribution cabinets) to downstream devices. They are often used to distribute main power to server racks.

[0003] Existing electrical connectors typically penetrate the rear panel of a server rack and plug into and electrically connect to rack bus assemblies within the rack. The 2022 Open Rack V3 Connector specification reveals that the connector utilizes locking bumps to prevent accidental disengagement in the insertion direction. However, the connector is prone to sliding in the direction perpendicular to the insertion direction, making it easy for the locking bumps to detach from the rear panel of the server rack. Utility Model Content

[0004] The main purpose of this invention is to propose a housing and an electrical connector, which aims to limit the housing in the length direction, making the connection between the electrical connector and the server rack more stable and preventing the electrical connection between the two from failing.

[0005] To achieve the above objectives, the present invention proposes a housing for an electrical connector. The housing includes a base, at least two protrusions, a positioning protrusion, and a connecting rod. The base has two perpendicularly arranged sections in a length direction, a width direction, and a height direction. The base has a receiving cavity. One surface of the base extends outward from opposite sides in the length direction to form a wing, and one of the wing sections has a clearance opening. At least two protrusions are disposed on the surface of the base where the wing sections are formed. The at least two protrusions extend along the height direction, and each protrusion has a slot extending along the height direction, which communicates with the receiving cavity. The positioning protrusion is movably inserted through the clearance opening along the height direction. One end of the positioning protrusion has a locked state exposed in the clearance opening in the height direction and an unlocked state retracted in the clearance opening in the height direction. The connecting rod is movably connected to the base, and one end of the connecting rod drives the other end of the positioning protrusion to switch between the locked state and the unlocked state.

[0006] In one embodiment, the middle part of the connecting rod is provided with a rotating shaft facing the base, and the side surface of the base is provided with a shaft hole. The rotating shaft is inserted into and rotatably connected to the shaft hole. One end of the connecting rod is provided with a connecting shaft facing the positioning protrusion, and the other end of the positioning protrusion is provided with a connecting hole. The connecting shaft is inserted into and rotatably connected to the connecting hole.

[0007] In one embodiment, there are two positioning protrusions, and each of the two wings has a clearance opening, with one positioning protrusion movably passing through one of the clearance openings;

[0008] The number of connecting rods is two, and the two connecting rods are rotatably connected to the opposite sides of the base in the length direction. One end of one connecting rod is driven to connect to the other end of the positioning protrusion.

[0009] In one embodiment, the housing further includes a connecting beam extending along the length direction, with both ends of the connecting beam connected to the other ends of the two connecting rods, respectively.

[0010] In one embodiment, the base has a boss on one surface in the width direction, and an elastic element is provided between the connecting beam and the boss, the elastic element being used to push the connecting beam away from the boss.

[0011] In one embodiment, the connecting beam has a guide post on the surface facing the boss, the boss has a groove on the surface facing the connecting beam, one end of the elastic member is sleeved on the guide post, and the other end of the elastic member abuts against the bottom of the groove.

[0012] In one embodiment, the housing further includes a pull ring that is slidable along a surface of the base in the width direction. One side of the pull ring is connected to the connecting beam, and driving the other side of the pull ring causes the connecting beam, the connecting rod, and the positioning protrusion to move.

[0013] In one embodiment, the base has a limiting portion on one surface in the width direction, and the inner wall of the other side of the pull ring can be engaged with the limiting portion to prevent the elastic element from resetting.

[0014] In one embodiment, a pull part is provided on the other side of the pull ring, and the pull part extends along the width direction.

[0015] This utility model also proposes an electrical connector, which includes a housing, a terminal module and a conductive module as described above. The terminal module is disposed in the receiving cavity of the housing and protrudes from the slot. One end of the conductive module is electrically connected to the terminal module, and the other end of the conductive module is exposed in the housing.

[0016] The technical solution of this utility model employs a positioning protrusion that movably passes through a clearance opening on the wing of the base. The positioning protrusion has a locked state exposed in the clearance opening and an unlocked state retracted into the clearance opening. When the positioning protrusion is in the locked state, if the housing needs to move in the longitudinal direction relative to the rear panel, the positioning protrusion will abut against the housing, acting as a limit to prevent the housing from detaching from the rear panel of the server rack. To facilitate switching the state of the positioning protrusion, a linkage is provided to drive and connect the positioning protrusion for user operation. Attached Figure Description

[0030] Electrical connectors are typically used at the power output end. They are interface components that transmit electrical energy from power modules (such as uninterruptible power supplies, battery packs, and power distribution cabinets) to downstream devices. They are often used to distribute main power to server racks.

[0031] Existing electrical connectors typically penetrate the rear panel of a server rack and plug into and electrically connect to rack bus assemblies within the rack. The 2022 Open Rack V3 Connector specification reveals that the connector utilizes locking bumps to prevent accidental disengagement in the insertion direction. However, the connector is prone to sliding in the direction perpendicular to the insertion direction, making it easy for the locking bumps to detach from the rear panel of the server rack.

[0032] This invention proposes a housing and an electrical connector, which aims to limit the housing in the length direction to make the connection between the electrical connector and the server rack more stable and prevent the electrical connection between the two from failing.

[0033] Please see Figures 1 to 3 In one embodiment of this utility model, the housing 10 is used for an electrical connector 100. The housing 10 includes a base 1, at least two protrusions 3, positioning protrusions 4, and connecting rods 5. The base 1 has two perpendicularly arranged length directions, width directions, and height directions. The base 1 has a receiving cavity. One surface of the base 1 extends outward on opposite sides in the length direction to form a wing 2. One wing 2 has a clearance opening 21. At least two protrusions 3 are provided on the surface of the base 1 where the wing 2 is formed. The at least two protrusions 3 extend along the height direction. Extending in the direction, each protrusion 3 is provided with a slot 31 extending in the height direction, and the slot 31 communicates with the receiving cavity; the positioning protrusion 4 is movably inserted through the clearance opening 21 in the height direction, and one end of the positioning protrusion 4 has a locked state exposed in the clearance opening 21 in the height direction and an unlocked state retracted in the clearance opening 21 in the height direction; the connecting rod 5 is movably connected to the base 1, and one end of the connecting rod 5 drives the other end of the positioning protrusion 4 so that one end of the positioning protrusion 4 switches between the locked state and the unlocked state.

[0034] In this embodiment, the base 1 is the main structure of the housing 10, and can be made of injection-molded high-strength plastic. The accommodating cavity is an internal hollow structure used to arrange the positioning protrusion 4 or to pass through the terminal module 20 and the conductive module 30. The clearance opening 21 is a through hole opened in the wing 2 on the surface of the base 1. Its size is slightly larger than the range of motion of the positioning protrusion 4, allowing the positioning protrusion 4 to slide along the edge of the clearance opening 21 to switch positions. The protrusion 3 refers to the docking structure extending from the surface of the base 1. Its slot 31 is a through channel, which can be integrally molded with the base 1. It is used to fix the terminal module 20 and establish the insertion path with the rack. The connecting rod 5 is a structure used to drive the positioning protrusion 4 to switch states. The connecting rod 5 is driven to the positioning protrusion 4. After insertion, the driving connecting rod 5 drives the positioning protrusion 4 to switch to the locked state to prevent the housing 10 from moving to the position of the release hole in the first direction, thereby falling off the back panel of the server rack and causing a power outage.

[0035] The technical solution of this utility model employs a positioning protrusion 4 that is movably inserted through a clearance opening 21 on the wing 2 of the base 1. The positioning protrusion 4 has a locked state exposed in the clearance opening 21 and an unlocked state retracted into the clearance opening 21. When the positioning protrusion 4 is in the locked state, if the housing 10 needs to move in the length direction relative to the rear panel, the positioning protrusion 4 will abut against the housing 10, acting as a limit to prevent the housing 10 from detaching from the rear panel of the server rack. To facilitate switching the state of the positioning protrusion 4, a connecting rod 5 is provided to drive and connect the positioning protrusion 4 for user operation.

[0036] In an embodiment of this utility model, a rotating shaft 51 is provided on the side of the middle part of the connecting rod 5 facing the base 1. A shaft hole is opened on the side surface of the base 1. The rotating shaft 51 is inserted into and rotatably connected to the shaft hole. A connecting shaft 52 is provided on the side of one end of the connecting rod 5 facing the positioning protrusion 4. A connecting hole is opened on the other end of the positioning protrusion 4. The connecting shaft 52 is inserted into and rotatably connected to the connecting hole.

[0037] In this embodiment, a rotating shaft 51 is provided in the middle of the connecting rod 5. The rotating shaft 51 is a cylindrical structure integrally formed with the connecting rod 5, used to cooperate with the shaft hole of the base 1 to form a rotation fulcrum. The shaft hole is a circular hole opened on the side surface of the base 1, which can be processed by drilling or injection molding, used to accommodate the rotating shaft 51 and allow the connecting rod 5 to rotate around its axis. The connecting shaft 52 is a cylindrical structure set at one end of the connecting rod 5, which can be made of the same material and process as the rotating shaft 51, used to insert into the connecting hole of the positioning protrusion 4 and convert the rotational motion of the connecting rod 5 into the linear motion of the positioning protrusion 4. The connecting hole is a circular hole opened at the other end of the positioning protrusion 4, which can be processed by drilling or injection molding, used to accommodate the connecting shaft 52 and allow it to rotate, thereby transmitting the rotational motion of the connecting rod 5 to the positioning protrusion 4. When the connecting rod 5 rotates around the rotating shaft 51, the connecting shaft 52 rotates in the connecting hole and pushes the positioning protrusion 4 to move along the height direction, thereby realizing the switching between the locked state and the unlocked state. The engagement between the rotating shaft 51 and the shaft hole ensures stable rotation of the connecting rod 5, preventing deviation or jamming; the engagement between the connecting shaft 52 and the connecting hole converts rotation into linear motion, ensuring accurate movement of the positioning protrusion 4.

[0038] In an embodiment of this utility model, there are two positioning protrusions 4, and each of the two wings 2 has a clearance opening 21, with one positioning protrusion 4 movably passing through one clearance opening 21.

[0039] There are two connecting rods 5. The two connecting rods 5 are rotatably connected to the opposite sides of the base 1 in the length direction. One end of one connecting rod 5 is driven to connect to the other end of a positioning protrusion 4.

[0040] In this embodiment, the wings 2 on both sides of the base 1 along its length are respectively provided with clearance openings 21, and two positioning protrusions 4 are each inserted into the corresponding clearance opening 21. Two connecting rods 5 are respectively installed on both sides of the base 1 along its length and are rotatably connected to the base 1 through a rotating shaft 51. When the connecting rod 5 is operated, it rotates around the rotating shaft 51, driving the connecting shaft 52 to move, thereby driving the positioning protrusions 4 to move along the height direction within the clearance opening 21. The positioning protrusions 4 and connecting rods 5 symmetrically arranged on both sides can effectively limit the housing 10 on both sides along its length, preventing the housing 10 from moving along its length and causing unilateral detachment at the detachment opening.

[0041] In an embodiment of this utility model, the housing 10 further includes a connecting beam 6, which extends along the length direction, and both ends of the connecting beam 6 are respectively connected to the other ends of the two connecting rods 5.

[0042] In this embodiment, both ends of the connecting beam 6 are fixedly connected to the free ends of the connecting rods 5 on both sides. When an external force is applied to the connecting beam 6, the connecting beam 6 translates or rotates along its length, causing the connecting rods 5 on both sides to rotate synchronously around their respective axes of rotation 51, thereby driving the positioning protrusions 4 on both sides to switch between locked and unlocked states. Through the linkage design of the connecting beam 6, the movements of the positioning protrusions 4 on both sides are forced to be synchronized, avoiding positioning failure or structural jamming due to unilateral operation.

[0043] Please see Figure 1 and Figure 3 In an embodiment of this utility model, a boss 11 is provided on one surface of the base 1 in the width direction, and an elastic member 7 is provided between the connecting beam 6 and the boss 11. The elastic member 7 is used to push the connecting beam 6 away from the boss 11.

[0044] In this embodiment, a boss 11 is provided on one surface of the base 1 in the width direction. An elastic element 7 is disposed between the connecting beam 6 and the boss 11. The boss 11 provides a support surface for the elastic element 7. The elastic element 7 is a mechanical element with elastic deformation capability, which can be implemented by a compression spring or an elastic rubber column. The reaction force generated by the deformation pushes the connecting beam 6 to move and reset, thereby switching the state of the positioning protrusion 4 to the unlocked state. When an external force is applied to the connecting beam 6 and it moves close to the boss 11, the elastic element 7 is compressed and accumulates elastic potential energy. When the external force is released, the elastic element 7 releases the potential energy to push the connecting beam 6 to reset, thereby driving the connecting rod 5 to rotate and driving the positioning protrusion 4 to switch to the unlocked state.

[0045] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment of the present invention, the surface of the connecting beam 6 facing the boss 11 is provided with a guide post 53, the surface of the boss 11 facing the connecting beam 6 is provided with a groove 111, one end of the elastic member 7 is sleeved on the guide post 53, and the other end of the elastic member 7 abuts against the bottom of the groove 111.

[0046] In this embodiment, the elastic element 7 is compressed between the guide post 53 and the groove 111. The guide post 53 is inserted into the inner hole of one end of the elastic element 7 to limit lateral displacement, and the other end of the elastic element 7 is embedded in the bottom of the groove 111 to maintain axial alignment. When the connecting beam 6 is subjected to external force and moves closer to the boss 11, the elastic element 7 is compressed along the direction of the guide post 53. After the external force is released, the elastic element 7 pushes the connecting beam 6 away from the boss 11, thereby driving the connecting rod 5 to switch the state of the positioning boss 4. The cooperation between the guide post 53 and the groove 111 ensures that the elastic element 7 maintains stable alignment during repeated compression, preventing the movement of the elastic element 7 from becoming skewed.

[0047] In an embodiment of this utility model, the housing 10 further includes a pull ring 8, which can slide along a surface of the base 1 in the width direction. One side of the pull ring 8 is connected to the connecting beam 6, and the other side of the pull ring 8 is driven to move the connecting beam 6, the connecting rod 5 and the positioning protrusion 4.

[0048] In this embodiment, when the positioning protrusion 4 needs to be pushed out of the base 1, the operator pulls the other side of the pull ring 8 along the height direction of the base 1. The pull ring 8 drives the connecting beam 6 to move closer to the protrusion 11. The displacement of the connecting beam 6 is transmitted to the positioning protrusion 4 through the connecting rod 5, forcing the positioning protrusion 4 to rise along the height direction and be exposed outside the clearance opening 21. At this time, the positioning protrusion 4 is in a locked state, and the housing 10 can be limited by the positioning protrusion 4 in the first direction, preventing it from sliding to the release hole and detaching from the server's rear panel. When the pull ring 8 is released, the elastic element 7 pushes the connecting beam 6 to reset, and the connecting rod 5 rotates in the opposite direction and drives the positioning protrusion 4 to retract into the clearance opening 21, restoring the unlocked state. The synchronous control of the positioning protrusion 4 can be achieved by the unidirectional sliding of the pull ring 8, avoiding mechanism jamming due to incorrect operation direction.

[0049] In an embodiment of this utility model, a limiting part 12 is provided on one surface of the base 1 in the width direction, and the inner wall of the other side of the pull ring 8 can be locked in the limiting part 12 to prevent the elastic element 7 from resetting.

[0050] In this embodiment, when the positioning protrusion 4 needs to be pushed out of the base 1, the operator pulls the other side of the pull ring 8 along the height direction of the base 1. The pull ring 8 drives the connecting beam 6 to move closer to the protrusion 11. The displacement of the connecting beam 6 is transmitted to the positioning protrusion 4 through the connecting rod 5, forcing the positioning protrusion 4 to rise along the height direction and be exposed outside the clearance opening 21. At this time, the positioning protrusion 4 is in a locked state, and the housing 10 can be limited by the positioning protrusion 4 in the first direction to prevent it from sliding to the release hole and detaching from the server rear panel. The inner wall of the other side of the pull ring 8 is stuck on the limiting part 12, and the elastic element 7 cannot recover its deformation, thereby keeping the positioning protrusion 4 exposed outside the clearance opening 21. The limiting part 12 can free the operator's hands and keep the positioning protrusion 4 in a locked state at all times. When unlocking is required, the pull ring 8 is removed from the limiting part 12, the elastic element 7 returns to its original shape, pushes the connecting beam 6, drives the pull rod to rotate downward, and finally drives the positioning protrusion 4 to retract into the clearance opening 21, switching to the unlocked state. At this time, the housing 10 can be moved in the first direction, aligned with the release hole, and the housing 10 can be detached from the server rear panel from the third direction.

[0051] In an embodiment of this utility model, a pull part 81 is provided on the other side of the pull ring 8, and the pull part 81 extends along the width direction.

[0052] In this embodiment, the pull part 81 is a part for manual operation by the user, which can be implemented using a raised or recessed structure, such as a transverse raised strip or groove 111 on the surface of the pull ring 8. This structure allows the fingers to naturally conform to the force applied, preventing slippage during operation. The width direction of the pull part 81 extends parallel to the width direction of the base 1, which can be achieved by designing the pull part 81 as a long strip with its axis coinciding with the width direction of the base 1. This directional design ensures that the direction of the pulling force applied by the user is completely consistent with the sliding direction of the pull ring 8, reducing the impact of lateral force on operation.

[0053] Please see Figure 3 , Figure 5 and Figure 6 The present invention also proposes an electrical connector 100, which includes a housing 10, a terminal module 20 and a conductive module 30 as described above. The terminal module 20 is disposed in the receiving cavity of the housing 10 and protrudes from the slot 31. One end of the conductive module 30 is electrically connected to the terminal module 20, and the other end of the conductive module 30 is exposed in the housing 10.

[0054] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope 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 patent protection scope of the present utility model.
