The extension direction of the protrusion is defined as a third direction. The button module is movably inserted through the first clearance opening. The button module has a first state protruding from the first clearance opening and a second state retracting into the first clearance opening. When the protrusion is inserted into the server rack, the button module is in the first state, thereby limiting the housing to the server rack in the first and second directions.

[0006] In one embodiment, the button module includes an active member and a passive member. One end of the passive member is movably disposed through the first clearance opening. The passive member has a first state and a second state. The active member is movably disposed in the receiving cavity and connected to the other end of the passive member, driving the active member to switch one end of the passive member between the first state and the second state.

[0007] The cavity has an opening at the bottom, and the housing also includes a cover plate that is detachably connected to the edge of the opening to limit the button module within the cavity.

[0008] In one embodiment, a second clearance opening is provided on one side wall of the receiving cavity, and the second clearance opening communicates with the first clearance opening;

[0009] The driven member includes a first part and a second part connected to each other. The first part is movably disposed through the first clearance opening, and the second part is exposed in the second clearance opening. The driving member is movably disposed in the receiving cavity in the third direction, and is partially exposed in the second clearance opening, and is located between the second part and a cavity wall of the receiving cavity.

[0010] The active component is driven to move in the third direction, thereby causing the driven component to switch between the first state and the second state.

[0011] In one embodiment, the second clearance opening is provided with a first limiting groove and a second limiting groove spaced apart on both inner sides of the first direction. The first limiting groove and the second limiting groove extend along the second direction. The two ends of the first limiting groove and the second limiting groove are open. The active member is provided with limiting portions protruding on both sides. One of the limiting portions can be locked in a first limiting groove or a second limiting groove.

[0012] The limiting part is engaged in the first limiting groove, and the driven member is in the first state;

[0013] The limiting part is engaged in the second limiting groove, and the driven member is in the second state.

[0014] In one embodiment, the first limiting groove and the second limiting groove are fitted together;

[0015] When the active member is driven to move along the second direction and the third direction, and the limiting part moves from the first limiting groove to the second limiting groove, the active member drives the driven member to switch to the second state.

[0016] When the active member is driven to move along the second direction and the third direction, and the limiting part moves from the second limiting groove to the first limiting groove, the active member drives the driven member to switch to the first state.

[0017] In one embodiment, an elastic member is provided between the active member and the first portion, the elastic member being used to push the active member to expose itself in the second clearance opening in the second direction.

[0018] In one embodiment, a surface of the base has a protrusion on the side of the protrusion opposite to the first clearance opening, the protrusion being used to limit the housing in the first direction and the second direction.

[0019] In one embodiment, a baffle is provided on one side of the protrusion in the second direction, the baffle extends along the second direction, and a slot is formed between the baffle and a surface of the base. The slot is used to clamp the rear panel of the server rack, and the baffle is used to limit the housing in the third direction.

[0020] In one embodiment, there are two baffles, which are respectively disposed on opposite sides of the protrusion.

[0021] This utility model also proposes an electrical connector, including a housing, a terminal module and a conductive module as described above. The terminal module is disposed in a slot 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.

[0022] The housing in this invention is used for an electrical connector and includes a base, a protrusion, and a button module. The protrusion is located on one surface of the base and has a slot with two through-holes. A terminal module passes through and is exposed in the slot. The button module is movably inserted through a first clearance opening in the base. The button module has a first state exposed on one surface of the base and a second state retracted into the base. The protrusion is used to insert into the server rack to electrically connect the terminal module to the rack busbar. Switching the button module to the first state exposes it on one surface of the base. When the housing moves relative to the server rack, the protruding part of the button module abuts against the rear panel of the server to limit the relative movement between the two in the first and second directions, making the connection between the electrical connector and the server rack more stable and preventing electrical connection failure.

[0036] 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.

[0037] Existing electrical connectors typically penetrate the rear panel of the server rack and plug into the rack bus assembly inside the rack for electrical connection. This plug-in connection method is prone to loosening over time, potentially causing the electrical connection between the connector and the server rack to fail.

[0038] This invention proposes a housing and an electrical connector, which aims to make the connection between the electrical connector and the server rack more stable and prevent the electrical connection between the two from failing.

[0039] Please see Figures 1 to 6 In one embodiment of this utility model, the housing 10 is used for an electrical connector 100. The housing 10 includes a base 11, a protrusion 12, and a button module 13. The base 11 has a receiving cavity, and a first clearance opening 111 communicating with the receiving cavity is opened on one surface of the base 11. The length direction of the base 11 is defined as a first direction, and the width direction of the base 11 is defined as a second direction. The protrusion 12 is disposed on one surface of the base 11 and located on one side of the first clearance opening 111. The protrusion 12 is used for insertion into a server rack. 2 has a slot 121, one end of which is connected to the receiving cavity. The slot 121 is used to insert and expose the terminal module 20. The extension direction of the protrusion 12 is defined as the third direction. The button module 13 is movably inserted into the first clearance opening 111. The button module 13 has a first state protruding from the first clearance opening 111 and a second state retracting into the first clearance opening 111. When the protrusion 12 is inserted into the server rack, the button module 13 is in the first state to limit the housing 10 in the server rack in the first and second directions.

[0040] In this embodiment, the base 11 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 button module 13 or to pass through the terminal module 20 and conductive module. The first clearance opening 111 refers to a through hole opened on the surface of the base 11, the size of which is slightly larger than the range of motion of the button module 13, allowing the button module 13 to switch positions. The protrusion 12 refers to the mating structure extending from the surface of the base 11, the slot 121 of which is a through channel, which can be integrally molded with the base 11, and is used to fix the terminal module 20 and establish a plug-in path with the cabinet. The button module 13 refers to an operating mechanism containing mechanical linkage components, and can be a spring-returned slider structure, which forms a constraint by contacting the inner wall of the cabinet through a physical limiting surface.

[0041] Specifically, when the protrusion 12 is inserted into the server rack, the button module 13 is protruded by the internal mechanism. At this time, the exposed part of the button module 13 forms line contact with the panel of the server rack in the first and second directions, restricting the displacement of the housing 10 along the first and second directions.

[0042] Compared to existing technologies, traditional electrical connectors 100 rely solely on the friction of the mating structure to maintain connection, which cannot withstand multi-directional external forces. This solution utilizes a switchable button module 13 to provide active positioning, with the button module 13 abutting against the rear panel of the server rack in both the first and second directions. Compared to single-sided snap-fit ​​or threaded fixing solutions, this design eliminates the need for additional fasteners, achieving multi-dimensional positioning through the structure of the housing 10 itself. Furthermore, the switching between the protruding and retracted states of the button module 13 makes installation and disassembly operations more convenient, avoiding the risk of damage from tool operations in traditional solutions.

[0043] The housing 10 of this utility model is used for the electrical connector 100 and includes a base 11, a protrusion 12, and a button module 13. The protrusion 12 is disposed on one surface of the base 11 and has a slot 121 through both ends. The terminal module 20 passes through and is exposed in the slot 121. The button module 13 is movably inserted through a first clearance opening 111 of the base 11. The button module 13 has a first state exposed on one surface of the base 11 and a second state retracted into the base 11. The protrusion 12 is used to insert into the server rack so that the terminal module 20 is electrically connected to the rack bus. Switching the button module 13 to the first state exposes the button module 13 on one surface of the base 11. When the housing 10 moves relative to the server rack, the protruding part of the button module 13 abuts against the rear panel of the server to limit the relative movement between the two in the first and second directions, making the connection between the electrical connector 100 and the server rack more stable and preventing the electrical connection between the two from failing.

[0044] In an embodiment of this utility model, the button module 13 includes an active member 131 and a passive member 132. One end of the passive member 132 is movably disposed through the first clearance opening 111. The passive member 132 has a first state and a second state. The active member 131 is movably disposed in the receiving cavity and connected to the other end of the passive member 132. The active member 131 drives the passive member 132 to switch between the first state and the second state.

[0045] The cavity has an opening at the bottom, and the housing 10 also includes a cover plate 14, which is detachably connected to the edge of the opening to limit the button module 13 within the cavity.

[0046] In this embodiment, the active member 131 refers to an operating component that can move within the receiving cavity, specifically implemented as a sliding block or push rod structure. Its function is to transmit driving force to the driven member 132 through its own movement. The driven member 132 refers to an actuating component that is linked with the active member 131, specifically implemented as a connecting rod or slider structure. Its function is to convert the movement of the active member 131 into an extension and retraction action at its end, realizing the switching between the first state and the second state. The connection between the active member 131 and the driven member 132 can be implemented using a hinge, snap-fit, or sliding groove engagement method, which ensures the reliability of motion transmission and the controllability of direction. The bottom of the receiving cavity has an opening, and a cover plate 14 is detachably connected to the edge of the opening to limit the button module 13 within the receiving cavity. Through the detachable connection of the cover plate 14, the internal button module 13 can be replaced.

[0047] In one example, the specific connection between the active member 131 and the driven member 132 is as follows: the active member 131 has a hook protruding from its surface facing the driven member 132, and the second part 1322 of the driven member 132 has a slot on its surface facing the active member 131. Through the cooperation of the hook and the slot, the hook can slide along the slot in a third direction, so that the active member 131 slides relative to the first part 1321 of the driven member 132 in a third direction. The hook moves towards the server rack in the third direction, driving the driven member 132 to move towards the server rack in the third direction, thereby switching the driven member 132 from the second state to the first state.

[0048] In an embodiment of this utility model, a second clearance opening 112 is provided on one side wall of the receiving cavity, and the second clearance opening 112 is connected to the first clearance opening 111.

[0049] The driven member 132 includes a first part 1321 and a second part 1322 connected to each other. The first part 1321 is movably disposed through the first clearance opening 111, and the second part 1322 is exposed in the second clearance opening 112. The driving member 131 is movably disposed in the receiving cavity in a third direction, and is partially exposed in the second clearance opening 112, and is located between the second part 1322 and a cavity wall of the receiving cavity.

[0050] The driving active component 131 moves in a third direction to drive the driven component 132 to switch between a first state and a second state.

[0051] In this embodiment, the second clearance opening 112 is an opening structure formed on the side wall of the receiving cavity, which can be achieved by stamping or cutting. Its function is to provide a space for movement and a support interface for the second part 1322 of the driven member 132. The first part 1321 and the second part 1322 are two parts of the driven member 132, which can be achieved by integral molding or separate assembly. The first part 1321 is used to perform the limiting function, and the second part 1322 is used to transmit the driving force. The positional relationship of the driving member 131 between the second part 1322 and the cavity wall can be achieved by a slide rail or guide groove structure. Its function is to convert the linear motion in the third direction into the state switching action of the driven member 132.

[0052] In a preferred embodiment, the first part 1321 and the second part 1322 of the driven member 132 are connected at right angles, and the second clearance opening 112 is opened on the side wall, which can avoid the power connection line and prevent the connection line from blocking the drive member 131.

[0053] In one example, the base 11 is a plate-shaped structure. The receiving cavity is formed by three side walls connected end to end and a cover fastened to the three side walls and the other surface of the base 11. The opening formed by the enclosure is the second clearance opening 112. The active member 131 and the driven member 132 are movably disposed in the receiving cavity. The cover plays a limiting role to prevent the active member 131 from moving too much and causing it to detach from the receiving cavity.

[0054] In an embodiment of this utility model, the second clearance opening 112 is provided with a first limiting groove 1121 and a second limiting groove 1122 spaced apart on the two inner sides of opposite sides in the first direction. The first limiting groove 1121 and the second limiting groove 1122 extend along the second direction. The two ends of the first limiting groove 1121 and the second limiting groove 1122 are open. The active member 131 is provided with limiting parts 1311 protruding on opposite sides. A limiting part 1311 can be locked in a first limiting groove 1121 or a second limiting groove 1122.

[0055] The limiting part 1311 is engaged in the first limiting groove 1121, and the follower 132 is in the first state;

[0056] The limiting part 1311 is engaged in the second limiting groove 1122, and the follower 132 is in the second state.

[0057] In this embodiment, the first limiting groove 1121 and the second limiting groove 1122 are groove structures provided on both sides of the second clearance opening 112. Specifically, they can be formed by milling into two parallel straight grooves, which provide a sliding track for the limiting part 1311 through their extension features along the second direction. The limiting part 1311 is a protrusion structure provided on both sides of the active member 131. Specifically, it can be formed by injection molding into rectangular protrusions that match the width of the limiting grooves. The active member 131 is mechanically locked in position by engaging with the limiting grooves at different positions. The limiting groove structure with openings at both ends allows the limiting part 1311 to slide freely in the second direction, while the extension direction of the groove restricts the movement trajectory of the limiting part 1311 in the third direction. In a preferred embodiment, a vertical sliding groove arranged along a third direction is connected between the first limiting groove 1121 and the second limiting groove 1122. A C-shaped sliding groove is formed between the first limiting groove 1121, the vertical sliding groove, and the second limiting groove 1122. The limiting part 1311 can slide along the C-shaped sliding groove to slide between the first limiting groove 1121 and the second limiting groove 1122.

[0058] In an embodiment of this utility model, the first limiting groove 1121 and the second limiting groove 1122 are fitted together;

[0059] When the driving member 131 moves along the second direction and the third direction, and the limiting part 1311 moves from the first limiting groove 1121 to the second limiting groove 1122, the driving member 131 drives the driven member 132 to switch to the second state.

[0060] When the driving member 131 moves along the second direction and the third direction, and the limiting part 1311 moves from the second limiting groove 1122 to the first limiting groove 1121, the driving member 131 drives the driven member 132 to switch to the first state.

[0061] In this embodiment, the fitting arrangement of the first limiting groove 1121 and the second limiting groove 1122 means that the two sets of limiting grooves are arranged side by side along the second direction and share a groove wall, so that when the limiting part 1311 moves, it only needs to make a slight displacement along the third direction to complete the switching between grooves, thus shortening the operation stroke.

[0062] In an embodiment of this utility model, an elastic member 133 is provided between the active member 131 and the first part 1321. The elastic member 133 is used to push the active member 131 to be exposed in the second clearance opening 112 in the second direction.

[0063] In this embodiment, the elastic element 133 can be a helical spring, an elastic rubber block, or a sheet, which stores energy and releases pushing force through elastic deformation. When the active element 131 is exposed in the second clearance opening 112, the elastic element 133 is in a state of no force. When the active element 131 is pushed in the second direction, the elastic element 133 is compressed by external force. After releasing, the elastic element 133 restores its deformation and pushes the active element 131 out of the second clearance opening 112, preventing the housing 10 from becoming loose due to the button module 13 failing to reset, ensuring that the engagement between the active element 131 and the limiting groove is always in the preset state, and improving the installation stability and electrical connection reliability of the housing 10 in the server rack.

[0064] In one example, the active member 131 and the passive member 132 of the button module 13 are stacked on top of each other in a third-order upward manner. An elastic member 133 is provided between the first part 1321 of the active member 131 and the passive member 132. The second part 1322 of the active member 131 and the passive member 132 are slidably connected. A guide post may be provided on the active member 131, and the elastic member 133 passes through the guide post to stabilize the deformation of the elastic member 133.

[0065] In an embodiment of the present invention, a protrusion 113 is provided on one surface of the base 11 on the other side of the protrusion 12 opposite to the first clearance opening 111. The protrusion 113 is used to limit the housing 10 in the server rack in the first direction and the second direction.

[0066] In this embodiment, when the housing 10 is inserted into the mounting hole of the server rack, the protrusion 113 and the button module 13 are located on opposite sides of the mounting hole. After the adjacent two sides of the protrusion 113 contact the inner wall of the mounting hole, they directly prevent the housing 10 from displacing in the first and second directions. The protrusion 113, through a bidirectional limiting fit with the button module 13, eliminates the displacement degree of freedom of the housing 10 in the orthogonal plane, thereby avoiding loosening of the connection due to vibration or insertion / removal force.

[0067] In an embodiment of the present invention, a baffle 122 is provided on one side of the protrusion 12 in the second direction. The baffle 122 extends along the second direction, and a slot is formed between the baffle 122 and a surface of the base 11. The slot is used to clamp the rear panel of the server rack, and the baffle 122 is used to limit the housing 10 in the server rack in the third direction.

[0068] In this embodiment, when the housing 10 is inserted into the server rack, the rear panel is clamped by the slot. The gap formed between the baffle 122 and the surface of the base 11 restricts the movement of the rear panel in the second direction. At the same time, the extension structure of the baffle 122 in the third direction directly prevents the housing 10 from displacing in the insertion and removal direction. The length of the baffle 122 covers the contact area between the rear panel and the housing 10, thereby increasing the clamping stability by increasing the contact area. The depth of the slot matches the height of the baffle 122, ensuring that the rear panel will not come out of the constraint during the clamping process.

[0069] In an embodiment of this utility model, there are two baffles 122, which are respectively disposed on opposite sides of the protrusion 12.

[0070] In this embodiment, two baffles 122 are located on both sides of the protrusion 12 in the second direction. When the housing 10 is inserted into the server rack, the edge of the rear panel of the server rack is engaged in the slots formed by the two baffles 122 and the surface of the base 11. Because the two baffles 122 are symmetrically distributed, the clamping force is evenly applied to both sides of the rear panel, avoiding tilting or loosening caused by unilateral force. In the third direction, the two baffles 122 simultaneously form a bidirectional limit on the rear panel, restricting the front-to-back displacement of the housing 10 in the third direction, ensuring the connection stability between the housing 10 and the server rack.

[0071] This utility model also proposes an electrical connector 100 including a housing 10, a terminal module 20 and a conductive module as described above. The terminal module 20 is disposed in a slot 121 of the housing 10 and protrudes from the slot 121. One end of the conductive module is electrically connected to the terminal module 20, and the other end of the conductive module is exposed in the housing 10.

[0072] 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.
