[0002] One end of the wire connector is connected to the power supply, and the other end is usually equipped with a connector for plugging into and electrically connecting to the board connector in the appliance to supply power to the appliance.

[0003] The connection direction of the two insertion holes of existing wire connectors is usually set perpendicular to the direction of the cable exit, which is not conducive to layout and routing. Utility Model Content

[0004] The main purpose of this utility model is to provide a wire-end connector and connector assembly, which aims to make the connection between the first through hole and the second through hole parallel to the outgoing direction of the cable, so as to facilitate the layout and routing of the cable.

[0005] To achieve the above objectives, the present invention proposes a wire connector comprising a housing, two terminal modules, two cables, and a cover. The housing has an open receiving cavity, the bottom of which is provided with a partition platform that divides the receiving cavity into a first receiving cavity and a second receiving cavity. The bottom of the receiving cavity has a first through hole and a second through hole, the first through hole communicating with the first receiving cavity and the second through hole communicating with the second receiving cavity. One side wall of the receiving cavity has a first clearance opening and a second clearance opening. The two terminal modules are respectively partially inserted through the first through hole and the second through hole. The two cables pass through the first clearance opening and the second clearance opening respectively and are electrically connected to the two terminal modules respectively. The line connecting the center of the first through hole and the center of the second through hole is parallel to the outgoing direction of the two cables. The cover is closed and connected to the opening.

[0006] In one embodiment, the partition platform includes at least one bend, and the first receiving cavity includes at least one bend.

[0007] In one embodiment, the housing includes a main body and a protrusion. The main body has an opening in the receiving cavity. The protrusion is connected to the surface of the main body opposite to the opening. A first through hole and a second through hole are provided in the protrusion and communicate with the receiving cavity.

[0008] In one embodiment, the ratio between the thickness of the main body and the thickness of the shell is greater than or equal to 0.4 and less than or equal to 0.6.

[0009] In one embodiment, each terminal module includes a conductive block and an annular terminal.

The annular terminal is disposed in the countersunk hole. The other end of the conductive block is electrically connected to the cable, and the extension directions of the other ends of the two conductive blocks are perpendicular.

[0010] In one embodiment, the cover has two protrusions on its surface facing the housing. When the cover is closed on the opening of the housing, one of the protrusions abuts against a conductive block in the first through hole or the second through hole.

[0011] In one embodiment, the wire connector further includes a latch, which is rotatably connected to the surface of the housing opposite to the first clearance opening. The latch is located on the straight line between the first through hole and the second through hole, and is used to engage with the board connector.

[0012] In one embodiment, the housing has a protruding boss, and the cover has a third through hole.

One end of the driven member is connected to the hook, and the driving member is rotatably connected to the boss. The driving member drives the other end of the driven member to move the hook away from the housing.

[0013] In one embodiment, the cover and the housing are connected by screws and buckles. The cover has multiple through holes and multiple screws. Each screw passes through the through holes and is fixed in multiple fixing slots. Each fixing slot is distributed on the top surface of the main body on both sides of the first receiving cavity. The cover partition platform has at least two cover fixing slots. The two opposite side walls of the main body have buckle holes. The cover has multiple barbed buckles. The multiple buckles and buckle holes match to fix the cover to the housing.

[0014] This utility model also proposes a connector assembly, which includes a wire-end connector and a board-end connector as described above. The board-end connector includes a housing and a terminal assembly disposed within the housing. The housing is plugged into the housing, and the terminal assembly is electrically connected to the terminal module.

[0015] The technical solution of this utility model divides the accommodating cavity into a first accommodating cavity and a second accommodating cavity by using a partitioning platform. The first accommodating cavity and the second accommodating cavity are respectively provided with a first through hole and a second through hole, as well as a first clearance opening and a second clearance opening. Terminal modules are provided in the first through hole and the second through hole. The first clearance opening and the second clearance opening are used for cable passing through.

[0031] One end of the wire connector is connected to the power supply, and the other end is usually equipped with a connector for plugging into and electrically connecting to the board connector in the appliance to supply power to the appliance.

[0032] The connection direction of the two insertion holes of existing wire connectors is usually set perpendicular to the direction of the cable exit, which is not conducive to layout and routing.

[0033] This utility model proposes a wire-end connector and connector element, designed to make the connection between the first through hole and the second through hole parallel to the outgoing direction of the cable, facilitating cable routing. Parallel outgoing direction means that the outgoing directions of the two cables extend in substantially the same or similar directions.

[0034] Please see Figures 1 to 7 In one embodiment of this utility model, the wire connector 10 includes a housing 11, two end sub-modules 12, two cables 13, and a cover 14. The housing 11 has an open receiving cavity 111. The bottom of the receiving cavity 111 is provided with a dividing platform 1121, which divides the receiving cavity 111 into a first receiving cavity 1111 and a second receiving cavity 1112. The bottom of the receiving cavity 111 has a first through hole 1131 and a second through hole 1132. The first through hole 1131 communicates with the first receiving cavity 1111, and the second through hole... 1132 is connected to the second receiving cavity 1112. The cavity wall of the receiving cavity 111 has a first clearance opening 1122 and a second clearance opening 1123. The two end sub-modules 12 are respectively partially inserted through the first through hole 1131 and the second through hole 1132. The two cables 13 pass through the first clearance opening 1122 and the second clearance opening 1123 respectively, and are electrically connected to the two end sub-modules 12 respectively. The line connecting the center of the first through hole 1131 and the center of the second through hole 1132 is parallel to the outgoing direction of the two cables 13. The cover 14 is closed and connected to the opening.

[0035] In this embodiment, the receiving cavity 111 is a cavity inside the housing 11 used to accommodate the terminal module 12 and the cable 13 connection structure. Specifically, it can be formed into an upward-facing cavity structure through injection molding for easy assembly. The partition platform 1121 is a partition structure set at the bottom of the cavity. It can be a vertical or inclined plate structure to divide the receiving cavity 111 into two independent areas to avoid mutual interference between the terminal modules 12. The first through hole 1131 and the second through hole 1132 are channels penetrating the bottom of the cavity. Their positions are determined according to the cable 13's outgoing direction. For example, they can be symmetrically distributed along the length of the housing 11 to ensure that the center line of the through holes is consistent with the extension direction of the cable 13. The first clearance opening 1122 and the second clearance opening 1123 are openings formed on the side wall of the receiving cavity 111 for the cable 13 to pass through and connect to the terminal module 12. Their shape can be rectangular or arc-shaped to avoid wear on the cable 13's outer sheath. The terminal module 12 is a conductive connection component and can be a metal stamping part. One end is inserted into the through hole to achieve external connection, and the other end is welded or crimped to the cable 13. The cover 14 is a closed component that covers the opening of the housing 11 and can be fixed by buckles or screws to prevent the internal structure from loosening.

[0036] The interior of the housing 11 is divided into two independent receiving cavities 111 by a partition platform 1121. Each receiving cavity 111 corresponds to a set of through holes and clearance openings. The terminal module 12 is partially inserted into the through hole, and the cable 13 passes through the clearance opening and connects to the terminal module 12. Since the center line of the through hole is parallel to the exit direction of the cable 13, the cable 13 can extend in the same direction without bending, reducing space occupation. After the cover 14 is closed, it presses the terminal module 12 to ensure connection stability. For example, when installed inside a power cabinet, the cable 13 can be directly arranged parallel to the inner wall of the equipment to avoid interference with other components.

[0037] The technical solution of this utility model divides the receiving cavity 111 into a first receiving cavity 1111 and a second receiving cavity 1112 by using a partition platform 1121. The first receiving cavity 1111 and the second receiving cavity 1112 are respectively provided with a first through hole 1131 and a second through hole 1132, as well as a first clearance opening 1122 and a second clearance opening 1123. Terminal modules 12 are provided in the first through hole 1131 and the second through hole 1132. The first clearance opening 1122 and the second clearance opening 1123 are used to pass through cables 13. The connection direction of the first through hole 1131 and the second through hole 1132 is the same as the outgoing direction of the cable 13, which reduces the installation space requirement and simplifies the wiring path.

[0038] In an embodiment of the present invention, the partition platform 1121 includes at least one bend, and the first receiving cavity 1111 includes at least one bend.

[0039] In this embodiment, the L-shaped partition platform 1121 is a plate-like structure with two mutually perpendicular extensions. Specifically, it can be integrally formed with the housing 11 using injection molding. Its vertical extensions can form the isolation boundary between adjacent receiving cavities 111. The L-shaped first receiving cavity 1111 is a cavity structure with two vertically extending spaces formed by the L-shaped partition platform 1121 and the cavity wall of the receiving cavity 111. Specifically, it can be achieved by adjusting the bending angle and length of the partition platform 1121, and its shape matches the routing of the cable 13 and the layout of the terminal module 12.

[0040] In an embodiment of the present invention, the housing 11 includes a main body 112 and a protrusion 113. The main body 112 has an opening in the receiving cavity 111. The protrusion 113 is connected to the surface of the main body 112 away from the opening. A first through hole 1131 and a second through hole 1132 are provided in the protrusion 113 and communicate with the receiving cavity 111.

[0041] In this embodiment, the main body 112 forms the basic structure of the housing 11. Specifically, it can be formed into an open cavity structure using injection molding to support the terminal module 12 and the cable 13. The protrusion 113 is a partial structure extending from the main body 112. It can be fixed to the back of the main body 112 by integral molding or separate assembly, and is used to provide through holes and enhance the support strength of the housing 11. The first through hole 1131 and the second through hole 1132 are channel structures that penetrate the protrusion 113. They can be processed by drilling or mold forming processes, and are used to guide the terminal module 12 to extend to the outside of the receiving cavity 111. The protrusion 113 is used for plug-in connection with the board-end connector 20, improving the connection strength between the wire-end connector 10 and the board-end connector 20. Furthermore, the thickness of the main body 112 can be reduced to decrease the installation space requirement.

[0042] In an embodiment of this utility model, the ratio between the thickness of the main body 112 and the thickness of the shell 11 is greater than or equal to 0.4 and less than or equal to 0.6.

[0043] In this embodiment, the main body 112 serves as the supporting component of the receiving cavity 111, and its thickness directly affects the fixing effect on the cable 13 and the terminal module 12. When the ratio of the thickness of the main body 112 to the thickness of the housing 11 is in the range of 0.4 to 0.6, such as 0.4, 0.5, 0.6 or any value within the above range, the main body 112 can provide sufficient support for the receiving cavity 111 while avoiding redundancy in the overall size of the housing 11 due to excessive thickness of the main body 112.

[0044] In an embodiment of this utility model, each terminal module 12 includes a conductive block 121 and an annular terminal 122. One end of the conductive block 121 passes through the first through hole 1131 or the second through hole 1132. A countersunk hole is formed at one end of the conductive block 121, and the annular terminal 122 is disposed in the countersunk hole. The other end of the conductive block 121 is electrically connected to the cable 13, and the extension directions of the other ends of the two conductive blocks 121 are perpendicular.

[0045] In this embodiment, the conductive block 121 is a metal structure for conducting current, specifically made of copper or copper alloy, and its shape can be cuboid or cylindrical to achieve stable current transmission. The annular terminal 122 is a connecting component with an annular contact surface, specifically made of elastic metal sheet wound into an annular structure to enhance the contact reliability with the board-end connector 20. The countersunk hole is a recessed structure formed at the end of the conductive block 121, specifically formed by drilling or stamping, used to fix the annular terminal 122 and limit its displacement. The perpendicular extension direction means that the ends of the two conductive blocks 121 extend in mutually perpendicular directions to accommodate the L-shaped first receiving cavity 1111 and the straight second receiving cavity 1112, thereby ensuring that the outgoing directions of the two cables 13 are the same. This can be achieved by adjusting the installation angle of the conductive blocks 121 to optimize the cable 13 layout space.

[0046] In an embodiment of this utility model, the surface of the cover 14 facing the housing 11 is provided with two protrusions 141. When the cover 14 is closed on the opening of the housing 11, one protrusion 141 abuts against a conductive block 121 at the first through hole 1131 or the second through hole 1132.

[0047] In this embodiment, after the cover 14 is closed, the protrusions 141 on its surface contact the conductive blocks 121 in the first through hole 1131 and the second through hole 1132, respectively. Through the abutment action of the protrusions 141 against the conductive blocks 121, the axial position of the conductive blocks 121 in the through holes is fixed, preventing the connection between the conductive blocks 121 and the cable 13 from becoming loose due to external force or vibration.

[0048] In an embodiment of this utility model, the wire connector 10 further includes a hook 15, which is rotatably connected to the surface of the housing 11 away from the first clearance opening 1122. The hook 15 is located on the straight line where the first through hole 1131 and the second through hole 1132 are located, and the hook 15 is used to engage with the board connector 20.

[0049] In this embodiment, the hook 15 is a hook-shaped structure with elastic deformation capability, which can be implemented by metal stamping or injection molding. The hook part and the corresponding structure of the plate end connector 20 form a mechanical interlock. The rotational connection is achieved by the relative rotation between the hook 15 and the housing 11 through a shaft hole fit or a hinge structure. Specifically, it can be achieved by the fit of a rotating shaft and a bushing, so that the hook 15 can swing around a fixed axis.

[0050] In an embodiment of this utility model, the housing 11 is provided with a boss 114, and the cover 14 is provided with a third through hole 142. When the cover 14 is closed on the housing 11, the boss 114 passes through the third through hole 142 and is exposed on the cover 14.

[0051] The wire connector 10 also includes an active member 16 and a passive member 17. One end of the passive member 17 is connected to the hook 15, and the active member 16 is rotatably connected to the boss 114. The active member 16 drives the other end of the passive member 17 to move the hook 15 away from the housing 11.

[0052] In this embodiment, when the cover 14 is closed on the housing 11, the boss 114 on the housing 11 passes through the third through hole 142 of the cover 14. At this time, the active member 16 is installed on the exposed part of the boss 114 through a rotating shaft structure. When it is necessary to release the engagement between the hook 15 and the board end connector 20, the active member 16 is operated to rotate around the boss 114. The rotational movement of the active member 16 is transmitted to the driven member 17 through a linkage mechanism. The other end of the driven member 17 drives the hook 15 to generate a displacement away from the housing 11, thereby realizing the rapid separation of the hook 15 from the board end connector 20.

[0053] In an embodiment of this utility model, the cover 14 is connected to the housing 11 by screws and buckles. The cover 14 is provided with multiple through holes and multiple screws. Each screw passes through the through holes and is fixed in multiple fixing grooves. Each fixing groove is distributed on the top surface of the main body 112 on both sides of the first receiving cavity 1111111. The cover partition platform 1121 is provided with at least two cover fixing grooves. The two opposite side walls of the main body 112 are provided with buckle holes. The cover 14 is provided with multiple barbed buckles. The multiple buckles and buckle holes match to fix the cover 14 to the housing 11.

[0054] In this embodiment, the connection method between the cover 14 and the housing 11 can be selected according to actual needs, using screws alone, snap fasteners alone, or a combination of both. For example, in scenarios requiring frequent disassembly, a snap fastener structure is preferred to achieve quick assembly and disassembly; in scenarios requiring high stability, screws are preferred for fixing; if both convenience and reliability are required, snap fasteners can be symmetrically arranged on both sides of the housing 11, and a screw hole can be added at the center of the cover 14 for reinforcement with screws.

[0055] Please see Figure 8 The present invention also proposes a connector assembly 100, which includes a wire-end connector 10 and a board-end connector 20 as described above. The board-end connector 20 includes a housing 21 and a terminal assembly 22 disposed in the housing 21. The housing 21 is plugged into the housing 11, and the terminal assembly 22 is electrically connected to the terminal module 12.

[0056] 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.
