[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 distribution cabinets) to downstream devices. They are commonly used to distribute main power to various electrical devices.

[0037] In the prior art, in order to prevent users from accidentally disassembling the wire-end connector and the board-end connector, in addition to fasteners on both sides of the wire-end connector to fasten it to the board-end connector, screws are also used to lock the wire-end connector to the PCB board, but the screws are inconvenient to remove.

[0038] This utility model proposes a wire-end connector, a board-end connector, and a connector assembly, designed to prevent users from accidentally removing the connector.

[0039] Please see Figures 1 to 10 In one embodiment of this utility model, the wire connector 10 includes a housing 1, a plurality of first terminal modules 2, two fasteners 3, and a pin 4. The housing 1 includes a base 11 and a plurality of protrusions 12, which are spaced apart on one surface of the base 11. The housing 1 has a plurality of parallel first through holes 13 and a second through hole 14. The first through hole 13 passes through a protrusion 12 and the base 11, and the second through hole 14 passes through the base 11. Each first terminal module 2 passes through a first through hole 13. Each fastener 3 is movably disposed on one side wall of the base 11, and one end of each fastener 3 is exposed on one surface of the base 11. The pin 4 is movably disposed in the second through hole 14. The pin 4 can move along the axial direction of the second through hole 14 and rotate along the circumferential direction of the second through hole 14. The pin 4 has a locked state exposed in the second through hole 14 and an unlocked state retracted in the second through hole 14.

[0040] In this embodiment, the electrical connector is used for the wire end. The outer shell 1 is made of insulating material, such as hard plastic or hard rubber, to prevent current leakage through the outer shell 1 and causing short circuits or other problems. The outer shell 1 includes a base 11 and multiple protrusions 12. The base 11 and the multiple protrusions 12 can be integrally formed by injection molding or connected as a whole by bonding or ultrasonic welding, etc., without further limitation. When the connector needs to be fixed, the pin 4 is pushed to move axially along the second through hole 14 to the exposed position, and then rotated at a certain angle to switch the pin 4 to the locked state and engage with the board end connector 20. The protrusion 12 and the board end connector 20 are inserted to form the first repositioning, the fastener 3 and the hook 8 are engaged to form the second fixing, and the pin 4 is locked to form the third mechanical locking, which improves the connection strength between the wire end connector 10 and the board end connector 20.

[0041] The first terminal module 2 is a tubular structure with a through-hole inside. It can be made of copper or aluminum, etc. The first terminal module 2 passes through the first through-hole 13. The connection between the first terminal module 2 and the wall of the first through-hole 13 can be a snap-fit ​​connection or a plug-in connection. An insulating post passes through the cavity of the first terminal module 2 and connects to the cavity wall. Furthermore, one end of the insulating post is detachably connected to the cavity wall, which can be a threaded connection or a plug-in connection. The insulating post is made of insulating material such as silicone or rubber to prevent accidental electric shock. One end of the insulating post connects to the cavity wall, thus dividing the cavity within the first terminal module 2 into a first cavity and a second cavity. The other end of the insulating post extends from the cavity wall towards the opening of the first cavity, which is used to insert another electrical connector. A ring-shaped terminal is located on the cavity wall of the first cavity. The second cavity is used to solder electrical connection wires to achieve current input or output. The first through hole 13 has an opening on one side for inserting another electrical connector. The end face of the first terminal module 2 facing the opening is provided with an insulating element. The insulating element is a ring structure made of insulating material, such as a silicone ring or a rubber ring, to prevent electric shock caused by accidental contact with the end face of the tubular metal terminal.

[0042] The electrical connector has a U-shaped baffle on one side wall of the base 11, and a fastener 3 that is rotatably connected to the two side plates of the U-shaped baffle. One end of the fastener 3 is exposed on a surface of the base 11 where the protrusion 12 is located, for engaging with another electrical connector to enhance the connection strength between the two connectors and prevent accidental disconnection that could cause electrical connection failure. The fastener 3 is connected to the two side plates of the U-shaped baffle via a shaft hole fit, allowing the fastener 3 to rotate relative to the U-shaped baffle, thereby achieving the effect of engaging and disengaging with the other electrical connector.

[0043] In the technical solution of this utility model, the wire-end connector 10, based on the plug-in connection and the two-button fastening connection, is provided with a pin 4 having a locked state and an unlocked state. When the wire-end connector 10 is connected to the board-end connector 20, the pin 4 is driven to switch to the locked state. The pin 4 can be locked inside the board-end connector 20. At this time, the wire-end connector 10 and the board-end connector 20 will not be disconnected by external force or by opening the fastener 3, thus improving the connection stability between the two.

[0044] In an embodiment of this utility model, the pin 4 includes a column 41 and an extension 42. The column 41 is movably inserted through the second through hole 14, and the extension 42 is disposed at one end of the column 41 and extends outward along the radial direction of the column 41. The extension 42 is used to engage with the board end connector 20.

[0045] In this embodiment, the column 41 is a cylindrical or prismatic main structure, which can be made of metal or rigid plastic. It is used to transmit axial and circumferential motion forces, while ensuring the stable movement and rotation of the pin 4 within the second through hole 14. The extension 42 is a protrusion or snap-fit ​​structure that extends outward from the end of the column 41 along its circumference. It can be made of a sheet-like, hook-like, or plate-like component integrally formed with the column 41. It is used to engage with the corresponding structure of the plate-end connector 20 and restrict the displacement of the pin 4 in the locked state.

[0046] In an embodiment of this utility model, there are two extensions 42, which are symmetrically arranged on opposite sides of one end of the column 41 with respect to the center of the column 41.

[0047] In this embodiment, the pin 4 has two extensions 42 at one end of its post 41, which are symmetrically distributed on both sides of the post 41. When the pin 4 is in the locked state, the two extensions 42 respectively form a locking contact with the inner wall of the fourth through hole 62 of the board end connector 20, so that the pin 4 is constrained in both the circumferential and axial directions. The symmetrically distributed extensions 42 can balance the forces on both sides and avoid skewing or jamming caused by forces on one side.

[0048] In an embodiment of this utility model, a first step 411 is provided on the outer periphery of the column 41, and the first step 411 extends along the circumferential direction of the column 41.

[0049] The inner wall of the second through hole 14 is provided with a first limiting part 141. When the pin 4 is in the unlocked state, the first step 411 abuts against one side of the first limiting part 141 to prevent the pin 4 from moving in the opposite direction.

[0050] In this embodiment, the first step 411 is an annular protrusion formed circumferentially on the outer periphery of the column 41. It can be achieved through machining or injection molding, and its width and height can be adjusted according to the dimensions of the column 41. The first limiting part 141 is a partially protruding blocking structure on the inner wall of the second through hole 14. It can be achieved through stamping or die forming, and its position corresponds to the movement trajectory of the first step 411. When the pin 4 is switched to the unlocked state, the column 41 moves axially along the second through hole 14 until the first step 411 contacts the first limiting part 141. At this time, the end face of the first step 411 forms a surface contact with the side face of the first limiting part 141. Since the first step 411 extends continuously circumferentially, when the pin 4 is subjected to an external force and moves in the opposite direction, the first limiting part 141 restricts the column 41 from disengaging from the second through hole 14 by blocking the axial displacement path of the first step 411.

[0051] like Figures 7 to 9As shown, in another embodiment, the first limiting part 141 is an independent component that passes through the clearance hole in the side wall of the base 11 into the second through hole 14 and abuts against the outer peripheral wall of the pin 4. When the pin 4 is switched to the unlocked state, the column 41 moves axially along the second through hole 14 until the first step 411 contacts the first limiting part 141. At this time, the end face of the first step 411 and the side face of the first limiting part 141 form a surface contact to prevent the pin 4 from being pulled out of the second through hole 14.

[0052] In an embodiment of this utility model, the pin 4 further includes a knob 43, which is located at the other end of the column 41 opposite to the extension 42. Driving the knob 43 can move or rotate the column 41 and the extension 42. The knob 43 is fixed to the end of the column 41 by a threaded connection or a snap-fit. When the knob 43 is subjected to an axial thrust, the column 41 moves axially along the second through hole 14, causing the extension 42 to enter or exit the locked position. When the knob 43 is subjected to a rotational torque, the column 41 rotates circumferentially along the second through hole 14, causing the extension 42 to form an angular limit with the fourth through hole 62 of the board end connector 20.

[0053] In this embodiment, the knob 43 is a manually operated component installed at the end of the column 41. Specifically, it can be implemented using injection-molded plastic or metal parts, and its surface can be provided with anti-slip textures to increase friction.

[0054] In an embodiment of this utility model, the wire connector 10 further includes an elastic element 5, which is sleeved on the outer periphery of the column 41. One end of the elastic element 5 abuts against the other side of the first limiting part 141, and the other end of the elastic element 5 abuts against a surface of the knob 43 facing the extension part 42.

[0055] In this embodiment, the elastic element 5 is a mechanical component capable of elastic deformation, specifically a helical spring or a wave spring. Its function is to provide a restoring force when the pin 4 is in the unlocked state, causing the pin 4 to automatically reset. When the knob 43 is pushed, the column 41 drives the extension 42 to move axially along the second through hole 14. At this time, the elastic element 5 is compressed by the knob 43 and the first limiting part 141. When the external force is removed, the elastic element 5 pushes the knob 43 to move in the opposite direction by restoring its deformation, so that the column 41 returns to its initial position.

[0056] In an embodiment of this utility model, the knob 43 is provided with two rotating arms 431, which are connected to opposite sides of the knob 43. The length of one rotating arm 431 is greater than the distance between the knob 43 and the outer shell 1 in the circumferential direction, so as to distinguish the rotation direction of the knob 43.

[0057] In this embodiment, when the knob 43 needs to be rotated, the operator determines the rotation direction by observing the relative positions of the two rotating arms 431 and the outer casing 1. The longer rotating arm 431 will contact the side wall of the outer casing 1 to form a physical block when rotating clockwise, and will remain free to move when rotating counterclockwise. This forms a directional differential tactile feedback, avoiding confusion about the rotation direction caused by misoperation.

[0058] In an embodiment of this utility model, the outer peripheral wall of the column 41 is provided with a second limiting part 412, and the inner wall of the second through hole 14 is provided with a second step 142. The second step 142 extends along the axial direction of the second through hole 14. When the pin 4 is in the unlocked state, the second limiting part 412 abuts against the second step 142 to prevent the pin 4 from rotating in the opposite direction.

[0059] In this embodiment, when the pin 4 is in the unlocked state, the column 41 moves axially to the position corresponding to the second limiting part 412 and the second step 142. At this time, if an attempt is made to rotate the pin 4 in the opposite direction, the second limiting part 412 will interfere with the second step 142, preventing the pin 4 from continuing to rotate.

[0060] Please see Figure 11 The present invention also proposes a board-end connector 20 including a housing 6, a plurality of second terminal modules 7 and two hooks 8. The housing 6 has a plurality of third through holes 61 and fourth through holes 62 spaced apart; each second terminal module 7 passes through a third through hole 61; each hook 8 is provided on one side surface of the housing 6.

[0061] In this embodiment, the housing 6 serves as a support structure for the terminal modules and the hook 8, and can be implemented using injection molding, for example, using high-temperature resistant plastic materials. Its function is to provide a fixed position for the terminal modules and form external protection. The third through hole 61 is a channel structure penetrating the housing 6, and can be designed with a rectangular or circular cross-section. It is used to form a plug-in fit with the protrusion 12 of the wire connector 10, realizing the electrical connection between the terminal modules. The fourth through hole 62 is a channel structure spaced apart from the third through hole 61, and can be a circular through hole. It is used to accommodate the movable insertion of the pin 4 of the wire connector 10, forming a fitting space for axial movement and circumferential rotation. The second terminal module 7 is a conductive contact component, and can be made of copper alloy stamping. Its end can be designed as an elastic contact piece to achieve a reliable connection with the terminal of the wire connector 10. The hook 8 is a protruding structure with a locking function, and can be designed with an integrated barb shape formed on the side wall of the housing 6, used to form a mechanical lock with the fastener 3 of the wire connector 10.

[0062] Please see Figure 12The present invention also proposes a connector assembly 100 including the wire end connector 10 and the board end connector 20 as described above. The protrusion 12 of the wire end connector 10 is inserted into the third through hole 61 of the board end connector 20. One end of the fastener 3 is fastened to the hook 8. The pin 4 is movably inserted into the fourth through hole 62 and switched to the locked state to fix the connection between the wire end connector 10 and the board end connector 20.

[0063] In this embodiment, when the board-end connector 20 mates with the wire-end connector 10, the protrusion 12 of the wire-end connector 10 inserts into the third through hole 61 to complete the electrical connection of the terminal module. Simultaneously, the hook 8 engages with the end of the fastener 3 of the wire-end connector 10. After the pin 4 of the wire-end connector 10 passes through the fourth through hole 62, it switches to a locked state through axial movement. At this time, the extension 42 of the pin 4 engages with the edge of the fourth through hole 62, preventing the pin 4 from retracting. This structure achieves initial fixation through the cooperation of the hook 8 and the fastener 3, and then forms a secondary lock through the locking state of the pin 4, thereby replacing the traditional screw fixing method.

[0064] 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.
