Description

Technical Field

[0001] This invention relates to the field of connector equipment technology, specifically to a high-density connector assembly device with intelligent overcurrent protection. Background Technology

[0002] A search revealed Chinese Patent Publication No. CN207250775U, which discloses a multi-pin high-density connector assembly, including a female contact and a male contact. This multi-pin high-density connector assembly, through the setting of an alignment device, can ensure the accuracy of the docking process between the pin and the socket. The second bent rod drives the roller on the support rod to roll on the inner wall of the fixed frame, thereby limiting the position of the male contact and ensuring that the pin can accurately dock with the socket. The above-mentioned prior art has the following defects: there is no stable structure, and there is a possibility of detachment after docking, which will lead to the inability to transmit current and signals normally. In addition, the shell and cable are not detachable. When the pins in the connector are damaged or the internal components of the connector are damaged, the user can only replace the whole thing, which increases the labor cost. After replacement, the old data cable is directly discarded, which cannot be repaired and recycled, resulting in waste of resources. Therefore, a high-density connector assembly device with intelligent overcurrent protection is proposed to solve the above-mentioned problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a high-density connector assembly device with intelligent overcurrent protection, which has the following advantages:

[0018] 1. This high-density connector assembly with intelligent overcurrent protection, through the setting of a connection mechanism and a fixing mechanism, the cable base and the movable seat cooperate with the mounting groove through the arc groove to fix the cable. The extrusion plate drives the rotating drum to swing, which drives the wedge-shaped block to move and release its fixation on the fixed seat, so that the connection between the movable seat and the cable base can be disassembled.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 This invention provides a technical solution: a high-density connector assembly device with intelligent overcurrent protection, including two outer plates 1, symmetrically distributed left and right, serving as the base of the entire device, providing structural support and mounting plane, ensuring symmetrical distribution of components on both sides, facilitating modular assembly. A male contact 2 extending to its left side is fixedly installed on the right side of the right outer plate 1, engaging with a female contact 3 on the left side to form a conductive path for transmitting current or signals. A female contact 3 extending to its right side is fixedly installed on the left side of the left outer plate 1. A groove 4 is formed on the inner side of the female contact 3. An on / off switch 5 is fixedly installed on the top of the male contact 2 to monitor the current passing through the contact in real time. The sensor signal is transmitted to a built-in microcontroller and compared with a preset safety threshold. If the current exceeds the limit, the MCU triggers a protection action with a response time of ≤10ms (short circuit protection) and ≤100ms (overload protection). It supports dry contact signal output and can be connected to an external alarm device or control system. Both outer plates 1 have housing assemblies 6 on opposite sides. The left housing assembly 6 is located outside the female contact 3, and the right housing assembly 6 is located outside the male contact 2. Both the male contact 2 and the female contact 3 have connecting mechanisms 7 located inside the housing assembly 6 on opposite sides. The front and rear sides of the connecting mechanism 7 are equipped with fixing mechanisms 8. The left side of the left outer plate 1 has a stabilizing mechanism 9, and the left side of the right outer plate 1 has a wedge-shaped clamping plate 10. For electrical protection, the on / off switch 5 monitors the current and quickly cuts off the circuit in case of abnormality to protect equipment and personnel safety.

[0031] The housing assembly 6 includes a bottom shell 61. The housing assembly 6 has a closed design to adapt to harsh environments (such as humidity and dust). The bottom shell 61 is fixedly installed on the opposite sides of the two outer plates 1. The left bottom shell 61 is located outside the female contact 3, and the right bottom shell 61 is located outside the male contact 2. The top shell 62, which fits against the outer plate 1, is movably installed on the top of the bottom shell 61 and is closed with the bottom shell 61 by a connecting bolt 64 to form a closed space, protecting the internal components from the influence of dust, humidity and other environmental factors. Connecting blocks 63 are fixedly installed on the front and rear sides of the bottom shell 61 and the top shell 62. Connecting bolts 64 are movably installed between the upper and lower connecting blocks 63 to ensure the stability of the housing structure and prevent loosening caused by vibration or impact. The symmetrical distribution simplifies the assembly process. The connecting bolts 64 adopt an anti-loosening design (such as spring washers) to prevent loosening after long-term use.

[0032] Both the bottom shell 61 and the top shell 62 have through holes on their side walls for cables to pass through. The bottom shell 61 and the top shell 62 are symmetrically distributed vertically.

[0033] The connecting mechanism 7 includes a cable base 71, with the left cable base 71 fixedly installed on the left side of the female contact 3 and the right cable base 71 fixedly installed on the right side of the male contact 2. A movable seat 72 is movably installed on the top of the cable base 71.

[0034] The top of the cable base 71 has an installation groove, and the bottom of the movable seat 72 has an arc-shaped groove that matches the installation groove. Anti-slip textures can be added to the arc-shaped groove to improve the stability of the cable. The cable can be clamped by the arc-shaped groove cooperating with the installation groove of the cable base 71 to accommodate different wire diameters.

[0035] The fixing mechanism 8 includes a fixing base 81. Fixing bases 81 are fixedly installed on both the front and rear sides of the cable base 71, providing a target for the wedge-shaped locking block 86. An outer frame 82 is fixedly installed on both the front and rear sides of the movable base 72. A support rod 83 is fixedly installed between the left and right sides of the inner wall of the outer frame 82, forming a rotating support for the rotating drum 84, allowing the rotating drum 84 to rotate when the pressing plate 87 is pressed down. The rotating drum 84 is rotatably connected to the outer side of the support rod 83. An extension extending to the fixing base is fixedly installed at the bottom of the rotating drum 84. On one side of the upright plate 85, a wedge-shaped locking block 86 is fixedly installed on one side of the upright plate 85, which engages with the fixing seat 81. The inclined design at the bottom facilitates insertion into the locking slot of the fixing seat 81, forming a self-locking structure. A pressing plate 87 extending to the top of the outer frame 82 is fixedly installed on the top of the rotating cylinder 84, providing an operating interface. The user can fix / unlock the device by pressing. A connecting spring 88 is fixedly installed on one side of the upright plate 85, which is fixedly connected to the inner wall of the outer frame 82. The entire mechanism realizes "one-handed pressing to fix and one-handed pressing to release", improving operating efficiency.

[0036] A slot is provided on one side of the fixed base 81. The size of the slot is adapted to the wedge-shaped block 86. The bottom of the wedge-shaped block 86 is designed to be inclined. The upper and lower sides of the inner wall of the outer frame 82 are designed to be open. A sponge pad is provided on one side of the extrusion plate 87 to increase friction and prevent slippage during operation.

[0037] The stabilizing mechanism 9 includes an outer box 91. Two outer boxes 91 are fixedly installed on the left side of the left outer plate 1, supporting a stabilizing frame 92 and a U-shaped plate 93, providing an insertion channel for the wedge-shaped plate 10. A stabilizing frame 92 is fixedly installed on the inner wall of the outer box 91 near the bottom shell 61. A U-shaped plate 93 extending to the inner side of the outer box 91 is slidably installed on the outer side of the outer box 91. A triangular block 94 is fixedly installed on the outer side of the U-shaped plate 93, with its right inclined surface matching the left inclined surface of the wedge-shaped plate 10 to form an inclined surface compression interlock. A U-shaped rod 95 extending to the outer side of the outer box 91 is fixedly installed on the inner side of the U-shaped plate 93, providing a manual unlocking operation point. A fixing spring 96 fixedly connected to the inner wall of the outer box 91 is fixedly installed on the inner side of the U-shaped plate 93, providing a reset function. After unlocking, the U-shaped plate 93 is automatically pushed back, ready for the next insertion.

[0038] The left side of the wedge-shaped card plate 10 is inclined, and the right side of the triangular block 94 is inclined. The inclination angle of the wedge-shaped card plate 10 and the triangular block 94 needs to be precisely calculated to ensure that the insertion force and the holding force are balanced. The right side of the inner wall of the outer box 91 has a through hole that matches the wedge-shaped card plate 10. The inner side of the left outer plate 1 has a rectangular hole that matches the wedge-shaped card plate 10. The inner side of one side of the outer box 91 has a limiting hole that matches the U-shaped plate 93 and the U-shaped rod 95. The limiting hole constrains the sliding trajectory of the U-shaped plate 93 to prevent it from shifting and getting stuck. The inner side of the stabilizing frame 92 has a limiting groove that matches the wedge-shaped card plate 10. The inner limiting groove constrains the position of the wedge-shaped card plate 10 to prevent it from shaking after insertion. When the wedge-shaped card plate 10 extends to the inner side of the outer box 91, it fits against one side of the triangular block 94.

[0039] In use, fix the positive contact 2 and the negative contact 3 to the left and right outer plates 1 respectively, ensuring that the slots 4 are aligned. Install the outer casing assembly 6, tighten the connecting bolt 64, place the cable into the mounting slot of the cable base 71, close the movable seat 72, and press down the squeezing plate 87 to make the wedge-shaped locking block 86 engage with the fixed seat 81 to complete the cable fixing. Push the right outer plate 1 to insert the wedge-shaped locking plate 10 into the through hole of the left outer box 91. The U-shaped plate 93 will automatically lock under the action of the fixing spring 96, completing the connection of the two components. Set the upper limit of the safe current (e.g., 1A-63A) using the button or knob, increasing the current each time. Reduce 1A, save settings automatically, set overload protection delay (1-600 seconds) to adapt to different load characteristics (such as motor starting impact), select automatic reset (power supply is automatically restored after fault clearing) or manual reset (reset by pressing the button), after connecting the power supply, the device monitors the current in real time, and the LED indicator shows the operating status (green for normal, red for overcurrent), check whether the load is short-circuited or overloaded, after troubleshooting, press the reset button (if it is manual reset) to restore power supply, check the tightness of the connection mechanism 7 every six months, clean the oxide layer on the surface of the contact parts to ensure conductivity.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] In summary, this high-density connector assembly with intelligent overcurrent protection, through the connection mechanism 7 and the fixing mechanism 8, secures the cable by having the cable base 71 and the movable seat 72 cooperate with the mounting groove through the arc groove. The pressing plate 87 drives the rotating drum 84 to swing, causing the wedge-shaped locking block 86 to move and release its fixation on the fixed seat 81, thus allowing the connection between the movable seat 72 and the cable base 71 to be disassembled. The connecting spring 88 provides a restoring force to ensure stable fixation, achieving the purpose of easy cable disassembly. Through the stabilizing mechanism 9 and the wedge-shaped locking plate 10, the wedge-shaped locking plate 10 of the right outer plate 1 is inserted into the through hole of the left outer box 91, pushing the U-shaped plate 93 to compress the fixing spring 96. When the wedge plate 10 reaches the designated position, the triangular block 94 fits into the wedge plate 10, forming a mechanical interlock. The limiting groove of the stabilizing frame 92 further constrains the position of the wedge plate 10 to prevent loosening, thus achieving the purpose of having a stable structure. This solves the problem that without a stable structure, there may be a situation where the connection is not properly completed and the connection may fall off, which would prevent the normal transmission of current and signals. In addition, the housing and cable are not detachable. If the pins in the connector are damaged or the internal components of the connector are damaged, the user can only replace the whole thing, which increases the labor cost. After replacement, the old data cable is directly discarded and cannot be repaired and recycled, resulting in a waste of resources.
