Description

Technical Field

[0001] This invention relates to the field of electrical connection device technology, specifically a waterproof connector for use in power distribution control equipment. Background Technology

[0002] Power distribution control equipment, such as distribution cabinets, control cabinets, and outdoor distribution boxes, is widely used in power transmission, industrial control, and outdoor power distribution scenarios. These devices often require connectors to achieve rapid electrical connections between internal circuits and external cables. Waterproof connectors, as key connection components, must possess excellent waterproof and dustproof capabilities to adapt to harsh working conditions such as humidity and dust, ensuring the safety of electrical connections.

[0003] In existing technologies, waterproof connectors for power distribution control equipment mostly adopt a male-female plug-in structure, and their waterproofing relies mainly on the static adhesion of a single sealing ring to the mating surfaces. However, existing connectors have significant drawbacks in practical applications: First, a single sealing ring can only form a single-layer seal, which is not reliable enough. Rainwater or moisture can easily seep in through the joint gaps, especially after equipment vibration or long-term use, the sealing ring is prone to aging and deformation, further reducing the waterproofing effect; Second, existing connectors do not have a dedicated anti-loosening locking structure. When the equipment vibrates or the ambient temperature changes causing thermal expansion and contraction, relative slippage or even loosening can easily occur between the male and female connectors, resulting in a loose connection and poor contact.

[0004] Therefore, a solution is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waterproof connector for power distribution control equipment, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waterproof connector for power distribution control equipment, comprising a power distribution control box, wherein a connector assembly is fixedly mounted on the outer side of the power distribution control box, the connector assembly comprising a female socket detachably mounted on the outer wall of the power distribution control box, and a male socket axially inserted into the female socket, wherein an annular mating groove is formed on the outer peripheral side wall of the male socket, and a plurality of guide grooves are formed on the circumferential end face of the female socket, and a plurality of movable plates are slidably connected to the internal cavity of the female socket, wherein the inner side of the movable plates is provided with The device has a mating groove, and a sealing pressure plate for radial sealing is connected to the outer side of the mating groove via a connecting rod. A guide rod corresponding to the number of insertion grooves is fixedly connected to the outer wall of the male connector's insertion end. The outer surface of the guide rod has a wire bevel. When the male connector and the female connector are axially aligned, the guide rod is inserted directionally along the insertion groove. The wire bevel on the outer side of the guide rod abuts against and pushes the inner side wall of the mating groove, causing the movable plate to move radially. The movable plate, through the connecting rod, drives the sealing pressure plate to move radially synchronously, forming a radial compression seal.

[0007] Through the above technical solution, the annular mating groove on the outer periphery of the male seat cooperates with the radially linked sealing pressure plate inside the female seat. By utilizing the inclined surface of the guide rod and the inclined surface of the movable plate's mating groove, the axial insertion action of the male seat is transformed into the radial extrusion motion of the sealing pressure plate. This allows the sealing pressure plate to tightly fit into the mating groove to form a continuous sealing strip, effectively preventing rainwater from seeping in from the mating gap. This significantly improves the sealing reliability and waterproof performance of the connector under harsh conditions such as humidity and outdoor environments.

[0008] Preferably, the upper end face of the male seat has two mounting grooves along its length. Two electromagnetic adsorption blocks are fixedly installed in the mounting grooves. One of the electromagnetic adsorption blocks has a waterproof cover fixedly connected to its outer end face. When the guide rod is fully inserted and electrically connected, the electromagnetic adsorption block in the mounting groove is energized and generates a magnetic attraction force, which drives the waterproof cover to slide out axially until the waterproof cover completely covers the mating part of the female seat and the male seat, forming a peripherally closed two-stage waterproof sealing structure.

[0009] The above technical solution can add external full-enclosure protection on the basis of radial sealing, further blocking rainwater intrusion from the outside of the joint gap, achieving double waterproof protection and greatly improving the sealing stability in harsh environments.

[0010] Preferably, two fixed shells are symmetrically fixedly connected in the internal cavity of the female seat. A locking baffle is elastically connected in the internal cavity of the fixed shell through a connecting spring. A rigid insert is fixedly provided on the outer end face of the locking baffle. The outer walls of the two guide rods are provided with insertion holes that are adapted to the inserts. When the guide rods are fully inserted into the insertion slots and in place, the inserts automatically engage with the insertion holes under the elastic restoring force of the connecting spring, thereby achieving axial anti-disengagement locking and fixation between the female seat and the male seat.

[0011] The above technical solution automatically locks the axial connection after insertion, effectively resisting the risk of loosening caused by equipment vibration and thermal expansion and contraction, and ensuring long-term stable and reliable electrical connection.

[0012] Preferably, the upper end face of the female seat is slidably provided with an unlocking push rod in the vertical direction, the bottom end of the unlocking push rod is fixedly connected to an insertion block, the bottom end of the insertion block is provided with a second inclined surface, two linkage frames are arranged laterally on the inner side of the female seat, an unlocking slide rod is installed on one side of the linkage frame, and the inner end face of the unlocking slide rod is provided with a first inclined surface that matches the second inclined surface.

[0013] The above technical solution enables the locking structure to be quickly released through a simple pressing action. The inclined plane is used to convert the vertical force into a horizontal thrust, making the unlocking operation easier and improving the efficiency of disassembly and maintenance.

[0014] Preferably, the linkage frame is elastically connected to the internal cavity of the female seat by a return spring, and the outer periphery of the unlocking push rod is fitted with a return spring.

[0015] The above technical solution can automatically reset the linkage frame and the unlocking push rod after the unlocking action is completed.

[0016] Preferably, one end of the connecting spring is fixedly connected to the inner wall of the fixed shell, and the other end of the connecting spring is fixedly connected to the outer end face of the locking baffle.

[0017] The above technical solution ensures that the connecting spring is securely installed, provides a continuous elastic restoring force to the locking baffle, and prevents the spring from shifting after long-term use.

[0018] Preferably, there are eight inclined wires, which are symmetrically arranged in two rows along the outer side of the plug-in end face of the female connector. The two inclined wires on the upper side correspond to the upper sealing plate, the two inclined wires on the lower side correspond to the lower sealing plate, and the two inclined wires in the middle correspond to the sealing plate on the side.

[0019] The above technical solution can make the thrust of the guide rod on the sealing pressure plate in all directions uniform, avoid excessive force on one side leading to sealing deviation or wear, and ensure the consistency and stability of circumferential sealing.

[0020] Preferably, the installation position of the movable plate corresponds one-to-one with the position of the inclined surface of the wire, and the sealing pressure plate is made of elastic wear-resistant sealing material, forming an interference fit with the inner wall of the docking groove.

[0021] The above technical solution ensures that each wire bevel accurately drives the corresponding movable plate and sealing plate, and the sealing plate achieves tight fit through the interference fit of elastic material.

[0022] Preferably, the outer peripheral sidewall of the male seat is provided with a mating groove, and when the sealing pressure plate is embedded in the mating groove, a continuous annular sealing band can be formed along the circumference.

[0023] The above technical solution enables the sealing plate to form an uninterrupted sealing line in the mating groove, eliminating the defect of thin local seals and improving the integrity of the overall waterproof seal.

[0024] This invention provides a waterproof connector for power distribution control equipment. It has the following advantages:

[0025] 1. This invention features an annular mating groove on the outer periphery of the male connector, which, in conjunction with a radially movable sealing plate on the inner side of the female connector, creates a radial compression seal when the male and female connectors are inserted. This provides the first layer of waterproof protection. Simultaneously, a waterproof cover on the male connector, after insertion, covers the mating area between the male and female connectors, forming a secondary, closed-loop waterproof seal. This dual sealing effectively prevents rainwater and moisture from seeping into the interior through the joint, significantly improving the waterproof performance of the connector under harsh conditions such as dampness and outdoor environments.

[0026] 2. The present invention provides a locking baffle and a plug block with elastic connection inside the female seat. After the male seat is inserted into place, the plug block can automatically lock into the insertion hole of the guide rod under the action of the connecting spring, so as to realize the axial anti-disengagement locking of the male and female seats, effectively avoid the problem of loose connection caused by equipment vibration or external force pulling, and ensure the stability of electrical connection.

[0042] The technical solutions in 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.

[0043] Please see the appendix Figure 1 -Appendix Figure 9This invention provides a waterproof connector for power distribution control equipment, primarily used in electrical connection scenarios for power distribution control equipment such as distribution cabinets and control cabinets. The overall structure uses a power distribution control box 1 as the mounting base. A female connector 2 is detachably fixed to the outer wall of the power distribution control box 1. The female connector 2 serves as the fixed end structure of the connector. A positioning stop is provided on the outer contour of the female connector 2, allowing for precise alignment with the positioning holes of the power distribution control box 1 during installation. The insertion end face of the female connector 2 has several circumferentially circumferentially formed insertion grooves 57 for guiding and mating. These grooves 57 guide the guide rod 54 of the male connector 3, reducing alignment difficulty and insertion resistance during insertion. Simultaneously, the grooves circumferentially limit the guide rod 54, effectively preventing circumferential torsion of the male connector 3 relative to the female connector 2 during insertion, ensuring consistent insertion positions and guaranteeing the stability of electrical contact.

[0044] Multiple movable plates 52 are slidably connected to the internal cavity of the female seat 2. The number of movable plates 52 corresponds one-to-one with the insertion slots 57, and they are arranged in the four directions of the cavity: top, bottom, left, and right. The movable plates 52 are made of rigid insulating material, which can stably withstand the lateral thrust of the guide rod 54. The inner side of the movable plate 52 is provided with a mating groove 56, which is an arc-shaped inner groove. This arc-shaped groove structure can form an inclined surface mating with the wire inclined surface 55 on the guide rod 54. When the male seat 3 is axially inserted, the axial force is converted into a radial thrust, which drives the movable plate 52 to move smoothly in the radial direction.

[0045] A sealing pressure plate 51 is connected to the outer side of the movable plate 52 via a connecting rod 53. The connecting rod 53 is made of rigid insulating plastic rod, and its two ends are fixed to the movable plate 52 and the sealing pressure plate 51 by injection molding. It can stably transmit the radial displacement of the movable plate 52, ensure that the sealing pressure plate 51 moves synchronously with the movable plate 52, and ensure the sealing fit accuracy.

[0046] The male connector 3 and the female connector 2 are axially mated together, forming a movable end structure for the connector. The entire structure is made of the same insulating and flame-retardant engineering plastic as the female connector 2. One end connects to an external cable, and the other end is a plug-in end. The outer peripheral side wall of the male connector 3 has an annular mating groove 8. The depth of the mating groove 8 is precisely matched with the size of the sealing pressure plate 51, and the groove wall is smooth and flat, providing a pressing mating surface for the sealing pressure plate 51.

[0047] The outer wall of the male connector 3 is fixedly connected with guide rods 54, each corresponding to a specific number of insertion slots 57. The guide rods 54 are made of rigid insulating plastic, are cylindrical, and their length precisely matches the depth of the insertion slots 57, ensuring that the guide rods 54 can fully extend into the insertion slots 57 during insertion. The outer surface of the guide rods 54 has wire bevels 55. Eight wire bevels 55 are provided, arranged symmetrically in two rows along the outer side of the female connector 2's insertion end face. The two upper wire bevels 55 correspond to the upper sealing plate 51, the two lower wire bevels 55 correspond to the lower sealing plate 51, and the two middle wire bevels 55 correspond to the side sealing plate 51.

[0048] Two mounting grooves 42 are formed along the length of the upper end face of the male seat 3. The mounting grooves 42 are rectangular grooves used to fix the electromagnetic adsorption blocks 43. Two electromagnetic adsorption blocks 43 are fixedly installed in the mounting grooves 42. The electromagnetic adsorption blocks 43 are small DC electromagnets and are electrically connected to the power supply circuit inside the power distribution control box 1. When energized, they can generate a magnetic attraction force. A waterproof cover 41 is fixedly connected to the outer end face of one of the electromagnetic adsorption blocks 43. The waterproof cover 41 is made of elastic wear-resistant and waterproof rubber material. Its inner diameter is slightly larger than the outer diameter of the female seat 2. Under normal conditions, it shrinks and fits against the surface of the male seat 3 without affecting the insertion operation. When the male seat 3 is inserted into place and electrical conduction is achieved, the electromagnetic adsorption block 43 is energized and generates a magnetic attraction force, which drives the waterproof cover 41 to slide smoothly along the axis until it completely covers the docking part of the female seat 2 and the male seat 3, forming an outer closed secondary waterproof sealing structure to prevent rainwater and moisture from seeping into the docking gap from the outside.

[0049] The sealing plate 51 is made of elastic wear-resistant sealing material, which can maintain sealing performance in humid environments for a long time. When the movable plate 52 drives the sealing plate 51 to move radially, the sealing plate 51 can be embedded in the mating groove 8 and form an interference fit with the inner wall of the mating groove 8, forming a continuous and complete annular sealing band in the circumferential direction. This sealing structure can form the first waterproof barrier from the inside of the mating gap, effectively preventing rainwater from seeping into the connector and significantly improving the waterproof performance under harsh working conditions.

[0050] Two fixed shells 74 are symmetrically fixedly connected in the internal cavity of the female seat 2. The fixed shells 74 are made of rigid metal material and are stamped and formed. They are firmly fixed to the inner wall of the cavity of the female seat 2 by fasteners, forming a closed cavity inside to accommodate the locking baffle 79 and the connecting spring 710. This can protect the internal elastic components from dust and limit the movement of the locking baffle 79.

[0051] A locking baffle 79 is elastically connected to the internal cavity of the fixed shell 74 via a connecting spring 710. One end of the connecting spring 710 is fixedly connected to the inner wall of the fixed shell 74, and the other end is fixedly connected to the outer end face of the locking baffle 79. After assembly, it is in a pre-compressed state and provides elastic restoring force to the locking baffle 79 under normal conditions.

[0052] The locking baffle 79 is a rigid insulating plate that can slide smoothly in the horizontal direction within the cavity of the fixed shell 74. A rigid plug 76 is fixedly installed on the outer end face. The outer walls of the two guide rods 54 are provided with plug holes 6 that are adapted to the plug 76. The shape of the plug holes 6 matches the plug 76. When the guide rods 54 are fully inserted into the insertion slots 57 and in place, the plug 76 can be quickly locked into the plug holes 6 under the elastic restoring force of the connecting spring 710, realizing the anti-disengagement locking and fixing between the female seat 2 and the male seat 3. This effectively resists the risk of loosening caused by equipment operation vibration and thermal expansion and contraction, and ensures the stability of the electrical connection.

[0053] The upper surface of the female seat 2 is slidably provided with an unlocking push rod 71 in the vertical direction. The unlocking push rod 71 is a cylindrical metal rod with an anti-slip pressing head at the top for easy manual application of pressing force. A return spring is sleeved on the outer periphery of the unlocking push rod 71. The upper end of the return spring abuts against the bottom of the pressing head of the unlocking push rod 71, and the lower end abuts against the upper surface of the female seat 2. Under normal conditions, the unlocking push rod 71 is kept in the initial raised position and can automatically reset after pressing.

[0054] An insertion block 72 is fixedly connected to the bottom end of the unlocking push rod 71. The bottom end of the insertion block 72 has a second inclined surface 78 with a regular inclination angle and a smooth, wear-resistant surface. Two linkage frames 75 are arranged laterally on the inner side of the female seat 2. The linkage frames 75 are made of rigid insulating material and are elastically connected to the internal cavity of the female seat 2 by a return spring. They can slide back and forth in the horizontal direction. The return spring provides the return force for the linkage frame 75, ensuring that the linkage frame 75 can automatically return to its original position after unlocking.

[0055] An unlocking slide bar 73 is installed on one side of the linkage frame 75. The inner end face of the unlocking slide bar 73 has a first inclined surface 77 that is adapted to the second inclined surface 78. Its surface is smooth and fits snugly. When it is necessary to separate the female seat 2 and the male seat 3, press down the unlocking push bar 71 to drive the insertion block 72 to move down synchronously. The second inclined surface 78 and the first inclined surface 77 slide together, converting the vertical pressing force into a horizontal pushing force, which pushes the unlocking slide bar 73 and the linkage frame 75 to move horizontally. The linkage frame 75 further drives the locking baffle 79 and the insertion block 76 to retract, so that the insertion block 76 disengages from the insertion hole 6, releasing the locking state between the female seat 2 and the male seat 3. The male seat 3 can then be easily pulled out. The operation is convenient and effortless.

[0056] Working principle: When using this device, its operating principle includes the following:

[0057] During the insertion operation, first align the male connector 3 with the insertion end face of the female connector 2, so that the multiple guide rods 54 on the outer wall of the male connector 3 correspond one-to-one with the insertion slots 57 opened on the end face of the female connector 2. At this time, as the male connector 3 continues to advance into the female connector 2, the inclined surface 55 of the guide rods 54 gradually contacts and presses the inner wall of the mating groove 56 on the inner side of the movable plate 52 inside the female connector 2. Under the guiding thrust of the inclined surface, the movable plate 52 moves radially along the inner cavity of the female connector 2. During the movement of the movable plate 52, the connecting rod 53 drives the sealing pressure plate 51 to move radially in sync, so that the sealing pressure plate 51 is embedded into the annular mating groove 8 on the outer peripheral side wall of the male connector 3. After being embedded, it forms a compression with the inner wall of the mating groove 8. In conjunction with the guide rod 54, the male and female seats 3 are fully inserted into the insertion slot 57, and the internal electrical contacts are connected. Then, the electromagnetic adsorption block 43 in the mounting slot 42 on the upper end of the male seat 3 is simultaneously energized. The electromagnetic adsorption block 43 generates a stable magnetic attraction force, which drives the waterproof cover 41 fixedly connected to it to slide smoothly outward along the axial direction. After the waterproof cover 41 extends outward, it completely covers the entire docking area of ​​the female seat 2 and the male seat 3, forming an outer closed waterproof sealing structure. This further blocks the intrusion of water vapor from the environment. Together with the first radial seal, it forms a double waterproof protection system, which greatly improves the water release effect.

[0058] As the male seat 3 is inserted into place, the locking baffle 79, driven by the elastic restoring force of the connecting spring 710, moves towards the guide rod 54. This causes the rigid insert 76, fixed to the outer end face of the locking baffle 79, to automatically engage with the insertion hole 6. After the insert 76 and the insertion hole 6 are precisely engaged, the axial relative displacement between the male seat 3 and the female seat 2 can be effectively restricted, thus preventing the male seat 3 and the female seat 2 from detaching and locking. When it is necessary to separate the male seat 3 and the female seat 2, simply press down on the unlocking push rod 71, which is vertically slidable on the upper end face of the female seat 2. When the unlocking push rod 71 is pushed down, it causes the insertion block 72, fixed at its bottom end, to move down synchronously. During the downward movement, the second inclined surface 78 at the bottom end of the insertion block 72 gradually squeezes... The first inclined plane 77, through the transmission of force between the inclined planes, pushes the unlocking slide rod 73 to move. When the unlocking slide rod 73 moves, it drives the linkage frame 75 to move laterally in sync. The linkage frame 75 further pushes the locking baffle 79 to move in the opposite direction against the elastic force of the connecting spring 710, so that the insert block 76 on the outside of the locking baffle 79 smoothly disengages from the insertion hole 6 on the side wall of the guide insert rod 54, thereby releasing the locking and fixing state between the male seat 3 and the female seat 2. At this time, the male seat 3 can be directly and smoothly pulled out from the female seat 2 along the axial direction to quickly complete the separation operation. After releasing the pressure on the unlocking push rod 71, the unlocking push rod 71 and the linkage frame 75 automatically spring back to reset under the elastic force of their respective matching reset springs, driving the locking baffle 79 to reset synchronously.
