Description

Technical Field

[0001] The present invention relates to the technical field of terminal wire connectors, in particular to an adaptive terminal wire connection system. Background Art

[0002] Existing multi-core plug / socket connection systems typically use a single-layer metal pin-socket combination or a single spring-type side-pressure contact structure, maintaining conduction through local contact pressure generated by elastic parts. When users need to manually power off, they often have to pull out the male and female connectors as a whole, which is very laborious. Traditional structures generally lack a self-reset mechanism that is linked to temperature rise and overcurrent faults. Once a single circuit short-circuits and generates heat, the heat will spread along the same core to the adjacent core, causing carbonization of the insulation layer, adhesion of the wire harness, and even overall fire. At the same time, insufficient contact caused by differences in pin length, shaking, or assembly tolerances often leads to a sudden increase in contact resistance and further heating. In high-density signal / power hybrid scenarios, if only one line has a short-circuit fault, traditional solutions cannot achieve single-circuit tripping and isolation, and the entire cable bundle is forced to be shut down for maintenance, seriously affecting system availability.

[0008] Preferably, two parallel rotating screws are rotatably inserted and engaged on the placement cavity, and the terminal thread transmission sleeve of the rotating screw is provided with a nut block, and the nut block is movably connected to the reinforcement frame through an adjusting connecting rod, wherein the nut block is prevented from rotating on the rotating screw by the adjusting connecting rod and the reinforcement frame; or the nut block is slidably engaged with the side of the conductive cable organizing cover facing the inner side of the placement cavity.

[0009] Preferably, a rotating screw mounting hole is provided at one end of the plug housing where the rotating screw is connected, and a mounting boss is fixed to one side of the rotating screw located inside the rotating screw mounting hole, and the mounting boss rotates in cooperation with the rotating screw mounting hole, and a threaded sleeve is also threadedly inserted into the inner wall of the rotating screw mounting hole, and the threaded sleeve is used to embed the mounting boss inside the rotating screw mounting hole to prevent the rotating screw from separating from the plug housing.

[0012] Compared with the prior art, the present invention has the following advantages: (1) The present invention evenly arranges multiple contact springs axially in the conductive copper tube, and the male plug can form a parallel contact channel with several springs when inserted at any depth. Compared with the traditional single-point or single-side spring structure, the multi-point contact not only disperses the current density of the unit spring and reduces the contact resistance, but also can keep the remaining springs in steady state conduction when individual springs are worn, oxidized or slightly mechanically deformed, significantly improving the reliability and vibration resistance after long-term plugging and unplugging, and avoiding the hidden danger of power failure or heating of the entire circuit due to single-point failure; (2) The hydraulic medium is encapsulated in the movable contact cavity of the present invention, and the chain action of temperature rise-volume expansion-piston push rod-elastic insulating rubber pad-moving and fixed contact decoupling realizes an immediate response to single-circuit overcurrent heating. When the current or ambient temperature does not exceed the set threshold, the rubber pad deforms to absorb the small pressure and remain closed; once the dangerous temperature rise is reached, the hydraulic push rod overcomes the spring resistance and pushes the movable contact to slide as a whole, causing the faulty line to lose power instantly, while other lines in the same row continue to work. This configuration has both overcurrent protection and self-limiting reset functions, which is equivalent to having a reusable thermal circuit breaker built into the plug, fundamentally eliminating wire harness burns and equipment chain burns caused by short circuits; (3) The present invention sets a double parallel rotating screw and a reinforcement frame, an insulating movable plate connecting rod mechanism in the placement cavity. The user only needs to use a wrench to rotate the hexagonal groove on the outer end to synchronously drive all the moving contact cavities away from the fixed contacts, realizing easy and fast maintenance of powering off the entire row. Compared with the traditional method of removing each core or plugging in the entire head, construction personnel can safely and accurately replace the wiring harness and perform routine inspections in a small cabinet or next to high-speed equipment, significantly reducing maintenance time and the risk of misoperation.

[0027] The elastic insulating rubber pad 121 contacts and mates with the fixed contact 117, is fixedly fitted with the piston push rod 120, and is coaxially fitted with the pressure-driven push tube 119. The outer diameter of the elastic insulating rubber pad 121 is smaller than the inner diameter of the pressure-driven push tube 119. A sealing plate 123 is fixedly and sealedly mounted on the end of the moving contact cavity 118 away from the fixed contact 117. Multiple thermal conductive plates 124 are fixedly mounted on the surface of the sealing plate 123 located inside the moving contact cavity 118. A contact extrusion block slide 125 is fixedly mounted on the surface of the sealing plate 123 located outside the moving contact cavity 118. A contact extrusion block 126 is slidably mounted on the contact extrusion block slide 125. A tension spring 128 is fixedly mounted between the opposing surfaces of the contact extrusion block 126 and the sealing plate 123. The ends of the tension spring 128 are fixedly fitted with the sealing plate 123 and the contact extrusion block 126. A plurality of conductive contact blocks 127 are arranged in a circular, equidistant array around the outer circumference of the contact extrusion block slide 125. These blocks 127 slide radially along the sealing plate 123. A conductive barrel 130 is provided on the outer sliding conductive sleeve of each of these blocks 127, and each barrel is provided with a vent 129. The movable contact cavity 118 is slidably mounted on the insulating movable plate 107. A spring 122 surrounds the movable contact cavity 118. Both ends of the spring 122 are fixedly connected to the end of the movable contact cavity 118 facing away from the insulating movable plate 107 and to the insulating movable plate 107 itself, thereby pushing the movable contact cavity 118 into contact with the fixed contact 117.

[0028] Two parallel rotating screws 109 are also rotatably inserted and engaged on the placement cavity 131. The terminal thread transmission sleeve of the rotating screw 109 is provided with a nut block 111. The nut block 111 is movably connected to the reinforcement frame 108 through an adjusting connecting rod 110, wherein the nut block 111 is prevented from rotating on the rotating screw 109 by the adjusting connecting rod 110 and the reinforcement frame 108; or the nut block 111 is slidably engaged with the side of the conductive cable organizing cover 102 facing the inner side of the placement cavity 131. A rotating screw mounting hole 112 is provided at one end of the plug housing 101 where the rotating screw 109 is connected. A mounting boss 113 is fixed to one side of the rotating screw 109 located inside the rotating screw mounting hole 112. The mounting boss 113 rotates with the rotating screw mounting hole 112. A threaded sleeve 114 is also threadedly inserted into the inner wall of the rotating screw mounting hole 112. The threaded sleeve 114 is used to embed the mounting boss 113 into the rotating screw mounting hole 112 to prevent the rotating screw 109 from separating from the plug housing 101. The conductive cable management cover 102 is fixedly mounted on the end of the plug housing 101 facing the receiving cavity 131, sealing the receiving cavity 131. The conductive cable management cover 102 is used to secure the conductive cables 103, arranging them in a parallel row. One end of the conductive cable 103 can pass through the conductive cable management cover 102 into the receiving cavity 131, securing the conductive barrel 130 and the conductive cable 103 in a conductive and fixed engagement. The conductive barrel 130 is fixedly engaged with the insulating movable plate 107. A protrusion with an enlarged diameter is provided on the end of the movable contact cavity 118 facing away from the fixed contact 117 to prevent the movable contact cavity 118 from separating from the insulating movable plate 107 under the action of the spring 122.

[0029] The working principle of an adaptive terminal wire connection system disclosed in the present invention is as follows: according to the user's usage requirements, an appropriate number of jack holes 104 are set (for example, ten in a row, two rows in total). When in use, it is only necessary to insert the male pin into the jack hole 104 (the conductive copper tube 105 inside the jack hole 104, the male pin will be in conductive extrusion contact with the contact spring 115 inside the conductive copper tube 105, and no matter how long the male pin is (it cannot exceed the axial length of the conductive copper tube 105), it can contact the corresponding number of contact springs 115, because multiple contact springs 115 are provided, ensuring the contact conductivity between the contact spring 115 and the male pin; if the length of the male pin can be enough to contact the fixed conductive block 116, a thread is provided at the end of the male pin, so that the thread cooperates with the thread of the fixed conductive block 116 to prevent the male pin from being accidentally pulled out of the conductive copper tube 105, thereby ensuring the stability of the electrical connection). At this time, the conductive connection between the corresponding male pin and the conductive cable 103 can be completed. When a short circuit or excessive load occurs during use, the heat in the series circuit will increase, which may seriously cause the insulation layer of the cable to melt and break. Therefore, when the heat in the circuit increases, the volume inside the moving contact cavity 118 will increase (hydraulic oil is provided inside the moving contact cavity 118. As the temperature rises, the pressure inside the moving contact cavity 118 increases and the volume increases). At this time, the pressure inside the moving contact cavity 118 will increase, thereby pushing the piston push rod 120 inside the pressure-driven push tube 119 to slide, and then pushing the fixed contact through the elastic insulating rubber pad 121. Point 117, since the fixed contact 117 is fixed to the fixed conductive block 116, and the fixed conductive block 116 is fixed to the plug housing 101 (the fixed conductive block 116, the conductive copper tube 105, and the jack hole 104 are fixedly connected), the fixed contact 117 cannot be pushed by the piston push rod 120, so the reaction force will push the movable contact cavity 118 away from the fixed contact 117, so that the movable contact cavity 118 is separated from the fixed contact 117, thereby cutting off the corresponding circuit (for example, ten in a row, two rows in total, that is, there are twenty circuits), and at the same time will not affect the operation of other circuits. The elastic insulating rubber pad 121 provided therein not only serves to insulate the contact between the piston push rod 120 and the fixed contact 117, but also, during the process of increasing pressure inside the moving contact cavity 118 (the process of increasing temperature and current), the elastic insulating rubber pad 121 will be squeezed and deformed. However, the deformation of the elastic insulating rubber pad 121 is maximum. At this time, the moving contact cavity 118 and the fixed contact 117 will not separate. They will only separate when the pressure inside the moving contact cavity 118 increases to a certain threshold (that is, they will only separate when the current reaches the set threshold).

[0030] The separation of the moving contact cavity 118 and the fixed contact 117 will cause the moving contact cavity 118 to slide on the insulating movable plate 107, and the moving contact cavity 118 will also slide in the conductive barrel 130 (the conductive barrel 130, the conductive contact block 127, the sealing plate 123, the contact extrusion block slide 125, the contact extrusion block 126, and the tension spring 128 are all conductively coordinated). Therefore, it is necessary to ensure the conductivity between the moving contact cavity 118 and the conductive barrel 130, and set the conductive contact block 127 to be in conductive sliding contact with the inner wall of the conductive barrel 130. The tension spring 128 pulls the contact extrusion block 126 to slide on the contact extrusion block slide 125, so that the contact extrusion block 126 squeezes all the conductive contact blocks 127 (the conductive contact block 127 is provided with an inclined surface on the side facing the contact extrusion block 126. The inclined surface causes the conductive contact block 127 to be squeezed toward the inner wall of the conductive barrel 130, thereby ensuring the contact force between the conductive contact block 127 and the conductive barrel 130).

[0031] The matching relationship among the rotating screw mounting hole 112, the mounting boss 113 and the threaded sleeve 114 is for facilitating the assembly of the rotating screw 109, wherein the rotating screw 109 is inserted into the interior of the placement cavity 131 through the rotating screw mounting hole 112, and then the threaded sleeve 114 is screwed into the rotating screw mounting hole 112. At this time, the rotating screw 109 cannot be separated from the rotating screw mounting hole 112, and the mounting boss 113 is integrated with the rotating screw 109, and the end of the rotating screw 109 away from the mounting boss 113 is rotationally matched with the inner wall of the placement cavity 131 (that is, the inner wall of the placement cavity 131 and the end of the rotating screw 109 away from the mounting boss 113 are provided with a circular groove for inserting the rotating screw 109). The user uses a wrench to rotate the rotating screw 109 (a hexagonal groove is provided at one end of the threaded sleeve 114). The rotation of the rotating screw 109 drives the nut block 111 to move along its own axis. Then, by adjusting the connecting rod 110, the reinforcing frame 108 is pulled to slide on the inner wall of the placement cavity 131. This then drives the insulating movable plate 107 to move synchronously, and the conductive barrel 130 to follow the movement, so that the movable contact cavity 118 on the insulating movable plate 107 is separated from the fixed contact 117 (because the fixed contact 117 on the fixed conductive block 116 cannot move). This is used to manually disconnect all circuits. In actual operation, it is inconvenient to insert and remove the plug housing 101.
