Description

Technical Field

[0001] The present invention belongs to the technical field related to electrical connectors, and more specifically, particularly relates to a micro rectangular electrical connector based on integrated components. Background Art

[0002] An electrical connector is a device commonly used in the fields of electronics, communications, automatic control, etc. It mainly plays the role of electrical connection and signal transmission. Due to different usage occasions, its shapes and specifications are also classified in many ways. In terms of appearance, there are rectangular and circular ones. Among them, the micro-rectangular electrical connector is a type of electrical connector classified by appearance. However, the electrical connectors in the prior art have the following defects:

[0003] 1. In the prior art, the connection process of the micro rectangular electrical connector is mostly improved by setting a damping member to improve the connectivity of the micro rectangular electrical connector. Some micro rectangular electrical connectors that adopt a locking structure have a complex structure and are not convenient to operate, and cannot effectively and quickly complete the locking to improve connectivity.

[0004] 2. In the prior art, the ports of the micro-rectangular electrical connector are either fixedly connected by screws or connected by movable snaps, so that the female and male ports of the micro-rectangular electrical connector are fixed. However, whether screws or movable snaps are used, there is a risk of detachment. For example, if the screw is screwed in too short, there is a problem of unstable connection, and the screw needs to be tightened. If an movable snap is used for connection, there is also a risk of falling off due to the small contact area of ​​the movable snap.

[0005] 3. In the prior art, the micro rectangular electrical connector is connected by screws, but the screws of the current electrical connector are relatively small.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a micro-rectangular electrical connector based on integrated components. Through the setting of elastic protrusions and annular protrusions, the movement of the head shell drives the second fixed plate and two positioning rods to move. The movement of the two positioning rods respectively pushes the movement of the two guide rods. The movement of the two guide rods drives the two circular plates to move in the two frames respectively. Through the outer side of the elastic protrusion and the outer side of the annular protrusion, the circular plate is moved smoothly in the frame, so that one end of the positioning rod can move horizontally smoothly in the frame, which is conducive to the smooth movement of one end of the pin in the connecting hole. Then, the distance between the two sides of the two limit plates that are close to each other gradually decreases from the side close to the first fixed plate to the side away from the first fixed plate, so that the friction force of the annular protrusion contacting the elastic protrusion gradually increases, further making the circular plate move smoothly in the frame, so that one end of the positioning rod can move horizontally smoothly in the frame, and the stability of the installation of the plug and the socket is improved. Finally, through the arrangement of the first hollow elastic member, the cylinder, the first piston plate, and the push rod, the circular plate continues to move to push the push rod and the first piston plate to move, and the first piston plate moves to allow the solution in the cylinder to enter the two first hollow elastic members through the two connecting tubes. The two first hollow elastic members expand and push the two movable plates to approach each other, and the two movable plates approach each other to drive the two limit plates to approach each other, and the two limit plates approach each other to drive several pairs of elastic protrusions to approach each other, thereby further increasing the friction force between the annular protrusion and the elastic protrusion, which is conducive to making one end of the pin slide smoothly in the connecting hole and improving the stability of the installation of the plug and the socket.

[0021] The present invention discloses a micro-rectangular electrical connector based on integrated components. Through the arrangement of a second hollow elastic part, a limiting plate, an elastic protrusion and a first through hole, movement of an operating rod drives movement of a second piston plate. Movement of the second piston plate further allows solution in the cylinder to enter the first hollow elastic part through a connecting tube. Solution in the first hollow elastic part enters the second hollow elastic part through a first solenoid valve. Expansion of the second hollow elastic part pushes one end of the limiting plate close to the first fixed plate to swing. The swinging of the two limiting plates drives a plurality of pairs of elastic protrusions to enter corresponding first through holes respectively, so as to utilize the elastic protrusions to contact the first through holes, thereby limiting and fixing the positioning rod. Then, through the setting of the limit block and the second through hole, the solution in the second hollow elastic member enters the hydraulic cavity through the second solenoid valve, and the solution in the hydraulic cavity pushes the first slide plate to slide in the hydraulic cavity; the sliding of the first slide plate drives the movement of several limit blocks, and one end of the limit block slides out through the through hole, so that one end of the limit block enters the second through hole, so that the limit block is located in the second through hole, thereby limiting and fixing the positioning rod and the guide rod, which is conducive to improving the limiting and fixing effect between the plug and the socket. Finally, through the setting of the pressure plate and the V-shaped elastic member, the movement of the limit block drives the movement of the pressure plate, and the pressure plate moves to contact the middle part of the V-shaped elastic member, and the two ends of the V-shaped elastic member are respectively in contact with the inner two sides of the elastic protrusion, so that the pressure plate moves to squeeze the V-shaped elastic member, so that the two ends of the V-shaped elastic member support the inner part of the elastic protrusion, which is conducive to strengthening the elastic protrusion and the first through hole to cooperate with the positioning rod to limit and fix, so as to effectively and quickly complete the limiting and fixing of the plug and the socket together, avoiding the risk of one end of the pin being out of contact with the contact member, and the operation is convenient.

[0022] The present invention discloses a micro rectangular electrical connector based on an integrated component. One side of the card block is in sliding contact with the inclined surface of one side of the card slot, and the other side of the card block is in planar contact with the other side of the card slot. The card block cooperates with the card slot and the movable block to limit the second piston plate, and the elastic force of the second spring further limits the second piston plate, thereby improving the stability of the installation of the limiting component between the plug and the socket.

[0051] Specific use of the present invention:

[0052] When installing the plug and the socket, first, the staff aligns one end of the two guide rods 21 with the two positioning grooves 58 respectively, so that one end of the two guide rods 21 slides in the two positioning grooves 58 respectively, so as to make the positioning guides of the plug and the socket close to each other.

[0053] Secondly, when one end of the two guide rods 21 contacts one end of the two positioning grooves 58 respectively, at this time, the first through holes 59 on the positioning rod 57 correspond to the second through holes 60 on the guide rod 21, and one end of the positioning rod 57 contacts one side of the circular plate 22, so that one end of the positioning rod 57 slides in the guide ring 20, so as to slide and contact with the outer side of the positioning rod 57 through the inner side of the guide ring 20, thereby positioning and guiding the movement of the positioning rod 57. The staff pushes the head shell 51 to move, and the movement of the head shell 51 drives the second fixing plate 52 and the two positioning rods 57 to move. The movement of the two positioning rods 57 drives the two guide rods 21 to move respectively, and the movement of the two guide rods 21 drives the two circular plates 22 to move in the two frames 19 respectively. The outer side of the elastic protrusion 27 is pressed and contacted with the outer side of the annular protrusion 23, so that the circular plate 22 can move smoothly in the frame 19, so that one end of the positioning rod 57 can move horizontally in the frame 19 smoothly, which is conducive to the one end of the plurality of pins 56 entering the corresponding connection holes 14. Then, the distance between the two sides of the two limit plates 26 that are close to each other gradually decreases from the side close to the first fixing plate 11 to the side away from the first fixing plate 11, so that the friction force of the annular protrusion 23 and the elastic protrusion 27 gradually increases, further making the circular plate 22 move smoothly in the frame 19, so that one end of the positioning rod 57 can move horizontally in the frame 19 smoothly.

[0054] Next, when one side of the circular plate 22 contacts one end of the push rod 30, the circular plate 22 continues to move to push the push rod 30 and the first piston plate 29 to move. The first piston plate 29 moves to allow the solution in the cylinder 28 to enter the two first hollow elastic members 24 through the two connecting tubes 32. The two first hollow elastic members 24 expand and push the two movable plates 25 to approach each other. The two movable plates 25 approach each other and drive the two limit plates 26 to approach each other. The two limit plates 26 approach each other and drive several pairs of elastic protrusions 27 to approach each other, thereby further increasing the friction force between the annular protrusion 23 and the elastic protrusion 27, which is conducive to making one end of the pin 56 slide steadily in the connecting hole 14, and improving the stability of the installation of the plug and the socket. Among them, the movement of the first piston plate 29 compresses the second spring 31 to generate elastic force.

[0055] Then, when one end of the pin 56 contacts the contact piece 17, the limit assembly is required to limit and fix the plug and the socket together. At this time, the staff pushes the operating rod 44, and the movement of the operating rod 44 drives the second piston plate 61 to move, and the movement of the second piston plate 61 further allows the solution in the cylinder 28 to enter the first hollow elastic piece 24 through the connecting pipe 32; the control system controls the first solenoid valve 33 to open, and the solution in the first hollow elastic piece 24 enters the second hollow elastic piece 35 through the first solenoid valve 33. The expansion of the second hollow elastic piece 35 pushes the end of the limit plate 26 close to the first fixed plate 11 to swing, and the swing of the two limit plates 26 drives several pairs of elastic protrusions 27 to enter the corresponding first through holes 59, so as to use the elastic protrusions 27 to contact the first through holes 59, thereby limiting and fixing the positioning rod 57. The movement of the operating rod 44 drives the movable block 45 to move, and the movable block 45 moves toward the first piston plate 29. At this time, the block 48 slides and contacts with the inclined surface of the slot 49, and the movable block 45 moves to squeeze the block 48, so that the second slide plate 46 slides in the slot 47, and the sliding of the second slide plate 46 compresses the third spring 50 to generate elastic force. When the block 48 contacts the slot 49, under the elastic force of the third spring 50, the second slide plate 46 slides and resets in the slot 47, so that the block 48 re-enters the slot 49. When the movable block 45 moves away from the first piston plate 29, the block 48 contacts with the plane of the slot 49, so as to limit and fix the movable block 45, so as to maintain the position of the second piston plate 61 moving in the cylinder 28. By making one side of the block 48 slide in contact with the inclined surface of one side of the slot 49, and the other side of the block 48 making planar contact with the other side of the slot 49, the block 48 cooperates with the slot 49 and the movable block 45 to limit the second piston plate 61, and the elastic force of the second spring 31 further limits the second piston plate 61, thereby improving the stability of the installation of the limiting component between the plug and the socket.

[0056] Finally, the two limit plates 26 swing so that the two limit plates 26 are parallel to each other. At this time, the solution in the first hollow elastic member 24 continues to enter the second hollow elastic member 35. The control system controls the second solenoid valve 34 to open, and the solution in the second hollow elastic member 35 enters the hydraulic chamber 36 through the second solenoid valve 34. The solution in the hydraulic chamber 36 pushes the first slide plate 37 to slide in the hydraulic chamber 36. The sliding of the first slide plate 37 drives the movement of the plurality of limit blocks 38. One end of the limit block 38 slides out through the through opening 41, so that one end of the limit block 38 enters the second through hole 60, so that the limit block 38 is located in the second through hole 60, thereby limiting and fixing the positioning rod 57 and the guide rod 21, which is conducive to improving the limiting and fixing effect between the plug and the socket. Among them, the sliding of the first slide plate 37 compresses the plurality of first springs 42 to generate elastic force, so that under the elastic force of the plurality of first springs 42, the first slide plate 37 moves and resets. The limiting plate 26 swings to cause the torsion spring 43 to generate elastic force.

[0057] At the same time, the movement of the limit block 38 drives the pressure plate 40 to move, and the pressure plate 40 moves to contact the middle part of the V-shaped elastic member 39, and the two ends of the V-shaped elastic member 39 respectively contact the two sides of the interior of the elastic protrusion 27, so that the pressure plate 40 moves to squeeze the V-shaped elastic member 39, so that the two ends of the V-shaped elastic member 39 support the interior of the elastic protrusion 27, which is beneficial to strengthen the elastic protrusion 27 and the first through hole 59 to cooperate with the positioning rod 57 to limit and fix the positioning rod 57, so as to effectively and quickly complete the limit fixing of the plug and the socket together, avoid the risk of one end of the pin 56 being out of contact with the contact piece 17, and the operation is convenient.

[0058] When the plug and the socket are removed, the staff moves one end of the second slide plate 46 to make the second slide plate 46 slide in the slide groove 47. The movement of the second slide plate 46 drives the movement of several blocks 48, so that the blocks 48 are out of contact with one end of the movable block 45. Then, the staff operates the operating rod 44 to move. The movement of the operating rod 44 drives the second piston plate 61 to move away from the first piston plate 29. The second piston plate 61 moves in the cylinder 28 and draws the solutions in the two first hollow elastic parts 24 back into the cylinder 28 through the two connecting pipes 32. The solution in the second hollow elastic part 35 returns to the first hollow elastic part 24 through the first solenoid valve 33, and the solution in the hydraulic chamber 36 returns to the second hollow elastic part 35 through the second solenoid valve 34. Under the elastic force of the first spring 42, the first slide plate 37 moves and resets. The movement of the first slide plate 37 drives the movement of several limit blocks 38, so that one end of the limit block 38 is out of contact with the second through hole 60. Next, the second hollow elastic member 35 recovers its shape, and under the elastic force of the torsion spring 43, the limit plate 26 swings back to its original position, and the two limit plates 26 swing to make the pairs of elastic protrusions 27 disengage from the two ends of the first through hole 59. Finally, the staff moves the plug and the socket away from each other, so that the plug and the socket are smoothly moved away from each other for removal, thereby facilitating the disassembly of the plug and the socket.

[0059] The present invention is a micro-rectangular electrical connector based on integrated components. Through the arrangement of the elastic protrusion 27 and the annular protrusion 23, the head shell 51 moves to drive the second fixed plate 52 and the two positioning rods 57 to move. The movement of the two positioning rods 57 respectively pushes the two guide rods 21 to move. The movement of the two guide rods 21 drives the two circular plates 22 to move in the two frames 19 respectively. The outer side of the elastic protrusion 27 is squeezed and contacted with the outer side of the annular protrusion 23, so that the circular plate 22 moves smoothly in the frame 19, so that one end of the positioning rod 57 can move smoothly horizontally in the frame 19, which is beneficial to make one end of the pin 56 move smoothly in the connecting hole 14. Then, the distance between the two sides of the two limit plates 26 that are close to each other gradually decreases from the side close to the first fixed plate 11 to the side away from the first fixed plate 11, so that the friction between the annular protrusion 23 and the elastic protrusion 27 gradually increases, and the circular plate 22 is further moved smoothly in the frame 19, so as to further make one end of the positioning rod 57 move horizontally smoothly in the frame 19, thereby improving the stability of the installation of the plug and the socket. Finally, through the arrangement of the first hollow elastic member 24, the cylinder 28, the first piston plate 29, and the push rod 30, the circular plate 22 continues to move to push the push rod 30 and the first piston plate 29 to move, and the first piston plate 29 moves to allow the solution in the cylinder 28 to enter the two first hollow elastic members 24 through the two connecting pipes 32. The expansion of the two first hollow elastic members 24 pushes the two movable plates 25 to approach each other, and the approach of the two movable plates 25 drives the two limit plates 26 to approach each other, and the approach of the two limit plates 26 drives the several pairs of elastic protrusions 27 to approach each other, thereby further increasing the friction force between the annular protrusion 23 and the elastic protrusion 27, which is conducive to making one end of the pin 56 slide smoothly in the connecting hole 14, thereby improving the stability of the installation of the plug and the socket.

[0060] The present invention is a micro-rectangular electrical connector based on integrated components. Through the arrangement of the second hollow elastic member 35, the limiting plate 26, the elastic protrusion 27, and the first through hole 59, the movement of the operating rod 44 drives the second piston plate 61 to move. The movement of the second piston plate 61 further allows the solution in the cylinder 28 to enter the first hollow elastic member 24 through the connecting tube 32; the solution in the first hollow elastic member 24 enters the second hollow elastic member 35 through the first solenoid valve 33; the second hollow elastic member 35 expands and pushes the limiting plate 26 to swing at one end close to the first fixed plate 11. The swinging of the two limiting plates 26 drives several pairs of elastic protrusions 27 to enter the corresponding first through holes 59, so that the elastic protrusions 27 can be used to contact the first through holes 59, thereby limiting and fixing the positioning rod 57. Through the setting of the limit block 38 and the second through hole 60, the solution in the second hollow elastic member 35 enters the hydraulic chamber 36 through the second solenoid valve 34, and the solution in the hydraulic chamber 36 pushes the first slide plate 37 to slide in the hydraulic chamber 36; the sliding of the first slide plate 37 drives the movement of the limit blocks 38, and one end of the limit block 38 slides out through the through hole 41, so that one end of the limit block 38 enters the second through hole 60, so that the limit block 38 is located in the second through hole 60, thereby limiting and fixing the positioning rod 57 and the guide rod 21, which is beneficial to improve the limiting and fixing effect between the plug and the socket. Finally, through the setting of the pressure plate 40 and the V-shaped elastic member 39, the limit block 38 moves to drive the pressure plate 40 to move, and the pressure plate 40 moves to contact the middle part of the V-shaped elastic member 39, and the two ends of the V-shaped elastic member 39 respectively contact the inner two sides of the elastic protrusion 27, so that the pressure plate 40 moves to squeeze the V-shaped elastic member 39, so that the two ends of the V-shaped elastic member 39 support the inner part of the elastic protrusion 27, which is beneficial to strengthen the elastic protrusion 27 and the first through hole 59 to cooperate with the positioning rod 57 to limit and fix the positioning rod 57, so as to effectively and quickly complete the limit fixing of the plug and the socket together, avoid the risk of one end of the pin 56 being out of contact with the contact member 17, and the operation is convenient.

[0061] The present invention is a micro-rectangular electrical connector based on integrated components. One side of the card block 48 is in sliding contact with the inclined surface of one side of the card slot 49, and the other side of the card block 48 is in planar contact with the other side of the card slot 49. The card block 48 cooperates with the card slot 49 and the movable block 45 to limit the second piston plate 61, and the elastic force of the second spring 31 further limits the second piston plate 61, thereby improving the stability of the installation of the limiting component between the plug and the socket.
