Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to an electrical connector with anti-mis-mating features. Background Technology

[0002] An electrical connector is a device used to connect two or more electrical devices, circuits or components to enable the transmission and exchange of electrical signals or power.

[0003] An existing patent (publication number: CN208923510U) discloses an electrical connector, including a plug and a socket. The plug has a plug block on one side, with multiple mounting holes inside the plug block. Each mounting hole contains a pin. The socket has a socket that mates with the plug block, with multiple pins inside the socket. Each pin has a socket that mates with a pin. An inner sealing ring is fitted onto the bottom end of each pin within the socket. When the plug and socket are connected, the plug block and pins are inserted into the socket, and the end face of the plug block extending into the socket abuts against the inner sealing ring. The electrical connector provided by this invention features good sealing performance and low production cost.

[0004] The aforementioned connectors have the advantages of good sealing effect and low production cost during use. However, they lack the ability to prevent mis-mating. During use, mis-mating often occurs, which can damage the connector. Therefore, there is an urgent need for an electrical connector with anti-mis-mating features to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrical connector with anti-misinsertion features, which has advantages such as error prevention and improved sealing, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrical connector with anti-misinsertion features, comprising a plug and a plurality of rectangular blocks and pins fixedly connected to one end of the plug, and a socket and a plurality of socket holes and rectangular slots opened at one end of the socket, wherein a positioning component is provided at one end of the socket for positioning the pins and preventing the pins from being damaged by misinsertion.

[0007] One end of the socket is provided with a sliding fastening and sealing component, which is used to automatically seal the connection when the plug and socket are inserted.

[0008] Furthermore, the positioning component includes a fixed frame that slides onto the outer surface of the socket, a sealing ring is provided between the socket and the fixed frame, a positioning plate is rotatably connected to the inner wall of the fixed frame, and multiple plugs and rectangular blocks pass through the positioning plate and are respectively inserted into their corresponding sockets and rectangular slots. A torsion spring is fixedly connected to the left side of the positioning plate along the axial direction of the socket, and the other end of the torsion spring is fixedly connected to the inner wall of the fixed frame.

[0009] Through the above scheme, the torsion spring in the compressed state can provide a restoring force for the positioning plate. After the plug is pulled out, the positioning plate can automatically return to the initial position, thereby sealing the socket and preventing misinsertion during the next insertion process.

[0010] Furthermore, the inner wall of the positioning disk is convex and slides into the outer surface of the plug.

[0011] With the above solution, the protruding part of the positioning plate can drive the positioning plate to rotate during the rotation of the plug, so that the rectangular block corresponds to the position of the rectangular groove.

[0012] Furthermore, the fastening and sealing assembly includes a sealing ring fitted onto the outer surface of the plug along its axial direction. Multiple circumferentially distributed extrusion members are slidably inserted into the inner wall of the right side of the fixing frame along its axial direction, each extrusion member contacting the sealing ring. Multiple circumferentially distributed notches are provided on the inner wall of the fixing frame. A rotating frame is fixedly connected to the outer surface of the positioning disc, and the rotating frame is slidably connected along the inner walls of the multiple notches. Multiple pressure blocks are fixedly connected to the inner wall of one end of the rotating frame along its axial direction, each pressure block contacting its adjacent extrusion member.

[0013] The above solution allows for the compression of the sealing ring during the connection between the plug and socket. This compression fills the gap between the fixed frame and the plug, improving the sealing performance between the plug and socket and locking them together to prevent separation.

[0014] Furthermore, each of the pressure blocks is chamfered, and the end of each extrusion member away from the plug is spherical.

[0015] The above scheme, which involves chamfering the pressure block and making one end of the extrusion part spherical, reduces the resistance when the two come into contact, allowing them to make stable contact.

[0016] Furthermore, each of the extrusion members is arc-shaped at the end near the sealing ring to increase the contact area with the sealing ring.

[0017] With the above solution, the end of the extruder near the sealing ring is made into an arc shape, which can better contact the sealing ring and increase the contact area with the sealing ring. This allows the pressure of the extruder to be better applied to the sealing ring, so that the sealing ring can fill the connection between the plug and the fixed frame after being compressed.

[0018] Furthermore, the inner wall of the fixed frame and the outer surface of the plug are both provided with threaded grooves. One end of the plug is slidably fitted with a threaded connector and a second sealing ring along its axial direction. The threaded connector is threadedly connected to the two threaded grooves, and the second sealing ring is located between the threaded connector and the rotating frame.

[0019] The above solution, by setting a second sealing ring, can further improve the sealing performance of the plug and socket connection, preventing external moisture from entering the connection between the plug and socket.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This type of electrical connector with anti-misinsertion design uses a positioning plate. During the plug and socket connection process, a rectangular block needs to be inserted into the position corresponding to the rectangular slot on the positioning plate first. Then, the positioning plate is rotated to position the rectangular block and the rectangular slot. After that, the plug and socket are plugged together, and the pins will be inserted into the corresponding sockets to achieve plug and socket connection. Since the positioning plate will seal the position of the sockets during the connection process, it can prevent the occurrence of errors.

[0022] When the plug and socket are connected, the extrusion component can compress the sealing ring, causing the sealing ring to deform and fill the connection between the plug and the fixed frame, thereby sealing the connection between the plug and the socket and improving the sealing performance. At the same time, the plug and socket can also be locked to prevent them from separating. Attached Figure Description

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please see Figures 1-9 The electrical connector with anti-misinsertion feature in this embodiment includes a plug 1 and multiple rectangular blocks 2 and pins 3 fixedly connected to one end of the plug 1, as well as a socket 4 and multiple socket holes 5 and rectangular slots 6 opened at one end of the socket 4. A positioning component 7 is provided at one end of the socket 4 to position the pins 3 and prevent the pins 3 from being damaged by misinsertion.

[0040] One end of the socket 4 is provided with a sliding fastening and sealing component 8, which is used to automatically seal the connection when the plug 1 is inserted into the socket 4.

[0041] The positioning assembly 7 includes a fixed frame 703 that slides onto the outer surface of the socket 4. A sealing ring 704 is provided between the socket 4 and the fixed frame 703. A positioning disk 701 is rotatably connected to the inner wall of the fixed frame 703. The slot on the positioning disk 701 has the same shape as the socket 5 and the rectangular slot 6. Multiple plugs 1 and rectangular blocks 2 pass through the positioning disk 701 and are respectively inserted into their corresponding sockets 5 and rectangular slots 6. A torsion spring 702 is fixedly connected to the left side of the positioning disk 701 along the axial direction of the socket 4. The torsion spring 702 is in a compressed state. The other end of 2 is fixedly connected to the inner wall of the fixed frame 703. The torsion spring 702 in the compressed state can provide a reset force for the positioning plate 701. After the plug 1 is pulled out, the positioning plate 701 can automatically return to the initial position, thereby sealing the socket 5 and preventing misinsertion during the next insertion process. The inner wall of the positioning plate 701 is convex and slides into the outer surface of the plug 1. The convex part of the positioning plate 701 can drive the positioning plate 701 to rotate during the rotation of the plug 1, so that the position of the rectangular block 2 corresponds to that of the rectangular groove 6.

[0042] The fastening and sealing assembly 8 includes a sealing ring 801 fitted onto the outer surface of the plug 1 along its axial direction. A plurality of circumferentially distributed extrusion parts 802 are slidably inserted into the inner wall of the right side of the fixing frame 703 along its axial direction. Each extrusion part 802 contacts the sealing ring 801. A plurality of circumferentially distributed notches 803 are provided on the inner wall of the fixing frame 703. A rotating frame 804 is fixedly connected to the outer surface of the positioning plate 701. The rotating frame 804 is slidably connected along the inner wall of the plurality of notches 803. A plurality of pressure blocks 805 are fixedly connected to the inner wall of one end of the rotating frame 804 along its axial direction. Each pressure block 805 is adjacent to an extrusion part 802. The pressure element 802 contacts the plug 1 and socket 4. By setting the pressure element 802, the sealing ring 801 can be squeezed during the connection of the plug 1 and socket 4. After being compressed, the sealing ring 801 fills the gap between the fixing frame 703 and the plug 1, thereby improving the sealing performance of the plug 1 and socket 4 and locking the plug 1 and socket 4 to prevent them from separating. Each pressure block 805 is chamfered, and the end of each pressure element 802 away from the plug 1 is spherical. The chamfering of the pressure block 805 and the spherical end of the pressure element 802 can reduce the resistance when the two are in contact, so that the two can be in stable contact.

[0043] Each extrusion piece 802 has an arc-shaped end near the sealing ring to increase the contact area with the sealing ring 801. The arc shape of the extrusion piece 802 near the sealing ring allows for better contact with the sealing ring 801, thereby increasing the contact area and allowing the pressure of the extrusion piece 802 to be better applied to the sealing ring 801. This allows the sealing ring 801 to fill the connection between the plug 1 and the fixing frame 703 after being compressed. The inner wall of the fixing frame 703 and the outer surface of the plug 1 are both provided with threaded grooves 9. One end of the plug 1 is slidably fitted with a threaded connector 10 and a second sealing ring 11 along its axial direction. The threaded connector 10 is threadedly connected to the two threaded grooves 9. The second sealing ring 11 is located between the threaded connector 10 and the rotating frame 804. By setting the second sealing ring 11, the sealing performance at the connection between the plug 1 and the socket 4 can be further improved, preventing external moisture from entering the connection between the plug 1 and the socket 4.

[0044] The working principle of the above embodiment is as follows: When plug 1 and socket 4 are connected, the rectangular block 2 on plug 1 is inserted into the slot on positioning plate 701 inside fixed frame 703 that corresponds to the shape of rectangular groove 6. Then, plug 1 is rotated. Since there is a protrusion on the inner wall of positioning plate 701, positioning plate 701 will rotate with plug 1, so that rectangular block 2 corresponds to rectangular groove 6. At this time, socket 4 is slid so that plug 1 is inserted into socket 4. The pin 3 on plug 1 will enter the corresponding socket 5. The sealing ring 704 can seal between fixed frame 703 and socket 4 to prevent external moisture from entering. When the plug is inserted into socket 4, the positioning plate 701 will block the socket 5 when it is reset, thus preventing misinsertion. When the positioning plate 701 rotates, it will drive the rotating frame 804 to rotate and cause the pressure block 805 to push the extrusion member 802 to slide. The extrusion member 802 will transfer pressure to the sealing ring 801, so that the sealing ring 801 can be deformed under pressure and fill the connection between the plug 1 and the fixed frame 703, improving the sealing between the two. Then, the fixed frame 703 and the plug 1 are connected by the threaded connector 10, further improving the sealing between the two.
