[0001] The invention relates to the technical field of wire connection, and in particular to an external force resistant self-locking wire connector. Background Art

[0002] A wire connector is a device that connects the terminals and interfaces of wires or cables to other equipment. It connects two wires or cables together to allow current to flow, thus completing the circuit switching and signal transmission.

[0003] During the use of ordinary wire connectors, the conductor parts of two wires or cables are generally cross-wrapped and bound together. However, in the case of many people and complicated wires, the wires are often pulled by external forces such as human intervention, causing the connections between the wires in the connector to loosen, reducing the stability of the electrical system and possibly leaving safety hazards. In addition, due to insufficient sealing, dust, water vapor and even chemicals may enter the connector, thereby corroding and threatening the connection.

[0007] Furthermore, an inverted V-shaped groove is formed on a side of the pressing block close to the elastic card, and the pressing block is pressed and matched with the elastic card through the inverted V-shaped groove.

[0008] Furthermore, the fixing frame and the clamping plate are both made of rubber material, and the opposite end surfaces of the fixing frame and the clamping plate are configured as corrugated surfaces.

[0010] Furthermore, the rubber baffle ring and the extrusion groove are both configured to be truncated cone-shaped, the diameter of the rubber baffle ring on the side close to the push frame is greater than the diameter of the rubber baffle ring on the side away from the push frame, the diameter of the extrusion groove on the side close to the push frame is greater than the diameter of the extrusion groove on the side away from the push frame, and the lateral length of the extrusion groove is longer than the lateral thickness of the rubber baffle ring, and the outer diameter value of the rubber baffle ring on the side close to the push frame is equal to the diameter value of the adjacent extrusion groove on the side close to the push frame.

[0011] Furthermore, it also includes a push plate symmetrically distributed along the cover plate, the push plate is fixedly connected to the adjacent card block, and the push plate plugs the wire between the fixing frame and the card plate to prevent the wire from being squeezed out.

[0012] Furthermore, it also includes a through nut symmetrically distributed along the connecting plate, the through nut is threadedly connected to the connecting plate, and an annular rubber pad is fixedly connected inside the through nut, and the annular rubber pad is used to protect the wire.

[0013] Furthermore, it also includes a sealing film corresponding to the annular rubber pad, the sealing film is fixedly connected to the corresponding annular rubber pad, the sealing film is set to an elastic material, and the sealing film has an X-shaped opening for the wire to pass through.

[0014] Furthermore, it also includes blocks symmetrically distributed along the rubber stop ring, the blocks are slidably connected to the connecting plate, the rubber stop ring is extrusion-fitted with the blocks, and a first spring is fixedly connected between the blocks and the connecting plate.

[0018] The invention can automatically unlock the cover when it is opened, so that when adjustment and replacement are needed, the operation is simple and quick, and it also ensures that it can automatically return to the original fastened state when it is closed again, which is convenient for maintenance operations.

[0019] The present invention, based on the upper sealing strip and the lower sealing strip, tightens the wires through a tightened rubber retaining ring, thereby further strengthening the sealing of the connector, effectively blocking moisture, dust and other tiny particles from entering the interior, protecting the connection points from corrosion, avoiding loosening of the internal structure due to the intervention of foreign impurities, reducing the risk of loose connection due to foreign matter, and at the same time, improving the stability of the overall connector and alleviating the impact of external force pulling to a certain extent.

[0020] When the cover plate is closed, the push plate pushes the wire downward, thereby ensuring that the wire is limited between the connecting plate, the fixing frame, the clamping plate and the push plate, and preventing the wire from being squeezed upward during clamping, resulting in the wire not being clamped in place.

DETAILED DESCRIPTION

[0034] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Embodiment 1: A self-locking wire connector resistant to external forces, combined with an attached Figure 1 To Attachment Figure 5, including a connecting plate 1, a placement groove is opened in the connecting plate 1, and two left and right wires 101 are placed in the placement groove of the connecting plate 1, a cover plate 2 is placed on the top of the connecting plate 1 by a clamping method, and the connecting plate 1 and the cover plate 2 are fixed by six bolts 201, a fixing frame 3 is fixedly connected in the middle of the placement groove of the connecting plate 1, and the left and right sides of the fixing frame 3 are both set as corrugated surfaces, and the upper part of the fixing frame 3 is fixedly connected with an elastic card 4 symmetrically distributed along the front and back of the fixing frame 3, and the elastic card 4 is used to lock the conductor part of the wire 101, and a pressing block 5 is fixedly connected in the middle of the bottom of the cover plate 2, and an inverted V-shaped groove is opened on the bottom side of the pressing block 5. The pressing block 5 is squeezed and matched with the elastic card 4 through the inverted V-shaped groove, so that the two elastic cards 4 are bent toward the side close to each other, thereby pressing the conductor part of the wire 101, and the bottom of the cover plate 2 is fixedly connected with a card block 6 symmetrically distributed along the front and back of the pressing block 5, and a card plate 7 symmetrically distributed along the front and back of the fixing frame 3 is slidably connected in the placement groove of the connecting plate 1. After the conductor of the wire 101 passes through between the two elastic cards 4, it is bent and passed in the opposite direction between the fixing frame 3 and the card plate 7. The card plate 7 then slides horizontally to the side close to the fixing frame 3 to perform secondary locking on the conductor part of the wire 101. The fixing frame 3 and the card plate 7 are both made of rubber, and the end face of the card plate 7 close to the fixing frame 3 is also set as a corrugated surface to provide multi-point contact pressure so that the pressing force is evenly distributed on the wire 101. The lower sealing strip 8 symmetrically distributed along the front and back of the connecting plate 1 is embedded and fixedly connected in the connecting plate 1, and the upper sealing strip 9 symmetrically distributed along the front and back of the cover plate 2 is embedded and fixedly connected in the cover plate 2. The insulator part of the wire 101 is covered with a rubber retaining ring 10. When the cover plate 2 is covered on the connecting plate 1, the upper sealing strip 9 and the lower sealing strip 8 are in contact to seal the gap between the connecting plate 1 and the cover plate 2. The rubber retaining ring 10 seals the gap between the connecting plate 1 and the wire 101 and the gap between the cover plate 2 and the wire 101.

[0036] Rubber retaining rings 10 are put on the insulators of the two wires 101 to be connected, and the two wires 101 are respectively placed in the placement grooves on the left and right sides of the connecting plate 1, and the conductors of the wires 101 pass through the two elastic cards 4, and the conductor ends of the wires 101 are bent in a U shape and wrapped around the adjacent fixing frame 3 and the card plate 7. In this way, the contact connection of the two wires 101 is achieved. Then, the cover plate 2 is covered on the top of the connecting plate 1, and the cover plate 2 drives the pressure block 5 to squeeze the elastic card 4 downward, so that the elastic card 4 clamps the conductors of the two wires 101. At the same time, the cover plate 2 drives the card block 6 to squeeze the card plate 7 downward, so that the card plate 7 slides to the side of the fixing frame 3, thereby clamping the conductor ends of the wires 101. When the cover plate 2 is covered, the upper sealing strip 9 corresponds to the lower sealing strip 8 and is close to each other. Finally, the cover plate 2 is locked on the connecting plate 1 by the bolt 201.

[0037] In summary, the present invention fixes the cover plate 2 on the connecting plate 1 through bolts 201, so as to achieve the connection and self-locking of the two wires 101. In this way, during the installation process, there is no need for repeated manual adjustments, and the most suitable tightening degree can be automatically matched according to the thickness of the cable, which is both convenient and can ensure the stability of the connection.

[0038] The present invention can provide multi-point contact pressure through the corrugated fixing frame 3 and the clamping plate 7, which is evenly distributed on the wire 101. Even if it is pulled by external force, it can maintain a good wire holding force and reduce the risk of loosening.

[0039] The present invention can automatically unlock the cover plate 2 when it is opened, so that when adjustment or replacement is required, the operation is simple and quick, and it also ensures that it can automatically return to the original fastened state when it is closed again, which is convenient for maintenance operations.

[0040] Embodiment 2: Based on embodiment 1, Figure 3 To Attachment Figure 5 , and also includes a push plate 131 symmetrically distributed along the front and rear of the cover plate 2. The push plate 131 is fixedly connected to the adjacent card block 6. The width between the front and rear of the push plate 131 is smaller than the distance between the fixing frame 3 and the card plate 7, so as to avoid affecting the card plate 7 to approach one side of the fixing frame 3, thereby avoiding affecting the card plate 7 to clamp the wire 101. When the cover plate 2 is covered, the push plate 131 presses the wire 101 downward, so that the wire 101 is stuck between the fixing frame 3 and the card plate 7, to prevent the wire 101 from being squeezed out during clamping.

[0041] When the cover plate 2 is put on so that the clamping plate 7 clamps the wire 101, the cover plate 2 simultaneously drives the push plate 131 to poke the wire 101 downward, so that the wire 101 can be limited between the connecting plate 1, the fixing frame 3, the clamping plate 7 and the push plate 131, thereby preventing the wire 101 from being squeezed upward during clamping, resulting in the wire 101 not being clamped in place.

[0042] Combined with Figure 4 and attached Figure 5 , and also includes a slide plate 19 corresponding to the bolt 201. The slide plate 19 is slidably connected to the connecting plate 1. When the bolt 201 is tightened between the cover plate 2 and the connecting plate 1, the slide plate 19 contacts the end of the bolt 201, and a second spring 20 is fixedly connected between the slide plate 19 and the connecting plate 1.

[0043] When the bolt 201 is screwed in downward, the slide plate 19 slides downward under the action of the bolt 201, and the second spring 20 is compressed. When the bolt 201 is tightened, the reaction force of the second spring 20 causes the bolt 201 to be subjected to an upward reaction force, and the bolt 201 is pushed upward and tightened in the thread groove matching it, so that the bolt 201 is more tightly bolted between the connecting plate 1 and the cover plate 2, thereby preventing the bolt 201 from loosening and avoiding sealing failure.

[0044] Embodiment 3: Based on Embodiment 2, Figure 6 and attached Figure 7 , and also includes guide blocks 11 symmetrically distributed along the card plate 7, the guide blocks 11 are fixedly connected to the adjacent card plate 7, and a push frame 12 corresponding to the guide block 11 is slidably connected to the connecting plate 1 along the left and right directions, one end of the push frame 12 is extruded and matched with the corresponding guide block 11, and the other end of the push frame 12 is in contact with the adjacent rubber retaining ring 10, and the connecting plate 1 is provided with extrusion grooves 13 symmetrically distributed along the connecting plate 1, and the push frame 12 is used to push the rubber retaining ring 10 to slide in the adjacent extrusion groove 13, and the rubber retaining ring 10 and the extrusion groove 13 are both set to a truncated cone shape, the diameter of the rubber retaining ring 10 on the side close to the push frame 12 is greater than the diameter of the rubber retaining ring 10 on the side away from the push frame 12, the diameter of the extrusion groove 13 on the side close to the push frame 12 is greater than the diameter of the extrusion groove 13 on the side away from the push frame 12, and the length between the left and right sides of the extrusion groove 13 is longer than the length between the left and right sides of the rubber retaining ring 10, and the outer diameter value of the rubber retaining ring 10 on the side close to the push frame 12 is equal to the diameter value of the adjacent extrusion groove 13 on the side close to the push frame 12.

[0045] When the card plate 7 slides toward the side of the fixing frame 3, the card plate 7 slides toward the side of the adjacent rubber retaining ring 10 through the inclined surface of the guide block 11 to squeeze the push frame 12, and the push frame 12 pushes the rubber retaining ring 10 to slide toward the side away from the card plate 7, so that the rubber retaining ring 10 is pushed to the side with a smaller diameter value of the extrusion groove 13. Under the extrusion action of the extrusion groove 13, the rubber retaining ring 10 changes from a relaxed state to a tightened state, so that the wire 101 is tightened by the tightened rubber retaining ring 10. On the basis of the upper sealing strip 9 and the lower sealing strip 8, the sealing of the connector is further strengthened, effectively blocking moisture, dust and other tiny particles from entering the interior, protecting the connection point from corrosion, avoiding the looseness of the internal structure due to the intervention of foreign impurities, reducing the risk of loose connection due to foreign matter, and at the same time, improving the stability of the overall connector, to a certain extent, reducing the impact of external force pulling.

[0046] Combined with Figure 8 , and also includes a through nut 14 symmetrically distributed along the connecting plate 1. The through nut 14 is threadedly connected to the connecting plate 1. An annular rubber pad 15 is fixedly connected inside the through nut 14. The annular rubber pad 15 is used to protect the wire 101 and reduce the wear of the wire 101. One end of the annular rubber pad 15 is fixedly connected to a sealing film 16. The sealing film 16 is set to an elastic material. The sealing film 16 has an X-shaped opening for the wire 101 to pass through.

[0047] Since the wire 101 will be worn by the connecting plate 1 for a long time at the entrance of the connecting plate 1, which may cause the wire 101 to break, to prevent this situation, the present invention allows the wire 101 to pass through the annular rubber pad 15 and the sealing film 16 in the middle of the through nut 14, so that the through nut 14 is put on the wire 101 near the entrance of the connecting plate 1, and the through nut 14 is screwed on at the entrance of the connecting plate 1. In this way, the wear of the wire 101 can be prevented at the entrance, and the sealing of the connector can be increased.

[0048] Combined with Fig. 9 , and also includes a block 17 symmetrically distributed along the front and back of the rubber block ring 10, the block 17 is slidably connected to the connecting plate 1, the rubber block ring 10 and the block 17 are squeezed together, and a first spring 18 is fixedly connected between the block 17 and the connecting plate 1.

[0049] In the process of placing the wire 101 with the rubber baffle ring 10 in the placement groove of the connecting plate 1, in order to prevent the rubber baffle ring 10 from being tilted, the rubber baffle ring 10 needs to be fixed so that it can be placed better in the early stage. Specifically: during the lowering process of the rubber baffle ring 10, the baffle block 17 will be squeezed to slide toward the side close to the adjacent first spring 18, and the first spring 18 will be compressed until the rubber baffle ring 10 is completely vertically placed in the extrusion groove 13. At this time, the rubber baffle ring 10 is vertically limited between the baffle block 17 and the connecting plate 1 by the elastic force of the first spring 18. When the wire 101 is removed, the first spring 18 is reset to drive the baffle block 17 to slide in the opposite direction and reset.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
