Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a connector and circuit connection device. Background Technology

[0002] Connectors, also known as plugs or connectors, are mainly used to provide convenient electrical plug-in connections in electronic products, power equipment, etc., which greatly improves the efficiency of electronic product production and maintenance. Their functions include realizing electrical connections to ensure the smooth transmission of current between devices; transmitting various types of signals, such as data signals, audio signals, and video signals; and fixing devices or components together through physical connections to provide mechanical support and stability.

[0003] Existing connectors typically use a plug-in method for circuit connection. However, after the connector is connected to the wire, there are still gaps at the plug-in point. When exposed to rain or water vapor, water can easily enter through these gaps, causing short circuits. The lack of an effective sealing and waterproof structure poses certain safety hazards. Furthermore, the connection lacks additional fixation, making the connection unstable. Wires are also prone to falling off due to external dragging. Therefore, we propose a connector and circuit connection device to address the shortcomings of existing methods. Utility Model Content

[0004] Technical problems to be solved

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a connector and circuit connection device that can achieve a sealing and waterproof effect after the connector and wire are connected, preventing rainwater or water vapor from entering through the gaps. At the same time, it can provide additional fixation to prevent the wire from falling off due to external dragging, thereby facilitating the user's operation.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connector and circuit connection device, comprising a connector housing, two connector heads fixedly connected to the outer side of the connector housing, a contact element fixedly connected inside the connector head, an inflatable sealing ring fixedly connected to the inner wall of the connector head, an airbag fixedly connected to the top of the connector head, a spring fixedly connected between the upper and lower inner walls of the airbag, a guide tube fixedly connected to the outer side of the spring, the bottom end of the guide tube fixedly connected to the outer side of the inflatable sealing ring, a pressing component provided on one side of the airbag, and a reinforcing component provided on the outer side of the connector head.

[0008] The present invention is further configured such that the pressing component includes a fixing plate and a groove, the bottom end of the fixing plate is fixedly connected to the outside of the connector, and the groove is formed inside the fixing plate.

[0009] The present invention is further configured such that the pressing assembly includes a screw and a knob, the bottom of the screw being rotatably connected to the inner bottom of the groove, and the bottom end of the knob being fixedly connected to the top end of the screw.

[0010] The present invention is further configured such that the pressing assembly includes a connecting plate and a pressing plate, the inner wall of the connecting plate is threaded to the outer side of the screw, the two sides of the connecting plate are fitted with the inner wall of the groove, the outer side of the pressing plate is fixedly connected to one end of the connecting plate, and the bottom of the pressing plate is fitted with the top of the airbag.

[0011] The present invention is further configured such that the reinforcing component includes a mounting plate and a rotating rod, wherein there are two mounting plates, the mounting plates are fixedly connected to the outer ends of the connector, and the outer side of the rotating rod is rotatably connected to the inner wall of the mounting plate.

[0012] The present invention is further configured such that the reinforcing component includes a roller, an arc-shaped clamping plate, and an anti-slip pad. The outer side of the roller is rotatably connected to one end of the rotating rod, the outer side of the arc-shaped clamping plate is fixedly connected to the other end of the rotating rod, and the outer side of the anti-slip pad is fixedly connected to the inner wall of the arc-shaped clamping plate.

[0013] The present invention is further configured such that the reinforcing component includes a screw groove, a movable sleeve, and a conical sleeve. The screw groove is formed on the outer side of the connector. The inner wall of the movable sleeve is threadedly connected to the outer side of the connector through the screw groove. The inner wall of the conical sleeve is fixedly connected to the outer side of the movable sleeve. The outer inclined surface of the conical sleeve is in contact with the outer side of the roller.

[0014] Beneficial effects:

[0015] I. This utility model, through its designed pressing component, can seal the connection between the connector and the wire. By rotating the knob, the screw rotates, which, in conjunction with the groove, limits the connection plate, causing it to move downwards. This, in turn, causes the pressing plate to move downwards, compressing the airbag and deforming the airbag and spring. During the deformation process, the air inside the airbag flows into the guide tube and then into the inflatable sealing ring, causing the inflatable sealing ring to expand and achieve a sealing effect, preventing rainwater or water vapor from entering through gaps and improving safety.

[0016] Second, this utility model provides additional fixation through the reinforcement components. After the wire is inserted into the connector, the operator can rotate the movable sleeve. Since the movable sleeve is connected to the outer thread of the connector through the screw groove, the movable sleeve can move horizontally, which in turn drives the tapered sleeve to move horizontally. The inclined part of the tapered sleeve pushes the roller to move, which in turn makes the rotating rod rotate on the mounting plate, causing the arc-shaped clamping plate to move towards the wire. This can drive both arc-shaped clamping plates to move towards the wire at the same time, clamping and fixing the wire, providing additional fixation and preventing the wire from easily falling off due to external dragging.

[0017] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution: a connector and circuit connection device, including a connector housing 1, two connector heads 2 are fixedly connected to the outer side of the connector housing 1, a contact 3 is fixedly connected to the inside of the connector head 2, an inflatable sealing ring 4 is fixedly connected to the inner wall of the connector head 2, an airbag 5 is fixedly connected to the top of the connector head 2, a spring 6 is fixedly connected between the inner walls of the upper and lower sides of the airbag 5, a guide tube 7 is fixedly connected to the outer side of the spring 6, the bottom end of the guide tube 7 is fixedly connected to the outer side of the inflatable sealing ring 4, a pressing component 8 is provided on one side of the airbag 5, and a reinforcing component 9 is provided on the outer side of the connector head 2;

[0026] The wire is inserted into the inside of the connector 2 for circuit connection. The airbag 5 is squeezed by the pressing component 8, causing the airbag 5 and spring 6 to deform. During the deformation, the air in the airbag 5 flows into the guide tube 7 and then into the inflation sealing ring 4, which in turn causes the inflation sealing ring 4 to expand and seal the connection between the connector 2 and the wire, preventing rainwater or water vapor from entering from the gaps. The reinforcement component 9 provides additional fixation to prevent the wire from falling off easily due to external dragging.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the pressing assembly 8 includes a fixing plate 801, a groove 802, a screw 803, a knob 804, a connecting plate 805, and a pressing plate 806. The bottom end of the fixing plate 801 is fixedly connected to the outside of the connector 2. The groove 802 is formed inside the fixing plate 801. The bottom of the screw 803 is rotatably connected to the inner bottom of the groove 802. The bottom end of the knob 804 is fixedly connected to the top end of the screw 803. The inner wall of the connecting plate 805 is threadedly connected to the outside of the screw 803. Both sides of the connecting plate 805 are in contact with the inner wall of the groove 802. The outer side of the pressing plate 806 is fixedly connected to one end of the connecting plate 805. The bottom of the pressing plate 806 is in contact with the top end of the airbag 5.

[0028] By rotating the knob 804, the screw 803 is rotated, which, in conjunction with the groove 802, limits the connection plate 805. This causes the connection plate 805 to move downward, which in turn causes the pressing plate 806 to move downward, compressing the airbag 5 and causing the airbag 5 and spring 6 to deform. During the deformation process, the air in the airbag 5 flows into the guide tube 7 and then into the inflation sealing ring 4, which in turn causes the inflation sealing ring 4 to expand and seal the connection between the connector 2 and the wire.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, the reinforcement component 9 includes a mounting plate 901, a rotating rod 902, a roller 903, an arc-shaped clamping plate 904, an anti-slip pad 905, a screw groove 906, a movable sleeve 907, and a conical sleeve 908. There are two mounting plates 901. The mounting plates 901 are fixedly connected to the outer ends of the connector 2. The outer side of the rotating rod 902 is rotatably connected to the inner wall of the mounting plate 901. The outer side of the roller 903 is rotatably connected to one end of the rotating rod 902. The outer side of the arc-shaped clamping plate 904 is fixedly connected to the other end of the rotating rod 902. The outer side of the anti-slip pad 905 is fixedly connected to the inner wall of the arc-shaped clamping plate 904. The screw groove 906 is opened on the outer side of the connector 2. The inner wall of the movable sleeve 907 is threadedly connected to the outer side of the connector 2 through the screw groove 906. The inner wall of the conical sleeve 908 is fixedly connected to the outer side of the movable sleeve 907. The outer inclined surface of the conical sleeve 908 fits against the outer side of the roller 903.

[0030] By rotating the movable sleeve 907, which is connected to the outer thread of the connector 2 via the screw groove 906, the movable sleeve 907 can move horizontally, which in turn drives the tapered sleeve 908 to move horizontally. This causes the inclined part of the tapered sleeve 908 to push the roller 903 to move, thereby causing the rotating rod 902 to rotate on the mounting plate 901. This causes the two arc-shaped clamping plates 904 to move closer to each other, clamping and fixing the wire.

[0031] Working principle: During use, the wire is inserted into the inside of the connector 2 for circuit connection. After connection, when it is necessary to seal the gap between the two, the screw 803 is rotated by turning the knob 804. The groove 802 limits the connection plate 805, which can drive the connection plate 805 to move downward, thereby driving the pressing plate 806 to move downward, compressing the airbag 5, causing the airbag 5 and spring 6 to deform. During the deformation process, the air in the airbag 5 flows into the guide tube 7, and then into the inflation sealing ring 4, causing the inflation sealing ring 4 to expand and seal the connection between the connector 2 and the wire. This can achieve a sealing and waterproof effect, preventing rainwater or water vapor from entering from the gap.

[0032] After the wire is inserted into the connector 2, the operator rotates the movable sleeve 907. Since the movable sleeve 907 is connected to the outer thread of the connector 2 through the screw groove 906, the movable sleeve 907 can move horizontally, which in turn drives the tapered sleeve 908 to move horizontally. The inclined part of the tapered sleeve 908 pushes the roller 903 to move, which in turn causes the rotating rod 902 to rotate on the mounting plate 901, driving the arc-shaped clamping plate 904 to move towards the wire. This allows the two arc-shaped clamping plates 904 to move closer to each other, clamping and fixing the wire. This provides additional fixation and prevents the wire from easily falling off due to external dragging. The anti-slip pad 905 increases the friction between the arc-shaped clamping plate 904 and the wire, improving the fixing effect.

[0033] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
