[0010] On the basis of the above scheme: the installation groove is adapted to the guide ring through threads, the embedding groove and the clamping block are clamped together, the clamping cylinder and the column terminal are plugged together, and the clamping column and the slot are clamped together.

[0011] A better solution among the above solutions is: the end of the reinforcement mechanism is fixedly connected with a fixing tube, and the top of the fixing tube is connected with a buffer ring through a thread, the buffer ring has a guide hole built in it, and a limiting ring is bonded in the guide hole, and grooves are provided around the limiting ring.

[0012] As a further solution of the present invention: a receiving ring is welded on the inner circumference of the connecting ring, and the inner ring of the receiving ring is provided with a receiving groove, and an internal threaded ring is welded on the inner circumference of the end face of the receiving ring.

[0013] At the same time, the reinforcement mechanism includes an installation ring, an expansion ring, a sealing ring, an external thread ring, a conductive sheet, a connecting wire, a fitting groove, a support ring and an insulating ring, and the insulating ring is bonded to the inner circumference of the fixed cylinder, and there is a gap between the limiting ring and the insulating ring, and an elastic component is movably connected in the gap.

[0014] As a preferred embodiment of the present invention: the support ring is connected to the bottom circumference of the fixing cylinder by threads, the mounting ring is connected to the outer circumference of the support ring by threads, and a fitting groove is opened between the mounting ring and the support ring, the fitting groove is adapted to the receiving ring, the expansion ring is bonded to the bottom circumference of the support ring, and the external threaded ring is fixedly connected to the bottom circumference of the insulating ring.

[0017] The beneficial effects of the present invention are:

[0018] 1. This kind of electrical connector with safety and anti-open circuit, when installing, first glue the insulating ring into the fixed tube, and let the elastic component be located above the circumference of the insulating ring, then fix the support ring to the outer circumference of the fixed tube through threads, and at the same time, connect the installation ring to the outer circumference of the support ring through threads, and glue the expansion ring to the bottom of the support ring, weld the conductive sheet to the inner circumference of the external thread ring, and weld the top of the external thread ring to the bottom of the insulating ring, then pass the connecting wire through the conductive sheet, and pass the end of the wire through the elastic component, then connect the buffer ring to the top inner circumference of the fixed tube through threads, so that a gap is formed between the buffer ring and the insulating ring, and let the elastic component be located in the gap, then, snap the storage ring into place The socket is inserted into the groove and the connecting ring is rotated so that the internal thread ring in the receiving ring is connected to the external thread ring. Therefore, the nested connection structure between the rings not only ensures the connection stability of the components in the socket, but also there is a certain gap or void between the rings, which plays a role in buffering and absorbing impact force, and reduces the impact of the impact on the structure. At the same time, the impact force is dispersed and transmitted between the rings, so that the impact force is dispersed and mitigated, reducing the impact pressure on the overall structure and improving the impact resistance of the structure.

At the same time, the clamping column is clamped in the slot to achieve a stable connection, and the clamping block and the embedded groove are plugged and fitted to each other, thereby achieving a tight connection between the plug and the socket, avoiding poor circuit contact or open circuit failure due to looseness between the two, and can reduce the impedance of electrical contact, reduce the resistance to current transmission, reduce the risk of heat and fire, and improve the safety of electrical equipment.

[0020] 3. This is a safe electrical connector that prevents open circuits. When the fixing tube is hit by external force, the connecting wires in the clamping ring located in the gap can adjust the distance between the connecting wires through the triangular spring pieces, the wavy spring pieces and the diamond-shaped stretching ring. This can not only reduce the vibration and friction between the connecting wires and protect the connecting wires from external impact or damage, but also play a certain buffering role, thereby improving the anti-interference ability of the connecting wire system.

[0021] 4. This is a safe electrical connector that prevents open circuits. The connection between the grooves around the limit ring and the connecting wires prevents the cables from contacting or getting entangled with each other, reduces electromagnetic interference and signal interference, and maintains the stability of the electrical connection.

[0035] In order to promote the close docking between the socket 1 and the plug 2; Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a mounting groove 105 is formed at one end of the stabilizing ring 103, and an embedding groove 107 is formed near the inner side of the mounting groove 105 of the stabilizing ring 103, and an annular clamping sleeve 108 is formed in the embedding groove 107, a guide wire 1081 is welded to the bottom end of the clamping sleeve 108, and a clamping column 106 is formed on the end surface of the stabilizing ring 103 near the circumference of the embedding groove 107;

[0036] The end of the plug 2 is connected to a mounting barrel 202 by a thread, and a guide ring 206 is provided at the end of the mounting barrel 202.

[0039] In order to maintain the stability of the electrical connection, the tolerance performance of the socket 1 is improved; Figure 5 and Figure 6 As shown, the end of the reinforcement mechanism 101 is fixedly connected with a fixing tube 109, and the top of the fixing tube 109 is threadedly connected with a buffer ring 10109, the buffer ring 10109 has a guide hole 1092 built in, and a limiting ring 1091 is bonded in the guide hole 1092, and grooves are provided around the limiting ring 1091.

[0040] The inner circumference of the connecting ring 104 is welded with a receiving ring 1041, and the inner ring of the receiving ring 1041 is provided with a receiving groove 1042, and the inner circumference of the end surface of the receiving ring 1041 is welded with an internal thread ring 1043;

[0041] The reinforcement mechanism 101 includes a mounting ring 10101, an expansion ring 10102, a sealing ring 10103, an external thread ring 10104, a conductive sheet 10105, a connecting wire 10106, a fitting groove 10107, a support ring 10108 and an insulating ring 10110, and the insulating ring 10110 is bonded to the inner circumference of the fixed cylinder 109, and there is a gap between the limiting ring 1091 and the insulating ring 10110, and an elastic component 101061 is movably connected in the gap, the support ring 10108 is connected to the bottom circumference of the fixed cylinder 109 by threads, and the mounting ring 10101 is connected to the support ring 10108 by threads. The outer circumference, and the fitting groove 10107 is opened between the mounting ring 10101 and the support ring 10108, the fitting groove 10107 is adapted to the receiving ring 1041, the expansion ring 10102 is bonded to the bottom circumference of the support ring 10108, and the external thread ring 10104 is fixedly connected to the bottom circumference of the insulating ring 10110, the external thread ring 10104 and the internal thread ring 1043 are connected by threads, the conductive sheet 10105 is welded to the inner circumference of the external thread ring 10104, and the connecting wire 10106 is plugged into the inner circumference of the conductive sheet 10105, and the sealing ring 10103 is clamped in the fitting groove 10107;

[0042] During installation, first glue the insulating ring 10110 into the fixing tube 109, and let the elastic component 101061 be located above the circumference of the insulating ring 10110. Then, fix the support ring 10108 to the outer circumference of the fixing tube 109 by means of threads. At the same time, connect the mounting ring 10101 to the outer circumference of the support ring 10108 by means of threads, and glue the expansion ring 10102 to the bottom of the support ring 10108. The conductive sheet 10105 is welded to the inner circumference of the external threaded ring 10104, and the top of the external threaded ring 10104 is welded to the bottom of the insulating ring 10110. At this time, pass the connecting wire 10106 through the conductive sheet 10105, and let its end pass through the elastic component 101061. Then, connect the buffer ring 10109 to the top inner circumference of the fixing tube 109 by means of threads, so that a gap is formed between the buffer ring 10109 and the insulating ring 10110, allowing the elastic component 101061 is located in the gap, and then, the storage ring 1041 is inserted into the fitting groove 10107, and the connecting ring 104 is rotated to connect the internal threaded ring 1043 in the storage ring 1041 with the external threaded ring 10104. Thus, through the nested connection structure between the rings, not only the connection stability of the components in the socket 1 is guaranteed, but also there is a certain gap or void between the rings, which plays a role in buffering and absorbing impact force, and reduces the impact of the impact on the structure. At the same time, the impact force is dispersed and transmitted between the rings, so that the impact force is dispersed and mitigated, reducing the impact pressure on the overall structure and improving the impact resistance of the structure.

[0043] The connection between the grooves around the limiting ring 1091 and the connecting wires 10106 prevents the cables from contacting or getting entangled with each other, reduces electromagnetic interference and signal interference, and maintains the stability of the electrical connection.

[0045] When the fixing tube 109 is hit by external force, the connecting wires 10106 in the clamping ring 1010611 located in the gap can adjust the distance between the connecting wires 10106 through the triangular spring piece 1010612, the wavy spring piece 1010613 and the diamond stretching ring 1010614. This not only reduces the vibration and friction between the connecting wires 10106, and protects the connecting wires 10106 from external impact or damage, but also plays a certain buffering role, thereby improving the anti-interference ability of the connecting wire 10106 system.
