[0003] Most existing port connection devices are not designed with protection mechanisms. In the process of connecting devices through wires, the wires are easily affected by the external environment. For example, due to accidental contact, the connector at the end of the wire may become loose or even fall off at the device port, affecting the connection stability of the device. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A connection device for a port comprises a device frame 1, a shift rod 2 is movably provided on the inner side of the device frame 1, one end of the shift rod 2 is fixedly connected to a damping shaft 3, one end of the damping shaft 3 away from the shift rod 2 is fixedly connected to a connecting plate 4, a shape memory hoop 5 is provided at the bottom of the connecting plate 4, a sleeve mechanism is provided on the shape memory hoop 5, and a buffer protection mechanism for improving the stability of the port connection is provided on the device frame 1.

[0021] Through the above technical solution, when the device is in use, the wire connected to the connector at the port passes through the shape memory hoop 5, and the wire is stably clamped under the action of the hoop mechanism. At this time, there is a certain pulling space between the wire clamping position and the port connection (that is, the wire here is in a relaxed and bent state), which can effectively improve the wire's anti-pulling ability, and the buffer protection mechanism can reduce the impact of external impact force.

[0022] Specifically, the hoop mechanism includes a tooth sleeve 6 fixedly connected to one end of the shape memory hoop sheet 5 , and a tooth plate 7 is provided at one end of the shape memory hoop sheet 5 away from the tooth sleeve 6 , and the outer surface of the tooth plate 7 is meshedly connected with the inner surface of the tooth sleeve 6 .

[0023] Through the above technical solution, as the tooth plate 7 gradually goes deeper into the tooth sleeve 6, the shape memory hoop 5 will be gradually tightened until it tightly clamps the wire.

[0024] Specifically, the buffer protection mechanism includes a short spring 8 movably sleeved on the outer surface of the shift rod 2, one end of the shift rod 2 away from the damping shaft 3 is fixedly connected to a first recess 9, and the inner side of the first recess 9 is rotatably connected to a cross rod 10.

[0025] Through the above technical solution, the damping shaft 3 will drive the shift rod 2 and the first recessed frame 9 to rotate synchronously during the rotation process, and will maintain a relatively stable state after rotating to the corresponding position.

[0026] Specifically, the inner side of the device frame 1 is fixedly connected with a base 11 , the outer surface of the base 11 is fixedly connected with a buffer tube 12 , and the outer surface of the buffer tube 12 is movably sleeved with a long spring 13 .

[0027] Through the above technical solution, the long spring 13 buffers the force from the second recessed frame 17 at the outer periphery of the buffer tube 12 .

[0028] Specifically, a foam pad 14 is disposed inside the buffer tube 12 , a buffer plate 15 is slidably connected to the inner surface of the buffer tube 12 , and a buffer rod 16 is fixedly connected to the outer surface of the buffer plate 15 .

[0029] Through the above technical solution, the foam pad 14 has good buffering deformation ability and can buffer and relieve the compression of the buffer plate 15.

[0030] Specifically, one end of the buffer rod 16 away from the buffer plate 15 is rotatably connected to the second recessed frame 17 , and the inner surface of the second recessed frame 17 is rotatably connected to the outer surface of the cross rod 10 .

[0031] Through the above technical solution, the first recessed frame 9 can be rotated in conjunction with the second recessed frame 17 through the cross rod 10 during the rotation process, so as to cooperate with adjusting the shape memory hoop sheet 5 to a corresponding position.

[0032] Working principle: When the port connection device is in use, the wire connected to the plug at the port is passed through the inner side of the shape memory hoop 5, and the tooth plate 7 is inserted into the tooth sleeve 6. During this process, as the tooth plate 7 goes deeper, the shape memory hoop 5 will gradually shrink until the wire is tightly clamped. The wire here has a certain pulling space from the plug of the port. When the wire is pulled by the outside world, the shift rod 2 will move laterally and compress the short spring 8 to generate a reverse buffering force. At the same time, the force is transmitted to the second recess 17 through the first recess 9 and the cross rod 10, and the buffer rod 16 is allowed to go deep into the buffer tube 12. The buffer plate 15 squeezes the foam pad 14, and cooperates with the compression deformation of the long spring 13 to effectively buffer and release the impact force and reduce the pulling force. The impact of instantaneous impact force on the plug at the end of the wire, and when the end is in different positions, the position of the shape memory hoop 5 can be adjusted to move it to a position that is convenient for clamping the wire, that is, rotating the damping shaft 3 drives the connecting plate 4 to move synchronously, and then links the shape memory hoop 5 to adjust the position. During this process, the shift rod 2 will drive the first recess 9 to flip, and at the same time drive the second recess 17 to deflect to the corresponding position. The shape memory hoop 5 after the position is adjusted can be buffered and protected by the buffer protection mechanism, and the tensile strength of the wire after the position adjustment is also improved. During the entire process of connecting the wires at the end, through the contraction of the shape memory hoop 5, the device can ensure that the connection between the wire and the port plug is tight and firm, reducing the risk of accidental disconnection.
