[0029] Embodiment:

[0030] As Figures 1-4 shown, a rectangular connector tail accessory includes a shell 1, a wire pressing plate 2 and an elastic member 3; the shell 1 is provided with a through threading hole 101 and a pressing groove 102 adapted to the wire pressing plate 2, the threading hole 101 is in communication with the pressing groove 102; the wire pressing plate 2 is detachably arranged on the pressing groove 102, when the wire pressing plate 2 is connected with the shell 1, the wire pressing plate 2 and the threading hole 101 enclose an annular pressing area 4, the elastic member 3 is inserted into the annular pressing area 4 and used for fixing the wire.

[0031] The rectangular connector tail accessory is characterized in that the wire passes through the wire hole 101 and is connected with the connector, the gap between the wire and the annular compression area 4 is filled by the elastic member 3, the wire is fastened by the pressure applied by the wire pressing plate 2, and thus the wire is effectively fixed, the displacement of the wire relative to the connector is reduced, the reliability and stability of the connection between the connector and the wire are ensured, and the signal transmission is more stable and reliable.

[0032] In operation, the shell 1 is fixedly connected with the connector, one end of the wire is connected with the connector, and the other end of the wire passes through the wire hole 101. An appropriate elastic member 3 is selected and placed on the annular compression area 4, the wire at least partially contacts the elastic member 3, and finally the wire pressing plate 2 is fixed on the shell 1.

[0033] Therefore, the rectangular connector tail accessory has the advantages of simple structure, fast and convenient assembly, and low cost. Meanwhile, the elastic member 3 is deformed under pressure and covers the wire, which ensures the fixing effect and reduces the damage to the wire, thereby helping to prolong the service life of the wire.

[0034] Further, since the wire is fixed by being pressed, when disturbance occurs under the interference of external factors, although the elastic member 3 can play a certain buffering protection role, the wire is still prone to deformation, fracture and other problems at the fixed position. In order to avoid the above problems, the rectangular connector tail accessory is preferably arranged in an area with less disturbance, or a certain amount of slack is left on both sides of the wire at the fixed position, and the displacement of the slack part is used to cope with external interference.

[0035] In a possible implementation, the wire hole 101 is located at part of the annular compression area 4 to form a first groove body, and a second groove body is arranged on the wire pressing plate 2. Correspondingly, when the wire pressing plate 2 is connected with the shell 1, the first groove body and the second groove body are communicated to form the annular compression area 4. Based on the above design scheme, the volume of the annular compression area 4 is increased by the design of the second groove body, which can be used for wires of different diameters and quantities on the one hand to expand the use range, and on the other hand also facilitates the installation of the elastic member 3 and is more convenient to use.

[0036] It is easy to understand that the first groove body and the second groove body can be constructed in any suitable shape, and the first groove body can be located at any suitable position on the shell 1, preferably, as shown in Figure 3 the first groove body is located at the end of the shell 1, which facilitates the disassembly and assembly of the wire pressing plate 2.

[0037] As to the structure of the wire pressing plate 2, in a possible implementation, the wire pressing plate 2 is in the shape of a straight plate and is provided with an inner groove, the two sides of the inner groove are respectively provided with a first connecting hole penetrating through, the inner groove is constructed as the second groove body, and the first connecting hole is used to connect the shell 1 and is detachably provided with a first connecting rod.

[0038] In another possible implementation, the wire pressing plate 2 comprises a first plate body and a second plate body, the first plate body is connected with the end of the second plate body and forms an L-shaped plate, the first plate body is provided with a second connecting hole for connecting the shell 1, and the second connecting hole is detachably provided with a second connecting rod correspondingly, and the second plate body is provided with the second groove body.

[0039] Based on the above design scheme, the cable can be divided into different specifications according to the diameter, and correspondingly, the connector can also be large or small. For the connector with large size, the size of the shell 1 and the wire pressing plate 2 is also large, and on the basis of ensuring the structural strength and convenient disassembly, the wire pressing plate 2 can be made into any suitable shape, and considering the production and manufacturing factors, the wire pressing plate 2 is preferably in a straight plate shape. Conversely, if the size of the shell 1 is small, in order to ensure the structural strength and convenient disassembly, the wire pressing plate 2 is preferably constructed as an L-shaped plate to relatively expand the volume of the wire pressing plate 2, and also reserve sufficient space for the second connecting hole, the second groove body and other structures.

[0040] It is easy to understand that the first connecting rod and the second connecting rod can be selected as any suitable shaft fastener, preferably, the first connecting hole and the second connecting hole are constructed as screw holes, and correspondingly, the first connecting rod and the second connecting rod are selected as suitable bolts or screws, which are stable in connection and can be detachably connected.

[0041] For the elastic member 3, in one possible implementation, the elastic member 3 is constructed as a ring structure, the outer circumferential surface of the ring structure is adapted to the annular pressing area 4, and the inner circumferential surface of the ring structure forms the auxiliary wire hole;

[0042] In another possible implementation, the elastic member 3 is constructed as a block structure, the block structure has two opposite outer surfaces, one of which is constructed as an abutting surface for abutting the first groove body or the second groove body, and the other is constructed as a connecting surface for contacting the wire.

[0043] Based on the above design scheme, the elastic member 3 is made of any suitable elastic material, and the wire is protected by the elastic member 3, therefore, the elastic member 3 is preferably constructed as a ring structure to realize 360° omnidirectional coverage of the wire. Conversely, the elastic member 3 is constructed as a block structure, and the contact area between the elastic member 3 and the wire is increased by the pressing of the wire pressing plate 2, but part of the wire abuts against the shell 1 or the wire pressing plate 2, but the amount of the elastic member 3 is reduced, which helps to reduce the cost.

[0044] It is easy to understand that according to the actual installation requirements, the person skilled in the art can select the elastic member 3 of the ring structure or the elastic member 3 of the block structure as needed.
