The end of the PLR structure 30 away from the mating connector extends outward to form a first clamping arm 302, the first clamping arm 302 clamps with the inner wall of the sheath body 10 to achieve positioning of the PLR structure 30 in the pre-assembly position; the PLR structure 30 is also formed with an arched structure 303 arched outward, the inner side of the arched structure 303 has a free end of a second clamping arm 304 facing the mating connector, the second clamping arm 304 clamps with the outer wall of the terminal mounting portion 20 to achieve positioning of the PLR structure 30 in the locking position; the first clamping arm 302 and the second clamping arm 304 are independently arranged, so that the PLR structure 30 has good stability when installed in the connector. The outer wall of the second clamping arm 304 and the inner wall of the arched structure 303 have a clearance 305, by pulling the free end of the second clamping arm 304, the free end of the second clamping arm 304 can be offset in the direction of the arched structure 303, to achieve unlocking of the PLR structure 30 in the locking position, so that the PLR structure 30 is easy to disassemble from the connector; in summary, the connector with the PLR structure 30 has the advantages of stability and easy disassembly.

[0035] As shown in Figure 4 and Figure 5As shown, the PLR structure 30 includes a frame-shaped main body 301, and a first clamping arm 302 is arranged on one set of opposite side walls of the main body 301, which are arranged in a manner opposite to each other, so that when the frame-shaped main body 301 is mounted to the connector, it has good stability and can prevent the PLR structure 30 from falling off the terminal mounting portion 20.

[0040] Further, as shown in Figure 4 and Figure 5 , in order to facilitate the assembly and structural stability of the PLR structure 30, the first clamping arm 302 and the positioning arm 308 are flushly arranged at the end away from the mating connector.

[0041] In an embodiment, as shown in Figures 1-5 , an embedded groove 203 with a width larger than the second clamping groove 202 is formed at the entrance of the second clamping groove 202, and an embedded block 311 matching the embedded groove 203 is protrusively arranged at the free end of the second clamping arm 304, the embedded block 311 is embedded in the embedded groove 203 when the PLR structure 30 is in the locked position, and details are shown in Figure 7 , the embedded groove 203 assists in positioning the locked position of the PLR structure 30, prevents it from shaking left and right, and improves the structural stability of the PLR structure 30 and the connector.

[0042] In an embodiment, as shown in Figure 1As shown, the sheath body 10 has an operation window 102 facing one end of the mating connector, which partially exposes the PLR structure 30, so as to facilitate disassembly of the PLR structure 30. Specifically, when disassembling the PLR structure 30, the operator can displace the free end of the second clamping arm 304 towards the direction of the arcuate structure 303 by pulling the free end of the second clamping arm 304, so as to unlock the PLR structure 30 in the locked position. At the same time, the operator applies an outward force at the operation window 102, so as to make the PLR structure 30 retreat from the locked position to the pre-assembly position. Then, the operator continues to apply an outward force to the PLR structure 30, so as to separate the PLR structure 30 from the terminal mounting portion 20, thereby achieving convenient disassembly of the PLR structure 30.
