Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to a terminal sheath component. Background Art

[0002] With the continuous development of electrical connection technology, the in-mold assembly process of sleeve female terminals has gradually become a trend due to its advantages such as high efficiency and stability. According to the assembly process, the terminal body is inserted into the sleeve, and then a part of the barrel wall near the positioning hole on the sleeve is riveted into the positioning groove of the terminal body to achieve the fixation between the sleeve and the terminal body.

[0003] In practice, during the assembly process, the sleeve may rotate around the axial direction relative to the terminal body. That is to say, during the assembly process, a relative displacement will occur between the sleeve and the terminal body in the circumferential direction, resulting in a positional misalignment between the locating hole on the sleeve and the locating groove on the terminal body, thereby causing damage to the terminal body and the sleeve in the subsequent riveting operation, affecting subsequent processing and appearance.

[0031] Specifically, according to an exemplary embodiment of the present utility model, Figures 1 to 5As shown, one of the first anti-rotation structure and the second anti-rotation structure is at least one guide groove 110 extending along the axial direction X, and the other of the first anti-rotation structure and the second anti-rotation structure is at least one protrusion 210, wherein, during the process of the sleeve 200 being assembled to the main body 101 of the terminal 100, the at least one protrusion 210 travels along the at least one guide groove 110 to prevent the sleeve 200 from rotating around the main body 101. Figures 1 to 5 In the exemplary embodiment shown, the first anti-rotation structure is at least one guide groove 110 extending along the axial direction X, and the second anti-rotation structure is at least one protrusion 210; wherein the guide groove 110 is provided on the outer surface of the main body portion 101 of the terminal 100, and the protrusion 210 protrudes radially inward from the inner surface of the sleeve 200.
