Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector and an electrical element. Background Art

[0002] The connector includes a male end and a female end, through which signals or currents can be transmitted to connect two active devices.

[0003] Most connectors are rectangular in structure and use mechanical error-proofing for mating, which requires manual mating operations in a visual environment. For cylindrical connectors used in situations where space is limited (such as inside a shock absorber), the male and female ends need to be blind-mated. Existing cylindrical connectors are difficult to align during blind mating and may be mis-mated. Utility Model Content

[0004] The embodiments of the utility model provide a connector and an electrical component, which can improve the technical problems of the existing connectors that are difficult to align and may be inserted incorrectly during blind insertion.

[0005] In a first aspect, an embodiment of the present utility model provides a connector, comprising:

[0006] The male end includes a cylindrical first plug-in portion, and a first guide boss is disposed inside the first plug-in portion;

[0007] The female end includes a cylindrical second plug-in portion, and a guide groove is arranged on the outer peripheral surface of the second plug-in portion. The guide groove includes a V-shaped groove section and an I-shaped groove section which are connected to each other. The groove width of the V-shaped groove section gradually decreases along the direction approaching the I-shaped groove section. The I-shaped groove section extends along the axial direction of the second plug-in portion. A second guide boss is arranged in the V-shaped groove section. The height of the second guide boss is less than or equal to the distance between the inner surface of the first plug-in portion and the groove bottom of the V-shaped groove section. The first guide boss is configured to slide from the V-shaped groove section into the I-shaped groove section when the female end and the male end are plugged in.

[0008] In the embodiments of the utility model, the V-groove is provided to help improve the problem of inconvenient alignment when the male / female ends are plugged in, and the second guide boss is provided in the V-groove segment so that the cross-sectional profile of the portion of the female end with the V-groove segment can be made approximately circular, thereby avoiding the problem of incorrect plugging caused by the groove bottoms of the V-groove segments of the male and female ends fitting together and the first guide boss being inserted into the opposite side of the V-groove segment of the female end due to the large inclination angle when the male end and the female end are plugged in.

[0009] In one embodiment, the height of the second guide boss is equal to the depth of the V-shaped groove segment.

[0010] In an embodiment of the utility model, by making the height of the second guide boss equal to the depth of the V-shaped groove section, the cross-sectional profile of the portion of the female end provided with the V-shaped groove section can be made more approximately circular, thereby better avoiding the problem of incorrect insertion between the male end and the female end during blind insertion.

[0011] In one embodiment, both side walls of the V-shaped groove section are arc-shaped walls, and are smoothly transitioned to the two side walls of the I-shaped groove section respectively; and / or

By making the two side walls of the V-shaped groove section symmetrically arranged relative to the extension direction of the I-shaped groove section, and making the two side walls of the V-shaped groove section intersect at the ends away from the I-shaped groove section, the opening of the side of the V-shaped groove section close to the male end can be made larger, so that the first guide boss can enter the V-shaped groove section more easily, and then the blind plugging of the male end and the female end is easier.

[0014] In one embodiment, one end of the second guide boss intersecting with the two side walls of the V-shaped groove section is disposed opposite to each other on the second plug-in portion.

[0015] In an embodiment of the utility model, by arranging the second guide boss and the end where the two side walls of the V-shaped groove segment intersect on the second plug-in portion back to back, the second guide boss effectively fills the cavity formed by the V-shaped groove segment, so that the cross-sectional profile of the portion of the female end with the V-shaped groove segment can be better made to be closer to a circle, thereby better avoiding the problem of incorrect plugging between the male end and the female end during blind plugging.

[0018] In one embodiment, the cross-section of the first guide boss is elliptical, the extension direction of the long axis of the first guide boss is the same as the extension direction of the I-shaped groove segment, and the length of the short axis of the first guide boss is smaller than the width of the first guide groove, the second guide groove and the I-shaped groove segment.

[0019] In the embodiment of the utility model, by making the cross section of the first guide boss elliptical, the first guide boss can slide in the guide groove without plane contact, thereby improving the smoothness of the male end and the female end when plugging, and reducing the sense of resistance. By making the extension direction of the long axis of the first guide boss the same as the extension direction of the I-shaped groove section, and the length of the short axis of the first guide boss smaller than the width of the first guide groove, the second guide groove and the I-shaped groove section, the first guide boss can slide more easily in the guide groove and not easily slide out.

[0020] In one embodiment, the shape of the circumference of the second guide boss on one side close to the I-shaped groove segment is a first V-shape, the first V-shape has a sharp point, the extension directions of the two side edges of the first V-shape are respectively the same as the extension directions of the two side walls of the V-shaped groove segment, and the sharp point faces the I-shaped groove segment, and the sharp point is arranged on one side of the central axis of the V-shaped groove segment; and / or

[0021] The shape of the circumference of the second guide boss on the side away from the I-shaped groove section is a second V-shape.

By making the peripheral surface of the second guide boss away from the I-shaped groove section into a second V-shape, a better guiding function can be achieved when the first guide boss slides into the V-shaped groove section.

[0023] In one embodiment, the peripheral surface of the second guide boss is an arc-shaped surface.

[0024] In the embodiment of the utility model, by making the peripheral surface of the second guide boss an arc-shaped surface, the first guide boss can slide in the guide groove without plane contact, thereby improving the smoothness of the male end and the female end when plugging together and reducing the sense of obstruction.
