Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector connection structure technology, and in particular to an outer conductor assembly of a connector. Background Technology
[0002] Currently, automotive connectors function as bridges between blocked or isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Automotive connectors come in a wide variety of forms and structures, primarily consisting of contacts, a housing (depending on the type), an insulator, and accessories. The contacts are the core components of an automotive connector, responsible for achieving the electrical connection. They typically consist of male and female contacts forming a contact pair, with the electrical connection achieved through the mating of these contacts. A typical automotive vehicle uses nearly a hundred different types of connectors, with a single model employing hundreds. As people demand higher levels of safety, environmental friendliness, comfort, and intelligence in automobiles, the application of automotive electronic products is increasing, leading to a surge in the number of automotive connectors used. However, some connectors rotate during the connection process, requiring post-assembly fixing or other secondary fixing processes, which can affect the reliability of the connection.
[0003] To address these issues, we developed an outer conductor assembly for the connector. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing an outer conductor assembly for a connector, which has advantages such as axial anti-retraction, radial anti-rotation, and improved connection reliability.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an outer conductor assembly of a connector, comprising an outer conductor, a dielectric body, and an inner conductor. A socket is provided at the center of the dielectric body, and the inner conductor is inserted into the socket. The inner wall of the outer conductor is inserted into the dielectric body. At least one baffle is provided on the inner wall of the outer conductor, and the baffle is inserted into the bottom end of the dielectric body. A circumferentially distributed protrusion is provided on the bottom outer wall of the dielectric body, and a second notch is provided between two adjacent protrusions. The second notch engages with the baffle.
[0006] Preferably, the outer conductor has a plurality of first notches at the bottom outer wall, and a hook is provided at each of the first notches.
[0007] Preferably, the outer wall of the medium is provided with a through hole, and the through hole is engaged with the hook.
[0008] Preferably, the hook has a first plane and the through hole has a second plane, with the first plane abutting against the second plane.
[0009] Preferably, the bottom outer wall of the medium is provided with circumferentially distributed protrusions, and a second notch is provided between two adjacent protrusions, the second notch engaging with the wall.
[0010] Preferably, the outer wall of the protrusion is provided with parallel protrusions.
[0011] Preferably, the outer conductor has a third notch evenly distributed around its circumference at the top outer wall, a snap-fit piece is provided at the third notch, the snap-fit piece has a bend at its top end, the snap-fit piece is inserted into the dielectric body, and the dielectric body has a protrusion at its top end, the bend is inserted into the protrusion.
[0012] Preferably, the angle between the inner wall of the snap-fit tab and the outer wall of the outer conductor is α, and the angle α is an acute angle.
[0013] Preferably, an arc ring is provided at the middle position of the outer wall of the outer conductor.
[0014] Preferably, the lower side of the arc ring is provided with a protrusion, which is arranged in the circumferential direction of the outer conductor.
[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0016] The outer conductor assembly of the connector of this utility model has an inner snap hook with a piercing structure, and a groove is left at the corresponding height position of the dielectric body. After the two are assembled, the hook abuts in the groove to prevent it from falling back. At the same time, the bottom protrusion of the dielectric body abuts against the outer conductor, so that the two are completely limited in the axial direction. Meanwhile, the staggered design of the tails of the two can play a role in preventing rotation and limiting in the vertical direction of the axial direction, which also improves the reliability of the electrical connection.
