Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a FAKRA connector and connector assembly. Background Technology

[0002] Automotive connectors are signal hubs connecting the electronic systems within a vehicle. With the rapid development of automotive electrification and intelligence, higher demands are placed on the miniaturization and waterproofing of connectors. There is an urgent need to upgrade and replace traditional connectors through innovative structures, cost reduction, and ease of operation to adapt to market trends. Currently, FAKRA connectors, in order to reduce costs, mostly use a stretching structure for the outer conductor portion of the wire end. Among the stretching structures, the most common is the petal spring structure. However, due to its segmented structure, its performance is slightly insufficient in some extreme tests such as oblique insertion and vibration. This problem arises because when the petal spring body is inserted, if it is obliquely inserted or subjected to strong force, the petal will be subjected to force on one side, causing deformation of the spring, which in turn leads to insufficient holding force of the stretching body or deformation of the spring. Utility Model Content

[0003] Based on the above-mentioned technical problems, this application provides a FAKRA connector and connector assembly, which can strengthen the retaining force of the connector and avoid the problem of spring deformation.

[0006] Furthermore, the arm guard collar includes an integrally connected retaining part and a locking part, with the front end of the arm guard collar recessed inward to form the locking part.

[0007] Furthermore, the elastic contact member includes a cylindrical sleeve portion and a spring arm portion, with the engaging portion of the guard arm collar fitted onto the outside of the spring arm portion.

[0008] Furthermore, the outer conductor is a straight outer conductor, the elastic contact includes a first elastic contact, the insulating core includes a first insulating core, the terminal includes a first terminal, the straight outer conductor is sleeved outside the rear end of the first elastic contact, the first insulating core is inserted into the front end of the first elastic contact, and the first terminal is located at the center of the first insulating core.

[0011] Furthermore, it also includes a locking component, wherein the insulating housing is provided with an insertion part, the outer conductor is provided with a slot, and the locking component is detachably installed in the insertion part and snapped into the slot.

[0012] This application also provides a connector assembly, including a FAKRA connector as described above and a mating connector connected thereto. The mating connector includes a plastic housing, and a center terminal, a terminal housing, and a shielding housing sequentially disposed in the cavity of the plastic housing from the inside to the outside. When the FAKRA connector is inserted into the mating connector, the shielding housing on the mating connector is inserted into the elastic contact on the FAKRA connector, and the shielding housing contacts the spring arm portion on the elastic contact.
