TECHNICAL FIELD

[0001] The application relates to the field of FAKRA wire harness connectors, in particular to a stamping outer conductor structure of an automobile FAKRA wire end connector. BACKGROUND

[0002] With the continuous development of automobile technology, FAKRA wire harness connectors are more and more widely used in automobile electronic equipment. The unique connector and cable design of the FAKRA wire harness connector makes the FAKRA wire harness connector have the characteristics of quick plugging, easy installation and disassembly, and improves the maintenance and replacement efficiency of the wire harness, but the current automobile FAKRA wire end (stamping) outer conductor port adopts a relatively simple guide structure and does not have a piercing structure to increase the holding force when the product is plugged in; most enterprises produce the outer conductor by die casting, and the corresponding product unit price will be higher than that of the stamping product and the weight will also be greater than that of the stamping product, which increases the development cost and does not meet the current trend of reducing the cost and weight of automobiles. CONTENT OF THE UTILITY MODEL

[0017] By adopting the technical scheme, the arrangement of the plurality of riveting points connects the outer guide body with the external structure, the rivet is pressed into the riveting point to deform the outer guide body, and thereby forms a fixation with the external medium body.

[0018] Preferably, the outer surface of the outer guide body is protrudingly arranged as a limiting protrusion around one end close to the movable groove.

[0019] By adopting the technical scheme, the limiting protrusion protrudes around the outer guide body, thereby reserving space for the bending of the movable groove channel and increasing the movement range of the spring piece body.

[0020] Preferably, a plurality of convexes are arranged on the inner surface of the outer guide body at the position of the limiting protrusion.
