Description

FAKRA automobile connector

Technical Field

The utility model relates to a connector technical field, especially a FAKRA automobile connector.

Background

The conventional FAKRA automobile connector generally comprises a plastic main body, an alloy shell and a terminal assembly, wherein the terminal assembly is assembled in the plastic main body after being assembled in the alloy shell, and the alloy shell is inserted into a jack of the plastic main body and is fixed; the fixed structure that adopts independent shell fragment card to go into the five metals draw-in groove or adopt plastic and five metals to interfere firmly between alloy housing and the plastic main part is heated or external force makes bullet wall warp or arm of force under the circumstances such as unsaturated mould match and is drawn and drop easily to the independent plastic bullet wall of product of this kind requires very high to the plastic mould: the angle, the height, the thickness of the spring wall and the like need to be controlled, and the manufacturing cost is higher.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, provide a FAKRA automobile connector.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a FAKRA automobile connector comprises a plastic main body, an alloy shell and a terminal assembly, wherein the terminal assembly is assembled in the plastic main body after being assembled in the alloy shell, and the alloy shell is inserted into a jack of the plastic main body and is fixed; a plurality of buckles which are distributed at equal intervals are integrally formed on the outer wall of the insertion part of the alloy shell, corresponding clamping grooves are distributed at equal intervals on the inner side of the insertion hole, and the buckles are buckled in the clamping grooves; the plastic main part integrated into one piece has outer wall and coaxial inner wall apart from each other, and the inner wall links up through the bottom with the outer wall, is provided with continuous concave-convex tooth at the top of inner wall, concave-convex tooth is as the draw-in groove.

In the above technical scheme, a reinforcing rib is arranged between the outer wall and the inner wall.

In the above technical solution, the reinforcing ribs are connected to the convex teeth.

In the technical scheme, the inner side of the jack is provided with the concave sliding groove extending along the axis direction, and when the insertion part enters the jack, the buckle slides in along the concave sliding groove and is finally buckled in the clamping groove.

The utility model has the advantages that:

1) the alloy shell and the plastic main body are fixed by combining the modes of integration, sliding grooves, hard interference and hanging platforms.

2) The inner wall as the vertical annular elastic wall has very large force which can be borne in the vertical direction, and has larger pull-out resistance force and stronger weather resistance and is more reliable than a single elastic sheet type structure.

3) The conventional elastic deformation of the inner wall of the integral plastic main body can meet the product requirement, the processing difficulty and precision of the plastic mold are reduced, and the integral production efficiency is effectively improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 to 4, a FAKRA automotive connector includes a plastic body 1, an alloy housing 2 and a terminal assembly, wherein the terminal assembly is assembled into the plastic body 1 after being assembled into the alloy housing 2, and the alloy housing 2 is inserted into a jack 4 of the plastic body 1 and fixed; a plurality of buckles 6 distributed at equal intervals are integrally formed on the outer wall 8 of the insertion part 5 of the alloy shell 2, corresponding clamping grooves are distributed at equal intervals on the inner side of the insertion hole 4, the buckles 6 are buckled in the clamping grooves, and the root of the insertion part 5 is in a circular truncated cone shape and is attached to the opening edge chamfer of the insertion hole 4; plastic main part 1 integrated into one piece has outer wall 8 and coaxial inner wall 9 apart from, and inner wall 9 links up through the bottom with outer wall 8, is provided with continuous concave-convex tooth at the top of inner wall 9, concave-convex tooth 10 is as the draw-in groove. The insertion surface of the buckle 6 is an inclined guide surface, which is beneficial to insertion.

As shown in fig. 3, a rib 12 is provided between the outer wall 8 and the inner wall 9. The ribs 12 are connected to the teeth 11 to enhance the reliability of the teeth 11.

As shown in fig. 2, a concave sliding groove 13 extending along the axial direction is arranged inside the insertion hole 4, and when the insertion portion 5 enters the insertion hole 4, the buckle 6 slides in along the concave sliding groove 13 and is finally buckled in the clamping groove, so that the insertion smoothness is improved.

As shown in fig. 2, the terminal assembly includes a terminal enclosure 14 and a terminal 7. The elongated terminal is partially inserted into the terminal cover 14 and partially exposed. A resin film 3 is also attached to the back surface of the alloy case 2.

The utility model discloses a theory of operation: insert portion 5 of alloy housing 2 when inserting jack 4 of plastic main part 1, aim at buckle 6 and concave spout 13, the application of force makes alloy housing 2 insert into, insert portion 5 in-process, buckle 6 can be through the mode of hard interference with inner wall 9 extrusion deformation, because inner wall 9 is the plastic material, itself has certain bullet shape deformation nature, after targetting in place, buckle 6 detains in the draw-in groove, the root of insert portion 5 is the opening edge chamfer of round platform form and jack 4 and laminates mutually.
