Example 1

As shown in fig. 1-3 and fig. 7-8, the invention provides a light modular connector, which includes a hollow middle outer conductor 1, a plastic first outer conductor 2 is sleeved on a rear section of the middle outer conductor 1, an elastic contact sleeve 3 is inserted into a front section of the middle outer conductor 1, preferably, the contact sleeve 3 is in a straight cylinder shape, a convex cambered surface structure 33a is integrally formed on the front section of the contact sleeve 3, and a plurality of open grooves 32 extending from the rear end to the front end are circumferentially and uniformly distributed on the contact sleeve 3; the rear end of the contact sleeve 3 is integrally stretched or stamped with an outer bending structure 31, wherein the outer bending structure 31 comprises a joint surface 31a and an extrusion surface 31b, a step 11 which is combined with the outer bending structure 31 in an extrusion manner is arranged around the middle section of the middle outer conductor 1, and preferably, the step 11 protrudes a bendable pressing ring part 11a towards the contact sleeve 3; the insulating support 4 is arranged behind the outer bending structure 31 inside the step 11, and a protrusion 41 abutting against the inner wall of the contact sleeve 3 is arranged on the insulating support 4, preferably, the protrusion 41 does not exceed the end face of the contact sleeve 3 far away from the insulating support 4.

Compared with the traditional connector, the connector adopts the plastic material to replace the pure copper material to manufacture the first outer conductor 2 so as to achieve the effects of reducing weight and saving cost, and can effectively combine the plastic first outer conductor 2 with the pure copper middle outer conductor 1 by adopting a secondary injection molding mode.

In this embodiment, the contact sleeve 3 is manufactured by an integral stretching process or a punching and rolling process, the opening groove 32 provides the contact sleeve with strong elasticity, and the convex arc-shaped structure 33a can be better electrically connected with other connectors. When the contact sleeve 3 is installed, the extrusion surface 31b of the contact sleeve 3 can be fixed by the bent press ring part 11a through the outer bending structure 31 designed at the rear end of the contact sleeve 3 (the specific method is that a special taper angle tool is used for extruding the press ring part 11a to enable the press ring part to be bent and deformed, and then the circumference of the extrusion surface 31b is covered and fixed), or other extrusion structural members (not shown in the figure) are directly pressed and fixed, so that the combination surface 31a and the step 11 are combined into a whole, and the fixing effect of the contact sleeve 3 is ensured.

Considering that the thin-walled contact sleeve 3 may deform and contract to affect normal use, the insulating support 4 is further provided with a protrusion 41, and the protrusion 41 can support the contact sleeve 3 to prevent the contact sleeve 3 from deforming and contracting.
