Abstract

The utility model relates to a quick inserted self-locking radio frequency coaxial connector. A male connector (3) is symmetrically provided with a through groove (9); a clamping spring (2) is clamped into the through groove (9) along the longitudinal direction of the through groove (9); a convex surface (11) in a sheath (1) is matched with a tilted sheet (10) of an end head of the clamping spring (2). The clamping spring is a U-shaped clamp, and tilted sheets of both end heads are tilted outwards. An inner surface (14) in the sheath is mutually vertical with the convex surface; a rectangular hole (16) of the male connector can be exposed from the center part of the clamping spring. After a female connector (6) is inserted, the clamping spring is clamped with the clamping groove, and the self-locking can be realized. If the female connector needs to be drawn out, the sheath can be pushed to the direction of the male connector and the female connector can be drawn out after the tilted sheets and the clamping spring are expanded by the convex surface. The utility model has the advantage of good connecting performance, and can realize the function of quick inserting and drawing and self-locking. The utility model is suitable for connecting coaxial cables or microstrips in a radio frequency return circuit of microwave equipment and digital communication equipment.

Description

Fast-insertion self-locking RF coaxial connector

Technical field

The utility model relates to a kind of fast-insertion self-locking RF coaxial connector.

Background technology

The SMA series of products are a kind of widely used small-sized coaxial connectors that are threaded, and meet the relevant regulations of MIL-C-39012, IEC169-15 and CECC22110, life-span length, superior performance, reliability height.So be widely used in being connected coaxial cable or little band in the loop of rf of microwave equipment and digital communication equipment.But because SMA series of products interface is to be threaded, can not realize the fast insert-pull function, more can not realize self-locking and increase the reliability of its connection, though directly taking down interface thread, some company can realize fast inserting, but this fast SMA series of products of inserting only are used for experiment test, can't be used for real work.

Summary of the invention

Technical problem to be solved in the utility model is exactly for overcoming the deficiencies in the prior art, but and a kind of fast insert-pull is provided, has auto-lock function and the high fast-insertion self-locking RF coaxial connector of connection reliability.

The technical solution that realizes above-mentioned purpose is:

Symmetry has groove on male connector, and jump ring vertically snaps in the groove along groove, and the convex surface in the sheath cooperates with the oblique sheet of jump ring termination.

Its further technological improvement is:

Jump ring is a U-shaped card, and the oblique sheet of two terminations is all outward-dipping.Inner plane and the orthogonal setting of convex surface in the sheath, inner plane also contacts with the outerplanar of male connector.The rectangular opening of male connector is exposed in the middle part of jump ring.

Be not difficult to find out from above technical scheme,, make this connector can realize the fast-insertion self-locking function fully, and more can improve connection reliability owing to adopted cooperating of jump ring and female connector draw-in groove.Convex surface and the oblique sheet in jump ring termination cooperates and jump ring can be strutted and female connector is extracted rapidly in the sheath.The connector of this structure had both kept SMA series of products superior performance, reliability advantages of higher, have the slotting soon characteristics of SMB, MCX series of products again, also can with QMA series of products exchange of HUBER+SUHNER etc., can be widely used in being connected coaxial cable or little band in the loop of rf of microwave equipment and digital communication equipment.

Embodiment

As shown in Figure 1, have two grooves 9 in its radial symmetric of 15 upper edges that connects of male connector 3, the height of this groove 9 should be greater than the thickness that connects 15, promptly will cut the wall thickness that connects 15 and expose two rectangular openings 16.On the body of male connector 3, also be arranged with two outerplanars 13.In male connector 3, also be provided with contact pin 4 and insulator 5.

As shown in Figure 2, designed outward-dipping oblique sheet 10 respectively on two of a U-shaped jump ring 2 terminations.This jump ring 2 vertically snaps in the groove 9 (referring to Fig. 7, Fig. 8, Fig. 9) along groove 9, and should guarantee on the jump ring 2 that tiltedly the direction of sheet 10 is towards interface 15 upper edges one side.

As shown in Figure 3, sheath 1 is a working of plastics or metalwork, in the inboard symmetric design of sheath 1 two inner planes 14, when the inner plane 14 of sheath 1 and male connector 3 assembling back sheaths 1 promptly with outerplanar 13 applyings (referring to Fig. 5, Fig. 6) of male connector 3.Also design a front with perpendicular sheath 1 inboard of inner plane 14 and be half elliptic convex surface 11 (referring to Figure 10, Figure 11), and the height of opposite one side convex surface is lower than last convex surface 11.The effect of this convex surface 11 is that convex surface 11 props up the oblique sheet 10 of jump ring 2 and jump ring 2 is strutted when promoting sheath 1, and can extract female connector 6 this moment from male connector 3.

As shown in Figure 4, the periphery of the female connector 6 that is made of jack 7, insulator 8 and shell is provided with an annular slot 12 that cooperates with jump ring 2, and the front end of draw-in groove 12 is square ring shape concave station always.

When assembling, earlier jump ring 2 is snapped in the groove 9 of male connector 3, and the direction that makes oblique sheet 10 is towards interface 15 upper edge directions, again the opening part of jump ring 2 is aimed at convex surface 11 in the sheath 1 and male connector 3 and jump ring 2 are together put into sheath 1, and the outerplanar 13 of male connector 3 and the inner plane 14 of sheath 1 are fitted, this moment can be with in the centre bore of female connector 6 insertion male connectors 3 (referring to Fig. 6).The jump ring 2 that exposes rectangular channel 16 after the insertion makes female connector 6 outwards not extract with regard to draw-in groove 12 places that are stuck in female connector 6 and realize self-locking.

When needs were extracted female connector 6, as long as promote sheath 1 to male connector 3 directions, the effect by convex surface 11 outwards strutted oblique sheet 10, and jump ring 2 is outwards strutted, and can extract female connector 6 very like a cork.
