Abstract

The utility model discloses a jack connector, which comprises a contact (1), an insert (2), an insulator (3), a shell (4), a spring (5), a pressing sleeve (6), a connecting sleeve (7) and gaskets (8, 9). The insert (2) is tightly installed in the insulator (3), which is tightly installed in the shell (4); the contact (1) is tightly installed between the shell (4) and the insulator (3); the connecting sleeve (7) is sleeved on one end of the shell (4); and the spring (5), both ends of which are respectively provided with the gaskets (8, 9), is nested on the contact (1). The peripheral middle part of the contact (1) is provided with a step (12), and the large end of the contact (1) is provided with an elastic hollow body. A circle of outer convex rib (14) protrudes outwards along a radial direction on the port of the big end of the contact (1), and a circle of inner lug boss (13) protrudes inwards along the radial direction on the port of the big end of the contact (1). A circle of inner lug boss (71), which is against the outer convex rib (14) of the contact (1), protrudes inwards on the port connected with the connecting sleeve (7). The utility model changes the threaded connection of the prior jack connector into direct plugging type sliding connection, so connection is convenient, and performance is stable.

Description

Receptacle connector

Technical field

The utility model relates to a kind of telecommunication apparatus and radio instrument radio frequency (RF) coaxial connector, relates in particular to a kind of socket connector.

Background technology

At present, the interconnection of radio-frequency (RF) coaxial receptacle connector commonly used all adopts screw-type to connect, and when being subjected to the excess load vibration or stretching, connector is very easily loosening to cause signal interruption, directly influences the normal performance of its function.

Summary of the invention

The purpose of this utility model is the mechanical strength deficiency that exists at existing receptacle connector, easily loosening and cause the problem of signal interruption, and it is good to propose a kind of mechanical strength, radio-frequency (RF) coaxial receptacle connector easy for installation.

The technical solution of the utility model is:

A kind of receptacle connector, comprise contact head 1, plug-in unit 2, insulator 3, shell 4, spring 5, gland 6, adapter sleeve 7, packing ring 8,9, described plug-in unit 2 is fitted in the insulator 3, and described insulator 3 is fitted in the shell 4, and one end 31 is resisted against on the first counterbore bottom surface 41 of described shell 4; Contact head 1 is fitted between shell 4 and the insulator 3, and one end 11 is resisted against on the second counterbore bottom surface 42 of described shell 4; Described adapter sleeve 7 is sleeved on an end of shell 4, and described spring 5 is sleeved on the contact head 1, and its two ends are provided with packing ring 8, packing ring 9 respectively; Described gland 6 is placed on the crimp tail of shell 4; Described contact head 1 is for the middle part of periphery is provided with step 12, and is provided with the hollow body of elastic construction at big end.The outstanding circle outer convex rib 14 of the radial outward of this contact head 1 big end port, an inwardly outstanding circle inner convex platform 13.

The elastic construction of described contact head 1 is the big end end face at contact head 1, uniform vertically at least 4 elongated slots.

The inwardly outstanding circle inner convex platform 71 of the port of described adapter sleeve 7, this inner convex platform 71 props up the outer convex rib 14 of described contact head 1, the inwardly outstanding circle inner convex platform 72 in the middle part of described adapter sleeve 7, described packing ring 8 is resisted against on described inner convex platform 72 and the described contact head step 12.

The utlity model has following advantage:

The utility model offsets by the outer convex rib 14 of contact head 1 and the inner convex platform 71 of adapter sleeve 7, can tightly block connected coaxial cable.By the effect of spring 5, adapter sleeve 7 is moved axially, unclamp connected coaxial cable, the utility model connects conveniently, guarantees that the equipment performance that is connected is stable.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, receptacle connector of the present utility model, it comprises contact head 1, plug-in unit 2, insulator 3, shell 4, spring 5, gland 6, adapter sleeve 7, packing ring 8,9.Plug-in unit 2 is fitted in the insulator 3, and insulator 3 is fitted in the shell 4, and one end 31 is resisted against on the first counterbore bottom surface 41 of described shell 4; Contact head 1 is fitted between shell 4 and the insulator 3, and one end 11 is resisted against on the second counterbore bottom surface 42 of described shell 4; Adapter sleeve 7 is sleeved on an end of shell 4, and spring 5 is sleeved on the contact head 1, and its two ends are provided with packing ring 8, packing ring 9 respectively; Gland 6 is placed on the crimp tail of shell 4; Contact head 1 is for the middle part of periphery is provided with step 12, and is provided with the hollow body of elastic construction at big end.The radially outwards outstanding circle outer convex rib 14 of the big end port of this contact head 1, an inwardly outstanding circle inner convex platform 13.The elastic construction of contact head 1 is the big end end face at contact head 1, uniform vertically at least 4 elongated slots.The outstanding circle outer convex rib 14 of the radial outward of the big end port of contact head 1, an inwardly outstanding circle inner convex platform 13.The inwardly outstanding circle inner convex platform 71 of the port of adapter sleeve 7, this inner convex platform 71 props up the outer convex rib 14 of described contact head 1, the inwardly outstanding circle inner convex platform 72 in the middle part of adapter sleeve 7, packing ring 8 is resisted against on described inner convex platform 72 and the described contact head step 12.

Tightening up under the state, the inner convex platform 71 of adapter sleeve 7 props up the outer convex rib 14 of described contact head 1, and contact head 1 can tightly block connected coaxial cable; When pulling outward adapter sleeve 7, spring 5 pressurizeds, the inner convex platform 71 of adapter sleeve 7 is thrown off with the outer convex rib of contact head 1 14, and contact head 1 unclamps; When the pulling force when outward disappeared, under the effect of spring 5, packing ring 9 promoted adapter sleeve 7 and moves inward, and the inner convex platform 71 of adapter sleeve 7 props up the outer convex rib 14 of contact head 1, and contact head 1 tightens up connected coaxial cable again.The utility model makes being threaded of existing radio-frequency (RF) coaxial receptacle connector into direct insertion being slidingly connected, and is easy to connect, reliable.
