Abstract

The invention discloses a radio-frequency coaxial contact element. The contact element comprises a plug and a socket, wherein the plug is composed of an outer plug conductor, an inner plug conductor and a plug insulator, the plug insulator is arranged between the outer plug conductor and the inner plug conductor; the socket is composed of an outer socket conductor, an inner socket conductor, a socket insulator and clamp springs, the outer socket conductor is in a circular step tube shape, an inner cavity of the outer socket conductor is an outer conductor hole, a through clamp spring groove is formed in the hole wall along the axial direction, each clamp spring is in a C-shaped tube shape, and a convex rib is arranged on the arc-shaped wall of each clamp spring along the axial direction; the socket insulator is arranged between the outer socket conductor and the inner socket conductor, the clamp springs are clamped on the outer wall of the outer socket conductor, and the convex rib is located in the clamp spring groove of the outer plug conductor; the outer plug conductor is inserted in a hole of the outer socket conductor and squeezes the convex rib of the clamp spring on the outer socket conductor. According to the invention, the rigid hole and the clamp springs are arranged, so that enough straightening power can be provided to straighten the contact element obliquely inserted so as to meet inserting requirements, and the inner conductor of the coaxial contact element can not be damaged; the coaxial contact element is simple and reliable in structure, and convenient to assemble.

Description

A kind of radio-frequency (RF) coaxial contact

Technical field

The present invention relates to the coaxial connector technical field, especially multiport connector, specifically a kind of radio-frequency (RF) coaxial contact.

Background technology

In multiport connector, due to the assembling manufacturing error, plug and jack are in the process of docking, can there is the situation of oblique cutting, consult Fig. 1, existing radio-frequency (RF) coaxial contact to cut out the mode of reed on single component, because can not providing enough correcting power, reed allow plugs and sockets be returned to the state that plugs together normally, thereby make the coaxial connector plug socket in the process of docking, can not normally plug together as requested, when oblique cutting, because the correcting power that the outer conductor reed provides is limited, cause in the process further plugged together, inner wire is improper to be plugged together, occur damaging.

Along with product, to miniaturization, modular development, the scope of multiport connector application is more and more wider.Multiport connector, by the transmission of the signal energy of original low frequency, power supply, develop into the transmission that relates to high frequency, fiber-optic signal and low-and high-frequency, power supply, optical fiber loads in mixture gradually, and performance and technology content require more and more higher.How to implant reliably the radio-frequency (RF) coaxial contact in multiport connector, become current projector's emphasis.

Implant the less contact of radio-frequency (RF) coaxial contact, particularly size in multiport connector, for example No. 10 and No. 12 radio-frequency (RF) coaxial contacts, what need to consider is how to guarantee that the radio-frequency (RF) coaxial contact not there will be damage in the process of plugs and sockets docking.

Summary of the invention

A kind of radio-frequency (RF) coaxial contact provided for the deficiencies in the prior art is provided, and it is simple and reliable for structure, easy to assembly.

The concrete technical scheme that realizes the object of the invention is:

A kind of radio-frequency (RF) coaxial contact, characteristics are that this contact comprises plug and socket, and plug and socket are pegged graft, and described plug is comprised of plug outer conductor, plug inner conductor and pin insulator, and pin insulator is located between plug outer conductor and plug inner conductor; Described socket is comprised of socket outer conductor, socket inner wire, socket insulator and jump ring, the socket outer conductor is the step cutting pattern tubular, and its inner chamber is the outer conductor hole, and hole wall is provided with the jump-ring slot of perforation vertically, jump ring is the C shaped cylindrical, is provided with vertically convex tendon on its arcwall; Described socket insulator is located between socket outer conductor and socket inner wire, and jump ring is installed on the outer wall of socket outer conductor and convex tendon is positioned at the jump-ring slot of plug outer conductor; Plug inner conductor and socket inner wire are pegged graft, and the plug outer conductor inserts in the hole of socket outer conductor and pushes the convex tendon of jump ring on the socket outer conductor.

The convex tendon both sides of described jump ring are connected with the jump ring arcwall with the disconnection of jump ring arcwall, two ends.

The present invention arranges rigidity hole and jump ring, and enough correcting power can be provided, and makes the contact correcting of oblique cutting, thereby meet, plugs together requirement, and the inner wire of coaxial contact piece will not there will be damage; It is simple and reliable for structure, easy to assembly.

Embodiment

Consult Fig. 3-5, socket 2 of the present invention is comprised of socket outer conductor 21, socket inner wire 22, socket insulator 23 and jump ring 24, socket outer conductor 21 is the step cutting pattern tubular, its inner chamber is outer conductor hole 211, hole wall is provided with the jump-ring slot 212 of perforation vertically, jump ring 24 is the C shaped cylindrical, is provided with vertically convex tendon 241 on its arcwall; Described socket insulator 23 is located between socket outer conductor 21 and socket inner wire 22, and jump ring 24 is installed on the outer wall of socket outer conductor 21 and convex tendon 241 is positioned at the jump-ring slot 212 of plug outer conductor 21; Convex tendon 241 both sides of described jump ring 24 are connected with the jump ring arcwall with the disconnection of jump ring arcwall, two ends.

Consult Fig. 2, the present invention includes plug 1 and socket 2, plug 1 is pegged graft with socket 2, described plug 1 is comprised of plug outer conductor 11, plug inner conductor 12 and pin insulator 13, plug inner conductor 12 is pegged graft with socket inner wire 22, and plug outer conductor 11 inserts in the hole 211 of socket outer conductor and pushes the convex tendon 241 of jump ring 24 on socket outer conductor 21.

The present invention changes into 211(rigidity hole, socket outer conductor hole by traditional mode that cuts out reed on single component) and the combination of jump ring 24, solved that inner wire is improper plugs together, occurs damaging this problem.In multiport connector, in the situation that plugs and sockets contact oblique cutting, owing to being the rigidity hole, enough correcting power can be provided, make plugs and sockets after the docking certain distance, play the effect of correcting, make plugs and sockets be returned to the state that plugs together normally, thereby avoided the coaxial connector plug socket to damage, particularly inner wire damages.In the present invention, jump ring 24 provides normal pressure, guarantees that the outer conductor of plugs and sockets can reliably contact.
