Description

A kind of floating structure of connector

One, technical field:

The utility model relates to a kind of connector, especially relates to a kind of floating structure of connector.

Two, background technology:

In the background technology, because the communication technical field fast development, printed circuit board (PCB) has obtained using widely.Be connected mainly between printed circuit board plate and the plate and realize by connector.But, because the connector alignment error is inevitably, can occur axially and the radial position deviation when therefore connector cooperates in printed circuit board (PCB) in pairs, cause connector effectively not connect, perhaps damage and lost efficacy.

Three, utility model content:

The utility model provides a kind of floating structure of connector in order to solve the weak point in the above-mentioned background technology, and it can make connector self adaptation alignment error, and is simple in structure, dependable performance.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of relocation mechanism of connector is characterized in that: relocation mechanism is separately positioned on the center conductor and outer conductor of connector plug, and dielectric is between center conductor and outer conductor.

The above-mentioned relocation mechanism that is arranged on the center conductor of connector plug comprises contact pin, inner wire one, inner wire two and spring, contact pin and spring are wrapped in the inner wire one, the afterbody of inner wire one stretches in the endoporus of inner wire two, and spring places the contact pin rear end.

The above-mentioned relocation mechanism that is arranged on outer conductor comprises contact head, shell one, shell two and elastomer, contact head, shell two and elastomer are wrapped in the shell one, contact head is positioned at the front end of shell one, and elastomer places the contact head rear end, and shell two is positioned at the elastomer rear end.

Above-mentioned inner wire one is the cylindrical sleeve tubular, is surrounded on contact pin and spring, and afterbody has a spherical convex surface.

Above-mentioned elastomer is spring or reed.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, the utility model is simple in structure, and dependable performance has vast market prospect, can produce good social benefit and economic benefit.

2, the utility model can make connector self adaptation alignment error, has avoided connector to damage and has lost efficacy, and has higher reliability.

Four, description of drawings:

Fig. 1 is the structural representation of utility model;

Fig. 2 is the operational diagram of utility model.

Among the figure, 1-contact pin, 2-inner wire one, 3-inner wire two, 4-contact head, 5-dielectric one, 6-dielectric two, 7-shell one, 8-shell two, 9-elastomer, 10-spring.

Five, embodiment:

The center conductor of the utility model connector plug is provided with a relocation mechanism, is made up of four parts: contact pin, spring and two inner wires.Wherein contact pin, spring are wrapped in the front end inner wire, and elastomer places the contact pin rear end, and the inner wire afterbody of front end stretches in the endoporus of rear end inner wire; The outer conductor of connector plug is provided with a relocation mechanism, is made up of three parts: contact head, elastomer and shell.Wherein contact head, elastomer are wrapped in the shell, and contact head is positioned at the front end of shell, adopt resilient contact structure, and elastomer places the contact head rear end.When the plug and socket of connector does not align (axially and radial position deviation occurs) when plugging together, the floating structure of connector plug center conductor and outer conductor acts on simultaneously, make plug self adaptation deviation, and paired connector is effectively connected, guarantee the reliable transmission of the signal of telecommunication.

Referring to Fig. 1, floating structure comprises center conductor relocation mechanism, outer conductor relocation mechanism and dielectric three parts.The center conductor relocation mechanism comprises contact pin 1, inner wire 1, inner wire 23 and spring 10; The outer conductor relocation mechanism comprises contact head 4, elastomer 9, shell 1 and shell 28.Contact pin 1 is that step is cylindric, and an end body diameter is little, and an end body diameter is big, and the cylinder front end that diameter is little has a cambered surface; Inner wire 1 is the cylindrical sleeve tubular, is surrounded on contact pin 1 and spring 10, and its afterbody adopts resilient contact structure, and the afterbody front end has a spherical convex surface, and contact pin 1 and spring 10 are wrapped in the inner wire 1, and the afterbody of inner wire 1 stretches in the endoporus of inner wire 23.Contact head 4 is a step cylindrical sleeve tubular, and contact head 4 adopts resilient contact structure, and its front end has a cylinder convex surface; Elastomer 9 is the rubber-like entity, is positioned at contact head 4 rear ends; Spring 10 makes contact pin 1 freely to stretch; Shell 1 is the step sleeve-like, is surrounded on contact head 4, shell 28 and elastomer 9; Shell 28 is a sleeve-like, places elastomer 9 rear ends; Dielectric 1 is that step is cylindric, between inner wire 1 and contact head 4; Dielectric 26 is cylindric, between inner wire 23 and shell 28.

Referring to Fig. 2, occur under the situation of axial location deviation, plug utilizes elastomeric scalability in the outer conductor relocation mechanism to come the influence of self adaptation axial location error; Occur under the situation of radial position deviation, what contact head was subjected to the radial position deviation in the outer conductor floating structure of plug influences generation deformation, to the certain angle [alpha] of direction swing that the radial position deviation occurs; When contact head to direction when swing that the radial position deviation occurs, in the inner wire relocation mechanism of plug, the elastic construction of front end central inner conductor afterbody is subjected to oscillatory forces deformation, makes contact pin and contact head swaying direction unanimity, pendulum angle identical, thereby eliminates the influence of radial missing.
